飛機(jī)電網(wǎng)故障時(shí)，機(jī)載電氣盒必須在延遲時(shí)間內(nèi)切斷電網(wǎng)，保護(hù)機(jī)載設(shè)備。采用AT89S52設(shè)計(jì)的電氣盒測(cè)試儀能夠測(cè)試電氣盒保護(hù)功能，測(cè)量延遲時(shí)間。實(shí)際應(yīng)用結(jié)果表明，該測(cè)試儀具有測(cè)量準(zhǔn)確、可靠性高、成本低等優(yōu)點(diǎn)。
Abstract:
The helicopter-electrical-box must shut off the helicopter power，protect the equipments of the helicopter when the helicopter power is failed.The tester for the helicopter-electrical-box based on AT89S52is used for testing the protect-ing function and measuring the delay time.Application results show this tester has some advantages,such as accurate mea-surement,high dependability,economical cost etc.
