摘　　要：随着经济水平提高及人们对美好生活的向往,越来越多人追求健康饮水。针对小区自助售水机滤芯及设备没有及时更换或清洗导致的的水质安全问题,设计了一款基于NB-IoT窄带物联网的小区直饮水质监测系统。对系统框架结构进行了总体分析,并对系统相关软硬件模块进行了介绍。硬件设计方面主要包括STM32主控芯片、水质检测模块、NB-IoT物联网模块及电源模块等。软件部分包括OneNET云平台和小程序客户端等。对系统实测结果表明,基于NB-IoT小区直饮水质监测系统能够较好的对温度、PH值、浑浊度、TDS等水质参数检测,并通过物联网模块将数据发送到工作人员和用户手机端,减小了直饮水监测人力成本,提高了直饮水的安全性。With the improvement of economic level and people’s yearning for a better life, more and more people pursue the healthy drinking water.Aiming at the water quality safety problems caused by the filter element and equipment of self-service water vending machine in the community are not replaced or cleaned in time, a community direct drinking water quality monitoring system based on NB-IoT narrowband Internet of things is designed. The overall structure of the system framework is analyzed, and the related software and hardware modules of the system are introduced. Hardware design mainly includes STM32 main control chip, water quality detection module, NB-IoT Internet of things module and power module. The software part includes onenet cloud platform and applet client. The measured results of the system show that the direct drinking water quality monitoring system based on NB-IoT community can better detect the water quality parameters such as temperature, pH value, turbidity and TDS, and send the data to the staff and users' mobile phones through the Internet of things module, which reduces the human cost of direct drinking water monitoring and improves the safety of direct drinking water.
