(First embodiment)
FIG. 1 is a block diagram showing the configuration of a location information management server 100 according to the first embodiment having the function of the user location information acquisition device of the present invention. In the location information management system according to the present embodiment, a plurality of different types of detectors are detected using a plurality of different types of detectors, and the location information management server 100 uses the signals received from the detectors. The location information is acquired, notification information based on the acquired location information is generated, and notification is made to other applications. In the present embodiment, there are a plurality of detectors for each type of target to be detected, readers 10a to n for detecting active tags 20a to 20n provided to users, and wireless routers 30a to 30a for detecting notebook PCs 40a to n. n, local radio base stations 50a-n for detecting extension PHSs 60a-n, and IC card readers 80a-n for detecting employee IDs 70a-n. In the present embodiment, the thing to be detected is the property held by the user, but is not limited to the property and may be anything associated with the user.

  Further, when the detector detects these possessions, the detector is not limited to detecting the possession itself, and the detector may detect a tag or the like attached to the possession as the possession. . Furthermore, the detection is not limited to detection of an identification signal such as a wireless signal when detecting the property, and any detection means may be used such as detection by contact between the property and the detector.

  That is, in the present embodiment, the active tags 20a to 20n are used as the property of the user. However, the active tag is provided in the property of the user, and the identification information transmitted from the active tag is provided. You may use as information which identifies. Even when the identification information is used as described above, the position information of the user can be detected from the position information of the property by the process described later.

  The detection target and the detector in the present embodiment will be described. First, the active tags 20a to 20n and the readers 10a to 10n for detecting them will be described. It is assumed that the active tags 20a to 20n are provided for each user in the present embodiment. Furthermore, the active tags 20a to 20n transmit identification signals every second by radio waves. This identification signal includes the property ID that identifies the active tag. In the present embodiment, the tag is not limited to a tag that actively transmits radio waves, and may be a passive tag, for example. As a more specific example, communication may be performed using a passive RFID tag or the Bluetooth standard or ZigBee standard that actively emits radio waves.

  When the readers 10a to 10n receive identification signals from things such as the active tags 20a to 20n, the property IDs and the like included in the received identification signals are sent to the address and port indicating the location information management server 100. Send. Then, the position information management server 100 stores the transmitted property ID in association with the detector IDs indicating the readers 10a to 10n.

  For other detection targets and detectors, the same processing as in the case of the readers 10a to 10n and the active tags 20a to 20n is performed. For example, when the local radio base stations 50a to 50n communicate with the extension PHS 60a to n, a unique ID or extension number of the extension PHS 60a to n is used as a call identifier for specifying the extension PHS 60a to n. The local radio base stations 50a to 50n transmit the individual identifiers to the location information management server 100 as property IDs. As a result, the location information management server 100 stores the property IDs indicating the extension PHSs 60a to 60n and the detector IDs that identify the local radio base stations 50a to 50n in association with each other. The notebook PCs 40a to 40n and the wireless routers 30a to 30n perform the same process. In this case, it is conceivable to use a computer name or a MAC address as the property ID. The employee IDs 70a to 70n and the IC card readers 80a to 80n are similarly processed. In this case, the employee code may be used as the property ID.

  FIG. 2 is an explanatory diagram illustrating an example of possessed items carried by a user who is a target for acquiring position information in the position information management server 100 in the present embodiment. As shown in this figure, the user carries a plurality of possessions. These belongings move with the user as necessary, or are placed in a predetermined place without being carried when the user moves. These possessions can be detected by the detector described above. The correspondence between the user and the property is stored in advance in the storage unit 101 described later. Thereby, when the position information of the possession is acquired, the position information of the possession can be regarded as the position information of the user based on the correspondence relationship.

  In this embodiment, the tag ID detected from the active tags 20a-n, the computer name identifying the notebook PCs 40a-n, the unique ID detected from the extension PHS 60a-n, and the employee IDs 70a-n are detected. The employee code to be used is used as the property ID for identifying the property. As a result, the position information management server 100 can collectively manage the possessed property ID and the positional information in association with each other regardless of the type of the owned property.

