基于因特网的远程家居自动控制系统研制

提出了一种基于因特网的远程家居自动控制系统解决方案,给出了系统各组成部分的硬件、软件详细设计与具体实现.系统由基于C8051F005单片机的嵌入式控制器和家居Web服务器组成,嵌入式控制器有8路A/D转换通道和32个I/O端口,用于连接传感器和控制家电设备,嵌入式控制器通过RS232串口同家居Web服务器进行通讯,Web服务器设有基于JSP技术构建的自动控制网站,用户可通过嵌入式控制器或WWW浏览器控制家电设备.系统采用动态DNS技术将动态IP地址映射为一个固定域名,通过此域名可方便地访问家居自动控制网站实现对家居的远程监控.系统扩展灵活、功能强,价格低廉.

Development of an Internet home automation system

This paper presents the design and implementation of an Internet home automation system that can monitor and control home appliances via the World Wide Web. The system consists of an embedded controller and a PC-based home Web server. The embedded controller is connected to the home Web server via RS232 serial port. The home appliances are connected to the input/output ports and the sensors are connected to the analog/digital converter channels of the embedded controller. The home automation Website residing on the home Web server is based on the combination of Java Server Pages and JavaBeans. Dynamic DNS service technology is taken to fix the dynamic IP address to a static domain name to allow the server to be more easily accessible and the password protection is used to block the unauthorized user from accessing to the server. The home appliances can be monitored and controlled locally via the embedded controller, or remotely by a web browser. The system is scalable and allows additional appliances and sensors to be added to it with little changes to its core.
