Description

  The present invention relates to an object position corresponding control device and an object position corresponding control program for performing control corresponding to the position of an object.

  Traditionally, it has been important to understand customer purchasing behavior in stores to optimize product layout and display methods in retail stores, as well as product lineups, etc. according to customer needs and improve product sales. Sex is recognized. In particular, since it is considered that increasing the contact time between the customer and the product is one of the factors that increase sales, it is necessary to grasp the contact time between the customer and each product. By objectively determining how much improvement measures such as changing display methods, adding display aids, and adding POP advertisements contribute to increasing sales by grasping the contact time between customers and each product It becomes possible.

  For this reason, conventionally, an observation method in which an investigator directly observes customer behavior, a method of recording the customer collection status of each sales floor with a video camera installed in each sales floor in the store, or a predetermined sensor on the sales floor The customer's purchasing behavior was grasped by the method of measuring the number of people passing through the doorway.

  Further, a customer information collection system using a wireless tag has been proposed as a means for grasping customer behavior without using the sampling survey method as described above. In this customer information collection system, the customer identification information stored in the wireless tag held by the customer is read by the reading means installed at the entrance / exit of the store and each sales floor, so that the customer in the store It is possible to obtain the travel route and the staying time at the sales floor where the customer visited. Furthermore, based on the information about the sales floor where the customer visited and the staying time at the sales floor, it is possible to estimate a product that each customer is interested in (see, for example, Patent Document 1).

  Further, as a method for specifying the position of a position specifying object in a predetermined area, a radio signal output from a predetermined fixed base station is received by the position specifying object, and the signal strength of the received signal is A method of estimating the position of the position specifying object based on (RSSI: Received Signal Strength Indication) is also used. In recent years, wireless signals conforming to IEEE 802.11b are generally used in public wireless LANs (Local Area Networks), businesses, and homes. Proposed. Specifically, the position of the position identification target is estimated probabilistically by associating the RSSI transmitted from the position identification target for a plurality of base stations with the RSSI sample data measured in advance at a predetermined point. Has been proposed (see, for example, Patent Document 2).

JP 2006-185293 A Japanese Patent No. 3899356 JP 2004-336194 A JP 2004-340661 A JP 2003-20984 A JP 2003-052077 A

  However, the method of conducting a sampling survey using an investigator, a video camera, or a predetermined sensor is not a method that can grasp the behavior of all customers, and thus the reliability of information obtained is limited. In addition, it is difficult to obtain detailed information for more effective improvement measures because it will greatly increase the labor and cost of surveying to understand trends on different days and times. It was.

  Further, the conventional customer information collection system described above estimates that the customer holding the wireless tag is in the vicinity of the reading means when the reading means reads the customer identification information of the wireless tag. . Therefore, in order to grasp the position of the customer in the store with high accuracy, it is necessary to arrange a large number of reading means over the entire area in the store, resulting in an increase in installation cost.

  In addition, in the position specifying system using a radio signal used in the wireless LAN, an error of about 1 to 5 m may occur with respect to the estimated position of the object. For this reason, the accuracy was insufficient to identify the flow line of the customer in the store, such as in which of the different adjacent passages the customer is located.

  As described above, it is practically difficult to specify the position of the customer with the conventional technique, and no specific service is presented for various services based on the assumption that the position can be specified. For example, in large shopping malls, the number of customers visiting the store is much larger than that of community-based private stores, etc., so there is a demand for understanding the trends of individual customers and serving customers. It was difficult to satisfy such a demand.

  Alternatively, there is a desire to prevent various harmful effects caused by mobile phones held by individual customers, and technologies such as forcibly switching mobile phone modes have been proposed. Since the position could not be specified, it was practically difficult to control the mobile phone in detail according to the position of the customer.

  For example, the technique of Patent Document 3 cannot be controlled unless the user's action schedule is known in advance, and cannot be applied to the control of a user's mobile phone that moves freely within a specific range. In addition, the techniques of Patent Literature 4 and Patent Literature 5 specify the position of the user using GPS, and therefore cannot be applied indoors where satellite radio waves cannot be received. Furthermore, the technique of Patent Document 6 is not practical because a device for generating a special signal for controlling the manner mode and a special receiving mechanism for receiving this signal are required on the mobile phone side.

  The present invention has been made in view of the above, and can identify the position of a customer with low cost and high accuracy, and can take an appropriate action according to the position of the identified object. An object is to provide an object position correspondence control device and an object position correspondence control program.

According to the first and seventh aspects of the present invention, based on the first identification information transmitted from the estimated information transmitting means and the signal strength of the estimated information received by the object, the object is schematically illustrated. Can be estimated. In addition, when the object is located within the specific range, the estimated position of the object is corrected based on the second identification information about the specific information transmitting means corresponding to the specific range, and a more accurate position is obtained. Can be identified. Therefore, by disposing the specific information transmitting means only in the area where the position needs to be specified in detail, the position of the object located within the specific range corresponding to the specific information transmitting means can be accurately specified. . In addition, for the region that only needs to be able to roughly grasp the position, the position of the object can be estimated without arranging the specific information transmitting means, so it is compared with the case where the position of the object is specified in detail uniformly. Thus, the necessary cost can be reduced. In particular, since the control based on the control content related information corresponding to the position of the target object specified with high accuracy is performed, an appropriate response can be performed according to the position of the target object.
In addition, based on the position of the identified object and the purchase area identification information for identifying the purchase area where the customer who owns the object indicates the purchase intention, among the objects located in the specific purchase area Since the position of the object held by the customer indicating the purchase intention in the specific purchase area is output to the predetermined output means in association with the layout information, the purchase area in the own store It is possible to grasp the current position of a customer who has a purchase intention. For this reason, it is possible to grasp the purchase psychology stage of customers who have a purchase intention in the purchase area of their own store, and appropriate sales response according to the current position to the customer showing the purchase intention Can be taken.

