The Design Of Remote Monitoring System For Elevators Based On GPRS

With the development of modern cities, residential area, shops, office blocks with high buildings spring up like mushroom, it has become an indispensable vertical vehicle for urban people. So the safety of its operation becomes a very important subject in modern society. At the same time, with the development and improvement of network technology, computer technology, technology of automatic control, communication, technology as well as technology of geographic information, the realization of many integrated functions such as remote control,maintenance,faults-diagnosing,the display of elevators' situation and operation become an hot problem to handle in elevator industry at home and abroad. With C++ Builder6.0 development vehicle, the remote monitoring of elevators based on GPRS was realized by using MapObjects componenttechnology.In this paper, the recent research situation of remote monitoring of elevators athome and abroad was analyzed in brief at first, mainly focusing on analyzing and comparing the performance,price,reliability of monitoring manners of monitoring system, and then the remote monitoring system based on GPRS was put forth.Then, the network structure and principle of GPRS were introduced briefly. Subsequently, it introduces how to realize the remote monitoring of elevators using Socket technology in details.By using MapObjects component technology, It realizes the real-time display of elevators' location, basic operation situation, and related functions of electron map including the map enlarging, reducing a pleasure trip, displaying of location and so on.The main body of this paper has perfectly got up with system thought,Socket technology,GIS (Geographic Information System) technology based on MapObjects component. It realizes remote monitoring system which integrates remote communication of elevators,the display of location and operation situation of elevators.The software of the remote monitoring system of elevators has many merits such as high real time capability,low cost,high reliability, and has well application.
