The invention discloses a detecting method of short circuit of a door lock loop of an elevator landing door, wherein a switch contact of a landing door of every layer respectively connects two sampling leads to a detecting transfer slab; the detecting transfer slab is connected with a calling plate in an elevator calling box of every layer; the calling plate is controlled by an elevator control system. by adopting the method of automatically detecting the short circuit of the safety loop of the door lock through the elevator control system, the detecting method completely avoids that the safety loop of the landing door lock is shortly circuited; and thereby, the detecting method avoids the elevator accident caused by shortly-circuited safety loop, and improves the safety performance of the elevator.
