Description

The present invention relates to a server capable of communicating with a mobile terminal such as a mobile phone, a map distribution system including the mobile terminal and the server, and a program executed by a computer including a storage device.

In recent years, mobile phones equipped with a global positioning system (GPS) receiver have become widespread.
By using a mobile phone equipped with a GPS receiver, the user can grasp the current location from a screen display or the like. Further, by transmitting the position information received by the GPS receiver by e-mail or the like, the user can easily convey the position where the user is located to others.

By the way, an information processing system that uses a portable terminal for orienteering and a treasure hunt game is known (see Patent Document 1). In the information processing system of Patent Document 1, a data management device is installed beside an exhibit such as a museum or an exhibition hall. And when a participant approaches an exhibit, a data management apparatus transmits a management apparatus identifier with respect to the portable terminal which a participant has. When the mobile terminal receives the management device identifier, it is stored in the mobile terminal that the participant has reached the vicinity of the exhibit. When the mobile terminal transmits the management device identifier data received from the data management device to the center device at the end of the game, the center device determines that the received management device identifier data is a predetermined condition (for example, management of all data management devices). It is determined whether or not the device identifier has been received, and the determination result is output.

The data corresponding to the identification information may be other data that does not overlap with the other mobile phone 300. A specific example of the data corresponding to the identification information is a telephone number, for example.

The mobile phone 300 acquires position information data by a built-in GPS receiver 308 (not shown). In the present embodiment, the position information data is data indicating the location of the mobile phone 300 by latitude and longitude. Then, the mobile phone 300 transmits the received position information data to the server 200 together with an ID number assigned uniquely to the mobile phone 300. Further, the cellular phone 300 receives the display map image data from the server 200 and displays the display map image indicated by the display map image data on the liquid crystal panel 306 (not shown). Here, the display map image data received from the server 200 is generated by the image processing described above.

As described above, the movement history of the mobile phone 300 is stored in the server 200 as movement history data by transmitting and receiving data between the server 200 and the mobile phone 300. Then, when the server 200 generates display map image data reflecting the movement history data and transmits it to the mobile phone 300, the mobile phone 300 can display the display map image.

FIG. 2 is a diagram schematically showing an example of a screen displayed on the liquid crystal panel of the mobile phone shown in FIG.
On the liquid crystal panel 306, a map image around the location of the mobile phone 300 is displayed. The index 24 indicates the current location of the mobile phone 300.
The map image displayed on the liquid crystal panel 306 is divided by the boundary line 23 into two areas, a specific area 21 located in the upper left part of the liquid crystal panel and a normal area 22 excluding the specific area 21. The specific area 21 is displayed in color, while the normal area 22 is displayed in gray scale. In the drawing, the specific area 21 is indicated by a thick line, and the normal area 22 is indicated by a thin line.

The map image displayed on the liquid crystal display panel 306 is displayed based on the display map image data generated by the server 200 and transmitted to the mobile phone 300. The display map image data has a predetermined size centered on the location of the mobile phone 300 from map image data stored in a ROM 202 (not shown) as map image data storage means provided in the server 200. It is generated by being extracted and further subjected to image processing to be described later.

FIG. 3 is a diagram schematically showing a map image indicated by map image data stored in the server.
The server 200 stores map image data in a ROM 202 as map image data storage means. The map image 50 is an image indicated by the map image data. In the description of FIG. 3, it is assumed that the upper direction of the map indicates the north direction.
The straight line 30 is a straight line attached for convenience of description, and does not indicate the north end of the map image 50. Therefore, although not shown, the map image extends to the north side (upper side) of the straight line 30. The same applies to the straight line 40, and does not indicate the west end of the map image 50, and the map image extends to the west side (left side) of the straight line 40.

In the map image 50, a plurality of north-south division lines 31, 32, 33,... Extending in the east-west direction are arranged at equal intervals in the north-south direction. It is divided into equal parts. Each section is identified by symbols “A”, “B”, “C”,...

Moreover, the map image 50 has a plurality of east and west division lines 41, 42, 43,... Extending in the north-south direction, arranged at equal intervals in the east-west direction. Divided equally in the direction. Each section is identified by reference numerals “1”, “2”, “3”,...

