输电线路分布式故障定位设备是一种安装在输电线路沿线多个监测点（输电线路上或者杆塔上）的智能监测系统。其核心原理是行波测距法，通过精确测量故障产生的暂态行波信号到达不同监测点的时间差来实现精确定位。

In the criss - cross railway and urban rail transit networks in our country, tens of thousands of slopes, like silent guardians, maintain the safety and smooth operation of the rail lines. However, under the long - term effects of natural weathering, rainwater erosion, train vibrations, and extreme weather, these slopes may deform, slide, or even collapse, seriously threatening the safety of train operations.

Mountain torrents are characterized by sudden onset, rapid disaster formation, and great destructive power, and are the main natural disasters in mountainous areas. This article focuses on the "last mile" problem of small - watershed mountain torrent early warning, and details how the solar - powered IoT monitoring system can break through the monitoring bottleneck in areas without electricity and network through ......

Avalanches, known as the "white death", are a worldwide challenge to predict. This article focuses on the extreme environmental challenges of alpine avalanche early warning and elaborates on how the solar-powered Internet of Things monitoring system can deploy a multi-parameter sensor network that is resistant to extreme cold and self-powered to monitor the key physical indicators of the snowpack in real time......

Geological disasters are silent, but technology can detect them. This article deeply explores the challenges of concealment and suddenness of slope collapses, systematically analyzes how the solar-powered Internet of Things monitoring ...
