摘　　要：为保证水资源的合理利用和有效监管,减少农村偏远地区水资源的浪费,克服偏远地区基站少、信号弱的实际情况,文中提出一种实时监测居民用水并方便购水的水表装置。该装置以国产华大半导体器件HC32L17X系列为控制核心,硬件包括微控制器电路、计量信号采集模块、阀门控制电路、通信接口电路等,软件包括水量计量单元、阀门控制单元、NB-IoT通信单元、蓝牙通信单元、红外通信单元等功能模块。水表装置在基站信号稳定的片区,通过NB-IoT通信方式将用水数据上传到数据平台,实现实时监测管网用户的用水信息功能;在信号不稳定的区域,通过短距离通信设备蓝牙或红外方式来获取用户的用水信息,实现用户在线缴费的功能。测试结果表明,所提出的水表装置可以克服农村偏远地区信号弱的情况,通信成功率高,具有一定的实用价值。In order to ensure the rational utilization and effective supervision of water resources,reduce the waste of water resources in remote rural areas,and deal with the objective situation of few base stations and weak signals in remote areas,a water meter device for real-time monitoring of household water consumption and convenient water purchase is proposed. In this device,the SCMs in HC32l17X series made by Huada Semiconductor Co.,Ltd. is taken as the control core. Its hardware includes microcontroller circuit,metering signal acquisition module,valve control circuit,communication interface circuit,etc.Its software includes water metering unit,valve control unit,NB-IoT communication unit,Bluetooth communication unit,infrared communication unit and other functional modules. In the area where the base station signal is stable,the water meter device uploads the water-consumption data to the data platform by means of NB-IoT communication mode to monitor the waterconsumption information of pipe network users in real time;in the area where the signal is unstable,the device obtains the household water-consumption information by means of Bluetooth or infrared mode of short-range communication equipment,so as to realize the online payment of users. The testing results show that the proposed water meter device can deal with the situation of weak signal in remote rural areas,and has high success rate of communication and a certain practical value.
