Description

Technical Field

[0001] The present invention relates to the technical field of insecticide substitutes, and particularly to a multi-mode combined mosquito collection system for small water bodies. Background Art

[0002] In the prior art, there are significant technical limitations in mosquito collection devices: firstly, a single attracting source (relying only on light attraction or chemical attractants) leads to low efficiency in the directional capture of target organisms; secondly, the device lacks the ability to regulate environmental adaptability and cannot achieve intelligent switching of working modes by sensing the distribution characteristics of floating objects on the water surface. These two defects severely restrict the actual application efficiency of the device in complex ecological environments.

[0003] Chinese Patent Publication No.: CN112790174B discloses a timed mosquito collection device, including: a housing, a mosquito attracting lamp, a trapping agent containing unit, a trapping agent adding unit, a mesh, a camera, a fan, a turntable, and a base. A central control module is arranged inside the base, and the central control module is used to control the working process of the timed mosquito collection device. When the device starts to work, the central control module can set the trapping agent and the types of lights with different wavelengths according to the types of mosquitoes to be trapped. The central control module sets the mosquito density in the device according to the type of trapping agent, and sets the fan speed according to the mosquito density in the device. The central control module adjusts the preset mosquito density in the device according to the density detection time interval, and corrects the preset mosquito density in the device after adjustment according to the amount of trapping agent added. The central control module controls the camera to repeatedly detect the change in the mosquito density in the device within the density detection time interval, and adjusts the fan speed, the brightness of the mosquito attracting lamp, and the amount of trapping agent added according to the detected mosquito density. It can be seen that the timed mosquito collection device has the problem that it cannot achieve intelligent switching of working modes by sensing the distribution characteristics of floating objects on the water surface. Summary of the Invention

[0004] Therefore, the present invention provides a multi-mode combined mosquito collection system for small water bodies to overcome the problem in the prior art that intelligent switching of working modes cannot be achieved by sensing the distribution characteristics of floating objects on the water surface.

[0005] To achieve the above object, the present invention provides a multi-mode combined mosquito collection system for small water bodies, including a sampling body, and further including:

[0006] A detection module, which is connected to the sampling body, includes an image sensor for collecting the water surface image of a small water body, a temperature sensor for obtaining the air environment temperature above the water body, and a light sensor for obtaining the environmental light intensity;

[0007] A sampling module, which is respectively connected to a sampling body and a detection module, for collecting mosquitoes in small water bodies, including a light wave trapping component that emits modulated light waves in the mosquito-sensitive wavelength band to attract mosquitoes to approach, a carbon dioxide trapping component for generating carbon dioxide, a negative pressure adsorption component for absorbing mosquitoes, and a disturbance component arranged below the negative pressure adsorption component for changing the movement state of mosquitoes;

[0008] A cooperative control module, which is respectively connected to the detection module and the sampling module, for determining the placement position of the sampling module according to the distribution position of floating objects on the water surface, and correcting the placement position according to the corresponding mapping rule between the number of mosquitoes captured at the placement position and the complexity of the floating object structure;

[0009] Determining the type of floating object distribution according to the distribution position of floating objects on the water surface around the placement position, and determining the sampling method according to the type of floating object distribution, including adjusting the direction change frequency of the carbon dioxide outlet, or adjusting the outlet direction of carbon dioxide, or adjusting the spraying pressure of carbon dioxide and the adsorption pressure of the negative pressure adsorption component;

[0010] Among them, the types of floating object distribution include dispersed surrounding type, dispersed non-surrounding type, and aggregation type; the operating state of the disturbance component is determined according to the complexity of the floating object.

[0011] Further, the cooperative control module is also used to respectively obtain the number of mosquitoes captured at the placement position and the complexity of the floating object structure, perform linear regression analysis on the number of mosquitoes captured at the placement position and the complexity of the floating object structure to generate a mapping function between the number of mosquitoes captured at the placement position and the complexity of the floating object structure, and calculate the corrected coordinate amount of the position according to the mapping function to correct the placement position of the sampling module.

