Description

Black ice removal system using invisible light {BLACK ICE REMOVAL SYSTEM USING INVISIBLE LIGHT}

The present invention relates to an apparatus for removing black ice through radiant heat of invisible rays and a method for controlling the same, and more particularly, to a method for removing black ice on a road surface by controlling the irradiation of radiant heat of invisible rays to remove radiant heat of invisible rays. It relates to a black ice removal device and a control method thereof.

The condition of the road surface and the securing of the driver's view have the most important effects on securing the driving stability of the vehicle. For example, snow or frozen ice accumulated on the road surface due to snowfall significantly reduces the frictional resistance of the road surface, and black ice, which is caused by freezing of the road surface due to dew condensation or temperature drop even after rainfall, is more dangerous because it is not observed by the driver's eyes. .

In addition, when caused by a rapid temperature difference between the air and the ground, even if there is no snowfall, water vapor in the air immediately freezes as it touches the ground, resulting in black ice as described above. At this time, even fog Since black ice cannot be observed even when the driver's vision is blocked, it can lead to a large-scale accident on roads where high-speed driving such as highways occur. However, there is no special alternative other than the driver's attention.

Various technologies have been proposed to provide a safe driving environment despite the rapidly changing road surface conditions due to weather conditions. For example, salt water injection facilities are installed on roads designated as icing risk areas to prevent freezing by lowering a certain point on the road surface by spraying calcium chloride on the road, or by burying a heating wire at the bottom of the road to supply current to the heating wire according to weather conditions. Applied to prevent freezing.

However, these salt water injection facilities can cause salt water containing calcium chloride to flow into adjacent farmland through the road surface, contaminate the soil, or cause corrosion by being deposited on driving vehicles. When the spraying is performed, there is a problem in that the durability of the facility is lowered due to the deterioration of the concrete.

In addition, even in burying the heating wire on the road, a lot of cost is required for installation, and excessive electric energy is consumed for operation, so there is a limit to low economic feasibility.

In order to solve this problem, the applicant applied for "anti-slip device by thin ice on the road" of Korean Patent Registration No. 10-2221831 (registered on February 23, 2021, hereinafter referred to as 'prior art literature') and received the registration there is a bar The prior art document suggested that the hot air be blown to the road by using a pressure spraying nozzle continuously provided in the blower pipe while transferring the hot air to the blower pipe using the hot air generating means and the blower fan.

However, this hot air blowing method has a limitation in that the hot air does not reach the opposite side of the road because the pressure of the hot air discharged from the pressure spray nozzle is significantly lowered.

Accordingly, there is a need for a technology for removing black ice by irradiating radiant heat in addition to methods such as salt water spray, hot air spray, and hot wire burial.

Specifically, the light source unit 110 may include a light source that emits long-wavelength invisible light, for example, a light source that emits infrared rays, and may be configured to enable heat transfer through which it is invisible to the human eye. Such invisible light refers to electromagnetic waves having a longer wavelength than visible light, and has a function of transferring heat through invisible light.

And, the light source emitting invisible light may include a metal resistance wire such as nickel or chromium implemented in the form of a coil or spring, and has a heating range of approximately 500 degrees to 1400 degrees. Except for the resistance loss due to the specific resistance of the metal resistance wire, all remaining power is dissipated as heat, so that it can function as a heating element.

That is, the light source unit 110 emits invisible light, irradiates the emitted invisible light to a certain area through the reflector 120 to be described later, and transfers heat through the irradiated invisible light. And the heat transferred in this way is defined as a kind of radiant heat.

In addition, the irradiation range described in this specification means the irradiation range of invisible light, and the irradiation range of invisible light is the same as the irradiation range of radiant heat transmitted through invisible light. to be defined as

Accordingly, invisible to the human eye, but generated through the light source unit 110 is irradiated to the irradiation range of a certain area of the road surface, so that radiant heat is transmitted to the irradiation range, and through this, to the irradiation range. There is an effect of removing the black ice by increasing the temperature of the ice.

