Description

  The present invention relates to a vehicle information display device, a vehicle information display program, and a vehicle information display program recording medium that are attached to, for example, a train or bus vehicle.

  Conventionally, in vehicles such as trains and buses, the display device attached to the outer surface of the vehicle body has “vehicle destination”, “train type (normal, semi-express, Express) "or" Vehicle type (free seat, reserved seat, green, non-smoking) ". By looking at such information at a stop (where the vehicle stops such as a station platform or a stop), the user can confirm "what vehicle should be boarded".

  Japanese Patent Laid-Open No. 2000-40184 is known as an invention related to such a display device. This conventional technique is intended to solve the problem that a user can sufficiently obtain necessary information from a display device of one vehicle in response to the problem that the amount of information that can be displayed on the display device of the vehicle is small. It is.

For this reason, in the above prior art, receiving means for receiving train guidance information (train name, destination, vehicle number, vehicle type) from the operation management device and character information representing the train guidance information are deflected in a two-dimensional direction. Projection means for projecting with an optical signal and display means for displaying train guidance information are provided, and train information is displayed in text on the screen of a stopped vehicle.
JP 2000-40184 (released on February 8, 2000)

  However, the above prior art does not assume a situation in which a train passenger sees a display device installed on the train body at a place other than a stop, that is, a station platform.

  For example, as illustrated in FIG. 28, information on “destination”, “train type”, and “vehicle type” of a train 1000 that is stopped at the station platform 1001 is very important for a user who is in the station platform 1001.

  However, if there is no station platform 1001 in front of which the train 1000 can be boarded, such information on the train 1000 is meaningless. For example, as shown in FIG. 29, after the train 1000 departs from the station platform 1001, it is impossible to get on the train 1000, so that the “destination”, “train type”, and “vehicle type” of the train 1000 are known. Is completely meaningless.

  Similarly, the user knows the “destination”, “train type”, and “vehicle type” of the train 1000 moving far away from the station platform 1001 (such as an intermediate point between adjacent station platforms). But it has no meaning at all.

  Further, as shown in FIG. 30, before the train 1000 arrives at the station platform 1001, the train 1000 can be boarded, but the “destination”, “train type”, and “vehicle type” of the train 1000 are possible. Such information does not make much sense for users outside the station platform 1001.

  As described above, in the prior art, the same information is always displayed on the display device installed in the train regardless of the state of the train. Therefore, the information displayed on the display device is not optimal for the user.

  The present invention has been made to solve the above-described problem, and is a vehicle information display device, a vehicle information display program, and a vehicle information display that can provide optimal information to a user according to the state of the vehicle. The purpose is to provide a program recording medium.

(Point of invention)
The main points of the invention for solving the above-mentioned problems can be summarized as follows.
-Based on the distance between the position of the stop and the position of the vehicle on which the vehicle information display device is attached, for example, "Is the train on which the vehicle information display device is attached before the arrival at the station platform?" , "Is the train on which the vehicle information display device is attached stopped at the station platform?" And "Is the train on which the vehicle information display device is attached after leaving the station platform?" To do. Then, according to each determined state, “an index for determining whether or not to ride the latest train departing in the same direction (for example, how many minutes the vehicle to which the vehicle information display device is attached starts or How many minutes later the vehicle heading to the same direction as the vehicle on which the vehicle information display device is installed will depart) ”“ Destination of the train on which the vehicle information display device is installed ”“ Next train departing in the same direction ” "Information". If the vehicle is in any other state (traveling far away from the stop), “the time taken to arrive at the next station and information on the next station” is displayed. However, since it is difficult to directly measure the distance between the position of the stop and the position of the vehicle, in the embodiment, the state of the distance is indirectly determined based on time or speed. The correspondence between the configuration of the present invention and the actions and effects will be described in detail below.

  The vehicle information display device of the present invention is a vehicle information display device provided in a vehicle that moves between a plurality of stops, provided on the outer surface of the vehicle and displaying display data that has been input, Vehicle state determination means for determining whether the vehicle is stopped or traveling at a stop, display data corresponding to each state of the vehicle is created, and the determination result of the vehicle state determination means And display data generation means for outputting corresponding display data to the display means.

