Inertial sensor test system and test method based on double-shaft turntable

Abstract

The invention discloses an inertial sensor test system and test method based on a double-shaft rotary table, and belongs to the technical field of sensor calibration, the inertial sensor test system comprises a host configured with main control system software, a rotary table industrial personal computer, an external switching box and the double-shaft rotary table connected with the rotary table industrial personal computer and the external switching box, the internal adapter male plug and the internal adapter female plug are connected through the L-shaped adapter line, so that the effective space between the turntable and the base can be reasonably utilized, the length of a connecting line between the internal adapter male plug and the internal adapter female plug is reduced, and signal transmission interference caused by winding of too many or too long connecting lines is avoided; the internal connecting line is of a clip-like appearance structure, and the clip-like appearance structure has certain strength, so that the internal connecting line can be prevented from deforming in the sensor testing process, and mutual interference of transmission signals caused by large position change of the internal connecting line due to deformation of the internal connecting line can be avoided; and the automatic calibration precision of the inertial navigation sensor can be improved.

Description

technical field [0001] The invention relates to the technical field of sensor calibration, in particular to an inertial sensor testing system and testing method based on a biaxial turntable. Background technique [0002] The process of using standard instruments to calibrate the sensor is called calibration. Specifically for piezoelectric pressure sensors, use a dedicated calibration device, such as a piston pressure gauge, to generate a known standard force on the sensor, and the sensor will output a corresponding charge signal. Known standard detection equipment measures the charge signal to obtain the magnitude of the charge signal, and thus obtain a set of input-output relations. Such a series of processes is the calibration process of the piezoelectric pressure sensor. Among them, the three-axis turntable is widely used in the calibration of various direction sensors, and its structural stability and repeat positioning accuracy have a decisive influence on the measurem...

AI Technical Summary

Problems solved by technology

The traditional two-axis turntable equipment can only measure one piece at the same time, the number of measurements is small and the equipment is manually controlled

Moreover, during the test period, it is necessary to manually monitor the data and control the equipment manually, so the working hours are very long, which is a great test of human experience and physical strength, as well as a great test of the operator's technical level and endurance.

At present, there is no corresponding automation equipment or products in the domestic market, and there is no corresponding automatic collection system, and the system needs to be updated in real time to meet the needs of future development
