  1. Firstly, this paper makes a detailed study on the field control bus system ( pcs ), including the characters of pcs by comparing fcs and dcs, model networking of pcs and several popular field bus, then put forward a question for discussion combining embeded internet technology and field bus and measure and control networking model based embeded internet technology is constructed. secondly, it studies embeded system including the core of hardware ? mbeded microprocessor and real time operation system. thirdly, the method of realizing embeded internet is discussed for emphasis, and difficulty of ehernet application in industry measure & control system is analysed. an instance of measure & control networking system based embedded ip is given. finally, the author designed a networked remote video surveillance system based embedded web server, c / os - ii is sacled and ported into the embedded microprocessor at89c51. based on the c / os - ii rtos, tcp / ip protocol suite and application program is designed in detail. the system w orks well that improves that the embedded internet technology will be widely used in modern measure & control networking system and has extend values

    本文首先分析了現場總線系統( fcs )與傳統集散控制系統( dcs )相有的特點、 fcs的網路體系結構,介紹了幾種流行的現場總線,提出了將嵌入式internet技術結合現場總線構建現代測控網路的課題;在此基礎上,構建了基於嵌入式internet技術的測控網路結構模型;深入研究了嵌入式系統的核心硬體?嵌入式微處理器,通過對普通操作系統,描述了嵌入式實時操作系統的特點;重點研究了實現嵌入式internet的四種實現方法,並分析了以太網在業測控系統中應用的難點,給出了一個基於嵌入式ip的網路測控系統實;最後,研究與設計了一個基於嵌入式web服務器的遠程網路視頻監控系統,該嵌入式web服務器利用目前成熟的嵌入式實時操作系統c / os - ,通過對c / os -進行適當的裁剪、與移植,在at89c51嵌入式微處理器上實現了tcp / ip協議棧及應用程序,系統的成功運行證明了本文研究成果的有效性,也表明嵌入式internet技術在現代測控網路系統中有廣闊的應用前景和推廣價值。
