Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a portable hyperspectral device and method for detecting trace pollutants. Background Art

[0002] Hyperspectral detection is a method in which a hyperspectral imager obtains the spectral reflectance or radiation information of a target object to achieve precise identification and classification of the target object. Compared with traditional multispectral remote sensing technology, a hyperspectral imager has a higher spectral resolution and can obtain richer spectral information, thereby achieving more accurate identification and monitoring of the target object. This feature gives hyperspectral imagers a significant advantage in monitoring trace pollutants.

[0003] Hyperspectral detection of trace pollutants can be used in atmospheric trace pollutant monitoring, water pollution monitoring and soil pollution monitoring. In water pollution monitoring, currently, manual sampling is generally carried out and then returned to the laboratory for testing. This method cannot truly reflect the dynamic distribution of pollutants in the water body; secondly, most of the existing trace pollutant detection instruments are integrated fixed structures, so the detection instrument itself is large in size and poor in convenience, which is not convenient for users to use, repair and replace internal components. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a portable hyperspectral device and method for detecting trace pollutants, which can accurately detect water quality and can be used in different environments to improve accuracy. It is also easy to hold and improves the convenience of detection.

[0005] The present invention solves the above technical problems by the following technical means:

[0006] A portable hyperspectral device for detecting trace pollutants comprises a base structure, a hyperspectral photosensitive component and a handheld component. The hyperspectral photosensitive component is assembled in the base structure for detecting trace pollutants, and the handheld component is assembled on the base structure for driving the base structure and the hyperspectral photosensitive component to move away from the handheld component.

[0007] According to the above-mentioned technical means, through the mutual cooperation of the base structure, the hyperspectral photosensing component and the handheld component, not only can the water quality be accurately detected, but it can also be used in different environments to improve the accuracy, and it is also easy to hold, thereby improving the convenience of detection.

[0008] Furthermore, the base structure includes a shell, a mounting assembly and a driving assembly. The mounting assembly is fixedly mounted in the shell, the hyperspectral photosensitive assembly is mounted at the mounting assembly, and the driving assembly is assembled in the shell and is transmission-connected to the hyperspectral photosensitive assembly for driving the hyperspectral photosensitive assembly to move.

[0009] According to the above technical means, by arranging the installation component and the driving component in the shell, it is beneficial to compactly assemble the hyperspectral photosensing component and drive its movement, which is convenient for use.

[0010] Furthermore, an installation space is provided in the shell, an annular groove is provided in the shell, a rotation area is formed between the annular groove and the installation space for accommodating the motion trajectory of the drive assembly, and a mounting plate is provided on one side of the shell.

[0011] According to the above technical means, by forming an installation space in the shell, it is beneficial to the installation of the hyperspectral photosensitive component, and by forming a rotating area, the movement of the driving component will not be blocked. At the same time, the structure is relatively compact and easy to disassemble and replace.

[0012] Furthermore, the mounting assembly includes an annular seat, which is fixedly connected to the shell, an arc-shaped limiting structure is fixedly arranged inside the annular seat, and a movable area is formed between the outer wall of the annular seat and the shell.

[0013] According to the above technical means, by setting the annular seat and the limiting structure, on the one hand, it is conducive to the stable installation of the hyperspectral photosensitive component, and on the other hand, it is conducive to the movement of the hyperspectral photosensitive component.

[0014] Furthermore, the driving assembly includes a power source and an actuator. The power source is fixedly installed in the shell. One end of the actuator is fixedly connected to the output shaft of the power source, and the other end is located in the shell to drive the hyperspectral photosensing assembly to rotate.

[0015] According to the above technical means, the actuator is driven by a power source, which can drive the hyperspectral photosensor component to rotate in the shell, thereby performing more accurate detection of water quality.

[0016] Furthermore, the hyperspectral photosensing component includes a hyperspectral camera, an RGB camera, a light source and a base. The hyperspectral camera and the RGB camera are both fixedly mounted on the base, and the light source is mounted on a driving component to drive the light source to move.

