本发明涉及制冷领域，尤其涉及一种通过预设算法来操控冰箱显示屏旋转角度的方法及冰箱。The invention relates to the refrigeration field, in particular to a method for controlling the rotation angle of a refrigerator display screen through a preset algorithm and a refrigerator.
背景技术Background technique
冰箱通常放置在厨房中，以便于保存要烹调或已经烹调的食物，而电视机通常放置在客厅或者房间内。因此，对于用户来说，在烹调或者在处理食物的同时看电视，必须停止手下动作，然后走到有电视机的房间内，则会导致使用不便。Refrigerators are usually placed in kitchens to preserve food to be cooked or cooked, and televisions are usually placed in living rooms or rooms. Therefore, for the user, when cooking or watching TV while processing food, he must stop his hands and walk to a room with a TV, which will cause inconvenience.
并且，随着对网络兴趣的增加，用户越来越广泛地使用从网络得到的信息。由于用户在厨房进行大部分的日常劳作，他们每个人必须走到隔开的空间使用可以接入网络的电脑才能浏览网络信息。And, as interest in the network increases, users use information obtained from the network more and more widely. Since users perform most of their daily work in the kitchen, each of them must go to a separate space to use a computer that can access the network to browse network information.
为了解决上述问题，目前的做法是将可以连网显示屏直接设置在冰箱上。In order to solve the above problems, the current practice is to directly set the display screen that can be connected to the Internet on the refrigerator.
但是，目前的显示屏大多固定在冰箱本体上，由于冰箱安装位置的不同，显示屏有可能无法正对着用户，尤其是针对儿童用户，普通冰箱高度过高，儿童无法观看到显示屏的内容。此时，就需要一种可抽拉的显示屏，可以根据用户需求调整高度，并能够实现多角度旋转。However, most of the current display screens are fixed on the refrigerator body. Due to the different installation positions of the refrigerator, the display screen may not be able to face the user, especially for children. The height of ordinary refrigerators is too high, and children cannot watch the content of the display screen. . At this time, a pullable display screen is required, which can adjust the height according to user needs and can realize multi-angle rotation.
现有技术中，可抽拉的显示屏只能通过用户手动调控显示屏位置来使得显示屏面对用户，操作起来相当不方便，用户体验较差。In the prior art, the drawable display screen can only be manually adjusted by the user to make the display screen face the user, which is quite inconvenient to operate and has poor user experience.

具体实施方式detailed description
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
本发明的显示屏包括多种操控方法及多种冰箱结构，多种操控方法及多种冰箱结构之间可以相互组合，下面以三种实施方式为例说明本发明的显示屏的操控方法及冰箱。The display screen of the present invention includes multiple control methods and multiple refrigerator structures, which can be combined with each other. The following three implementation modes are used as examples to illustrate the control method of the display screen and the refrigerator of the present invention. .
参图1及图2，为本发明第一实施方式的通过麦克风识别以操控冰箱显示屏的方法，所述方法包括步骤：Referring to Fig. 1 and Fig. 2, it is a method for controlling the display screen of a refrigerator through microphone recognition according to the first embodiment of the present invention. The method includes steps:
接收声源A；Receive sound source A;
将所述声源A与预设的声源库B进行匹配，得到所述声源A对应的用户身份信息Y；Matching the sound source A with the preset sound source library B to obtain the user identity information Y corresponding to the sound source A;
根据所述用户身份信息Y将所述显示屏100调节至对应高度H。The display screen 100 is adjusted to a corresponding height H according to the user identity information Y.
这里，如图2所示，显示屏100的周缘区域设置有至少一麦克风，这里以设置于显示屏100左右两侧的第一麦克风101及第二麦克风102为例，所述第一麦克风101及所述第二麦克风102的高度相同，第一麦克风101及第二麦克风102用于接收一定范围内的声源。Here, as shown in FIG. 2 , at least one microphone is provided in the peripheral area of the display screen 100. Here, the first microphone 101 and the second microphone 102 arranged on the left and right sides of the display screen 100 are taken as an example. The first microphone 101 and The heights of the second microphones 102 are the same, and the first microphone 101 and the second microphone 102 are used to receive sound sources within a certain range.
麦克风的数量及位置可以根据实际情况而定，不以上述说明为限。The number and positions of the microphones may be determined according to actual conditions, and are not limited to the above description.
冰箱内部可预存有声源库B，例如，当冰箱为家用冰箱时，声源库B可以包括男主人、女主人、儿童等的声源信息，此时，用户身份信息Y即为男主人、女主人、儿童等。The sound source library B can be pre-stored inside the refrigerator. For example, when the refrigerator is a household refrigerator, the sound source library B can include the sound source information of the host, hostess, children, etc. At this time, the user identity information Y is the host, female Master, children, etc.
但不以此为限，例如，当冰箱为公共场合的冰箱时，声源库B可以包括男性、女性、儿童等的声源信息。But it is not limited thereto. For example, when the refrigerator is a refrigerator in a public place, the sound source library B may include sound source information of men, women, children, and so on.
另外，冰箱内还可预存有适应每一用户身份信息Y的显示屏100高度H，例如，当男主人的身高为180cm时，其预存的对应的显示屏100高度H可以为175cm，此时，当判断用户身份信息Y为男主人时，便可以直接将显示屏100的高度H调节至175cm。In addition, the height H of the display screen 100 adapted to each user's identity information Y can also be pre-stored in the refrigerator. For example, when the height of the male owner is 180 cm, the corresponding height H of the display screen 100 pre-stored can be 175 cm. At this time, When it is judged that the user identity information Y is the male host, the height H of the display screen 100 can be directly adjusted to 175 cm.
具体的，在一示例中，声源库B中储存有男声、女声及童声，其通过音色、音调等信息进行区分，且用户身份信息Y对应的声源A为男声时对应第一高度H1，用户身份信息Y对应的声源A为女声时对应第二高度H2，用户身份信息Y对应的声源A为童声时对应第三高度H3，所述第一高度H1、所述第二高度H2及所述第三高度H3不同，例如，第一高度H1设置为175cm，第二高度H2设置为160cm，第三高度H3设置为80cm。Specifically, in an example, male voices, female voices, and child voices are stored in the sound source library B, which are distinguished by information such as timbre, pitch, and the first height H1 when the sound source A corresponding to the user identity information Y is a male voice. When the sound source A corresponding to the user identity information Y is a female voice, it corresponds to the second height H2, when the sound source A corresponding to the user identity information Y is a child voice, it corresponds to the third height H3, the first height H1, the second height H2 and The third height H3 is different, for example, the first height H1 is set to 175 cm, the second height H2 is set to 160 cm, and the third height H3 is set to 80 cm.
将接收到的所述声源A与预设的声源库B进行匹配，若所述声源A为男声，则将所述显示屏100调节至第一高度H1；若所述声源A为女声，则将所述显示屏100调节至第二高度H2；若所述声源A为童声，则将所述显示屏100调节至第三高度H3。Matching the received sound source A with the preset sound source library B, if the sound source A is a male voice, then adjust the display screen 100 to the first height H1; if the sound source A is If the voice is female, adjust the display screen 100 to the second height H2; if the sound source A is a child voice, adjust the display screen 100 to the third height H3.
