The invention belongs to the field of elevator electric safety detection and provides an elevator door lock short circuit preventing system which comprises a main control panel and N floor detecting systems. The main control panel communicates with the N floor detecting systems in a two-way mode. Each floor detecting system comprises an N

    floor door lock loop, an N subsidiary detecting point connected to the N floor door lock loop in series, an N floor board, and an N redundancy door lock detecting point, wherein the N redundancy door lock detecting point is in linkage with the N subsidiary detecting point and is connected with the N floor board, and N is a natural number larger than zero. The elevator door lock short circuit preventing system is simple in structure, has a door lock detecting function when an elevator arrives at a stop, has a door lock detection function when a port of an elevator door lock loop is short circuited, accurately detects whether a door lock is short circuited or not, and solves the problem of potential safety hazards fundamentally.
