Description

Non-contact Thermometer and Driving Method Thereof

The present invention relates to a non-contact thermometer and a method for driving a non-contact thermometer, and more particularly, a general portable non-contact thermometer is configured in a stand shape and a distance measurement function is operated to enable non-face-to-face measurement when power is applied at all times. The present invention relates to a non-contact thermometer and a method of driving a non-contact thermometer that automatically measure body temperature when a wrist or forehead is brought close to the thermometer.

In general, thermometers are divided into contact type and non-contact type. In the case of the contact method, the body temperature is measured by contacting the subject's mouth, ear, armpit, forehead, etc., and there is no problem when used for personal use. There is a problem in spreading viruses such as colds. On the other hand, in the case of the conventional non-contact thermometer, the overall body is formed large, so it is inconvenient to carry it in a pocket or the like. Of course, recently, due to the spread of COVID-19, the technology development of non-contact thermometers has been steadily progressing.

A general non-contact thermometer was developed as a non-contact type in consideration of minimizing infection between patients when measuring body temperature. However, in the case of medical personnel who measure body temperature, since they are close to the subject of body temperature measurement, there is a problem that they are exposed to an environment where they can be exposed to infection, so countermeasures are required.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a diagram illustrating a non-contact body temperature measurement system according to an embodiment of the present invention, FIG. 2 is a diagram showing the non-contact thermometer of FIG. 1, and FIGS. 3A and 3B are diagrams showing the body temperature measurement of the non-contact thermometer of FIG. 1 am.

As shown in FIG. 1 , a non-contact body temperature measurement system 90 according to an embodiment of the present invention includes a non-contact thermometer 100 and a user terminal device 110 .

The non-contact thermometer 100 can be conveniently carried or placed on a stable cradle such as a table to perform non-face-to-face automatic measurement of distance from the user or body temperature, battery and constant power operation, and smart update operation by screen communication such as a smartphone. carry out More specifically, the non-contact thermometer 100 configures a distance measuring sensor for detecting an object in addition to an infrared sensor for non-face-to-face body temperature measurement, and is configured to measure body temperature when an object is detected within a predetermined distance. Non-face-to-face measurement operation is possible only when a constant power source (eg, AC power, DC power from an external device, etc.) is connected. , the thermometer is configured to be able to measure body temperature in an upright state. In addition, the non-contact thermometer 100 communicates with the user terminal device 110 located in the vicinity such as a mobile phone to compensate for the difference in body temperature results generated due to different emissivity according to skin color, and updates skin color-related data. Accurate temperature measurement is possible.

As will be described in more detail later, the non-contact thermometer 100 may be stably mounted vertically on the floor surface by the cradle. And, as shown in FIG. 2, on the inside and outside of the main body, a power port (eg, USB C-type) 200, a scan button 210, a body temperature sensor 220, a distance measurement sensor 230, a display ( 240 ), and a power and mode button 250 . Here, the body temperature measuring sensor 220 may include an infrared sensor, and the distance measuring sensor 2300 may include an IR light emitting/receiving sensor.

According to the above configuration, the non-contact thermometer 100 operates the body temperature sensor 220 to measure body temperature when the distance measured by the distance measuring sensor 230 is within 30 mm as shown in FIGS. 3A and 3B . make this happen Of course, such a distance can be set in various ways, which can be changed depending on the distance at which infection is made, the performance of the sensor, and how the body temperature is measured. will not be limited. The body temperature is measured through the user's forehead as shown in FIG. 3A , or the body temperature is measured through the wrist as shown in FIG. 3B . When the distance is measured by the infrared light emitting/receiving unit and within 30 mm, the measurement operation can be performed for 1 second with a buzzer sound.

