智能分布式LonWorks水环境监测系统研究

Study of Water Environment Monitoring System with Intelligent and Distributed LonWorks

在探讨了城市水环境监测客观需求的基础上,从结构特点、功能以及实际应用等角度阐述了LonWorks适用于城市水环境监测的技术优点,尤其对神经元芯片的处理单元以及LonTalk通信协议提供的服务及功能作了深入分析,构建了基于LonWorks总线技术的城市水环境监测系统,对各部分的功能和作用进行了详述,重点对测量池节点设计、现场控制层结构、iLon100服务器配置等作了研究和论述,介绍了系统执行智能分布式实时监测、控制的工作流程和功能。

In this paper,the status of city water environment monitoring in home and abroad is briefly introduced.On the basis of discussing the monitoring request,it was described that the technique advantage of LonWorks adapted to monitoring system,from the aspect of frame,function and application.Especially,the processor of neuro chip,application I/O port,memory mirror and service of LonTalk protocol was analyzed.Then,we presented the monitoring system based on LonWorks,and accounted for the function and procedure of each section. A detailed study of the measure container, frame of local control layer and configuration of iLon100 server has been carried out. At last, we put forward the problems which are worth researching further.
