A third embodiment of the present invention relates to a method for testing a sensor. The method for testing the sensor is mainly applied to a testing device of the sensor provided in any embodiment of the invention, and particularly, when the sensor in the mobile terminal needs to be tested, the mobile terminal is fixed on a first terminal fixing component or a second terminal fixing component in the testing device of the sensor according to the sensor to be tested, and then the first terminal fixing component or the second terminal fixing component is adjusted according to the testing requirement of the sensor to be tested, so that the performance of the sensor to be tested is tested. Or when the sensor in the mobile terminal needs to be tested, the mobile terminal is fixed on the second terminal fixing component according to the sensor to be tested, the test card is fixed on the test card fixing component in the test device of the sensor, and then the second terminal fixing component and/or the test card fixing component are adjusted according to the test requirement of the sensor to be tested, so that the performance of the sensor to be tested is tested.
Specifically, the sensors to be tested in the present embodiment may specifically be acceleration sensors, angular velocity sensors, geomagnetic sensors, proximity sensors, and the like, and for convenience of understanding, the method for testing the sensors will be described below by taking the sensor to be tested as an acceleration sensor as an example, and a specific flow is shown in fig. 3.
In step 301, the mobile terminal is secured to the first terminal holding assembly.
In step 302, the first terminal fixing assembly is adjusted to a vertical fixing placement state.
In step 303, a first clamp holding the mobile terminal is rotated.
In step 304, when the screen of the mobile terminal is switched, the currently pointed scale on the first circular scale is read and recorded.
Through the above description, it is easy to find that, after the sensor to be tested is an acceleration sensor and the mobile terminal is fixed on the first terminal fixing component, the tester needs to manually adjust the first terminal fixing component to be in a horizontal or vertical fixed placing state or by a main control device of the testing device for controlling the sensor. And then, the circle center of a first circular dial in the first terminal fixing assembly is taken as a rotating shaft point of the mobile terminal, and the first clamp for fixing the mobile terminal is rotated anticlockwise or clockwise until the screen of the mobile terminal is switched, such as a horizontal screen and a vertical screen. After the screen of the mobile terminal is sent and switched, the scales pointed by the mobile terminal on the first circular dial are read and recorded, one-time recording is completed, the recorded numerical value is compared with the preset numerical value, and therefore whether the switching angle of the acceleration sensor and the screen are abnormally detected or not can be determined according to the comparison result.
It should be noted that, since fig. 3 illustrates a state where the first terminal fixing assembly is vertically and fixedly disposed, when the first clamp for fixing the mobile terminal is rotated, the first clamp is required to be rotated clockwise, and if the first terminal fixing assembly is horizontally and fixedly disposed in practical applications, the first clamp is required to be rotated counterclockwise.
In addition, it is worth mentioning that the testing device can also be used for detecting the static deviation performance of the acceleration, specifically, when the function is tested, an engineering mode of an acceleration sensor installed in the mobile terminal needs to be opened first, the mobile terminal is fixed on the first clamp, the first circular dial is placed horizontally or vertically, acceleration values of gravity in a three-dimensional space are recorded in an adjusting process, such as the direction of an X axis, the direction of a Y axis and the direction of a Z axis, and after test data are obtained, preset values of the data obtained through testing are compared, so that the static deviation performance of the acceleration sensor is detected.
In addition, when testing an angular velocity sensor in a mobile terminal, for example, a gyroscope, the testing process is substantially the same as the process of testing an acceleration sensor, specifically, when the sensor to be tested is an angular velocity sensor, the first terminal fixing assembly is adjusted to be in a horizontally fixed placement state, and the first clamp is rotated until the mobile terminal rotates 360 °, or the first clamp is adjusted to be in a state in which the fixed mobile terminal is vertically placed, and the first disk is controlled to rotate clockwise, or the first clamp is adjusted to be in a state in which the fixed mobile terminal is horizontally placed, and the first disk is controlled to rotate clockwise. And then acquiring a data value generated by the angular velocity sensor in the test process, comparing the generated data value with a preset value, and determining the performance of the angular velocity sensor according to the comparison result.

For example, after the mobile terminal provided with the angular velocity sensor and the angular velocity testing tool is fixed in the first fixture, the first circular dial is horizontally and fixedly placed, the first fixture is rotated at a constant speed, and the current output waveform is obtained through the acceleration testing tool, so that the test in the Z-axis direction is realized.
For example, after the mobile terminal provided with the angular velocity sensor and the angular velocity testing tool is fixed in the first fixture, the first circular dial is horizontally placed, the mobile terminal is adjusted to be in a vertically placed state, the first fixture is fixed, the first circular dial is rotated, the current output waveform is obtained through the acceleration testing tool, and therefore detection in the Y-axis direction is achieved.
In addition, with the testing device provided in this embodiment, it can also be tested whether the angular velocity sensor is in a static state, specifically, when testing the function, an engineering mode of the angular velocity sensor installed in the mobile terminal needs to be opened first, the mobile terminal is fixed on the first fixture, the first circular dial is horizontally or vertically fixed, the maximum values of the angular velocity sensor in the X-axis direction, the Y-axis direction and the Z-axis direction when standing are recorded in the adjustment process, and after the test data is obtained, the preset values of the data obtained by the test are compared, so as to determine the new output energy of the angular velocity sensor in the static state.
The angular velocity sensor described in the present embodiment may specifically be a gyroscope.
The test device of the sensor is used for testing the acceleration sensor and the angular velocity sensor in the mobile terminal, a tester does not need to replace the test device, the two sensors can be tested by using the same test device, the tester does not need to hold and fix the mobile terminal and the test device in the whole test process, one tester can complete the whole test process, the labor is greatly saved, and the test can be faster. And (4) accurately acquiring a test result.
