  FIG. 1 is a block diagram showing a configuration example of a map data information sharing / updating system according to an embodiment of the present invention.

  As shown in FIG. 1, the map data information sharing / updating system according to the present embodiment includes, for example, portable terminals (for example, mobile phones) 11 and 41 corresponding to the map data information sharing / updating system, and a host such as a server. The apparatus 21 includes a communication network 31 such as the Internet network, and a home terminal 51 such as a personal computer (PC).

  The mobile terminal 11 receives a control unit 12 that controls the operation of the mobile terminal 11, a wireless unit 13 that is connected to a communication network, information (a database to be described later, a control program for the control unit 12, and a host device 21. Memory 14 that stores and holds information, etc., and functions as a work area of the control unit 12, a display unit 15 that displays images and information transmitted to the user of the portable terminal 11, and the terminal 11 And an operation unit 16 that receives an input operation by a user. The mobile terminal 41 is configured in the same manner as the mobile terminal 11.

  The mobile terminals 11 and 41 download the map data information by downloading a program for using the map data information sharing / updating system and a terminal database (see FIG. 5), which will be described later, based on a predetermined contract. It may correspond to a sharing / updating system. Alternatively, the mobile terminals 11 and 41 may be sold in a state in which the programs and the terminal database are stored in advance as compatible models of the map data information sharing / updating system.

  The host device 21 includes a control unit 22 that controls the operation of the host device 21, a connection unit 23 that connects to a communication network, a storage 24 that stores a database (host database) such as map information, and an administrator 21, an operation unit 25 for operating 21, a display unit 26 for displaying various data, and information (a database, a control program for the control unit 22, and information received from the mobile terminals 11 and 41 and the home terminal 51. Etc.) and a memory 27 that functions as a work area of the control unit 22.

  Although not shown, the home terminal 51 includes a control unit that controls its operation, a memory that stores and holds information, an operation unit that accepts user operations, and a display unit that performs display operations. For example, the home terminal 51 downloads a program for using the map data information sharing / updating system and a terminal database (see FIG. 5), which will be described later, based on a predetermined contract, thereby sharing the map data information. It corresponds to the system.

  The home terminal 51, the mobile terminals 11 and 41, and the host device 21 can communicate with each other via the communication network 31.

  Next, an example of a control method for acquiring and displaying map information on the mobile terminal 11 in the map data information sharing / updating system of FIG. 1 will be described with reference to FIGS. 2, 3 and 6.

  First, FIG. 2 is a flowchart showing a processing procedure executed before obtaining map information on the portable terminal 11 side.

  As shown in FIG. 2, the user of the mobile terminal 11, when acquiring map information, information about a place to be displayed (which map information is to be acquired and displayed) (hereinafter referred to as a display place) and a map scale ( (Map scale) is input (steps A102 and A103).

  Next, the user selects and inputs a type to be displayed on the map (step A104). Here, as the type, individual genres such as “bookstore” and “coffee shop” can be specified, and only necessary types of information can be acquired. A plurality of types can be selected at a time.

  In the subsequent step A105, an operation for transmitting the input display location, map scale, type, and the size (size) of the map displayed on the display unit 15 to the host device 21 is performed. In response to this operation, the control unit 12 transmits these pieces of information to the host device 21 through the wireless unit 13. Thus, the processing on the portable terminal 11 side before the acquisition of the map information is finished, and the control in the host device 21 is taken over.

  FIG. 3 is a flowchart showing a control flow executed by the host device 21 after the processing of FIG.

  Here, as shown in FIG. 4, the main database included in the host database stored in the storage 24 of the host device 21 includes a location database, a map database, and a shared object database.

  Of these, the location database stores the location name and location data consisting of latitude and longitude in association with each location on the map (for example, address, station, etc.). The location database B,... Corresponding to the location database A, B is configured.

  The map database stores map data (drawings) divided for each area and each map data area (maximum latitude, minimum latitude, maximum longitude, and minimum longitude) in association with each other. Map data A, map data B,...

  The shared object database is a database configured by collecting information on objects on the map (for example, stores and stations) for each object.

  That is, the shared object database is configured by a collection of data for each object (shared object data A related to the object A, shared object data B related to the object B,...).

  Each shared object data includes the type indicating the genre of each object such as “bookstore” and “coffee shop”, the name of each object (proprietary noun) such as “store name” and “station name”, and the location of each object. Position data of latitude / longitude, information data including numerical data selection information such as three-level evaluation such as “satisfaction 1: high 2: normal 3: low” and memo information that summarizes comments for each object, The number of registrations indicating the number of registrations by the user and the number of deletion requests indicating the number of times the user has requested deletion of each object are included.

