The convenience and portability of notebook computers allow users to have powerful computing power and word processing functions anytime and anywhere, and provide complete audio-visual multimedia functions.

请参考图1，图1为现有的一笔记本电脑系统10的示意图。一般而言，笔记本电脑系统10是由一上盖100及一底座102所组成，上盖100与底座102是由一转轴104相连结。上盖100可包含屏幕、照相机等，而底座102则包含键盘、触控板、电源开关、主机、扩充接口等。当要使用笔记本电脑系统10时，使用者需将主机的电源打开，调整上盖100中的屏幕显示角度至某一特定角度。为了节省电源，笔记本电脑系统10中设有一切换开关，用来根据上盖100开启的角度，切换屏幕的启闭、主机的操作模式等。例如，当使用者开启笔记本电脑系统10后而不需使用笔记本电脑系统10时，使用者可合上上盖100，使得上盖100与底座102间的角度小于一特定值，则笔记本电脑系统10会关闭屏幕，并操作于休眠模式。Please refer to FIG. 1 , which is a schematic diagram of a conventionalnotebook computer system 10 . Generally speaking, thenotebook computer system 10 is composed of atop cover 100 and abase 102 , and thetop cover 100 and thebase 102 are connected by arotating shaft 104 . Theupper cover 100 may include a screen, a camera, etc., while thebase 102 includes a keyboard, a touch pad, a power switch, a host, an expansion interface, and the like. When using thenotebook computer system 10 , the user needs to turn on the power of the host computer and adjust the display angle of the screen in theupper cover 100 to a specific angle. In order to save power, thenotebook computer system 10 is provided with a switching switch, which is used to switch the opening and closing of the screen, the operating mode of the host, etc. according to the opening angle of theupper cover 100 . For example, when the user turns on thenotebook computer system 10 and does not need to use thenotebook computer system 10, the user can close thetop cover 100 so that the angle between thetop cover 100 and thebase 102 is less than a certain value, then thenotebook computer system 10 will turn off the screen and operate in sleep mode.

通过调整上盖100与底座102间的角度，使用者可节省电源消耗，并适时切换笔记本电脑系统10的操作模式。因此，准确地检测上盖100与底座102间的角度就显得非常重要。在现有的技术中，检测上盖100开启角度的方法有许多种，其中之一是通过连结于转轴104的一机械式开关，亦即当转轴104的旋转角度小于一特定值时，即关闭屏幕及执行其它相关运作(如操作于休眠模式)。然而，机械式开关的组装较困难，且随着使用时间增加，可能产生机械疲乏或故障的情形，而导致可靠性降低。By adjusting the angle between thetop cover 100 and thebase 102 , the user can save power consumption and switch the operation mode of thenotebook computer system 10 timely. Therefore, it is very important to accurately detect the angle between theupper cover 100 and thebase 102 . In the prior art, there are many ways to detect the opening angle of theupper cover 100, one of which is through a mechanical switch connected to therotating shaft 104, that is, when the rotating angle of therotating shaft 104 is less than a certain value, it will be closed. screen and perform other related operations (such as operating in sleep mode). However, the assembly of the mechanical switch is difficult, and as the use time increases, mechanical fatigue or failure may occur, resulting in reduced reliability.

另一种现有的方式是通过磁极检测方式，如使用霍尔传感器(Hall Sensor)或磁阻式传感器(Magnetic Reluctance Sensor)，检测上盖100与底座102间的距离，以判断上盖100与底座102间的角度。以霍尔传感器为例，霍尔传感器可感应磁极、磁力等，因此，只要在上盖100与底座102中，分别增加一个磁铁及一霍尔传感器，即可通过霍尔传感器检测磁铁的磁力，而判断出上盖100与底座102间的距离，进而估算上盖100与底座102间的角度。然而，通过磁极检测方式，在设置磁铁及传感器时，必须考虑传感器的灵敏度并搭配磁铁的磁通量，以符合设计需求。另外，若使用磁阻式传感器时，由于磁阻式传感器的灵敏度高，造成其线性范围低，使得设计上的困难度提高。Another existing method is to detect the distance between theupper cover 100 and thebase 102 by using a Hall Sensor or a Magnetic Reluctance Sensor to determine the distance between theupper cover 100 and thebase 102. The angle between thebases 102. Taking the Hall sensor as an example, the Hall sensor can sense magnetic poles, magnetic force, etc. Therefore, as long as a magnet and a Hall sensor are respectively added to theupper cover 100 and thebase 102, the magnetic force of the magnet can be detected by the Hall sensor. Then the distance between theupper cover 100 and thebase 102 is determined, and then the angle between theupper cover 100 and thebase 102 is estimated. However, with the magnetic pole detection method, when setting the magnet and the sensor, the sensitivity of the sensor and the magnetic flux of the magnet must be considered to meet the design requirements. In addition, if a magnetoresistive sensor is used, the linear range of the magnetoresistive sensor is low due to its high sensitivity, which increases the difficulty in design.

