Investigation of the Embedded Control System of Diesel Injector Nozzle Grinding

An embebbed system based on S3C6410 controller and Linux operating system is established to overcome the deficiencies of the traditional control system for high accuracy processing of grinding diesel injector nozzle because of its high speed and real-time performance. In this paper, the general structure of the system is designed firstly. Secondly, the detailed hardware platform is constructed and its peripheral equipment is selected. In addition, the software structure is presented. Finally, the main application program, including of processing control program and algorithm of the flow signal processing which is the key factor for high accuracy maching, is studied. The actual processing data shows that this system has good real-time performance, high processing accuracy and stablity.