在另一示例中，声源库B中预存有若干主人声源及每一主人声源对应的预设高度，例如，主人身份信息Y主为男主人时对应男主人高度H男，主人身份信息Y主为女主人时对应女主人高度H女，主人身份信息Y主为儿童时对应儿童高度H童。In another example, several master sound sources and the presetheights corresponding to eachmaster sound source are pre-stored in the sound source library B. When theowner of Y is the hostess, it corresponds to the height of thehostess H, and when the identity information ofthe host is the child, the height of thechild is H.
这里，男主人高度H男、女主人高度H女、儿童高度H童为对应用户所预设的显示屏高度H。Here, the height H of the host, the height H of thehostess ,and the height H of thechild are the height H of the display screen preset by the corresponding user.
将接收到的所述声源A与预设的声源库B进行匹配，若匹配到为预存的若干主人声源中的一个（即匹配成功），则根据主人身份信息Y主将所述显示屏100调节至对应的高度；若匹配到不是预存的若干主人声源中的一个（即匹配失败），则判断所述声源A的类别，后续的操作可以参考上一示例，即，若所述声源A为男声，则将所述显示屏100调节至第一高度H1，若所述声源A为女声，则将所述显示屏100调节至第二高度H2，若所述声源A为童声，则将所述显示屏100调节至第三高度H3。Match the received sound source A with the preset sound source library B. If it is matched to one of the pre-stored sound sources of the owner (that is, the match is successful), the display will be displayed according to the owner’s identity informationY. Adjust the screen 100 to the corresponding height; if it is not matched to one of the pre-stored master sound sources (that is, the match fails), then judge the category of the sound source A, and the subsequent operations can refer to the previous example, that is, if the If the sound source A is a male voice, adjust the display screen 100 to the first height H1, if the sound source A is a female voice, then adjust the display screen 100 to the second height H2, if the sound source A If it is a child's voice, adjust the display screen 100 to the third height H3.
当然，当匹配失败时，也可通过其他方式进行调节。例如，若所述声源A为男声，则默认用户与男主人身高相同，此时将显示屏调节至男主人高度H男，以此类推，当为女声或童声时可以进行相应的调节。Of course, when the matching fails, adjustments can also be made in other ways. For example, if the sound source A is a male voice, the default user is the same height as the male host. At this time, the display screen is adjusted to the height H of themale host. By analogy, corresponding adjustments can be made when it is a female voice or a child voice.
综上所述，本实施方式中可以预存有声源库B、用户身份信息Y及对应的所需高度H等信息，如此，当接收到声源后，便可通过内部分析直接得到用户身份信息Y，而后根据用户身份信息Y便可直接进行显示屏100高度H的调节，调节过程简单便捷，且可适应不同的用户，用户体验极佳。To sum up, in this embodiment, information such as the sound source library B, user identity information Y and the corresponding required height H can be pre-stored, so that when the sound source is received, the user identity information Y can be directly obtained through internal analysis , and then according to the user identity information Y, the height H of the display screen 100 can be directly adjusted. The adjustment process is simple and convenient, and can be adapted to different users, and the user experience is excellent.
在本实施方式中，步骤“接收声源A”具体包括：In this embodiment, the step "receiving sound source A" specifically includes:
第一麦克风101及第二麦克风102接收声源A；The first microphone 101 and the second microphone 102 receive the sound source A;
分别获取所述第一麦克风101的第一接收时间T1及所述第二麦克风102的第二接收时间T2；respectively acquiring a first receiving time T1 of the first microphone 101 and a second receiving time T2 of the second microphone 102;
判断所述第一接收时间T1是否小于所述第二接收时间T2，若是，则根据所述第一接收时间T1调节所述显示屏100的水平伸出距离，若否，则根据第二接收时间T2调节所述显示屏100的水平伸出距离。Judging whether the first receiving time T1 is less than the second receiving time T2, if so, adjusting the horizontal extension distance of the display screen 100 according to the first receiving time T1, if not, adjusting the horizontal extension distance of the display screen 100 according to the second receiving time T2 adjusts the horizontal extension distance of the display screen 100 .
这里，结合图2，当第一接收时间T1小于第二接收时间T2时，即表明此时用户与第一麦克风101之间的第一距离S1小于用户与第二麦克风102之间的第二距离S2，判定此时用户位于冰箱的靠近第一麦克风101的一侧，且用户与第一麦克风101之间的斜向距离为S1=T1*V声，其中，声音的传播速度大约为340m/s。Here, referring to FIG. 2, when the first receiving time T1 is less than the second receiving time T2, it means that the first distance S1 between the user and the first microphone 101 is smaller than the second distance between the user and the second microphone 102 at this time. S2. It is determined that the user is located on the side of the refrigerator close to the first microphone 101 at this time, and the oblique distance between the user and the first microphone 101 is S1=T1*Vsound , where the sound propagation speed is about 340m/s .
此时，控制显示屏100水平向外移动距离S=X*S1，其中，X的取值范围为0.5~0.7，且向外移动的距离S不可超过显示屏100可以向外延伸的最大距离，如此，可保证显示屏100朝向用户水平移动，且确保显示屏100与用户之间仍有一定距离。At this time, the control display screen 100 moves outward horizontally by a distance S=X*S1, wherein the value range of X is 0.5-0.7, and the distance S to be moved outward cannot exceed the maximum distance that the display screen 100 can extend outward. In this way, it can be ensured that the display screen 100 moves horizontally toward the user, and there is still a certain distance between the display screen 100 and the user.
显示屏100水平向外移动距离S大致可为8~15cm，但不以此为限。The horizontal outward movement distance S of the display screen 100 may be approximately 8-15 cm, but not limited thereto.
当显示屏100水平向外移动一定距离后，后续可继续根据用户身份信息Y在竖直方向上调节显示屏100的高度。After the display screen 100 moves outward for a certain distance horizontally, the height of the display screen 100 can be adjusted in the vertical direction according to the user identity information Y subsequently.
可以理解，显示屏100水平方向及竖直方向的调节没有一定的先后顺序，可根据实际情况而定。It can be understood that the adjustment of the horizontal direction and the vertical direction of the display screen 100 is not in a certain order, and may be determined according to actual conditions.
另外，在本实施方式中，由于用户很多情况下不在冰箱的正中间，用户极有可能位于冰箱的左侧或右侧。In addition, in this embodiment, since the user is not in the middle of the refrigerator in many cases, the user is likely to be located on the left or right side of the refrigerator.
因此，当控制显示屏100水平向外移动距离S时，同时也可控制显示屏100的左右移动。例如，当第一接收时间T1小于第二接收时间T2时，即表明此时用户位于第一麦克风101侧，则此时可以控制显示屏向第一麦克风101的方向偏移一定距离，即此时图2中的显示屏100向图片的右侧偏移一定距离，偏移的距离可以根据第一接收时间T1而定，但不以此为限。Therefore, when the display screen 100 is controlled to move horizontally outward by the distance S, the left and right movement of the display screen 100 can also be controlled at the same time. For example, when the first receiving time T1 is less than the second receiving time T2, it means that the user is at the side of the first microphone 101 at this time, and at this time the display screen can be controlled to shift a certain distance in the direction of the first microphone 101, that is, at this time The display screen 100 in FIG. 2 is shifted to the right side of the picture by a certain distance, and the shift distance may be determined according to the first receiving time T1, but is not limited thereto.
