Such infrared thermal imaging technology enables non-contact, non-destructive, and real-time measurement of changes in the surface temperature of an object, and is used in various fields such as material thermal property evaluation, deterioration diagnosis, defect inspection, and medical diagnosis through body temperature measurement.

The infrared thermal imaging camera using the thermal imaging technology has the advantage of being able to measure a motor, a large part, an electric panel, etc. at once, and easily detect an overheated part and other dangerous parts no matter how small. In other words, it has the same effect as using thousands of infrared thermometers at the same time. An infrared thermometer can measure the temperature of only one point, whereas a thermal imaging camera can measure the temperature of the entire object (thermal image) at the same time. However, since such a thermal imaging camera is too expensive, it is difficult to spread and expand it.

For example, in the case of a thermal imaging camera, if the image resolution is 80 x 80 pixels, it can have the same effect as using 6,400 infrared thermometers simultaneously. More precisely, in the case of an infrared camera with an image resolution of 640 x 480 pixels, the total number of pixels is 307,200, which is equivalent to using 307,200 infrared thermometers simultaneously. Therefore, thermal imaging cameras are expensive to manufacture.

As a standard, the technology for monitoring the status of the subject to be monitored is presented.

However, since the thermal imaging camera applied to the prior art documents can measure the temperature of a large area or the entire large component, it has the advantage of being able to accurately diagnose the entire problem area, but it is expensive because it is expensive.

1 is a diagram illustrating a mechanical configuration of a panoramic thermal imaging temperature monitoring system 100 using a rotating multi-array thermopoly sensor according to the present invention.

As shown in FIG. 1 , the panoramic thermal image temperature monitoring system 100 according to the present invention may include an electric motor 120 , a rotating shaft 121 , and a thermopoly sensor 130 .

In some examples, the electric motor 120 may include a step motor, a servo motor, or an α-step motor. The step motor is a motor designed to enable positioning operation requiring high precision, and the driver is designed to move simultaneously with the pulse signal output from the control unit 150 (refer to FIG. 3 ) to rotate the motor at a step angle (resolution). Therefore, the open-loop control method is easy to construct and does not require separate tuning unlike the servo motor. Decision driving is possible. In the case of a servo motor, an encoder, which is a rotation detector, is mounted and the rotation position/rotation speed of the motor shaft is fed back to the amplifier. The amplifier calculates the error between the pulse signal (position command/speed command) and the feedback signal (current position/speed) of the controller 150, and controls the rotation of the motor so that this error becomes '0'. Motors, amplifiers, and encoders can perform high-precision positioning operation by establishing a closed loop control method. The α-step motor normally operates under open-loop control according to the command pulse, but switches to closed-loop control during overload to adjust the position. In addition, when overload is continuously applied, an alarm signal is output, and when positioning is completed, an end signal is output to ensure the reliability of the equipment. In other words, it is a motor with fast response due to open loop control, excellent performance due to closed loop control, and high reliability.

In some examples, the electric motor 120 rotates the rotation shaft 121 repeatedly by 180 degrees to 360 degrees at regular time intervals, so that the thermopoly sensor 130 has a thermal image having a plurality of zones at a plurality of angles at regular time intervals. to shoot

In some examples, the thermopoly sensor 130 includes sensors capable of sensing temperature (such as Thermopile, Thermostat, IR) or a plurality of thermopile sensor elements arranged in a horizontal*vertical matrix to form a detection zone as a virtual X-Y-axis coordinate zone. Each detection zone divided by division forms one detection range, and either responds to radiant energy radiated from the object to identify the size by using the large or small number of this detection range, or by recognizing the margin of the detection range. can be identified, and the array is arranged to determine the position and direction of the subject using the X-Y coordinates, i.e., the presence or absence of movement and the direction of movement, and responds to infrared rays emitted from the subject to analog DC voltage can cause

The electromotive force generated by the sensor elements arrayed in the above matrix, that is, the minute analog DC voltage generated in proportion to the current temperature of the sensing object is amplified to a voltage level suitable for signal processing in the amplification unit to output a thermal image having multiple zones. do.

In general, a thermopile sensor is a non-contact temperature measuring device that can detect the temperature of an object's surface without direct contact by detecting infrared rays emitted from the object. can also be used for

Such a thermopile sensor forms a different type of material with a juncture on one side and an open structure on the other side. It refers to a sensor that senses temperature by using the Seebeck effect that thermoelectric power is generated.

This thermopile sensor has a stable response characteristic to direct current radiation, responds to a wide infrared spectrum, and does not require a bias voltage or a bias current.

The operating principle of the thermopile sensor is based on Stefan-Boltzmann's law, which states that "every object radiates energy proportional to the fourth power of absolute temperature from its surface". That is, if the absolute temperature of an object is T, the energy radiated from the object is P, and the emissivity is ε, then P∝εσT ⁴ is obtained.

In this case, σ is the Stefan-Boltzmann constant (5.67×10 ⁻⁸ Wm ⁻² K ⁻⁴ ).

