The following embodiment can be variously modified according to the design or the like as long as the object of the present disclosure can be achieved.

(1) Overview The detection system 1 according to the present embodiment includes an information output system 10 and a receiver 20, as shown in FIGS. As shown in FIG. 2, the detection system 1 of the present embodiment includes a mobile communication terminal that exists in a first area A1 in a building 200 having a first area A1 and a second area A2 adjacent to the first area A1. 30 movement actions to the second region A2 are detected. In other words, the detection system 1 detects the movement action performed by the user 2 who carries the mobile communication terminal 30 in the first area A1. Here, the “moving action” is an action performed by the user 2 existing in the first area A1 to move to the second area A2. Examples of the moving behavior include an operation in which the user 2 approaches the entrance / exit to the second area A2 and an operation in which the user 2 faces the body at the entrance / exit to the second area A2.

Further, the second area A2 is an area having a higher security level than the first area A1. The building 200 is, for example, an office building having a plurality of second areas A2 for each floor (floor). The second area A2 includes, for example, an office room for offices, a room for conducting research, development, and manufacture of highly confidential products or research products, a library room, a fitness room, a laundry room, and the like as a whole, Or at least a part of the space. In the example of FIG. 2, the first area A1 is a passage in the building 200, and the second area A2 is a room facing the first area A1 (passage). That is, the information output system 10 according to the present embodiment performs the moving action that the user 2 carrying the mobile communication terminal 30 existing in the first area A1 (passage) moves to move to the second area A2 (room). To detect. 2, 5, and 9, the alternate long and short dash line in the figure indicates the movement locus of the mobile communication terminal 30 carried by the user 2, in other words, the movement locus of the user 2 carrying the mobile communication terminal 30.

(2) Configuration Hereinafter, configurations of the information output system 10 and the detection system 1 will be described with reference to FIGS.

The detection system 1 includes an information output system 10 and a receiver 20. In addition, the detection system 1 of the present embodiment further includes a mobile communication terminal 30.

In the present embodiment, as shown in FIGS. 1 to 3, the first area A1 is a passage, and the wall of the passage that is the first area A1 is provided with an automatic door DR1 that serves as an entrance of the second area A2. . In addition, a receiver 20 is installed above the automatic door DR1 on the wall of the passage that is the first region A1.

The detection system 1 of this embodiment mobile phone is used in combination with the entrance / exit management server 100. The entrance / exit management server 100 controls opening / closing of the automatic door DR1 based on the detection result of the detection system 1 and the like.

The receiver 20 is configured to perform wireless communication with the mobile communication terminal 30. The communication method of the receiver 20 is, for example, Bluetooth (registered trademark) Low Energy (BLE (registered trademark)). The receiver 20 transmits a radio signal (beacon signal) called an advertisement packet periodically (for example, every 0.1 second) toward the target region R1 in the first region A1.

Here, the “target area” R1 is at least a part of the first area A1, and is a space in which the receiver 20 and the mobile communication terminal 30 can communicate with each other. The receivers 20 are arranged so as to correspond to the target region R1 on a one-to-one basis. The target area R 1 is a space where a radio signal from the mobile communication terminal 30 reaches the receiver 20, for example. The receiver 20 has directivity characteristics adjusted by the shape and arrangement of the antenna and the shield member. The radio wave reception range of the receiver 20 is, for example, a half of a predetermined radius centered on the receiver 20 at the bottom surface. It is set in a conical space that forms a circle. Here, the predetermined radius means, for example, a distance at which the reception intensity of the radio signal received by the receiver 20 is equal to or greater than a predetermined first threshold value. For example, the first threshold value is set to a value corresponding to the reception intensity of the radio signal received by the receiver 20 from the mobile communication terminal 30 existing at a position about 3 m away from the receiver 20 on the floor surface. The communication method of the receiver 20 is not limited to BLE (registered trademark), and may be, for example, Wi-Fi (registered trademark), specific low power communication, or optical communication such as infrared communication or visible light communication. But you can. 1 to 3, the number of receivers 20 is one. However, a plurality of receivers 20 may be provided, and a plurality of receivers 20 are provided in a plurality of target regions R1 in the first region A1. It may be provided correspondingly.

The receiver 20 periodically transmits a radio signal to the target area R1. When the mobile communication terminal 30 existing in the target area R 1 receives a radio signal from the receiver 20, the mobile communication terminal 30 transmits a radio signal including identification information of the mobile communication terminal 30 to the receiver 20. Therefore, the receiver 20 receives a radio signal including identification information of the mobile communication terminal 30 from the mobile communication terminal 30 existing in the target region R1.

Based on the radio signal received from the mobile communication terminal 30, the receiver 20 generates notification information D 11 including information related to the reception intensity (RSSI: Received Signal Strength) of the radio signal. The receiver 20 transmits the notification information D11 to the information generation unit 13 of the information output system 10 by wireless communication using radio waves as a medium. More specifically, after receiving the radio signal from the mobile communication terminal 30, the receiver 20 receives the identification information of the mobile communication terminal 30, the receiver information of the receiver 20, and information about the reception strength of the radio signal. The notification information D11 that is included is transmitted to the information output system 10. Here, the receiver 20 holds receiver information that is an ID (Identification) assigned to each receiver 20 in a nonvolatile memory or the like included in the receiver 20.

