| Charging set is the core part for DC600V/110 power supply, Its stability and reliability directly affect operation security of train. During the period of refreshing the check of charging set, because of no refresh the equipments that the machine carries on an examination to the DC600/110 Vs exclusively, the charging set need be dismounted and assembled frequently when repair, which will increase working intensity, and make against repair efficiency; therefore, to design and develop a Specialized DC600/110V charging set examine test stand is needed to meet charging set examine.This text makes use of the MATLAB software to refresh machine to go against to become main electric circuit transformer original side,vice- side electric voltage,IGBT work time,refresh the machine exportation electric voltage to input electric voltage in the dissimilarity under of the exportation carry on imitate really. Pass to imitate really to the railroad department [2006] on the 142th in refresh the machine check to fix and experiment a method of the request carried on a verification. Pass to refresh machine to go against to become the main electric circuit and the work principle to carry on analysis to the DC600/110Vs.Studied traveler railroad train well to refresh the network principle and PLC of the machine up to the control that refreshes machine. Developped the intelligence type auto-recharged machine of the use PLC control .On trial pedestal of develop from power supply part, load part, operation control part, experiment the software part, the exterior importation output five parts to constitute, is gather electricity control system, microcomputer measure and control system as integral whole of new experiment. Experiment the set adoption a design to measure to control the system and the function good electronics dollar spare part goodly, promise an on trial examination a result of stability, credibility. The on trial data that passes automation collects with the processing mean, raise to refresh machine examination homework level consumedly.The author considered to refresh machine well in the control mode on traveler railroad train, make the on trial set operation personnel's test method for develop more, as long as will experiment to refresh machine with experiment set to press to request to link to like to lead line after, manipulate the keyboard and mouse, experimenting set can pass on trial procedure then, the automatic completion carries on an examination to various function index signs that refresh machine, recording various examination data automatically, and carry on judge to the function that refreshes machine according to the examination data autoAfter refresh the machine experiments a pedestal a creation completion, Be carry on try movement in the Chengdu vehicular branch three months. The exploitation should experiment set to the Chengdu vehicular branch inside need to check to fix of more than 100 sets refresh machine to carry on a test. Test the enunciation should experiment set automation degree high, operate vivid, use in brief convenient, function stability, meet the related request of the railroad department, come to an a design a purpose.
