Description

Non-face-to-face temperature detection device and non-face-to-face temperature detection method {NON-FACE-TO-FACE BODY TEMPERATURE SENSING DEVICE AND NON-FACE-TO-FACE BODY TEMPERATURE SENSING METHOD}

The present invention is a non-face-to-face temperature sensing device and a non-face-to-face temperature sensing method, and more specifically, a non-face-to-face temperature sensing device and non-face-to-face temperature sensing device capable of preventing cross-infection by allowing self-measurement of one's body temperature at all times in a non-face-to-face and non-contact manner. It relates to a method of sensing temperature.

Since ancient times, various infectious diseases have been steadily spreading regularly or aperiodically locally or worldwide. As a common symptom of these infectious diseases, fever symptoms are typical, and accordingly, body temperature measurement is essential to confirm infection.

Therefore, in addition to thermometers distributed to families raising infants and women who manage pregnancy cycles by measuring basic body temperature, schools, academies, day care centers, kindergartens, military units, government offices, buildings, etc. Offices, gyms, department stores, marts, restaurants, movie theaters, churches, temples, and other public places where there is a risk of disease transmission, as well as places with a lot of people moving, such as bus terminals, subway stations, train stations, airports, and ports (hereinafter, abbreviated as'public places'. The demand for thermometers to be used in the system is exploding.

In general, as a thermometer used in each home, compared to conventional mercury thermometers, it is easy to use and has almost no risk of damage, and it can be used repeatedly at short intervals, and it has many advantages that it does not cause severe rejection even when used for infants and toddlers. For this reason, there are many cases of having an ear thermometer, and it is widely used in hospitals.

Referring to FIG. 1 showing an example of a conventional ear thermometer, a probe portion of the ear thermometer protruding long is inserted into the inside of the ear canal, and the temperature of the tissue around the ear canal and the eardrum is detected with infrared rays. It uses a method of measuring the body temperature of the subject. Here, if contaminated with various foreign substances such as earwax or sebum inside the ear canal, accurate body temperature measurement cannot be guaranteed.Therefore, after measuring body temperature with the probe cover, which is a transparent resin cover, attached to the probe part of the ear thermometer each time. , Replace the probe cover every time another user's body temperature is measured.

Since the ear thermometer, which has been widely used in the past, directly inserts the thermometer into the ear (i.e., the ear canal) of the object to be measured, when measuring the body temperature for an unspecified number of people in a public place, rather than an individual, it causes the spread of disease. Because there is a concern that the probe cover needs to be replaced every time, it incurs the cost of small items and the speed of body temperature measurement is also slow, making it unsuitable for use in public places.

Therefore, development of a so-called non-face-to-face fever meter or a non-face-to-face thermometer has been steadily made, and as such an example, Unexamined Patent Publication No. 2003-0074885 (published date: 200309) cited as a prior document in the present application. The forehead type infrared thermometer including'forehead type infrared thermometer and its control method' disclosed in (May 22) is in a trend of being widely used.

That is, as shown in Fig. 2, by using a thermometer equipped with an infrared sensor on the front side, the intensity of infrared rays radiated from the forehead is detected, and the body temperature of the subject is measured therefrom. Done.

Determines the distance between the IR sensor and the target by emitting radiation reflected from the target, receiving the reflected radiation, and determining whether the distance between the IR sensor and the target is within a preset distance based on the characteristics of the reflected radiation. do. If the determined distance is within a predetermined distance, that is, if the thermometer is within the preset distance range, the infrared sensor in the thermometer detects the intensity of infrared radiation emitted from the subject (also referred to as the subject or target), and then the detected infrared ray. The intensity is converted into an electrical signal to measure the temperature of the subject's skin, that is, the body temperature. At this time, it is possible to measure the highest temperature or average temperature by repeating a predetermined number of times, and correct the measurement temperature based on the ambient temperature measured by the temperature sensor and the above-described measurement distance. The measured (or corrected) body temperature is then displayed on the display.

Since the above-described forehead type infrared thermometer avoids direct contact, time and cost for replacing the probe cover are reduced, and it has the effect of reducing the risk of transmission due to contact, but the actual measurement range is very close to a range of several centimeters. , In the case of an infectious disease transmitted in the form of droplets or aerosols, the distance between the tester and the testee is inevitably close, and as a result, there is a high risk of cross-infection from the tester to the tester.

On the other hand, in parallel with the forehead type infrared thermometer described above, infrared thermal imaging cameras are also widely used for fast access processing and securing a distance between a measurer and a subject.

