Embodiment Construction

[0015] Such as figure 1 As shown, the present invention includes: a main control computer 1, a high-speed data collector 2, an analog power amplification module 3, a digital power amplification module 4, an analog conditioning module 5, a digital conditioning module 6, a control unit TCU7, and a chopper 8. The main control computer 1 and the high-speed data collector 2 form a two-way interconnection through the PCI bus. The high-speed data collector 2 consists of two high-speed data acquisition cards to form a multi-channel serial-parallel data collector. The high-speed data collector 2 provides analog and digital data Channel output and input, the analog signal is output to the analog power amplifier module 3 through the analog channel, the digital signal is output to the digital power amplifier module 4 through the digital channel, and the analog power amplifier module 3 and the digital power amplifier module 4 transmit the signal through their respective multi-channels Inpu...

Abstract

The visible complex test system for main metro train loop includes host computer, high speed data acquisition unit constituting bi-directional interconnection without host computer and providing both analog and digital I / O signals, analog and digital power amplifier modules, control unit TCU to accept the signals from the analog and digital power amplifier modules, chopper with feedback channel to TCU, analog and digital processing modules to process signals from TCU, analog and digital channel for the processed signal to be returned to the high speed data acquisition unit with the control signal being output to the host computer to realize the analysis and evaluation of the chopper characteristic. The present invention provides the decision reference for the safety estimation of metro train.

Description

technical field [0001] The invention relates to a visualization system for testing in the technical field of power electronics and electric transmission, in particular to a visualization system for comprehensive testing of a main circuit of a subway train. Background technique [0002] The subway and light rail as urban rail transit are in the development stage in our country, and the construction tasks are very heavy. There are still many high-tech solutions to be solved in order to promote the development of urban subway and light rail transportation in my country. Since Shanghai introduced subway trains and their control technology from Germany, the new traction technology of subway and light rail trains has seen a new leapfrog development in my country. The key technology that constitutes the traction system of subway and light rail trains is actually the chopper. The main circuit technology of the component. The test and evaluation of the comprehensive performance of th...
