Railway foreign matter clearance intrusion detection system and method

Abstract

The invention discloses a railway foreign matter clearance intrusion detection system and method. The railway foreign matter clearance intrusion detection system comprises at least one monitoring unit, an embedded foreign matter clearance intrusion detection unit connected with the monitoring units and a remote monitoring server. The embedded foreign matter clearance intrusion detection unit comprises an image acquisition chip for acquiring image data, shot by the monitoring units, of a railway area to be detected in real time, an FPGA used for judging whether a target exists in the image data or not through background subtraction frame by frame and extracting the features of the target to form feature vectors of the target if the target exists in the image data, a microprocessor for conducting foreign matter clearance intrusion judgment on the image data according to the feature vectors of the target, a remote monitoring server for confirming alarm information sent by embedded foreign matter clearance intrusion detection platforms and informing trains in relevant areas. By the adoption of the technical scheme, the railway foreign matter clearance intrusion detection system is high in recognition speed, high in detection efficiency and accurate in alarming and is suitable for an occasion needing long-distance along-railway foreign matter clearance intrusion detection.

Description

technical field [0001] The invention relates to the field of railway line safety maintenance. More specifically, it relates to a detection system and detection method for railway foreign object intrusion. Background technique [0002] Foreign matter intrusion refers to the behavior that solid objects with a certain mass and volume outside the railway facilities break into the railway line due to external force, posing a threat to the safety of railway lines and trains. It mostly occurs in the section where the highway crosses the railway, the section where the highway and the railway are parallel and adjacent, near the construction section, the main line of the railway, and the section where rockfall may occur in mountainous areas, so it has the characteristics of suddenness, irregularity and unpredictability. [0003] The detection of railway foreign object intrusion is mainly divided into two types: contact detection and non-contact detection. The contact detection syste...

Problems solved by technology

However, at present, most systems at home and abroad adopt the method of embedded acquisition combined with PC image processing. This method has poor real-time performance of foreign object detection, and it is impossible to realize dense layout along the line when detecting long lines.