  According to the above configuration, the vehicle state determination means determines whether the vehicle is in a stopped state or a traveling state at a stop, for example, a station platform, and the display data generating means is Display data corresponding to each state is created, and corresponding display data is output to the display unit according to the determination result of the vehicle state determination unit. Therefore, the display means provided on the outer surface of the vehicle displays display data corresponding to the state of the vehicle such as when it is stopped or running at the stop. Thereby, the information display apparatus for vehicles of the present invention can provide the optimum information for the vehicle user.

  The vehicle information display device includes a storage unit that stores an operation schedule of the vehicle, and the vehicle state determination unit determines the state of the vehicle based on an operation time indicated by the operation schedule and a current time. It is good also as a structure.

  According to said structure, a vehicle state determination means is the said state of a vehicle based on the operation time which the operation schedule of a vehicle shows, and the present time, ie, the state where the vehicle is a stop state or a state where it is driving | running | working Therefore, the vehicle state can be determined with a simple configuration.

  The vehicle information display device includes a storage unit that stores an operation schedule of the vehicle, and the vehicle state determination unit determines when the vehicle heads for the second stop after arriving at the first stop. The traveling state is a state before the vehicle arrives at the first stop, and the display data creation means is a state before the vehicle arrives at the first stop by the vehicle state determination means. If it is determined that, based on the information stored in the storage means, display data including information on the departure time from at least the first stop of the vehicle is created and output to the display means Also good.

  According to said structure, in the state before a vehicle arrives at a stop, the operation schedule information from which the said vehicle leaves the 1st stop is displayed on the display means provided in the outer surface of the said vehicle. Thereby, for example, it is possible to provide effective information to passengers waiting for the arrival of the train at the station platform and passengers of the train traveling near the railway track and heading to the station.

  In the vehicle information display device, the information related to the departure time of the vehicle from the first stop may include a time from the current time to the departure time of the first stop of the vehicle. .

  According to the above configuration, the information about the departure time of the vehicle from the first stop includes the time from the current time to the departure time of the first stop of the vehicle. Users who are outside of the station said, “That train has a long stop time, so I can have breakfast outside the station.” “If there is a train that departs in the same direction after XX minutes, you can go outside of the station. You can make use of your free time, such as “I'm gonna drink,” or you can rush to the station platform, thinking, “If you do n’t get on this train, you have to wait for a long time.”

  The vehicle information display device includes storage means for storing an operation schedule of the vehicle and an operation schedule of another vehicle that operates in the same direction as the vehicle, and the second information after the vehicle arrives at the first stop. The traveling state determined by the vehicle state determination means when heading to the stop is a state before the vehicle arrives at the first stop or a state after the vehicle departs from the first stop, The display data creation means, when the vehicle state determination means determines that the vehicle is in a state before arriving at the first stop or a state after the vehicle has departed from the first stop, Based on the information stored in the storage means, display data including information on the departure time from at least the first stop of the vehicle that departs next to the vehicle heading in the same direction as the vehicle is created, and the display means In It may be configured to force.

  According to the above configuration, in the state before the vehicle arrives at the stop or the state after the vehicle departs from the first stop, the vehicle departs from the first stop that goes in the same direction as the vehicle. The operation schedule information of the vehicle to be displayed is displayed on the display means provided on the outer surface of the vehicle. Thereby, effective information regarding vehicles other than the said vehicle can also be provided to the user of a vehicle.

  In the vehicle information display device, the information related to the departure time from the first stop may include a time from the current time to the departure time of the first stop of the next vehicle.

  According to the above configuration, the display data relating to the next vehicle includes the time from the current time to the departure time of the first stop of the next vehicle. If you can get up to XX minutes, you can use your free time effectively.

  In the vehicle information display device, the display data creation unit may be configured to change a font size of text information displayed on the display unit according to a moving speed of the vehicle.

  According to said structure, if the moving speed of a vehicle increases, the font size of the text information currently displayed on the display means can be expanded, for example along the moving direction of the vehicle. Therefore, even when the vehicle is moving, the user can easily see the information displayed on the display means.

  In the vehicle information display device, the display data creating means moves the text information displayed on the display means in a direction opposite to the moving direction of the vehicle, and sets the moving speed of the moving vehicle. It is good also as a structure changed according to speed.

  According to the above configuration, the text information displayed on the display means can be moved in the direction opposite to the direction in which the vehicle moves, and the moving speed of the text information can be increased if the moving speed of the vehicle increases. . Therefore, even when the vehicle is moving, the user can easily see the information displayed on the display means.