According to the present invention as set forth in claim 2, by outputting information indicating the movement route of the object to the output means, the preference and purchase of the customer who has a purchase intention in the purchase area of the own store. By confirming the route, it is possible to take an appropriate sales response according to the travel route to the customer indicating the purchase intention.

Further, according to the present invention as set forth in claim 3, the position of the object held by the customer indicating the purchase intention in the specific purchase area is in a competitive relationship with the specific purchase area. When it is located within a predetermined distance with respect to the purchase area, the fact that the position of the object and the position of the object are located within the predetermined distance is output to the output means. If a customer who has a willingness to purchase at another store (competitor store), such as a customer who owns a leaflet or discount voucher, is in the purchase area of the store, Appropriate measures can be taken such as recommending products from the store itself.

Further, according to the present invention described in claims 4 and 8 , based on the first identification information transmitted from the estimated information transmitting means and the signal strength of the estimated information received by the object, An approximate position can be estimated. In addition, when the object is located within the specific range, the estimated position of the object is corrected based on the second identification information about the specific information transmitting means corresponding to the specific range, and a more accurate position is obtained. Can be identified. Therefore, by disposing the specific information transmitting means only in the area where the position needs to be specified in detail, the position of the object located within the specific range corresponding to the specific information transmitting means can be accurately specified. . In addition, for the region that only needs to be able to roughly grasp the position, the position of the object can be estimated without arranging the specific information transmitting means, so it is compared with the case where the position of the object is specified in detail uniformly. Thus, the necessary cost can be reduced. In particular, since the control based on the control content related information corresponding to the position of the target object specified with high accuracy is performed, an appropriate response can be performed according to the position of the target object.
Further, the control for specifying the control corresponding to the position of the specified object to be performed on the object at each position of the target area, and executing the specified control on the object Since the signal is transmitted to the target object, it is possible to perform appropriate correspondence and control on the target object according to the position of the target object.

According to the fifth aspect of the present invention, the target object performs wireless communication with the target object position corresponding control device via the access point and receives a wireless signal from the tag writer. Since this is a telephone, it is possible to appropriately handle and control the mobile phone according to its position.

According to the present invention as set forth in claim 6, the first mode to be set for the object in the estimation range is specified, and the control for setting the specified first mode for the object is performed. When a signal is transmitted to the object and the position of the object is specified, the signal is set for the object in each specific range corresponding to the position of the specified object. The target second mode is specified, and a control signal for setting the specified second mode with respect to the target is transmitted to the target. The object itself can be switched to an appropriate mode according to the position.

  According to the seventh aspect of the present invention, the control for specifying the first mode to be set for the object in the estimation range and setting the specified first mode for the object is performed. When a signal is transmitted to the object and the position of the object is specified, the signal is set for the object in each specific range corresponding to the position of the specified object. The target second mode is specified, and a control signal for setting the specified second mode with respect to the target is transmitted to the target. The object itself can be switched to an appropriate mode according to the position.

  Embodiments of a position correspondence control apparatus and a position correspondence control program according to the present invention will be described below in detail with reference to the accompanying drawings.

The position correspondence control device and the position correspondence control program according to each embodiment identify the position of the target object in the target region, and execute the control content corresponding to the specified position, according to the position of the target object. The purpose is to take an appropriate response.

  The application target of the position corresponding control device and the position corresponding control program according to each embodiment is arbitrary, for example, a shopping mall, a retail store in a shopping mall, a customer position in a retail store such as a supermarket, an employee in an office building It can be applied to specify the position of a worker, the position of a predetermined product in a factory, and the like. In the first embodiment, a case where the present invention is applied to a shopping mall and a case where a second embodiment is applied to a cinema complex (composite movie theater) will be described.

  In each embodiment, it is roughly estimated that the target object is located within an estimation range that is a certain range within the target region, and the target object is positioned within a specific range that is narrower than the estimation range. The position of the target is specified based on the estimated position and the specific range on the condition that the target is included in the specific range, and based on the specified position The point is to execute predetermined control contents. As a result, it is possible to estimate the approximate position of the object, and it is possible to selectively specify the position of the object when it is necessary to specify a detailed position. Therefore, compared with the case where the position of a target object is specified in detail uniformly, a required cost can be reduced. Moreover, since the specific range in which the position of the object can be specified is narrower than the estimation range in which the position of the object can be estimated, the position of the object can be specified with high accuracy.

  In particular, one of the features of the position correspondence control apparatus and the position correspondence control program according to each embodiment is that control is performed based on control content related information corresponding to the position of the specified object. Thereby, for example, the store clerk of each store in the shopping mall can grasp the purchase psychological stage of the customer who has the purchase intention in the purchase area of the own store, and to the customer showing the purchase intention Appropriate sales depending on the current position. Alternatively, in the cinema complex, according to the location of the customer, the mobile phone held by the customer can be controlled to switch the call mode.