具体实施方式Detailed ways

为了避免机械式开关及磁极检测方式的缺点，本发明是使用重力加速度传感器(Gravity Acceleration Sensor，简称G-sensor)，取得对应于铅垂线的角度(即绝对角度)，进而判断笔记本电脑的上盖是否开启。如本领域具通常知识者所知，在重力场强度大于1G(G表示海平面高度的重力场强度)的环境，重力加速度传感器可用于检测加速度；而在重力场强度小于1G的环境，重力加速度传感器可根据所在位置的绝对角度，产生不同大小的电压、电流等电气或电子信号，因而可用来检测角度，其所对应的角度与输出电压关系如图2所示。由图2可知，随着所在位置的绝对角度的不同，重力加速度传感器所输出的电压值亦随之改变。本发明即是利用此特性，准确判断一可携式电子装置的上盖是否开启，并据以切换可携式电子装置的操作模式，请见以下说明。特别注意的是，以下是以笔记本电脑系统为例说明本发明的实施方式，凡具有上盖及底座的可携式电子装置，如个人数字助理、智能型移动电话等，皆适用于本发明。此外，本发明所使用的重力加速度传感器所输出的信号可以是任何型式的电气或电子信号，如电压、电流等。In order to avoid the shortcomings of mechanical switches and magnetic pole detection methods, the present invention uses a gravity acceleration sensor (Gravity Acceleration Sensor, referred to as G-sensor) to obtain the angle corresponding to the plumb line (that is, the absolute angle), and then determine the upper and lower positions of the notebook computer. Is the cover open. As known to those skilled in the art, in an environment where the gravitational field strength is greater than 1G (G represents the gravitational field strength at sea level), the gravitational acceleration sensor can be used to detect acceleration; and in an environment where the gravitational field strength is less than 1G, the gravitational acceleration The sensor can generate electrical or electronic signals such as voltages and currents of different sizes according to the absolute angle of the location, so it can be used to detect the angle. The relationship between the corresponding angle and the output voltage is shown in Figure 2. It can be seen from FIG. 2 that, with the difference of the absolute angle of the position, the voltage value output by the acceleration of gravity sensor also changes accordingly. The present invention utilizes this feature to accurately determine whether the upper cover of a portable electronic device is opened, and switch the operation mode of the portable electronic device accordingly. Please refer to the following description. It should be noted that the following uses a notebook computer system as an example to illustrate the implementation of the present invention. Any portable electronic device with a cover and a base, such as a personal digital assistant, a smart mobile phone, etc., is applicable to the present invention. In addition, the signal output by the gravitational acceleration sensor used in the present invention may be any type of electrical or electronic signal, such as voltage, current and so on.

进一步解释铅垂线、水平线及地表的关系，请参考图11，水平线是指在地表某点上沿水平方向的虚拟直线，而铅垂线则指在该点上垂直于水平线的虚拟直线，本发明所称的“绝对角度”是指相对于铅垂线的角度，例如角度x表示绝对角度为-45度，而角度y表示绝对角度为75度。以此类推，若一笔记本电脑的底座置于水平面上且上盖合盖时，则上盖的绝对角度约为-90度。因此，通过检测上盖的绝对角度，可得知上盖是否开启。To further explain the relationship between the plumb line, the horizontal line and the ground surface, please refer to Figure 11. The horizontal line refers to a virtual straight line along the horizontal direction at a certain point on the ground surface, and the plumb line refers to a virtual straight line perpendicular to the horizontal line at this point. The "absolute angle" referred to in the invention refers to the angle relative to the plumb line, for example, the angle x indicates that the absolute angle is -45 degrees, and the angle y indicates that the absolute angle is 75 degrees. By analogy, if the base of a notebook computer is placed on a horizontal plane and the top cover is closed, the absolute angle of the top cover is about -90 degrees. Therefore, by detecting the absolute angle of the upper cover, it can be known whether the upper cover is opened.

