In the case of automatic ticket gates, passports and commuter passes held by passers-by, passers in passports or restrictions are identified by identifying tickets etc. in the case of gates such as halls and halls. IC cards that are rapidly increasing in number have been used for tickets and tickets, etc., and there are some that use ticket tags and tickets etc. without taking them out of the wallet etc., but using IC tags as well as IC cards Thus, a method for allowing a passer-by to pass without taking out a ticket or a ticket from a pocket or a bag, that is, a passage control system (access control system) has been proposed.

  For example, according to Patent Document 1, a communication medium that can be communicated by a passerby passing through a traffic monitoring area such as a ticket gate is detected, and the entire traffic monitoring area is photographed by a camera, and the detected traffic is detected. A traffic monitoring method and equipment for monitoring a passerby have been proposed based on information on a medium and information on a captured image.

  In addition to the invention disclosed in Patent Document 1, wireless areas are provided on the entrance side and the exit side of the ticket gate as disclosed in Patent Document 2, and identification information such as a ticket held by a passerby is provided. There has been proposed an automatic ticket gate device that allows a passer-by to pass based on the number of times of reception of identification information in two wireless areas, continuously acquired by a receiver. This automatic ticket gate is also provided with a plurality of sensors for detecting traffic, and the traffic is controlled by associating the number of times the identification information is received with the position information detected by the sensor.

Further, according to Patent Document 3, when the optical sensor detects a passerby entering the ticket gate, it uses a plurality of transceivers to continuously send and receive signals to and from the passerby's wireless card and detect the position of the wireless card. A wireless automatic ticket gate for performing ticket gates has been proposed.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  The automatic ticket gate system according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram showing a configuration of an automatic ticket gate system according to an embodiment of the present invention.

  In the automatic ticket gate system 100 shown in FIG. 1, automatic ticket gate bodies 102a to 102f, tag detection fixed stations 103a to 103d, and passage reference wireless tags 104a to 104h are arranged in a predetermined area 101. The automatic ticket gates 102a to 102f automatically handle the ticket gates based on the identification information (identification IDs) of the passer-by wireless tags 107a and 107b, for example, which are incorporated in the small plastic cases or the like possessed by the passers-by 106a and 106b. Is what you do. For example, a pair of automatic ticket gates 102a and 102b functions as one automatic ticket gate.

  Passages 105a to 105c are formed between the two automatic ticket gate bodies. The passages 105a to 105c are for the passers-by 106a and 106b to pass, and have such a width that the passer-by 106 can pass one by one. Further, by providing a door on the passage side of the automatic ticket gate main body, for example, on the passage side of the automatic ticket gate main bodies 102a and 102b, when the passage of the passer-by 106a is not permitted, the door can be closed to prevent the passage. . Although three automatic ticket gates are installed in the predetermined area 101 in the figure, any number can be installed according to the number of passengers at the station.

  The tag detection fixed stations 103a to 103d are arranged so that the entire predetermined area 101 is a wireless area. Passage reference wireless tags 104a to 104h arranged in the predetermined area 101 and passerby wireless tags 107 possessed by the passersby 106 are provided. It is to detect. Although the passage reference wireless tag is not shown in the passage 105b, a passage reference wireless tag is disposed in the same manner as the passages 105a and 105c. Since a plurality of automatic ticket gates are installed side by side in the predetermined area 101, the passage reference wireless tags 104a to 104h and the passerby wireless tag 107 are separated from the tag detection fixed station 103 by, for example, several meters to several tens of meters. A device that can perform wireless communication and can provide position information is used.

  The passage reference wireless tags 104a to 104h are arranged two by two on the devices of the automatic ticket gate main bodies 102a to 102f. The passage reference wireless tags 104a to 104h are wireless tags having the same characteristics as the passer-by wireless tag 107 possessed by the passer-by 106, and the position information of the passer-by wireless tag 107 is corrected to change the position of the wireless tag. It is arranged to suppress. By using a wireless tag having the same characteristics as the passer-by wireless tag 107, it is possible to accurately suppress position fluctuations of the passer-by wireless tag 107.

