Abstract

The invention relates to a train noise weighting current testing and processing method. The method comprises the following steps: 1) mounting current probes on each current feeding module; 2) transmitting multi-path current signals received from the current feeding modules to a multi-channel summator by the current probes; 3) processing the received multi-path current signals by the multi-channel summator, and outputting a total current signal; 4) transmitting the total current signal output from the multi-channel summator to a data recorder; 5) acquiring and recording the received total current signal by the data recorder, and outputting the acquired data; and 6) according to the standard demand, editing software, completing data processing on the acquired data output from the data recorder, and finishing the test. The train noise weighting current testing and processing method effectively solves the noise current testing problem for asymmetric marshalling and asymmetric power unit vehicles, and can more visually and effectively obtain the test result.

Description

technical field [0001] The invention relates to a train noise weighted current test and processing method, which belongs to the technical field of test and data processing. Background technique [0002] At present, current sensors and data recorders are generally used in noise current testing of urban rail vehicles to collect vehicle cable signals. Symmetrically organized trains can be in accordance with standard requirements, and the collected data can be post-processed through software. However, with the emergence of more and more vehicle projects with asymmetric marshalling and power unit asymmetry in recent years, and the test of such vehicles is not clearly defined in the standard, the data collected and done according to the original test method The data processing can no longer meet the requirements. At this time, it is necessary to study the vehicles with asymmetrical marshalling and asymmetrical power units and formulate new test programs and data processing methods...
