Based On The Arm Home Security Systems And Communication Modules

Nowadays, AMI (Ambient Intelligence) is becoming a studying hotspot in the worldwide. As the basic system of the AMI program, the Smart Home System is the prerequisite for AMI's realization. The Smart Home Security System, which is the important part of the Smart Home System, is elaborated in this paper.It is an unstoppable trend to make use of ARM Linux Embedded System and Wireless Network Technology in Smart Security System. ARM Linux Embedded System is powerful and used widely. Wireless Network Technology is in keeping with the trait of communication of home network. While makes the system more flexible, and eliminates the need for wiring.This paper is based on AMI technology as a standard. After the analysis of the Smart Home Security Systems in internal and abroad, paper proposes the plan that the system contains three parts:system control center, ZigBee wireless sensor network and mobile nodule, which is combined with living environment in our country. As the central controller, S3C6410 handles all alarm signals which are sended by ZigBee wireless network and sends them to the user who use mobile module. User can send controlling messages, which is handled by central controller, to control the appliances. User can also learn the situation of home from the MMS sended by the system.While finishing the application program's design of GUI of the embedded system, paper discusses the system problems of compatibility and scalability. And paper introduces the knowledge of SMS and AT command. It also contains how to package the SMS PDU and achieve the function of sending and accepting in the embedded system. At the end of this paper, it introduces the knowledge of MMS and analyses the WAP(Wireless Application Protocol) protocol, packages the MMS PDU and anaslyses the two methods of sending MMS.
