Description

  The present invention relates to an integrated display system, method, and program. For example, a display unit is provided on the body of a vehicle such as a taxi or other moving body, and a system such as a local advertisement is displayed on the display unit. Can be applied to the method.

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) In addition, taxis do not reciprocate or circulate around a certain section like a route bus, but travel around various shopping districts in response to customer demands and travel relatively widely. 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 an image or video as a so-called commercial content is displayed on the display, it is rare at first, but it may get bored immediately. Therefore, there is a need for a medium that can perform various expressions so that it can be devised to stand out depending on the idea, and the expression method can be changed sequentially when tired.

  The present invention has been made in view of the above circumstances, and an integrated display system capable of displaying content having various sizes and shapes conspicuously and in a timely manner on a display surface having a limited area. An object is to provide a method and a program.

In order to achieve the object, the integrated display system according to claim 1 is configured such that when a plurality of vehicles provided with display means on the surface of a vehicle body are close to each other, the display means of the plurality of vehicles are integrated. An integrated display system for displaying related contents as a group of display means,
In the vehicle,
Content stored on the display means in association with an array pattern indicating the number of the vehicles in a group close to each other and the arrangement of the vehicles in the group and the relative position of the vehicles in the array pattern Storage means;
A GPS device for measuring the absolute position of the vehicle;
A wireless communication device for performing data communication with the other vehicle, having a plurality of directional antennas directed in different directions, and measuring a relative position of a group of vehicles close to each other;
A measurement radio wave transmitting means for transmitting a weak measurement radio wave including identification information that enables identification of the vehicle from the wireless communication device as a signal;
A group of the vehicles adjacent to each other from an absolute position measured by the GPS device and an absolute position measured by the other vehicle input by data communication via the wireless communication device;
And the distance to the own vehicle of the other vehicle belonging to the group of the vehicles close to each other from the reception intensity of the measurement radio wave received by each directional antenna and the identification information included in the measurement radio wave The relative position of the vehicle and the relative position of the other vehicle measured by the host vehicle, and the other of the other vehicles included in the group of the vehicles that are input by data communication via the wireless communication device A collaborative analysis means for identifying a group of vehicles arranged close to each other to which the host vehicle belongs from the information on the relative position measured by the vehicle, and a relative position of the host vehicle in the array pattern;
Content determination means for searching the content storage means and extracting content based on the array pattern to which the host vehicle specified by the cooperation analysis means belongs and the relative position of the host vehicle in the array pattern;
Content allocation means for displaying the content extracted by the content determination means on the display means of the own vehicle is provided .

In the first aspect of the present invention, the moving body is provided with display means, and the content is displayed on the display means. In addition, when the moving bodies provided with the display means come close to each other within a predetermined distance, for example, it is possible to perform integrated display between adjacent vehicles.
That is, the content displayed on the display means indicates the number of the moving objects that are close to each other and have the display means and the arrangement of the moving objects, and a plurality of preset arrangement patterns and the arrangement patterns For example, a plurality of display means (displays) are arranged side by side as content for a plurality of vehicles traveling or parked in a row. In a state, related contents can be accumulated so as to be displayed side by side on each display.

Then, when actually displaying, if a plurality of moving objects are arranged close to each other, the content storage means can change the contents based on the number of the moving objects arranged and the arrangement pattern indicating the arrangement. Can be retrieved and displayed on the display means of each moving object. At this time, the content corresponding to the relative position in the array pattern of each moving body is displayed on the display means of each moving body. That is, when a plurality of mobile objects are arranged in a line, the contents displayed on the display means of the mobile objects can be different in the order of arrangement.
In addition, since the arrangement pattern indicates the number of moving objects and how the moving objects are arranged, for example, the content is different between when two moving objects are arranged in front and back and when three moving objects are arranged in front and rear. It can be arranged in the front-rear direction along the traveling direction, in the left-right direction orthogonal to the traveling direction, in the case of an array that is oblique to the traveling direction, and in the case of a zigzag array The contents to be displayed can be changed depending on the case where the matrix is arranged in a plurality of columns.

