A LabVIEW pulse t system and method

Abstract

The invention discloses a LabVIEW pulse test system, which comprises a vehicle-mounted entertainment system control module, a PC upper computer, a pulse generator control module and a high-speed bipolar power supply. The invention also comprises an image recognition module and a voice recognition module respectively connected with a vehicle-mounted entertainment system control module, a PC host computer, an automatic alarm module and a report generation module respectively connected with the PC host computer. The PC upper computer uses LabVIEW to establish serial communication with the vehicle-mounted entertainment system control module. The image recognition module is used for comparing the pulse picture template of the vehicle-mounted entertainment system with the taken pulse picture; The voice recognition module is used for collecting the output pulse waveform and judging whether the output pulse waveform meets the playing signal amplitude and within the frequency tolerance range. The automation degree of arbitrary pulse waveform test is improved and the test efficiency is greatly improved by using the technical scheme.

Description

technical field [0001] The invention relates to the field of automatic testing, in particular to a LabVIEW pulse testing system and method. Background technique [0002] Arbitrary pulse generators are widely used in the testing work of the automotive electronics industry to simulate the power supply changes during the starting process of the car. At present, some more traditional technical means are still used in arbitrary pulse testing, relying on manual testing. The manual test is mainly to transmit the arbitrary pulse waveform to the high-speed bipolar power supply for testing through the arbitrary function generator. The following disadvantages: [0003] 1) The current test position of the waveform cannot be marked, but the current output voltage is displayed quickly, which is not easy to observe; [0004] 2) It is not possible to intercept a section of the waveform for testing; [0005] 3) When an abnormality occurs, it will not be automatically identified and the o...

The manual test is mainly to transmit the arbitrary pulse waveform to the high-speed bipolar power supply for testing through the arbitrary function generator. The following disadvantages:

[0005] 3) When an abnormality occurs, it will not be automatically identified and the operation will be suspended, and the test needs to be stopped manually;

[0006] 4) Cannot automatically output test results
