Description

  The present invention relates to a system and program for updating data for narrowing down information on a huge amount of stores, various facilities, institutions, etc. held by a navigation device.

  2. Description of the Related Art Conventionally, navigation devices have been searched for locations such as stores, various facilities, and institutions by inputting addresses. The point data possessed by the navigation device includes identification information of the point, the name of the point, an address code, an address name, a telephone number, and the like. The address code is assigned to each level above the capital letter, such as prefecture, city (district, county), town (village), etc., with the prefecture level, city (district, county) level, town (village) level It is possible to narrow down by. It is known to set points such as destinations and passing points by using such address codes (Patent Document 1).

Further, when the map data including the polygons indicating the boundaries of the administrative divisions on the map, the address names of the administrative divisions, and the POI (Point Of Interest) data indicating the points of stores, facilities, etc. are separately provided, the POI The data has an ID (identification information), name, coordinate information, etc., but does not have an address name, and the POI coordinate information is associated with a polygon made up of a set of coordinates and the address in each POI data. Names are proposed that use the address names of the corresponding polygons to reduce the burden of updating the POI database when there is a change in address names due to mergers of municipalities or mergers. (Patent Document 2).
JP 2006-153866 A JP2007-212836

Although Patent Document 1 discloses that addresses are narrowed down using an address code, there is no disclosure about reducing the burden of updating point data when there is a merger or absorption of municipalities.
In Patent Document 2, although the burden of changing the address name in the POI database when there is a municipal merger or absorption merger, etc., the address code on the map database side, address narrowing when the address name is updated is Because the new address code and the new address name acquired from the map database are used, at least the old address cannot be narrowed down.

The present invention is intended to solve the above-described problems, and it is intended to reduce the burden of updating POI information when there is a merger of cities, towns and villages, and to narrow down addresses by any new and old addresses. To do.
The present invention provides a system for updating address data of POI information, address data including an address code and an address name at least assigned to each administrative division, information storage means for storing POI information, Update data acquisition means for acquiring update data including an address ID, update target data selection means for selecting address data to be updated stored in the information storage means based on the acquired update data, and the selected update target Update means for updating the address data while leaving the old address data.
Further, the present invention provides a program for controlling a system for updating address data of POI information, a step of acquiring update data including an address ID to be updated, an address to be updated from an information storage unit based on the acquired update data The computer is caused to execute a step of selecting data and a step of updating the selected address data to be updated while leaving the old address data.

  Since the present invention uses the address data including the address ID of the serial number for each administrative division and the address data including the address name, the address data is updated so as to leave the old address code. It is possible to reduce the burden of renewal and narrow down the address by using new and old arbitrary addresses.

Embodiments of the present invention will be described below.
FIG. 1 is a block diagram illustrating an example of an address data update system for POI data according to the present embodiment. The navigation device 1 may be any type of navigation device such as an in-vehicle device or a portable device. In the case of the in-vehicle device, the navigation device 1 detects the current position of the vehicle and reaches the passing point or destination. It has various functions such as searching for routes and guiding it. However, the explanation of these functions is omitted here, and a huge amount indicating points such as stores, various facilities, and institutions held by the navigation device 1 Data update processing for narrowing down POI (Point Of Interest) data by address will be described.

  When the navigation device 1 acquires the update data 2 from the distribution center, media, etc. when there is a boundary change or address name change due to merger of cities, towns and villages, etc., the navigation device 1 stores it in the information storage device 20 by the control device 10 The address narrowing data 22 is updated when searching for the address of the POI data 21 that has been set. As shown in FIG. 2A, the POI data stored in the information storage device 20 has an enormous amount of data having a data structure including an ID (identification information) of a location such as a facility, a facility name, an address code, and address characters. It is the amount of data, and the address characters are notation and are not a search tool for address narrowing. The address narrowing data 22 is composed of an address ID consisting of a serial number assigned to each administrative division, an address code that can be narrowed down to the municipal level, and an address name up to the municipal level. Compared to POI data. The amount of data is about one millionth.