  Therefore, in a state where a plurality of moving bodies are close to each other, content that cannot be displayed with the size of the display means of one vehicle can be distributed and displayed on the display means of the plurality of moving bodies. Therefore, for example, when a moving body is a vehicle, even if it is a passenger car instead of a bus or a truck that can install a large display as a display means, by combining each display means installed in a plurality of vehicles, A lot of information (items) can be displayed, and each information (item) can be displayed in a large size.

For example, when a vehicle provided with display means is traveling alone, a small number of items are displayed in a small size on the display means, and a plurality of vehicles are approaching from a state where the vehicle is traveling alone. When the vehicle is in a traveling state, for example, a state where a small number of items are displayed is changed to a state where a large number of items are displayed using a plurality of display means, or a plurality of items displayed on one vehicle are displayed. Each item can be displayed on a large screen.
Further, by switching between displaying the same content on a plurality of moving bodies or displaying different contents, attention can be directed to the contents displayed on the display means of the moving body. That is, even if the same image is displayed on the display means of each moving body, if many moving bodies are gathered, it becomes a target of attention, and furthermore, those images are switched simultaneously, the contents are randomized, Various productions are possible by unifying them.

Here, the moving body can be a transportation means such as a vehicle, a train, a ship, an airplane, etc. In addition, for example, a display means that is attached to a person, an animal, etc. and moves together with the person or animal The apparatus provided with is also included.
Further, when the moving body is a vehicle, for example, a commercial vehicle such as a taxi or a hire is preferable, and a commercial vehicle using a leased vehicle is particularly preferable. If the vehicle is a leased vehicle, the present invention can be applied to vehicles of a plurality of companies by leasing a vehicle provided with display means or the like in advance, without being limited to the company that uses the vehicle.
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. Note that an audio generation device (audio generation circuit, audio reproduction circuit, amplifier, speaker) may be provided in the moving body in addition to the display means, and the audio data may be included in the content.
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 mobile body, or provided in the fixed station, and the searched content can be output to the mobile body by data communication between the mobile body and the fixed station. It may be.
In addition, when the content storage means is in the fixed station, the mobile body needs storage means for temporarily storing the content output from the fixed station.

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.
For example, the linkage analysis unit may have a configuration as described in claim 2 described later and specify the relative position in the array pattern by measuring the relative position, For example, absolute position measuring means such as GPS may be provided for each moving body, and the array pattern and the relative position in the array pattern may be specified based on the absolute position of each moving body.

  In other words, the linkage analysis unit is arranged on each moving body, based on the position of the moving body measured by the position measuring unit that measures the relative position and absolute position of each moving body, The position in the pattern is specified. The position measuring means does not necessarily have to be mounted on the moving body, and includes a device for recognizing the moving body from structures such as satellites, airships, buildings, etc., thereby measuring the position of the moving body (remote sensing ). Further, when a GPS is provided as a position measuring means, for example, an inertial navigation device or the like is used together, or a method for improving the measurement system using a GPS device of each moving body and a GPS of a fixed station (differential GPS or the like), etc. It is necessary to improve the positioning accuracy using.

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 the integrated display system, a fixed station having content storage means is provided, data communication is performed between the fixed station and each mobile unit, and an arrangement pattern or the like is specified by the fixed station. It is good also as a structure (centralized type) which distributes to a mobile body.
Also, each mobile unit is provided with content storage means without providing a fixed station, and the arrangement pattern of each mobile unit is obtained by data communication between the mobile units, and the content storage unit is searched for each mobile unit to extract the content. And the structure (distributed type) which displays the content extracted at the display stage may be sufficient. In this case, the content data is distributed and stored in the storage device (storage means) serving as the content storage means of each mobile body so that the content data is shared by each vehicle in the integrated display system. It is good also as what transmits / receives content between each vehicle as needed.

In addition, each mobile object outputs a radio wave having a specific frequency, for example. Each moving body receives radio waves transmitted from other moving bodies with a plurality of directional antennas directed in different directions. At this time, the radio wave intensity of each directional antenna is measured by sequentially switching each directional antenna connected to the receiving unit of the wireless communication apparatus.
In this case, the reception intensity of the directional antenna having a direction close to the direction from the reception-side mobile body to the transmission-side mobile body is stronger than the reception intensity of other directional antennas.
As a result, it is possible to specify the approximate direction of another vehicle located in the vicinity of the specific vehicle from the direction of the directional antenna and the radio wave intensity level received by each directional antenna when the specific vehicle is the center. it can.

