Description

The present invention relates to a determination system, a determination device, and a determination method.

In the 3rd Generation Partnership Project (3GPP), the 5th generation (NR: Ne
w Radio) communication system is being studied (see Non-Patent Document 1). For such NR studies, specifications for beam management reporting including frequency bands higher than the 4th generation have been established (see Non-Patent Documents 2 and 3). Beams in frequency bands higher than the 4th generation propagate within a relatively limited range, and thus have potential applications in systems that provide services in localized areas. In particular, there is a demand for applications such as a system that enables touchless entry and exit of a specific passage, area, facility, or the like by using a communication terminal owned by a user.

<Configuration example of determination system 10>
FIG. 1 shows a configuration example of a determination system 10 according to this embodiment. The determination system 10 communicates with communication terminals existing within a predetermined area and determines whether or not a user possessing a communication terminal storing specific terminal information has passed a predetermined position. FIG. 1 shows an example in which the determination system 10 constitutes a touchless gate that communicates with a communication terminal 40 of a user 30 passing through a passageway 20 . The determination system 10 includes a gate 110 , a detection device 120 , a beam irradiation device 130 and a determination device 140 .

The gate 110 is provided in the passage 20 through which the user 30 passes. The gate 110 is provided with, for example, a partition plate, a door, a door, etc., which can be opened and closed. Alternatively, or in addition, the gate 110 may indicate passability, such as by sound and/or light. In addition, the gate 110 may indicate whether passage is allowed or not by means of a display unit or the like. The gate 110 is desirably controlled to open and close, for example, so that a person who is permitted to pass through can pass through. FIG. 1 shows an example in which walls 22 and 24 are provided at the boundary of passageway 20 and gate 110 is provided at one end of walls 22 and 24 .

A detection device 120 detects a person passing through the first location 50 . A first position 50 is a predetermined position on the passageway 20 . The first location 50 is located on the passageway 20 corresponding to the gate 110, for example. A first position 50 is a position that enables the detection device 120 to detect a person heading for the gate 110 . Thereby, the detection device 120 detects a person who passes the first position 50 and heads for the gate 110 on the passage 20 . FIG. 1 shows an example where the first location 50 is located at the end of walls 22 and 24 opposite the end where the gate 110 is located.

The detection device 120 has an infrared sensor 122 and a light source section 124 as an example. The light source unit 124 is provided at a position separated from the infrared sensor 122 by a predetermined distance, and emits infrared rays toward the infrared sensor 122 . In this case, the detection device 120 detects the passage of the person when the person passes between the infrared sensor 122 and the light source unit 124 and the output of the infrared sensor 122 is reduced. The detection device 120 has a sensor that detects visible light, ultrasonic waves, etc. instead of infrared rays, a sensor that detects vibrations and loads when a person passes by, a sensor that detects images such as a camera, and the like. may

The beam irradiation device 130 irradiates the first region 60 corresponding to the first position 50 with the frequency beam. The first area 60 is an area set in advance corresponding to the first position 50 so that a communication terminal owned by a person passing through the passage 20 can be irradiated with the frequency beam. The first area 60 includes, for example, at least a partial area above the passageway 20 . First region 60 preferably includes a region on passageway 20 that is closer to gate 110 than first location 50 . Also, the first region 60 may include the first location 50 . Further, first region 60 may include regions further from gate 110 than first location 50 . FIG. 1 shows an example where the first region 60 includes a first location 50 , a region closer to the gate 110 than the first location 50 , and a region further from the gate 110 than the first location 50 .

The beam irradiation device 130 irradiates the first region 60 with a frequency beam in a predetermined frequency band. The beam irradiation device 130 irradiates a frequency beam preset according to, for example, a communication standard. The frequency band of the frequency beam is a band including frequencies from several GHz to several tens of GHz. For example, the frequency band of the frequency beam may be a band containing frequencies from 10 GHz to 40 GHz, or a band containing frequencies from 20 GHz to 30 GHz. In addition, since the frequency beam is used in a local area, the frequency band of the frequency beam is preferably a higher frequency band, and may be a band including frequencies from 30 GHz to 40 GHz, or more than 40 GHz. It may be a band including frequencies.

The beam irradiation device 130 irradiates a frequency beam including beam identification information. The beam identification information is information for identifying the irradiated frequency beam. For example, the beam identification information has different information depending on the irradiated area. In the example of FIG. 1 , the beam irradiation device 130 irradiates the first region 60 with a frequency beam including beam identification information corresponding to the first region 60 . Accordingly, when the user 30 possessing the communication terminal 40 enters the first area 60 , the communication terminal 40 receives the frequency beam including the beam identification information corresponding to the first area 60 .

