| Combines with the technologies of network communication, monitoring and embedded technology, the embedded system based on Internet/Intranet is designed for a remote monitoring, controlling system based on Internet/Intranet by way of being embedded into the object to be monitored. First of all, with the embedded Internet/Intranet technology, this paper summarizes primary application in life and the latest development at present. And then the well-known TCP/IP protocol is simply presented. The paper analyzes the difference of embedded TCP/IP protocol and standard TCP/IP protocol and gives the basic designed principle. Also in this paper, the communication protocol hierarchy, general architecture and each protocol' s main processes are discussed in embedded TCP/IP protocol, and the practical applied embedded TCP/IP protocol is made out. At last, on the basis of the practical example of LIANYUAN' S control network and data network integration technology, this paper brings up a new monitoring and control system construction frame that based embedded TCP/IP protocol, taking use of the technology of embedded network. Also in this paper, designs and implements it with the use of related technologies of hardware and software, and discusses and implements the three main questions: the design of the front equipment of collecting; the managing and scheduling technology of the multi communication threads in communicating module of monitoring and control system; the data processing. Because of its advantages several problems of the traditional system architecture are solved. This scheme can access and manage real time miscellaneous resources reliably and accurately in monitoring environment, thereby achieve a better performance. |
