Software Optimization And Perfect Based On UN-150ZB Mobile Rail Flash Butt Welding

According to the12th Five-Year Plan of the railway construction, the newly built railway lines will continue to increase and the total size of the production of new lines will be more than20,000km. Therefore, there are more and more rail flash butt welding machines in the new line construction and old lines maintenance. How to ensure the quality reliability and the fault rapid detection of rail flash butt welding machine will be a very serious problem. In the domestic, the site flash butt welding machines Widely used belongs to the AC welder at present, Both of domestic welder and imported welder have many problems, such as high requirements for maintenance personnel, long cycle of troubleshooting And with the increase in the number of welded joints, the status of components will change, welding quality is difficult to be ensured. To this end, how to improve and optimize the computer monitoring system of UN-150ZB rail flash butt welding machine which developed by Chengdu Iger technology is the purpose of this thesis.The present paper had carried on following work:(1) the displacement of intelligent calibration module was established, which could achieve displacement calibration automation by host computer,(2) input signal detection module and welding machines boot failure diagnosis module were developed, which was easy for first-line maintenance personnel to inspect and maintain the equipment.(3) Voltage calibration and speed calibration line display module were developed on Computer Control System and the voltage, speed calibration of the PLC control software were improved:(4) pressure, impedance and the upset detection module was established to monitor the welder state and give Maintenance recommendations to personnel for the welding quality:joint number module was researched to Prompt number of joint.The practical application shows that the welding machine’s overall performance was enhanced and the level of automation welding machine was improved after the completion of the monitoring system, the good man-machine interface and good operation performance reduced maintenance personnel of difficulty greatly and insured the construction progress on the way.
