The invention relates to the field of elevator safety control, and provides a protection circuit for accidental movement of an elevator car. The elevator car accidental movement protection circuit comprises a door sealing lock feedback loop, a door sealing relay output loop and a door area detection loop. The door sealing lock feedback loop is connected with a main controller of the elevator and is used for feeding back a door sealing or opening signal of the door lock; the door sealing relay output loop is used for feeding back the state of the door sealing relay; the door area detection loop is connected with the door sealing lock feedback loop and a safety loop of an elevator and used for feeding back the state of a door area switch and controlling on-off operation of all safety relays in the safety loop and the door sealing lock feedback loop. According to the obtained information of the safety relay and the door area switch, feedback information of the door sealing lock and information of the door sealing relay are obtained, door sealing information is sent to the main controller, and therefore safe operation of an elevator is controlled.
