The Research On The System Of Testing The Angle Of The Sealed Inclined Plane Of Oil Nozzle Base On Multipage Image Comparison

The oil nozzle is an important part of the supply department of diesel. The homemade diesel need to be tested when it have worked per 20000 kilometer(almost 500 hours).The proportion of needing to be repaired or replaced among all tested oil nozzle is 30% to 50%. The incorrect angle of the sealed inclined plane of oil nozzle is an important factor to the forepart invalidation of the oil nozzle. The logical angle can make the fuel, which is sprayed in cylinder by oil nozzle, atomize averagely, have good penetrability and burn adequately , then make the diesel power work fully, reduce oil waste and pollution. But so far, there is no direct method to test the angle of the sealed inclined plane of oil nozzle.To meet the need of test the angle of the sealed inclined plane of oil nozzle ,the paper develops an advanced system of testing the angle of the sealed inclined plane of oil nozzle, using beam imaging technology, fractionizing pixel and test technology of comparing several images. The system uses the industrial computer as the core part, using optical fiber endoscope, high resolving power CCD sensor, industrial computer, the raster displacement sensor, the servo electromotor and working table to compose a testing and controlling software and hardware working table ,which is controlled by computer, to carry out testing the angle of the sealed inclined plane of oil nozzle .The method researched in the paper can carry out images' sampling automatically and comparing the multiple layer images' alignment quickly. The intelligent measure and control image system , which can figure out the right measuring result, will make the process of testing the angle of the sealed inclined plane of oil nozzle automatic and intelligent. Using the advanced method of automatic detection and monitoring instead of traditional method, will lower the working intension, raising the efficiency, lower the influence of the artificial factor, thus raise the accurate rate and credibility.The paper will narrate the system's design, basic theory and concretely realization all-around from several sides, such as optical fiber endoscope, CCD sensor, capturing image, measure and control circuit using SCM and system's overall design. To make this method used better in the system, the paper makes some exploration on the method and implement to get the rationality of the tested result about the angle of the sealed inclined plane of oil nozzle.