  In the process of FIG. 3, first, in step A202, the data transmitted from the portable terminal 11 in step A105 of FIG. 2 is received.

  In the subsequent step A203, it is determined whether the received display location data is latitude / longitude data or location name (character data).

  In the case of character data, a place is searched from the place database included in the host database stored in the storage 24, and converted into corresponding latitude / longitude position data (numerical value) (step A204).

  Subsequent to step A204, or when the data of the display location is latitude / longitude data in step A203, the map scale of the received data and the size to be displayed on the screen are subsequent to step A203. The area of the map is calculated based on the position of the received display location (latitude / longitude range maximum latitude: LATmax, minimum latitude: LATmin, maximum longitude: LNGmax, and minimum longitude: LNGmin). Is calculated (step A205).

  Subsequently, using the calculated display area data, map data including the display area is extracted from the map database of the host database (step A206), and only the display area portion is cut out from the extracted map data (step A207).

  Subsequently, a shared object having position data in the display area is extracted from the shared object database (step A208), and the type of shared object received from the extracted shared object is extracted (step A209).

  Next, with respect to the extracted shared object, only those whose registration count is larger than the registration reference value (for example, 20) are extracted (step A210).

  Subsequently, the map data (drawing) of the display area cut out in the previous step A207 and the display area calculated in the previous step A205 (latitude / longitude range maximum latitude: LATmax, minimum latitude: LATmin, maximum longitude) : LNGmax, minimum longitude: LNGmin) is transmitted to the portable terminal 11 (step A211), and further, the shared object data extracted in the previous step A210 is transmitted to the portable terminal 11 (step A212). Of the shared object data, what is transmitted to the mobile terminal 11 is the remaining data (type, name, position data, information data) from which the number of registrations and the number of deletion requests are deleted.

  Here, the configuration of the terminal database stored and held in each of the mobile terminals 11 and 41 and the home terminal 51 is shown in FIG.

  As shown in FIG. 5, the main database included in the terminal database is an icon database (shared icon database, integrated icon database, and registered icon database) that stores icons (display data) displayed on a map for each type of object. ), An information format database that is a database in a format for displaying information according to various types, a registered object database that is a database of registered objects, and a deleted object database that is a database of deleted objects. ing. Of these, the registered object data includes type, name, position data, and information data, and the deleted object data includes type, name, and position data.

  Next, FIG. 6 is a flowchart showing a control flow in the portable terminal 11 after obtaining the map information.

  First, the portable terminal 11 receives the display area and map data (drawings) transmitted from the host device 21 in steps A211 and A212 in FIG. 4 and the shared object data in steps A302 and A303. To remember.

  Subsequently, in steps A304 and A305, a deleted object having the position data in the display area and the type selected in the previous step A104 is extracted from the deleted object database.

  In the following step A306, it is determined whether or not the deleted object is extracted in the previous step A305. If it is extracted (YES in step A306), the process proceeds to step A307.

  In step A307, the received shared objects include (1) the same type as the extracted deleted object, (2) the same name as the extracted deleted object, and (3) the extracted deleted object and position data. It is determined whether or not there is an object that satisfies the three conditions of being close to each other. Here, when the absolute value of the difference between the position data (latitude and longitude) between the objects is below the reference value, it is determined that the position data is close.

  If it is determined in step A307 that an object satisfying the condition exists (YES in step A307), the shared object and the deleted object are extracted, the extracted deleted object is excluded from the extraction candidates, and the extracted shared object is carried by the mobile phone. Delete from the memory 14 of the terminal 11 (step A308).

  Further, following step A308, the processing from step A306 is repeated. For this reason, step A308 is repeated until there is no object that satisfies the condition in step A307. Therefore, all the deleted objects that satisfy the condition of step A307 are excluded from the extraction candidates, and all the shared objects that satisfy the condition are included in the mobile terminal. 11 memory 14 is deleted.

  On the other hand, if there is no object that satisfies the condition in step A307 (NO in step A307), the process proceeds to step A309.

  In step A309, the extracted deleted object is deleted from the terminal database, and the process proceeds to step A310.

  Further, when the deleted object is not extracted (NO in step A306), the process proceeds to step A310.

  In step A310, a registered object having position data in the display area is extracted from the registered object database. In subsequent step A311, a registered object having the type selected in the previous step A104 is extracted from the extracted registered objects. .

  In the subsequent step A312, it is determined whether or not the registered object is extracted in the previous step A311. If it is extracted (YES in step A312), the process proceeds to step A313, and (1) An object that satisfies the following three conditions: the same type as the extracted registered object, (2) the same name as the extracted registered object, and (3) the extracted registered object and position data are close to each other. Determine if it exists.

