摘要
介绍了一种利用电流环进行通信的方法 ,并设计了与 RS- 2 32 C兼容的信号发送与接收接口电路 ,克服了利用现有微机上的 RS- 2 32 C串行通信接口通信距离短的缺点 ,实现了微机之间的长距离通信。
Introduces a way of communication by using current loop, and designs an interface circuit of signal sending and receiving, which could b e compatible with RS-232C It overcomes the disadvantages of now available computer serial communication interface which only has short-distance communication, and fulfils the long-distance communication between two computers