Above all, the non-contact thermometer 100 may perform different operations depending on the characteristics of the power source, or more precisely, what type of power source is used. In other words, when commercial or regular power is supplied through the power port 200, it is detected (eg, detected by a sensor or an electric signal, etc.) and distance measurement and body temperature measurement are automatically performed. On the other hand, when DC power such as a battery is used, distance measurement is excluded and only body temperature measurement operation is performed. And the measurement result may be displayed on the display 240 . The power and mode button 250 may turn on the power of the non-contact thermometer 100 or may switch a measurement mode through the mode button. A mode is a button or key that is set to continuously perform a series of operations. Therefore, the range of the measured temperature in the body temperature mode and the life mode may be changed. In addition, when the scan button 210 is pressed, temperature, that is, body temperature may be measured immediately.

Furthermore, the non-contact thermometer 100 according to an embodiment of the present invention performs an operation for precise measurement of body temperature by communicating with a user terminal device 110 such as a nearby smart phone. Herein, the precise measurement generally means that a measurement error may occur depending on skin color when body temperature is measured, and an operation for correcting or compensating for the error according to the skin color is performed. To this end, the non-contact thermometer 100 may set body temperature compensation data related to skin color in an internal memory and perform a correction operation based on this, and may perform screen communication as in FIG. 1 to initially set the data. . Here, screen communication means displaying a black-and-white image in the form of an animation on the screen of the user terminal device 100, of course, such a black-and-white image includes information, and the non-contact thermometer 100 transmits the black-and-white image signal to an optical sensor, etc. It senses and generates data. In other words, if black is defined as binary bit signal '1' and white image is defined as '0', body temperature correction data according to skin color is acquired through a series of binary bit information. As a result, it is possible to compensate for differences in body temperature results caused by different emissivity according to skin color using the obtained body temperature correction data. For example, if tanned skin shows a high body temperature, the actual body temperature may be lower than that, so it can be displayed on the screen by correcting the measured value.

The user terminal device 110 such as a smart phone may be provided around the non-contact thermometer 100 used by the user to perform an operation to assist the operation of the non-contact thermometer 100 . For example, the user terminal device 110 may provide related data to the non-contact thermometer 100 so that the body temperature according to the skin color is precisely measured. Of course, such data storage or update operation may be performed by connecting a tablet PC or a laptop computer to the non-contact thermometer 100 and writing data in the form of an EEPROM. Alternatively, it may be possible through Bluetooth communication between devices, and furthermore, it may be possible to download and update related data by accessing a specific online site through the communication module of the non-contact thermometer 100 without intervention of the user terminal device 110 . . However, in this case, since the manufacturing cost of the non-contact thermometer 100 may increase, in consideration of this point, it is linked with the user terminal device 110 such as a smart phone. will not be limited.

For example, the user terminal device 110 may transmit up to 20 pieces of content to the non-contact thermometer 100 through a mobile app or a web page. Data for about 20 code combinations may be provided to the non-contact thermometer 100 through a black-and-white image in the form of a GIF animation. Of course, the user terminal device 110 can connect to a specific server of an online site when running the app, receive the data, and then provide it to the non-contact thermometer 100. It will not be particularly limited. In addition, the animation-type black and white image can indicate the start by continuously implementing a black image on the screen or continuously implementing a white image on the screen to inform the start position of data, and repeating the black and white images forming one data bundle or group and may be implemented on the screen.

As a result of the above configuration, the embodiment of the present invention improves reproducibility and accuracy through distance sensing and the like, and can operate as an intelligent thermometer. In addition, by configuring accessories such as a cradle, it can be stably mounted on the floor to prevent infection of medical staff. Furthermore, it may not be necessary to install an app for screen communication, and by implementing it as a web page, a low cost and high effect can be obtained by utilizing a TR or IR sensor.

4 is a block diagram illustrating a detailed structure of the non-contact thermometer of FIG. 1 .

As shown in FIG. 4 , the non-contact thermometer 100 of FIG. 1 according to an embodiment of the present invention includes a button unit 400 , a display unit 410 , a backlight 420 , a measurement unit 430 , and a control unit 440 . ), a communication unit 450 , a sound output unit 460 , a status output unit 470 , a battery unit 480 , a power control unit 490 , and some or all of the cradle 495 .

