Description

  The present invention enables the user himself / herself to move to a specific location in addition to the user's movement position information by using an information device that can detect the position information, for example, a car navigation system. It is related with the information provision system which can transmit the information which registered and the information which the third party wants to convey.

In various information devices mounted on a moving body, such as a car navigation system, information in the vicinity of the vehicle position captured by the GPS is accessed by accessing an information center, FM character multiplex broadcasting, or CD-ROM, and displayed on a display. Service is realized.
As described above, in the information providing service by the information device currently implemented, the current position of the information device used by the user is specified, and information related to the current position is provided to the user.
For example, in the destination information notification device disclosed in Cited Document 1, destinations (facility) having a large number of vehicle stops are sequentially stored from a traveling history of a predetermined period, and the facility names are ordered in descending order of the number of past stops by category. The position information is taken in. In addition, when displaying information on the destination by category on the display, the facility information is sequentially displayed from the facility where the number of stops of the vehicle in the past is large. Furthermore, instead of the mode in which the facility with a large number of past stops is displayed first on the in-vehicle display device, a mode in which the first facility is preferentially displayed can be performed. If it is a store where the user has not stopped in the past, it is informed that it is the first time, or information on the facility at the position where the vehicle has stopped after the vehicle is stopped is accessed and imported to the information center or CD-ROM. Display information.

  As described above, in the information providing system, specific location information associated with transmission information for which reminding (recalling) is desired is registered in advance, and it is determined whether the corresponding information device has approached the specific location. When an information device approaches a specific location, the information device receives transmission information associated with the specific location, and displays (notifies) the transmission information by displaying it on the display device.

Japanese Patent No. 3264206

By the way, in the conventional information providing system, the time when the transmission information is displayed and notified (remind timing) is within a certain distance from the specific position registered by the information device is set as the remind time. However, the optimum reminder timing differs depending on the contents of the information to be registered.
For example, in the case of notifying an action (ToDo) that should not be forgotten in the living area as transmission information, the following occurs. In other words, when displaying information that must be done during commuting in the living area such as shopping or posting to a post, for example, it reaches a very close position within a display radius of several hundred meters with respect to a specific position, for example. Then display. By setting the display timing as described above, it is desirable to suppress the occurrence of a complicated display screen in which a large amount of display information is displayed on the display screen.

On the other hand, when notifying the transmission information of a place away from the living area, that is, in the case of a restaurant that wants to drop in at an opportunity such as a trip, the determination of the remind timing that it has approached the specific position is several tens to several hundreds km Set to the front. When a specific position is set in a place away from the living area in this way, transmission information is notified early, thereby making it easy to prepare for action and obtaining a desirable display timing.
Thus, it is clear that the optimum timing for notifying the transmission information differs depending on the contents of the registration information. However, without considering this point, the conventional reminder function sets the remind timing to a fixed condition. In the case of Patent Document 1, the same problem is not solved.

  The present invention has been made based on the problems as described above, and the object is to provide an information providing system in which the remind timing for notifying transmission information by an information device can be optimized according to the contents of each transmission information.

The information providing system according to the first embodiment of the present invention will be described below.
FIG. 1 is a schematic diagram showing a configuration of an information providing system according to the present invention.
The information providing system includes a car navigation device (hereinafter abbreviated as “car navigation”) 1 which is an information device mounted on a vehicle on which a user rides, a server 2 for transmitting and receiving information in response to a request from the car navigation 1, A network 3 that connects the car navigation 1 and the server 2 is provided.

Communication of the server 2 is performed via the radio base station 301. That is, data directed from the car navigation 1 to the server 2 is first wirelessly received by the wireless base station 301 and transmitted from the wireless base station 301 to the server 2 via the network 3. Data directed from the server 2 to the car navigation system 1 is transmitted to the car navigation system 1 through the reverse route.
The car navigation 1 according to the present embodiment includes a radio unit 182 having an antenna 181, a communication control unit 183 that controls transmission / reception of the radio unit 182, a position information detection unit (GPS reception unit) 185 having a GPS antenna 184, and a car navigation control unit 110. With. Moreover, the car navigation control unit 110 includes a map information analysis unit 12, a stay history calculation unit 14, an area (notification area) registration unit 15, a movement position determination unit 16, a display control unit 17, a display notification unit 171, Signals are exchanged with each function unit of the operation input unit 172. Further, the car navigation control unit 110 has a function of transmitting / receiving signals to / from each functional unit and transmitting / receiving signals to / from the server 2 via the network.

