The Design Of The Data Transmission System About Elevator Based On ARM And GPRS

With the development of the modern city, urban high-rise buildings, such as alarge number of commercial office buildings, commercial buildings, residentialquarters, and elevator become essential in the high-rise building vertical transport.Therefore, the safe operation of the lift to become a very important research topic inmodern social development. With the continuous development and progress of theautomatic control technology, computer technology, network technology,communication technology, and geographic information technologies, through anetwork of elevator remote monitoring, maintenance, on-site troubleshooting andremote elevator position, the real-time display of the state has been become one of theproblems of the elevator industry research at home and abroad.With the continuous development of the remote data transmission technology,wireless communication technology based on GPRS network gradually been widelyused. This article combines embedded technology, mobile communication technology,Internet technology, based embedded with GPRS elevator remote data transmission,designed a holistic, low-cost, reliable solution.This paper describes the research purpose and significance of the elevator datatransmission system, home and abroad elevator remote monitoring system data transferstatus and development made in this article.Secondly, details the basic structure and working principle of the GPRS network,and then from the hardware design of the system software design, and analysis.SAMSUNG S3C2440A ARM920T core-based embedded processing chip, theprocessor interface resource-rich, scalable ability selection in this article, has a largeadvantage in the future to further improve. GPRS module selected SIMENS MC39imodule, the module embedded TCP/IP protocol support AT command, a greatadvantage for secondary development.The final design of the PC monitoring system, using Visual C++object-orientedprogramming ideas, use of the windows socket modular programming complete PC software design, data transmission and the next crew.The design is based on high reliability embedded with GPRS remote elevatormonitoring system, real-time communications and strong, low operating costs, theactual application effect.
