Description

  The present invention relates to a technique for managing passage of a passage based on information from a portable device carried by a passerby.

  Conventionally, in a traffic management system that manages entrance / exit to / from facilities such as stations, amusement parks, and event venues, the traffic of passers-by may be managed using proximity wireless communication between a gate device and a portable device. Specifically, when the passerby holds the portable device over an antenna provided at the entrance of the gate device, the gate device reads predetermined information from the portable device. Based on the read information, the gate device performs predetermined traffic management such as opening / closing the door and recording entry / exit.

  In the traffic management system using the proximity wireless communication described above, it is necessary for the passerby to take time to hold the portable device over the antenna. Therefore, a traffic management system using short-range wireless communication having a wide communication band that overlaps a passage has been proposed in order to save the time for a passer-by to hold the portable device (see, for example, Patent Document 1).

  The traffic management system disclosed in Patent Document 1 uses a portable device capable of short-range wireless communication and a center device connected to a portable network. The portable device notifies the center device of identification information of the portable device via the portable network before the passerby enters the passage. The center device determines whether or not traffic is permitted based on the acquired entry notification information, and notifies the gate device of identification information of the portable device permitted to pass. The gate device acquires the identification information of the portable device through short-range wireless communication, and performs predetermined traffic management depending on whether the acquired identification information is permitted to pass by the center device.

Japanese Patent Laid-Open No. 2003-196686

  In general, the communication area of short-range wireless communication varies greatly due to the influence of the human body and peripheral devices. For this reason, if the communication area of short-range wireless communication is set in units of several tens of centimeters, radio waves may be weakened by the influence of the human body and peripheral devices, and communication between the portable device and the gate device may become impossible. It was. Therefore, in a traffic management system using short-range wireless communication, it is necessary to ensure the radio field strength of short-range wireless communication to a certain degree or more in order to reliably perform communication between the portable device and the gate device.

  However, if the radio field intensity of the short-range wireless communication is secured to a certain level or more, conversely, it becomes difficult to limit the communication area of the antenna to only the target path. For this reason, for example, when a plurality of gate devices are arranged adjacent to each other, the communication area of the antenna reaches the adjacent passage, and the portable device in the adjacent passage passes through the target passage. There was a risk of incorrect traffic management as belonging to those who pass.

  As described above, in the conventional traffic management system, when a passer-by passes through the passage without holding the portable device over the antenna, the gate device grasps that the passer-by who has entered the passage carries the mobile device. I couldn't.

  Accordingly, an object of the present invention is to understand that even if a passer-by passes the passage without holding the mobile device over the antenna, the gate device grasps that the passer-by who has entered the passage carries the mobile device and performs an appropriate process. It is to provide a technology that makes it possible to perform.

  The traffic management system according to the present invention includes the following portable device and gate device. The portable device according to the present invention is carried by a passerby of a managed passage. The gate device according to the present invention is provided in a path to be managed.

  In addition, the gate device intermittently emits a reference signal with a constant amount of transmission energy from each of the first antenna and the second antenna arranged at different positions in the passage direction of the passage. Whether the portable device has entered a predetermined entry position in the passage direction of the passage based on the received energy amounts of the two reference signals received from the first antenna and the second antenna. When it is determined that the passer has entered the approach position, the gate device is notified of the entry notification information. The gate device executes a process for a passerby who has entered the approach position based on the entry notification information acquired from the portable device.

  The amount of received energy of the reference signal detected by the portable device changes according to the distance from the antenna. Therefore, in the above configuration, the two antennas are arranged at different positions in the traveling direction. Thereby, in a portable apparatus, it becomes possible to grasp | ascertain the position of the own apparatus in a channel | path direction from the distance to each of two antennas. Further, the mobile device notifies the gate device of the entry notification information at the timing of entering a predetermined entry position that is grasped from the received energy amounts of the two reference signals. Thereby, in a gate apparatus, it can grasp | ascertain whether the passerby who approached the approach position carries a portable apparatus, and can perform an appropriate process with respect to a passerby.

  Further, in the portable device, when the received energy amounts of the two reference signals received from the first antenna and the second antenna both exceed the threshold value, it may be determined that the passer-by has entered the entry position.

