Gyroscope testing system and method

Abstract

The invention relates to the field of gyroscopes, and concretely relates to a gyroscope testing system and method. The test efficiency is improved, the gyroscope delivery efficiency is further improved. The method comprises the following steps: respectively acquiring data values of X-axis gravitational acceleration, Y-axis gravitational acceleration and Z-axis gravitational acceleration of a groupof gyroscopes in a normal working mode and a test mode through a control module; calculating an X-axis gravitational acceleration difference value, a Y-axis gravitational acceleration difference value and a Z-axis gravitational acceleration difference value corresponding to the two modes; checking whether the difference value is within a preset driving data range simulated by the test mode; if so, returning test qualification to an upper computer by the control module; and if not, returning test disqualification to the upper computer by the control module.

Description

technical field [0001] The technology of the invention relates to the field of gyroscopes, in particular to a gyroscope testing system and method. Background technique [0002] Gyroscopes are more and more widely used in electronic equipment. Although gyroscope parts manufacturers have quality assurance for the devices, defective products may inevitably appear in the manufacturing process of the equipment, so it is necessary to remove these defective products in the manufacturing process. Screened out, the screening test of gyroscope devices currently basically relies on simulating the preset environment, and then compares the measured parameters with the preset values ​​to evaluate whether the gyroscope is qualified. These solutions are extremely difficult to implement in actual production, which seriously affects the gyroscope. The test efficiency of the gyroscope seriously affects the accuracy of the test results of the gyroscope, and further affects the quality of the gy...

Screened out, the screening test of gyroscope devices currently basically relies on simulating the preset environment, and then compares the measured parameters with the preset values ​​to evaluate whether the gyroscope is qualified. These solutions are extremely difficult to implement in actual production, which seriously affects the gyroscope. The test efficiency of the gyroscope seriously affects the accuracy of the test results of the gyroscope, and further affects the quality of the gyroscope when it leaves the factory.
