<Operation example>
FIG. 6 is a diagram showing an example of the operation flow of the door management server 50 of the door management system 1 of this embodiment. Here, it is assumed that the user who wants to enter the first area exists in the second area. It is assumed that users wearing portable beacons 80 and users not wearing portable beacons 80 can exist in the second area. It is assumed that the user wearing the portable beacon 80 wears the portable beacon 80 on the front side (chest side) of the body. Also, here, it is assumed that the door 70 is closed and locked by the unlocking device 60 . The mobile beacon 80 constantly (for example, every second) transmits a signal containing identification information for identifying the mobile beacon 80 .

In S101, the controller 51 of the door management server 50 determines whether or not the human sensor 20 has detected the presence of a person. The human sensor 20 is installed near the door 70 separating the first area and the second area and on the second area side. The human sensor 20 constantly detects the presence or absence of a person existing in the second area near the door 70 . The human sensor 20 transmits a signal including the detection result of the presence of a person to the human sensor management server 40 . Upon receiving the signal from the human sensor 20 via the communication unit 42 , the control unit 41 of the human sensor management server 40 stores the detection result included in the received signal in the storage unit 43 . The control unit 41 transmits the received signal to the door management server 50 via the communication unit 42 . The control unit 51 of the door management server 50 receives a signal from the human sensor management server 40 via the communication unit 52 . Control unit 51 stores the detection result included in the received signal in storage unit 53 . The control unit 51 confirms whether or not the detection result of the received signal indicates presence of a person. If a person exists (S101; YES), the process proceeds to S102. If no person exists (no person exists) (S101: NO), the process of S101 is repeated.

In S102, the control unit 51 determines whether the signal strength of the signal received by the beacon receiver 10 is equal to or greater than a threshold. The beacon receiver 10 is installed, for example, near the door 70 separating the first area and the second area and on the wall on the side of the second area. The threshold is set when the front (chest side) of the user carrying the portable beacon 80 faces the beacon receiver 10 and the distance from the portable beacon 80 to the beacon receiver 10 is a predetermined distance. is determined as the received strength of The predetermined distance is, for example, the distance at which the user is considered to be in front of the door 70 and is about to enter the first area through the door 70 . When the front (chest side) of the user does not face the beacon receiver 10, the radio waves from the portable beacon 80 received by the beacon receiver 10 pass through the user's body. When radio waves pass through the user's body, the strength of the radio waves becomes smaller than when they pass through the air. At this time, even if the distance between the mobile beacon 80 and the beacon receiver 10 is a predetermined distance, the reception strength of the radio wave (signal) from the mobile beacon 80 at the beacon receiver 10 is less than the threshold. The fact that the front (chest side) of the user carrying the portable beacon 80 faces the beacon receiver 10 means, for example, that the portable beacon 80 carried by the user can be visually recognized from the position of the beacon receiver 10. .

Furthermore, the control unit 51 determines whether or not the user carrying the portable beacon 80 that transmitted the received signal is permitted to enter the first area.

The beacon receiver 10 receives a signal transmitted from a portable beacon 80 carried by a user. The signal includes identification information that identifies the portable beacon 80 . The identification information is associated in advance with the user carrying the portable beacon 80 . The identification information is information corresponding to the user carrying the portable beacon 80 . Also, the beacon receiver 10 measures the reception strength of the received signal. The beacon receiver 10 transmits to the beacon management server 30 a signal including identification information included in the received signal and the reception strength of the signal. The control unit 31 of the beacon management server 30 receives signals from the beacon receiver 10 via the communication unit 32 . The control section 31 of the beacon management server 30 stores the received signal in the storage section 33 . The control unit 31 of the beacon management server 30 transmits the received signal to the door management server 50 via the communication unit 32 .