  Thereby, the approach to the approach position of a passerby can be grasped by simple processing.

  Further, in the portable device, a passer-by can enter the entrance position using a reference signal of each antenna emitted from the first antenna and the second antenna provided on both sides of the passage with a high received energy amount. It is preferable to determine whether or not the situation has entered.

  As a result, even if the passerby is carrying the portable device on the left or right side with respect to the direction of travel, even if the reference signal from one of the antennas is greatly attenuated or detoured due to the influence of the human body, the other side The reference signal from the antenna reaches the portable device without being affected by such an effect. Therefore, the position of the own device in the direction of the passage can be grasped more reliably by the portable device.

  The mobile device further includes a registration device in which the identification information of the portable device is registered. The portable device notifies the entry notification information including the identification information of the portable device to the gate device, and the identification information included in the entry notification information in the gate device. It is preferable to determine whether to permit or prohibit passage of the passage based on whether or not is registered in the registration device, and to perform processing for passers-by based on this determination. Thereby, in the gate device, it is possible to determine whether passage of the passage is permitted or prohibited only by confirming the identification information, and it is possible to reduce processing time required for determining whether or not passage is possible.

  In addition, as the gate device, when the entry notification information is acquired, the entrance side gate device that links the identification information of the portable device and issues the entry information, and when the entry notification information is acquired, the identification information of the portable device is linked. An entry gate device that issues information, and may further include a fee settlement device that acquires entry information and entry information and settles the fee for each identification information of the portable device. This realizes traffic management by the so-called post-pay method in which the mobile device and the gate device perform wireless communication to settle the fee just by passing the passage without passing the mobile device over the antenna. Can do. For this reason, various facilities for prepaid processing are not required for the entire system, and system labor can be saved.

  According to the present invention, even when a passer-by passes the passage without holding the portable device over the antenna, the gate device grasps that the passer-by who has entered the passage carries the mobile device and performs appropriate processing. be able to.

It is a schematic diagram which shows the example of distance discrimination | determination according to the position of a portable terminal, and arrangement | positioning of an antenna.

  First, a schematic configuration of the traffic management system according to the present invention will be described.

  FIG. 1 is a schematic diagram showing a traffic management system 1 according to the first embodiment of the present invention.

  The traffic management system 1 includes a portable device 11 and a gate device 12. The portable device 11 is carried by a passerby 13 who wants to pass through the passage 14 to be managed. The gate device 12 is provided in the vicinity of the passage 14 to be managed, and manages the passage of the passerby 13. The portable device 11 notifies the gate device 12 of the entry notification information when it is determined that the predetermined position (the entry position 15) in the vicinity of the passage 14 is reached along with the passage of the passerby 13 in the passage 14. Here, the entry notification information includes information used for determining whether or not a passer can pass. The gate device 12 determines whether or not the passer-by 13 can pass based on the entry notification information notified from the portable device 11, and performs opening / closing control of the door 18 provided in the passage 14 based on the determination result of whether or not the pass is possible. .

  Whether the mobile device 11 has reached the entry position 15 is determined based on a reference signal emitted from the antennas 16 and 17 provided in the passage 14. The antennas 16 and 17 are provided in the vicinity of the passage 14 and are disposed at different positions in the traveling direction of the passerby 13 in the passage 14. Each of the antennas 16 and 17 has a communication area 20 that spreads at least in the horizontal direction and overlaps with each other in the passage 14.

  FIG. 2A is a time waveform diagram in which the transmission energy amounts of the reference signals emitted from the antennas 16 and 17 are superimposed. The reference signal emitted from the antennas 16 and 17 to the communication area 20 is a pulse wave signal having a constant transmission energy amount and a constant period, and is emitted in a time-division manner with a constant time interval. Note that the reference signal may be modulated by an appropriate modulation method other than amplitude modulation so as to have information of about several bits to several tens of bits.

  FIG. 2B is a diagram showing a change according to the distance of the energy amount of the reference signal in the communication area 20. The amount of energy of the reference signal emitted from the antennas 16 and 17 is attenuated so as to be inversely proportional to the square of the distance from the antennas 16 and 17.

