Detection system and positioning method for stacking trolley on gate-type stacker-reclaimer

The invention relates to the technical field of gate-type stacker-reclaimers, in particular to a detection system of a stacking trolley on a gate-type stacker-reclaimer and a positioning method of the stacking trolley on the gate-type stacker-reclaimer adopting the detection system. The detection system of the stacking trolley on the gate-type stacker-reclaimer comprises current signal detectors, a PLC and a system server, the current signal detectors are installed in primary electrical loops of driving motors on four walking wheels of the stacking trolley, and the PLC is in signal connection with the stacking trolley, the current signal detectors and the system server at the same time. According to the detection system of the stacking trolley on the gate-type stacker-reclaimer, current effective values of driving motors on four walking wheels of the stacking trolley can be obtained through continuous measurement of a current signal detector and transmitted to a PLC, and the PLC processes the current effectiv
