Here, the conventional system has the following problems.
The first problem is that although route information on the ground is maintained, preparation of route information on the underground and indoors necessary for providing a route guidance service for the underground and indoors does not proceed.
The reason is that in order to realize underground and indoor route guidance services using the same method as the conventional ground, it is necessary to create route information based on a map expressed in latitude and longitude. This is because, in order to create a map expressed in latitude and longitude, a specialized cartography company is requested, so it is very expensive.

The second problem is that even if the route information in the basement and indoors is created using a map that is cheaper to produce than illustrations such as illustration maps, it can only provide route guidance within the created range. It is.
The reason is that, since the coordinate representation is different between the illustration map and the latitude / longitude map, the conventional method cannot regard the route information created by each map as one connected route information.

In the embodiment of the present invention, the above-described conventional problems are mainly solved as follows.
The first solution is to make it possible to create route information by a GUI (Graphical User Interface) operation on a map that is not expressed in latitude and longitude. Thereby, the cost of creating route information can be greatly reduced.
The reason is as follows.
The cost of creating a new map can be reduced by using an illustration map for guidance already created for store guidance and used for route guidance on homepages and passages.
The route creation function capable of GUI operation makes it possible to create route information even if it is not a specialist in route information creation, and the route information creation cost can be reduced.

As a second solution, by matching and creating information necessary for route calculation from route information created on maps with different coordinate representations, and defining connection information between each coordinate representation map is there. This makes it possible to provide route guidance services between maps with different coordinate expressions.
The reason for this is as follows: By matching the route information created in different coordinate representation maps and defining the connection information, it is possible to calculate the route with the origin and destination set between the different coordinate representation maps. Is possible. Further, the result can be displayed as a route line on each coordinate expression map. By using these functions, a route guidance service between maps with different coordinate expressions can be realized.

Here, the above-described wireless information sign (wireless location information transmitter) 5 will be described. As shown in FIG. 2, a large number (three in the illustration of FIG. 2) of the wireless information signs 5 (5a, 5b,...) Are fixedly installed in a predetermined service area. Each wireless information indicator 5 holds position information and other information that can identify the installation position. Then, position information and other information are transmitted by radio waves.
In FIG. 2, the inside of the circle indicated by reference numeral 500 indicates the radio wave reachable range.

The information that can specify the installation position is, for example, information on the position and the number of floors (for example, 3 floors above ground, 2 floors below ground), etc. Good.
When the wireless information sign 5 holds the information for specifying the position on the plane coordinates and the information for specifying the height, the route guidance result display terminal 3 enters the radio wave arrival range of the wireless information sign 5. By receiving information capable of specifying the installation position from the wireless information sign 5, the route guidance result display terminal 3 can accurately specify the current position even in an indoor environment having a plurality of floors.

Instead of the configuration in which the wireless information sign 5 holds information for specifying the position on the plane coordinates and information for specifying the height, the wireless information sign 5 holds the sign ID, and the transmitted sign ID is routed. The guidance result display terminal 3 may transmit the position information and the height information (floor information) from the sign control server by transmitting to the sign control server (not shown).
According to this configuration, data transmitted and received between the wireless information sign 5 and the route guidance result display terminal 3 by wireless communication can be only the sign ID, and the wireless communication data can be reduced. Further, even when the wireless information sign 5 is suspended or newly installed, the information for specifying the position and the information for specifying the height can be corrected only by the sign control server, thereby improving maintainability. Can do.

  FIG. 3 is a block diagram illustrating a configuration example of the wireless information indicator 5. In the example illustrated in FIG. 3, the radio unit 52 receives a high-frequency signal based on the radio wave received by the antenna 51. The radio unit 52 converts the received signal into a low frequency signal and outputs the signal to the receiving unit 54. The receiving unit 54 performs demodulation processing or the like on the input signal and outputs the obtained data (digital signal) to the control unit 55. The control unit 55 is configured by, for example, a microcomputer, and performs control according to data input from the reception unit 54. If the data input from the receiving unit 54 is data indicating position information or other information, it is stored in the storage unit 56.

