Design of Landslide Remote Monitoring System Based on LoRa Technology

滑坡状态的实时监测是灾害预防与治理的重要依据.针对目前滑坡监测系统中存在测点间距离远、多传感器接入繁琐、数据采集困难等问题,设计了一种基于LoRa的滑坡远程监测系统.该系统包括节点单元、LoRa集中器、云服务器及滑坡信息监测网页.采用STM32单片机设计的节点单元,完成对滑坡现场各种传感器数据的采集和协议转换;待LoRa集中器将数据汇聚后通过4G通信发送到云服务器;开发滑坡信息监测网页,实时刷新监测结果并保存历史数据.实验表明,该系统可实现多参数远程无线监测,且具有功耗低、组网方便、可网页显示等特点.

The real-time monitoring of landslide status is an important basis for disaster prevention and management. A LoRa-based landslide remote monitoring system is designed for the problems of long distance between measurement points, cumbersome access to multiple sensors and difficult data collection in the current landslide monitoring system. The system includes node unit, LoRa concentrator, cloud server and web page of landslide information monitoring. Firstly, A node unit designed with STM32 microcontroller is adopted to complete the acquisition and protocol conversion of various sensor data from the landslide site. The data is sent to the cloud server via 4 G communication after the LoRa concentrator aggregates them,. The web page of landslide information monitoring is developed to refresh the monitoring results and save the historical data in real time. The experiments show that the system can realize the multi-parameter remote wireless monitoring, and has the features of low power consumption, convenient networking and web page display.
