We can also quickly and accurately access environmental information, it’s a good solution to monitor and control the remote equipment. Embedded systems and Inter are bined to be the mainstream of the present study, it has a broad development prospects. This thesis is based on current research focus. Through the prestudy and work such as learning the principle of the arm as an Inter server and being familiar with the way of munication between arm underlying driver and webpage , laying the foundation for further research in the future. This paper designs a remote temperature monitoring system based on arm development board. The system uses the mature arm technology as the processing chip, as well as now widely used singlewire temperature sensor DS18B20 as the temperature sensing device, to obtain realtime and accurate temperature information. This paper describes the development process of the embedded operating system and also describes embedded chips arm series and embedded system – Linux. This thesis describes the method of armlinux cross piler and explains the use of the arm device management mode and pipeline files. This paper also tells the way to use Makefile and the way of data transmission between CGI program and pipeline file. Overall, the paper explains the embedded Inter from basic works, it describes the embedded lowlevel development process, a majority of novice students can read it. Another design focus of this design is web interface, we need know the way of using html language. To make the interface more beautiful, we can use same scripting language, in this design, we use Javascript. Key words: Embedded operating system, CGI program, Html language 重慶大學(xué)本科學(xué)生畢業(yè)設(shè)計(jì) （論文） 目錄 III 目錄 摘要 .....................................................................................................................................