  The on-site radio base stations 50a to 50n, the wireless routers 30a to 30n and the readers 10a to 10n serving as detectors are connected to the location information management server 100 via a network, and an IP address is assigned to each detector. ing. In addition, the location information management server 100 holds a detector ID that identifies the detector and an IP address that indicates the detector in association with each other. The location information management server 100 stores the correspondence between the IP address of the detector and the detector ID in advance, thereby identifying the detector from the source address included in the header when the information is received. it can. The table structure that holds the correspondence relationship will be described later.

  Further, as a form different from the present embodiment, each detector may hold a detector ID and may be transmitted as identification information including information indicating that a detection target has been detected and the detector ID.

  FIG. 3 is an explanatory diagram conceptually showing the overall configuration of the location information management system including the location information management server 100. The identification signals detected by the readers 10a to 10c as detectors are transmitted to the positional information management server 100 via the network, and the positional information management server 100 acquires the positional information of the user or the object based on the received information. The application A201 to application D204 are notified through the network. Further, the notifications for the application A201 to the application D204 may be transmitted every predetermined time, or may be transmitted when there is a request from each application.

  Returning to FIG. 1, the location information management server 100 includes a storage unit 101, a reception processing unit 102, a device information management unit 103, a location information acquisition unit 104, a location information DB management unit 105, and a user location. It includes an information acquisition unit 106, a notification information generation unit 107, a notification processing unit 108, and a request reception unit 109, acquires user location information from the received signal, generates notification information, and generates other applications. Notify

  The storage unit 101 stores a device database 111 and a position information database 112. In addition, the storage unit 101 can be configured by any commonly used storage unit such as an HDD, an optical disk, a memory card, and the like.

  The device database 111 stores a detector position management table, a communication distance management table, and an possession detection management table. FIG. 4 is a diagram showing the structure of the detector position management table. As shown in the figure, the detector position management table holds detector IDs, detector position information, and detector IP addresses in association with each other. By associating the detector ID with the IP address of the detector, the detector ID can be specified from the address of the transmission source included in the identification information transmitted from the detector. Further, the position information of the detector can be specified from the correspondence between the specified detector ID and the position information.

  FIG. 5 shows the structure of the communication distance management table. As shown in the figure, the communication distance management table holds possession IDs and communication distances in association with each other. Thereby, the communicable distance of the possession can be acquired from the possession ID of the detected possession. When the position information of the property is acquired from the identification information received from the detector, the property is considered to exist within the communication distance range from the acquired position information. That is, as the communicable distance is shorter, the range in which the property exists is limited, and the accuracy of the acquired position information is higher. In this way, it is possible to obtain the accuracy of the position information of the property acquired based on the communicable distance.

  FIG. 6 is a diagram showing the structure of the possession detection management table. As shown in this figure, the property detection management table holds property IDs, detector IDs, and detection times in association with each other. In other words, the property detection management table, when receiving the identification information from the detector, the property ID included in the identification information, the detector ID indicating the specified detector, and the time when the identification information is received. Is added by the device information management unit 103 to be described later.

  The position information database 112 stores a retention probability management table, an owned position management table, and a user position information management table. FIG. 7 is a diagram showing the structure of the retention probability management table. As shown in the figure, the retention probability management table retains user IDs, property IDs, and retention probabilities in association with each other, in other words, corresponds to user thing correspondence information and retention probability correspondence information. Further, the retention probability management table can acquire the probability that the user indicated by the user ID holds the property indicated by the property ID.

  FIG. 8 is a diagram showing the structure of the possession position management table. As shown in the figure, the property position management table holds property IDs, position information, and detection times in association with each other. In other words, each time the position information of the possession is acquired, a record in which the acquired position information, the possession ID, and the detection time are associated is added.

  FIG. 9 is a diagram showing the structure of the user location management table. As shown in this figure, the user location management table holds a user ID, location information, and detection time in association with each other. That is, each time the user position information is specified, a record in which the specified position information, the user ID, and the detection time are associated is added.

