[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Traps are mainly designed for the phototaxis and chemotaxis of insects. At the same time, the structure of the trapping device is modified according to the differences in the crawling or flying behaviors of different insects, and traps are added to make it easy for insects to enter and difficult to exit, so as to achieve the purpose of trapping and killing. The behavioral characteristics of different insects, especially the organs that receive external information substances, are different, and their lifestyles are also different. Therefore, designing an efficient trap often becomes more complicated. Domestic and foreign scholars have studied the control effects of different types of traps and found that the hanging height, layout density, shape and color of the traps, the color of the lure core, the wavelength of the light source, etc., all have an important influence on the trapping effect of pests, and even directly affect the ability to attract females and males. The number of lure cores can often directly affect the density of insect pheromones. However, the density of pheromones that insects are most sensitive to can often only be determined through repeated design of experiments, combining the two factors of the number of lure cores and the setting spacing, and drawing a better conclusion through comparative experiments.

[0036] The existing methods for determining the above-mentioned setting parameters often rely on setting multiple sets of parameters for repeated manual comparison experiments to determine the most suitable trap type, specifications, setting method and lure core. Moreover, the influence of meteorological factors in the air on insect trapping can only be vaguely judged by the change in the number of trapped insects, and the relationship between them cannot be accurately explained. In addition, in order to ensure the trapping effect, the flight behavior of insects when approaching the pheromone source has always been difficult to determine, and it is impossible to design the best trapping device in a targeted manner.

[0037] Figure 1 A schematic diagram of the structure of the analysis and evaluation system for the moth pest trapping device provided by the embodiment of the present invention, as shown in FIG. Figure 1As shown, the embodiment of the present invention provides an analysis and evaluation system for a moth pest trapping device, including a system outer wall 101, a laser radar detection device 102, and an environmental information collection device (by Figure 1 The device comprises one or more of a light detection module 1031, a temperature and humidity acquisition module 1032, and a wind speed and direction detection module 1033), a trap to be evaluated 104, and a signal processing device 105, wherein:

[0038] The system outer wall 101 is a rectangular parallelepiped structure, and an insect entrance is arranged on the surface of the system outer wall 101 .

[0039] In the embodiment of the present invention, the system outer wall 101 is a cubic frame structure with a length, width and height of 1 meter. A trap is set at the center of the system as a trapping device for moth pests. In addition, a circular area is set on the surface of the system outer wall 101 as an insect entrance, and the size of the circular area is the inscribed circle of the surface of the system outer wall 101.

[0040] The laser radar detection device 102 is arranged at the insect entrance, and is used to scan the moth pests passing through the insect entrance to obtain the flight information of the moth pests.

[0041] In the embodiment of the present invention, a cylindrical laser radar capable of 360-degree detection, namely, a laser radar detection device 102, is arranged at the center of the insect entrance, so that trapped insects can be detected at any time. The laser radar can determine the distance between the target pest and the laser radar at the current moment according to the signal returned by each laser pulse emission cycle; and can obtain the three-dimensional information of the target pest according to the signal returned by the laser beam blocked by the target pest at the same moment, and obtain the flight information of the moth pest through the subsequent data processing of the signal processing device 105.

[0042] The environmental information collection device is arranged on the surface of the outer wall of the system, and is used to collect real-time environmental information of the area where the analysis and evaluation system is located, so as to obtain the meteorological parameters of the area at the current moment.

[0043] In the embodiment of the present invention, one or more meteorological parameter collection modules are provided on the system outer wall 101 to collect real-time environmental information of the area where the analysis and evaluation system is located, and the collected meteorological parameters are sent to the signal processing device 105 .

[0044] The trap to be evaluated 104 is arranged inside the outer wall 101 of the system and is used to trap moth pests;

[0045] The signal processing device 105 is used to process the insect flight information and the meteorological parameters according to a preset evaluation mode and based on the type of the trap 104 to be evaluated, so as to obtain an evaluation result of the trap 104 to be evaluated.