[0012] Further, the complexity of the floating object structure is the sum of the product of the number of cracks on the floating object surface and the crack number weight coefficient and the product of the reciprocal of the crack area on the floating object surface and the crack area reciprocal weight coefficient; among them, the sum of the crack number weight coefficient and the crack area reciprocal weight coefficient is 1.

[0013] Further, the cooperative control module is connected to the disturbance component, and is used to start the disturbance component under the condition that the complexity of the floating object structure is greater than the preset complexity.

[0014] Further, the cooperative control module is connected to the image sensor. When the ratio of the total area of the figure formed by the connection line of the floating object distribution edges on the small water body surface to the total water surface area is less than the set ratio, it is determined that the floating object distribution type is the aggregation type, and then the placement position of the sampling body is determined as the geometric center position of the figure; and when the ratio of the total area of the figure formed by the connection line of the floating object distribution edges on the small water body surface to the total water surface area is greater than or equal to the set ratio, it is determined that the floating object distribution type is the dispersion type.

[0015] Further, the dispersion type includes the dispersed surrounding type and the dispersed non - surrounding type.

[0016] Further, the cooperative control module is respectively connected to the carbon dioxide trapping component and the negative pressure adsorption component. Under the condition that the floating object distribution type is the aggregation type and the placement of the sampling body position is completed, it controls the carbon dioxide trapping component to reduce the jet pressure and the negative pressure adsorption component to increase the adsorption pressure.

[0017] Further, the jet pressure is positively correlated with the ratio of the total area of the figure formed by the connection line of the floating object distribution edges on the small water body surface to the total water surface area; the adsorption pressure is negatively correlated with the ratio.

[0018] Further, the cooperative control module is connected to the image sensor. When the floating object distribution type is the dispersion type and the farthest straight - line distance from the floating object distribution point with the farthest straight - line distance from the straight line of the small water body shore in the closed curve formed by the connection line of the floating object distribution edges on the small water body surface is less than or equal to the preset straight - line distance, it is determined that the floating object distribution type is the dispersed surrounding type, and then the placement position of the sampling body is determined to be between the closed curve and the small water body shore, and the cooperative control module controls the carbon dioxide trapping component to adjust the carbon dioxide outlet direction from inside the closed curve to along the tangent direction of the closed curve.

[0019] Further, the cooperative control module is connected to the image sensor. When the floating object distribution type is the dispersion type and the farthest straight - line distance from the floating object distribution point with the farthest straight - line distance from the straight line of the small water body shore in the closed curve formed by the connection line of the floating object distribution edges on the small water body surface is greater than the preset straight - line distance, it is determined that the floating object distribution type is the dispersed non - surrounding type, and then the placement position of the sampling body is determined to be inside the closed curve, and the direction change frequency of the carbon dioxide outlet is increased.

[0020] Compared with the prior art, the beneficial effect of the present invention lies in that, by setting a detection module, a sampling module and a coordinated control module, a light wave trapping component, a carbon dioxide trapping component, a negative pressure adsorption component and a sampling module of a disturbance component arranged on the water surface to change the movement state of mosquitoes, a variety of ways of attracting and catching mosquitoes are combined together, and the placement position of the sampling body is determined according to the type of distribution of floating objects, which solves the problem of low efficiency of catching mosquitoes in existing mosquito catching technologies when dealing with different distribution types of floating objects, and improves the efficiency of the sampling module in catching mosquitoes.

[0021] Furthermore, the placement position is corrected according to the corresponding mapping rule between the number of mosquitoes captured at the placement position and the complexity of the floating object structure, which solves the problem of low efficiency in capturing mosquitoes at the placement position and improves the efficiency of capturing mosquitoes at the placement position.

[0022] Furthermore, the disturbance component can slap and vibrate the water surface, forcing the mosquitoes under the floating object to flee in fear, thus solving the problem that the mosquitoes under the floating object are difficult to be attracted by the light wave trapping component and the carbon dioxide trapping component. The determination of whether to activate the disturbance component is based on the complexity of the structure of the floating object closest to the sampling body, thus overcoming the problem that when the structure of the floating object is relatively simple, the activation of the disturbance component easily causes the mosquitoes to escape, thereby reducing the chance of collection. This ensures that mosquitoes in different positional relationships to the floating object can be attracted by the light wave trapping component and the carbon dioxide trapping component.