Here, "including some or all" means that some components such as the cradle 495 are omitted to configure the non-contact thermometer 100, or some components such as the measurement unit 430 are configured such as the control unit 440. It means that it can be configured by being integrated with other components, and it will be described as including all in order to help a sufficient understanding of the invention.

The button unit 400 is composed of a power button, a mode button, and a scan button, and can be changed in Celsius and Fahrenheit, and the measurement mode can be changed to a body temperature mode and a life mode to change the range of the measured temperature. Press the scan button to measure the temperature immediately.

The display unit 410 displays the body temperature or the temperature measured in the living mode.

The backlight 420 notifies the user by displaying green (GREEN) when the normal body temperature is displayed and red (RED) when the temperature is high.

The measurement unit 430 measures the temperature by pressing the scan button when operating with a battery, and automatically measures body temperature through an infrared sensor when detecting a distance between the wrist and forehead within 30 mm when the power is always connected. The measuring unit 430 may include a body temperature measuring sensor 431 for measuring body temperature and a distance measuring sensor 432 for measuring a distance, respectively. These heterogeneous sensors may be integrated into one component to constitute the non-contact thermometer 100 .

The control unit 440, for example, a microcomputer (MICOM), when a constant power detection signal is transmitted, the distance measurement function is operated, and when an object is detected within a predetermined distance, the temperature is measured. In addition, the control unit 440 controls buttons, body temperature and distance measurement, power management and battery voltage monitoring, optical sensor signal measurement, LED, and the like. For example, when the sensing signal of the optical sensor is measured through the communication unit 450 , the controller 440 may convert it into data and store it. Of course, the stored data can be regarded as data used to correct body temperature measurement errors according to about 20 skin colors in relation to skin color.

The communication unit 450 is a decoder device for sensing and amplifying a black-and-white on/off signal transmitted from a GIF animation of a smartphone screen. It interprets the sensing signal and generates the desired data. The communication unit 450 may include an optical sensor for sensing or recognizing a black-and-white signal, and an amplifier for amplifying the signal of the optical sensor. As the amplifier, a TR or the like can be used, and of course, an op-amp can also be used. However, manufacturing cost can be reduced by using TR.

The sound output unit 460 emits a buzzer sound when the measurement starts or high temperature is measured. The sound output unit 460 may include a speaker.

The status output unit 470 may include an LED light emitting device, and may inform the outside of the current operating state.

The power control unit 490 operates the non-contact thermometer 100 with two AAA batteries of the battery unit 480 as the main power source, and when the constant power is supplied through the USB-C, the control unit 440 is always provided to the control unit 440 to perform non-face-to-face measurement. Transmits the power detection signal. Through this, a selective control operation of the measurement unit 430 according to the type of power may be performed.

The cradle 495 as a cradle, although not specifically shown in the present invention, may be formed in various shapes, and allows the non-contact thermometer 100 to stand up with respect to the floor surface. Since the cradle 495 may be formed integrally with the non-contact thermometer 10 or may be formed separately, the embodiment of the present invention will not be particularly limited to any one shape. However, it may be desirable to have a structure in which the optical sensor is exposed to the outside in order to recognize an image implemented on a screen of a smart phone or the like.

In addition to the above, the button unit 400, the display unit 410, the backlight 420, the measurement unit 430, the control unit 440, the communication unit 450, the sound output unit 460, the status output unit of FIG. 470 , the battery unit 480 , the power control unit 490 , and the cradle 495 may perform various operations or have a structure, and other detailed information has been sufficiently described above, and thus, the contents thereof will be replaced.

5 is a diagram illustrating a non-contact body temperature measurement process according to an embodiment of the present invention.

For convenience of explanation, referring to FIG. 5 together with FIG. 1 , when the power switch of the non-contact thermometer 100 is turned on, the system is initialized ( S500 ).

Then, when the power button of the non-contact thermometer 100 is briefly pressed, Celsius and Fahrenheit are selected (S501).