  Returning to FIG. 1, the reception processing unit 102 performs a process of receiving the identification information transmitted from the detector. In the present embodiment, the reception processing unit 102 receives identification information received via the network from the detectors indicated by the readers 10a to 10n, the wireless routers 30a to 30n, and the local wireless base stations 50a to 50n. The received identification information includes the property ID that identifies the property detected by the detector. Further, the reception processing unit 102 acquires the IP address of the detector that transmitted the identification information from the header of the identification information. The identification information received by the reception processing unit 102 is information predetermined to be transmitted from the detector, in other words, corresponds to predetermined information. The reception processing unit 102 associates the property ID, the detector ID address, and the detection time and outputs the same to the device information management unit 103 to instruct to update the device detection management table. The detection time is the time when the detector is considered to have detected the property, in other words, the time when the identification information is received from the detector.

  The device information management unit 103 performs processing such as referring to each table held in the device DB or adding, changing, or deleting a record. When the device information management unit 103 receives an instruction to update the device detection management table along with the input of the possession ID or the like, the device information management unit 103 refers to the detector position management table and identifies the detector ID from the IP address of the detector. Information that associates the specified detector ID, property ID, and detection time with each other is updated with respect to a record that matches the detector ID and property ID of the device detection management table. Thereby, the device detection management table can hold a record in which the detector ID, the property ID, and the detection time are associated with each other based on the latest detection information.

  In addition, the device information management unit 103 deletes records that have not been updated for a certain period from the records held in the device detection management table. In the present embodiment, this fixed time is 3 seconds. As described above, since the record before 3 seconds is deleted, only the latest detection information is held. Further, since records within 3 seconds are held, for example, when any active tag is detected by the reader 10a, the reader 10b and the reader 10c, the property ID indicating the active tag and the detector ID indicating these readers Are updated or added. Then, when it is detected only by the reader 10a and the reader 10b after one second, two records associated with the detector ID indicating the reader a10 and the reader 10b and the property ID indicating the detected active tag are updated, The record in which the reader ID indicating the reader 10c and the property ID are associated with each other is not updated, and the information one second before is retained. That is, if it is detected even once within 3 seconds, a record in which the tag ID is associated with the property ID is held. Therefore, even when the signal from the active tag cannot be detected temporarily due to some trouble, the position information can be acquired based on the information detected within 3 seconds.

  The position information acquisition unit 104 records the property ID held in the device detection management table from the device information management unit 103 every 3 seconds, the record information in which the detector ID and the detection time are associated, and the record information The position information associated with the held detector ID and the detector position management table, and the communication distance associated with the property ID held in the record information and the communication distance management table are received. . Thereby, the position information of the property can be acquired every 3 seconds.

  In addition, the position information acquisition unit 104 associates the possessed property ID of the property for which the position information has been acquired with the acquired position information and detection time, and outputs them to the position information DB management unit 105 described later. As a result, the position information DB management unit 105, which will be described later, updates the property position management table, so that the latest property position information can be managed.

  Next, a detailed procedure for the position information acquisition unit 104 to acquire the position information of the property will be described. For example, when there is only one detector that has detected the property, the communication distance associated with the property ID indicating the property detected in the communication distance management table is determined with the position coordinate of the detected detector as the center. The range is the existence range of the property. Further, when there are a plurality of detectors that detect one property, any method among various methods may be used as a method for acquiring position information of the property. For example, for each detected detector as described above, the range determined by the communication distance associated with the possession ID with the position coordinate of the detector as the center is calculated, and the overlapping range of these ranges is calculated as the possession of the possession. It may be defined as the existence range. The range defined by the communication distance managed by the communication distance management table with the average value of the detected position information of the detector as the center may be set as the existence range of the property. Furthermore, the range determined by the above-described procedure centering on the position coordinates obtained by preliminarily holding the signal intensity when the detector detects the property and taking the average value obtained by weighting the detected position information with the signal intensity. May be the range of possession.

  Note that the position information acquisition unit 104 may perform processing by distributing the acquisition of the position information of the detected property for 3 seconds. As a specific example, the position information acquisition unit 104 acquires the number of property IDs detected from the device detection management table within 3 seconds from the device information management unit 103 every 3 seconds. Next, the position information acquisition unit 104 records information associated with the detected property ID, detector ID, and detection time held in the device detection management table from the device information management unit 103 every 3 seconds. The detector ID indicating the detector that has detected the property held by the detector position management table and the position information associated with the detector ID are acquired.

