Local Design and Test of Ground Measurement,Control and Communication System
External system equivalents are needed to simulate various control signals and measurement parameters in the test and experiment phase of spacecraft such as rockets and satellites.However,in recent years,foreign countries have implemented technology blockade,in order to solve the problem of"jam neck"in the chip field in China,an innovative external system equiva-lent is proposed with domestic FPGA as the control core,domestic power chip as the power supply core,domestic gigabit Ethernet and four-channel transceiver active optical module as the transmission core.Under the test of high and low temperature test,vibra-tion test and electromagnetic interference test,the system has good real-time performance and high reliability,and the communica-tion speed in optical fiber link can reach 1.25Gbit/s,which meets the requirements of the project and achieves the purpose of local-ization,and has been successfully applied in a certain type of equivalent test system.
