Proximity automatic detection type apparatus for recognizing fever and control method thereof

The present invention relates to a device for screening fever by detecting body temperature, and in particular, a proximity automatic body temperature sensing fever screening device and control thereof that can accurately and quickly measure body temperature for a plurality of subjects and automatically determine whether or not a fever is present it's about how

Body temperature refers to the core temperature inside the body. Although body temperature differs depending on the body part, the standard body temperature is the rectal temperature measured at a place more than 6cm from the anus. The normal body temperature of humans is said to be 36.9°C as the axillary temperature, and children tend to be slightly higher than adults and lower for the elderly. In the case of an adult, about 37°C is the normal body temperature, convulsions and pain are induced at about 41°C, and 43.3°C is the maximum temperature limit for maintaining life.

In order to first determine whether a person or livestock is infected with an epidemic, and to track the hospital, the body temperature is measured with a thermal imaging camera or a thermometer to determine whether the person or livestock is infected with an infectious disease.

In particular, Severe Acute Respiratory Syndrom (SARS), H1N1, Ebola virus, Middle East Respiratory Syndrome coronavirus (MERSC; MERS), the recent epidemic Respiratory infectious diseases such as 19 (COVID-19) often pose a risk of widespread transmission, and these infectious diseases are similar to normal diseases, so it is difficult for the infected person to know the infection itself until it is confirmed whether it is a contagious disease. .

However, since these contagious diseases are accompanied by fever, those who have a severe fever by measuring their body temperature are first judged as suspected of being infected, and after quarantine measures, they can determine whether they are infected or not through a close examination.

Therefore, in the prior art, a method has been taken to isolate a person with high fever by individually measuring body temperature with a contact or non-contact thermometer for the subject to be measured. Not only does it cause discomfort and discomfort in measurement and inconvenience of passage even for non-targeted subjects, but it also has the disadvantage of creating an environment in which non-infected persons can become infected through this process.

On the other hand, even in the case of a method of measuring body temperature in a non-contact manner using a thermal imaging camera, there is a limitation in identifying a heat generator because there are problems such as a limited measuring distance, low accuracy for temperature, and vulnerability to external environmental changes.

First, FIG. 1 is a schematic block diagram of a proximity automatic body temperature sensing fever screening device according to an embodiment of the present invention. As shown in FIG. 1, a proximity automatic body temperature sensing fever screening device 100 according to an embodiment of the present invention ) is a device that automatically measures the body temperature of the human body, compares it with the reference body temperature, performs a fever examination, and displays the examination result, and includes a body temperature sensing input unit 110, a control unit 120 and a display unit 130. do.

The body temperature sensing input unit 110 is a component that automatically measures the body temperature of a subject to be measured, and a temperature sensor using a material whose output value changes due to heat emitted from the subject may be used. Body temperature can also be measured by measuring the heat released and measuring the temperature.

In particular, the body temperature sensing unit 111 constituting the body temperature sensing input unit 110 may be a temperature sensor that senses a temperature, and the ambient temperature at a time point at which the body temperature of the subject to be measured is sensed may be simultaneously input. On the other hand, the present invention is not limited thereto, and it may be a contact-type temperature sensor that measures the temperature by directly contacting the human body of the measurement target or a non-contact temperature sensor that measures the temperature without contact, and can measure the body temperature of the measurement target. Anything is possible if there is.

In addition, the body temperature sensing input unit 110 further includes a distance measuring unit 113 including a distance measuring sensor in order to accurately measure the temperature of the subject to be measured. can be configured to start. The distance measuring unit 113 may be a proximity sensor. On the other hand, the present invention is not limited thereto, and does not include a sensor that directly measures the distance between the body part for measuring the body temperature of the subject to be measured and the body temperature sensing input unit 110, and calculates the distance through an image or detects the distance. It may be a device, and anything that can measure a body part and distance for measuring the body temperature of a subject is possible.

