A sequence diagram (procedure diagram or flowchart) for explaining the contents and an interrelation diagram are shown.

  The operation will be described with reference to FIG. FIG. 5 is expressed in a table format. In FIG. 5, as described on the upper side, in the horizontal direction from the left side to the right side, the column “Person (passer) position” 101 in the passage 11, the operation (processing) in the wireless IC tag 13-1. Column 102 indicating the operation of the entrance side identification information transmitting unit 61, a column 104 indicating the operation of the entrance side tag information receiving unit 62, a column 105 indicating the operation of the exit side identification information transmitting unit 63, and the exit The column 106 indicating the operation of the side tag information receiving unit 64 and the operation of the main body portion of the touchless gate device 21A, that is, the “main body control unit 54 / determination unit 66 / detection units 67, 68” of the processing / control system 57 ( A column 107 indicating (processing content) is shown. In each of the columns 102 to 107, processing procedures are shown along the vertical time axis in accordance with the transition of the position of the person in the passage 11 shown in the column 101. In the column 101, as areas (states) through which people (passers) inside and outside the passage 11 can pass, before entering the gate device, entrance area (entrance side detection area 41), inside the passage, exit area (exit side detection) Region 41) and five regions (states) after leaving the gate device are shown. Processing corresponding to the area through which the passing person passes in the passage 11 is performed. Hereinafter, processing contents will be described according to the area in the passage 11.

<Before entering gate device>
In this state, a user (person or passerby) approaches the entrance of the passage 11 in an attempt to pass through the passage 11 formed by the pair of touchless gate devices 21A and 21B. The person possesses the wireless IC tag 13-1. This state is the positional relationship among the touchless gate devices 21A and 21B, the passage 11, and the wireless IC tag 13-1 shown in FIG. A person who has the wireless IC tag 13-1 tries to pass through the passage 11 as it is without performing any special action. The wireless IC tag 13-1 has an area 31 as a communication area. The wireless IC tag 13-1 is waiting to receive identification information (step S101). That is, the wireless IC tag 13-1 is present outside the identification information receiving area 33 of the entrance side identification information transmitting unit 61 (the entrance side identification information transmitting unit 43 in FIG. 1). In this state, the wireless IC tag 13-1 is held in a state waiting for identification information reception.

<Inlet area>
When a person (passer-by) enters the entrance area, that is, the detection area 41 on the entrance side, the wireless IC tag 13-1 exists in the identification information reception area 33 of the entrance side identification information transmission unit 61. As a result, the wireless IC tag 13-1 performs identification information reception processing (step S102). In the reception of identification information (step S102), “identification information” is transmitted from the entrance-side identification information transmission unit 61 to the wireless IC tag 13-1, and the wireless IC tag 13-1 receives this. The wireless IC tag 13-1 writes that “identification information” has been received in the reception record in the memory of the tag control unit 71 (step S103).

  In the touchless gate device 21A, when a person enters the detection area 41, the detection unit 26, that is, in this case, the entrance side area detection unit 67 detects the person. In the processing / control system 57 in the touchless gate device 21A, when the entrance side area detection unit 67 detects a person (passer) (step S601), the detection information is sent to the entrance side identification information transmission unit 61. The detection information is also sent to the main body control unit 54 as shown in FIGS.

  Upon receiving the detection information, the entrance-side identification information transmission unit 61 generates predetermined “identification information” (step S201). The generated predetermined “identification information” is transmitted from the entrance-side identification information transmission unit 61 to the wireless IC tag 13-1 (step S202). The wireless IC tag 13-1 receives the “identification information” transmitted in this way. When receiving the detection information from the entrance side area detection unit 67, the entrance side identification information transmission unit 61 repeats the above steps S201 and S202.

  As illustrated in FIG. 4, the wireless IC tag 13-1 includes an identification information reception unit 71, a tag control unit 72, and an information transmission unit 73. The tag control unit 72 is constituted by a CPU, and creates predetermined “information” to be transmitted to the processing / control system 57 side of the touchless gate device 21A based on “identification information” given from the identification information receiving unit 71. Between the wireless IC tag 13-1 and the processing control system 57, “identification information” is transmitted from the entrance side identification information transmitting unit 61 to the identification information receiving unit 71 by the radio wave E1. The predetermined “information” output from the tag control unit 72 is transmitted from the information transmission unit 73 by the radio wave E2.