  In addition, the control unit 55 periodically outputs data indicating position information and the like to the transmission unit 53 at predetermined time intervals. The transmission unit 53 performs modulation processing or the like on the input data and outputs a signal to the radio unit 52. The wireless unit 52 converts the input signal into a high frequency signal and outputs it to the antenna 51. The antenna 51 transmits a radio wave based on a high frequency signal. The transmission unit 53 includes a transmission power amplifier 53A that can change the amplification factor. Control unit 55 outputs a control signal corresponding to a predetermined output power level stored in storage unit 56 to transmission power amplifier 53A. The transmission power amplifier 53A sets the amplification factor according to the control signal so that the output power level of the transmitted radio wave becomes a predetermined output power level. Note that there is no need to constantly output a control signal from the control unit 55 to the transmission power amplifier 53A, and the control signal from the control unit 55 is latched in the transmission unit 53.

  The output power level stored in the storage unit 56 is set to an initial value when the wireless information indicator 5 is installed, but may be changed based on information transmitted from the outside of the device thereafter. .

  Since the wireless information indicator 5 has the above-described configuration, as shown in FIG. 4, a range in which a radio wave from any one of the wireless information indicators 5 does not reach (a radio wave non-arrival range) is as possible as shown in FIG. The radio wave intensity, that is, the output power of each radio information marker 5 is reduced so that the range (radio wave collision range) in which radio waves from a plurality of radio information markers 5 are received in an overlapping manner is as small as possible. decide.

That is, as illustrated in FIG. 4A, when the output power level is higher than the optimum output power level so that the radio wave non-arrival range is as small as possible and the radio wave collision range is as small as possible, The level is lowered. Also, as illustrated in FIG. 4B, when the output power level is lower than the optimum output power level, the output power level is increased.
FIG. 4B shows an example in which the middle wireless information indicator 5b is paused. By adjusting the output power in this way, even when the radio information sign 5 is paused as illustrated in FIG. 4B or when the radio information sign 5 is added, The optimum output power level in the situation can be maintained.

The adjustment of the output power level includes, for example, an instruction input from the outside, an instruction input from a sign control server (not shown), exchange of output power level information between the wireless information signs 5, and arrival of radio waves between the wireless information signs 5 Various methods such as exchange of information indicating a range may be used.
The adjusted output power level is written in the storage unit 16 by the control unit 15, and the control unit 15 thereafter outputs a control signal indicating the newly written output power level to the transmission power amplifier 13A. Will be.

  Wireless communication between the wireless information sign 5 and the route guidance result display terminal 3 is realized by low-power communication such as Bluetooth (registered trademark) or various standards of wireless LAN.

  By using the wireless information sign 5 as described above, the route guidance result display terminal 3 can accurately acquire current position information by adding the concept of height even in a building having a plurality of floors. it can.

Next, map information stored in the ground route information storage unit 22 and the underground / indoor route information storage unit 25 in the route information creation system according to the present embodiment will be described.
The route information storage unit 22 on the ground stores data in which route information is registered in the map information created by the coordinate expression of latitude and longitude, or map information in which the route is not registered.
The underground / indoor route information storage unit 25 stores data in which route information is registered in map information created by coordinate expressions other than latitude and longitude, or map information that has not been registered.
Thus, by storing arbitrary map information in any place, it can be utilized as map information used in the route information creation system as the present embodiment.

In addition, when storing map information in which route information is registered in advance, the range of responsibility of each person in charge is limited to only the area that the person in charge knows well so as to further improve maintainability. Good.
In this case, the person in charge of route information registration may be managed by further providing a person in charge information registration unit (not shown) so that the areas in charge of each person in charge do not overlap.
With this configuration, it is possible to include detailed information about each route and to update the detailed information in real time.

  The route information stored in the ground route information storage unit 22 and the underground / indoor route information storage unit 25 is between the ground map (with latitude / longitude information) and the underground / indoor map (without latitude / longitude information). By making it possible to convert the format (data format) into a common format, continuous route information can be created by joining together regardless of the presence or absence of latitude and longitude information.

  Next, an operation of registering route information in a map created by coordinate expression based on latitude / longitude information in the route information creation system according to the present embodiment will be described with reference to FIGS. In the present embodiment, the description will be made on the assumption that the map information on the ground is a map in which coordinates are expressed by latitude and longitude information.

  When the ground route information registration device 11 is activated, the route information acquisition unit 111 acquires ground map information and registered route information from the ground route information storage unit 22 via the Internet 4. In addition, when performing route registration newly with respect to map information, only the map information on the ground is acquired (step S1).

