Lots of test projects of consume a large amount of time and need real-time monitoring. Aiming at the above problems

the spaceborne FOG automatic test system adopts program of controller area network（ CAN） and FPGA is proposed

which bases on Verilog designing collecting lower computer（ PC） program and based on Microsoft foundation classes（ MFC） of VC6.0 designing upper PC program. The system can real-time acquire and automaticly store FOG data. Meanwhile

monitor working voltage

current and environmental temperature of FOG. In case of overvoltage

undervoltage

over current and abnormal temperature

the system opens fault protection function and alarm. The system achieves expected technical index

and successfully guarantees the test go well.