In other words, after placing a thermal imaging camera in an entrance door or a specific passage in a public place, the thermal imaging camera uses a different wavelength of infrared rays emitted from a hot object and a cold object to be measured compared to the surrounding environment. By detecting the infrared radiation emitted from the infrared ray and displaying an image imaged of the difference in wavelength or speed of the infrared ray due to the difference in thermal energy between the surrounding environment and the measurement object, a method of finding a measurement object that generates heat is used.

However, although these thermal imaging cameras have high temperature resolution, they are very expensive and are difficult to install in various places, and since they are greatly affected by the surrounding environment such as ambient temperature, air flow, and humidity, there is a problem of inferior accuracy. .

Hereinafter, a non-face-to-face temperature sensing device according to an embodiment of the present invention will be described in more detail with reference to FIGS. 3 to 5.

3 is a block diagram of a non-face-to-face temperature sensing device according to a preferred embodiment of the present invention, and FIG. 4 is an exemplary view of manufacturing a non-face-to-face temperature sensing device according to a preferred embodiment of the present invention as a product. 5 is an exemplary view of a configuration in which a non-face-to-face temperature sensing device according to a preferred embodiment of the present invention is installed in conjunction with access disinfection equipment.

As shown in FIG. 3, the non-face-to-face temperature sensing device according to an exemplary embodiment of the present invention includes a key input unit 110, a power supply unit 120, a system control unit 130, a distance sensor 140, and a temperature. It includes a detection sensor 150, a speaker 160, a display lamp unit 170, a display unit 180, and a control signal output unit 190.

First, the key input unit 110 includes a confirmation key 112, a control key 114, a selection key 116, and a power key 118, and corresponds to the manipulated key when each key is manipulated by the user. And the electrical input signal is applied to the system controller 130.

Pressing the confirmation key 112 enters the setting mode, for example, as shown in FIG. 7, when the power is applied for the first time, pressing the confirmation key 112 enters the setting mode and inputs a password. The screen is displayed on the display unit 180. Thereafter, the unit position may be moved by the operation of the selection key 116 to be described later, and the password may be input by the control key 114 at each moved position.

Meanwhile, the control key 114 is a key for changing a number at a specific digit of each number displayed on the display unit 180. For example, when the control key 114 is pressed once at the position where 2 is displayed in the middle screen shown in FIG. 7, the number changes to 3. In another example, in order to input 8 at the place where 4 is displayed in the middle screen shown in FIG. 7, it is changed to 8 by pressing the control key 114 4 times.

The selection key 116 is a key for moving between modes in the setting mode or for moving each digit in which a number is displayed. For example, if the confirmation key 112 is pressed in a state in which each digit corresponding to the password is required for each digit in FIG. 7, the confirmation of the password is finished. At this time, when it is determined that the correct password is input, the setting mode is switched.

At this time, for example, the first screen of the setting mode is to change to the ambient temperature coefficient setting mode when the selection key 116 is pressed once on the screen for setting the warning sound (hereinafter, also referred to as an alarm or alarm sound), and the selection key 116 Press) to change to the low limit alarm setting mode. In this way, the selection key 116 is changed smoothly from each setting mode to the next setting mode, and is used to select a mode to be set.

In addition, the selection key 116 is used to move each digit of a number displayed as, for example, four in a specific setting mode. For example, on the basis of the first screen of FIG. 8, when the selection key 116 is pressed, the movement is performed in a circulating manner such as 3→7→0→0→3. Each moved digit may indicate the moved position by blinking a corresponding number or displaying a cursor on it.

The power key 118 can turn on the device by pressing the power key 118 for a preset time (eg, 1 second) while power is applied to the power supply unit 120. When pressed for a set time (eg, 1 second), it can be turned off again. That is, each time the power key 118 is operated, it is alternately switched from turn-on to turn-off and from turn-off to turn-on.

In a preferred embodiment of the present invention, the above-described key input unit 110 is configured as a separate physical key for each of the confirmation key 112, the control key 114, the selection key 116, and the power key 118. desirable. In the case of this configuration, since an expensive display device and a complex system control unit required for software implementation are not required, manufacturing costs can be reduced, and by intuitively manipulating the necessary keys, it is possible to use a separate device. There is an effect that even first-time users can intuitively set up or operate without needing to learn about it.