The route information registration device 1 displays a map expressed by latitude and longitude and the acquired route information on the ground on the route information display unit 112 (step S2). When the mouse is clicked a plurality of times on the displayed map, coordinates based on the latitude and longitude of the clicked point (point specifying information) are stored in the route registration unit 113 as a point sequence.
That is, the operator who performs route registration clicks for each corner from the start point to the end point of the route to be specified (position designation input) with respect to the displayed map information, whereby the route registration unit 113 determines the clicked point, Next, a straight line connecting the clicked point is sequentially registered as a route (step S3).

  On the route information display unit 112, the route information is added by the GUI operation as described above, and the route information is registered with respect to the acquired map information which is inputted by clicking on the displayed map for changing or deleting the route. When is completed, the communication unit 16 transmits the route information stored in the route information registration unit 113 to the ground route information storage unit 22 via the Internet 4 (step S4).

  Next, an operation of registering route information in a map that is not created with a latitude / longitude coordinate expression such as an illustration map in the route information creation system according to the present embodiment will be described with reference to FIGS. . In the present embodiment, description will be made assuming that the map information in the basement / indoor is not a latitude / longitude coordinate representation.

  When the basement / indoor route information registration apparatus 12 is activated by designating an arbitrary basement / indoor area, the route information acquisition unit 121 is designated via the Internet 4 from the basement / indoor route information storage unit 25. Get map information and registered route information. In addition, when newly registering a route with respect to map information, only map information in the basement / indoor is acquired (step S11).

The route information registration device 1 displays a map of the designated area and the acquired route information of the area on the route information display unit 122 (step S12).
The route information registration unit 123 uses a unique coordinate system for the map displayed on the route information display unit 122, with the lower left endpoint of the map being (0, 0) and the upper right endpoint of the map being (100, 100). Define (step S13). In other words, the vertical and horizontal axes are set so that one end is the coordinate origin and the other end is the maximum number of coordinate positions for the vertical and horizontal axes, with the end point on the diagonal line in the map displayed on the screen as the reference. Define the coordinate system specified.

When the mouse is clicked on the displayed map, as shown in FIG. 9 for each clicked point, the route information registration unit 123 acquires the coordinates (point specifying information) in the unique coordinate system described above. And assign a unique ID. This ID is referred to as a point ID, and an underground / indoor area and a point within the area can be specified from the ID.
When the mouse is clicked a plurality of times on the map, a point ID and coordinates in a unique coordinate system are stored in the route information registration unit 123 as a point sequence. That is, the operator who performs route registration clicks on the displayed map information at each corner from the start point to the end point of the route to be designated (position designation input), whereby the route information registration unit 123 determines the clicked point and Then, the straight line connecting the next clicked point is sequentially registered as a route (step S14).

  The route registered by the route information registration device 1 according to the present embodiment is expressed as a series of straight lines connecting such points, and each point has a position ID of the point, for example, an entrance, a stairway entrance, and an elevator entrance. Such point attributes may be stored in association with each other. In addition, by registering the attributes of connection points to other maps, it is possible to connect to the corresponding connection points of the next map from that connection point, and to recognize the route information of the connection across those maps. It becomes like this.

  In addition, route attributes such as ease of walking, distance, presence / absence of steps, presence / absence of Braille guidance, and the like can be associated and registered between the points. By registering such route attributes, for example, guidance for wheelchair users, guidance for visually impaired people, etc., it is possible to perform a search with conditions set during route search.

  On the route information display unit 122, route information is added by the GUI operation as described above, and the route information is registered by clicking on the displayed map to change or delete the route and register the route information for the acquired map information. When is completed, the communication unit 16 transmits the route information stored in the route information registration unit 123 to the underground / indoor route information storage unit 25 via the Internet 4 (step S15).

  Next, in the route information creation system according to the present embodiment, a map created by coordinate expression based on latitude / longitude information and a map not created by latitude / longitude coordinate representation are joined together so as to form a continuous route. The operation will be described with reference to FIGS.

  When an arbitrary underground / indoor area is specified in the ground / underground / indoor joint route information registration device 14 and activated, the route information acquisition unit 141 transmits the ground information from the ground route information storage unit 22 via the Internet 4. Map information and registered route information are acquired, and map information and registered route information of the designated area are acquired from the underground / indoor route information storage unit 25. In addition, when route information is not registered with respect to map information, only map information is acquired (step S21).

  The route information registration device 1 displays a map expressed in latitude and longitude and the acquired route information on the ground on the route information display unit 142 on the ground, and is specified on the route information display unit 143 on the underground / indoor. The map that is not expressed by the latitude and longitude of the area and the route information of the acquired area are displayed (step S22).

