Implement of Embedded Gateway based on ARM
A technique of converting different serial communication protocol to Ethernet protocol is presented in this paper, which is implemented by embedded gateway. We design this gateway in structured method, and its key portion protocol converting module is based on 32 bits processor of ARM7TDMI kernel. Besides, there is an inline μCLinux operating system inside the processor. At the end, converting different serial communication protocol to Ethernet protocol comes true in the building automation, and thus it is convenient to monitor and control together.
