Research And Development Of Intelligent Building Control Network Based On Ethernet Tcp / Ip Protocol

Aimed at the demand of the Intelligent Building' s development, and with the direction of the Ethernet technology, a new Intelligent control method is proposed in the dissertation after that Ethernet technology is compared with other control systems. In the dissertation that Winbond 77E58 controls RTL8019AS is adopted. So the parameter and variable can be send to the servers conveniently.This dissertation consists of five chapters, in which the primary contents and conclusions are displayed as follows.In chapter 1, it concisely introduces the common functions and structure of the Intelligent Building, as well as the principles and basis when designing actual system. Besides, it emphatically states the selection of the system.Chapter 2 bewrites rudimental knowledge and frame of the TCP/IP protocol.Chapter 3 aims at the core of hardware of the system. Firstly, it analyses the working rinciple of the network card with RTL8019AS. Secondly it states the connection between CPU and the other equipment.In chapter 4, it mostly shows the software. In the software,the most important is the actualize of transition between Ethernet and 8 bit SCM series joint.Chapter 5 is focus on how to make the system works well. Data wills be drop by Ethernet,so using the 8 bit CPU, slide window is actualized.In the last chapter of the dissertation, it showes a whole appraisement of this system from application sites and design characteristics, at the same time, it also points the deficiency of the system with an eye to development. Simultaneously, the paper attaches some related instances convient for reference.