The mobile communication terminal 30 is carried by the user 2 who uses the building 200. The mobile communication terminal 30 is a communication terminal such as a smartphone. Individual identification information is assigned to the mobile communication terminal 30, and the identification information is held in a nonvolatile memory or the like of the mobile communication terminal 30. When a plurality of users 2 use the building 200, the plurality of users 2 use (carry) individual mobile communication terminals 30. That is, since the mobile communication terminal 30 and the user 2 correspond one-to-one and the identification information of the mobile communication terminal 30 is associated with the user 2, the mobile communication carried by the user 2 for each user 2. The identification information of the terminal 30 is different. The mobile communication terminal 30 is installed with application software (application) that transmits a response signal including identification information of the mobile communication terminal 30 to the receiver 20 when a beacon signal transmitted from the receiver 20 is received. When the mobile communication terminal 30 exists in the target area R1, when the mobile communication terminal 30 existing in the target area R1 receives a radio signal (beacon signal) transmitted from the receiver 20, the mobile communication terminal 30 includes identification information. A radio signal (beacon response) is transmitted to the receiver 20.

As shown in FIG. 1, the information output system 10 is realized by a server including a communication unit 11, a storage unit 12, an information generation unit 13, and a processing unit (output unit, determination unit) 14. The information output system 10 is mainly composed of, for example, a computer system (including a microcomputer) including a processor and a memory. That is, the computer system functions as the information output system 10 by executing an appropriate program on the processor.

The communication unit 11 performs wireless communication with the receiver 20. When the communication unit 11 receives the notification information D11 (identification information of the mobile communication terminal 30, the reception strength of the radio signal from the mobile communication terminal 30 and the receiver information of the receiver 20) transmitted from the receiver 20, the communication unit 11 receives the notification information D11. The notification information D11 is output to the information generation unit 13.

The storage unit 12 includes, for example, a rewritable nonvolatile memory such as an EEPROM (ElectricallyrErasable Programmable Read-Only Memory). The storage unit 12 stores receiver information of the receiver 20 and position information indicating an installation position of the receiver 20.

In the present embodiment, the receiver 20 is provided corresponding to the automatic door DR1 serving as an entrance from the first area A1 to the second area A2. The storage unit 12 stores identification information of the mobile communication terminal 30 that is permitted to enter the second area A2 and receiver information of the receiver 20 corresponding to the second area A2.

The information generation unit 13 receives notification information D11 including identification information of the mobile communication terminal 30, receiver information of the receiver 20, and information on reception intensity from the communication unit 11. The information generation unit 13 generates first information related to the position of the mobile communication terminal 30 in the first area A1 based on the receiver information and the information related to the reception intensity.

The information generation unit 13 statistically processes the reception strength of the radio signal that the communication unit 11 periodically receives (for example, every 0.1 second), and based on the reception strength after the statistical processing, Output first information about the position. When the receiver 20 receives a radio signal from the mobile communication terminal 30, the radio signal reaches the receiver 20 through various paths (multipath), and thus a phase difference occurs between the direct wave and the reflected wave, Interference between the direct wave and the reflected wave occurs. When the communication method is BLE (registered trademark), if the distance between the receiver 20 and the portable communication terminal 30 is about 0.5 m or less in a plane parallel to the floor surface, the reception intensity of the direct wave is reflected wave. It is sufficiently larger than the reception strength. For this reason, fluctuations in reception intensity caused by interference between the direct wave and the reflected wave are reduced, and the reception intensity decreases in proportion to the distance between the receiver 20 and the mobile communication terminal 30 in a plane parallel to the floor surface. . On the other hand, when the distance between the receiver 20 and the portable communication terminal 30 exceeds about 0.5 m in a plane parallel to the floor surface, the direct wave reception intensity is reduced, which causes interference between the direct wave and the reflected wave. The influence of fluctuations in reception strength becomes relatively large. Therefore, the relationship between the distance between the receiver 20 and the portable communication terminal 30 and the reception intensity in a plane parallel to the floor surface does not become linear.

Therefore, the information generation unit 13 statistically processes the reception strength of the radio signal that the communication unit 11 periodically receives from the receiver 20. For example, the information generation unit 13 compares the received intensity data received by the communication unit 11 in the past predetermined period (for example, a period from 3 seconds before to the present) with the first threshold value and the second threshold value, respectively. The first threshold is a reception intensity of a radio signal received by the receiver 20 from the mobile communication terminal 30 located at a position away from the receiver 20 by a first distance (for example, 3 m). The second threshold is a reception intensity of a radio signal received by the receiver 20 from the mobile communication terminal 30 located at a position away from the receiver 20 by a second distance (for example, 0.5 m). Here, the area where the distance from the receiver 20 is equal to or less than the first distance is the target area R1 set in the first area A1, and the area where the distance from the receiver 20 is equal to or less than the second distance is the target area. This is the stop region R12 set in R1 (see FIG. 2). In addition, a region outside the stop region R12 in the target region R1 is referred to as a peripheral region R11.

The information generation unit 13 determines that the mobile communication terminal 30 exists in the external region R2 outside the target region R1 in the first region A1 if the reception intensity is smaller than the first threshold. The information generation unit 13 determines that the mobile communication terminal 30 exists in the peripheral region R11 if the reception intensity is equal to or higher than the first threshold value and smaller than the second threshold value. Further, the information generation unit 13 determines that the mobile communication terminal 30 exists in the stop region R12 if the reception intensity is equal to or greater than the second threshold value.

The information generation unit 13 determines the position where the mobile communication terminal 30 exists every time reception intensity is input from the communication unit 11 (every 0.1 second). In the past predetermined period (for example, the past 3 seconds), the information generation unit 13 selects an area having the largest number of times that the mobile communication terminal 30 is determined to exist among the peripheral area R11, the stop area R12, and the external area R2. It is determined that the mobile communication terminal 30 is presently present. Then, the information generation unit 13 outputs the information of the area determined that the mobile communication terminal 30 currently exists to the processing unit 14 as the first information D1 regarding the position of the mobile communication terminal 30.