The power supply unit 120 may be configured with an adapter or 12V battery that converts 220v AC power to an operating voltage (eg, 12V), or a plurality of series-connected low-voltage (eg, 1.5V) batteries or rechargeable batteries.

According to the present invention, since a battery or a rechargeable battery can be used in this way, there is an advantage in that the device can be installed regardless of electric wiring. That is, regardless of the location of the electrical outlet, it can be easily installed in a required place such as a frame, a pillar, a desk, a wall, etc. of an entrance door by a hanging type, an attachment type, an adhesive type, or a magnetic type.

In addition, in another preferred embodiment of the present invention, when attached to an external device used in conjunction with the present non-face-to-face temperature sensing device, for example, a disinfectant gas injection type door, an automatic opening/closing door, etc., it is configured to use the power of the corresponding external device. It could be.

On the other hand, when an adapter is used, for example, an adapter having an input voltage of 100 to 240 V AC, 50/60 Hz and an output voltage of 12 V, which is generally used for small home appliances, can be used.

The system controller 130 includes a signal processing circuit and/or a signal conditioning circuit, and may receive one or more signals from one or more components and perform signal conditioning or processing thereon. Signal conditioning, as used herein, refers to manipulating a signal in such a way that it meets the requirements of the next step for further processing. Signal conditioning includes conversion, amplification, filtering, conversion, biasing, range matching, isolation, and other processes necessary to make a signal suitable for post conditioning processing, from analog to digital (e.g. via an analog-to-digital converter). can do.

Accordingly, the signal processing circuit may include an analog-to-digital converter (ADC) for converting an analog signal from one or more sensor elements into a digital signal. The signal processing circuit may also include a digital signal processor (DSP) that performs some processing on the digital signal.

The system control unit 130 is configured as described above, based on an input signal according to the operation of each key 112 to 118 in the key input unit 110 and a detection signal from the sensors 140, 150, and preset therein. According to the program, the overall system such as the speaker 160, the display lamp unit 170, the display unit 180, and the control signal output unit 190 is controlled.

For example, the system control unit 130 performs a function of setting a normal temperature range such as 35 to 37°C according to the operation of each key 112 to 118 in the key input unit 110. It also performs the function of setting the temperature unit by selecting from Celsius or Fahrenheit. In addition, based on a detection signal that detects the approaching of the object to be measured from the distance detection sensor 140, the temperature detection sensor 150 controls the temperature to sense the temperature, and measured from the temperature detection sensor 150 Body temperature is controlled to be displayed on the display unit 180, the measured body temperature is compared with a preset normal temperature range, and either of the normal display lamp 172 or the abnormal display lamp 174 is controlled to light up. In the case of body temperature, the speaker 160 controls to output a warning sound or an alarm sound.

In addition, based on the temperature detection result of the temperature detection sensor 150 and the operation signals of each of the keys 112 to 118 in the key input unit 110, the ambient temperature compensation according to the use environment of the non-face-to-face temperature detection device can be performed. I can.

In addition, the body temperature measured from the temperature sensor 150 is compared with a preset normal temperature range, and if the body temperature is normal, external devices, such as a security door and a disinfectant gas injection device, are driven to interwork with the non-face-to-face temperature sensing device. Alternatively, the control signal output unit 190 may be driven and controlled to transmit information on the measurement result to external information processing.

The distance detection sensor 140 is a non-contact sensor that detects that a measurement object of a subject, for example, a hand or forehead, is close to a non-face-to-face temperature sensing device, and a Hall element and a permanent magnet whose internal current changes under the influence of magnetism. Proximity sensor or proximity switch, or any type of sensor, also referred to as a human body detection sensor, such as a configuration combining a light sensor, a configuration combining a lamp or light emitting diode and a light sensor, a configuration that detects changes in electrostatic capacity, etc. can be used. When the object to be measured reaches a predetermined distance, an arrival signal may be applied to the system controller 130 to operate as a switch allowing the temperature sensor 150 to measure body temperature.

The temperature detection sensor 150 is composed of a non-contact infrared sensor, detects the intensity of infrared rays radiated from the surface of the object to be measured, such as the forehead or hand, converts it into an electrical signal, and converts the converted electrical signal, that is, the measurement temperature. Apply to the system control unit 130. At this time, as the temperature sensor 150, all conventional infrared sensors used in the field of thermometers and non-contact thermometers may be used.