  The update data acquisition means 11 of the control device 10 updates the update data through a communication means, a storage medium, etc. from a distribution center or media, etc. when there is a boundary change of an administrative division or a change of address name due to a merger of municipalities. 2 is acquired. The update data has an address ID, an address code, an address name, or update boundary data that can be selected as an update target. As will be described later, the update data also has the original old address code and old address name before update in this embodiment. I try to make it. When the update data is acquired, the update target data selection unit 12 searches the address narrowing data 22 based on the address ID and address code described in the update data, and selects the update target address narrowing data group. When the update target address narrowing data group is selected, the update means 13 updates the address code, address name, administrative division boundary, etc. of the update target address narrowing data with the update data. At this time, the original old address code and the old address name before the update are left in the updated address narrowing data. Thus, by updating the selected address narrowing data without updating the address code of the POI data, it is possible to reduce the burden of updating the POI information. And even if there is a change in the boundary of administrative divisions or a change in address name due to a merger of municipalities using the search means 14 on the search screen of the display device 30, the new address code or the old address code is used. To narrow down the POI data.

Next, update of address narrowing data will be described taking various forms of merger of municipalities as examples. In the following, for convenience, the address ID is displayed as a three-digit number, and the address code is displayed as a one-digit number.
FIG. 3 shows an example in the case where the address characters are not changed in the simple absorption merger, and FIG. 4 shows the update of the address narrowing data in the case where the address characters are not changed in the simple absorption merger.
Fig. 3 (a) shows the state before the merger, where Horiga City (address code 4) is simply merged with the adjacent Haruna City (address code 3), and the area indicated by the broken line in Fig. 3 (b) is Haruna City. This is the case. As shown in FIG. 4B, the update data is content in which the address codes 3 and 4 are assigned to the address narrowing data whose address ID is 103. The update target data selection means 12 uses the address ID 103 of the update data and the address codes 3 and 4 as the update target data, the address IDs 103 and 104 and the search target address code shown in FIG. Select data of 3 and 4 respectively, and address names of Haruna City in XX Prefecture and Horikawa City in XX Prefecture, respectively. Based on the update data, the update means 13 updates the data to the address ID 103, the new search target address codes 3 and 4, and the address name Haruna City, XX Prefecture, as shown in FIG. 4C. The updated address narrowing data has a plurality of address codes, and by leaving the old address code, it is possible to narrow down the new address code 3, 4 or the old address code 3, the old address code 4.

FIG. 5 shows an example in the case where there is a change in address characters in the simple absorption merger, and FIG. 6 shows an update of address narrowing data in the case where there is a change in address characters in the simple absorption merger.
FIG. 5 (a) shows the state before the absorption merger, and Horikawa City (address code 4) is simply absorbed and merged with the adjacent Haruna City (address code 3), and the new address in the area indicated by the broken line in FIG. 5 (b). This is the case when the name is Suruga City. As shown in FIG. 6 (b), the update data is such that address codes 3 and 4 are assigned to the narrowed-down data with an address ID of 103, and the address name is changed to Suruga City, XX Prefecture. The update target data selection means 12 uses the update data address ID: 103 and the address codes 3 and 4 as update target data, the address IDs 103 and 104 shown in FIG. Select data of 3 and 4 respectively, and address names of Haruna City in XX Prefecture and Horikawa City in XX Prefecture, respectively. Based on the update data, the update unit 13 updates the data to the address ID 103, the new search target address codes 3 and 4, and the address name Suruga City, XX prefecture, as shown in FIG. 6C. The updated address narrowing data has a plurality of address codes, and by leaving the old address code, it is possible to narrow down the new address code 3, 4 or the old address code 3, the old address code 4.