In addition, the method by which the information generation unit 13 obtains the first information D1 is not limited to the above method, and other methods may be used. For example, the information generation unit 13 performs statistical processing on the received intensity data received by the communication unit 11 during a past predetermined period (for example, the past 3 seconds), and obtains the average value of the received intensity and the variance σ2. The information generation unit 13 excludes data whose difference from the average value is larger than 2σ (or 3σ) from the received intensity data in the past predetermined period, and then calculates the average value again. And the information generation part 13 will judge that the mobile communication terminal 30 exists in the external area | region R2 outside the object area | region R1 in 1st area | region A1, if the average value of receiving intensity is smaller than a 1st threshold value. The information generation unit 13 determines that the mobile communication terminal 30 exists in the peripheral region R11 if the average value of the reception intensity is equal to or greater than the first threshold value and smaller than the second threshold value. Further, the information generation unit 13 determines that the mobile communication terminal 30 exists in the stop region R12 if the average value of the reception intensity is equal to or greater than the second threshold value.

As described above, the information generation unit 13 statistically analyzes the reception intensity data periodically input from the communication unit 11 to obtain the first information D1 regarding the position of the mobile communication terminal 30 in the first region A1. Since it is generated, the first information D1 can be obtained with high accuracy. Moreover, since the information generation part 13 is calculating | requiring the 1st information D1 by processing statistically the data of the receiving intensity of the past predetermined period (for example, 3 seconds), the portable communication terminal 30 of the predetermined period First information about the position can be determined. The period during which the information generation unit 13 statistically processes the received intensity data is not limited to 3 seconds, and can be changed as appropriate.

The processing unit 14 (output unit) outputs second information D2 related to the movement behavior of the mobile communication terminal 30 from the first area A1 to the second area A2 based on the first information D1 input from the information generation unit 13. To do.

For example, the processing unit 14 determines that the mobile communication terminal 30 existing in the peripheral area R11 has moved to the stop area R12 based on the first information D1 and has stopped in the stop area R12 for a predetermined stop time or longer. Then, it is determined that the user 2 has performed a moving action for moving to the second area A2. That is, when the first information D1 includes information regarding the movement of the mobile communication terminal 30 in the first area A1 in the direction approaching the second area A2, the processing unit 14 indicates that the user 2 is in the second area A2. It is determined that a moving action for moving to is performed.

In addition, the processing unit 14 (determination unit), based on the identification information and the receiver information of the mobile communication terminal 30 received by the communication unit 11, the mobile communication terminal 30 (that is, the user) stopped in the stop region R12. 2) determines whether or not entry into the second area A2 is permitted.

The processing unit 14 performs a moving action for the user 2 of the mobile communication terminal 30 existing in the stop area R12 to move to the second area A2, and permits the mobile communication terminal 30 to enter the second area A2. When it is determined that the automatic door DR1 is opened, the information for opening the automatic door DR1 is output to the entrance / exit management server 100 as the second information D2. In addition, when the processing unit 14 determines that the user 2 of the mobile communication terminal 30 existing in the stop area R12 performs a moving action and the mobile communication terminal 30 is not permitted to enter the second area A2, Information for closing the automatic door DR1 is output to the entrance / exit management server 100 as the second information D2.

The entrance / exit management server 100 is configured to open-control the automatic door DR1 based on the second information D2 (information for opening the automatic door DR1) output from the information output system 10 of the detection system 1. . More specifically, when information for opening the automatic door DR1 (second information D2) is input from the information output system 10, the entrance / exit management server 100 communicates with the drive unit 101 that drives the automatic door DR1. To control the opening and closing of the automatic door DR1. The entrance / exit management server 100 communicates with the drive unit 101 that opens and closes the automatic door DR1 by wired communication or wireless communication. The entrance / exit management server 100 generates a control signal for the drive unit 101 based on the information (second information D2) for opening the automatic door DR1 output by the information output system 10, and outputs the control signal to the drive unit 101. By doing so, the opening and closing of the automatic door DR1 is controlled. In addition, it is not limited to what the automatic door DR1 is installed in the entrance / exit of 2nd area | region A2, The electric lock is provided in the entrance / exit of 2nd area | region A2, and the entrance / exit management server 100 output the information output system 10 The electric lock may be unlocked based on information for opening the electric lock.

In addition, if the processing unit 14 determines that the mobile communication terminal 30 that has performed the moving action to the second area A2 is not permitted to enter the second area A2, information for outputting an alarm is displayed as the second information. D2 may be output, and the entrance / exit management server 100 may issue a warning by sound, light, or the like.

(3) Operation The operation of the detection system 1 of the present embodiment will be described with reference to FIGS.

As shown in FIG. 1, the user 2 in the first area A1 is moving from the outside of the target area R1 (the right side in FIG. 1) toward the automatic door DR1 in order to enter the second area A2. The case will be described. The user 2 carries the mobile communication terminal 30 and hangs the mobile communication terminal 30 from the neck with a strap or the like, for example.

Hereinafter, the operation of the detection system 1 will be described based on the flowchart of FIG. The receiver 20 transmits a radio signal (beacon signal) to a region including the target region R1 in the first region A1 every time a predetermined transmission cycle (for example, 0.1 second) elapses (S1: Yes) (S2 ).