  If there is an object that satisfies the condition (YES in step A313), the combination of the registered object and the shared object is extracted and integrated as one set (integrated object), and the integrated registered object and shared object are excluded from the extraction candidates. (Step A314).

  Subsequently, an icon (integrated icon) corresponding to the type of the integrated object is acquired from the integrated icon database (step A315), and the received icon is displayed according to the position data (latitude, longitude) of the registered object before the integration. Plot on the map data of the area (step A316).

  Further, following step A316, the processing from step A312 onward is repeated. Therefore, steps A314 to A316 are repeated until there is no object that satisfies the condition in step A313.

  On the other hand, if there is no object that satisfies the condition in step A313 (NO in step A313), an icon corresponding to the type of the registered object is acquired from the registered icon database (step A317), and the registered icon is obtained according to the position data. Then, it is plotted on the map data in the display area (step A318). That is, the processes of steps A317 and A318 are performed on objects other than those integrated.

  After step A318, the process proceeds to step A319.

  If no registered object is extracted (NO in step A312), the process proceeds to step A319.

  In step A319, an icon (shared icon) corresponding to each shared object type is acquired from the shared icon database (step A319), and the shared icon is plotted on the map data in the display area according to the position data (step A320). . The received map data of the display area and the plotted icon are displayed on the display unit 15 of the mobile terminal 11 (step A321).

  Here, display examples of map data on the display unit 15 are shown in FIGS.

  First, FIG. 7 is the map data of the display area received in step A302.

  As a result of plotting the icon of each object on the map data according to the position data, the screen display of FIG. 8 is obtained.

  In the example shown in FIG. 8, three types of “bookstore”, “cafe”, and “station” are displayed as objects. In addition, the display is different for each type and can be easily understood (for example, a display that simulates a book for a bookstore, a display that simulates a cup for a coffee shop, and a display that simulates a train).

  Further, each object is distinguished as a registration icon with a star flag, a unified icon with an unmarked flag, and a shared icon with no flag.

  Next, FIG. 9 shows a display when the cursor is moved in FIG. 8 and an icon is selected.

  For example, when a bookstore which is a registration icon is selected, as shown in FIG. 10, the format to be displayed in that type is acquired from the information format database, and the type, name, and information data of the registered object (for example, the number of assortments, The level of satisfaction and the memo information (for example, “there are many books!” As shown in FIG. 10) are displayed according to the format. In the example shown in FIG. 10, in order to indicate that the object is a registered object, an asterisk is displayed in the upper right column in the format.

  Further, when a coffee shop that is a shared object is selected, similarly, as shown in FIG. 11, the format to be displayed for that type is acquired from the information format database, and the type, name, and information data of the shared object (for example, in the store) Size, taste of food, level of satisfaction, and memo information (for example, as shown in FIG. 11, “The store is a little narrow. ) Is displayed according to the format. In the example shown in FIG. 11, the upper right column in the format is left blank to indicate that it is a shared object.

  Further, when the coffee shop which is an integrated icon is selected, as shown in FIG. 12, the format in the case of the registered object and the format in the case of the shared object are displayed in an overlapped manner. Switch the display.

  Next, an example of a control method for registering an object in map data will be described with reference to FIGS.

  Among these, FIG. 13 is a flowchart showing a processing procedure performed on the terminal (for example, portable terminal 11) side in the process of registering an object.

  First, the mobile terminal 11 does not yet have a registered shared object. Therefore, whether the mobile terminal 11 is a new registration or a shared object that has already been registered and is additionally registered. Determine (step C102).

  If it does not exist (in the case of new registration), the user designates the position where the object is registered on the map and selects “Register” (step C103).

  In subsequent step C104, the portable terminal 11 converts the designated position into latitude / longitude and registers the position in the new registration object data.

  Next, the user selects a type to be registered and registers the type (step C105).

  Next, the portable terminal 11 acquires the format of the type from the information format database, and displays a format with an empty name and information (step C106).

  Next, in accordance with the format, the user enters a name in the name column (step C307), selects information on the selection formula, and enters memo information in the memo column (step C108).

  Next, when the user selects “complete”, the portable terminal 11 registers the entered or selected name and information data (selection information, memo information) in the registration object data (step C109).

  Next, the mobile terminal 11 acquires an icon (registered icon) corresponding to the type of the newly created registered object from the registered icon database (step C110), and plots the registered icon on the map data according to the position data. And display (step C111).

