Failure information transmission apparatus

摘要

A failure information transmission apparatus includes a transmission circuit and a reception circuit. The transmission circuit transmits a plurality of pieces of failure information related to a plurality of failures as pulse signals different from one another via the same transmission path. The reception circuit receives the pulse signals transmitted by the transmission circuit via the same transmission path and identifies the failure information based on the pulse signal received. If the plurality of failures occurs at the same time, the transmission circuit transmits preferentially transmits failure information with higher priority of transmission.

1. A failure information transmission apparatus, comprising:
a transmission circuit that transmits a plurality of pieces of failure information related to a plurality of failures as pulse signals that are different from one another via the same transmission path; and a reception circuit that receives the pulse signals transmitted by the transmission circuit via the same transmission path and identifies the failure information based on the pulse signal received, wherein: the transmission circuit transmits preferentially transmits the failure information with higher priority of transmission, if the plurality of failures occurs at the same time; the transmission circuit transmits the plurality of pieces of failure information as pulse signals different in frequency from one another; and the transmission circuit transmits the plurality of pieces of failure information as pulse signals which become higher in frequency as priority of transmission becomes higher.
