Title  Design of Remote Control System Based on Internet of Things

Abstract：As a technology that extends the exchange of information between objects and articles, the Internet of Things has become an important part of the new generation of information technology. Based on the fact, the smart home was born. In this system, the choice of wireless short-range transmission protocol is the primary problem, ZigBee technology is a good solution to the problem: it has a short, low consumption, reliable and other advantages, well adapted to the intelligence Home system environment.

The smart home system in this paper mainly used the ZigBee technology and GSM communications technology. First , the article describes the principle of ZigBee technology, including its level and communication between levels, and then describes the CC2530 chip; after that, this paper gives a brief introduction to GSM technology and the SIM800A chip. Next, this paper is pided into hardware and software parts, concentrates on the description of the design plan and the experiment process. The hardware part includes: the core of ZigBee module part, the basic characteristic of CC2530, CC2530 core circuit diagram, specific peripheral circuit diagram; GSM module core, SIM800A basic characteristics, related circuit design. The software part includes the communication protocol between the ZigBee master node and the ZigBee terminal node, the communication program between the GSM module and the ZigBee module, and the GSM related AT command setting.

Finally, the system is tested in this paper, which verifies that the design can basically accomplish the expected intelligent home system function.
