<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of an infection risk control device according to the first embodiment.
The infection risk control device 200 determines the admission conditions for a person to enter the facility based on the specific unit 241 that identifies the infection level of the person staying in the facility with the infectious substance and the identified infection level. It includes a condition determination unit 242 and an infection risk control unit 243 that controls the infection risk of a person in the facility based on the entrance conditions.

The infection risk control device 200 can be realized by a computer including a processor, a memory, and the like. The higher the infection level, the easier it is for people in the facility to become infected with infectious substances. The specific department 241 can acquire the infection level of the area where the facility is located, which is set by the national government, local governments, etc. in accordance with the guidelines. In addition, the identification unit 241 can also specify the infection level peculiar to the facility in consideration of the health condition, health information or personal information of the visitors. The health status of the visitors can be obtained by having the visitors input the health status of the visitors to the input section provided near the entrance to the facility. Visitor health information can be obtained from the attendee's own device. A visitor's personal information (for example, address, work place, etc.) can be acquired as information associated with the visitor's identification information after identifying the visitor by performing face recognition on the visitor.

The admission condition determination unit 242 can determine different admission conditions over time according to the identified infection level. Admission conditions are conditions that can affect the risk of infection within a facility, such as at least the permissible number of visitors to the facility, the length of time the attendees stay, the permissible social distance of the attendees, and the frequency of disinfection of the attendees. Can include one.

The infection risk control unit 243 notifies the facility guards of the number of visitors to the facility by various notification means (for example, various devices such as computers or smartphones), and the guards restrict the entrance of more than a predetermined number of people. Thereby, the risk of infection in the facility may be controlled. Alternatively, the infection risk control unit 243 may control the infection risk in the facility by limiting the number of visitors through a gate that can be opened and closed, which is provided at the entrance of the facility. Further, the infection risk control unit 243 cooperates with a surveillance camera and a notification device (for example, a digital signage, a speaker, etc.) in the facility, and a device owned by the user (for example, a smartphone or a wearable device), and the infection risk control unit 243 of a person in the facility. It can also be controlled to reduce the risk of infection.

FIG. 2 is a flowchart showing an infection risk control method according to the first embodiment.
The level of infection of the infectious agent of the person staying in the facility is specified (step S11). Based on the identified infection level, the conditions for admission to a person's facility are determined (step S12). The risk of infection of a person in the facility is controlled based on the admission conditions (step S13).

According to the infection risk control device and method according to the first embodiment described above, the infection level in the facility can be specified and the infection risk can be dynamically controlled accordingly.

<Embodiment 2>
FIG. 3 is a schematic view of the infection risk control system according to the second embodiment. Although the facility 1 shows only one floor in FIG. 3, it may have a plurality of floors, and each floor may have a plurality of rooms. Further, the facility 1 may be various buildings such as a restaurant, a sports gym, a stadium, a museum, various stores, a company, and a hospital.

The infection risk control system identifies the level of infection of the infectious agent of the person staying in the facility (user 10 in FIG. 3), determines the admission conditions to the facility based on the identified infection level, and determines the conditions for admission to the facility. Control the risk of infection for one or more people in the facility based on admission requirements.

The infection risk control system can include a gate 250 (for example, a flapper gate) provided at the entrance and exit of the facility 1, a thermo camera 290 provided at the entrance of the facility 1, and an infection risk control device 200. .. The infection risk control device 200 controls each component such as the gate device including the gate 250 and the thermo camera 290. Each component in the infection risk control system is connected via the network N. Networks include wired and wireless networks. The infection risk control device 200 is an information processing device for collecting information from each component and controlling the infection risk in the facility. The gate device including the gate 250 is realized by a computer, and may further include a touch panel 260 (also referred to as an input unit), an entrance detection unit 270 (also referred to as a wireless communication unit), a speaker, and the like. Further, in the infection risk control system, a gate device including a gate 250 (for example, a flapper gate) provided at the exit of the facility 1 may be provided. The gate device provided at this exit may further include an exit detection unit 280 (also referred to as a wireless communication unit). The details will be described later, but the number of visitors in the facility is managed by the entrance detection unit 270 and the exit detection unit 280, and the opening and closing of the gate 250 is controlled according to the number of visitors. Can be restricted. Since the infection risk control system controls the number of visitors or the number of visitors to the facility, it may also be called an entrance control system. A gate device having an entrance detection unit 270 and a gate 250 and an input unit such as a touch panel 260 for allowing visitors to input a health condition or the like may be realized by separate computers. The input unit may have various forms other than the touch panel 260 so that the user can input various information.

In addition, the infection risk control system cooperates with the wearable device 14 and the smartphone 15 possessed by the user 10 via the network N to acquire user information and control the infection risk of a person in the facility. You can also. The infection risk control system also comprises one or more surveillance cameras 490, one or more notification devices 450 such as speakers or digital signage, and one or more disinfection devices 430 connected to each other via a network. You can also. One or more surveillance cameras 490, one or more notification devices 450, and one or more disinfection devices 430 may be dispersedly arranged at various positions, for example, in each room. As will be described in detail later, such a configuration allows the infection risk control system to manage, for example, the distance between each user in the facility, the length of stay of each user, and the frequency of disinfection.

