Description

Technical Field

[0001] This invention relates to the field of insect control technology, specifically to a synergistic insect-attracting device that combines a frequency-tunable UV LED with controllable attractant volatilization. Background Technology

[0002] Currently, in many fields such as agriculture, forestry, warehousing and logistics, and landscaping, the control of harmful insects still largely relies on traditional chemical pesticide application methods. This over-reliance on chemical control has led to a series of serious ecological and environmental problems, including but not limited to excessive pesticide residues in agricultural products, long-term damage to soil structure and fertility, pollution of groundwater and surface water, increasing pesticide resistance in pest populations, and the inevitable harm to a large number of beneficial natural enemy insects during the control process, thus disrupting the ecological balance. Driven by both this real challenge and environmental protection needs, green and environmentally friendly physical insect-trapping technologies that integrate specific spectral attraction and biopheromone odor attraction principles are gradually becoming the mainstream development trend in research and application in this field. Currently, the core methods of green physical insect-trapping technologies recognized and used in the industry mainly focus on using insecticidal lamps of specific wavelengths for pure light attraction, or composite insect-trapping devices that simply combine light with chemical / biological attractants.

[0003] However, several significant technical bottlenecks and limitations exist in the practical application of the aforementioned technologies. In the light attraction section, existing devices typically only allow switching between different light wavelengths (colors), but their emission frequency remains fixed. This fails to precisely match the physiological differences in the tendency of different pest species to respond to specific flashing frequencies (usually in the Hertz range). This frequency mismatch directly leads to poor selectivity in the insect attraction process: on the one hand, the attraction efficiency for target pests is unsatisfactory; on the other hand, it mistakenly attracts a large number of beneficial insects, creating a situation where "enemy cannot be distinguished." Simultaneously, fixed-frequency light often means higher energy consumption, and its effective range is relatively limited, ultimately resulting in low overall trapping efficiency. In the attractant release section, currently, rubber or silicone lures are commonly used, releasing odors through passive, slow-release methods. This release method relies entirely on passive adjustment based on changes in ambient temperature, and cannot intelligently respond according to the diurnal rhythm or seasonal peaks of pest activity—that is, actively increasing the release amount during peak pest activity to enhance attraction and reducing the release amount during off-peak periods to save costs. This "one-size-fits-all" release mode not only results in a large waste of the attractant and significantly shortens the effective duration of a single fill, but also makes it difficult to form a sufficiently rich and stable odor concentration gradient over long distances, resulting in a weak synergistic effect between the attractant and the photoinducible part.

[0004] More critically, in existing technologies, the light-attracting components and the attractant-releasing components are typically designed and operate independently, lacking a "synergistic mechanism" based on pest behavior patterns. They are asynchronous in terms of activation time, operating frequency (such as the rhythm of light flashing and odor pulses), and action step length, failing to create a synergistic effect where "1+1>2." This disconnect significantly reduces the synergistic gain of the technology, limits the expansion of the effective attraction radius, and has a very limited impact on improving overall efficiency. Furthermore, the entire system generally lacks a closed-loop adaptive control mechanism based on real-time feedback. When external environmental conditions, such as ambient light intensity, temperature, and humidity, change, the device's operating parameters cannot be dynamically adjusted and compensated for. This often manifests as: the effect is acceptable in the initial installation phase or when the environment is suitable, but once the environment changes, the insect-attracting effect rapidly diminishes. The inability to optimize light-attracting parameters (such as intensity and frequency) and attractant release rate based on environmental feedback leads to poor equipment stability, short-lasting effects, and a relatively short lifespan, making it difficult to meet the needs of long-term, stable, and efficient green pest control. Summary of the Invention

[0028] The intelligent main control system includes a core processing unit, a control panel, a cover plate, and a base.

[0029] The base is a rectangular columnar structure with an I-shaped cross-section, consisting of a top plate, web columns, and a bottom plate.

[0032] The core processing unit faces away from the control panel and is mounted together with the control panel.

[0033] The core processing unit and control panel are mounted inside the display opening of the base, with the control panel facing outwards.

[0034] The energy storage battery is installed below the control panel and is electrically connected to the core processing unit.

[0035] The biological bait controllable odor volatilization module and annular air guide coupling assembly include a mounting frame, annular air guide device, electric air conditioning valve, bait box, temperature control heating assembly, and low-noise micro fan.