  The passage reference wireless tag 104 is not limited to the above-described arrangement method. For example, the passage reference wireless tag 104 is arranged one by one in the center of each area of the passage 105, or the path is on a diagonal line of each area of the passage 105. Two reference wireless tags 104 can be arranged. Furthermore, if the passages 105a to 105c are combined into one passage group region, the passage reference wireless tags 104 are arranged one by one at the four corners of the passage group region, or the passage reference wireless tag 104 is located at the center of the passage group region. It is also possible to arrange one or two passage reference wireless tags on the diagonal line of the passage group region.

  Besides, the passage reference wireless tag 104 is arranged on the wall of the automatic ticket checker for forming the passage, for example, on the wall corresponding to the automatic ticket checker, on the floor surface of the passage 105 or the like. It can be embedded under the floor of the passage 105. Regardless of the arrangement method, it is possible to suppress the above-described positional fluctuation.

  Further, a passer-by detector 150 is provided in the vicinity of the passage 105a. The passer-by detector 150 is for detecting the position of the passer-by 106. Although not shown in the passages 105b and 105c, a passer-by detector 150 is provided similarly to the passage 105a. A management device 200 is provided near the predetermined area 101. The management device 200 passes the passerby 106 based on signals from the passage reference wireless tag 104 and the passerby radio tag 107 detected from the tag detection fixed stations 103a to 103d and a detection signal output from the passer detector 150. It is for judging permission. The management device 200 is connected to the tag detection fixed stations 103a to 103d, the passer-by detector 150, and the automatic ticket gate main bodies 102a to 102f by cables or wirelessly.

  Subsequently, a detection area of a passerby in the passage will be described with reference to FIGS. 2 and 3. FIG. 2 is a schematic view showing a passerby detection area in the passage, and FIG. 3 is a schematic view showing a passerby detection area in the passage using a plurality of passer detectors.

  A passer-by detector 150 is provided in the vicinity of the passage 105 shown in FIG. 2, and the area of the passage 105 is divided into detection areas A to C to detect the position of the passerby. The detection area A is an area for detecting a passerby existing on the entrance side of the passage 105 where the passerby 106 exists, the detection area B is an area for detecting a passerby who has moved in the passage, and the detection area C is a passageway. This is an area for detecting a passerby existing on the exit side 105.

  The automatic ticket gate main bodies 102a and 102b are provided with a non-detection area between the detection area B and the detection area C so that a door can be provided to permit or deter passage of the passerby 106. It has been. Further, in the detection area B before this non-detection area, the pass permission of the passer-by 106 is actually determined based on the identification information of the passer-by radio tag 107. Detection areas A to C in the passage 105 are set asymmetrically on the inlet side and the outlet side.

  The passer-by detector 150 that detects the position of the passer-by 106 is, for example, the position of the passer-by 106 using a galvanomirror device as disclosed in Japanese Patent Laid-Open No. 2006-350765 filed earlier by the present applicant. A device for detecting the above is used. Light rays output from the light emitters provided on the automatic ticket checker main bodies 102 a and 102 b and the wall near the passage 105 are reflected through the galvanometer mirror and the reflecting mirror provided near the ceiling of the passage 105. The galvanometer mirror drive control means drives the galvanometer mirror in two axial directions so that this light beam scans the entire path. The light reflected from the passage 105 or the passerby 106 is received by the light receiver again through the reflecting mirror and the galvanometer mirror. Based on the time difference until the light emitted from the light emitter is received by the light receiver, the position of the passerby 106 existing in the passage 105 is detected.

