Description

  The present invention relates to an integrated display system, method, and program, and, for example, a system and method for providing display means on a vehicle body such as a taxi or other vehicles, and displaying contents such as local advertisements on the display means. Can be applied to.

2. Description of the Related Art Conventionally, a vehicle advertisement is displayed while a business vehicle is running, using a telematics technology that applies a communication system applied to an automobile. In general, in such vehicle display systems, large-sized cars such as buses and trucks are advertised with large wrapping advertisements. In addition, advertisements that stand out by the movement of vehicles, and advertisements that are specific to railways are run. It has been broken. Further, there are cases where advertisements in the surrounding area including downtown areas are expected from taxi body advertisements, and various vehicle display systems have been proposed that display local advertisements along the road in a timely manner while a taxi is traveling. (For example, see Patent Documents 1 and 2).
JP 2002-251158 A (paragraph 0040, FIG. 2, etc.) JP 2002-288525 A (paragraph 0019, FIG. 9 etc.)

However, the conventional techniques as described above have the following problems.
(1) Compared with large vehicles, the taxi body cannot be expected to have a wide display surface, so the advertising effect that is more noticeable than large vehicles cannot be expected.
(2) Moreover, it does not reciprocate or circulate around a certain section like a route bus, and it travels comparatively widely various places in many downtowns according to a customer's request. However, when these local advertisements are displayed, their sizes and shapes are different, and it is extremely difficult to switch many of them in a timely manner.
(3) For example, when displaying information on the bar in Shinjuku in Shinjuku and information on the bar in Ikebukuro in Ikebukuro, the emphasis on local advertisements may differ, and there may be differences in appearance. The relatively small display panel could not be shared.
(4) In addition, when a taxi body is provided with a display and a so-called commercial image or video is displayed on this display, it is unusual at first, but it may soon get bored, depending on the idea. Therefore, there is a need for a medium capable of various expressions so that it can be devised so that it can stand out, and the expression method can be changed one after another.
In particular, if a taxi stops next to a taxi stand at a station and waits for a customer, or if you go to a taxi pool in the order in which you entered the taxi pool after stopping at a taxi pool set up close to the taxi stand, Since a plurality of taxis are exposed to the eyes of people passing through the station and the vicinity of the station, there has been a demand for a method that can be effectively used for advertisement.

  The present invention has been made in view of the above circumstances, so that contents having various sizes and shapes are conspicuous and timely on a display surface provided in a vehicle having a limited area. An object of the present invention is to provide an integrated display system, method, and program that can be displayed and that can effectively use a taxi that is waiting as a passenger in front of a station as a vehicle as an advertising medium.

In order to achieve the object, the integrated display system according to claim 1 is configured to display contents related to each other as an integrated display unit group when display units provided in a plurality of vehicles are close to each other. An integrated display system for displaying,
Content accumulation means for accumulating and storing contents to be displayed on the display means in association with each of a plurality of stopping spaces in a group close to each other for the vehicle;
Position detecting means for specifying a stop space where the vehicle stops when the vehicle stops in any of the plurality of stop spaces;
Content determination means for retrieving the content by searching the content storage means based on the stop space specified by the position detection means;
Content allocating means for displaying the content extracted by the content determining means on the display means of the vehicle.

In the first aspect of the present invention, the vehicle is provided with display means, and the content is displayed on the display means. Further, when a vehicle provided with the display means stops in a stop space of the vehicle, content corresponding to the stop space is searched from a plurality of contents stored and stored in advance in association with each stop space. Displayed on the display means of the vehicle that stops in the stop space.
Here, the vehicle is a taxi, and the stop space is a taxi stop space arranged in a row at a taxi stand of a station or a taxi stop space arranged in multiple rows in a taxi pool provided near the taxi stand. It can be.
In this case, for example, if a taxi is waiting for a customer in a plurality of stop spaces arranged in a row at a taxi stand, the display means provided in the taxi will display the taxi for each stop space. Among the stored contents, the contents corresponding to the stop space where the taxi stops are displayed.
The stop space basically indicates a fixed range for one vehicle to stop.

For example, if three stop spaces A, B, and C are arranged side by side and taxis A, B, and C stop in each stop space, they correspond to the stop spaces A, B, and C, respectively. The contents A, B, and C are displayed on the display means of the taxis A, B, and C, respectively.
At this time, if the contents A, B, and C are, for example, one still image or moving image divided into three parts before and after, the display of the three display means is performed using the display means of the three taxis A, B, and C. It is possible to display an image having a size that matches the screen.
Further, as contents A, B, and C, the content A is a product name and one product image, the content B is a product image and product specifications different from the product image, the content C is the desired retail price and release date of the product, etc. By doing so, it becomes possible to display a large number of items for one commodity using a plurality of display means.

  In addition, the information that is displayed each time the number of taxis that stop in the stop space increases, and the taxi stops in all the stop spaces, so that the entire information composed of multiple contents is completed Therefore, a person who looks at the content in front of the station for a relatively long time, such as at a meeting, can enjoy the taxi collecting in the stop space and completing information consisting of a plurality of contents.

Here, the vehicle is basically a taxi, but the present invention can be applied to any business vehicle that stops in a group in a place that is relatively easy to touch.
The vehicle is particularly preferably a commercial vehicle using a leased vehicle. If the vehicle is a leased vehicle, the present invention can be integrated with vehicles belonging to a plurality of companies without being limited to the company that uses the vehicle by leasing a vehicle provided with a display means or the like in advance.
Display means include, for example, liquid crystal display (LCD), plasma display panel (PDP) electroluminescence (EL) display, surface conduction electron emitter display (SED), LED display, fluorescent display tube (VFD), electronic paper, etc. Can be used.

The content is data such as text and images (still images and moving images), and is display data including, for example, character images for advertisement. In addition to the display means, the vehicle may be provided with a sound generation device (sound generation circuit, sound reproduction circuit, amplifier, speaker), and the content may include sound data.
In addition, the stop space is, for example, a stop space for a waiting taxi, but each stop space is a stop space for one vehicle.
The content storage means has a storage device for storing content, and functions as a database that stores the content in a searchable manner.
Further, the content storage means may be provided in each vehicle, or provided in a fixed station, so that the searched content can be output to the vehicle by data communication between the vehicle and the fixed station. Also good.
Further, when the content storage means is in the fixed station, the vehicle needs storage means for temporarily storing the content output from the fixed station.

The position detection means may be, for example, a GPS device, a device that measures a relative position (a device that measures each other's position using electromagnetic waves or the like), and a device that measures an absolute position (for example, A combination with a GPS device or an inertial navigation device) may also be used.
The position detection means is not necessarily mounted on the vehicle, and includes a device for recognizing the vehicle from structures such as satellites, airships, buildings, etc., thereby measuring the position of the vehicle (remote sensing). May be. In addition, when using GPS as the position detecting means, for example, a method (differential GPS or the like) that improves the measurement system by using an inertial navigation device or the like, or using the GPS device of each vehicle and the GPS of a fixed station, etc. It is necessary to improve the positioning accuracy.

Further, since the position detection means only needs to be able to detect which stop space of the plurality of stop spaces is located, a wireless tag (RFID) is attached to the vehicle or the stop space, and the wireless tag is attached to the stop space or the vehicle. A reading device may be provided.
Accordingly, when the vehicle approaches the stop space, the stop space ID for identifying the stop space is read by the reading device for the vehicle, or the vehicle ID for identifying the vehicle is read by the read device for the stop space.

Thereby, when there is a reading device on the vehicle side, it is possible to detect which stop space the vehicle has stopped by reading the stop space ID. Further, when there is a reading device on the stop space side, the stop space of the vehicle is notified by notifying the vehicle of the read vehicle ID that the vehicle ID of the vehicle has been read in the specific stop space. It is possible to detect whether the vehicle has stopped.
In addition, a wireless tag or a wireless tag reader is provided only in a reference stop space among a plurality of stop spaces in a group, and the relative position with respect to a vehicle parked in the reference stop space is measured. It may be possible to recognize in which stop space the vehicle is stopped.

  The content determination means is a computer system provided with a storage device as content storage means, and searches and extracts data in the content storage means. Therefore, the content determination unit is disposed at the same place as the content storage unit.

The content allocating unit stores the content retrieved and extracted by the content determining unit and outputs the content to the display unit. For example, the content allocating unit is mounted on each mobile body. Note that content allocation means may be provided in a fixed station as will be described later instead of a mobile unit to distribute the content, and a device for displaying the distributed content on the display unit may be arranged on the mobile unit side. That is, the content allocating means may be separately arranged on the mobile body side and the fixed station side.
In addition, in the integrated display system, a fixed station provided with content storage means is provided, data communication is performed between the fixed station and each vehicle, a stop space is determined, and content is based on the determined stop space. A configuration in which processing for searching is performed in a fixed station and content is distributed to the vehicle by data communication (centralized type) may be employed. In addition, without providing a fixed station, each vehicle is equipped with content storage means to determine which stop space each vehicle has stopped, and search and extract content corresponding to the stop space where each vehicle has stopped. However, it may be configured to display on its own display means (distributed type). In this case, the content data is distributed and stored in the storage device (storage means) serving as the content storage means of each vehicle so that the content data is shared among the vehicles in the integrated display system. Depending on the situation, the content may be transmitted and received between the vehicles.

The integrated display system according to claim 2 is the integrated display system according to claim 1,
The position detecting means constantly monitors a stop space where the vehicle is located, and when the stop space where the vehicle is located is changed and is located in any stop space, the vehicle is newly stopped. Identify the stop space,
The content determination means searches for and outputs the content from the content storage means based on the newly specified stop space,
The content allocating means replaces and displays the content on the display means in response to a change in the stop space due to the movement of the vehicle based on the content output from the content determining means. .

