Embodiment Construction

[0029] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0030] (1) Accidental bow drop recognition and detection method of pantograph

[0031] Such as figure 1 As shown, this embodiment describes a method for identifying and detecting accidental bow drop of a pantograph. The method includes the following steps.

[0032] S1. Collect and buffer multiple frames of pantograph images, and perform recognition processing on each frame of pantograph images to identify the pantograph.

[0033] S2. The multi-frame pantograph image is divided into a judgment image and a verification image, the judgment image is used to judge whether the pantograph has a bow-down trend, and the verification image is used to compare results obtained based on the judgment image. Perform verification.

[0034] S3: Calculate the height of the pantog...

Abstract

The invention discloses an accidental-pantograph-falling identifying and detecting method and system. The method includes the steps that pantograph images are collected through a camera installed on a rail transit train, pantographs are identified with the image processing technology, and the heights of the pantographs in all frames of the pantograph images are computed; according to the parameters of the heights of the pantographs, whether the pantographs have the falling tendency or not is judged, whether the pantographs have pantograph falling defects or not is verified, and then whether the pantograph falling defects are accidental pantograph falling defects or not is judged according to the current traveling speed of the train. As the identifying and detecting method and system are based on image processing, whether accidental pantograph falling occurs or not can be detected in real time, emergency processing can be conveniently conducted, accidents caused by accidental pantograph falling are prevented, wrong identification of transient pantograph falling actions generated by tunnel passing and the like can be further avoided, and the confidence level of pantograph falling alarming is effectively increased.

Description

Technical field [0001] The invention relates to the field of catenary, in particular to a method and system for identifying and detecting accidental bow drop of a pantograph. Background technique [0002] The catenary is a high-voltage transmission line that is erected in a zigzag pattern over the rails in an electrified railway for the pantograph. The catenary is the main frame of the railway electrification project. It is a special form of transmission line that is erected along the railway line to supply power to the rail vehicles. Generally consists of contact suspension, support device, positioning device, pillar and foundation. [0003] The development of electrified railway is an inevitable trend of railway modernization. Electrified railways all use electric traction. Electric locomotives must reliably obtain electrical energy from the contact network under high-speed operating conditions, otherwise it will affect the train operation and the performance of the electrical ...