  The “identification information” generated in the entrance-side identification information transmission unit 61 and transmitted to the wireless IC tag 13-1 is a response or a response to the wireless IC tag 13-1. This is information for enabling the validity of the information to be verified, or information for successfully transmitting the response.

  In the information transmission in the prior art, as described above, only “location identification information” is identification information. In other words, only identification information related to “transmission location” or the like is transmitted.

  On the other hand, the “identification information” according to the present invention transmitted from the entrance-side identification information transmission unit 61 to the wireless IC tag 13-1 is “other information” other than “location identification information” together with “location identification information”. Is included. That is, other information is transmitted simultaneously with the “location identification information”. Examples of “other information” include “service identification information”, “RF channel”, “serial number”, “transmission timing”, and the like. The above “identification information” is created by appropriately combining these other information according to the conditions.

  When the “identification information” includes “service identification information”, the “service identification information” is placed at the beginning, followed by “location identification information” after “service identification information”.

  That is, the “identification information” is, for example, “service identification information + location identification information”, “service identification information + location identification information + RF channel”, “service identification information + location identification information + RF channel + serial number”, or “ Service identification information + location identification information + RF channel + serial number + transmission timing ”.

  In the above, “service identification information” is information indicating a format of information following the service identification information. According to this service identification information, different services can be handled. In other words, it is possible to receive different formats of location identification information. When there is no “service identification information”, information is transmitted in a single format. That is, if “location identification information” unified for various services is defined, “service identification information” can be omitted. In this case, “location identification information” is location identification information including service identification information, unlike conventional location identification information.

  When the “service identification information” is omitted, the “identification information” is, for example, “location identification information + RF channel”, “location identification information + RF channel + serial number”, or “location identification information + RF channel +”. "Serial number + transmission timing".

  “Location identification information” in this embodiment is literally information for location identification. The “location identification information” needs at least information that can be distinguished from information from the wireless IC tag that has passed through the passage of the surrounding gateless gate device. Usually, for example, “passage number + entrance / exit identification symbol”. Considering the validity of the passage history, for example, “station number + corner number + passage number + entrance / exit identification symbol”. In addition, considering that the wireless IC tag is shared with those other than the railway system, it is preferable to add service identification information.

  In the above, “sequence number” is a simple sequence number. This sequence number may represent a part of time, for example.

  “Transmission timing” is a transmission timing at which each wireless IC tag is randomly generated. The “transmission timing” is generated using, for example, transmission timing information and a tag ID as keys. The above “serial number” can also be used as a key for transmission timing. Furthermore, the maximum delay time can be used as part of the transmission timing and sent.

  As described above, in addition to “location identification information”, “identification information” transmitted from the entrance side identification information transmission unit 61 of the processing / control system 57 of the touchless gate device 21A to the wireless IC tag 13-1 One of “service identification information”, “RF channel”, “serial number”, “transmission timing”, or a combination thereof is included.

  In the “identification information”, a transmission channel, that is, an RF channel is further specified at each location based on the “location identification information”. As a result, when there are a plurality of wireless IC tags in the passage, a transmission route from the plurality of wireless IC tags to the fixed side, that is, the touchless gate device side can be secured, and reliable information transmission can be performed.

  Further, in order to enable normal open system operation, the passage 11 is provided with two locations as areas for transmission from the fixed side (touchless gate device 21A) to the wireless IC tag 13-1. In the configuration of the present embodiment shown in FIGS. 1 to 4, an entrance side identification information transmission unit 61 and an exit side identification information transmission unit 63 (identification information transmission units 43 and 44, identification information reception areas 33 and 34) are provided. ing. In one transmission region (entrance-side identification information transmission unit 61 or exit-side identification information transmission unit 63), that is, when viewed from the wireless IC tag side, a plurality of wireless IC tags are present in either of the identification information reception areas 33 and 34. If it exists, the “identification information” includes the “serial number” and “transmission timing” as described above so that the necessary wireless IC tag can be reliably transmitted. The “serial number” is combined with a symbol (wireless IC tag information: tag ID) inherently included in the wireless IC tag. As described above, “transmission timing” is created based on a certain rule of a combination of transmission timing information and a tag ID.