For example, tag IDs corresponding to customers who have decided to purchase at a plurality of stores are stored in association with all of the plurality of stores. In the example of FIG. 8, the customer corresponding to the tag ID = 002 has decided to purchase at stores with different items (Seidoudo and Brand X), and the customers corresponding to the tag ID = 005 and 006 are , Purchasing at a store (brand X and brand Y) where some of the items are common to each other is determined. Alternatively, the tag ID corresponding to the customer who has not determined the store may be stored in association with information indicating that the store has not been determined. In the example of FIG. 8, “store non-specific flag 1” is stored in association with tag IDs = 012, 013, and 014 corresponding to customers who have not determined a store. By setting such information, it is possible to provide a wide range of purchase possibilities for customers that can be identified from the store side.

(Storage unit-data structure-travel route data)
FIG. 9 is an explanatory diagram of an example of the movement route data 131h. The travel route data 131h stores information for specifying the travel route (stop-by route) of each customer. Specifically, the travel route data 131h includes “tag ID”, “stop-by store”, and “stay time” as items as shown in FIG.

  The data corresponding to the item “tag ID” stores the tag ID of the wireless tag 12 distributed to each customer whose travel route is recorded.

  The data corresponding to the item “stop-in store” is information for specifying the store where the customer stopped, and stores all or part of the data common to the data corresponding to the item “store” in the purchase area specifying table 131e. Is done.

  The data corresponding to the item “stay time” is information for specifying the stay time at each store where the customer visited.

(Storage-Data structure-Competition data)
FIG. 10 is an explanatory diagram of an example of the competitive relationship data 131i. In the competitive relationship data 131i, information for specifying mutual competitive relationships in a plurality of stores of the shopping mall 2 is stored. Specifically, the competitive relationship data 131i includes a plurality of records as shown in FIG. 10, and each record has a name of each store as information for specifying a mutually competitive store. Stored. Instead of this name, the ID number of each store may be stored. For example, the first record in FIG. 10 indicates that the store “XX Coffee” and the store “YY 珈 琲” are in a competitive relationship with each other.

(Processing of position control device-overall flow)
Next, the processing operation of the position corresponding control device 13 will be described. First, an overall flow of processing executed by the position correspondence control device 13 will be described with reference to FIG. FIG. 11 is a flowchart showing an overall flow of processing executed by the position correspondence control device 13. As a premise when the position correspondence control device 13 executes the process, it is necessary for the customer visiting the shopping mall 2 to be distributed with the wireless tag 12 associated with the product for which the customer is willing to purchase. For example, when a customer visits a shopping mall 2, at the entrance of the shopping mall 2, an attendant verifies the presence or absence of a store or product that is orally making a purchase intention with the customer. If there is, the wireless tag 12 corresponding to the store or the product (in FIG. 8, the wireless tag 12 in which the tag ID is associated with the item corresponding to the store or the product) is distributed to the customer. For customers who do not have any stores or products that are determined to purchase, the wireless tag 12 in which the tag ID is associated with the store non-specific flag 1 or the item non-specific flag 1 in FIG. 8 is distributed to the customer. To do. Alternatively, after distributing the wireless tag 12, the clerk associates the tag ID of the wireless tag 12 with information related to the store or item that is determined to purchase and inputs it to the store tag ID correspondence table 131g. May be.

  The distribution form of the wireless tag 12 is arbitrary. For example, the wireless tag 12 may be distributed alone, or may be distributed to customers in a state of being attached to a shopping cart. Alternatively, an automatic distribution device for the wireless tag 12 is installed near the entrance of the shopping mall 2, and the wireless tag corresponding to the product is input to the automatic distribution device by the customer himself / herself by specifying information specifying the product to be purchased. 12 may be automatically distributed from the automatic distribution apparatus to the customer. In order to improve the carrying rate of the wireless tag 12 by the customer, when the customer purchases the product, the wireless tag 12 is presented at the purchase store, thereby taking measures such as discounting the price of the product or providing a crude product. You may give it. Note that the wireless tag 12 distributed in this way is collected at the purchase store when the customer purchases the product, or is collected at the exit of the shopping mall 2.

  Estimated information is transmitted from the access point 10 throughout the store in the shopping mall 2, and the estimated information is received by the wireless tag 12 distributed to the customer. When the wireless tag 12 receives the estimated information from the access point 10, the wireless tag 12 stores the content of the received estimated information in the storage unit 123. In addition, the signal strength measuring unit 121 measures the signal strength of the received estimated information, and stores the signal strength information for specifying the measured signal strength in the storage unit 123.

  Further, when the customer approaches the store where the tag writer 11 is installed and the customer enters the specific range corresponding to the tag writer 11, the wireless tag 12 receives the specific information from the tag writer 11, and the received specific information The contents are stored in the storage unit 123. These pieces of information stored in the storage unit 123 include predetermined timing (for example, timing when the movement of the wireless tag 12 is detected by a motion sensor mounted on the wireless tag 12, timing measured by a timer, and the like). , The transmission unit 122 of the wireless tag 12 transmits the signal, and the position correspondence control device 13 receives and processes it via the access point 10.

  When the tag ID, the estimation information, the specific information, and the signal strength information are input from the reception unit 101 of the access point 10, the communication processing unit 130 c of the position correspondence control device 13 receives the input information. Is stored in the signal strength DB 131a together with a time stamp indicating the time when these pieces of information are received (step SA-1).