Control unit 51 of door management server 50 receives a signal from beacon management server 30 via communication unit 52 . The control unit 51 of the door management server 50 stores the identification information and the reception intensity contained in the received signal in the storage unit 53 . The control unit 51 of the door management server 50 determines whether or not the reception intensity included in the received signal is equal to or greater than the threshold. If it is less than the threshold, the control unit 51 determines that there is no user near the door 70 trying to enter the first area. Moreover, when it is more than a threshold value, the control part 51 determines that the user who is going to enter a 1st area|region exists in the vicinity of the door 70. FIG. Further, if the threshold is greater than or equal to the threshold, the control unit 51 causes the storage unit 53 to store identification information for identifying the portable beacon 80 included in the received signal (identification information corresponding to the user carrying the portable beacon 80). is included in the identification information of the user who is permitted to enter the first area (permitted user identification information). If it is included, the control unit 51 determines that the user who is permitted to enter the first area exists near the door 70 trying to enter the first area. If it is not included, it is determined that there is no user permitted to enter the first area near the door 70 trying to enter the first area. If it is determined that a user who is permitted to enter the first area exists near the door 70 to enter the first area (S102; YES), the process proceeds to S103. If it is determined that the user permitted to enter the first area does not exist near the door 70 to enter the first area (S102; NO), the process returns to S101. Note that when it is determined that a user permitted to enter the first area does not exist in the vicinity of the door 70 trying to enter the first area, the case where the reception intensity is less than the threshold is also included. . The reception intensity threshold determines the area near the door 70 where a user who tries to enter the first area exists. The larger the threshold, the smaller the area. The area may be larger than the range in which the human sensor 20 detects a person. By making the area larger than the range in which the human sensor 20 detects a person (that is, by making the threshold value smaller), the person detected by the human sensor 20 is permitted to enter the first area. It is possible to detect users without omission. At this time, the threshold is the signal transmitted from the portable beacon 80 carried by the user facing the beacon receiver 10 at any position within the range where the human sensor 20 detects the presence of a person. A value less than the signal strength at the beacon receiver 10 . Further, by using the human detection sensor 20, even if the threshold value of the reception intensity is reduced to relax the determination that there is a user trying to enter the first area near the door 70, Unlocking of the door 70 can be suppressed when there is no user.

Here, the controller 51 of the door management server 50 attempts to enter the first area in the vicinity of the door 70 when continuously receiving a signal whose reception intensity is equal to or higher than the threshold for a predetermined time (for example, 3 seconds). It may be determined that there is a user with As a result, for example, a user who has passed the vicinity of the door 70 without intending to enter the first area can be excluded. For example, when the portable beacon 80 transmits a signal every second, the control unit 51 receives a signal whose reception strength is equal to or greater than the threshold value three times within three seconds. It is determined that there is a user trying to enter the first area at .

Although one beacon receiver 10 is used here, a plurality of beacon receivers 10 may be installed. When a plurality of beacon receivers 10 are installed, a user existing in a specific area near the door 70 can be detected more appropriately by appropriately setting the threshold of reception intensity for each. For example, in the example of FIG. 1, since the beacon receiver 10 is installed on the right side of the door 70, a user existing near the door 70 on the left side of the beacon receiver 10 and a user existing on the right side of the beacon receiver 10 It is difficult to distinguish from users (users who do not exist near the door 70). On the other hand, for example, by installing the beacon receiver 10 on the left side of the door 70 as well, only users existing near the door 70 can be detected. When received by the beacon receiver 10 on the left side of the door 70 , the reception strength of the radio waves from the mobile beacon 80 carried by the user, which is on the right side of the beacon receiver 10 on the right side of the door 70 , is the same as that of the radio waves from near the door 70 is considered to be smaller than the reception strength of Therefore, by setting the threshold between these two reception intensities, the user on the right side of the beacon receiver 10 on the right side of the door 70 (the user who is not near the door 70) and the beacon on the right side of the door 70 A user on the left side of the receiver 10 (a user near the door 70) can be distinguished.

In S<b>103 , the control unit 51 of the door management server 50 instructs the unlocking device 60 via the communication unit 52 to unlock the door 70 . The unlocking device 60 unlocks the door 70 upon receiving the unlocking instruction from the door management server 50 . As a result, a user carrying the portable beacon 80 (a user permitted to enter the first area) can open the door 70 and enter the first area. The unlocked door 70 is ready to be opened by the user. Further, the unlocking device 60 may unlock the door 70 and open the door 70 (open state). A user carrying a portable beacon 80 can enter the first area through an opening between the first area and the second area. Further, the control unit 51 of the door management server 50 may associate the identification information of the user with information on the time when the door 70 was unlocked and store the information in the storage unit 53 . The door management server 50 can manage the time when each user enters the first area by storing user identification information and the time when the door 70 is unlocked.