请参考图3，图3为本发明实施例一笔记本电脑系统30的示意图。笔记本电脑系统30可适时切换操作模式，用以节省电源消耗，其包含有一上盖300、一底座302及一操作模式控制装置40。上盖300包含屏幕、照相机等，而底座302则包含键盘、触控板、电源开关、主机、扩充接口等。请继续参考图4，图4为操作模式控制装置40的功能方块图。操作模式控制装置40耦接于笔记本电脑系统30的一主机404，其包含有一重力加速度传感器400及一控制单元402。重力加速度传感器400设于笔记本电脑系统30的上盖300上，用来检测上盖300对应于铅垂线的角度，并将检测结果(如电压、电流等电气或电子信号)输出至控制单元402。控制单元402较佳地设于笔记本电脑系统30的一键盘控制器中，用以根据重力加速度传感器400所得的检测结果，控制笔记本电脑系统30的操作模式。Please refer to FIG. 3 , which is a schematic diagram of anotebook computer system 30 according to an embodiment of the present invention. Thenotebook computer system 30 can switch operation modes in good time to save power consumption, and includes atop cover 300 , abase 302 and an operationmode control device 40 . Theupper cover 300 includes a screen, a camera, etc., and thebase 302 includes a keyboard, a touch pad, a power switch, a host, an expansion interface, and the like. Please continue to refer to FIG. 4 , which is a functional block diagram of the operationmode control device 40 . The operationmode control device 40 is coupled to ahost 404 of thenotebook computer system 30 , and includes agravity acceleration sensor 400 and acontrol unit 402 . The acceleration ofgravity sensor 400 is arranged on theupper cover 300 of thenotebook computer system 30, and is used to detect the angle of theupper cover 300 corresponding to the plumb line, and output the detection result (such as electrical or electronic signals such as voltage and current) to thecontrol unit 402 . Thecontrol unit 402 is preferably disposed in a keyboard controller of thenotebook computer system 30 to control the operation mode of thenotebook computer system 30 according to the detection result obtained by the acceleration ofgravity sensor 400 .

因此，通过操作模式控制装置40，笔记本电脑系统30可借助重力加速度传感器400测得上盖300对应于铅垂线的角度，以判断上盖300是否开启。特别注意的是，利用重力加速度传感器400判断上盖300是否开启的方式不限于特定程序或步骤，本领域具通常知识者当可设计符合所需的判断流程。举例来说，请参考图5，图5为本发明实施例一操作模式控制流程50的示意图。操作模式控制流程50用于操作模式控制装置40中，用以控制笔记本电脑系统30的操作模式，其包含以下步骤：Therefore, through the operationmode control device 40 , thenotebook computer system 30 can measure the angle of theupper cover 300 corresponding to the vertical line through the acceleration ofgravity sensor 400 to determine whether theupper cover 300 is opened. It should be noted that the way of using the acceleration ofgravity sensor 400 to determine whether theupper cover 300 is opened is not limited to specific procedures or steps, and those skilled in the art can design a required determination process. For example, please refer to FIG. 5 , which is a schematic diagram of an operationmode control process 50 according to an embodiment of the present invention. The operationmode control process 50 is used in the operationmode control device 40 to control the operation mode of thenotebook computer system 30, which includes the following steps:

步骤500：开始。Step 500: start.

步骤502：通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A。Step 502 : Detect an angle A of theupper cover 300 relative to the vertical line through the acceleration ofgravity sensor 400 .

步骤504：由控制单元402比较角度A是否小于一合盖角度A_def。若是，进行步骤506；若否，则回到步骤502。Step 504: Thecontrol unit 402 compares whether the angle A is smaller than a closing angle A_def. If yes, go to step 506; if not, go back tostep 502.

步骤506：判断上盖300已合盖。Step 506: Determine that theupper cover 300 has been closed.

步骤508：将笔记本电脑系统30操作于省电模式。Step 508: Operate thenotebook computer system 30 in the power saving mode.