The beam irradiation device 130 may, for example, irradiate the frequency beam in a predetermined cycle, or alternatively, may irradiate the frequency beam according to a predetermined time schedule. Alternatively, the beam irradiation device 130 may continuously irradiate the frequency beam. Moreover, the beam irradiation device 130 may change the frequency of irradiation with the frequency beam according to the operation of the determination device 140 . For example, the beam irradiation device 130 irradiates the frequency beam more frequently when the determination device 140 is performing the determination operation than when the determination device 140 is not performing the determination operation. Also, the beam irradiation device 130 may irradiate a frequency beam in response to a request from the determination device 140 .

The determination device 140 determines whether or not the user 30 carrying the communication terminal 40 has passed through the predetermined position 70 . Here, the predetermined position 70 is, for example, a predetermined position within the first region 60 on the passage 20 . Predetermined location 70 is preferably located on passageway 20 between first location 50 and gate 110 . Also, the predetermined position 70 may be a position substantially equal to the first position 50 .

For example, the determination device 140 determines that the user 30 who wants to go beyond the gate 110 on the passage 20 has walked along the passage 20, passed the first position 50, and reached the predetermined position 70 in front of the gate 110. judge. The determination device 140 is, for example, a computer such as a server. The determination device 140 has a detection result reception section 210 , an information reception section 220 , a storage section 230 , a determination section 240 and a gate control section 250 .

The detection result receiving unit 210 receives the result of detecting a person passing through the first position 50 from the detection device 120 . The detection result receiving unit 210 is connected to the detecting device 120 by wire or wirelessly, for example. In this case, the detection result receiving unit 210 may be connected to the detection device 120 via a network.

The information receiving unit 220 receives beam identification information included in the frequency beam and terminal information stored in the communication terminal 40 from the communication terminal 40 that received the frequency beam irradiated to the first region 60 . That is, in the first area 60, the communication terminal 40, in response to receiving the frequency beam from the beam irradiation device 130, transmits the beam identification information of the frequency beam and the terminal information pre-stored in the communication terminal 40. It transmits to the receiving unit 220 .

The terminal information is unique information corresponding to the communication terminal 40 . The terminal information includes, for example, information as to whether or not passage to a passage extending from a predetermined position 70 in the traveling direction is permitted. The terminal information has a function as an entrance ticket, for example. Also, the terminal information may include information identifying the user 30 and/or the communication terminal 40 .

Here, the beam irradiation device 130 and the information receiving unit 220 are, for example, at least part of a base station that can communicate with the communication terminal 40 of the user 30 . Communication terminal 40 transmits beam identification information and terminal information to information receiving section 220 in accordance with the communication standard in response to reception of the frequency beam. Further, if necessary, the beam irradiation device 130, the information receiving section 220, and the communication terminal 40 may exchange other information. The communication terminal 40 is, for example, a communicable device such as a mobile phone, a smart phone, a game device, a tablet PC, a compact PC, a notebook PC, or the like.

The storage unit 230 stores the received beam identification information and terminal information. For example, the information receiving section 220 stores the information in the storage section 230 every time it receives beam identification information and terminal information. The storage unit 230 may also store the result of detecting a person passing through the first position 50 .

In addition, the storage unit 230 may store information on an OS (Operating System), in which a server or the like functions as the determination device 140, and application software. Further, the storage unit 230 may store various information including a database that is referred to when executing the application software. For example, a computer such as a server executes a program stored in the storage unit 230 to perform at least part of the detection result reception unit 210, the information reception unit 220, the storage unit 230, the determination unit 240, and the gate control unit 250. function as

The storage unit 230 includes, for example, a ROM (Read Only Memory) that stores a BIOS (Basic Input Output System) of a computer or the like, and a RAM (Random Access Memory) that serves as a work area. The storage unit 230 may also include a large-capacity storage device such as a HDD (Hard Disk Drive) and/or an SSD (Solid State Drive). Also, the computer may further include a GPU (Graphics Processing Unit) or the like.

In addition, the storage unit 230 may store information such as setting values used by the determination device 140 . The storage unit 230 may also store intermediate data generated (or used) in the process of the operation of the determination device 140, calculation results, thresholds, parameters, and the like. In addition, the storage unit 230 may supply the stored data to the request source in response to requests from each unit in the determination device 140 . Furthermore, the storage unit 230 may supply the stored data to the request source in response to a request from each unit within the determination system 10 .

