The image captured by the first camera module 130 is transmitted to the user in real time, and the user can control the flight of the drone unit 110 while viewing the image.

The meter reading module 140 is coupled to the gimbal 120 so as to be detachable and attachable, and irradiates light toward a river to identify contaminants during flight, and detects a reaction thereto. The meter reading module 140 may be coupled through the gimbal 120 to prevent performance degradation due to vibration and shaking. The meter reading module 140 may control the direction and angle of light irradiation, and the type of light according to the user's control during flight.

Specifically, the meter reading module 140 irradiates light to an observation point during flight of the drone unit 110 and acquires information on received light in response thereto. The meter reading module 140 may acquire at least one of color information and spectrum information of the received light. To this end, the meter reading module 140 may include a laser module 142, an ultraviolet module 144, and a first sensing module 146.

The laser module 142 may irradiate white laser light. Therefore, the laser module 142 may be utilized as a lighting means for observing the surrounding environment during night flight in addition to checking pollutants. In addition, the laser module 142 may irradiate visible light of a specific color. Visible light of a specific color can be used to identify contaminants.

The first sensing module 146 senses a response to the laser light irradiated to the river. Specifically, the first sensing module 146 acquires color information on the received light received in response to the laser light irradiated to the river. The first sensing module 146 may be a camera module that acquires image data. The first sensing module 146 may acquire image data by photographing an area to which the laser light is irradiated. The first sensing module 146 can capture a high-resolution image of an HD level or higher, so that contaminants can be checked at a high altitude of about 100 meters or more. The image data acquired by the first sensing module 146 may be transmitted to a server connected to a network and analyzed in real time. When fluorescence is detected in the image data, it can be seen that contaminants are present at the corresponding location. The laser module 142 and the first sensing module 146 may operate toward the same region in synchronization with each other.

The meter reading module 140 may further include a second sensing module 148. The second sensing module 148 detects light and acquires spectral information. When light is irradiated onto a pollutant, received light having a wavelength different from that of the irradiated light is emitted. The second sensing module 148 detects the received light and acquires spectrum information. The Raman signal is included in the spectrum information of the received light, and the contaminant component can be identified using this. The second sensing module 148 may sense at least one of a laser light irradiated from the laser module 142 and a received light for ultraviolet light irradiated from the ultraviolet module 144.

Specifically, at least one of laser light and ultraviolet rays is irradiated, and in response thereto, one of received color information and spectrum information is obtained.

First, the meter reading module 140 acquires color information of the received light through the first sensing module 146. The first sensing module 146 may be a camera module capable of obtaining image data. The first sensing module 146 may acquire image data for a laser light and an ultraviolet irradiation area. The presence of contaminants may be checked through image analysis of the irradiation area acquired by the first sensing module 146. When fluorescence is detected in the image data, it can be seen that contaminants are present. The image data is transmitted to the server, and fluorescence can be detected in real time through image analysis using the server's powerful computing resources.

FIG. 2 shows an embodiment of the laser module 142 shown in FIG. 1.

Referring to FIG. 2, the laser module 200 includes a laser diode 210, a phosphor module 220, a first optical module 230, a heat sink 240, and a cooling fan 250.

The laser diode 210 is a semiconductor laser and outputs laser light. The laser light may be visible light of a specific color. In addition, the laser has very high coherence and good directivity or straightness. Because of this, the laser light does not spread and can travel far in parallel even with thin light. Since the light of a light with little straightness spreads easily, the intensity of the light decreases sharply as you move away from the bulb. On the other hand, laser light hardly decreases the intensity of light no matter how far the laser light is. For this reason, a high-flying drone uses a laser diode to check for contaminants by irradiating visible light.

The phosphor module 220 includes a fluorescent material and serves to absorb and emit laser light output from the laser diode 210. The phosphor module 220 may be a YAG phosphor having YAG (yttrium-aluminum-garnet) as a receptor material.

As the laser diode 210, a blue laser diode may be used. In this case, when the blue light of the laser diode 210 is irradiated onto the fluorescent material of the phosphor module 220, the blue light and light of different colors emitted by the excited fluorescent material are combined to generate and output white light 232. Accordingly, the laser module 200 can irradiate white laser light.

