Description

Technical Field

[0001] The present invention belongs to the technical field of crop pest control, and in particular relates to a method and system for integrated detection and killing of crop pests. Background Art

[0002] In the field of crop pest control, common methods include chemical control and physical control.

[0003] Chemical treatment generally uses various pesticide spraying, but excessive pesticide spraying not only harms the environment, but also leaves a large amount of pesticide residue on the crops, thus affecting the quality of the crops themselves.

[0004] Physical control methods commonly include insect attracting lamps and insect attracting boards. Insect attracting boards have a limited range of attracting pests. For large-scale crop planting, a large number of insect attracting boards are required, which consumes a lot of manpower and material resources. Traditional insect attracting lamps usually use a broad spectrum method to attract insects, and then use negative pressure to suck them into the air duct. This type of insect attracting lamp has the following shortcomings in practical applications: (1) Different types of insects are related to the spectrum of the attractant, as well as the insect's own nervous system and compound eye structure. Using a unified spectrum method cannot accurately attract and kill different crop pests, and will also result in indiscriminate killing of beneficial insects and pests; (2) Generally speaking, the greater the intensity of light, the more it can attract pests from far away. However, when the intensity of light reaches a certain level, the pests will only fly around near the insect attracting lamp due to their photophobia and will not be lured to a distance close enough to be killed. This results in the insect attracting lamp only attracting pests but failing to eliminate them. Summary of the invention

[0005] The purpose of the present invention is to address the problems existing in the prior art and provide a method and system for detecting and killing crop pests. The method and system can attract as many pests as possible by selecting light sources with the wavelengths that can attract the pests the most, and can better capture the attracted pests by changing the brightness of the light sources, thereby greatly improving the pest control effect.

[0006] To achieve the above object, on the one hand, the present invention provides a method for detecting and killing crop pests, comprising the following steps: Turn on light sources with different wavelengths and control the light sources to operate at maximum brightness to attract pests; Control the light source to run in intervals from low to high wavelengths, monitor the number and type of pests attracted by the light source, determine the wavelength that attracts the most pests through a scanning algorithm, and lock the wavelength to allow the light source to continue running at the locked wavelength; Monitor the number of pests in real time. When the number of pests reaches a predetermined number, control the light source to gradually reduce its brightness. When the brightness of the light source reaches the target brightness, turn on the insect-catching mechanism to capture pests. When the number of pests is lower than the lower limit, turn off the insect-catching mechanism and control the light source to restore to the brightest state according to the locked wavelength.

[0007] By using light sources of different wavelengths to attract pests and dynamically adjusting the operating status of the light source according to the number and type of pests attracted, the attracted pests can be better captured, thereby greatly improving the pest control effect. It can also improve the protection efficiency of crops, reduce the use of chemical pesticides, and thus reduce environmental pollution.

[0008] Furthermore, the rotation interval of different wavelengths in the light source is not less than 30 minutes. Setting the rotation interval of different wavelengths in the light source to be not less than 30 minutes can avoid the adaptability of pests to specific wavelengths and improve the detection and killing effect.

[0009] Furthermore, the scanning algorithm includes controlling the light source to start from the shortest wavelength, and at predetermined intervals, rotating the light sources of different wavelengths upward at the target interval wavelength, monitoring the number of pests under each wavelength state of the light source, and determining the wavelength of the light source with the largest number of pests after comparison. In this way, the wavelength that attracts the most pests can be found more accurately, thereby improving the detection and killing efficiency.

[0010] Furthermore, a capture algorithm is used to determine when the number of pests reaches a predetermined number. The capture algorithm includes real-time monitoring of the number of pests at the capture port when the light source brightness is at its lowest. When the number of pests reaches a predetermined number, the negative pressure air duct is controlled to open. When the number of pests is lower than a lower limit, the negative pressure air duct is closed. This ensures that the pests are effectively captured while avoiding excessive energy consumption.

[0011] On the other hand, the present invention provides an integrated detection and killing system for crop pests, comprising: a lighting module, a scanning and monitoring module, a capturing module and a control module; The light module is used to release light sources of different wavelengths to attract pests; The scanning monitoring module is used to scan the number of pests attracted by the light source at various wavelengths and continuously monitor the number of pests near the light module; The capture module is used to capture pests; The control module is used to control the light module to alternately emit light of different wavelengths, control the scanning and monitoring module to scan under various wavelength states, determine the wavelength that attracts the most pests based on the scanning results, and then control the light module to lock the wavelength, and then control the scanning and monitoring module to continuously monitor the number of pests near the light module, and when the number of pests detected reaches an upper limit, control the light module to adjust the light brightness under a fixed wavelength state, and control the capture module to capture pests.