The determination unit 240 determines the predetermined position 70 corresponding to the first position 50 by the user 30 based on the beam identification information and the terminal information transmitted by the communication terminal 40 during the period corresponding to the timing when the detection device 120 detects the person. Determine whether or not it has passed. For example, the determination unit 240 determines whether the user 30 has passed through the predetermined position 70 based on the beam identification information and the terminal information received immediately before and/or after the detection timing at which the detection device 120 detects a person. judge. As an example, the determination unit 240 determines that the user 30 has passed through the predetermined position 70 when the beam identification information received immediately after the detection timing of the detection device 120 is information corresponding to the first region 60 .

Further, determination section 240 determines whether or not user 30 has passed through predetermined position 70 based on beam identification information and terminal information received during a predetermined period immediately before and/or after the detection timing. You may For example, the information receiving unit 220 continuously receives the beam identification information from the communication terminal 40 of the user 30, and the determination unit 240 determines whether the user 30 passes through the predetermined position 70 based on the result of continuous reception of the beam identification information. determine whether or not As an example, while the information receiving unit 220 continues to receive the beam identification information corresponding to the first region 60, the detection result receiving unit 210 receives the detection result of the person at the first position 50. Then, the determination unit 240 determines that the user 30 has passed through the predetermined position 70 .

The gate control unit 250 controls opening and closing of the gate 110 based on the terminal information of the user 30 determined to have passed through the predetermined position 70 . For example, the gate control unit 250 opens the gate 110 when the terminal information of the user 30 includes information permitting passage beyond the gate 110 . It is assumed that the information indicating permission to pass is stored in advance in the communication terminal 40 by the determination system 10 or a system different from the determination system 10 or the like.

The determination system 10 described above receives the beam identification information transmitted from the communication terminal 40 based on the frequency beam irradiated to the first region 60 corresponding to the first position 50, and the user 30 having the communication terminal 40 has entered the first region 60 . However, since the frequency beam propagates with a certain spread, communication terminals 40 outside the first area 60 may receive it. In addition, since the frequency beam may be reflected by people, walls, etc., the communication terminal 40 outside the first area 60 may receive the signal in this case as well.

In this case, if only the beam identification information is used, the determination system 10 may erroneously determine that the user 30 has entered the first area 60 even if the user 30 is outside the first area 60 . Therefore, if the determination system 10 is applied to a touchless gate or the like based only on the beam identification information, the gate 110 may be opened even if the user 30 is not moving on the passage 20 . If such a malfunction occurs, for example, another person who does not have the communication terminal 40 may pass through the gate 110 .

Therefore, the determination system 10 according to the present embodiment ensures that the user 30 who has entered the first region 60 has entered the first region 60 based on the detection result of the person at the first position 50 of the detection device 120. to judge. Thereby, the determination system 10 can determine that the user 30 who has entered the first area 60 passes through the predetermined position 70 from the first position 50 and is heading for the gate 110 . In this way, when the user 30 who wants to pass through the gate 110 passes through the passage 20, the determination system 10 appropriately determines the movement of the user 30 and controls the opening/closing of the gate 110 based on the terminal information. An operation flow of such a determination system 10 will be described below.

<Operation flow of determination system 10>
FIG. 2 shows an example of the operation flow of the determination system 10 according to this embodiment. In this embodiment, an example will be described in which the determination system 10 executes the operation flow shown in FIG. 2 and functions as a touchless gate used for a ticket gate at a station or the like.

First, the beam irradiation device 130 irradiates the first region 60 with a frequency beam (S210). Here, the first region 60 includes the first position 50, a region closer to the gate 110 than the first position 50, and a region farther from the gate 110 than the first position 50, as described in FIG. area. Accordingly, when the user 30 enters the first area 60, the communication terminal 40 possessed by the user 30 receives the frequency beam. Upon receiving the frequency beam from the beam irradiation device 130 , the communication terminal 40 transmits beam identification information of the frequency beam and terminal information pre-stored in the communication terminal 40 to the information receiving section 220 .

The determination system 10 thus waits for the user 30 to enter the first area 60 . That is, the determination system 10 confirms whether or not the beam identification information and the terminal information from the communication terminal 40 have been received (S220). If the information receiving unit 220 does not receive the beam identification information and the terminal information from the communication terminal 40 (S220: No), the determination system 10 returns to S210. The determination system 10 repeats the operations of S210 and S220 until the information receiving section 220 receives the beam identification information and the terminal information from the communication terminal 40. FIG. When the information receiving unit 220 receives the beam identification information and the terminal information from the communication terminal 40 (S220: Yes), the determination system 10 stores the received information in the storage unit 230. FIG.

