5.8mm枪弹自动称重系统中通信系统的设计
Design for Communication System of Automatic Weighing System for 5.8mm Bullets
【摘要】 在5.8mm枪弹自动称重系统中,通过RS-485接口将4台PLC组成网络,上位机可以集中监控.利用RS-232C接口使PLC与电子天平通讯,并设计了RS-232分时转换器,实现了一台PLC与4台电子天平通讯.
【Abstract】 In this paper, the method for building a simple automatic weighting system of 5.8mm bullets with PLC and RS-485 interface is introduced. In addition, a RS-232 time-sharing switcher is designed allowing a PLC device to communicate with four electronic balances conveniently.