可以理解，显示屏100的左右偏移及水平向前移动可以同时实现。It can be understood that the horizontal shift and horizontal forward movement of the display screen 100 can be realized simultaneously.
在本实施方式中，步骤“第一麦克风101及第二麦克风102接收声源A”之后还包括：In this embodiment, after the step "the first microphone 101 and the second microphone 102 receive the sound source A" further includes:
判断所述声源A是否为预设弹出信号，若是，则进入下一步骤；若否，则所述第一麦克风101及所述第二麦克风102继续接收声源。Judging whether the sound source A is a preset pop-up signal, if yes, proceed to the next step; if not, the first microphone 101 and the second microphone 102 continue to receive the sound source.
这里，例如可以在冰箱内预设弹出信号，例如为语音信号“我要看电视”，当用户说出“我要看电视”这句话时，冰箱便默认识别到了预设弹出信号，此时，可以进行显示屏100的调节。Here, for example, a pop-up signal can be preset in the refrigerator, such as the voice signal "I want to watch TV". When the user says "I want to watch TV", the refrigerator recognizes the preset pop-up signal by default. , the display screen 100 can be adjusted.
需要说明的是，当识别到预设弹出信号后，冰箱可以先控制显示屏100脱离冰箱内部其他限位结构的限制，即此时显示屏100可以进行多方向的调节操作，而后再根据用户身份信息Y、第一接收时间T1、第二接收时间T2等进行显示屏100水平方向及竖直方向的位置调节。It should be noted that when the preset pop-up signal is recognized, the refrigerator can first control the display screen 100 to break away from the restrictions of other limiting structures inside the refrigerator, that is, the display screen 100 can perform multi-directional adjustment operations at this time, and then adjust the display screen 100 according to the identity of the user. The information Y, the first receiving time T1, the second receiving time T2, etc. are used to adjust the horizontal and vertical positions of the display screen 100 .
当然，在其他实施方式中，当识别到预设弹出信号后，冰箱可以先进行用户身份信息Y的识别，当识别成功后，再控制显示屏100脱离冰箱内部其他限位结构的限制。Certainly, in other implementation manners, when the preset pop-up signal is recognized, the refrigerator may first identify the user identity information Y, and then control the display screen 100 to break away from other limiting structures inside the refrigerator after the identification is successful.
也就是说，本实施方式中各个信号的识别、匹配过程并没有明确的先后关系，可以根据实际情况而定。That is to say, the identification and matching process of each signal in this implementation manner does not have a clear sequence, and may be determined according to actual conditions.
在本实施方式中，当完成显示屏100水平方向及竖直方向的调节之后，显示屏100还是呈竖直摆放，即此时显示屏100的屏幕与冰箱的前表面为平行状态。为了使得显示屏100与用户位置更加匹配，此时还进行如下操作：In this embodiment, after the adjustment of the horizontal direction and the vertical direction of the display screen 100 is completed, the display screen 100 is still placed vertically, that is, the screen of the display screen 100 is parallel to the front surface of the refrigerator. In order to make the display screen 100 more match the user's position, the following operations are also performed at this time:
捕获用户影像；capture user images;
控制所述显示屏100转动以使得始终能捕获到所述用户影像。The rotation of the display screen 100 is controlled so that the image of the user can always be captured.
具体的，参图2，此时显示屏100上还设有摄像头103，摄像头103用于捕捉用户影像，当用户移动时，摄像头103带动显示屏100一起转动，直至摄像头103识别到的用户影像位于摄像头的中间位置，如此，可以保证显示屏100实时正对用户，提高用户体验。Specifically, referring to FIG. 2, at this time, the display screen 100 is also provided with a camera 103, which is used to capture user images. When the user moves, the camera 103 drives the display screen 100 to rotate together until the user image recognized by the camera 103 is located at The middle position of the camera, in this way, can ensure that the display screen 100 faces the user in real time, improving user experience.
本实施方式还设置有运动检测单元（未图示），其用于判断用户的运动幅度，若所述运动幅度大于运动阈值，则控制所述显示屏100转动以使得摄像头103始终能捕获到所述用户影像，若所述运动幅度不大于运动阈值，则所述显示屏100不转动。This embodiment is also provided with a motion detection unit (not shown), which is used to judge the range of motion of the user. If the range of motion is greater than the motion threshold, the display screen 100 is controlled to rotate so that the camera 103 can always capture all For the user image, if the motion range is not greater than the motion threshold, the display screen 100 does not rotate.
如此，可以避免显示屏100过于频繁的转动而导致显示屏100结构不稳定或是冰箱功耗高。In this way, too frequent rotation of the display screen 100 can be avoided, resulting in an unstable structure of the display screen 100 or high power consumption of the refrigerator.
在本实施方式中，还涉及显示屏100复位的过程。In this embodiment, the process of resetting the display screen 100 is also involved.
例如，可通过摄像头103捕捉用户影像，当超过一预设时间而未捕捉到用户影像时，即表明此时用户已经离开，可以控制显示屏100复位。For example, the user's image can be captured by the camera 103, and when the user's image is not captured for a preset time, it means that the user has left at this time, and the display screen 100 can be controlled to reset.
又例如是，在冰箱上设置一探测器，所述探测器可探测在一定范围内是否有用户存在，当探测器超过一预设时间未探测到有用户存在时，即表明此时用户已经离开，可以控制显示屏100复位。Another example is that a detector is set on the refrigerator, and the detector can detect whether there is a user within a certain range. When the detector does not detect the presence of a user for more than a preset time, it means that the user has left at this time. , can control the reset of the display screen 100 .
再例如是，在冰箱上设置一复位按钮，当用户要离开时，按动复位按钮便可实现显示屏100的复位。For another example, a reset button is set on the refrigerator, and when the user wants to leave, the display screen 100 can be reset by pressing the reset button.
需要说明的是，上述提到的显示屏100的调节、复位等操作也可加入用户的人工调节，使其更加符合用户需求。It should be noted that, the above-mentioned operations such as adjustment and reset of the display screen 100 can also be manually adjusted by the user to make it more in line with the needs of the user.
显示屏100相对于冰箱可根据用户指令弹出后，与摄像头103结合，根据用户实际高度调整显示屏100后部折叠机构运动，不论成人或儿童，都能有较好的用户体验，并能够实现实时跟踪用户位置来旋转显示屏100旋转角度，折叠机构之间存在阻尼连接，能够保证在运动或静止过程中不会发生显示屏100晃动，影响其稳定性及观影感受。The display screen 100 can be popped up relative to the refrigerator according to the user's instruction, and combined with the camera 103, the movement of the rear folding mechanism of the display screen 100 can be adjusted according to the user's actual height, so that both adults and children can have a better user experience and can realize real-time The rotation angle of the display screen 100 is tracked by tracking the user's position, and there is a damping connection between the folding mechanisms, which can ensure that the display screen 100 will not shake during motion or static, affecting its stability and viewing experience.