  Alternatively, the position of the passer-by 105 may be detected by reflecting a light beam output from a light emitter arranged near the passage through a galvano mirror without using a reflecting mirror. Furthermore, in addition to the human detector using the galvanomirror device, a human detector using an imaging device such as a camera or an optical sensor may be used. The position of the passer-by 106 can be specified by taking an image of a passer-by passing through the passage 105 with the imaging device and analyzing the image. In addition, it is possible to detect the passing state of the passer-by 106 by arranging reflective human detectors in a line on the side face of the automatic ticket gate main body 102a, 102b on the passage side. Note that the number of passerby detectors provided in the passage 105 is not limited to one. As shown in FIG. 3, a plurality of passer-by detectors 150a and 150b are provided in the vicinity of the passage 105, and the passers-by detectors 150a and 150b detect the positions of the passers-by 106 existing in the detection areas A to C. Also good.

  Next, with reference to FIG. 4, the possible range of the wireless tag possessed by the passerby 106 will be described. FIG. 4 is a schematic diagram showing the possible range of wireless tags possessed by passers-by.

  When a passer-by 106 is detected in the above-described detection areas A to C of the passage 105, the actual location of the passer-by wireless tag 107 possessed by the passer-by 106 is based on the accuracy of the wireless tag and the passer-by 106. A slight error occurs depending on how the wireless tag 107 is held. For this reason, when specifying the position information of the passer-by radio tag 107, it is necessary to consider this error.

  A predetermined distance Rt from the presence position of the passer-by radio tag 107 is set to a distance Rd from the center position O (evaluation point) of the passer-by person 106 to the presence position of the passer-by radio tag 107 possessed by the passer-by 106. A wireless tag existence possible range 108 having a radius of the added distance Re is assumed. And the identification information of all the radio | wireless tags which exist in this existence possible range 108 is made into the candidate of the passer-by radio tag 107 which the passer-by 106 possesses.

  As described above, a passerby tag 107 is detected in the detection areas A to C, and the passerby radio tag 107 existing in the possible range 108 of the passerby radio tag 107 is detected based on the detected position of the passerby 106. As a candidate, a detection object ID matching process for matching the position of the passer-by 106 and the position of the passer-by wireless tag 107 is performed.

  Subsequently, a detection area of the passer-by wireless tag 107 in the passage 105 will be described with reference to FIGS. 5 and 6. FIG. 5 is a schematic diagram showing an entrance / exit detection area of a passerby radio tag in the passage, and FIG. 6 is a schematic view showing an in-passage detection area of the passerby radio tag in the passage.

  The passage 105 shown in FIG. 5 is the same as the passages 105a to 105c shown in FIG. An entrance detection region 110 is provided on the side that becomes the entrance of the passage 105. For example, the position information of the passer-by wireless tag 107c existing in the passage 105 can be the position information within the range 109a due to the error of the position information of the wireless tag described above. Similarly, the position information of the passer-by radio tags 107d to 107f can take the position information within the range 109b to 109d. In this way, the entrance detection area 110 is provided so as to include all the areas 109b to 109d in consideration of the error of the position information of the passerby radio tag 107.

  In addition, an exit detection area 111 is provided on the side opposite to the entrance detection area 110 of the passage 105, that is, on the side serving as the exit. The position information of the passer-by radio tags 107g to 107j existing near the exit of the passage 105 can be the position information within the range 109e to 109h. In the same manner as the entrance detection area 110, the exit detection area 111 is provided so as to include all the areas 109e to 109h in consideration of errors in the position information of the passerby radio tag 107.

  The passage 105 shown in FIG. 6 is the same as the passages 105a to 105c shown in FIG. Although not shown, this passage 105 is provided with the above-described entrance detection area 110 and exit detection area 111. The position information of the passer-by wireless tags 107k to 107n existing between the vicinity of the entrance and the exit of the passage 105 can be the position information within the ranges 109i to 109l. In the same manner as the entrance detection area 110 and the exit detection area 111, the in-passage detection area 112 is provided so as to include all the areas 109i to 109l in consideration of the positional information error of the passer-by wireless tag 107.