In S104, the controller 51 of the door management server 50 determines whether or not the human sensor 20 has detected the presence of a person. The human sensor 20 transmits a signal including the detection result of the presence of a person to the human sensor management server 40 . Upon receiving the signal from the human sensor 20 via the communication unit 42 , the control unit 41 of the human sensor management server 40 stores the received signal in the storage unit 43 . The control unit 41 transmits the received signal to the door management server 50 via the communication unit 42 . The control unit 51 of the door management server 50 receives a signal from the human sensor management server 40 via the communication unit 52 . Control unit 51 stores the received signal in storage unit 53 . The control unit 51 confirms whether or not the detection result of the received signal indicates presence of a person. If a person exists (S104; YES), the process of S104 is repeated. At this time, it is assumed that the user exists near the door 70 and the user has not yet passed through the opening between the first area and the second area. If no person exists (no person exists) (S104: NO), the process proceeds to S105. At this time, it is considered that the user who is permitted to enter the first area has entered the first area through the opening between the first area and the second area.

In S<b>105 , the control unit 51 of the door management server 50 instructs the unlocking device 60 via the communication unit 52 to lock the door 70 . The unlocking device 60 locks the door 70 upon receiving the locking instruction from the door management server 50 . The locked door 70 cannot be opened by the user. This prevents the user from going back and forth between the first area and the second area. Further, the unlocking device 60 may close the door 70 (put it in a closed state) and lock the door 70 . This can prevent a user or the like who is not permitted to enter the first area from entering the first area from the second area.

In the operation flow described above, some processes may be omitted, or the order of the processes may be changed. For example, the order of S101 and S102 may be changed.

The beacon receiver 10 and the human sensor 20 may also be installed on the side of the first area, and the same may be done when the user enters the second area from the first area. As a result, the door management server 50 can manage the entrance of the user to the second area as well as the entrance to the first area.

Although the door management server 50 receives signals from the beacon management server 30 and the human sensor management server 40 here, the door management server 50 is communicably connected to the beacon receiver 10 and the human sensor 20. , the beacon receiver 10 and the occupancy sensor 20 directly.

(Action and effect of embodiment)
The door management system 1 of this embodiment detects a person present near the door 70 by the human sensor 20 installed near the door 70 on the second area side. Further, the door management system 1 uses the beacon receiver 10 installed near the door 70 on the second area side to transmit radio waves (signals) transmitted from the mobile beacon 80 carried by the user near the door 70 . receive. The signal includes identification information for identifying the portable beacon 80 (identification information of the user carrying the portable beacon 80). The beacon receiver 10 also measures the signal strength of the received signal. The door management server 50 controls unlocking of the door 70 based on the detection result of the human sensor 20, user identification information included in the signal received by the beacon receiver 10, and the reception strength of the signal. The door management server 50 stores identification information of users who are permitted to enter the first area in the storage unit 53 in advance as permitted user identification information. When the user identification information included in the signal received by the beacon receiver 10 is included in the authorized user identification information stored in the storage unit 53, the door management server 50 allows the user to enter the first area. Judged as an authorized user. Further, when the signal received by the beacon receiver 10 is equal to or greater than the threshold, the door management server 50 determines that the user is about to enter the first area. Furthermore, the door management server 50 determines that the user is present near the door 70 when the human sensor 20 detects a person near the door 70 . The door management server 50 determines that the signal received by the beacon receiver 10 is equal to or greater than the threshold, the identification information of the user included in the received signal is included in the authorized user identification information, and the motion sensor 20 is located near the door 70. When a person is detected in the door 70, the unlocking of the door 70 is instructed. As a result, it is possible to quickly unlock the door 70 for the user permitted to enter the first area while maintaining security. Further, the door management server 50 associates the identification information of the user with the time when the door 70 is unlocked and stores them in the storage unit 53 . The administrator of the first area can check the unlocking history indicating which user entered the first area and when, based on the information stored in the storage unit 53 . When the signal received by the beacon receiver 10 is used to control the unlocking of the door 70 without using the human sensor 20, it is used near the door 70 because the beacon receiver 10 has low detection accuracy of the user's position. The door 70 may be unlocked even when no one is present. Further, if the threshold value of the reception intensity is increased to improve security, the door 70 may not be unlocked when a user is present in the vicinity of the door 70 . Furthermore, when the beacon receiver 10 is not used and the human sensor 20 is used to control the unlocking of the door 70, the users permitted to enter the first area and the users who are not permitted to enter the first area It is difficult to distinguish between By combining the beacon receiver 10 and the human sensor 20 like the door management system 1 of the present embodiment, unlocking of the door 70 is suppressed when there is no user in the vicinity of the door 70. can do. Like the door management system 1 of this embodiment,
By combining the beacon receiver 10 and the human sensor 20, it is possible to appropriately unlock the door 70 while distinguishing users.