When one area surrounded by the north-south lane line and the east-west lane line is referred to as a setting area, each setting area is identified by a combination of the above two types of codes (hereinafter also referred to as coordinates). For example, the coordinates of the setting area surrounded by the two-dot chain lines 32, 33, 41, and 42 are “C2”. In addition, about the north-south division line and the east-west division line, although shown with the dashed-two dotted line in the figure for convenience of explanation, it does not necessarily need to be set so that it can be visually recognized in the map image 50.

In the present embodiment, the map image data includes three types of data: image data indicating topography, buildings, etc., position information data represented by latitude and longitude, and information on the set area. The data indicating the same position are associated with each other.
Thereby, when the server 200 receives the position information data from the mobile phone 300, the CPU 201 can determine where the location of the mobile phone 300 is located on the map image indicated by the map image data. . Further, the CPU 201 can determine in which setting area the position is included. In the present invention, the data constituting the map image data is not limited to the example described above, and includes, for example, data indicating whether or not the location is a route (for example, a road, a track, etc.). It may be.

FIG. 4 is a diagram illustrating an example of movement history data.

The movement history data is associated with an ID number uniquely assigned to the mobile phone 300, and indicates the movement distance up to the present, data indicating whether or not the user has been in each setting area, and the mobile phone 300 The position information data received last time is stored. “◯” in the figure indicates that the user has been in the set area. “-” Indicates that the user has never been in the set area. For example, the movement history data shown in FIG. 4 indicates that the mobile phone 300 with the ID number 10001 has been located in the setting area A2, but has never been located in the setting areas A1 and J10.

When the server 200 receives the position information data from the mobile phone 300, the server 200 determines the location on the map image indicated by the map image data of the mobile phone 300 from the received position information data. Then, the setting area including the location is determined, and the fact that the mobile phone 300 has been located in the setting area is stored.

Server 200 compares the location of mobile phone 300 with the location at the time of the previous reception, and calculates the distance between the two points. The distance is calculated by comparing the coordinates of two points. Then, the calculated distance value is added to the movement distance value of the movement history data. Thus, the accumulated value of the moving distance of the mobile phone 300 so far is stored.
In the present embodiment, the case where the distance between the two points is calculated as a linear distance has been described. However, in the present invention, the method for calculating the distance between the two points is not limited to this method. When the image data includes data indicating whether or not the location corresponds to the route, the distance between the two points may be calculated along the route.

A GPS receiver 308 as position information acquisition means acquires position information represented by latitude and longitude based on a radio wave signal received from a GPS satellite (not shown).

FIG. 7 is a flowchart showing server-side processing performed in the server. This server-side process is executed when the CPU 201 as the position information receiving means receives the ID number and the position information data assigned to the mobile phone 300 from the mobile phone 300.
The CPU 201 included in the server 200 generates movement history data based on the position information data received from the mobile phone 300 (step S101). Here, the CPU 201 compares the received position information data with the position information stored in association with the map image data stored in the ROM 202 as the map image data storage unit, and displays the map image data indicated by the map image data. The location of the mobile phone 300 is determined. Then, the set area including the location is determined. Further, the CPU 201 compares the received position information data with the previously received position information data, and calculates the distance between the two points.

Next, the CPU 201 stores the movement history data generated in step S101 in the hard disk drive 205 as movement history storage means in association with the ID number described above (step S102). Remember that you have been in the set area. In addition, the distance value calculated in step S101 is added to the movement distance value of the movement history data and stored.

After finishing the process of step S102, the CPU 201 as the specific area setting unit performs a specific area setting process (step S103). The specific area setting process will be described in detail later with reference to FIG. Thereafter, the CPU 201 as the image processing unit performs image processing (step S104). The image processing will be described in detail later with reference to FIG.

After completing the process of step S104, the CPU 201 as the map image transmitting means transmits the display map image data generated by the image processing to the mobile phone 300 (step S105). Thereafter, the CPU 201 determines whether or not the movement history data stored in the hard disk drive 205 satisfies a specific condition (step S106). The content of the specific condition is not particularly limited. For example, the value of the moving distance is a certain value or more, and the number of set areas that have been located is a certain number or more. When it is determined that the specific condition is satisfied (step S106: YES), the CPU 201 as the transmission unit transmits data indicating that the specific condition described above is achieved to the mobile phone 300 (step S107). When it is determined that the specific condition is not satisfied (step S106: NO), and after the process of step S107 is finished, this subroutine is finished.

