  FIG. 1 is a block diagram showing a configuration of a location information management system according to an embodiment of the present invention. In the position information management system according to the present embodiment, active tags 161a to 161n provided to an object, readers 151a to 151n that receive identification signals transmitted from the active tags 161a to 161n, and readers 151a to 151n. The location information management server 100 is connected to. As shown in this figure, the readers 151a to 151n detect signals output from the active tags 161a to 161n. The readers 151a to 151n transmit the information included in the detected identification signal and the measured signal strength to the positional information management server 100 connected through the network. Then, the location information management server 100 transmits, for each application, information acquired based on the transmitted information and the measured signal strength.

  In this embodiment, the object includes not only an object but also a person. As a result, the tag is detected in various situations, for example, the user holds the active tag 161l, the active tag 161m is provided on an object such as a PHS held by the user, and the active tag 161n is provided on a package to be loaded. Thus, the processing described later can be performed.

  In other words, the active tags 161a to 161n correspond to portable information storage media and are provided for each object. In the present embodiment, the active tags 161a to 161n transmit identification signals every second by radio waves. In the present embodiment, the portable information storage medium is not limited to tags that actively transmit radio waves, and may be passive, 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.

  The active tags 161a to 161n hold information for identifying at least the tag itself. In the present embodiment, the active tags 161a to 161n hold tag IDs as information for identifying the tags themselves.

  In other words, the readers 151a to 151n correspond to detection devices. When receiving the identification signals from the active tags 161a to 161n, the tags included in the received identification signals at the address and port indicating the location information management server 100 The ID and the measured signal strength are transmitted and associated with the reader IDs of the readers 151a to 151n in the position information management server 100. The reader ID can be specified from the correspondence between the reader ID and the reader address. The address of the source reader can be specified from the source address included in the header of the packet used when sending the information.

  Further, as a form different from the present embodiment, the readers 151a to 151n may transmit the above information in association with the reader IDs indicating the readers 151a to 151n.

  FIG. 2 is an explanatory diagram conceptually showing the overall configuration of the location information management server 100 of the present invention. Each reader 151a-c transmits the detected identification signal together with the signal strength to the position information management server 100 via the network, and the position information management server 100 acquires the position information of the object based on the received information. The application A201 to application D204 are notified through the network. This notification to the application A201 to the application D204 is transmitted when a predetermined condition is satisfied, and is 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 tag information management unit 103, a location information acquisition unit 104, a location information change determination unit 105, and a location information DB. A management unit 106, a notification information generation unit 107, a filter DB management unit 108, a notification processing unit 109, and a request reception unit 110, and the identification signal transmitted from the readers 151 a to 151 n and the measured signal strength After calculating the position information of the object based on the information, the information that satisfies the filter condition registered for each application in the filtering DB is notified to the application.

  The storage unit 101 stores a device database 111, a position information database 112, and a filtering database 113.

  The device database 111 holds a reader position management table and a tag signal management table. FIG. 3 shows the structure of the reader position management table. As shown in the figure, the reader position management table holds a reader ID, reader position information, reader address, and reader coordinate system in association with each other. The address of the reader indicates, for example, an IP address that identifies the reader. By associating the reader ID with the address of the reader, the reader ID can be specified from the address of the reader of the information transmission source. Thereby, the coordinate system and the position information of the reader can be specified based on the reader ID. The coordinate system is a coordinate system used to indicate the position of the reader in position coordinates, and a different coordinate system is defined for each region. In the present embodiment, it is assumed that a different coordinate system is assigned to each floor. For this reason, the “coordinate system” field holds the rank.

  FIG. 4 shows the structure of the tag signal management table. As shown in the figure, the tag signal management table holds a tag ID, a reader ID, a signal intensity, and a detection time in association with each other. That is, the tag signal management table manages information in which detection time is associated with information transmitted from the readers 151a to 151n as a record.

  The location information database 112 holds an ID correspondence management table and a UID location management table. FIG. 5 shows the structure of the ID correspondence management table. As shown in the figure, the ID correspondence management table holds a UID, a device type, and a tag ID in association with each other. It is assumed that a unique ID is assigned to each of the active tags 161a to 161n regardless of the device type or the like. As a result, it can be managed collectively regardless of the type of device. Specifically, the device type is used for recognizing the manufacturer that produced or sold the tag in an environment where a plurality of types of tags are used, the difference between the active, passive, or communication standards described above.

