Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a navigation device, a server, a position history data output method, and a program.

[0002]

2. Description of the Related Art In recent years, GPS (Global
Positioning System (Global Positioning System) A navigation device that can obtain its own position and moving speed in real time using a satellite is becoming widespread for mounting on a mobile body such as an automobile or for portable use. In the navigation device, the map is displayed on the monitor based on the digitized map data. Further, the position data of its own position measured using GPS satellites is stored at predetermined intervals (time or distance), and the stored position data is plotted as a locus point, etc. It can also be displayed on top of.

By the way, in recent years, portable telephone terminals and PDAs
Even portable information terminals such as (Personal Digital Assistant) can acquire location information by communicating with an external server. Thus, it is possible to grasp where the user carrying the portable information terminal or the vehicle equipped with the portable information terminal is at present by plotting it on a map using a personal computer or the like.

[0004]

However, in the case of a navigation device mounted on a moving body, the locus point merely indicates the point where the user has passed. Therefore, when the locus point displayed on the map is referred to, the travel route is simply known on the map, and it is not possible to specifically obtain information such as the place name of the visited point or the frequency of the visit. Also,
The number of locus points held in the navigation device is determined in consideration of the memory capacity and the like, and when the number exceeds a predetermined number, the locus points in the history are deleted sequentially.

Further, the position information can be obtained using the portable information terminal is limited to the latest position information, and the user carrying the portable information terminal or the vehicle equipped with the portable information terminal. There is no information provision form that provides the past location information history of when and where.
Therefore, by editing the past location information history data, the behavior history of the user or the vehicle equipped with the portable information terminal, such as the area where the user or the vehicle equipped with the portable information terminal frequently visits, the number of visits, etc. There is no service that provides information. The present invention is based on a new idea of effectively utilizing past position information history, and provides a navigation device, a server, a position history data output method, and the like that can easily and easily grasp an action history. The purpose is to

[0006]

Based on the above object, the navigation device of the present invention classifies position data into any of a plurality of preset areas and generates movement history information based on the areas. Is characterized by. More specifically, when the position data acquisition unit acquires position data, the position data classification processing unit classifies the position data into any of a plurality of preset areas. Then, the history information output unit outputs the movement history information generated by the history information generation unit based on the area. Here, the area is
The area can be set using administrative divisions such as prefectures, municipalities, town names, etc. that have a range of predetermined position data. The movement history information may include the number of entries to the area (the number of times the area has been entered), the frequency of visits to the area, the length of stay in the area, and the like. Further, in the navigation device of the present invention, movement history information may be added to the map and displayed.

In the server of the present invention, the position data receiving section first receives the position data transmitted from the external position data acquisition terminal via the network. In response to this,
The area specifying unit specifies an area to which the position data belongs, out of the plurality of areas each having a predetermined range set therein. Then, the history information control unit generates and outputs the movement history information for each area of the position data acquisition terminal based on the plurality of position data in which the area to which the history information control unit belongs is specified.
Here, as the position data acquisition terminal, there is, for example, a navigation device, and a portable telephone terminal or PDA (Person).
A portable information terminal such as al Digital Assistant) may be used as the position data acquisition terminal. In addition, the history information control unit can transmit the movement history information via the network to an external history display terminal that displays the movement history information. As the history display terminal, a navigation device, a mobile phone terminal, a PDA (Personal Digital Assis
In addition to a portable information terminal such as a tant), a personal computer of the user can be used. Further, the history display terminal may be the same as the position data acquisition terminal. That is, the position data may be transmitted from the navigation device or the portable information terminal to the server, and the movement history information generated by the server may be received by the navigation device or the portable information terminal that transmitted the position data. Further, the position data may be transmitted from the navigation device or the portable information terminal to the server, and the movement history information generated by the server may be received by another personal computer. Strictly speaking, it is possible that the exchange of the portable information terminal specifies the position of the portable information terminal and the exchange and the server communicate with each other to obtain the position data of the portable information terminal. Also in this case, it can be said that the position data is acquired from the portable information terminal in a sense. Therefore, the "position data transmitted from the position data acquisition terminal" in the present invention includes the position data transmitted from the exchange of the portable information terminal.

