The embodiment of the invention provides an abnormal wheel recognition system and method in a train braking state, and belongs to the technical field of rail transit. A plurality of infrared thermograms of each wheel rim of a train are collected and processed to form a complete wheel rim infrared thermogram of each wheel; the method also has the following steps: extracting the texture characteristics of a temperature difference band in the complete rim infrared thermogram of each wheel, and respectively calculating an error rate between each characteristic value of each parameter in the texture characteristics of each wheel and an average value of all the characteristic values of the parameter; and further judging an abnormal wheel. Compared with the prior art, the method has the advantages that only the wheels in a train passing process are detected, the recognition system does not need to be installed on the train, so the required cost is low; and due to the fact that the infrared thermogram of a wheel tread is detected, the accuracy of a judgment result is improved.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a system and method for identifying abnormal wheels in a train braking state. Background technique [0002] At present, the fault diagnosis of the train brake system uses the pressure measurement device of the vehicle brake system to collect the pressure change data of the train pipe, brake cylinder, and auxiliary air cylinder, and then analyze and process it to judge the vehicle-level fault. However, since the measuring device needs to be installed on every vehicle, the equipment cost is large, and since the truck has no power supply, it is difficult to install the device on the truck. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a system and method for identifying abnormal wheels under the braking state of a train, by extracting the texture features of the temperature difference band in the complete wheel rim in...