When the operator clicks an arbitrary point on the route displayed on the route information display unit 142 on the ground, the coordinates of the clicked point are the point attributes of the connection point with another map, and the connection destination is It is memorize | stored in the route information registration part 144 as a designated connection point in the other map acquired simultaneously.
In addition, when the operator clicks an arbitrary point on the route displayed in the underground / indoor route information display unit 143, the point ID of the clicked point is the point attribute of the connection point with another map. And it is memorize | stored in the route information registration part 144 as a designated connection point in the other map from which the connection destination was acquired simultaneously (step S23).
In this way, the coordinates of the connection point (point identification information), the point attribute, and the connection destination identification information are stored in the route information registration unit 144 as map connection information, so that designation input (click) as the point attribute of the connection point is performed. The two connected points are used as a connecting route, and it is possible to recognize the connected route information across the two acquired maps.

  When the connection route is created by the GUI operation as described above, the communication unit 16 stores the point information that is the point attribute of the connection point stored in the route information registration unit 144 and the connection destination information from the connection point. Is transmitted to the route information storage unit 23 for connecting the ground, underground and indoor via the Internet 4 (step S24).

  In the above-described operation example, it has been described that the map information on the ground and the map information on the underground / indoor are displayed at the same time. However, either one of the map information and the registered route information is first displayed on the display screen and displayed. After a connection point is registered by clicking on the map information, the other map information may be displayed to register the connection point on the map.

  Next, referring to FIG. 12 and FIG. 13, an operation of connecting the maps that are not created with the latitude / longitude coordinate expression so that they can be used as a connected route in the route information creation system according to the present embodiment. explain.

  When two arbitrary underground / indoor areas are designated and activated in the route information registration device 15 for connecting the basement / indoor, the route information acquisition unit 151 via the Internet 4 stores the route information storage unit 25 in the basement / indoor. The map information and registered route information of the two areas designated from the above are acquired. In addition, when route information is not registered with respect to map information, only map information is acquired (step S31).

  The route information registration device 1 displays, on the first underground / indoor route information display unit 152, a map that is not represented by the latitude and longitude of one designated area and the acquired route information, and the second A map that is not expressed by the latitude and longitude of the other designated area and the acquired route information are displayed on the underground / indoor route information display unit 153 (step S32).

When an arbitrary point is clicked on the route displayed in the first underground / indoor route information display unit 152, the point ID of the clicked point is a point attribute of a connection point with another map, and The route information registration unit 154 stores the map as the other map from which the connection destination is acquired at the same time.
When an arbitrary point is clicked on the route displayed in the second underground / indoor route information display unit 153, the point ID of the clicked point is the point attribute of the connection point with another map. In addition, the map is stored in the route information registration unit 154 as another map from which the connection destination is simultaneously acquired (step S33).
Thus, the coordinates of the connection point (point identification information), the point attribute, and the connection destination identification information are stored in the route information registration unit 154 as map connection information, so that the designation input (click) as the point attribute of the connection point is performed. The two connected points are used as a connecting route, and it is possible to recognize the connected route information across the two acquired maps.

  When the connection route is created by the GUI operation as described above, the communication unit 16 stores the point information that is the point attribute of the connection point stored in the route information registration unit 154 and the connection destination information from the connection point. Is transmitted to the connecting route information storage unit 26 between the basement and the interior via the Internet 4 (step S34).

  According to the route information creation system as the present embodiment, route information can be registered to a map as described above, and can be used as map information with route information attached, and the map information can be connected and used. This eliminates the need to place an order with a map data specialist, reduces costs, requires only a simple task, requires little effort and labor, and provides route information with the latest map information including illustration maps. It can be handled, and more detailed real-time update is possible, which can lead to improvement of service such as improvement of maintainability.

  In addition, as described above, route information can be registered simply by clicking on any point on the map displayed on the screen. Therefore, not only the route that can be walked but also the route searcher wants to walk this route. , And can be used for customer guidance in a shopping area or the like.