[0046] In the embodiment of the present invention, the signal processing device 105 obtains the three-dimensional information of the target pest through the laser radar, and can classify insects with similar data according to the length, width and height of the target pest to determine whether they are the target pests trapped by the trap; at the same time, the pest flight distance h and the crossing time t can be calculated according to the flying direction of the pest in the laser detection area. Calculate the flight speed v of the pest. In addition, the flight path of the pest can be drawn according to the position information of the pest at each moment. Further, the signal processing device 105 can be based on the time when the moth pest is detected, and extract the meteorological parameters at that moment from the environmental information collection device, and perform a comprehensive analysis with the three-dimensional information of the target pest and the insect body flight information, and send and store the corresponding data and analysis results to the data server for researchers to refer to, so as to obtain the evaluation results of the trap.

[0047] The analysis and evaluation system for the moth pest trapping device provided by the embodiment of the present invention records the flight behavior and meteorological factors of the moth pests during trapping, and analyzes the effects of temperature, humidity, light intensity, irradiation direction, wind force, and wind direction in the air on the trapping of moth pests, thereby being able to identify whether the trap can successfully capture the lured pests and accurately evaluate the trapping effects of different types of traps and pheromones on moth pests.

[0048] On the basis of the above embodiment, the signal processing device further includes a mode selection unit, a first processing unit and a second processing unit, wherein:

[0049] The mode selection unit is disposed on the outer surface of the outer wall of the system and is used to adjust the preset evaluation mode of the analysis and evaluation system according to the type of the trap to be evaluated;

[0050] The first processing unit is used to obtain the body size, flight path and flight speed of the moth pest according to the insect flight information;

[0051] The second processing unit is used to process the insect size, the flight path and the flight speed in combination with the meteorological parameters according to the preset evaluation mode, so as to obtain an evaluation result of the trap to be evaluated according to the processing result.

[0052] Among them, the preset evaluation modes include: pheromone evaluation mode, trap effectiveness evaluation mode, light lure evaluation mode and color lure evaluation mode.

[0053] In the embodiment of the present invention, for different types of traps to be evaluated, the mode selection unit is adjusted to the corresponding evaluation mode. If the preset evaluation mode is the pheromone evaluation mode, it can be used to test the pheromone used in the trap core for the trapping effect on moth pests. By detecting the lighting conditions, wind speed and direction conditions, and temperature and humidity conditions when trapping moth pests, and combining the flight behavior of insects, the luring effect of the trap core on the target pests in the natural environment is detected, and whether it can continue to effectively attract the target pests is observed, and its luring effect is evaluated.

[0054] Specifically, the light sensor can be used to detect the light conditions when trapping moth pests. When the system detects insects, the light intensity I in the direction of the insect's flight is collected under the current situation; the wind speed and direction meter collects the wind speed v at the time of insect invasion, and takes the north as the basic direction, records the angle θ1 between the wind direction and the north, and obtains the angle θ2 between the wind direction and the insect's flight direction according to the flight direction θ3 of the invading insect; the temperature and humidity sensor records the temperature T and relative humidity RH at the current moment. The signal processing device summarizes the above-collected data information and sends it to the data server together with the insect flight behavior records collected by the laser radar detection device. Furthermore, according to the wind speed v and the angle θ1 of the wind direction, the intensity of light I, the temperature T and the relative humidity RH, the diffusion direction of pheromones, the coverage range s and the change of pheromone concentration ρ on the lure core can be calculated, wherein the diffusion direction is only affected by the wind direction θ1, which is 180° with the wind direction, and the coverage range s is affected by the wind speed v and the pheromone concentration ρ on the lure core. Since the pheromone concentration used when the lure is initially installed is a known quantity, and its volatilization rate will change with the light intensity I, temperature T, relative humidity RH and time t, and the influence of different meteorological conditions on the volatilization rate of the lure can be determined through long-term observation and quantitative experiments, the relationship curve between the pheromone concentration ρ on the lure and the meteorological factors can be finally obtained ρ = f (I, T, RH), from which the coverage range of the lure s = f (ρ, v, t) can be derived. At the same time, the wind direction is combined to determine the effective luring direction of the lure, and compared with the direction of the pests entering the system, and the functional relationship between the insect invasion direction and the trapping range of the lure is further established, and the evaluation index is set to achieve the evaluation of the trapping effect of the lure.