  And the position information acquisition part 104 performs the process for acquiring the position information of one possession for every calculation interval which remove | divided 3 seconds by the number of the possession ID detected. As a result, it is possible to acquire the position information of all possessions detected in 3 seconds and to distribute the processing load.

  The position information DB management unit 105 performs processing on each table held in the position information database 112. In the present embodiment, the position information DB management unit 105, when the property ID, the information associated with the position information and the detection time are input from the position information acquisition unit 104, the input property ID, The possession position management table is updated with position information and detection time as one record. In addition, the location information DB management unit 105 indicates to the user location information acquisition unit 106 the record information held in the possession location management table and the possession detected from the retention probability management table every 3 seconds. The record information holding the object ID is output. Further, when the position information DB management unit 105 receives an instruction for a predetermined process from the user position information acquisition unit 106, the position information DB management unit 105 performs a process based on the instruction for each table and outputs a process result. This specific instruction will be described later. When information associated with a user ID, position information, and detection time is input from the user position information acquisition unit 106, the position information DB management unit 105 uses the input information as one record. Update the person location management table.

  In addition, the position information DB management unit 105 deletes records that have not been updated for a certain period from the records held in the possession position management table and the user position management table. In the present embodiment, this fixed time is 3 seconds. As described above, since the record before 3 seconds is deleted, only the latest position information is held.

  Further, when the position information DB management unit 105 receives a predetermined instruction from the notification information generation unit 107 described later, the position information DB management unit 105 outputs the record information held in the user position management table to the notification information generation unit 107.

  In addition, when the location information DB management unit 105 receives a request to transmit location information of a user together with a transmission destination and a transmission condition from a request reception unit 109, which will be described later, a condition to transmit from the user location management table Is acquired, and the acquired record information is output to the notification information generation unit 107 together with the input destination and a request to generate notification information. Thereby, notification information based on the user's position information can be output in response to a request from another application.

  The user position information acquisition unit 106 holds the record information held in the property position management table from the position information DB management unit 105 and the property ID indicating the property detected from the retention probability management table every 3 seconds. Record information to be input is input, and the position information of the user is acquired based on the record information. Note that record information input from the possession position management table is associated with possession ID, position information, and detection time. The record information input from the retention probability management table is associated with the possession ID, the user ID, and the retention probability.

  Further, when the record information holding the property ID indicating the property detected from the retention probability management table is input, the user position information acquisition unit 106 acquires the property ID from all the input record information. The number of unique user IDs associated with is calculated. Then, the user position information acquisition unit 106 performs a process of acquiring the user position information for each time interval obtained by dividing 3 seconds by the calculated number of user IDs. As a result, it is possible to distribute the load caused by the process of acquiring the user's position information. In addition, the user ID for which the position information is acquired is the record information input in the retention probability management table, and the unique user ID is extracted from the user ID associated with the possession ID. Can be identified. A process of acquiring the position information of the user indicated by each identified user ID at each time interval described above is performed. Next, a process for acquiring position information for each user performed at each calculated time interval will be described.

  The user position information acquisition unit 106 selects the position information selected based on a predetermined criterion from the input position information of the possessed object, and the possessed object ID and the holding probability associated with the selected position information. Acquired as user location information indicated by the user ID associated in the management table. This predetermined standard may be any standard, but in the present embodiment, a standard defined based on the state in which the user possesses the property and the existence range of the property is used. I will do it. Note that this embodiment does not limit a predetermined standard, for example, only one of a standard determined based on the possessed property and a standard determined based on the existence range. It may be used to select position information.

  Further, the user position information acquisition unit 106 uses a holding probability that the user holds the property as a state where the user possesses the property. In other words, the user position information acquisition unit 106 considers that the user exists in the existence range of the possessed items having a high retention probability among the detected possessed items.

  When it is time to calculate the position information, the user position information acquisition unit 106 has the highest holding probability from the possession ID and the holding probability associated with the user ID for which the position information is to be acquired. Select the property ID. Of course, the property ID to be selected is limited to that for which position information is detected. Then, the user position information acquisition unit 106 sets the position information associated with the selected property ID as a candidate for the user position information. Next, a process for specifying position information based on the existence range is performed.

