[Abstract]:MEMS inertial sensors have been widely used in electronic toys, smart machinery, mobile phones, medical devices, automotive electronics, navigation, attitude measurement. Intelligent ammunition and other civil and military fields, but the MEMS inertial sensor test calibration is still manual, single-piece, low efficiency test calibration, long time. It is easy to make mistakes. In order to improve the traditional testing and calibration method, a set of MEMS inertial sensor automatic batch test calibration system is designed. According to the required function and performance index of the system. The overall structure of the system is designed. The system mainly includes the lower computer, the upper computer and the three-axis turntable, and the lower computer includes the multi-channel data acquisition card. Ethernet switch and data storage and processing module. This paper describes the hardware design and software design of the lower computer in detail, and introduces the software design of the upper computer, as well as the hardware design of the lower computer. The paper discusses the data acquisition circuit design of MEMS inertial sensor for analog signal output, SPI output and serial port output, Ethernet data transmission circuit design in turn. The design of SD card backup storage circuit and power supply circuit, as well as the design of data storage and processing module. In the software design of the lower computer, the data acquisition program design of three kinds of multi-channel data acquisition card is introduced. Ethernet communication program design SD card storage program design and data storage and processing module program design. In the host computer software, mainly introduces the host computer software development environment. The software flow and the realization of the main function modules. The system can test and calibrate 64 MEMS accelerometers, 32 MEMS gyroscopes, or more than 8 MIMU at the same time. It has the functions of selecting experimental items, automatically controlling the power off of the sensor, automatically controlling the three-axis turntable and selecting the sampling rate. At the end of the paper, the test results of the main function modules of the system are given. The process of testing and calibrating the MEMS inertial sensor and the static zero bias and static multi-position test of the MEMS accelerometer are carried out. The results of MEMS gyroscope static zero-bias and rate experiments and MIMU calibration experiments show that the system can automatically calibrate multiple MEMS inertial sensors. Compared with the traditional single test calibration, the efficiency of manual testing and calibration is greatly improved, and the input of manpower is reduced.
