Platform door control method and device for removing electromagnetic lock

The invention provides a platform door control method and device for removing an electromagnetic lock. The method comprises the steps that a gear state of a platform door local control box LCB is judged when a door control system is normal; when the gear state is a manual closing position, a transmission mechanism is driven to execute door closing operation, after closing is completed, a safety circuit of a platform door is conducted, a motor is kept in an enabled state so as to provide door closing state locking force, and the door closing state locking force is used for keeping the closing completion state of the platform door; and when the gear state is a manual opening state, the transmission mechanism is driven to execute door opening operation, after the safety circuit of the platform door is disconnected and opened, the motor is kept in an enabled state to provide door opening state maintaining force, and the door opening state maintaining force is used for maintaining the opening completion state of t
