This paper discusses an embedded access platform, which takes S3C2410 as
the center core and is built upon the Linux operating system. Based on the
character and advantage of ZigBee and GPRS, this article advances the
solution scheme of the wireless sensor network gateway.
Mainly analyzes the software design of the gateway, including the way to
realize the connection of ZigBee protocol and GPRS network, along with the
design of data conversion task between ZigBee network and GPRS network.
And it proposed a solution of data loss, which is caused by the different
transmitting rates of ZigBee module and GPRS module.
This paper also describes the structure of hardware platform and running
process, and analyzes the structure of the three layers software system, as
well as PPP protocolpsilas characteristics and transplanting key point.
As a result, the wireless data communication link between the embedded
gateway and GPRS network is set up, and the solution of keeping the gateway
on line is proposed.