The thermo camera 290 measures the body surface temperature of the user 10 who is a visitor, and transmits the measurement result to the infection risk control device 200. The thermo camera 290 is a device including a predetermined photographing device and a body surface temperature measuring device. The photographing device may be, for example, a stereo camera. The thermo camera 290 photographs the body including the face of the visitor, and transmits the captured image to the infection risk control device 200 via the network N. The thermo camera 290 or the like measures the temperature in the imaging target region, generates a thermography image showing the temperature distribution, and transmits the thermography image to the infection risk control device 200 via the network N. The thermography image may be displayed on the display in real time and presented to the facility manager (for example, a security guard).

On the touch panel 260 of the gate device, the user can self-report his / her health condition (for example, no problem, sickness, tiredness, lack of courage). Past admission history or admission history at multiple locations may be used to determine the authenticity of a self-reported health condition.

Alternatively, the wireless communication function of the admission detector 270 allows the user's health status data (eg, heart rate, blood pressure, or body temperature for the present or past few days) from the user's device (eg, smartphone, wearable device). It can be acquired by the infection risk control device 200.

The infection risk control device 200 can open the gate 250 and allow the user 10 to enter the facility when the temperature measured by the thermo camera 290 for the visitors is below the threshold value (for example, 37 degrees). On the contrary, when the temperature measured by the thermo camera 290 of the visitors exceeds the threshold value (for example, 37 degrees), the gate 250 is kept closed, and an alert is generated via a speaker, a display, or the like. Admission of the user 10 to the facility can be restricted.

The infection risk control device 200 can also determine whether or not a visitor is wearing a mask based on an image taken by the thermo camera 290 or the camera 390. If the visitor is wearing a mask, the gate 250 can be opened to allow the user 10 to enter the facility. On the contrary, if the visitor is not wearing a mask, the gate 250 should be kept closed, and an alert should be generated via a speaker, a display, or the like to restrict the user 10 from entering the facility. Can be done.

Further, the infection risk control device 200 may control the opening and closing of the gate 250 in consideration of the self-reported health condition by the touch panel 260 and the user's health condition data from the device possessed by the user. For example, the infection risk control device 200 opens the gate 250 and facilities the user 10 if the self-reported health condition is not a problem even if the measured temperature of the visitor slightly exceeds the threshold value (for example, several degrees). You can enter inside. This is because even if an alert occurs, the user himself / herself inputs the reason why the body surface temperature is high on the touch panel to cancel the alert. That is, the measured body surface temperature may become high depending on the behavior of the user in front of the gate. For example, the body surface temperature may rise when you are about to be late and run to the facility, or when you eat spicy food during lunch break. Even in such a case, if the self-reported health condition by the touch panel 260 is not a problem, the infection risk control device 200 can open the gate and allow the user to enter the facility. On the contrary, even if the measured temperature of the visitors is slightly below the threshold value (for example, several degrees), if there is a problem (for example, illness) in the self-reported health condition by the touch panel 260, the entrance control device 200 Can keep the gate closed to restrict access to the user's facility.

One or more cameras 390 may be provided in front of the gate 250 in order to acquire the user's behavior in front of the gate. The infection risk control device 200 may control the opening and closing of the gate based on the image taken by such a surveillance camera (for example, camera 390). For example, if multiple images taken (ie, video) show that the user is running, even if the measured temperature of the attendee is slightly above the threshold (eg, a few degrees). The gate can be opened to allow users to enter the facility. Further, the infection risk control device 200 acquires the payment history of the user from, for example, a smartphone, a wearable device, etc., and opens the gate when there is a purchase history of a predetermined food (for example, hot or spicy food), and the user (entrance). Person) can enter the facility.

Also, if the outside temperature is, for example, 35 degrees or higher in the summer, the temperature measured by the visitors with the thermo camera 290 may become high. In this case, the outside air temperature acquisition unit 2413 of the infection risk control device 200 measures the outside air temperature with a temperature sensor, and when the measured outside air temperature exceeds the threshold outside air temperature (for example, 35 degrees), the threshold setting becomes high. (For example, from 37 degrees to 37.5 degrees) may be automatically corrected.

Alternatively, if the outside temperature is 0 degrees or less in winter, the temperature measured by the thermo camera 290 may be low. In this case, the outside air temperature acquisition unit 2413 of the infection risk control device 200 measures the outside air temperature with a temperature sensor, and when the measured outside air temperature is lower than the threshold outside air temperature (for example, 0 degrees), the threshold setting becomes low. (For example, from 37 degrees to 36.8 degrees) may be automatically corrected.

One or more surveillance cameras (for example, camera 490) installed in the facility can capture one or more users in the facility and transmit the captured images to the infection risk control device 200. The infection risk control device 200 can grasp the distance between each user based on the captured image. When the distance between each user is within the threshold value, the infection risk control device 200 uses a notification device (for example, a speaker) or a device (for example, a smartphone, a wearable device) possessed by each user (for example, a smartphone, a wearable device) (for example). Each user can be encouraged to take a social distance (2 meters or more).