In addition, the light source unit 110 is connected to at least one or more actuators and is movable in all directions. Here, the actuator refers to a mechanical device used to move or control the system, and is a term including, for example, a driving device using electricity, hydraulic pressure, or compressed air.

Accordingly, the light source unit 110 can be moved in any direction up, down, left, or right through the actuator.

In addition, the reflector 120 may be implemented in a form surrounding the light source unit 110 to reflect invisible rays generated from the light source unit 110 so as to be irradiated in a desired direction.

Here, the reflector 120 may be implemented as a parabolic mirror so that the invisible light generated from the light source unit 110 is directed straight forward, and the parabolic mirror may include a concave mirror whose reflecting surface is a rotational paraboloid, , there is no spherical aberration, and light incident parallel to the axis can be converged at the focal point.

In addition, the communication unit 130 may receive temperature information of the inside of the road surface from each of a plurality of temperature sensors embedded in the road surface. Here, the communication unit 130 may perform communication with at least one of a temperature sensor, a server, and an external device, and may perform communication with BT (BlueTooth), IoT (Internet of Things), WI-FI (Wireless Fidelity), Zigbee, IR (Infrared ), serial interface, universal serial bus (USB), long range (LoRa), long term evolution (LTE), etc.

For example, the communication unit 130 can communicate with a cloud server and interwork with all devices connected to the cloud server. Here, the communication unit 130 may transmit humidity information, camera recognition information, status and operation information of the black ice removal device 100, etc. to the server in addition to the road surface temperature information acquired through the temperature sensor.

On the other hand, the processor 140 extracts an area where the temperature sensor is disposed, in which the internal temperature of the road surface is measured to be less than or equal to a predetermined temperature based on the temperature information, and places the irradiation range of the invisible light of the light source unit in the extracted area. The light source unit can be moved.

Specifically, when temperature information is received from each of a plurality of temperature sensors buried inside the road surface, the processor 140 determines whether each of the received temperature information is equal to or less than a predetermined temperature, and determines whether or not each of the received temperature information corresponds to the temperature information that is less than or equal to the predetermined temperature. By detecting the temperature sensor, an area where the detected temperature sensor is disposed may be extracted.

In addition, the processor 140 may control the light source unit 110 to move through an actuator so that the irradiation range of the light source unit 110 is located in an area where the detected temperature sensor is disposed.

Accordingly, the irradiation range of the light source unit 110 is positioned with respect to the area corresponding to each of the plurality of temperature sensors buried in the road surface, so that the invisible light is irradiated to the irradiation range and radiant heat is transmitted, and thus the road surface By allowing the temperature to be maintained above a certain temperature, it is possible to prevent the formation of conditions in which black ice can be generated on the road surface or to melt and remove the generated black ice.

Here, the light source unit 110 is spaced apart from the reflector 120 by a predetermined distance, and the invisible light generated from the light source unit 110 is reflected by the reflector 120 at the predetermined distance and irradiated while maintaining straightness. It is set to be investigated as a range.

2 is a diagram illustrating configurations of a light source unit and a reflector according to an embodiment of the present invention.

Referring to FIG. 2 , a light source unit 110 and a reflector 120 are shown. Specifically, the light source unit 110 may be implemented as a plurality of invisible light sources, that is, heating coils, and the reflector 120 The light source unit 110 is spaced apart from the reflector 120 by a predetermined distance 10 through the support 220 penetrating through it.

In addition, the light source unit 110 may be connected to the actuator 220 through the support 210, and the actuator 220 may adjust a preset distance 10 between the light source unit 110 and the reflector 120.

Here, the actuator 220 controls the reflection angle of the invisible light emitted from the light source unit 110 through the reflector 120 by adjusting the predetermined distance 10 between the light source unit 110 and the reflector 120. It is possible to control the irradiation range or area of the non-directive ray.

On the other hand, the reflector 120 is implemented in a form surrounding the light source unit 110 and has a parabolic mirror shape, and the invisible light generated from the light source unit 110 through the parabolic mirror can be irradiated with a straight line.

