| Abstract: |
| In order to solve the problem of simulating the DC power supply
system of aircraft in a variety of extreme cases for the airborne equipment
development and maintenance, an aircraft DC power supply simulation equipment s
ystem based on virtual instrument technology is proposed in this paper, based on
the analysis of aircraft DC power supply system power mode and power supply log
ic. The hardware system is mainly composed of USB bus based Compact DAQ modular
data acquisition platform of NI Company and dedicated DC circuit breakers produc
ed by E-T-A Company and Airpax Company. The software system is designed based
on LabView platform, state machine and producer-consumer model architecture. An i
mplementation of the instantaneous power failure test is presented. The actual re
sults show that the developed equipment can realistically simulate power supply m
ode of the aircraft DC power supply system, the power logic is correct, the inst
antaneous power failure test is completed. The power supply system features
fast response time, high reliability, and good scalability. |
