1 is a configuration diagram of a number search navigation system according to the present invention, Figure 2 is an internal configuration diagram of a database of the number search navigation system according to the present invention.

Referring to FIGS. 1 and 2, the GPS number search navigation system includes a GPS module 100 that receives information about a current position of a vehicle through a satellite, an input unit 300 for receiving a user's operation command, or a number, and the database. Extracting POI information corresponding to the number input from the input unit, generating a POI list using the extracted POI information, and generating route data to one POI position among the POI lists selected through the input unit The control unit 400 includes a database unit 200 storing the POI information and map information, and a display unit 500 for outputting the POI list or route data.

The GPS module 100 includes a driving sensor unit (not shown) which detects a driving state of an antenna 110 and a moving object that receive navigation messages transmitted by a plurality of GPS satellites to the GPS module 100 and outputs a detection signal. When the moving object is driven through the navigation message and the detection signal to determine the current position of the moving object.

The database unit 200 includes a POI information database 210 and a map database 220. The POI information database 210 records each POI information on the map data.

The POI information is data indicating coordinates of facilities such as an airport, a terminal, a department store, and the number of each facility, which is very accurate. For example, the coordinate values of longitude and latitude and "122 Bongrae-dong, Jongno-gu, Seoul" in connection with a facility called "Seoul Station" stored in the POI information database 210 can be used. Includes class numbers such as Seoul, Jongno-gu, Bongrae-dong, and 122 divided by

For the number included in the POI information of the POI information database 210, referring to Table 1 below, a first class consisting of a province, a metropolitan city, and a city, a second class consisting of a general city, and a county Class, 3rd class consisting of 'gu' and 'eup', 4th class consisting of 'myeon' and 'dong', 5th class consisting of 'Lee', 6th class storing address, etc. And structure name of POI are stored.

Name of structure First class 2nd class 3rd class 4th class 5th class 6th class Seoul Station Seoul Jongno-gu Bongrae-dong 122 addresses Chiaksan Gangwon-do Wonju Socho noodles Hakgokri 900 addresses

In addition, the branch included in the POI information of the POI information database 210 is composed of a first class consisting of 'province', 'a metropolitan city' and 'a city', 'general city', and 'county', referring to Table 2 above. The same class as the second class, the third class consisting of 'gu' and 'eup', the fourth class consisting of 'myeon' and 'dong', the fifth class consisting of 'road name', and the sixth class storing building number. The divided branch and the structure name of the POI are stored.

The branch is the new address of "road name and building number" effective April 5, 2007. For example, the address of '58 -1 Samsung-dong, Gangnam-gu, Seoul 'is changed to a new address such as' Hakdong-ro 2, Gangnam-gu, Seoul'.

Name of structure First class 2nd class 3rd class 4th class 5th class 6th class Seoul Station Seoul Seocho-gu Gangnam-daero 442 Chiaksan Gangwon-do Wonju Socho noodles Kowloon Saro 91

The map database 220 stores the geographic information produced by the numerical data according to a predetermined format of the POI information about the actual road, building, or facility surveyed in advance. For example, the geographic information stores information on the entire map as digital geographic information such as nodes and links. Nodes are coordinates for specific points on the map. Links connect each node and represent roads, etc. on a map.

The input unit 300 may receive the entire number or the initial unit of the number from the user, or receive an operation command of the navigation system. When the control unit 400 generates a POI list corresponding to the input number, the input unit 300 receives the input number through the input unit 300. Allows the user to select the desired POI from the POI list. In addition, when there is no POI having the same number as the input number, a search radius within a predetermined distance of the input number may be set by the user.

The display unit 500 performs a display of a map under the control of the controller 400, displays a driving route including the current position of the moving object and a POI list generated by the controller 400, and schedules a selected POI from the POI list. If it detects approaching within a distance, it enlarges and displays the path including the selected POI and the current location.

When the control unit 400 receives the input of the number through the input unit 300, the control unit 400 converts the input number into the number of classes.