  1, the received energy amount E1 that can be received by the portable device 11 of the reference signal emitted from the antenna 16 and the portable device 11 of the reference signal emitted from the antenna 17 can be received. The amount of received energy E2 is shown. The received energy amounts E1 and E2 vary depending on the position in the direction along the path 14. The received energy amounts E1 and E2 are larger at positions closer to the antennas 16 and 17 that have emitted the respective reference signals, and are smaller at positions farther from the antennas 16 and 17. Therefore, when the communication areas 20 of the antennas 16 and 17 are overlapped with each other, the amount of received energy E1 and E2 increases as the passerby 13 enters the passage 14.

  Therefore, in the present embodiment, a threshold is set for the received energy amounts E1 and E2, and the mobile device 11 grasps the position where both the received energy amounts E1 and E2 exceed the threshold as the entry position 15.

  FIG. 3A is a block diagram of the mobile device 11. The portable device 11 includes a control unit 21 and a short-range wireless communication unit 22. The control unit 21 is a functional block as a whole of functions such as a CPU, a ROM, and a RAM. The short-range wireless communication unit 22 is a communication unit that performs short-range wireless communication. In addition, the portable device 11 may further include a configuration such as a display unit, a touch panel, or a mobile phone communication unit.

  In the control unit 21, the entry notification program of the present invention is installed, and the process of the entry notification program is executed by the memory and the CPU. Thereby, the approach notification program of the present invention causes the control unit 21 to function as the portable side processing unit 23 and causes the short-range wireless communication unit 22 to function as the information transmission / reception unit 24 and the reference signal detection unit 25.

  FIG. 3B is a block diagram of the gate device 12. The gate device 12 includes a control unit 31, a short-range wireless communication unit 32, and a door control unit 33. The control unit 31 is a functional block as an overall function of the CPU, ROM, RAM, and the like. The near field communication unit 32 is a communication unit that performs near field communication. The door control unit 33 controls the door 18 (see FIG. 1) provided in the passage 14 (see FIG. 1) of the gate device 12 to open and close. In addition, the gate device 12 may further include, for example, a configuration such as a dedicated line communication unit for communication with the host device and a sensor that detects a passerby.

  The traffic management program of the present invention is installed in the control unit 31, and the process of the traffic management program is executed by the memory and the CPU. As a result, the traffic management program of the present invention causes the short-range wireless communication unit 32 to function as the information transmission / reception unit 35 and the reference signal emission unit 36 with the control unit 31 functioning as the passage-side processing unit 34.

  FIG. 4A is a diagram illustrating a schematic processing flow of each unit in the gate device 12. FIG. 4B is a diagram illustrating a schematic processing flow of each unit in the mobile device 11.

  The reference signal emitting means 36 of the gate device 12 emits the reference signal intermittently at a constant transmission energy amount to the communication area 20 via the antenna 16 (S11). Further, the reference signal emitting means 36 emits the reference signal intermittently at a constant transmission energy amount to the communication area 20 via the antenna 17 (S12). These steps S11 and S12 correspond to the releasing step in the present invention.

  The reference signal detection means 25 of the portable device 11 receives the reference signal emitted from the antenna 16, detects the received energy amount E1 of the reference signal, and stores it in the memory (S13). Further, the reference signal detecting means 25 receives the reference signal emitted from the antenna 17, detects the received energy amount E2 of the reference signal, and stores it in the memory (S14).

  And the portable side processing means 23 of the portable apparatus 11 compares the received energy amounts E1 and E2 stored in the memory with the threshold values (S15, S16), so that the own apparatus reaches the predetermined entry position 15 in the passage 14. (S15, S16: YES). These steps S15 and S16 correspond to the entry determination step in the present invention.

  And the portable side processing means 23 of the portable device 11 enters when the received energy amounts E1 and E2 both exceed the threshold value, that is, when the own device has reached the predetermined entry position 15 in the passage 14. The notification information is issued, and the entry notification information is notified to the gate device 12 through the information transmission / reception means 24 (S17). This step S17 corresponds to the notification step in the present invention.

