Abstract: With the spread and applications of wireless sensor network in the coal mine, the request is pointed out to connect wireless sensor network with Ethernet which is the trunk network under the mine. The gateway is one of the most important parts. By analyzing communication reality methods of wireless sensor network to Ethernet, the blue print of gateway based on high performance network controller and embedded real-time operating system is pointed out. The key techniques and methods on how to realize the gateway with embedded microprocessor S3C4510B and embedded real-time operating system VxWorks are expounded.

Key words: wireless sensor network, gateway, Ethernet, embedded operating system
