基于LoRa和GPRS的滑坡监测数据传输系统

Landslide Monitoring Data Transmission System based on LoRa and GPRS

针对滑坡等复杂环境下参考站和流动站之间数据易缺失等问题,设计了一种基于LoRa和GPRS的数据传输系统。滑坡监测的方法很多,目前主要采用监测精度很高的GPS滑坡监测方法。GPS滑坡监测系统主要由参考站和流动站组成。参考站通过Lo Ra模块发送差分信息给与流动站相连的LoRa模块,在流动站GPS测姿仪上再连接一个GPRS模块,然后编程实现差分信息的解算,并将解算后的数据通过GPRS模块发送到服务器。测试结果显示,该系统运行稳定,误码率低。

Aiming at the problem of easy data loss between reference station and rover in complex environment such as landslide,a data transmission system based on LoRa and GPRS is designed.There are many methods for landslide monitoring.At present,GPS landslide monitoring methods with high monitoring accuracy are mainly used.The GPS landslide monitoring system mainly consists of reference stations and rover stations.The reference station sends differential information to the LoRa module connected to the rover through the LoRa module,a GPRS module is connected to the GPS station of the rover,and then the solution of the differential information is programmed and the solved data is sent to the server through the GPRS module.The test results indicate that the system is stable and the bit error rate is low.
