The invention relates to the technical field of
avionics, in particular to a multi-channel ARINC (aeronautical radio incorporated) 700
bus monitoring device and a realizing method thereof. The device comprises an industrial
personal computer, a
bus adapter and
bus access equipment, wherein a multi-channel ARINC 429 bus module is arranged in the industrial
personal computer; the bus adapter comprises a main board, a self-checking module, a power
supply management module and a
switch matrix module; and the bus access equipment comprises an
aviation bus
distribution frame and a ZIF (
zero insertion force) interface.
Control data and bus data are switched between the industrial
personal computer and the bus access equipment through the bus adapter; the industrial personal computer transmits an instruction
package to the bus adapter to finish instruction loading through the ZIF interface; a monitoring circuit is mounted on an
aviation bus, so that the bus data can be read; when other buses need to be monitored, by only updating the loading instruction, the switching of the channel can be finished, which is convenient and rapid; the speed requirements in an automatic measuring and
monitoring system can be fully satisfied; the testing time is greatly reduced; and the problem of
wasting a large amount of bus channels in a complex
avionics system is solved.
