    Abstract: According to the requirements and characteristics of burning regeneration diesel particulate filter system, design and implement a control system based on MC9S12P128MQK single chip microcomputer. The system uses a structured design method, including three parts: Control unit, Display unit, and Calibration unit. The control unit collects information from sensors and drive actors, through the regeneration of the trigger strategy and temperature closed loop strategy to achieve combustion regeneration; the display unit can display the system real-time working condition, have sound and light alarm function and provide manual operation by the key, which is connected to the control unit by CAN bus communication; the calibration unit through CAN bus communication can realize PC to controller parameters real-time display, read, modify, storage, and program update. The controller has been applied to the control of diesel exhaust in some cities.
