摘　　要：提出一种完整的嵌入式Linux系统平台下的前端控制器的软件,介绍该前端控制器的GUI界面的设计,MAC层数据的接收,多线程技术的应用以及如何采用多线程技术避免对串口资源的独占。该系统能够实时地进行信道的管理,与通信机和管理计算机相连后即可实现整个HFC网管系统的运行。The paper introduces a software design of Headend Element of HFC Network Management System based on embedded Linux system platform, the GUI design of the Headend Element, the data receiving in MAC, the application of the multithreading technology and how to use the multithreading technology to avoid the monopoly of the Serial Port. The system can realize the real time managing of the channel. Once it connects with the management computer and the communication equipment, HFC Network Management System will work.