For example, if "122 Bongrae-dong, Jongno-gu, Seoul" is inputted, the number entered as shown in Table 3 below is a first class consisting of 'Do', 'Gwangju' and 'Gyeong', 'General', 'Gun' The second class consisting of 'gu', the third class consisting of 'gu', 'eup', the fourth class consisting of 'myeon' and 'dong', the fifth class consisting of 'Lee', the same class as the sixth class storing address In order to correspond to the dividing address, the number is divided into 'Seoul Metropolitan City' for the first class, 'Jongno-gu' for the third class, 'Bongrae-dong' for the fourth class, and '122 Address' for the sixth class.

First class 2nd class 3rd class 4th class 5th class 6th class Seoul Jongno-gu Bongrae-dong 122 addresses

In addition, if "442, Gangnam-daero, Seocho-gu, Seoul" is inputted, as shown in Table 4 below, the inputted Jiro is composed of 'first', 'general city', and 'gun' consisting of 'do', 'gwangju' and 'gyeong'. 2 classes, 3rd class consisting of 'gu' and 'eup', 4th class consisting of 'myeon' and 'dong', 5th class consisting of 'road name', 6th class storing building number It is converted into Jiro divided into 'Seoul Metropolitan City' for the first class, 'Seocho-gu' for the third class, 'Gangnam-daero' for the fifth class, and '442' for the sixth class.

First class 2nd class 3rd class 4th class 5th class 6th class Seoul Seocho-gu Gangnam-daero 442

The POI information database 210 checks whether the POI information having the same class number as the input document number is compared by sequentially comparing the input document number and the class of the document number included in the POI information stored in the POI information database 210. Search.

For example, when 'Seoul Metropolitan City' of the first class of the inputted house number is matched with the first class of the house number contained in the POI information stored in the POI information database 210, the third class of the input house number 'Jongno-gu' is compared with the third class of the branch included in the POI information stored in the POI information database 210.

At this time, since the second class of the input number is not applicable, the comparison between the second class of the input number and the second class of the number included in the POI information stored in the POI information database 210 may be omitted.

Comparing with the fourth class to sixth class of the number entered in the above manner and the fourth class to sixth class of the number included in the POI information stored in the POI information database 210, the class has the same class number. If there is POI information, the controller 400 generates a POI list using the POI information having the same class detected.

In addition, when there is POI information having three or more identical classes among the number of the number input in the above manner and the number of the number included in the POI information stored in the POI information database 210, the controller 400 detects the detected three. The POI list is generated using the POI information having the same class.

For example, if the user enters "122 Hongpa-dong, Jongno-gu, Seoul" or "122, Jongno-gu, Seoul" in the input section, matches the first class, the third class, the sixth class, or the first class, the first class. POI information including classes matching the third class, the fourth class, and the sixth class is extracted from the POI information database 210 to generate a POI list.

Compared with the first class to the sixth class of the number included in the branch number input in the above manner and the POI information stored in the POI information database 210, the POI information having the same class number is less than three classes. In the case of having a predetermined radius at the location of the number input from the user or if there is no setting, for example, located within a certain distance from the location of the input number within the predetermined radius stored by default, for example, located within "1km" POI information is extracted from the map database 220.

For example, "122 Bongrae-dong, Jongno-gu, Seoul" is converted to a class and is compared with the first class to the sixth class included in the POI information stored in the POI information database 210. If there is no POI information with "No. 122 Bongrae-dong, Jongno-gu, Seoul" is converted into coordinates of longitude and latitude.

POI information existing within a predetermined radius from the coordinates converted into coordinates is extracted from the map database 220 in which POI information and coordinates of the actual road, building, or facility surveyed in advance are extracted to generate a POI list.

At this time, the control unit 400 generates the POI list arranged in the shortest order from the coordinates of the inputted number of the extracted POIs and displays the POIs that are highly likely to be selected by the user, thereby easily indicating the POIs to be easily set as the destinations. Make a choice.

In addition, the present invention can compare the class as described above by using Jiro (new address changed on April 5, 2007) in addition to the above number (see Table 2, Table 4).

3 is an embodiment of a screen for selecting a POI from a user according to the present invention.

Referring to FIG. 3, the number search navigation system provides a user interface screen for selecting a POI to be set as a destination from the POI list provided by the controller 400 to the input unit 300, and the user via the input unit 300. You can select the POI to be set as the destination. The POI list displayed on the user interface screen may include information such as site number and structure name, distance from the current location, and telephone number.