[0012] Through the combination of lighting module, scanning monitoring module, capture module and control module, integrated detection and killing of crop pests can be achieved, improving processing efficiency and accuracy.

[0013] Furthermore, the lighting module includes an inverted pyramid-shaped lampshade and a plurality of LED lamp beads with different wavelengths arranged on the pyramid lampshade. The wavelength range of the LED lamp beads is between 300-800 nanometers, including but not limited to ultraviolet light, blue light, and green light.

[0014] Through the design of an inverted pyramid-shaped lampshade and multiple LED lamp beads with different bands arranged on the pyramid lampshade, different types of pests can be effectively attracted and the detection and killing range is improved.

[0015] Furthermore, the scanning monitoring module includes a light scattering receiver for real-time monitoring of the attracted pests and transmitting the results to the control module.

[0016] Furthermore, the capture module includes a negative pressure device and a storage bin, which are used to form an air duct near the light module when the negative pressure device is activated to capture pests attracted by the light module.

[0017] By forming an air duct near the light module through the negative pressure device, pests attracted by the light module can be effectively captured, thereby improving the capture efficiency.

[0018] Furthermore, the control module includes: The light control unit is used to control the light module to release lights of different wavelengths in rotation and control the brightness change of the light module; The feedback unit is used to compare the results transmitted by the scanning monitoring module to determine the wavelength that attracts the most pests, so that the light control unit can determine the wavelength. After the light control unit determines the wavelength, it continuously feeds back the number of pests detected by the scanning monitoring module; The air duct switch control unit is used to control the negative pressure device to start after the feedback unit receives the information from the scanning monitoring module that the number of pests has reached an upper limit, generate air ducts near the input end of the negative pressure device to attract and capture pests, and control the negative pressure device to close after the feedback unit receives the information from the scanning monitoring module that the number of pests is lower than a lower limit.

[0019] By controlling the working band and brightness of the light source through the light control unit, the working state of the light module can be dynamically adjusted according to actual needs, which improves the flexibility and adaptability of the system. Through the cooperation of the feedback unit, the wavelength and brightness of the light module can be dynamically adjusted according to the monitoring results, further improving the detection and killing efficiency; after the feedback unit determines the wavelength that attracts the most pests, the air duct switch control unit cooperates with the feedback unit to continuously feedback the number of pests near the light module, and uses the air duct switch control unit to open and close the negative pressure device to attract and capture pests, which can ensure that the pests are effectively captured while avoiding excessive energy consumption.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. By using light sources of different wavelengths to attract pests, and dynamically adjusting the brightness of the light source according to the number and type of attracted pests, the attracted pests can be better captured, thereby greatly improving the pest control effect, and can also improve the protection efficiency of crops, reduce the use of chemical pesticides, and thus reduce environmental pollution; 2. By changing the brightness of the light source, the light avoidance of pests can be effectively overcome, allowing nearby pests to be closer to the capture port, thereby improving the capture effect; 3. Setting the rotation interval of different wavelengths in the light source to be no less than 30 minutes can avoid the adaptability of pests to specific wavelengths and improve the detection and killing effect; 4. When the number of pests reaches a predetermined number, the negative pressure air duct is controlled to open, and when the number of pests is lower than the lower limit, the negative pressure air duct is closed, which can ensure that the pests are effectively captured while avoiding excessive energy consumption.

[0023] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only 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.

[0024] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] like Figure 1 As shown in FIG. 4 , this embodiment provides a method for detecting and killing crop pests, including the following steps: Turn on light sources with different wavelengths and control the light sources to operate at maximum brightness to attract pests; Control the light source to run in intervals from low to high wavelengths, monitor the number and type of pests attracted by the light source, determine the wavelength that attracts the most pests through a scanning algorithm, and lock the wavelength to allow the light source to continue running at the locked wavelength; Monitor the number of pests in real time. When the number of pests reaches a predetermined number, control the light source to gradually reduce its brightness. When the brightness of the light source reaches the target brightness, turn on the insect-catching mechanism to capture pests. When the number of pests is lower than the lower limit, turn off the insect-catching mechanism and control the light source to restore to the brightest state according to the locked wavelength.

[0026] By using light sources of different wavelengths to attract pests and dynamically adjusting the operating status of the light source according to the number and type of pests attracted, the attracted pests can be better captured, thereby greatly improving the pest control effect. It can also improve the protection efficiency of crops, reduce the use of chemical pesticides, and thus reduce environmental pollution.

[0027] In this embodiment, before running this method, it is necessary to exclude wavelengths that can attract beneficial insects, so as to avoid capturing and killing beneficial insects when capturing harmful insects.

