摘　　要：针对山体滑坡灾害监测系统存在的功耗高、环境适应性差、大范围数据通信困难等问题,文中结合物联网技术和嵌入式技术,提出一种基于LoRa技术的滑坡监测系统。该系统使用SX1278射频芯片设置LoRa收发器,配合STM32L071RBT6微处理器构建终端节点和网关节点,并完成无线传感器自组网及对滑坡灾害监测数据的实时采集、传输。软件采用嵌入式实时多线程操作系统来实现多任务调度机制,可保证系统的并发式多参数采集并有效控制系统功耗;后台上位机软件可实现对所有监测数据的实时显示、历史查询、数据分析和决策控制等功能,用户支持PC机网页端或手机客户端访问。经野外测试得出,文中系统具有功耗低、自组网、通信稳定可靠及传输距离远等技术特点,可以有效满足野外恶劣环境下山体滑坡监测的需求。As the mountain landslide disaster monitoring system has some problems such as high power consumption,poor environmental adaptability and difficulty in large-scale data communication,a landslide monitoring system based on LoRa technology is designed in combination with IoT technology and embedded technology. In this system, the SX1278 radio frequency chip is used to set the LoRa transceiver,and cooperate with STM32L071RBT6 microprocessor to build terminal nodes and gateway nodes,so as to complete the wireless sensor Ad Hoc network and real-time collection and transmission of landslide disaster monitoring data. The embedded real-time multi-threaded operating system is used in the software to realize the multi-task scheduling mechanism,which can ensure the concurrent multi-parameter collection of the system and effectively control the power consumption of the system. The background upper-computer software can realize the functions of real-time display,historical query,data analysis and decision control of all monitored data,and support users’ access to PC webpage or mobile client-side. The field testing results show that the system has the technical characteristics of low power consumption,Ad Hoc network, stable and reliable communication and remote transmission, which can effectively meet the needs of mountain landslide monitoring in the harsh environment.
