The invention provides an electromechanical
management system bus monitor which comprises a portable reinforcing
machine, a modular expansion cabin is arranged at the bottom of the portable reinforcing
machine, four PCI
bus slots are integrated in the modular expansion cabin, and
bus simulation cards with four PCI interfaces, namely HB6096, ARINC825, 1553B and AFDX, are respectively mounted in the four PCI bus slots; the portable reinforcing
machine is further provided with a
signal interface box used for connecting the interfaces of the four PCI bus
simulation cards with an
airplane interface. Electromechanical monitoring
software is configured in the portable reinforcing machine and comprises a real-time monitoring module, a data playback module, a protocol analysis module and an interface setting module. According to the bus monitor, real-time monitoring and
fault analysis of various electromechanical buses, bus
data recording and data playback analysis can be implemented on an outfield aircraft, and the fault diagnosis efficiency of an aircraft electromechanical
management system can be improved.