  Thereby, the passage side processing means 34 of the gate device 12 acquires the entry notification information from the portable device 11 via the information transmission / reception means 35 at the timing when the portable device 11 reaches the entry position 15 (S18: YES). When the passage-side processing unit 34 acquires the entry notification information, the passage-side processing unit 34 determines whether or not the passerby who carries the portable device 11 is allowed to pass based on the acquired entry notification information (S19), and the door 18 through the door control unit 33. Open / close control. Specifically, when it is determined that passage is permitted, the passage-side processing unit 34 controls the opening of the door 18 via the door control unit 33, and when it is determined that passage is prohibited, the door-side processing unit 34 opens the door via the door control unit 33. 18 is closed. This step S19 corresponds to the traffic management step referred to in the present invention.

  Therefore, in this traffic management system 1, the passer-by 13 only passes the passage 14 while carrying the portable device 11, and the passer-by is at the entry position 15 in the passage 14 without holding the portable device 11 over the antenna 16. The entry notification signal can be notified to the gate device 12 at the time of entering, and the gate device 12 can perform processing for the passerby 13 at an appropriate timing.

  As described above, the traffic management system, gate device, portable device, approach notification program, traffic management program, and traffic management method of the present invention can be implemented. Here, the case where only the notification of the entry notification information is performed from the portable device to the gate device is shown as an example of the portable side processing, but the portable side processing may also perform other processing. For example, the mobile-side processing stores information included in the reference signal, for example, antenna identification information or passage device identification information, or notifies other devices via a mobile phone line. You can also. In addition, here, as the passage-side processing, the case where the gate device determines whether or not to allow passage and the door opening / closing control is illustrated as an example, but the passage-side processing may be other processing. For example, in the passage-side process, for example, identification information of the portable device can be recorded in the gate device, or the information can be notified to other devices via a dedicated line of the gate device.

  Next, a case where a station management system is constructed as a traffic management system will be described. FIG. 5 is a block diagram of the station service management system 101 according to the second embodiment of the present invention.

  The station service management system 101 includes a mobile terminal 111, an automatic ticket gate 112, an automatic ticket gate 113, a mobile registration device 104, a station service management host device 105, and a checkout device 106. The portable terminal 111 is carried by a passenger who has registered for use of the system in advance. The automatic ticket gate 112 is provided in the entrance station facility 102 for passengers. The automatic ticket gate 113 is provided at a station facility 103 where passengers participate. The mobile registration device 104 is provided in each station facility or station management superordinate facility. The station service management host device 105 is provided in the station service management host facility. The settlement apparatus 106 is provided in an external facility that manages bank accounts and the like. Here, the station service management system 101 corresponds to the traffic management system referred to in the present invention. The portable terminal 111 corresponds to the portable device referred to in the present invention. The automatic ticket gates 112 and 113 correspond to the gate device referred to in the present invention. The station management high-order apparatus 105 and the settlement apparatus 106 constitute a fee settlement apparatus referred to in the present invention. The station service management host device 105 and the portable registration device 104 correspond to the registration device referred to in the present invention.

  The portable terminal 111 holds terminal identification information unique to the own device. The terminal identification information is issued when the mobile terminal 111 is manufactured or when the mobile terminal 111 is registered for use in the system. The mobile registration device 104 holds, as registration information, terminal identification information of the mobile terminal 111 that is permitted to pass by the automatic ticket gate 112 and the automatic ticket gate 113. The registration information is registered from the mobile terminal 111 or the station administration management upper device 105 when the mobile terminal 111 is registered for use of the system.

  Note that a security authentication code may be attached to the terminal identification information and the registration information. In this case, when the portable terminal 111 is permitted to pass by the automatic ticket gate 112 and the automatic ticket gate 113, the security authentication code is transmitted and received, and the portable terminal 111 corresponds to the authentic terminal identification information registered. It is better to determine whether or not to do. Further, the registration information may be information in which predetermined condition information such as available station facilities and periods is linked. In this case, the registration of the terminal identification information may be canceled using the condition information, or the station facilities that are permitted to pass may be restricted.