[0055] If the preset evaluation mode is the trap effectiveness evaluation mode of the trapping device, it can be used to evaluate the efficiency of the trapping device in trapping moth pests. The number of insects flying into the system and the number of insects flying out detected by the laser radar are compared with the statistical data of the detection device inside the trap, so as to determine the success rate of the trapping of pests. Specifically, the laser radar can detect the flight path of the insects, determine whether the insects fly into the system or fly out of the system, and record the number of insects entering the system Y2 and the number of insects flying out of the system Y3, and send the data to the data server. The counting module inside the trap records the number of insects entering the trap Y1, and sends the counting information to the data server. The data server can establish a functional relationship between the above data and calculate the successful trapping rate of the trap η1 = (Y2-Y3) / Y1, so as to evaluate the trapping effect of the trap. In addition, the analysis and evaluation system can detect the changes in the number of traps and the success rate of trapping under different lighting conditions, temperature and humidity conditions, and wind speed and wind direction. The corresponding moth pest trapping quantity variation curve y=f(η, I, T, RH, θ1, V) is drawn to establish a corresponding database. According to the number of trapped insects under different climatic environments, the degree to which each trap is affected by various climatic conditions is judged, thereby realizing the evaluation of the trapping effect of the trap.

[0056] If the preset evaluation mode is the light-attracting evaluation mode, the light-attracting effect of the insect-attracting lamp can be evaluated. By collecting the light intensity, air temperature and humidity conditions when trapping moth pests, and combining the flight behavior of insects, the effect of the trap can be evaluated. Specifically, the light sensor installed on the outside of each plane of the system can be used to detect the light conditions when trapping moth pests. When the system detects insects, the light intensity I in the direction of the insect's flight in the current situation is collected, and combined with the invasion direction of the moth pests detected by the laser radar detection device, the relationship between the light intensity and the insect's flight direction η2=f(θ3, I) is judged. In an embodiment of the present invention, the light sensor can detect the light intensity and wavelength of the light emitted by the insect-attracting lamp outside the system, so as to detect whether the trap can emit a stable light source for a long time, whether the wavelength and intensity of the light source will change or decay with time, and thus determine the effective working time of the insect-attracting lamp. And according to the number of insects flying in and out of the system and the number of insects recorded by the insect-attracting lamp, the trapping success rate η of the insect-attracting lamp can be calculated, and the working efficiency of different insect-attracting lamps can be evaluated. It should be noted that as the temperature and humidity in the air change, the effect of atmospheric molecules refraction on the light source of the insect trap lamp may be different, which may lead to different larval effects of the insect trap lamp under different conditions. The analysis and evaluation system can detect the number of insects attracted by the insect trap lamp under different temperature and humidity conditions, and judge whether the different environmental temperature and humidity conditions will affect the insect trap lamp's insect trap effect and the extent of the impact based on the difference in the number, and detect the stability of the trap under various environmental conditions, so as to evaluate the trap's trapping effect.