因此，通过操作模式控制流程50，当重力加速度传感器400所测得的角度A小于合盖角度A_def时，控制单元402可判断上盖300已合盖，进而将笔记本电脑系统30操作于省电模式。在此情形下，只需将重力加速度传感器400固定于上盖300上，则重力加速度传感器400可随着上盖300不同的开启角度，产生不同大小的电压、电流等电气或电子信号(如图2所示)。如此一来，不需担心机械疲乏或故障的情形，且重力加速度传感器400固定于上盖300的位置不需特别考虑，因而可降低设计上的困难度。Therefore, through the operationmode control process 50, when the angle A measured by the acceleration ofgravity sensor 400 is smaller than the cover closing angle A_def, thecontrol unit 402 can determine that theupper cover 300 has been closed, and then operate thenotebook computer system 30 in the power saving mode . In this case, it is only necessary to fix the acceleration ofgravity sensor 400 on theupper cover 300, and the acceleration ofgravity sensor 400 can generate electrical or electronic signals such as voltages and currents of different sizes according to different opening angles of the upper cover 300 (as shown in FIG. 2). In this way, there is no need to worry about mechanical fatigue or failure, and the position where the acceleration ofgravity sensor 400 is fixed on theupper cover 300 does not need special consideration, thus reducing the difficulty in design.

借助操作模式控制流程50，操作模式控制装置40可准确判断上盖300的绝对角度，并据以控制笔记本电脑系统30的操作模式。为避免使用者在使用笔记本电脑系统30的过程中，搬动或移动笔记本电脑系统30使得笔记本电脑系统30不是静止的水平面上不动，而造成误判而进入省电模式，本发明另提供一控制方式。请参考图6，图6为本发明实施例一操作模式控制流程60的示意图。操作模式控制流程60用于操作模式控制装置40中，用以控制笔记本电脑系统30的操作模式，其包含以下步骤：With the operationmode control process 50 , the operationmode control device 40 can accurately determine the absolute angle of theupper cover 300 and control the operation mode of thenotebook computer system 30 accordingly. In order to prevent the user from moving or moving thenotebook computer system 30 in the process of using thenotebook computer system 30 so that thenotebook computer system 30 is not stationary on a horizontal plane, causing a misjudgment and entering the power saving mode, the present invention further provides a control method. Please refer to FIG. 6 , which is a schematic diagram of an operationmode control process 60 according to an embodiment of the present invention. The operationmode control process 60 is used in the operationmode control device 40 to control the operation mode of thenotebook computer system 30, which includes the following steps:

步骤600：开始。Step 600: start.

步骤602：通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A1。Step 602 : Detect an angle A1 of theupper cover 300 relative to the vertical line through the acceleration ofgravity sensor 400 .

步骤604：延迟时间t。Step 604: Delay time t.

步骤606：通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A2。Step 606 : Detect an angle A2 of theupper cover 300 relative to the vertical line through the acceleration ofgravity sensor 400 .

步骤608：由控制单元402比较角度A1与角度A2是否相等。若角度A1与角度A2相等，进行步骤610；若角度A1与角度A2不相等，则回到步骤602。Step 608: Thecontrol unit 402 compares whether the angle A1 is equal to the angle A2. If the angle A1 is equal to the angle A2, go to step 610; if the angle A1 is not equal to the angle A2, go back to step 602.

步骤610：由控制单元402比较角度A2是否小于一合盖角度A3。若是，进行步骤612；若否，则回到步骤602。Step 610: Thecontrol unit 402 compares whether the angle A2 is smaller than a closing angle A3. If yes, go to step 612; if not, go back to step 602.

步骤612：判断上盖300已合盖。Step 612: Determine that theupper cover 300 has been closed.

步骤614：将笔记本电脑系统30操作于省电模式。Step 614: Operate thenotebook computer system 30 in the power saving mode.

因此，通过操作模式控制流程60，重力加速度传感器400先测得的角度A1，延迟时间t后，再测得的角度A2。接着，若角度A1与角度A2相等，则控制单元402比较角度A1是否小于合盖角度A3，并于角度A1小于合盖角度A3时，判断上盖300已合盖，进而将笔记本电脑系统30操作于省电模式。简单来说，在操作模式控制流程60，角度A1、A2皆为重力加速度传感器400所测得的绝对角度(即相对于铅垂线的角度)，而合盖角度A3则为系统预设的临限角度。亦即，当角度A2小于合盖角度A3时，表示上盖300已合盖；相反地，当角度A2大于合盖角度A3时，则表示上盖300已开启。如此一来，可据以决定笔记本电脑系统30的操作模式。Therefore, through the operationmode control process 60, the acceleration ofgravity sensor 400 first measures the angle A1, and then measures the angle A2 after a delay of time t. Next, if the angle A1 is equal to the angle A2, thecontrol unit 402 compares whether the angle A1 is smaller than the closing angle A3, and when the angle A1 is smaller than the closing angle A3, judges that theupper cover 300 has been closed, and then operates thenotebook computer system 30 in power saving mode. To put it simply, in the operationmode control process 60, the angles A1 and A2 are the absolute angles measured by the acceleration of gravity sensor 400 (that is, the angle relative to the plumb line), and the lid closing angle A3 is the system preset temporary angle. limited angle. That is, when the angle A2 is smaller than the closing angle A3, it means that theupper cover 300 has been closed; on the contrary, when the angle A2 is greater than the closing angle A3, it means that theupper cover 300 has been opened. In this way, the operation mode of thenotebook computer system 30 can be determined accordingly.

