BW-95型智能注射式加药机与PC机间的通讯

COMMUNICATION BETWEEN BW-95 INTELLIGENT INJECTION REAGENT FEEDER AND COMPUTER

介绍了BW—95型智能注射式加药机与通用计算机间通讯的硬件联接及软件设计．主从机采用环形网联接方式．硬件上使用RS－422串行口，提高了通讯距离．软件设计中主机采用C++，使其具有良好的用户界面．

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.
