Abstract: In order to solve the heavy equipment and hard to build fast networking problems in mine emer- gency rescue communication network, a portable network terminal equipment is designed in this paper. It uses WinCE system and TCP/IP network protocols, including WinCE transplantation, network transmission and WinCE embedded application development. A mutually for the client server network communication is realized, and the real-time transmission of underground video, audio, environmental parameters acquisition information is achieved. Finally the embedded terminal and the PC host combined joint debugging are conducted. Test data indicate that audio network transmission is efficient, and the software code is with good encapsulation and portability.
