Smart Home Wireless Network Construction

With the rapid development of the information world and the increasing of the people's living standard, requirement for modern intelligent security system is getting higher and higher. Intelligent security system is becoming a hot research area in the worldwide.Intelligent home security system is a synthesized services and integrated control system which is composed of intelligent monitoring system of door, intelligent alarm system and home automation control system. Among them, intelligent home control system and intelligent home security system are important part of intelligent home control system, which are responsible for controlling the switches of appliances and the security of people and their properties in daily life.This paper describes the detail design of the system. The system is composed of GSM mobile alarm module, control center of the host system, ZigBee wireless network, and signal detection of sensor. While introduce the framework of design, it elaborates the construct of various components in detail.ARM6410 is adopted as the mainboard of the system. It receives the alarm informations of the ZigBee child nodes from the ZigBee coordinator which is connected with it. And it sends these alarm informations to the receivers and the mailroom of security by SMS or MMS through the GSM module which is connected with the mainboard. Then, the system sends receivers'control order back to the host. And these ZigBee child nodes are controlled by the command from the ZigBee coordinator. The wireless monitoring network of the system utilizes the safe and reliable ZigBee technology. And this paper elaborates the application software of ZigBee nodes.This intelligent security system adopts the powerful ARM6410 as the central controller. The central controller provides a high integration design and favorable conditions for redevelopment. It is easy to send data and enhance the speed of transmitting with ZigBee child nodes which are used for monitoring the security. At the same time, it can reduce the cost. The system contains the GPRS transmit module. The module can deploy and disarm in distance.
