技术领域technical field
本发明实施例涉及通信领域，尤其涉及一种恢复惯性传感器工作状态的方法及移动终端。The embodiments of the present invention relate to the field of communications, and in particular to a method for restoring the working state of an inertial sensor and a mobile terminal.
背景技术Background technique
随着智能移动终端的普及和广泛的应用，人们对移动终端智能化的体验要求也越来越高。基于MEMS(Micro-Electro-Mechanical Systems，微机电系统)的惯性传感器，如加速度传感器、陀螺仪、加速度和陀螺仪二合一传感器等已成为移动终端的基本配置需求。With the popularization and wide application of smart mobile terminals, people's requirements for intelligent experience of mobile terminals are also getting higher and higher. Inertial sensors based on MEMS (Micro-Electro-Mechanical Systems, Micro-Electro-Mechanical Systems), such as acceleration sensors, gyroscopes, acceleration and gyroscope combo sensors, etc. have become the basic configuration requirements of mobile terminals.
基于MEMS的惯性传感器通常有两部分构成：一部分是数字部分，用于接收、处理、反馈MEMS结构的信号变化；另一部分是机械硅结构部分，用于感测移动终端的惯性移动。该机械硅胶结构部分通常采用双面光刻技术、深层和高深宽腐蚀、各向异性腐蚀、自停止技术、硅硅直接键合等制成，在移动终端生产制造和用户使用中对高机械应力，温度剧变、疲劳使用都较敏感。MEMS-based inertial sensors usually consist of two parts: one part is a digital part, which is used to receive, process, and feed back signal changes of the MEMS structure; the other part is a mechanical silicon structure part, which is used to sense the inertial movement of the mobile terminal. The mechanical silicone structure part is usually made by double-sided photolithography technology, deep and high depth and width etching, anisotropic etching, self-stop technology, silicon-silicon direct bonding, etc. , temperature drastic changes, fatigue use are more sensitive.
在移动终端使用的过程中可能会出现由于惯性传感器失效而引起的工作异常的现象，但是用户本身无法解决这个问题，从而影响了用户对移动终端的使用体验。例如，当移动终端跌落时，惯性传感器受应力、静电力等因素的影响，将会导致质量块之间、质量块和硅基体之间发生黏附。当产生这种失效时，将会导致一些基于惯性传感器的应用无法正常工作，如屏幕无法旋转，照片无法横竖切换，游戏控制失效等，从而影响了用户对移动终端的使用体验。During the use of the mobile terminal, abnormal work may occur due to failure of the inertial sensor, but the user cannot solve this problem, thereby affecting the user's experience of using the mobile terminal. For example, when the mobile terminal falls, the inertial sensor is affected by factors such as stress and electrostatic force, which will cause adhesion between the mass blocks, and between the mass blocks and the silicon substrate. When this kind of failure occurs, some applications based on inertial sensors will not work normally, such as the screen cannot be rotated, the photos cannot be switched horizontally and vertically, and the game control will become invalid, thereby affecting the user experience of the mobile terminal.

Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
第一实施例first embodiment
如图1所示，本发明第一实施例的恢复惯性传感器工作状态的方法，应用于移动终端，包括：As shown in Figure 1, the method for restoring the working state of an inertial sensor according to the first embodiment of the present invention is applied to a mobile terminal, including:
步骤101、获取移动终端中的惯性传感器的状态判别参数。Step 101, acquire state discrimination parameters of inertial sensors in the mobile terminal.
在移动终端中的可以设置的惯性传感器包括但不限于为加速度传感器、陀螺仪、加速度和陀螺仪二合一传感器等。因此，不同类型的惯性传感器，在此获取的状态判别参数不同。The inertial sensors that can be set in the mobile terminal include but are not limited to acceleration sensors, gyroscopes, acceleration and gyroscope two-in-one sensors, and the like. Therefore, different types of inertial sensors have different state discrimination parameters obtained here.
当惯性传感器为加速度传感器时，状态判别参数指的是加速度传感器在任意一个或多个坐标轴上的加速度值。此时，此步骤具体为：获取加速度传感器在任意一个或多个坐标轴上的加速度值。When the inertial sensor is an acceleration sensor, the state discrimination parameter refers to the acceleration value of the acceleration sensor on any one or more coordinate axes. At this time, this step specifically includes: acquiring acceleration values of the acceleration sensor on any one or more coordinate axes.
