| The Smart Home industry has obtained initial achievement in China as a newly emerging industry. Home security system is an important part of intelligent residential system.The purpose of researching this system is to realize home security automation and provide an intelligent, safe and convenient living environment. At present,wireless security products in markets have a lot of shortcomings,so on the base of aggregate analysis of the current situation of home security system, we develop an embeded wireless secrurity system which has better perfomance as a component of the smart home system.This paper introduced embedded technonogy,RFID and GPRS used in the home security systems. The paper is discussed according to the following sections:At first, the current situation and the trend ,and also the necessity of smart home security systems has been analysised. Secondly, through the analysis and comparison of the technology we used in the sysytem, the HomeRF is the best technical norm which is suitable for wireless home security system. Furthermore, the paper expatiates the specification.The hardware system was designed on the base of the functional analysis of smart home security system. This system is a modularized system, which is consisted of several function modules.The hardware system includes main controller and sensor, telephone modules, voice modules, wireless transmit/receive modules, GPRS and image acquisition module, power supply modules, etc. The designing idea and circuit principle of each module has been introduced .And the references of the important electron components are included in this paper.The embedded operation systemμCLinux's transplantation and implementation in the home security system is discussed in details in the paper.Then Multimedia Messaging Service has been analysised and studied in the paper, and the implements based on WAP are introduced too.The tests proved that this solution is reliable, entire and reaching the designing requirements. |