In addition, since the reception intensity described above is inversely proportional to the square of the distance between the mobile body on the transmission side and the mobile body on the reception side, for example, radio waves transmitted from other mobile bodies are equal to or higher than a predetermined radio wave intensity level. In such a case, it is possible to perform control such that another moving object is in proximity within a predetermined distance range.
Further, by dividing the radio field intensity level equal to or greater than the predetermined radio field intensity level, a rough distance such as near or far can be determined within a predetermined distance range.

Further, if information that can identify each vehicle is included in the radio wave transmitted from each vehicle, it is possible to specify a vehicle in the vicinity of each vehicle.
And in each adjacent vehicle, the vehicle group which adjoins by sharing the information which specifies the vehicle located in the vicinity of each vehicle each measured, and the approximate direction and distance of the specified vehicle by each vehicle The arrangement pattern can be obtained.

The wireless communication device is capable of data communication and can specify the approximate direction and distance of the radio wave source using a directional antenna, that is, the reception intensity can be measured for each directional antenna It has the structure.
The relative position calculation means is composed of a computer system connected to the wireless communication device, and calculates the distance and direction of the transmission source from the radio wave intensity of each directional antenna described above. The array pattern calculating means is composed of a computer system connected to the wireless communication apparatus. For example, the moving body A detects the moving body B behind it and the moving body B detects the moving body A before it. When the moving body C is detected behind and the moving body B is detected in front of the moving body C, by sharing these data, the three moving bodies A, B, C move in a row. It is specified that A, the moving body B, and the moving body C are arranged in this order.
Note that the relative position calculation means and the array pattern calculation means may be configured by one computer system.

The invention according to claim 2 is the integrated display system according to claim 1 ,
The linkage analysis unit is configured to change the arrangement pattern to which the own vehicle belongs and the arrangement pattern based on a change between the relative position of the own vehicle to be measured and the relative position of another vehicle input via the wireless communication device. The relative position of the vehicle is constantly monitored, and the array pattern after the change of the vehicle corresponding to the change of the array pattern and the relative position of the array pattern and the relative position of the host vehicle within the array pattern Output
The content determination means searches for and outputs the content from the content storage means corresponding to the change of the arrangement pattern to which the host vehicle belongs and the relative position output from the cooperation analysis means,
The content allocating means replaces the content in accordance with the change of the relative position in the arrangement pattern to which the host vehicle belongs and the arrangement pattern based on the content output from the content determination means, and causes the display means to display it. Features.

In the invention according to claim 2, when the arrangement pattern to which each vehicle belongs or the relative position in the arrangement pattern changes, contents corresponding to the changed arrangement pattern and relative position are displayed. For example, when the order of the moving objects is changed in the moving objects arranged in the front and rear, the displayed content is changed accordingly. In this case, the order of the content changes or is likely to change due to the change of the order of the moving body, but the content displayed on the display means is changed along with the change of the relative position of the moving body, The previous state will be maintained. That is, although the order of moving objects is changed, the effect of producing effects is produced by changing the order of displayed contents so as to be maintained in a state before the order of moving objects is changed.
That is, when the arrangement pattern is the same and only the relative position is changed, the arrangement of each moving body is changed, whereas the positional relationship of the displayed contents is changed so as to be maintained as it is. It will be.
In addition, when mobile bodies that have traveled independently approach each other, content changes when a group of a plurality of mobile bodies is formed. In other words, the image displayed on one display means is displayed separately on two display means that have come close to each other, or the image combined with the image displayed on one display means is approaching another An effect of displaying the same image by being displayed on the display means or when the two display means are separated from each other and are displaying different images can be displayed.

The invention according to claim 3 is the integrated display system according to claim 1 or 2 ,
It has timekeeping means to keep the current time,
The said content storage means, together with the content is accumulated is classified into the arrangement pattern and each of the relative positions, are stored after being classified by region and time range,
The content determination means searches the content storage means based on the arrangement pattern, the relative position, the region to which the position of the vehicle measured by the GPS measurement device belongs, and the current time measured by the time measurement means to search for the content Is extracted.