  The vehicle information display device according to the present invention includes a display unit, a vehicle state determination unit that determines whether the vehicle is in a stopped state or a traveling state, and the vehicle state according to each of the above states. In addition to creating display data, display data creating means for outputting corresponding display data to the display means according to the determination result of the vehicle state determination means is provided.

  Therefore, the display means provided on the outer surface of the vehicle displays display data corresponding to the state of the vehicle such as when it is stopped or running at the stop. As a result, it is possible to provide optimal information for the vehicle user.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In order to facilitate understanding, an embodiment in which the present invention is applied to a train will be mainly described.

[Appearance of train in this example]
FIG. 2 is an external view (image diagram) of a train 1000 provided with the vehicle information display device 1 (1-1, 1-2) of the present invention. Below, the train 1000 demonstrates as what is provided with the information display apparatus 1 for vehicles. In FIG. 2, the train 1000 has a two-car train, but the present invention is not limited to this.

  These vehicle information display devices 1 display information appropriate for the user according to the status of the train 1000, that is, the positional relationship between the train 1000 and the station platform 1001.

  For example, as shown in FIG. 29, after the train 1000 departs from the station platform 1001, the destination of the train 1000 that has already departed is meaningless for the user, and information on the next train 1000 that departs from the station platform 1001 is useful. become. Therefore, in the situation as shown in FIG. 29, the vehicle information display device 1 should display information on the train 1000 that departs next from the station platform 1001.

  Further, as shown in FIG. 30, before the train 1000 arrives at the station platform 1001, the user who is outside the station platform may ask “when the train 1000 departs from the station platform 1001” or “the same direction as the train 1000”. Information indicating “an index for determining whether or not to get on a train toward a certain direction” such as “when the train going to the station departs from the station platform 1001” is useful. Therefore, in the situation as shown in FIG. 30, the vehicle information display device 1 displays information indicating an index for determining whether or not to take a train heading in a predetermined direction (“when the train 1000 departs from the station platform 1001” or “ "When the train going in the same direction as the train 1000 leaves the station platform 1001") should be displayed.

  Also, if the train is moving far away from the station platform, for example, near the middle point of adjacent stations, the time required to arrive at the next station and the next station information (station name, etc.) "Is displayed.

  In FIG. 2, one vehicle information display device is installed in one vehicle. However, the present invention is not limited to this. Any number of vehicle information display devices may be installed in one vehicle. Also good. Moreover, you may provide the display apparatus of one information display apparatus for vehicles with respect to a some vehicle.

[Hardware configuration]
A hardware configuration in the embodiment of the vehicle information display device 1 of the present invention will be described with reference to FIG. 3 includes a control device 10, a display device 11 (11-1 to 11-n, n is an arbitrary integer), a storage device 12, a speed measurement device 13, a clock device 14, and an input device 15. Each part is connected by a bus 16.

  The control device 10 is configured by a preprocessor, a memory, and the like, and operates according to a control program stored in the storage device 12, for example. More specifically, the result of processing by a functional unit described later is stored in the storage device 12 and data stored in the storage device 12 (hereinafter abbreviated as data in the storage device 12) is output to the display device 11. .

  The display device 11 (11-1 to 11-n) is configured by a light-emitting diode (LED), a liquid crystal display (LCD), or the like, and displays display data of the storage device 12. Of course, the vehicle information display device 1 does not need to include a plurality of display devices 11, and may include only one. Further, these display devices 11 may not be installed in one vehicle, but may be installed over a plurality of vehicles.

  The storage device 12 includes a RAM or a ROM, and has a work area for storing temporary data, processing data, and information (train type and the like) of the train 1000 on which the vehicle information display device is mounted.

  In addition, the storage device 12 has a departure time (corresponding to 50 in FIG. 4 to be described later) of each stop station on the operation route of the train 1000 on which the vehicle information display device 1 is mounted, and other trains that depart from the station. Information (corresponding to 51 in FIG. 4 described later) is stored. FIG. 4A shows an example of stored data when the route is as shown in FIG. As the departure time item 50 in FIG. 4A, time data is stored such that the train on the line XX leaves the A station at 10:20 and the B station at 10:40. Further, as an item 51 of information on other trains in FIG. 4A, data indicating that an express train departs at 10:18 and an ordinary train at 10:30 is stored at station A. In this example, the train information stored in the item 51 of other train information is limited to only train information that departs near the departure time of each station and goes to the same direction. In addition to the departure time, the arrival time may be stored.