In the invention described in claim 2, when each vehicle moves, the content displayed on the vehicle display means when the vehicle is newly stopped in the stop space, moved between the stop spaces, or exits the stop space. Will be replaced.
For example, as described above, three stop spaces A, B, C are provided in this order, and taxis A, B, C as vehicles stop in this order in the stop spaces A, B, C, respectively. When the taxi A is present, the content A is displayed on the taxi A display means, the content B is displayed on the taxi B, and the content C is displayed on the taxi.

Here, when a customer gets on Taxi A, Taxi A leaves the group of stopping spaces. In this case, since there is no corresponding stop space in taxi A, for example, content may not be displayed on the display means of taxi A, but content that is not related to the stop space may be displayed.
At the taxi stand, the taxi A departs and the stop space A becomes vacant, but the taxi B that has stopped in the stop space B proceeds to the stop space A and parks in the stop space A. The taxi C that has stopped in the stop space C proceeds to the stop space B and parks in the stop space B. Thereby, the stop space C becomes vacant, and the taxi D can be newly stopped.

When the vehicle moves in this manner, the taxi B displays the content A corresponding to the stop space A, and the taxi C displays the content B corresponding to the stop space B. . When the taxi D is newly stopped in the stop space C, the content C is displayed on the taxi D.
And since then, the taxi will depart from the group of stopping spaces by leaving the first taxi with the passengers on board, and the remaining taxis in the stopping space will go to the front stopping space in order. The taxi that moves and vacates the stop space that is the rearmost in the direction of taxi travel, and a new taxi waiting for passengers stops in the vacant stop space.

By repeating the above-mentioned movement, the taxi is parked in the stop space from the outside and sequentially moves to the front stop space and leaves. Here, in the present invention, if a taxi provided with display means as a vehicle of the present invention is stopped in the stop space, the content A is displayed on the taxi stopped in the stop space A, and the taxi stopped in the stop space B The content B is displayed on the screen, and the content C is displayed on a taxi that has stopped in the stop space C.
That is, the taxi can perform content display in a state where the displayed content does not move even though the taxi sequentially moves and changes. In other words, the contents A, B, and C displayed on each taxi do not leave the current position even if the taxi moves to the front. It will appear that it is moving sequentially, and it is possible to produce a highly interesting performance.

  When there is a stop space where the vehicle is not stopped, the content corresponding to the stop space is not displayed. However, each taxi is basically packed in the front stop space according to the order of waiting for customers, so there will be no stop space where there are no taxis in the worm-eaten place, and the contents will be displayed in order It will be in the state.

  However, the taxi does not stop in the stop space on the rear side in the order of waiting for customers, and the content is not displayed. Therefore, when content is stored in the content storage means, the content is stored according to the number of vehicles stopped in a group of stopping spaces, and the number of vehicles stopped in the group of stopping spaces is measured. A number measuring unit may be provided, and the content determining unit may select the content based on the stop space where the vehicle has stopped and the number of vehicles currently stopped in the group of stop spaces. For example, when there are five stop spaces corresponding to five vehicles, different contents may be displayed from one case to five cases in a group of stop spaces.

In this case, the content to be displayed is changed by increasing or decreasing the number of vehicles parked in the stop space, and a display that is more interesting can be performed.
In addition, it is not necessary to change the contents for each vehicle that stops in a group of stopping spaces. For example, every five vehicles, every ten vehicles, etc. The content may be changed.

The invention according to claim 3 is the integrated display system according to claim 1 or 2,
The content storage means stores and stores a plurality of contents for each stop space,
The content allocating means is configured to be able to switch a plurality of contents with time and display them on the display means, and to switch and display the contents in synchronization with a display means of a vehicle parked in another nearby parking space. It is characterized by that.

In the invention described in claim 3, for example, the contents of each vehicle are switched over time with a plurality of vehicles stopped in a group of stopping spaces, and the contents are switched in synchronism with each vehicle. . As a result, content can be switched simultaneously (simultaneously) by a plurality of vehicles that stop in a group of stopping spaces, or the content can be switched in a wave shape with a predetermined time difference for each vehicle and for each row (vertical and horizontal or diagonal rows). Can do.
In addition, when synchronizing with a plurality of vehicles, if the content determination unit and the content allocation unit are mounted on each vehicle, a synchronization signal is output to each vehicle from a specific vehicle or a fixed station side, Based on this signal, each vehicle switches content at the same time as the output of the signal, or each vehicle switches content with a specific time difference based on the arrangement of the stop space where each vehicle stops. Can be taken.
In addition, when the content determination unit and the content allocation unit are in a fixed station, the content may be synchronized when the content is distributed to each vehicle.

The invention according to claim 4 is an integrated display method for displaying contents related to each other as an integrated display means group when display means provided in each of a plurality of vehicles are close to each other.
Accumulating and storing contents to be displayed on the display means in association with each of a plurality of stopping spaces in a group close to each other for the vehicle,
When the vehicle stops in any of the plurality of stop spaces, the stop space where the vehicle stops is specified,
Search the stored and stored content based on the specified stop space, extract the content,
The content extracted by the content determination means is displayed on the display means of the vehicle.

  The invention according to claim 4 has the same effect as the display integrated system according to claim 1. The configuration described in claim 2 or 3 may be added to the invention described in claim 4.

The invention according to claim 5 is a program for displaying contents related to each other as an integrated display means group when display means provided in each of a plurality of vehicles are close to each other.
Accumulating and storing content to be displayed on the display means in association with each of a plurality of stopping spaces in a group close to each other for the vehicle;
Identifying the stop space where the vehicle stops when the vehicle stops in any of the plurality of stop spaces;
Retrieving content stored and stored based on the identified stop space, and extracting content;
And outputting the extracted content to the display means of the vehicle.

  The invention according to claim 5 has the same effect as the display integrated system according to claim 1. Note that the configuration described in claim 2 or 3 may be added to the invention described in claim 5.

  According to the integrated display system, method, and program of the present invention, it is possible to construct a system that can display the entire contents by integrating the display means by the display means of the vehicles close to each other and search for appropriate contents. That is, it is possible to provide an integrated display system that can display content of various sizes and shapes in a timely manner and in a timely manner by using a display surface of a limited area of each of a plurality of display means. become able to.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining a schematic configuration example of a display integration system according to an embodiment of the present invention.
The integrated display system of this example is for displaying contents related to each other as an integrated display means group when display panels Dsp provided as display means provided in a plurality of vehicles are close to each other. It is. That is, the integrated display system is configured to display contents related to each other as an integrated display means group when display means provided in each of a plurality of vehicles are close to each other.

  Here, the present invention provides a display panel provided in a taxi in a taxi pool which is a parking space for a waiting taxi in a row of taxi stands in front of a station, or a parking space for a plurality of rows of waiting taxis near a taxi stand. Dsp is used for integrated display. In this example, the taxi is alone or close to a parking space for waiting for passengers, that is, a place other than a plurality of stopping spaces in a group. Content can be displayed in cooperation with multiple taxis.

  Here, before explaining the configuration related to the display of content in a group of multiple stop spaces, it is possible to display content in cooperation with a plurality of taxis alone or in close proximity to locations other than multiple stop spaces A simple configuration will be described.

  In this example, when the plurality of taxis (vehicles) Tx1, Tx2,... Connected to the same radio repeater TRx move in a discrete manner and repeatedly stop and start, each display panel Dsp. Are applied to each other to form an integrated display surface to display content such as advertisements. In addition, a content database 1 (content storage means) for advertising content and a narrow-area wireless local area network (wireless LAN: here, a wireless LAN dedicated to taxis is built using the existing wireless repeater TRx. A link analysis server (linkage analysis means) 2 connected to the content database 1 through data communication, and a frame allocation server 3 (content determination means, content allocation means). These database 1 and servers 2 and 3 are mounted on each taxi Tx1, Tx2,. Any taxi Tx1, Tx2,... Can function as a vehicle of this system by communicating with each other through the taxi. For data communication, a mobile phone or PHS communication line, taxi company wireless communication, or the like may be used instead of the wireless LAN. Note that the wireless LAN is connected to, for example, the Internet (INT), but may be connected to an extranet or an intranet operated by a taxi company, an advertising agency described later, or a vehicle leasing company.

Here, the content database 1, the linkage analysis server 2, and the frame allocation server 3 do not have to be separate devices, and may be configured by a single computer system. Text, images (still images, moving images) as content ) And the like (for example, a hard disk or a nonvolatile memory as a storage device) and a computer main body equipped with a CPU or the like. As will be described later, the content database 1, the linkage analysis server 2, and the frame allocation server 3 It is only necessary to be able to execute various programs that function as:
A taxi Tx1, Tx2,... As a vehicle in this example is a wireless communication device that enables data communication such as the content database 1, the linkage analysis server 2, the vehicle-mounted computer system that functions as the frame assignment server 3, and the wireless LAN described above. Is provided. Further, the wireless communication apparatus may have a plurality of directional antennas as described later and function as a relative position measuring unit for specifying a later-described arrangement pattern and relative position in the cooperation analysis server 2. Good.

FIG. 2 is a style diagram for specifically explaining the content database 1 shown in FIG.
The content database 1 shown in FIG. 2 includes image information (layout information) in which advertisement information (display information) groups 10, 10... Filed in association with 12. The description information 11 includes an advertisement ID (Adv0001 in this figure) that is an identification code that allows each advertisement information group 10 to be individually identified, and personal information (name of the billing destination of the advertisement fee) In the figure, it is a table including Name), contact information, etc.), area data indicating the display area (area information), and timer data indicating the display time zone (timer information).