  On the other hand, when there is a shared object that has already been registered, and the registered object is additionally registered in the sense of adding its own information to the shared object, the user selects the target shared object (shared icon) on the map. In response to the selection (step C112), the portable terminal 11 displays the shared object (step C113).

  Subsequently, the user selects “Register” and registers the type, name, and position data of the shared object in the new registered object data (step C114).

  Subsequently, the information data of the displayed shared object is deleted (step C115), selection information is selected according to the format, and memo information is entered in the memo column (step C116).

  Next, when the user selects “complete”, the portable terminal 11 registers the selected or entered information data (selection information, memo information) in the registered object data (step C117).

  Subsequently, the mobile terminal 11 integrates the newly created registered object with the shared object to be added (step C118), and acquires an icon corresponding to the type of the integrated object from the integrated icon database (step C119).

  Subsequently, the shared icon on the addition target map is changed to the acquired integrated icon (step C120).

  In C121 following Step C120 or the previous Step C111, the newly created registration object is transmitted to the host device 21, and the registration control in the portable terminal 11 is completed.

  FIG. 14 is a flowchart showing a control flow executed by the host device 21 after the processing of FIG.

  First, in step C202, the registration object transmitted in step C121 of FIG. 13 is received.

  In the subsequent step C203, the shared object includes (1) the same type as the received registered object, (2) the same name as the received registered object, and (3) the received registered object and position data. It is determined whether there is an object that satisfies the three conditions of being close.

  If it is determined in step C203 that there is an object that satisfies the condition (YES in step C203), the shared object is extracted (step C204).

  Subsequently, using the extracted position data of the shared object, the received position data of the registered object, and the number of registrations of the shared object, an average value of the position data of the object is calculated, and the calculated position data is extracted. Re-register as shared object position data (step C205).

  Here, as an average value calculation method, for example, if the shared object position data is A, the registered object position data is B, the shared object registration number is C, and the calculated average value is D, D = ( The average value D can be obtained from A × C + B) / (C + 1).

  Similarly, an average value is calculated also in numerical data of evaluation of selection information of information data, and each calculated selection information is re-registered in the extracted shared object (step C206).

  Next, in the memo information of the information data, the memo information of the registered object is added to the extracted memo information of the shared object and re-registered (step C207).

  Then, the registration count of the extracted shared object is increased by “+1” (step C208).

  On the other hand, if the corresponding shared object does not exist in step C203 (NO in step C203), the type, name, position data, and information data of the received registered object are registered in the new shared object data (step C209). .

  Then, the registration count of the newly created shared object is set to “1” (step C210).

  In the above, the reflection of the registered object data to the shared object data is completed (C211), and the object registration process ends.

  Next, an example of a control method for deleting an object in map data will be described with reference to FIGS. 15 and 16.

  Among these, FIG. 15 is a flowchart showing a processing procedure performed on the terminal (for example, portable terminal 11) side in the process of deleting an object.

  First, the user performs an operation of selecting “delete” (step D101).

  Subsequently, the user selects an icon (object) on the map to be deleted (step D102).

  Then, the mobile terminal 11 determines whether the selected icon is a registered icon, an integrated icon, or a shared icon (Step D103).

  If it is determined that the registration icon has been selected, the type, name, and position data of the selected registered object data are registered in the new deleted object data (step D104).

  Subsequently, while deleting the selected registered object and the registered icon from the screen (step D105), the selected registered object is deleted from the registered object database in the terminal (step D106).

  If it is determined in step D103 that the integrated icon has been selected, the type, name, and position data of the shared object data among the selected registered objects and shared objects are registered in the new deleted object data (step D108).

  Subsequently, the selected registered object, shared object, and integrated icon are deleted from the screen (step D109), the selected registered object is deleted from the registered object database in the terminal (step D110), and the selected shared object is stored in the memory 14. Delete from above (step D111).

  If it is determined in step D103 that the shared icon has been selected, the type, name, and position data of the selected shared object data are registered in the new deleted object data (step D113).

  Subsequently, while deleting the selected shared object and the shared icon from the screen (step D114), the selected shared object is deleted from the memory 14 (step D111).

  After the deletion of each object is completed (following step D111 or step D106), the newly created deletion object is transmitted to the host device 21 (step D115), and the deletion process in the portable terminal is completed.

  FIG. 16 is a flowchart showing a control flow executed by the host device 21 after the processing of FIG.

  First, in step D202, the deleted object transmitted in step D115 of FIG. 15 is received.

  In the subsequent step D203, the shared object includes (1) the same type as the received deleted object, (2) the same name as the received deleted object, and (3) the received deleted object and position data. It is determined whether there is an object that satisfies the three conditions of being close.