While the user 2 is in the external area R2, the mobile communication terminal 30 carried by the user 2 cannot receive the radio signal (beacon signal) transmitted from the receiver 20, but receives from the mobile communication terminal 30. No radio signal is transmitted to the machine 20. In this case, the information generation unit 13 determines that the mobile communication terminal 30 does not exist in the target area R1 (S3: No), and returns to the process of S1. Although the mobile communication terminal 30 may be able to receive a radio signal from the receiver 20 even while the user 2 is in the external region R2, the reception strength of the radio signal transmitted from the mobile communication terminal 30 is the first. It becomes lower than 1 threshold value. Also in this case, the information generation unit 13 determines that the mobile communication terminal 30 does not exist in the target area R1 (S3: No), and returns to the process of S1.

Thereafter, when the user 2 enters the target area R1 from the external area R2, the mobile communication terminal 30 carried by the user 2 receives a radio signal (beacon signal) transmitted from the receiver 20, and performs mobile communication. A radio signal including identification information of the terminal 30 is transmitted to the receiver 20.

When the receiver 20 receives the radio signal from the mobile communication terminal 30 (S3: Yes), the notification information D11 including the identification information of the mobile communication terminal 30, the reception intensity of the radio signal, and the receiver information is sent to the information output system 10. Output.

In the information output system 10, when the communication unit 11 receives the notification information D 11 from the receiver 20, it outputs the received notification information D 11 to the information generation unit 13.

The information generation unit 13 generates the first information D1 related to the position of the mobile communication terminal 30 in the first area A1 based on the reception intensity included in the notification information D11. The information generation unit 13 determines that the mobile communication terminal 30 exists in the peripheral region R11 outside the stop region R12 in the target region R1 if the reception intensity is equal to or higher than the first threshold value and smaller than the second threshold value. The information generation unit 13 determines that the mobile communication terminal 30 exists in the stop region R12 if the reception intensity is equal to or greater than the second threshold value. The information generation unit 13 determines the position where the mobile communication terminal 30 exists every time reception intensity is input from the communication unit 11 (every 0.1 second), and associates the determination result with the time information to store the storage unit 12. Remember me. Based on the determination result of the past predetermined period stored in the storage unit 12, the information generation unit 13 includes the mobile communication terminal among the peripheral region R11, the stop region R12, and the external region R2 in the past predetermined period. The region having the largest number of times that it is determined that 30 is present is determined as the region where the mobile communication terminal 30 currently exists. And the information generation part 13 outputs the information of the area | region judged that the mobile communication terminal 30 exists now to the process part 14 as 1st information D1 (S4).

Next, based on the first information D1 input from the information generation unit 13, the processing unit 14 causes the user 2 carrying the mobile communication terminal 30 to move from the first area A1 to the second area A2. It is determined whether or not a moving action is being performed. For example, after the mobile communication terminal 30 existing in the peripheral area R11 has moved to the stop area R12 based on the first information D1, the processing unit 14 performs a predetermined stop time (for example, 1 to 3 seconds) in the stop area R12. If it is determined that the mobile communication terminal 30 is moving to the second area A2 (S5: Yes). When the processing unit 14 determines that the user 2 is not moving to the second area A2 (S5: No), the processing unit 14 returns to the process of S1.

When the processing unit 14 determines that the user 2 of the mobile communication terminal 30 is moving, the processing unit 14 uses the mobile communication terminal 30 identification information and the receiver information received by the communication unit 11. 30 (User 2) determines whether or not entry to the second area A2 is permitted (S6). That is, the processing unit 14 authenticates the mobile communication terminal 30 (user 2).

When the processing unit 14 determines that the mobile communication terminal 30 (that is, the user 2) existing in the stop area R12 is permitted to enter the second area A2 (S6: Yes), the processing unit 14 determines Information for opening the automatic door DR1 is output as the two information D2 (S7). When the processing unit 14 determines that the mobile communication terminal 30 (that is, the user 2) existing in the stop area R12 is not permitted to enter the second area A2 (S6: No), the processing unit 14 sends a request to the entrance / exit management server 100. 2 The process is terminated without outputting the information D2.

On the other hand, when information for opening the automatic door DR1 is input from the processing unit 14 as the second information D2, the entrance / exit management server 100 outputs a control signal for opening the automatic door DR1 to the drive unit 101 to drive it. Part 101 opens automatic door DR1. Thereby, the user 2 does not need to perform a special operation to open the automatic door DR1, and can enter the second area A2 in a hands-free manner, so that there is an advantage that convenience is improved.

When the automatic door DR1 opens and the user 2 who has been in the stop area R12 moves to the second area A2, the receiver 20 cannot receive a radio signal from the mobile communication terminal 30 carried by the user 2. When the state in which the communication unit 11 cannot receive the notification information D11 from the receiver 20 elapses for a certain period of time, the information generation unit 13 indicates that the mobile communication terminal 30 (that is, the user 2 carrying the mobile communication terminal 30) is in the target area R1. Judge that it does not exist. The information generation unit 13 outputs first information D1 indicating that the mobile communication terminal 30 does not exist in the target region R1, and the processing unit 14 performs entry / exit management using the information for closing the automatic door DR1 as second information D2. Output to the server 100.

When information for closing the automatic door DR1 is input as the second information D2 from the processing unit 14 to the entrance / exit management server 100, the entrance / exit management server 100 outputs a control signal for closing the automatic door DR1 to the drive unit 101. Closes the automatic door DR1.

The entrance / exit management server 100 outputs a control signal for closing the automatic door DR1 after a predetermined time (for example, several seconds) has elapsed after outputting the control signal for opening the automatic door DR1 to the drive unit 101. It may be output.