  Next, the estimation processing unit 130a refers to the signal strength DB 131a and the measured signal strength DB 131b, and executes an estimation process for estimating the position of the wireless tag 12 based on information stored in the signal strength DB 131a and the like (step SA). -2). Subsequently, the identification processing unit 130b executes identification processing for identifying the position of the wireless tag 12 based on the position of the wireless tag 12 estimated by the estimation processing unit 130a and the identification information stored in the signal strength DB 131a. (Step SA-3). When the position of the wireless tag 12 is specified, the position correspondence control unit 130d executes position correspondence control processing based on the specified position of the wireless tag 12, and displays an icon indicating the position of the wireless tag 12 in the shopping mall 2 The image superimposed on the layout image is transmitted to the store terminal 14 (step SA-4). The store terminal 14 receives this image and displays it on a display screen or the like, thereby making it possible to grasp the behavior of the customer who owns the wireless tag 12 corresponding to the product of the store.

(Processing operation of position corresponding control device-estimation processing)
Next, the flow of the above estimation process will be described with reference to FIG. FIG. 12 is a flowchart showing a flow of estimation processing executed by the position correspondence control device 13. The estimation processing unit 130a acquires the tag ID, signal strength information, access point ID, and time stamp stored in association with each other from the signal strength DB 131a (step SB-1).

  Subsequently, each radio identified by the tag ID based on the acquired signal strength information and access point ID, and measurement position information, access point ID, and signal strength actual measurement information stored in the signal strength actual measurement DB 131b. The position for each time stamp of the tag 12 is estimated (step SB-2). Here, a known method can be used as a method of estimating the position of the wireless tag 12. For example, the signal strength information acquired from the signal strength DB 131a may be compared with the measured position information and the measured signal strength information stored in the signal strength measured DB 131b, and the position of the wireless tag 12 may be estimated probabilistically.

  Subsequently, the estimation processing unit 130a outputs estimated position information for specifying the estimated position to the identification processing unit 130b together with a tag ID and a time stamp corresponding to the estimated position (Step SB-3).

(Processing operation of position control device-specific processing)
Next, the flow of the above specific process will be described with reference to FIG. FIG. 13 is a flowchart showing the flow of the specific process executed by the position correspondence control device 13. When the estimated position information of the wireless tag 12, the tag ID corresponding to the estimated position, and the time stamp are input from the estimation processing unit 130a in step SB-3, the specific processing unit 130b receives these information. Are associated with each other and stored in the position specifying result table 131d (step SC-1).

  Next, the specific processing unit 130b refers to the signal strength DB 131a and determines whether or not a tag writer ID is stored in association with the tag ID and time stamp input in step SB-3 (step SC-2). ). When the tag writer ID is not stored (step SC-2, No), the position of the wireless tag 12 cannot be specified in more detail, so the contents of the position specification result table 131d are maintained.

  For example, in the signal strength DB 131a shown in FIG. 3, the data (tag ID “001”, time stamp “2007-10-20 10:21:05”) stored in the first line from the top has a tag writer ID. Not stored. Therefore, as shown in FIG. 6, only the coordinates (8, 0) indicating the position of the wireless tag 12 estimated by the estimation processing unit 130a based on the data are associated with the tag ID and the time stamp, and the position specifying result. It is stored in the table 131d.

  On the other hand, returning to FIG. 13, when the tag writer ID is stored (step SC-2, Yes), the specific processing unit 130b stores the correction type information, the arrangement position information, and the information stored in association with the tag writer ID. Correction range information is acquired from the tag writer arrangement table 131c (step SC-3). Then, the estimated position specified by the estimated position information of the wireless tag 12 input from the estimation processing unit 130a in step SB-3 is included in the correction range specified by the correction range information acquired in step SC-3. It is determined whether or not (step SC-4).

  When the estimated position of the wireless tag 12 is not included in the correction range (step SC-4, No), the identification processing unit 130b determines that the estimated position of the wireless tag 12 should be given priority as the position of the wireless tag 12. In the above-described step SC-1, the state of the position specifying result table 131d in which the estimated position information is stored is maintained.

  For example, in the signal strength DB 131a shown in FIG. 3, the data (tag ID “001”, time stamp “2007-10-20 10:21:20”) stored in the third row from the top is used as the tag writer ID. “10” is stored. According to the tag writer arrangement table 131c shown in FIG. 5, the correction range corresponding to the tag writer ID “10” is (7, 1) to (9, 3). On the other hand, as shown in FIG. 6, since the position of the wireless tag 12 estimated by the estimation processing unit 130a based on the data is (8, 4), there is no correction range corresponding to the tag writer ID “10”. Not included. Accordingly, only the position (8, 4) estimated by the estimation processing unit 130a is stored in the position specifying result table 131d.

  On the other hand, when the estimated position of the wireless tag 12 is included in the correction range (step SC-4, Yes), the specifying processing unit 130b sets the correction type specified by the correction type information acquired in step SC-3. Corresponding coordinates are selected from the arrangement position information acquired in step SC-3, and the selected position is substituted for the coordinates in the estimated position information of the wireless tag 12 to calculate the specific position information (step SC-5). Subsequently, the calculated specific position information is stored in the position specification result table 131d as corrected coordinates (step SC-6). As described above, when the wireless tag 12 is located within a specific range of the arbitrary tag writer 11 and the estimated position of the wireless tag 12 is included in the correction range, the wireless tag 12 is wirelessly transmitted using the arrangement position information of the tag writer 11. The estimated position of the tag 12 is corrected. Therefore, when the wireless tag 12 is located in the vicinity of the tag writer 11, the position of the wireless tag 12 can be specified more accurately.

