| Abstract: | Distributed control system(DCS)is the trend of the current process control, so a simple DCS (SDCS) which consists of a host computer(IBM PC)and several secondary computers (8031 micro controller)is designed to apply to the automatic control of such slow processes with hysteresis as the control of industrial waste water disposal. In DCS, communications software is a basic element and the foundation of the realization of distributed control. So according to the asynchronous serial communication features of 8031 micro controller in multi controller system, a kind of master?? $slave asynchronous serial communication protocol is designed, and the design of the communications software of the SDCS in windows operation system is also introduced. |