[0036] The mounting bracket includes a first mounting plate, a second mounting plate, and four supports.

[0037] The first mounting plate and the second mounting plate are placed opposite each other and are mounted together by four brackets.

[0038] The four brackets are respectively installed at the four corners of the first mounting plate and the second mounting plate.

[0039] The support is a hollow columnar structure.

[0040] The first mounting plate has a threaded hole III at its center that matches the first step of the light source module base.

[0041] The second mounting plate of the mounting bracket is fixedly mounted on the top of the base.

[0050] The annular air guide device is placed above the attractant box and is fastened to the hole in the base.

[0051] The air generated by the low-noise micro fan passes through the attractant box, producing an airflow carrying the scent of the biological bait. After passing through the ventilation slot I of the annular air guide device, the airflow carrying the scent of the biological bait becomes an annular airflow carrying the scent of the biological bait.

[0052] The first step of the light source module base is threadedly installed at the threaded hole III of the first mounting plate of the mounting bracket.

[0053] The sensor assembly is mounted on the first mounting plate of the mounting bracket.

[0054] The solar power panel is mounted above the sensor assembly.

[0055] Furthermore, the LED driver board is connected to the core processing unit via a first cable.

[0075] The protective cover is made of materials including quartz.

[0076] The LED beads include UV LEDs.

[0077] The technical effects of this invention are undeniable, and its beneficial effects include:

[0078] 1. Stroboscopic bionic light-attracting technology can significantly improve induction efficiency. This invention utilizes a multi-band UVLED array, combined with a fully adjustable stroboscopic frequency and duty cycle design, to biomimetically simulate the sensitivity of the compound eye visual nerves of different pests to flashing light. The light stimulation intensity generated by dynamic flashing is far higher than that of traditional constant-brightness light sources, thereby greatly enhancing the phototactic activity of pests and effectively extending the attraction distance. Simultaneously, through differentiated parameter settings, while strengthening the attraction of target pests, it can significantly reduce the false attraction rate of natural enemies and beneficial insects, achieving precise induction and control.

[0079] 2. The multi-dimensional synergistic mechanism of light and odor significantly improves insect attraction efficiency. This invention spatially couples a controllably released attractant with a dynamic stroboscopic light source, achieving the superposition and synergistic effect of light and odor signals. This combined effect of dual attraction modes, compared to traditional devices relying solely on a single light source or odor, generates a stronger overall attraction, increasing overall insect attraction efficiency by over 75% and resulting in a more significant trapping effect.

[0080] 3. The bait utilizes long-lasting sustained-release technology, effectively extending its effective period. The system integrates a dual closed-loop sustained-release structure with temperature control and valve control. This design precisely manages the release rate of the attractant's active ingredients, avoiding effectiveness loss due to rapid evaporation. This extends the bait's effective action time to more than three times the original duration, significantly reducing the frequency of bait replacement and decreasing maintenance costs and workload.

[0081] 4. The system possesses full-parameter intelligent adaptive capabilities, enabling unattended operation. By collecting real-time field data through environmental sensors and accessing a built-in pest characteristic parameter library, the system can automatically link and optimize light source operating parameters (such as wavelength, strobe, and intensity) and odor release parameters. It can automatically start and stop according to diurnal rhythms and dynamically adjust in a closed-loop manner based on environmental changes, thus flexibly adapting to complex and ever-changing application conditions in the field.

[0174] Working principle: The overall structure of this device is based on a vertical, columnar, waterproof outer shell, which integrates multiple functional modules, mainly including a modulated strobe UVLED array light source module, a biological bait controllable odor emission module, a ring-shaped air-guiding coupling component, an intelligent main control system, and a solar power supply module. These modules work together to achieve efficient and precise pest trapping.

[0175] Modular strobe UVLED array light source module: This module is located at the center of the upper part of the machine body, and its core is a cylindrical aluminum-based heat dissipation substrate with a diameter of 120mm. The circumference of the substrate is evenly divided into four independent sections, each densely packed with ultraviolet LED beads with wavelengths of 365nm, 385nm, 395nm, and 405nm, with eight beads precisely installed in each section. The beads are attached to the side wall of the cylinder, radiating only in all directions, with no ineffective upward emission, forming a surrounding conical light field, which shares the same cylindrical space as the lower layer of odor volatilization; the light field and odor field are in the same layer, with the same radius, and are completely coupled in three dimensions, resulting in the strongest synergistic insect-attracting effect.

