Design of Embedded Network Communication Module

Taking the network communication of smart home as an example, and based on the current market conditions and technical standards, this paper makes a comprehensive research on the embedded network communication module.Compared with products with simple functions and low interaction level, we propose and implement a network communication scheme with high reliability, high cost performance and convenient operation.The embedded network communication module based on TCP/IP protocol external hardware protocol stack and all over the world telephone network communications, using 485 bus structure form, so it can realize the remote communication and to facilitate foreign expansion of the characteristics, finally, to achieve the purpose of intelligent control connected objects.
