Abstract

The invention discloses a dynamic ageing monitoring system and a dynamic ageing monitoring method for a switch mode power supply of a locomotive. The dynamic ageing monitoring system comprises an industrial control personal computer (PC), a peripheral component interconnect (PCI)-general purpose interface bus (GPIB) card, a PCI system, a GPIB system and an interface unit, wherein the PCI system comprises a programmed switch card and a programmed data acquisition card; the GPIB system comprises a programmed power supply and a programmed load; the industrial control PC, the programmed switch card and the programmed data acquisition card are connected with the PCI-GPIB card through PCI buses; the PCI-GPIB card performs transformation between a PCI protocol and a GPIB protocol; and the programmed power supply and the programmed load are connected with the PCI-GPIB card through GPIB buses. The technical problems that the conventional ageing monitoring system has low universality, dynamic parameters of a power supply board to be detected in the ageing process are lack of detection and result judgment is lack of data support can be well solved, so a dynamic ageing monitoring platform is provided for a switch mode power supply single board of the locomotive.

Description

technical field [0001] The present invention relates to a kind of computer test monitoring 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, that is, the instrument can be controlled by software programming, and what you see on the software side is the virtual instrument) technology monitoring system and method. 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 supply boards are basically the same, but different input v...