The first optical module 230 is a configuration for irradiating the white laser light output from the phosphor module 220 in a desired shape and direction. The first optical module 230 may be a light distribution lens having a beam angle of 10° or less.

The heat sink 240 and the cooling fan 250 reduce heat of the laser module 200 by facilitating dissipation and discharging of heat generated during operation in the laser diode 210 and phosphor module 220. The heat sink 240 is made of a material having good thermal conductivity, such as copper or aluminum, and takes a structure in which the surface area is increased in favor of heat dissipation. The cooling fan 250 is attached to the rear side of the heat sink and rotates the fan to dissipate heat radiated from the heat sink to the outside. Since the laser diode 210 and the phosphor module 220 are one of the components that generate high heat, the heat sink 240 and the cooling fan 250 are used to discharge internal heat during operation, thereby reducing performance deterioration of the laser module 200. prevent.

The laser module 200 may further include an optical filter 260. The white light 232 is output from the first optical module 230, by disposing the optical filter 260 on the object side of the first optical module 230 and controlling the optical filter 260 according to the needs of the user. The white light may be output as it is, or only visible light of a characteristic color may be selectively output. There may be a plurality of optical filters 260. Specifically, the optical filter 260 may include a blue filter that outputs only blue light (450 nm to 490 nm) and a yellow filter that outputs only yellow light (550 to 590 nm).

3 shows an embodiment of the second sensing module 148 shown in FIG. 1.

Referring to FIG. 3, the sensing module 300 is a second optical module 310. It includes an optical sensor unit 320, an amplification unit 330 and a detection unit 340.

Contaminant identification using the present invention finds out the type of molecule based on the phenomenon of absorbing energy as much as the difference in the energy level of electrons of the molecule when light is emitted on a specific molecule. That is, a Raman scattering phenomenon that changes the wavelength of light when light is irradiated onto a material is used. Specifically, the difference (Raman shift) between the energy of the received light and the energy of the irradiated light is measured. Raman shift refers to the vibrational frequency of a molecule.

The second optical module 310 receives the received light 315 generated in response to the light irradiated toward the river during flight. The received light 315 may be generated as a Raman scattering phenomenon in material molecules existing in the river. The second optical module 310 may include a condensing lens that collects the received light 315 and focuses it on the optical sensor unit 320.

The optical sensor unit 320 senses the light that has passed through the second optical module 310, detects the intensity of light for each wavelength, and converts it into an electric signal. The optical sensor unit 320 may include a diffraction element for separating a path of light by wavelength. The optical sensor unit 320 may include a plurality of charge-coupled device (CCD) arrays, which are sensors for converting light into electric charges to obtain an image. Light can be converted into an electrical signal through a plurality of charge coupled device (CCD) arrays. The optical sensor unit 320 may acquire a spectrum, which is information on the intensity of light for each wavelength. The spectrum may be a Raman spectrum according to Raman spectroscopy. The Raman spectrum appears as a band according to frequency or as a peak for a specific wavelength or wave number.

The amplification unit 330 amplifies the electrical signal generated by the optical sensor unit 320 and transmits the amplified electrical signal to the detection unit 340.

The detection unit 340 detects a Raman signal inherent to a substance molecule. Substance analysis may be performed by a server using the detected Raman signal. The Raman signal provides information about the energy according to the vibration mode of a molecule or crystal. When light with a certain wavelength is irradiated on a substance, light is scattered, and most of the scattered light is a signal corresponding to the wavelength of the irradiated light, but some are the position corresponding to the frequency of the vibration mode of the substance at the wavelength of the irradiated light. There is a signal that is shifted (Raman shift). Analysis of this signal reveals information about the morphology and symmetry of the molecule or crystal.

Figure 4 shows a water pollution monitoring method using a drone according to an embodiment of the present invention.

4, the water pollution monitoring method using a drone according to an embodiment of the present invention includes a drone unit flight step (S410), a high altitude patrol step (S420), a pollutant check step (S430), a flight altitude descent step ( S440) and a low hole analysis step (S450).