Determination system 10 then waits for user 30 to pass first location 50 . That is, the determination system 10 confirms whether or not the detection result reception unit 210 has received the detection result of the person from the detection device 120 (S230). If the detection result receiving unit 210 does not receive the detection result from the detection device 120 (S230: No), the determination system 10 returns to S210. In this case, the user 30 has entered the first area 60 but has not advanced to the first position 50 .

Such a user 30 may move outside the first area 60 . Also, the user 30 may be receiving frequency beams outside the first region 60 . Therefore, the determination system 10 repeats the operations from S210 to S230 until the user 30 moves to the first position 50 to continuously receive beam identification information and terminal information. Also, when the user 30 moves out of the first area 60 , the operations from S<b>210 to S<b>230 are repeated until the same user 30 or a different user 30 moves into the first area 60 .

When the detection result reception unit 210 receives the detection result of the person detected by the detection device 120 (S230: Yes), the determination system 10 determines whether or not the user 30 has passed through the predetermined position 70 (S240). For example, when the beam identification information received by the information receiving unit 220 immediately after or immediately before the detection result receiving unit 210 receives the detection result of the detecting device 120 is information corresponding to the first region 60, the determining unit 240 causes the user 30 has passed a predetermined position 70.

Here, when the user 30 enters the first area 60 and a person is detected at the first position 50 , there is a high possibility that the detected person is the user 30 . Therefore, when the determination unit 240 receives the beam identification information corresponding to the first region 60 at a timing close to the detection timing of the person, the detected person is the user 30 who has entered the first region 60, It is determined that the user 30 has passed the first position 50 and the predetermined position 70 on the passage 20 (S240: Yes).

In addition, the distance between the first position 50 and the predetermined position 70 is the distance between the user 30 and the timing when the detector 120 detects the person and the next timing when the information receiving unit 220 receives the beam identification information. It is desirable that the distance is less than or equal to the distance that 30 travels. Also, the first position 50 and the predetermined position 70 may coincide, or alternatively, the predetermined position 70 may be farther from the gate 110 than the first position 50 .

Even if the user 30 enters the first area 60 and a person is detected at the first position 50 , the information receiver 220 may not receive the beam identification information corresponding to the first area 60 . For example, a person without a communication terminal 40 may pass through the first position 50 . In this case, even if a person is detected, the information receiving section 220 cannot receive the beam identification information, so the determination section 240 does not determine that the user 30 has passed the predetermined position 70 (S240: No).

If the determination unit 240 does not determine that the user 30 has passed through to the predetermined position 70 (S240: No), the gate control unit 250 closes the gate 110 or keeps the gate 110 closed (S250). . If the gate 110 or the like is provided with a display unit or the like, the gate control unit 250 may cause the display unit to display that the passage is prohibited. In addition, the gate control unit 250 may notify by voice or the like that the road is impassable. In addition, the gate control unit 250 may notify a manager, user, operator, etc. around the gate 110 that a person who cannot pass through is coming to the gate 110 .

If the determination unit 240 determines that the user 30 has passed through to the predetermined position 70 (S240: Yes), the gate control unit 250 checks the terminal information of the user 30 (S260). For example, if the terminal information does not include information permitting passage beyond passage 20 (S260: No), gate control unit 250 either closes gate 110 or keeps gate 110 closed (S250). .

For example, when the determination system 10 is provided at a ticket gate of a station, the gate control unit 250 determines that the terminal information includes information for boarding a train such as a fare, ticket and commuter pass, and information for entering the station such as an admission ticket. Confirm whether or not information is included. If the terminal information includes such information permitting passage beyond the passage 20 (S260: Yes), the gate control unit 250 opens the gate 110 (S270). As a result, the user 30, whose communication terminal 40 records in advance the information that the gate 110 can be passed as terminal information, can pass through the gate 110 only by carrying the communication terminal 40 and walking along the passage 20. - 特許庁That is, the determination system 10 can function as a touchless gate.