  The speed measuring device 13 includes a speed sensor and measures the current speed of the train 1000. The clock device 14 measures the current date / time.

  Note that the speed measurement device 13 and the clock device 14 do not need to be directly connected to other devices via the bus 15, and may transmit and receive data via wireless, for example.

  The input device 15 is constituted by a keyboard or the like, and the conductor inputs various data such as the traveling direction of the train.

[Functional configuration based on block diagram]
Here, the functional configuration of the vehicle information display device 1 according to the present embodiment will be described with reference to the block diagram of FIG. The vehicle information display device 1 includes a storage device 12 as a storage unit, a display device 11 (display unit) as a display unit, a vehicle position state determination unit 100 (vehicle state determination unit), and a display data creation unit 103 (display). Data preparation means).

  The vehicle position state determination unit 100 and the display data creation unit 103 are configured by the control unit 10 and a program executed by the control unit 10.

  The vehicle position state determination unit 100 determines the position of the station platform and the train 1000 to which the vehicle information display device 1 is attached based on the departure time and the current time at each station stored in the storage device 12, for example. Determine the positional relationship. Specifically, whether the train 1000 is in a state before it arrives at the station platform, the train 1000 is in a stopped state at the station platform, the train 1000 is in a state after leaving the station platform, or the other state. Is determined. This process plays a role of switching display data to be displayed on the display device 11. This process will be described in detail later.

  The display data creation unit 103 includes a first display data creation unit 104, a second display data creation unit 105, a third display data creation unit 106, a fourth display data creation unit 107, a character size determination unit 101, A character movement control unit 102 is included. Then, the display data creation unit 103 creates display data to be displayed on the display device 11 according to the determination result of the vehicle position state determination unit 100.

  When the vehicle position state determination unit 100 determines that “the train 1000 is in a state before arrival at the station platform”, the first display data generation unit 104 generates display data corresponding to the state. When the vehicle position state determination unit 100 determines that the “train 1000 is stopped at the station platform”, the second display data generation unit 105 generates display data corresponding to the state. When the vehicle position state determination unit 100 determines that “the train 1000 is in a state after leaving the station platform”, the third display data generation unit 106 generates display data corresponding to the state. When the vehicle position state determination unit 100 determines that the state is other than the above (a place far away from the station platform), the fourth display data generation unit 106 generates display data corresponding to the state. . A detailed description of these processes will be described later.

  The character size determination unit 101 determines the character size to be displayed on the display device 11. However, in the vehicle information display device 1 according to the present embodiment, as shown in FIG. 5, the vertical direction of the font is kept the same length, and only the horizontal direction of the font (the moving direction of the train) is enlarged or reduced (801 is Example of expanding 800). The characters may be enlarged / reduced at the same aspect ratio, but in order to cope with the enlargement in the vertical direction, a display device that is long in the vertical direction is required.

  The character moving speed control unit 102 moves the character string displayed on the display device 11, and further controls the moving speed. FIG. 6 shows an example when the character movement speed control unit 102 moves the character string 807 leftward (806 is a display example after movement, and 805 is a display example before movement).

  Here, the effect of moving the character string will be described with reference to FIG. When the train 1000 moves in the right direction, the character string displayed on the vehicle information display device 1 seems to move in the same direction as the train 1000 for the stationary observer 810. Therefore, since the character string is moving for the observer 810, it is difficult to see the contents of the character string. However, if the character string is moved in the direction opposite to the moving direction of the train, the character string displayed on the vehicle information display device 1 appears to the observer 810 to stop, and the character string is kept stationary. It becomes easy to see. The character strings appear relatively stationary when viewed from the observer only when the train speed and the character string speed are exactly the same, but even if they are not the same, an effect close to that can be obtained. Thus, the character moving speed control unit 102 controls the moving speed of the character string in the direction opposite to the traveling direction of the train 1000 according to the traveling speed of the train.

[Explanation of operation by flowchart]
(Overview of operation)
Here, the outline | summary of operation | movement of the information display apparatus 1 for vehicles in this Embodiment is demonstrated using the flowchart of FIG.

