【Abstract】 In this paper, hardware connection and software design for the communication between BW-95 intelligent injection reagent feeder and general-purpose computer were intro-duced. The ring-network is used for connection of master and slave computers. Standard seri-al port RS-422 is used on the hardware to raise the communication distance. C++ languageis used for program design in the master compute, which makes gopd user interface.更多还原