Alternatively, a device owned by the user (for example, a smartphone, a wearable device) using an arbitrary positioning system (for example, GPS (Global Positioning System), GNSS (Global Navigation Satellite System), in-facility beacon positioning system, etc.) The infection risk control device 200 may grasp the distance between each user by the position specifying means.

When a device owned by the user (for example, a smartphone or a wearable device, a non-contact IC card, etc.) is held over the device, the entrance detection unit 270 detects the user's entry and identifies the user's identification information (for example, the device). The identification number) is transmitted to the infection risk control device 200. Similarly, the exit detection unit 280 detects the user's exit when a device owned by the user (for example, a smartphone or a wearable device, a non-contact IC card, etc.) is held over the device, and detects the user's exit, and the user's identification information (for example, For example, the device identification number) is transmitted to the infection risk control device 200. In this way, the infection risk control device 200 can manage the number of visitors in the facility. Further, the infection risk control device 200 can also manage the entry time and exit time of each user, that is, the staying time in the facility. When the user's staying time exceeds the threshold staying time determined at the time of admission, the infection risk control device 200 uses the notification device 450 or a device (for example, a smartphone 15 or a wearable device 14) possessed by each user. Therefore, the user can be urged to leave. For example, when an individual is notified of the entrance number at the time of entry and the staying time of the individual exceeds the threshold staying time, the entrance number of the individual is displayed on the digital signage or notified to the user's device to leave. May be urged.

The disinfectant device 430 automatically sprays the disinfectant when the user holds his hand over it. The disinfectant device 430 detects a device (for example, a smartphone 15, a wearable device 14) possessed by each user by short-range wireless communication or the like, and transmits the user's identification number (for example, the device identification number) to the infection risk control device 200. Can be sent. In this way, the infection risk control device 200 can manage the disinfection frequency of each user. When the disinfection frequency of the user is less than or equal to a threshold value (for example, a threshold time or a threshold number of times within a predetermined period), the infection risk control device 200 is a notification device 450 or a device possessed by each user (for example, a smartphone 15, etc.). The user can be urged to disinfect via the wearable device 14). For example, when an individual is notified of the admission number at the time of admission and the staying time of the individual exceeds the threshold staying time, the admission number of the individual is displayed on digital signage or notified to the user's device for disinfection. May be urged.

Next, the configuration of the infection risk control device will be described with reference to FIG.
The infection risk control device 200 is an information processing device (for example, a server) connected to a network (including wired and wireless). The storage unit 210 is a storage device for a hard disk, a flash memory, or the like. The storage unit 210 stores the program 211 and the maximum number of people who can enter the facility 212. Program 211 is a computer program in which the processing of the infection risk control method is implemented.

The memory 220 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information when the control unit 240 operates. The communication unit 230 is a communication interface with the network N. The communication unit 230 may be used for wireless communication. For example, the communication unit 230 may be used to perform wireless LAN communication specified in the IEEE 802.11 series or mobile communication specified in 3GPP (3rd Generation Partnership Project). Alternatively, the communication unit 230 may include, for example, a network interface card (NIC) compliant with the IEEE802.3 series.

The control unit 240 is composed of a processor or the like, and performs various processes of the infection risk control device 200 by reading software (computer program) from the memory and executing the software (computer program). The processor may be, for example, a microprocessor, an MPU (Micro Processing Unit), or a CPU (Central Processing Unit). The processor may include a plurality of processors. The control unit 240 includes a specific unit 241, an admission condition determination unit 242, and an infection risk control unit 243.

The identification unit 241 identifies the level of infection of infectious substances of people staying in the facility. The identification unit 241 can specify the infectious disease level according to the infectious disease response guideline prepared by the national government, local governments, and the like. The identification unit 241 can obtain information on this infectious disease level from a specific website or news site. For example, the infection level according to the infectious disease response guideline may include a normal period (level 1), a caution period (level 2), a vigilance period (level 3), and a dangerous period (level 4). Judgment criteria include (1) the number of new clusters in the city over the past 7 days, (2) the number of serious injuries, and (3) the positive rate over the past 7 days. The normal period (level 1) according to this criterion can be (1) 0 cases, (2) 0 people, and (3) less than 5%. The attention period (level 2) can be (1) 1 to 4, (2) 0 people, and (3) 5%. The alert period (level 3) can be (1) 5 to 15 cases, (2) 0 to 2 people, and (3) 10%. The risk period (level 4) can be (1) 16 or more, (2) 3 or more, and (3) 20% or more. It should be noted that these criteria are merely examples and can be set arbitrarily.

The admission condition determination unit 242 determines the admission conditions for a person's facility based on the identified infection level. As shown in FIG. 4, the admission conditions include, but are not limited to, the allowable number of visitors 2421, the staying time 2422, the allowable social distance 2423, and the disinfection frequency 2424, and reduce the risk of other infections. May include conditions for The permissible number of visitors indicates the percentage of the maximum number of people who can enter the facility. The staying time indicates the time that a visitor can stay from the time of entry, that is, the time of exit. Permissible social distance indicates the permissible distance between users in the facility. The disinfection frequency indicates the time interval (for example, every 30 minutes) or the area interval (for example, every floor, every room, etc.) at which the user should use the disinfection device in the facility.

