    摘  要:針對(duì)目前對(duì)HXD3、HXD3C、HXD1B、HXD1C型電力機(jī)車變流器故障診斷需求以及它們之間的性能差異,提出使用CAN總線將各功能模塊連接起來,并通過分析處理軟件對(duì)測(cè)試數(shù)據(jù)進(jìn)行分析、處理,并對(duì)存在故障的變流器進(jìn)行故障診斷。利用CAN總線易于擴(kuò)展、結(jié)構(gòu)簡(jiǎn)單的特點(diǎn),改變了以前診斷系統(tǒng)功能單一、不易擴(kuò)展等缺點(diǎn),便于系統(tǒng)的升級(jí)和節(jié)約重復(fù)設(shè)計(jì)的成本。

    Abstract: Main inverter test bed is mainly used to test the comprehensive performance of the converters of HXD3, HXD3C, HXD1B, HXD1C electric locomotives, and test the performance of the converter CI/TCU control unit. This paper proposed to connect each function module with CAN bus and to analyze and process test data, orderly to diagnose the faults of converters through the analysis and processing software. The CAN bus is easy to expand and its structure is simple, which overcomes the shortcomings of the previous diagnosis system including single function, difficult to expand. The new system is easy to update and save the design cost.
    Key words: CAN bus; converter; fault diagnosis; performance test