When the mode button is pressed, body temperature mode or life mode is selected (S502, S503).

When only the battery is connected, pressing the scan button measures body temperature and displays the result (S505 ~ S507).

When the power is always connected, the thermometer 100 prepares for temperature measurement through the distance measuring sensor.

The non-contact thermometer 100 measures the temperature while a beep sounds when an object is detected within, for example, 30 mm (S508, S509).

The measurement result is displayed on the display (S510). At this time, if the body temperature is out of the normal range, the temperature is displayed in red. This is well shown in Fig. 2(b).

On the other hand, if you press the mode button for 2 seconds, it connects to the mobile (S511, S512).

When the skin color update preparation is completed on the web page, the screen flickers and transmits the data to be set to the thermometer 100 (S520 to S525).

Accurate body temperature measurement is possible when skin color-related data is updated.

Put the thermometer 100 on the smart phone. The update is completed within 10 seconds (S511, S512).

Press and hold the power button to turn off the power.

In addition to the above, the non-contact thermometer 100 of FIG. 1 and the user terminal device 110 such as a smart phone can perform various operations, and since other details have been sufficiently described above, they will be replaced with the contents.

6 is a block diagram illustrating another detailed structure of the non-contact thermometer of FIG. 1 .

As shown in FIG. 6 , the non-contact thermometer 100 ′ according to another embodiment of the present invention includes a communication interface unit 600 , a control unit 610 , a non-contact body temperature management unit 620 , and a part of the sensor unit 630 , or It includes all, and may further include a storage unit, a user interface unit (eg, a voice recognition module, a touch panel, etc.) or a display.

Here, “including some or all” means that some components such as the communication interface unit 600 are omitted to configure the non-contact thermometer 100 ′, or some components such as the non-contact body temperature management unit 620 include the control unit ( 610) or the sensor unit 630, which means that it can be configured by being integrated with other components, and it will be described as including all in order to help a sufficient understanding of the present invention.

The communication interface unit 600 may perform an operation such as setting and updating body temperature correction data related to skin color by performing communication with the user terminal device 110 such as a neighboring smart phone. For this purpose, an optical sensor or an amplifier may be included. Of course, in the embodiment of the present invention, the non-contact thermometer 100' can connect to an external server through a communication network in order to set and update skin color body temperature correction data, and also connect to a nearby laptop computer through USB, etc. in the form of an EEPROM. Since it is possible to write data into the data, it will not be particularly limited to screen communication as shown in FIG. 1 . However, the communication interface unit 600 according to an embodiment of the present invention may be involved in an operation such as setting and updating related data in order to compensate for a difference in body temperature measurement results generated due to different emissivity according to skin color. will be.

The control unit 610 is in charge of overall control operations of the communication interface unit 600, the non-contact body temperature management unit 620, and the sensor unit 630 constituting the non-contact thermometer 100 ′ of FIG. 6 . Typically, the operation of the sensor unit 630 is differently controlled according to the type of voltage currently used. For example, when it is determined that commercial power is supplied, both distance measurement and body temperature measurement are performed. On the other hand, when DC power from the internal battery is used, distance measurement is omitted and only body temperature measurement can be performed. As such, it can be seen that the control unit 610 selectively controls the operation of the sensor unit 630 according to the characteristics or type of the voltage used.

Also, as mentioned above, the controller 610 performs an operation for compensating for a body temperature measurement error caused by a difference in skin color. To this end, an operation for setting data and updating the set data may be performed. The controller 610 may store and update the data in a separate memory, but when configured in the form of a chip, the controller 610 may store and update its data in a memory packaged together with a CPU or the like in the chip. For example, when there is a data storage or update request from the user, the control unit 610 may control the communication interface unit 600 to recognize a black-and-white image in the form of an animation implemented on a screen such as a nearby smart phone. will be.