[0023] Furthermore, under the condition that the distribution type of the floating objects is the aggregation type and the sampling body is placed, the carbon dioxide trapping component is controlled to reduce the jet pressure and the negative pressure adsorption component is controlled to increase the adsorption pressure, thereby solving the problem that the equipment vibration caused by excessive jet pressure causes the negative pressure adsorption component to vibrate, which causes the negative pressure adsorption range of the negative pressure adsorption component to change, causing the mosquito group to be frightened and flee, and realizing that the carbon dioxide trapping component can still stably attract mosquitoes when a large number of mosquitoes gather; wherein, the negative pressure adsorption component increases the adsorption pressure, improves the adsorption capacity of mosquitoes, and improves the efficiency of catching mosquitoes when a large number of mosquitoes appear.

[0024] Furthermore, by controlling the carbon dioxide trapping component according to the dispersed surrounding type of floating object distribution, the outlet direction of the carbon dioxide is adjusted from within the closed curve to along the tangent direction of the closed curve. Due to the distribution characteristics of the dispersed surrounding type, mosquitoes are more dispersed and do not gather at a central point. Therefore, changing the outlet direction to along the tangent direction of the closed curve can make the outlet gas follow the trajectory of the closed curve, thereby improving the collection efficiency and effectiveness of mosquitoes.

[0025] Further, by determining that the floating object distribution type is dispersed non - surrounding, the placement position of the sampling body is determined to be within the closed curve, and the direction change frequency of the carbon dioxide outlet is increased, reducing the wider distribution position of mosquitoes caused by the scenario of dispersed non - surrounding distribution type. Therefore, by increasing the direction change frequency of the outlet, the collection effectiveness for mosquitoes with irregular and wide distribution is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A detection module, which is connected to the sampling body, includes an image sensor for collecting the water surface image of the small water body, a temperature sensor for obtaining the air ambient temperature above the water body, and a light sensor for obtaining the ambient light intensity;

[0035] A sampling module, which is respectively connected to the sampling body and the detection module, and is used to collect mosquitoes in the small water body, including a light wave trapping component that emits modulated light waves in the mosquito-sensitive band to attract mosquitoes to approach, a carbon dioxide trapping component for generating carbon dioxide, a negative pressure adsorption component for absorbing mosquitoes, and a disturbance component arranged below the negative pressure adsorption component for changing the movement state of mosquitoes;

[0036] A collaborative control module, which is respectively connected to the detection module and the sampling module, is used to determine the placement position of the sampling module according to the distribution position of floating objects on the water surface, and correct the placement position according to the corresponding mapping rule between the number of mosquitoes captured at the placement position and the complexity of the floating object structure;

[0037] Determine the type of floating object distribution according to the distribution position of floating objects on the water surface around the placement position, and determine the sampling method according to the type of floating object distribution, including adjusting the direction change frequency of the carbon dioxide outlet, or adjusting the outlet direction of carbon dioxide, or adjusting the spraying pressure of carbon dioxide and the adsorption pressure of the negative pressure adsorption component;

[0038] Among them, the types of floating object distribution include dispersed surrounding type, dispersed non-surrounding type, and aggregation type; The operating state of the disturbance component is determined according to the complexity of the floating object.

[0039] Specifically, it further includes a power supply module, which is connected to the detection module, the sampling module, and the collaborative control module, and is used to provide the power required for the detection module, the sampling module, and the collaborative control module to work.

[0040] In implementation, the optional types of the power supply module are DC switching power supply, lithium polymer battery pack, redundant power supply, and the preferred implementation method is DC switching power supply. Those skilled in the art can make adaptive adjustments or replacements to the power supply type of the power supply module according to the actual application scenario or implementation environment.

[0041] Specifically, a high-speed centrifugal fan or a micro turbine fan is installed inside the negative pressure adsorption component to actively pump air, forming a local low-pressure area inside it, and mosquitoes are pressed into the inside of the negative pressure adsorption component by the atmospheric pressure.