比较操作模式控制流程60与操作模式控制流程50可知，操作模式控制流程60是在时间t内，检测上盖角度两次。当两次角度相等时，可判断笔记本电脑系统30未被搬动或移动，才继续判断上盖300是否已达合盖角度A3。相反的，若两次角度不相等，表示笔记本电脑系统30被搬动或移动，则不判断上盖300是否已达合盖角度A3。如此一来，通过操作模式控制流程60，操作模式控制装置40可准确判断上盖300的角度，并可避免搬动笔记本电脑系统30所造成的误判。Comparing the operationmode control process 60 with the operationmode control process 50, it can be seen that the operationmode control process 60 detects the upper cover angle twice within the time t. When the two angles are equal, it can be determined that thenotebook computer system 30 has not been moved or moved, and then continue to determine whether theupper cover 300 has reached the closing angle A3. On the contrary, if the two angles are not equal, it means that thenotebook computer system 30 is carried or moved, and it is not judged whether theupper cover 300 has reached the closing angle A3. In this way, through the operationmode control process 60 , the operationmode control device 40 can accurately determine the angle of theupper cover 300 and avoid misjudgment caused by moving thenotebook computer system 30 .

操作模式控制流程60可避免搬动笔记本电脑系统30所造成的误判，但若使用者躺着或以仰望方式使用笔记本电脑系统30，例如图12所示的情形，造成上盖300相对于铅垂线的角度小于合盖角度，则操作模式控制流程60仍可能发生误判的问题。因此，本发明另提供一控制方式。请参考图7，图7为本发明实施例一操作模式控制流程70的示意图。操作模式控制流程70用于操作模式控制装置40中，用以控制笔记本电脑系统30的操作模式，其包含以下步骤：The operationmode control process 60 can avoid misjudgment caused by moving thenotebook computer system 30, but if the user uses thenotebook computer system 30 lying down or looking up, such as the situation shown in FIG. If the angle of the vertical line is smaller than the lid closing angle, misjudgment may still occur in the operationmode control process 60 . Therefore, the present invention further provides a control method. Please refer to FIG. 7 , which is a schematic diagram of an operationmode control process 70 according to an embodiment of the present invention. The operationmode control process 70 is used in the operationmode control device 40 to control the operation mode of thenotebook computer system 30, which includes the following steps:

步骤700：开始。Step 700: start.

步骤702：通过重力加速度传感器400检测上盖300相对于铅垂线的一初始角度A1。Step 702 : Detect an initial angle A1 of theupper cover 300 relative to the vertical line through the acceleration ofgravity sensor 400 .

步骤704：通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A2。Step 704 : Detect an angle A2 of theupper cover 300 relative to the vertical line through the acceleration ofgravity sensor 400 .

步骤706：延迟时间t。Step 706: Delay time t.

步骤708：通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A3。Step 708 : Detect an angle A3 of theupper cover 300 relative to the vertical line through the acceleration ofgravity sensor 400 .

步骤710：由控制单元402比较角度A2与角度A3是否相等。若角度A2与角度A3相等，进行步骤712；若角度A2与角度A3不相等，则回到步骤704。Step 710: Thecontrol unit 402 compares whether the angle A2 is equal to the angle A3. If the angle A2 is equal to the angle A3, go to step 712; if the angle A2 is not equal to the angle A3, go back tostep 704.

步骤712：计算初始角度A1与角度A2的一角度差D1。Step 712: Calculate an angle difference D1 between the initial angle A1 and the angle A2.

步骤714：由控制单元402比较角度差D1是否大于一合盖角度差D2。若是，进行步骤716；若否，则回到步骤704。Step 714: Thecontrol unit 402 compares whether the angle difference D1 is greater than a closing angle difference D2. If yes, go to step 716; if not, go back tostep 704.

