Research On The Elevator Remote Monitoring System On GPRS

With rapid development of automatic control and network techniques, network-based remote monitoring, maintenance and intelligent fault diagnosis is becoming an investigating hotspot in the elevator industry. This thesis is researching on the system of elevator remote monitor, based on GPRS, integrates of traditional computer, modern Internet, GPRS and DSP technology. It has many merits, such a multiple functions, low cost, well real time capability and high reliability. It is also convenient to operate, easy to install, maintain and upgrade.After analyzing present researches and comparing the current means on remote wireless monitoring systems of elevators, integrating traditional modal of remote monitoring system, we advance the system of elevator remote monitoring based on GPRS. Then it introduces the GPRS structure of network and basic theories, and compares with other manners of data transmission, put forward the merit of GPRS on the remote monitor system.This thesis designs and develops the scheme of elevator remote monitoring system based on GPRS in detail, emphases on system structure, system constitutes and system work process, and also explains the system constitutes'function and design details. Then it narrates the design of software process to client and center monitor, and introduces the detail of function module development and database design. Finally it provides the software interface.Finally, this text introduces characteristic of the system, and gives prospect of the next work.
