  The present invention relates to a navigation system that can guide a customer who guides a route to a location of interest (POI) where a general customer has shown interest to the location of interest. A spot request ID is added to the map request link for requesting the map data including the interest location where the interest is shown, and the map data is distributed and the route is set with the spot ID as the destination. The present invention relates to a navigation system that guides customers by searching for.

  2. Description of the Related Art Conventionally, navigation devices and navigation systems that guide a user by searching for a route from a desired departure point to a destination using map data and road data are known. Such navigation devices and navigation systems are known. As a car navigation device that is installed in an automobile and guides the route to the driver, a communication type that uses a mobile phone as a navigation terminal to send a route search request to the route search server, receives the result, and receives route guidance Navigation systems have been put to practical use.

  In particular, the communication-type navigation system is a system that uses a mobile terminal such as a mobile phone as a navigation terminal, and is also used as a navigation system for pedestrians. As a navigation system for pedestrians, it is preferable to add a route guidance function including transportation, and in addition to searching and guidance for walking routes, the route search server accumulates routes and operation time data of transportation, There is also a navigation system having a function of guiding a route from a desired departure station to a desired destination station (boarding candidate train) in addition to searching for a walking route and guidance. There is also a traffic guidance system that receives and displays information such as routes, timetables of transportation facilities, and trains that can be boarded from an information distribution server without searching for walking routes.

  A general navigation device, a route search device and a route search method used in a communication navigation system are disclosed in, for example, the following Patent Document 1 (Japanese Patent Laid-Open No. 2001-165681). This navigation system is configured to send information on a departure point and a destination from a portable navigation terminal to an information distribution server, and the information distribution server searches and guides a route that matches a search condition from road network and traffic network data. Has been. As the search condition, there are means for moving from the departure place to the destination, for example, walking, automobile, combined use of railroad and walking, and the route is searched as one of the search conditions.

  The information distribution server has roads (routes) of map data as nodes and nodes as the positions of inflection points, links connecting the nodes as links, and cost information (distance and required time) of all links as a database. ing. Then, the information distribution server sequentially searches for a link from the departure node to the destination node with reference to the database, and traces the node and link with the smallest cost information of the link as a guide route. The shortest route can be guided to the portable navigation terminal. As such a route search method, a method called label determination method or Dijkstra method is used. Patent Document 1 also discloses a route search method using this Dijkstra method.

  A route search system that searches for routes that use transportation is a database of operation time data of each transportation based on route search conditions such as departure date, departure location, destination, arrival time specified by the user. It has a time database and data that makes the traffic network a database based on this. Then, referring to these databases, each available means of transportation (individual trains and route buses) connecting the departure point and destination, including connections (transfers), is sequentially traced to meet the route search conditions. It is configured to present one or a plurality of candidates for a guide route (departure station, destination station, route, train, etc.). As route search conditions, it is generally possible to specify conditions such as required time, number of transfers, and fares.

  The search data in the route system using the transportation system and the navigation system that guides the route is the same as the road network data in the in-vehicle navigation system and the pedestrian navigation system. In addition to the data networked as a bidirectional link, the operation time and required time of each link are added as link cost data for each means of transportation operated on each traffic route. Furthermore, there is a system in which fare data is added and the fare of the searched guide route is guided together.

  Also, in such a navigation system, a facility that is a place of interest (POI) that a user wants to visit is searched, and a route from the current position of the user or a desired departure place to the corresponding POI is searched. A system that can guide you is provided. The POI includes, for example, a wide variety of hotels, well-known buildings, facilities, facilities for shopping and eating, public facilities, and event venues.

  In this case, the route search server is provided with a POI database for searching for a POI. The route search server stores POI information in various POI databases obtained from various information distribution servers using a communication network such as the Internet. Various methods have also been proposed for the user to select POI as a destination. In addition to a method for searching by entering a facility name, telephone number, address, etc., a map including the current position of the user is displayed on the map. A method for selecting a POI icon image displayed on the screen has been proposed.

