基于ZigBee网络的电厂循环水在线监测系统设计

目前,火电厂循环水水质监测主要是离线方式,在人工采样测量参数之后,对相关设备进行调整操作。缺点是测量工作量大,调节精度不够而且不及时,导致参数不能维持在稳定的范围内。该文通过ZigBee技术和树莓派(Raspberry Pi)构建循环水在线监测系统,实现实时动态地将数据传送至在线监测平台,使水质参数测量更具客观性和科学性,为设备调整的控制决策提供准确的依据。

Design of power plant circulating water on-line monitoring system based on ZigBee network

At present,the monitor of the circulating water in thermal power plant is mainly by off-line,the equipment is adjusted based on parameters that measuring by artificial sampling.The disadvantages of off-line are that the work of measurement is too much,the precision of adjustment is not enough and not in time,the parameter can not be maintained in a stable range.In this paper,by using the techniques of ZigBee and Raspberry Pi,design an on-line monitor system of circulating water,it can send the data to the monitoring platform and make the water parameters more objective and scientific,then provide accurate basis for the control decision of equipment.