Accordingly, the body temperature sensing input unit 110 includes a non-contact medical thermometer and a proximity sensor, so that the forehead, the tail of the eyebrow, the back of the hand, the inside of the wrist, and the inside of the elbow are detected from the effective measurement distance of the thermometer. Automatically measure body temperature. In this case, the non-contact medical thermometer may include a precision non-contact temperature sensor, a sensor optical system, and an electronic control unit, a means for digitally outputting a body temperature value through a body temperature compensation table or a formula according to the measured temperature, and a sensor for sensing the ambient temperature It may further include a unit, and may further include a camera, an image processing unit, and a determination unit for determining the position and exposure for determining the measurement position and identifying the skin exposure state to the surrounding environment, so that at the time when the body temperature of the subject to be measured is measured It allows for more precise measurement and then correction.

The control unit 120 may input measurement information of a subject to be measured.

In this case, the measurement information of the subject to be measured may cause a deviation in body temperature when measuring body temperature, and may include a measurement site for measuring the subject's body temperature, a representative temperature of the measurement environment, and the like.

For example, a person usually has a body temperature of 35.5-37.5 ° C. However, there may be a deviation in body temperature depending on a measurement site for measuring body temperature, and a deviation may also occur depending on the temperature of the measurement environment.

On the other hand, as measurement information of the subject to be measured, the measurement time when the subject's body temperature is measured, which may cause a slight difference in body temperature, the ambient temperature at the time the subject's body temperature is measured, the physical condition of the subject, etc. Although it may be further considered, it is not the object of the present invention to accurately measure the temperature of the body temperature measurement environment, and thus it is not discussed in the present invention.

The control unit 120 includes a calculation unit 121 that converts the body temperature measured by the body temperature sensing input unit 110 into an actual body temperature in consideration of the body temperature according to a preset body temperature measurement position and an ambient temperature range, and the calculation unit 121 ) and an extraction unit 123 for extracting one of the preset result values (normal, mild fever, and fever) corresponding to the actual body temperature calculated in .

The calculating unit 121 may correct the body temperature measured by the body temperature sensing input unit 110 according to the ambient temperature at the time of body temperature measurement, and may also correct the body temperature according to the measurement site. This is because the measured body temperature may be affected by the ambient temperature at the time of measurement, and the body temperature measurement result may be affected depending on the location of the body temperature measurement.

3 and 4 , if the measured body temperature input to the control unit 120 is a value obtained by measuring the body temperature of the forehead or wrist of the subject 10 as an embodiment, that is, among the measurement information of the subject 10 . When the measurement part is the forehead or the wrist and is detected through the body temperature sensing input unit 110 and the measurement information is input to the control unit 120 , the calculation unit 121 calculates the measured body temperature and the preset body temperature corresponding to the forehead in Table 1 below. range can be compared. Table 1 shows the statistical body temperature range for each measurement part of the general public.

In addition, if the ambient temperature at the time of body temperature measurement input to the calculation unit 121 is 24° C., the calculation unit 121 sets the measured body temperature to a preset body temperature based on room temperature (20-30° C.) as shown in Table 2 below ( 34.8° C.), and the body temperature can be converted by Table 3. Table 2 shows the statistical skin temperature for each area where the ambient temperature and body temperature are measured, and Table 3 is a table of body temperature conversion according to the skin temperature for each area where the ambient temperature and body temperature are measured.

The calculation unit 121 converts the measured body temperature into an actual body temperature according to the comparison result as described above and applies it to the extraction unit 123 .

The extraction unit 123 is normal when the actual body temperature applied by the operation unit 121 is included within the preset body temperature range (statistical body temperature range for the general public) shown in Table 1, and when it is as high as about 0.1-0.5 ° C. In the case of an abnormally high value, the result value can be extracted by heat generation. In this case, the temperature range of the mild fever and the temperature range of the fever are examples, and may be adjusted or changed by the proximity automatic body temperature detection fever screening device according to the present invention.