As described above, the detection system 1 outputs the information for opening the automatic door DR1 to the entrance / exit management server 100, so that only the user 2 who is qualified to enter the second area A2 enters the second area A2. And the security level of the second area A2 is maintained.

In the method of downloading the program, the information output system 10 only needs to have a communication function for communicating with an external device using a network.

Further, the receiver 20 only needs to be arranged at a position where it can communicate with the mobile communication terminal 30 and may not be installed in the vicinity of the automatic door DR1, which is an entrance / exit, so that the installation position of the receiver 20 can be freely set. The degree becomes higher. In addition, when there are a plurality of entrances and exits, it is sufficient that a plurality of receivers are arranged corresponding to a plurality of stop areas provided in front of the plurality of entrances and exits, and the degree of freedom of arrangement of the receivers is high. There are advantages.

(4.1) Modification 1
In the information output system 10 of the above embodiment, the information generation unit 13 determines whether the mobile communication terminal 30 exists in the peripheral region R11 or the stop region R12 based on the reception strength of the radio signal received by the communication unit 11. However, the distance to the mobile communication terminal 30 may be obtained based on the reception intensity.

The information generation unit 13 performs a statistical process on the reception strength of the radio signal received by the communication unit 11 to obtain the current reception strength (for example, average value). Then, the information generation unit 13 estimates the distance from the receiver 20 to the mobile communication terminal 30 based on the current reception strength, and displays information indicating the estimated value of the distance from the receiver 20 to the mobile communication terminal 30. One piece of information may be output to the processing unit 14. Based on the first information input from the information generation unit 13, the processing unit 14 can estimate an area (peripheral area R 11 or stop area R 12) where the mobile communication terminal 30 exists. Further, the processing unit 14 can estimate the moving speed of the mobile communication terminal 30 based on a change in the distance from the receiver 20 to the mobile communication terminal 30. In this case, when the processing unit 14 detects that the mobile communication terminal 30 has stopped in the stop region R12 after moving in the peripheral region R11 at a speed equal to or higher than the predetermined speed, the user 2 of the mobile communication terminal 30 performs the second operation. It is determined that the moving action for moving to the area A2 has been performed, and the second information is output.

In the information output system 10 of the above embodiment, when the plurality of receivers 20 are provided in the first area A1, the information generation unit 13 uses a plurality of receivers 20 based on the reception strength. The distance from the receiver 20 to the mobile communication terminal 30 can be estimated. Here, if the location information regarding the installation positions of the plurality of receivers 20 is stored in the storage unit 12, the information generation unit 13 determines the distance from the plurality of receivers 20 to the mobile communication terminal 30, and the plurality of receivers. The position coordinates of the mobile communication terminal 30 can be obtained based on the 20 installation positions. Specifically, the information generation unit 13 can obtain the position coordinates (for example, two-dimensional coordinates on the floor surface) of the mobile communication terminal 30 in the first area A1. Based on the position coordinates of the mobile communication terminal 30 and the position information of the peripheral area R11, the stop area R12, the automatic door DR1, etc., the information generation unit 13 detects that the mobile communication terminal 30 that has moved the peripheral area R11 is the stop area. It is possible to generate the first information D1 indicating that it has stopped at R12. The information generation unit 13 calculates the three-dimensional coordinates of the mobile communication terminal 30 in the first region A1 based on the distances from the plurality of receivers 20 to the mobile communication terminals 30 and the installation positions of the plurality of receivers 20. You may ask for it. Thereby, when the mobile communication terminal 30 is mounted on a flying object such as an unmanned airplane or airship called a drone, the position of the flying object in the air can be obtained.

Moreover, the information generation part 13 can obtain | require the movement locus | trajectory of the portable communication terminal 30 from the time series data of the position coordinate of the portable communication terminal 30, and produces | generates the information D1 containing the information regarding the movement locus | trajectory of the portable communication terminal 30. You can also. In this case, the processing unit 14 can detect whether or not the user 2 is performing a movement action based on the information of the movement locus included in the first information D1. For example, when a plurality of checkpoints are set in the first area A1 and the mobile communication terminal 30 moves to the stop area R12 through the plurality of checkpoints, the processing unit 14 determines that the user 2 has performed a moving action. May judge. Thereby, when the mobile communication terminal 30 moves to the stop region R12 without passing through one or more checkpoints among the plurality of checkpoints, the processing unit 14 determines that the user 2 is not moving. Therefore, there is an advantage that security performance is improved.

(4.2) Modification 2
In the information output system 10 according to the embodiment and the first modification, there is one receiver 20, but a plurality of receivers 20 may be arranged.

As shown in FIG. 5, in the first area A1, a receiver 21 is installed on the upper wall of the automatic door DR1 serving as an entrance of the second area A2. Two

receivers

22 and 23 are arranged on the ceiling of the first area A1 along the moving direction X1 in which the user 2 moves in the first area A1. The two

receivers

22 and 23 are arranged so that the automatic door DR1 is located in the middle of the

receivers

22 and 23 in the movement direction X1. The storage unit 12 of the information output system 10 stores receiver information of the

receivers

21, 22 and 23 and position information indicating the installation positions of the

receivers

21, 22 and 23.

Here, the receiver 21 is attached to the horizontal wall of the first area A1 that is a corridor, and the directivity is adjusted by the shape and arrangement of the antenna and the shield member. In the example of FIG. 5, the directivity of the receiver 21 is limited in the longitudinal direction (movement direction X1) of the first area A1, so that the mobile communication terminal 30 existing in front of the automatic door DR1 can be detected. The directivity of the receiver 21 is adjusted. The

receivers

21, 22, and 23 have the same configuration as the receiver 20 described in the above-described embodiment. When the

individual receivers

21, 22, and 23 are described without being specified, they are described as the receiver 20. To do.

