Abstract

The invention relates to standardization correction technology of a micro-electromechanical systems (MEMS) acceleration sensor, in particular to multi-parameter batch test equipment of the MEMS acceleration sensor. The multi-parameter batch test equipment of the MEMS acceleration sensor solves the problems that existing standardization correction technology is long in standardization correction time consumption, low in standardization correction efficiency, and limited in standardization correction ability, and can not achieve batch automatic standardization correction. The multi-parameter batch test equipment of the MEMS acceleration sensor comprises a changeable environment device, a batch standardization test platform, an automatic clamping and mounting platform, a multi-channel data collection system, a changeable environment control system, a clamping and mounting control system and a main control system. The batch standardization test platform, the automatic clamping and mounting platform and the changeable environment control system are arranged in a changeable environment device. A signal output end of the multi-channel data collection system is connected with a signal input end of the main control system. The invention is applied to standardization correction of the MEMS acceleration sensor.

Description

technical field [0001] The invention relates to a calibration and calibration technology for MEMS acceleration sensors, in particular to a multi-parameter batch testing device for MEMS acceleration sensors. Background technique [0002] MEMS acceleration sensors are widely used in the automotive industry, industrial process control, medical care, consumer electronics, environmental protection and other fields. MEMS acceleration sensors need to be calibrated and calibrated through various tests for performance parameters after development and before use. According to different calibration requirements, MEMS acceleration sensors need to undergo mechanical tests, environmental tests, long-term stability and repeatability tests, etc. Among them, the mechanical test is divided into static test and dynamic test. Static tests include gravity field flip test, centrifugal test, etc. Dynamic tests include dynamic tests, vibration tests, etc. Environmental tests include temperature...
