中文摘要:
结合传感器、ARM、无线通信、服务器等物联网技术，设计了一套微型水质监测系统，监测被处理过的家庭废水能否进行二次利用，保证二次利用的水质能够达到城市污水再生利用标准。基于智能化、微型化的设计目标，阐述了由控制器到本地网关再到移动终端的总体设计方案；重点给出了基于水质传感器、STM32微控制器和WiFi无线模块的硬件设计与STM32软件设计思路及实现方法；制订了各部分之间的通信协议。测试结果表明，系统硬件、软件设计方案可行，运行稳定，完成了水质实时监测、进出水自动控制、二次利用水量统计以及移动端在线显示的功能。本系统实时性好、实用性强，可投入未来家庭使用，推动智慧家庭的发展，也可以应用于水产养殖厂和泳池的水环境监测。
英文摘要:
A set of miniature water quality monitoring system was designed based on theInternet of things(IOT) technology such as sensor,ARM,wireless communicationand server,to monitor whether the treated domestic wastewater can be reused andmeet the standard on the reuse of urban recycling water.According to theintelligentized and miniaturized design goals,the overall design scheme fromthe controller to local gateway and then to mobile terminal was expounded.Thehardware circuit design scheme based on water quality sensor,STM32 microcontroller and WiFi wireless module and STM32 software design ideas andimplementation methods were described.Moreover,the communication protocol amongthe various parts was given.The test results show that the system software andhardware designs are reliable,and the functions can be realized includingreal-time monitoring of water quality,automatic control of inlet and outletwater,statistics of secondary water utilization and online display.The systemis real-time and practical,and can be put into future family use,to promote thedevelopment of intelligent home.It can also be used for aquaculture andswimming pool water quality monitoring.
