Abstract

The invention discloses an automobile electronic and electric appliance test system. A method comprises the following steps: acquiring a CSV file of an original waveform signal from external equipmentthrough a USB interface to generate an original waveform signal; amplifying the original waveform signal to generate a target waveform signal, and testing the target waveform signal; if the test standard is met, enabling the target waveform signal to be inputted into an automobile electronic appliance for testing, thereby solving the problems that in the prior art, the automobile electronic appliance is high in test cost, complex in operation and the like. The invention further provides an automobile electronic and electric appliance testing method and device and a storage medium.

Description

technical field [0001] The invention relates to the field of electrical testing, in particular to a testing method, device and storage medium for automotive electronic appliances. Background technique [0002] The rapid development of the automobile industry has led to the development of many related industries. With the development of automobile electronics, the electrification and informatization procedures on automobiles are getting higher and higher, and there are more and more electronic devices on automobiles. The power supply system is composed of a generator and a battery. Due to the inherent characteristics of each device, the device will affect the power supply quality of other automotive electronic devices when it is working, such as voltage changes on the line. Therefore, if the electronic equipment of the power supply system fails, it will affect the normal power supply of other automotive electronic equipment, resulting in abnormal operation of other equipment,...