本发明第一实施方式还提供一种冰箱，参考图1至图2及上述说明，所述冰箱包括冰箱本体、与所述冰箱本体活动连接的显示屏100、至少一麦克风及控制单元（未图示），这里以左右两个麦克风为例。The first embodiment of the present invention also provides a refrigerator.

这里，可以预存有声源库B、用户身份信息Y及对应的所需高度H等信息，如此，当接收到声源后，便可通过内部分析直接得到用户身份信息Y，而后根据用户身份信息Y便可直接进行显示屏100高度H的调节，调节过程简单便捷，且可适应不同的用户，用户体验极佳。Here, information such as the sound source library B, user identity information Y and the corresponding required height H can be pre-stored, so that when the sound source is received, the user identity information Y can be directly obtained through internal analysis, and then according to the user identity information Y The height H of the display screen 100 can be directly adjusted, the adjustment process is simple and convenient, and it can be adapted to different users, and the user experience is excellent.
所述冰箱还包括设置于所述显示屏100上的摄像头103，所述摄像头103用于捕获用户影像，当所述显示屏100调节至对应高度后，所述控制单元控制所述显示屏100转动以使得所述摄像头103可以始终捕获所述用户影像。The refrigerator also includes a camera 103 arranged on the display screen 100, the camera 103 is used to capture user images, and when the display screen 100 is adjusted to a corresponding height, the control unit controls the display screen 100 to rotate So that the camera 103 can always capture the image of the user.
如此，可以保证显示屏100实时正对用户，提高用户体验。In this way, it can be ensured that the display screen 100 faces the user in real time, improving user experience.
本实施方式的冰箱的其他说明可以参考上述第一实施方式的通过麦克风识别以操控冰箱显示屏的方法的说明，在此不再赘述。For other descriptions of the refrigerator in this embodiment, reference may be made to the description of the method for controlling the display screen of the refrigerator through microphone recognition in the above-mentioned first embodiment, and details are not repeated here.
参图3，为第一实施方式的一具体实施例。Referring to Fig. 3, it is a specific example of the first embodiment.
假设显示屏100于冰箱预埋盒内时的高度H为H0，H0为显示屏100中心距离地面的距离；第一麦克风101、第二麦克风102分别设置于冰箱的两侧，冰箱内预存有声源库B及预设弹出信号。Assume that the height H of the display screen 100 in the refrigerator pre-embedded box is H0 , and H0 is the distance from the center of the display screen 100 to the ground; the first microphone 101 and the second microphone 102 are respectively installed on both sides of the refrigerator, and the There are sound source bank B and preset pop-up signals.

上述仅是第一实施方式的一具体实施例，并不以上述具体实施例为限。The above is only a specific example of the first embodiment, and is not limited to the above specific example.
参图4及图5，为本发明第二实施方式的通过预设用户优先级别来操控冰箱显示屏的方法，这里，与第一实施方式相同的元素采用相同的编号。Referring to FIG. 4 and FIG. 5 , it is a method for controlling the display screen of a refrigerator by preset user priority levels according to the second embodiment of the present invention. Here, the same elements as those in the first embodiment use the same numbers.
所述方法包括步骤：The method comprises the steps of:
接收声源A；Receive sound source A;
将所述声源A与预设的用户优先级别C进行匹配，判断所述声源A对应的用户是否为最高优先级别用户Y’，若是，则根据所述最高优先级别用户Y’的身份信息将所述显示屏调节至对应高度；若否，则继续接收声源。Match the sound source A with the preset user priority C, and judge whether the user corresponding to the sound source A is the highest priority user Y', and if so, according to the identity information of the highest priority user Y' Adjust the display screen to the corresponding height; if not, continue to receive the sound source.
这里，如图5所示，显示屏100的周缘区域设置有至少一麦克风，这里以设置于显示屏100左右两侧的第一麦克风101及第二麦克风102为例，第一麦克风101及第二麦克风102用于接收一定范围内的声源。Here, as shown in FIG. 5 , at least one microphone is provided on the peripheral area of the display screen 100. Here, taking the first microphone 101 and the second microphone 102 arranged on the left and right sides of the display screen 100 as an example, the first microphone 101 and the second microphone The microphone 102 is used to receive sound sources within a certain range.
麦克风的数量及位置可以根据实际情况而定，不以上述说明为限。The number and positions of the microphones may be determined according to actual conditions, and are not limited to the above description.
冰箱内部可预存有用户优先级别C，例如，当冰箱为家用冰箱时，用户优先级别C可为女主人的优先级别高于男主人，男主人的优先级别高于儿童，此时，最高优先级别用户Y’便是女主人。The user priority level C can be pre-stored inside the refrigerator. For example, when the refrigerator is a household refrigerator, the user priority level C can be that the priority level of the hostess is higher than that of the male owner, and the priority level of the male owner is higher than that of children. At this time, the highest priority level User Y' is the hostess.
另外，冰箱内还可预存有适应每一用户的显示屏100高度H，例如，当女主人的身高为165cm时，其预存的对应的显示屏100高度H可以为160cm，此时，当判断声源A为最高优先级别用户Y’的女主人的声源时，便可以直接将显示屏100的高度H调节至160cm。In addition, the height H of the display screen 100 adapted to each user can also be pre-stored in the refrigerator. For example, when the height of the hostess is 165 cm, the corresponding height H of the display screen 100 pre-stored can be 160 cm. When the source A is the sound source of the hostess of the highest priority user Y', the height H of the display screen 100 can be directly adjusted to 160 cm.
本实施方式中，还包括有声源库B，以进行用户身份的识别。In this embodiment, a sound source library B is also included to identify the identity of the user.
具体的，在一示例中，声源库B中储存有男声、女声及童声，其通过音色、音调等信息进行区分，且用户身份信息对应的声源A为男声时对应第一高度H1，用户身份信息对应的声源A为女声时对应第二高度H2，用户身份信息对应的声源A为童声时对应第三高度H3，所述第一高度H1、所述第二高度H2及所述第三高度H3不同，例如，第一高度H1设置为175cm，第二高度H2设置为160cm，第三高度H3设置为80cm。Specifically, in an example, male voices, female voices, and child voices are stored in the sound source library B, which are distinguished by information such as timbre, pitch, etc., and when the sound source A corresponding to the user identity information is a male voice, it corresponds to the first height H1. When the sound source A corresponding to the identity information is a female voice, it corresponds to the second height H2. When the sound source A corresponding to the user identity information is a child voice, it corresponds to the third height H3. The first height H1, the second height H2 and the second height The three heights H3 are different, for example, the first height H1 is set to 175 cm, the second height H2 is set to 160 cm, and the third height H3 is set to 80 cm.
将接收到的所述声源A与预设的声源库B进行匹配，若所述声源A为女声，将女声与用户优先级别C进行匹配，若女声对应的用户不是最高优先级别用户Y’，则不进行显示屏100的调节，若女声对应的用户是最高优先级别用户Y’，则将所述显示屏100调节至第二高度H2。Match the received sound source A with the preset sound source library B. If the sound source A is a female voice, match the female voice with user priority C. If the user corresponding to the female voice is not the highest priority user Y ', the display screen 100 is not adjusted, and if the user corresponding to the female voice is the highest priority user Y', the display screen 100 is adjusted to the second height H2.