A touchless gate provided at a station ticket gate or the like settles the fare and the like based on the entrance and exit of the user 30 . Therefore, the gate control unit 250 may notify the information of the user 30 to such an external billing system or the like based on the opening/closing of the gate 110 . Similarly, if a management system or the like that manages the entrance and exit of the user 30 is provided outside, the gate control unit 250 notifies the management system of information on the user 30 based on the opening and closing of the gate 110. may

In the determination system 10 according to the present embodiment described above, the beam irradiation device 130 separates the first position 50, an area closer to the gate 110 than the first position 50, and an area farther from the gate 110 than the first position 50 into An example of irradiating the first region 60 with a frequency beam has been described. However, the first region 60 irradiated with the frequency beam by the beam irradiation device 130 is not limited to this. First region 60 may be a region including first location 50 and a region closer to gate 110 than first location 50 . Also, the first region 60 may be the first location 50 or a region closer to the gate 110 than the first location 50 . In these cases, in the operation flow shown in FIG. 2, the operations of S210 and S220 are executed after the operation of S230. Such an operation flow will be described below.

<Modified Example of Operation Flow of Determination System 10>
FIG. 3 shows a modification of the operation flow of the determination system 10 according to this embodiment. In the operation flow of this modified example, the same reference numerals are assigned to the operations that are substantially the same as those of the operation flow of the determination system 10 according to the present embodiment shown in FIG. 2, and the description thereof is omitted.

In the operation flow of this modified example, first, the detection result receiving unit 210 waits for the detection result of the person by the detection device 120 (S310). The detection result receiving unit 210 repeats the operation of waiting for the detection result until it receives the detection result of the person at the first position 50 from the detection device 120 (S310: No).

When the detection result receiving unit 210 receives the detection result from the detection device 120 (S310: Yes), the beam irradiation device 130 irradiates the first region 60 with the frequency beam (S210). Note that the irradiation of the frequency beam by the beam irradiation device 130 may be performed before the detection result reception unit 210 waits for the detection result of the person by the detection device 120 in S310.

Next, the information receiving section 220 waits for transmission of beam identification information and terminal information from the communication terminal 40 (S320). The information receiving unit 220 waits for transmission from the communication terminal 40 for a predetermined period, for example. When receiving beam identification information and terminal information from communication terminal 40 , information receiving section 220 stores the received information in storage section 230 . Here, the information receiving unit 220 only needs to wait for transmission from the communication terminal 40 for a predetermined period of time, and regardless of whether beam identification information and terminal information are transmitted, the determination system 10 proceeds to the next operation of S330. .

Next, the determination unit 240 determines whether or not the user 30 has passed through the predetermined position 70 (S330). For example, if the beam identification information received by the information receiving section 220 is information corresponding to the first area 60, the determination section 240 determines that the user 30 has passed through the predetermined position 70 (S330: Yes). That is, since the information receiving unit 220 receives the beam identification information corresponding to the first region 60 after the detector 120 detects that the person has passed the first position 50 in the first region 60, the first The person detected at position 1 50 is most likely user 30 .

On the other hand, when the information receiving unit 220 has not received the beam identification information corresponding to the first region 60 since the detection device 120 detected that the person passed the first position 50 of the first region 60 , the determination unit 240 does not determine that the user 30 has passed the predetermined position 70 (S330: No). That is, even if a person is detected at the first position 50, if the information receiving unit 220 does not receive the beam identification information, the determination unit 240 determines that the detected person does not have the communication terminal 40. do.

If the determination unit 240 does not determine that the user 30 has passed through to the predetermined position 70 (S330: No), the gate control unit 250 closes the gate 110 or keeps the gate 110 closed (S250). . If the determination unit 240 determines that the user 30 has passed through to the predetermined position 70 (S330: Yes), the gate control unit 250 checks the terminal information of the user 30 (S260). Since the operations from S250 to S270 have already been described with reference to FIG. 2, the description thereof will be omitted here. As described above, the determination system 10 according to this modification can also function as a touchless gate.

Although the determination system 10 according to the present embodiment has been described as an example in which the beam irradiation device 130 irradiates the first region 60 with the frequency beam, the determination system 10 is not limited to this. The beam irradiation device 130 may irradiate a region different from the first region 60 with a frequency beam including beam identification information different from that of the first region 60 . For example, the beam irradiation device 130 irradiates a plurality of different regions with frequency beams including beam identification information that differs for each region.

Accordingly, for example, when the user 30 travels toward the first area 60 from an area different from the first area 60, the information receiving unit 220 receives different beam identification information according to the area through which the user 30 passes. It will be. Therefore, the determination unit 240 can predict the position of the user 30 based on changes in the beam identification information received by the information reception unit 220 . Thus, the determination unit 240 can determine whether the user 30 is traveling toward the first area 60 by analyzing continuous changes in the beam identification information received by the information reception unit 220 .