FIG. 7 shows an example in the case of becoming a government-designated city, and FIG. 8 shows updating of address narrowing data in the case of a government-designated city.
FIG. 7A shows the state before the government-designated city, and FIG. 7B shows the case where the Haruna city (address code 3) is subdivided into 7 categories by the government-designated city. As shown in FIG. 8 (b), the update data has the content that the administrative division of the address ID: 103 is converted into a government-designated city and is subdivided into seven sections here. The update target data selection means 12 starts from the update data address ID: 103 as update target data, the address ID shown in FIG. 8A is 103, the search target address code is 3, and the address name is in Haruna City, XX Prefecture. Select data. The updating means 13 sets the flag “1” in the extension data of the address narrowing data whose address ID is 103 based on the update data (FIG. 8C), and as shown in FIG. The management numbers A, L,... Are assigned to each area of the number of wards 7 by the conversion, and the data of the contents to which the subdivision data (coordinate data) is assigned as the address code 3 is updated. With such segmentation data (polygon), Haruna City is divided into seven wards as shown in FIG. 7B. When address narrowing is performed, it is possible to narrow down to the areas of management numbers a, ro ... using extended data.

FIG. 9 shows an example in the case of division merge, and FIG. 10 shows the update of address narrowing data in the case of division merge.
FIG. 9A shows the state before the split merger, and a part of the adjacent Haruna City (address code 3) is split and merged with Horiga City (address code 4), and the area i shown by the broken line in FIG. Is Horikawa City. As shown in FIG. 10 (b), the update data has the content that the address codes 4 and 3 are assigned to the address narrowing data whose address ID is 104, and the data is subdivided by the subdivision data (polygon). The update target data selection means 12 includes the address ID 104 and the address codes 4 and 3 as update target data as shown in FIG. 10 (a), the address IDs 103 and 104 respectively, and the search target address codes 3 and 4 respectively. Select the data for the address names of Haruna City in XX Prefecture and Horikawa City in XX Prefecture. Based on the update data, the updating unit 13 sets the flag “1” in the extension data of the address narrowing data whose address ID is 104 (FIG. 10C), and divides as shown in FIG. 10D. The management number a is assigned to the area, and the data of the content to which the subdivision data (coordinate data) is assigned as the address code 4 is updated. When address narrowing is performed with this update data, it is possible to narrow down to the area of management number a.

FIG. 11 is a diagram for explaining an address character string to be displayed as POI facility information.
Assuming that the update data for assigning the address codes 3 and 4 to the address ID: 103 as shown in FIG. 11B is acquired, the update target data selection means 12 uses the address ID: 103 and the address codes 3 and 4 as the addresses. As shown in FIG. 11 (c), the IDs are 103 and 104, the search target address codes are 3 and 4, respectively, and the address names are respectively the data of Haruna City in XX Prefecture and Horikawa City in XX Prefecture. Assume that you have made a simple update. That is, it is assumed that the new address code of the address ID: 103 is 3, 4 and the address name is Haruna City, XX Prefecture, the new address code of the address ID: 104 is 4, and the address name is Horiga City, XX Prefecture. Then, see the display information of Horikawa Park (address code 4, address letters are 1-chome, 1-chome) and Haruna Police Station (address code 3, address letters are 2-chome, 2-chome) shown in FIG. Since the address code 3 does not have duplicate address narrowing data (only the address ID: 103), the updated display information of the Haruna Police Station is simply a display in which the address name and address characters are concatenated, Since the address code 4 has duplicate address narrowing data (address IDs: 103 and 104), the updated display information of Horikawa Park concatenates a single designated address ID: 104 and address characters, and It is assumed that (old) indicating the possibility of the old address character string is given (FIG. 11 (e)).

FIG. 12 is an explanatory diagram when narrowing down is performed using the old address, and FIG. 13 is a diagram illustrating a narrowing screen.
FIG. 12A shows address narrowing data before update, FIG. 12B shows update data, and FIG. 13 shows address narrowing data after update. The update data is the content of assigning the address codes 3 and 4 to the address ID: 103, and the updated address narrowing data is the new address code of the address ID: 103 is 3, 4 and the address name is Haruna City, XX Prefecture. The old address ID: 103, the old address code 3, the old address name Haruna City, XX prefecture, and the old address ID: 104, the old address code 4, and the old address name XX prefecture, Horikawa City are added. In the case of such update data, the address narrowing screen is displayed as Haruna City (address ID: 103) and Horikawa City (address ID: 104) as the entire XX prefecture, as shown in FIG. Then, when Haruna City is selected, it is detected from the updated data that the old address ID: 103 exists, the user is inquired whether or not to narrow down by the old address, and it is selected to narrow down by the new address In this case, the address codes 3 and 4 are targeted for narrowing down, and if narrowing down by the old address is selected, only the address code 3 is targeted for narrowing down. When Horikawa City (address ID: 104) is selected, the address ID: 103 where the address code 4 exists is detected, the user is inquired whether or not to narrow down by the new address, and the new address is selected. The address codes 3 and 4 are targeted for narrowing down, and when the old address is selected, only the address code 4 is targeted for narrowing down.