  The image information 12 includes partial image information (Image001, Image002) 13a and 13b relating to each frame of the image information 12, and a position number (1) or (2) relating to the arrangement position of each frame (sub address 01 or 02 in this figure). The number of frames (2 in this figure, the number of mobile objects in the array pattern) and the arrangement (this book) In the figure, it is a table arranged together with data in a way of arrangement indicating that they are arranged in a horizontal row (front and back). In each subsequent process, the total number of frames becomes data for setting the number of taxis that can be displayed in an integrated manner, and the layout of the frames constitutes a cooperative relationship (array pattern) between taxis Tx1, Tx2,. It becomes data, and the pattern code becomes an identification code for specifying the cooperative relationship (array pattern) of the cooperative taxi group. The maximum value to which position numbers (1) and (2) can be added is the maximum number of frames that can be assigned to the advertisement image, and the maximum number (N in this figure) that can maintain the cooperative relationship. Note that either or both of such image information and partial image information may be in a compressed data format, for example, as a pixel value or a vector value.

Here, a frame is an image as a content displayed on each display panel Dsp when, for example, one display panel Dsp is provided in each taxi Tx1, Tx2,. Note that the image need not be a still image, and may be a moving image composed of a series of images.
Further, the number of display panels Dsp provided in the taxis Tx1, Tx2,... Is not limited to one, and may be plural. When there are a plurality of display panels Dsp provided in one taxi Tx1, Tx2,..., The same image may be displayed, or different images may be displayed. When different images are displayed, a plurality of images must be stored in the content database 1 as each frame. In this case, the partial image information described above includes a plurality of images corresponding to a plurality of display panels Dsp provided in one vehicle, and these images are included in one taxi Tx1, Tx2,. .. Stored in a state associated with the panel code corresponding to each display panel Dsp.

The positions of the display panels Dsp provided in the taxis Tx1, Tx2,... Are, for example, side surfaces (doors and front and back thereof) and upper surfaces (upper surfaces such as bonnets, roofs, trunks, etc.) The panel Dsp is formed so that it can be seen by a passerby or a passenger of another automobile, and the display panel Dsp provided on the upper surface is a building or a crosswalk (overpass) overlooking a road or a parking space for waiting for customers. ), Formed so as to be visually recognized from the platform of the station.
In addition, as the display panel Dsp formed on the side surface, for example, it may be formed on a window portion of a door.

Moreover, as a display panel, various flat panel displays, such as LCD, PDP, SED, ELD, VFD, and electronic paper, can be used, for example, As the display panel Dsp formed in a window as mentioned above, it is transparent. It is preferable to use a type LCD or a transflective (semi-transmissive / semi-reflective) LCD to ensure visibility from inside the taxis Tx1, Tx2,.

  Further, the content stored in the content database 1 is basically searched by the above-described pattern code and position number. When there are a plurality of display panels Dsp in one vehicle and each displays different contents, it is necessary to be able to search even with the panel code described above. As the pattern code, a different code is set for each preset arrangement pattern, and the arrangement pattern is determined by specifying the pattern code. In addition, the arrangement pattern includes a pattern in which the vehicle travels, that is, a pattern arranged in one row in the front-rear direction, a pattern arranged in two rows, a pattern arranged in three rows, a pattern arranged diagonally, or orthogonal to the direction of travel. A pattern arranged in the direction to be moved, a pattern arranged in a zigzag, and the like are set, and even in the same one row, two rows, etc., different patterns are set depending on the number of taxis Tx1, Tx2,.

The position number is set for each arrangement pattern. For example, in an arrangement pattern in which three taxis Tx1, Tx2,... Are arranged in a line in the front and rear, position numbers such as 01, 020, 03, etc. in order from the top. Will be assigned. That is, the position number indicates the relative position of each taxi Tx1, Tx2,.
Accordingly, by searching for partial image information by specifying a pattern code and a position number, it is possible to search for contents by specifying an array pattern and a relative position (position) within the array pattern. .

  Note that in the content database 1, at least for each advertisement ID, partial image information is stored for every preset arrangement pattern and for each relative position in each arrangement pattern, and when actually searching for content Requires an advertisement ID in addition to the above-described pattern code and position number. The advertisement ID basically corresponds to the advertiser on a one-to-one basis, but some advertisers may have a plurality of advertisement IDs in order to perform a plurality of different advertisements.

  Here, when the time is specified as the timer data of the description information including the advertisement ID, the advertisement ID is specified by the time by setting so that the time ranges of the timer data do not overlap for each advertisement ID. You may do it. Also, the time ranges indicated by the timer data may not overlap in each area data, and the advertisement ID may not overlap from the area data and the timer data. For example, even if two or more advertisement IDs are defined (Adv001, Adv002) for a time range (timer data) from 3:00 to 3:30, these advertisement IDs It is only necessary that the corresponding area codes are different. Thus, the advertisement ID can be specified from the area data and the timer data, and the partial image information can be searched from the pattern code and the position number.

In addition, when the timer data and the area data are specified, when a plurality of advertisement IDs are applicable, for example, a priority order and a time limit for each advertisement ID are provided, and an advertisement with a high priority order is provided. The ID is selected. In addition, when the content belonging to the selected advertisement ID is displayed, the display time is measured, and when the display time becomes the time limit, the advertisement ID having the next highest priority is selected. Also good.
Further, when searching the content database 1, all of the timer data, area data, advertisement ID, pattern code, and position number may be designated and searched.
In order to search the content database 1 by designating timer data and area data, a clock for designating time and a position measuring means for designating the absolute position of the vehicle as area data are mounted on the vehicle. Need to be. The watch function is mounted on the in-vehicle computer system, and the position measuring means is mounted with a GPS device used for specifying the array pattern and the relative position within the array pattern. If the GPS device is not mounted by using the relative position measuring means as will be described later in order to obtain the array pattern and the relative position in the array pattern, the area as the absolute position by the radio repeater TRx with which the vehicle communicates (Area) may be specified.
That is, at least one radio repeater TRx is provided for each area indicated by each area data, and when the vehicle moves from one area to another area, the radio repeater TRx to be communicated is switched. Thus, the area may be specified depending on which radio repeater TRx is communicating with.
From the above, the content database 1 displays the content to be displayed on the display means as an array pattern indicating the number of the groups of vehicles adjacent to each other and the arrangement of the groups of vehicles, and the relative positions of the vehicles in the array pattern. It functions as content storage means for storing and storing in association with.

  In addition, the above-mentioned arrangement pattern includes an arrangement pattern of a single vehicle in which no other vehicle exists in the vicinity of the vehicle, and content is stored in the content database 1 corresponding to the single arrangement pattern. Yes. Since there is only one taxi Tx1, Tx2,... In a single arrangement pattern, only one position number indicating a relative position is set independently. That is, a single position number is assigned to a single arrangement pattern corresponding to a single vehicle.

FIG. 3 is a schematic diagram for explaining a visual example of image information.
The image information 12 shown in FIG. 3 constitutes one advertisement image (in this figure (not shown for public order and morals violation)) by arranging the frames of the two partial image information 13a and 13b in a line in the front and rear direction. is doing. Accordingly, for these two frames, if the partial image information 13a, 13b is distributed to each display panel Dsp provided on the roof (roof) of the head taxi Tx1 and the subsequent taxi Tx2 that are linked to each other. , The advertisement image can be displayed in an integrated manner. Such image information is configured to have different sets of timer data for each set by setting a plurality of sets by changing the number of frames, shape and size of the same advertisement information, or by arranging a plurality of frames. Good. As a result, it is possible to change the way the image information is displayed and to improve the advertising effect.

In addition, the partial image information does not actually need to indicate a part of one image. However, for example, when the partial image information is arranged in the front-rear direction with respect to the traveling direction, the partial image information has a relationship corresponding to the front-rear relationship. It is preferable. Depending on the case, the same image data (characters may be images) may be assigned as each piece of partial image information, or image data having no positional relationship may be assigned as partial image information within the same arrangement pattern. It may be taken.
Further, the partial image information may be a moving image as described above, or may be composed of a plurality of series of image data whose order is designated in advance. For example, the partial image information is sequentially switched every 10 seconds or the like. It may be image data that is displayed. In the sequentially switched images, the order of the images may be meaningful (story-like) or random.

FIG. 4 is a style diagram for explaining a specific example of the cooperation analysis server shown in FIG.
As shown in FIG. 4, the data calculated and stored by the cooperative analysis server 2 collects coordinate information 21 regarding the current position of each taxi by communicating with a plurality of taxis through a narrow area wireless LAN. Based on the coordinate information 21, at least one linked taxi group Tx1, Tx2,... With which each taxi cooperates is extracted, and in this linked taxi group Tx1, Tx2,. It is obtained by organizing pattern information 22 related to the cooperative relationship and specifying each taxi Tx1, Tx2,... Of the cooperative taxi group Tx1, Tx2,.

The coordinate information 21 shown in FIG. 4 is measured and collected by the GPS for each taxi Tx1, Tx2, and the vehicle ID (distribution address 01 in this figure), the date and time of positioning, and the hour, minute, second are used as the current time. Time (Ymmdd-hhmmss in this figure), latitude (N350000 in this figure), longitude (E1350000 in this figure), traveling direction (E in this figure), speed (book) In the figure, it is 00 (parking).
The pattern information 22 is linked to the pattern code of the identification code (01 in this figure), the number of taxis Tx1 and Tx2 that are linked (two in this figure), and the linkage relationship (in this figure, one horizontal line (one line before and after)). Data of contents indicating to be performed) and position numbers (1) and (2) (vehicle ID 01 or 02 in this figure). The maximum value to which position numbers (1) and (2) can be added is the maximum number (N in this figure), which is the maximum number of frames. That is, among the most frequent position numbers (1) to N, only the first two units are used in this example. Such pattern information may be a pixel value, a vector value, a compressed data format, or the like. As for the time lag from the positioning process to the display process, the image information can be corrected, interpolated, deformed, etc., based on the data of the speed and the traveling direction. Ad can be displayed in an integrated manner. Speed data is obtained from taxi speedometers. Further, the traveling direction is measured by an azimuth meter (for example, a magnetic sensor or a gyro sensor).