In the position history data output method of the present invention, when the position data is acquired, the area to which the position data belongs is detected. Then, the number of entries into the area is counted based on the detection result of the area. Next, position history data including the number of entries is generated and output. It should be noted that the position history data may include data other than the number of entries, such as the time spent in the area and the date and time when the user entered the area. Furthermore, the present invention can be provided as a program that causes a computer device to execute processing corresponding to each step in the above-described position history data output method.

By the way, the navigation device of the present embodiment accumulates position information history data, edits this data in a format according to an instruction from the user, and stores it as history data (movement history information, position history data). It is displayed on the display unit 15. In order to realize such a configuration, the control block 17 controls the drawing on the display unit 15 by a display control unit (history information output unit) 38, positioning data (position data).
A history setting control unit 39 is further provided for detecting an area and controlling an area counter based on the above, and for generating and outputting history data based on an instruction from the user. Here, the area is set by previously dividing the map based on the map data stored in the recording disk into a plurality of areas, and each divided area is defined as one area. Areas are set, for example, in a plurality of upper and lower layers having different sizes (areas) of areas, and the areas can be set using administrative divisions such as prefectures, municipalities, and town names.

FIG. 2 shows the configuration of the history setting control unit 39. The history setting control unit 39 uses the area number information storage unit 4
0, area number detection unit (position data classification processing unit) 41,
A current area number storage unit 42, a count control unit (entry number counting unit) 43, an area counter 44, and a history display execution unit (history information generation unit, history information output unit, entry number counting unit) 45 are provided. The area number information storage unit 40 stores an area number as information for identifying each area. The area number is added, for example, by prefecture, municipality, or town name. As mentioned above
An area is composed of a plurality of layers associated with each other, and correspondingly, an area number is also composed of a plurality of layers associated with each other. In other words, Hokkaido = A1, Aomori = A
2. Area numbers by municipalities are added as lower layers of the area numbers by prefectures added such as 2, Tokyo = A15, Okinawa = A47. For example, there are cities such as Hachioji City and Tama City and 23 wards of Tokyo as a lower hierarchy of Tokyo = A15, and as shown in FIG. 3, Chiyoda ward = A15-1, Chuo ward = A15-2, Minato ward = A15. -3, Shinjuku-ku = A15
Area numbers by municipalities are added such as -4. Further, the area numbers by town name can be added as a lower hierarchy of these area numbers by municipality, for example, Kabukicho = A15 as a lower hierarchy of Shinjuku-ku = A15-4.
-4-1, Shinjuku 3-chome = A15-4-2, and the area number is added. The area number does not necessarily have to be alphanumeric and may be identification information added to identify the area. Area number information storage unit 40
Holds the range of position data corresponding to each prefecture, municipality, and town name to which the area number is added.
For the range of position data, for example, latitude / longitude information and position coordinates can be used. The area number and the range of position data of each area are stored in association with each other.

The area number detecting section 41 is a GPS positioning section 2
The area number is detected based on the positioning data of 2 and the information stored in the area number information storage unit 40 described above. As described above, the area number has a plurality of hierarchical structures, but the area number detection unit 41 detects the area number of the lowest layer. This is the area number of the lowest layer (eg
This is because Kabukicho = A15-4-1) contains more detailed information than the higher area numbers (for example, Shinjuku-ku = A15-4, Tokyo = A15). The timing at which the area number detection unit 41 detects the area number can be set every time a predetermined time elapses or every predetermined distance traveled. The area number detection unit 41 also includes a current area number storage unit 42. The current area number storage unit 42 holds the area number detected immediately before by the area number detection unit 41. The area number detection unit 41 compares the detected area number with the current area number stored in the current area number storage unit 42. If the detected area number is different from the current area number, the current area number is appropriately changed. Rewrite the area number.

The count controller 43 includes an area counter 44.
The count controller 43 controls the area counter 44 based on an instruction from the area number detector 41. Here, as shown in FIG. 4, the area counters 44 exist for each area number, that is, for each area number. Therefore, for example, there are area counters 44 corresponding to respective prefectures, municipalities, and town names. In the area counter 44, a count value (movement history information, position history data) C indicating the number of visits (entry number) to each area to which an area number is added as shown in FIG. 4, and when each area is visited Time information (movement history information, position history data) T indicating whether or not it is stored is also stored. That is, when the current area number stored in the current area number storage unit 42 is rewritten, the count control unit 43 counts the count value C of the rewritten area number (the area number that has become the new current area number).
Rewrite. Then, the time information T when the current area number is rewritten is stored. The time information T is generated based on the time information acquired by the clock unit (not shown) that acquires the time information included in the GPS signal or the standard radio wave.