The

receivers

21, 22, and 23 each wirelessly transmit a radio signal (beacon signal) at a predetermined cycle (for example, 0.1 second cycle). When the mobile communication terminal 30 existing in the first area A1 receives the radio signal from the

receivers

21, 22, and 23, the mobile communication terminal 30 transmits a radio signal including identification information of the mobile communication terminal 30. When the

receivers

21, 22, 23 receive the wireless signal transmitted from the mobile communication terminal 30 after transmitting the wireless signal, the identification information of the mobile communication terminal 30, the reception strength of the wireless signal, and the receiver information of the receiver Is output to the information output system 10.

In the information output system 10, when the communication unit 11 receives the notification information D11 from the

receivers

21, 22, and 23, the received notification information D11 is output to the information generation unit 13.

The information generation unit 13 generates first information D1 related to the position of the mobile communication terminal 30 in the first area A1 based on the notification information D11 from the

receivers

21, 22, and 23 received by the communication unit 11.

FIG. 6 shows temporal changes in the reception strengths B1, B2, and B3 of the radio signals received by the

receivers

21, 22, and 23 from the mobile communication terminal 30, respectively. The user 2 carrying the mobile communication terminal 30 is moving the first area A1, which is a corridor, from the position farther than the receiver 23 relative to the automatic door DR1 toward the automatic door DR1. The mobile communication terminal 30 is hung from the neck of the user 2 using, for example, a neck strap, and is located on the front side of the user 2 in the movement direction X1 while the user 2 is moving (walking). . At time t1 in FIG. 6, the user 2 passes under the receiver 23, at time t2, the user 2 stops in front of the automatic door DR1 (that is, the receiver 21), and at time t3, the user 2 has the automatic door. The body is turned to face DR1.

The reception intensity B3 of the radio signal at the receiver 23 increases as the user 2 carrying the mobile communication terminal 30 approaches the receiver 23, and becomes the maximum when the user 2 passes under the receiver 23 (around time t1). Thereafter, it gradually decreases as it approaches the automatic door DR1. The mobile communication terminal 30 is located on the front side of the body of the user 2, and when the user 2 passes under the receiver 23, the body of the user 2 is positioned between the mobile communication terminal 30 and the receiver 23. Will do. The 2.4 GHz band radio wave used in BLE (registered trademark) is easily absorbed by moisture, and the radio signal transmitted from the mobile communication terminal 30 is absorbed by the body of the user 2. The signal reception strength B3 is greatly reduced. Further, if the body 2 is turned so that the user 2 faces the automatic door DR1 from the state where the user 2 stops in front of the automatic door DR1, the shielding effect of the radio signal by the body of the user 2 is reduced. The reception intensity B3 of the radio signal is increased.

The reception intensity B2 of the wireless signal at the receiver 22 increases as the user 2 carrying the mobile communication terminal 30 approaches the automatic door DR1 after passing under the receiver 23, and stops before the automatic door DR1. Around (maximum time t2). Thereafter, when the user 2 changes the direction so as to face the automatic door DR1 in front of the automatic door DR1, the relative angle between the receiver 22 and the mobile communication terminal 30 changes. The reception intensity B2 of the radio signal at the receiver 22 decreases due to the directivity.

Further, the reception intensity B1 of the radio signal at the receiver 21 gradually increases when the user 2 carrying the mobile communication terminal 30 moves close to the automatic door DR1 (around time t2). At this time, since the user 2 faces the receiver 23 in the moving direction X1, the reception intensity B1 at the receiver 21 is smaller than the reception intensity B2 at the receiver 22. Thereafter, when the user 2 changes the body direction so as to face the automatic door DR1, the reception intensity B1 at the receiver 21 increases and the reception intensity B2 at the receiver 22 decreases.

As described above, the reception strengths B1, B2, and B3 of the radio signals at the three

receivers

21, 22, and 23 change as the user 2 carrying the mobile communication terminal 30 moves. Therefore, the information generation unit 13 determines whether or not the user 2 carrying the mobile communication terminal 30 is performing a moving action for moving to the second area A2 based on the relationship between the reception strengths B1, B2, and B3. it can.

For example, the information generation unit 13 uses the learned model based on the current reception strengths B1, B2, and B3 input from the communication unit 11, and allows the user 2 carrying the mobile communication terminal 30 to use the automatic door DR1. It is determined whether or not it is directly facing. When the received intensities B1, B2, and B3 are in a relationship surrounded by the frame W1 in FIG. 6, the information generating unit 13 indicates that the user 2 of the mobile communication terminal 30 existing in the first area A1 is correctly connected to the automatic door DR1. It judges that it is corresponding, and produces | generates the 1st information D1. At this time, the processing unit 14 determines that the user 2 of the mobile communication terminal 30 is moving to the second area A2 based on the first information D1 input from the information generation unit 13. And the process part 14 should just output the 2nd information D2 regarding the movement action to 2nd area | region A2 to the entrance / exit management server 100. FIG.

The learned model used by the information generation unit 13 is a stochastic gradient descent method, a support vector machine (SVM) based on the history of the reception strengths B1, B2, and B3 of the

receivers

21, 22, and 23. Generated by a machine learning algorithm. Here, if the machine learning is performed based on the received intensities B1, B2, and B3 when the user 2 performs the moving action for moving to the second area A2, the recognition rate using the learned model is improved. Can be made.