FIG. 8 is a flowchart showing the specific area setting process. The specific area setting process is called and executed in step S103 of the server side process shown in FIG. When executing the specific area setting process, the CPU 201 functions as a specific area setting unit.
First, the CPU 201 extracts map image data centered on the location of the mobile phone 300 indicated by the received position information data from the map image data stored in the ROM 202 (step S501). Here, the CPU 201 detects a position on the map image indicated by the map image data stored in the ROM 202 where the position information data matches the location of the mobile phone 300 indicated by latitude and longitude. Then, map image data indicating a map image of a predetermined size centered on the position indicating the location of the mobile phone 300 is extracted from the map image data stored in the ROM 202.

Next, the CPU 201 refers to the movement history data for all the setting areas included in the map image data extracted in step S501, and determines whether or not the mobile phone 300 has been located (step S502). For example, when the map image data extracted in step S501 includes four setting areas A2, A3, B2, and B3, the movement history stored in association with the ID number of the mobile phone 300 Of the data, the data for the four setting areas described above are referred to.

Next, the CPU 201 sets, as the specific area, the area included in the setting area where it is determined that the mobile phone 300 has been located in step S502 for the map image data extracted in step S501, and that the mobile phone 300 is located. An area included in the set area determined to be absent is set as a normal area (step S503). For example, if the CPU 201 determines that the mobile phone 300 has been located in A2, B2, and B3 among the four setting areas described above and has not been located in A3, the CPU 201 determines that the setting area A2, The area included in B2 and B3 is set as a specific area, and the area included in the setting area A3 is set as a normal area. After the processing of step S503 is finished, this subroutine is finished.

In the description of step S501, it has been described that the CPU 201 extracts map image data indicating a map image of a predetermined size from the map image data stored in the ROM 202, but the present invention is not limited to this. In the present embodiment, the scale of the map image displayed on the liquid crystal panel 306 of the mobile phone 300 is described as being constant and is displayed at the same scale as the map image data stored in the ROM 202. The scale of the map image displayed on the panel 306 may be changeable. In this case, data indicating the scale of the displayed map image is transmitted from the mobile phone 300 to the server 200. The CPU 201 that has received the data determines the size of the map image to be extracted based on the received data. Then, based on the received data, a process for enlarging or reducing the extracted map image is performed. Here, the size of the map image extracted in advance is determined so as to be the size displayed on the liquid crystal panel 306 when the image is enlarged or reduced.

Also, the map image indicated by the map image data stored in the ROM 202 is not enlarged or reduced, but map image data of a plurality of types of scales is stored in advance. The map image data matching the data indicating the scale of the received map image may be selected, and the map image data indicating the map image having a predetermined size may be extracted. Of course, the two methods described above may be used in combination.

FIG. 9 is a flowchart showing image processing. The image processing is called and executed in step S104 of the server side processing shown in FIG. When executing this image processing, the CPU 201 functions as an image processing means.
First, the CPU 201 performs a monochrome process so that the area set as the normal area in the specific area setting process described above is displayed in black and white gray scale (step S601). Thereby, the specific area and the normal area are visually identified. Since the technology for converting a color image into a monochrome image is well known from Japanese Patent Application Laid-Open No. 11-185017 and the like, description thereof is omitted here.

Next, the CPU 201 stores the image data that has been subjected to the monochrome process for the normal area in step S601 in the RAM 203 as display image data (step S602). The display image data is data that can be displayed on the liquid crystal panel 306 of the mobile phone 300 by being transmitted to the mobile phone 300. The information indicating the latitude / longitude and the set area is unnecessary information and is deleted from the display image data. After the process of step S602 is completed, this subroutine is terminated.

FIG. 10 is a flowchart showing the cellular phone side processing performed in the cellular phone. This process is a process performed in the mobile phone 300 when the process shown in FIG.
First, the microcomputer 322 included in the mobile phone 300 acquires position information data indicating coordinates of the location of the mobile phone 300 by the GPS receiver 308 as position information acquisition means (step S201). Next, the microcomputer 322 as position information transmission means transmits the ID number uniquely assigned to the mobile phone 300 and the position information data acquired in step S201 to the server 200 (step S202).

After finishing the process of step S202, the microcomputer 322 as a map image receiving means receives display map image data from the server 200 (step S203). The display map image data is image data generated by the server 200 in the image processing shown in FIG. Next, the microcomputer 322 displays the display map image indicated by the received display map image data on the liquid crystal panel 306 as the map image display means (step S204).

