Problems solved by technology

[0002] The railway power line spans long, and the catenary has been working under various complex climatic conditions for a long time, especially in harsh environments such as strong winds, and often shifts, lifts and reverses. At present, there is no domestic method to detect the offset of key parts of the catenary. device, which makes it impossible to record the dynamic offset of key parts of the catenary in real time, which is not conducive to the safe operation of railway electric locomotives

Embodiment Construction

[0046] The dynamic offset detection device for key parts of catenary is composed of three parts: online key part detection mark, online CCD detection device and central computer room data center.

[0047] The key parts on the line refer to the parts that need to be measured, such as the catenary mid-span contact line, the catenary cable, the contact line at the suspension positioning point, and the suspension string, such as figure 1 shown.

[0048] The detection mark is installed on the detected object of the key parts of the catenary, such as contact wires, catenary cables, hanging strings, columns, etc. in the section of the detected catenary, and does not affect the operation of the pantograph when it is powered. The detection mark has a certain brightness, which is determined by Composed of light-emitting LEDs or light-retroreflective materials illuminated by light sources. like figure 2 , 3 , 4 shown.

[0049] The power required by the LED is supplied by the battery i...

Abstract

The invention relates to a contact network key position dynamic offset detection method and a device thereof. A detection identification is arranged on objects at the key position of the contact network to be detected such as contact line of the section, carrier cable, dropper and upright of the detected contact network, an online CCD detection device is arranged on the upright of the contact network, a CCD camera acquires video image of the contact network, the detected displacement and quantity of motion are stored and amplitude, angle of twist and corresponding time course curve are drawn, and the online CCD detection device transmits the data to an upper machine room data center by virtue of a wireless communication module. The method and device of the invention are non contact and self-calibration, practicability is strong, and synchronous monitoring is carried out, so as to obtain data and image; amplitude, frequency, angle of twist and corresponding time course curve are recorded in real time and are used for analyzing influence of the stability of the contact network in high wind environment or under the action of other factors, and travelling is guided according to the real-time deviation state of the contact network.

Description

Technical field: [0001] The invention relates to a detection method and a device, in particular to a method and a device for detecting the dynamic offset of a key part of a catenary of a railway power line. Background technique: [0002] The railway power line spans long, and the catenary has been working under various complex climatic conditions for a long time, especially in harsh environments such as strong winds, and often shifts, lifts and reverses. At present, there is no domestic method to detect the offset of key parts of the catenary. device, which cannot record the dynamic offset of key parts of the catenary in real time, which is not conducive to the safe operation of railway electric locomotives. Invention content: [0003] The technical problem to be solved by the present invention is to solve the above-mentioned existing problems in the prior art, and provide a method and device for detecting the dynamic offset of key parts of the catenary, and record its amp...