  As a result of the POI search, a system that requests map data including the POI to the server, and transmits a route search or route guidance request to the POI to the server is disclosed in, for example, the following Patent Document 2 (Japanese Patent Laid-Open No. 2001-2001). No. 306716). This system is configured such that when a POI search server transmits information on a specific POI as a result of the POI search to the terminal device, the POI search server adds the position information of the POI to the map request link to the map distribution server. Has been. When the terminal device operates the received map request link, the terminal device is connected to the map distribution server, and the map data including the POI is transmitted to the terminal device based on the POI position information.

  Further, the user is provided with route guidance to the POI as the destination by the user, and when the user visits the POI, the operator of the route search server pays the guidance success fee to the operator of the POI. There are also known navigation systems that charge users. For example, it is disclosed as a success management system in the following Patent Document 3 (Japanese Patent Laid-Open No. 2006-330943).

  The success management system disclosed in Patent Document 3 receives success information received from a mobile terminal device and notifies that the mobile terminal device has successfully navigated to a store from the mobile terminal device and counts it up to the number of successes. And stores a management unit that stores the number of successes in association with a store ID for identifying each store, a store ID, billing destination information that is associated with the store ID and specifies a billing destination, and a number of successes. And a calculation unit that reads the billing destination information and the number of successes from the storage unit and calculates a billing amount to be billed for each billing destination as a price for successful navigation.

When the processing request is based on the above-described link information, the link information is also temporarily stored in the processing request storage unit 38.

The POI determination means 33 determines whether or not there is a specific spot ID included in the link information, and determines whether or not the processing request based on the link information is a POI that provides a route guidance service for non-registered members. The effective period determination unit 331 determines whether an effective period is registered in the specific spot ID in the POI having the specific spot ID. This determination can be made by referring to the POI information database 36. In addition, when the valid period information is recorded together with the specific spot ID in the link information, the valid period can be determined from the link information.

  In the terminal device 20, the control means 201 is a microprocessor having a RAM, a ROM, and a processor (not shown), and controls the operation of each unit by a control program stored in the ROM. The communication means 21 is a communication interface for transmitting and receiving communication data with the route search server 30 and the like via the network 12.

  The GPS receiving means 21 receives a signal from a GPS satellite and calculates the current position by latitude and longitude. The operation input means 27 is composed of keys, dials and the like, performs input for operating the terminal device 20, and is also used as an input function for a departure place, a destination, and the like. The display means 26 comprises a liquid crystal display panel or the like, and is used for displaying a guidance route, a recommended route, or a map distributed (transmitted) from the route search server 30. The display means 26 also functions as an input means for displaying the menu screen and operating the terminal device 20.

  Guide data such as a guide route and a recommended route transmitted from the route search server 30 to the terminal device 20 is stored in the received data storage unit 25 together with the map data, and the guide data such as the guide route stored in the received data storage unit 25 The map data is read as necessary and displayed on the display means 26.

  The condition setting unit 24 sets a route search condition based on information input by the operation input unit 27 or based on information input by operating the menu screen or the condition input screen displayed on the display unit 26. Set. As a route search condition, a departure point, a destination, a waypoint, a moving means, a time condition, and the like are used as in a general navigation system.

  The processing request unit 23 operates a route search request based on the route search condition set by the condition setting unit 23 or a link request acquired by the terminal device 20 using the QR code or the like, and sends a processing request based on the request to the route search server. 30.

  When the processing request from the terminal device 20 to the route search server 30 is a processing request based on the link information described above, the link information is temporarily stored in the processing request storage unit 38. The member determination unit 32 performs authentication by referring to the registered member database 37 based on the ID of the terminal device 20 that has transmitted the processing request, and determines whether the processing request is a registered member or a non-member processing request.

  The POI determination unit 33 refers to the link information stored in the processing request storage unit 38 and determines whether or not the specific spot ID is included in the POI information of the link information. When the specific spot ID is included and the member determination unit 32 determines that the request is a processing request by a registered member, the route search server 30 searches for a route with the POI specified by the specific spot ID as a destination, Accept route guidance.

