An elevator visual intercom system for a subway station belongs to the technical field of visual intercom. The invention aims to solve the problem that the traditional existing subway intercom systemdoes not have a video function and the problem that the intercom is not clear due to the fact that an analog signal transmission intercom system is easily interfered. The system comprises a pluralityof sets of elevator side equipment and a set of control room side equipment. A plurality of sets of floor intercom units, a plurality of sets of floor visual units and a lift car visual unit of each piece of elevator side equipment are connected into a linkage control box through network cables. A visual intercom host of the control room side equipment is electrically connected with car intercom units, car roof intercom units, pit intercom units and machine room intercom units of the elevator side equipment through the linkage control boxes. The plurality of sets of linkage control boxes are respectively connected to a light convergence switch through optical fibers. The visual intercom host is connected to the light convergence switch through a network cable. The elevator visual intercomsystem is mainly used for elevator visual intercom of subway stations.