  In S1, the vehicle position state determination unit 100 determines whether or not the train 1000 is in a state before arrival at the station platform (FIG. 30). Here, the determination process will be specifically described. First, the departure time of the station that arrives next is searched from the departure times (departure times 50 in FIG. 4) of the respective stations stored in the storage device 12. Then, when the current time satisfies the condition of “Time Relevant by Search-T1 <Current Time <Time Relevant by Search-T2”, it is determined that the state is “the state before the train 1000 arrives at the station platform”. However, T1 and T2 are arbitrary constants determined in advance. For example, T1 = 2 minutes and T2 = 1 minutes may be used. This method is not a method for directly determining the position state of the train 1000 based on the position of the vehicle with respect to the position of the station platform (stop), but as a result, it can be said that the method is indirectly realized. .

  If it is determined in S1 that the train 1000 is in a state before arrival at the station platform, the process proceeds to S5. The process of the first display mode in S5 will be described in detail later.

  In S2, the vehicle position state determination unit 100 determines whether or not the train 1000 is stopped at the station platform. Here, the determination process will be specifically described. First, the departure time of the currently stopped station is searched from the departure time (departure time 50 in FIG. 4) of each stop station stored in the storage device 12. Then, if the condition “time corresponding to the search−T2 <current time <time corresponding to the search + T3” is satisfied, it is determined that “the train 1000 is stopped at the station platform”. However, T2 and T3 are arbitrary constants determined in advance. For example, T2 = 1 minute and T3 = 1 minute.

  If it is determined in S2 that the train 1000 is stopped at the station platform, the process proceeds to S6. The processing in the second display mode in S6 will be described in detail later.

  In S3, the vehicle position state determination unit 100 determines whether or not the train 1000 is in a state after leaving the station platform (FIG. 29). Here, the determination process will be specifically described. First, the departure time of the station that has been stopped so far is searched from the departure times (departure time 50 in FIG. 4) of each stop station stored in the storage device 12. Then, if the condition of “corresponding time by search + T3 <current time <corresponding time by searching + T4” is satisfied, it is determined that the state is “the state after the train 1000 leaves the station platform”. However, T3 and T4 are arbitrary constants determined in advance. For example, T3 = 1 minute and T4 = 2 minutes may be used.

  If it is determined in S3 that the train 1000 has left the station platform, the process proceeds to S7. The processing in the third display mode in S7 will be described in detail later.

  In S4, it is determined whether or not the operation of the train 1000 is completed (operation end).

  The fourth display mode at S8 is in any state of S1 to S3, that is, the state where the train 1000 is moving at a substantially constant speed in a place away from the station (for example, near the middle point of the adjacent station). Display mode. The process of the fourth display mode in S8 will be described in detail later.

In the above description, the positional relationship between the station platform 1001 and the train 1000 is determined based on the time, but may be determined based on the train speed and the increase / decrease in the train speed. For example, in S1, if the vehicle is decelerating and 0 km / hour <current speed <50 km / hour, it is determined that the train 1000 has not yet arrived at the station platform. In S2, if “current speed == 0 km / hour”, it is determined that the train 1000 is stopped at the station platform. In S3, if “accelerating and 0 km / hour <current speed <50 km / hour”, it is determined that the train 1000 has left the station platform. Further, the vehicle position state determination method may employ a known technique using a position sensor, GPS, or the like in addition to the above-described one.
Further, as described above, it is not necessary to perform all the determination processes of S1 to S3, and the display mode may be switched by determining only a part of the states as shown in FIGS.

(First display mode)
Here, the first display mode in the process of S5 of FIG. 8 will be described in detail using the flowchart of FIG.

  In S <b> 101, the first display data creation unit 104 creates text information to be displayed on the display device 11. Here, the process of S101 will be specifically described. First, for example, the departure time of station A about to arrive at train 1000 (departure time 50 in FIG. 4) is acquired from storage device 12, and “index for determining whether to ride on train 1000” (from train A's station A) 1st text information which shows the information regarding the departure time of No.) is produced. In addition, the station A departs at the time closest to the departure time, and information on other trains heading to the same direction as the train 1000 is obtained. 2nd text information which shows "(information regarding the departure time from A station of the other train which goes to the same direction as the train 1000) is produced.