For example, the admission condition determination unit 242 determines the number of visitors, and for the dangerous period (level 4), the allowable number of visitors (for example, 20 people) is up to 20% of the maximum number of people who can enter the facility (for example, 100 people). ), For the caution period (level 3), the allowable number of visitors (for example, 40 people) up to 40% of the maximum number of people who can enter the facility (for example, 100 people), and for the caution period (level 2) , Up to 70% of the maximum number of people who can enter the facility (for example, 100 people) (for example, 70 people), and during the normal period (level 1), the maximum number of people who can enter the facility (for example, 100 people) The allowable number of visitors (for example, 100 people) can be determined up to 100% of the number of people.

The admission condition determination department 242 sets the staying time to 30 minutes for the dangerous period (level 4), 60 minutes for the alert period (level 3), and 120 minutes for the caution period (level 2). For the normal period (level 1), the length of stay can be determined indefinitely.

The admission condition determination department 242 sets the permissible social distance to 10 meters for the dangerous period (level 4), 5 meters for the alert period (level 3), and 2 meters for the caution period (level 2). In addition, the normal period (level 1) can be determined indefinitely.

The admission condition determination unit 242 disinfects the room for each room during the dangerous period (level 4), for each floor during the alert period (level 3), and for the caution period (level 2). , It can be decided to do it at the time of admission, and the frequency of disinfection can be decided unlimitedly during the normal period (level 1).

In this way, the infectious disease level according to the infectious disease response guidelines prepared by the national and local governments fluctuates over time, so the admission condition determination unit 242 also dynamically determines the admission conditions for the facility. be able to.

Next, another specific example of the infection level will be described with reference to FIGS. 5 and 6.
In this example, the identification unit 241 can identify the infection level specific to the facility. In this case, the body surface temperature of the visitors, the self-reported health condition, or the health condition data acquired from the wearable device or the like can be taken into consideration. Therefore, the specific unit 241 can further include a body surface temperature acquisition unit 2411, a health state acquisition unit 2412, and an outside air temperature acquisition unit 2413. When used in the present specification, the body surface temperature is not the temperature measured by direct contact with the body (for example, underarm) by a thermometer or the like, but the body measured by an image taken by a thermo camera or the like. The temperature of the surface of.

The body surface temperature acquisition unit 2411 acquires a thermography image and a body surface temperature from the above-mentioned thermo camera 290. The health status acquisition unit 2412 provides health status information self-reported to the user's touch panel 260, and user health status data (eg, current or past few days) from a device (eg, smartphone, wearable device) possessed by the user. Get one of heart rate, blood pressure, or body temperature). The outside air temperature acquisition unit 2413 can acquire the outside air temperature from a temperature sensor outside the facility.

FIG. 5 is a table showing input conditions and points for determining the infection level specific to the facility.
The higher the score, the higher the infection level. As for the combination of input conditions and points, "1. An emergency declaration has been issued" is "100 points", and "2. The body surface temperature exceeds the threshold value, but admission was permitted by self-application for physical condition. "Case" is "25 points", "3. Body surface temperature exceeds the threshold value, but it is estimated that there is no problem by the index related to physical condition" is "25 points", "4. Body surface temperature exceeds the threshold value" If it is estimated that there is a problem based on the physical condition index, "25 points", "5. If the number of infected people in the facility area is above the threshold", "25 points", "6. Facility area" When the number of severely ill persons is equal to or higher than the threshold value, "25 points" and the like can be mentioned. The self-application for physical condition is the health condition of the visitor input to the touch panel, and the index related to the physical condition may be the health information acquired from the device possessed by the visitor. It should be noted that the combination of these input conditions and the allocation of points is merely an example, and other input conditions may be included. The input conditions are the above 1.5. And 6, as shown in 6, the condition due to the external environment of the facility may be included, and the above 2.3. And, as shown in 4, the conditions depending on the internal environment of the facility may be included. In addition, in order to determine the infection level specific to the facility, the above 2.3. And only the conditions due to the internal environment of the facility shown in 4 may be used.

FIG. 6 shows the admission conditions determined for the total of each allocation of points.
In this example, the admission condition is the allowable number of visitors. The higher the total score calculated based on FIG. 5, the higher the risk of infection, which can lead to stricter admission conditions. As shown in FIG. 6, if the total score is 100 or more, no one can enter, if it is 75 to 99, up to 25% of the capacity can be entered, and if it is 50 to 74, the capacity can be entered. Up to 50% of the city's attendance can be entered, 25-49 can be entered up to 75% of the capacity, and 25 or less can be admitted without restrictions. For example, "2. If the body surface temperature exceeds the threshold value, but admission is permitted by self-application for physical condition" is "25 points", so if there are 4 or more people who are similarly permitted to enter. Since the total score exceeds 100 points, no one can enter the facility. The admission conditions shown in FIG. 6 are merely examples, and other admission conditions such as the staying time, the allowable social distance, and the disinfection frequency as described above can be used. Admission conditions may be decided according to the infectious disease response guidelines prepared by the national or local governments, or may be decided individually by the facility manager. The categories indicated by the total points (100 or more, 75 to 99, 50 to 74, 25 to 49, 25 or less) correspond to the infection level.

