Embodiment Construction

[0015] like figure 1 As shown, the present invention includes: a main control computer 1, a high-speed data collector 2, an analog power amplifier module 3, a digital power amplifier 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 dual high-speed data acquisition cards to form a multi-channel serial-parallel data collector. The high-speed data collector 2 provides two types of analog and digital data collectors. Channel output and input, the analog signal is output to the analog power amplifier module 3 through the analog channel, and the digital signal is output to the digital power amplifier module 4 through the digital channel. It is input to the control unit TCU7, and the signal generated by the control unit TCU7 of the central logic unit of the main ...

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 power transmission, in particular to a visualization system for comprehensive testing of the main circuit of a subway train. Background technique [0002] As urban rail transit, subway and light rail are in the development stage in my country, and the construction tasks are very heavy. There are still many high-tech technologies to be solved to promote the development of my country's urban subway and light rail transportation. Since Shanghai introduced the subway train and its control technology from Germany, the new technology of subway and light rail train traction has developed by leaps and bounds in my country. The key technology that constitutes the subway and light rail train traction system is actually the chopper. Main circuit technology of components. Testing and evaluating the comprehensive performance of the main circuit is on...