  When the route guidance by the specific spot ID is accepted, the route searching means 39 refers to the route search network database 35 and searches for the route with the POI specified by the specific spot ID as the destination, a map including the POI, The guide route is displayed on the terminal device 20 that is the processing request source. The starting point of the route search may be the current position of the terminal device 20, or the terminal device 20 may be set to the starting point.

  Hereinafter, when the terminal device 20 that has acquired the link information as described in FIGS. 4 and 5 accesses (process requests) the route search server 30 based on the link information, a link screen (displayed on the terminal device 20) URL browser screen) will be described. However, the following description is a case where the user of the terminal device 20 that has accessed the route search server 30 based on the link information is not a registered member. That is, it is an explanation when the member determination unit 32 authenticates the terminal device 20 and determines that the access is from a non-registered member.

  FIG. 7 shows a route guidance link screen (URL browser screen) displayed on the terminal device 20 when the terminal device 20 accesses (links) the route search server 30 with link information including a specific spot ID and receives a processing request. The structure of is shown. In the example of FIG. 7, the link information including the POI information acquired by the terminal device 20 is the information of the A restaurant, the operator of the A restaurant registers the specific spot ID, and the link information includes the specific spot ID. Shows the case.

  When the POI information (address, telephone number, etc.) 402 of the A restaurant is displayed on the screen, and the display character string “Confirm Map” is clicked, the route search server 30 displays a predetermined range including the location of the A restaurant. Is displayed on the display means 26. In addition, since the specific spot ID is included in the link information used by the terminal device 20 to access the route search server 30 (A restaurant registers the specific spot ID), the link to the route guidance is indicated. A route guidance link 403 is displayed.

  The display character string “set as destination (route guidance)” displayed on the route guidance link 403 indicates that a route search and route guidance service with the A restaurant as the destination can be received. Is also displayed as free. When the character string “set as destination” is clicked, the route search means 39 searches the route search network database 35 for a guide route with the destination as the A restaurant, and displays the route together with the map data 26. To display.

  A departure place is required for route search, but when the character string “set as destination” is clicked, the input of a departure place and a selection screen are displayed as a sub screen, and the current position of the terminal device 20 is selected, What is necessary is just to comprise so that the user of the terminal device 20 may input desired point information.

  A display character string of “detailed information” is displayed in the display of recommended information, and when this character string is clicked, sales information such as recommended food of A restaurant is displayed. In addition, when the display character string “issue coupon” is clicked, a discount coupon is issued to the terminal device 20. The navigation menu 404 displays normal menu items used by registered members, and the map / route 405 displays a display menu of a route map and a character link to a note during map display.

  In this way, the screen of FIG. 7 is a page where only “Set as Destination” can be selected in the route guidance. In addition, since this is based on the flow of advertisements, a link for acquiring a coupon as shown in the figure or an effective comment is displayed in order to further ensure the visit of the user. For example, when “set as destination” is selected, the specific spot ID (POI operator) is charged. The billing may be a uniform billing for the POI with a valid period.

  FIG. 8 is a diagram illustrating a configuration of a link screen displayed on the terminal device 20 when a processing request is issued to the route search server 30 by link information that does not include a specific spot ID. In the example of FIG. 8, the link information including the POI information acquired by the terminal device 20 is the information on the A restaurant, the operator of the A restaurant does not register the specific spot ID, and the specific spot ID is included in the link information. The case where it is not included is shown.

  In this case, the POI information (address, telephone number, etc.) 502 of the A restaurant is displayed on the display screen 300, and only the display character string “confirm map” is displayed, and a link to route guidance as shown in FIG. The string is not displayed. When the display character string “confirm map” is clicked, the route search server 30 displays a predetermined range of map images including the location of the restaurant A on the display means 26. Other display contents such as the navigation menu 504 and the map / route 505 are the same as those in FIG.