When the user selects the POI to be set as the destination from the POI list through the input unit 300, the controller 400 generates the route data to the destination using the geographic information of the map information database 220, the GPS module 100 Data obtained by calculating the current coordinates of the moving object corresponding to the position corresponding to the path is transmitted to the display unit 500 together with the path data.

By using the route data, the route to the location of the POI set as the destination is displayed on the display unit 500 so that the user can easily move to a desired place.

When the moving object 410 detects that the mobile object 410 approaches within a certain distance of the POI 420 set as the destination through the GPS module 100, the controller 400 extracts POI information stored in the map database 220 and sets the POI set as the destination. By generating route data including the location of the location 420 and the POI information extracted from the map database 220, the display unit 500 is extracted from the map database 220 and the POI 420 set as the route 430 and the destination. The POI 440 corresponding to the POI information is enlarged and displayed (see FIG. 4).

In addition to the enlarged display method, the displayed route data may indicate a direction 450 by using an arrow or provide a voice guidance of a distance to a direction or a POI location set as a destination (see FIG. 4).

5 is a flowchart of a method for searching for a number according to the present invention.

The user inputs an address to be set as a destination (S510). For example, the user may input the full address of "122 Bongrae-dong, Jongno-gu, Seoul", "122" or "12" or enter the initial name, such as "ㅅㅇ ㅈ ㄹ 122". .

The controller sequentially compares the class number entered in the input unit with the class number included in the POI information stored in the POI information database from the upper class and searches the POI information database for POI information having the same class number as the input number. (S520).

The first class from the first class to the sixth class included in the POI information stored in the POI information database, as shown in Table 1, is converted into the branch number divided from the first class to the sixth class. Compare to the class. If the first class of the input number and the first class of the POI information number are the same, the process proceeds to the lower class and compares them.

In this case, when the second class of the input number is not applicable, the comparison between the second class of the input number and the second class of the number included in the POI information stored in the POI information database may be omitted.

In the same manner as described above, when the comparison between the number of classes entered in the input unit from the first class to the sixth class and the number of classes included in the POI information stored in the POI information database is completed, the controller includes the POI information having the same class number. Extracts POI information having the detected class number (S531) and generates a POI list (S532).

In the same manner as described above, the comparison between the number inputted from the first class to the sixth class and the number of classes included in the POI information stored in the POI information database is completed. If there is, the controller extracts POI information having three or more identical class numbers detected (S532) and generates a POI list (S542).

In the same manner as above, the comparison between the number inputted from the first class to the sixth class and the number of classes included in the POI information stored in the POI information database is completed, so that the POI information having the same class number is less than three. In the case of having a class, POI information located within a predetermined radius stored by default is extracted from the map database when a predetermined radius is set at the location of the input number from the user or when there is no setting (S533).

At this time, the input number is converted into coordinates of longitude and latitude, and the POI information and coordinates of actual roads, buildings, and facilities that have been previously surveyed for POI information existing within a predetermined radius set in the coordinates converted into coordinates are stored. The POI list is generated by extracting from S543.

At this time, the controller generates the POI list sorted in the shortest order from the coordinates of the inputted number and displays the POIs most likely to be selected by the user so that the user can easily select the POI to be set as a destination. do.

A user interface screen for selecting a POI to be set as a destination from the POI list provided by the controller is provided to the input unit, and the POI to be set as the destination is selected through the input unit (S550).

When the user selects the POI set as the destination from the POI list through the input unit, the controller generates the route data to the destination using the geographic information of the map information database, and then the current coordinates of the moving object obtained from the GPS module are located on the route. The calculated data corresponding to the data is transmitted to the display unit along with the route data (S560), and the route to the location of the POI set as a destination is displayed on the display unit using the route data (S570).

When the moving object detects that the moving object approaches within a certain distance of the POI set as the destination through the GPS module (S580), the controller extracts the POI information stored in the map database to include the location of the POI set as the destination and the POI information extracted from the map database. By generating the route data (S590), the display unit enlarges and displays the route data (S600).

In addition, the present invention can search the branch by using the branch search method (new address changed on April 5, 2007) in addition to the branch number search method as described above (see Table 2, Table 4). In addition, in this invention, the branch was included in the branch and demonstrated.
