摘　　要：针对Unicable器件的广泛采用,提出一种在数字卫星接收机中实现Unicable功能的方法。首先介绍了Unicable技术的原理、控制信号时序、数据格式与指令定义,然后对接收机中Unicable软件控制模块的整体框架、初始化和调谐流程、通信冲突检测与异常处理、实现与测试等进行了阐述,实验表明该软件控制模块在不同数字卫星接收机平台中得到了良好的应用。In view of the widely used of Unicable devices, a method of achieving Unicable function in digital satellite receiver is presented in this paper. Firstly, the principle, control signal timing, data format and command definition of Unicable technology are briefly introduced. Secondly, the overall framework of Unicable software control module, including initialization, tuning process, detection and handling of communication collsion, implementation and test are mainly illustrated. Finally, it proves that the module is well used in different digital satellite receiver platform.
