Specifically, a detection program, i.e., a predetermined program, of the acceleration sensor is preset in the computer. The flap 202 is placed parallel to the table 201 while the rotating table 206 has the pointer 216 pointing to the 0 degree scale, i.e., the flap 202 is at the 0 degree position. Starting a preset program, reading initial values of the detection box 211, the level meter 212 and the vibration sensor 213 by a computer, wherein the initial values of the detection box 211, the level meter 212 and the vibration sensor 213 are all 0, the computer automatically runs the preset program after the initial values accord with the preset values (the preset values are 0) of the detection box 211, the level meter 212 and the vibration sensor 213, the preset program starts the rotary air cylinder 209 to drive the rotary table 206 to rotate left and right in a reciprocating manner at a constant speed according to the program, namely the rotary table 206 rotates leftwards to a left 45-degree scale, and the rotary direction rotates rightwards to a right 45-degree scale, and meanwhile, the computer acquires real-time detection data of the detection box 211, the level meter 212 and the vibration sensor 213.

The turntable continues to keep the turntable 206 rotating back and forth from side to side while the computer continues to acquire real-time inspection data of the level gauge 212, the vibration sensor 213, and the inspection box 211.
S50, the computer calculates the acceleration value of the acceleration sensor at the 45-degree position through a preset program, judges whether the acceleration of the acceleration sensor at the 45-degree position falls within a set second threshold range, if yes, the detection of the acceleration sensor is qualified, and the detection is finished; if not, the acceleration sensor fails to detect the acceleration at the 45-degree position, and the detection is ended. Specifically, the computer calculates the acceleration value of the acceleration sensor at the 45-degree position through a preset program according to the detection data acquired in the previous step, and compares the acceleration value at the 45-degree position with a preset second threshold range, wherein the second threshold range refers to a standard or qualified range value of the acceleration sensor of the product or object at the 45-degree position. And if the detected acceleration value at the 45-degree position is within the second threshold range, the acceleration sensor meets the requirement, and the detection is finished.