FIG. 5 is a diagram for explaining the position numbers of the linked taxi group shown in FIG.
In FIG. 5, in the pattern code 22a, the position number (1) indicates the head taxi Tx1 in the traveling direction in the group of linked taxis, and the position number (2) indicates the following taxi Tx2. The array pattern indicated by 22a is a series of two units in the front and rear. In the pattern code 22b of the array pattern in which the three cars are arranged in a horizontal row (front and back), the follow-up taxi Tx3 at position (3) is increased rearward with respect to the array pattern indicated by the pattern code 22a. Further, in the pattern code 22c of the array pattern in which six cars are arranged vertically and horizontally, the following taxi Tx4, Tx5, Tx6 (position numbers (4) to (6)) following the position number (3) with respect to the pattern code 22b. This indicates that the row is arranged on the left side in the traveling direction of the vehicle row indicated by the position numbers (1) to (3).

In the above example, the arrangement pattern is set using the latitude and longitude obtained by the GPS device. In this case, if there is a certain distance between vehicles due to a measurement error expected from the GPS device, the difference in position between each taxi Tx1, Tx2,. When Tx2 ... are parked and parked side by side, or when traveling at low speed, the distance between each vehicle is within the GPS error range, making it difficult to accurately determine the array pattern Become.
Therefore, for example, by using a known positioning accuracy improving method such as differential GPS, it is possible to confirm an accurate arrangement pattern even with GPS.

Here, the function as the cooperative analysis server 2 in the in-vehicle computer system mounted in the taxis Tx1, Tx2,... Uses, for example, a wireless communication device with other taxis Tx1, Tx2,. The identification information (vehicle ID) that can identify the taxi Tx1, Tx2,... And the latitude / longitude measured by the current GPS of the other taxi Tx1, Tx2,. And memorized.
Then, the in-vehicle computer system has a taxi Tx1, Tx2,..., Its own latitude / longitude on which the vehicle-mounted computer system is mounted, for example, within a predetermined distance (for example, 5 m) from the latitude / longitude received and stored. Search for vehicles with latitude and longitude. Then, when there is a latitude / longitude within the searched predetermined distance, the identification information (vehicle ID) and the direction with respect to its own latitude / longitude are determined based on its traveling direction.

  As shown in FIG. 6, in the taxi-mounted computer system shown as (1), for example, one taxi shown as (2) is searched behind in a predetermined distance. On the other hand, in the taxi-mounted computer system indicated by (2) close to the rear of the taxi indicated by (1), one taxi indicated by (1) is searched forward.

In the in-vehicle computer system, an array pattern arranged in front and rear is searched from the array patterns that are set and stored in advance, and the pattern code is acquired.
Further, in the array pattern in which the two front and rear are arranged, the position number of the front taxi Tx1 is 1, and the position number of the rear taxi Tx2 is 2. That is, the relative position of each taxi Tx1, Tx2,... Within a predetermined distance is determined.

  In the above processing, after identifying taxis Tx1, Tx2,... Within a predetermined distance range for each adjacent taxi Tx1, Tx2,..., Data for each taxi Tx1, Tx2,. By sharing, even when taxis Tx1, Tx2,... Are lined up in a long line of a predetermined distance or more (even if they are separated by a predetermined distance or more at the head and tail), a group of taxis Tx1, It is recognized as Tx2. That is, when the arrangement of other taxis Tx1, Tx2,... Around the taxis Tx1, Tx2,... Is specified, there are other taxis Tx1, Tx2,. Each taxi Tx1, Tx2,... Is recognized as a group of taxis Tx1, Tx2,... Together with other taxis Tx1, Tx2,. A group consisting of a plurality of taxis Tx1, Tx2,. Here, two or more groups including the same vehicle ID are combined into one group, and the group further combined is compared with other groups (including groups already combined). When the same vehicle ID is included in each of these groups, the groups are again combined into one group, so that the distance between at least the nearest taxis Tx1, Tx2,. The plurality of taxis Tx1, Tx2,... That are close to each other are regarded as a group of vehicles.

Moreover, when combining a plurality of groups into one, the relative positions of the respective taxis Tx1, Tx2,... In the respective groups before being combined are set as taxis Tx1, Tx2,. The relative positions of the respective taxis Tx1, Tx2,... Within the grouped group, that is, the determined arrangement pattern are determined by combining them so as to overlap each other.
For each taxi Tx1, Tx2,..., The arrangement pattern and the relative position within the arrangement pattern are obtained. Here, as described above, when there is no other taxi Tx1, Tx2,... Close to the periphery (within a predetermined distance), it is determined as a single arrangement pattern.

The in-vehicle computer system functioning as the linkage analysis server 2 includes an array pattern data table in which a preset array pattern and a pattern code are associated with each other, and a relative position (for example, a traveling direction) in each array pattern for each array pattern And a relative position data table in which the position number and the position specified as the number from the front and the position from the right are associated with each other.
A pattern code and a position number for searching the content database 1 are obtained by referring to the arrangement pattern data table and the relative position data table based on the arrangement pattern obtained as described above and the relative position in the arrangement pattern. be able to.

On the other hand, the method for determining the arrangement pattern is not limited to the method using the GPS described above, and for example, the following method can be used.
As shown in FIG. 7, each taxi Tx1, Tx2,... Has a plurality (for example, eight) of directional antennas 31, a wireless communication device 32 connected to the directional antennas 31, and the wireless communication device. And an in-vehicle computer system 33 that functions as the cooperative analysis server 2 connected to the computer.

The directional antennas 31 are respectively arranged radially with the direction of directivity facing outward, and are arranged at an angle (interval) that is an equal angle (for example, 45 degrees).
The wireless communication device 32 is connected to the directional antenna 31 so as to be capable of scanning in order. For example, the directional antenna 31 is sequentially switched and connected to the receiving unit of the wireless communication device 32 every very short time.
Thereby, the radio wave intensity can be measured for each directional antenna 31 and can be compared.

In the wireless communication device 32, radio waves in a predetermined frequency band (hereinafter referred to as measurement radio waves) including identification information (vehicle ID) that can identify itself (each taxi Tx1, Tx2,...) As a digital signal or an analog signal. Is transmitted at a weak predetermined strength.
Therefore, taxis Tx1, Tx2,... Are in a state of transmitting measurement radio waves that can identify themselves and receiving measurement radio waves of other taxis Tx1, Tx2,.

The in-vehicle computer system 33 connected to the wireless communication device 32 receives the radio wave intensity received by the wireless communication device 32 for each directional antenna 31 and the vehicle ID.
In the in-vehicle computer system 33, when the received radio wave intensity (the highest radio wave intensity received by each directional antenna 31) is equal to or higher than a predetermined intensity, another taxi Tx1 , Tx2... Are determined to exist within a predetermined distance. In this case, based on which directional antenna 31 has the strongest radio field intensity, the direction in which the directional antenna 31 has the strongest received radio field intensity is based on the vehicle ID indicated in the measurement radio wave. The directions are specified taxis Tx1, Tx2,. Note that the direction of the directional antenna 31 is the traveling direction of the taxis Tx1, Tx2,. That is, the directional antenna 31 that faces the traveling direction serving as the reference direction is the front, and the directional antennas 31 are the right diagonally forward, right, diagonally backward, back, diagonally backward, left, diagonally forward left, respectively. Is arranged. Further, the direction of the directional antenna 31 having the highest reception strength is not set to the directions of the adjacent taxis Tx1, Tx2,..., But more accurately using the reception strengths of the plurality of directional antennas 31. The direction may be calculated.

Basically, in each taxi Tx1, Tx2,..., There are other taxis Tx1, Tx2,... That are within a predetermined distance range (for example, a radius of 5 m) where the received measurement radio waves have a predetermined intensity. When recognized, the other taxis Tx1, Tx2,... Recognized by the other recognized taxis Tx1, Tx2,... By wireless data communication (for example, using a frequency band different from the measurement radio wave). Share the information of ... Note that the predetermined strength is experimentally determined by, for example, the reception strength when a weak radio wave having a predetermined strength is transmitted at a predetermined distance.
For example, as shown in FIG. 8, the vehicle A as taxis Tx1, Tx2,... Recognizes the vehicle B behind, recognizes the vehicle C on the left side in the traveling direction, and recognizes the vehicle D diagonally left rear. .

Further, the vehicle B as the taxis Tx1, Tx2,... Recognizes the vehicle A forward, recognizes the vehicle D on the left side in the traveling direction, and recognizes the vehicle C diagonally left forward. In addition, the other three vehicles are recognized in the vehicles C and D as the taxis Tx1, Tx2,. By sharing these, it is possible to grasp the arrangement of the four vehicles A, B, C, D (for example, 2 × 2 state vertically and horizontally). As a result, the pattern code indicating the arrangement pattern and the position number indicating the relative position in the arrangement pattern can be specified.
When all the adjacent vehicles A, B, C, and D are recognized as described above, the relative positions of the vehicles in the arrangement pattern and the arrangement pattern in each of the vehicles A, B, C, and D. Can be recognized, and it is not always necessary to share the arrangement pattern by data communication. Further, even when three or more vehicles are arranged in the same direction, it is possible to determine the distance based on the strength of the reception level of the measurement electric field from the same direction and recognize the arrangement order of the vehicles.

