Alarming call device for elevator

Abstract

The invention discloses an alarming call device for an elevator. The device comprises a passenger call device, a maintenance call device, a call conversion device and an alarm processing device. The passenger call device arranged in an elevator cage and the maintenance call device arranged in an elevator machine room or a maintenance area can be used for realizing a voice call between person in the elevator cage and person in the machine room or the maintenance area. The alarm processing device arranged in the elevator cage at least comprises an alarm triggering device and an alarm stopping triggering device, and can be used for the person in the elevator cage to give an alarm and stop the alarm. An alarm signal and an alarm stopping signal are transmitted by the alarm processing device through a voice transmission path between the passenger call device and the maintenance call device, and are remotely transmitted through a communication network by the call conversion device. Voices and elevator alarm signals can be simultaneously transmitted.

Description

technical field [0001] The invention relates to an elevator alarm communication device. Background technique [0002] At present, the configuration of the elevator communication device in the prior art is as follows: figure 1 shown. The elevator is generally equipped with a passenger communication device in the car, a maintenance communication device is installed in the machine room, a call trigger device is installed on the maintenance communication device, and the alarm trigger device is connected to the passenger communication device. Elevator passengers can communicate between the passenger communication device and the maintenance communication device by pressing the alarm trigger device, and the personnel in the machine room can also call the passenger communication device through the call trigger device on the maintenance communication device to realize the communication between the maintenance communication device and passengers Calls between devices. There are fol...

AI Technical Summary

Problems solved by technology

There are following deficiencies in this elevator internal communication device: 1. After the elevator has a trapped person alarm, the communication device can only realize the voice communication after the alarm, and cannot realize the alarm signal transmission and indication; The stage of the process is not clear, and it is easy to make the trapped people feel anxious or implement behaviors that endanger personal safety
