Multi-channel MEMS (Micro-Electro-Mechanical System) gyroscope calibration test data collection device and collection method

Abstract

The invention discloses a multi-channel MEMS (Micro-Electro-Mechanical System) gyroscope calibration test data collection device. A processor communication interface of a CAN (Controller Area Network)transceiver of the multi-channel MEMS gyroscope calibration test data collection device is connected with a CAN controller interface of a DSP (Digital Signal Processing) processor; a first channel gating signal communication end of the DSP processor accesses a gating signal interface of each MEMS gyroscope angular rate sensor of a first MEMS gyroscope angular rate sensor group through a level translator; a second channel gating signal communication end of the DSP processor accesses a gating signal interface of each MEMS gyroscope angular rate sensor of a second MEMS gyroscope angular rate sensor group through a level translator; and each SPI (Serial Peripheral Interface) communication interface of the DSP processor is connected with an SPI communication interface of the corresponding MEMSgyroscope angular rate sensor through a level translator. The multi-channel MEMS gyroscope calibration test data collection device realizes rapid MEMS gyroscope calibration test data collection withmultiple channels.

Description

technical field [0001] The invention relates to the technical field of testing and data collection, in particular to a multi-channel MEMS gyroscope calibration test data collection device and a collection method thereof. Background technique [0002] In many fields such as automobile manufacturing, industry and aerospace, there are many applications of platform stability control, and gyroscopes are indispensable. Due to the large volume of traditional gyroscopes, the early stable tracking platforms often have disadvantages such as bulky, heavy, poor reliability, expensive, high failure rate, and difficult maintenance in practical applications. With the maturity of technology and the improvement of manufacturing level, domestic and foreign platform stabilization systems are developing in the direction of lighter weight, smaller volume, higher stabilization accuracy, lower price, better reliability, and easier maintenance.

Problems solved by technology

[0005] The temperature compensation data acquisition system of MEMS gyroscope ADIS16060 is an evaluation board provided by ADI. The evaluation board can only collect the data information of one gyroscope at a time at each temperature point. Through the design of test tooling and test cables, although it can be processed in batches , but it is still necessary to manually switch the gyro test cable and repeatedly switch the power supply, and there are many cables, the cost is high, the efficiency is low, and it may cause misoperation, so this evaluation test board is not conducive to nor suitable as a product batch Gyro Temperature Compensation Calibration Data Acquisition System in Production Stage