  FIG. 6 is a diagram showing the structure of the UID location management table. As shown in the figure, the UID position management table holds a UID, a coordinate system, position information, and a detection time in association with each other. Each record held by the UID position management table is generated based on the records held by the reader position management table, the tag signal management table, and the ID correspondence management table.

  The filtering database 113 holds an area table, a UID information management table, and a service filter table.

  FIG. 7 shows the structure of the area table. As shown in the figure, the area table holds a coordinate system, position 1, position 2, and a label in association with each other. The arrowhead of each record indicates the area corresponding to the record. Then, each field of the area table will be described. The “position 1” field and the “position 2” field are used to define a region. Specifically, the rectangular area can be specified by using the position coordinates of the “position 1” field and the position coordinates of the “position 2” field as opposing vertices. The “label” field holds a name indicating the specified rectangular area.

  FIG. 8 shows the structure of the UID information management table. As shown in the figure, the UID information management table holds UIDs, names, and types in association with each other. The name indicates the name of the object, and the name unified in each application can be used by holding it in the UID information management table. Also, by holding the name in the UID information management table, it becomes possible for a human to identify the object itself provided with a tag. The type holds the attribute of the object indicated by the UID, such as whether the object specified by the UID is a person or an object, and if the object is a person, the affiliation destination, and if the object is an object, the property. Thus, filtering based on the attribute of the object can be performed by holding the type in association with the UID.

  FIG. 9 shows the structure of the service filter table. As shown in the figure, an event, a filter type, a UID, a label, a coordinate system, a position, a service type, a cipher, a transmission destination, and transmission information are held in association with each other. The “event” field indicates a condition for transmitting an event. For example, in the case of “coordinate change / update”, the position coordinates where the active tags 161a to 161n are detected have changed from the position coordinates previously detected. Indicates sending an event. The “Filter Type”, “UID”, “Label”, “Coordinate System”, and “Position” fields are fields indicating filtering conditions, and only when the conditions described in these fields are satisfied. Will be sent. In other words, these fields correspond to notification condition information in other words. In addition, when there is no description in these fields, it is assumed that no filtering condition is set. The “service type” field holds a transmission protocol for transmission. The “encryption” field holds an encryption method for transmission to the application. The “transmission destination” field indicates the transmission destination of information, and an application for processing information exists at the transmission destination. The “transmission information” field holds the type of information to be transmitted, in other words, corresponds to notification type information. By holding the type of information to be transmitted in the “transmission information” field, only information necessary for each application can be transmitted. In other words, when the filtering condition held by the record is satisfied, the information held in “transmission information” is acquired, and the acquired information is associated with the record in “transmission destination” and stored in “service” It is transmitted using the transmission protocol set in “Type”. The information to be transmitted can be grasped by referring to the associated “transmission information” field. As a result, a condition to be transmitted for each application is set, and information can be transmitted only when this condition is satisfied.

The service filter table can also add, delete, and change records that serve as filters in response to requests from applications.

  The record information held in these service filter tables holds the filter used when generating the notification information, the transmission destination, the type of information to be transmitted, etc. In other words, it corresponds to the notification rule information.

  The reception processing unit 102 performs processing for receiving information transmitted from the readers 151a to 151n. In the present embodiment, the reception processing unit 102 receives the tag ID and the measured signal strength received from the readers 151a to 151n via the network. When receiving, the IP address of the reader can be specified by referring to the header of the received packet. The tag ID, signal strength, and reader IP address are information determined to be transmitted from the readers 151a to 151n, and in other words, correspond to predetermined information. The reception processing unit 102 requests the tag information management unit 103 to update the tag signal management table with information in which detection times are associated with the received information. The detection time is the time when the readers 151a to 151n detect the active tags 161a to n, that is, the current time when the tag ID or the like is received from the readers 151a to 151n.