[0042] In implementation, by setting up a detection module, a sampling module, and a cooperative control module, the sampling modules of the light wave trapping assembly, the carbon dioxide trapping assembly, the negative pressure adsorption assembly, and the disturbance assembly arranged on the water surface for changing the movement state of mosquitoes integrate multiple ways of attracting and capturing mosquitoes, and determine the placement position of the sampling body according to the type of floating object distribution, solving the problem that the existing mosquito capture technology has a low efficiency in capturing mosquitoes when dealing with different types of floating object distributions, and improving the efficiency of the sampling module in capturing mosquitoes.

[0043] Specifically, the cooperative control module is further configured to respectively obtain the number of mosquitoes captured at the placement position and the complexity of the floating object structure, perform a linear regression analysis on the number of mosquitoes captured at the placement position and the complexity of the floating object structure to generate a mapping function of the number of mosquitoes captured at the placement position and the complexity of the floating object structure, and calculate the corrected coordinate amount of the position according to the mapping function to correct the placement position of the sampling module.

[0044] Specifically, when generating the mapping function, the number of mosquitoes captured at the placement position and the complexity of the floating object structure are collected and calculated at the same moment. Those skilled in the art can understand that the processes of linear regression analysis and generating the mapping function are both well-known technical means in the art, so the specific processes of linear regression analysis and generating the mapping function will not be elaborated here.

[0045] Specifically, the complexity of the floating object structure is the sum of the product of the number of cracks on the floating object surface and the crack number weight coefficient and the product of the reciprocal of the crack area on the floating object surface and the crack area reciprocal weight coefficient; wherein, the sum of the crack number weight coefficient and the crack area reciprocal weight coefficient is 1.

[0046] In implementation, the placement position is corrected according to the corresponding mapping rule between the number of mosquitoes captured at the placement position and the complexity of the floating object structure, solving the problem of low efficiency in capturing mosquitoes at the placement position and improving the efficiency of capturing mosquitoes at the placement position.

[0047] Specifically, in the case where the area of a single floating object is small, the influence of the number of cracks on the complexity is greater than that of the crack area. Therefore, in the case where the area of a single floating object is small, the preferred embodiments of the crack number weight coefficient and the reciprocal of the crack area are 0.4 and 0.6 respectively. Those skilled in the art can also make adaptive adjustments to the crack number weight coefficient or the crack area reciprocal weight coefficient according to the actual area of the floating object and the actual situation.

[0048] Specifically, the collaborative control module is connected to the disturbance component, and is used to start the disturbance component under the condition that the complexity of the floating object structure is greater than the preset complexity; and is also used to determine whether to shut down the disturbance component under the condition that the complexity of the floating object structure is less than or equal to the preset complexity.

[0049] In practice, the preferred embodiment of the disturbance component is a bionic mechanical beating system, including a dual-degree-of-freedom crank slider mechanism, an eccentric wheel made of 304 stainless steel and a polyurethane beating plate, driven by a waterproof stepping motor, and generating an adjustable mechanical wave with an amplitude of 5-15mm and a frequency of 2-8Hz. Technicians in this field can make adaptive adjustments or replacements to the type of disturbance component according to the actual application scenario or implementation environment.

[0050] During implementation, the disturbance component can slap and vibrate the water surface, forcing the mosquitoes under the floating object to flee in fear, thus solving the problem that the mosquitoes under the floating object are difficult to be attracted by the light wave trapping component and the carbon dioxide trapping component. The determination of whether to activate the disturbance component is based on the complexity of the structure of the floating object closest to the sampling body, thus overcoming the problem that when the structure of the floating object is relatively simple, the activation of the disturbance component easily causes the mosquitoes to escape, thereby reducing the chance of collection. This ensures that mosquitoes in different positional relationships to the floating object can be attracted by the light wave trapping component and the carbon dioxide trapping component.

[0051] Specifically, the collaborative control module is connected to the image sensor to determine that the type of floating object distribution is agglomerated based on the ratio of the total area of ​​the figure formed by the edge lines of the floating object distribution on the surface of the small water body to the total area of ​​the water surface being less than a set ratio, and then determine the placement position of the sampling body to be the geometric center position of the figure; and determine that the type of floating object distribution is dispersed based on the ratio of the total area of ​​the figure formed by the edge lines of the floating object distribution on the surface of the small water body to the total area of ​​the water surface being greater than or equal to the set ratio.

