[5. Outline of temperature measurement of the person to be inspected by the management computer and the temperature measurement terminal]
Hereinafter, the flow of temperature measurement and face recognition of the person to be inspected by the management computer 10 and the temperature measurement terminal 20 of the present embodiment will be described with reference to FIGS. 5, 9 and 10. This process is a process executed by the control unit 13 of the management computer 10 and the control unit 23 of the temperature measurement terminal 20, respectively, but for convenience, the expressions are unified to be performed by the management computer 10 and the temperature measurement terminal 20.

Here, as a precondition, the temperature measuring terminal 20 is in a state where the power is turned on in advance by the administrator 100 at least 10 minutes before the start of temperature measuring at the temperature measuring place 200, which is a place where the person to be inspected always passes when going to and from work. And. Further, the temperature measuring terminal 20 is installed at a suitable height (1.2 m to 1.5 m from the floor surface), and is brought close to a predetermined range (preferably 20 cm to 70 cm) to the faces of the temperature-tested persons having different heights. It is desirable that it is installed so that it can be adjusted upward by a predetermined angle (10 to 20 degrees).

The person to be inspected stands facing the front of the temperature measuring terminal 20 installed in the temperature measuring place 200 at the time of going to work (step S1). The temperature measuring terminal 20 turns off the image display of the liquid crystal display 203 in order to save power when the temperature of the person to be inspected is not measured. That is, as shown in FIG. 9A, the liquid crystal display 203 of the temperature measuring terminal 20 has a frame W indicating a position where the face of the person to be inspected is to be accommodated and a message M1 "Please face the frame and measure the temperature".

In the present embodiment, the temperature measurement and face recognition are performed only when the measurement distance between the face of the person to be inspected and the temperature measurement terminal 20 is within a predetermined distance (for example, 20 cm to 70 cm). That is, even if the measurement distance between the face of the person to be inspected and the temperature measurement terminal 20 is closer or farther than the predetermined range, the temperature of the person to be inspected and the face recognition can be performed, but the measured values vary and the accuracy is not stable. .. This causes anxiety about the accuracy of temperature measurement and face recognition measured by the person to be inspected. In order to solve this problem, by fitting the face F of the person to be warmed imaged by the camera 201 into the frame W displayed on the liquid crystal display 203, the face of the person to be warmed and the temperature measuring terminal 20 are surely kept at a predetermined distance. We ensure that temperature measurement and face recognition can be performed accurately and reliably.

When it is detected for a predetermined time (for example, 0.1 second) that the face of the person to be warmed is within the frame W of the liquid crystal display 203, the temperature measuring terminal 20 automatically performs face recognition and temperature measurement of the person to be warmed. That is, specific information (employee ID, employee ID,) that identifies the person to be warmed by performing face recognition processing as an authentication means by referring to the image of the face of the person to be warmed and the face recognition data stored in advance in the storage unit 21. Generate a name, department, etc. (step S2). The specific information (employee ID, name, department, etc.) of the temperature-tested person specified here is temporarily stored in the storage unit 21.

The temperature measuring terminal 20 authenticates the face of the person to be warmed, and at the same time, measures the body temperature of the surface of the face of the person to be warmed by the infrared heat sensing sensor 202 (step S3). At this time, if the body temperature on the surface of the face of the temperature-testing person is not uniform, the highest body temperature is temporarily stored in the storage unit 21 together with the measurement date and time as the measured value.

While the steps 2 and 3 are being executed, as shown in FIG. 9 (c), the liquid crystal display 203 displays the face F and the frame W of the person to be warmed imaged by the camera 201, and "measurement is in progress." The message M3 of "..." is displayed on the liquid crystal display 203. This is to prevent the possibility that the temperature measurement and face recognition take time due to the movement of the person to be inspected (face movement) and the error of the measured value becomes large when the temperature measurement and face recognition are performed. That is, in the present embodiment, the temperature measuring terminal 20 displays "Measuring ..." on the liquid crystal display 203 when the face of the person to be measured is recognized. This is aimed at the effect of using human psychology and displaying "Measuring ..." to make the subject aware that the temperature is being measured and face recognition is being performed, and to make them think that they cannot move. be. As a result, it is possible to regulate the operation of the person to be inspected in temperature measurement and face recognition, and it is possible to improve the measurement accuracy of temperature measurement and face recognition and shorten the measurement time.

The temperature measuring terminal 20 determines whether or not the measured body temperature on the surface of the face of the subject to be measured is normal (step S4). To determine whether or not this is normal, a predetermined value (for example, 37.1 ° C.) for determining that the body temperature preset as setting information in the storage unit 21 of the temperature measuring terminal 20 is abnormal is compared with the body temperature of the person to be inspected. It is determined by This specified value can be arbitrarily changed by the administrator 100 in units of 0.1 ° C within a predetermined range (35 ° C to 42 ° C).