The radio unit 182 transmits and receives radio waves to and from the radio base station 301. The communication control unit 183 functions as a position information transmission unit, and transmits the current position received by the position information detection unit (GPS reception unit) 185 to the server 2. Further, the communication control unit 183 functions as a request transmission unit, and transmits a navigation request to the server 2. Further, the communication control unit 183 functions as navigation information receiving means, and receives navigation information for the navigation request generated by the navigation information generating unit 211 on the server 2 side.
A position information detecting unit (GPS receiving unit) 185 of the car navigation 1 constitutes position information detecting means for receiving the position information from the GPS receiving unit 185 and measuring the current position. The map information analysis unit 12 analyzes the map information sent from the server 2 and performs a process of entering the position of the own station.

The operation input unit (operation panel) 172 is also a registration unit, and includes a plurality of operation keys such as an on-hook key, an off-hook key, and a numeric keypad. Each operation key consists of a contact opening / closing type switch having a pressing surface. By pressing the pressing surface, the terminals are connected to each other to output a predetermined input signal, and a registration command is also input. Yes. The display notification unit 171 has a function as a notification unit, and is configured by, for example, a liquid crystal display that performs a display notification operation according to a display command of the display control unit 17.
The display control unit 17 controls various display operations of the car navigation 1. For example, the map information and route information acquired from the server 2 are displayed on the display notification unit 171, or the map information displayed on the display notification unit 171 is displayed based on the user's operation on the operation input unit (operation panel) 172. Change the image. In particular, it functions as a notification means for notifying that a vehicle has approached an arbitrary point when the vehicle enters a later-described notification area (inside the R radius garden).

The area (notification area) changing means 15 on the car navigation 1 side registers instruction information to the operation input unit (operation panel) when the user registers and changes an arbitrary point (remind position) rp (see FIG. 6) of the map data. ) 172 is used to instruct the notification area registration unit 213 as registration means on the server 2 side to register in the database 4.
The moving position determination means 16, which is a position determination means on the car navigation 1 side, detects the position information Pm (see FIG. 6) of the car navigation 1 (information device), and the vehicle equipped with the car navigation 1 is detected in the unit section u (FIGS. 2 and 6). Enter) and determine whether or not to stay.

  The stay history calculation unit 14 on the car navigation 1 side functions as a means for calculating and updating the stay history. Here, the stay time Pt when the vehicle equipped with the car navigation system 1 stays in the information storage unit UM (see FIG. 5) of the unit section u (see FIGS. 2 and 6) and the accumulation point Pf based on the stay frequency are calculated. These data A and B are transmitted to the stay history accumulation unit 6 of the server 2, where they are accumulated in the storage medium M. The server 2 may have the stay history calculation unit 14, and the server may calculate and store the stay time of the unit section and the accumulation points based on the stay frequency. As a result, the car navigation system 1 can reduce the memory capacity for storing the computation load and the history only by sequentially transmitting the current location information to the server 2.

On the other hand, the server 2 is connected to the radio base station 301 via the network 3 that is an information transmission network, and communicates with the car navigation system 1 via the radio base station 301.
The server 2 is an external server, and the information transmission / reception unit 21 that is a communication control unit included in the server 2 controls communication with the car navigation system 1. The information transmitting / receiving unit 21 has functions as position information receiving means, request receiving means, and navigation information transmitting means. The information transmission / reception unit 21 receives information on the current position of the vehicle equipped with the car navigation 1 as position information receiving means. The information transmitting / receiving unit 21 receives a navigation request from the car navigation 1 as a request receiving unit. The information transmission / reception unit 21 transmits navigation information corresponding to the navigation request to the car navigation 1 as navigation information transmission means. The information transmission / reception unit 21 exchanges signals with each functional unit of the server 2 via the server control unit 210.

Here, the database 4 of the server 2 stores nationwide map information that defines a large number of roads, position information acquired from the car navigation 1, and route information for which there has been a navigation request from the car navigation 1. Further, the database 4 forms a memory storage unit for a reminder function.
Reminded information (spot information stored in association with the reminded position (registered spot) when the car navigation 1 approaches a registered position (reminded position registered by the user as an arbitrary point of the map data) rp (see FIG. 6). ) Is transmitted to the car navigation 1 and displayed.
Here, the server control unit 210 exchanges signals among the navigation information generation unit 211, the location route search unit 212, the notification area registration unit 213, the stay history update accumulation control unit 214, and the database 4.