  Then, the user position information acquisition unit 106 determines that the position information determined as a candidate if the position information set as a candidate is the narrowest in comparison with other position information associated with the same user. Is determined as the user's location information. This is because the range of presence is the narrowest, and is considered to be the most accurate as the range of users. An example of the position information selected in this way will be described next.

  FIG. 10 is a diagram illustrating an example of the user existence range specified by the user position information acquisition unit 106 in a state where the employee ID, active tag, and extension PHS possessed by the user are detected. In this figure, it is assumed that the shaded area is specified as the existence range of the user. Further, the user ID of the user whose existence range is specified is “PERSON1”, and the detected owner ID among the owner IDs associated with this user ID is the property ID of the employee card. It is assumed that “2005Z0001”, possession ID “TAGID0001” of the active tag, and possession ID “PHSID0001” of the extension PHS. The association between the possession ID and the user ID is specified from the retention probability management table shown in FIG. Then, the user position information acquisition unit 106 selects the position information of the user indicated by the user ID “PERSON1” from the position information associated with the detected property ID.

  In the retention probability management table, the retention probability associated with these possession IDs “2005Z0001”, “TAGID0001”, and “PHSID0001” is the highest in “95%” of the possession ID “2005Z0001”. For this reason, the user location information acquisition unit 106 treats the location information associated with the possession ID “2005Z0001” as a candidate for the location information of the user. Further, referring to the possession position management table shown in FIG. 8, among the position information associated with the possession IDs “2005Z0001”, “TAGID0001”, and “PHSID0001”, it is associated with the possession ID “2005Z0001”. The existing range of position information is as narrow as '0.2 m'. Thus, in the state shown in FIG. 10, the user position information acquisition unit 106 treats the position information associated with the possession ID “2005Z0001” indicating the employee ID as the position information of the user.

  However, the existence range of the position information associated with the possession ID having the highest retention probability is not necessarily the narrowest. In the example shown in FIG. 10, the possession ID “2005Z0001” indicating the employee ID has the highest retention probability, but the communication distance of the possession ID “2005Z0001” is “0.2 m”. High, but often cannot be detected due to short communication distance. For example, an IC card reader that reads an employee ID card is usually installed at a predetermined position for use when entering or leaving a room, and is not installed at intervals of 0.2 m. In other words, it cannot be detected when the user is 0.2 m or more away from the installed IC card reader.

  That is, it is necessary to provide a criterion for improving the accuracy of the position information of the user when the existence range of the position information associated with the possession ID having the highest retention probability is wide.

  Therefore, the user position information acquisition unit 106 performs the process described later when the position information set as a candidate has a wider existence range than the position information of other possessed items associated with the same user ID. First, the user position information acquisition unit 106 determines that the position information existing range included in the candidate includes the position information existing range included in the position information existing range as the candidate. If it is determined, the included position information is treated as the user position information. Further, when a plurality of position information existence ranges are included in the candidate position information range, any of the plurality of position information existence ranges may be selected. In the present embodiment, position information with the highest retention probability is set as a new candidate, and the same process is performed again to select position information.

  In other words, if the existence range of position information with a low retention probability is included in the existence range of position information with a high retention probability, the user collectively holds the property indicated by these position information. As a result, even if the holding probability is low, position information having a narrow position information existence range can be used as the position information of the user. Thereby, since the position information with a narrow existence range can be selected, the accuracy of the position information of the user can be improved.

  In addition, the user position information acquisition unit 106 determines that the existence range of the position information determined as the candidate does not include the existence range of the position information of other possession narrower than the existence range of the position information determined as the candidate. In this case, the candidate position information is handled as the user position information.

  In other words, if the location information of the candidate location information does not include location information of other possessions with a narrow presence range, it can be determined that the user holds only one of them, so the user location The information acquisition unit 106 treats position information having a high retention probability as user position information.

