System for detecting contact between mechanism and ground

The embodiment of the invention discloses a system for detecting contact between a mechanism and the ground. The system can comprise a first subsystem used for ground contact detection of an electrically-driven supporting leg and a second subsystem used for ground contact detection of a hydraulic transmission supporting leg, current detection and position detection are added on the basis of an electrically-driven supporting leg driving scheme, pressure detection is added on a hydraulic-electric control loop, a position detection ring is arranged in an oil cylinder, and the hydraulic transmission supporting leg is driven by the hydraulic-electric control loop. The ground contact detection of the electrically-driven supporting leg and the hydraulic transmission supporting leg is realized, the manual operation process is reduced, and the possibility of major accidents caused by infirm foundation of the working platform due to inaccurate judgment is avoided at the same time. 本发明实施例公开了一种机构接触地面的检测系统。该系统可包括用于电驱动支腿的触
