The invention provides a control system for preventing an elevator car from accidentally moving. The control system comprises a door area signal collecting unit, an elevator car shaft position positioning unit, an elevator control center, a current disjunction unit and an elevator braking unit. The signal output end of the door area signal collecting unit and the signal output end of the elevator car shaft position positioning unit are connected with the signal input end of the elevator control center. The elevator control center output signals to the current disjunction unit to control the elevator braking unit. When the elevator car is not located at the door area position and the elevator car accidentally moves under the door opening state, the elevator car can be effectively stopped, and major safety accidents are avoided. Meanwhile, an existing elevator system does not need to be greatly modified, and elevators in the using process or elevators in the producing process can be conveniently refitted.