The position route search unit 212 forms a road discrimination function unit, and discriminates the road where the car navigation 1 is located based on the map information and the position information of the car navigation 1.
The navigation information generation unit 211 generates navigation information including the route information and map information obtained by the position route search unit 212. Specifically, the navigation information generation unit 211 generates only the destination for which the navigation request is received from the car navigation 1 as navigation information, generates only route information as navigation information, or only map information as navigation information. Or generate.
Further, when the user registers an arbitrary point (remind position) in the map data, when the user inputs a registration instruction from the operation input unit (which is also a registration means) 172, the notification area registration unit 213 receives the registration instruction signal ( Remind position information) is sent to the action history storage unit 5.

Here, as will be described later, the action history accumulating unit 5 in the database 4 presets a mesh U (also referred to as a unit block in some cases) U that is a plurality of unit blocks in advance by dividing the entire area of Japan into a mesh shape. Amnestic processing.
The action history storage unit 5 adds the reminder information (point information (remind position)) to the corresponding unit section u of the storage medium M and the information storage section UM (see FIG. 5) in the unit section u, and the existing information that the server 2 has. And related spot information arbitrarily input by the user).
The stay history update accumulation control unit 214 newly calculates the stay time Pt for which the car navigation system 1 stays in the information accumulation unit UM (see FIG. 5) of the unit section u, or the accumulated point number Pf based on the stay frequency, by the position determination means 16. Each time it is updated, it is updated and stored as new registration information.

  Here, the reference point of the unit section u to which the registered reminding position belongs is used as the reminding position rp. After that, the accumulation point number Pf in the unit section u having the reference point rp which is the remind position is read out. If this value is a remote place, for example, the stay time Pt and the accumulated point number Pf corresponding to the stay frequency are set small, and the notification area (remind area radius R1) with respect to the reference point rp is set large. This is because the reminder area radius R1 is set to be large when the number of accumulated points Pf is small, and when moving to a remote place, the recognition of the information set at the remote place is accelerated, and the information is effectively used. On the contrary, if the staying time Pt or the accumulated point number Pf corresponding to the stay frequency is large and the area stays frequently, the area of the notification area (remind area radius R1) with respect to the reference point rp is set to be small, and unnecessary display is suppressed. I am doing so.

  In the server 2, the action history accumulation unit 5 accumulates specific map data for an area specified in advance, for example, the entire area of Japan used here. Further, here, a mesh U (also referred to as a unit block in some cases) U that is a plurality of unit blocks is set by dividing the entire map area of the specific map into a mesh shape. A storage medium M is arranged opposite to the action history storage unit 5, and a large number of information storage units UM associated with the mesh u are provided on the storage medium M and function as a part of the action history storage unit 5. Furthermore, the stay history accumulation unit 6 is disposed opposite to the action history accumulation unit 5 with the storage medium M interposed therebetween. Here, a large number of information storage units UM of the storage medium M share a mesh (unit section) U having the same position information as the stay history storage unit 6, and the information storage unit UM of each mesh (unit section) U Connected to allow data storage.

Here, by dividing a map representing the entire region of Japan as specific map data into a mesh shape having a predetermined width, for example, 1 km2, mesh u which is a plurality of unit sections as shown in FIGS. Set division. In association with this, on the storage medium M, each information storage unit UM of a large number of meshes u is arranged as an aggregate.
In each information storage unit UM of the storage medium M, values Pt and Pf obtained by scoring the time and stay frequency at which the car navigation system 1 stays in the mesh u, which is a unit partition, are updated and stored.
For example, as shown in FIGS. 2 and 5, a storage area for the accumulation time value Pt is set in the left area of the information accumulation unit UM. Further, as shown in the map m1 in FIG. 3, the time that the car navigation system 1 stayed for each week is totaled for each mesh u, ranked according to the size of the total time, and the accumulated time value Pt is updated. sign up. Here, the symbols A ·· F are given in order from the largest accumulation time value Pt, and an example of the code distribution is shown in FIG.

Further, as shown in FIGS. 2 and 5, a storage area for the stay frequency point value Pf is set in the right area of the information storage unit UM. Here, as shown in a map m2 in FIG. 4, the number of days visited every year in each mesh u is totaled. Furthermore, the ranking is given according to the size of the aggregation date value, and the stay frequency value Pf is set. Furthermore, the symbols A ·· F are given in order from the larger stay frequency value Pf, and the symbols are shown in FIG.
In FIG. 2, the symbol of the information storage unit UM is A.3. A and A. B and B. A mesh u described as A represents a user's living area with a large staying frequency and staying frequency of the user. F. F or F. E and E. A mesh u described as F represents a far place for a user far away from the user's living area.

