摘　　要：对T.30协议和T.4协议进行了深入的研究,设计出了可靠的传真收发流程。设计的传真数据解析树对数据进行解析。在μC/OS-Ⅱ操作系统下实现了无纸传真收发。该系统对资源要求低,能够在低端嵌入式硬件上运行,支持的最高传输速率为14 400 bps。用户可以将该系统视作一个传真机功能模块,嵌入到诸如可视电话之类的设备中。以较低的成本集成传真功能,也可以作为独立系统应用于移动办公场合。This paper conducts a thorough research on T. 30 and T. 4 protocols and designs a stable workflow of fax system. A special binary tree is designed to process the fax data. Under the μC/OS-Ⅱ operating system, the process of paperless fax system is achieved. It needs little hardware resources and can work on many low-end embedded devices. This system can communicate with normal and paperless fax with the speed of 14 400 bps. Users can take the system as a fax functional module to insert other equipments such as videophone. It can he integrated as a fax function module with low cost or applied to mobile office as a stand alone system.