The “serial number” changes according to the wireless IC tag, and the transmission timing of each wireless IC tag changes accordingly. Therefore, the information of the wireless IC tag is not transmitted to the touchless gate device 21A or the like forever. It can be avoided.
The wireless tag IC 13-1 that has completed a certain transmission process with the touchless gate device 21 </ b> A suspends communication for a certain period of time, thereby suspending all other wireless IC tags that may exist in the passage 11. The probability that communication can be performed can be increased.

  Returning to FIG. 5, in the entrance area, the wireless IC tag 13-1 generates “identification information + tag information” after reception recording and writing (step S 103), and transmits it from the information transmission unit 73 by the radio wave E 2. (Step S104). “Tag information” is a tag ID or the like that identifies the wireless IC tag 13-1. Thereafter, the wireless IC tag 13-1 writes that “identification information + tag information” has been transmitted to the transmission record in the memory of the tag control unit 71 (step S105). Further thereafter, the wireless IC tag 13-1 is in a state of waiting for reception of the identification information inside the entrance area and the passage 11.

  In the above, more specifically, the “tag information” is added to the unique tag ID of the wireless IC tag 13-1 as to when / where the response is the “identification information” transmitted. It is also possible to add “tag status information”. Here, the “tag status information” is, for example, information on a failure of the wireless IC tag 13-1 or its remaining battery level.

When the wireless IC tag 13-1 transmits “identification information + tag information” from the information transmitting unit 73, the wireless IC tag 13-1 receives the tag information receiving unit 62 of the processing / control system 57 (step S301). The entrance-side tag information receiving unit 62 confirms the identification information from the received “identification information + tag information” (step S302), and notifies the determination unit 66 of the tag information. The determination unit 66 receives the tag information (step S602), and determines the content of the received “tag information” (step S603). The determination unit 66 determines the processing contents for the passage permission / non-permission and the record information corresponding to the tag information from the received tag information. Since the determination unit 66 knows the identification information to be received by the entrance-side tag information reception unit 62, the information other than information including the identification information is processed as invalid. Information determined by the determination unit 66 is sent to the main body control unit 54. The main body control unit 54 performs display / door control via the door driving unit 53 and / or the display driving unit 56 based on the information content (step S604). Also, processing is performed on the record information corresponding to the tag information. The door 52 and the display unit 55 perform necessary opening / closing operations or display operations. Thereafter, exit detection of the entrance area is performed (step S60 5 ), and further, it is registered that there is a person (passer) possessing the wireless IC tag 13-1 in the passage 11 (step S606).

<Exit area>
When a person moving in the passage 11 enters the exit area, that is, the exit-side detection area 41, the wireless IC tag 13-1 exists in the identification information reception area 33 of the exit-side identification information transmission unit 63. . As a result, the wireless IC tag 13-1 performs identification information reception processing (step S107). In the identification information reception (step S107), the “identification information” is transmitted from the exit side identification information transmission unit 63 to the wireless IC tag 13-1 by the radio wave E3, and the wireless IC tag 13-1 receives this. In the wireless IC tag 13-1, the fact that the “identification information” has been received is written in the reception record in the memory of the tag control unit 71 (step S108).

  In the touchless gate device 21A, when a person enters the exit-side detection area 41, the detection unit 26, that is, in this case, the exit-side area detection unit 68 detects the person. In the processing / control system 57 in the touchless gate device 21A, when the exit side area detection unit 68 detects a person (passer) (step S607), the detection information is sent to the exit side identification information transmission unit 63. The detection information is also sent to the main body control unit 54 as shown in FIGS.

  Thereafter, in the exit area, the exit area identification information transmission unit 63 executes generation of identification information (step S401) and transmission or transmission of identification information (step S402). In the wireless IC tag 13-1, “identification information + tag information” transmission (step S109), transmission record writing (step S110), and reception of identification information (step S111) are sequentially executed. Each of these steps S401 and S402 has the same processing contents as the aforementioned steps S201 and S202, and each of steps S109, S110 and S111 has the same processing contents as those of the aforementioned steps S104, S105 and S106. Transmission in step S109 is performed by the radio wave E4.