Next, a route guidance service procedure according to the first embodiment of the present invention will be described.
FIG. 9 is a flowchart illustrating the procedure of the route guidance service according to the first embodiment of the present invention. First, in the process of step S101, a processing request based on the link information is made from the terminal device 20 to the route search server 30.

  When there is this processing request, the route search server 30 stores the processing request (link information) from the terminal device 20 in the processing request storage unit 38. Then, in the process of step S102, the member determination unit 32 refers to the registered member database 37 to perform the authentication process of the terminal device 20, and determines whether or not the user is a registered member in the navigation system. If the user is a member, the process proceeds to step S107, and a normal route search start screen provided to the member is displayed on the display means 26 of the terminal device 20. On this screen, the user can set a desired condition (departure point, destination) and request a route search and route guidance service. The POI and specific spot ID included in the link information can also be selected as the destination.

  If it is determined in step S102 that the user is not a member, the POI determination unit 33 determines whether or not a specific spot ID is added to the POI information included in the link information in step S103. . If the specific spot ID is not added, the process proceeds to step S105, and only map distribution is provided as described with reference to FIG.

In the determination process of step S103, if the POI determination means 33 determines that the specific spot ID is added to the POI information included in the link information, the process proceeds to step S104, and the valid period determination means 331 stores the POI information database 36. With reference to it, it is determined whether or not an effective period is set for the specific spot ID. If an effective period is set, it is determined whether or not it is within the effective period.

  In the determination process of step S104, if the effective period determination unit 331 determines that it is not within the effective period of the specific spot ID, the process proceeds to step S105, and if it is determined to be within the effective period, the process proceeds to step S106. . In the process of step S106, the route search start screen (link screen to route guidance) described in FIG. 7 is displayed, and the terminal device 20 selects the destination as a specific spot ID (position of POI with a specific spot ID added). It is possible to link to the route search and route guidance service.

  When a route search or route guidance service is requested in the process of step S106 or step S107, the route search means 39 searches the route search network database 35 for a route to the destination, and is obtained as a result. The guide route data and map data are distributed to the terminal device 20 and the map image and the guide route image are displayed on the display means 26.

  Next, the concept of route search in the route search server 30 will be described. In the route search network database 35 in the route search server 30 constituting the pedestrian navigation system and the car navigation system, road network data and traffic network data are accumulated.

  For example, road network data used for walking or route search by an automated person is configured as follows. When the road is composed of roads A, B, and C as shown in FIG. 10, the end points, intersections, and inflection points of the roads A, B, and C are used as nodes, and the roads connecting the nodes are represented by directional links. , Node data (node latitude / longitude), link data (link number), and link cost data with link cost (link distance or time required to travel the link) of each link as data. The

  That is, in FIG. 10, Nn (◯ mark) and Nm (◎ mark) indicate nodes, and Nm (◎ mark) indicates a road intersection. Directional links connecting the nodes are indicated by arrow lines (solid line, dotted line, two-dot chain line). As for the links, there are links facing in the upward and downward directions of the road, but in FIG. 10, only the links in the direction of the arrows are illustrated for the sake of simplicity.

  When route search is performed using such road network data as a route search database, links linked from the starting node to the destination node are traced to accumulate the link cost, thereby minimizing the accumulated link cost. Search and guide the route. That is, in FIG. 10, when a route search is performed with the departure point as the node AX and the destination as the node CY, the road travels from the node AX along the road A, turns right at the second intersection, enters the road C, and reaches the node CY. The link cost is accumulated sequentially, and a route that minimizes the accumulated link cost is searched for and guided.

  Although other routes from the node AX to the node CY are not shown in FIG. 10, there are actually other such routes, so that a plurality of routes that can be reached from the node AX to the node CY are displayed. A search is performed in the same manner, and a route with the lowest link cost is determined as the optimum route. This method is performed by, for example, a known method called the Dijkstra method.