In the third aspect of the present invention, the contents can be selected and displayed on the display means by region or time. For example, in Tokyo, in each area such as Shinjuku, Shibuya, Ikebukuro, and Ginza, information on stores in the area can be displayed when the area is moved. In addition, when the contents to be displayed separately in the morning, noon, and evening are changed, for example, a coffee shop advertisement is displayed in the morning, a restaurant advertisement is displayed in the day, and a bar advertisement is displayed in the evening. It can be carried out.
In this case, a fixed station is provided for each region, and content storage means for storing content corresponding to each region is arranged in the fixed station, thereby facilitating display of content by region. Also, in the case where each mobile unit is provided with content storage means, the content storage means installed in each mobile unit can be divided into many regions by adopting a configuration in which content is downloaded from a fixed station provided in each region. Therefore, it is not necessary to always store the contents, and the capacity of the contents storing means can be reduced.

The invention according to claim 4 is the integrated display system according to any one of claims 1 to 3 ,
The content allocating means is configured to be able to switch a plurality of contents every time and display on the display means, and by means of a synchronization signal output from a specific vehicle of the group of vehicles adjacent to each other, The content is switched and displayed in synchronization with the display means of the other vehicle belonging to the vehicle .

In the invention according to claim 4 , since the contents displayed at the display stage of the group of moving bodies are switched in synchronization, the effect of displaying the contents can be enhanced.
When switching contents synchronously, the contents are basically switched simultaneously on each display means. For example, the display means arranged in the front-rear direction are delayed by a certain time from the previous display means. The contents may be switched. For example, if the content is switched one second later than the previous display means, the content displayed on the display means is switched one second at a time from the previous display means, so that new content is displayed from the front. A wave-like display appears toward the back.

The invention according to claim 5 uses the integrated display system according to any one of claims 1 to 4 when a plurality of vehicles provided with display means on the surface of the vehicle body are close to each other. An integrated display method for displaying content related to each other by a plurality of display means of the vehicle as an integrated display means group,

  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 moving objects 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 in this example displays contents related to each other as an integrated display means group when display panels Dsp as display means provided in vehicles as a plurality of moving objects are close to each other. Is to do. That is, the integrated display system is configured to display contents related to each other as an integrated display means group when the display means provided in each of the plurality of moving objects are close to each other.
In the integrated display system, a plurality of taxis (vehicles as moving bodies) Tx1, Tx2,... Connected to the same radio repeater TRx repeat a set-discrete manner in a taxi pool in the station premises and public roads around the station. At the same time, when moving while repeatedly stopping and starting, the display panels Dsp are linked to each other to form an integrated display surface to display contents 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 databases 1 and servers 2 and 3 are installed in each taxi Tx1, Tx2,..., And a portable computer system such as an in-vehicle computer system such as a vehicle terminal with a wireless LAN function, a portable terminal (including a cellular phone, PHS, etc.). Any taxi Tx1, Tx2,... Can function as a moving body 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 non-volatile memory as a storage device) and a computer main body (an in-vehicle computer system, a portable computer system) provided with a CPU or the like. It is only necessary that various programs that function as the linkage analysis server 2 and the frame allocation server 3 can be executed.
Taxi Tx1, Tx2,... As the moving body in this example is a wireless communication that enables data communication such as the content database 1, the linkage analysis server 2, the in-vehicle computer system that functions as the frame assignment server 3, the wireless LAN described above Equipment. 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 the plurality of display panels Dsp provided in one moving body, and these images are included in one taxi Tx1, Tx2. Are stored in a state associated with the panel code corresponding to each display panel Dsp.

Further, the positions of the display panels Dsp provided in the taxis Tx1, Tx2,... Are, for example, side surfaces (doors and front and rear 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. In the case where there are a plurality of display panels Dsp in one moving body and different contents are displayed respectively, 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 mobile body as area data are provided. It is necessary to be mounted on. 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 a 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 absolute position is determined by the radio relay TRx with which the mobile body communicates. A region (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 moving body 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 relay TRx is communicating.
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 groups of the moving objects close to each other and the arrangement of the groups of the moving objects, and the moving objects in the array pattern. It functions as a content accumulating means for accumulating and storing in association with the relative positions.

  In addition, the above-described arrangement pattern includes an arrangement pattern of a single moving object in the vicinity of the moving object and no other moving object, and content is stored in the content database 1 corresponding to the single arrangement pattern. It is remembered. 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 moving body.

