Title:
NON-CONTACT HANDHELD MULTI-STATION AUTOMOBILE HIGH-VOLTAGE IGNITION COIL FAULT DETECTOR
Document Type and Number:
WIPO Patent Application WO/2021/046931
Kind Code:
A1
Abstract:
A non-contact handheld multi-station automobile high-voltage ignition coil fault detector, comprising a sensing antenna, an electromagnetic field signal amplification circuit, an ignition signal processing circuit, and a display circuit. An output end of the sensing antenna is connected to an input end of the electromagnetic field signal amplification circuit, and an output end of the electromagnetic field signal amplification circuit is connected to an input end of the ignition signal processing circuit. An output end of the ignition signal processing circuit is connected to an input end of the display circuit. The sensing antenna is used for sensing an electromagnetic field signal generated when the ignition coil is ignited. The non-contact handheld multi-station automobile high-voltage ignition coil fault detector facilitates a user to compare the displayed ignition signal detection data so as to determine the fault of the ignition coil, namely, non-contact rapid induction is adopted, and the ignition coil does not need to be disassembled, so that the ignition coil with abnormal work can be rapidly detected under the condition of saving time and cost.
