Description

TECHNICAL FIELD [0001] The present invention relates to a temperature measurement module and a portable temperature measurement device,

The present invention relates to a temperature measurement module and a portable temperature measurement device, and more particularly, to a temperature measurement module and a portable temperature measurement device that use only image sensor integrated thermophiles and a program to detect only a temperature of a predetermined region defined by a focus lens of an infrared lens, To a measuring device.

Generally, an infrared ray refers to a radiation having a wavelength longer than a red light of a visible ray and shorter than a microwave in an electromagnetic wave spectrum. An infrared sensor is a sensor that improves the sensitivity and accuracy by using infrared rays. The infrared sensor senses the infrared ray radiated from the object and measures the temperature of the object. The infrared ray radiated from the infrared ray radiation source is absorbed by the specific gas The concentration of the specific gas is measured, and the physical quantity and the chemical quantity of the target substance are detected, and the detected physical quantity and the stoichiometric quantity are converted into the electricity quantity so as to be signal-processed and outputted. The thermopile infrared sensor is a type of infrared sensor that can measure the radiant energy of infrared rays by connecting n thermocouples in series composed of two kinds of thermoelectric power metals or semiconductors.

A conventional thermopile infrared sensor, which is generally used, is composed of one sensor or a plurality of sensors. Since the receiving angle of the infrared rays received from the outside is relatively wide, about 60 degrees, It is suitable for use in detecting the presence or absence of a large area of heat source but is not suitable for the purpose of tracking the accurate position of the heat source.

According to one aspect of the present invention, a portable temperature measurement device includes at least one thermopile; An infrared lens disposed on the thermopile; And a control arithmetic unit for calculating a temperature value using infrared rays sensed by the thermo file and controlling a program for displaying the temperature value on an image obtained by using the image sensor, The infrared rays emitted from the first region of the object pass through the infrared lens to form a focus on the active region of the thermopile, and a second region of the object from the second region adjacent to the first region The emitted infrared rays pass through the infrared lens to form a focus on the inactive region of the thermopile so that the control operation unit can calculate the temperature of the first region without being affected by the second region.

The program may display at least one temperature measurement point on the image obtained using the image sensor and a temperature value measured at the temperature measurement point.

The entire row of the thermopile may include at least one of bismuth telluride (Bi x Te y ) and antimony telluride (Sb x Te y ).

In addition, the thermopile can be made of a material selected from the group consisting of vanadium oxide (VOx), titanium oxide (Fe 2 O 3 : Ti), lithium-doped nickel oxide (NiO: Li) and barium titanate BaTiO 3 ).

Of course, the scope of the present invention is not limited by these effects.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, Is provided to fully inform the user. Also, for convenience of explanation, the components may be exaggerated or reduced in size.

It is to be understood that throughout the specification, when an element such as a film, region or substrate is referred to as being "on", "connected to", "laminated" or "coupled to" another element, It is to be understood that elements may be directly "on", "connected", "laminated" or "coupled" to another element, or there may be other elements intervening therebetween. On the other hand, when one element is referred to as being "directly on", "directly connected", or "directly coupled" to another element, it is interpreted that there are no other components intervening therebetween do. Like numbers refer to like elements. As used herein, the term "and / or" includes any and all combinations of one or more of the listed items.

In general, the temperature measurement method can be divided into contact type and non-contact type. Non-contact type can be used when contact is impossible, for example, a rotating measuring object, a moving measuring object, The contactless type temperature measuring device is generally used only in the case of a measurement object which can not be contacted subsequently. Since such a noncontact type temperature measuring device is expensive and difficult to handle, a contact type measuring device is widely used.

In recent years, however, there is a growing demand for a simple and inexpensive noncontact type radiation thermometer which can be used for measurement of a relatively low temperature region of about 0 to 300 DEG C including a thermometer of an infant and the like.

Currently, sensors for sensing radiant energy include a photonic type sensor using a photovoltaic effect or a photoconductive effect, a bolometer, a pyroelectric sensor, a thermopile sensor, and a thermal type sensor such as a thermopile sensor.

Among them, a quantum sensor utilizes incident radiation to excite electrons to change the electrical characteristics of the sensor. In general, the detection performance is excellent in a selected wavelength range, and a fast response is obtained. However, this method is disadvantageous in that it is operated at a temperature lower than the liquid nitrogen temperature in order to obtain a predetermined infrared sensitivity.

The thermopile sensor array may refer to a structure in which a plurality of thermopile sensors are arranged in an array. The thermopile sensor is a kind of infrared sensor which can detect the amount of infrared rays emitted from the object statically and dynamically and can be used for finely monitoring the temperature of the object by enabling fine temperature measurement without self heating problem .