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 by arranging the frames of the two pieces of partial image information 13a and 13b in a line before and after in the traveling direction . 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 arrangement 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 the 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,. A plurality of taxis Tx1, Tx2,... That are close to each other are made into a group of moving bodies. In this case, the number of different vehicle IDs of Tx1, Tx2,.

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 ... 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 recognize the order of vehicles by determining the distance based on the strength of the reception level of the measurement radio wave from the same direction.

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 mobile object belongs, and specifies the relative position of the mobile object in the specified array pattern. .

  In addition, from the above, the cooperation analysis server 2 as the cooperation analysis means is provided for each mobile body and includes a wireless communication device 32 having a plurality of directional antennas 31 directed in different directions, and each mobile body. An in-vehicle computer system 33 as a relative position calculating means for calculating the distance and direction of the moving object that is close based on the radio intensity of the radio wave transmitted and received by each directional antenna of each moving object In-vehicle computer as an array pattern calculation means for obtaining the array pattern and the relative position in the array pattern by sharing data of the direction and distance of the mobile body existing around each mobile body between the mobile bodies And a system 33. 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 the arrangement pattern etc. centered on itself determined by the system 33 from the moving body side to the fixed station side, each movement is performed in the state where the data is shared as described above by the cooperation analysis server 7 provided in the fixed station. The arrangement pattern of the body and the relative position within the arrangement 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 arrangement pattern to which the mobile body specified by the cooperation analysis unit belongs and the relative position in the arrangement pattern, and extracts the content. Then, the frame allocation server 3 as the content allocation unit determines the content searched by the content determination unit based on the array pattern specified by the cooperation analysis unit of the mobile body and the relative position in the array pattern. It is displayed on the display means of the moving body.

  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, when the taxi Tx1, Tx2,... As the moving bodies move and the arrangement pattern to which the taxis Tx1, Tx2,... Belong and the relative position in the arrangement pattern change, the contents are switched and displayed. It will be displayed on the panel Dsp.

That is, the collaboration analysis server 2 as the collaboration analysis means changes the arrangement pattern to which the moving body belongs and the relative position in the arrangement pattern based on the change in the position of the taxis Tx1, Tx2,. The change is constantly monitored, and the array pattern and the relative position after the change of each moving body are output corresponding 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 in the arrangement pattern to which the moving body belongs and the relative position output from the cooperation analysis unit. It will be.
Further, the frame allocation server 3 serving as the content allocation unit allocates content corresponding to the change in the arrangement pattern to which each mobile object belongs and the relative position in the arrangement pattern based on the content output from the content determination unit. It is replaced and displayed on the display panel Dsp as 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. In other words, the frame allocation server 3 as the content allocation means is configured to be able to display a plurality of contents on the display panel Dsp as the display means by switching over time, and is synchronized with the display means of other nearby mobile objects. Thus, the contents are 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). The current position of the taxi may be determined by positioning with GPS (Global Positioning System), or simply, it is determined as the jurisdiction of the wireless network LAN by connecting to the narrow-area wireless network LAN. May be. 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, and this content is displayed on the display panel Dsp as a display means provided in the vehicle. 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 region (area data) to which the position of the moving body 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.

  In addition, although the taxi was mentioned as an example of the moving body of the present invention, it may be a bus as described above. In this case, in a station where many bus routes are concentrated, there are buses around the station. There is a possibility of running side by side or parked and parked, and an integrated display similar to that of a taxi can be performed.

Moreover, a racing car in a racetrack can be applied as the moving body of the present invention.
In car racing, formation laps and other formations are performed at the start, and if the yellow flag is shaken due to trouble during the race (in the case of yellow cautions), overtaking is prohibited, and this causes the racing car to form There is a possibility of running.
In particular, when a pace car enters the course when the yellow flag is swung, the pace car that cannot be overtaken travels at a low speed, so that the convoy travel state is surely achieved.

  Therefore, also in the racing car, by using the same integrated display system as in the case of the taxis Tx1, Tx2,. The integrated display system can have the same configuration except that the moving body is changed from a taxi Tx1, Tx2,.

