    The past three years has seen the main influx of microprocessor based equipment the vital traction control field. British Rail now have the classes 90, 91 and 319 locomotives/multiple units with processor driven thyristor DC drives and the second-generation push-pull equipment in service, and the three-phase drive under development with the class 60 about to enter service. The author examines the ... View full abstract»

    London Underground Limited (LUL) have lived with microprocessors in train-bourne equipment for over ten years. The earliest microprocessor based system gave cause for concern for two reasons: firstly they did not perform as well as originally expected and secondly they did not last as long as they should. The author describes the various advantages and drawbacks of each of the numerous microproces... View full abstract»

    For the small company designing microprocessor controlled equipment for use on rail traction vehicles, all of the constraints on design and manufacture which affect a larger company-meeting performance, reliability and environmental requirements-still apply. There are also additional restrictions imposed by the limited resources of a small company to withstand the potential financial effects of fa... View full abstract»

  • Living with complexity [in railway software engineering]

    Publication Year: 1990, Page(s):3/1 - 3/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (140 KB)

    In this paper, the author argues that there are no reasons why the railway industry should be different from other industries with respect to its attitude to software engineering. For some years (perhaps about five) almost every new large railway control project has been applying structured techniques, mainly because of earlier disasters with other software methods. The author shows that we are no... View full abstract»

    In 1985, Brush introduced the present 68000 microcomputer system. Originally, it consisted of a CPU card, an analogue and a digital card. As the applications grew a number of other peripheral cards were added, some with microprocessors of their own. The author describes the use of this system for rail traffic control, the applications of which now include almost all types of traction equipment inc... View full abstract»

    Microprocessor control of traction equipment has been around for over 10 years. The first systems used single 8 bit processors carrying out relatively simple tasks but over the years this has grown into multiprocessor systems providing many and various features. With the advent of Gate Turn Off (GTO) thyristor technology, the AC motor, the AC motor is now replacing the conventional DC motor and th... View full abstract»

  • Microprocessors in data communications [for rail traffic control applications]

    Publication Year: 1990, Page(s):6/1 - 6/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (228 KB)

    The author looks briefly at the advantages microprocessors can offer in a data communication system for rail traffic signalling applications and considers the problems associated with providing a reliable and cost effective design. He argues that the future holds many advances in data communication and microprocessor technology and will therefore provide many interesting and varied opportunities View full abstract»
