The Based Rabbit2000 Network Traffic And Its Implementation

Currently, our country is taking great effort to develop Digital TV(DTV) industry. As DTV system's key components, front-end equipments are characteristic of various type, large amount and many parameters and need centralized management. For the demand of the network communication in the DTV front-end system, design the network communicationg system.It can manage the devices and trasmit the date from server controller in the DTV front-end system to bottom devices.The design procedure and application method of the Rabbit2000 network communication system were introduced in this paper in detail.This paper was divided into several main parts as follow:One,according to the development of the DTV,the method of designing the communication system was needed.Two,based on the necessary functions of the system,introduce the desing project of the system,and regulate the content of the network communication protocol.Three,introduce the hardware design method of the network communication based on Rabbit2000.In addition ,the detailed hareware debugging was given at lase.Fore,accoding to the chosen project,system's software programmed and the design method was described.The Dynamic C ,the software-module flow charts were presented.Five,introduced the added function of DHCP in the system,analysed the protocol and given the chart of the software.Finally,realized the network communication based on Rabbit2000.Some problems occurred in the debug procedure and respective solutions were given for farther understood.
