The Research Of The Running Mode On The TDJ Controllable Retarders System

TDJ computer controllable retarders system is a kind of the most popular one which is applied in the hump of the marshalling yards. Computer controllable system is applied in the marshalling yards all over the world, not only because it can do work with any radial of the wheel, but also it is almost not affected by any curve redial compared with traditional ones.The TDJ computer controllable retarders system is programmed by us, which from the system of the project; it contains the section of the hump, peed adjusting system, the height grade of the car. Applied the approaching way downsized the time defense between Hard and Easy cars. We applied the emulating technique and the theory of the faint controlling in the system, and the equipment used extensively because of the practical and Efficiency.Firstly, the article introduced the mainly research on the running mode of TDJ controllable retarder type, installation number, and the design index which use the new type high load controllable retarder and solenoid. Numbers of controllable retarder can be decided on actual condition of yard. Secondly, the system hardware function confirmation and frame can be designed.The system hardware frame use field decentralized control which can adapt itself to bad environment in marshalling yard. The system hardware function can conform to the requirements of the system holistic project design. The article introduced confirmation of system software frame and function which includes weight software and control software. The weight software calculates car’s weight and send to the control software. The control software select the over speed car and send out control command.The research and all the designs are applied on the mid and small humps to solve the problem and advance the work efficient. This system not only can advance the work efficient, but also avoid the destroyed of the cars or the goods. Actually, the system which is used in the marshalling yard gets good results.The system which acquired highly command by the CP LTD. was used in the automatically hump system of34tracks in Bensenville. Now, the developed system is equipped on the large power motor checking base of HARBIN RAILWAY ADMINISTRATION. The regards on the running of the system certify that the TDJ distributed computer controllable retarders system is popular on the marshalling yards no matter today oi tomorrow!.
