一种双模通讯的外系统等效器设计
Design of external system equivalent device based on dual-mode communication
摘要
Abstract
To overcome the problem of poor communication stability between the external system equivalent devices while the aerospace craft performing the ground simulation tests,an external system equivalent device based on PCI and USB commu⁃nication technology was designed. This system takes FPGA as the central control unit,and its circuit design is based on chips FT245RL and PCI9054 to accomplish the information transformation to the upper computer. The outputs of PCM signal and 10 RS 485 signals were realized. Long⁃term test results show that the signal output is stable,and can satisfy the task requirements. This system was applied to a certain aerospace measurement system.关键词
