摘　　要：基于单片机技术,提出了一种通过改变工作电流和电压进行通信的半双工方式。主机设备通过改变供电电压将码流发送至外接控制器;外接控制器通过改变供电电流将码流发送至主机设备。验证试验表明:该技术能够实现双向数据通信,根据误码率自适应调整波特率,线路连接简单,为安装维护人员提供了极大便利。Based on the technology of single chip microcomputer,a half duplex mode of communication by changing working current and voltage is proposed.The host device sends the code stream to the external controller by changing the power supply voltage,and the external controller sends the code stream to the host device by changing the power supply current.The verification test shows that the technology can realize bidirectional data communication,adjust baud rate adaptively according to bit error rate,and the line connection is simple,which provides great convenience for installation and maintenance personnel.
