Research And Design Of The Controlling System For Smart Home Based On GSM Network And Power Line Carrier

With the rapid development of science and technology and the improvement of people's living standard, the demand of human to intelligent home life is gradually increasing. Intelligent home use of advanced network technology, wireless communication technology, computer technology, power line carrier technology, organically together with the home life related to the various appliances, through out the control network, which make the home life better, more efficient, more comfortable and securer. This subject is based on the actual demand of ordinary families, research and design of a complete intelligent home control system base on GSM network and power line carrier.Firstly, this subject analysis of the background, significance and development trend, according to the concept of intelligent home, focus on the power line communication of Narrow-band communication, Spread spectrum communication and OFDM technology, and research of DTMF decoding technology on the key beyond the GSM network voice communication, thus achieve the control of remote and real-time, and construct the overall program of intelligent home control system base on power line carrier communication technology.Secondly, detailed the technical principle of intelligent home control system from the point of view of system, given system model, analysis of the system working process, analysis of the system model from the view of engineering practice at the same time, and according to the model design of hardware circuit, and draw the circuit and design of PCB in the Altium Designer. Analysis of workflow of software from the hardware, analysis of software model from the actual programming at the same time, and programming system code by C language, compiled by keil, combined debugging of the software and hardware, implementation of coordination work on intelligent home control system.Lastly, testing on the intelligent home control system, the results show that the basic achievement of the function parameters in hardware and software for the whole system. In this paper, the integrated use of power line carrier communication technology, GSM network and micro controller technology, achieve the intelligent home control system base on GSM network and power line carrier, the GSM network to solve the remote and real-time control problem, while the power line carrier technology to solve the problem of home wiring, try to build an intelligent home control system of complete, low cost, easy operation, more suitable for general household. The system can be widely used in household appliances by remote and real-time control, because of simple design, low cost, strong practicality, flexible functions, convenient use, does not need to change the family wiring, and the system has broad applying prospect.
