Embodiment Construction
[0027] A detailed description will be given below of embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with some specific embodiments, it should be noted that the present invention is not limited to these embodiments. On the contrary, any modification or equivalent replacement made to the present invention shall be included in the scope of the claims of the present invention.
[0028] In the example, as figure 1 As shown, it is a flow chart of a fault detection method for a catenary suspension device on a line with a large slope. In this method, firstly, a high-definition camera and a high-speed camera installed in the locomotive cab are used to shoot the line catenary suspension device, and the image is preprocessed such as gray scale transformation and image enhancement. The features of the preprocessed image are extracted, and the processing results are compared with the sample images through a series of ...

The invention discloses a fault detection method for an overhead line system suspension device on a large-gradient line. According to the method, a high-definition camera is used for shooting suspension device images along a line, and gray scale transformation, image enhancement and other preprocessing are carried out on the images. Features of the preprocessed image are extracted, and a processing result is compared with the sample image through a series of processing of the feature quantity to realize fault detection of the suspension device. Compared with an existing detection method, the fault detection method provided by the invention can effectively improve the fault detection time consumption and the detection precision, has certain superiority, and better meets the requirements onthe suspension device fault detection method at present.
Description
technical field [0001] The invention relates to the catenary field, in particular to a fault detection method for a catenary suspension device. Background technique [0002] With the increase of high-speed railway operation speed, in order to ensure the safety and reliability of pantograph and current receiving system, it is necessary to have a high-quality catenary system, which puts forward higher requirements for catenary detection. The catenary is the main frame of the railway electrification project composed of contact suspension, support device, positioning device, pillar and foundation. It is a special form of transmission line erected along the railway line to supply power to electric locomotives. The suspension device of catenary mainly refers to the contact suspension device including contact wire, hanging string, catenary cable and connecting parts. The catenary 4C detection device (catenary suspension state detection and monitoring device) is a device installed ...