Next, an operation for making a route search request from the route guidance result display terminal 3 to the route information creation system according to the present embodiment will be described.
First, when the route search request unit 31 shown in FIG. 1 requests the self-position acquisition unit 32 to acquire its own position, the self-position acquisition unit 32 determines its own position from the GPS or the wireless information sign 5 or the like. And returns its own position to the route search requesting unit 31. When the route search request unit 31 requests the destination selection unit 33 to select a destination, the destination selection unit selects the destination and returns the destination to the route search request unit 31. Next, when the route search request unit 31 requests the route search unit 28 via the communication unit 27 (reception means) for the route from the departure point to the destination with its own position as the departure point, the route search unit 28 searches for a route.
Next, the route search unit 28 transmits a route search result to the route search request unit 31 from the communication unit 27 (transmission means) via the Internet 4, and the route search request unit 31 displays the route search result display unit 34. Displays route search results.

Here, the operation when the route guidance result display terminal 3 moves while receiving the route search result will be described.
The self location acquisition unit 32 acquires the current location information of the terminal, and continuously transmits the current location information to the route search unit 28, whereby the map information and the route as the route search result received from the route search unit 28 The route guidance result display unit 34 displays information and current position information. When the current position on the displayed route reaches the connection point of the map, the route search unit 28 sets the ground / underground / indoor joint route information storage unit 23 or the underground / indoor joint route information storage unit 26. The connection destination information is obtained by referring to the map, and the map information is switched to the next map including the connection point registered as the connection destination, and the route information is continuously transmitted.
As a result, the route guidance result display unit 34 continuously displays the map information, route information, and current position information as route search results without any breaks.

  When the route guidance result display terminal 3 has a large screen such as a PC, for example, when entering indoors, for example, when entering indoors, outside map information (map information including latitude / longitude information) and indoor A configuration in which a plurality of pieces of map information to be connected together is displayed at the same time, such as a configuration in which the illustration map is simultaneously displayed.

Next, a route search method in the route information creation system as the present embodiment will be described in detail with reference to the flowchart of FIG.
When a route search is requested from the route search request unit 31, the route search unit 28 acquires the departure point and the destination sent from the route search request unit 31 via the communication unit 27 (receiving means). (Step S41). Next, the range N for acquiring the route information, the maximum range M for acquiring the route information, and the addition value α of the range for acquiring the route information are set, and the ground route information acquisition flag F is set to 0 (step) S42 and S43).

  Next, the route search unit 28 checks whether the departure point is a point on the ground route. Whether the departure point is a point on a ground route or a point on an underground / indoor route is determined by whether the coordinate expression of the departure point is a latitude / longitude or a point ID. If the coordinate expression is latitude and longitude, it is determined as a point on the ground route, and if it is a point ID, it is determined as a point on the underground / indoor route (step S44).

  When the departure point is a point on the ground route, the route information in the range of N centering on the departure point is acquired from the route information storage unit 22 on the ground, converted into a common format for route search, and the route information on the ground is acquired. 1 is set to the flag F (steps S45 and S46). On the other hand, if the departure point is a point on an underground / indoor route, the underground / indoor area to which the departure point belongs is identified from the point ID, and the route information of the area where the departure point exists is stored in the underground / indoor route information storage unit. All are acquired from 25 and converted into a common format for route search (step S47).

  Next, from the ground / underground / indoor joint route information acquisition unit 23 and the basement / indoor joint route information storage unit 26, all joint routes are acquired and converted into a common format for route search. The acquired joining route is investigated to check whether the end points of the joining route exist on all the routes other than the joining route. At this time, the joint route that has already been investigated before is not investigated (step S48).

  If an uninvestigated connection route exists, it is checked whether the connected destination (connection destination) is a ground route. Whether the connected destination is a ground route or an underground / indoor route is determined based on whether the coordinate expression of the connected destination point is latitude / longitude or a point ID. If the coordinate expression is latitude and longitude, it is a ground route, and if it is a point ID, it is determined to be an underground / indoor route (step S49).

  If it is a ground route, it is checked whether the ground route information acquisition flag F is 0 (step S50). When the ground route information acquisition flag F is 0, a route in the range N is obtained from the ground route information storage unit 23 around the connected points and converted into a common format for route search. 1 is set to the route information acquisition flag (steps S51 and S52). On the other hand, when the ground route information acquisition flag F is 1, step S48 is performed again.

  In step S49, if the connected destination is an underground / indoor route, the area where the connected point exists is identified from the point ID, and all the route information of the area is acquired for route search. The common format is converted, and step S48 is performed again (step S53).