  The automatic ticket gate 112 manages the passage of passengers (passers) who want to enter the entrance station facility 102, and corresponds to the entrance-side gate device in the present invention. The automatic ticket gate 113 manages the passage of passengers (passers) who want to enter from the entry station facility 103, and corresponds to the entry side gate device referred to in the present invention.

  The automatic ticket gates 112 and 113 are configured to repeatedly emit a reference signal similar to that of the first embodiment by short-range wireless communication. However, in the present embodiment, the automatic ticket gates 112 and 113 are configured to emit reference signals from more antennas than in the first embodiment. The detailed configuration of the automatic ticket gates 112 and 113 will be described later.

  The portable terminal 111 is configured to detect the received energy amount similar to that of the first embodiment by short-range wireless communication. And the portable terminal 111 grasps | ascertains whether an own apparatus has entered into the automatic ticket gates 112 and 113 based on the received energy amount. When it is determined that the mobile device 111 has entered the automatic ticket gates 112 and 113, the portable terminal 111 notifies the automatic ticket gates 112 and 113 of the entry notification information through short-range wireless communication. Here, the entry notification information includes the terminal identification information of the mobile terminal 111. Note that the entry notification information includes other various information, for example, information on the detected received energy amount (obtained entry position), terminal state information such as the battery state of the mobile terminal 111, and the previous pass through the automatic ticket gate Past information such as the time of day and station, usage information such as the time when entering the automatic ticket gate this time, and the like may be included. Further, it is preferable that the entry notification information is encrypted by the encryption key method and transmitted from the portable terminal 111, and is decrypted and used on the automatic ticket gates 112 and 113 side.

  When the automatic ticket checkers 112 and 113 acquire the entry notification information notified by the portable terminal 111 through short-range wireless communication, whether or not the terminal identification information included in the entry notification information matches the terminal identification information included in the registration information. Determine whether. The registration information is acquired from the mobile registration device 104 immediately after the automatic ticket gates 112 and 113 acquire the entry notification information or in advance. The automatic ticket gates 112 and 113 permit the passerby who carries the portable terminal 111 when the terminal identification information matches between the entry notification information and the registration information, and the terminal identification information between the entry notification information and the registration information is When they do not match, the passerby carrying the mobile terminal 111 is prohibited. And the automatic ticket gates 112 and 113 control opening and closing of the door provided in the passage.

  In the determination of whether or not the automatic ticket gates 112 and 113 are allowed to pass, whether or not the pass is allowed may be determined using not only the terminal identification information but also other information included in the entry notification information. For example, if there is a possibility that the mobile terminal 111 becomes unusable while the passenger is moving based on the battery status of the mobile terminal 111, the passenger is prohibited from passing, and a separate pass ticket is prepared. Encourage passers-by to Further, based on the time information, passage outside business hours may be prohibited, or it may be detected that there is an abnormality in the entry / exit time.

  In addition, after determining that the passage is permitted, the automatic ticket gate 112 issues entrance information and notifies the station administration management higher level device 105 of the entrance information. The automatic ticket gate 113 issues entry information after notifying that the passage is permitted, and notifies the station administration management higher level device 105 of the participation information. The entrance information and the entry information include terminal identification information of the portable terminal 111, station facility identification information, time information, and the like.

  When the station administration management upper-level device 105 acquires the entrance information and the entry information from the automatic ticket gates 112 and 113, the station administration management upper device 105 detects that the terminal identification information included in the entrance information and the entry information coincides with each other. The fare (fee) is calculated from the combination of the station facility identification information included in the participation information. Then, the station service management upper-level device 105 identifies the user account based on the terminal identification information, and notifies the fare adjustment information for requesting the fare adjustment from the corresponding user account to the fare adjustment device 106, so-called post-pay method. Check out the fare.

  In the station management system 101 having such a schematic configuration, when the passer-by passes through the passage of the automatic ticket gates 112 and 113, the passage passes without passing the portable terminal 111 over the automatic ticket gates 112 and 113. be able to. At that time, various processes for managing the pass of the passer-by at an appropriate timing according to the entry notification information notified by the mobile terminal 111 through short-range wireless communication between the automatic ticket gates 112 and 113 and the mobile terminal 111 are performed. It can be carried out.

