Remote Monitoring System Based On Embedded Internet Design

With the rapid development of Internet, High speed information transmission and resource sharing comes to be true. Internet brings expediency to our living. Embedded system is widely used in electronic products, smart instruments and control equipment. It is an inevitable trend that the embedded technology and the Internet will combine together. The long-distance supervisory and control system are researching hot spot in industrial automatization fields at present. Internet-based long-distance supervisory and control system is the combination of information network and control network. It completes the monitoring and control tasks based on network, by which the monitoring and control range can be greatly extended, and moreover the control technology will be more networkized, more distributed and more open.This paper works over the long-distance supervisory and control system based on embedded Internet, and puts forward a kind of long-distance supervisory and control system of B/S pattern which is based on ARM microprocessor and Linux OS.Firstly, this paper introduces the embedded system, including embedded microprocessor, embedded OS and embedded Internet, analyzing the present status and development trend of the system. In Chapter two, after introducing several schemes of embedded Internet, the whole project and total frame is given. Chapter three introduces each module's function and electric circuit design. In Chapter four, Linux is transplanted on hardware platform. Chapter five discusses a few key techniques involve by embedded web server, including HTTP protocol, HTML form, CGI and Socket network programme, in the end, we embed a web server in the system. Chapter six describes the realization of long-distance temperature-collection supervisory, long-distance sound-play control and web pages. In the last part of this paper, the research work of the paper is summarized and the future development and the application foreground of long-distance supervisory and control system are analyzed.