  As described above, the passage 105 is provided with the three detection regions of the entrance detection region 110, the exit detection region 111, and the in-passage detection region 112. In each of the detection areas of the entrance detection area 110, the exit detection area 111, and the in-passage detection area 112 provided in the passage 105, the update time and the entrance detection area 110 are added to the information of the passer-by wireless tag 107 detected in the passage 105. A passage ID matching process is performed in which information such as the state of the entrance detection area flag indicating that the passerby radio tag 107 is present is added and managed as an ID list. This passage ID matching process is performed in order to further improve the accuracy of the detection object ID matching process described above.

It is. For example, the position of the passer-by 106 is specified based on the relative distance between the position information of the passer-by wireless tag 107 and the position information of the passage reference wireless tag 104, or the deviation of the position information of each passage reference wireless tag 104 is averaged. By correcting the area where the passage reference wireless tag 104 is arranged linearly, the position of the passerby 106 can be specified with high accuracy.

  The wireless tag identification information acquisition unit 204 acquires wireless tag identification information from the signals of the passer-by wireless tag 107 and the passage reference wireless tag 104 analyzed by the wireless tag signal processing unit 201. The identification information list storage unit 205 includes the position information of the passer-by wireless tag 107 and the position information of the passage reference wireless tag 104 output from the passer-by position determination unit 203, and the passerby output from the wireless tag identification information acquisition unit 204. The identification information of the wireless tag 107 and the identification information of the passage reference wireless tag 104 are stored as an ID list.

  When the passer-by wireless tag 107 is detected, the passer-by wireless tag 107 exists in the position information (existing position), update time, and entrance detection area 110 of the wireless tag using the identification information of the passer-by wireless tag 107 as a key. A record consisting of the state of the entrance detection area flag indicating that it has been stored is stored in the ID list. This ID list is provided for each passage.

  The passer-by position signal processing unit 206 analyzes the signal output from the passer-by detector 150 and outputs position information of the passer-by 106.

  The matching processing unit 207 associates the position information of the passer-by radio tag 107 stored in the identification information list storage unit 205 with the position information of the passer-by 106 output from the passer-by position signal processing unit 206 (detection target).

The separation distance calculation unit 207a calculates the separation distance between the position information of the passer-by wireless tag 107 stored in the identification information list storage unit 205 and the position of the passer-by 106 output from the passer-by position signal processing unit 206. Is. The accuracy determination unit 207b determines the priority for performing the above-described association based on the separation distance calculated by the separation distance calculation unit 207a. This priority is set higher, for example, as the distance is closer, and lower as the distance is longer.

  The matching list storage unit 208 includes a position (evaluation point) of the passer-by 106 detected by the passer-by detector 150, identification information of the passer-by wireless tag 107 within the possible range 108 from the evaluation point, and a separation distance calculation unit 207a.

The wireless tag identification number storage unit 209 stores an identification number of the wireless tag and data such as a passage authority corresponding thereto. The data such as traffic authority is information such as adult / child distinction, boarding section, commuter pass validity period, and the like.

  The passage permission determination unit 210 outputs the matching passer's position information and identification information output from the matching processing unit 207, data such as passage authority corresponding to the identification information stored in the wireless tag identification number storage unit 209, and Based on the above, the pass permission determination result of the passer-by 106 is output.

  Next, the flow of the detection object ID matching process in which the matching processing unit 207 matches the position of the passerby 106 and the position of the passerby wireless tag 107 will be described with reference to FIG. FIG. 8 is a flowchart showing a flow of detection object ID matching processing of the matching processing unit.

  When the passer-by detector 150 detects the position of the passer-by 106 (step S251) and detects the passer-by 106 present in the detection area A (YES in step S252), the matching processing unit 207 displays the identification information list. From the ID list stored in the storage unit 205, the records (identification information, position information) of all passerby radio tags 107 existing in the possible range 108 of the passerby radio tags 107 with reference to the evaluation points shown in FIG. Etc.) is acquired (step S253).