  Hereinafter, a more detailed configuration of the automatic ticket gates 112 and 113 and a more specific approach position determination mechanism in the portable terminal 111 will be described.

  FIG. 6 is a schematic diagram showing a situation where a passenger who intends to enter the entrance station facility 102 tries to enter the automatic ticket gate 112.

  A passenger (passerby 114) who intends to enter the entrance station facility 102 carries the portable terminal 111. The automatic ticket gate 112 manages the passage 115. The passage 115 has an entrance 116 and an exit 117 when viewed from the passer-by 114. On both sides of the passage 115, an automatic ticket gate 112 and an automatic ticket gate 112 'are provided. The automatic ticket gate 112 and the automatic ticket gate 112 'have the same configuration. The automatic ticket gate 112 ′ manages another passage adjacent to the passage 115.

  The automatic ticket gate 112 is provided with antennas 121 and 122. Further, the automatic ticket gate 112 'is provided with antennas 121' and 122 '. The antennas 121 ′ and 122 ′ are set or connected to the automatic ticket gate 112 so as to operate in synchronization with the antennas 121 and 122.

  The antenna 121 is disposed on the entrance 116 side of the top surface of the automatic ticket gate 112. The antenna 122 is disposed on the exit 117 side of the top surface of the automatic ticket gate 112. The antenna 121 'is disposed on the entrance 116 side of the top surface of the automatic ticket gate 112'. The antenna 122 'is disposed on the exit 117 side of the top surface of the automatic ticket gate 112'. That is, the antennas 121 and 122 and the antennas 121 ′ and 122 ′ are disposed on both sides of the passage 115. The antennas 121 and 122 are arranged at different positions in the passage direction of the passage 115. Similarly, the antennas 121 ′ and 122 ′ are arranged at different positions in the passage direction of the passage 115.

  The antennas 121, 122, 121 ′, 122 ′ are antennas that emit a reference signal by short-range wireless communication, and each have a communication area 120 that spreads at least in the horizontal direction and overlaps with the passage 14. The antennas 121, 122, 121 ′, 122 ′ emit reference signals to the respective communication areas 120.

  FIG. 7A is a time waveform diagram in which the transmission energy amounts of the reference signals emitted from the antennas 121, 122, 121 ', and 122' are superimposed. The reference signals emitted by the antennas 121, 122, 121 ', and 122' have the same fixed transmission energy amount. The reference signals emitted by the antennas 121, 122, 121 ', 122' have the same constant repetition period, and are emitted in a time-division manner at regular time intervals.

  As shown in FIG. 6, when a passer-by 114 carrying the mobile terminal 111 in a bag or pocket tries to enter the passage 115, the mobile terminal 111 emits from each of the antennas 121, 122, 121 ′, 122 ′. The received reference signal is received.

FIG. 7B is a diagram illustrating the received energy amount of the reference signal detected by the mobile terminal 111 according to the distance between each of the antennas 121, 122, 121 ′, 122 ′ and the mobile terminal 111. The amount of received energy detected by the mobile terminal 111 decreases as the distance from the antennas 121, 122, 121 ′, 122 ′ increases, and increases as the distance approaches. In the present embodiment, the received energy is received by the mobile terminal 111. By comparing the amount with the first threshold value and the second threshold value, a distance discrimination process for classifying the received energy amount into about three levels is performed. By this distance determination, the mobile terminal 111 determines whether the distance from the antenna that has emitted the reference signal to its own apparatus is, for example, one of three classifications: proximity determination, short-distance determination, and long-distance determination. The proximity determination is, for example, a distance of 0.1 to 0.5 meters. The short distance determination is, for example, a case where the distance is 0.5 to 1.4 meters. The long distance determination is, for example, a distance of 1.4 to 3.0 meters.

  The mobile terminal 111 performs the above-described distance determination every time it receives a reference signal that is time-divided from each of the antennas 121, 122, 121 ′, and 122 ′, and each antenna 121 of the mobile terminal 111 at that time. , 122, 121 ′, 122 ′. Then, when the grasped combinations of distances become predetermined ones, it is determined that the own device has reached the entry position 118 shown in FIG. 6, and the entry notice information is notified to the automatic ticket gate 112.