[0028] Specific: Common beneficial insects include dragonflies, bees, ladybugs, and mantises. Dragonflies are carnivorous insects that prey on pests such as flies and mosquitoes; bees are important pollinators that provide necessary pollination services for many plants and promote the growth and reproduction of crops; both adults and larvae of ladybugs are predatory insects, and their main food is aphids, which helps control the number of aphids and protect crops; mantises are carnivorous insects that can prey on a variety of pests, such as locusts and moth larvae, which are beneficial to agriculture and have a protective effect on crops.

[0029] Among these beneficial insects, dragonflies: Dragonflies are visual predators that are particularly sensitive to ultraviolet (UV) and blue light in the spectrum. Studies have shown that dragonflies can see ultraviolet wavelengths between 300-400 nanometers and blue light wavelengths between 400-500 nanometers. These wavelengths of light are very conspicuous to dragonflies and can help them accurately capture prey in flight.

[0030] Bees: Bees are also very sensitive to ultraviolet (UV) light, especially wavelengths around 365 nanometers. In addition, they can see blue and violet light waves, which help them identify flowers and collect nectar. In beekeeping practice, using specific wavelengths of light can guide bees to specific flowers and improve pollination efficiency.

[0031] Ladybugs: Ladybugs are particularly sensitive to red light in the spectrum, especially red light with wavelengths between 620-750 nanometers. This sensitivity may be related to their behavior in finding food, because many plants release compounds containing red pigments when damaged by insects to attract natural enemies such as ladybugs to prey on pests.

[0032] Praying mantis: Praying mantis eyes can sense a wide range of the light spectrum, from ultraviolet to near infrared, but they are most sensitive to green light waves, around 530 nanometers. This sensitivity allows praying mantises to better camouflage themselves against green leafy backgrounds, and also helps them locate prey more accurately when hunting.

[0033] Therefore, in the set light source, the light of these wavelengths needs to be removed in advance.

[0034] In this embodiment, the rotation interval of different wavelengths in the light source is not less than 30 minutes. Setting the rotation interval of different wavelengths in the light source to be not less than 30 minutes can avoid the adaptability of pests to specific wavelengths and improve the detection and killing effect.

[0035] In this embodiment, the scanning algorithm includes controlling the light source to start from the shortest wavelength, and at predetermined intervals, rotating the light sources of different wavelengths upward at the target interval wavelength, monitoring the number of pests at each wavelength of the light source, and determining the wavelength of the light source with the largest number of pests after comparison. This can more accurately find the wavelength that attracts the most pests and improve the detection and killing efficiency.

[0036] Specifically, during the spectrum cycle, starting from 300 nanometers, every 30 minutes, different bands of LED light sources are turned on continuously at intervals of 50 or 100 nm.

[0037] A capture algorithm is used to determine when the number of pests has reached a predetermined number. The capture algorithm includes real-time monitoring of the number of pests at the capture port when the light source is at its lowest brightness. When the number of pests reaches a predetermined number, the negative pressure air duct is controlled to open. When the number of pests is lower than the lower limit, the negative pressure air duct is closed. This ensures that the pests are effectively captured while avoiding excessive energy consumption.

[0038] In actual operation, after determining the wavelength band of the spectrum, the brightness of the light source is controlled so that it gradually dims from the strongest. According to the phototaxis of pests, the brighter the light source, the more it attracts insects farther away, and the darker the light source, the more it attracts nearby insects to a position close to the capture port, making it easier to capture.

[0039] In this embodiment, a plurality of photodiodes are installed at the backlight of the light source, facing away from the light source for detection. Under normal conditions, the reflected wavelength / reflected light intensity is fixed. When an insect flies over, the light finds the insect, causing light refraction, and then generating noise. For large insects, high-intensity noise is formed, and for small insects, a low-intensity noise curve is formed. This can reflect the number of approaching insects, and can distinguish the number of large and small insects, and can determine when to reduce the light intensity. Moreover, when the high-energy pulses and low-energy pulses obtained by the photodiode reach a certain density, the brightness of the light is gradually reduced to allow the flying insects to move closer to the capture port, and then the capture device is started, the air duct is opened, and the negative pressure sucks the flying insects away.

[0040] In addition, in order to enhance the effect of luring pests, a female pest sex attractant chamber is set at the capture port, which is filled with female attractants to attract male pests.