Here, the inner surface 121 of the reflector 120 is plated with metal so that the invisible light generated by the light source unit 110 is reflected, and the outer surface 122 of the reflector 120 is covered with a material such as ceramic. A heat dissipation process or a heat preservation process may be performed so that hot heat is not emitted to the outside due to the heat generated from the light source unit 110 .

In addition, while the reflector 120 is implemented in the form of a parabolic mirror, the inner surface of the reflector 120 may be surface-treated to have a constant angle of reflection for each constant inner diameter in order to increase the straightness of the invisible light generated from the light source unit 110. And, there may be several inner circumferences.

For example, the inner surface of the reflector 120 may be intaglio or embossed for each inner diameter so that the invisible light generated from the light source unit 110 is incident on the intaglio or embossed surface and reflected in a straight line. there is.

Meanwhile, each of the temperature sensors embedded in the road surface is spaced apart from each other at predetermined intervals, and a virtual predetermined area is set on the road surface based on the predetermined interval, and the predetermined area may correspond to the irradiation range of the light source unit. .

3 is a diagram for explaining a temperature sensor buried in a road surface, a virtual predetermined area, and an irradiation range according to an embodiment of the present invention.

Referring to FIG. 3 , a part of the road is shown and both the right road and the left road are marked. In addition, temperature sensors are embedded and installed inside each of the right road and the left road, and a preset area is set around each of the installed temperature sensors and is indicated by a dotted line.

Specifically, in some areas of the right road, the temperature sensors 310, 320, and 330 are spaced apart from each other by a predetermined distance and installed in a buried area, and the predetermined area around each of the temperature sensors 310, 320, and 330 ( 311, 321, 331) may be generated respectively.

The preset areas 311, 321, and 331 generated in this way are set to have the same area as each other to divide a partial area of the road, and one area 321 of the preset areas 311, 321, and 331 is the light source unit 110. Each of the predetermined areas may be set to correspond to the irradiation range of the invisible light emitted from the light source unit 110 as corresponding to the irradiation range of the invisible light emitted from the light source unit 110 .

Here, as described above, since the irradiation range of the invisible light is the same as the irradiation range of the radiant heat transmitted through the invisible light, each of the preset areas is the amount of the radiant heat transmitted through the invisible light emitted from the light source unit 110. It is set to correspond to the investigation range.

However, each of the predetermined areas corresponds to the irradiation range of the invisible light emitted from the light source unit 110 and serves as a reference for the irradiation position, and the area of the irradiation range is necessarily the same as the preset area or the shape is the same. does not mean that

That is, the processor 140 may set the location and range of each of the preset regions as a virtual region through each of a plurality of temperature sensors buried in the road surface, and irradiation of the light source unit 110 based on each virtual region as a unit. It can be moved to match the range.

Meanwhile, the temperature sensor buried in the road surface includes a first temperature sensor and a second temperature sensor, and the processor 140 measures the temperature measured through each of the first temperature sensor and the second temperature sensor to be equal to or less than a preset temperature. In this case, the light source unit 110 may be moved so that the irradiation range of the light source unit 110 is sequentially positioned with respect to the first preset area corresponding to the first temperature sensor and the second preset area corresponding to the second temperature sensor. .

4 is a diagram for explaining movement of an irradiation range for a plurality of temperature sensors according to an embodiment of the present invention.

Referring to FIG. 4 , assuming that a first temperature sensor 320, a second temperature sensor 310, and a third temperature sensor 330 among a plurality of temperature sensors installed on a road correspond to the first temperature sensor 320 A first preset area 321 corresponding to the second temperature sensor 310 and a third preset area 331 corresponding to the third temperature sensor 330 are set. .

And, among these temperature sensors, the temperature measured through each of the first temperature sensor 320 and the second temperature sensor 310 is measured below a preset temperature, and the temperature measured through the third temperature sensor 330 is a preset temperature. When it is measured that the set temperature is exceeded, the processor 140 controls the light source unit 110 so that the irradiation range of the light source unit 110 is sequentially located from the first preset area 321 to the second preset area 311. can move

That is, the processor 140 positions the irradiation range 321' with respect to the first preset region 321 to transfer radiant heat to the first temperature sensor 320 buried in the first preset region 321. When the measured temperature exceeds the predetermined temperature, the light source unit 110 may be controlled to move or rotate to the left so as to sequentially position the irradiation range 311' with respect to the second predetermined area 311. there is.