However, when multiple taxis are lined up for a long time, the reception level of the measurement radio wave from the last vehicle may not exceed the predetermined intensity in the first vehicle, and one vehicle is close to each other. When all the vehicles in a group cannot be recognized, it is possible to reliably determine the arrangement pattern by sharing the vehicle ID and the arrangement pattern of the vehicles recognized by a plurality of vehicles. That is, as in the case of using the GPS described above, the target vehicles share data, so that the entire vehicle can be specified as a group of vehicles even in a plurality of vehicles in a long row.
A vehicle in which the reception level of the measurement radio wave does not exceed a predetermined intensity is determined as a vehicle having a single arrangement pattern.
As described above, the cooperation analysis server 2 as the cooperation analysis unit specifies the array pattern to which each vehicle belongs, and specifies the relative position of the vehicle in the specified array pattern.

  In addition, from the above, the cooperation analysis server 2 as the cooperation analysis means is provided for each vehicle and is transmitted from each vehicle and the wireless communication device 32 having a plurality of directional antennas 31 directed in different directions. And an in-vehicle computer system 33 as a relative position calculation means for calculating the distance and direction of the vehicles that are close to each other based on the radio intensity of the radio wave received by each directional antenna of each vehicle, and the vehicles that are close to each other And providing an in-vehicle computer system 33 as an array pattern calculating means for obtaining the array pattern and the relative position in the array pattern by sharing data on the direction and distance of the vehicles existing around each vehicle. Become. Note that a radio communication device 32 having a directional antenna 31 and a GPS device are used in combination, and the absolute position is measured by a GPS device that is not particularly highly accurate to identify vehicles that are close to each other, and the relative position is determined by directivity. It is good also as what determines with the radio | wireless communication apparatus 32 provided with the antenna 31. FIG.

  As will be described later, when the linkage analysis server 7 is arranged in a fixed station, the position information by GPS from each taxi Tx1, Tx2,..., The wireless communication device 32 having the directional antenna 31 and the in-vehicle computer. By outputting an array pattern or the like centered on itself determined by the system 33 from the vehicle side to the fixed station side, each vehicle in a state where the data is shared as described above by the cooperation analysis server 7 provided in the fixed station. And the relative position within the array pattern can be obtained.

The frame allocation server 3 searches the content database 1 for the image information 12 corresponding to the pattern information 22 from the advertisement information candidate group, thereby acquiring the corresponding advertisement information 11, as well as the partial image related to each frame. Information 13a, 13b is allocated to each taxi Tx1, Tx2,. As will be described later, when the content database 6, the linkage analysis server 7, and the frame allocation server 8 are arranged in the fixed station, the partial image information 13a, 13b group is transferred to each taxi Tx1, Tx2,.・ It will be delivered to.
And these partial image information 13a, 13b group is displayed as a vehicle body advertisement by each display panel Dsp of taxi Tx1, Tx2, .... Such display panels Dsp are provided on the front, rear, left and right and upper and lower surfaces of the vehicle body such as the roof, bonnet, door, and trunk lid as described above. In addition, the connection to the narrow-area wireless network LAN can be performed through a vehicle-mounted antenna for vehicle-mounted radio.

Here, the in-vehicle computer system 33 as the frame assignment server 3 is based on the vehicle arrangement pattern (pattern code) and the relative position (position number) of the vehicle obtained by the function as the cooperation analysis server 2 as described above. The database constructed in the storage device is searched as the content database 1, the content data corresponding to the pattern code and the position number is read out, stored in the memory for the display panel Dsp, and output to the display panel Dsp for display. It is displayed on the panel Dsp.
That is, the frame allocation server 3 as the content determination unit searches the content storage unit based on the array pattern to which the vehicle specified by the link analysis unit belongs and the relative position in the array pattern, and extracts the content. The frame allocating server 3 as the content allocating unit determines the content retrieved by the content deciding unit based on the arrangement pattern specified by the cooperation analysis unit of the vehicle and the relative position in the arrangement pattern. It is displayed on the display means.

  The above-described processing by the in-vehicle computer system 33 is repeatedly performed every short time, and the content database 1 every time the arrangement pattern to which each vehicle belongs, the relative position, etc. change with the passage of time. A new content is read out from and displayed on the display panel Dsp. As a result, the taxi Tx1, Tx2,... As each vehicle moves, and when the arrangement pattern to which the taxis Tx1, Tx2,. It is displayed on Dsp.

That is, the cooperation analysis server 2 as the cooperation analysis means performs a change in the arrangement pattern to which the vehicle belongs and a change in the relative position in the arrangement pattern based on the change in the position of the taxis Tx1, Tx2,. Monitoring is always performed, and the array pattern and the relative position after the change of each vehicle are output in response to the change of the array pattern and the change of the relative position.
Further, the frame allocation server 3 as the content determination unit searches for and outputs the content from the content storage unit corresponding to the change of the arrangement pattern to which the vehicle belongs and the relative position output from the cooperation analysis unit. become.
Further, the frame allocation server 3 as the content allocation unit replaces the content in accordance with the change in the arrangement pattern to which each vehicle belongs and the relative position in the arrangement pattern based on the content output from the content determination unit. Thus, it is displayed on the display panel Dsp as a display means.

  In addition, a plurality of still data and moving image data are included in one content, and it is possible to switch and display on the display panel Dsp every unit time, and a plurality of taxis Tx1, Tx2,. Can be synchronized between. That is, the frame allocation server 3 as the content allocation unit is configured to be able to display a plurality of contents on the display panel Dsp as the display unit by switching over time, and is synchronized with the display units of other nearby vehicles. The content is switched and displayed.

  Therefore, for example, a taxi Tx1, Tx2,... That is traveling in a state where the relative position is also independent by becoming a single arrangement pattern is another taxi Tx1, Tx2,.・ If the vehicle is close to the vehicle, or if multiple vehicles are parked close to each other at the taxi stand, the content for single travel is used for an array pattern composed of multiple taxis Tx1, Tx2,. Will change to the content. In this case, for example, one image data for a single arrangement pattern changes to a state where it is enlarged and divided into a plurality of units, or when there are only two display items in the case of a single unit, for example. When the number of taxis Tx1, Tx2,... That stop nearby is increased, content having new items can be displayed. For example, when the array pattern is single, the product name and one product image are displayed on the display panel Dsp of one taxi Tx1, Tx2,..., And the array pattern becomes two array patterns. Displays the other two product images on the display panel Dsp of the second taxi Tx1, Tx2,..., And then displays the product specifications on the third unit whenever the number of array patterns increases. It is possible to display the product variation on the fourth unit and the desired retail price on the fifth unit.

  These displays are displayed according to the contents produced in advance by searching the contents stored in the contents database 1 in advance with the arrangement pattern and relative position. That is, it is necessary to produce in advance a content whose display changes as described above and store it in the content database 1 based on the arrangement pattern and the relative position.

In addition, in each of the plurality of taxis Tx1, Tx2,..., The displayed contents may not be seen as one content by combining them, and each is the same content. Also good.
In this case, in the single arrangement pattern, when the taxis Tx1, Tx2,... Displaying different contents are close to each other, it is possible to perform an effect such that the same contents are displayed.

  Further, when a plurality of contents are switched and displayed in a short time, if the taxis Tx1, Tx2,. Although the display order of the contents is different, the taxi Tx1, Tx2,... May be controlled so that the switching timing and the content switching order become the same when they are close to each other.

  In this case, for example, a switching timing synchronization signal is output from one specific taxi Tx1, Tx2... (For example, taxi Tx1, Tx2. In addition to matching the synchronization timing, when the switching order is also input, the control may be performed so that the switching order is set in advance.

In addition, the content is not switched at the same time, but the content is switched in a wave shape by shifting the timing slightly from the head of the taxis Tx1, Tx2,. Etc. In this case, for example, after the synchronization signal from the vehicle having the position number (1) is turned ON, the other vehicles may sequentially switch the contents by shifting the time based on the relative position.
In this example, when taxis Tx1, Tx2,... Are traveling independently, content for a single arrangement pattern is displayed on each display panel Dsp, and taxis Tx1, Tx2,. Then, the display which cooperates mutually is performed on the display panel Dsp of taxi Tx1, Tx2 ... which adjoined. Here, the term “cooperation” refers to a case where the display contents are related to each other. For example, the display may be different displays for the same product, or each divided portion when one display is divided into a plurality of pieces. Alternatively, it includes a display that can be switched at the timing when the same content is linked (same timing, timing shifted every predetermined time, etc.).

By doing in this way, when a plurality of taxis Tx1, Tx2,... Are close to each other, it is possible to perform display with a high effect using each display panel Dsp.
The taxis Tx1, Tx2,... Used here may be, for example, taxis Tx1, Tx2,... Of the same taxi company. For example, a vehicle leasing company that delivers vehicles to each taxi company The equipment necessary for the integrated display system of the present invention is attached to the vehicle in advance and leased to the taxi company, and the vehicle leasing company and the advertising agency contracted with the taxi company contracted with the advertiser, and stored in the content database 1. The content may be stored and stored. Alternatively, an advertising agency may contract with a plurality of vehicle leasing companies, so that even vehicles of different vehicle leasing companies may be vehicles belonging to one integrated display system. In these cases, taxi companies can obtain advertising revenues from advertising agencies, and vehicle leasing companies also receive advertising revenues from advertising agencies, including advertising costs and equipment costs for in-vehicle devices installed in vehicles. Even if a vehicle leasing company does not earn advertising revenue, renting a vehicle from the vehicle leasing company may benefit from the possibility of obtaining many contracts from a taxi company that can obtain advertising revenue. can get.

