The Brake Disc Crack Detection System Based On Image Processing Research

Along with the development of urbanization, the increase of population density, urbanrail traffic as an important tool of travel has become a new kind of low carbon transportation,receiving more and more attention. Many facts to prove that it can effectively solve the urbantraffic pressure and improve travel efficiency. Urban rail transit vehicle has the followingadvantages:The short distance between the two stations, time interval of vehicle braking isshort;High utilization of the vehicle;Vehicles require a higher security and reliability.Thevehicle’s braking system is the key components of the vehicle,It can guarantee the safety andreliability of the vehicle lane,The brake disc is the most important,Its performance and statuswill affect the braking effect of the vehicle. Therefore, the detection of cracks of the brakedisc is very important to ensure the security of the operation of Urban Rail Transit vehicles.In this paper, the following aspects:First of all, I do a lot of statistical analysis of the state of the brake disc, Related theory,the following conclusions:the crack is the main form of brake disc damage; and then I studythe rules and crack characteristics, select the characteristic parameters and physical.Secondly, This paper presents a new algorithm that is used to extract the crack,Thealgorithm uses the wavelet transform and image processing technology,based on the CurrentSituation of Digital image processing technology,Non-destructive testing technology,Vehiclefault diagnosis technology.The algorithm of the system proved an effective solution for therealization of the real-time monitoring of brake disc cracks.This topic design the rail transitvehicle brake disc crack detection system, Then the structure of the system are brieflyintroduced. Theory of the system is System collection brake disc image with CCD camera,The image was sent to the processing system, The brake disc crack appear by Industrialcomputer processing. With alarming,The characteristics of crack appeared brake disc appearthen warning At the same time,image with many of the crack are passed to the PC and forfurther processing.Finally, the algorithm of the rail vehicle brake disk crack detection systems,Experimental results show that the reliability of this detection method with high accuracy.