  FIG. 11 shows the case where the employee ID and the active tag are not detected, the notebook PC and the extension PHS possessed by the user are detected, and the existence range of the extension PHS is included in the existence range of the notebook PC. FIG. 6 is a diagram showing an example of a user existence range specified by the user position information acquisition unit 106. In this figure, it is assumed that the shaded area is specified as the existence range of the user. Further, the user ID of the user whose position information is to be specified is “PERSON1”, the property ID associated with this user ID is the property ID “2005Z0001” of the employee ID, and the property of the active tag ID 'TAGID0001', extension PHS possession ID 'PHSID0001', and notebook PC possession ID 'PCID0001'. Of these, the property ID “2005Z0001” of the employee ID is set as the property ID that has not been detected, the property ID “TAGID0001” of the active tag, the property ID detected is the property ID “PHSID0001” of the extension PHS, and the note It is assumed that the possession ID “PCID0001” of the PC. Then, when acquiring the position information of the user ID “PERSON1”, the position information associated with the detected “PHSID0001” and “PCID0001” is selected.

  In the retention probability management table, the retention probability associated with these possession IDs “PHSID0001” and “PCID0001” is highest in “50%” of the possession ID “PCID0001”. For this reason, the user position information acquisition unit 106 treats the position information associated with the possession ID “PCID0001” as a candidate for the user position information. Next, the user position information acquisition unit 106 considers the existence range based on the position information. Since the existence range of “PCID0001” is 100 m and the existence range of “PHSID0001” is 15 m (however, it is not shown as a record on the possession position management table), the user position information acquisition unit 106 has the extension PHS. It is judged that the existence range of is narrower. In the state shown in FIG. 11, since the existence range of the extension PHS is included in the existence range of the notebook PC, the user position information acquisition unit 106 displays the position information of the extension PHS as the position of the user. Treat as information.

  FIG. 12 shows the case where the employee ID and the active tag are not detected and the notebook PC and the extension PHS that the user possesses are detected, but the extension range of the extension PHS is not included in the range of the notebook PC. FIG. 6 is a diagram showing an example of a user existence range specified by the user position information acquisition unit 106. In this figure, it is assumed that the shaded area is specified as the existence range of the user. The user ID and property ID are the same as those shown in FIG. Similarly to FIG. 11, the position information of the user indicated by the user ID “PERSON1” is selected from the position information associated with the detected “PHSID0001” and “PCID0001”.

  In the retention probability management table, the retention probability associated with these possession IDs “PHSID0001” and “PCID0001” is highest in “50%” of the possession ID “PCID0001”. For this reason, the user position information acquisition unit 106 treats the position information associated with the possession ID “PCID0001” as a candidate for the user position information. In the state shown in FIG. 12, the presence range of the extension PHS is not included in the presence range of the notebook PC, so the user position information acquisition unit 106 has the possession ID ′ of the notebook PC that is a candidate. The position information associated with the PCID 0001 ′ is handled as the user position information.

  Then, the user position information acquisition unit 106 outputs the selected user's position information to the position information DB management unit 105 in association with the user ID and the detection time. Thereby, the position information DB management unit 105 updates the information input to the user position management table as record information. Thereby, the latest location information of the user can be managed.

  Returning to FIG. 1, the notification information generation unit 107 acquires the user location information held in the user location management table by instructing the location information DB management unit 105, and based on the acquired location information. Notification information to be sent to the application. In the present embodiment, the notification information generation unit 107 generates notification information including the detected user position information and information in which the user ID and the detection time are associated with each other at predetermined time intervals. And output to the notification processing unit 108 together with the transmission destination indicating the application application of the transmission destination. The transmission destination is acquired from the storage unit 101. The predetermined time interval is 3 seconds in the present embodiment, but of course, the time interval is not limited.

  In the present embodiment, the notification information generation unit 107 receives an instruction for generating notification information from the position information DB management unit 105 together with information for generating notification information and a transmission destination. When the notification information generation unit 107 receives an instruction to generate notification information from the position information DB management unit 105, the notification information generation unit 107 generates notification information based on the input information for generation, and then from the position information DB management unit 105. The input destination and the generated notification information are output to the notification processing unit 108.

In addition, the present embodiment does not limit the procedure for generating notification information when the procedure for generating notification information is received as described above, and the procedure for generating notification information is not limited. Manage the conditions for generating notification information in the table, acquire the conditions for generating notification information by referring to this table, and generate the notification information by acquiring location information that matches this condition. You may use the procedure to do.

  When the notification information and the transmission destination are input from the notification information generation unit 107, the notification processing unit 108 performs a process of transmitting the notification information to the transmission destination. Any method may be used for transmission.

