DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle position guidance device for providing a train or other passenger in a railway transportation system with a detailed guide on the current position of a train or the like.

[0002]

2. Description of the Related Art FIG. 6 is an external view of a guide display device for a stop station or the like according to a conventional example. 2. Description of the Related Art Conventionally, in railway transportation, a guide display device 200 of a stop station or the like for indicating the name of a station where a train stops next to passengers in the vehicle has been known. The guidance display device 200 is a vehicle position guidance device in which a display surface 210 made up of a large number of LEDs or liquid crystals arranged in a matrix is provided in the entrance door of each vehicle or the upper part of a communication passage of each vehicle with the display surface 210 facing the interior of the vehicle. . According to this, while the station name is updated each time the train arrives and departs from each station, the character display on the display surface 210 and the sound from the attached speaker 220 facilitate the operation guidance for unfamiliar passengers and the like. . For example, FIG. 6 shows that the train then stops at Tokyo Station.

[0003]

However, the guide display device for a stop station or the like according to the conventional example has the following problems. Even if this guide display device is used to provide detailed guidance to passengers about the current position where the train is traveling, it is only possible to roughly display the relative relationship with the next scheduled station. For example, just after departure from each station, the middle of both stations, and the three closest steps to the next station. For this reason, it was not possible to display in real time the current position between stations according to the actual operation status of the train that the passenger most wanted to know.

[0004] Further, when this guide display device is installed in a crowded train or the like and the operation guide is to be provided to all the passengers riding the train, the view is blocked by crowds from the seated passengers. In some cases, the display could not be seen or could not be moved to a position that was easy to see. In such a case, it is usually difficult to confirm the outside scenery from the train window, and there is a difficult problem that each passenger cannot sufficiently provide the convenience of operation guidance. Removal was an important issue.

A device 40 and an information terminal 50 carried by a passenger or the like in the train TR, and the passenger accesses the on-board device 30 or the station device 40 as needed by the respective information terminals 50,
This is a configuration in which guidance regarding the current position P of the train TR can be received.

[0012] Such a train TR may be a subway train or any other vehicle as long as it runs along a certain route. Hereinafter, a general ground railway train will be described as an example. The train TR constitutes a shared vehicle according to the present invention. The passengers and the like include general passengers such as passengers in the station building of each station ST. L indicates the traveling distance from each station.

The station name tag 20 is a signal transmitter of the tag identification number corresponding to the railroad line, and at a predetermined point where the station ST enters or exits the station ST yard, on a sleeper inside or outside the track T. Or it is fixed between two sleepers. Then, the tag identification number is formed into a predetermined radio signal by a built-in battery or an external commercial power supply, and transmitted to the train TR passing over the station name tag 20 to notify the train TR of the station name where the station name tag 20 is installed.

The tag detector 31 demodulates the radio signal from each station name tag 20, obtains its identification number,
An interrupt signal is generated with the reception. The moving direction detecting unit 32 identifies the moving direction (for example, the upward direction) of the train TR from the detection order of the plurality of station name tags 20, 20. In addition, the speed detecting unit 33 detects a traveling speed of the train TR by introducing a speed signal from the speed generator G.

The position determining section 34 introduces the identification number, the interruption signal, the moving direction, and the traveling speed, and calculates the traveling distance L from the elapsed time from when the interruption signal is generated and the traveling speed. Then, while searching the tag position database 35 by the identification number, the installation position of the corresponding station name tag 20 is obtained, and the current position P of the train TR is calculated based on the traveling distance L therefrom.

The program is stored. The guidance information is distributed from the in-vehicle output processing unit 36 to the units 37 to 39 via the in-vehicle LAN.
For this reason, the guidance display device 37 can provide an accurate current position P between the stations and the estimated scheduled arrival time based on this, in addition to the next stop station as in the related art.

The in-vehicle transmission section 38 organizes the current position P and the like into a distribution message and transmits it to each passenger information terminal 50 by radio or infrared signal together with a display program. The out-of-vehicle transmitting unit 39 organizes the current position P and the like into a transmission frame, and transmits the transmission frame to the station device 40 by a radio signal or the like when the vehicle enters the communication area of the station device 40 described above. This current position guidance device 30B
Thereby, the current position P of the train TR can also be guided to passengers who cannot see the guidance display device 37 in the vehicle and passengers at the station.

FIG. 3 is an external view of an example of the guidance display device shown in FIG. This guidance display device 37 has a built-in in-vehicle transmission unit 37a in a conventional device arranged at the upper part of the entrance door of each vehicle, the upper part of the passage to another vehicle, and the like, and the transmission part is directed to the inside of the vehicle on the display surface 37b. It is attached. This eliminates the need to separately provide the in-vehicle transmitter 37a and attach it to a wall or ceiling, so that the installation work and its maintenance are easy and the appearance is good. Reference numeral 37c denotes a speaker for audio.

FIG. 4 is a block diagram of a configuration example of the station device shown in FIG. The station device 40 has a station output processing unit 41 including a local area network (hereinafter, referred to as a local LAN), which is a communication network in the station premises, and a memory server for various kinds of guidance information. Further, a station receiving unit 42 having a radio or an infrared light receiving / emitting device, a guide display device 43 for a user provided at a key point in the station premises, and a premises transmitting unit 44 having another radio are connected to a local LAN. , And these are connected to the station output processing unit 41.

Another position information forming apparatus 130A has a train operation timer 132 for measuring the total operation time and the above-mentioned speed detection section 33 of the train TR. Connect together. The position determining unit 134 has an operation distance database 135 for the train TR. The train operation timer 132 starts measuring the total operation time as the train TR leaves the starting station.

In this case, the running speed of the train TR is detected by the speed detecting unit 33 every moment, and the running distance from the starting station is obtained while integrating the running speed according to the total running time. Based on the result, the running database 135 is referred to. Thus, the current position P of the train TR over the entire travel route is finely estimated.
For this reason, the current position P between stations can be determined without detecting the station name tag 20 each time, whereby predetermined position information can be formed and transmitted to the current position guidance device 30B. In addition, only the start of timing of the total operation time may be performed by the base point tag which is the station name tag of the first station.
