Wetland is one of the most important living environments for human beings.It has huge environmental and ecological benefits.Protecting the wetland ecological environment is an important problem that must be solved urgently.In the process of environmental protection of wetlands,it is necessary to fully grasp the distribution of quality water resources,the law of change,the amount of water,and the relevant indicators of water quality,In particular,relevant parameters of water quality are very important indicators in the wetland environment.Only by accurately monitoring the water quality parameters in real time,can we reasonably develop and utilize wetland water resources.Therefore,this subject takes the automatic monitoring equipment as the core,builds a wetland remote monitoring system,and effectively analyzes the various water quality parameters of the wetland.The wetland ecological environment remote monitoring system adopts a combination of an upper computer and a lower computer to realize the design of the entire system.The lower unit is mainly composed of a controller and a water quality analyzer.The controller is a Siemens S7-200 PLC.The water quality analyzer uses a five-parameter analyzer,an ammonia nitrogen analyzer,and a permanganate index analyzer manufactured.The Special water quality measuring instruments by HACH Company.The system upper computer is divided into two parts: the monitoring center station platform and the substation system.The substation adopts the combination of Siemens touch screen and WINCC software.The monitoring center platform adopts the independent intellectual property remote water quality automatic monitoring system software launched by the project investment party Fuzhou Fuguang Water Technology Co.,Ltd.For some parameters of system monitoring,this paper designs a fuzzy self-tuning PID algorithm on the control algorithm.At the same time,in view of the remote location of the on-site monitoring stations and the decentralized overall layout,the system adopts GPRS wireless communication and selects the MD 720-30 wireless data communication module to implement distributed remote wireless monitoring of the system.Through the researchand analysis of the GPRS communication,the TCP/IP protocol for the system was designed,and the data transmitted in the system was uniformly encapsulated,and the GPRS communication between the on-site monitoring station and the monitoring center was successfully realized.Finally,the whole system is debugged,the on-site monitoring station runs stably,the monitoring center can accurately monitor the data information of the on-site control station,and can effectively control the on-site monitoring station.