For example, a system that controls the opening and closing of the automatic door DR1 may include a voice detection unit that detects a predetermined command word spoken by the user 2 to open the automatic door DR1. In this case, since the entrance / exit management server 100 performs control to open the automatic door DR1 based on the detection result of the voice detection unit, the reception strengths B1, B2, and B3 when the voice detection unit detects a predetermined command word are determined. If machine learning is originally performed, the recognition rate using the learned model can be improved.

Further, the system that controls the opening and closing of the automatic door DR1 may include a card reader that performs non-contact communication with the IC card possessed by the user 2. In this case, the entrance / exit management server 100 performs control to open the automatic door DR1 when the identification information read from the IC card by the card reader matches the predetermined identification information. Therefore, if machine learning is performed based on the received intensities B1, B2, and B3 when the identification information read from the IC card by the card reader matches the predetermined identification information, the recognition rate using the learned model is improved. be able to.

Here, in the case where the building 200 is a building such as a high-rise apartment that has a common floor plan on a plurality of floors, the learned model created on the reference floor is represented by the first area A1, the second area A2, and The present invention can also be applied to other floors where the arrangement of the receivers 20 is similar. Therefore, the information generation unit 13 can improve the recognition rate using the learned model by using a learned model with a high recognition rate created on the reference floor or the like.

In the second modification, the information generation unit 13 may generate the first information based on a relationship of values (relative values) obtained by dividing the reception intensities B1, B2, and B3 by the reception intensities of specific receivers. Good. Thereby, even when the reception intensities B1, B2, and B3 are reduced due to the mobile communication terminal 30 being in the bag, the first information D1 can be generated more accurately.

Moreover, in the modification 2, the information generation part 13 makes the user 2 carrying the portable communication terminal 30 automatic door DR1 based on the temporal change pattern of reception intensity | strength B1, B2, B3 which the communication part 11 received. It may be determined whether or not it is directly facing. As shown in FIG. 7, when the reception intensities B1, B2, and B3 change, the information generation unit 13 captures the reception intensities B1, B2, and B3 at a predetermined time interval (for example, 0.5 second interval), for example. Based on the received intensities B1, B2, and B3 for the most recent predetermined number of times (for example, four times surrounded by the frames W11 to W14), the information generation unit 13 uses the learned model to make the user 2 use the automatic door DR1. It is determined that the body has been turned toward the automatic door DR1.

As described above, the information generation unit 13 determines whether the user 2 is facing the automatic door DR1 based on the temporal change pattern of the reception strengths B1, B2, and B3. Compared with the case where the determination is made only from B1, B2, and B3, the determination can be made with higher accuracy.

In Modification 3, it is determined that the user 2 has changed the direction of the body toward the automatic door DR1 based on the reception strengths B1, B2, and B3, but the gyro sensor provided in the mobile communication terminal 30 or You may detect that the user 2 changed the direction of the body based on the measured value of the acceleration sensor. When receiving a response to the beacon signal from the mobile communication terminal 30, the receiver 20 requests the mobile communication terminal 30 for a measurement value of a gyro sensor or an acceleration sensor included in the mobile communication terminal 30. Then, when receiving the measurement value of the gyro sensor or the acceleration sensor from the mobile communication terminal 30, the receiver 20 outputs the received measurement value to the communication unit 11. Thereby, the information generation part 13 can detect reliably that the portable communication terminal 30 changed direction based on the measured value of a gyro sensor or an acceleration sensor, and contains the information that the portable communication terminal 30 changed direction. The first information D1 can be output to the processing unit 14.

(4.3) Modification 3
In the embodiment and the first and second modifications, the information output system 10 may further include an acquisition unit (communication unit 11) that acquires the third information D3 related to the detection result of the detection unit 40 (see FIG. 8). The detection unit 40 detects the presence or absence of a person in a detection region R13 (see FIG. 9) set in front of the automatic door DR1 that is an entrance to the second region A2 in the first region A1. The detection region R13 is a region narrower than the stop region R12, and is a region immediately in front of the automatic door DR1.

The detection unit 40 includes, for example, a pressure sensor provided on the floor of the first region A1, and a communication module that performs wireless communication with the communication unit 11 of the information output system 10. The detection unit 40 detects whether a person is present in the detection region R13 based on the detection value of the pressure sensor. Specifically, when the detection value of the pressure sensor exceeds a predetermined threshold value, the detection unit 40 outputs third information D3 indicating that a person is present in the detection region R13, and the detection value of the pressure sensor is less than the threshold value. If so, the third information D3 indicating that no person is present in the stop region R12 is output.

The communication unit 11 serving as an acquisition unit acquires the third information D3 from the detection unit 40 by performing wireless communication with the detection unit 40. When the communication unit 11 acquires the third information D3, the communication unit 11 outputs the third information D3 to the processing unit 14. Here, the communication unit 11 may periodically communicate with the detection unit 40 to acquire the third information D3 from the detection unit 40, or the presence of a person when the detection unit 40 detects the presence of a person. May be output to the communication unit 11.

The processing unit 14 outputs the second information D2 based on the first information D1 input from the information generation unit 13 and the third information D3 input from the communication unit 11. When the first information D1 indicating that the mobile communication terminal 30 has moved to the stop region R12 is input and the third information D3 indicating that there is a person in the detection region R13 is input to the processing unit 14, The second information D2 related to the movement behavior of the mobile communication terminal 30 from the first area A1 to the second area A2 is output. For example, the processing unit 14 outputs information for opening the automatic door DR1 to the entrance / exit management server 100 as the second information D2.