需要说明的是，声源库B及用户优先级别C的匹配可以同时进行，但不以此为限。It should be noted that the matching of the sound source library B and the user priority level C can be performed simultaneously, but not limited thereto.
在另一示例中，声源库B中预存有若干主人声源及每一主人声源对应的预设高度，例如，主人身份信息Y主为男主人时对应男主人高度H男，主人身份信息Y主为女主人时对应女主人高度H女，主人身份信息Y主为儿童时对应儿童高度H童。In another example, several master sound sources and the presetheights corresponding to eachmaster sound source are pre-stored in the sound source library B. When theowner of Y is the hostess, it corresponds to the height of thehostess H, and when the identity information ofthe host is the child, the height of thechild is H.
这里，男主人高度H男、女主人高度H女、儿童高度H童为对应用户所预设的显示屏高度H。Here, the height H of the host, the height H of thehostess ,and the height H of thechild are the height H of the display screen preset by the corresponding user.
将接收到的所述声源A与预设的声源库B进行匹配，若匹配到为预存的若干主人声源中的一个（即匹配成功），则再进行用户优先级别C的匹配，若匹配到声源对应的用户是最高优先级别用户Y’，则进行显示屏100的调节，若不是，则不进行显示屏100的调节。Match the received sound source A with the preset sound source library B, if it is matched to one of the pre-stored master sound sources (that is, the matching is successful), then match the user priority level C, if If it is matched that the user corresponding to the sound source is the user Y' with the highest priority, the adjustment of the display screen 100 will be performed; if not, the adjustment of the display screen 100 will not be performed.
若匹配到不是预存的若干主人声源中的一个（即匹配失败），则判断所述声源A的类别，若所述声源A为女声，则默认用户为女主人，则再进行用户优先级别C的匹配，若匹配到声源对应的用户是最高优先级别用户Y’，则进行显示屏100的调节，若不是，则不进行显示屏100的调节。但不以此为限。If the matching is not one of the pre-stored master voice sources (that is, the matching fails), the category of the voice source A is judged. If the voice source A is a female voice, the default user is the hostess, and then the user is prioritized. For level C matching, if the user corresponding to the sound source is the user Y' with the highest priority level, the adjustment of the display screen 100 will be performed; if not, the adjustment of the display screen 100 will not be performed. But not limited to this.
综上所述，本实施方式中可以预存有用户优先级别C、声源库B及对应的所需高度H等信息，如此，当接收到声源A后，便可通过内部分析直接得到声源A对应的用户是否为最高优先级别用户Y’，若是，则将显示屏100高度H调节至所需高度，若否，则不进行显示屏100的调节。如此，可以有效提高冰箱的使用智能化，例如，可以将儿童的优先级降低，从而避免儿童胡乱使用冰箱显示屏或是儿童长时间操作冰箱显示屏100。To sum up, in this embodiment, information such as user priority level C, sound source library B and the corresponding required height H can be pre-stored, so that after receiving sound source A, the sound source can be directly obtained through internal analysis Whether the user corresponding to A is the highest priority user Y′, if so, adjust the height H of the display screen 100 to the required height, if not, do not adjust the display screen 100 . In this way, the intelligent use of the refrigerator can be effectively improved, for example, the priority of children can be lowered, so as to prevent children from using the display screen of the refrigerator indiscriminately or children from operating the display screen 100 of the refrigerator for a long time.
在本实施方式中，当判断所述声源A对应的用户不是最高优先级别用户Y’时，还包括步骤：In this embodiment, when it is judged that the user corresponding to the sound source A is not the highest priority user Y', further steps are included:
判断是否接收到所述最高优先级别用户Y’发出的用户级别更换指令，若是，则将用户优先级别C变更为新的用户优先级别C’，并继续接收声源A及将所述声源A与新的用户优先级别C’进行匹配；若否，则继续接收声源。Judging whether the user level replacement instruction issued by the highest priority user Y' has been received, if so, change the user priority level C to a new user priority level C', and continue to receive sound source A and change the sound source A Match with the new user priority level C'; if not, continue to receive the sound source.
这里，用户级别更换指令例如为最高级别优先级用户Y’发出语音“接收其他人命令”，则此时将预存的用户优先级别C变更为新的用户优先级别C’，系统可以默认将最高级别优先级用户Y’变更为原先用户优先级别C中的次高优选级别用户，但不以此为限，最高级别优先级用户Y’也可指定新的用户优先级别C’顺序。Here, the user level replacement instruction is for example, the highest level priority user Y' sends a voice "receive other people's orders", then at this time, the pre-stored user priority level C is changed to the new user priority level C', and the system can default the highest level The priority user Y' is changed to the second highest priority user in the original user priority C, but not limited thereto, the highest priority user Y' can also specify a new order of user priority C'.
另外，新的用户优先级别C’的使用时间可以为一预定时间，也就是说，仅在该预定时间内，新的用户优先级别C’中设定的最高优先级别用户Y’可以操控显示屏100，超过该预定时间，新的用户优先级别C’又变更为原先的用户优先级别C。In addition, the use time of the new user priority C' can be a predetermined time, that is, only within the predetermined time, the user Y' with the highest priority set in the new user priority C' can manipulate the display screen 100. After the preset time, the new user priority level C' is changed to the original user priority level C again.
例如，该预定时间设为30分钟，新的用户优先级别C’中儿童为最高优先级别用户Y’，那么，在这30分钟内显示屏100可以听从儿童的指令，超过30分钟儿童便不能再操控显示屏100。For example, if the predetermined time is set to 30 minutes, and children are the highest priority user Y' in the new user priority level C', then, within these 30 minutes, the display screen 100 can obey the instructions of the children, and the children can no longer follow the instructions of the children within 30 minutes. The display screen 100 is manipulated.
如此的设计，可以实现显示屏100的灵活控制，也有效辅助家长调控儿童的娱乐时间。Such a design can realize the flexible control of the display screen 100, and also effectively assist parents in controlling children's entertainment time.
在本实施方式中，步骤“接收声源A”具体包括：In this embodiment, the step "receiving sound source A" specifically includes:
第一麦克风101及第二麦克风102接收声源A；The first microphone 101 and the second microphone 102 receive the sound source A;
分别获取所述第一麦克风101的第一接收时间T1及所述第二麦克风102的第二接收时间T2；respectively acquiring a first receiving time T1 of the first microphone 101 and a second receiving time T2 of the second microphone 102;
判断所述第一接收时间T1是否小于所述第二接收时间T2，若是，则根据所述第一接收时间T1调节所述显示屏100的水平伸出距离，若否，则根据第二接收时间T2调节所述显示屏100的水平伸出距离。Judging whether the first receiving time T1 is less than the second receiving time T2, if so, adjusting the horizontal extension distance of the display screen 100 according to the first receiving time T1, if not, adjusting the horizontal extension distance of the display screen 100 according to the second receiving time T2 adjusts the horizontal extension distance of the display screen 100 .
