Optimized For Vehicle Wheelset Wear Detection Algorithm Based On DM6467

In recent years, the national economy in China has developed very fast. The transportationindustry is in rapid development. The vehicle wheelset wear detection technology is playing agreater role in rail transportation safety. Lots of literatures had been learned. At present, research ondomestic dynamic wheel wear detection method is still in its infancy stage. It agrees with the speedof vehicle at10-30km/h. In order to improve the speed of wheelset detection algorithm.Optimization methods for vehicle wheelset wear detection algorithm based on DSP had beenproposed. In this paper, the research has an important significance for the development of detectingtechnology on wheel abrasion tests.The optimization methods for vehicle wheelset wear detection algorithm based on DSP hadbeen proposed. The system using CCD to collect the train wheel to the outline of the image andtransfer the collected data to the DSP image processing unit. Processing the image data on DSP,then get the abrasion parameter. The main contents are:1、The wheel wear detection system based on DSP had been proposed. Which focused on thedesign of the data exchange module and multi-DSP parallel processing module.2、Completed the construction of the DSP development platform and application debugging.3、On the platform which had been build. Design the experiment for testing the rate of datatransfer in interface module. Implements the transmission function beturn DM6467and PC basedon TCP/IP protocol and socket network programming.4、Research is mainly focused on the abrasion detection method of wheel based on single DSP.Abrasion test image analysis unit is designed and the transplantation of vehicle wheelset weardetection algorithm is done. Packaging on the DSP, to generate an executable application. Based onthe achieved system. Focused on the design of optimization scheme based on DSP for vehiclewheelset wear detection algorithm. Offers several optimization methods, including softwarepipelining optimization, inline function optimization, memory optimization, etc.Finally, the paper carried out experiments on data interface module and image processingmodule. Build an image processing platform. Experimental results show that the image processingplatform had been build successfully. Processing algorithm successfully. Complete the experimentof data transmission between the PC and the DM6467. Analysis of experimental results, the averageof transmission time of per image from PC memory to DSP memory in one-way is meeting thedesign requirements of the system. Completed the experiment of the optimization of abrasion detection algorithm. The result of the experiment has carried on the qualitative and quantitativeanalysis. Deal to get a clear picture of the wheel on a continuous contour. Experimental results showthat the efficiency of optimized algorithm is3.3times as fast as before.
