A kind of control system which consists of high performance ARM microprocessor and embedded real-time operate system is put forward and researcheed. The control object and the requirements of system are analyzed; the general design project is determined; the control arithmetic and software structure are introduced in the end. ARM microprocessor is the intelligent core of the system. Matched with μCOS-II RTOS and application program, the system can complete the functions of information collection and real-time control.