After all, the thermopile sensor measures the temperature by detecting energy proportional to T ⁴ . The energy incident on the sensor element is energy radiated from the subject (A), and energy generated by the temperature around the subject is reflected by the subject. Energy incident on the sensor element (B), energy radiated from the cap of the sensor package by the temperature around the sensor package and incident on the sensor element (C), heat conduction through the sensor package (D), and radiated from the sensor element itself energy (E).

Therefore, when measuring a high-temperature object, the output of the sensor element is proportional to the fourth power of the temperature T of the object according to Equation P∝εσT ⁴ described above.

However, when measuring a low-temperature object, the temperature T value of the object according to Equation P∝εσT ⁴ is not obtained as an output of the sensor element. The reason is that not only the energy (A) incident on the sensor element from the subject according to the Stefan-Boltzmann law but also the sensor element itself radiates energy (E) according to the same law.

Expressing this as a formula, it becomes P∝σ(εT ⁴ + RT _S ⁴ - T ₀ ⁴ ).

In this case, T ₀ is the temperature of the sensor element itself, T _S is the temperature around the subject to be measured, and R is the reflectance. That is, in the high temperature region where the temperature (T) of the subject is much higher than the temperature (T ₀ ) of the sensor element itself (T≫T ₀ ), T ₀ ⁴ in the above formula can be neglected, so the temperature of the subject can be measured, but the temperature of the subject can be measured. Since T ₀ ⁴ cannot be ignored in the low temperature region, the temperature of the subject cannot be accurately measured.

Therefore, it is necessary to compensate for such a component as T ₀ ⁴ . As an example, circuit compensation can be performed. For example, a sensor element for detecting the temperature of a subject, a sensor amplifying unit for amplifying an output signal of the sensor element, a temperature compensation element for detecting the ambient temperature of the subject; A temperature compensator for amplifying the output signal of the temperature compensator, an addition output unit for adding and outputting the output signals of the sensor amplifying unit and the temperature compensating unit, and a constant voltage for applying power to the sensor amplifying unit, the temperature compensating unit, and the summing output unit It may consist of a power supply unit.

Another method is to keep the sensor element at a constant temperature so that the output signal is stabilized so that the sensitivity does not change, and the micro temperature of the sensor element caused by the self-heating of the sensor element and time delay when adjusting the temperature of the sensor element Even the difference can be corrected to improve the sensitivity.

In some examples, the thermopile sensor having a temperature compensation function includes a sensor element in which a surface temperature rises when infrared radiation is detected and a surface charge is generated by a pyroelectric effect, and a first amplifier configured to amplify the surface charge generated in the sensor element And, a substrate made of a thermocouple made of a material with excellent thermal conductivity on which the sensor element is deposited, and either a heat sink or a cooling plate is installed at the bottom of the substrate. A thermo module to control the temperature of the sensor element, a first thermistor deposited on the substrate to detect the temperature of the sensor element and the thermo module, and a signal generated by the first thermistor detecting the temperature is amplified into a signal of a predetermined size Comparison between the voltage amplified by the second amplifier and a preset reference voltage; A temperature control unit that controls the supply direction of the current supplied to the thermo module according to the value to control the cooling plate to operate as either heat absorption or heat generation, and the voltage amplified by the first amplifier by the magnitude of the voltage amplified by the third amplifier It may include a compensator for compensating for a temperature error by adding or subtracting from .

On the other hand, the present invention further includes a control unit 150 (see Fig. 3), which controls the electric motor 120 so that the thermopoly sensor 130 rotates about 180 degrees to about 360 degrees at regular time intervals, By controlling the thermopoly sensor 130 , a thermal image having a plurality of zones at a plurality of angles may be obtained, converted into a panoramic thermal image, and provided. In FIG. 1 , there is one thermopoly sensor 130 , which may take a thermal image for each of a plurality of angles (eg, by five angles).

2 is a schematic diagram illustrating the operation of the panoramic thermal image temperature monitoring system 100 using a rotating multi-array thermopoly sensor according to the present invention.

As shown in FIG. 2 , in the present invention, the controller 150 controls the electric motor 120 to take a thermal image having a plurality of zones for each angle. For example, by rotating the rotation shaft 121 of the electric motor 120 from the left direction to the right direction, the thermopoly sensor 130 provides a thermal image A in the range of 8 degrees, a thermal image B in the range of 14 degrees, and a thermal image in the range of 24 degrees. The thermal image C, the thermal image D in the range of 31 degrees, the thermal image E in the range of 24 degrees, the thermal image F in the range of 14 degrees, and the thermal image G in the range of 8 degrees can be taken, respectively.

3 is a diagram illustrating an electrical configuration of a panoramic thermal imaging temperature monitoring system 100 using a rotating multi-array thermopoly sensor according to the present invention.

As shown in FIG. 3 , the panoramic thermal image temperature monitoring system 100 according to the present invention includes an input/output unit 110 , an electric motor 120 , a thermopoly sensor 130 , an alarm unit 140 , and a control unit 150 . ) may be included.