Therefore, for example, in the operation of S240 in FIG. 2, if the determination unit 240 determines that the user 30 is traveling toward the first region 60 before the timing at which the detection device 120 detects a person, It is determined that the user 30 has passed the predetermined position 70 . This makes it possible to more reliably determine that the user 30 has proceeded in front of the gate 110 .

It should be noted that the determination system 10 described above can operate as a touchless gate in the same manner even when used by a plurality of users 30 . In this case, the information receiving unit 220 receives beam identification information and terminal information from one or a plurality of communication terminals 40 that have received the frequency beam among the plurality of communication terminals 40 possessed by each of the plurality of users 30 . Then, the determination unit 240 determines whether or not the corresponding one or more users 30 have passed through the predetermined position 70 based on the reception result of the one or more beam identification information.

Thus, the determination system 10 can determine whether or not a plurality of users 30 carrying communication terminals 40 have each advanced to the gate 110 , and can open/close the gate 110 according to the terminal information of each user 30 . When multiple users 30 use the touchless gate, multiple users 30 may arrive in front of one gate 110 almost at the same time. In this case, the determination system 10 according to the present embodiment can acquire terminal information from the communication terminals 40 owned by the plurality of users 30, so control can be executed according to the plurality of terminal information.

When there are a plurality of users 30 determined to have passed through the predetermined position 70 , the gate control unit 250 controls opening and closing of the gate 110 based on the terminal information of the plurality of users 30 . For example, the gate control unit 250 opens the gate 110 when all the terminal information of the plurality of users 30 permits passage through the gate 110 . As a result, the determination system 10 allows a plurality of users 30 permitted to pass through the gate 110 simply by moving to the gate 110 .

Further, the gate control unit 250 closes the gate 110 when one or more terminal information among the terminal information of the plurality of users 30 is not information permitting passage through the gate 110 . Thereby, the determination system 10 can prevent a person who is not permitted to pass from moving to the gate 110 together with a person who is permitted to pass and passing through the gate 110 .

As described above, the determination system 10 can determine whether passage is permitted by using terminal information. However, a person who is not permitted to pass may attempt to pass through the gate 110 by illegally possessing another person's communication terminal 40 . In addition, a person who is not permitted to pass may move to the gate 110 almost at the same time as the user 30 who is permitted to pass without holding the communication terminal 40 and attempt to pass through the gate 110 . The determination system 10 according to this embodiment may be configured to prevent fraud such as impersonation. Such a determination system 10 will now be described.

<First modification of determination system 10>
FIG. 4 shows a first modification of the determination system 10 according to this embodiment. In the determination system 10 of the first modified example, the same reference numerals are assigned to the operations that are substantially the same as those of the determination system 10 according to the present embodiment shown in FIG. 1, and the description thereof is omitted. The determination system 10 of the first modified example includes an imaging device 410 . The determination device 140 also has a user authentication unit 420 .

The imaging device 410 is provided at a second position 80 spaced apart from the gate 110 by a predetermined distance, and images a person passing through the passage 20 . The imaging device 410 is a camera or the like, and desirably captures at least the face of a person passing through the passage 20 . For example, the imaging device 410 images the face of a person who has come to the front of the gate 110 . Moreover, when a plurality of people come to the front of the gate 110, the imaging device 410 is preferably capable of capturing the faces of the plurality of people.

The second position 80 is preferably a position such that the imaging device 410 can image a person who has come in front of the first position 50 , the predetermined position 70 , and/or the gate 110 from the front. The second position 80 is, for example, a position further from the first position 50 than the gate 110 . For example, on passageway 20, first location 50, gate 110, and second location are arranged side by side in this order.

The imaging device 410 may capture an image of the person in response to the detection device 120 detecting the person passing through the first position 50 . In this case, for example, the detection result receiving unit 210 may notify the imaging device 410 of the imaging instruction, or alternatively, the detecting device 120 may notify the imaging device 410 of the imaging instruction. Further, the imaging device 410 may capture an image of a person passing through the first position 50 with a delay of a predetermined time from the timing at which the detection device 120 detects the person passing through the first position 50 . As a result, the imaging device 410 can capture an image of a person traveling through the passage 20 at a position closer to the gate 110 . The imaging device 410 stores, for example, image information of the captured image in the storage unit 230 .

Image information of the user 30 is stored in advance in the storage unit 230 of the first modified example. For example, the determination system 10 or a system different from the determination system 10 acquires the image information of the user 30 when supplying terminal information indicating permission to pass to the communication terminal 40 of the user 30 in advance, and stores the information in the storage unit. It is desirable to store 230. Thereby, the terminal information of the user 30 and the image information of the user 30 can be associated in advance and stored in the storage unit 230 .

