The Research And Design Of New Relay Star Testing System

This paper is based on a project of department of some system enginerring, aiming to realize a communication and control between PC computer and artillery at the same time implemention of information share of the network by ethernet interface.According to the demand of the project,a system integration module is advanced and designed which include DSP,USB interface,PCI interface,ethernet interface and other analog converter interface.system integration module look upon DSP as its core,integrating the PCI interface and USB interface as its communication bus with PC computer,using netcard chip to transmit the network information after processed and receive the network information before processed.Thus,When information from network arrived,system integration module will process the signal and transmit it to PC computer by PCI or USB;ohterwise,when PC computer send command to the system integration module,it process the command and driver periphery device by analog converter.The implemention of task of system integration module's software include the development of ethernet driver software,PCI driver software,USB firmware and other analog converter software.This artile has finished the whole hardware design of the system integration module.Besides above hardwae design, we research the method of the reailization of PCI software and ethernet software,further more,the communication between PC computer and system integration module has been realized by USB interface.