The speaker 160 may be configured to further include an amplifier (not shown) to expand the sound, and provide a guide voice or a warning (also referred to as an alarm) signal according to the control of the system controller 130 at a preset volume. Amplified and output as a human-audible voice. For example, when it is detected that the subject (person) approaches the non-face-to-face temperature sensing device according to the present embodiment by a human body sensor (not shown), "For body temperature (or heat) measurement, a hand ( Or, please bring your forehead) closer." In addition, when the measurement is not accurately performed, for example, when the temperature measured through the temperature sensor 150 is out of the measurement temperature range, that is, when the temperature is out of 33°C to 42°C, which is expected to be a human body temperature, A guide voice can be output that says, "The measurement was not made correctly. Please put your hand closer to the measurement location." In addition, in the case of a preset normal temperature range within the above-described expected measurement range, that is, a temperature range that is expected to be the normal body temperature of a healthy person, for example, a temperature range of 35 to 37℃, such as "36.5℃. It is normal." Measurement body temperature and normal guidance sound can be output. On the other hand, if it is outside the preset normal temperature range within the above-described expected measurement range, that is, if it is outside the temperature range expected as the normal body temperature of a healthy person, for example, a temperature of less than 35° C. set as hypothermia, or a fever target criterion If the temperature is higher than 37℃, for example, "38℃. Abnormal heat has been detected. Follow the guidance", you can output the measurement body temperature and abnormality guidance voice or emergency bell (alarm).

The display lamp unit 170 may include a normal display lamp 172 and an abnormal display lamp 174 made of an LED lamp or the like.

Among them, the normal display lamp 172 may be composed of, for example, a green LED lamp, and in the case of a temperature range expected to be a normal body temperature of a healthy person, for example, a temperature range of 35 to 37°C, according to the control of the system controller 130 Can be lit,

On the other hand, the abnormal display lamp 174 may be composed of a different color compared to the normal display lamp 172, for example, a red LED lamp, outside the temperature range expected to be a normal body temperature of a healthy person, for example, 35 to 37 ℃. In this case, it may be turned on under the control of the system controller 130,

The display unit 180 may use all existing or subsequently developed conventional display devices such as an existing display device such as an LED (Light Emitting Diode) display device, an LCD (Liquid Crystal Display) device, and an OLED (Organic Light Emitting Diode) device. It can be used to display the English alphabet indicating the setting mode, or a number such as the measured temperature or set value.

In a preferred embodiment of the present invention, it is preferable to configure an LED display device with high brightness and good visibility, simple display configuration and control circuit, and low manufacturing cost. In other words, in order to fulfill the purpose of the product, such as measuring body temperature and confirming heat generation, simplifying the design and configuration of the product, reducing manufacturing cost, and simplifying the user's operation, it is desirable to configure it with an LED display device. . However, the present invention is not intended to exclude other display devices, and various other display devices are selectively employed in order to provide specific settings or information according to the target or purpose of the non-face-to-face temperature sensing device. It is possible.

When the sensing temperature is within the normal temperature range, the control signal output unit 190 outputs a control signal of an external device set to operate in conjunction with the non-face-to-face temperature sensing device under the control of the system controller 130.

As described above, the non-face-to-face temperature sensing device according to the present invention is designed to operate normally in a normal use environment, for example, in a use environment of -10°C to 40°C, approaching within a range of about 10 cm. Body temperature can be measured within 0 seconds on the forehead, wrist, and other human body skin, and it is desirable to design and manufacture within a tolerance of ±0.3°C. The use environment of -10℃～40℃ can be adjusted to the environment of 0℃～30℃ by compromise between the environment in which this non-face-to-face temperature sensing device is installed and the manufacturing cost. Manufacturing costs can be adjusted in consideration of various opinions.

The non-face-to-face temperature sensing device according to a preferred embodiment of the present invention as described above may be mounted on a housing made of plastic resin, metal, or other rigid material, and may be configured as a product as shown in FIG. 4. In the case of the example of Figure 4, except for the bracket and power adapter, it was manufactured with a size of 164×110×32 mm and a weight of 0.6 kg based on the main body, and an output of 12V for an input power of AC100~240V, 　50/60㎐ Operates at an operating voltage of 12V by an adapter having a voltage or a power supply provided by a battery or rechargeable battery of DC 12V, under an ambient temperature of -10 to 30°C and relative humidity in the non-condensing state of 0 to 95%, 1 It is designed to be able to measure within 1 second within a tolerance of ±0.3°C at a measurement distance of ∼10 cm. At this time, the power consumption is 8W or less.