Through this, the processor 140 determines the temperature measured by the first temperature sensor 320 and the second temperature sensor 310 buried in the first preset area 321 and the second preset area 311. Temperatures corresponding to the first preset region 321 and the second preset region 311 may be maintained at constant temperatures by exceeding the set temperature.

For example, the processor 140 continuously moves the light source unit 110 so that the temperature corresponding to the first preset area 321 and the second preset area 311 can be maintained at 2 degrees Celsius. Radiant heat to the first preset area 321 and the second preset area 311 by positioning the irradiation range of the invisible light generated from the first preset area 321 and the second preset area 311 You can control the transmission.

And, while the light source unit 110 is being irradiated, the processor 140 continuously receives temperature information inside the road surface from each of the temperature sensors embedded in the road surface, and when the received temperature information exceeds a predetermined temperature, the light source unit ( Since the transfer of radiant heat through the irradiation of the invisible light generated in 110) is not necessary, the irradiation of the light source unit 110 may be stopped.

For example, the processor 140 may use the first temperature sensor 320 and the second temperature sensor 320 buried in the first preset area 321 and the second preset area 311 while the light source unit 110 is being irradiated. If it is determined that the temperature measured by the sensor 310 exceeds 2 degrees Celsius, the irradiation of the light source unit 110 may be stopped, and through this, the first preset area 321 and the second preset area 311 The temperature corresponding to can be maintained at 2 degrees Celsius.

Meanwhile, the processor 140 calculates the area of the first irradiation range for the first preset area according to the distance from the light source unit 110 to the first preset area and the irradiation angle, and calculates the area of the first irradiation range from the light source unit 110 to the second preset area. An area of the second irradiation range for the second preset area is calculated according to the distance to the set area and the irradiation angle, and the first preset area and the second preset area have the same temperature change in the first irradiation range. The irradiation time of the light source unit 110 may be differently controlled based on the area and the area of the second irradiation range.

5A is a diagram for explaining a process of controlling irradiation time for a plurality of temperature sensors according to an embodiment of the present invention.

Referring to FIG. 5A , in a situation in which the first temperature sensor 510 and the second temperature sensor 520 are buried and installed in a road surface, a first preset area 511 corresponding to the first temperature sensor 510 and a second temperature sensor 510 are provided. A second preset area 521 corresponding to the temperature sensor 520 may be set.

And, when the light source unit 110 irradiates the invisible light to the first preset area 511, the first irradiation range ( 511') is generated, and similarly, when the light source unit 120 irradiates the invisible light to the second preset area 521, the distance from the light source unit 110 to the second preset area 521 and the irradiation angle Accordingly, a second irradiation range 521' may be created.

Here, since the distance and irradiation angle from the light source unit 110 to the first preset area 511 and the distance and irradiation angle from the light source unit 110 to the second preset area 521 are different from each other, the first irradiation range The area of 511' and the area of the second irradiation range 521' are also different from each other, and the processor 140 controls the area of the first irradiation range 511' and the area of the second irradiation range 521', respectively. will yield

And, when the area of the second irradiation range 521' is calculated to be larger than the area of the first irradiation range 511', the amount of heat transfer through the invisible light per unit area of the second irradiation range 521' is the first. Since the heat transfer amount per unit area of the irradiation range 511' is smaller than the heat transfer amount through the invisible light, the processor 140 determines that the temperature change of the second predetermined area 521 corresponding to the second irradiation range 521' is the first The irradiation time for the second irradiation range 521' is shorter than the irradiation time for the first irradiation range 511' so as to be the same as the temperature change of the first preset region 511 corresponding to the irradiation range 511'. The irradiation time may be differently controlled so that the light source unit 110 irradiates longer.

