Notes:
The detecting instrument for surface quality of steel ball bases on embedded controlsystem and image detection technique, and is applied to detect surface defect region of steel ball inbearing. Its control system requires excellent real-time character and control accuracy. This paperputs forward a new design for controller of detecting instrument. We adopted TMS320LF2407Awhich produced by company TI as main processor, and integrated CPLD to develop an embeddedcontroller. We used the Ziegler–Nichols tuning methods to get PID control and designed hardwarecircuit. We realized the function of correlative logic elements through programming, andconstructed an embedded multitask operating system based on the transplant of μC/OS-II onTMS320LF2407A. It solved problems about intricate structure and bad real-time character existedin traditional control module. The result of simulation and experiment indicates that this controlsystem satisfied excellently the requirement of high speed and real-time image detection
