Study on the design of intelligent gateway of the Internet of things
Abstract: Interact of things over the Interact based on the concept put forward is to extend and expand its client between any goods and goods to the exchange of information and communication of a network concept．The further development of networking technology,in fact，promotes seamless interactive technology．The so-called seamless interaction，that is，the full realization of the computer design of the digital world and physical world is tightly integrated way．
This article first introduces lightweight protocols and embedded operating system，Z-Stack
，the establishment of a standardized，open network server architecture，its architectural style is based on the most basic of network protocol has able to send short messages，radio-- Subscribe to the mechanism and the authentication mechanism and the protection of data security and other functions，is also a lightweight，scalable and good，open—ended．Then the test platform, successfully transplanted to W5500 within the protocol. Again, for wirelesssensor CC2530 and connectivity,and with the Internet connectivity was proposed design idea and made a test lab．Finally,in the above experiment is proposed based on test platform based on the external hardware circuit design ideas and hardware circuit design．
