Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-train transfer guide device for providing time guidance of a transfer train at a next transfer station in a train.

[0002]

2. Description of the Related Art In large cities, trains run on multiple routes to accommodate the use of countless commuters, school attendants, and other ordinary passengers. It is often necessary to change trains on different routes at several stations. In such a case, the time at which the passenger arrives at the destination is significantly changed depending on whether the train is connected or not at the transfer station, which may cause inconvenience to passengers.

Therefore, conventionally, in order to allow passengers to easily know the time when they arrive at the destination they are going to, the departure time and the destination station are entered at the departure station, or the destination station and its arrival. A destination station arrival time calculation device has been developed which calculates and displays an arrival time at a destination station and a suitable departure time by inputting the time.

FIG. 6 shows a conventional example of such a destination station arrival time calculating device. In this device, the passengers at the station operate the keyboard 12 to input data such as the departure station, the destination station, and the departure time.
This data is accepted through and the chain information to the transfer station information corresponding to the departure station code and the destination station code is read from the chain information storage unit 13.

The transfer station information storage unit 14 stores information on which route, from which station to go up and down, to get to and from which station to go from the departure station to the destination station. Each station timetable storage unit 15 stores a timetable for each station (this is a timetable for up / down, weekdays / holidays), and based on the chain information to the transfer station information,
The transfer station information storage unit 14 supplies the transfer station code, and according to the transfer station code, each station timetable storage unit 15 selects and reads out the transferable train time at the corresponding transfer station, and performs main control via the bus 18. Give to part 11. Further, the required time information storage section 16 for each route stores the required time between stations for each route, and outputs the required time between stations on the bus 18 according to the code for each route.

Then, the main control unit 11 uses these pieces of information to calculate the time of arrival at the destination station, and the arrival time indicator 1
Display on 7.

In this way, the passenger can know the arrival time at the destination station from the display of the display 17 by inputting the departure station, the destination station and the departure time data from the keyboard 12.

[0008]

However, in such a conventional destination station arrival time calculating device, since it is necessary to perform an operation from a keyboard as information input, it is usually installed at a station information desk or the like. , It was not possible for many people to know the arrival time at each destination station at once.

[0009] In addition, especially at subway lines and stations where other companies cross lines, the platforms for transfer trains are often far away, and although passengers could change trains a little earlier, the transfer station I was often disappointed because I couldn't get on the train because I didn't know the time to get to the transfer line.

In trains and the like, the transfer connection guidance at the next stop station is broadcast in the car, but it is often overlooked only by audio broadcasting, and there is a problem that passengers cannot be provided with sufficient transfer change information. .

Furthermore, on routes with a short distance between stations and with a large number of trains, for example, each E-den line and each subway line, there is no time to perform in-house broadcasting until the transfer time guidance, and such guidance has not been given. .

The present invention has been made in view of the above conventional problems, and a large number of passengers can be displayed by displaying the time information of the transfer train at the nearest transfer station in the train and the transfer travel time. It is an object of the present invention to provide an in-train transfer guidance device capable of viewing the transfer guidance display at a time.

The present invention also provides an in-train change-over guide device capable of notifying passengers by displaying a change-over train that is in time if it moves in a hurry at a transfer station in a manner different from other displays. The purpose is to do.

According to a first aspect of the invention, there is provided a transfer line timetable storage for storing line name and timetable information for each transfer line at each transfer station of a route on which a train runs. Section, a transfer transfer time information storage section that stores transfer transfer time information for each transfer line at each transfer station, transfer information storage information that stores transfer line presence / absence information for each station on the route, and line name information for the transfer line Section, the required time information storage section that stores the required time information between each station of the route, and the fact that the train has departed from the station with the train A time required calculation unit that extracts the transfer station and calculates the time required to reach the next transfer station, and an estimated time calculation unit that calculates the estimated arrival time at the next transfer station from the time required to reach the next transfer station. Add the transfer travel time at the next transfer station to the estimated arrival time, and extract the appropriate number of time data of the train leaving the next transfer station after the added time as transferable train time data from the transfer line timetable storage However, it is provided with a transfer train search unit to be displayed on the in-vehicle display.

According to a second aspect of the present invention, in the in-train transfer guidance apparatus according to the first aspect, after the estimated arrival time at the next transfer station calculated by the estimated arrival time calculation unit, the transfer travel time at the relevant transfer station elapses. It is equipped with a warning display time data creation unit that retrieves time data of the transfer trains that depart up to and displays the corresponding time data on the in-vehicle display in a manner different from that of other transferable train time data. .

