The design of elevator monitoring terminal Based on the GPRS

摘要

The elevator monitoring system of elevator is an integrated elevator management platform that can realize fault for alarm,rescuing trapped persons,daily management,quality evaluation and preventing hidden trouble by using C8051f060 MCU as the control core to sensor and collect the elevator operation data,with built-in TCP/IP transport protocol and with HuaWei GTM900C GPRS module to realize all kinds of data monitoring of the elevator,and the transmitting of the data to processing server through the network.This paper mainly introduces the formation of wireless monitoring network system and communication protocol construction,and especially analyzes the function and the system architecture of the wireless communication terminal in real-time monitoring.GPRS can not only satisfy the requirement of real-time elevator monitoring system,with low cost and high reliability but can also effectively avoid a variety of problems that are caused by transmitting the alarm data through cables.This system provides many valuable experiences for the development of unattended system,and it has a broad development prospects.
