[0002] The aircraft engine is the heart of an aircraft, and the aircraft ignition system is one of its most important components. The ignition system refers to the ignition source system used in the main combustion chamber and afterburner. It converts the direct current or alternating current in the aircraft into high-voltage electricity, which is then released through ignition cables and electrodes to produce a spark, ensuring sufficient energy for the spark to directly ignite the air-fuel mixture in the engine's combustion chamber. Online detection of the engine ignition system spark frequency determines whether the system is functioning correctly by measuring the spark discharge frequency. Existing multi-channel online spark discharge frequency detectors include an ignition device, sampling cable, first sampling circuit, second sampling circuit, frequency measurement channel isolation circuit, isolation processing circuit, preset circuit, data processing control circuit, display circuit, power module, power control circuit, signal indication circuit, self-test circuit, photoelectric sensor, electrode, and high-voltage cable.
