基于LoRa技术的小区垃圾桶监测系统设计

Design of Community Trash Can System Based on LoRa Technology

住宅小区内的垃圾桶由于分布散落而难以系统管理,因此设计了一种基于LoRa技术的垃圾桶远程监测系统。本文在系统网络构建的基础上完成了方案的总体设计:硬件部分以STM32系列微控制芯片为核心,利用温度传感器和超声波传感器获取垃圾桶的温度及满溢状态,并通过基于LoRa技术搭建的网络实现与监控中心之间的通信;软件部分使用μC/OS-II操作系统来确保系统的实时性。测试结果表明,系统功能良好,通信稳定,能有效提高住宅小区内垃圾管理的工作效率。

Trash cans in residential areas are difficult to manage due to their scattered distribution.Therefore,a trash can remote monitoring system based on Long Range(LoRa)technology is designed.In this paper,the overall design of the scheme is completed on the basis of the system network construction.The hardware part takes STM32 series micro-control chip as the core,uses temperature sensor and ultrasonic sensor to obtain the temperature and overflow status of the trash can,and realizes the communication with the monitoring center through the network built based on LoRa technology.The software part usesμC/OS-II operating system to ensure the real-time performance of the system.The test results show that the system has good function,stable communication and can effectively improve the work efficiency of garbage management in residential quarters.