步骤716：判断上盖300已合盖。Step 716: Determine that theupper cover 300 has been closed.

步骤718：将笔记本电脑系统30操作于省电模式。Step 718: Operate thenotebook computer system 30 in the power saving mode.

因此，通过操作模式控制流程70，重力加速度传感器400先测得的初始角度A1，再于时间t内，测得的角度A2、A3。接着，若角度A2与角度A3相等，则控制单元402比较初始角度A1与角度A2的角度差D1是否大于合盖角度差D2，并于角度差D1大于合盖角度差D2时，判断上盖300已合盖，进而将笔记本电脑系统30操作于省电模式。简单来说，在操作模式控制流程70，初始角度A1为重力加速度传感器400一开始(如笔记本电脑系统30刚开机时，或刚启动操作模式控制装置40时)所测得的绝对角度，角度A2、A3则分别为重力加速度传感器400于不同时间(延迟时间t)所测得的绝对角度，角度差D1为初始角度A1与角度A2的角度差，而合盖角度差D2则为系统预设的临限角度差。亦即，当角度差D1大于合盖角度差D2时，表示上盖300已合盖；相反地，当角度差D1小于合盖角度差D2时，则表示上盖300已开启。如此一来，可据以决定笔记本电脑系统30的操作模式。Therefore, through the operationmode control process 70 , the acceleration ofgravity sensor 400 first measures the initial angle A1 , and then measures the angles A2 and A3 within the time t. Next, if the angle A2 is equal to the angle A3, thecontrol unit 402 compares whether the angle difference D1 between the initial angle A1 and the angle A2 is greater than the closing angle difference D2, and when the angle difference D1 is greater than the closing angle difference D2, determines whether theupper cover 300 is closed. The lid is closed, and thenotebook computer system 30 is operated in the power saving mode. In short, in the operationmode control process 70, the initial angle A1 is the absolute angle measured by the acceleration ofgravity sensor 400 at the beginning (such as when thenotebook computer system 30 is just turned on, or when the operationmode control device 40 is just started), and the angle A2 is , A3 are the absolute angles measured by thegravity acceleration sensor 400 at different times (delay time t), the angle difference D1 is the angle difference between the initial angle A1 and the angle A2, and the closing angle difference D2 is the system preset Threshold angle difference. That is, when the angle difference D1 is greater than the closing angle difference D2, it indicates that theupper cover 300 has been closed; on the contrary, when the angle difference D1 is smaller than the closing angle difference D2, it indicates that theupper cover 300 has been opened. In this way, the operation mode of thenotebook computer system 30 can be determined accordingly.

比较操作模式控制流程70与操作模式控制流程60可知，操作模式控制流程70是先纪录初始角度A1，然后在时间t内，检测上盖角度两次。当两次角度相等时，可判断笔记本电脑系统30未被搬动或移动，才继续判断上盖300是否已合盖。相反的，若两次角度不相等，表示笔记本电脑系统30被搬动或移动，则不判断上盖300是否已合盖。如此一来，通过操作模式控制流程70，操作模式控制装置40可准确判断上盖300的角度，并可避免搬动笔记本电脑系统30所造成的误判。同时，若使用者一开始即以躺着或仰望方式使用笔记本电脑系统30，操作模式控制流程70仍可借助比较角度差D1与合盖角度差D2，而判断上盖300是否以合盖。Comparing the operation mode control flow 70 with the operationmode control flow 60, it can be seen that the operation mode control flow 70 first records the initial angle A1, and then detects the upper cover angle twice within the time t. When the two angles are equal, it can be judged that thenotebook computer system 30 has not been moved or moved, and then continue to judge whether theupper cover 300 has been closed. On the contrary, if the two angles are not equal, it means that thenotebook computer system 30 is carried or moved, and it is not determined whether theupper cover 300 is closed. In this way, through the operationmode control process 70 , the operationmode control device 40 can accurately determine the angle of theupper cover 300 and avoid misjudgment caused by moving thenotebook computer system 30 . Meanwhile, if the user uses thenotebook computer system 30 lying down or looking up at the beginning, the operationmode control process 70 can still judge whether theupper cover 300 is closed by comparing the angle difference D1 and the cover closing angle difference D2.

