Geographical skin

Abstract

The invention relates to a geographic skin, which is composed of at least one prefabricated member, and is laid on a geographic surface needing to be detected and monitored, and the prefabricated member is composed of basic units taking a controller module as a core; each basic unit surrounds the controller module to form 1-4 pressure detection blocks, each pressure detection block is provided with at least one pressure sensor, and the pressure sensors are in signal connection with the controller module; each controller module comprises a router with at least two channels, and the controller module of each basic unit is connected with the serial channel of the router of the controller module of the adjacent basic unit through one serial channel of the router to realize point-to-point connection between the two controller modules; the geographic skin is especially suitable for monitoring falling rocks such as debris flow at highway and railway culvert openings, can perceive the condition of foreign objects like human skin, performs monitoring without blind areas and dead angles, and greatly reduces accidents and the workload of maintenance and troubleshooting.

Description

technical field [0001] The present application relates to a geographic skin for detecting debris flow disasters such as falling rocks on the surface of a railway track or a road surface, and other factors affecting driving safety. Background technique [0002] Highway culvert openings and railway track culvert openings are often affected by mudslides and other factors that seriously endanger driving safety such as falling rocks. At present, the most important technology is to use cameras and radars for monitoring, but this monitoring system is extremely vulnerable to severe weather. Especially in the climate environment such as heavy fog and heavy rain, the current monitoring system cannot work well. In addition, when objects such as plastic bags appear in the current monitoring system, sometimes it is difficult to distinguish, which brings great difficulties to the troubleshooting work. The workload is very large, especially the culverts and some slopes of the railway, whic...

Problems solved by technology

[0007] Over the years, many companies and research departments have tried to use video, infrared, laser, vibrating optical fiber and other technologies to realize the detection and alarm of foreign objects, but the effect in practical application is not optimistic.

Because the above-mentioned technologies will have interference and limitations in the implementation process, for example: the vibration optical fiber is more seriously interfered; laser detection is greatly restricted by terrain conditions; video technology will fail in foggy and rainy days, and video technology can only distinguish The size of the object, but the general type of the object cannot be distinguished, which will cause many false alarms

Therefore, so far, foreign object detection in fields such as railway pavement is still a difficult point