As shown in FIGS. 5 and 6, the identification unit 241 can specify the infection level, and the admission condition determination unit 242 can determine the admission condition according to the infection level. Further, as described above, since the infection level can fluctuate for each visitor, the admission condition determination unit 242 can dynamically determine the admission condition.

Finally, we will explain how to control the risk of infection in the facility based on the determined admission conditions. The infection risk control device 200 controls each component of the infection risk control system to suppress the infection risk in the facility. As shown in FIG. 4, the infection risk control unit 243 of the infection risk control device 200 includes an attendee management unit 2431, a stay time management unit 2432, a distance management unit 2433, and a disinfection frequency management unit 2434.

The entrance management unit 2431 manages the number of visitors or the number of visitors in the facility by the entrance detection unit 270 and the exit detection unit 280, and controls the opening and closing of the gate 250 to limit the number of visitors in the facility. .. As described above, the visitor management unit 2431 can open the gate and allow the visitor to enter when the body surface temperature of the visitor by the thermo camera is equal to or lower than the threshold value. In addition, the visitor management unit 2431 can also determine whether or not the visitor is wearing a mask based on the captured image. The Attendee Management Department 2431 can also consider whether or not a mask is worn, the health condition of the Attendee entered on the touch panel, and the health information acquired from the Attendee's device when deciding whether or not to enter. The attendee management unit 2431 can then count the number of visitors after the admission detection unit 270 confirms that the person has entered. The Attendee Management Department 2431 compares the counted number of visitors with the allowable number of visitors identified by the infection level described above, and if the counted number of visitors reaches the allowable number of visitors, the gate Alerts can be generated via the device's speaker or display and the gate can be left closed to prevent further entry. After that, when it is detected by the exit detection unit 280 that a person in the facility has left, the attendance management unit 2431 reduces the number of visitors to the count so that new visitors can be accepted. Can be done. In this way, the Attendee Management Department 2431 dynamically limits the number of visitors in the facility based on the admission conditions determined for the allowable number of visitors, thereby suppressing the risk of infection and using the facility. Can be continued. In addition, the visitor management unit 2431 can also grasp the infection level of the individual identified by face recognition. Further, in another embodiment, when the number of visitors to the facility is limited, the person who plans to enter the facility (for example, an employee in the case of a building or a ticket purchaser in the case of a stadium) can enter. You may notify by e-mail or the like that the limit on the number of persons has occurred, that the limit has been lifted, and the content of the alert. As a result, it is possible to prevent a person who is planning to enter the facility from being restricted from entering the facility even though he / she has gone to the facility.

The staying time management unit 2432 can acquire the entrance time and the exit time of each user from the entrance detection unit and the exit detection unit, thereby managing the staying time of each user in the facility. At the time of admission, the staying time management unit 2432 issues an admission number to the individual user and notifies the display of the gate device or the user's device. After that, when the user's stay time exceeds the threshold value, the stay time management unit 2432 can prompt the user to leave via the notification device 450 in the facility or the user's device. For example, the notification device 450 may announce a predetermined entrance number to urge the exit of a specific user, or may display a predetermined number on the digital signage to urge the exit of the specific user. Alternatively, the staying time management unit 2432 can notify the device of the user whose staying time exceeds the threshold value to urge the user to leave. In this way, the staying time management unit 2432 dynamically limits the staying time of the visitors in the facility based on the admission conditions determined for the staying time, thereby suppressing the risk of infection and using the facility. Can be continued.

The distance management unit 2433 manages the distance between each user by using the position information of one or more surveillance cameras (for example, camera 490) or the user's device in the facility and the notification device 450. That is, the distance management unit 2433 can grasp the distance between each user based on the image taken by the camera 490 or the position information of each user's device. When the distance between each user is within the threshold value, the distance management unit 2433 can announce to take a social distance by a notification device (for example, a speaker) near the corresponding user. Further, when the distance between the users is within the threshold value, the distance management unit 2433 can directly notify the device of the corresponding user to take the social distance. In this way, the distance management unit 2433 dynamically limits the social distance between the visitors in the facility based on the admission conditions determined for the allowable social distance, thereby suppressing the risk of infection while suppressing the risk of infection. The use of facilities and interaction between users can be continued.

The disinfection frequency management unit 2434 can manage the disinfection frequency of each user by using the disinfection device 430, the user's device and the notification device 450 in the facility. The disinfection frequency management unit 2434 can grasp that the disinfection jet of the disinfection device 430 has been performed and that the disinfection device 430 has detected the user's device. As mentioned above regarding the admission conditions, for example, if the user is determined to disinfect each room, but the user does not disinfect in a certain room, the disinfection frequency management unit 2434 will be asked to disinfect the user's device and the corresponding. Disinfection may be promoted via the notification device 450 in the room. In this way, the disinfection frequency management unit 2434 dynamically limits the disinfection frequency of the visitors in the facility based on the admission conditions determined for the disinfection frequency, thereby suppressing the risk of infection and using the facility. And the interaction between users can be continued.