In the above description, the in-vehicle computer system (including the database storage device) of each vehicle (taxi Tx1, Tx2,...) Has the functions of the content data server 1, the linkage analysis server 2, and the frame allocation server 3. However, as shown in FIG. 9, a content database 6, a linkage analysis server 7, and a frame allocation server 3 as a computer system may be provided on the fixed station side. Reference numeral 6 a is a terminal device for data input to the content database 6, the linkage analysis server 7, and the frame assignment server 3.
Each taxi Tx1, Tx2,... Controls the display panel Dsp, and receives and stores the content determined by the frame allocation server 3 through data communication and displays it on the display panel Dsp. An in-vehicle computer system is required.

  And multiple taxis Tx1, Tx2, etc. belonging to one business unit or a cooperative organization consisting of a plurality of business units or contracted with one vehicle leasing company or advertising agency repeatedly park and pick up On the other hand, it is applied to display contents such as advertisements by linking the display panels Dsp to each other to form an integrated display surface, and the computer center of the relevant business entity (or vehicle sheathed vehicle, advertising agency) Etc. are provided with the above-mentioned fixed stations. In addition, the content database 6 for advertisement, the linkage analysis server 7 connected to the content database 6 through the Internet INT, and the frame allocation server 8 are also included. You may make it the structure which distributes these content databases 6, the cooperation analysis server 7, or the frame allocation server 8 for every business entity, business place, or building. That is, you may provide the content database 6, the cooperation analysis server 7, or the frame allocation server 8 for every area of the above-mentioned area data. Instead of the Internet INT, for example, an extranet such as the business entity, an intranet, or other telecommunication lines may be used. Moreover, it may replace with a taxi and may comprise another structure with the other various registered vehicles.

The content database 6 is responsible for the function corresponding to the content database 1 in this system, and the linkage analysis server 7 and the frame allocation server 8 are provided for each taxi Tx1, Tx2,. By communicating with the vehicle terminal, it is possible to perform functions corresponding to the functions corresponding to the cooperation analysis server 2 or the frame allocation server 3.
In addition, the location information of each taxi is monitored, and image information can be forcibly transmitted from each server, and advertisement information with regularity is sequentially applied to taxis that pass through a certain point. It can also be sent and displayed to make it stand out as advertising information. Furthermore, by instructing a selected taxi or the like to collect, a plurality of vehicles can be linked to display advertisement information. In the display panel Dsp group, a panel that cannot be seen by passengers, passersby, or the like (for example, on the side opposite to the sidewalk) may be added with a function of blocking its display processing to improve efficiency. Furthermore, instead of a taxi, for example, a bus, a garbage truck, a freight car, a train, or other vehicles that operate on a route may be used.

Next, an example of the integrated display method according to the embodiment of the present invention will be described. That is, a software process example will be described with reference to an example of a flowchart shown in FIG. 10 and each of the drawings shown in FIGS.
As a preparatory preparation, the content databases 1 and 6, the linkage analysis servers 2 and 7, and the frame allocation servers 3 and 8 are activated and initialized by a vehicle terminal mounted in a taxi and a management terminal of a computer center. The wireless repeater TRx or the Internet is connected. In addition, advertisement information regarding advertisements in various taxi business areas is registered in advance in the content databases 1 and 6 through the Internet or the like by registration terminals (registration means) such as advertising companies and advertisers. Such software and content may be downloaded through the Internet or distributed on a CD (Compact Disc) ROM or the like for client computers such as vehicle terminals and registration terminals. That is, the contents databases 1 and 6 store and store the contents in advance in association with each item as described above.

  Hereinafter, a case where the content database 1, the linkage analysis server 2, and the frame allocation server 3 installed in each taxi are used (in the case illustrated in FIG. 1) will be described as an example. First, when each coordinate information 11 is collected from all taxis by the collaboration analysis server 2 (step ST2), a group of coordinated taxis is extracted from the current position of these coordinate information 11 (step ST2), and the content database 1 Is selected to select a candidate group of advertisement information (step ST3). Even if the current position of the taxi is determined by positioning with GPS (Global Positioning System), it can be easily determined as the jurisdiction of the wireless network LAN by connecting to the narrow-area wireless network LAN. Also good. As for the cooperative relationship in the cooperative taxi group, it is assumed that a nearby radio wave with a predetermined intensity or more from another taxi is detected by a directional antenna and is within a predetermined distance. It is relatively discriminated that they are adjacent to each other (parallel running, temporary stop, parking, etc.). By exchanging information between these taxis, the taxi that has detected that the head taxi Tx1 discriminates the following taxi Tx2 and does not adjoin the other direction (for example, the traveling direction). An algorithm that functions as a head taxi Tx1 candidate, identifies the vehicle ID, position number, number of linkages, etc. of the adjacent taxi Tx2 groups in order, and analyzes the current position identification, display start, and display end processing in synchronization. May be configured.

  Next, by specifying the pattern information 22 indicating the arrangement of each taxi in the linked taxi group (step ST4), image information is acquired from the advertisement information candidate group (step ST5), and the position position of the position number is obtained. The partial image information is assigned to each vehicle ID (step ST6), and the partial image information is distributed to the distribution address of each vehicle ID (step ST7). Therefore, when such a taxi, instead of taxis, configures a wireless communication network with, for example, an outdoor multi-vision provided on the wall surface of a building, the taxi passes in front of the multi-vision, parks, stops temporarily, etc. Alternatively, the display screens may be integrated by participating in the network of the present system.

FIG. 11 is a flowchart for explaining a specific example of the start and end processes shown in FIG.
In the start process (step ST1), first, each taxi TX1, TX2 performs predetermined initial settings by detecting the approach of another taxi (step ST11). Next, communication with the other taxi is performed to cause the taxi to perform initial setting (step ST12), and then synchronization processing is performed by sharing information between both taxis including the system timer (step ST13). . In the end process (step ST9), first, for example, a set time is displayed on the distributed partial image information on the display panel (step ST91), and then the display is normally ended or the set time is set. Even if the taxi is within the range of the set distance, it is detected that the taxis are distant and distant from each other, and the display is interrupted, and the process ends normally together with a predetermined process for canceling the cooperation (step ST92).

  The above-described integrated display method is an example, and in the integrated display method, a plurality of contents are accumulated and stored in advance in the content database 1 in association with the arrangement pattern and the relative position in the arrangement pattern, as described above. For each vehicle, the arrangement pattern and the relative position within the arrangement pattern are obtained, and the content database 1 is searched based on these to obtain the content. It only needs to be able to display. Further, when the vehicles are separated from each other by a predetermined distance or more, the content searched for based on the single arrangement pattern as described above may be displayed instead of ending the display.

Also, as described above, when searching for content from the content database, in addition to the pattern code and position number, the time obtained by the clock set in the in-vehicle computer, the area obtained by the above-described position measuring means, etc. Are input to the above-described content database 1 area data (latitude / longitude data to be an area range) and timer data (each time zone when a day is divided into a plurality of time zones). Content may be selected, so that, for example, in areas such as Shinjuku, Shibuya, Ginza, etc., it is possible to display content that is advertisements for stores in that area, and for example, corresponding to store opening hours You can display content that will serve as store advertisements.
That is, the taxi Tx1, Tx2,... Has a GPS or the like as a position measuring means for measuring the absolute position, and a function as a time measuring means for measuring the current time in the in-vehicle computer system. As described above, the contents are classified and stored for each arrangement pattern and relative position, and are classified and stored for each region (area) and time range (timer data). , Based on the relative position, the area (area data) to which the vehicle position measured by the position measuring means belongs, and the current time (time within the time range set in the timer data) measured by the time measuring means. The contents database 1 is searched to extract contents.
The timer data is set, for example, as 0 to 5 o'clock, 6 to 10 o'clock, 10 to 15 o'clock, 15 to 19 o'clock, 20 to 24 o'clock, etc. , The data set at 15:00 to 15:00 is retrieved. The area data may be set as latitudes ab and longitudes cd, for example, or the latitude and longitude may be registered as an area range such as a municipality or a ward on the map data. Good.

Next, display processing of contents on the display panel Dsp in the customer waiting parking spaces of taxis Tx1, Tx2,... According to the present invention will be described.
Here, a taxi pool at a main station where many taxis Tx1, Tx2,...
Here, as shown in FIG. 12, the taxi pool 41 is 5 × 5, that is, five cars can be parked in one row, and the taxi pool 41 consists of five rows. That is, in the taxi pool, 25 stop spaces 42... Are composed of 5 columns and 5 rows as a plurality of stop spaces 42. Here, the columns are the front and rear rows along the traveling direction of taxis Tx1, Tx2,..., And the rows are the left and right rows perpendicular to the traveling direction of the taxi.

  In FIG. 12, in order to explain in more detail, each stop space 42... Is given a code from 1 to 5 in each column, and a code from a to e in each row. -5, b1-5, c1-5, d1-5, and e1-5. Also, among the taxis Tx1, Tx2,..., Those that have already gone out of the front line are marked with a Z symbol, and the taxi Tx1, Tx2,. The lines A to E are assigned to the respective lines corresponding to the lines, and the taxis Tx1, Tx2,. Each taxi Tx1, Tx2,... Can be labeled Z1-5, A1-5, B1-5, C1-5, D1-5, E1 by attaching Tx1, Tx2,. Signs of ˜5 and F1˜5 were attached.