  The separation distance calculation unit 207a calculates the separation distance between the two positions from the position information of the passerby 106 and the position information of the passerby wireless tag 107. In addition, the accuracy determination unit 207b determines the accuracy of matching in order from the shortest distance, and updates the matching list stored in the matching list storage unit 208 (step S254).

  When the passerby 106 existing in the detection area B is detected (YES in step S256), the matching processing unit 207 refers to the matching list and uses the position of the passerby 106 as a reference with the highest accuracy. The position of the passer-by radio tag 107 is matched with the position information of the passer-by 106 (step S257). Then, the pass permission determination unit 210 executes a process according to the authority corresponding to the identification information of the matched passer wireless tag 107 (step S258). This process is a passage permission / prohibition, for example, a process of opening / closing a door of an automatic ticket gate. When this process is completed, the process returns to step S251 to repeat the process.

  When the passerby 106 existing in the detection area C is detected (YES in step S259), the matching processing unit 207 deletes the record of the information about the passerby radio tag 107 of the passerby 106 from the matching list ( Step S260), returning to step S251, the process is repeated.

  As described above, the position of the passerby 106 existing in the detection areas A to C is continuously detected at an arbitrary time interval, and the passerby wireless tag 107 can be present on the basis of the detected position of the passerby 106. Information on all the passer-by radio tags 107 existing in the range 108 is acquired, and the position of the passer-by radio tag 107 having the highest accuracy is matched with the position of the passer-by radio tag 107.

  In order to further improve the matching accuracy between the passerby 106 and the passer-by wireless tag 107 in the detection object ID matching process described above, in addition to the detection object ID matching process, the entrance detection area 110 and the exit provided in the passage 105 In each detection region of the detection region 111 and the detection region 112 in the passage, passage ID matching processing is performed in which information such as an entrance detection region flag is added to the identification information and position information of the passer-by wireless tag 107 detected in the passage 105.

  The flow of the passage ID matching process will be described with reference to FIGS. 9 is a flowchart showing the flow of processing when a passerby radio tag is detected, FIG. 10 is a flowchart showing the flow of entrance detection area tag processing, and FIG. 11 shows the flow of detection area tag processing in the passage. FIG. 12 is a flowchart showing the flow of exit detection area tag processing, and FIG. 13 is a flowchart showing the flow of area tag processing outside the passage.

  The passerby wireless tag 107 is detected (step S301), and the wireless tag position information acquisition unit 202 acquires the presence position of the passerby wireless tag 107 (step S302). When the passer-by wireless tag 107 is detected in the entrance detection area 110 (YES in step S303), the identification information list storage unit 205 performs entrance detection area tag processing shown in FIG. 10 (step S304).

  In the entrance detection area tag processing shown in FIG. 10, the identification information list storage unit 205 first sets an entrance detection area flag indicating that the passer-by wireless tag 107 exists in the entrance detection area 110 (step S401). Subsequently, a passage is specified based on the position information of the passer-by wireless tag 107, and an ID list provided for each passage is selected (step S402). Then, a new record of the tag location, update time, and entrance detection area flag state is added to the selected ID list using the identification information of the passerby radio tag 107 as a key. If the identification information of the wireless tag is already registered in the detected ID list, only the tag location and the update time may be updated (step S403).

  If the passerby radio tag 107 is detected in the in-passage detection area 112 (YES in step S305), the in-passage detection area tag process shown in FIG. 11 is executed (step S306).

  In the in-passage detection area tag processing shown in FIG. 11, the identification information list storage unit 205 selects an ID list for each passage based on the detected position information of the passer-by wireless tag 107 (step S421). If the entrance detection area flag of the record corresponding to the passer-by radio tag 107 is not set with reference to the ID list (NO in step S422), the passer-by 106 who owns the passer-by radio tag 107 will enter the entrance detection area. Since there is a possibility of not passing through 110, the processing is terminated as it is. If the entrance detection area flag is set (YES in step S422), the location and update time of the passer-by wireless tag 107 stored in the ID list are updated (step S423).