That is, since the heat transfer amount per unit area of the second irradiation range 521' is smaller than the heat transfer amount per unit area of the first irradiation range 511', the irradiation time for the second irradiation range 521' is reduced to that of the first irradiation range 511'. '), so that the temperature change of the second preset region 521 and the temperature change of the first preset region 511 are the same.

As described above, the processor 140 calculates the area of the irradiation range for the preset area based on the distance from the light source unit 110 to the preset area and the irradiation angle, and calculates the area of the irradiation range for each preset area. Based on the difference in area, irradiation time for each irradiation range may be differently set.

Meanwhile, the processor 140 determines the irradiation flow for the first and second irradiation ranges based on the difference between the first temperature sensor and the second temperature sensor and the predetermined temperature and the irradiation time of the light source unit 110. and, when the third investigation range is generated, the investigation movement line may be calculated in consideration of the third investigation range.

Here, the irradiation movement line means a trajectory in which the irradiation range of the light source unit 110 moves as the processor 140 controls the movement of the light source unit 110 .

That is, since the temperature on the road surface is different from each other and the difference value from the preset temperature is also different from each other, the processor 140 calculates the order of which area to irradiate the invisible light generated from the light source unit 110 from, , the investigation movement is calculated according to the calculated order.

The processor 140 may determine the order based on the difference between the temperature sensor and the predetermined temperature and the irradiation time when calculating the order of irradiating the invisible light generated from the light source unit 110 .

5B is a diagram for explaining a process of calculating an irradiation movement line for a plurality of temperature sensors according to an embodiment of the present invention.

Referring to FIG. 5B , it is assumed that the first temperature sensor 530 and the second temperature sensor 540 are embedded in the road surface, and the temperature measured through the first temperature sensor 530 and the second temperature sensor 540 When the temperature measured through is lowered to a predetermined temperature or less, a process for the processor 140 to calculate an irradiation line is as follows.

For example, the difference between the temperature measured through the first temperature sensor 530 and the preset temperature is 4.5 degrees Celsius, and the difference between the temperature measured through the second temperature sensor 540 and the preset temperature. A case where the difference between the temperature measured through the first temperature sensor 530 and the preset temperature at 3 degrees Celsius is greater than the difference between the temperature measured through the second temperature sensor 540 and the preset temperature. to assume

At this time, the first irradiation range 531 ′ located in the first preset area 531 corresponding to the position of the first temperature sensor 530 is set to correspond to the position of the second temperature sensor 540. It is located at a relatively closer distance from the light source unit 110 than the second irradiation range 541' located in the preset area 541, and accordingly, the area of the second irradiation range 541' is the first irradiation range ( 531').

And, as the area of the second irradiation range 541' is larger than the area of the first irradiation range 531', the amount of heat transfer per unit area in the second irradiation range 541' is greater than that of the first irradiation range 531'. is lower than the heat transfer rate per unit area.

Accordingly, in order to cause the same temperature change to occur in the first preset region 531 and the second preset region 541, the processor 140 sets the irradiation time for the second irradiation range 541' to the first irradiation range 541'. It can be adjusted to be longer than the irradiation time for the range 531'. Here, it is assumed that the irradiation time for the second irradiation range 541' is 8 minutes and the irradiation time for the first irradiation range 531' is 3 minutes.

In the case described above, the processor 140 determines the first difference between the temperature measured through the first temperature sensor 530 and the preset temperature, and the temperature measured through the second temperature sensor 540 and the preset temperature. Based on the look-up table in which the correlation between the temperature difference between the second difference value and the time difference between the first irradiation time for the first irradiation range 531' and the second irradiation time for the second irradiation range 541' is stored You can prioritize the scope of your investigation.

For example, the correlation between the temperature difference and the time difference as described above may be organized and stored in the following table.

