摘　　要：用现代化科技手段改善农民饮水质量,助推规模化和智能化供水工程建设,是乡村振兴的重要内容之一。目前,部分乡村地区的移动基站还不能达到无死角、全覆盖,以致无线通信技术不能在远程遥控遥测中充分发挥作用。通过基于NB-IoT与LoRa相结合的方式,互补公共移动网络与自主无线网络,改善乡村集中供水中数据采集的通信质量。利用STM32微型控制器完成乡村供水系统中水源井各压力、流量等数据采集并传输,提高了远程分布汲水、集中供水的效率,并为乡村供水工程提供了典型解决方案。At present,the mobile base station in some rural areas can not reach the full coverage,which makes the wireless communication technology can not play a full role in remote control and telemetry.By the combination of NB-IoT and LoRa,the advantages and disadvantages of public mobile network and self-built wireless network are complementary to improve the communication quality of data collection in rural centralized water supply.STM32 microcontroller is used to collect and transmit data such as pressure and flow of water source well in rural water supply system,which improves the efficiency of remote distribution and centralized water supply,and provides a typical solution for rural water supply project.