Further, in this taxi pool 41, the taxi stand of the station is arranged on the front side of the traveling direction of taxis A to E so that taxis A to E depart from the front side of the taxi pool 41 toward the taxi stand. It has become. Therefore, the taxis F1 to F5 that are newly waiting in the taxi pool enter the taxi pool 41 from the rear side of the taxi pool 41.
Further, in the taxi pool 41, for example, after the taxi A1 located on the leftmost side heads for the taxi stand, the taxi pools A2 and A3 on the right are sequentially arranged along the line A (left and right direction). , A4, A5 are going to the taxi stand. In other words, the frontmost taxis A1 to A5 go out of the taxi pool 41 in order from the left to the right toward the taxi stand.

  In addition, as described above, whenever the first taxi A1-5 exits from the taxi pool 41, the taxi B-E lined up behind and behind the taxi A1-5, which will exit the taxi pool, sequentially corresponds to one stop space. Only to go forward. That is, in the row where the first taxi A1, for example, has left the taxi pool 41, the next taxi B1 enters the first stop space a1 vacated by the first taxi A1 leaving, and the next taxi B1 is the previous stop space. The next taxi C1 is further moved to the next stop space b1 vacated by the movement to a1, and the taxis B1, C1, D1, E1 arranged in a line are sequentially moved forward.

  If taxi A5 comes out of the taxi pool from the rightmost side of the front line, then taxi B1 comes out again from the left side of the front line. In this case, taxis A1 to 5 have already come out, and taxis B1 to B5 stopped in the stop spaces b1 to 5 immediately after the taxi B1 to 5 are moved forward and packed. Since the frontmost stop spaces a1 to 5 are filled, the leftmost taxi B1 on the frontmost row is newly headed to the taxi stand.

  On the other hand, taxis F1-5 newly entering the taxi pool 41 have, for example, (the stop space d1-5 that is the fourth line from the front and the stop space e1-5 that is the fifth line (last line)). And the leftmost stop space d1 in the line that is the most rearward when entering, in order to enter right next to the taxi F1-4 that entered in order, and enter the rightmost When the taxi F5 enters the stop space d5, a taxi (not shown) enters the leftmost stop space e1 in the next row. When the taxi pool 41 is full, the frontmost taxis A1 to A5 go out as described above, and the taxi B to E behind them is put forward, and the stop space becomes the last available vacant space. Taxi F1-5 will enter e1-5 sequentially from the left side.

  Here, the content databases 1 and 6 as the content storage means are for taxis having a taxi pool 41 having the aforementioned stop space 42 to which the present invention is applied and a stop space 42 provided in a line in front of the taxi stand. A plurality of contents are stored corresponding to each parking space, that is, corresponding to the stopping spaces 42 that are close to each other and form a group. In other words, content is stored for each taxi stop at each doorway of each station. Further, a plurality of contents for a plurality of stopping spaces in a group are stored in the content databases 1 and 6 in association with each stopping space. For example, a taxi parking pace in front of a specific taxi pool or taxi stand Are designated as identification information (for example, parking code assigned to each taxi pool or taxi parking space), and these taxi pools are set for each identification information (parking code). In addition, by designating a stop space code assigned to each of a plurality of stop spaces 42... Which is a group in a taxi parking space, the content databases 1 and 6 can be searched and extracted.

That is, in the above example, the content can be searched from the content database 1 using the pattern code and the position number. Here, the parking code is used, for example, a taxi parking space at a taxi stand at Tokyo Station Yaesu Exit, etc. Is specified, and the stop space code is used to specify the stop space of which column and the content, so that the content can be searched.
In the above example, the content can be searched by specifying the area code and timer code in addition to the pattern code and position number. However, in this case, the area is limited by the parking lot code. There is no need to register the content in association with the code. In order to change the content to be displayed in the time zone, it is necessary to register the content in association with the timer code indicating the time zone.

  Therefore, in this example, content is stored in the content database 1 in association with the parking lot code, the stop space code, and the timer code. In addition, since the shape of each taxi pool 41 and the taxi parking space (for example, how many taxis can be parked in each row) is determined by the parking lot code, the parking lot code corresponds to the arrangement pattern. Moreover, the stop space code corresponding to each stop space in the taxi pool 41 or the taxi parking space is a group of taxis Tx1, Tx2,... Stopped in each stop space 42 in the taxi pool 41 or the taxi parking space. The relative position in the taxi pool 41 and the taxi parking space is indicated.

Further, in order to switch contents in a relatively short time, it is necessary to store a plurality of contents so as to be switched in association with a parking lot code, a stop space code, and a timer code, for example. In this case, the content display order needs to be stored in the content databases 1 and 6 in association with the content. There may be a plurality of types in the display order, and there may be a setting in which the display order is random.
In addition, from the above, the content database 1 functions as a content storage unit that stores and stores content to be displayed on the display unit in association with each of a plurality of stopping spaces for the vehicle. Further, the content databases 1 and 6 store and store a plurality of contents for switching for each stop space.
The content databases 1 and 6 may be installed in each of the taxis A to E. For example, the content databases 1 and 6 are provided in fixed stations provided in the vicinity of the taxi pool 41 or the taxi parking lot and use wireless communication. It is good also as what is delivered to each taxi AE by the data communication which had been.

Moreover, in order to specify in which stop space a to e the taxis A to E stop, position detection means for detecting the positions of the taxis A to E is necessary. E has a differential GPS function capable of accurately assuming an absolute position, and if a differential GPS fixed station is provided, a stop in which the longitude and latitude range of each stop space is associated with the stop space code The stop space code can be obtained using the space data table and the latitude and longitude output from the GPS devices of taxis A to E.
At this time, the above-described parking lot code is also specified. That is, the stop space is located in any taxi pool 41 or taxi parking lot specified by the parking lot code, and the stop space code and the parking lot code are based on the latitude and longitude output from the GPS device. Both will be identified. That is, the parking space code needs to be included in the stop space data table.

Note that the position detection means is not limited to this. For example, each taxi A to E is attached with a wireless tag or a wireless tag reader, and each stop space a to e is attached with a wireless tag or wireless tag. A reader may be attached.
When the radio tags are attached to the taxis A to E, the vehicle code data that can identify the taxis A to E is output from the radio tags, and the vehicle code is read by the reader provided in the stop spaces a to e. Make it read.

  At this time, assuming that each of the taxis A to E is equipped with an in-vehicle computer system having the functions of the content database 1, the content determination means, and the frame assignment server 3 as the content assignment means, the stop spaces a to e A stationary station code corresponding to the stationary space a to e provided with a reading device that reads a vehicle code from a wireless tag by providing a fixed station correspondingly and providing a wireless communication device, a computer system, etc. in the fixed station And the read vehicle code to the in-vehicle computer system via the wireless communication device provided in the taxis A to E, it is possible to recognize which stop space a to e in the taxi A to E can do.

  If the computer system functioning as the content database 1 and the frame allocation server 3 is arranged in the fixed station, the stop space code in which the reading device is installed in the fixed station from the reading device of the wireless tag, and the read vehicle code Is output, it becomes possible to specify the taxi A to E stopped in the stop spaces a to e and the stop space where the taxi A to E stopped.

  In addition, a wireless tag is provided in the stop spaces a to e, and a stop space code (including a parking lot code) for identifying the stop spaces a to e is output from the wireless tag, and the wireless tag is output to the taxis A to E. When the taxi A to E is provided with an in-vehicle computer system that functions as the content database 1 and the frame assignment server 3, the stop space code read by the reading device is provided. And the content can be searched by taxi A to E by the parking lot code.

  In addition, a wireless tag is provided in the stop spaces a to e, and a stop space code (including a parking lot code) for identifying the stop spaces a to e is output from the wireless tag, and the wireless tag is output to the taxis A to E. When the fixed station is provided with a computer system that functions as the content database 1 and the frame allocation server 3 described above, the taxi A to E are connected to the fixed station by wireless communication. The stop space code and the parking lot code may be output to the vehicle.

  In addition, it is not always necessary to provide wireless tags or wireless tag readers in all stop spaces. For example, the wireless communication device 32 having the directional antenna 31 described above and the in-vehicle computer system 33 that identifies the relative position of each taxi A to E based on the output from the wireless communication device 32 are read from the wireless tag and the reading device described above. You may make it combine with the detection method of the position by an apparatus.

For example, a wireless tag or a wireless tag reading device is provided in one stop space a to e serving as a reference for a taxi pool 41 or a taxi parking space, and the taxi A to stop in the stop space a to e as described above. E and the stop spaces a to e where the taxis A to E stop are specified, and the taxi A to E stopped in the reference stop spaces a to e are specified, and the directional antenna 31 described above is specified. By specifying the relative position of the taxis A to E existing around the reference stop spaces a to e using the wireless communication device 32, which taxi A to E is located in which stop spaces a to e. You can ask if it is stopped.
For example, it is assumed that a radio tag is provided in the stop space a1, and each taxi A to E includes a reading device, the above-described directional antenna 31, the wireless communication device 32, and the in-vehicle computer system 33.

Here, when the taxi A1 stops in the stop space a1, the reading device provided in the taxi A1 reads the stop space code and the parking lot code output from the stop space a1, and the stop space a1 which is the basis of the specific taxi pool 41 It will be recognized that the car has stopped. Here, the taxi A1 detects the surrounding taxi as described above using the wireless communication device 32 having the directional antenna 31 when the other taxis A to E stop in the taxi pool 41. That is, the taxi A1 detects the taxi A2 right next to it, detects the taxi B1 behind, and detects the taxi B2 diagonally right behind. In addition, the taxi A2 detects the taxi A1 on the left, detects the taxi A3 on the right, detects the taxi B2 on the rear, detects the taxi B1 on the left rear, and detects the taxi B3 on the right rear. Will do.
In addition, in each taxi A to E that stops in this taxi pool 41, all the taxis A to E around it are specified, and information on the taxi A to E around each taxi A to E is described above. As described above, by sharing each taxi A to E or the fixed station, the arrangement pattern of all the taxis A to E in the taxi pool 41 can be determined as described above.