Referring to Table 1 described above, the horizontal items are the first difference between the temperature measured through the first temperature sensor 530 and the preset temperature, and the temperature measured through the second temperature sensor 540 and the preset temperature. The temperature difference between the second difference values with and is listed in a range of 1 degree Celsius, and the vertical items are the first irradiation time for the first irradiation range 531' and the second irradiation time for the second irradiation range 541'. The time difference between the intervals is listed as a range in units of 1 min.

That is, according to the above-described Table 1, priority is given to the ranges of each temperature difference and each time difference, and the difference between the temperature measured through the first temperature sensor 530 and the predetermined temperature The temperature difference between the first difference value and the second difference between the temperature measured by the second temperature sensor 540 and the preset temperature is 1.5 degrees Celsius, and the first irradiation time for the first irradiation range 531' and the second difference When the time difference between the second irradiation times for the two irradiation ranges 541' is 5 minutes, it may be determined by prioritizing the time difference and determining the order of the irradiation flow.

That is, the first difference between the temperature measured through the first temperature sensor 530 and the preset temperature is 1.5 degrees greater than the second difference between the temperature measured through the second temperature sensor 540 and the preset temperature. Even if it is lower, if the second irradiation time for the second irradiation range 541' is 5 minutes longer than the first irradiation time for the first irradiation range 531', the processor 140 first selects the second irradiation range. It can be calculated as an irradiation line 570 that proceeds with invisible light irradiation on the first irradiation range 531' after irradiating the invisible light on 541'.

Meanwhile, the temperature difference between the first difference between the temperature measured through the first temperature sensor 530 and the preset temperature and the second difference between the temperature measured through the second temperature sensor 540 and the preset temperature 6.2 degrees Celsius, and the time difference between the first irradiation time for the first irradiation range 531' and the second irradiation time for the second irradiation range 541' is 5.5 minutes, according to the above-mentioned Table 1, priority is given to the temperature difference. It can be determined by determining the order of the investigation flow by placing a rank.

That is, the first difference between the temperature measured through the first temperature sensor 530 and the preset temperature is 6.2 degrees higher than the second difference between the temperature measured through the second temperature sensor 540 and the preset temperature. If C is lower, even if the second irradiation time for the second irradiation range 541' is longer than the first irradiation time for the first irradiation range 531' by 5.5 minutes, the processor 140 performs the first irradiation time. After irradiating the invisible light to the range 531', the second irradiation range 541' can be calculated as the irradiation line 560 that proceeds to irradiate the invisible light.

In this way, the processor 140 determines the priority of the relative temperature difference between the difference values between each temperature sensor and the preset temperature and the relative time difference between the irradiation times, and sets the temperature difference as the priority and calculates the irradiation route or calculates the time difference. You can set it as a priority and decide whether to calculate the investigation flow.

On the other hand, when the temperature measured by the first temperature sensor 530 and the second temperature sensor 540 is measured below the predetermined temperature, the temperature corresponding to the first temperature sensor 530 and the second temperature sensor 540, respectively, is measured. In the process of determining the irradiation line between the first preset area 531 and the second preset area 541, when the temperature measured through the third temperature sensor 550 is additionally measured below the preset temperature, the processor ( 140), as described above, each of the first temperature sensor 530, the second temperature sensor 540, and the third temperature sensor 550 determines the first difference value, the second difference value, and the third difference value from the preset temperature. The first predetermined area ( 531), an irradiation movement line for an irradiation trajectory between the second preset area 541 and the third preset area 551 may be calculated.

For example, the processor 140, through the above-described process, proceeds from the first investigation range 531' -> the third investigation range 551' -> the second investigation range 541' as shown in FIG. 5B. The irradiation flow 580 may be calculated, and of course, such an irradiation flow may be changed according to calculation conditions.

Meanwhile, the processor 140 may control a predetermined distance between the light source unit 110 and the reflector 120 to control the area and heat transfer rate of the non-visible ray irradiation range for the predetermined area.

Here, the preset distance means the focal length, that is, the processor 140 adjusts the focal distance between the light source unit 110 and the reflector 120 to widen the area of the irradiation range of the invisible light to the preset area. The heat transfer rate can be controlled by adjusting the heat transfer amount per unit area accordingly.