Next, the stay history accumulating unit 6 constituting the main part of the notifying means here shares the action history accumulating unit 5 and the information accumulating unit UM of each mesh u. FIG. 5 is an enlarged view of one of the meshes u shown in FIG. As shown in the enlarged mesh u, the information storage unit UM of the mesh u stores the position information rp of each point (reminded position) and the accumulated time value of the user's stay time for which the action history storage unit 5 updates the stored data. Write areas O, A, and B for Pt and stay frequency value Pf are secured.
Further, in the upper area of the storage area of the left and right accumulation point values Pt and Pf of the information accumulation unit UM, the spot information sj that the user desires to be reminded and the remind position that is the point (reference position) for calling the spot information sj A write storage area for information Prp and a reminding area radius R1 information with the reminding position rp as a base point is secured.

  The spot information sj that the user desires to be reminded includes facility information of various facilities such as a post office, a bank, a restaurant, etc., and these are written and set by the user. That is, the point (remind position) rp is input by the operation input 172 as registration means, and is written and set together with the facility information for calling the spot information sj associated with the information. The reminding area radius R1 is set around the reminding position rp. At this time, the region (notification area) registration means 15 reads the user accumulated time value Pt and the stay frequency value Pf (see FIGS. 2 to 4) in the mesh u having the remind position rp, and the user's stay time and frequency value equivalent. A reminder area radius R1 having a length corresponding to the storage time value Pt and the stay frequency value Pf is set.

The stay history accumulating unit 6 also has a function as a region changing means. The smaller the accumulated point value Pf of the mesh u (unit section) including the reference point (remind position rp), the smaller the accumulated point value Pf, the more remote the site is considered. A function for greatly changing the notification area (remind area radius R1) according to the remind position (rp) is provided. In other words, the range (remind area radius R1) calculated based on the accumulation point values Pt and Pf is registered and updated in the information accumulation unit UM that forms the registration area of the mesh u.
Here, in order to calculate the remind area radius R1, the radius a, b,.

From the information storage unit UM that forms the registration spot, the sum of the storage points Pt and Pf of the mesh u located within the radius a, the sum of the points of the meshes within the radius ab,
The weight coefficients ka, kb,... (Ka>kb>...) Are multiplied to calculate the sum of the reciprocals as shown in the equation (1), and the reminding area radius R1 is calculated.
Assuming that meshes 1 to m exist in the reminding area radius R1, and meshes m + 1 to n,... Exist in the radii a and b, the reminding area radius R1 is calculated by the equation (1).
R1 = 1 ÷ {ka × (Pt ₍₁₎ + Pt ₍₂₎ + ... + Pt _(m) + Pf ₍₁₎ + Pf ₍₂₎ + ... + Pf _(m) )} +
1 ÷ {kb × (Pt _{(m + 1)} + Pt _{(m + 2)} + ... + Pt _(n) + Pf _{(m + 1)} + Pf _{(m + 2)} + ... + Pf _(n) )} + ... (1)
Where ka: (weighting factor within radius a, Pt _{(1) to} Pt _{(m) to} Pt _(n) : points of staying time for each mesh)
kb: (weighting factor within radius ab, Pf _{(1) to} Pf _{(m) to} Pf _(n) : score of stay frequency for each mesh)
FIG. 6 shows a plurality of reminding area radii R1 which are concentric circles.

Next, the operation of the information providing system in FIG. 1 and the car navigation 1 that is the information device will be described with reference to the information providing flowchart in FIG.
In the information provision processing routine performed by the control means of the car navigation 1, it is assumed that steps s1 and s2 are reached in response to turning on of the vehicle.
Here, the current position Pm (see FIG. 6) of the vehicle (user) mounted on the car navigation 1 is detected by the position information detecting means (GPS) 185.
Further, the staying time, the staying time equivalent storage time value Pt and staying frequency value Pf at the mesh u where the user is currently located are used as the storage time value conversion map m1 in FIG. 3 and the storage point value conversion map m2 in FIG. To calculate.

Here, the calculated accumulation point value pt is transmitted to the action history accumulation unit (in the database 4) 5, and the value of the corresponding information accumulation unit UM corresponding to the mesh u is updated. Further, the calculated stay frequency value Pf is transmitted to the stay history storage unit (in the database 4) 6 to update the value of the corresponding information storage unit UM corresponding to the mesh u.
As described above, the accumulation time value Pt, the stay frequency value Pf, and the point (remind position) information Prp of the vehicle equipped with information equipment (car navigation system 1) are periodically accumulated in the action history accumulation unit 5, and the vehicle (user) Know the scope of action. Further, by updating the value of the information storage unit UM, it can be used to determine the notification timing (set by the reminding area radius R1 at the reminding timing) from the normal user action range described later.