[0057] If the preset evaluation mode is the color lure evaluation mode, the trapping effect of the color lure board can be evaluated. The analysis and evaluation system can evaluate the effect of the trap by collecting the air temperature and humidity conditions when trapping moth pests, as well as the invasion direction of the pests. Specifically, the color lure board is fixed at the center of the system, and its facing direction and height will not change during the larval process. The laser radar in the system can detect the invasion direction of moth pests. By measuring the flight path of the pests, it can be determined whether it flies in from the front of the insect trap board and whether it is successfully stuck to the trap board. According to the total number of pests flying in and out of the system Y2 and Y3, and the number of insects on the insect trap board Y1 afterwards, the trapping efficiency η1 of the insect trap board is calculated, thereby realizing the evaluation of the trapping efficiency of the insect trap board. And according to whether the pests entering the system from different directions have flying behavior, it can be judged what changes will occur in the trapping efficiency of the insect trap board when the pests approach the insect trap board from different directions. Furthermore, since the stickiness of the insect trap will continue to decrease over time, and the stickiness duration of the insect trap varies with the air temperature and humidity. Therefore, the analysis and evaluation system can detect the number of insects n1 of the installed insect trap after being air-dried for different times t under natural conditions without insects, and the number of insects n2 of the new insect trap installed at the same time, and obtain the insect trapping efficiency η3=n1 / n2 of the insect trap at different times, calculate the stickiness decay curve y3=f(η3, t) of the insect trap, and thus determine the effective working time of the insect trap. In addition, by detecting the insect trapping efficiency of the insect trap after being air-dried under different air temperature and humidity conditions, the influence of temperature T and humidity RH on the stickiness decay curve y3 can be calculated, and the influence of air temperature and humidity on the working efficiency of the color trap can be detected, so as to achieve the purpose of evaluating the insect trapping effect of the insect trap. On the basis of the above embodiment, an insect entrance is arranged on the surface of the outer wall of the system, the size of each insect entrance is the inscribed circle of the surface, and a laser radar detection device is arranged at the center of each inscribed circle, and each laser radar detection device emits laser pulses parallel to the plane of the corresponding insect entrance.

[0058] In the embodiment of the present invention, reference may be made to Figure 1 As shown, in the planes of the six system outer walls of the cube-structured analysis and evaluation system, each face has an insect entrance, and a 360-degree scanning laser radar is installed at the center of the circle, which can accurately measure the approach direction of moth pests. By using the laser radar to monitor the six directions of the trap, it is known from which direction the trapped moth pests approach the trap without the interference of human factors. In an embodiment of the present invention, the laser radar and the system outer wall constitute a moth pest flight detection subsystem, wherein the laser radar can achieve 360-degree scanning in the direction of the detection plane, Figure 2 The schematic diagram of laser radar scanning at the insect entrance provided by the embodiment of the present invention can be referred to Figure 2As shown, when no insects enter, the lidar can scan the analysis and evaluation system to construct a three-dimensional model.

[0059] Furthermore, the laser radar detection device can detect the direction of the moth pests entering the trap, and determine the pest invasion direction according to the position of the laser radar that detects the pests. In the embodiment of the present invention, according to the situation that the pests block the laser beam emitted by the laser radar, the volume V of the pests entering the analysis and evaluation system and their specific position can be calculated, and the flight path and flight speed of the pests can be calculated according to the change of their position.

[0060] Specifically, when the trapped moth pest enters, the insect body blocks the laser beam, causing the echo signal received by the radar to change. Figure 3 A schematic diagram of a laser radar scanning an insect body provided by an embodiment of the present invention, such as Figure 3 As shown, the distance l between the moth pest and the laser radar is calculated based on the time difference between the laser emission pulse and the echo signal pulse and the speed of light, and the insect's position x = f(l, θ) is calculated based on the angle θ of the laser beam. Since the size of moth pests is different, the number of laser beams blocked by the insect body is also different. The height h of the insect body at that moment can be calculated based on the number of laser beams blocked by the insect on the vertical plane, and the change of the insect body height h during the horizontal scanning of the radar can be recorded to obtain the side observation data of the pest, and then generate the side image of the pest, so that researchers can classify and identify the insect through the image, and determine whether the trap has attracted insects that are not targeted by the core.