这里，结合图5，当第一接收时间T1小于第二接收时间T2时，即表明此时用户与第一麦克风101之间的第一距离S1小于用户与第二麦克风102之间的第二距离S2，判定此时用户位于冰箱的靠近第一麦克风101的一侧，且用户与第一麦克风101之间的斜向距离为S1=T1*V声，其中，声音的传播速度大约为340m/s。Here, referring to FIG. 5 , when the first receiving time T1 is less than the second receiving time T2, it means that the first distance S1 between the user and the first microphone 101 is smaller than the second distance between the user and the second microphone 102 at this time. S2. It is determined that the user is located on the side of the refrigerator close to the first microphone 101 at this time, and the oblique distance between the user and the first microphone 101 is S1=T1*Vsound , where the sound propagation speed is about 340m/s .
此时，控制显示屏100水平向外移动距离S=X*S1，其中，X的取值范围为0.5~0.7，且向外移动的距离S不可超过显示屏100可以向外延伸的最大距离，如此，可保证显示屏100朝向用户水平移动，且确保显示屏100与用户之间仍有一定距离。At this time, the control display screen 100 moves outward horizontally by a distance S=X*S1, wherein the value range of X is 0.5-0.7, and the distance S to be moved outward cannot exceed the maximum distance that the display screen 100 can extend outward. In this way, it can be ensured that the display screen 100 moves horizontally toward the user, and there is still a certain distance between the display screen 100 and the user.
显示屏100水平向外移动距离S大致可为8~15cm，但不以此为限。The horizontal outward movement distance S of the display screen 100 may be approximately 8-15 cm, but not limited thereto.
当显示屏100水平向外移动一定距离后，后续可继续根据用户身份信息Y在竖直方向上调节显示屏100的高度。After the display screen 100 moves outward for a certain distance horizontally, the height of the display screen 100 can be adjusted in the vertical direction according to the user identity information Y subsequently.
可以理解，显示屏100水平方向及竖直方向的调节没有一定的先后顺序，可根据实际情况而定。It can be understood that the adjustment of the horizontal direction and the vertical direction of the display screen 100 is not in a certain order, and may be determined according to actual conditions.
另外，在本实施方式中，由于用户很多情况下不在冰箱的正中间，用户极有可能位于冰箱的左侧或右侧。In addition, in this embodiment, since the user is not in the middle of the refrigerator in many cases, the user is likely to be located on the left or right side of the refrigerator.
因此，当控制显示屏100水平向外移动距离S时，同时也可控制显示屏100的左右移动。例如，当第一接收时间T1小于第二接收时间T2时，即表明此时用户位于第一麦克风101侧，则此时可以控制显示屏向第一麦克风101的方向偏移一定距离，即此时图5中的显示屏100向图片的右侧偏移一定距离，偏移的距离可以根据第一接收时间T1而定，但不一次为限。Therefore, when the display screen 100 is controlled to move horizontally outward by the distance S, the left and right movement of the display screen 100 can also be controlled at the same time. For example, when the first receiving time T1 is less than the second receiving time T2, it means that the user is at the side of the first microphone 101 at this time, and at this time the display screen can be controlled to shift a certain distance in the direction of the first microphone 101, that is, at this time The display screen 100 in FIG. 5 is shifted to the right side of the picture by a certain distance, and the shift distance may be determined according to the first receiving time T1, but not limited to one time.
可以理解，显示屏100的左右偏移及水平向前移动可以同时实现。It can be understood that the horizontal shift and horizontal forward movement of the display screen 100 can be realized simultaneously.
在本实施方式中，步骤“第一麦克风101及第二麦克风102接收声源A”之后还包括：In this embodiment, after the step "the first microphone 101 and the second microphone 102 receive the sound source A" further includes:
判断所述声源A是否为预设弹出信号，若是，则进入下一步骤；若否，则所述第一麦克风101及所述第二麦克风102继续接收声源。Judging whether the sound source A is a preset pop-up signal, if yes, proceed to the next step; if not, the first microphone 101 and the second microphone 102 continue to receive the sound source.
这里，例如可以在冰箱内预设弹出信号，例如为语音信号“我要看电视”，当用户说出“我要看电视”这句话时，冰箱便默认识别到了预设弹出信号，此时，可以进行显示屏100的调节。Here, for example, a pop-up signal can be preset in the refrigerator, such as the voice signal "I want to watch TV". When the user says "I want to watch TV", the refrigerator recognizes the preset pop-up signal by default. , the display screen 100 can be adjusted.
需要说明的是，当识别到预设弹出信号后，冰箱可以先控制显示屏100脱离冰箱内部其他限位结构的限制，即此时显示屏100可以进行多方向的调节操作，而后再根据最高优先级别用户Y’的身份信息、第一接收时间T1、第二接收时间T2等进行显示屏100水平方向及竖直方向的位置调节。It should be noted that when the preset pop-up signal is recognized, the refrigerator can first control the display screen 100 to break away from the restrictions of other limiting structures inside the refrigerator, that is, the display screen 100 can perform multi-directional adjustment operations at this time, and then adjust according to the highest priority. The identity information of the level user Y', the first receiving time T1, the second receiving time T2, etc. are used to adjust the horizontal and vertical positions of the display screen 100 .
当然，在其他实施方式中，当识别到预设弹出信号后，冰箱可以先进行最高优先级别用户Y’的识别，当识别成功后，再控制显示屏100脱离冰箱内部其他限位结构的限制。Of course, in other implementations, when the preset pop-up signal is recognized, the refrigerator can first identify the user Y' with the highest priority level, and then control the display screen 100 to break away from other limiting structures inside the refrigerator after the identification is successful.
也就是说，本实施方式中各个信号的识别、匹配过程并没有明确的先后关系，可以根据实际情况而定。That is to say, the identification and matching process of each signal in this implementation manner does not have a clear sequence, and may be determined according to actual conditions.
在本实施方式中，当完成显示屏100水平方向及竖直方向的调节之后，显示屏100还是呈竖直摆放，即此时显示屏100的屏幕与冰箱的前表面为平行状态。为了使得显示屏100与用户位置更加匹配，此时还进行如下操作：In this embodiment, after the adjustment of the horizontal direction and the vertical direction of the display screen 100 is completed, the display screen 100 is still placed vertically, that is, the screen of the display screen 100 is parallel to the front surface of the refrigerator. In order to make the display screen 100 more match the user's position, the following operations are also performed at this time:
捕获用户影像；capture user images;
控制所述显示屏100转动以使得始终能捕获到所述用户影像。The rotation of the display screen 100 is controlled so that the image of the user can always be captured.

麦克风的数量及位置可以根据实际情况而定，不以上述说明为限。The number and positions of the microphones may be determined according to actual conditions, and are not limited to the above description.
显示屏100与冰箱之间通过旋转轴相连，只有侧部和底部具有旋转轴，顶部不存在旋转轴。The display screen 100 is connected to the refrigerator through a rotation shaft, only the side and the bottom have rotation shafts, and there is no rotation shaft at the top.
另外，可以根据实际需要，在显示屏100的背部与预埋盒相连位置设置连接轴，起到稳固和辅助旋转的作用。In addition, according to actual needs, a connecting shaft can be provided at the position where the back of the display screen 100 is connected to the pre-embedded box, so as to stabilize and assist rotation.