In addition, as shown in FIG. 5, it is installed at one side of the entrance to which the disinfectant gas injection device is mounted, and can operate in conjunction with the entrance permit and gas injection of a subject authenticated with a normal body temperature. As shown in FIG. 5, since the non-face-to-face temperature sensing device according to the present embodiment can be manufactured with a small and lightweight single power source (ie, a battery or a rechargeable battery), it can be confirmed that it is easily installed on one side of the entrance. have.

With the above-described configuration, since it is manufactured as a compact and lightweight product with low power consumption, it is easy to move and install the product freely, and there is an effect that it is possible to quickly and accurately measure body temperature in a non-face-to-face manner.

Hereinafter, a method for detecting a non-face-to-face temperature according to an exemplary embodiment of the present invention will be described in more detail with reference to FIGS. 6 to 9.

6 is a detailed flowchart of a method for detecting a non-face-to-face temperature according to a preferred embodiment of the present invention, and FIG. 7 is a flowchart illustrating a password input process for confirming an administrator in a non-face-to-face temperature sensing device according to a preferred embodiment of the present invention. 8 is an exemplary view showing a process of setting a normal temperature range in a non-face-to-face temperature sensing device according to a preferred embodiment of the present invention, and FIG. 9 is a non-face-to-face view according to a preferred embodiment of the present invention. It is an exemplary diagram showing an example of other adjustment processes such as voice volume of the temperature sensing device, temperature unit, hypothermia alarm setting, distance sensor control, and the like.

In the following description, since the detailed configuration and operation description of each functional block and examples of details have already been described above, the description thereof will be omitted in order to avoid redundant description and clarify the configuration of the method. However, it is not intended to exclude the content, and in performing each procedure of the present non-face-to-face temperature sensing method to be described later, it will be appropriately adopted and implemented by those skilled in the art.

First, referring to FIG. 6, when power is applied from the power supply unit 120 by an adapter or a battery (or rechargeable battery), when the power key 118 is pressed for a predetermined time (eg, 1 second) or more, The non-face-to-face temperature sensing device according to the present embodiment is turned on (S10).

In step S10, when the non-face-to-face temperature sensing device is turned on, a measurement condition is set. For example, when the non-face-to-face temperature sensing device is turned on for the first time, a screen as shown in FIG. 7 is displayed on the display unit 180, and in this screen, the user selects the confirmation key 112 in the key input unit 110 and adjusts By operating the key 114 and the selection key 116 to input a password (eg, 1264 in the fourth screen of FIG. 7 ), the current operator is authenticated as an administrator. Since the detailed operation process has been described in the above-described example, a detailed description thereof will be omitted (S20).

Thereafter, when authentication is completed in step S20, a confirmation key 112, an adjustment key 114, and a selection key 116 in the key input unit 110 in each of the ambient temperature and normal temperature range screens as shown in FIG. 8 ) To set the necessary conditions. At this time, in Fig. 8, the normal upper limit temperature (the first screen in Fig. 8) is 37°C as the factory default value, the measurement environment temperature, that is, the ambient temperature (the second screen in Fig. 8) is 25°C, and the normal lower limit temperature (the third screen in Fig. 8) ) Can be set to 35℃. In the third screen of FIG. 8, it is displayed at 36.5°C, but it can be changed by manipulating the confirmation key 112, the control key 114, and the selection key 116 of the key input unit 110.

In addition, the measurement environment temperature, that is, the ambient temperature (the second screen in Fig. 8) is set to 25°C, but various measurement environments in which this non-face-to-face temperature sensing device is installed (for example, a low-temperature environment such as a normal workshop, a frozen warehouse, etc.) The setting value can be changed according to the same high temperature working environment). At this time, for example, if the ambient temperature is decreased 　10℃　, the measurement 　 temperature drops 　1℃, and if the ambient temperature is increased 　10℃　, the measurement 　 temperature will increase 　0.5℃　. That is, since a deviation occurs in the measurement temperature according to the ambient temperature, it is possible to correct (or compensate) this to measure an accurate body temperature. In particular, in a preferred embodiment of the present invention, instead of a complex and expensive program or an automatic compensation system (although, of course, it is possible to employ such a configuration in the present invention), accurate ambient temperature compensation is possible only with the operation of a simple physical key. Therefore, there is an effect of achieving easy and intuitive operation and low manufacturing cost.