当惯性传感器为加速度传感器时，状态判别参数指的是角运动检测传感器的角速度值。此时，此步骤具体为：获取角运动检测传感器的角速度值。When the inertial sensor is an acceleration sensor, the state discrimination parameter refers to the angular velocity value of the angular motion detection sensor. At this time, this step specifically includes: acquiring the angular velocity value of the angular motion detection sensor.
步骤102、根据状态判别参数确定惯性传感器的工作状态是否正常。Step 102, determine whether the working state of the inertial sensor is normal according to the state discrimination parameter.
在本发明实施例中，检测惯性传感器的工作状态主要是判断惯性传感器是否发生了由于机械硅结构部分的质量块之间、质量块和硅基体之间的黏附而引起的惯性传感器失效。当发生失效时，惯性传感器工作状态为异常。对于是否发生失效，在此主要是通过将获得的状态判别参数和预先设定的参考值进行比较确定的。In the embodiment of the present invention, the detection of the working state of the inertial sensor is mainly to determine whether the inertial sensor fails due to the adhesion between the mass blocks of the mechanical silicon structure part, or between the mass block and the silicon substrate. When a failure occurs, the working state of the inertial sensor is abnormal. As for whether a failure occurs, it is mainly determined by comparing the obtained state discrimination parameter with a preset reference value.
当惯性传感器为加速度传感器时，在此可预先设置一个用于表示惯性传感器工作状态为正常时的加速度范围。该加速度范围表示成[第二加速度阈值，第一加速度阈值]。其中，第一加速度阈值大于第二加速度阈值。由于加速度有正负之分，通常情况下第一加速度阈值为大于0的常数，第二加速度阈值为小于0的常数，且二者的绝对值可以相等。When the inertial sensor is an acceleration sensor, an acceleration range for indicating that the inertial sensor is in a normal working state can be preset here. This acceleration range is expressed as [second acceleration threshold, first acceleration threshold]. Wherein, the first acceleration threshold is greater than the second acceleration threshold. Since the acceleration can be positive or negative, usually the first acceleration threshold is a constant greater than 0, and the second acceleration threshold is a constant less than 0, and the absolute values of the two can be equal.
为了提高判断的准确性，当加速度值大于第一加速度阈值且加速度值大于第一加速度阈值的时间超过第一时间阈值时，确定惯性传感器工作异常；和/或，当加速度值小于第二加速度阈值且加速度值小于第二加速度阈值的时间超过第二时间阈值时，确定惯性传感器工作异常。In order to improve the accuracy of judgment, when the acceleration value is greater than the first acceleration threshold and the time for which the acceleration value is greater than the first acceleration threshold exceeds the first time threshold, it is determined that the inertial sensor is working abnormally; and/or, when the acceleration value is less than the second acceleration threshold And when the time during which the acceleration value is less than the second acceleration threshold exceeds the second time threshold, it is determined that the inertial sensor is working abnormally.
其中，第一加速度阈值和第二加速度阈值可根据实际经验设置。该第一时间阈值和第二时间阈值也可任意设置，并可相同或不同。Wherein, the first acceleration threshold and the second acceleration threshold can be set according to actual experience. The first time threshold and the second time threshold can also be set arbitrarily, and can be the same or different.
当惯性传感器为角速度传感器时，在此可预先设置一个用于表示惯性传感器工作状态为正常时的角速度范围。该加速度范围表示成[第二角速度阈值，第一角速度阈值]。其中，第一角速度阈值大于第二角速度阈值。由于角速度有正负之分，通常情况下第一角速度阈值为大于0的常数，第二角速度阈值为小于0的常数，且二者的绝对值可以相等。When the inertial sensor is an angular velocity sensor, an angular velocity range for indicating that the inertial sensor is in a normal working state can be preset here. This acceleration range is expressed as [second angular velocity threshold value, first angular velocity threshold value]. Wherein, the first angular velocity threshold is greater than the second angular velocity threshold. Since the angular velocity can be positive or negative, usually the first angular velocity threshold is a constant greater than 0, the second angular velocity threshold is a constant less than 0, and the absolute values of the two can be equal.