在图3所示的笔记本电脑系统30中，操作模式控制装置40仅使用一重力加速度传感器，即可判断上盖300的开启角度。除此之外，为提升判断准确性本发明另可使用二个以上的重力加速度传感器，判断上盖的开启角度。请参考图8，图8为本发明实施例一笔记本电脑系统80的示意图。笔记本电脑系统80可适时切换操作模式，用以节省电源消耗，其包含有一上盖800、一底座802及一操作模式控制装置90。上盖800包含屏幕、照相机等，而底座802则包含键盘、触控板、电源开关、主机、扩充接口等。请继续参考图9，图9为操作模式控制装置90的功能方块图。操作模式控制装置90耦接于笔记本电脑系统80的一主机906，其包含有一第一重力加速度传感器900、一第二重力加速度传感器902及一控制单元904。第一重力加速度传感器900设于笔记本电脑系统80的上盖800上，用来检测上盖800对应于铅垂线的角度，并将检测结果(如电压、电流等电气或电子信号)输出至控制单元904；而第二重力加速度传感器902则设于笔记本电脑系统80的底座802上，用来检测底座802对应于铅垂线的角度，并将检测结果(如电压、电流等电气或电子信号)输出至控制单元904。控制单元904较佳地设于笔记本电脑系统80的一键盘控制器中，用来根据第一重力加速度传感器900及第二重力加速度传感器902所得的检测结果，控制笔记本电脑系统80的操作模式。In thenotebook computer system 30 shown in FIG. 3 , the operationmode control device 40 can determine the opening angle of theupper cover 300 by only using a gravity acceleration sensor. In addition, in order to improve the judgment accuracy, the present invention can use more than two gravitational acceleration sensors to judge the opening angle of the upper cover. Please refer to FIG. 8 , which is a schematic diagram of anotebook computer system 80 according to an embodiment of the present invention. Thenotebook computer system 80 can switch operation modes in good time to save power consumption, and includes a top cover 800 , a base 802 and an operationmode control device 90 . The upper cover 800 includes a screen, a camera, etc., while the base 802 includes a keyboard, a touch pad, a power switch, a host, an expansion interface, and the like. Please continue to refer to FIG. 9 , which is a functional block diagram of the operationmode control device 90 . The operationmode control device 90 is coupled to ahost 906 of thenotebook computer system 80 , and includes a first acceleration ofgravity sensor 900 , a second acceleration ofgravity sensor 902 and acontrol unit 904 . The first acceleration ofgravity sensor 900 is arranged on the upper cover 800 of thenotebook computer system 80, and is used to detect the angle of the upper cover 800 corresponding to the plumb line, and outputs the detection results (such as electrical or electronic signals such as voltage and current) to the controller.Unit 904; and the second acceleration ofgravity sensor 902 is arranged on the base 802 of thenotebook computer system 80, and is used to detect the angle of the base 802 corresponding to the plumb line, and the detection results (such as electrical or electronic signals such as voltage and current) output to thecontrol unit 904. Thecontrol unit 904 is preferably disposed in a keyboard controller of thenotebook computer system 80 , and is used to control the operation mode of thenotebook computer system 80 according to the detection results obtained by the firstgravity acceleration sensor 900 and the secondgravity acceleration sensor 902 .

因此，通过操作模式控制装置90，笔记本电脑系统80可借助第一重力加速度传感器900测得上盖800对应于铅垂线的角度，并通过第二重力加速度传感器902测得底座802对应于铅垂线的角度，进而判断上盖800是否开启。特别注意的是，利用第一重力加速度传感器900及第二重力加速度传感器902判断上盖800是否开启的方式不限于特定程序或步骤，本领域具通常知识者当可设计符合所需的判断流程。举例来说，请参考图10，图10为本发明实施例一操作模式控制流程110的示意图。操作模式控制流程110用于操作模式控制装置90中，用以控制笔记本电脑系统80的操作模式，其包含以下步骤：Therefore, through the operationmode control device 90, thenotebook computer system 80 can measure the angle of the upper cover 800 corresponding to the vertical line through the first acceleration ofgravity sensor 900, and measure the angle of the base 802 corresponding to the vertical line through the second acceleration ofgravity sensor 902. The angle of the line, and then determine whether the upper cover 800 is open. It should be noted that the method of using the first acceleration-of-gravity sensor 900 and the second acceleration-of-gravity sensor 902 to determine whether the upper cover 800 is opened is not limited to specific procedures or steps, and those skilled in the art can design a judging process that meets the requirements. For example, please refer to FIG. 10 , which is a schematic diagram of an operationmode control process 110 according to an embodiment of the present invention. The operationmode control process 110 is used in the operationmode control device 90 to control the operation mode of thenotebook computer system 80, which includes the following steps:

步骤112：开始。Step 112: Start.