  FIG. 13 is an example of text information created in S101. FIG. 13A is an example of first text information, and FIG. 13B is an example of second text information. 13A (shown as “?”) Displays a time calculated from “the departure time of the train 1000—the current time”. Similarly, in the portion 153 (shown as “?”) In FIG. 13B, the time calculated from “the departure time of the next train departing in the same direction—the current time” is displayed. . Either one of (A) or (B) in FIG. 13 may be displayed on the display device, or both may be displayed. Instead of displaying the time difference with respect to the current time, an absolute departure time may be displayed, such as “10:20 This car leaves A station”.

  In the state before the train 1000 arrives at the station platform (FIG. 30), information such as “destination”, “train type”, and “vehicle type” of the train 1000 is not very meaningful for users outside the station platform. No. This is because the user does not always get on the train 1000 before arrival at the station platform. Therefore, in this state, as shown in FIG. 13, information serving as an index for determining whether the vehicle can be ridden or whether the vehicle is stopped for a long time, and “index for determining whether to ride the train 1000” Alternatively, “an index for determining whether or not to take another train departing in the same direction as the train 1000” is displayed. As a result, when different trains, such as semi-express, normal, and express trains that go to the same direction, stop at one station at the same time and each depart in turn at different times, Since trains have a long stoppage time, I wonder if I can have breakfast outside the station. "If there is a train that departs in the same direction after XX minutes, I'd like to drink coffee outside the station." It is possible to use the time effectively, or to go to the station in a hurry, thinking that if you don't get on this train, you have to wait for a long time.

  In S <b> 102, the character size determination unit 101 determines the font size of the text to be displayed on the display device 11. Of course, as described above, only the horizontal direction of the font (the moving direction of the train 1000) is enlarged or reduced while maintaining the same length in the vertical direction of the font. At that time, the font size of the text is determined according to the train speed measured by the speed measuring device 13. However, the maximum font size is obtained when the train speed exceeds a certain threshold (for example, 50 km / hour), and the minimum font size is obtained when the train speed is 0.

  FIG. 14 is a diagram for explaining the relationship between the train speed and the font size of the text displayed on the display device 11. From FIG. 14, it can be seen that the font size is reduced to 160, 161, 162, and 163 as the speed of the train 1000 decreases. In FIG. 14, the font size has four levels, but the present invention is not limited to this.

  Thus, by changing the font size according to the train speed, even if the train 1000 is moving, the user can easily see the text contents of the vehicle information display device 1. In addition, when the train 1000 is stopped, it is displayed in a small font size, so that a large amount of information can be displayed on the display device 11, and as a result, the user can obtain a lot of information at one time. it can.

  FIG. 15 shows a display example when the vehicle information display device 1 is installed in a train 1000 and displayed with the font size enlarged. FIG. 15A shows a display example in which the train 1000 is stopped, that is, in a normal font size. FIGS. 15B and 15C are display examples in which the train speed is high. As shown in FIG. 15 (C), using a plurality of display devices 11 provided in the vehicle information display device 1, one unit of information (in the case of the figure, “the vehicle departs from A station after 3 minutes”). You may display. In this way, the upper limit value of the font size can be increased by using the plurality of display devices 11-1 to 11-n. Therefore, even if the train speed is high, the user can easily see the text content.

  FIG. 16 is a flowchart for explaining a process of displaying one unit of information on the plurality of display devices 11-1 to 11-n as shown in FIG. Here, the process will be described.

  In S1021, a basic font size (hereinafter referred to as a basic font size) is determined. The font size in S1021 is determined according to the above method, that is, the train speed.

  In S1022, the number of character strings that can be displayed on one display device 11 is calculated with the basic font size, and the character string to be displayed on each display device 11 is determined.

  In S1023, the font size of the character string displayed on each display device 11 is recalculated. The character string is displayed on each display device with the recalculated font size.

  In S103, the character moving speed control unit 102 determines the moving speed of the character string displayed on the display device 11. As described above, the character string is moved in the direction opposite to the traveling direction of the train. The moving speed of the character string is determined so as to increase as the speed of the train 1000 increases.

  FIG. 17 is an example showing the relationship between the moving speed of the train 1000 and the moving speed of the character string. In FIG. 17, the character string stops when the train is stopped, and the character string moving speed is increased in proportion to the train moving speed. When the train moving speed exceeds a certain threshold, the character string moving speed is constant. This is because if the character string speed becomes too fast, it is difficult for the user to see the contents of the character string. Such a situation can be avoided by limiting the maximum character string moving speed.