These thermopile sensor arrays can be fabricated using existing semiconductor processes and can have higher accuracy and reliability compared to other infrared sensors without cooling and low cost.

Each thermopile sensor in the thermopile sensor array uses a thermocouple as a basic structure, which is formed by forming two materials having different thermoelectrons, one being a junction and the other being open. When a temperature difference occurs between the contact portion and the open portion, the temperature can be sensed by using a Seebeck effect in which a thermoelectric power is generated in proportion to the temperature difference. In the case of such a thermopile sensor array, the electromotive force which appears when the infrared radiation energy is inputted is relatively proportional to the temperature difference between the low temperature part and the high temperature part, and this depends on how much the input energy is efficiently absorbed and used.

Such a thermopile sensor array must absorb as much energy as possible and it is important to design the sensor so that it does not lose the energy once absorbed. It is also important to improve the sensitivity of the sensor, as well as to the field of thermal imaging equipment and night vision In order to apply the thermopile, quick response characteristics other than high output sensitivity may be important.

For this purpose, the role of the black body absorbing infrared rays may be relatively important, and such black bodies should be very blackish and at the same time opaque surface materials (reflectance). It may additionally be possible to control by the addition of a substance capable of controlling the thermal conductivity of the material. Here, the specific structure and technique of the thermopile sensor array are already well known, and a detailed description thereof will be omitted.

1 is a block diagram illustrating a configuration of a portable temperature measuring device according to an embodiment of the present invention.

Referring to FIG. 1, the portable temperature measuring device 1 may include a sensor unit 10, a control operation unit 20, and a screen display unit 30. The sensor unit 10 may include an image sensor 11 and a temperature measurement module 12. The portable temperature measuring device 1 can use, for example, one of a smart phone, a tablet PC and a notebook. For example, if a smart phone is used, the image sensor 11 of the camera capable of photographing can be used as it is. The temperature measurement module 12 may be arranged in a line on the image sensor 11 mounted inside the smart phone.

In addition, the temperature measuring module 12 can measure the temperature of the predetermined region. The control operation unit 20 can calculate a temperature value measured by the temperature measurement module 12 and control a program for displaying the value on an image obtained by using the image sensor 11. [ Also, the program may display at least one temperature measurement point on the image obtained using the image sensor and the temperature value measured at the temperature measurement point through the screen display unit 30.

The temperature measurement module 12 may include an infrared lens 18, a thermopile 13, and the like. The temperature measurement module 12 may further include a board that can be combined with the portable temperature measurement device 1. [ The board can transmit or receive data with the portable temperature measuring device 1 and can be electrically connected.

At least one thermopile (13) can be mounted in the temperature measurement module (12). The thermopile 13 may include one or more selected from the group consisting of vanadium oxide (VOx), titanium-doped iron oxide (Fe 2 O 3 : Ti), lithium-doped nickel oxide (NiO: Li) And barium titanate (BaTiO 3 ).

A thermistor is a resistor whose resistance changes according to the ambient temperature change. The resistance value decreases as the ambient temperature increases. On the contrary, when the ambient temperature increases, the resistance value increases. Thermistor type thermistor having the characteristic of being a secondary thermometer.

The temperature range of the thermistor is in the range of about -50 ° C to 500 ° C, and is applicable to all ranges requiring daily temperature control. Also, since the thermistor can be used in a small size, low cost and high sensitivity, It can be used for temperature sensor and temperature compensation. In the present invention, the thermistor and the thermopile (13) are integrally combined to have a resistance change response characteristic according to the ambient temperature change, which is advantageous in that more accurate temperature measurement can be performed at low cost.

In addition, the entire heat used in the thermopile 13 may include at least one of semiconductor materials such as bismuth telluride (Bi x Te y ) or antimony telluride (Sb x Te y ).

Details of the temperature measurement module will be described later with reference to Figs. 2A to 2B.

FIG. 2A is a schematic view of a temperature measurement module according to a comparative example of the present invention, and FIG. 2B is a sectional view schematically showing a temperature measurement module according to an embodiment of the present invention.

Generally, the active region of a thermopile is an area where infrared rays are absorbed by an infrared ray when the infrared ray is incident, and an inactive region of the thermopile is a region where the infrared ray is reflected, Is a non-light-sensitive area. For example, an infrared sensor using an existing thermopile array is designed to detect infrared rays radiated from an adjacent portion by using a thermopile placed in an out-of-focus region of an infrared lens to offset the effect of an inactive region.