[0017] According to the above technical means, through the cooperation of hyperspectral cameras and RGB cameras, when ambient light enters the water body, various substances in the water diffusely reflect the light beam. This diffuse reflection spectrum carries the absorption and reflection intensity information of the substance to different bands of spectrum. The direct reflection spectrum of the water surface does not carry the spectral information of the substance. The hyperspectral camera is used to obtain the diffuse reflection spectrum of the water body, and cooperates with the RGB camera to obtain clearer images of various substances in the water body, thereby obtaining clearer composition, quality, grade and other data of the detected water body; and then through the light source, the hyperspectral camera and RGB camera can adapt to different indoor and outdoor environments.

[0018] Furthermore, the handheld assembly includes a fixed seat, a telescopic member and a handle, the fixed seat is assembled on the shell, one end of the telescopic member is rotatably installed in the fixed seat, and the handle is fixedly installed on the free end of the telescopic member.

[0019] According to the above technical means, through the cooperation of the telescopic part and the handle, the operator can use it by hand to detect the water quality in different environments.

[0020] Furthermore, a display screen is provided on the handle, and the display screen is communicatively connected with the hyperspectral photosensing component.

[0021] According to the above technical means, it is convenient for operators to view detection information in real time.

[0022] Furthermore, a light sensor is disposed on the shell, and a controller is disposed in the shell. The controller is electrically connected to the light sensor and the hyperspectral photosensing component.

[0023] According to the above technical means, it is convenient to control the operation of the hyperspectral photosensing component according to the light intensity of different environments, thereby improving practicality.

[0024] The present application also discloses a portable hyperspectral method for detecting trace pollutants. Based on the above-mentioned device, the method comprises the following steps:

[0025] S1. According to the ambient light intensity detection, start the hyperspectral photosensor component and perform detection;

[0026] S2. Analyze the images detected by the hyperspectral photosensitive component, convert them into a spectrum, and then compare them with the standard spectrum;

[0027] S3. Mark the trace pollutants in the compared spectrum and transmit it to the display screen.

[0028] According to the above technical means, the hyperspectral camera and RGB camera are first started according to the light intensity in the external environment, and the working conditions of the light source are controlled to adapt to different environments. Then the detection is carried out, and the detection image is converted into a diffuse reflectance spectrum and compared with the standard spectrum to mark the type of trace pollutants and the excess amount, and transmit them to the display screen for real-time viewing by the operator.

[0029] The present application adopting the above scheme has the following beneficial effects:

[0030] 1. By assembling the hyperspectral photosensitive component in the base structure, it is easy to carry when detecting trace pollutants in water quality, making the detection more convenient; and setting a handheld component on the base structure makes it easier for operators to use and carry, and is also conducive to the detection of different water bodies;

[0031] 2. In this application, the base structure and the handheld component are simple in structure and highly practical, and the light source in the hyperspectral photosensitive component can be rotated according to different usage environments to better adapt to use in different environments;

[0032] 3. The portable hyperspectral device for detecting trace pollutants in the present application can be used not only in outdoor environments but also in indoor environments. When used in indoor environments, the container can be directly used as a detection vessel, and when not in use, it can be used as a cover to seal the hyperspectral camera and RGB camera to avoid damage, and is highly practical.

Therefore, the terms describing the positional relationship in the figures are only used for exemplary description and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances:

[0048] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0049] like Figure 1-7 As shown, the embodiment of the present application discloses a portable hyperspectral device for detecting trace pollutants, including a base structure 1, a hyperspectral photosensitive component 2 and a handheld component 3. The hyperspectral photosensitive component 2 is assembled in the base structure 1 for detecting trace pollutants. The handheld component 3 is assembled on the base structure 1, and is used to drive the base structure 1 and the hyperspectral photosensitive component 2 to move away from the handheld component 3, so as to reach water bodies in different areas for detection, and is also easy to carry, thereby improving the convenience of detection.

[0050] In some embodiments, Figure 2-6 As shown, the base structure 1 includes a housing 11, a mounting assembly and a driving assembly. The mounting assembly is fixedly mounted in the housing 11, and the hyperspectral photosensitive assembly 2 is mounted at the mounting assembly. The driving assembly is assembled in the housing 11 and is transmission-connected to the hyperspectral photosensitive assembly 2 to drive the hyperspectral photosensitive assembly 2 to move. By dividing the base structure 1 into the housing 11, the mounting assembly and the driving assembly, the hyperspectral photosensitive assembly 2 can be easily disassembled and replaced.

