Abstract

[0001] The present invention relates to a signal transmission device of a group management elevator, in which a hall station is connected to a hall station, each hall station is connected to a corresponding call control device, and each call control device is connected to a group management device There is a problem in that when a failure occurs in the transmission line between the group management apparatus and each of the air conditioner control apparatuses, two cars respond to the landing station calling call to increase power consumption. In order to solve such a conventional problem, the present invention has a group managing means for allocating an air conditioner having an optimal condition through a transmission line when a serial call landing call is made; Each of the air conditioner control means for controlling the operation of the corresponding air conditioner under the control of the group management means; Each hall station for transmitting a hall call signal and a status signal of a call through a serial signal transmission line; And a hall host for transmitting a serial signal between the hall station and the group management means. In this way, the hall calling signal is transmitted serially to the group management apparatus through the hall host, The command command for controlling the movement of the call control device is transmitted to the corresponding call control device through another transmission signal so that even if an abnormality occurs in the transmission line between the group management device and the call control device, .