  As a transmission method, for example, it is conceivable to use 'HTTP-GET' or 'Socket' as a transmission protocol. Further, the transmission method may be changed for each transmission destination. When changing the transmission method, although different from the present embodiment, for example, table information in which the transmission destination and the transmission method are associated in advance may be stored in the storage unit 101.

  In addition, when performing processing to be transmitted from the notification processing unit 108, encryption processing may be performed. By this encryption processing, the location information management server 100 is encrypted between the application and information leakage can be prevented. Any process may be used for the encryption process, such as Ipsec, https, SSL, or DES.

  The request reception unit 109 receives a request for transmitting position information from an application or process connected to the position information management server 100, and performs processing for outputting position information suitable for the request. In addition, the request reception unit 109 receives a request for transmitting information from another application and a transmission condition. If a request is received from another application, the request reception unit 109 determines the application that requested transmission as the transmission destination, and sends a request to transmit the transmission destination, transmission conditions, and position information to the position information DB management unit. To 105.

  Next, the notification information generated based on the position information of the user acquired after receiving the identification information from the detector in the position information management server 100 according to the present embodiment configured as described above is output. The process up to will be described. FIG. 13 is a flowchart showing the above-described processing procedure in the location information management server 100 according to the present embodiment.

  First, the reception processing unit 102 performs a process of receiving identification information input from detectors such as the readers 10a to 10n (step S1301). Then, the property ID included in the received identification information, the IP address of the detector, and the received time are output to the device information management unit 103 as a detection time.

  Next, the device information management unit 103 acquires a detector ID corresponding to the IP address of the detector from the input information, from the detector position management table. The device information management unit 103 updates the record identified with the property ID and the detector ID as a key in the device detection management table with information in which the property ID, the detector ID, and the detection time are associated (step). S1302).

  The device information management unit 103 records the record information managed by the device detection management table, the position information associated with the detector ID held in the record information and the detector position management table, and this The distance information associated with the property ID held in the record information in the communication distance management table is output to the position information acquisition unit 104 every 3 seconds (step S1303).

  Then, the position information acquisition unit 104 holds the record information of the input device detection management table, the position information associated with the detector ID held in the record information, and the record information. The position information of the property indicated by the property ID is acquired from the distance information associated with the property ID (step S1304). Then, the position information acquisition unit 104 outputs the acquired position information to the position information DB management unit 105 in association with the property ID and the detection time.

  Next, the position information DB management unit 105 associates the property ID, the position information, and the detection time input from the position information acquisition unit 104 as record information, and updates the property position management table using the property ID as a key. (Step S1305). Further, the position information DB management unit 105 records information held in the possession position management table every 3 seconds, the possession ID held in the record information, and the user associated with the retention probability management table. The ID and the retention probability are acquired and output to the user position information acquisition unit 106.

  The user position information acquisition unit 106 is associated with the record information held in the property position management table from the position information DB management unit 105 every 3 seconds and the property ID included in the record information. The user ID and the holding probability are received (step S1306).

  Next, the user location information acquisition unit 106 calculates the number of unique user IDs from the user ID associated with the input property ID (step S1307).

  Then, the user position information acquisition unit 106 obtains the position information selected based on a predetermined standard from the position information associated with the property ID for each time interval obtained by dividing 3 seconds by the number of users. It is acquired as user location information indicated by the user ID associated with the ID (step S1308). By repeating this for 3 seconds, position information can be acquired for each user. A detailed processing flow will be described later. The acquired position information is output to the position information DB management unit 105 in association with the user ID and the detection time. Thereby, the position information DB management unit 105 updates the user position management table (not shown).

  Next, the notification information generation unit 107 acquires the user ID, the user position information, and the detection time stored in the user position management table by instructing the position information DB management unit 105 to acquire the user ID. Notification information to be transmitted to the application is generated based on the position information (step S1309). In addition, the notification information generation unit 107 acquires the transmission destination from the storage unit 101 and outputs the transmission destination to the notification processing unit 108 together with the generated notification information.

  After receiving the generated notification information and output destination, the notification processing unit 108 performs a process of notifying the notification information to the application indicated by the output destination (step S1310).