<Operation example of the modified example>
FIG. 9 is a diagram showing an example of the operation flow of the door management server 50 of the door management system 2 of the modification. Here, mainly the operations of parts different from the operation flow of FIG. 6 will be described. Here, it is assumed that the user who wants to enter the first area exists in the second area. It is assumed that users wearing portable beacons 80 and users not wearing portable beacons 80 can exist in the second area. It is assumed that the user wearing the portable beacon 80 wears the portable beacon 80 on the front side (chest side) of the body. Also, here, it is assumed that the door 70 is closed and locked by the unlocking device 60 . The mobile beacon 80 constantly (for example, every second) transmits a signal containing identification information for identifying the mobile beacon 80 . Also, assume that a user who is about to enter the first area turns his or her face to the second sensor 200 in advance to photograph the face (upper body) and measure the body temperature.

In S201, the controller 51 of the door management server 50 determines whether or not a signal from the second sensor 200 has been received. A second sensor 200 is installed in the second area. The second sensor 200 always captures an image of the surroundings of the second sensor 200 and detects a person (a person's face) based on known image recognition technology or the like. When the second sensor 200 detects a person (person's face), it measures the body temperature of the person. The second sensor 200 constantly detects the presence or absence of a person. The second sensor 200 transmits a captured image and a signal including the measurement result of the person's body temperature to the second sensor management server 210 . Here, it is assumed that the captured image includes an image of the detected human face. The signal may include time information indicating the date and time when the image was taken and the date and time when the person's body temperature was measured. The date and time when the image was taken and the date and time when the person's body temperature was measured are assumed to be the same, and the time information may be time information indicating one of the times. Upon receiving the signal from the second sensor 200 via the communication unit 212 , the control unit 211 of the second sensor management server 210 stores the image and the measurement result included in the received signal in the storage unit 213 . If the signal does not contain time information, the control unit 211 adds time information indicating the time when the signal was received, the date and time when the image was taken, and the date and time when the person's body temperature was measured, together with the image and the measurement result. It is stored in the storage unit 213 as time information to be displayed. The date and time when the image was captured and the date and time when the person's body temperature was measured are the dates and times when the second sensor 200 detected the person. The control unit 211 transmits a signal including the image, the measurement result, and the time information stored in the storage unit 213 to the door management server 50 via the communication unit 212 . The control unit 51 of the door management server 50 receives the signal from the second sensor management server 210 via the communication unit 52 . The signal is sent to the second sensor 200
is a signal from When the second sensor 200 does not detect a person (a person's face), it does not measure the body temperature of the person. In addition, when the second sensor 200 does not detect a person (a person's face), it does not transmit the captured image and the signal including the measurement result of the person's body temperature to the second sensor management server 210 . Therefore, when the second sensor 200 does not detect a person (person's face), the door management server 50 does not receive a signal from the second sensor 200 . If the signal from the second sensor 200 is received (S201; YES), the process proceeds to S202. If the signal from the second sensor 200 has not been received (S201; NO), the process proceeds to S203.

In S<b>202 , the control unit 51 stores the image, measurement result, and time information included in the received signal in the storage unit 53 .

In S203, the control unit 51 determines whether or not the human sensor 20 has detected the presence of a person. S203 is the same as S101 in FIG. The control unit 51 confirms whether or not the detection result of the received signal indicates presence of a person. If a person exists (S203; YES), the process proceeds to S204. If no person exists (no person exists) (S203: NO), the process returns to S201.

In S<b>204 , the control unit 51 determines whether or not a user permitted to enter the first area exists near the door 70 to enter the first area. S204 is the same as S102 in FIG. If it is determined that a user who is permitted to enter the first area exists near the door 70 to enter the first area (S204; YES), the process proceeds to S205. If it is determined that the user permitted to enter the first area does not exist near the door 70 trying to enter the first area (S204; NO), the process returns to S201.

