Railway crossing locomotive detection system based on laser scanning

Abstract

A railway crossing locomotive detection system based on laser scanning disclosed by the invention comprises a system and a laser radar. The system is composed of the laser radar and a locomotive detection algorithm, the laser radar is installed in a railway crossing area, then the area detection range is divided, and the railway crossing is scanned in real time to form dynamic data. A crossing background self-learning algorithm and a locomotive area detection algorithm are adopted to detect crossing locomotive objects, then targets in a scene are extracted from real-time scanning data, the current scanned locomotive objects are identified and classified, and a time state data sequence of the locomotive entering and leaving the crossing is established according to the scanning data; and finally, the running speed of the locomotive is calculated. According to the invention, the problems of few locomotive detection methods, poor detection stability and incomplete functions under the current complex background of the railway crossing are effectively solved, support is provided for full-automatic safe operation of the unmanned railway crossing, and the intelligent level of safety supervision of the railway crossing is further improved.

Description

technical field [0001] The invention relates to the technical field of port railway traffic intelligent supervision, in particular to a laser scanning-based railway crossing locomotive detection system. Background technique [0002] Most of the detection systems of short-distance vehicle intrusion alarm detection technology at modern railway crossings in my country have simple control logic and require a lot of manpower and material resources to participate in manual control throughout the entire process. For the research on railway crossing detection, the earliest method used is the track circuit , due to the many shortcomings of the track circuit, such as single function, easy to report errors, and a large amount of installation tasks, the embedded monitoring system based on infrared sensing technology was subsequently developed, but the detection accuracy of this technology is limited, and because the sensor The difference in height will affect the final result, so it is no...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a railway crossing locomotive detection system based on laser scanning, to solve the problem that the controllers of some existing alarm detection systems proposed in the above background technology are relatively complicated and have low reliability. The distance will be affected by some other factors (such as frequency band loss, etc.), and its detection is only limited to measuring the relative distance and relative speed of the target object, so the detected object cannot be accurately identified, and some existing detection systems are It is a passive acceptance of data, and its perception effect is greatly affected by environmental factors, and it cannot solve some key problems
