Design Of Intelligent Home Control System Based On ZigBee Technology

Smart home system is to connect the facilities and devices, to form a home network, which provides people more comfortable and convenient life. The traditional smart home systems are controlled and communicated through kinds of wires and in that case people are involved with these troublesome wires or cables and it is hard to expand the system to compliant some new appliances or devices. Wireless network not only can provide much more flexibility and mobility and save cost and energy spent in synthesizing wiring, but also can correspond to communication characteristics of home network. Therefore, this paper makes a design of intelligent home control system based on ZigBee technology. In detail it:(1) Deeply studies several kinds of intelligent home control technology widely used at present, and points out the advantages of adopting ZigBee technology in intelligent home control system.(2) On basis of functions and demands of intelligent home control system,studied the system interior network topology, the network configuration, the network connection, the vertex has tied up decides and the data transmission mechanism, and produced the ZigBee agreement each level design proposal.(3)According to the overall architecture of home intelligent control system, designed a wireless home control system based on ZigBee technology, the hardware scheme included ZigBee family node and PCB,microstrip patch antennas, the software included the main program, serial communication procedures, LCD driver programes etc.(4) Through constructs the test and simulation platform, test the wireless correspondence and the string correspondence of the Smart home system based on ZigBee technology, pasted the piece antenna to the micro belt the standing-wave ratio and the directivity simulate the standing-wave ratio and the directivity of the micro belt antenna , and analysis the test and simulation result.(5) Elaborated the representative application at family life, the four meter copy system, produced the overall structure, the network assembled plan and the realization flow of this system, elaborated the buildup principle of wireless water meter module and wireless ammeter module in the four meter copy system of the family life.According this article designed intelligent home control system based on ZigBee, family life can achieve automation, cyberization, and intelligentization. Through the analysis of the representative application of the four meter copy system as well as the test and the simulation, indicated the system design reasonable is feasible, basically achieved the anticipated design goal.