The infection risk control system according to the present embodiment described above identifies the level of infection of a person staying in the facility with an infectious substance, and based on the specified level of infection, sets the conditions for admission to the facility. It is possible to determine and control the risk of infection of one or more persons in the facility based on admission conditions. In addition, the infection risk control system can identify the infection level specific to the facility, determine the entrance conditions specific to the facility accordingly, and control the infection risk of one or more people in the facility.

<Embodiment 3>
FIG. 7 is a schematic configuration diagram showing an infection risk control system according to the third embodiment.
The components of FIG. 7 are basically the same as the components shown in FIG. 3, and the description thereof will be omitted as appropriate. In FIG. 7, an authentication device 100 connected via a network is added. The authentication device 100 authenticates by registering a face image of a person who should be permitted to enter the facility in advance and collating the registered image with an image taken by a camera 390 or a thermo camera 290. Since the infection risk control device 200 according to the present embodiment controls such authentication by using the authentication device 100, it may also be called an authentication control device. The infection risk control system according to the third embodiment can be used in a more secure building such as a company or a membership store.

FIG. 8 is a block diagram showing the configuration of the authentication device 100 according to the third embodiment. The authentication device 100 includes a face information DB (DataBase) 110, a face detection unit 120, a feature point extraction unit 130, a registration unit 140, and an authentication unit 150. The face information DB 110 stores the user ID 111 and the face feature information 112 of the user ID in association with each other. The face feature information 112 is a set of feature points extracted from the face image. The authentication device 100 may delete the face feature information 112 in the face feature DB 110 in response to a request from the registered user of the face feature information 112. Alternatively, the authentication device 100 may be deleted after a certain period of time has elapsed from the registration of the face feature information 112.

The face detection unit 120 detects a face area included in the registered image for registering face information and outputs it to the feature point extraction unit 130. The feature point extraction unit 130 extracts feature points from the face region detected by the face detection unit 120, and outputs face feature information to the registration unit 140. Further, the feature point extraction unit 130 extracts the feature points included in the face image received from the authentication control device (infection risk control device 200), and outputs the face feature information to the authentication unit 150.

The registration unit 140 newly issues the user ID 111 when registering the facial feature information. The registration unit 140 registers the issued user ID 111 and the face feature information 112 extracted from the registered image in the face information DB 110 in association with each other. The authentication unit 150 performs face authentication using the face feature information 112. Specifically, the authentication unit 150 collates the face feature information extracted from the face image with the face feature information 112 in the face information DB 110. The authentication unit 150 returns to the authentication control device (infection risk control device 200) whether or not the facial feature information matches. The presence or absence of matching of facial feature information corresponds to the success or failure of authentication. The fact that the facial feature information matches (with matching) means that the degree of matching is equal to or higher than a predetermined value.

FIG. 9 is a flowchart showing the face information registration process according to the third embodiment. Here, the information registration terminal (not shown) photographs the body including the face of each user, and transmits a face information registration request including the captured image (registered image) to the authentication device 100 via the network N. The information registration terminal is, for example, an information processing device such as a personal computer, a smartphone, or a tablet terminal.

First, the authentication device 100 acquires the registered image included in the face information registration request (S21). For example, the authentication device 100 receives the face information registration request from the information registration terminal via the network N. Next, the face detection unit 120 detects the face region included in the registered image (S22). Next, the feature point extraction unit 130 extracts the feature points from the face region detected in step S22, and outputs the face feature information to the registration unit 140 (S23). Finally, the registration unit 140 issues the user ID 111, associates the user ID 111 with the face feature information 112, and registers the user ID 111 in the face information DB 110 (S24). The authentication device 100 may receive the face feature information 112 from the information registration terminal and register it in the face information DB 110 in association with the user ID 111.

FIG. 10 is a flowchart showing the face recognition process by the authentication device 100 according to the third embodiment. First, the feature point extraction unit 130 acquires a face image for authentication included in the face recognition request (S31). For example, the authentication device 100 receives a face recognition request from the authentication control device (infection risk control device 200) via the network N, and obtains face feature information from the face image included in the face recognition request as in steps S21 to S23. Extract. Alternatively, the authentication device 100 may receive facial feature information from the authentication control device (infection risk control device 200). Next, the authentication unit 150 collates the acquired face feature information with the face feature information 112 of the face information DB 110 (S32). When the face feature information matches, that is, when the degree of matching of the face feature information is equal to or higher than a predetermined value (Yes in S33), the authentication unit 150 identifies the user ID 111 of the user whose face feature information matches (S34). , The user ID 111 specified that the face authentication was successful is returned to the authentication control device (infection risk control device 200) (S35). When there is no matching face feature information (No in S33), the authentication unit 150 returns to the authentication control device (infection risk control device 200) that the face recognition has failed (S36).

In step S32, the authentication unit 150 does not need to try to collate with all the face feature information 112 in the face information DB 110. For example, the authentication unit 150 may preferentially try to collate with the face feature information registered in the period from the day when the face recognition request is received to several days before. This can improve the collation speed. Further, when the above-mentioned preferential collation fails, it is advisable to collate with all the remaining facial feature information.