  If the passer-by radio tag 107 is detected in the exit detection area 111 (YES in step S307), the exit detection area tag process shown in FIG. 12 is executed (step S308).

  In the exit detection area tag processing shown in FIG. 12, the identification information list storage unit 205 selects an ID list for each passage based on the detected position information of the passer-by radio tag 107 (step S441). If the entrance detection area flag of the record corresponding to the passer-by radio tag 107 is not set with reference to the ID list (NO in step S442), the passer-by 106 who owns the passer-by radio tag 107 will be in the entrance detection area. Since there is a possibility of not passing through 110, the processing is terminated as it is. If the entrance detection area flag is set in the passer-by radio tag 107 (YES in step S442), the record corresponding to the passer-by radio tag 107 is deleted from the ID list. By deleting the record, the entry detection area flag, the position information, and the update time information of the identification information of the passerby radio tag 107 are deleted (step S443).

  When the passer-by radio tag 107 is detected in an area that is not any of the entrance detection area 110, the exit detection area 111, or the in-passage detection area 112 (YES in step S309), the outside-passage area tag processing shown in FIG. 13 is performed. Execute (Step S310).

  In the outside passage area tag processing shown in FIG. 13, the identification information list storage unit 205 selects all the ID lists for each passage (step S461). With reference to the ID list, if the update time of the record corresponding to the passer-by radio tag 107 has passed a predetermined time (YES in step S462), the passer-by 106 may have already passed the passage. Since the property is high, the record of the passer-by wireless tag 107 is deleted (step S463).

  If the predetermined time has not elapsed since the update time (NO in step S462) and the entrance detection area flag is not set (NO in step S464), the passer-by wireless tag before entering the entrance detection area 110 107, and there is a possibility of entering the entrance detection area 110, so the processing is terminated as it is. When the entrance detection area flag is set (YES in step S464) and the identification information of the passerby radio tag 107 does not exist in the matching list (NO in step S465), the detection is detected in the detection area A of the passage 105. Because there is a possibility that it is just before the processing, the processing is terminated as it is.

  If the entrance detection area flag is set (YES in step S464) and the identification information of the passerby radio tag 107 exists in the matching list (YES in step S465), the passerby 106 enters the detection area A. After that, there is a possibility of leaving the passage 105. Therefore, the entrance detection area flag of the record corresponding to the passerby radio tag 107 is cleared (step S466), and the tag location and update time are updated (step S467).

  As described above, the position of the passer-by wireless tag 107 existing in the predetermined area 101 is continuously detected at an arbitrary time interval, and the ID list for each passage is displayed based on the position information of the passer-by wireless tag 107. The record corresponding to the passer-by radio tag 107 is continuously updated. When the passer-by 106 finishes passing through the passage, that is, when the wireless tag is detected in the exit area, the record of the passer-by wireless tag 107 is deleted. Even when the passer-by wireless tag 107 is detected outside the detection area of the passage 105, the record of the passer-by wireless tag 107 is deleted if a predetermined time has elapsed.

  In addition to the processing described above, for example, when there is a record of the passer-by wireless tag 107 that is not detected even if a predetermined time is exceeded in the ID list, processing for deleting this record can also be performed. Further, when the number of records of the plurality of passer-by wireless tags 107 that are not processed in each ID list exceeds a predetermined number, a process of deleting these may be performed. By adding such processing, the accuracy of the ID list can be further increased.

  In the present embodiment, the passage 105 of the automatic ticket gate has been described as one-way. However, the direction in which the passer-by 106 enters the passage 105 is identified by the passer-by detector 150, and the detection areas A to C of the passage 105 described above. It is also possible to pass the passerby 106 alternately from both directions.