[0051] In this embodiment, an installation space 103 is provided in the housing 11 for assembling the installation component and the hyperspectral photosensitive component 2. An annular groove 101 is provided in the housing 11, and a rotation area 102 is formed between the annular groove 101 and the installation space 103 for accommodating the motion trajectory of the drive component. A mounting plate 13 is provided on one side of the housing 11, and the mounting plate 13 is fixed to the annular groove 101 by bolts for closing the installation space 103. A cover 12 is fixedly installed on the outer side of the housing 11 by bolts on the outer side of the mounting plate 13 for closing the outer side of the housing 11.

[0052] In this embodiment, if Figure 6-7 As shown, the mounting assembly includes an annular seat 22, which is elliptical, and the outer wall of the annular seat 22 is fixedly connected to the housing 11 through a connecting plate 23. An arc-shaped limiting structure 221 is fixedly arranged in the annular seat 22, which is used to limit the installation position of the hyperspectral photosensitive component 2 in the annular seat 22 to prevent it from shaking easily. A movable interval is formed between the outer wall of the annular seat 22 and the housing 11, which is used to enable the hyperspectral photosensitive component 2 to move in the movable space 201.

[0053] In this embodiment, two arc-shaped limiting structures 221 are provided, and they are symmetrically arranged. The two arc-shaped limiting structures 221 are both provided as limiting blocks, and the limiting blocks are formed integrally with the annular seat 22 using elastic plastic material, and can also be formed using plastic or alloy materials with wear resistance. In order to avoid hard contact between the hyperspectral photosensitive component 2 and the limiting blocks, a gasket 222 such as a sponge pad can also be provided between the limiting blocks and the hyperspectral photosensitive component 2.

[0054] In this embodiment, if Figure 4 As shown, there is a height difference between the annular groove 101 and the installation space 103, thereby forming a rotation area 102, so that the driving component can rotate in the rotation area 102, thereby driving the hyperspectral photosensitive component 2 to rotate in the movable range. The annular seat 22 is fixedly connected to the housing 11 through the connecting plate 23, so that the annular seat 22 and the hyperspectral photosensitive component 2 can be stably installed in the housing 11.

[0055] In this embodiment, if Figure 7As shown, the hyperspectral photosensitive component 2 includes a hyperspectral camera 24, an RGB camera 25, a light source 26 and a base 21. The hyperspectral camera 24 and the RGB camera 25 are both fixedly mounted on the base 21 by bolts. The hyperspectral camera 24 is used to perform spectral scanning on the water body and generate an image data cube containing multiple spectral band information. The RGB camera 25 is used to capture images and spectral information within the visible light range. When the ambient light enters the water body, various substances in the water diffusely reflect the light beam. This diffuse reflection spectrum carries the absorption and reflection intensity information of the substance to different bands of the spectrum. The direct reflection spectrum on the surface of the water body does not carry the spectral information of the substance. The hyperspectral camera 24 is used to obtain the diffuse reflection spectrum of the water body, and cooperates with the RGB camera 25 to obtain a clearer image of each substance in the water body, thereby obtaining clearer composition, quality, grade and other data of the detected water body, so as to detect trace pollutants in the water body. The light source 26 is installed on the driving component to drive the light source 26 to move. By setting the light source 26, the brightness of the light source 26 can be adjusted according to the light intensity of different environments, so that the hyperspectral camera 24 and the RGB camera 25 can adapt to different indoor and outdoor environments and are more convenient to use.

[0056] In this embodiment, a camera seat 251 is further provided between the RGB camera 25 and the base 21. The camera seat 251 is fixedly mounted on the bottom plate, and the RGB camera 25 is fixedly mounted on the camera seat 251 by bolts. To enhance the protection of the hyperspectral camera 24, a flexible pad is provided between the hyperspectral camera 24 and the base 21. Of course, in actual situations, other cameras that can detect trace pollutants in water bodies can also be selected.

[0057] In this embodiment, if Figure 5-7 As shown, the driving assembly includes a power source 131 and an actuator. The power source 131 is fixedly mounted on the mounting plate 13 by bolts. One end of the actuator is fixedly connected to the output shaft of the power source 131, and the other end is located in the rotation area 102, which is used to drive the light source 26 in the hyperspectral photosensitive component 2 to rotate, so as to provide better lighting conditions according to the light intensity conditions in different environments, so as to improve the accuracy of water quality detection.