  The tag information management unit 103 performs processing on each table held in the device DB. In the present embodiment, the tag information management unit 103 refers to the reader position management table, identifies the reader ID from the reader IP address input from the reception processing unit 102, and inputs the specified reader ID. The record in which the tag ID and the reader ID in the tag signal management table match is updated by associating the tag ID, the signal strength, and the detection time. Thereby, the tag signal management table holds the latest information about the tag ID.

  Further, the tag information management unit 103 retains the tag signal management table for a predetermined time when it is not updated with the record retained in the tag signal management table. In the present embodiment, this fixed time is 3 seconds or more. Thus, for example, when a predetermined active tag is detected by reader a, reader b, and reader c one second ago, but only detected by reader a and reader b this time, a reader indicating reader a and reader b is displayed. Only the record associated with the ID is updated, and the record associated with the reader ID indicating the reader c holds the information one second before. In this way, if it is detected even once within 3 seconds, information associated with the tag ID is held. That is, the position information can be calculated even when a signal from the active tag cannot be detected temporarily due to some trouble.

  The position information acquisition unit 104 holds the reader ID and the detection time associated with the tag ID held in the tag signal management table from the tag information management unit 103 for each predetermined period, and the reader position management table. The coordinate system and position information associated with the reader ID being acquired are acquired, the position information associated with the tag ID is calculated based on the acquired information, and the position information of the active tags 161a to 161n is acquired.

  A method by which the position information acquisition unit 104 specifies position information will be described. For example, when there is only one reader that detects the active tag 161b, the coordinate system and position information of the detected reader are used as the coordinate system and position information indicating the position of the active tag 161b. In addition, as a method for calculating the position information of the active tag 161c when there are a plurality of readers that have detected the active tag 161c, any of various currently proposed methods may be used. A method of taking an average value of weighted position information or weighting the detected position information of the reader with a signal intensity is considered. Then, the position information acquisition unit 104 outputs the acquired coordinate system and position information to the position information change determination unit 105 described later in association with the tag IDs and detection times of the active tags 161a to 161n. The acquired position information corresponds to medium position information in other words.

  Further, the position information acquisition unit 104 acquires the latest position information of each of the active tags 161a to 161n for each predetermined period. In the present embodiment, the predetermined period is 3 seconds. As described above, the tag information management unit 103 holds information for 3 seconds or more. Thereby, the position information acquisition unit 104 can calculate the position information based on the updated information even in a radio wave situation in which the reader can receive a signal transmitted from the active tag only once every three times.

  The position information change determination unit 105 corresponds to the position information associated with the tag ID input from the position information acquisition unit 104 and the tag ID when previously detected input from the position information DB management unit 106 described later. The attached position information is compared to determine whether or not the positions of the active tags 161a to 161n have been changed.

  If the position information change determination unit 105 determines that the position has been changed, the position information change management unit 105 requests the position information DB management unit 106 to update the UID position management table with the changed position information. At this time, the tag information and the detection time are output in association with the position information. Thereafter, the position information change determination unit 105 receives the UID, position information, and detection time as update information from the position information DB management unit 106, and associates the event name “coordinate change / confirmation” with the update information to generate notification information. To the notification information generation unit 107. The received UID is a UID indicating an object that has moved while holding the active tag, and in other words, corresponds to holding identification information.

  The position information DB management unit 106 performs processing on each table held in the position information DB. In the present embodiment, the position information DB management unit 106 receives a tag ID based on the ID correspondence management table and the UID information management table when a position ID is output from the position information change determination unit 105 and a tag ID is input. The position information associated with is acquired and output to the position information change determination unit 105.

  In addition, when the tag ID, the position information, and the detection time are input from the position information change determination unit 105 together with the request to update, the position information DB management unit 106 is associated with the tag ID using the ID correspondence management table. After acquiring the UID, the UID information management table is updated by associating the acquired UID with the position information and the detection time. Further, as long as the object is updated when the object moves, the UID information management table holds the current position information of all the objects having the active tag.

  In addition, the position information DB management unit 106 outputs the record information obtained by updating the UID information management table, specifically the UID, the position information, and the detection time, to the position information change determination unit 105 in association with each other. Accordingly, the position information change determination unit 105 can make a request for generating notification information.

  Further, when an event name and a transmission condition are input from the request reception unit 110 (to be described later) together with a request for transmission, the location information DB management unit 106 displays record information that satisfies the transmission condition as the request reception unit 110. Is output to the notification information generation unit 107 together with the event name received.