  On the other hand, the traffic network data for route search of the transportation system is configured as follows. For example, as shown in FIG. 11, in the case of traffic routes A, B, and C, each station (each airport on an aircraft route) provided on each traffic route A, B, and C is a node, and the nodes are connected. A section is represented by a directional link, and node data (latitude / longitude) and link data (link number) are network data. In FIG. 11, Nn (◯ mark) and Nm (◎ mark) indicate nodes, Nm (◎ mark) indicates a transit point (such as a transfer station) on a traffic route, and a directional link connecting each node. It is indicated by an arrow line (solid line, dotted line, two-dot chain line). As links, there are links facing in the upward and downward directions of the traffic route. In FIG. 11, only the links in the direction of the arrows are shown for the sake of simplicity.

  However, the traffic network basically has a different link cost compared to the road network. That is, in the road network, the link cost is fixed and static, but in the traffic network, as shown in FIG. 11, trains and airplanes (hereinafter referred to as individual trains and airplanes) that operate the traffic route are used. A plurality of means of transportation). The time of departure from one node and the time of arrival at the next node are determined for each means of transportation (specified by timetable data and operation data), and individual routes do not necessarily link to adjacent nodes. There is a case. This is the case, for example, with express trains and trains that stop at each station. In such a case, a plurality of different links exist on the same traffic route, and the required time between nodes may differ depending on the transportation means.

  In the transportation network illustrated in FIG. 11, a plurality of transportation means (routes) Aa to Ac... Exist on the same link of the transportation route A, and a plurality of transportation means (routes) Ca to Cc. Will do. Therefore, unlike a simple road network, the transportation network of a transportation facility has a data amount proportional to the total number of transportation means (routes such as individual airplanes and trains). For this reason, the data of the traffic network becomes a huge amount of data compared to the data amount of the road network. Accordingly, much time is required for route search accordingly.

  In order to search for a route from a certain departure point to a certain destination using such traffic network data, all the means of transportation that can be used (ride) when arriving from the departure point to the destination are searched. It is necessary to specify the means of transportation that matches the search conditions.

  For example, in FIG. 11, when performing a route search in which the departure point is a node AX of the traffic route A and a certain departure time is specified and the node CY of the traffic route C is the destination, the route operates on the traffic route A. Of the transportation means Aa to Ac..., All transportation means after the departure time are sequentially selected as the departure route. Based on the arrival time at the transit node on the transit route C, among all the transit means Ca to Cc... Operating on the transit route C, all combinations of transit means after the time that can be boarded at the transit node. The total time required for each route, the number of transfers, and the like are guided.

  Next, the structure of the map data stored in the map database 34 will be described. The map data stored in the map database 34 is composed of unit map data divided by a predetermined latitude / longitude range as shown in FIG. In this way, the map data is divided into map areas in units of predetermined latitude and longitude, and is configured as mesh unit map data M11 to M33. When distributed to the terminal device 20, the unit map data M21, M23, M12, and M32 adjacent to the unit map data M22 including the current position PP of the terminal device 20 in the vertical direction, the horizontal direction, and the diagonal direction are centered. , M11, M13, M31, and M33, a total of nine unit maps are distributed.

  When the terminal device 20 moves and the map data is insufficient, the moving direction of the terminal device 20 is determined, and the route search server 30 distributes the insufficient unit map data. The same applies when the terminal device 20 makes a distribution request for map data by designating a specific point or POI (Point of Interest) position. The guide route data is distributed to the terminal device 20 together with the vector map data. The terminal device 20 thus receives the map data and the guidance route data from the route search server 30 and displays the map and the guidance route on the display means 26.

  The navigation system 10 according to the first embodiment described above identifies the terminal device 20 when the terminal device 20 that acquired the link information as described in FIGS. 4 and 5 is not a registered member of the navigation system 10. A limited route guidance service with a spot ID as a destination was provided free of charge. When the terminal device 20 is a registered member, a route search and route guidance service is provided via a normal route search start screen.

