基于传感器的边坡灾害监测系统研究

Research on Slope Disaster Monitoring System Based on Sensor

为了减少边坡灾害的发生,本研究基于分布式传感器开发出一个边坡灾害监测系统。传感器节点具有无线通信和倾斜检测的功能。每个传感器节点可以与其他节点进行通信,并将修正后的数据发送到基站,该基站可在紧急情况下向管理员发送警报消息。本研究开发的边坡灾害监测系统已安装在甘肃某铁路沿线的一个边坡上,并进行了为期8个月的性能评估试验。通过现场试验研究发现,所开发的传感器网络系统能够有效地检测出边坡灾害。但在该系统启动阶段,系统中节点的几何布置可能会导致需要较长的时间来建立稳定的网络连接。因此,如何快速布置边坡灾害监测系统中传感器仍须进一步研究。

In order to reduce the occurrence of slope disasters,a slope disaster monitoring system based on distributed sensors is developed in this study.The sensor node has wireless communication and tilt detec⁃tion functions.Each sensor node can communicate with other nodes and send the corrected data to the base station,which can send alarm messages to the administrator in case of emergency.The developed in this study slope disaster monitoring system has been installed on a slope along a railway in Gansu prov⁃ince,and the performance evaluation test has been carried out for 8 months.The field test shows that the sensor network system can detect slope disaster effectively.However,during the system startup phase,the geometry of the nodes in the system may lead to a longer time to establish a stable network connection.Therefore,the sensor layout in slope disaster monitoring system still needs further research.
