摘　　要：针对江河流域氨氮等水质参数含量超标,传统水质检测方法存在预处理过程复杂、检测设备体积庞大、检测周期长、不能实现连续自动检测等问题,提出采用纳氏试剂分光光度法检测水质参数,并结合西门子PLC、组态软件(MCGS)、4G移动通信等技术,设计出基于物联网的水质在线监测系统。介绍了系统基于C/S模式的总体架构设计,并基于一个感知节点详细阐述了由PLC、MCGS、蠕动泵、分光光度计等组成的检测系统硬件结构设计,并对水质检测软件功能进行了分析,分别对检测系统、PLC控制程序和4G通信程序进行了测试。系统测试结果表明,该系统自动化程度高、检测周期短、能够实现对0 mg/L^300 mg/L范围的样品进行检测,具有实际应用价值。In view of water quality parameters such as ammonia nitrogen in river basin exceeded, traditional methods of water quality monitoring have problems such as complex pretreatment process, large monitoring equipment, long detection period, and failure to achieve continuous automatic detection, an online water quality monitoring system based on the internet of things is designed using Nessler＇s reagent spectrophotometric as parameter detection method, which combined with Siemens PLC, configuration software, 4 C mobile communication and other technologies. The overall architecture based on the C/S model is introduced, for a sensing node, the hardware structure of PLC, MCGS, peristaltic pump and spectrophotometer is described in detail. The function of water quality testing software is analyzed; the testing system, PLC control program and 4G communication program are tested. The final testing results show that the system has a high degree of automation, short detection period, and can be used to detect samples in the range of 0 mg/L -300 mg/L, which has great value on practical