为了提高判断的准确性，当角速度值大于第一角速度阈值且角速度值大于第一角速度阈值的时间超过第一时间阈值时，确定惯性传感器工作异常；和/或，当角速度值小于第二角速度阈值且角速度值小于第二角速度阈值的时间超过第二时间阈值时，确定惯性传感器工作异常。In order to improve the accuracy of judgment, when the angular velocity value is greater than the first angular velocity threshold and the time for which the angular velocity value is greater than the first angular velocity threshold exceeds the first time threshold, it is determined that the inertial sensor is working abnormally; and/or, when the angular velocity value is less than the second angular velocity threshold And when the time during which the angular velocity value is less than the second angular velocity threshold exceeds the second time threshold, it is determined that the inertial sensor is working abnormally.
其中，第一加速度阈值和第二加速度阈值可根据实际经验设置。该第三时间阈值和第四时间阈值也可任意设置，并可相同或不同。Wherein, the first acceleration threshold and the second acceleration threshold can be set according to actual experience. The third time threshold and the fourth time threshold can also be set arbitrarily, and can be the same or different.
步骤103、当根据状态判别参数确定惯性传感器工作状态异常时，获取震动控制参数。Step 103 , when it is determined according to the state discrimination parameters that the inertial sensor is in an abnormal working state, obtain vibration control parameters.
其中，震动控制参数包括震动频率和震动幅度。该参数是预先设置的。对于不同类型的惯性传感器，其对应的震动控制参数不同，可通过实验的方式获得。Wherein, the vibration control parameters include vibration frequency and vibration amplitude. This parameter is preset. For different types of inertial sensors, the corresponding vibration control parameters are different, which can be obtained through experiments.
步骤104、根据震动控制参数控制移动终端中的震动模块震动，以通过震动模块的震动恢复惯性传感器的工作状态。Step 104: Control the vibration of the vibration module in the mobile terminal according to the vibration control parameters, so as to restore the working state of the inertial sensor through the vibration of the vibration module.
在此，震动模块可利用马达实现。启动马达震动后，马达的震动应力通过移动终端的主板或结构组件传递到三轴加速度传感器，通过此应力可解除加速度传感器的黏附失效。Here, the vibrating module can be implemented with a motor. After the motor is started to vibrate, the vibration stress of the motor is transmitted to the three-axis acceleration sensor through the main board or structural components of the mobile terminal, and the adhesion failure of the acceleration sensor can be relieved through this stress.
由上可以看出，本发明实施例中，当根据惯性传感器的状态判别参数确定惯性传感器工作状态异常时，可根据获取的震动控制参数控制移动终端中的震动模块震动，以通过震动模块的震动恢复惯性传感器的工作状态。从而，利用本发明实施例解决了现有技术中的惯性传感器工作状态异常的问题，提高了用户对移动终端的使用体验。As can be seen from the above, in the embodiment of the present invention, when the inertial sensor is determined to be in an abnormal working state according to the state discrimination parameters of the inertial sensor, the vibration of the vibration module in the mobile terminal can be controlled according to the acquired vibration control parameters, so as to pass the vibration of the vibration module Restore the working state of the inertial sensor. Therefore, the problem of abnormal working state of the inertial sensor in the prior art is solved by using the embodiment of the present invention, and the user's experience of using the mobile terminal is improved.
第二实施例second embodiment
在本发明实施例中，以移动终端设计中采用具有三个作用轴的三轴加速度传感器为例进行为例。其中在例如移动终端的跌落过程中，该三轴加速度传感器的X、Y、Z轴的加速度值有可能为异常。In the embodiment of the present invention, a three-axis acceleration sensor with three active axes is used in the design of a mobile terminal as an example. For example, during the falling process of the mobile terminal, the acceleration values of the X, Y, and Z axes of the three-axis acceleration sensor may be abnormal.
步骤201、预设加速度阈值范围。Step 201, preset the acceleration threshold range.
在此，加速度阈值范围为表示三轴加速度传感器状态正常的加速度范围。如果某一个或多个坐标轴上的加速度值不在此加速度阈值范围内且维持这种情况超过了一定的时间，则说明三轴加速度传感器工作异常。Here, the acceleration threshold range is an acceleration range indicating that the state of the three-axis acceleration sensor is normal. If the acceleration value on one or more coordinate axes is not within the acceleration threshold range and maintains this situation for more than a certain period of time, it means that the three-axis acceleration sensor is working abnormally.
当然，在具体应用中还可以在某一个或多个坐标轴上的加速度值不在此加速度阈值范围内时，认为说明三轴加速度传感器工作异常。Of course, in a specific application, when the acceleration values on one or more coordinate axes are not within the range of the acceleration threshold, it is considered that the three-axis acceleration sensor is working abnormally.