[0016]

According to the in-train transfer guidance device of the invention of claim 1,
When the train departs from a station, the travel time calculation unit searches for the next transfer station with the next transfer line connection based on the information in the transfer information storage unit, and also uses the information in the travel time information storage unit. Based on the required time to the next transfer station, the estimated arrival time calculation unit calculates the estimated arrival time at the next transfer station from the required time to the next transfer station calculated by the required time calculation unit.

Then, the transfer train search unit adds the transfer travel time at the corresponding next transfer station stored in the transfer transfer time information storage unit to the estimated arrival time at the next transfer station calculated by the estimated arrival time calculation unit. Then, an appropriate number of time data of the train leaving the next transfer station after the added time are extracted from the transfer line timetable storage unit as transferable train time data and displayed on the in-vehicle display.

If the train departs from a station in this way, the next transfer station at which the train can be transferred next and the transferable train time data for each transfer line at that transfer station are automatically extracted and displayed on the in-vehicle display. In this way, passengers are provided with transfer guidance information in a timely manner.

According to a second aspect of the present invention, in the in-train transfer guidance device according to the first aspect, after the estimated arrival time at the next transfer station calculated by the estimated arrival time calculation unit, the transfer travel time at the relevant transfer station elapses. By extracting the time data of the transfer train that departs up to and displaying the corresponding time data in a different way from the display of other transferable train time data on the in-vehicle display, if you move quickly at the next transfer station It also displays transfer train time data that may be transferred to further improve the service of providing information to passengers.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows a block diagram of a common embodiment of the in-train change-over guide device according to the first and second aspects of the invention. The in-train transfer guidance device of this embodiment includes a transfer line timetable storage unit 1, a transfer transfer time information storage unit 2, a transfer information storage unit 3, and a route-specific required time information storage unit 4 as storage units. ing.

The in-train transfer guidance device of this embodiment also includes a current position input device 5 for detecting the current position of the train, a main control device 6 for performing various arithmetic processes according to a program installed in advance, and a transfer guidance. The vehicle interior display 7 for displaying information is provided.

The transfer line timetable storage unit 1 stores timetable information for each transfer line at each transfer station of the route on which the train runs, and the transfer transfer time information storage unit 2 stores each transfer line for each transfer station. Stores transfer time information. The transfer information storage unit 3 also stores transfer line presence / absence information for each station on the route, and, if there is a transfer line, transfer information for chaining the timetable and transfer time information of the transfer line, and the required time for each route. The information storage unit 4 stores required time information between stations on the route.

The main controller 6 performs necessary arithmetic processing in accordance with a software program installed in advance. The main controller 6 is configured as follows according to its arithmetic function.

That is, when the current position input device 5 detects that the own train departs from a station, the transfer information storage unit 3
Next transfer station search unit 6a that searches for the next transfer station that has the next transfer line connection based on the information of The required time calculation unit 6b for calculating the required time to the transfer station, and the required time to the next transfer station calculated by the required time calculation unit 6b for the time when it is detected that the current location input device 5 has departed the station. Estimated arrival time calculator 6 that calculates the estimated arrival time at the next transfer station by adding
It has c.

The estimated transfer time at the next transfer station stored in the transfer transfer time information storage unit 2 is added to the estimated arrival time at the next transfer station calculated by the estimated transfer time calculation unit 6c, The train transfer time that leaves the next transfer station after the addition time is set as the transferable train time. After the scheduled arrival time, the time of the transfer train that departs until the transfer transfer time at the transfer station has elapsed is searched, and the applicable train time differs from the display of other transferable train times on the in-vehicle display 7. A warning display time data creation unit 6e for displaying in a mode is provided.

Next, the operation of the in-train transfer guidance device having the above configuration will be described. As shown in Fig. 2, the Ginza line is used as the route, and the train departs from Omotesando towards Shibuya. In such a state, the current position input device 5 recognizes the current position in conjunction with opening and closing the door and starting the train, and inputs the current position to the main control device 6 (step ST1 in the flowchart shown in FIG. 4).

The next transfer station search unit 6a of the main control device 6 searches the next transfer station from the transfer information storage unit 3 at the timing of departure from the station. In this transfer information, information obtained by chaining the line-by-line timetables for each transfer station in the transfer line timetable storage unit 1 and the transfer-line-specific travel time information in the transfer transfer time information storage unit 2 for each transfer station When it is set and it is recognized that the train departs from a certain station, the chains CH1 to CHN are searched by the transfer information at the corresponding station.

