Fault Diagnosis Of Train Center Plate Bolt Based On Digital Image Processing

In order to adapt the rapid development of railways, the use of high-tech meansto developed the TFDS system, instead of the traditional truck faults detection.TFDS system through a combination of software and hardware devices on the trainside and bottom to shoot, the picture of all parts, design a series of fault diagnosisalgorithm to access the TFDS detection platform, you can achieve the detection toavoid the shortcomings of the traditional artificial train inspection practices.The main work of the algorithm is based on TFDS system provides pictureanalysis center plate bolt failure site characteristics, the use of digital imageprocessing technology, combined with the idea of pattern recognition, design ahighly efficient, fast, high recognition rate of diagnosis algorithm to improve theTFDS system detection capabilities, rich TFDS detection type library.The algorithm design is divided into two parts: the location of the fault locationand fault interpretation. This algorithm takes advantage of digital image processing,pattern recognition, a variety of knowledge. As a design platform with C++Builder,the design of multiple modules of the system control software, the test platform.Seize the characteristics of the image through a detailed analysis of the samplepictures, clear design ideas, and a detailed breakdown of the positioning andinterpretation steps. Image flip, sharpen, split, gradient mapping a variety ofprocessing techniques for the design, the final completion of the work of positioningand fault interpretation. The overall algorithm to meet the requirements of real-timedetection, the test results are divided into direct forecasting and suspected forecast.All test results are credibility indicators, the use of credibility can the extent of thefailure to distinguish between. Papers late on the optimization of the overallalgorithm, read speed is greatly enhanced; fault interpretation of the order has beenadjusted so that each type of fault detection more reasonable speed improvedobviously. Algorithm package using dynamic link library to complete the fault coderead from the database, simplified the work of fault-coded to maintain and improve.The algorithm is universal, for all sounding stations in the Ministry of Railways, isnot limited to a single railway administration.Finally, describe the design process and the latter part of the test, verified thereliability of the algorithm. The memory of the algorithm has been tested, to ensurethe continuous operation of the algorithm.