  For example, in the signal strength DB 131a shown in FIG. 3, the data (tag ID “001”, time stamp “2007-10-20 10:21:22”) stored in the fourth line from the top is used as the tag writer ID. “11” is stored. According to the tag writer arrangement table 131c shown in FIG. 5, the correction type corresponding to the tag writer ID “11” is “Y coordinate”, the installation coordinate is “(8, 5)”, and the correction range is (7, 4) to (9 6). On the other hand, as shown in FIG. 6, since the position of the wireless tag 12 estimated by the estimation processing unit 130a based on the data is (7, 6), it is included in the correction range corresponding to the tag writer ID “10”. It is. Therefore, based on the correction type “Y coordinate”, coordinates (7, 5) obtained by substituting “5”, which is the Y coordinate in the installation coordinates (8, 5), into the Y coordinate of the estimated position (7, 6) of the wireless tag 12. Are stored as data corresponding to the corrected coordinates of the position specifying result table 131d shown in FIG.

(Processing operation of position correspondence control device-position correspondence control processing)
Next, the flow of position correspondence control processing will be described with reference to FIGS. 14 and 15. 14 and 15 are flowcharts showing the flow of position correspondence control processing executed by the position correspondence control device 13. Below, every time a display request is received from the store terminal 14, the position correspondence control process will be described. However, regardless of whether or not a display request is received, the position correspondence control process is always automatically repeated. Real-time processing may be performed.

  First, when the communication processing unit 130c receives a display request from the store terminal 14 (step SE-1), the position correspondence control unit 130d acquires the entire layout image of the shopping mall 2 from the layout DB 131f (step SE-2). . Then, the position correspondence control unit 130d acquires all tag IDs registered in the store tag ID correspondence table 131g (step SE-3), and specifies the specific positions of the wireless tags 12 of all the acquired tag IDs. Obtained from the result table 131d (step SE-4).

  Next, the position correspondence control unit 130d identifies the tag ID of the wireless tag 12 registered as the product of the store that requested the display (step SE-5). This specification is performed by, for example, transmitting the name of the display request source store when receiving the display request and referring to the store tag ID correspondence table 131g based on the name. At this time, when the store non-specific flag 1 is stored in the store tag ID correspondence table 131g, the tag ID associated with the store non-specific flag 1 is also a tag ID for displaying information. Or you may make it include tag ID linked | related with the said store non-specific flag 1 only when the item linked | related with the said store non-specific flag 1 is contained in the item of the store of the said display request origin. Further, the position correspondence control unit 130d refers to the competition relationship table 131i based on the name of the display request source store that is transmitted when the display request is received, so that the position correspondence control unit 130d has a competitive relationship with the display request source store. Identify the name of a store. And the position corresponding | compatible control part 130d acquires the position (purchasing area) of the said store in the said competitive relationship with reference to the purchase area specific table 131e based on the name of the said store in the said competitive relationship (step SE-). 6).

  Next, the position correspondence control unit 130d checks whether or not the specific position of the wireless tag 12 is within a predetermined distance (for example, 5 m) from the purchase area and the purchase area of the store in a competitive relationship (step SE). -7). If the specific position of the wireless tag 12 is within a predetermined distance from the purchase area of the store in a competitive relationship (step SE-7, Yes), the notification is made to the store terminal 14 that is the display request source. A signal to the effect is transmitted (step SE-8). The store terminal 14 that has received the signal for notification notifies the notification sound that the customer who owns the wireless tag 12 of the product of the store is within a predetermined distance from the purchase area of the store in a competitive relationship with the speaker. Or output means such as a display screen. Accordingly, the store clerk of the store terminal 14 that is the display request source can detect that a customer who has planned to purchase a product at another store (competitor store) is in the purchase area of the store, Appropriate measures such as recommending store products can be taken. On the other hand, in step SE-7, when the specific position of the wireless tag 12 is not within a predetermined distance from the purchase area and the purchase area of the store in a competitive relationship (step SE-7, No), this processing is performed. Is not done.

  Next, the position correspondence control unit 130d superimposes and displays the icons of all tag IDs on the layout image of the entire shopping mall on the position corresponding to the specific position of the tag ID. The image is transmitted to the display request source store terminal 14 via the communication processing unit 130c (step SE-9). Here, with respect to the position of the wireless tag 12 corresponding to the product of the display request source store among all the wireless tags 12, it is preferable to arrange icons having different display forms from the wireless tags 12 of other stores.

  In the store terminal 14 that is the display request source, the store clerk displays the layout image on which the icons are arranged on an output means such as a display screen, whereby the store clerk visually grasps the position of the wireless tag 12 corresponding to the product in the store. can do. FIG. 16 is a schematic diagram illustrating an example of a layout image of the entire shopping mall in which the position of the wireless tag 12 is indicated by an icon. In FIG. 16, an icon 12a indicates the position of the wireless tag 12 corresponding to the product of the store from which the display is requested, and other icons such as the icon 12b indicate the position of the wireless tag 12 corresponding to the product of a store other than the store. ing.

