Abstract

The invention belongs to the field of automotive electronic product testing technology, and particularly relates to a novel test system of an ignition coil. The test system comprises an industrial control computer system and a signal drive unit. The industrial control computer system comprises a high-speed data collection card. The signal drive unit comprises an ignition module. A signal collection unit is provided with a signal pre- processing module. One end of the signal pre- processing module is electrically connected with a high-voltage detection electrode, and the other end of the signal pre- processing module is divided into three paths to output, wherein two paths are electrically connected with the high-speed data collection card, and another path is electrically connected with the signal processing module after passing through a spark current sampling module. One path of signal of the ignition module is electrically connected with the signal processing module after passing through a primary current sampling module. The signal processing module is connected with the high-speed data collection card. The test system aims to solve the problems that the dynamic parameters of the ignition coil cannot be directly measured because the test system of the current ignition coil has structural design shortcomings, the test waveforms and the test data which are manually collected and read have errors, and the test data cannot be permanently stored.
