Design of automated batch calibrating system for MIMU

Abstract

Considering the disadvantages of low efficiency and huge demand for manpower, the automated batch calibrating system for MIMU(MEMS Inertial Measurement Units) is designed. The system mainly consists of muti-channel data acquisition, data storage and data processing module and automatic control module. MIMUs' datas are transmitted through Ethernet interface and control instructions are transmitted via serial port. The system can calibrate at most 16 MIMUs at the same time and can calculate calibration parameters automatically. The system also has the function of automatic power control and fault alarm, etc. A test for this system has been implemented, and the results showed that the system was reliable and effective and reduced the manpower to a great extent.