In contrast, the present invention maximizes the effects of the active area and the inactive area, and provides a system that allows a user to precisely measure a temperature at a specific point. More specifically, referring to FIG. 2A, can do. Board 14 may include or be part of any one of, for example, a read integrated circuit (ROIC) chip, a silicon wafer, and a printed circuit board (PCB). The temperature measurement module 12 may be configured using at least one thermopile 13 or a thermopile array using the board 14.

The thermal head 15 can be formed on the prepared board 14. The thermal core 15 may include at least one of bismuth telluride (Bi x Te y ) and antimony telluride (Sn x Te y ), for example. A plurality of heat generators 15 may be used, and they may be connected in series to amplify signals to be used as a high-sensitivity infrared sensor.

The insulating layer 16 can be formed on the entire heat spreading layer 15 formed. Insulating layer 16 is, for example, a silicon nitride (SiN) or silicon oxide (SiO 2) may be used. An infrared absorbing layer 17 may be formed on the insulating layer 16. The infrared absorbing layer 17 may include a material having a high infrared ray absorption rate and may be formed of a material such as a paint, a polymer, a black gold, a black carbon, a carbon nano-tube, An oxide layer, a metal nitride layer, and a black layer formed using nickel chromium (NiCr) or the like.

In addition, the thermoelectric elements 15 may be electrically connected to each other by the conductor portion 15a. For example, a structure may be formed in which the conductor portions are interposed between the n-type thermoelectric element and the p- have.

At this time, the region where the infrared absorbing layer 17 is formed is the active region of the thermopile 13, and the region other than the region where the infrared absorbing layer 17 is formed can be regarded as the inactive region of the thermopile 13. [

The temperature measurement module 12 having two thermopiles 13 side by side as shown in FIG. 2A has a thermopile 15 formed on the board 14, It can be seen that the layer 16 is formed. Finally, the infrared absorbing layer 17 is formed on the insulating layer 16 to form the thermopile 13, and two thermopiles 13 can be arranged side by side.

The infrared lens 18 may be disposed on the thermopile 13 so as to be spaced apart from the thermopile 13. Here, the infrared lens 18 can be fixed to various components such as a separate jig or support, and the specific structure and technique of the jig or support are well known, and a detailed description thereof will be omitted .

The process of measuring the temperature after the temperature measurement module 12 is prepared will be described below.

It is regarded as the first active area A1 of the first thermopile 13 disposed on the left side and the second active area A2 of the second thermopile 13 disposed on the right side. Can be regarded as the inactive region (D) of the thermopile (13). Of course, although not shown here, an area not described on the outer side of each thermopile 13 can also be seen as the inactive area D of the thermopile 13. Fig.

The first infrared ray (R1) emitted from the first region of the object passes through the infrared lens (18) and reaches the thermopile (13). At this time, the focal point of the first infrared ray (R1) may be formed in the inactive region (D) of the thermopile (13).

The second infrared ray (R2) continuously emitted from the second region of the object passes through the infrared lens (18) and reaches the thermopile (13). At this time, the focal point of the second infrared ray (R2) may be formed in the inactive region (D) of the thermopile (13) like the first infrared ray (R1).

Therefore, both the first infrared ray R1 and the second infrared ray R2 are focused on the inactive region D of the thermopile 13, thereby causing interference with each other. Accordingly, it is impossible to precisely distinguish the regions adjacent to each other, and the temperature of the object can not be measured because it is affected by the temperature around the object.

That is, the temperature measurement module, which is inevitably influenced by the ambient temperature, can produce a wide focus to hide the inactive area D of the thermopile 13 and measure the temperature of the wide area of the object. The thermo file 13 is disposed.

However, in order to solve the above problem, the present invention can use a plurality of thermopiles arranged side by side as shown in FIG. 2A, referring to FIG. 2B. Here, specific details of the thermopile 13 are omitted because they are duplicated.

After the thermopile 13 is formed, the infrared lens 18 may be spaced apart from the thermopile 13 by a focal distance. When the infrared lens 18 is arranged in line with the image sensor 11 or is difficult to install due to its complicated structure, the thermopile 13 is mounted on one side surface of the image sensor 11 for easy image capturing and temperature measurement. Or may be arranged in parallel with the image sensor 11 in another place. For example, if they are not arranged in a line, the positions of the image sensor 11 and the infrared lens 18 should be designed to measure the temperature in the same range of regions.

Also, although not shown in the drawing, a temperature measurement module may be designed so that the infrared lens and the thermopile can be 1: 1 compatible. When the thermopiles are configured as one, the active area of the thermopile is one, and the temperature measurement point becomes one, so that the position to measure the temperature can be precisely classified. Since the structure of the temperature measurement module is simple, it is applicable to a portable device having a small volume.