  According to the above-described processing procedure, it is possible to acquire the position information of the user from the position information of the property, and generate and transmit notification information based on the acquired position information. Note that the processing procedure described above is a process from the reception of identification information from the detector in the positional information management server 100 according to the present embodiment to the output of notification information generated based on the acquired positional information of the user. The example of the procedure is shown, and the present invention is not limited to this processing procedure.

  Next, after the position information of the property is input and the number of unique users is calculated by the user position information acquisition unit 106 of the position information management server 100 according to the present embodiment configured as described above, the number of unique users is used. A detailed processing procedure until the position information of the person is acquired will be described. FIG. 14 is a flowchart showing the above-described processing procedure in the location information management server 100 according to the present embodiment. That is, the processing procedure performed in step S1308 shown in FIG. 13 will be specifically described.

  First, as shown in step S1306 in FIG. 13, the user position information acquisition unit 106 has a user ID associated with an owned ID indicating a detected owned property that is held in advance in the holding probability management table. Have been entered. Therefore, the user position information acquisition unit 106 identifies a unique user ID from the input user ID (step S1401).

  Next, the user location information acquisition unit 106 selects a user ID to be processed from the identified unique user ID every time obtained by dividing 3 seconds by the number of unique user IDs. Then, a process for acquiring position information is started (step S1402).

  Then, the user position information acquisition unit 106 selects an possession ID having the highest retention probability among the possession IDs input in association with the user ID to be processed (step S1403). The position information associated with the property ID is a candidate for user position information.

  Next, the user position information acquisition unit 106 compares the existence range of the position information associated with the possession ID having a high retention probability with the existence range of the position information associated with the other possession ID. Then, the position information associated with the possession ID that is the position information of the user is selected (step S1404). Since the processing until the selection of position information by comparison is already described, the description thereof is omitted. Then, the user position information acquisition unit 106 acquires the selected position information as the position information of the user.

  Next, the user position information acquisition unit 106 outputs the acquired user position information in association with the user ID and the detection time to the position information DB management unit 105 (step S1405). Thereby, the position information DB management unit 105 can update the user position management table based on the latest position information of the user.

  Then, the user location information acquisition unit 106 determines whether location information corresponding to all the user IDs specified in step S1401 has been acquired (step S1406). If it is determined that the location information corresponding to all user IDs has not been acquired, the user ID to be treated is selected after the elapse of 3 seconds divided by the number of unique user IDs. Processing for acquiring position information is started (step S1402).

  If the user position information acquisition unit 106 determines that the position information corresponding to all user IDs has been acquired, the user position information acquisition unit 106 ends the processing assuming that the position information of all detected users has been acquired.

  According to the above-described processing procedure, it is possible to acquire the user position information from the detected position information of the possessed object and update the user position management table. The above-described processing procedure shows an example of the processing procedure from the calculation of the number of unique users according to the present embodiment to the acquisition of the user's location information from the location information of the property, The present invention is not limited to this processing procedure.

  In the present embodiment, the detector is not limited to a reader, a wireless router, a private wireless base station, and an IC card reader, but may be any detector that detects a signal transmitted from an object. Furthermore, not only the signal transmitted from the thing but also the detector itself may transmit a signal or the like to detect the thing.

  Since the user ID indicating the user and the property ID indicating the property are stored in association with each other in the retention probability management table of the location information management server 100 according to the present embodiment, the property owned by the user The correspondence relationship between the objects is held, and the position information of the user can be acquired from the position information of the possessed items. In addition, since this correspondence can hold correspondence with a plurality of possessions for one user, even if any possession is not detected, even one associated possession can be obtained. If it is detected, the user's position information can be acquired, so that the user's position is probable and convenience is improved.

  Further, when the property owned by the user is changed, it is only necessary to change the correspondence relationship, and therefore, processing such as change or deletion of the property used for specifying the position of the user is facilitated.

  When the user carries multiple possessions, the location information selected based on the retention probability of possessing the possession and the existence range of the possession is detected from the detected location information of these possessions. Since the user position information is used, the user position information can be acquired with higher accuracy. Furthermore, since position information selected according to a plurality of conditions is used, accurate position information can be acquired. When calculating the position information, since the probability of holding the property is set for each user, the position information for each user can be calculated with high accuracy.
