摘要： 粮食安全是重大民生问题,对粮情的检测意义重大。为了解决有线通信布线困难、不易于扩展问题,采用LoRa无线通信技术、嵌入式技术以及软件开发技术,设计了一套基于LoRa的粮情远程监控系统。STM32作为采集模块的核心模块,利用LoRa无线网络,将采集到的温湿度数据上传至上位机端,采用Delphi语言进行开发上位机监控软件,实现对数据的显示、存储和分析。通过实际运行证明,系统稳定可靠,操作简单,能够实时采集多点温湿度信息,满足了对粮库粮情监测要求。

Abstract: Food security is a major livelihood issue, and the detection of grain situation is of great significance. In order to solve the problem that wired communication is difficult to wire and expand, a remote monitoring system of grain situation based on LoRa was designed by using LoRa wireless communication technology, embedded technology and software development technology. STM32, as the core module of the acquisition module, uses LoRa wireless network to upload the collected temperature and humidity data to the upper computer, and uses Delphi language to develop the monitoring software of the upper computer, so as to display, store and analyze the data. The actual operation proves that the system is stable, reliable, simple to operate, capable of collecting multi-point temperature and humidity information in real time, which can meet the requirements of grain situation monitoring in grain depots.

Key words: LoRa, telecommunication, monitoring system