[0052] Optionally, the ratio is set to have an optional range of [0.3, 0.5].

[0053] Preferably, the preferred embodiment of setting the ratio is 0.4.

[0054] Those skilled in the art can understand that the preferred embodiment of setting the ratio is a preferred embodiment under the condition that the small water body is a small ditch and the area is greater than 10 square meters. In practice, when the area of ​​the small water body is smaller, the ratio is usually set to be larger, which can better characterize the state of dispersion and aggregation. Those skilled in the art can adaptively adjust the set ratio according to the actual water body.

[0055] Specifically, the dispersed type includes a dispersed surrounding type and a dispersed non-surrounding type.

[0056] Specifically, the collaborative control module is connected to the carbon dioxide trapping component and the negative pressure adsorption component respectively, and is used to control the carbon dioxide trapping component to reduce the jet pressure and the negative pressure adsorption component to increase the adsorption pressure under the condition that the distribution type of the floating objects is the aggregation type and the placement of the sampling body is completed.

[0057] During implementation, under the condition that the distribution type of floating objects is the aggregation type and the sampling body is placed, the carbon dioxide trapping component is controlled to reduce the jet pressure and the negative pressure adsorption component is controlled to increase the adsorption pressure, thereby solving the problem that the excessive jet pressure causes the equipment to vibrate, which causes the negative pressure adsorption component to vibrate, resulting in the change of the negative pressure adsorption range of the negative pressure adsorption component and causing the mosquito group to flee in fear, and realizing that the carbon dioxide trapping component can still stably attract mosquitoes when a large number of mosquitoes gather; wherein, the negative pressure adsorption component increases the adsorption pressure, improves the adsorption capacity of mosquitoes, and improves the efficiency of catching mosquitoes when a large number of mosquitoes appear.

[0058] Specifically, the jet pressure is positively correlated with the ratio of the total area of ​​the figure formed by the edge connection lines of the floating objects on the surface of the small water body to the total area of ​​the water surface; the adsorption pressure is negatively correlated with the ratio.

[0059] In a possible embodiment, for every 0.01 less than the set ratio of the total area of ​​the figure formed by the edge connection lines of the floating objects on the surface of the small water body to the total area of ​​the water surface, the jet pressure is reduced by 0.01 kPa and the adsorption pressure is increased by 0.005 kPa.

[0060] Specifically, the collaborative control module is connected to the image sensor, and is also used to determine that the floating object distribution type is a dispersed surrounding type under the condition that the floating object distribution type is the dispersed type and the farthest straight-line distance from the floating object distribution point farthest from the shore of the small water body in the closed curve formed by connecting the edges of the floating object distribution on the surface of the small water body is less than or equal to a preset straight-line distance, then determine the placement position of the sampling body to be between the closed curve and the shore of the small water body, and control the carbon dioxide trapping component to adjust the exhaust direction of the carbon dioxide from within the closed curve to along the tangent direction of the closed curve.

[0061] Optionally, when the small water body is a ditch and has an area greater than 10 square meters, the optional range of the preset straight-line distance is [0.3m, 0.8m].

[0062] Preferably, the preset straight-line distance is 0.5 m.

[0063] During implementation, the exhaust direction of carbon dioxide is adjusted from within the closed curve to along the tangent direction of the closed curve by controlling the carbon dioxide trapping component according to the dispersed surrounding type of floating object distribution. Due to the distribution characteristics of the dispersed surrounding type, mosquitoes are more dispersed and do not gather at the center point. Therefore, changing the exhaust direction to along the tangent direction of the closed curve can make the exhaust follow the trajectory of the closed curve, thereby improving the collection efficiency and effectiveness of mosquitoes.

[0064] Specifically, the collaborative control module is connected to the image sensor, and is also used to determine that the floating object distribution type is a dispersed non-circular type under the condition that the floating object distribution type is the dispersed type and the farthest straight-line distance of the floating object distribution point farthest from the shore of the small water body in the closed curve formed by connecting the edges of the floating object distribution on the surface of the small water body is greater than a preset straight-line distance, then determine that the placement position of the sampling body is within the closed curve, and increase the direction change frequency of the carbon dioxide outlet.

