Automatic line obstacle monitoring and alarming method based on radar and video technologies

Abstract

The invention discloses an automatic line obstacle monitoring and alarming method based on radar and video technologies, and the method comprises the steps: counting line fault information, and making alarm judgment, and obtaining an alarm analysis and judgment result; and obtaining the alarm analysis and judgment result, and automatically alarming. A video behavior analysis technology is introduced, and behavior analysis such as intrusion monitoring and retention monitoring is carried out on a moving target in a monitoring area; the invention scans and monitors obstacles invading the railway locomotive clearance in real time, and alarms are given to related stations, trains and related operators in multiple modes of horn warning, wireless train dispatching voice alarm, alarm lamp alarm, short message alarm, monitoring terminal alarm and the like. Obstacles influencing driving safety can be accurately and reliably judged, and no missing report and extremely low false report are realized; the system is not in physical contact and connection with lines, roadbeds and the like in a monitored area, and it is ensured that normal driving and line construction and maintenance are not affected.

Description

technical field [0001] The invention belongs to the field of geological disaster monitoring, in particular to a method for automatic monitoring and alarming of line obstacles based on radar and video technology. Background technique [0002] At present, the device structure of the automatic monitoring and alarm system for the line obstacle of railway collapse and rockfall is sensor + protective net, which mainly adopts the protective net and the way of laying sensors on the protective net. The arrangement of sensors on the protective net can not only realize the alarm of rockfall, but also realize the early warning function. However, the monitoring method relying on the protective net does not have universal applicability. [0003] In recent years, the line obstacle automatic monitoring and alarm system for landslides and rockfalls, which automatically generates obstacle alarm information by analyzing the radar scanning data of a certain plane above the track, has been pilo...

AI Technical Summary

Problems solved by technology

This type of system only relies on radar scanning data to judge the alarm information, and it is difficult to identify the type and size of the object. In addition, ordinary radar scanning data is greatly affected by environmental factors such as precipitation and haze, and the false alarm rate of the system is generally high.
