| Embedded System Design plays an important role in modem electric design. As an important component of miniaturization and/or intelligentice instrument carried out, and owned independence intelligence property, it takes more and more extensive application in each domain ,i.e national defence , space navigation , commuicaion , traffic, industry ,energy and also.With modern science and technology development and the improvement of living standards, residents of the residential function make more higher quality requirements. With its safe, smooth information and services, intelligent residential greatly improve the household's favorite. So intelligent become modern residential developments. Therefore, it is a very important significance to research and develop intelligent products which is suitable for people's asking.The communication of traditional intelligent home control system components is based on wireless network . It has the advantage of reliability and high transmission efficiency. But the wiring problems also constraining its development. Therefore, the wireless network is more of the focus of public attention because of the characteristics of space constraints. With the development of domestic intelligent and the emergence of family information services, to ordinary families, HAN (Home Area Network) will also become absolutely necessarily. Bluetooth is very suitable for use in HAN, which is remarkably in recent years as a short-range wireless technology.In this paper, both at home and abroad, there has been appeared the intelligent home control system. With the domestic residential real intelligent, a set of multi-function smart home control system design has been put forward, and realized the intelligent home control design. According to the home environment to analyse the structure of intelligent home, and make use of embedded platforms, network technology, computer technology and sensor technology and others to construct home building intelligent software and hardware platform. It is achieved the equipment working conditions which are at close range through the system keyboard to control household appliances.⑴This paper shows the composition of the system and hardware architecture. The core component is the PHILIPS company's production LPC2292 ARM chip. In this part, there is a detailed explanation of each module interface design, and a description of the entire hardware structures in detail. In this part, it is also emphatically described the principle of Highlighting the HCI module and memory expansion outside, and detailedly expatiated the working principle of Water heaters and air-conditioning as well as the control process.⑵Then analyzed the personal PAN technology, this paper makes in-depth research about core protocol and features of Bluetooth, which is with the combination of smart home.⑶According to the concept of the function application of all parts of the system put forward the program design process of the whole system related part.This program design process is including data collection, the Chinese menu display, serial communication, water heaters prevent dry, sub-timing and air-conditioning work mode, and so on. This paper also introduces the system environment.⑷Finally, I sum up the entire process, analyze disadvantage and shortage, and prospect the future work..The system features :⑴a high degree of system integration;⑵the use of powerful new devices, such as DS18B20,which saves resources of ARM and reduces the volume;⑶have the ports of extending system function, which is easy for system expansion or upgrading;⑷the manufacture, the installation and the convenience of maintenance of the system;⑸it is simple to manipulate, and users can easy to learn and use. Thus, the system is low cost and high performance. |
