Airplane Electronic Device for Interlocking Failure Detection and Elimination of Each Board Unit

Board unit by interworking fault detection and exclusion system of the present invention avionics is received periodically through a plurality of input and output board 200 and the serial check the interlock state, and receives the fault status of each input and output board 200, each input and output firmware program (120), each input and output boards 120, to determine a rule if the board 200, the input and output boards linked based on the self-check result of each input and output board 200 with a defect to failure with 200 status information and fault receives the information by the monitor in real time, by including the operation program 120, the processor board 100 with the performing the operation according to the scenarios when the output fault fault detection and exclusion, the board operations per unit continued to interoperability and operational reliability but also of non-maximum rule out the possibility that the output is generated to implement the features that are greatly improved.