The history display execution unit 45 generates history data based on a history display instruction from the user, and outputs the history data to the display unit 15 in cooperation with the display control unit 38. Here, as the contents of the history display instruction, for example, "unit of area where history is to be displayed", "period for which history is to be counted", and "history data output form" can be mentioned. That is, when the user gives a history display instruction to the navigation device, by prefecture, by city, by town name, etc.
It is possible to arbitrarily specify the "unit of the area where the history is to be displayed". In addition, the user arbitrarily specifies the “history for which the history is to be counted”, for example, only on a specified day, the past one month, the past three months, the past one year, or the entire period after the start of using the navigation device. can do. The history display executing unit 45 acquires the count value C in the area counter 44 based on the unit of the area for which the history is to be displayed and the period for which the history is to be counted, which is designated by the user, and displays the count value C on the display unit 15. Output to. The user can also arbitrarily select the output form, that is, the “output form of history data”. For example, only character information (area number, count value C, etc. are output as text information), count value C is added on the map (count value C is added to the area on the map corresponding to the area number), and count value C is added. Depending on the situation, display effects such as coloring are added to the map (areas on the map corresponding to the area numbers are displayed in different colors according to the count value C), and the output form of the history data is appropriately selected. You can

The display controller 38 includes a graphic controller and a video RAM. The graphic controller reads image data such as a map from the disk drive 13 based on the instruction from the history display execution unit 45 described above. For example, if the unit of the area for which the history designated by the user is classified by prefecture is a national map of Japan, and if the unit of the area for which the history designated by the user is 23 wards of Tokyo is 23 wards of Tokyo. The map including is read from the disk drive 13. Then, the graphic controller expands and stores the image data of the map or the like read from the disk drive 13 in the video RAM with the history data generated by the history display executing unit 45 added thereto, for example, as shown in FIG. The image data such as a map stored in the RAM is displayed on the display unit 15. In the navigation device having such a configuration, the number of visits to the area can be totaled and the result can be displayed on the display unit 15.

FIG. 5 is a diagram showing the flow of processing when the history setting control unit 39 counts the number of visits to the user's area and outputs it to the display unit 15. In addition, in order to simplify the description, in the present embodiment, the following description will be given on the assumption that the area numbers by municipalities are the lowest layer area numbers. The process shown in FIG. 5 is automatically executed while the navigation device is running.

First, in step S101, the GPS
The position of the user is measured by the positioning unit 22. In the following step S102, the area number detection unit 41 displays G
The area number is detected based on the positioning data by the PS positioning unit 22. Here, as shown in FIG. 3, it is assumed that the GPS positioning unit 22 detects the position of the user at the point a in Ota Ward. Then, the area number detection unit 41 refers to this positioning data and the information (area number, range of position data) stored in the area number information storage unit 40, and the area number corresponding to the point a is A15-11. Is detected. In step S103, the area number detection unit 41
Area number detected in step S102 (A15-
11) is compared with the current area number stored in the current area number storage unit 42. If the current area number matches the area number (A15-11) detected in step S102, step S1
Proceed to 06. That is, when the detected area number and the current area number match, the area number detection unit 41 does not rewrite the current area number, and the area number stored in the current area number storage unit 42 ( A15-11) is continuously used as the current area number.

On the other hand, if it is determined in step S103 that the detected area number and the current area number do not match, the process proceeds to step S104. As a specific example, in the state where the current area number is A15-11, the user moves from point a in Ota Ward (area number: A15-11) shown in FIG. 3 to point b in Setagaya Ward (area number: A15-). If the area number is changed by moving to 12), it is determined as "mismatch" in step S103. In subsequent step S104, the area number detection unit 41 stores the newly detected area number in the current area number storage unit 42 as the current area number. Explaining in the above example, the current area number is rewritten from A15-11 to A15-12.