When the information for opening the automatic door DR1 is input as the second information D2 from the processing unit 14 to the entry / exit management server 100, the entry / exit management server 100 outputs a control signal for opening the automatic door DR1 to the drive unit 101. Opens the automatic door DR1.

Thus, since the processing unit 14 outputs the second information D2 based on the first information D1 and the third information D3 related to the detection result of the detection unit 40, the movement behavior of the mobile communication terminal 30 is reliably detected. it can.

In the third modification, the detection unit 40 may include a load sensor that can detect a load distribution on the detection surface. In this case, the detection unit 40 can detect a change in the position on which the load is applied based on the detection value of the load sensor, and the communication unit 11 uses the presence / absence of the load and the information on the position on which the load is applied as the third information D3. Output to. The processing unit 14 receives the first information D1 indicating that the mobile communication terminal 30 has moved to the stop region R12, and the third information D3 that the position of the load is moving toward the automatic door DR1. Is input, it is determined that the user 2 is moving to the second area A2. The processing unit 14 outputs the second information D2 related to the movement behavior of the mobile communication terminal 30 from the first area A1 to the second area A2 to the entrance / exit management server 100, and the entrance / exit management server 100 is based on the second information D2. Control to open the automatic door DR1. As described above, when the detection unit 40 includes a load sensor that can detect the distribution of the load on the detection surface, it is used based on the movement of the position where the load is applied, that is, the movement locus of the user 2. It can be determined whether the person 2 is moving.

In the third modification, the entrance / exit of the second area A2 (automatic door DR1) is one, but there may be a plurality of entrances / exits to the second area A2. For example, as shown in FIG. 10, when there are a plurality (for example, three places) of gates G1 to G3 serving as entrances to the second region A2, the detection regions R131, R132, and R133 in front of the gates G1, G2, and G3

Corresponding detection units

41, 42, and 43 are sufficient.

Since the

detection units

41, 42, and 43 have the same configuration, the detection unit 41 will be described, and description of the

detection units

42 and 43 will be omitted. The detection unit 41 includes a pressure sensor provided on the floor in front of the gate G1. The detection unit 41 detects the presence or absence of a person in the detection region R131 based on the detection value of the pressure sensor. Specifically, when the detection value of the pressure sensor exceeds a predetermined threshold value, the detection unit 41 outputs third information D3 indicating that a person is present in the detection region R131, and the detection value of the pressure sensor is less than the threshold value. If so, the third information D3 indicating that no person is present in the detection region R131 is output.

In the first area A1, a plurality of receivers 20 that receive radio signals from the mobile communication terminal 30 are arranged. The information generation unit 13 of the information output system 10 obtains the distances from the plurality of receivers 20 to the mobile communication terminals 30 based on the reception intensities at the plurality of receivers 20 received by the communication unit 11. The storage unit 12 of the information output system 10 stores position information of the plurality of receivers 20, and the information generation unit 13 includes the distances from the plurality of receivers 20 to the mobile communication terminals 30, and the plurality of receivers 20. The coordinate position of the mobile communication terminal 30 in the target area R1 is obtained based on the position information. Accordingly, when the mobile communication terminal 30 exists in the target area R1, the information generation unit 13 can obtain the coordinate position of the mobile communication terminal 30 existing in the target area R1. The information generation unit 13 can detect the presence / absence of the mobile communication terminal 30 in the stop areas R121, R122, and R123 corresponding to the detection areas of the

detection units

41, 42, and 43, respectively. The information generation unit 13 outputs information indicating the presence / absence of the mobile communication terminal 30 in the stop areas R121, R122, and R123 to the processing unit 14 as the first information D1.

Then, the processing unit 14 outputs the second information D2 based on the first information D1 input from the information generation unit 13 and the third information D3 acquired by the communication unit 11 from the

detection units

41, 42, and 43. .

For example, the operation when the user 2 carrying the mobile communication terminal 30 moves to the region R123 before the gate G3 will be described. At this time, the first information D1 indicating that the mobile communication terminal 30 exists in the region R123 is input from the information generation unit 13 to the processing unit 14, and the detection unit 43 detects the person from the communication unit 11. Is input. When the first information D1 indicating that the mobile communication terminal 30 is present in the region R123 is input to the processing unit 14 and the detection unit 43 detects a person, the user 2 is in the second region A2. It is determined that the person is moving to. At this time, based on the identification information and receiver information of the mobile communication terminal 30 received by the communication unit 11, the processing unit 14 determines that the user 2 of the mobile communication terminal 30 existing in front of the gate G3 It is determined whether or not entry into the area A2 is permitted.

When the processing unit 14 determines that the user 2 of the mobile communication terminal 30 is permitted to enter the second area A2, the processing unit 14 outputs information for opening the gate G3 as the second information D2 to the entrance / exit management server 100. To do. Thus, since the processing unit 14 specifies the position of the gate where the mobile communication terminal 30 exists based on the position information of the mobile communication terminal 30, it is possible to prevent another gate from being accidentally opened, and security. Performance is improved.

When the information for opening the gate G3 is input as the second information D2 from the processing unit 14 to the entrance / exit management server 100, the entrance / exit management server 100 outputs a control signal for opening the gate G3 to the driving unit 101. Open G3. Thereby, the user 2 carrying the mobile communication terminal 30 can enter the second area A2 through the gate G3.

When the gate G3 is opened and the user 2 who has been in the detection area R133 moves to the second area A2, the detection unit 43 outputs the third information D3 indicating that no person exists.
