Remote monitoring system

Abstract

A remote monitoring system that inputs a transmission signal from a user of a remote monitoring object and outputs a call signal to a telephone set in a remote monitoring center. The remote monitoring system includes a plurality of remote monitoring centers and switches, and the switches are provided with: a sending signal input unit, which inputs a sending signal including a representative telephone number; a storage unit, which stores the telephone numbers of each telephone set in each remote monitoring center organization; a retrieval unit , retrieve the telephone number of the telephone set in the remote monitoring center organization; the calling part, output the calling signal; the remote monitoring center has: the calling signal input part, input the calling signal; the setting part, set the execution of the transmission of the calling signal; The output unit, when it is set to not execute the transmission of the call signal, re-outputs the call signal to the telephone set corresponding to the called telephone number; The transmission control of the call signal of the telephone set corresponding to the telephone number.

Description

technical field [0001] The present invention relates to a remote monitoring system that inputs a transmission signal from a user of a remote monitoring object such as an elevator and outputs a call signal to a telephone set in a remote monitoring center. Background technique [0002] Conventionally, there is a system in which a user of an elevator can communicate with an operator of a remote monitoring center when an elevator breaks down or the like. [0003] In this system, a remote monitoring center is installed in each pre-divided region, and a representative telephone number unique to each region is assigned to the remote monitoring center. When the user dials the representative telephone number of the nearest remote monitoring center using the telephone (mobile phone) at hand, or operates the intercom in the elevator car, a transmission signal is output to the remote monitoring center. [0004] In this system, the order is assigned to each telephone set in the remote m...

Problems solved by technology

[0005] However, in the event of an earthquake or power outage, as a result of an increase in the transmission signal from the user's telephone, if all the telephones in the remote monitoring center are in communication, the communication will be made according to the transmission signal from the user's telephone. Calls to telephones within the remote monitoring center are blocked