6 is a diagram for explaining an effect according to focal distance control according to an embodiment of the present invention.

Referring to FIG. 6 , the distance 610 between the light source unit 110 and the reflector 120 shown on the left side is greater than the distance 620 between the light source unit 110 and the reflector 120 shown on the right side. As shown on the left, the invisible light generated from the light source unit 110 is reflected by the reflector 120 and irradiated in a forward direction 630 in a straight line, while as shown on the right, from the light source unit 110 It can be seen that the generated invisible light is reflected by the reflector 120 and irradiated in a diagonal direction 640 .

This is because the distance 610 between the light source unit 110 and the reflector 120 shown on the left coincides with the focal length that is in focus, and the distance 620 between the light source unit 110 and the reflector 120 shown on the right side. ) is the out-of-focus focal length.

Here, the processor 140 adjusts the distance between the light source unit 110 and the reflector 120 so that the invisible light is straight for a certain area and the irradiation angle is 90 degrees, or in a diagonal direction so that the irradiation angle is It is possible to control whether or not to irradiate to 30 to 60 degrees, and the area of the irradiation range can be widened or narrowed according to the difference in the irradiation angle.

In addition, by controlling the amount of heat transfer per unit area through the area of the irradiation range, it is possible to control even the degree of heat transfer.

For example, when a person passes or stops where the irradiation range of the light source unit 110 is located, the processor 140 adjusts the distance between the light source unit 110 and the reflector 120 so that the area of the irradiation range and the heat transfer rate are reduced. can be controlled so that people are not affected by heat transmitted through invisible light.

Meanwhile, in the present invention, it is described that when the processor 140 moves the light source unit 110, the reflector 120 coupled with the light source unit 110 also moves in the same direction, but the light source unit 110 moves while the reflector 120 is fixed. ) may be moved to adjust the focal length of the light source unit 110 within the reflector 120 or the reflection angle at which heat generated from the light source unit 110 is reflected by the reflector 120.

In this case, the reflector 120 is fixed and spaced between the light source unit 110 and the reflector 120 so that only the light source unit 110 moves, or a flexible or elastic material is inserted between the light source unit 110 and the reflector 120. Thus, only the light source unit 110 can move freely.

Meanwhile, the apparatus 100 for removing black ice through radiant heat of invisible rays according to another embodiment of the present invention further includes at least one of a non-contact temperature measuring unit and a camera, and the processor 140 irradiates the light source unit 110. If a subject is detected for a predetermined period of time through at least one of the non-contact temperature measurement unit and the camera, irradiation of the light source unit may be stopped.

Referring to FIG. 7 , the apparatus 100 for removing black ice through radiant heat of invisible rays according to another embodiment of the present invention may further include a camera 150, and the processor 140 may include a If a subject is detected for a predetermined time through the camera 150 during irradiation, irradiation of the light source unit 110 may be stopped.

For example, if a person or animal is detected within a preset range for a certain period of time in a video or image obtained through the camera 150, the processor 140 may cause a burn. The investigation of (110) can be automatically stopped.

At this time, the processor 140 may detect and recognize a moving subject such as a person or animal by performing object recognition filtering on the video or image acquired through the camera 150, and the moving state and moving path of the recognized subject. It is possible to determine whether to stop irradiation of the light source unit 110 by determining.

On the other hand, the black ice removal device 100 through radiant heat of invisible rays of the present invention may include a non-contact temperature measuring unit 170 instead of the above-described camera.

As will be described later in FIG. 9 below, the non-contact temperature measurement unit 170 is connected to a partial region of the reflector, and thus can move in the same direction as the direction in which the reflector 120 moves.

In addition, the non-contact temperature measurement unit 170 moves according to the movement of the reflector 120, so that non-contact temperature measurement is possible for the irradiation range of the reflector 120.

In addition, the processor 140 may detect a subject based on temperature information measured by the non-contact temperature measuring unit 170 . Specifically, the processor 140 determines whether the temperature belongs to a temperature range corresponding to a person or an animal based on the temperature of various objects measured through the non-contact temperature measuring unit 170. By making the determination, the detected subject may be recognized.