[0041] On the other hand, according to the same technical concept of the above embodiment, a detection and killing system for crop pests is also provided, comprising: a lighting module 1, a scanning and monitoring module 2, a capture module 3 and a control module 4; The light module 1 is used to release light sources of different wavelengths to attract pests; The scanning monitoring module 2 is used to scan the number of pests attracted by the light source at various wavelengths, and continuously monitor the number of pests near the light module 1; The capture module 3 is used to capture pests; The control module 4 is used to control the light module 1 to alternately emit light of different wavelengths, control the scanning monitoring module 2 to scan under various wavelength states, determine the wavelength that attracts the most pests based on the scanning results, and then control the light module 1 to lock the wavelength, and then control the scanning monitoring module 2 to continuously monitor the number of pests near the light module 1, and when the number of pests detected reaches an upper limit, control the light module 1 to adjust the light brightness under a fixed wavelength state, and control the capture module 3 to capture pests.

[0042] Through the combination of the lighting module 1, the scanning monitoring module 2, the capturing module 3 and the control module 4, integrated detection and killing of crop pests can be achieved, thereby improving the processing efficiency and accuracy.

[0043] The light module 1 includes an inverted pyramid-shaped lampshade 11 and a plurality of LED lamp beads 12 with different wavelengths arranged on the pyramid lampshade 11. The wavelength range of the LED lamp beads 12 is between 300-800 nanometers, including but not limited to ultraviolet light, blue light, and green light. By comprehensively using a variety of colored lights, various pests can be attracted, thereby increasing the efficiency of capturing pests.

[0044] Compared with rod-shaped and elliptical lights, this shape of light has a better phototaxis effect on insects. Moreover, the inverted pyramid has a large area, on which a large number of different LED light sources can be implanted, with a wavelength of 300-800 nanometers. After phototaxis tests on more than 300 species of insects, they are all distributed in a very narrow band. The light energy is normally distributed, not a step. By controlling which of all LED lights are turned on and which are not, lights with different radiation wavelengths can be obtained.

[0045] Through the design of the inverted pyramid-shaped lampshade 11 and a plurality of LED lamp beads 12 with different wavelengths arranged on the pyramid lampshade 11, different types of pests can be effectively attracted and the detection and killing range is improved.

[0046] The scanning monitoring module 2 includes a light scattering receiver for real-time monitoring of the attracted pests and transmitting the results to the control module 4 .

[0047] The capture module 3 includes a negative pressure device 31 and a storage bin 32 , which is used to form an air duct near the light module 1 to capture the pests attracted by the light module 1 when the negative pressure device 31 is activated.

[0048] By forming an air duct near the light module 1 through the negative pressure device 31, the pests attracted by the light module 1 can be effectively captured, thereby improving the capture efficiency.

[0049] The control module 4 includes: The light control unit is used to control the light module 1 to release lights of different wavelengths in rotation and control the brightness change of the light of the light module 1; The feedback unit is used to compare the results transmitted by the scanning monitoring module 2 to determine the wavelength that attracts the most pests, so that the light control unit can determine the wavelength, and after the light control unit determines the wavelength, it continuously feeds back the number of pests monitored by the scanning monitoring module 2; The air duct switch control unit is used to control the negative pressure device 31 to start after the feedback unit receives the information that the number of pests detected by the scanning monitoring module 2 has reached an upper limit, generate air duct suction and capture pests near the input end of the negative pressure device 31, and control the negative pressure device 31 to close after the feedback unit receives the information that the number of pests detected by the scanning monitoring module 2 is lower than a lower limit.

[0050] By controlling the working band and brightness of the light source through the light control unit, the working state of the light module 1 can be dynamically adjusted according to actual needs, thereby improving the flexibility and adaptability of the system; through the cooperation of the feedback unit, the wavelength and brightness of the light module 1 can be dynamically adjusted according to the monitoring results, thereby further improving the detection and killing efficiency; after the air duct switch control unit scans the monitoring module 2 to determine the wavelength that attracts the most pests, it cooperates with the feedback unit to continuously feedback the number of pests near the light module 1, and uses the air duct switch control unit to open and close the negative pressure device 31 to attract and capture pests, thereby ensuring that the pests are effectively captured while avoiding excessive energy consumption.

[0051] When in use, first let the lighting module 1 release all colors of light in all bands, and then gradually rotate the light of different wavelengths from low to high at intervals of 30 minutes. The scanning monitoring module 2 scans under the lighting conditions of different wavelengths. The control module 4 records the scanning results, and after all wavelengths are rotated, compares the number of pests under the lighting conditions of the entire band to determine the wavelength that attracts the most pests. Then, let the lighting module 1 continue to work with the light of this wavelength. After the scanning monitoring module 2 detects that the number of nearby pests has reached the upper limit, the negative pressure device 31 is controlled to start, and an air duct is generated near the input end of the negative pressure device 31 to attract and capture pests. After the feedback unit receives the scanning monitoring module 2 that the number of pests is lower than the lower limit, the negative pressure device 31 is controlled to close, and the cycle continues.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