在此，由于坐标轴有正负方向，加速度有正负之分，所以在此假设该加速度阈值范围为[-2g,+2g]。Here, since the coordinate axes have positive and negative directions, and the acceleration can be divided into positive and negative, it is assumed that the acceleration threshold range is [-2g, +2g].
步骤202、获取三轴加速度传感器的预定坐标轴上的加速度值。Step 202. Acquire acceleration values on predetermined coordinate axes of the three-axis acceleration sensor.
在此，假设获取三轴加速度传感器的X、Y、Z轴的加速度值。Here, it is assumed that the acceleration values of the X, Y, and Z axes of the three-axis acceleration sensor are acquired.
步骤203、根据获取的加速度值确定三轴加速度传感器的工作状态是否正常。如果正常，则返回步骤202；否则执行步骤204。Step 203: Determine whether the working state of the three-axis acceleration sensor is normal according to the acquired acceleration value. If normal, return to step 202; otherwise, execute step 204.
经比较，如果有1个坐标轴上的加速度值不在上述加速度阈值范围内且维持这种情况超过了预设时间(如2分钟)，则表示三轴加速度传感器工作异常。以X轴上的加速度值为例，其加速度值为-2.2g且维持为-2.2g的时间超过了2分钟，则表示三轴加速度传感器工作异常。如果3个坐标轴上的加速度值都在上述加速度阈值范围内，则表示三轴加速度传感器工作正常。After comparison, if the acceleration value on one coordinate axis is not within the above-mentioned acceleration threshold range and maintains this situation for more than a preset time (such as 2 minutes), it means that the three-axis acceleration sensor is working abnormally. Taking the acceleration value on the X-axis as an example, if the acceleration value is -2.2g and the time of maintaining -2.2g exceeds 2 minutes, it means that the three-axis acceleration sensor is working abnormally. If the acceleration values on the three coordinate axes are all within the above acceleration threshold range, it means that the three-axis acceleration sensor is working normally.
步骤204、获取震动控制参数。Step 204, acquiring vibration control parameters.
其中，该震动控制参数包括震动频率和震动幅度，可预先存储在存储模块中。因此，在此通过读取存储模块来获取上述震动控制参数。Wherein, the vibration control parameters include vibration frequency and vibration amplitude, which can be pre-stored in the storage module. Therefore, the above-mentioned vibration control parameters are obtained by reading the storage module.
步骤205、根据震动控制参数控制移动终端中的震动模块震动。Step 205: Control the vibration of the vibration module in the mobile terminal according to the vibration control parameters.
在此，震动模块可利用马达实现。启动马达震动后，马达的震动应力通过移动终端的主板或结构组件传递到三轴加速度传感器，通过此应力可解除三轴加速度传感器的黏附失效。Here, the vibrating module can be implemented with a motor. After the motor is started to vibrate, the vibration stress of the motor is transmitted to the three-axis acceleration sensor through the main board or structural components of the mobile terminal, and the adhesion failure of the three-axis acceleration sensor can be relieved through this stress.
步骤206、获取震动模块的震动时长。Step 206, acquiring the vibration duration of the vibration module.
步骤207、判断震动时长是否超过震动时长阈值。如果超过，则流程结束；如果没有，则返回步骤202。Step 207, judging whether the vibration duration exceeds the vibration duration threshold. If exceeded, the process ends; if not, return to step 202 .
其中该震动时长阈值可任意设置。Wherein the vibration duration threshold can be set arbitrarily.
由上可以看出，本发明实施例中，当根据惯性传感器的状态判别参数确定惯性传感器工作状态异常时，可根据获取的震动控制参数控制移动终端中的震动模块震动，以通过震动模块的震动恢复惯性传感器的工作状态。从而，利用本发明实施例解决了现有技术中的惯性传感器工作状态异常的问题，提高了用户对移动终端的使用体验。As can be seen from the above, in the embodiment of the present invention, when the inertial sensor is determined to be in an abnormal working state according to the state discrimination parameters of the inertial sensor, the vibration of the vibration module in the mobile terminal can be controlled according to the acquired vibration control parameters, so as to pass the vibration of the vibration module Restore the working state of the inertial sensor. Therefore, the problem of abnormal working state of the inertial sensor in the prior art is solved by using the embodiment of the present invention, and the user's experience of using the mobile terminal is improved.
