Research Of Home Security System Based On ZigBee

With the development of modern science and the raising of people's living standard, people pay more and more attention to their living environment. They want an intelligent living space which makes their life safer, more comfortable and more convenient. The home security system takes the advantage of computer technology and network technology to combine all the sub-system related with our home life together and manages them as a whole, so as to provide a safer, more comfortable and more convenient living environment. This thsis introduces the development of home security system at home and abroad.Through the analysis and comparation of several related short-ranged wireless network technology standards which are popular nowadays, I think ZigBee, a new low-power, low-rate and low-cost short-ranged wireless network technology, is better suitable for the wireless home security system. So I choose the ZigBee as networking method to set up the home security wireless communication network with mesh topology. This network is self-organizing, self-repairing, and sense node can join dynamically, alarm automatically.This thsis researches and analyses the ZigBee protocol standard in details, including the structure and function of each protocol layer. Then introduces some concepts related to the ZigBee application development. I adopt TI's single-chip solution CC2430 to build our home security system based on ZigBee. My work contains overall plan of the system, the hardware design of the system and the software design of the system.This thsis programs a GUI(Graphical User Interface) based on PC serial with VC6.0 MSComm. It enables our users to inquire the temperature, smoke, infrared. It can relieve the alarming state of the sense node through sending the relieving alarm command to the sense node. And it can show the address of the device , the address of the device'father, and the network structural relationship.
