Abstract:The test system for a certain type of liquid floating gyro stable platform is quite complicated and the degree of automation is not high, it is proposed to apply LXI bus technology and IVI technology to the liquid floating gyro stable platform test system and automated this system. The application of LXI bus technology and IVI technology reduces the difficulty of system development, improve system test accuracy, reliability and scalability. The system can well complete the function and accuracy test of the liquid floating gyro stable platform.
