Abstract


Yoke flat pin as the train coupler and buffer device connected accessories, if it is lost or broken the train separation will result in a great deal of hidden dangers to train traffic safety; brake beam struts round pin loss is caused by train brake beam parts off the main reason of the accident. Therefore, the train hook tail flat pin and brake beam struts round pin failure check is to ensure the necessary conditions for train traffic safety. The traditional way of checking for artificial static detection of the two major fault With the continuous improvement of train speed, train maintenance cycle is greatly shortened, artificial static detection method has low efficiency and poor reliability shortcomings, it is difficult to meet the requirements of the railway sector. Therefore, the computer automatically detect the two major categories of failure has extremely important significance to the protection of train operation safety. The issue is the continuity of train operation dynamic fault detection system (TFDS). The main research directions based on digital image processing, by analyzing the the train hook tail flat pin and brake beam struts round pin two categories of images fault features, design and complete failure of the two categories of images automatic recognition algorithm. First detailed description of the field of classical algorithm for this topic need to use the digital image processing, such as image geometric transformation, based on the histogram of the gray-scale transformation, smoothing, gray mapping using gradient edge detection information, digital image processing, template matching algorithm, and explains the reasons for this topic using these algorithms. How to design according to the the hook tail flat pin and brake beam pillar round pin two categories image features can be accurately extracted part of the algorithm of the two broad categories of image features, and how to design efficient and accurate fault judgment algorithm, these two parts of this topic focus and difficult part. The subject eventual adoption of the digital image processing classic algorithm and window grayscale mapping algorithm to complete the design work of the two sets of fault identification algorithm. The algorithm function implementation requires software platform to support the topics chosen C Builder visual programming software and programming software, complete test platform for the design, commissioning and DLL files generated work. Finally, fault identification algorithm existing image samples of the \The practical application shows stable operation algorithm, algorithm design requirements to meet the recognition rate.
