3 通信模块 
3.1 RS-422通信标准 
      RS-422标准的数据信号采用差分传输方式，也称作平衡传输，其全称是“平衡电压数字接口电路的电气特性"。 
      其接收器采用高输入阻抗，发送驱动器有比RS232更强的驱动能力，故允许在相同传输线上连接多个接收节点，zui多可接10个节点。即一个主设备(Master)，其余为从设备(Salve)，从发备之间不能通信，所以RS-422支持点对多的双向通信。 
      RS-422的zui大传输距离为4000英尺(约1219m)，zui大传输速率为10Mbit／s。 
3.2 数据交换功能实现 
      本系统通信模块采用RS-422标准，线路长度约为200m，故通信的可靠性可得到保证。差分线路驱动器使用AM26LS31芯片，差分接受器使用AM26LS32芯片，微处理器的串行输出口和输入口分别与驱动器输入和接收器输出相连，并使用差分开路自动故障保险终端连接配置。 
      从而在发送器输出端为高阻状态时保证接受器输入有至少200mV的电压信号，使输出不会出现未知的状态，提高可靠性，完成与上位机间的数据交换工作。另外，考虑到多机器人手臂的应用情况，在手臂控制器中设有拨码开关来设定编号，与上位机的数据交换必须包含该编号，并由此来判断通信时目标控制器的具体位置。
