The invention relates to the technical field of elevators, and discloses an elevator door lock detection system. The elevator door lock detection system comprises a braking device, at least one first safety plate and at least one second safety plate, and the first safety plate and the second safety plate are connected through a safety bus. The first safety boards receive state signals of all door lock contacts, and all the first safety boards send the state signals to the second safety board through the safety bus; the second safety plate controls the braking device to brake the elevator when any door lock contact is disconnected. Compared with a traditional elevator loop, the elevator loop can detect and accurately position a door lock which is short-circuited or breaks down in an elevator in time, and safety accidents are avoided.

    本发明涉及电梯技术领域,公开了一种电梯门锁检测系统。本发明中,该电梯门锁检测系统,包括:制动装置、通过安全总线连接的至少一个第一安全板和第二安全板;第一安全板接收所有门锁触点的状态信号,且各第一安全板均通过安全总线向第二安全板发送状态信号;第二安全板在任一门锁触点断开时控制制动装置制动电梯。相比传统的电梯回路,能够及时检测并精准定位到在电梯中被短接或出现故障的门锁,避免安全事故的发生。