Next, the configuration of the infection risk control device according to the third embodiment will be described with reference to FIG.
The infection risk control device 200 is an information processing device (for example, a server) connected to a network (including wired and wireless). The storage unit 210 is a storage device for a hard disk, a flash memory, or the like. The storage unit 210 stores the program 211 and the maximum number of people who can enter the facility 212. Program 211 is a computer program in which the processing of the infection risk control method is implemented.

The identification unit 241 identifies the level of infection of the infectious substance of the person staying in the facility, in particular, in the present embodiment, the level of infection specific to the visitors and the facility. The identification unit 241 may further include an authentication control unit 2414 in place of or in addition to the outside air temperature acquisition unit 2413. In this case, the body surface temperature of the visitor, the health condition by self-report, the health condition data acquired from the wearable device, etc., and the personal information of the visitor specified by the authentication (for example, address, work place, etc.) are taken into consideration. You can also do it.

The body surface temperature acquisition unit 2411 acquires a thermography image and a body surface temperature from the above-mentioned thermo camera 290. The health status acquisition unit 2412 provides health status information by self-report to the user's touch panel 260 and the user's health status data (for example, current or past several days' heartbeat) from a device (for example, a smartphone or a wearable device) possessed by the user. Number, blood pressure, or body temperature). The authentication control unit 2414 controls face authentication for the face area of the user (for example, a person in front of the gate) included in the captured image. The authentication control unit 2414 causes the authentication device 100 to perform face authentication based on the face feature information acquired from the captured image for the visitors, and acquires the face authentication result from the authentication device 100. For example, the authentication control unit 2414 transmits a face authentication request including the acquired face feature information to the authentication device 100 via the network N, and receives the face authentication result of each user from the authentication device 100.

The specific unit 241 according to the present embodiment can identify an individual by face recognition and acquire an external environment (personal information) related to the specified individual. For example, personal information can include the number of infected persons and the number of severely ill persons in the area where the specified individual lives and the company and department to which the specified individual belongs. That is, the specific unit 241 can specify the infection level in consideration of such personal information.

The admission condition determination unit 242 determines the admission conditions for a person's facility based on the identified infection level. Admission conditions include, but are not limited to, permissible number of visitors 2421, staying time 2422, permissible social distance 2423, disinfection frequency 2424, etc., but may include other conditions for reducing the risk of infection. .. The permissible number of visitors indicates the percentage of the maximum number of people who can enter the facility. The staying time indicates the time that a visitor can stay from the time of entry, that is, the time of exit. Permissible social distance indicates the permissible distance between users in the facility. The disinfection frequency indicates the time interval at which the user should use the disinfection device in the facility.

For example, the admission condition determination unit 242 sets the number of visitors to the allowable number of visitors up to 20% of the maximum number of people who can enter the facility during the dangerous period (level 4), and the number of visitors during the alert period (level 3). Allowable number of visitors up to 40% of the maximum number of people who can enter the facility, and during the caution period (level 2), the number of people allowed up to 70% of the maximum number of people who can enter the facility during the normal period (level 1) ) Can be determined as the allowable number of visitors up to 100% of the maximum number of people who can enter the facility.

As described above, since the infectious disease level specified by the specific unit 241 fluctuates with time, the admission condition determination unit 242 can also dynamically determine the admission conditions to the facility.

FIG. 12 is a table showing input conditions and points for determining infection levels specific to an identified individual and institution.
The higher the score, the higher the infection level. As for the combination of input conditions and points, "1. An emergency declaration has been issued" is "100 points", and "2. The body surface temperature exceeds the threshold value, but admission was permitted by self-application for physical condition. "Case" is "25 points", "3. Body surface temperature exceeds the threshold value, but it is estimated that there is no problem by the index related to physical condition" is "25 points", "4. Body surface temperature exceeds the threshold value" If it is estimated that there is a problem based on the physical condition index, "25 points", "5. If the number of infected people in the facility area is above the threshold", "25 points", "6. Facility area""25points" when the number of severely ill persons is above the threshold value, "7. 30 points" when the number of severely ill persons in the area where the specified individual lives is above the threshold value, "8. Area where the specified individual lives" If the number of severely ill persons is above the threshold value, "30 points", "9. If the number of infected persons in the company (department) to which the specified individual belongs is above the threshold value", "35 points", "10. Specified individual "When the number of severely ill persons in the company (department) to which the company belongs is above the threshold value" is "35 points". The self-application for physical condition is the health condition of the visitor input to the touch panel, and the index related to the physical condition may be the health information acquired from the device possessed by the visitor. It should be noted that the combination of these input conditions and the allocation of points is merely an example, and other input conditions may be included. The input conditions are the above 1.5. And 6, as shown in 6, the condition due to the external environment of the facility may be included, and the above 2.3. As shown in 4 and 4, the condition due to the internal environment of the facility may be included, or the condition due to the external environment of the specified individual as shown in 7 to 10 above may be included. In addition, in order to determine the infection level specific to the identified individual and institution, the above 2.3. And only the conditions due to the internal environment of the facility shown in 4 and the conditions due to the external environment of the specified individual as shown in 7 to 10 above may be used.