The display unit 130 includes a display unit 131 that displays the result value extracted by the extraction unit 123 among “normal”, “slight fever”, and “fever” in at least one of letters, numbers, and graphic figures, and the result. Depending on the conditions of “normal”, “slight fever”, and “fever”, the value is outputted as a visual signal by lighting with lights of different colors, such as green, yellow, and red, or converted into an audio signal to be used as an auditory signal for the subject and medical staff. An alarm unit 133 for outputting is provided so that not only the subject to be measured but also the medical staff can immediately know the body temperature state of the subject.

A body temperature measurement method using the proximity automatic body temperature sensing fever screening apparatus 100 according to an embodiment of the present invention configured as described above will be described in detail below with reference to FIGS. 1 and 2 . 2 is a flowchart illustrating a control method of a proximity automatic body temperature sensing fever screening apparatus according to an embodiment of the present invention for body temperature measurement.

As shown in FIGS. 1 and 2 , in the control method of the proximity automatic body temperature sensing fever screening apparatus according to an embodiment of the present invention, when the control process is started, first, it waits for body temperature measurement ( S201 ). In the body temperature measurement standby step ( S201 ), power is supplied to the body temperature sensing input unit 110 , the control unit 120 , and the display unit 130 , and is activated for input/output of signals. The control process may be driven as a whole by the control unit 120 or a separate control processor (not shown) may be performed by driving a command stored in a storage device (not shown).

According to the subsequent control, the body temperature sensing input unit 110 detects an adjacent subject to be measured, detects a body temperature measurement site of the subject to be measured (S203), and automatically measures the body temperature of the subject to be measured (S205).

Next, the operation unit 121 of the control unit 120 receives the measured body temperature and measurement information (measured portion and ambient temperature) from the body temperature sensing input unit 110, and sets the measured body temperature to a preset temperature in response to the measurement portion and the ambient temperature. Comparing with the range, the actual body temperature is calculated (S207).

The actual body temperature calculated by the calculation unit 121 is applied to the extraction unit 123, and the extraction unit 123 extracts a result value corresponding to the calculated actual body temperature (S209). The result value corresponding to the calculated actual body temperature may be, for example, data corresponding to “normal”, “slight fever”, and “fever”.

The result value (any one of normal, mild fever, and fever) selected in response to the calculated actual body temperature extracted by the extraction unit 123 is applied to the display unit 130 , and the display unit 130 is applied from the extraction unit 123 . After converting the result value into an electric signal, it is displayed as text or light such as green, yellow, or red through the display unit 131, or output as an audible signal such as an alarm sound or voice through the alarm unit 133 ( S211).

As described above, in the proximity automatic body temperature detection fever screening device according to the present invention, after measuring body temperature using a precise non-contact thermometer, normal body temperature range (35-37° C.), mild fever body temperature range (37.1-37.9° C.), and fever By displaying “normal”, “slight fever” and “fever” as voice signals and/or text signals, or by displaying lamps such as green, yellow, and red, , so that not only the subject to be measured but also the medical staff can immediately know the body temperature status of the subject.

On the other hand, body temperature measurement with a non-contact thermometer has a disadvantage in that it cannot be accurately measured depending on the measurement site, the surrounding temperature, and the degree of exposure to the external environment. It is recommended to take a measurement after resting for at least a minute and allowing the skin to stabilize at the ambient temperature.

Accordingly, in the proximity automatic body temperature detection fever screening device according to the present invention, while keeping in mind that the disadvantage of accurate body temperature measurement with a non-contact thermometer is the ambient temperature and the measurement site, the skin temperature of the person with a fever is higher than that of a normal person, so many normal It can proceed as a clinical means to secure the data of

In addition, the proximity automatic body temperature detection fever screening device according to the present invention uses various temperature measurement equipment and cameras such as a thermal imaging camera and a precision remote measurement non-contact thermometer in addition to the non-contact thermometer to determine whether the measurement site is exposed according to the current state of clothing. It is possible to determine the normal body temperature more precisely and accurately by synthesizing the various measured temperatures.

On the other hand, although the detailed description of the present invention has been described in detail with reference to the preferred embodiments referred to by the accompanying drawings, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by the claims described below as well as the claims and equivalents.
