Problems solved by technology
Among them, the most commonly used sensor is the acceleration sensor, especially after the built-in acceleration sensor on the smart mobile terminal, the smart mobile terminal has added new functions such as a pedometer, horizontal or vertical screen detection, and an electronic compass. These functions are also used by users. Widely used, and once the acceleration sensor is defective, the raw acceleration data sensed by it will be biased, which will affect the use of related applications in the mobile terminal, so the correctness of the raw acceleration data sensed by the acceleration sensor is very important
[0003] In the prior art, it is only possible to judge whether the application function in the mobile terminal is abnormal, but whether there is a deviation in the raw acceleration data sensed by the acceleration sensor used by the application function is not possible in the prior art.

The invention discloses an acceleration sensor test method and an acceleration sensor test system based on a mobile terminal. The method comprises the following steps: when a mobile terminal moves at a preset acceleration, acquiring the display brightness of the screen of the mobile terminal; acquiring a first acceleration corresponding to the display brightness according to the corresponding relationship between the display brightness and the first acceleration acquired by an acceleration sensor; and comparing the first acceleration with the preset acceleration, and deciding that the first acceleration acquired by the acceleration sensor is biased if the first acceleration is inconsistent with the preset acceleration. The original data of the acceleration sensor can be acquired only based on the display brightness of the mobile terminal when the mobile terminal moves at the preset acceleration and the corresponding relationship between the display brightness and the first acceleration acquired by the acceleration sensor, calculation is simple, defects can be found as early as possible, and the problem that an application in the mobile terminal for calling the original data of the acceleration sensor fails during use is avoided.
Description
technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a testing method and system for an acceleration sensor based on a mobile terminal. Background technique [0002] Currently, various sensors are commonly installed on mobile terminals to improve the mobile terminal's ability to sense user operations, making the mobile terminal more intelligent. Among them, the most commonly used sensor is the acceleration sensor, especially after the built-in acceleration sensor on the smart mobile terminal, the smart mobile terminal has added new functions such as a pedometer, horizontal or vertical screen detection, and an electronic compass. These functions are also used by users. It is widely used, and once the acceleration sensor is defective, the raw acceleration data sensed by it will be biased, which will affect the use of related applications in the mobile terminal. Therefore, the correctness of the raw acceleration data sensed b...