  The notification information generation unit 107 generates notification information based on information input together with a request for generating notification information. In the present embodiment, the notification information generation unit 107 inputs / outputs the filter DB management unit 108 from the event name and update information or record information input from the position information change determination unit 105 and the position information DB management unit 106. To generate notification information that satisfies the conditions held in the service filter table. A specific processing procedure until the notification information is generated will be described later. Note that the generated notification information includes an event name, and this allows the destination application to specify when the notification information was generated.

  Further, the notification information generation unit 107 acquires record information corresponding to the information input from the UID information management table, and determines whether or not a condition held by the service filter table is satisfied using the acquired record information. Notification information can also be generated when it is satisfied. As a specific example, the notification information generation unit 107 uses a UID as a key and acquires a record with a matching UID in order to acquire record information corresponding to the input information. As a result, the name and type associated with the input information can be acquired. The name and type are attributes of the object indicated by the UID, in other words, the acquired attribute information.

  The condition that the service filter table holds satisfies the position included in the input information in the rectangular area defined by “position 1” and “position 2” of each record of the service filter table, for example. When the information exists, the condition defined by “position 1” and “position 2” is satisfied.

  As another example, when the “UID” of each record in the service filter table matches the UID included in the input information, the condition defined by “UID” is satisfied. As described above, the notification information generation unit 107 generates notification information when the condition held by each record is satisfied.

  As yet another example, the “UID” of the input information is compared with the field “UID” of the UID information management table, and the matched record information is acquired. When the “type” included in the acquired record information matches the “filter type” of each record in the service filter table, the condition defined by the “filter type” is satisfied. As described above, the notification information generation unit 107 generates notification information when the condition held by each record is satisfied. This filter type is a condition for filtering an object attribute, in other words, it corresponds to attribute information.

  Further, when the condition of the record of the service filter table is satisfied, the notification information generation unit 107 refers to the “transmission information” field of the record indicating the filter, acquires the information described in “transmission information”, and acquires the information Information is included in the notification information. As a result, notification information including information suitable for each application can be generated.

  In the present embodiment, the information described in the “transmission information” field corresponds to the input information or the information input in the table held in the filtering database 113 such as the UID information management table. Information that can be acquired from the relationship. Thereby, the notification information generation unit 107 can acquire information necessary for generating the notification information from the information described in the “transmission information”. Note that the notification information generation unit 107 makes a request to the filter DB management unit 108 as necessary when acquiring information from the filtering database 113.

  The notification information generation unit 107 outputs the generated notification information to the notification processing unit 109. Further, when outputting the notification information, the notification information generation unit 107 outputs the transmission destination and service type held in the record indicating the filter. Further, when the filter holds the encryption, the notification information generation unit 107 outputs the encryption together with the notification information.

  The filter DB management unit 108 performs processing on each table held in the filtering database 113. In the present embodiment, the filter DB management unit 108 acquires a list of filters matching the event name input from the notification information generation unit 107 from the service filter table and outputs the list to the notification information generation unit 107. Further, the information associated with the record information and the update information input to the notification information generation unit 107 is acquired from the UID information management table or the area table, and is output to the notification information generation unit 107.

  In addition, when the filter DB management unit 108 receives information indicating that a filter is to be added from the request receiving unit 110 and information indicating a condition to be added, the filter DB management unit 108 adds a record indicating the condition to the service filter table. Further, when a request to change or delete a filter is input from the request receiving unit 110, the service filter table is similarly changed or deleted. In other words, the filter DB management unit 108 corresponds to notification rule management means in other words.

  When notification information, a transmission destination, and a service type are input from the notification information generation unit 107, the notification processing unit 109 calls a program that performs transmission processing using a transmission protocol held by the service type, and transmits the notification information to the transmission destination. Perform the process. In addition, when encryption is input together with notification information or the like, the notification processing unit 109 transmits the notification information after encryption using the input encryption method.

  With this input encryption method, the location information management server 100 and the application are encrypted. Any means may be used as the encryption means, for example, Ipsec, https, SSL, DES, or the like. In this way, the notification processing unit 109 can prevent information leakage by performing the encryption process. Furthermore, privacy can be maintained and security can be improved.

