Abstract

The invention relates to a testing system for a micro-inertial measurement unit, belonging to the technical field of test calibration of the micro-inertial measurement unit. According to the testing system, the micro-inertial measurement unit to be tested is arranged on a three-axle turntable; the turntable is controlled to rotate according to the test requirement by a turntable control device; an input end of an industrial personal computer is connected with the micro-inertial measurement unit arranged on the three-axle turntable by a test interface; the industrial personal computer is used for measuring and calibrating the performance parameters of the micro-inertial measurement unit by a LabView microsoftware platform; the acquired data is directly stored in a folder by the LabView platform; the data is directly read from the LabView microsoftware platform, and is calculated and processed; the testing system is high in operation efficiency; modularization is realized by the LabView microsoftware platform, so that the testing system is convenient, fast and high in portability.

Description

technical field [0001] The invention relates to a test system of a micro inertial measurement unit, belonging to the technical field of micro inertial measurement unit test calibration. Background technique [0002] MEMS inertial measurement units have advantages that traditional inertial devices do not have. The application of MEMS IMUs on air-to-air missiles requires a series of tests and experiments to verify the performance indicators. There is no unified industry standard in China. The United States, Japan and Russia Other countries have launched device and application research in this area, and have achieved certain results. The test technology based on the LabView software platform has been applied in test equipment, but it has not been used in the test of micro-inertial devices. Relevant units in China separate testing and data processing, that is, first collect and record data, and then export the data for manual processing, or import the data into Matlab for calcu...