冰箱内部可预存有声源库B，例如，当冰箱为家用冰箱时，声源库B可以包括男主人、女主人、儿童等的声源信息。A sound source library B may be pre-stored inside the refrigerator. For example, when the refrigerator is a household refrigerator, the sound source library B may include sound source information of the hostess, hostess, and children.
但不以此为限，例如，当冰箱为公共场合的冰箱时，声源库B可以包括男性、女性、儿童等的声源信息。But it is not limited thereto. For example, when the refrigerator is a refrigerator in a public place, the sound source library B may include sound source information of men, women, children, and so on.
综上所述，本实施方式中可以预存有声源库B等信息，如此，当接收到声源A后，便可通过内部分析直接得到用户是成人还是儿童，从而控制显示屏100左右转动或向下转动，调节过程简单便捷，用户体验极佳。To sum up, in this embodiment, information such as the sound source library B can be pre-stored, so that when the sound source A is received, it can be directly obtained through internal analysis whether the user is an adult or a child, so as to control the display screen 100 to rotate left and right or to Turn down, the adjustment process is simple and convenient, and the user experience is excellent.
在本实施方式中，通过调整显示屏100的旋转角度，则可以控制显示屏100与用户的视线实现垂直，或者在一定范围，例如75-105度，用户阅读或者观看影片的时候，视觉效果更好，这个并不具体设定，可以根据实际需要设定。In this embodiment, by adjusting the rotation angle of the display screen 100, the display screen 100 can be controlled to be perpendicular to the user's line of sight, or within a certain range, such as 75-105 degrees, when the user reads or watches a movie, the visual effect is better. Well, this is not a specific setting, it can be set according to actual needs.
在本实施方式中，步骤“接收声源A，将所述声源A与预设的声源库B进行匹配，若所述声源A为成人声源，则控制所述显示屏100向左或向右旋转”具体包括：In this embodiment, the step "receive sound source A, match the sound source A with the preset sound source library B, if the sound source A is an adult sound source, control the display screen 100 to the left or rotate right" specifically includes:
第一麦克风101及第二麦克风102接收声源A，所述第一麦克风101及所述第二麦克风102分别位于所述显示屏100的左侧及右侧；The first microphone 101 and the second microphone 102 receive the sound source A, and the first microphone 101 and the second microphone 102 are respectively located on the left side and the right side of the display screen 100;
分别获取所述第一麦克风101的第一接收时间T1及所述第二麦克风102的第二接收时间T2；respectively acquiring a first receiving time T1 of the first microphone 101 and a second receiving time T2 of the second microphone 102;
判断所述第一接收时间T1是否小于所述第二接收时间T2，若是，则控制所述显示屏100向左旋转，若否，则控制所述显示屏100向右旋转。Judging whether the first receiving time T1 is shorter than the second receiving time T2, if yes, controlling the display screen 100 to rotate to the left, if not, controlling the display screen 100 to rotate to the right.
这里，结合图8，当第一接收时间T1小于第二接收时间T2时，即表明此时用户与第一麦克风101之间的第一距离S1小于用户与第二麦克风102之间的第二距离S2，判定此时用户位于冰箱的靠近第一麦克风101的一侧，即位于显示屏100的左侧。Here, referring to FIG. 8, when the first receiving time T1 is less than the second receiving time T2, it means that the first distance S1 between the user and the first microphone 101 is smaller than the second distance between the user and the second microphone 102 at this time. S2, it is determined that the user is located on the side of the refrigerator close to the first microphone 101 at this time, that is, on the left side of the display screen 100 .
显示屏100上还设有一摄像头103。A camera 103 is also provided on the display screen 100 .
此时，控制显示屏100的左侧的旋转轴不动，右侧的旋转轴脱离预埋盒，开启显示屏100上的摄像头103，顺时针转动所述显示屏100，直至摄像头103捕获到的用户影像位于摄像头103的中间位置。Now, control the left side of the display screen 100 to not move, the right side of the shaft to break away from the pre-embedded box, turn on the camera 103 on the display screen 100, and turn the display screen 100 clockwise until the camera 103 captures the The user image is located in the middle of the camera 103 .
当然，在其他实施方式中，显示屏100的左右旋转角度也可由第一接收时间T1或第二接收时间T2确定，即并不依赖于摄像头103。Certainly, in other implementation manners, the left-right rotation angle of the display screen 100 may also be determined by the first receiving time T1 or the second receiving time T2 , that is, it does not depend on the camera 103 .
另外，当判断声源A为儿童时，则控制显示屏100向下旋转。In addition, when it is judged that the sound source A is a child, the display screen 100 is controlled to rotate downward.
这里，可以将儿童的身高H预存在冰箱内，且假设显示屏100的底部与地面之间的距离为H’，显示屏100的上下边缘之间的间距为L。Here, the child's height H can be pre-stored in the refrigerator, and it is assumed that the distance between the bottom of the display screen 100 and the ground is H', and the distance between the upper and lower edges of the display screen 100 is L.
用户与显示屏100麦克风之间的较短距离S=T1*V声。The short distance S=T1*Vsound between the user and the display screen 100 microphone.
显示屏100以底部的旋转轴为中心，由上向下倾斜的角度为α，其满足公式：The display screen 100 is centered on the rotation axis at the bottom, and the tilt angle from top to bottom is α, which satisfies the formula:
可以理解，冰箱内也可预存有成人的身高，显示屏100左右旋转之前或或之后或旋转过程中可以根据预设的身高实现显示屏100的上下调节。It can be understood that the height of an adult can also be pre-stored in the refrigerator, and the display screen 100 can be adjusted up and down according to the preset height before or after the display screen 100 rotates left and right or during the rotation process.
在本实施方式中，步骤“第一麦克风101及第二麦克风102接收声源A，所述第一麦克风101及所述第二麦克风102分别位于所述显示屏100的左侧及右侧”之后还包括：In this embodiment, after the step "the first microphone 101 and the second microphone 102 receive the sound source A, the first microphone 101 and the second microphone 102 are respectively located on the left side and the right side of the display screen 100" Also includes:
判断所述声源A是否为预设弹出信号，若是，则进入下一步骤；若否，则所述第一麦克风101及所述第二麦克风102继续接收声源。Judging whether the sound source A is a preset pop-up signal, if yes, proceed to the next step; if not, the first microphone 101 and the second microphone 102 continue to receive the sound source.
这里，例如可以在冰箱内预设弹出信号，例如为语音信号“我要看电视”，当用户说出“我要看电视”这句话时，冰箱便默认识别到了预设弹出信号，此时，可以进行显示屏100的调节。Here, for example, a pop-up signal can be preset in the refrigerator, such as the voice signal "I want to watch TV". When the user says "I want to watch TV", the refrigerator recognizes the preset pop-up signal by default. , the display screen 100 can be adjusted.
需要说明的是，当识别到预设弹出信号后，冰箱可以先控制显示屏100脱离冰箱内部其他限位结构的限制，即此时显示屏100可以进行多方向的调节操作，而后再根据用户的识别进行显示屏100的旋转控制。It should be noted that when the preset pop-up signal is recognized, the refrigerator can first control the display screen 100 to break away from the restrictions of other limiting structures inside the refrigerator, that is, the display screen 100 can perform multi-directional adjustment operations at this time, and then adjust according to the user's Recognition performs rotation control of the display screen 100 .