In step S105, the count controller 4
3 is the count value C of the area counter 44 of the area number newly detected in response to the instruction from the area number detection unit 41 (the area number that has become the new current area number).
"1" is added to (hereinafter, appropriately abbreviated as "count value C"). For example, as shown in FIG. 4, when the count value C of Setagaya Ward (area number: A15-12) is “17”, the count control unit 43 adds “1” to “17”. The count value C is set to "18". Thus, only when the detected area number and the current area number are determined to be “mismatch”, that is, when the user moves beyond the area, the count value C
Is added.

In step S106, the input control unit 34 determines whether or not there is a history display instruction. Here, if it is determined that there is no history display instruction, the process proceeds to step S109. On the other hand, if it is determined in step S106 that there is a history display instruction, the input control unit 34 indicates that there is a history display instruction and the content of the history display instruction, that is, the unit of the area in which the history designated by the user is to be displayed ( The history display execution unit 45 is notified of each prefecture, each city, town name, etc.), the period for which the history should be counted, the output form of the history data, and the like.

In the subsequent step S107, the history display executing section 45 causes the input control section 34 in the step S106.
The history data is generated based on the notification from. That is,
The count value C and time information T in the area counter 44
With reference to, the count value C within a predetermined period is totaled. Here, the unit in which the user should display the history is 23 wards in Tokyo, and the period in which the history is to be counted is the past 3 months (for example, 2001
January 1st to March 30th, 2001). In this case, the history display execution unit 45 extracts only the ones having the time information T within the past three months from the area counter 44 in the 23 wards of Tokyo and counts the count value C. Therefore, for example, even if there is data of December 1, 2000 as the time information T of Setagaya Ward (area number: A15-12), this data is excluded when generating the history data in step S107. Becomes

When the history data is generated in step S107, the history data is sent to the display controller 38. Then, in subsequent step S108, the history data is output to the display unit 15. Here, it is assumed that the user has selected the form of adding the count value C on the map as the output form of the history data. In this case, the graphic controller reads a map of a predetermined area from the disk drive 13, for example, a map including the 23 wards of Tokyo, and adds history data, that is, the number of visits of the user for the 23 wards of Tokyo, to the map. It is output to the display unit 15 as shown in FIG. Further, when the user has selected a display form in which a display effect such as coloring is added to the map according to the count value C as the output form of the history data, each region (area number) of the map shown in FIG. It is also possible to display history data by coloring (range of position data corresponding to) according to the number of visits. For example, when the number of visits is "0", it is white, when it is "1" to "9", it is green,
"10" to "19" is blue, "20" to "29" is yellow, "30" to "39" is orange, and "40" or more is red. Color display may be provided so that the visit situation to the area can be easily recognized. In addition, without using the map or in combination with the map display, for example, “45” in Shinjuku Ward, “4” in Minato Ward
A list listing the contents such as “0” and Shibuya-ku “35” can be output to the display unit 15. Alternatively, the history data may be output by voice through the speaker 11.

In step S109, the input control unit 34 determines whether or not there is an area number detection clear request. For example, the area number detection clear request is automatically generated when the navigation device is powered off or the date is changed. When it is determined to be “Yes” in step S109, the input control unit 34 notifies the area number detection unit 41 that there is an area number detection clear request, and proceeds to step S110. On the other hand, if the determination is “No” in step S109, the process ends. In step S110, the area number detection unit 41 stops the area number detection, clears the current area number stored in the current area number storage unit 42, and ends the processing.

As described above, for example, area numbers are added by prefecture, municipality, and town name, the number of visits to the area is calculated, and the result is output. Accordingly, the user can easily and easily grasp the action history within the predetermined period without performing the operation of sequentially recording the visited area, the place where the vehicle has passed, and the like. There are various possible uses of the history data generated by the history setting control unit 39. For example, history data may be output to the outside via the communication unit 37, and the history data may be used as part of management of company cars. Alternatively, the history data may be transmitted to an external server via the communication unit 37 so that information related to an area that is frequently visited is provided. As described above, according to the navigation device described above, the past position information history can be effectively utilized, and thus the user can use the navigation device for purposes other than route guidance to the destination. .