The drone unit flight step (S410) is a step in which a drone is floated in the air to monitor water pollution and moves to an observation point. In the case of rivers, it is effective to monitor the water quality by flying mainly around the point where the tributaries merge. Therefore, the method of monitoring water pollution using a drone according to an embodiment of the present invention can be performed at the main pollution starting points such as domestic sewage, industrial water, and rainwater inlet of a river. In addition, the drone monitors or monitors water pollution at the point where the tributaries merge, and when pollutants are identified, the drone can check the pollutant emission source by checking the pollutants while climbing along the tributaries.

In the high altitude patrol step (S420), after the drone arrives at an observation point to be monitored, the presence of pollutants is confirmed in earnest. While flying at a relatively high altitude that is not affected by obstacles, check whether the river is polluted with water. For example, while flying at an altitude of 100 to 150 m, light is irradiated into the river, and the reaction is sensed to check the presence of contaminants. Specifically, at the first altitude, light is irradiated to an observation point, and color information on received light is obtained in response thereto.

Checking the pollutant (S430) is a step of checking the presence of the pollutant. Contaminants are identified by checking the color information of the received light. Specifically, contaminants can be identified through whether or not fluorescence is detected by analyzing image data containing color information on the received light. If fluorescence is detected, it can be assumed that the contaminant is present.

The flight altitude lowering step (S440) is a step of lowering the flying altitude of the drone for detailed analysis when pollutants are sensed by the light irradiated in the high altitude patrol step (S420).

The low-air precision analysis step (S450) is a step of irradiating light while flying at a low altitude above a location where a contaminant is found, and sensing a response thereto. For example, during high altitude patrols, light is irradiated to the river while flying at a low altitude of 5 to 10 m from the location where the pollutant was found, and the reaction to it is sensed to check the identity of the pollutant. Specifically, at a second altitude lower than the first altitude, light is irradiated to an observation point, and spectral information on received light is obtained in response thereto.

The method for monitoring water pollution using a drone according to an embodiment of the present invention includes a high altitude patrolling step of checking the presence or absence of pollutants using light at a high altitude, and a high altitude patrol step of checking the presence or absence of pollutants using light at a low altitude. By applying a two-stage analysis method including a low-pore precision analysis step, it is possible to monitor water pollution in a river in real time with a simpler method using a drone.

5 shows an embodiment of a water pollution monitoring method using the drone shown in FIG.

5, the water pollution monitoring method using a drone according to an embodiment of the present invention is a drone unit flight step (S510), a step of obtaining an image by irradiating laser light at a first altitude (high altitude) (S520 ), checking whether fluorescence is detected in the image data (S530), and descending to a second altitude (low altitude) when fluorescence is detected in the image data (S540). It includes the step (S550) of obtaining spectral information by irradiating ultraviolet rays or the like.

The drone unit flight step (S510) is a step in which a drone is floated in the air to monitor water pollution and moves to an observation point. In the case of rivers, it is effective to monitor the water quality by flying mainly around the point where the tributaries merge. At night, while the drone 100 for monitoring water quality is moving to an observation point for monitoring water pollution, the white light of the laser module 132 may be used as illumination.

In the step of obtaining an image by irradiating laser light at a first altitude (high altitude) (S520), after arriving at the observation point, while flying at a relatively high altitude, for example, 100 to 150 m, the laser light is irradiated to the river, This is a step of taking an image of the laser light irradiation area. The step of obtaining the image (S530) is performed using the first meter reading module 130 coupled to the drone 100 for monitoring water quality according to an embodiment of the present invention shown in FIG. 1. In an embodiment of the step of acquiring the image (S530), the laser module 142 sequentially irradiates white, blue, and yellow laser light, and the laser light of each color through the first sensing module 144 Reactive pollutants can be identified.

The captured image data is transmitted to the server so that image analysis can be performed in real time. Image analysis is an operation to check whether fluorescence is detected in image data. If fluorescence is detected, it is recognized that contaminants are present at the location. Video analysis is automatically and quickly analyzed by applications installed on the server, utilizing the server's powerful computing resources.