  FIG. 10 is an explanatory diagram showing a specific example of the relationship between the location information management server 100 and each application. As shown in this figure, the active tag 161a provided to the user A was previously detected by the reader 151a. However, when this time is detected by the reader 151b, the position information change determination unit 105 of the position information management server 100 , It is determined that the movement has been made in comparison with the previous position information. Then, the notification information generation unit 107 of the location information management server 100 filters the information (including the location information) input together with the request to generate the notification information from the location information change determination unit 105 into the service filter table. If the above condition is satisfied, the type of information held in the “transmission information” of the filter is acquired and transmitted to the “transmission destination” held by the filter.

  As a specific example, an application for confirming location will be described. As a filter for an application that performs location confirmation, “Coordinate change / update” is registered in the event, “PERSON” is associated with the filter type, and the location of the application is associated with the destination, and is registered in the service filter table. User information in which a change in position information is detected is always transmitted to the application. Thereby, the application can display the location of all users.

  Next, an application that locks the PC 1001 will be described. First, an application that is installed on the PC 1001 used by the user A and locks the PC 1001 so that other users cannot use it when the user A leaves the seat will be described. “Coordinate change / update” as an event in the filter of the application, “PERSON” as the filter type, UID indicating the user A as the UID, the location of the PC 1001 as the position, and the address indicating the application of the PC 1001 as the destination When the port number is registered in the service filter table in association with each other, the application can acquire information on the user A who is seated on or away from the PC 1001. This filter was registered in the location information management server 100 in response to a request from the application when the user A logged in to the PC 1001. When the user A logs out from the PC 1001, this record is deleted by a request from the application. In this way, by registering, changing, or deleting a filter in response to a request from the application, the application can acquire information suitable for the situation.

  Next, an example of filter processing actually performed when the movement of the user A is confirmed will be described using the table shown in FIG. First, when the movement of the active tag 161a included in the user A is detected, since the movement is detected, the event condition to be transmitted is “coordinate change / update”. If the tag ID of the active tag 161a provided by the user A is TAGID0001, UID: ID0001 can be derived from the ID correspondence management table shown in FIG. Furthermore, type: PERSON can be derived from UID: ID0001 from FIG.

  Next, the presence / absence of a record satisfying these conditions is verified. First, since the event is “coordinate change / update”, no. The record of 4 does not satisfy the condition because the event is “voltage change”. And No. Record 5 does not satisfy the condition because the filter type is “OBJ”. Next, no. The record of 2 does not satisfy the condition because the UID is “ID0002”. And NO. Record 3 is labeled “Conference Room” and does not satisfy the condition because User A was at his seat. That is, no. No. 1 records satisfy all conditions, so The UID of user A and the event name “coordinate change / update” are transmitted by HTTP-GET to “192.168.0.10/per.cgi” held by the record 1.

  The request reception unit 110 receives a request from an application or process connected to the location information management server 100, and performs processing for outputting information suitable for the request or generating a filter. In this embodiment, when the request reception unit 110 receives information held as a filter such as a filter condition and a transmission destination from another application, the request reception unit 110 receives the information received together with the filter registration request as the filter DB management unit 108. Output to.

  In addition to the request for filter registration, the request receiving unit 110 also receives a request for changing a filter or deleting a filter. Then, the received request is output to the filter DB management unit 108 together with information specifying the filter received together with the request, and information indicating the condition to be changed in the case of a change. The conditions for specifying the filter may be any conditions as long as the record can be specified, such as the “transmission destination” field and the “event” field in the service filter table.

  FIG. 11 is an explanatory diagram for explaining an example until the location information management server 100 generates a filter according to a request in response to an application request. As shown in this figure, it is assumed that the application sends a request for transmitting information when a predetermined condition is satisfied to the location information management server 100 together with the condition for transmitting and the type of information to be transmitted. In this case, the request reception unit 110 receives a request to be transmitted periodically together with a condition for transmission and a type of information to be transmitted. Then, the request reception unit 110 generates an event name suitable for the request transmitted periodically. Next, the request reception unit 110 outputs an event name, a transmission condition, a transmission destination, and transmission information (that is, the type of information to be transmitted) to the filter DB management unit 108. Note that the destination is the location of the requesting application. Then, the filter DB management unit 108 adds a record in which the transmission condition, the transmission destination, and the transmission information are associated with each other in the service filter table.