  If there is no uninvestigated joint route in step S48, a route search from the departure point to the destination is performed (step S54). It is checked whether or not a route is found. If a route is found, the route search is terminated (step S55). On the other hand, when the route is not found, a value obtained by adding the addition value α to the current route information acquisition range N is newly set to N (step S56).

  Next, it is checked whether or not the range N for acquiring the route information is equal to or less than the maximum range M for acquiring the route information (step S57). When the range N for acquiring the route information is larger than the maximum range M for acquiring the route information, the route search is terminated. If the range N for acquiring the route information is less than or equal to the maximum range M for acquiring the route information, step S43 is performed again.

As described above, according to this embodiment described above, the following effects can be obtained.
The first effect is that a route guidance service in the basement or indoors, which has been delayed due to high map production costs, can be realized at low cost.
The reason is as follows.
The cost of creating a new map can be reduced by using an illustration guide map that has already been created for store guidance and is used for route guidance on a homepage or passage.
The route creation function capable of GUI operation makes it possible to create route information even if it is not a specialist in route information creation, and the route information creation cost can be reduced.

  The second effect is that the route information provision range is expanded by connecting the route information registered for the map information created with different coordinate expressions. For this reason, it is possible to provide a route guidance service that is seamlessly connected not only to the ground but also underground and indoors.

As described above, according to the present embodiment, even if a plurality of pieces of map information include those that can be recognized by latitude and longitude information and those that cannot be recognized by latitude and longitude information, the display screen is displayed. By specifying the connection point on the map, it is possible to register the connection route information across a plurality of maps.
In addition, even if multiple pieces of map information to be connected can be recognized by latitude / longitude information or cannot be recognized by latitude / longitude information, a connection point is specified on the map on the display screen. Thus, it is possible to register route information for a single connection across a plurality of maps.
For this reason, as described above, arbitrary map information including illustration maps can be used for route information registration, and route information can be created at low cost.

In addition, even when there are a plurality of map information that can be recognized by latitude / longitude information and those that cannot be recognized by latitude / longitude information, the route registered for each map information Information and spliced route information can be converted into a common format for route search and handled. For example, even for ground map information and underground / indoor map information, the route information for each map information is restricted. They can be combined freely, and services such as route creation and route guidance can be provided at low cost.
The common format for route search described above may be any format as long as it can express route information and splicing route information.

  In addition, the registration of the point attribute of the connection point can be designated and input by clicking, or can be registered in advance in the map information. For this reason, for example, a person in charge of managing a specific range of map information, for example, a person who is familiar with the specific range registers the location attribute in advance, thereby improving the maintainability of map information and improving the real-time property. Can be planned.

[Second Embodiment]
Next, a route information creation system as a second embodiment of the present invention will be described.

The route search request unit 61 has a function of acquiring a departure point and a destination from the destination selection unit 62 and requesting a route search to the route search unit 28 of the route guidance support apparatus 2 via the Internet 4.
The destination selection unit 62 has a function of selecting a departure point and a destination by receiving a selection input.
The search result storage unit 63 has a function of storing map information and route information as a search result transmitted from the route search unit 28.

Next, an operation of making a route search request from the route information utilization terminal 6 to the route information creation system according to the present embodiment will be described.
First, a user who wants to acquire route information inputs a departure point and a destination from the destination selection unit 62 by selection input or the like. When the destination selection unit 62 transmits the departure point and destination information to the route search request unit 61, the route search request unit 61 sends a route from the departure point to the destination via the communication unit 27 (reception unit). A request is made to the route search unit 28. The route search unit 28 searches for a route by the same operation as the route search operation in the first embodiment described above with reference to FIG.
Next, the route search unit 28 transmits a route search result to the route search request unit 61 from the communication unit 27 (transmission means) via the Internet 4, and the route search request unit 61 sends the route search result to the search result storage unit 63. Map information and route information as a search result are stored.

Note that the second embodiment described above may be configured to include a display unit that displays the search result of the transmitted route, instead of the configuration in which the search result storage unit 63 stores the route search result.
Further, only the destination information may be input by the user from the destination selection unit 62. In this case, the route search unit 28 uses the map information including the destination and the route information from the point where the point attribute of the entrance in the map is registered to the destination as the route search result to the route search request unit 61. Send to.