In addition, as shown in Fig. 9, while switching the screen displayed on the display unit 180, the voice volume (e.g., 0 is silent, 1 is low volume, 2 is standard volume, 3 is high volume) (Fig. 9), a reserved function that has not yet been set (the second screen in FIG. 9), selects the temperature unit of Celsius (eg, 1) and Fahrenheit (eg, 2) (the third screen in FIG. 9), whether or not a low temperature warning is notified Setting (e.g., 2 is an alarm sound when the lower limit is below the normal temperature, 3 is to turn off the low temperature warning alarm) (4th screen in Fig. 9), measurement distance setting (e.g., 100 is 5cm, 150 is 10cm, 200 mark 15cm, 250 mark 20cm, 300 mark 25cm), etc. can be changed by operating the confirmation key 112, the adjustment key 114, and the selection key 116 of the key input unit 110. I can.

In the above example, for each setting related to non-face-to-face temperature measurement, such as group configuration, arrangement order, setting range, setting type, etc. of each screen, addition or deletion of various setting conditions required according to the use environment, It can be modified and adopted (S30).

As described above, in a state in which the measurement conditions are set, the distance detection sensor 140 detects whether the object to be measured approaches within a preset range (eg, within 10 cm) (S40).

In step S40, when the object to be measured (eg, hand or forehead) reaches within a preset range (eg, within 10 cm), the distance sensor 140 receives a detection signal indicating that the proximity of the target to be measured has been detected. Generated and applied to the system control unit 130.

The system controller 130 controls the temperature sensor 150 to measure the body temperature when a target detection signal is applied from the distance sensor 140. The temperature detection sensor 150 measures the body temperature of the target subject to be measured, which has reached within a preset range, by using infrared rays or the like, and transmits the measured body temperature value to the system controller 130 (S50).

In step S50, the system controller 130 receiving the measured body temperature value from the temperature sensor 150 determines whether it is within the normal temperature range (eg, 35 to 37°C) set in step S30 (S60).

As a result of the determination in step S60, if the measured body temperature value is within the normal temperature range, the system control unit 130 controls the display unit 180 to display the measured temperature, and the measured temperature is displayed as a number on the display unit 180. It becomes (S70).

At this time, in another preferred embodiment of the present invention, since the subject of concern about infection such as an infectious disease has a problem with high temperature heat above normal body temperature, the hypothermia alarm is turned off according to the set value for the hypothermia alarm in step S30, unless there is a special case. In the case where it is set to, it can be determined as normal even below the lower limit normal temperature.

On the other hand, as a result of the determination in step S60, if the measured body temperature value is within the normal temperature range, the system control unit 130 controls the driving so that the normal display lamp 172 is turned on, and the normal display lamp 172 is, for example, according to the system control unit. It may be lit in green (S80).

In addition, when there is an external device configured to operate in conjunction with the non-face-to-face temperature sensing device according to the present embodiment, the system controller 130 controls the control signal output unit 190 to operate the corresponding external device (not shown). Can be controlled. The control signal output unit 190 generates a control signal or transmits data according to the control of the system controller 130, for example, opening and closing a security door, spraying a disinfectant gas, and transmitting information related to body temperature measurement (S90). ).

Although the above-described steps S70 to S90 are listed as being performed sequentially, the order may be changed to each other or may be performed simultaneously.

Meanwhile, as a result of the determination in step S60, even if the measured body temperature value is not within the normal temperature range, the system controller 130 controls the display unit 180 to display the measured temperature, and the measured temperature is displayed on the display unit 180. It is represented by

In another preferred embodiment of the present invention, as described above, in addition to displaying with numbers, the temperature measured through the speaker 160 may be guided by voice, or may be configured to display numbers and voice guide in parallel (S75). ).

On the other hand, unlike step S80, if the determination result of step S60, the measured body temperature value is not within the normal temperature range, the system control unit 130 controls the abnormal display lamp 174 to be turned on, and controls the abnormal display lamp 174 May be lit in red, for example, according to the system control unit (S85).

In addition, as a result of the determination in step S60, if the measured body temperature value is not within the normal temperature range, the system controller 130 controls the speaker 160 to generate a warning sound/guide voice, and through the speaker 160, the body temperature is abnormal. A notification voice message and a warning sound (alarm sound) may be output (S95).

In another preferred embodiment of the present invention, it is possible to inform the abnormal body temperature and guide re-measurement within a preset number range (eg, 3 times).

The above-described steps S70 to S90 are listed as being performed sequentially, but similar to steps S70 to S90, the order may be changed to each other or may be performed simultaneously.