  Thereafter, the store clerk of the display request source store can request an enlarged display of the store by designating the store in the layout image of the shopping mall displayed on the store terminal 14 of the store. For example, the store terminal 14 is provided with an input unit (not shown). By performing a predetermined operation for designating the store in the layout image via the input unit, an instruction for an enlarged display is given to the communication processing unit 130c. Sent.

  When the communication processing unit 130c receives an enlargement display instruction from the store terminal 14 (step SE-10), the position correspondence control unit 130d is based on the name of the enlargement instruction source store transmitted together with the enlargement display instruction. By referring to the purchase area specifying table 131e, the location of the store of the enlargement instruction source is acquired, the file name of the layout image of the store of the enlargement instruction source is acquired, and the layout DB 131f is stored based on this file name. By referencing, a layout image of the enlargement instruction source store is acquired (step SE-11). Then, the position correspondence control unit 130d is in the enlargement instruction source store based on the specific position of each wireless tag 12 in the position specification result table 131d and the acquired position of the enlargement instruction source store. The wireless tag 12 is specified, the position of the specified wireless tag 12 is superimposed on the corresponding position in the acquired layout image of the store of the enlargement instruction source, and the layout image is transmitted to the store terminal 14 (step SE-12). Also at this time, regarding the position of the wireless tag 12 corresponding to the product of the store of the enlargement instruction source, it is preferable to arrange an icon having a display form different from the wireless tag 12 corresponding to the product of the other store.

  In the store terminal 14 in the store of the enlargement instruction source, the layout image of the store in which the icon is arranged is displayed on an output means such as a display screen, whereby the position of the wireless tag 12 in the store is determined. The position of the wireless tag 12 corresponding to the product can be visually grasped. FIG. 17 is a schematic diagram illustrating an example of a store layout image in which the position of the wireless tag 12 is indicated by an icon. In FIG. 17, an icon 12a indicates the position of the wireless tag 12 corresponding to the product of the own store, and other icons such as the icon 12b indicate the position of the wireless tag 12 corresponding to the product of the store other than the own store. Therefore, the store clerk of the store terminal 14 that is the enlargement instruction source can specify in detail the position of the customer who planned to purchase the product at the store, and by directly dealing with the customer, Increase the success rate of sales.

  Thereafter, the store clerk of the expansion instruction source store further specifies the tag ID of the icon of the wireless tag 12 corresponding to the product of the store from the store terminal 14, etc. It is possible to request the display of the movement route in the shopping mall 2. For example, the store terminal 14 is provided with an input unit (not shown), and a predetermined operation for designating one of the wireless tags 12 in the store displayed on the enlarged layout image is performed via the input unit. Thus, a request for moving route display is transmitted to the communication processing unit 130c.

  When the communication processing unit 130c receives a request for displaying a travel route from the store terminal 14 (step SE-13, Yes), the position correspondence control unit 130d obtains travel route data for the specified tag ID from the storage unit 131. It acquires (step SE-14) and transmits the acquired travel route data to the requesting store terminal 14 (step SE-15). Thereby, in the store terminal 14, it becomes possible to display a movement path | route with the display form shown in FIG. Therefore, the store clerk of the requesting store terminal 14 can grasp in detail the latest trends of the customers who have visited the store, and by taking into account these trends, the customer can successfully sell the product. The rate can be increased.

(Effect of Embodiment 1)
As described above, according to the first embodiment, the approximate position of the wireless tag 12 is determined based on the access point ID transmitted from the access point 10 and the signal strength of the estimation information received by the wireless tag 12. Can be estimated. When the wireless tag 12 is located within the specific range, the estimated position of the wireless tag 12 is corrected based on the tag writer ID for the tag writer 11 corresponding to the specific range, and a more accurate position is specified. be able to. Therefore, by arranging the tag writer 11 only in an area where the position needs to be specified in detail, the position of the wireless tag 12 positioned within the specific range corresponding to the tag writer 11 can be specified accurately. In addition, in the region where the position only needs to be roughly grasped, the position of the wireless tag 12 can be estimated without arranging the tag writer 11, so that the position of the object is specified in detail uniformly. Thus, the necessary cost can be reduced.

  In particular, the position correspondence control unit 130d determines the position of the wireless tag 12 held by the customer indicating the purchase intention in the purchase area where the customer holding the specified wireless tag 12 indicates the purchase intention. Since the store image is output on the store terminal 14 in association with the layout image, the store clerk of each store can grasp the current position of the customer who has a purchase intention in the purchase area of the store more visually. For this reason, it is possible to grasp the purchase psychology stage of customers who have a purchase intention in the purchase area of their own store, and appropriate sales response according to the current position to the customer showing the purchase intention Can be taken.

  In addition, the position correspondence control unit 130d determines that the position of the wireless tag 12 held by a customer indicating a purchase intention in a specific purchase area is different from other purchase areas that are in a competitive relationship with the specific purchase area. The position of the wireless tag 12 and the alarm that the position of the wireless tag 12 is within the predetermined distance are output to the store terminal 14, so that the store clerk at each store Appropriate sales responses can be taken in consideration of competitors for customers who are willing to purchase in the purchasing area.

