Abstract
With rapid development of automatic control work techniques, network-based
remote monitoring, maintenance and intelligent fault diagnosis is ing an
investigating hotspot in the elevator industry. This thesis is researching on the system of
elevator remote monitor, based on GPRS, integrates of puter, modern
, 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 paring 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 work and basic theories, pares
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.