  Further, as shown in FIG. 18, in the display device 11, when the character string moves from one end (170) and reaches the other end (171), the display is not finished, but is repeatedly displayed from one end. (172) Form is desirable. FIG. 18 shows a state in which the character string moves from one end of the display device 11 to the other end (170, 171), and the portion disappearing from the other end is displayed again from one end (172). .

  In S104, the text information created in S101 is output to the display device 11 with the font size determined in S102. However, the character moving speed control unit 102 moves the text at the speed set in S103. Of course, when the clock of the control device 10 is low, it is possible to exclude the function unit that makes the font size and moving speed of the text variable.

  In S1, the vehicle position state determination unit 100 determines whether or not the train 1000 is in a state before arrival at the station platform, and if not (NO), the first display mode is terminated.

(Second display mode)
Here, the second display mode in the process of S6 of FIG. 8 will be described in detail using the flowchart of FIG.

  In S201, the second display data creation unit 105 creates text information to be displayed. The text content to be displayed may be the destination of the train 1000 or the train type. For example, text such as “express line XX” may be displayed.

  In S202, the text information created in S201 is output to the display device 11. The font size may be the one when the train speed is 0 (zero). Further, when the character string to be displayed is long and does not fit on one display device, the character string may be moved as described in the first display mode.

  In S2, the vehicle position state determination unit 100 determines whether or not the train 1000 is stopped at the station platform, and if not (NO), the second display mode is terminated.

(Third display mode)
Here, the third display mode in the process of S7 of FIG. 8 will be described in detail using the flowchart of FIG.

  In S301, the third display data creation unit 105 creates the text content to be displayed. Here, the process of S301 will be specifically described. Information on other trains that depart from the station after the current time (the next train that departs in the same direction as the train 1000) stored in the storage device 12 is acquired, and text indicating the information on the train is created. For example, in the case where data as shown in FIG. 4 is stored, assuming that the train 1000 has departed from the A station at 10:20, “A station 10: Acquire “30 normal” information and create text information.

  The text indicated by 350 in FIG. 21 is an example of the text created in S301. In a portion 351 (shown as “?”) In FIG. 21, a time calculated from “the departure time of the next train departing in the same direction—the current time” is displayed. If “the departure time of the next train departing in the same direction—the current time” is a negative number, the information is further switched to the information of the next train to leave.

  In a state after the train 1000 departs from the station platform (FIG. 29), information such as “destination”, “train type”, and “vehicle type” of the train 1000 has no meaning for the user. This is because the user cannot get on the departing train 1000. Therefore, if the next train information such as “which train will depart from the station” as shown in FIG. 21 is displayed, the user will be able to drink coffee outside the station if there is XX minutes until the next train. Free time can be used effectively, such as “I think it is already”.

  In S <b> 302, the character size determination unit 101 determines the font size of the text to be displayed on the display device 11. At this time, as described in the description of S102 in FIG. 13, the font size of the text is determined according to the train speed measured by the speed measuring device 13.

  In S303, the character moving speed control unit 102 determines the moving speed of the character string displayed on the display device 11. At this time, as described in the description of S103 in FIG. 13, the character string is moved in the direction opposite to the traveling direction of the train 1000. Similarly, the moving speed of the character string is determined so as to increase as the train speed increases.

  In S304, the text information created in S301 is output to the display device 11 with the font size determined in S302. However, the character moving speed control unit 102 moves the text at the speed set in S303. When the clock of the control device 10 is low, it is possible to exclude the function unit that makes the font size / moving speed of the text variable.

  In S3, the vehicle position state determination unit 100 determines whether or not the train 1000 is in a state after leaving the station platform, and if not (NO), the third display mode is terminated.

(4th display mode)
Here, the fourth display mode in the process of S8 of FIG. 8 will be described in detail using the flowchart of FIG.

  In S401, the fourth display data creation unit 107 creates the text content to be displayed. Here, the process of S401 will be specifically described. The time of arrival at the next station (the departure time of the next station may be substituted) stored in the storage device 12 by the control device 10 is acquired. Then, a text indicating “time required for arrival at the next station and information on the next station” is displayed.

  The text indicated by 450 in FIG. 23 is the text created in S401 when the train 1000 departs from the station A and is traveling near the intermediate point between the station A and the next station B, for example. This is an example. In the portion 451 (shown as “?”) In FIG. 22, the time taken to arrive at the next station calculated from “time to arrive at the next station—current time” is displayed.