In the first embodiment, the area numbers by municipalities are as lower layers of the area numbers by prefectures, and the area numbers by town names are as lower layers of the area numbers by municipalities. Although the example of adding the area number having the three-layer structure is shown, these are merely examples, and the area number may be composed of more layers or less layers. Also, by prefecture, by municipality,
The area number may be added to an arbitrary area or arbitrary point, not limited to each town name. Further, in the above-described embodiment, the history data in the 23 wards of Tokyo is generated and displayed on the display unit 15. However, the unit in which the history is to be displayed is in a wider range, such as the entire Kanto region or prefectures. The same processing is performed when set, or when the unit whose history is to be displayed is set to a narrower range such as Setagaya Ward.

The map stored by the navigation device is not limited to prefectures or municipalities, but is divided into meshes at a certain scale. Navigation device is G
When the position of the user's own position is measured by the PS positioning unit 22, a search is made as to which map is included in the map divided into a plurality of meshes, and the user's map is displayed on the map including the point. Plot your position and present it to the user.
By utilizing this, it is also possible to set the area for displaying the history so as to match with the map divided into a mesh shape and display the history information according to this.

[Second Embodiment] In a second embodiment described next, the position information of the portable information terminal and the position information thereof are detected by cooperation between the portable information terminal and the wireless base station. Get time information when Then, the acquired position information and time information are transmitted from the portable information terminal to the external server and stored therein, and the external server transmits history data, that is, the number of times the user has visited the area to the user terminal in response to a request from the user.

Next, FIG. 9 shows a processing flow when the server 60 generates history data and transmits it to the user terminal 70. In this process, the user performs a predetermined operation for requesting history display on the user terminal 70, and in response to this, the server 60 executes the process. First, step S301
In, when the user performs a predetermined operation for requesting history display on the user terminal 70, a history display request message is generated and transmitted to the server 60. In the history display request message, the unit of the area for which the history is to be displayed (by prefecture, by city, by town name, etc.), the period for which history is to be counted, the content of history display instructions such as the history output format, etc. Shall be included.

At the next step S302, when the transmission / reception unit 62 receives the history display request message, the step S302 is performed.
Proceed to 303. In step S303, the history display execution unit 45 generates history data. That is, the count value C is aggregated for each area based on the contents of the history display instruction from the user, and history data is generated.

When the history data is generated in step S303, the transmitting / receiving unit 62 stores the history data in the user terminal 7
It is transmitted to the transmitting / receiving unit 71 of 0 (step S304). In response to this, the transmission / reception unit 71 receives the history data (step S305), and the history data is stored in the history data storage unit 72.
(Step S306). As a result, the user can display the history data as shown in FIG. 6 on the display unit 15 at an arbitrary timing, and can utilize it as movement history information. Further, when the history data is received as text, it may be displayed on the display unit 15 after being arbitrarily processed such as creating a graph based on the text data.

In step S307, it is determined whether or not there is an area counter clear request. If it is determined that there is no area counter clear request, the process ends.
On the other hand, if it is determined that there is an area counter clear request, the process proceeds to step S308, and in response to this, the history display execution unit 4
5 deletes the count value C of the area counter 44 and the position information history P, and ends the series of processes.

According to the history information acquisition system as described above, the action history can be easily grasped without performing any complicated operation. In addition, by displaying the action history in combination with the map, it is possible to visually recognize areas that are frequently visited, which is convenient. Further, in the history information acquisition system as described above, the portable information terminal 50 and the user terminal 70 do not necessarily have to be the same, and a family member of the user who owns the portable information terminal 50 can operate the user terminal 70 at home. Operate the server 60
The user's action history can also be grasped by accessing. Therefore, especially in a household with children or the elderly, the family can grasp the behavior patterns of the children and the elderly, and thus the history information acquisition system can be used as a help to prevent accidents.

In the above embodiment, the server 60 side counts the count value C and the like to generate history data based on the user's history display instruction. However, such processing is performed on the user terminal 70 side. You may do it. That is, when the server 60 receives the history display request message from the user terminal 70, the position information history P of the period for which the history should be displayed is transmitted to the user terminal 70 based on the instruction from the user. Then, the count value C may be counted and history data may be generated on the user terminal 70 side. Therefore, the area counter 44 and the history display execution unit 45
May be held on the user terminal 70 side. Further, in the above-described embodiment, the flow of processing when the server 60 generates history data and transmits it to the user terminal 70 has been described, but the portable information terminal 5 described above as the user terminal 70.
It is also possible to use 0.

As described above, according to the present invention,
The past position information history can be effectively used, and the action history can be easily and easily grasped.