FIG. 14 is a diagram showing an update data creation processing flow.
The change target address ID is acquired from the update data (step S1), and the municipality change type is determined (step S2). It is determined whether or not the municipality change includes a merger (step S3). If the merger includes a merger, the address code group to be searched for by the merger is acquired (step S4), and then there is an administrative division. (Step S5), if there is a subdivision, generate subdivided polygon information (step S6), then determine whether there is a change in the address name (step S7), and if there is a change in the address name The changed address name is set (step S8).

FIG. 15 is a diagram showing a flow of updating the narrowed data.
First, target address narrowing data is acquired (step S11), and it is determined whether there is a change in address name (step S12). If the address name is changed, the address name data is updated (step S13). Next, it is determined whether there is a change in the address code (step S14), and if there is a change, the target address code is updated (step S15), and then it is determined whether there is subdivision data (step S16). If there is digitized data, extended data is created (step S17). When the old address data is left, after obtaining the target address narrowing data, a new entry is secured, the information is copied, and after copying, the past data flag (shown in FIG. 12C) is shown in the original data. Set “Old”). In addition, the address narrowing data on the absorbed side should be updated with the information to the effect that it will be separately made into past data, or the search target address code including the updated address code should be made into past data (old) It may be.

FIG. 16 is a diagram showing an address narrowing process flow.
First, target address narrowing data is acquired (step S21), and it is determined whether all search target address codes have been checked (step S22). If all search target address codes have not been checked, the address code of the facility is narrowed down. It is determined whether or not it is an address code. If it is a narrowed-down address code, it is registered as target data and set as a list display target (step S24), and the above processing is performed until all search target address codes are checked.

FIG. 17 is a diagram illustrating a facility address display processing flow, and FIG. 18 is a diagram illustrating facility address display processing.
In FIG. 17, first, a record including the address code of the facility in the search target address code is acquired (step S31), and it is determined whether there are a plurality of records (step S32). If there are not a plurality of records, it is determined that the data has not been updated, and the address name of the acquired record + the address character of the facility information is set as the facility address character (step S33). When there are a plurality of records in step S32, a record that includes the address code of the facility in the search target address code and has the smallest number of search target address codes is acquired (step S34). In this process, for example, in the case of FIG. 18A, there are a plurality of address codes 3 and 4 in the address ID: 103, and when looking at the address code 4, the address ID: 104 does not require only one address code. This data is obtained by determining that the address code is old. Next, the address name of address code 4 is connected to Horikawa City, ○○ Prefecture, with address address Nambokucho, 1-chome, Horikawa Park (Address Code 4), as shown in Fig. 18 (c). Add (old) to the end of 1-chome, Namboku-cho to make the address letter of Horikawa Park.

FIG. 19 is a diagram showing another example of the facility address display processing flow, and FIG. 20 is a diagram for explaining the facility address display processing.
First, it is determined whether there is old narrowing data (step S41). As shown in FIG. 20A, the old address ID: 103 and the old address code 3, the old address ID: 104 and the old address code 4 are added to the new address code 3 and 4 of the address ID: 103. This is a process of checking whether or not If there is old refined data, the address name of the old address refined data + the address character of the facility information + “old” is set as the facility address character (step S42). For example, the old address ID: 103, the old address code 3, the old address name Haruna City, XX Prefecture, and the Haruna Police Station, the address code 3, and the address address 2-2-2, Tozaimachi are shown in FIG. 20 (c). As you can see, the address letter of the Haruna Police Station is 2-2 Higashi Nishimachi, Haruna City, XX Prefecture (old). If there is no old screening data, the address filtering data is acquired, and the address name of the acquired address filtering data + the address character of the facility information is set as the facility address character.
