基于LoRa的水泵智能控制系统设计与实现

为实现水泵自动控制及泵站智能调度,进而达到泵房无人值守运行、提高供水保障能力的目的,提出了一种结合物联网技术、边缘计算技术、嵌入式技术及数据可视化技术的水泵智能控制系统构架。该系统采用LoRa低功耗物联网技术配合STM32F103微处理器构建网络节点及数据网关,使用C#编写后台管理平台和Django搭建数据展示平台;针对泵房工作环境特点综合考虑了系统的成本、可靠性、扩展性等。通过该系统的设计与实验,能够培养学生的团队合作意识,促使学生综合运用电子线路设计、物联网、嵌入式开发、.NET程序设计等知识。该系统的部署及运用在保障学校供水安全的同时,也为学生提高实践动手能力提供了真实的物联网系统运维环境及原始数据。

Design and realization of pump intelligent control system based on LoRa

In order to realize the intelligent dispatching of automatic control of the water pump and the unattended operation of the pump house,and improve the ability of water supply,an intelligent control system framework of the water pump is proposed,which combines Internet of things technology,edge computing technology,embedded technology and data visualization technology.This system uses LoRa low-power Internet of things technology and STM32F103 microprocessor to build network nodes and data gateway and uses C#programming for the background management platform and Django data display platform.According to the characteristics of the pump room working environment,the cost,reliability and expansibility of the system are comprehensively considered.Through the design and experiment of the system,students'sense of teamwork can be cultivated,and the knowledge of electronic circuit design,Internet of things,embedded development,and.Net programming can be used synthetically.The deployment and application of the system not only ensure the safety of university water supply,but also provide the real operation and maintenance environment and original data of the Internet of things system for students to improve their practical ability.