The step of descending to the second altitude (low altitude) (S540) is a step of lowering the flight altitude of the drone to a second altitude lower than the first altitude. If fluorescence is detected as a result of the previous image analysis, it is recognized that contaminants are present, and the flight altitude of the drone is lowered for more precise analysis.

In the step of obtaining spectral information of the received light by irradiating ultraviolet rays (S550), after confirming the presence of a contaminant at a first altitude, a detailed analysis is performed at a second altitude lower than the first altitude. This is the step to confirm identity. For example, during high altitude patrols, light is irradiated to the river while flying at a low altitude of 5 to 10 m from the location where the pollutant was found, and the reaction to it is sensed to check the identity of the pollutant. Specifically, spectrum information of received light is obtained by irradiating at least one of ultraviolet rays or visible light of a specific color to the corresponding region. In an embodiment, ultraviolet B and ultraviolet C are irradiated through the ultraviolet module 142 coupled to the water quality monitoring drone 100 shown in FIG. 1, and blue and yellow laser light is emitted through the laser module 132. You can investigate. The obtained spectrum information is transmitted to the server, and the contaminant can be quickly identified using the pollutant spectrum database.

After obtaining the spectral information, a step (S560) of confirming the identity of the pollutant is performed. The wavelength of light irradiated to the pollutant and the wavelength of the light received by the pollutant become different (Raman scattering). This is an intrinsic characteristic due to the molecular structure of a substance, and the degree to which the wavelength is different depends on the type of substance. Therefore, it is possible to confirm the contaminant component depending on how different the irradiated wavelength and the wavelength of the received light are.

If it is confirmed that it is not a contaminant as a result of the analysis of the spectral information, it rises to the first altitude again, and a high altitude patrol using laser light is performed. If it is identified as a pollutant as a result of analyzing the spectrum information, monitoring is continuously conducted at the observation point necessary to identify the pollutant emission source, taking into account the flow of river water. Through this process, the spread of water pollution can be prevented early by quickly identifying the pollutant emission source. If necessary, it is possible to secure evidence by photographing the site situation and atmosphere through the camera module 130 coupled to the drone 100 for monitoring water pollution.

The water pollution analysis method using a drone according to an embodiment of the present invention may further include a step (S580) of collecting a sample at a corresponding location when pollutants are present as a result of spectrum analysis. After the drone is dear, it is possible to obtain more accurate and diverse information on contaminants by applying various analysis methods to the sample. Through this, it is possible to accurately and quickly check whether or not the river is polluted with water and pollutants.

6 briefly describes a site for monitoring water pollution in a river using a water quality monitoring drone according to an embodiment of the present invention.

Referring to FIG. 6, a user arrives at the site with a drone for monitoring water pollution along with a server and an analysis kit installed in a vehicle to monitor water pollution. It is effective to set the observation point near the confluence of tributaries. The user moves the drone to the observation point of the river and then performs a high altitude patrol. At an altitude of about 150m, the river is irradiated with laser light to acquire image data about it. Image data is transmitted to a server in the vehicle, and image data analysis is performed in real time. When contaminants are identified in the image data, low altitude analysis is performed by lowering the altitude of the drone. UV rays and visible light of a specific color are irradiated at a low altitude of 5 to 10 m, and spectral information of received light is obtained in response thereto. Spectral information including the Raman signal is transmitted to the server in the vehicle, and the contaminant is quickly identified by referring to the pollutant database. Once a pollutant is identified, it is possible to trace the source of the pollutant by flying against the tributary. If necessary, you can control the drone's flight while moving in a vehicle. In this case, it is possible to control while viewing the image captured by the camera module coupled to the drone in the vehicle. Meanwhile, the user can retake the sample using a drone. The sample collected by the drone is delivered to the user, and analysis is performed using an analysis kit directly on site. Users can monitor water pollution for as long as necessary while replacing the drone's battery on site.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features. You can understand. Therefore, the embodiments described above are illustrative in all respects, and should be understood as non-limiting.
