The invention discloses a double-channel elevator door lock loop electronic detection system and method. The system comprises a first optical coupling sampling isolating circuit, a second optical coupling sampling isolating circuit, an OR gate operating circuit, a motor torque output circuit and a control circuit. The first optical coupling sampling isolating circuit and the second optical coupling sampling isolating circuit independently detect on-off of an elevator door lock loop and output on-off signals of the isolated elevator door lock loop. The OR gate operating circuit is used for conducting hardware OR gate operation on the on-off signals of the elevator door lock loop. Output signals of the OR gate operating circuit are divided into motor torque output circuit enable signals andcontrol circuit control signals. The motor torque output circuit and the control circuit realizes synchronization of hardware control and software control to start or shut down the corresponding functions of the elevator door lock loop during on-off operation. The double-channel elevator door lock loop electronic detection system can improve the detection reliability of the elevator door lock loop, prolong the service life of the elevator door lock loop, reduce motion noise of a detection unit, reduce the cost and occupied space and improve the reliability and competitive advantages of an elevator.
