摘　　要：通信控制器需要完成与营连计算机的长距离通信,为了提高传输效果,减小误码率,我们采用了调制解调技术。应用调制解调器是利用模拟信道来传输数据所不可缺少的设备,位于模拟通道和数据终端之间,其工作过程为:在发送端,数字基带信号经调制变换为适合模拟信道传输的波形信号,经模拟信道传输至接收端,在接收端经过解调恢复成原始的数字信号,从而完成数据传输。On the base of the existed ground artillery gunnery commanding system, in order to realize the group and network of these systems, we need to extend the system again. The communication control unit(CCU) is a machine which can connect the group host computer with its subordinate command post computers and observe post computers, and which can scon the communicating channels, deal with the packet、 differentiate and ascertain the route etc.. This paper concretely exposits the design process, including bringing forward the project、designing the principle circuit、 constituting communication protocol and writing software.