The user authentication unit 420 authenticates a person passing through the passage 20 based on the image information of the user 30 and the imaging result of the imaging device 410 . For example, the user authentication unit 420 authenticates a person passing through the passage 20 when the imaging device 410 captures an image of the person. In this case, the user authentication unit 420 receives the timing to start user authentication from the detection result receiving unit 210 or the imaging device 410, for example.

The user authentication unit 420 authenticates whether or not the person passing through the passage 20 is the user 30 by image processing of a face image or the like. Further, when image information of a plurality of users 30 is stored in the storage unit 230, the user authentication unit 420 authenticates each of the plurality of image information and the captured image. If any one of the plurality of pieces of image information and the captured image are successfully authenticated, the user authentication unit 420 supplies the gate control unit 250 with information indicating that the authentication was successful. The user authentication unit 420 may also supply the terminal information of the authenticated user 30 to the gate control unit 250 . If the captured image could not be authenticated, the user authentication section 420 supplies the gate control section 250 with information indicating that the authentication was not successful.

The gate control unit 250 of the first modified example further uses the authentication result of the person passing through the passage 20 to control the opening and closing of the gate 110 . The gate control unit 250 opens the gate 110 when the terminal information of the user 30 includes information permitting passage to the end of the passage 20 and the captured image is authenticated. In addition, the gate control unit 250 cannot authenticate the captured image when the terminal information of the user 30 does not include information permitting passage to the end of the passage 20 or even when the terminal information includes information permitting passage. If so, the gate 110 is closed.

Thereby, the determination system 10 of the first modified example can prevent the user 30 from being impersonated. The gate control unit 250 may further compare the terminal-specific information of the user 30 received by the information receiving unit 220 with the terminal-specific information acquired by the user authentication unit 420 through authentication. As a result, the determination system 10 can also prevent impersonation between registered users.

Further, when the image captured by the imaging device 410 includes facial images of a plurality of people, the user authentication section 420 may perform authentication for each of the facial images. In this case, the gate control unit 250 opens the gate 110 when all the terminal information of the plurality of users 30 includes information permitting passage to the end of the passage 20 and all face images are authenticated. As a result, the determination system 10 can appropriately control the opening and closing of the gate 110 even if a person who does not possess the communication terminal 40 slips into the plurality of users 30 .

Further, when the captured image of the imaging device 410 includes face images of a plurality of people, the user authentication unit 420 determines the number of people included in the captured image as the number of people who have passed through the predetermined position 70, and the gate control unit 250 may be notified to When the number of terminal information items of a plurality of users 30 matches the number of people who have passed through the predetermined position 70 and all the terminal information items include information permitting passage to the end of the passage 20, the gate control unit 250 Open gate 110 . Even in this case, if a person who does not have a communication terminal 40 is mixed in with a plurality of users 30, the determination system 10 can appropriately control the opening and closing of the gate 110 because the number of terminal information is reduced. can be done.

Further, the determination system 10 of the first modified example may discard the stored information of the user 30 after a certain period of time has elapsed or a certain action has ended. For example, when the gate control unit 250 opens the gate 110 and allows the user 30 to pass through, the gate control unit 250 erases the image information of the user 30 stored in the storage unit 230 . This allows the determination system 10 to eliminate unnecessary information and reduce the storage capacity required for the system. In addition, the determination system 10 can reduce risks such as leakage of personal information.

Although the determination system 10 according to the present embodiment described above has a configuration example in which one gate 110 is provided, the configuration is not limited to this. The determination system 10 may include a plurality of gates 110, and a corresponding plurality of imaging devices 410 may also be provided. Such a determination system 10 will now be described.

<Second Modification of Determination System 10>
FIG. 5 shows a second modification of the determination system 10 according to this embodiment. In the determination system 10 of the second modified example, the substantially same operations as those of the determination system 10 shown in FIGS. 1 and 4 are denoted by the same reference numerals, and description thereof is omitted. The determination system 10 of the second modification includes a plurality of passages 20 and a plurality of gates 110 and a plurality of detection devices 120 corresponding to the plurality of passages 20 . FIG. 5 shows an example with two passages 20 and two gates 110 and two detectors 120 corresponding to the two passages 20 .

A plurality of gates 110 are provided in a plurality of passages 20 through which the user 30 passes. Each of the plurality of gates 110 is provided to be openable and closable by a control signal from the gate control section 250 . A plurality of detection devices 120 are provided at a plurality of predetermined positions corresponding to the plurality of passages 20, respectively. Each detection device 120 detects a person passing through the corresponding passageway 20 . Here, the plurality of positions are arranged on the plurality of passages 20 corresponding to the plurality of gates 110 respectively.