After completing the process of step S204, the microcomputer 322 determines whether or not data indicating that the movement history data has achieved the specific condition has been received from the server 200 (step S205). The data indicating that the specific condition has been achieved is data transmitted to the mobile phone 300 when the movement history data stored in the server 200 satisfies the specific condition in the server-side processing shown in FIG. Say. When the data is received (step S205: YES), the microcomputer 322 displays a message indicating that the specific condition included in the data is achieved on the liquid crystal panel 306 (step S206). When the above data has not been received (step S205: NO) and after the processing of step S206 is completed, this subroutine is terminated.

Note that the processing on the mobile phone side shown in FIG. 10 is based on the premise that the mobile phone 300 always displays the display map image while executing the program according to the present invention. In the present invention, the display mode of the display map image is not limited to the above mode. The display image may be displayed only when a predetermined operation is received. In this case, in the mobile phone side processing, the timing for performing the processing for displaying the display map image shown in step S204 is not after the display map image data is received. That is, the process of step S204 does not exist in the flowchart shown in FIG.

As described above, according to the map distribution system 1 according to the present embodiment, it is possible to create the movement history data in the server 200 or visually reflect the movement history data without preparing a special device or the like in advance. The displayed map image can be displayed on the mobile phone 300. In addition, by using the mobile phone 300 that can acquire and transmit position information, time restrictions are reduced. Furthermore, since there is no need to prepare a special device or the like in advance as described above, the restriction on the place to be executed is reduced.

The embodiment according to the present invention has been described above. The present embodiment relates to a map distribution system configured by a server 200 and a mobile phone 300. However, the embodiment of the present invention is not limited to this. Hereinafter, processing when the present invention is implemented only by the mobile phone 300 will be described. Since the mobile phone 300 has the same configuration as that of the above-described embodiment, description thereof is omitted here, and corresponding components are described with the same reference numerals.

FIG. 11 is a flowchart showing processing performed by a single mobile phone.
First, the microcomputer 322 included in the mobile phone 300 acquires position information data indicating the location of the mobile phone 300 by coordinates using the GPS receiver 308 (step S301). Next, the microcomputer 322 generates movement history data based on the position information data, and stores the movement history data in association with the ID number in the nonvolatile memory 320 as movement history storage means (step S302).

After finishing the process of step S302, the microcomputer 322 performs a specific area setting process (step S303). The specific area setting process is the process shown in FIG. 8 and has already been described, and thus the description thereof is omitted here. Thereafter, the microcomputer 322 performs image processing (step S304). Since the image processing is the processing shown in FIG. 9 and has already been described, description thereof is omitted here.

After finishing the process of step S304, the microcomputer 322 displays the display map image data generated by the image processing on the liquid crystal panel 306 (step S305). Thereafter, the microcomputer 322 determines whether or not the movement history data stored in the nonvolatile memory 320 satisfies a specific condition (step S306). The content of the specific condition is not particularly limited. For example, the value of the moving distance is a certain value or more, and the number of set areas that have been located is a certain number or more. If it is determined that the specific condition is satisfied (step S306: YES), the microcomputer 322 displays a message indicating that the specific condition is achieved on the liquid crystal panel 306 (step S307). When it is determined that the specific condition is not satisfied (step S306: NO), and after the process of step S307 is finished, this subroutine is finished.

Further, the contents of the movement history data are not limited to those shown in FIG. The movement history data shown in FIG. 4 is associated with the ID number of the mobile phone 300, and the mobile phone when the movement distance, the data indicating whether or not the user has been in the set area, and the previous position information are received. In the present invention, the movement history data may be data related to the history of the location of the mobile phone 300 generated based on the location information data acquired by the mobile phone 300. .

FIG. 12 is a diagram illustrating a different example of movement history data.
The server 200 stores movement history data in the hard disk drive 205 as movement history storage means. The movement history data is associated with an ID number uniquely assigned to the mobile phone 300, and the time when the location information is received from the mobile phone 300 and data indicating the location information in latitude and longitude are accumulated and stored. Has been. That is, each time the server 200 receives position information data from the mobile phone 300, the server 200 stores the received position information data in the hard disk drive 205 as movement history data.

By setting the contents of the movement history data as described above, the above-described embodiment describes the criteria for setting a specific area in the specific area setting process described above, the contents of the process performed by image processing, and the like. Different contents can be used. Thereby, it becomes possible to display a map image different from the embodiment described above.