  On the other hand, it is also possible for the registered member to automatically proceed to route guidance with the specific spot ID as the destination. Hereinafter, a navigation system according to Example 2 of the present invention configured as described above will be described. The configuration of the navigation system 10 is the same as that of the navigation system 10 of the first embodiment, and the description thereof is omitted.

  FIG. 13 is a flowchart illustrating the procedure of the route guidance service according to the second embodiment of the present invention. First, in the process of step S201, a processing request based on the link information is made from the terminal device 20 to the route search server 30.

  When there is this processing request, the route search server 30 stores the processing request (link information) from the terminal device 20 in the processing request storage unit 38. Then, the POI determination unit 33 determines whether or not a specific spot ID is added to the POI information included in the link information in the determination process of step S202. If the specific spot ID is not added, the process proceeds to member determination processing in step S204.

In the determination process of step S202, if the POI determination unit 33 determines that the specific spot ID is added to the POI information included in the link information, the process proceeds to step S203, and the valid period determination unit 331 stores the POI information database 36. With reference to it, it is determined whether or not an effective period is set for the specific spot ID. If an effective period is set, it is determined whether or not it is within the effective period.

  In the determination process of step S203, when the effective period determination unit 331 determines that it is not within the effective period of the specific spot ID, the process proceeds to the member determination process of step S204. In the determination process of step S203, when the effective period determination unit 331 determines that it is within the effective period of the specific spot ID, the process proceeds to step S206. In the process of step S206, the route search start screen (link screen to route guidance) described in FIG. 7 is displayed, and the terminal device 20 displays the destination as a specific spot ID (position of POI with a specific spot ID added). It is possible to link to the route search and route guidance service.

  On the other hand, in the member determination process of step S204, the member determination unit 32 refers to the registered member database 37 to perform the authentication process of the terminal device 20, and determines whether the user is a registered member in the navigation system. If the user is a member, the process proceeds to step S207, and a normal route search start screen provided to the member is displayed on the display means 26 of the terminal device 20. On this screen, the user can set a desired condition (departure point, destination) and request a route search and route guidance service.

If it is determined in step S204 that the user is not a member, the process proceeds to step S205, and only map distribution is provided as described with reference to FIG.
When a route search or route guidance service is requested in the processing of step S206 or step S207, the route search means 39 searches the route search network database 35 for a route to the destination, and is obtained as a result. The guide route data and map data are distributed to the terminal device 20 and the map image and the guide route image are displayed on the display means 26.

In addition, since there is a difference in the charge burden of the navigation system 10 between the registered member and the non-registered member, it is also necessary to provide higher added value for the service for the registered member than for the service for the non-member. For example, in the route guidance service in step S206, in the case of route guidance for a member, a route network by a free shuttle bus provided by a POI set as a destination is accumulated as specific network data. By providing route guidance that takes into account, it becomes possible to make a reasonable difference between the route guidance service for non-members and the route guidance service for members.

  As described above in detail, according to the navigation system of the present invention, if the POI operator has registered a specific spot ID to provide a route guidance service at a certain cost, the POI is displayed. Even if the user who sends the specified processing request is a general user who is a non-member of the navigation system, the navigation system can provide limited route guidance with the POI as a destination free of charge. Become.

  In addition, since the destination is fixed, it is easy to use even for non-members with little experience. Since both members and non-members operate on the same map link (processing request), the load on the route search server does not become excessive. Even if the specific spot ID is copied and pasted to another link, since the POI corresponding to the specific spot ID is guided, it cannot be illegally used. The validity period can be managed by the route search server. Such effects can be obtained.

  In the present invention, even if the user is not a member of the navigation service, the navigation service can be provided at the burden of the advertisement provider (POI operator). Therefore, the route guidance service can be widely provided to general users. . Accordingly, the advertisement provider can increase the ability to attract customers. Further, since the navigation service is limited to the destination intended by the advertisement provider, there is no inconvenience that the service is used without limitation.