  Regarding the movement in the exit area, when “identification information + tag information” is transmitted by the wireless IC tag 13-1, the exit-side tag information receiving unit 64 receives “identification information + tag information” correspondingly ( Step S501), confirmation of identification information (step S502), and notification of tag information (step S503) are executed. Each of these steps S501, S502, and S503 has the same processing contents as the above-described steps S301, S302, and S303. When the tag information is notified based on step S503, the main body portion sequentially receives the tag information (step S608), determines (step S609), controls the display / door (step S610), and detects area exit ( Each process of step S611) and elimination of presence in the passage (step S612) is executed. Each of steps S608, S609, S610, and S611 has the same processing content as steps S602, 603, 604, and 605 described above. In step S612, it is detected that a person has left the exit area, and the record that the person has previously registered as not existing in the passage 11 (step S606) is deleted from the memory.

  As described above, the wireless IC tag 13-1 and the touchless gate device possessed by the person until the person (passer) enters the passage 11 formed by the touchless gate devices 21A and 21B. Information transmission / reception processing is performed with the processing / control system 57 of 21A. When the predetermined transmission is completed, the communication for a certain period can be suspended. That is, a pause time can be set for a wireless IC tag whose transmission has been confirmed. Since communication (information transmission / reception) can be performed with other wireless IC tags that have entered the passage 11 at the time of the suspension, as a result, the probability that communication with all other wireless IC tags related to the passage 11 can be achieved. Can be increased.

  In addition, regarding the pause time, since the pause time is changed according to the maximum number of wireless IC tags existing in the detection area 41 (entrance side and exit side) of the target passage 11, the certain time period related to the pause is set to “ It can also be sent in addition to “identification information”. In other words, the suspension time is set according to the density of users who use the passage 11.

  In the above, the transmission or transmission of the “identification information” from the entrance side identification information transmission unit 61 or the exit side identification information transmission unit 63 may be performed at a constant cycle, or something (human detection) is detected in the detection area 41. Etc.) may be performed when it is detected.

  A block 81 indicated by a broken line in FIG. 3 or the like is an in-passage area detection unit corresponding to a detection area set at a substantially central portion of the passage 11. An in-passage area detection unit 81 may be added to the above-described entrance side area detection unit 67 and the exit side area detection unit 68. When the in-passage area detection unit 81 is provided, the same hardware configuration and software configuration as the entrance side area detection unit 67 or the exit side area detection unit 68 are added.

  In the above description, an example of information transmission / reception with the wireless IC tag 13-1 in the passage 11 made by the touchless gate devices 21A and 21B has been described. However, wireless communication in the passage 12 made by the touchless gate devices 22A and 22B is described. A method of transmitting and receiving information between the IC tag 13-2 and the processing / control system is configured in the same manner.

  Next, with reference to FIG. 6, the detailed operation procedure of each part regarding the information transmission / reception of entrance / exit management performed between the wireless IC tag 13-1 and the touchless gate device 21A will be described.

  In this description, an example of an operation procedure in information transmission / reception between the entrance-side identification information transmission unit 61 (identification information transmission unit 43) and the wireless IC tag 13-1 in the touchless gate device 21A described above will be described. However, the entrance-side identification information transmission unit 61 is generally referred to as the identification information transmission unit 43, the entrance-side tag information reception unit 62 is referred to as the “touchless gate device reception unit 91”, and the aforementioned “main body portion” (FIG. 5). Will be described as “the main body of the touchless gate device 21A”. Accordingly, the operation contents of the “identification information transmission unit 43”, “wireless IC tag 13-1”, “touchless gate device reception unit 91”, and main body of the touchless gate device 21A will be described in more detail.

  In FIG. 6, when the power switch of the main body of the touchless gate device 21A is turned on (step S621), it is determined whether the power switch is on or off (step S622). (Step S623). While the state of the power switch is ON, step S623 of the startup process is continued. When the power switch is turned off, an end process is executed (step S624).

  When step S623 of the activation process is performed in the touchless gate device 21A, a command (RE1) of “identification information setting” based on this is issued, and identification information setting is performed by the identification information transmission unit 43 (step S221). A “Receive Channel Setting” command (RE2) is issued, and a state of waiting for reception is set by the touchless gate device receiver 91 (step S321), and a state of waiting for information reception is set by the main body of the touchless gate device 21A. (Step S631).

