This work of this monograph adapts to the development tendency，applying the single chip microcomputer to cooling water temperature automation control system of ship main engine. First of all, the monograph analyzes the function demand of all modules of the control system，specifies the technique request，it provides a solid foundation for the subsequent system design ; then，confirms the choice of the hardware parts and the software arithmetic according to the system function: finally，this monograph provides a whole plan about hardware and software design for the al1 main engine cooling water temperature control system that based on single chip microcomputer. At the same time，discusses
