Motion control system for shielding door control device

The invention provides a motion control system for a shielding door control device. The motion control system is characterized by comprising a motion control chip module, an input signal interface module, an output signal interface module, an MODBUS communication interface module in communication with a central control disc and a CANBUS communication interface module in communication with an actuating mechanism driving system, wherein connection circuits between the interface modules and the motion control chip module are provided with isolating circuits. Modular design is adopted in the motion control system for the shielding door control device, the motion control system is convenient to maintain, signal interference is reduced through the isolation circuits, and misoperation of a shielding door is reduced.