If the transfer chain is not found at the next station in this search, it means that there is no transfer line at the next station. In such a case, the transfer chain is transferred to the next station or the next station. Repeat the search until found. Along with this, the required time calculation unit 6b causes the next transfer station search unit 6a.
In parallel with the search of the transfer chain by, the required time between stations is sequentially added until the transfer chain is found by using the information in the route-based required time information storage unit 4. Figure 3
In the example above, we have just departed from Omotesando station, so we can find the transfer chain CH1 for the next transfer station, Shibuya station, at Omotesando station, and it is also found that the time required from Omotesando station to Shibuya station is 3 minutes. (Steps ST2 to ST5).

When the chain information of the next transfer station is found, the estimated arrival time calculation unit 6c adds the required time to the next transfer station calculated by the required time calculation unit 6b to the departure time of the final departure station. Calculate the estimated arrival time at the next transfer station. In the case of FIG. 3, it takes 3 minutes to Shibuya station which is the next transfer station, so when the departure time of Omotesando station is 20:52 minutes, the estimated arrival time of Shibuya station is 20:55 (step ST6).

When the transfer chain information and the estimated arrival time of the next transfer station are calculated in this manner, subsequently, the transfer train search unit 6d searches the transfer time information storage unit 2 to store the transfer information at the next transfer station. The transfer chain information set in the section 3 is searched, and a suitable number of time data of the trains departing each transfer line after the estimated arrival time are extracted, up to a maximum of 10 in this case. In the example of FIG.
The estimated time of arrival at Shibuya Station is 20:55, and after this time, the time data of the train departing the Toyoko Line, Inokashira Line, Yamanote Line, etc. is extracted (steps ST7, S).
T8).

Further, the warning display time data creation unit 6e searches the transfer chain information, and among the transferable train time data for each transfer line extracted by the transfer train search unit 6d, from the estimated arrival time to the estimated arrival time. Time data of trains that leave the relevant transfer station until the time when the travel time to the transfer line is added (that is, time data of trains that may leave during transfer after arriving at the transfer station) ) Is extracted, the in-vehicle indicator 7 is instructed to display a warning for the corresponding time data, and the normal display is instructed for the other time data. The difference in display mode between the normal display and the warning display can be achieved by, for example, changing the display color of the warning display from the normal display, blinking, reversing, or the like (steps ST9 to ST11).

Thus, as shown in FIG. 5, the in-vehicle indicator 7 installed in a place where many passengers in the train can easily see it.
Is the station name of the next transfer station if you leave the station with the train,
The routes that can be changed at that station and the departure times of trains that can be changed for each line are displayed and provided to passengers. Moreover, in the case of this embodiment, in consideration of the travel time at the transfer station, the departure time of the train that may be boarded if you move in a hurry is displayed in a manner different from the departure time of the normal train, so especially It will be possible to provide kind information to passengers in a hurry.

In the case of the invention of claim 1, the estimated arrival time and the travel time for each transfer line are added without displaying the time of the train departing during the travel time at the next transfer station as in the above embodiment. It is also possible to extract an appropriate number of time data of the trains leaving each transfer line after the specified time, for example, up to 10 and display them on the in-vehicle display.

That is, in the block diagram of FIG. 1, the warning display time data creation unit 6e in the main control unit 6 is not provided, and the transfer train search unit 6d indicates the travel time to each transfer line at the scheduled train arrival time at the next transfer station. The time of the train leaving each transfer line after the added time can be extracted and displayed on the in-vehicle display 7. In this case, in the example of FIG. 3, the estimated time of arrival at Shibuya Station is 20:55, and the travel time to each transfer line, for example, 2 minutes for the Toyoko Line is added to this time 20:55. Only the time data of trains departing after 57 are extracted, and if it is the Inokashira line, the travel time of 3 minutes is added 2
Only the time data of the train departing after 0:58 will be extracted and displayed.

[0035]

According to the first aspect of the present invention, when the train leaves a station, the next transfer station at which the train can be transferred next and the transferable train time for each transfer line at the transfer station are displayed on the in-vehicle display. Since it is automatically extracted and displayed,
It is possible to provide passengers with transfer guidance information in a timely manner, and it is possible to reliably provide transfer information to passengers who want to know the transfer information in order to display and present the transfer time information on the display. The service can be improved.

According to the invention of claim 2, in the in-train transfer guidance device of claim 1, the transfer train that departs after the arrival time at the next transfer station and before the transfer travel time at the transfer station elapses. The time data is searched and the corresponding time data is displayed on the in-vehicle display in a manner different from the display of other transferable train times, so if you move quickly at the next transfer station, you may be able to change trains. The time data of transit trains that may not be available can be presented in an easy-to-understand manner, and the information providing service can be further improved for passengers in a hurry.