  Thereby, when the update information or record information acquired by the notification information generation unit 107 of the location information management server 100 satisfies the condition of the record added to the service filter table, the update information or the record information is transmitted to the transmission destination indicated by the record. Is done.

  Further, when receiving a request for transmitting information immediately from another application and a condition for transmitting the request, the request receiving unit 110 generates an event name corresponding to the request to be transmitted. Then, the request reception unit 110 outputs the application that has requested transmission to the notification information generation unit 107 as a transmission destination, and outputs a condition and event name to be transmitted to the location information DB management unit 106 together with a request for transmission. As a result, the position information DB management unit 106 acquires record information that satisfies the conditions and outputs the record information to the notification information generation unit 107. The notification information generation unit 107 receives the notification information to be transmitted to the input destination. It can be generated based on record information.

  Next, processing from notification of information such as a tag ID to notification of notification information to the application when there is a change in the position information in the position information management server 100 according to the present embodiment configured as described above explain. FIG. 12 is a flowchart illustrating a procedure of the above-described processing in the location information management server 100 according to the present embodiment.

  First, the reception processing unit 102 receives information such as the tag IDs of the active tags 161a to 161n detected by the readers 151a to 151n from the readers 151a to 151n (step S1201).

  Then, the tag information management unit 103 updates the tag signal management table in association with the tag ID received by the reception processing unit 102, the reader ID of the received lead, the signal strength, and the detection time (step S1202).

  Next, the position information acquisition unit 104 detects the tag IDs of the active tags 161a to 161n detected within 3 seconds from the tag information management unit 103 at every predetermined time, the reader ID and signal strength of the detected reader, In addition, the position information for each reader is acquired, the position information associated with the tag ID is calculated based on the acquired information, and the position information of the active tags 161a to 161n is acquired (step S1203).

  Then, the position information change determination unit 105 compares the position information acquired by the position information acquisition unit 104 with the position information held in the position information database 112 input from the position information DB management unit 106 to determine the position information. It is determined whether or not has been changed (step S1204). If it is determined that the position information has not been changed, the process ends without performing any particular processing (step S1204: No).

  Next, when the position information change determination unit 105 determines that the position information has been changed, the position information DB management unit 106 associates the UID acquired using the tag ID as a key with the position information, the coordinate system, and the detection time. The UID location management table is updated with the attached record (step S1205).

  The notification information generation unit 107 is input when the information updated by the position information DB management unit 106 with respect to the UID position management table and a request to generate notification information are input from the position information change determination unit 105. If the received information satisfies the filter condition indicated by each record of the service filter table, the information specified in the “transmission information” field held by the filter is acquired, and the acquired information is associated with the notification information. Is generated (step S1206).

  Next, the notification processing unit 109 performs processing for notifying the generated notification information to the transmission destination specified in the “transmission destination” field held by the filter (step S1207). At the time of notification, transmission is performed using the transmission protocol held by the service type of the filter, and when the encryption of the filter is defined, encryption is performed using the defined encryption.

  According to the processing procedure described above, it is possible to transmit information suitable for each application after detecting the active tags 161a to 161n. The above-described processing procedure shows an example of the processing procedure from receiving the information such as the tag ID according to the present embodiment to generating the notification information when the position information is changed and performing the notification processing. However, the present invention is not limited to this processing procedure.

  In the above-described processing procedure, the case where the position information is changed as a condition for the position information management server 100 to notify the notification information has been described. However, the condition for notification is not limited to the case where the position information is changed. Any condition can be used as long as it can be set as an event in the service filter table. For example, the power supply of the active tags 161a-n may be reduced.

  Next, the tag information management unit 103 is requested to update the tag signal management table from the reception of information from the readers 151a to 151n in the reception processing unit 102 of the location information management server 100 according to the present embodiment configured as described above. The processing up to this will be described. FIG. 13 is a flowchart showing a procedure of the above-described processing in the reception processing unit 102 of the location information management server 100 according to the present embodiment.

