Abstract

The invention relates to a general-purpose automatic test method for a locomotive switching power supply, and general-purpose automatic test system, and comprises a test control system, a programmable power supply unit, a programmable DC load unit and a programmable data acquisition unit, wherein the programmable power supply unit is connected with the test control system through a GPIB bus and provides excitation for the tested switching power supply; the programmable DC load unit is connected with the test control system through the GPIB bus and provides a load for the switching power supply to be tested; and the programmable data acquisition unit is connected with the test control system through the GPIB bus and acquires responses of the tested switching power supply. The output voltage, voltage regulation factor, load regulation factor and the like are tested by logging in virtual instrument software on a personal computer. The invention can well overcome the defects of insufficient compatibility, high complexity and low reliability of the test system in the prior art, and has the advantages of automation, general purpose, convenient operation and reliable performance.

Description

technical field [0001] The present invention relates to a kind of computer measuring and testing technology, especially a kind of based on GPIB (General Purpose Interface Bus, a kind of instrument control bus) bus technology and virtual instrument (Virtual Instrument, virtual instrument) related to rolling stock switching power supply , that is, the instrument can be controlled by software programming, and what you see on the software side is a virtual instrument) technology general automatic test system. Background technique [0002] Switching power supply: Switch Mode Power Supply refers to a DC stabilized power supply in which the device used for voltage adjustment functions operates in a switching manner. The locomotive switching power supply board is an important part of the locomotive control system, and it is also a large and indispensable part, providing stable and reliable working power for other equipment and boards. The functions of different switching power supp...
