AI Technical Summary
Existing radar dome electrical performance testing systems, under complex shapes and diverse motion postures, cannot effectively prevent uncontrolled collisions of mechanical subsystems due to conventional limit control methods, leading to equipment damage and economic losses.
By combining a wide-range, high-sensitivity flexible pressure sensor with a signal converter, and through a multi-point control design, the movement status of the radar dome is monitored in real time, and the turntable movement is stopped immediately when it approaches the limit position or when there is a risk of collision.
This improved the safety and efficiency of radome testing, reduced the probability of equipment collisions and human intervention, and ensured the stable operation of the system.