  First, the reception processing unit 102 accepts reception of information such as a tag ID from the readers 151a to 151n (step S1301). Then, it is determined whether information is received from the readers 151a to 151n (step S1302). If it is determined that no information has been received (step S1302: NO), reception is accepted again from step S1301.

  If the reception processing unit 102 determines that information has been received from the readers 151a to 151n (step S1302: Yes), it acquires the received tag ID and signal strength, and further acquires the reader ID from the address of the source reader. (Step S1303).

  Next, the reception processing unit 102 uses the current time as the detection time and associates it with the tag ID, signal strength, and reader ID acquired in step S1303 (step S1304).

  Then, the reception processing unit 102 outputs the associated tag ID, signal strength, reader ID, and detection time to the tag information management unit 103, and requests to update the tag signal management table with the information output to the tag information management unit 103. Is performed (step S1305).

  The tag signal management table can be updated from the received information by the processing procedure described above. The above-described processing procedure is an example of the processing procedure from the reception of information from the readers 151a to 151n according to the present embodiment to the request for information to be updated to the tag signal management table from the tag information management unit 103. Yes, the present invention is not limited to this procedure.

  Then, the position information of the active tags 161a to 161n is acquired from the information held in the tag signal management table. Therefore, after the position information acquisition unit 104 of the position information management server 100 according to the present embodiment configured as described above acquires information such as a tag ID detected within 3 seconds, the position information of the active tag is obtained. Processing until acquisition is described. FIG. 14 is a flowchart illustrating a procedure of the above-described process in the position information acquisition unit 104 of the position information management server 100 according to the present embodiment.

  First, the position information acquisition unit 104 acquires all record information from the tag information management unit 103 until the detection time held in the tag signal management table is 3 seconds before the current time (step S1401). This record information is record information in which the tag ID, signal strength, reader ID, and detection time are associated with each other.

  Then, the position information acquisition unit 104 sets one tag ID that is a target of position information acquisition from the acquired record information (step S1402).

  Then, the position information acquisition unit 104 requests the tag information management unit 103 to determine whether or not the position information of the reader ID associated with the set tag ID and record information exists, and then inputs from the tag information management unit 103. It is confirmed whether or not there is position information associated with the reader ID based on the obtained information (step S1403). At this time, the tag information management unit 103 searches the reader position management table for position information associated with the reader ID.

  Next, when the position information acquisition unit 104 confirms that the position information associated with the reader ID does not exist (step S1403: No), the position information where the tag ID associated with the reader ID exists is It is unknown (step S1404).

  If position information associated with the reader ID exists (step S1403: Yes), the position information acquisition unit 104 determines whether there are a plurality of readers associated with the tag ID (step S1405). . As a specific example, when there are a plurality of record information associated with the tag ID in the tag signal management table, it is determined that there are a plurality of readers associated with the tag ID.

  Next, when the position information acquisition unit 104 determines that there are a plurality of readers (step S1405: Yes), the position information of the active tags is calculated by weighting the position information of the plurality of readers with the signal strength ( Step S1406).

  If the position information acquisition unit 104 determines that there is only one reader that has detected this tag ID (step S1405: No), the position of the reader that has detected this tag ID is used as the position information of the active tag ( Step S1407).

  Then, the position information acquisition unit 104 determines whether or not the position information of all the detected tag IDs has been acquired (step S1408). When it is determined that the position information of all the tag IDs has been acquired (step S1408: Yes), the position information acquisition unit 104 outputs the acquired position information to the position information change determination unit 105 and ends the process.

  When it is determined that the position information of all tag IDs has not been acquired (step S1408: No), the position information acquisition unit 104 sets the next tag ID to be acquired from the tag IDs for which position information has not been acquired. (Step S1409). Then, the process is restarted from step S1403.

  The position information associated with the tag ID can be acquired by the processing procedure described above. The above-described processing procedure shows an example of the processing procedure from acquisition of information such as a tag ID detected within 3 seconds according to the present embodiment to specification as position information. Is not limited to this procedure.

