Elevator monitoring system based on wireless network

Abstract

The invention discloses an elevator monitoring system based on wireless network, comprising a lift car data collector, a control data collector, a CAN interface and a monitoring terminal, wherein a sensor group is connected with a second microprocessor in series to form the lift car data collector; the second microprocessor is electrically connected with the CAN interface; the control data collector comprises an ID card recognizer, a GSM module, a first microprocessor, a login calling panel and an elevator control system, wherein the ID card recognizer, the GSM module and an output end of thelogin calling panel are connected with an input end of the first microprocessor respectively; the first microprocessor is electrically connected with the CAN interface and the elevator control systemrespectively; and the GSM module is wirelessly connected with the monitoring terminal. The elevator monitoring system based on wireless network has the advantages of simple configuration, low cost andquick response speed on elevator fault, and the data transmission of the system is convenient, intact, reliable and safe, with wide application scope.

Description

technical field [0001] The invention relates to the technical field of a wireless network-based elevator supervision system. Background technique [0002] The safe use and scientific management of elevators are of great importance, which is directly related to the safety of people's lives and property. In the modern intelligent buildings of some developed countries in the world, people have classified the elevator as an important controlled device of the building automation management system, and adopted advanced weak current monitoring methods to realize all-round monitoring of the elevator's operating status, maintenance, and safety protection. management. [0003] According to relevant statistics, the total number of elevators in use in my country is more than 800,000, but most of them have not been equipped with elevator remote monitoring systems. Once the elevator breaks down, the only way to ask for help is through the car intercom, otherwise the only way to leave th...

AI Technical Summary

Problems solved by technology

The system has defects such as high cost (high equipment investment cost, high operating cost), complex configuration, and frequent monitoring disconnection

Remote monitoring of the elevator is not possible if no internet or telephone lines are reserved in the building

In addition, in the existing elevator remote monitoring system, only the supervisory personnel can find that the elevator has broken down from the terminal computer of the monitoring center, and then the supervisory personnel will notify the maintenance personnel to repair the elevator by other means; Human monitoring, will not be able to respond to the alarm

[0005] Moreover, most monitoring systems can only be aimed at the elevator control system produced by the elevator factory, which has low compatibility and cannot be popularized on a large scale.
