Abstract

An elevator system is provided, in which when a telephone in an information center receives an emergency call using an analogue public telephone network from an interphone of an elevator, a monitoring person in the information center can confirm information of the elevator which transmits the emergency call while responding to the emergency call by the telephone. To this end, the elevator system includes: means configured to add, as an identification voice signal, identification information to a call voice signal input to an intercom provided inside each of cars of elevators, the identification information enabling the elevator in which the intercom is installed to be specified; means configured to transmit, with an analog signal, the call voice signal to which the identification voice signal is added; means configured to reproduce the call voice signal included in the transmitted analog signal; means configured to extract the identification information from the identification voice signal included in the transmitted analog signal; and a monitoring terminal configured to acquire, from a server configured to store information on the elevator specified by the identification information in association with the identification information, information on the elevator associated with the identification information extracted from the identification voice signal and to display the acquired information.