  When identification information setting is performed in the identification information transmission unit 43 (step S221), an object detection wait state is set (step S222). At the next time point, it is determined whether or not an object is detected in the detection area (detection area 41 shown in FIG. 1) (steps S223 and S224). When the object detection is NO, steps S222 to S224 are repeated, and when the object detection is YES, the process proceeds to the next step S225. In step S225, information is transmitted from the identification information transmitter 43 to the wireless IC tag 13-1. The transmitted information is “identification information” set in step S221. As described above, the “identification information” in this embodiment includes “location identification information” and other information such as “service identification information”, “RF channel”, “serial number”, “transmission timing” as appropriate. It is. In FIG. 6, reference numeral 92 indicates an example of the transmitted “identification information”. In this example, “service ID (corresponding to service identification information)”, “device ID (corresponding to location identification information)”, “reception channel (corresponding to RF channel)”, “device state (corresponding to serial number)”, “Additional information” is shown. After the information transmission step S225, the serial number count is incremented by one (step S226). Further, after that, a pause for a predetermined time is performed (step S227), and the process returns to step S222. The pause for a predetermined time is for setting the apparatus state so that information can be transmitted to other wireless IC tags after the information transmission to the wireless IC tags 13-1 is completed.

  The wireless IC tag 13-1 is in a state waiting for identification information reception in the initial state (step S121). In this state, when receiving an information transmission from the identification information transmission unit 43, normal reception is performed (step S122), and reception is recorded (step S123). Thereafter, it is determined whether or not the transmission condition is satisfied (steps S124 and S125). If NO, the process returns to step S121, and if YES, the process proceeds to step S126. In step S126, tag information is further added at the transmitted channel and timing, and transmission is performed to the touchless gate device receiving unit 91. Thereafter, transmission recording is performed (step S127), and the process returns to the initial step S121. Reference numeral 93 describes a storage area related to the reception record in step S123 and the transmission record in step S127. These reception record and transmission record are stored in a storage area (memory) in the wireless IC tag 13-1. Saved.

  When receiving the information transmission from the wireless IC tag 13-1, the touchless gate device receiving unit 91 in the state of waiting for reception (step S321) determines whether or not the information is normally received (steps S322 and S323). When it is normal (YES), the received information (tag information) is notified to the main body of the touchless gate device 21A, and the process returns to step S321 again. If it is not normal (NO), the process immediately returns to step S321.

  Next, in the main body of the touchless gate device 21A in the state of waiting for information reception (step S631), when there is a notification of information (tag information) from the touchless gate device reception unit 91, the information is received (step S632). ). Thereafter, the content of the received tag information is determined (step S633), and display and door control are performed according to the content of the tag information (step S634). After step S634, the state of the main body of the touchless gate device 21A returns to step S631, and is held in a state waiting for information reception.

  In the above, regarding the reception record and transmission record stored (stored) in the storage area (memory) of the wireless IC tag 13-1, the wireless IC tag 13-1 receives information from the external device via the identification information receiving unit 71. When receiving a read command, the information transmission unit 73 is configured to transmit the contents of the reception record and the content of the transmission record stored in the storage area to the external device.

  FIG. 7 shows a configuration of a transmission / reception record reading device as an example of the external device.

When the operator operates the operation unit 212 to input a transmission / reception record request instruction signal, the instruction signal is transmitted to the transmission / reception record request transmission unit 214 via the reading device control unit 211. The transmission / reception record request transmission unit 214 transmits a command signal 216 related to the transmission / reception recording request to the wireless IC tag 13-1 based on the signal transmitted from the reading device control unit 211. When the wireless IC tag 13-1 receives a command signal 216 related to the transmission / reception recording request, the wireless IC tag 13-1 prepares transmission / reception recording data from the storage area according to the command signal 216, and the information transmission unit 73 reads out the transmission / reception record as a recording transmission signal 217. The data is transmitted to the transmission / reception record reception unit 215 of the apparatus 201. Data related to the transmission / reception record received by the transmission / reception record reception unit 215 is displayed on the display unit 213 via the reading device control unit 211. In this manner, the transmission / reception record data stored in the storage area of the wireless IC tag 13-1 is read by the transmission / reception record reading device 201 which is an external device.