[0061] In addition, the signal processing device can calculate the flight speed of each segment of the pest and draw the flight path of the insect based on the scanning cycle of the laser radar and the different positions of a single pest each time it is detected; and based on the flight distance of each small segment, calculate the pest's crossing time, path and speed within the entire laser radar detection range.

[0062] On the basis of the above-mentioned embodiment, the environmental information collection device comprises: a light detection module, which is arranged on the outer surface of the outer wall of the system and is used to detect light data when moth pests invade.

[0063] On the basis of the above embodiment, the environmental information collection device further includes: a temperature and humidity collection module, which is arranged on the top of the analysis and evaluation system and is used to detect air temperature and humidity data when moth pests invade.

[0064] On the basis of the above embodiment, the environmental information collection device further includes: a wind speed and direction detection module, which is arranged on the top of the analysis and evaluation system and is used to detect air wind speed and wind direction data when moth pests invade.

[0065] Preferably, reference can be made to Figure 1 As shown, in the embodiment of the present invention, the environmental information collection device is composed of a light detection module, a temperature and humidity collection module, and a wind speed and direction detection module, wherein a light detection module is provided on the outer wall of each system equipped with a laser radar, so as to record the light intensity received by insects invading from different directions. The temperature and humidity collection module and the wind speed and direction detection module are installed on the top of the analysis and evaluation system, so that they can accurately collect environmental information data.

[0066] Specifically, when detecting moth pests, the environmental information collection device will simultaneously record the meteorological parameters at that moment, among which the light detection module can record the light intensity received by the system in all directions at the current moment, thereby recording the changes in the light intensity and incident light angle of sunlight or light at the system's location during the day, and counting the light data when the system detects the invasion of moth pests, thereby judging the effect of the trap on the trapping of moth pests at different time periods within a day, and judging the extent of the influence of different light conditions on the trapping of moth pests based on whether there is light in the morning, noon, afternoon, evening and night, and the time when the pests are captured.

[0067] The anemometer will record the wind speed and direction information at the current location of the system, thereby recording the temperature and humidity changes at the location of the system during the day, and collecting statistics on the air temperature and humidity data when the system detects the invasion of moth pests. Based on the differences in the amplitude and range of temperature changes in a day under different seasonal conditions, or the differences in the flight behavior of moth pests under long-term dry or humid conditions, the effects of different temperature and humidity ranges on the flight behavior of moth pests can be determined, and the effectiveness of the trap can be evaluated.

[0068] The air temperature and humidity detection device will record the air temperature and humidity information of the environment where the system is located, and can record the changes in wind speed and wind direction at the location of the system during the day, and count the air wind speed and wind direction data when the system detects the invasion of moth pests. In this way, the influence of wind speed and wind direction in the air on the flight behavior of insects can be judged, and the diffusion range and concentration of the lure core can be calculated according to the diffusion speed and direction of the lure core of the trap, the direction of the pest's flight can be detected, the influence of the concentration change of the lure core on the effect of the trap can be studied, and its effect can be evaluated.

[0069] Furthermore, each environmental information collection device will send the collected meteorological parameters to the signal processing device. The signal processing device can calculate the direction of the ambient incident light according to the difference in light intensity in different directions, and package it with other information and send it to the data server.

[0070] Figure 4 A schematic diagram of a flow chart of an analysis and evaluation method for a moth pest trapping device provided by an embodiment of the present invention, such as Figure 4 As shown, an embodiment of the present invention provides an analysis and evaluation method for an analysis and evaluation system for a moth pest trapping device based on the above embodiments, including:

[0071] Step 401, obtaining the flight information of the moth pests when they invade through the laser radar detection device of the analysis and evaluation system;

[0072] Step 402, obtaining meteorological parameters when moth pests invade through the environmental information collection device of the analysis and evaluation system;

[0073] Step 403: Analyze and evaluate the trapping effect of the trap to be evaluated based on the insect flight information and the meteorological parameters.