In addition, when the temperature measurement module 12 is configured using the array of thermopiles 13, the temperature of a plurality of regions can be measured by the infrared rays sensed in the active regions of the thermopiles 13. FIG. That is, it is possible to measure the temperature of a plurality of regions corresponding to the focal distance from the infrared lens 18.

2B, the temperature measurement module 12 having two thermopiles 13 side-by-side is shown. The thermopile 15 is formed on the board 14. The thermopile 15 is formed on the thermopile 15, It can be seen that the layer 16 is formed. Finally, the infrared absorbing layer 17 is formed on the insulating layer 16 to form the thermopile 13, and two thermopiles 13 can be arranged side by side.

The temperature measurement module 12 can be formed by disposing the infrared lens 18 on the two thermopiles 13 so as to be spaced apart from each other by the focal distance of the infrared lens 18. Here, the infrared lens 18 can be fixed to various components such as a separate jig or support, and the specific structure and technique of the jig or support are well known, and a detailed description thereof will be omitted .

It is regarded as the first active area A1 of the first thermopile 13 disposed on the left side and the second active area A2 of the second thermopile 13 disposed on the right side. Can be regarded as the inactive region (D) of the thermopile (13). Of course, although not shown here, an area not described on the outer side of each thermopile 13 can also be seen as the inactive area D of the thermopile 13. Fig.

If the first infrared ray (R1) emitted from the first region of the object to be temperature-measured is incident through the infrared lens (18). The incident first infrared ray R1 is refracted by the infrared ray lens 18 to form a focus on the active region A1 of the thermopile 13. [

And a second infrared ray (R2) emitted from a second region adjacent to the first region of the object is continuously incident through the infrared lens (18). The incident second infrared ray (R2) is refracted by the infrared ray lens (18) to focus on the inactive region (D) of the thermopile (13) and be detected.

Finally, a third infrared ray (R3) emitted from a third region adjacent to the second region of the object is incident through the infrared lens (18). The incident third infrared ray (R 3) is refracted by the infrared ray lens so that the second active area (A 2) of the thermopile (13) is focused and detected.

As described above, the active regions A1 and A2 of the thermopile 13 are focused to detect the first infrared ray R1 and the third infrared ray R3, and the inactive region D of the thermopile 13 The second infrared ray R2 is not sensed so that the control calculation unit 20 can calculate only the temperature of the first region without being influenced by the second region.

The temperature value calculated in the control operation unit using the infrared rays sensed by the first infrared ray R1 and the third infrared ray R3 excluding the second infrared ray R2 finally reaches the image sensor 11 through the screen display unit 30. [ Can be displayed on an image obtained by using < RTI ID = 0.0 >

3A to 3B are photographs showing a sample of a portable temperature measuring device according to an embodiment of the present invention.

As shown in Fig. 3A, for example, a smartphone sample is prepared by the portable temperature measurement device 1. Fig. The area displayed by the image sensor 11 of the smartphone can be viewed on the screen display unit 30 of the smartphone. It is also understood that the temperature measurement module 12 is configured to measure the temperature of the same area as at least a part of the area recognized by the image sensor 11 of the smartphone. In this sample, the temperatures of the four regions sensed in the active region of the thermopile array can be measured, and the temperature value and the temperature measurement region of each region are displayed. It is noted that the lower end of the screen display section 30 shows the temperature value of the entire area shown on the screen display section.

FIG. 3B is a photograph showing the result of measuring the temperature of four different regions by a program as shown in FIG. 3A. It can be seen that the temperature corresponding to each temperature measurement area is significantly different. As in FIG. 3A, it can be seen that the temperature value of the entire photographed image area is calculated and displayed at the lower end of the screen display unit 30. FIG.

As described above, according to the present invention, there is provided a thermopile sensor having an infrared lens arranged in line with an image sensor, and a board connectable to a portable temperature measurement device. Each thermopile is provided with an infrared The temperature of a specific area can be detected. This is different from thermal imaging.

Programs used in portable temperature measuring devices can display temperatures measured at a number of temperature measurement points on an image obtained from a visible light camera and also display temperature sensing areas.

The existing thermopile and thermopile arrays are located slightly out of the focal length of the lens to compensate for the accompanying limitation due to the presence of the inactive area, By maximizing the effect of the inactive area of the thermopile, it is possible to detect only the temperature of the focused area of the infrared lens. Also, the temperature measurement position can be recognized by the user through the image sensor.

The portable temperature measuring device thus manufactured uses a thermopile which is inexpensive in cost and thermopiles are spaced apart from the infrared lens by a focal distance so as to narrow the focus so that the temperature of a narrow region of the subject can be sensed. The effect of the thermal image sensor of a high-resolution pixel can be obtained.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