步骤114：通过第一重力加速度传感器900检测上盖800相对于铅垂线的一角度G1。Step 114: Detect an angle G1 of the upper cover 800 relative to the vertical line through the firstgravitational acceleration sensor 900 .

步骤116：通过第二重力加速度传感器902检测底座802相对于铅垂线的一角度G2Step 116: Detect an angle G2 of the base 802 relative to the plumb line through the secondgravitational acceleration sensor 902

步骤118：由控制单元904计算角度G1与角度G2的角度差D1。Step 118 : Thecontrol unit 904 calculates an angle difference D1 between the angle G1 and the angle G2 .

步骤120：由控制单元904比较角度差D1是否大于一合盖角度差D2。若是，进行步骤122；若否，则回到步骤114及116。Step 120: Thecontrol unit 904 compares whether the angle difference D1 is greater than a closing angle difference D2. If yes, go to step 122 ; if not, go back tosteps 114 and 116 .

步骤122：判断上盖800已合盖。Step 122: Determine that the upper cover 800 has been closed.

步骤124：将笔记本电脑系统80操作于省电模式。Step 124: Operate thenotebook computer system 80 in a power saving mode.

因此，通过操作模式控制流程110，第一重力加速度传感器900及第二重力加速度传感器902分别测得的角度G1、G2后，控制单元904计算角度G1与角度G2的角度差D1。接着，控制单元904比较角度差D1是否大于合盖角度差D2，并于角度差D1大于合盖角度差D2时，判断上盖800已合盖，进而将笔记本电脑系统80操作于省电模式。简单来说，在操作模式控制流程110，角度G1、G2分别为第一重力加速度传感器900及第二重力加速度传感器902所测得的绝对角度(即相对于铅垂线的角度)，两者的差为角度差D1，而合盖角度差D2则为系统预设的临限角度差。亦即，当角度差D1大于合盖角度差D2时，表示上盖800已合盖；相反地，当角度差D1小于合盖角度差D2时，则表示上盖800已开启。如此一来，可据以决定笔记本电脑系统80的操作模式。Therefore, through the operationmode control process 110 , after the firstgravitational acceleration sensor 900 and the secondgravitational acceleration sensor 902 respectively measure the angles G1 and G2 , thecontrol unit 904 calculates the angle difference D1 between the angle G1 and the angle G2 . Next, thecontrol unit 904 compares whether the angle difference D1 is greater than the closing angle difference D2, and when the angle difference D1 is greater than the closing angle difference D2, determines that the upper cover 800 is closed, and then operates thenotebook computer system 80 in the power saving mode. To put it simply, in the operationmode control process 110, the angles G1 and G2 are the absolute angles measured by the first acceleration-of-gravity sensor 900 and the second acceleration-of-gravity sensor 902 (that is, the angle relative to the vertical line), and the angles G1 and G2 of the two are respectively The difference is the angle difference D1, and the cover closing angle difference D2 is the threshold angle difference preset by the system. That is, when the angle difference D1 is greater than the closing angle difference D2, it indicates that the upper cover 800 has been closed; on the contrary, when the angle difference D1 is smaller than the closing angle difference D2, it indicates that the upper cover 800 has been opened. In this way, the operation mode of thenotebook computer system 80 can be determined accordingly.

因此，借助操作模式控制流程70，即使使用者以躺着或仰望方式使用笔记本电脑系统80，或是在使用的过程中，搬动或移动笔记本电脑系统80，操作模式控制装置90仍可借助比较角度差D1与合盖角度差D2，而判断上盖800是否以合盖。Therefore, with the help of the operationmode control process 70, even if the user uses thenotebook computer system 80 lying down or looking up, or carries or moves thenotebook computer system 80 during use, the operationmode control device 90 can still use the comparison The angle difference D1 and the closing angle difference D2 are used to determine whether the upper cover 800 is closed.

综上所述，本发明是借助重力加速度传感器判断笔记本电脑系统的上盖是否开启，并据以切换操作模式，因而可避免机械疲乏或故障的问题，并可大幅降低设计上的困难度。To sum up, the present invention judges whether the top cover of the notebook computer system is open by means of the acceleration of gravity sensor, and switches the operation mode accordingly, thereby avoiding the problems of mechanical fatigue or failure, and greatly reducing the difficulty in design.