  FIG. 8 is a schematic view illustrating distance determination results for the antennas 121, 122, 121 ′, 122 ′ when the mobile terminal 111 passes through the passage 115 in a state where the mobile terminal 111 is exposed to the passage 115. Here, it is assumed that the areas A1 to A9 are arranged in order from the front to the rear in the traveling direction of the passage 115. The table in FIG. 8 shows the results of distance discrimination in a legend. The situation where two legends are arranged side by side in the area A5 indicates a situation in which the distance determination changes between the short distance determination and the long distance determination due to the influence of the human body or the surrounding environment.

  As shown in FIG. 8, in this case, the determination results of the antenna 121 and the antenna 121 'facing left and right are the same. The same applies to the antenna 122 and the antenna 122 '. Then, the distance discrimination results are different between the antenna 121 and the antenna 122 arranged along the passage 115, and between the antenna 121 'and the antenna 122'.

  In the legend shown in FIG. 8, in the areas A1 to A3 outside the front antenna 121, the rear antenna 122 becomes a long distance determination, and in the areas A7 to A9 away from the rear antenna 122, the front antenna 121 is determined. Is a long distance judgment. In areas A4 to A6 sandwiched between the front and rear antennas 121 and 122, both the antenna 121 and the antenna 122 are in proximity determination or short distance determination. For this reason, in this case, the result of the distance determination in the pair of the antenna 121 and the antenna 122 (or the pair of the antenna 121 ′ and the antenna 122 ′) arranged along the passage is a short distance determination or a proximity determination. If the portable terminal 111 notifies the automatic ticket checker 112 of the entry notification information at the timing, that is, the timing at which the received energy amounts of the reference signals of the antenna 121 and the antenna 122 both exceed the first threshold, the passer-by Can enter the area A4, and the automatic ticket gate 112 can execute the passage-side process.

  In addition, for example, the timing at which the distance determination results for the antenna 121 and the antenna 122 are both proximity determinations, that is, the received energy amounts of the reference signals of the antenna 121 and the antenna 122 both have the second threshold value. The mobile terminal 111 may notify the automatic ticket checker 112 of the entry notification information at a timing exceeding this. In the above-described legend, in the area A5, the distance determination is changed between the short distance determination and the long distance determination due to the influence of the human body and the surrounding environment. If the distance between the antenna 121 and the antenna 122 is narrowed, the automatic ticket checker 112 can be caused to execute the passage-side process at the timing when the passer-by enters the area A5.

  FIG. 9 is a schematic diagram showing a case where the portable terminal 111 is carried on the right side in the direction of passage for a passerby and is close to the human body of the passerby.

  In this case, the determination results of the antenna 121 and the antenna 121 ′ facing the left and right are larger in the area where the short distance determination or the proximity determination is performed on the side where the mobile terminal 111 approaches, and close on the side where the mobile terminal 111 is far away. A region for distance determination or proximity determination becomes narrower. The same applies to the antenna 122 and the antenna 122 '. Therefore, as in this embodiment, by arranging antenna sets on both sides of the passage 115, the energy of the reference signal is attenuated or the propagation path is detoured due to the influence of the human body, etc. Even if the radio field intensity from the other antenna group becomes weak, the radio field intensity from the other antenna group becomes sufficiently strong. Therefore, in the portable terminal 111, by selecting a set having a larger received energy amount of the reference signal from the set of antennas 121 and 122 and the set of antennas 121 ′ and 122 ′, the distance determination process is performed. It is possible to suppress the influence of the human body or the like and to grasp the entry position of the mobile terminal 111 more reliably.

  In the automatic ticket gate described above, the case of classifying the distance determination results for each antenna into three has been described, but more classifications or only two classifications may be used. If the number of classifications for distance discrimination is reduced, the processing load for distance discrimination on a mobile phone can be reduced, and mobile-side processing with high responsiveness can be performed. Further, if the number of distance determination classifications is increased, the number of positions that can be grasped as the entry position can be increased.

  In the above description, the case where the present invention is applied to a station management system has been described as an example. However, other systems such as a system for managing entry / exit to / from other facilities such as theme parks and event venues are described. The present invention can also be applied.