As described above, the specific unit 241 can specify the infection level, and the admission condition determination unit 242 can determine the admission conditions. Further, as described above, since the infection level can fluctuate for each visitor, the admission condition determination unit 242 can dynamically determine the admission condition.

Finally, we will explain how to control the risk of infection in the facility based on the determined admission conditions. The infection risk control device 200 controls each component of the infection risk control system to suppress the infection risk in the facility. The infection risk control unit 243 of the infection risk control device 200 includes an attendance management unit 2431, a stay time management unit 2432, a distance management unit 2433, and a disinfection frequency management unit 2434.

The entrance management unit 2431 manages the number of visitors or the number of visitors in the facility by the entrance detection unit 270 and the exit detection unit 280, and controls the opening and closing of the gate 250 to limit the number of visitors in the facility. .. Further, as described above, the attendee management unit 2431 can open the gate and allow the visitor to enter when the face recognition is successful and the body surface temperature of the visitor by the thermo camera is below the threshold value. .. The visitor management unit 2431 can also consider the health condition of the visitor input to the touch panel and the health information acquired from the visitor's device when deciding whether or not to enter. The attendee management unit 2431 can then count the number of visitors after the admission detection unit 270 confirms that the person has entered. The Attendee Management Department 2431 compares the counted number of visitors with the allowable number of visitors identified by the infection level described above, and if the counted number of visitors reaches the allowable number of visitors, the gate Alerts can be generated via the device's speaker or display and the gate can be left closed to prevent further entry. After that, when it is detected by the exit detection unit 280 that a person in the facility has left, the visitor management department 2431 reduces the number of visitors and makes it ready to accept new visitors. Can be done. In this way, the Attendee Management Department 2431 dynamically limits the number of visitors in the facility based on the admission conditions determined for the allowable number of visitors, thereby suppressing the risk of infection and using the facility. Can be continued.

The stay time management unit 2432 can acquire the entrance time and the exit time of each user by the entrance detection unit and the exit detection unit, thereby managing the stay time of each user in the facility. At the time of admission, the staying time management unit 2432 issues an admission number to the individual user and notifies the display of the gate device or the user's device. After that, when the user's stay time exceeds the threshold value, the stay time management unit 2432 can prompt the user to leave via the notification device 450 in the facility or the user's device. For example, the notification device 450 may announce a predetermined entrance number to urge the exit of a specific user, or may display a predetermined number on the digital signage to urge the exit of the specific user. Alternatively, the staying time management unit 2432 can notify the device of the user whose staying time exceeds the threshold value to urge the user to leave. In addition, the staying time management unit 2432 may set the staying time shorter for the individual visitors who are determined by the specific unit 241 to have a high infection level, for example, based on the table of FIG. In this way, the staying time management unit 2432 dynamically limits the staying time of the visitors in the facility based on the admission conditions determined for the staying time, thereby suppressing the risk of infection and using the facility. Can be continued.

The distance management unit 2433 manages the distance between each user by using the position information of one or more surveillance cameras (for example, camera 490) or the user's device in the facility and the notification device 490. That is, the distance management unit 2433 can grasp the distance between each user based on the image taken by the camera 490 or the position information of each user's device. When the distance between each user is within the threshold value, the distance management unit 2433 can announce to take a social distance by a notification device (for example, a speaker) near the corresponding user. Further, when the distance between the users is within the threshold value, the distance management unit 2433 can directly notify the device of the corresponding user to take the social distance. At this time, the distance management unit 2433 can also perform matching between the image captured by the camera 490 and the registered image to identify an individual in the captured image. In addition, the distance management unit 2433 may be set to take a larger social distance to the individual visitors who are determined to have a high infection level based on, for example, the table of FIG. 12 by the specific unit 241. .. In this way, the distance management unit 2433 dynamically limits the social distance of the visitors in the facility based on the admission conditions determined for the permissible distance, thereby suppressing the risk of infection and using the facility. And the interaction between users can be continued.

The disinfection frequency management unit 2434 can manage the disinfection frequency of each user by using the disinfection device 430, the user's device and the notification device 450 in the facility. The disinfection frequency management unit 2434 can grasp that the disinfection jet of the disinfection device 430 has been performed and that the disinfection device 430 has detected the user's device. As mentioned above, the admission conditions were decided to be disinfected for each room, but if the user did not disinfect in a room, the disinfection frequency management unit 2434 would send the user's device and the corresponding room. You may be encouraged to disinfect via the notification device 450. In addition, the disinfection frequency management unit 2434 may set the disinfection frequency high for the individual visitors who are determined by the specific unit 241 to have a high infection level, for example, based on the table of FIG. In this way, the disinfection frequency management unit 2434 dynamically limits the disinfection frequency of the visitors in the facility based on the admission conditions determined for the disinfection frequency, thereby suppressing the risk of infection and using the facility. And the interaction between users can be continued.

The infection risk control system according to the present embodiment described above identifies an individual visitor, identifies an infection level specific to the visitor and the facility, and determines admission conditions specific to the visitor and the facility accordingly. , The risk of infection of one or more people in the facility can be controlled. Furthermore, it is possible to set stricter admission conditions for specific visitors with a high infection level and reduce the risk of infection in the facility.