[0065] Specifically, the direction change frequency of the carbon dioxide outlet is achieved by changing the direction of the outlet through a carbon dioxide capture assembly. Specifically, the direction change frequency of the carbon dioxide outlet can be achieved by a rotating shaft which is vertically arranged inside the carbon dioxide capture assembly and rotates around a vertical direction to drive the outlet to change direction, a rotating motor connected to the rotating shaft, a nozzle for exhausting gas, a gas delivery pipeline connected to the nozzle, and a storage tank for storing carbon dioxide gas.

[0066] Specifically, the frequency of direction change of the carbon dioxide outlet is positively correlated with the farthest straight-line distance from the floating object distribution point on the closed curve formed by the connecting line of the floating object distribution edge on the surface of the small water body to the shore of the small water body.

[0067] During implementation, for every 0.01m the farthest straight-line distance from the floating object distribution point on the closed curve formed by the connecting lines of the floating object distribution edges on the surface of the small water body exceeds the preset straight-line distance, the direction change frequency of the carbon dioxide outlet will be increased by 1 time / hour under the current direction change frequency; when the exceeding part is less than 0.01m, it will be counted as 0.01; when the exceeding part is not an integer multiple of 0.01, it will be calculated using the rounding rule.

[0068] In implementation, by determining that the distribution type of floating objects is a dispersed non-circular type, the placement position of the sampling body is determined to be within the closed curve, and the frequency of changing the direction of the carbon dioxide outlet is increased, thereby reducing the wider distribution of mosquitoes caused by the distribution type being a dispersed non-circular type. Therefore, by increasing the frequency of changing the outlet direction, the collection effectiveness of mosquitoes with irregular distribution and a wide range is improved.

[0069] Specifically, the cooperative control module intelligently regulates the carbon dioxide release amount of the carbon dioxide trapping component according to the ambient temperature. When the ambient temperature is lower than the set temperature, the natural diffusion range of carbon dioxide is insufficient, so the carbon dioxide release amount of the carbon dioxide trapping component is higher than the reference value, solving the problem that the trapping range of insects is affected due to the insufficient natural diffusion range of carbon dioxide. When the ambient temperature is greater than or equal to the set temperature, it is determined that the carbon dioxide trapping component releases carbon dioxide according to the reference value, and the natural diffusion of carbon dioxide is utilized to reduce the energy consumption of the carbon dioxide trapping component.

[0070] Optionally, the optional range of the set temperature is [22°C, 26°C].

[0071] Preferably, the preferred embodiment of the set temperature is 25°C.

[0072] Optionally, the optional range of the reference value of the carbon dioxide release amount is [1.2 L / min, 1.8 L / min].

[0073] Preferably, the preferred embodiment of the reference value of the carbon dioxide release amount is 1.5 L / min.

[0074] Those skilled in the art can understand that the preferred embodiments of the set temperature and the reference value of the carbon dioxide release amount are only the preferred implementation manners of the embodiments of the present invention under the environmental conditions where the small water body is a drainage ditch with an area greater than 10 square meters and the ambient temperature is relatively high between May and August. Those skilled in the art can make adaptive adjustments or replacements to the set temperature and the reference value of the carbon dioxide release amount under different application scenarios or specific conditions.

[0075] Specifically, when the ambient light intensity detected by the cooperative control module is greater than or equal to the set light intensity threshold, it is determined that the carbon dioxide release amount of the carbon dioxide trapping component 4 is higher than the reference value, preferably 180% of the reference value. When the ambient light intensity is less than the set light intensity threshold, the light wave trapping component and the carbon dioxide trapping component 4 are activated, and the carbon dioxide trapping component 4 releases carbon dioxide according to the reference value.

[0076] In practice, the set light intensity threshold is preferably 100 lux, and those skilled in the art can make adaptive adjustments or replacements to the set light intensity threshold according to the actual application scenario or implementation environment.

[0077] Specifically, the light wave trapping component can be an outdoor mosquito killing lamp or a CDC light trap, preferably a CDC light trap.

[0078] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
