Family Security network 家庭安防网络 With the improvement of living standards, security requirements of the family have become more sophisticated, intelligent home security in recent years be taken more attention. Distributed and self-organizing network perh/rmance of WSN and the development of wireless communication offer the possibility for the realization of intelligent wireless home security. 随着人们生活水平的提高，人们对于家庭安防的要求也越来越高。近年来 智能化的家庭安防越来越引起人们的重视。无线传感器网络的分布式、自组织 的网络性能和无线通信技术，为实现智能无线家庭安防提供了可能。 Wireless Sensor Networks (WSN) is a new generation sensor network, which has very broad range of applications. The development and application of WSN would influence humans life and production to a far extent in many areas. U.S. Business Week and MIT Technology Review, in the prediction report of future development of technologies, both regard the Wireless Sensor Networks as one of the 21 most influential technologies and 10 changing world technologies in 21st century. Wireless Sensor Networks has brought a revolution in information perception for its characteristics of low-power, low cost, distributed and self-organization. 无线传感器网络是新一代的传感器网络，具有非常广泛的应用前景，其发展和应用，将会给人类的生活和生产的各个领域带来深远影响。美国商业周刊 和MIT技术评论在预测未来技术发展的报告中，都将无线传感器网络列为21 世纪最有影响的21项技术和改变世界的10大技术之一。无线传感器网络以其低功耗、低成本、分布式和自组织的特点带来了信息感知的一场变革。 The thesis has designed a home security network based on wireless sensors. The hardware design of network systems data collection uses Atmegal28L, which acquires the key information such as temperature, smoke, gas, etc. The system also uses infrared detection technology to detect illegal intrusion. The plate-making and hardware platform for data acquisition are all finished along with the thesis. And ZigBee wireless communications network will be set up to send detection message to the remote base station. Base station sends the receive data to the host computer through serial communication, host computer software processes data processing, real-ti
