Abstract: Embedded underground application software design of mine rescue communication system was proposed since the communication between underground rescue site and command center was delay, and the rescue efficiency was low. System function of hardware software structure was realizated based on S3C6410 platform and embedded WinCE 6.0 as operation system in VS2005 development environment, including video display, three party service(volume adjustment), environment parameters display, danger alarming and data storage block. Modularization was realized by adopt multithread, including receive-thread(receive audio and video data and environment parameters information data),thread display, alert thread judgment. Environmental and video and audio information of underground rescue progress conveyed to first-aid staff and underground base station and rescue command center instantaneously and accurately，was helpful to command center on master underground site rescue situation instantaneously and command implement more effectively.