[0058] In this embodiment, the actuator includes an actuator arm 15, which is located on the annular seat 22. One end of the actuator arm 15 is fixedly connected to the output shaft of the power source 131 through a spline, and is used to drive the actuator arm 15 to rotate along the elliptical annular seat 22. A sliding groove 151 is provided on the actuator arm 15, and a connecting bracket 261 is fixedly provided on the light source 26. The connecting bracket 261 passes through the sliding groove 151, and a sliding plate 153 is rotatably provided on the connecting bracket 261 on the sliding groove 151, so that when the actuator arm 15 drives the light source 26 to move along the annular seat 22, the connecting bracket 261 can slide along the sliding groove 151, thereby adapting to the elliptical motion track.

[0059] In this embodiment, to prevent the connection bracket 261 from being separated from the sliding slot 151 , blocks are integrally formed at both ends of the sliding plate 153 , and the actuator arm 15 is provided with moving slots 152 on both sides of the sliding slot 151 , and the blocks are located in the moving slots 152 .

[0060] In this embodiment, in order to make the rotation of the light source 26 smoother, a bearing is provided at the connection between the connecting bracket 261 and the sliding plate 153. The light source 26 can be set as a lamp similar to sunlight, and a suitable light source 26 can be selected according to actual conditions. By setting the light source 26 separately from the hyperspectral camera 24 and the RGB camera 25, but the light source 26 rotates around the axis of the hyperspectral camera 24 and the RGB camera 25, better illumination can be provided for the hyperspectral camera 24 and the RGB camera 25.

[0061] In this embodiment, a light sensor is provided on the housing 11 for sensing the external light intensity. A controller 14 is provided on the mounting plate 13, and the controller 14 is connected to the light sensor, the hyperspectral camera 24, the RGB camera 25, the power source 131 and the light source 26 for controlling the opening and closing of the light source 26 and the light intensity according to the light intensity sensed by the light sensor, and can also control the operation of the hyperspectral camera 24, the RGB camera 25 and the power source 131.

[0062] In this embodiment, the hyperspectral camera 24, the RGB camera 25 and the light source 26 are separately arranged, which is convenient for replacement and disassembly, and is simple and practical. The power source 131 can be set as a servo motor, a reduction motor, etc.

[0063] In some embodiments, Figure 3-4 As shown, the housing 11 is provided with a container 16 on one side of the output end of the hyperspectral camera 24, the RGB camera 25 and the light source 26. When the entire device is not in use, the container 16 can be snapped onto the housing 11 to enclose the hyperspectral camera 24, the RGB camera 25 and the light source 26. On the one hand, the hyperspectral camera 24, the RGB camera 25 and the light source 26 can be protected, and on the other hand, the entry of debris can be prevented. When the entire device is used outdoors, in order to prevent the container 16 from being lost or to make it easier to carry, a connecting rope can be provided on the side wall of the container 16 and the side wall of the housing 11.

[0064] When the device is used indoors, in order to improve the utilization rate of the container 16, a mirror coating can be provided at the bottom of the container 16, so that the container 16 can be used as a detection vessel when it is indoors, and can accommodate the sampled water quality. The mirror coating can improve the reflectivity, so that when the light source 26 is in use, the hyperspectral camera 24 and the RGB camera 25 can receive more diffuse reflection information, so as to more accurately detect the trace pollutants in the sampled water quality. In order to further improve the reflectivity, a mirror coating can also be provided on the inner wall of the container 16. In actual situations, the mirror coating can be plated on the container 16 by vacuum coating, vacuum sputtering, electroplating, chemical deposition, etc. The mirror coating can be a nickel layer, a chromium layer, a silver layer, etc., and a suitable coating can be selected according to actual conditions.

[0065] In order to facilitate the sampled water quality, scale lines can be set on the outer wall of the container 16 to facilitate observation of the water quality in the container 16. The material of the container 16 can be a transparent material with a certain strength such as quartz glass and tempered glass, and a suitable transparent material or non-transparent material can be selected according to actual conditions.