The input/output unit 110 may input various manipulation signals by a user to the control unit 150 and display various panoramic images output by the control unit 150 . In some examples, the input/output unit 110 may include a touch screen. The electric motor 120 has a rotation shaft 121 , and may rotate the rotation shaft 121 at a predetermined angle according to a control signal from the controller 150 . The thermopoly sensor 130 is coupled to the rotation shaft 121 of the electric motor 120 and rotates 180 degrees to 360 degrees to take a thermal image having a plurality of zones for each angle, and transmit it to the controller 150 . have. The alarm unit 140 may output various alarm signals (such as a fire alarm) as sound or light according to a control signal of the control unit 150 .

The control unit 150 basically controls the electric motor 120 so that the thermopoly sensor 130 rotates 180 degrees to 360 degrees, and also controls the thermopoly sensor 130 to have a plurality of zones by a plurality of angles. A thermal image is acquired and converted into a panoramic thermal image.

In some examples, the controller 150 may include a thermal image storage unit 151 , a panoramic thermal image conversion unit 152 , a temperature change zone determination unit 153 , and/or a subject movement determination unit 154 . These components may be implemented in hardware or may be implemented in software.

The thermal image storage unit 151 may store a thermal image having a plurality of zones for a plurality of angles, and provide the stored thermal image to the panoramic thermal image converter 152 .

The panoramic thermal image converter 152 may receive a plurality of thermal images from the thermal image storage unit 151 and convert them into full panoramic thermal images for 180 degrees to 360 degrees. That is, the panoramic thermal image conversion unit 152 provides a single panoramic thermal image by concatenating a plurality of thermal images for each angle and region.

In some examples, the controller 150 controls the electric motor 120 to repeatedly rotate the thermopoly sensor 130 in a predetermined time unit within a range of 180 degrees to 360 degrees, and at this time, the thermopoly sensor 130 . can be controlled to repeatedly capture thermal images having a plurality of zones for a plurality of angles in a predetermined time unit.

The temperature change zone determination unit 153 may receive the panoramic thermal image over time from the panoramic thermal image converter 152 and determine whether there is a temperature change zone over time. In this case, the temperature change zone determination unit 153 may determine whether there is a temperature change zone over time by comparing the thermal images of the same area at the same angle from a plurality of panoramic thermal images over time.

In some examples, when it is determined by the temperature change zone determination unit 153 that there is a temperature change zone over time, the control unit 150 may output an alarm signal through the alarm unit 140 . Here, the temperature change zone may mean a zone in which the temperature is changed higher or lower than a preset temperature range.

The subject movement determination unit 154 may receive the panoramic thermal image over time from the temperature change zone determination unit 153 and determine whether the temperature change subject moves over time. In this case, the subject movement determining unit 154 may determine whether the subject moves over time by comparing thermal images of the same area at the same angle from a plurality of panoramic thermal images over time.

In some examples, the controller 150 may output an alarm signal through the alarm unit 140 when it is determined by the subject movement determining unit 154 that there is a temperature change subject movement over time. Here, the movement of the temperature change object may mean that the temperature change object moves higher than a preset movement range.

In some examples, the control unit 150 controls the panoramic thermal image received from the panoramic thermal image conversion unit 152 through the input/output unit 110 such as a touch screen, and the time-lapse obtained from the temperature change zone determination unit 153 . The thermal image having the temperature change zone and/or the thermal image including the movement of the temperature change subject over time obtained from the subject movement determining unit 154 may be displayed.

4A to 4K are diagrams illustrating the operation of the panoramic thermal image temperature monitoring system 100 using the rotating multi-array thermopoly sensor according to the present invention.

As shown in FIGS. 4A to 4K , in the present invention, the temperature of each monitoring area can be measured while the monitoring area is divided into several angles and rotated repeatedly at regular time intervals. At this time, an alarm signal can be output when the temperature value measured repeatedly each time is compared and a change of more than the specified value is measured in the specified time unit. In some examples, the sensor detection zone may be divided into sensor detection zone 1 through sensor detection zone 6.

As shown in FIG. 4B , the monitoring system 100 may photograph the sensor detection zone 1 first. In this case, the sensor detection zone may include, for example, a 4*10 zone, and the temperature for each zone may be sensed. In this way, as shown in FIGS. 4B to 4G , a thermal image having a plurality of zones for a plurality of angles can be obtained.

Here, as shown in FIG. 4B , in the sensor sensing zone 2, a temperature (40°C) of a specific zone may be sensed higher than that of other zones (24°C-28°C).

Meanwhile, as shown in FIGS. 4H to 4K , in the sensor detection zone 2, it can be seen that the temperature of the specific zone continues to rise.

In this way, the controller 150 determines that there is a temperature change zone according to time in the sensor detection zone 2, and accordingly, may output an alarm signal through the alarm part 140 . In addition, the controller 150 may determine that there is a movement of the temperature change subject over time, and may output an alarm signal accordingly.
