摘　　要：为杜绝农村偏远地区水资源的浪费现象,保障管理部门对用水情况的有效监管,同时考虑到偏远地区财政支出有限的情况,提供一种实时监测居民用水并方便购水的远传抄表终端方案。该终端以国产华大半导体器件HC32L19X系列为控制核心,硬件由微控制器电路、数据存储模块、LoRa下行抄表模块、蓝牙手机通信模块、Cat.1上行通信模块等组成。该终端可以实时将下行水表数据抄读到终端存储器中,并根据上行通信的通信协议,通过Cat.1网络基站传输到自来水公司的数据管理平台上,实现对用户数据的管理,并可实现用户在线缴费功能。通过测试验证,此网关终端在实现用户用水情况监管的同时,降低了当地管理部门的资金投入,具有很好的实用价值。In order to reduce the waste of water resources in remote rural areas, ensure the effective supervision of water usage by management departments, and take into account the limited financial expenditure in remote areas, a remote meter reading terminal scheme is provided to monitor residents’ water usage in real time and facilitate to purchase water. The terminal takes the domestic Huada semiconductor device HC32l19X series as the control core, and the hardware includes microcontroller circuit, data storage module, Lora downlink meter reading module, Bluetooth mobile phone communication module and Cat.1. It is composed of uplink communication module and other circuits. The terminal can read the downlink water meter data into the terminal memory in real time, and transmit the stored data to the data platform of the water management department through the Cat.1 network base station according to the communication protocol of uplink communication, so as to realize the management of user data and the function of online payment. Through test and verification, this gateway terminal not only realizes the supervision of water usage, but also reduces the capital investment of local management departments. It has good practical value.