[About each embodiment]
Moreover, each embodiment mentioned above is a suitable embodiment of this invention, This invention is not limited to this, It can change variously based on the technical idea of this invention, and can be implemented.
For example, in the above-described embodiment, the map information on the ground is described as a map in which coordinates are expressed by latitude and longitude information. However, a map that is not coordinate expressions by latitude and longitude may be used as the map information on the ground. A map created by coordinate expression using latitude and longitude information may be used as underground map information.
That is, the above-described map and the underground / indoor map in the embodiment described above are shown as an example of a map created by a coordinate expression based on latitude / longitude information and a map that is not, and a coordinate expression based on latitude / longitude information. The map is not limited to this as long as it is a map created in and a map that is not.

For this reason, even if an illustration map that is not expressed in latitude and longitude is prepared as ground map information, various processes such as route information registration processing can be performed in the same manner as the underground and indoor map information in the above-described embodiment. .
Also, even if a map expressed in latitude and longitude is prepared as underground / indoor map information, various processes such as a route information registration process can be performed in the same manner as the above-described map information in the embodiment.

Further, when the map information stored in the ground route information storage unit 22 or the underground / indoor route information storage unit 25 is updated, the position ID, coordinates, and point attribute of the registered route information in the map information are updated. Similarly, it is also possible to update only the map information data by setting.
As a result, when only a part of the map is corrected, only the map information can be updated without changing the route information.
Further, when the map information is updated, the position ID and the point attribute in the registered route information may be the same, and an update registration mode in which only the map information and the coordinates can be changed and registered may be provided.

  In addition, for the map information stored in advance in the route information storage unit 22 on the ground and the route information storage unit 25 in the basement / indoor, for example, when the person in charge of each floor is different, the person in charge is assigned for each predetermined range. The person-in-charge information may be defined and each person-in-charge may update the map information and the registered route information.

For map information stored in advance in the route information storage unit 22 on the ground and the route information storage unit 25 in the underground / indoor, only the position of the wireless information sign 5 is registered together with the point attribute of the wireless information sign 5 first.

According to this configuration, it is possible to save the labor for registering point attributes.

In addition, with respect to the map information stored in advance in the route information storage unit 22 on the ground and the route information storage unit 25 in the underground / indoor, for example, when the structure is similar on each floor of the building, The same route information may be registered.
According to this, it is possible to save labor for registering route information for maps having similar arrangements.

In addition, for example, when the person in charge of each floor is different and there is another person in charge of the entire building, the person in charge of updating and registering the location attribute for each map information is separate, and the person in charge of route registration Is stored once in the route information storage unit 22 on the ground or the route information storage unit 25 in the underground / indoor, and by adding / changing / deleting the route again, Each person in charge can proceed with the registration process within the scope of his / her authority.
This allows for flexible registration methods, such as the person responsible for each floor updating map information and registering route information for each floor, and the person responsible for the entire building registering only the location attributes last. It becomes possible to combine.

  Moreover, in each embodiment mentioned above, it demonstrated as acquiring the present position information which added the concept of indoor height (the number of floors) by using the radio | wireless information label | marker 5, However, Indoor height It is not limited to this method as long as the current position information with the concept can be acquired. For example, the route guidance result display terminal 3 includes a gyro motor, and includes various configurations such as a configuration that measures height and a configuration that includes an altitude measuring instrument. It may be a method.

Further, in each of the above-described embodiments, for each of the map information that can be recognized by the latitude / longitude information and the map information that cannot be recognized by the latitude / longitude information, the route information registered for each map information and the connecting route In the route search operation described with reference to FIG. 14, the information is described as being converted into a common format for route search when the route information is acquired. However, when the route search unit 28 performs the route search, As long as it can be handled as a common format, the conversion timing to the common format may be any timing, for example, a configuration for converting to a common format before storing route information and splicing route information, that is, ground route information. A storage unit 22, an above-ground and underground / indoor route information storage unit 23, an underground / indoor route information storage unit 25, and Stitching path information storage 26 between the lower-indoor may be configured to store the converted common format.
Alternatively, the conversion operation to the common format may be performed at another timing in the route search operation.

  In the above-described embodiment, route information is registered via the Internet. However, route information is registered in a stand-alone environment using the route information registration device and the route guidance support device as one route information creation device. It is also possible to do.

  As described above, in the above-described embodiment, the three devices are described as being connected via a network. However, the present invention is not limited to this as long as the functions as the above-described embodiments can be realized. The number of may be arbitrary.

  Moreover, although each apparatus demonstrated as communicating via the internet, as long as it was connected so that communication was possible, it was not limited to the internet, Arbitrary connections, such as various networks, may be sufficient.
