Elevator incident early-warning emergency support system

Abstract

The invention discloses an elevator incident early-warning emergency support system which comprises an elevator intelligent internet-of-thing terminal and an RFID (radiofrequency identification device) maintenance and management system. The RFID maintenance and management system consists of an RFID reading and writing module, an input module, a display module and a communication module, the elevator intelligent internet-of-thing terminal comprises a CPU (central processing unit), a GSM (global system for mobile communications) / GPRS (general packet radio service) / CDMA (code division multiple access) module, a speech circuit module, an audio power amplifier module, an audio switching circuit module and a switching network module, the CPU is respectively connected with the GSM / GPRS / CDMA module, the speech circuit module and the switching network module, the GSM / GPRS / CDMA module and the speech circuit module are connected with the audio power amplifier circuit module, the switching network module is connected with the audio switching circuit module, and the CPU is respectively connected with the RFID reading and writing module, the input module, the display module and the communication module. By the aid of the elevator incident early-warning emergency support system, an elevator is intelligently maintained and managed, warning for elevator incidents can be realized at the earliest, and safety running of the elevator is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and relates to an elevator emergency early warning and emergency support system. Background technique [0002] With the development of social economy and culture, the elevator, an indispensable vertical transportation tool for modern people's life, has become increasingly popular. Elevators are closely related to the improvement of people's living conditions and the improvement of people's space life quality. However, it happens from time to time that the elevator breaks down or the power failure causes passengers to be trapped. Therefore, when passengers are trapped in the elevator, how to get in touch with the outside world to obtain rescue becomes particularly important. Generally speaking, passengers can get in touch with the outside world through several channels: 1. Some elevator cars are equipped with telephones, and passengers can call for help from relatives and friends ...

AI Technical Summary

Problems solved by technology

[0006] 2. The function of multi-party communication cannot be realized, such as direct communication between the car and the property department, maintenance unit, maintenance engineer, etc.;

[0007] 3. Due to the strong interference inside the elevator, generally speaking, the call quality of the emergency call system provided by the elevator is not very good;

[0008] 4. If there is a problem with the call system, it will be very troublesome to maintain, so many elevators have completely become decorations after the problem with the call system

At present, the three-party or five-party call in the elevator adopts a wired method, and a special person is required to be on duty; the remote monitoring also uses a wired Modem, the system cost is high, and the system expansion is difficult
