Design And Implementation Of Tamper Automation Control System

After the railway running for a period of time, the geometry shape of the railway will be changed because of the influence of kinds of factors, and the train speed and safety will be seriously influenced, thus the railway must be maintained and amended regularly. In recent years, due to the rapid development of our country railway undertakings, the growth of the total mileage of railway year by year, the continuously improvement of the train speed, the increase of the density of the train, the higher requirements of the efficiency and precision of railway maintenance are put forward. Tamper as the most basic track maintenance equipment and most widely used in our country, therefore improving the working efficiency and control precision of tamper has important significance to raise the railway "skylight" time utilization and ensure the speed and safety of the train.In order to ensure the high speed railway tamping effect, tamper almost uses "precision measurement and tamping" method to finish railway tamping work. Using track inspection car measure railway parameters accurately, by these measuring data to guide tamper finish the precision tamping work. Tamper manual control method operation is simple, applicability, widely used in accuracy tamping working. However, because the accuracy tamping working signals to be manually input by operator, so the operator’s workload is big, that is easy to introduce human error. In this thesis, the author use modern computer control technology, and design automatic control system to replace the process of the manually input of the track lifting and lining value, realize the automation of tamping pearling operations, avoid the introduction of human error, reduce the work intensity of operator, and improve the accuracy and efficiency of tamping operations.Firstly, this thesis introduces the tamper control process and tamper lifting and lining electrical control system. Then introduces the interfaces between automation control system and tamper is introduced. At last, introduces the overall design of the system is given. The control system consists of the work control software and slave operations controller which constitutes a master-slave relationship. Lower machine is controlled by work control system to finish outputting tamper’s control signals and collecting tamper work data and so on. The thesis completed the tamper work control circuit board design, which is based on C8051F060micro controller and AD5363DA converter. In VS2008development platform, the thesis finished the work control software design. The system provides a friendly user interface and achieves tamper work automatic control.After the system functional test, the tamper automatic control system designed in this thesis achieved the desired design goals that the tamper automatic work control is realized which improves the efficiency and accuracy of tamping operation with a good prospects.
