Landslide monitoring system for railway disaster prevention

Abstract

The invention discloses a landslide monitoring system for railway disaster prevention. The landslide monitoring system comprises a landslide detection system, a monitoring host system and a landslide sensing system, wherein the landslide sensing system senses landslide change information and transmits the landslide change information to the landslide detection system; the landslide detection system processes and converts the received landslide change information into a sensing signal and transmits the sensing signal to the monitoring host system; and the monitoring host system stores and processes the landslide change information. The landslide monitoring system can perform unmanned real-time monitoring on the landslide change information continuously, and gives an alarm before the changes of a roadbed exceed the safety range to effectively prevent accidents such as rain derail from happening.

Description

Technical field [0001] The invention relates to a landslide monitoring system, in particular to a monitoring system for realizing railway disaster prevention by monitoring landslides by sensors, and belongs to the technical field of disaster prevention and reduction. Background technique [0002] Road and rail transportation undertake most of the transportation tasks on landing. A developed road and rail transportation network is a prerequisite for any country or region to achieve rapid economic development. There are often quite a few natural disasters along highways and railways, such as strong winds, snowfall, floods, earthquakes, fires, rockfalls, and roadbed settlements. Landslides are a kind of geological hazard widely existing along highways and railways. It is a kind of geological change caused by special geological structure, which often causes secondary geological disasters. [0003] Landslide monitoring is to predict the trend of landslides through various technical me...

Problems solved by technology

[0004] At present, among the technical methods used for landslide monitoring, manual measurement technology not only has a low degree of automation, but also has too much labor, and it is difficult to achieve long-term real-time measurement

The existing main monitoring technologies are described as follows: (1) Image recognition technology, although it solves the problem of real-time dynamic monitoring, the accuracy of intelligent image recognition decreases under severe weather conditions such as rain, snow, fog, and monitoring false alarms occur from time to time. Even in the event of a dangerous situation, it was missed

Replacing intelligent image recognition with artificial observation images is only a short-term expedient measure. 24-hour uninterrupted observation is difficult to last. In addition, the high cost of the image monitoring system also makes it difficult for this technology to be widely used; (2) Pull wire displacement monitoring, the theory of this method It is simple in appearance, but limited by the geographical environment, the cable monitoring project in mountainous areas where landslides are prone to occur is large and extremely difficult, and there are potential safety hazards, and it is also extremely difficult to apply in practice; In order to realize the monitoring of landslides, it is necessary to achieve the accuracy of GPS positioning within 1 meter. Such accuracy requires at least two base station GPS joint assistance for real-time dynamic monitoring, which is expensive and difficult to achieve; (4) Inclination monitoring technology, this technology is The trend of landslides can be predicted by monitoring changes in ground inclination. However, when many landslides occur, ground translation and subsidence first occur, and ground inclination does not necessarily occur. Therefore, the inclination monitoring technology has great limitations.

In addition, these existing monitoring technologies need to solve the problem of power supply first. In mountainous areas where landslides are prone to occur, it is almost impossible to provide power supply for monitoring landslides.