  If it is determined in step D203 that it does not exist (NO in step D203), the process in FIG. 16 ends.

  If it is determined in step D203 that it exists (YES in step D203), the shared object is extracted (step D204).

  Subsequently, the number of requests to delete the extracted shared object is increased by “+1” (step D205).

  Subsequently, it is determined whether or not the number of deletion requests exceeds a deletion reference value (example: 10) (step D206).

  If it is determined in step D206 that it has exceeded (YES in step D206), the extracted shared object is deleted from the shared object database of the host device 21 (step D207).

  On the other hand, if it is determined in step D206 that it has not exceeded (NO in step D206), the processing in FIG. 16 ends.

  This completes the object deletion process.

  In addition, in the above, the process performed with the portable terminal 11 can be similarly performed with the portable terminal 41 or the home terminal 51.

  According to the embodiment as described above, the host device 21 that supplies the map information via the communication network is provided, and the host device 21 includes a map information database (map database) that stores a plurality of map information (map data), and An object database (shared object database) that stores object data including related information related to each object and position information of the object, and corresponds to the map information when providing the map information In a system in which the object data located on the map is also provided to a user terminal (mobile terminal 11, 41, home terminal 51, etc.), the reliability of the object data is determined as the number of registration requests for the object data. And reliability based on at least one of delete request count Only the object data for which reliability is determined to exceed the reference value by the determination means (configured by the control unit 22) and the reliability determination means are shared among the users, and are transferred from the host device 21 to each user terminal. Since the shared information selecting means (configured by the control unit 22) that can be provided is provided, the reliability of the shared object data can be improved.

  Also, on the host device 21 side, the registered data is checked for identity in the type, name, and position data, the same data is merged into one object, and the number of registrations is counted. When this number of registrations exceeds the reference value, it is distributed to the user for the first time and is in a shared state. Similarly, the deletion is deleted from the database of the host device 21 when the number of requests for deletion of the same data exceeds a reference value. By sharing only data that is equal to or higher than the reference value, it is possible to share only information that is reliable.

  The information displayed on the map can be arbitrarily registered and deleted by the user. The registration and deletion information applies a common format and is stored not only in the user's portable terminal but also in the host device, so that information can be shared with an unspecified number of users.

  Furthermore, it is possible to increase the amount of information in the map data by plotting icons on the map data and selecting each icon to display each information. Furthermore, it becomes possible to display only necessary information by selecting and narrowing down information to be displayed on the map. In addition, by converting the main information on the map into icons, the map drawing can be simplified and the map data can be easily updated.

  In addition, the user's own registration / deletion information is retained. Of the shared data in the display area, the data that matches the deletion data is deleted, and the registration data is added to the screen and output to the individual user. It is possible to display in a suitable form.

  In the above-described embodiment, the case where a place name is input or a point on the map is specified in the input of the display place or the registration of the place is exemplified. You may make it utilize as a positional data of a place and a registration place.

  As narrowing down of information to be acquired, narrowing down by type such as “bookstore” or “coffee shop” is given in the present invention, but further narrowing down by selection information of information data included in object data is possible, and the evaluation exceeds a certain level. It is also possible to acquire only a thing (for example, numerical data of evaluation of selection information is 2.5 or more). Further, the data can be narrowed down not only at the time of acquisition but also at the time of data display by inputting narrowed-down information after acquisition.

  The user terminal is not limited to the portable terminals 11 and 41 and the home terminal 51, and may be a car navigation system in which a wireless device is incorporated, for example.

  Furthermore, in the above description, only the object data whose registration request count (registration request count) from the user is larger than the registration reference value can be shared and provided to the user, while the deletion request count (deletion request count) from the user. In this example, the object data is deleted from the shared object, i.e., the reliability of the object data is determined based on the number of registration requests (registration count) and the number of deletion requests (deletion request count) for the object data, An example has been described in which only object data for which reliability is determined to exceed the reference value by the determination can be shared among the users and provided from the host device 21 to the terminal of each user. For example, the number of registration requests from the user (the number of registration requests) is reflected from the registration reference value. Only the large object data can be shared and provided to the user, and the shared data may not be deleted. In this case, the level of reliability can be improved as compared with the conventional case. Is possible. Or, conversely, the request from the user is reflected only by deleting object data whose delete request count (the number of delete requests) from the user is larger than the deletion reference value from the shared object. Only the administrator of the apparatus 21 may perform the process, and in this case as well, it is possible to improve the level of reliability as compared with the prior art.

  Further, in the above description, an example in which object data can be registered and deleted by a terminal (mobile terminals 11 and 41 or home terminal 51) has been described. However, only registration or deletion is possible. It may be.