The non-contact body temperature management unit 620 performs various operations according to an embodiment of the present invention in connection with the control unit 610 . For example, the sensor unit 630 may receive sensing data measured by the sensor and perform a calculation operation. In addition, when the distance measurement data is provided, the non-contact body temperature management unit 620 may calculate the distance and determine whether it is within 30 mm. Of course, it can be seen that the distance measuring sensor emits infrared light, receives the light reflected by the user's forehead or wrist, and calculates the distance based on this. Since the time when light is irradiated is known, and the speed of the infrared light is already known, the distance can be known by integrating the speed with respect to the unit time.

In addition, the non-contact body temperature management unit 620 may request the control unit 610 to selectively control the operation of the sensor unit 630 according to voltage characteristics in connection with the control unit 610 . The non-contact body temperature management unit 620 may load a program related thereto and execute the program by the control unit 610 . Accordingly, the execution result of the program is provided to the control unit 610 so that the control unit 610 controls the sensor unit 630 according to a request for the execution result. In other words, when the non-contact body temperature management unit 620 requests to operate only the body temperature measuring sensor of the sensor unit, the control operation may be performed accordingly. On the other hand, if the distance measurement is performed first, and when the distance measurement is completed, the non-contact body temperature management unit 620 commands the controller 610 to perform the body temperature measurement in a preset manner, the corresponding operation may be performed.

The sensor unit 630 includes a distance measuring sensor and a body temperature measuring sensor. A light-emitting and light-receiving IR diode (or optical device) may be used as the distance measuring sensor, and an infrared sensor or the like may be used as the body temperature measuring sensor. For example, the principle of non-contact temperature measurement by an infrared sensor is composed of a lens, an aperture, a filter, an infrared sensor, and a signal processing unit. It serves to remove unnecessary edge signals. The infrared filter passes only the desired infrared wavelength band to enter the infrared sensor. In the infrared sensor, the optical signal may be converted into an electrical signal, and the signal processing circuit may serve to convert the electrical signal into a temperature. Of course, since the temperature measurement can be made in various forms, the embodiment of the present invention will not be limited to any one form. For example, the infrared sensor may be replaced by using a thermal imaging camera (eg, a CCD camera module, etc.).

In addition to the above, the communication interface unit 600, the control unit 610, the non-contact body temperature management unit 620, and the sensor unit 630 of FIG. 6 may perform various operations, and other details have been sufficiently described above, so the contents I want to replace them with

Meanwhile, as another embodiment of the present invention, the control unit 610 may include a CPU and a memory, and may be formed as a single chip. The CPU includes a control circuit, an arithmetic unit (ALU), an instruction interpreter and a registry, and the memory may include a RAM. The control circuit performs a control operation, the operation unit performs an operation operation of binary bit information, and the instruction interpretation unit converts a high-level language into a machine language and a machine language into a high-level language, including an interpreter or compiler. , the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the non-contact thermometer 100', a program stored in the non-contact body temperature management unit 620 is copied, loaded into a memory, that is, a RAM, and then executed to speed up the data calculation processing speed. can increase

Also, the non-contact thermometer 100 may control the sensor units of the distance measuring sensor and the body temperature measuring sensor so that the distance and body temperature are automatically measured when an external commercial power source is used ( S710 ). For example, when battery power is used, the non-contact thermometer 100 may omit distance measurement and perform only body temperature measurement.

In addition, the non-contact thermometer 100 of FIG. 1 can perform various operations, and since other details have been sufficiently described above, those contents will be replaced.

In addition, although all of the components may be implemented as one independent hardware, some or all of the components are selectively combined to perform some or all functions of the combined components in one or a plurality of hardware program modules It may be implemented as a computer program having Codes and code segments constituting the computer program can be easily deduced by those skilled in the art of the present invention. Such a computer program is stored in a computer-readable non-transitory computer readable media, read and executed by the computer, thereby implementing an embodiment of the present invention.

Here, the non-transitory readable recording medium refers to a medium that stores data semi-permanently and can be read by a device, not a medium that stores data for a short moment, such as a register, cache, memory, etc. . Specifically, the above-described programs may be provided by being stored in a non-transitory readable recording medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.
