Definitions

  • the present invention relates to a train driving assistant system.
  • train driving assistant systems which can provide each train with a train running profile such that appropriate running profiles (specifically, momentary speed changes) of each train are calculated by using information of a traffic management system on a ground side which manages an operation of trains, and automatic driving according to the calculated running profile or manual driving based on the calculated profile can be performed, so as to perform highly optimized train driving while reducing burden of a driver during railroad vehicle driving.
  • JP-A-10-329718 or JP-A-2000-335419 proposes an example of such a train driving assistant system.
  • train onboard side system calculates a running profile because an onboard side system can grasp the most detailed motion characteristics of the formation.
  • information from ground side traffic management system is indispensable to calculate running profiles, as described in JP-A-10-329718 or JP-A-2000-335419 .
  • the onboard side devices have constraints of processing capability, it is difficult to construct a train driving assistant system which is closed with only an onboard side.
  • the invention aims to provide an appropriate train driving assistant system in which a difference of characteristics of information or a difference of processing capability is considered by optimizing disposition of running profile calculation processing units and division of roles.
  • a train driving assistant system includes a ground side system that includes a predicted timetable calculation processing unit which calculates a predicted timetable; and an onboard side system that includes a motor/brake control processing unit which transmits a motor/brake control signal, and a train position/speed acquisition processing unit which creates travel record data by acquiring a position and a speed of a train, in which a running profile calculation processing unit that calculates a running profile of the train on the basis of a predicted timetable is included in at least one of the ground side system and the onboard side system.

  • JP-A-10-329718 or JP-A-2000-335419 proposes an example of such a train driving assistant system.
  • JP-A-10-329718 describes that "a train travel guide device estimates motion characteristics of each train by using vehicle conditions such as tractive force and weight which are retained in a device as basic data" (refer to paragraph 0028).
  • JP-A-2000-335419 describes that vehicle data retained in a system is a fixed value (refer to Fig. 2 ). That is, it can be seen that the system described in the patent documents have a structure that calculates running profiles by using static data.

  • Information which is collected by onboard side devices of each train existing on the area under its jurisdiction can be collected from each formation through a network, but the amount or the frequency of information which can be transmitted to the ground side system is limited to some extent by a bandwidth of the network, propagation time, processing time at each device for mediateness, and the like.

As such, the margin time which is expected when the ground side system 100 calculates the running profile is reduced by reason detected by an onboard side.

That is, similar to a stop position of a station, the point x1 is a point where arrival target time is clearly defined, on the train driving assistant system.
  • the onboard side system 200 corrects the running profile according to its own determination, it is possible to realize an appropriate operation of trains that the ground side system 100 initially determines.
  • FIG. 10 An example for realizing this is illustrated in Fig. 10 .
  • the running profile is transmitted together with tabular data that is illustrated in Fig. 10 from the ground side system 100 to the onboard side system 200.
  • tabular data that is illustrated in Fig. 10 from the ground side system 100 to the onboard side system 200.
  • points where passing time and speed has to be kept are listed, and constraints regarding the passing time will be incorporated at a constraint setting step in the onboard running profile calculation processing.
  • the train driving assistant system may include a function of providing information for other personnel relating to a train operation, such as a conductor and a station staff.
  • a station staff of the station has to have passengers onboard prior to designated departure time.
  • a conductor of the train performs manipulation of door closing at the appropriate timing prior to the designated departure time, and has to secure safety of the train and platform.
  • a station staff or a conductor As information on the operation of a train obtained from a running profile calculated by train driving assistant system is delivered to a device that a station staff or a conductor can refer to, their tasks necessary for the train operation can be performed at appropriate timing.
  • An example of a device which a station staff or a conductor can refer to is a fixed terminal disposed at a station office room or a conductor room on a train, or a mobile type terminal that the station staff or the conductor carries.
  • Information on the train operation that the station staff or the conductor obtains also can be input from the device that the aforementioned station staff or conductor can refer to, and which can be reflected in the predicted timetable calculation processing or the running profile calculation processing of the train driving assistant system.
  • the train driving assistant system can more accurately grasp an operation situation of a train, and can calculate the running profile with high feasibility.
  • a station staff or a conductor who confirms a situation of the station or the train inputs expected delay time to the system.
  • the train driving assistant system corrects predicted timetable or running profile on the basis of the expected delay.
  • the correction of the running profile can be performed by any one of the ground side system 100 and the onboard side system 200.
  • information on the expected delay may be incorporated at a constraint setting step in the onboard running profile calculation processing.
  • information on the expected delay may be incorporated at the constraint setting step of the assumed running profile calculation or the modified running profile calculation.
  • Fig. 11 illustrates an example of a configuration of the train driving assistant system to which information from a conductor and a station staff can be input.
  • means for inputting information from the conductor and the station staff is added to Fig. 1 , but in the same manner, the means for inputting the information from the conductor and the station staff may be added to Figs. 2 through 4 .
  • a person who inputs information is not limited to the conductor and the station staff, and the information can also be incorporated from other persons relating to the train operation, such as maintenance workers, workers at a depot, or cleaning workers, by the same configuration.
  • the train driving assistant system can reflect the information in calculating the running profile at an appropriate step in accordance with a place where the information generates and management entity of the information, and thus, it can be said that this configuration is suitable for incorporating various information with different characteristics.
  • the train driving assistant system has characteristics that driving assistant will be available under a certain limit, even when a part of the system does not function.
  • driving assistant is still available by autonomous determination of the onboard side system 200 based on the information the onboard side system 200 received last from the ground side system 100.
  • Advisory information the onboard side system 200 provides remains appropriate, as long as there is no change of an operation situation such that a recalculation of the predicted timetable is needed.
