CIRCUIT ANOMALY DIAGNOSIS DEVICE, CURRENT GENERATION DEVICE, AIRCRAFT DEPLOYABLE BODY EJECTION DEVICE, AIRCRAFT AIRBAG DEVICE, AND AIRCRAFT CUTOFF DEVICE

摘要

[Problem] Provided are a circuit anomaly diagnosis device that can simply and easily diagnose an anomaly in a circuit, a current generation device including the circuit anomaly diagnosis device, an aircraft deployable body ejection device including the current generation device, an aircraft airbag device including the current generation device, and an aircraft cutoff device including the current generation device. [Solution] A circuit anomaly diagnosis device 110 comprises a computation unit 1, an inspection power supply 2, a rectifier element 3, overcurrent prevention resistors 4 and 5, a voltage amplifying unit 6, a voltage reading unit 7, and a light emitting unit 8, and diagnoses an anomaly of a circuit at a pre-set time (including an initial loading time) or every predetermined time. The circuit anomaly diagnosis device 110 diagnoses (judges) a normal state when a voltage value is in a range of greater than or equal to a first voltage value V₁ and less than or equal to a second voltage value V₂, which is set in advance as a voltage value range indicating that the circuit is normal; a short circuit state when the voltage value is less than the voltage value V₁; and a disconnection state when the voltage value is greater than the voltage value V₂.