  Next, the notification information generation unit 107 of the positional information management server 100 according to the present embodiment configured as described above monitors a request for generating notification information from another configuration, and when there is a request, the notification information Will be described until notification processing is performed on the notification information generated by the notification processing unit. FIG. 15 is a flowchart illustrating the above-described processing procedure in the notification information generation unit 107 and the notification processing unit 109 of the location information management server 100 according to the present embodiment. In this flowchart, a case where there is one update information or record information input from the notification information generation unit 107 and the notification processing unit 109 will be described.

  First, the notification information generation unit 107 monitors notification information generation requests from the position information change determination unit 105 and the position information DB management unit 106 (step S1501).

  Next, the notification information generation unit 107 determines whether or not a request for generating notification information has been input (step S1502). When it is determined that a notification information generation request has not been input (step S1502: NO), the process is resumed from the monitoring of the notification information generation request in step S1501.

  If the notification information generation unit 107 determines that a notification information generation request has been input (step S1502: Yes), the information associated with the record information or update information input together with the notification information generation request. Is acquired (step S1503).

  As a detailed example of acquiring the associated information, the name and type associated with the UID held in the UID information management table from the UID of the record information or update information input to the notification information generation unit 107 From the input coordinate system and position information, a label associated with the coordinate system, position 1 and position 2 in the area table is acquired.

  Next, the notification information generation unit 107 acquires a list of filters that match the request (step S1504). As a specific example, the UID, coordinate system, and position information that are record information or update information, the event name input, and the name, type, and label acquired in step S1503 are used as filter acquisition conditions. A list of filters satisfying these conditions, in other words, record information of the service filter table is acquired. Note that the record information or the update information and the information acquired in step S1503 are objects to be compared with the conditions set in the filter.

  For example, when a notification information generation request is input together with update information and an event name “coordinate change / update” in step S1502, the notification information generation unit 107 sends record information or update information to the filter DB management unit 108. Information such as the event name and the type acquired in step S1503 is output. The notification information generation unit 107 receives record information of the service filter table that satisfies the output information from the filter DB management unit 108.

  In this way, acquiring a filter that satisfies the condition based on the input update information or record information means that the update information or record information that satisfies the acquired filter condition is selected.

  Then, the notification information generation unit 107 determines whether or not the processing has been completed for all the filters in the list, in other words, all the acquired record information (step S1505). If it is determined that the process has been completed (step S1505: Yes), the process is resumed from the monitoring of the notification information generation request in step S1501.

  If it is determined that the process has not ended (step S1505: No), the notification information generation unit 107 acquires the type of information to be notified from “transmission information” of the acquired record information indicating the filter (step S1506). ). For example, in the case of the record No. 3 shown in FIG. 9, “UID, position, time” is acquired as the type of information to be transmitted.

  Next, the notification information generation unit 107 acquires information to be transmitted based on the type of information to be transmitted acquired in step S1506 (step S1507). In the case of “UID, position, time” as the type of information to be transmitted, the UID, position information, and detection time input in step S1502 are acquired. When information not included in the information acquired in steps S1502 and S1503 is defined as information to be transmitted, the notification information generation unit 107 requests the filter DB management unit 108 to acquire necessary information. . The notification information generation unit 107 outputs the acquired information as notification information to the notification processing unit 109 together with “transmission destination”, “service type”, and the like held by the filter.

  Then, the notification processing unit 109 calls a program for transmitting with the transmission protocol specified by the input “service type” (step S1508).

  Next, when “encryption” is input, the notification processing unit 109 encrypts the notification information using a method designated by “encryption” (step S1509). If “encryption” is not entered, no particular processing is performed.

  Then, the notification processing unit 109 transmits the notification information to the address designated by “transmission destination” (step S1510). Then, the process returns to step S1505, and it is determined whether or not the processing has been completed for all the filters in the list.

  With the processing procedure described above, it is possible to transmit information suitable for each application. In the above-described flowchart, one record information or update information is input from the notification information generation unit 107 and the notification processing unit 109. However, when a plurality of pieces of position information are received, the process from step S1503 to step S1510 is performed. It becomes possible by performing processing for each record information or update information to which a processing procedure is input.

  The above-described processing procedure shows an example of a processing procedure from generation of notification information to notification processing when there is a request by monitoring a request for generation of notification information from another configuration according to the present embodiment. However, the present invention is not limited to this processing procedure.
