| 摘 要： | 设计一套铁路路基沉降数据自动化采集系统，采用静力水准仪作为铁路路基沉降数据的采集单元，利用LoRa无线通信技术，选用低功耗STM8系列单片机和SX1278收发器，在IAR环境下移植Contiki操作系统及其自带的Rime协议栈，完成Mesh网络的多跳传输。将采集到的铁路路基沉降数据形成可视化监测界面,实现现有铁路路基沉降数据远距离、低功耗、可靠的无线传输。

| Abstract: | We design an automatic collection system of railway roadbed subsidence data. The system adopts static force level gage as the collection unit of railway roadbed subsidence data. Using LoRa wireless communication technology, and a low power STM8 series single chip and SX1278 RF transceiver, the Contiki operating system and its own Rime protocol stack are transplanted in the IAR environment to complete the multi-hop transmission of Mesh network. The collected railway subgrade settlement data is formed into a visual monitoring interface to realize the remote, low power consumption and reliable wireless transmission of the existing railway subgrade settlement data. |