Next, in step s3, the presence of a remind position rp (position associated with spot information sj) in the circle s1 centered on the current position Pm (see the lower right area in FIG. 6) of the vehicle (user) mounted on the car navigation 1 is determined. to decide. At this time, the reminder region radius R2 (remind range calculation radius) at the center of the user (Pm position) is sequentially expanded, and the reminder position rp registered in the action history storage unit (in the database 4) 5 (see the lower left region in FIG. 6). ). When the remind position r0 is in the circle s2 having the maximum radius, the process proceeds to step s4. Here, the reminder area radius R2 which is the radius detected this time is updated as the current value, and the current reminder area radius R2 is updated and registered in the stay history accumulation unit 6.
Thereby, the timing of notification is determined from the action range of the vehicle (user) equipped with the usual car navigation system 1.

Next, assume that step s5 is reached. Here, the setting data of the reminding area radius R1 centered on the reminding position rp (position where the spot information sj such as the facility is located) is fetched from the stay history accumulating unit 6, and the formula (1) is used according to these data. Then, the reminding area radius R1 is calculated. Then, it is determined whether or not the current position of the vehicle (user) mounted on the car navigation 1 exists within the remind area radius R1, that is, whether or not there is a remind position rp (position where spot information sj is present).
Otherwise, in step s8, if there is, in step s6, the remind flag at the remind position rp (position where spot information sj is present) is turned on, and the process proceeds to step s7. Here, the display control unit 17 of the car navigation 1 functions to provide the user with the spot information sj of the remind position rp, receives the spot information sj called from the stay history storage unit 6, and displays the display notification unit 171. To display (remind display).

  Next, when the process reaches step s8, the process reaches the position where the remind flag is switched off (OFF), and it is determined whether or not the user has gone out of the remind area radius R1 and a predetermined time has passed. After the elapse, the process proceeds to step s9. Here, the remind flag at the remind position rp (position where the spot information sj is present) is turned off, and the current control cycle is ended.

Thus, in this information provision system, the point information Prp of the mesh u where the car navigation 1 of the vehicle operated by the user stays is obtained. Further, the storage time value Pt and the stay frequency value Pf of the user are calculated, and the storage point values of the information storage unit UM of the stayed mesh u are added and updated by the storage point values Pt and Pf corresponding to the calculated values. deep. Then, for each mesh u including the remind position rp associated with the spot information sj, a remind area radius R1 having a length corresponding to the accumulation point values Pt and Pf is set.
Then, when it is detected that the car navigation 1 stays in the mesh u within the reminding area radius R1, the stay history accumulating unit 6 calls the spot information sj associated with the reminding position rp and displays it by the function of the display control unit 17 Displayed on the notification unit 171. At this time, in particular, when the car navigation system 1 displays information, the reminding area radius R1 is adjusted according to the accumulation point value Pt and Pf corresponding to the accumulation time value Pt and the stay frequency value Pf of the mesh u. Inappropriate display can be suppressed.

As described above, when the car navigation 1 displays information, the reminding area radius R1 is adjusted according to the accumulated point values Pt and Pf according to the stay time and stay frequency of the mesh u. The reminding area radius R1 may be adjusted by the accumulation point value corresponding to only one of them to simplify the configuration.
Further, in the above description, the information device operated by the user of the vehicle equipped with the car navigation 1 is the car navigation 1, but instead of this, as a second embodiment, the information device is a personal computer (not shown) mounted on the vehicle. It may be comprised. Also in this case, a personal computer as an information device is connected to the server side using a communication means that enables transmission and reception with a wireless base station of the network, and can perform the same function as in the first embodiment. The effect is obtained.
Furthermore, although the notification area is circular as described above, the notification area is not limited to this, and may be, for example, a triangle, a quadrangle, or a polygon.

  Further, in the above description, the information device operated by the user of the vehicle equipped with the car navigation 1 is the car navigation 1, but instead, as the third embodiment, when the information device is driven, the user brings it into the vehicle. It is good also as a portable terminal. Specifically, the information device is composed of, for example, a smartphone. Moreover, since the screen of a portable terminal is generally small and not suitable for viewing during driving, a combination of a portable terminal and an in-vehicle display may be used. By using the portable terminal that the user brings in, the user can register the remind position at any time without being in the car. For example, if you register a shop introduced as a reminder when watching TV at home, or work at a company, or if you receive a shopping request when you go home by email from a family member, It is possible to register a supermarket as a reminder position.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