  Further, the position correspondence control unit 130d displays the position of the customer indicating the purchase intention in the specific purchase area on the enlarged layout image of the purchase area. The position of the customer who was planning to purchase the product can be specified in detail, and the customer service direct response to this customer can increase the success rate of the product sales.

  Further, the position correspondence control unit 130d outputs the travel route of the customer who owns the wireless tag 12 in the shopping mall to the store terminal 14, so that the store clerk of each store can purchase in the purchase area of the store. The customer's preference and buying route can be confirmed, and an appropriate sales response corresponding to the moving route can be taken with respect to the customer who indicates purchase intention.

[Embodiment 2]
Next, a second embodiment will be described. In the second embodiment, the mobile phone owned by the audience of the cinema complex is targeted, the location of this mobile phone is specified by an access point and a tag writer, and the position corresponding control device determines the location of the mobile phone based on the location of the mobile phone. In this mode, a control signal for switching the mode is transmitted to the mobile phone, and the mode is automatically switched by the mobile phone itself.

The specific processing is the same as that of the first embodiment except that the tag ID is used.

  The communication processing unit 130c controls communication with the access point 10, and is configured as a network board, for example.

  The position correspondence control unit 301d determines whether or not the position of the mobile phone 20 identified by the identification processing unit 130b is a manner area and whether or not the strict mode is to be applied in the manner area. As necessary, mode change information to be transmitted to the mobile phone 20 is generated. This mode change information is information for instructing the mobile phone 20 to switch modes. Details of the position correspondence control process and the mode change information will be described later.

(Configuration of position control device-storage unit)
The storage unit 302 is a storage unit for storing data necessary for executing each process in the position correspondence control device 30. The storage unit 302 stores a signal strength DB 131a, a measured signal strength DB 131b, a tag writer arrangement table 131c, a mode control table 302b as control content related information, and an access point table 302g. The structures of the signal strength DB 131a, the signal strength actual measurement DB 131b, and the tag writer arrangement table 131c are the same as those in the first embodiment. Although the specific configuration of the storage unit 302 is arbitrary, for example, the storage unit 302 is configured by a non-volatile storage device such as an HD.

  FIG. 21 is a table showing the data structure of the mode control table 302b. The mode control table 302b is configured by associating setting mode change coordinates, setting mode setting contents, strict mode change coordinates, strict mode setting contents, and setting mode and strict mode duration. The setting mode change coordinates indicate a position range where the mode of the mobile phone 20 should be changed to the setting mode. For example, the record in the first line in FIG. 21 indicates that when the mobile phone 20 is located in an area from From = (4, 5) to To = (12, 14), the mode of the mobile phone 20 is set to set mode = manner. Indicates that the mode is set for 60 minutes only. The strict mode change coordinates indicate a position range where the mode of the mobile phone 20 should be changed to the strict mode. Here, the strict mode change coordinates are set so as to be included in the setting mode change coordinates. For example, the record in the first line in FIG. 21 shows that when the mobile phone 20 is located in an area from From = (8, 8) to To = (10, 12), the mode of the mobile phone 20 is strictly set from the setting mode. Mode = Shows that the power is turned off for only 60 minutes. Thus, by setting a plurality of modes in overlapping position ranges, when the mobile phone 20 is brought into a specific area, the mode is changed to the setting mode, and further, the mobile phone 20 is placed in a specific area within the area. When brought in, the mode can be changed to a strict mode that is stricter than the setting mode, and the mode of the mobile phone 20 can be changed in multiple stages. Actually, a plurality of mode control tables 302b configured as described above are held according to the number of cinema complexes 4 covered by the position corresponding control system, and the mobile phone 20 is selected from the plurality of mode control tables 302b. One mode control table 302b matching the current position is selected and used, but only one mode control table 302b is shown in FIGS.

  FIG. 22 is a table showing the data structure of the access point table 302g. The access point table 302g is configured by associating an access point ID for uniquely identifying each access point 10 with position coordinates indicating an area in which each access point 10 is responsible. For example, the record on the first line in FIG. 22 indicates that the access point 10 with access point ID = AP001 is responsible for the area from From = (0, 0) to To = (19, 19).

  FIG. 23 is a diagram illustrating a data structure of mode change information generated by the position correspondence control unit 301d. The mode change information is control data for instructing the mobile phone 20 to change the mode, and includes the MAC address of the mobile phone 20, the mode type, and the duration.

(Processing operation of position control system)
Next, the processing operation of the position correspondence control system 3 will be described. FIG. 24 is a sequence diagram showing a flow of communication and processing between the mobile phone 20 and the position corresponding control apparatus 301 constituting the position corresponding control system 3.

  Estimated information including the access point ID of the access point 10 is transmitted from the access point 10 to the entire area of the cinema complex 4, and the estimated information is received by the mobile phone 20 held by the audience. When the cellular phone 20 receives the estimation information by the reception unit 201 (step SF-1), the cellular phone 20 stores the content of the received estimation information in the storage unit 205. In addition, the signal strength measuring unit 202 measures the signal strength of the received estimated information, and stores the signal strength information for specifying the measured signal strength in the storage unit 205.

  Further, when the spectator approaches the area where the tag writer 11 is installed and the spectator enters the specific range corresponding to the tag writer 11, the mobile phone 20 receives specific information including the tag writer ID of the tag writer 11 from the tag writer 11. The content of the received specific information is stored in the storage unit 205. The control unit 204 of the mobile phone 20 has a manner area as shown in FIG. 20 including the MAC address of the mobile phone 20, the access point ID included in the estimation information, the signal strength of the estimation information, and the tag ID included in the specific information. Discrimination information is generated (step SF-2), and the manner area discrimination information is transmitted to the access point 10 via the transmission unit 203 (step SF-3).