  When the train 1000 is not already in the vicinity of the station platform and is running away from the station platform, the information such as the “destination”, “train type”, and “vehicle type” of the train 1000 is for the user. There is no meaning at all. This is because the user cannot get on the departing train 1000. If the user sees information such as “How long will it arrive at the next station” as shown in FIG. 23, “If it takes so much time to get to that station, it ’s a long walk, so take a taxi. You can guess the distance it takes to get to the station platform, such as “Let's go to the station”, and consider the means of transportation to go to the station platform.

  In S <b> 402, the character size determination unit 101 determines the font size of the text to be displayed on the display device 11. At this time, as described in the description of S102 in FIG. 13, the font size of the text is determined according to the train speed measured by the speed measuring device 13.

  In step S <b> 403, the character moving speed control unit 102 determines the moving speed of the character string displayed on the display device 11. At this time, as described in the description of S203 in FIG. 13, the character string is moved in the direction opposite to the traveling direction of the train. Similarly, the moving speed of the character string is determined so as to increase as the speed of the train 1000 increases.

  In S404, the text content created in S401 is output to the display device 11 with the font size determined in S402. However, the character moving speed control unit 102 moves the text at the speed set in S403. When the clock of the control device 10 is low, it is possible to exclude the function unit that makes the font size / moving speed of the text variable.

  In S1, the vehicle position state determination unit 100 determines whether or not the train 1000 is in a state before arrival at the station platform, and if it is determined that it is (YES), the fourth display mode is terminated. In the situation where the fourth display mode is executed, the train 1000 normally moves at a high speed. Therefore, even if the process of S402 or S403 is performed, the text may be very difficult for the user to see.

  Therefore, as shown in the flowchart of FIG. 24, a color to be displayed is determined based on the time taken for the fourth display data creation unit 107 to arrive at the next station (S401a), and the color is displayed on the display device 11. You may display. That is, the screen of the display device 11 is filled with a predetermined color.

  FIG. 25 is a diagram for explaining a process of changing the color of the screen of the display device 11 based on the time taken to arrive at the next station. FIG. 25 is an image diagram showing a situation where the train 1000 is heading to the X station 901 that is the next station to stop along the track 1004. In addition, in the sections indicated by 902, 903, and 904 in FIG. 25, the time taken to arrive at X station is 15 minutes or more, and the time taken to arrive at X station is 10 minutes. A section that is less than 15 minutes above, and a section that takes less than 10 minutes to arrive at X station. These sections can be determined from, for example, “the time of departure from the next station—the current time”. Then, the fourth display data creation unit 107 changes the colors displayed on the display device 11, such as red, yellow, and blue, according to the sections 902, 903, and 904.

  If the user outside the station platform knows the meaning of these colors, “If it takes so much time to get to that station, it ’s a long walk, so take a taxi and go to that station. You can guess the distance it takes to get to the station platform and examine the means of transportation to go to the station platform.

[Summary]
The main points of this embodiment will be briefly described below.
First, the vehicle position state determination unit 100 determines whether or not the train 1000 to which the vehicle information display device 1 is attached is in a state before arrival at the station platform. When it is determined that the train 1000 is in a state before arrival at the station platform, the first display data creation unit 104 determines whether or not to get on the latest train that departs in the same direction as shown in FIG. The text indicating “indicator” is displayed.

  In addition, the vehicle position state determination unit 100 determines whether or not the train 1000 is stopped at the station platform. Then, when it is determined that the train 1000 is stopped at the station platform, the second display data creation unit 105 displays information on the train 1000 (such as “train type and train”) such as “express line”. Destination).

  In addition, the vehicle position state determination unit 100 determines whether or not the train 1000 is in a state after leaving the station platform. When it is determined that the train 1000 is in a state after leaving the station platform, the third display data creation unit 105 shows “information on the next train leaving in the same direction” as shown in FIG. Display text.

  When the vehicle position state determination unit 100 determines that the vehicle is in any other state, the fourth display data creation unit 107 indicates “time required for arrival at the next station and information on the next station”. Display text.

  Thus, since the information presented according to each state of the train 1000 is dynamically created, it is possible to provide useful information to the user as described above.

  Moreover, since the font size and moving speed of the text displayed on the display device 11 are controlled according to the speed at which the train 1000 is moving, it is easy for the user to see the contents of the text.
