Definitions

  • This invention relates to a system for administration and control of train service.
  • Prior art train service administration and control systems which can attain unmanned train operation are broadly classified into a so-called centralized control type and a so-called decentralized control type.
  • a prior art system of the centralized control type is described by Yoshida et al. in the "Paper of the 17th Domestic Symposium on Utilisation of Cybernetics in Railroads", November 1980, pages 629-633, and is shown in FIG. 1.
  • an information transmission line 6 extending along the entire length of the track (not shown) laid for running of trains 7A to 7X (of which only two, 7A and 7X, are shown) is divided into a plurality of sections 6A, 6B, 6C, 6D, ..., 6K, 6L, 6M and 6N (some of which are not shown).
  • Transmitter and receiver units 5A, 5B. ..., 5M and 5N are respectively connected to the individual sections 6A, 6B, .., 6M and 6N of the information transmission line 6.
  • the transmitter and receiver units 5C to 5L corresponding to the sections 6C to 6L respectively are not shown to avoid confusion of illustration.
  • a single or a plurality of information transmission units 4 are connected to all of the transmitter and receiver units 5A, 5B, ..., 5M and 5N to transmit and receive information required for the control of the operation of the trains 7A to 7X existing within the extent of the sections 6A to 6N of the information transmission line 6.
  • a single information transmission unit 4 is shown.
  • a train service administration and control unit 1 Connected to the information transmission unit 4 is a train service administration and control unit 1 to exchanging information with the information transmission unit 4.
  • platform door control units 10A to 10Z controlling opening and closure of doors disposed at the platform of stations 8A to 8Z.
  • train detection unit 11 and an interlocking operation unit 12 Connected also to the train service administration and control unit 1 are a train detection unit 11 and an interlocking operation unit 12. Both of the train service administration and control unit 1 and the information transmission unit 4 are collectively installed in a central control center.
  • the train service administration and control unit 1 functions to prepare the train service schedule, administrate the group of the trains and control the operation of the individual trains.
  • this sytem has such an advantage that the operators can acquire all the information of the whole system and can readily intervene or interrupt in the control as required.
  • This sytem has such another advantage that the installation of the important parts of the system in the central control center facilitates maintenance of those parts.
  • the prior art system of the centralized control type has such a disadvantage that, in the event of occurrence of an accident, the load attributable to the accident is added to the normal load of the train service administration and control unit 1, and the response speed for processing is inevitably reduced due to the concentration of the loads to be processed.
  • the prior art system of the centralized control type has such another disadvantage that the expansion of the system to deal with an extension of the train track is difficult since the load to be processed by the unit 1 is generally proportional to the length of the track or the frequency of train service.
  • FIG. 2 A prior art train service administration and control system of the decentralized control type is described by Kuwabara et al. in the paper referred to above, pages 654-658 and 659 to to 663, and is shown in FIG. 2.
  • station control units 9A to 9Z are disposed for the individual stations 8A to 8Z respectively. All of these station control units 9A to 9Z are connected to the train service administration and control unit 1.
  • Connected to the station control units 9A to 9Z are the platform door control units 10A to 10Z, interlocking operation units 12A to 12Z and station information transmission lines 13A to 13Z respectively.
  • the train service administration and control 1 monitors generally the status of the individual trains 7A to 7X and applies to the station control units 9A to 9Z, the train control information for controlling the trains according to a predermined schedule of train service.
  • the station control units 9A to 9Z control the operation of the trains 7A to 7X according to a predetermined sequence and timing. While the trains 7A to 7X are running, the train service administration and control unit 1 monitors the status of the trains on the basis of information applied through the information transmission unit 4 and transmits the control command through the information transmission unit 4.
  • the system of the decentralized control type has such an advantage that the load processed by the train service administration and control 1 can be distributed to improve the response speed for processing.
  • the maintenance of the distributed units is not easy, and the necessity for providing two systems of the train information transmission line 6 and station information transmission lines 13, leads to an increase in the cost.
  • the function of the disabled one of the station control units 9A to 9Z cannot be substituted by the train service administration and control unit 1 disposed in the central control center and since the trouble cannot be dealt with by intervention from the central control center, an operator must be dispatched to the associated stations 8A to 8Z for which the station control units 9A to 9Z are provided respectively.
  • the prior art system of the distributed control type is therefore defective in that the unmanning of the stations cannot be realized in such an event.
  • the present invention provides a train service administration and control system as set forth in claim 1.
  • the system of the present invention differs from the known system in that the administration and control unit is divided into a single administration-processing unit and a plurality of control-processing units constituting a hierarchy structure, and the tasks of the processing for administration and the processing for control are respectively allocated to respective stages of the hierarchy thereby improving the response speed for processing.
  • the present invention differs also from the prior art system of the distributed control type in that all information is collected in a central control center for conveniences of the operators, and simplification of the structure of the system and improvement in the maintenance are further achieved.
  • FIGs. 1 and 2 are block diagrams illustrating the prior art train service administration and control systems.
  • FIG. 3 is a block diagram of a preferred embodiment of the present invention.
