Problems solved by technology

[0003] During the high-speed operation of the train, due to the braking or quick start of the train, the tread of the train wheel will be scratched, peeled off or out of round, and the rim will be worn, etc. These phenomena will cause safety hazards to the train operation
[0004] For example, the Chinese invention patent with the publication number CN1899904A discloses a method and device for on-line detection of train wheel size. The existing wheel size detection system usually adopts a centralized control method, and the detection devices distributed on the side of the track are controll

Embodiment Construction

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The relevant components in the invention are not drawn according to the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be changed arbitrarily, and the layout of the components may also be more complex.

[0032] See figure 1 , the distributed train wheelset size detection system of the present invention comprises connected:

[0033] Image detection box 1, used to obtain train wheelset images;

[0034] The central controller 2 is used to control the image detection box and detect the image of the train wheel set collected by the image detection box, and output the detection result of the size of the train wheel set;

[0035] The Ethercat communication unit 3 is used for communication between the image detection box 1 and the centr...

Abstract

The invention provides a distributed train wheel set size detection system. The system can greatly reduce the number of lines laid from an indoor control system to a rail edge image detection box, greatly improve the stability of the system, and bring more convenience for maintenance personnel to carry out system maintenance. The system comprises, sequentially connected, an image detection box used for acquiring a train wheel set image; a central controller used for controlling the image detection box, detecting the train wheel set image acquired by the image detection box and outputting a train wheel set size detection result; and an Ethercat communication unit used for communication between the image detection box and the central controller.

Description

technical field [0001] The invention relates to the technical field of wheel detection, in particular to a distributed train wheel set size detection system. Background technique [0002] With the rapid development of my country's railway industry, the speed of trains running on the main line is getting faster and faster, which puts forward strict requirements on the running status of train wheels to ensure that the trains run safely at high speed on the main line. [0003] During the high-speed operation of the train, due to the braking or quick start of the train, the tread surface of the train wheel will be scratched, peeled off or out of round, and the wheel rim will wear and other phenomena, which will cause safety hazards to the train operation. [0004] For example, the Chinese invention patent with the publication number CN1899904A discloses a method and device for on-line detection of train wheel size. The existing wheel size detection system usually adopts a centra...
