摘要
为提高传统水质污染监测系统的时效性和易操作性,结合无线传感器技术,设计一种基于无线传感器网络的水质监测系统。首先,根据系统需求,对水质监测系统的整体框架进行构建。然后分别对硬件和软件两个方面进行详细设计,其中硬件设计主要从ZigBee模块最小系统、水质参数采集模块、ZigBee/GPRS网关的接口三个模块进行设计和实现;软件设计则从网络协调器、路由节点和传感器节点三个模块进行设计。最后通过搭建系统软硬件平台,并对系统模块进行串口通信和节点组网实验,以及系统整体性能进行测试。结果表明,本文设计的水质污染检测系统可在2分钟内完成对温度、PH值和电导率的测量,且测试值与实际值误差较小,具备良好的实时性和可靠性。
In order to improve the timeliness and ease of the traditional water quality pollution monitoring system, a water quality monitoring system is designed based on the wireless sensor network.First, the overall framework of the water quality monitoring system is constructed according to the system requirements.For hardware and software, the hardware design is mainly designed from three modules: ZigBee module minimum system, water quality parameter acquisition module, and the interface of ZigBee/GPRS gateway;the software design is designed from the network coordinator, routing node and sensor node.Finally, it builds the system software and software platform, conducts serial port communication and node networking experiments, and tests the overall performance of the system.The results show that the water quality pollution detection system designed here can measure temperature, P H and conductivity within 2 minutes, and the error of test value and actual value has good real-time and reliability.