That is, when the racing cars are close to each other, the content is displayed on the display panel Dsp installed in each racing car, as in the case of the taxis Tx1, Tx2,. In such a case, the contents in cooperation with each other are displayed on the display panels Dsp of these racing cars.
For example, when several racing cars travel side by side or tail to nose, information related to each other is displayed on each display panel Dsp of the racing cars traveling as a group. In the case of such a close battle, for example, when the content database 1 or the like is on the fixed station side, the contents indicating the rank are transmitted from the fixed station side, and the rank is added to the display panel Dsp of the racing car in addition to the contents. May be displayed to increase the race. When the content database 1 or the like is on the in-vehicle computer system side, data indicating the ranking may be transmitted from the fixed station side, and the content may be selected based on this ranking.

  The content database 1 stores content in association with the arrangement pattern and relative position as described above, but the content stored in association with the arrangement pattern and relative position includes content corresponding to a plurality of ranks. The content may be selected according to the arrangement pattern, the relative position, and the order so as to be included.

In addition, when a racing car is running in a row with the above formation lap or yellow caution, for example, the content switching timing is the same as described above, or a wave-like effect is produced by slightly shifting the time. By doing so, a high production effect can be obtained.
During formation laps and yellow cautions, the race is not started and the spectators are not focused on the race, and it is easy for the spectators to draw attention. When an advertisement is displayed as content on Dsp, an extremely high advertising effect can be obtained.

Further, the moving body of the present invention is not limited to a vehicle or a transportation means, and includes, for example, a device that is attached to a sports player, a horse racing horse, a jockey, etc. and moves together with the sports player or the horse. It is. In this case, the device includes a small computer system such as a so-called wearable computer, a position measuring means, a wireless communication device, and a display panel Dsp, which is equivalent to the device mounted on the taxis Tx1, Tx2,. It has the function of. Note that as the display panel Dsp, electronic paper that can be formed into a sheet-like flexible configuration (a configuration like paper) is suitable.
In athletics, horse racing, and the like, integrated display similar to the above-described racing car (excluding formation laps, yellow cautions, etc.) can be performed.
In addition, as a position measurement means necessary for the analysis of the arrangement pattern, a portable GPS or a wireless communication device having the above-described directional antenna can be used. Part. Furthermore, in ball games such as American football, a television camera is set so that the stadium can be photographed planarly from a place above the stadium, so that an image captured by the television camera is subjected to known image recognition. Thus, it is possible to recognize the arrangement and relative position of each player (a device that is a moving body of the present invention attached to the player). By recognizing images taken by a TV camera that takes a two-dimensional image of the stadium to determine the player's arrangement pattern and relative position, it is easy to distinguish between players on the stadium and players on the bench side. Identification becomes possible.

Further, for example, in the case of American football, the game is started from a state in which various offenses (defenses) are formed according to the situation of the offense and defense at each time of down.
Therefore, it is preferable to display contents that cooperate with each other on the display panel Dsp that is attached to each player when forming the formation. For example, the product name, company name, brand name, etc. of the advertiser are displayed on the display panels of a plurality of players.

  In addition, there are many types of formation on the offense side, and there are cases where the name of the formation varies depending on the team. Therefore, as a unified display to be linked, a plurality of characters that form the formation name are displayed on a plurality of display panels Dsp. It may be displayed across (separately), so that the audience can understand the names of the formations and enjoy the game more. In this case, it is preferable to display the advertiser name and mark together with the formation name.

  In the in-vehicle or fixed station computer system having the functions as the above-described content database 1, cooperation analysis server 2, and frame allocation server 3, processing is performed by an input program. For example, the computer system In order to perform the above-described processing, a plurality of arrays indicating the number of groups of the moving bodies adjacent to each other and the arrangement of the groups of the moving bodies are displayed on the display unit based on a program A step of classifying and storing each pattern relative to the relative position of the moving body within the array pattern, and the array pattern to which the moving body belongs based on the position of each moving body measured and input by the position measuring means And specify the relative position of the moving body in the specified array pattern. And the step of searching the stored and stored content based on the specified array pattern and the relative position in the array pattern to extract the corresponding content, and the mobile object belongs to the extracted content Based on the array pattern and the relative position in the array pattern, a step of displaying on the display means of the moving body is executed. Further, the above-described processing performed by the computer system in the above example is executed based on a program.