The beam irradiation device 130 irradiates a plurality of predetermined regions corresponding to each of the plurality of positions where the detection device 120 is provided with frequency beams including beam identification information that differs for each region. Each of the multiple areas includes a partial area on the corresponding one of the multiple paths 20 . It is desirable that the multiple regions are predetermined so as not to overlap each other. Therefore, when the determination system 10 is in an ideal communication environment free from influences such as reflection, the communication terminal 40 possessed by the user 30 passing through the one passage 20 receives the frequency beam, beam identification information and terminal information associated with the path 20 are transmitted to the information receiving unit 220 .

The information receiving unit 220 receives beam identification information and terminal information from one or a plurality of communication terminals 40 that have received frequency beams among the plurality of communication terminals 40 owned by each of the plurality of users 30 . For example, when the first user 30a enters the area 60a corresponding to the position a where the first detection device 120a is provided in the first passage 20a, the first communication terminal 40a possessed by the first user 30a corresponds to the position a. The beam identification information and the terminal information to be transmitted to the information receiving unit 220 . Further, for example, when the second user 30b enters the area 60b corresponding to the position b where the second detecting device 120b is provided in the second passage 20b, the second communication terminal 40b possessed by the second user 30b is located at the position b. to the information receiving unit 220. The beam identification information corresponding to . In this case, the information receiving section 220 receives information transmitted from the first communication terminal 40a and the second communication terminal 40b.

The determination unit 240 determines whether or not the corresponding one or more users 30 have passed through a predetermined position 70 corresponding to at least one position among a plurality of positions, based on the reception result of one or more beam identification information. judge. For example, in response to transmission of beam identification information corresponding to position a by the first communication terminal 40a during a period corresponding to the timing when the first detection device 120a detects the passage of a person at position a, the determination unit 240 , determines whether or not the first user 30a has passed through a predetermined position 70a corresponding to the position a. Similarly, in response to transmission of beam identification information corresponding to position b from second communication terminal 40b during a period corresponding to the timing at which second detection device 120b detects the passage of a person at position b, determination unit 240 determines whether the second user 30b has passed the predetermined position 70b corresponding to the position b.

Based on the terminal information of one or more users 30 determined to have passed through at least one predetermined position 70 out of a plurality of predetermined positions 70 corresponding to a plurality of positions, the gate control unit 250 controls the at least one It controls the opening and closing of gates 110 corresponding to two predetermined positions 70 . For example, when the determination unit 240 determines that the first user 30a has passed through the predetermined position 70a, the gate control unit 250 determines that if the terminal information of the first user 30a includes information permitting passage, the first user 30a Open the gate 110a. Further, for example, when the determination unit 240 determines that the second user 30b has passed through the predetermined position 70b, the gate control unit 250 determines that if the terminal information of the second user 30b does not include information permitting passage, Close the second gate 110b.

As described above, the determination system 10 of the second modification has the passages 20 shown in FIG. Thereby, the determination system 10 of the second modified example can function as a touchless gate that can be used by more users 30 per unit time.

The determination system 10 of the second modified example may further include a plurality of imaging devices 410 . In this case, the plurality of imaging devices 410 are provided at a plurality of positions separated from each of the plurality of gates 110 by a predetermined distance, and respectively capture images of people passing through the plurality of passages 20 . In this case, the user authentication unit 420 authenticates one or a plurality of persons passing through the passages 20 based on the image information of the user 30 and the imaging results of the imaging devices 410 respectively. The gate control unit 250 further uses the person authentication result of the user authentication unit 420 to control opening and closing of the plurality of gates 110 .

As described above, the determination system 10 of the second modification has the passages 20 shown in FIG. You may control opening and closing. As a result, the determination system 10 of the second modification can function as a touchless gate that can be used by more users 30 per unit time while preventing fraud such as impersonation of the user 30 .

The determination system 10 according to the present embodiment described above can be used not only as ticket gates at stations, but also as touchless gates at airports, boarding areas, stadiums, playgrounds, concert halls, conference halls, and the like. Also, the determination system 10 may be used as a gate at the entrance of a specific room such as a lounge, conference room, examination hall, or the like. In this case, the gate 110 may not have a special partition, and may be an automatic door or the like. Also, instead of the gate 110 , a staff member or the like may be arranged, and the gate control unit 250 may notify the staff member of an instruction to open or close the gate 110 .