[0066] In some embodiments, Figure 1-2 As shown, the handheld component 3 includes a fixed seat 31, a telescopic member 32 and a handle 33. The fixed seat 31 is assembled on the housing 11, and one end of the telescopic member 32 is rotatably installed in the fixed seat 31, which is used to drive the base structure 1 and the hyperspectral photosensitive component 2 to move away from the handle 33, thereby increasing the detection range and making it more convenient to hold the device in hand. The handle 33 is fixedly installed at the free end of the telescopic member 32, so that the operator can hold the device in hand.

[0067] In this embodiment, the telescopic member 32 can be set as an electric telescopic rod, or a telescopic cylinder, etc., or a suitable device with a telescopic function can be selected according to actual conditions. Preferably, it is an electric telescopic rod, one end of which is rotatably mounted in the fixed seat 31 through a rotating shaft, and the rotating shaft and one end of the telescopic rod have a large friction force, so that the base structure 1 and the hyperspectral photosensitive component 2 can maintain stability after rotating a certain angle. Of course, in actual conditions, the relative angle between the base component and the telescopic member 32 can also be controlled by setting a motor at the rotating shaft.

[0068] In this embodiment, the handle 33 is fixed to the free end of the electric telescopic rod by bolts, and a display screen 34 is provided on the handle 33. The display screen 34 is communicatively connected with the hyperspectral camera 24 and the RGB camera 25. When the hyperspectral camera 24 transmits the spectrum of trace pollutants detected in the water body to the display screen 34, the operator can intuitively view the detection results of trace pollutants in the water body through the display screen 34.

[0069] In this embodiment, when the telescopic member 32 is not needed, it can be stored in the fixing seat 31, which is more convenient to carry; the fixing seat 31 can also be provided with a wristband connected by a rope, which can be put on the wrist of the operator.

[0070] In some embodiments, in order to make the angle of the base structure 1 on the fixing seat 31 adjustable, a connecting shaft can be set between the housing 11 and the fixing seat 31, and the housing 11 can be manually rotated to adjust the relative angle between the base structure 1 and the hyperspectral photosensitive component 2 on the fixing seat 31, so as to achieve adjustable detection orientation and a larger detection range. Of course, a motor can also be set on the connecting shaft to automatically control and adjust the relative angle between the two.

[0071] In this embodiment, a power button is provided on the housing 11 for controlling the start and shut down of the entire device.

[0072] like Figure 8 As shown, the embodiment of the present application also discloses a method for detecting trace pollutants using a portable hyperspectral method, comprising the following steps:

[0073] S1. According to the light sensor detecting the ambient light intensity, comparing it with the preset value, determining whether to turn on the light source 26, then starting the hyperspectral photosensitive component 2, and detecting the water body;

[0074] S2. Analyze the image detected by the hyperspectral photosensitive component 2, convert it into a spectrum, and then compare it with the standard spectrum;

[0075] S3. Mark the trace pollutants on the compared spectrum and transmit it to the display screen 34.

[0076] In some optional implementations, in step S1, when it is detected that the ambient light intensity is greater than or equal to a preset value, the light source 26 is turned off. When it is detected that the ambient light intensity is less than the preset value, the light source 26 is turned on.

[0077] It can be understood that the preset value is set based on the ability of the hyperspectral camera 24 to capture a clear picture of the water body. When the light source 26 is turned on, the intensity of the light source 26 is adjusted according to the ambient light intensity.

[0078] It can be understood that when the hyperspectral photosensing component 2 is started, the hyperspectral camera 24 and the RGB camera 25 are started at the same time, and the intensity of the light source 26 is adjusted according to the current environment, and the relative positions of the light source 26 and the hyperspectral camera 24 and the RGB camera 25 are adjusted so that the hyperspectral camera 24 and the RGB camera 25 can obtain a clearer picture.

[0079] In some optional embodiments, in step S2, when the image detected by the hyperspectral photosensitive component 2 is analyzed, the type and content of trace pollutants in the water body are mainly analyzed and converted into a diffuse reflectance spectrum, which is then compared with the standard diffuse reflectance spectrum pre-stored in the hyperspectral camera 24 to compare the type and quantity of trace pollutants.

[0080] In some optional embodiments, in step S3, the types and quantities of trace pollutants in the diffuse reflectance spectrum that exceed the standard values ​​are marked and transmitted to the display screen 34, so that the operator can view the detected trace pollutants.