  This manner area discrimination information is input from the receiving unit 101 of the access point 10 to the communication processing unit 130 c of the position corresponding control device 30. When the manner area discrimination information is input, the communication processing unit 130c stores the manner area discrimination information in the signal strength DB 131a together with a time stamp indicating the time when the reception unit 101 receives the information (step SF). -4).

  Next, the estimation processing unit 301a refers to the signal strength DB 131a and the signal strength actual measurement DB 131b, and executes the estimation processing similar to FIG. 12 based on the information stored in the signal strength DB 131a and the like, so that the mobile phone 20 Is estimated (step SF-5). Subsequently, the specific processing unit 301b executes the specific processing similar to that in FIG. 13 based on the position of the mobile phone 20 estimated by the estimation processing unit 301a and the tag ID stored in the signal strength DB 131a. The position of the telephone 20 is specified (step SF-6). When the position of the mobile phone 20 is specified, the mode control table 302b is referred to based on the specified position of the mobile phone 20, and the position of the mobile phone 20 is included in the setting mode change coordinates and the strict mode change coordinates. Determine whether or not. At this time, one mode control table 302b including the specified position coordinates of the mobile phone 20 is selected from a plurality of mode control tables 302b stored in the storage unit 302 and used. If the position correspondence control unit 301d determines that the position of the mobile phone 20 is included, the position correspondence control unit 301d stores the setting mode and duration stored in association with the setting mode change coordinates in the mode control table 302b, or the strict mode. The strict mode and duration stored in association with the change coordinates are acquired, and using these, mode change information as shown in FIG. 23 is generated (step SF-7).

  Then, the position correspondence control unit 301d refers to the access point table 302g based on the position of the mobile phone 20 specified in the specifying process, and thereby the access point ID of the access point 10 in charge of the position of the mobile phone 20 To get. When the previously generated mode change information is transmitted to the access point 10 via the communication processing unit 130c, the mode change information is transmitted to the mobile phone 20 via the access point 10 (step SF- 8).

  In the mobile phone 20 that has received the mode change information from the access point 10, the control unit 204 performs a mode change or power-off operation according to the mode change information (step SF-9). Specifically, the control unit 204 of the mobile phone 20 stops the operation of the position detection based on the radio wave from the access point 10 and the generation process of manner area discrimination information for the duration set by the mode change information. And a control part confirms the mode set to the mobile telephone 20, and judges whether it is the same as the mode classification designated by mode change information. If they are the same, the mode is not changed. When the current mode is not the same as the mode type specified in the mode change information and the mode type specified in the mode change information is power OFF, the control unit 204 operates the automatic power OFF function to turn off the power. Execute. If the mode type specified in the mode change information is not turned off, the mode is changed to a specified mode (such as manner mode). Note that a terminal control function preinstalled in the mobile phone 20 is used for mode change and power-off control.

  In this process, in this embodiment, as shown in FIG. 18, when a spectator enters the cinema complex 4, the mobile phone 20 held by the spectator is automatically switched to at least the setting mode. In particular, since the tag writer 11 is installed at the entrance of each movie theater, when entering each movie theater, the mobile phone 20 is switched to the setting mode by the tag ID received from the tag writer 11, and further, the strict mode. Is switched to. For example, when the power of the mobile phone 20 is automatically turned off in the strict mode, the power is turned off while the mobile phone 20 is showing the movie by making the duration in the strict mode correspond to the movie showing time. Thus, it is possible to perform automatic control reflecting the needs of the movie theater and the convenience of the audience, such as automatically turning on the power after the screening.

  Note that FIG. 18 is merely an example. For example, even within the same movie theater, the tag writer 11 placed near the audience seat in the center of the movie theater turns off the mobile phone 20 of the audience in the center audience. The tag writer 11 placed in the vicinity of the entrance near the entrance in the movie theater performs detailed switching control according to the location of the audience, such as allowing only the mobile phone 20 of the audience at the entrance near the entrance. It becomes possible. Also, by providing a plurality of mode control tables 302b, it is possible to control the mode of the mobile phone 20 according to the needs of each place not only in the cinema complex 4, but also in various facilities and places such as in trains and hospitals. It becomes. For example, as an example of mode setting in the plurality of mode control tables 302b, in a train, the manner mode is set in all areas and the power is turned off in the area near the silver sheet, and in the hospital, in the lobby or cafe corner. In the event hall, the manner mode can be set and the manner mode can be set in the hall and the meeting mode can be set in the conference room.

(Effect of Embodiment 2)
As described above, in the second embodiment, it is possible to cause the mobile phone itself to perform appropriate correspondence and control according to the position specified by the tag writer 11 and the access point 10. In particular, in the present embodiment, it is determined whether the mobile phone is in a manner area or a strict area based on the position of the mobile phone, and mode change information including a mode switching instruction and a power-off instruction is sent from the position corresponding control device 301. Since it is transmitted to the mobile phone 20, in the manner area, avoid forgetting to artificially switch the mobile phone to the manner mode, lack of manner consciousness, etc., and improve manners when using the mobile phone Can be planned.
