However, the existing electric cylinder movement detection usually adopts manual detection, using a runout meter for real-time observation and detection, and requires manual installation of the load block at the push-out end of the electric cylinder. The operation is difficult and there are certain risks. It cannot meet the needs of high-precision and high-stability movement detection, and cannot perform multi-angle detection of the electric cylinder load-bearing movement at the same time, and cannot automatically monitor and detect.
