JP6154655B2 - Passenger guidance system using on-board information - Google Patents

Description

  The present invention relates to a passenger guidance system in a station using on-board information of a train regarding notification of approach of a train to a user who waits for arrival of a train at a platform of the station.

A conventional passenger guidance system that recognizes the presence of a train and guides the approach of the train is information on train detection when the train short-circuits the track circuit, and information from the train detection device disclosed in Patent Documents 1 and 2. The information from the fixed train detection position was used.
In addition, since the time from the train detection position to the station differs depending on the type of train, in addition to the train detection device disclosed in Patent Document 3, the difference in time until the train arrives using the train type information There is a known method for guiding train approach in consideration.

  However, even if the type of train is taken into consideration at the fixed train detection position, the train moving speed is not always constant, so there is more time than necessary from the end of the train approach guidance until the train enters the platform. There is a problem that the user recognizes that the train has suddenly entered due to the occurrence of the time interval.

  The present invention is based on the time it takes to reach the station calculated from the position information of the train, the moving speed, the braking ability, the travel route and the position of the station, and the information on the destination and type of the train. By using the time required for the train approach guidance at the calculated station, the onboard device notifies the start of the approach guidance to the passenger guidance device at the station, until the train enters the platform from the end of the train approach guidance Provides a function that keeps time constant.

  By adding information on the destination and type required for the guidance of the train at the station to the information notifying the start of the approach guidance to the passenger guidance device of the station, the passenger guidance device of the station makes the destination and type of the train It is unnecessary to have this information.

  The effect of the present invention is to make the time from the completion of the train approach guidance to the arrival of the train constant when the time until the train reaches the station and the time required for the train approach differ for each train. It becomes possible.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a passenger guidance system using on-vehicle information according to the present invention.

  The on-board device equipped on the train 100 side includes a calculation unit 110, an on-board information storage unit 120, a train position detection unit 130, and an on-board information transmission unit 140.

  The on-board information storage unit 120 stores the traveling ability of the train 100, information on the traveling track, position information on the station, and the like. The train position detection unit 130 detects the current position and speed of the train 100.

The calculation unit 110 calculates the time for notifying the station of approach guidance based on the information in the on-board information storage unit 120 and the train position detection unit 130, and sends the time to the on-board information transmission unit 140.
The on-board information transmission unit 140 sends the guidance notification 150 to the ground device 200 side by wireless communication or the like.

The ground device 200 equipped on the home side includes a calculation unit 210, a ground information storage unit 220, an on-vehicle information reception unit 230, and an approach guidance output unit 240.
The on-board information receiving unit 230 inputs the guidance notification 150 to the calculation unit 210. The ground information storage unit 220 stores information such as a destination of the train 100 and a vehicle-specific information necessary for the guidance of the train 100.

The calculation unit 210 generates approach guidance for the train 100 based on these pieces of information, and sends the approach guidance output unit 240 to the approach guidance output unit 240.
The approach guidance output unit 240 broadcasts a train approach guide to a user at the station platform using a speaker or the like.

FIG. 2 is a block diagram showing the processing of the calculation unit of the passenger guidance system using the on-board information of the present invention shown in FIG.
The calculation unit 110 of the train 100 includes an arrival time generation unit 112, a guidance time generation unit 114, and a guidance notification generation unit 116.

  The arrival time creation unit 112 receives the train movement speed and position information from the train position detection unit 130, and records the train braking capacity, the travel path, and the station position information recorded in the on-board information storage unit 120 to the station. Calculate the arrival time.

  The guide time creation unit 114 calculates the guide time of the own train by acquiring the guide time accompanying the destination and type information necessary for the guide of the own train recorded in the on-board information storage unit 120.

  The guidance notification generation unit 116 acquires the arrival time calculated by the arrival time creation unit 112 and the guidance time calculated by the guidance time creation unit 114, and generates a guidance notification 150 serving as a trigger for approach guidance on the ground device. It transmits to the ground apparatus 200 via the on-vehicle information transmission unit 140.

  The guidance notification 150 generated by the guidance notification generation unit 116 includes train identification information for identifying a train by the ground device 200.

  The calculation unit 210 of the ground device 200 includes an approach guidance output information creation unit 212. The approach guidance output information creation unit 212 uses the train identification information included in the guidance notification 150 received via the on-board information reception unit 230 to use the destination and type necessary for guidance of the train from the ground information storage unit 220. To generate approach guidance output information, and broadcast approach guidance via the approach guidance output unit 240.

  If information such as the destination of the train and the type of train is included in the guidance notification 150 transmitted from the on-board device, the ground device 200 does not use the information from the ground information storage unit 220. Train approach guidance can be performed.

  FIG. 3 is a flowchart illustrating a flow in which the on-board device calculation unit 110 notifies the ground device 200 of approach guidance by the train position detection unit 130 and the on-board information storage unit 120. In step S1, the guide time is calculated from the on-board information storage unit 120. Step S <b> 2 calculates the time until the train arrives from the train position detection unit 130 and the onboard information storage unit 120. Step S3 compares the calculated time to train arrival with the guidance time to determine the timing of the approach guidance notification. If the timing condition is not met, recalculation is performed. In step S4, an approach guidance notification is performed.

  FIG. 4 is a flowchart showing a flow in which the ground device computing unit 210 receives notification of approach guidance from the on-board device 100. In step S11, the presence / absence of notification of approach guidance from the on-board device 100 is checked. If there is no notification of approach guidance, the presence of notification of approach guidance is checked again. Step S12 creates approach guidance output information from the ground information storage unit 220.