In S205, the control unit 51 stores the image of the user's face associated with the identification information (permission identification information) for identifying the portable beacon 80 contained in the signal received in S204, stored in the storage unit 53; 2 It is determined whether or not the image of the face of the person included in the signal received from the sensor 200 is the image of the face of the same person. Known face recognition technology can be used to determine whether the person is the same person. Further, the control unit 51 determines whether the measurement result (human body temperature) included in the same signal received from the second sensor 200 is within a predetermined temperature range (for example, 35.0° C. or more and less than 37.5° C.). determine whether The predetermined temperature range is, for example, a temperature range indicating a person's body temperature (a person's normal body temperature). The control unit 51 determines that the identification information for identifying the mobile beacon 80 included in the signal received in S204 is permission identification information, and the image of the user's face associated with the permission identification information and the image captured by the second sensor 200 are detected. If the face image and the face image are of the same person, and the person's body temperature measured by the second sensor 200 is within a predetermined temperature range, the person detected in S203 is permitted to enter the first area. authenticate as a person In other cases, the person detected in S203 is regarded as a person permitted to enter the first area and is not authenticated. If authenticated (S205; YES), the process proceeds to S206. If not authenticated (S205; NO), the process returns to S201. The door management server 50 can more safely manage the user's entry into the first area by making determinations using more conditions.

Further, in S205, the control unit 51 may not authenticate when a predetermined time or more has passed since the time indicated by the time information included in the signal received from the second sensor 200. FIG. As a result, it is possible to refuse to enter the first area for a user who has passed a predetermined time or longer after being photographed and measured by the second sensor 200 . In addition, the control unit 51 periodically (for example, every day at 0:00 a.m.) stores information (human face image, measurement result (body temperature), time information) included in the signal received from the second sensor 200 from the storage unit 53 . ), it may be deleted. As a result, for example, if the user has not been imaged or measured by the second sensor 200 since midnight today, it is possible to refuse to enter the first area.

In S<b>206 , the control unit 51 of the door management server 50 instructs the unlocking device 60 via the communication unit 52 to unlock the door 70 . S206 is the same as S103 in FIG. Thereby, a user who is permitted to enter the first area can open the door 70 and enter the first area.

In S207, the controller 51 of the door management server 50 determines whether or not the human sensor 20 has detected the presence of a person. S207 is the same as S104 in FIG. The control unit 51 confirms whether or not the detection result of the received signal indicates presence of a person. If a person exists (S207; YES), the process of S207 is repeated. At this time, it is assumed that the user exists near the door 70 and the user has not yet passed through the opening between the first area and the second area. If no person exists (no person exists) (S207: NO), the process proceeds to S208. At this time, it is considered that the user who is permitted to enter the first area has entered the first area through the opening between the first area and the second area.

In S<b>208 , the control unit 51 of the door management server 50 instructs the unlocking device 60 via the communication unit 52 to lock the door 70 . S208 is the same as S105 in FIG.

In the operation flow described above, some processes may be omitted, or the order of the processes may be changed.

Although the door management server 50 receives signals from the beacon management server 30, the human sensor management server 40, and the second sensor management server 210 here, the door management server 50 includes the beacon receiver 10 and the human sensor 20. , may be communicatively connected to the second sensor 200 and receive signals directly from the beacon receiver 10, the human sensor 20, and the second sensor 200.

Second sensor 200 may not include a temperature sensor that measures the temperature of a person. Since the second sensor 200 does not include a temperature sensor, the configuration of the second sensor 200 can be simplified. Also, the second sensor 200 may include a sensor that detects biological information such as blood pressure, pulse, voiceprint, iris, vein, palm, fingerprint, weight, and height. The door management server 50 can permit a person with a specific condition (blood pressure, pulse rate, height, weight) to enter the first area. Further, the door management server 50 can permit entry into the first area based on biometric information such as veins and fingerprints in addition to the face. The control unit 51 of the door management server 50 determines whether or not the person is wearing a mask from the captured image of the person's face, and allows only the person wearing the mask to enter the first area. may be admitted. Well-known image recognition technology can be used to determine whether the mask is worn. Further, the control unit 51 of the door management server 50 may notify a person who does not wear a mask to wear a mask.