当然，在其他实施方式中，当识别到预设弹出信号后，冰箱可以先进行用户的识别，当识别成功后，再控制显示屏100脱离冰箱内部其他限位结构的限制。Certainly, in other implementation manners, when the preset pop-up signal is recognized, the refrigerator may first perform user identification, and then control the display screen 100 to break away from other limiting structures inside the refrigerator after the identification is successful.
也就是说，本实施方式中各个信号的识别、匹配过程并没有明确的先后关系，可以根据实际情况而定。That is to say, the identification and matching process of each signal in this implementation manner does not have a clear sequence, and may be determined according to actual conditions.
在本实施方式中，为了使得显示屏100与用户位置更加匹配，此时还进行如下操作：In this embodiment, in order to make the display screen 100 more match the user's position, the following operations are also performed at this time:
捕获用户影像；capture user images;
控制所述显示屏100转动以使得始终能捕获到所述用户影像。The rotation of the display screen 100 is controlled so that the image of the user can always be captured.
具体的，参图8，此时显示屏100上还设有摄像头103，摄像头103用于捕捉用户影像，当用户移动时，摄像头103带动显示屏100一起转动，直至摄像头103识别到的用户影像位于摄像头的中间位置，如此，可以保证显示屏100实时正对用户，提高用户体验。Specifically, referring to FIG. 8 , at this time, the display screen 100 is also provided with a camera 103, which is used to capture user images. When the user moves, the camera 103 drives the display screen 100 to rotate together until the user image recognized by the camera 103 is located at The middle position of the camera, in this way, can ensure that the display screen 100 faces the user in real time, improving user experience.
本实施方式还设置有运动检测单元（未图示），其用于判断用户的运动幅度，若所述运动幅度大于运动阈值，则控制所述显示屏100转动以使得摄像头103始终能捕获到所述用户影像，若所述运动幅度不大于运动阈值，则所述显示屏100不转动。This embodiment is also provided with a motion detection unit (not shown), which is used to judge the range of motion of the user. If the range of motion is greater than the motion threshold, the display screen 100 is controlled to rotate so that the camera 103 can always capture all For the user image, if the motion range is not greater than the motion threshold, the display screen 100 does not rotate.
如此，可以避免显示屏100过于频繁的转动而导致显示屏100结构不稳定或是冰箱功耗高。In this way, too frequent rotation of the display screen 100 can be avoided, resulting in an unstable structure of the display screen 100 or high power consumption of the refrigerator.
这里，当判断用户为成人时，可以在启动左右旋转的同时便启动摄像头103，当判断用户位儿童时，可以在旋转角度α之后再开启摄像头103，但不以此为限。Here, when it is judged that the user is an adult, the camera 103 can be turned on while turning left and right. When it is judged that the user is a child, the camera 103 can be turned on after the rotation angle α, but not limited thereto.
在本实施方式中，还涉及显示屏100复位的过程，显示屏100的复位过程可以参考第一实施方式，在此不再赘述。In this embodiment, the process of resetting the display screen 100 is also involved. For the process of resetting the display screen 100, reference may be made to the first embodiment, which will not be repeated here.
需要说明的是，上述提到的显示屏100的调节、复位等操作也可加入用户的人工调节，使其更加符合用户需求。It should be noted that, the above-mentioned operations such as adjustment and reset of the display screen 100 can also be manually adjusted by the user to make it more in line with the needs of the user.
显示屏100相对于冰箱可根据用户指令，与摄像头103结合，根据用户实际高度调整显示屏100旋转轴的旋转运动，不论成人或儿童，都能有较好的用户体验，并能够实现实时跟踪用户位置来旋转显示屏100旋转角度，旋转机构之间存在阻尼连接，能够保证在运动或静止过程中不会发生显示屏100晃动，影响其稳定性及观影感受。Compared with the refrigerator, the display screen 100 can be combined with the camera 103 according to the user's instructions, and the rotation of the display screen 100 can be adjusted according to the actual height of the user. No matter adults or children, they can have a better user experience and can track users in real time. Position to rotate the display screen 100 rotation angle, there is a damping connection between the rotating mechanisms, which can ensure that the display screen 100 will not shake during motion or static, affecting its stability and viewing experience.

假设显示屏100于冰箱预埋盒内时的高度H为H0，H0为显示屏100中心距离地面的距离；第一麦克风101、第二麦克风102分别设置于冰箱的两侧，冰箱内预存有声源库B及预设弹出信号。Assume that the height H of the display screen 100 in the refrigerator pre-embedded box is H0 , and H0 is the distance from the center of the display screen 100 to the ground; the first microphone 101 and the second microphone 102 are respectively installed on both sides of the refrigerator, and the There are sound source bank B and preset pop-up signals.
通过预设算法来操控冰箱显示屏旋转角度的方法包括步骤：The method for controlling the rotation angle of the display screen of the refrigerator through a preset algorithm includes the steps of:
S1：第一麦克风101、第二麦克风102接收声源A，判断所述声源是否为预设弹出信号，若是，则进入S2，若否，则继续接收声源A；S1: the first microphone 101 and the second microphone 102 receive the sound source A, and judge whether the sound source is a preset pop-up signal, if so, go to S2, if not, continue to receive the sound source A;
S2：将所述声源A与声源库B进行匹配，若声源A为成人，则进入S3，若声源A为儿童，则进入S4；S2: Match the sound source A with the sound source library B, if the sound source A is an adult, go to S3, if the sound source A is a child, go to S4;
S3：显示屏100默认只进行左右旋转，进入S5；S3: The display screen 100 only rotates left and right by default, enter S5;
S4：显示屏100默认只进行向下旋转，进入S5；S4: The display screen 100 only rotates downward by default, and enters S5;
S5：判断第一麦克风101及第二麦克风102接收到声源A的第一接收时间T1及第二接收时间T2的大小，若T1<T2，则进入S6，若T1≥T2，则利用T2代替T1后进入S6；S5: Determine the size of the first receiving time T1 and the second receiving time T2 when the first microphone 101 and the second microphone 102 receive the sound source A, if T1<T2, go to S6, if T1≥T2, use T2 instead Enter S6 after T1;
S6：若为成人，则确认用户位于显示屏100的哪一侧，并控制显示屏100向左或向右旋转，若为儿童，则控制显示屏100转动角度α，进入S7；S6: If it is an adult, then confirm which side of the display screen 100 the user is on, and control the display screen 100 to rotate left or right; if it is a child, then control the display screen 100 to rotate by an angle α, and enter S7;
S7：开启摄像头103，旋转显示屏100，使得摄像头103捕获到的用户影像位于摄像头的中间位置，进入S8；S7: Turn on the camera 103, rotate the display screen 100, so that the user image captured by the camera 103 is located in the middle of the camera, and enter S8;
S8：摄像头103发现用户并保证用户位于摄像头103的中间位置，同时，控制显示屏100转动，如此，便实现了显示屏100的自动调节。S8: The camera 103 detects the user and ensures that the user is located in the middle of the camera 103, and at the same time controls the rotation of the display screen 100, thus realizing the automatic adjustment of the display screen 100.