When the temperature measuring terminal 20 determines that the measured body temperature on the surface of the subject's face is normal (step S4: Yes), the measured body temperature and the measured date and time are displayed on the liquid crystal display 203 of the temperature measuring terminal 20. At the same time, a sound effect indicating normality is emitted from the speaker 208 to notify the person to be warmed (step S5). Specifically, as shown in FIG. 10A, on the liquid crystal display 203, in order from the top, the characters OK, the message M4 "body temperature is normal!", The measured value T (36.3 ° C.), and the measurement date and time K. (2020/07/16 AM7: 50) is displayed. A sound effect (for example, pee) having a pattern for notifying normality is output from the speaker 208.

On the other hand, when the temperature measuring terminal 20 determines that the measured body temperature on the surface of the subject's face is not normal (that is, abnormal) (step S4: No), the temperature is measured on the liquid crystal display 203 of the temperature measuring terminal 20. The body temperature and the measurement date and time are displayed, and a sound effect indicating an abnormality is emitted from the speaker 208 to notify the person to be warmed (step S6). Specifically, as shown in FIG. 10 (b), the liquid crystal display 203 has a sign indicating that entry is prohibited, a message M4 of "body temperature is abnormal!", A measured value T (37.5 ° C.), and a measurement date and time. K (2020/07/16 AM7: 50) is displayed. A pattern sound effect (for example, beep, beep, beep) for notifying an abnormality is output from the speaker 208. After that, a message urging the person to be inspected to return home or go to the hospital is displayed on the liquid crystal display 203 of the temperature measuring terminal 20, and a similar message may be output from the speaker 208.

When the face recognition and temperature measurement of the temperature-tested person are completed, the temperature-measuring terminal 20 manages the specific information (employee ID, name, department, etc.), body temperature, and measurement date and time of the temperature-tested person temporarily stored in the storage unit 21. (Step S7).

The management computer 10 that receives the specific information of the temperature-tested person, the body temperature, and the measurement date and time from the temperature-measuring terminal 20 associates the specific information of the temperature-tested person with the body temperature measured for each subject and the measurement date and time as the attendance / leaving data in the storage unit 11. (Step S8).

The management computer 10 performs an attendance / leaving time management process using the attendance / leaving data for each subject (step S9). In this attendance / leaving time management process, if the measurement date and time of the body temperature of the person to be inspected is before the start time, it is stored as the time to go to work, and if it is after the end time, it is to be the time to leave the office. , Name, department, etc.). Then, at the time of payroll calculation at the end of the month, it will be used to calculate the time to enter and leave the office, and the absenteeism, late arrival, early departure, and overtime hours.

The management computer 10 associates the measured body temperature data of the plurality of temperature-tested persons received from the temperature-measurement terminal 20 with the specific information (employee ID, name, department, etc.) of the plurality of temperature-tested persons, and stores the temperature data in the storage unit 11. I remember. The management computer 10 periodically analyzes and processes the fluctuation of the temperature measurement data for each temperature-tested person stored here (step S10). In this temperature measurement data analysis process, the outbreak of clusters in the population is detected by calculating the infection rate in the population from the incidence of abnormal body temperature in the population. For example, if the infection rate recognized as having an infectious disease such as influenza or a new type of coronavirus exceeds a predetermined rate (for example, 30%), it is judged that a cluster has occurred and it is determined as such. Corresponding measures (closed offices, disinfection, shift to telecommuting) will be taken.

In addition, the management computer 10 analyzes the possibility of having an infectious disease from the change in the temperature measurement data of the population, for example, by collating with the change in the temperature measurement data of a person who has suffered an infectious disease in the past. It is also possible to identify the infectious disease that has occurred. Further, when the measured body temperature of the test subject is abnormal (that is, fever), the administrator 100 listens to the accompanying symptoms (sneezing, coughing, respiratory condition, olfactory abnormality, taste abnormality) from the subject. Then, it is configured so that it can be input by the management computer 10, and the accompanying symptom and the change of the temperature measurement data are combined and analyzed by the temperature measurement data analysis process of the management computer 10 at regular intervals, thereby further infectious disease. It may be possible to identify with high probability whether the disease is influenza or a new type of coronavirus.

Furthermore, when outbreaks such as new coronavirus and influenza are detected, a system that can display a map of outbreaks by region and warn them can be created together with a map application or the like. This also leads to prevention of the spread of outbreaks, and for example, when an outbreak occurs in a nearby area, it is possible to promptly deal with it (change of leave, commuting route, work time, etc.).

In the above-described embodiment, the configuration in which the temperature is measured at the time of attendance and departure of a plurality of temperature-tested persons at a business establishment or the like in which a population is composed of a plurality of temperature-tested persons has been described as an example, but the present invention is not limited to this, and a certain population is not limited to this. The non-contact self-temperature measurement / face recognition system 1 of the present embodiment can be used in various places such as a school, a kindergarten, a nursery school, a factory, and an office.
