When the emergency stop button is pressed, the wireless remote controller sends an emergency stop signal to the remote controller receiving module 3; the remote controller receiving module 3 transmits the emergency stop signal to the PLC digital quantity input module 43 through the I001 signal output end; then the input signal of the PLC digital quantity input module 43 triggers the PLC output, controls the soft emergency stop of the triggering device, so that the shuttle vehicle stops the current motion action, and it is reported that the remote controller emergency stop has been triggered. Meanwhile, the remote controller is provided with a walking brake button; when the remote controller receiving module 3 receives the brake walking signal, it is transmitted to the PLC digital quantity input module 43, so that the input signal of the PLC digital quantity input module 43 triggers the PLC output, and the brake of the shuttle vehicle walking motor is opened; the start walking is the same; the steering, rotation and other operations in the running process of the actual four-way shuttle vehicle are realized through the Internet of Things.