Here, temperature ranges corresponding to various subjects, such as a temperature range corresponding to humans and a temperature range corresponding to animals, are stored as data in a memory, and the processor 140 measures the temperature measured through the non-contact temperature measuring unit 170. The subject may be recognized by comparing and matching the temperature ranges corresponding to various subjects.

In addition, the processor 140 may determine whether to stop irradiation of the light source unit 110 by determining the moving state and the moving path of the subject recognized through the non-contact temperature measuring unit 170 .

As described above, the processor 140 may detect a subject based on the temperature information measured through the non-contact temperature measuring unit 170 or the camera 150 or the obtained image information, and the light source unit for the detected subject ( 110) may decide whether to discontinue the investigation.

8 is a diagram showing the configuration of a black ice removal device through radiant heat of invisible rays according to another embodiment of the present invention.

Referring to FIG. 8 , the apparatus 100 for removing black ice through radiant heat of invisible rays according to another embodiment of the present invention may further include a temperature/humidity sensor 160, and the processor 140 may It is possible to control the light source unit 110 by automatically determining whether to irradiate the light source unit 110 based on the temperature and humidity information acquired through the humidity sensor 160 .

For example, the processor 140 satisfies the invisible light irradiation condition of the light source unit 110 when the temperature is 2 degrees or less and the humidity is 90% or more through the temperature and humidity information acquired through the temperature/humidity sensor 160. It is determined that the light source unit 110 is automatically turned on and controlled to irradiate invisible light to a predetermined area.

Meanwhile, the processor 140 may generate and provide information on whether the light source unit 110 is irradiated based on big data including geographical characteristics, weather, temperature, and humidity information for each region.

For example, by selecting an area that meets the black ice generation conditions in consideration of topographical characteristics and weather, and predicting the temperature and humidity that meet the black ice generation conditions based on the seasonal weather of the selected area, the present invention is performed in advance. The black ice removal device 100 through radiant heat of invisible light according to an embodiment of the present invention may be disposed in a selected area.

Predictable.

9 is a diagram showing an embodiment of a black ice removal device through radiant heat of invisible rays according to an embodiment of the present invention.

Referring to FIG. 9, a front view of the black ice removal device 100 through radiant heat of invisible light according to an embodiment of the present invention is shown, and a reflector 120 in the form of a parabolic mirror around the light source unit 110. ) is coupled, a support including an actuator is disposed below it, and a processor 140 is disposed inside the support.

Also, a camera 150 and a temperature/humidity sensor 160 may be disposed on both side surfaces of the support, and a non-contact temperature measuring unit 170 may be provided in a partial area outside the reflector 120 .

Here, the non-contact temperature measurement unit 170 is connected to the reflector 120, so that it moves in the same way as the reflector 120 moves, and accordingly, the temperature is measured in real time for the irradiation range of the reflector 120. It becomes possible.

Specifically, the processor 140 continuously measures the temperature on the road surface before irradiation of invisible rays by the light source unit 110 and the temperature on the road surface after irradiation of invisible rays by the light source unit 110 through the non-contact temperature measuring unit 170, It is possible to obtain information on the temperature of the upper phase, and accordingly, to obtain more accurate temperature change by acquiring both the temperature information of the inside of the road surface and the surface of the road surface along with the information obtained from the temperature sensor buried inside the road surface, and based on this, accurate temperature change is obtained. The irradiation range and irradiation time of radiant heat through invisible light can be set.

In addition, when a plurality of temperature sensors buried inside the road surface are installed at a long distance from each other, the area of the road surface that can be measured by one temperature sensor is inevitably limited, so that only the temperature sensor buried in the road surface is part of the road surface. Accurate temperature measurement over the entire area may be difficult.

At this time, the processor 140 may accurately measure the temperature in real time for an area that cannot be measured with a temperature sensor buried in the road surface or an area that is not accurately measured through the non-contact temperature measuring unit 170, and through this, accurate temperature measurement is possible.
