摘 要:針對目前對HXD3、HXD3C、HXD1B、HXD1C型電力機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測試數據進行分析、處理,并對存在故障的變流器進行故障診斷。利用CAN總線易于擴展、結構簡單的特點,改變了以前診斷系統功能單一、不易擴展等缺點,便于系統的升級和節約重復設計的成本。

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
