Current monitoring system and control method of mobile crushing and screening station

The invention provides a current monitoring system and control method of a mobile crushing and screening station. The current monitoring system is characterized in that a residual current transformerand an intelligent monitoring device are arranged at a power input side, a crushing host motor is provided with a three-phase current transformer, a current conversion control device and a current andvoltage meter, each belt transmission machine is provided with an intelligent monitoring device, and the intelligent monitoring device is used for monitoring a motor current, a residual current and avoltage in real time. The control system integrally employs a CAN-OPEN, J1939 site bus technology, monitoring current data information of a dragging unit is transmitted to a controller in real time,system program is used for analyzing current data and comparing with various built-in working condition mode libraries, a transmission device is intelligently controlled, and automatic adaption to different working conditions is
