摘要
根据集中供热系统数据采集的特点,介绍了基于GPRS-Internet网络的换热站无线远程监控系统的组成以及换热站的自动控制。远程换热站采集现场的温度、流量、压力等数据,并通过GPRS-Internet网络传送到监控中心。监控中心实现了对整个供热系统进行远程自动化控制,解决了整个供热系统热工参数难以采集和热量分配不均等问题。运行结果表明,该系统稳定性好、调节精度高、操作方便,可以满足远程监控和长周期稳定运行等要求。
In accordance with the features of data collection in centralized heating system, the composition and automatic control of the wireless remote monitoring system based on GPRS-Internet that is used in heat-exchange station are introduced. The data of temperature, flow, and pressure, etc. , are collected in remote heat-exchange station, and transmitted into monitoring center threugh GPRS-Internet. The remote automatic control for the whole heating system is implemented in the monitoring center; and the problems of the difficulty to collect thermal parameters for the whole system and the unevenness of heat distribution are solved. The result of operation indicates that the system is stable, and offers high regulating accuracy and easy operation. The design meets the requirements of long-term stable operation of remote monitoring.
