The invention relates to a device, system and method for automatically detecting an elevator hall door lock. The device comprises hall door lock signal collection modules and hall door lock signal transmission modules. The hall door lock signal collection modules and the hall door lock signal transmission modules are arranged in hall-call boards. The hall door lock signal collection modules are connected with hall door lock circuits. The hall door lock signal transmission modules are connected with an elevator control board through a bus. The hall door lock signals of the hall door lock circuits are connected in the hall door lock signal collection modules. When the hall door lock signals connected in the hall door lock signal collection modules are disconnected, the hall door lock signal transmission modules send a hall door lock abnormal signal and a corresponding floor number to the elevator control board through the bus. According to the scheme, abnormality of the hall door lock signals can be automatically monitored in time, the floor where a failure is located can be fast located when an elevator hall door is abnormal, an elevator can be maintained conveniently as soon as possible, and effective protection on personal safety of passengers in the elevator is achieved.