[0074] In the embodiment of the present invention, the types of traps and lures in the analysis and evaluation system are not specifically limited. Therefore, different traps and lures can be installed inside the analysis and evaluation system in the above embodiment, and the flight behavior of moth pests can be used to determine the attracting effect of different traps and pheromones on pests, as well as whether different pheromones will interfere with each other. Specifically, the embodiment of the present invention uses the ALP-01 Lighting Passport Pro light sensor as a light detection module, the SEN-R TR-1 air temperature and humidity sensor as a temperature and humidity acquisition module, the NHFSX48 wind speed and direction sensor as a wind speed and direction detection module, and the RPLIDAR A3 laser radar as a laser radar detection device. Among them, the light sensor can be attached to the corners of the six surfaces of the outer wall of the system to detect the light intensity in different directions; the laser radar is installed at the center of the six insect entrances on the outer wall of the system, and continuously scans the surroundings 360°.

[0075] Furthermore, a fall armyworm trap with sex attractant as the lure core is placed in the center of the system, and the air flow direction and speed are detected by an anemometer to estimate the diffusion direction and range of the pheromone. Based on the direction of fall armyworm entry detected by the laser radar, it is determined whether it enters the trap from the direction of pheromone diffusion, and the lure core's effect on fall armyworm is determined. The atmospheric temperature and humidity are detected by the temperature and humidity sensor to estimate the effective action time of the lure core, and the effect of the lure core is evaluated based on the trend of the number of fall armyworms captured. The flight behavior of insects in the laser radar detection device can be used to determine whether the insects fly out of the system again after being lured into the system, thereby generating an error count, and then the trapping effect of the trap can be evaluated.

[0076] Furthermore, the frequency-vibration insecticidal lamp was analyzed and evaluated and placed in the analysis and evaluation system. The insecticidal lamp uses a high-power larval light source from Shellyte, which continuously emits purple light to attract pests. The system uses a peripheral light sensor to detect the light intensity released in all directions outside the system to determine the effective insect-attracting range of the insecticidal lamp, and based on the changes in the ambient light and the changes in the number of insects attracted by the insect-attracting lamp, it determines the impact of the natural lighting environment on the insect-attracting effect of the insect-attracting lamp. In addition, as time changes, the light sensor can detect whether the light intensity released by the insect-attracting lamp will be blocked by insect corpses or attenuated with changes in power, thereby evaluating the efficiency and sustainability of the insect-attracting lamp.

[0077] Furthermore, a 20×25cm yellow insect trap is used for trapping and placed in the center of the analysis and evaluation system. The laser radar can detect insects trapped from all directions, and the optimal installation position of the insect trap is determined based on the fixed position and orientation of the insect trap and the direction of the insect's entry into the insect trap. At the same time, based on the flight behavior of insects in the system detected by the laser radar and the number of insects detected, it can be calculated whether the trapped insects successfully hit the insect trap and were stuck, thereby evaluating the trapping effect of the insect trap.

[0078] Furthermore, in different analysis and rating systems in a field, brand new insect traps and insect traps of the same type that have been air-dried for 12 hours, 24 hours, 36 hours, and 48 hours in an insect-free natural environment can be installed at the same time, and they can be placed in the field for trapping detection at the same time. According to the different numbers of insects trapped by different insect traps and the different trapping success rates η1 detected by each system, the viscosity decay law of the insect trap can be determined, and the viscosity decay law of the insect trap can be determined according to different air temperatures. In addition, by reducing the air-dried time interval of the insect trap, a more detailed viscosity decay curve can be drawn, and the efficiency of the insect trap can be evaluated more accurately.

[0079] The analysis and evaluation method for a moth pest trapping device provided in an embodiment of the present invention records the flight behavior and meteorological factors of moth pests during trapping, and analyzes the effects of air temperature, humidity, light intensity, irradiation direction, wind force, and wind direction on moth pest trapping, thereby being able to identify whether the trap can successfully capture the lured pests and accurately evaluate the trapping effects of different types of traps and pheromones on moth pests.
