Problems solved by technology

Due to the fact that the equipment under test may have problems in the power variation test environment, it may be random, and it is completely subjective to judge that there may be missed detections, and it often takes more testing time to confirm that random failures occur or no longer occur. , high cost of testing

Embodiment Construction

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] The structural diagram of the automatic test system for changes in the power supply of automobile electrical appliances of the present invention is as follows: figure 2 As shown, it includes a control device (such as a PC), a program-controlled power supply, a test box, and a device under test. Through the control device, the program-controlled power supply generates a power supply test waveform, and the test box (Test Box) generates a switch associated with a power supply change. Signal, on this basis, has also increased...

Abstract

The invention provides an automatic testing system for automobile electrical-appliance power supply variation, and a testing method thereof. The automatic testing system comprises control equipment, aprogram-controlled power supply, a testing box, tested equipment, and information collecting equipment. Through the control equipment, the program-controlled power supply generates a power supply variation testing waveform, the testing box generates a signal associated with the power supply variation testing waveform, and the power supply variation testing waveform and the signal are applied to the tested equipment; and by identifying information from the information collecting equipment, the information output by the tested equipment can be analyzed in real time, and whether the tested equipment is in a breakdown state or not is judged automatically.

Description

technical field [0001] The invention belongs to the field of electric performance detection of automobile electric appliances, and in particular relates to an automatic test system and a test method for the change of electric power supply of automobile electric appliances. Background technique [0002] The power variation test is one of the electrical performance tests of automobile electrical appliances, and is an indispensable part of the enterprise standards of automobile factories. In this experiment, the power waveforms under various working conditions that automobile electrical appliances may encounter during use are simulated. Under the conditions of various test waveforms, the equipment under test should not be affected by normal operation or have acceptable functions. reduce. Moreover, different car manufacturers have different specific standards for power supply variation experiments, and the required waveforms are mostly different. The programmable power supply ...