With the arrangement pattern determined in this way, the reference stop space a1 and the arrangement of the stop spaces a to e, the taxi A1 stopped in the stop space a1 and the taxi A to be a group including the taxi A1 By comparing with the arrangement of E, it is possible to recognize which taxi A to E are stopped in which stop spaces a to e. For example, in FIG. 12, the arrangement of the stop spaces a to e is five rows and five columns with the stop space a1 that is the leftmost in the foremost as a reference point.
Moreover, when all the taxis A to E stop in these stop spaces a to e, the arrangement of the taxis A to E becomes 5 rows and 5 columns with the taxi A1 which is the leftmost in the front as a reference point, and each stop space a -E and each taxi A-E respond | correspond, and it can identify which taxi A-E stopped to which stop space a-e.

  As described above, when the taxis A to E stop in the motor pool 41, the stop spaces a to e where the taxis A to E have stopped are specified in the above example. This corresponds to the processing for obtaining the position, and is performed as processing of the cooperative analysis servers 2 and 7. Then, as the processing of the cooperative analysis servers 2 and 7, when the vehicle (taxi A to E) stops in any of the plurality of stop spaces a to e, the stop spaces a to e where the vehicle stops are specified. Will do.

  Next, when it is specified that the taxis A to E have stopped in any of the stop spaces a to e as described above, that is, the parking lot code and the stop space code are determined for the taxis A to E. In addition, in the in-vehicle computer system as the frame allocation server 3 or the fixed station computer system as the frame allocation server 8, the content databases 1 and 6 are searched to extract the contents to be displayed on the display panels Dsp of the respective taxis A to E. To do. Then, the content is output and displayed on the display panels Dsp of the respective taxis A to E. The method for displaying the content on the display panel Dsp is the same as that in the above-described case, that is, the case where the content is assigned to each taxi A to E based on the arrangement pattern and the relative position.

Hardware of the content server 1, the linkage analysis server 2, and the frame allocation server 3 as the in-vehicle computer system installed in the taxis A to E, and the content server 6, the linkage analysis server 7, and the frame allocation server 8 as the computer system of the fixed station The configuration is basically the same as in the above case, and the processing method is only different as described above.
In addition, when assigning content to the display panels Dsp of the respective taxis A to E, the content may be switched every short time in the same manner as described above. In this case, for example, in all taxis stopped in the taxi pool 41 The contents may be switched all at once, for example, the contents may be switched in the above-described wave shape in the order of A line, B line, C line,..., 1 column, 2 columns, 3 columns,.・ The content may be switched to a permanent wave in the order of.

  Furthermore, in the taxi pool 41, the taxis A to E stop in a plurality of rows, so that, for example, the content may be switched in a wave shape obliquely from the corner of the taxi pool 41 to a diagonal corner. That is, the content of the taxi A1 may be switched, then the content of the taxis B1 and A2 may be switched, and then the content of the taxis C1, B2 and A3 may be switched diagonally in a wave shape.

  As described above, the in-vehicle computer system or the fixed station computer system includes a content determination unit that searches the content storage unit based on the stop spaces a to e specified by the position detection unit, and extracts content. It functions as content allocating means for displaying the content extracted by the content determining means on the display means of the vehicle.

Here, in the taxi pool 41, the taxis A1-5 stopped in the frontmost stop spaces a1-5 as described above do not go to the taxi stand sequentially, and the back of the vacant stop spaces a1-5 The taxi B1-5 advances from the stop space b1-5 and stops in the vacant stop space a1-5. On the other hand, from the rear of the taxi pool, taxis F1 to F5 enter the taxi pool 41 sequentially.
During this time, when the above-mentioned position detecting means is composed of the above-mentioned wireless tag and its reading device, and the reading device is on the stop space a to e side, the computers of taxis Z1 to 5 that have exited from the taxi pool 41 from the reading device side For the system, there is no corresponding stop space a1-5 via radio (no reading device of stop space ae reads the taxi code of the radio tag of the corresponding taxi Z1-5) The taxi A to E that has advanced one by one is notified that the stop spaces a to e have been changed, that is, a new stop space code, and has entered the taxi pool 41 newly. 5 is notified of a new stop in the stop spaces e1 to 5, that is, a stop space code.
On the other hand, when the reading device is on the taxi A to E side and the wireless tag is in the stop space a to e, the stop space code registered in the wireless tag can be read in the taxi Z1 to 5 coming out of the taxi pool 41 In the taxi A to E newly entering the stop spaces a to e or moving between the stop spaces a to e, a new stop space code is read.

  Based on this, the frame allocation servers 3 and 8 stop displaying the content corresponding to the stop spaces a1 to 5 on the display panel Dsp for the taxi Z15 that has exited from the taxi pool 41, as described above. The content based on the arrangement pattern of taxis Tx1, Tx2,... Adjacent to the surroundings and the relative position in the arrangement pattern is displayed. The taxis Tx1, Tx2,... That have just left the taxi pool 41 are likely to merge with subsequent taxis Tx1, Tx2,. Will display content as a taxi.

On the other hand, in each taxi A to E that has moved in the taxi pool 41 by one stop space a to e before, the content displayed on the display panel Dsp is switched each time it moves. In this case, the contents displayed on the previous taxis A to E are sequentially displayed on the rear taxis A to E.
Further, the taxis F1 to F5 newly entering the taxi pool 41 correspond to the stop spaces e1 to 5 from the state in which the content is displayed based on the arrangement pattern and the relative position in the arrangement pattern as described above. Content will be displayed.

  Therefore, the above-described position detection means constantly monitors the stop spaces a to e where the vehicle is located, and if any of the stop spaces a to e where the vehicles (taxi A to E) are changed and any When the vehicle is located in the stop space a to e, the stop space a to e where the vehicle is newly stopped is specified, and the content determination unit is configured to store the content storage unit based on the newly specified stop space a to e. The content allocating means searches for and outputs the content, and the content allocating means outputs the content in response to changes in the stop spaces a to e where the vehicle stops due to the movement of the vehicle based on the content output from the content determining means. It is replaced and displayed on the display means (display panel Dsp).

The displayed content is the same as when the content is displayed based on the arrangement pattern and the relative position in the arrangement pattern, and the arrangement pattern becomes a plurality of columns. Because the number of taxis A to E in a group increases, outside the taxi pool 41, more items are displayed or larger images are divided than in the case of taxis Tx1, Tx2,. Can be displayed.
Moreover, in the taxi parking space that is in a line in front of the taxi stand, it is the same as the case where content is displayed on taxis Tx1, Tx2,... Arranged in a line based on the above-described arrangement pattern and relative position. In the taxi parking space, the taxi parking space for the first taxi Tx1, Tx2,... Will come out sequentially, and taxis Tx1, Tx2. In doing so, a process corresponding to one row in the above-described taxi pool 41 may be performed.

  In the taxi pool 41 and the taxi parking space as described above, the contents are associated with the stop spaces a to e that are fixed to the vehicle, so that each taxi A to E moves as the taxi A to E moves. The content displayed in E will be switched, but the content itself will be displayed in almost the same place, and the content does not move, but the taxis A to E that display it move are interesting. It is possible to display content for production.

  In the taxi pool 41 and taxi parking space, depending on the time of day and the weather, there may be frequent occurrences even when taxis A to E stop only in half or less of all the stop spaces a to e. There is. Therefore, when content is stored and stored in the content database 1 described above, in addition to the parking lot code, the stop space code, and the timer code, the number currently parked in the taxi pool 41 or the taxi parking space is set to, for example, 1 -10, 11-20, 20-25, and so on, and the content may be associated with the number of vehicles in stages.

  For example, in the taxi pool 41, different contents can be displayed when the number of vehicles is 1 to 10, when the number of vehicles is 11 to 20, and when the number of vehicles is 20 to 25. Even when there are few taxis A to E stopping in the taxi pool 41, it is possible to prevent a state where only a part of the content that should be displayed is displayed for a long time.

Also, depending on the time of day and the weather, there may be a small number of passengers on taxis A to E and no taxi movements will continue for a long time. In this case, the content is switched as described above. In particular, by switching all at once or switching to a wave shape, it is possible to perform display with high performance such as neon display. Thereby, it is possible to prevent the degree of attention from decreasing due to the small movement of taxis A to E.
In addition, the taxi pool 41 and the taxi parking space are located near the station building, so the taxis A to E can be seen from the windows of station buildings and buildings around the station, especially restaurants and other restaurants. it can. Therefore, content can be effectively displayed when the display panel Dsp is provided on the top surfaces of the roofs, bonnets, trunks, etc. of the taxis A to E.

Further, in the taxi pool 41, when the taxis A to E are extremely close to each other in the front, rear, left and right directions, the display panels Dsp provided on the top surfaces of the taxis A to E are very close. Even when the display panel Dsp is divided and displayed on the E display panel Dsp, the distance between the display panels Dsp is short, so that highly recognizable display can be performed.
In addition, since a certain number of taxis A to E are concentrated, for example, it is possible to display large letters and marks with each taxi A to E as one pixel.

  It should be noted that in the in-vehicle or fixed station computer system having functions as the above-described content database 1, cooperation analysis server 2, and frame allocation server 3, processing is performed by an input program. In order to perform the above-described processing, the computer system accumulates and stores contents to be displayed on the display means in association with a plurality of stopping spaces for the vehicle that are close to each other based on a program; When the vehicle stops in any of the plurality of stop spaces, a step of specifying a stop space where the vehicle stops, and a search is made for content stored and stored based on the specified stop space, and content is extracted And executing the extracted content. Further, the above-described processing performed by the computer system in the above example is executed based on a program.