[0176] This module supports flexible on / off combinations of the ultraviolet band. The main control system controls four independent PWM signals, enabling stepless adjustment of the LED beads via the back-end MOS driver board. By controlling the PWM frequency, the LED bead frequency can be adjusted within a wide range from 1Hz to 60Hz. Adjusting the PWM duty cycle allows for brightness adjustment between 10% and 90%. Furthermore, it supports various complex lighting modes, including independent flickering of single-band LED beads, synchronous flickering of multi-band LED beads, and interleaved asynchronous flickering of multi-band LED beads.

[0177] The module is covered by a high-transmittance quartz protective cover, which effectively prevents dust while ensuring near-loss-free transmission of ultraviolet light. It emits light from the side in a 360° direction, perfectly matching the flight behavior of pests that spiral around the light source. The module's working principle is based on the phototactic effect of insect compound eyes on specific dynamic flashing light waves. Compared to traditional constant-brightness light sources, this dynamic strobe light significantly enhances the visual stimulation and attraction effect on pests.

[0178] Controllable Odor Evaporation Module for Biological Bait: This module is located below the light source module and is sealed inside with a composite biological bait scientifically formulated from plant volatiles, insect pheromones, and food-attracting active ingredients. The module incorporates a PTC micro-temperature control heating element and an electric air regulating valve. The opening of the electric regulating valve can be linearly adjusted between 0% and 100%. By precisely controlling the heating temperature of the chamber and the opening of the evaporation vents—two key parameters—through the acquisition of information such as ambient temperature and system time, dual closed-loop regulation of the odor evaporation rate and release flow rate is achieved. This design ensures that the bait odor is released slowly and consistently, significantly reducing the bait consumption rate and effectively extending the effective attraction cycle after a single filling.

[0179] Annular Airflow Coupling Component: This component features a cleverly designed modular sandwich structure, integrating a low-noise micro fan and an annular airflow channel surrounding the device. The air outlet is angled outwards. When the fan starts, it generates a stable and directional annular airflow. This airflow effectively traps the odor molecules of the biological bait released from the lower volatile module, promoting their rapid diffusion into the surrounding space. Simultaneously, the airflow completely covers and envelops the entire ultraviolet radiation area generated by the upper light source module. This design achieves complete coupling and overlap of the dynamic stroboscopic light field and the odor diffusion field in three-dimensional space, allowing the light and odor signals to diffuse synchronously and synergistically in all directions. This significantly expands the effective attraction radius of the device, achieving a synergistic effect across the entire domain of visual and olfactory attraction signals.

[0180] Intelligent Control System: This system uses a high-performance STM32 series microcontroller as its core processing unit, and is externally connected to temperature and humidity sensors and light sensors for monitoring environmental conditions. The system has a pre-installed database of parameters specific to various agricultural and forestry pests. This database stores optimal operating parameters for different target pests, including optimal strobe frequency, pulse duty cycle, ultraviolet band combination, light intensity, and matching odor release parameters. The system can automatically determine day and night based on ambient light intensity, thereby controlling the device's start and stop. It can also automatically retrieve the optimal collaborative operating parameters from the database based on real-time collected ambient temperature and humidity data, the activity patterns of different pests, and user-defined target pest types. The system synchronously adjusts the strobe mode of the light source module and the release status of the odor emission module, and fine-tunes the parameters in real time based on feedback data from the odor flow sensor, achieving fully unattended adaptive operation. For user convenience, the system also has an external display screen and function buttons, allowing users to manually view the status or change relevant parameter settings as needed.

[0181] Solar Power Module: To achieve long-term stable operation in outdoor environments without mains power, a high-efficiency 10W monocrystalline silicon solar photovoltaic panel has been successfully fabricated on the top of the device. The bottom of the device is equipped with a 12V / 5Ah lithium battery and a high-efficiency charge / discharge voltage regulation and protection circuit. The entire power supply system adopts a low-voltage DC scheme, allowing the battery to be charged by the solar panel during the day and powered by the battery at night or on cloudy days, ensuring continuous operation around the clock. The overall design emphasizes low power consumption, ensuring safety and meeting energy-saving and environmental protection requirements.

[0182] In addition, this embodiment also provides a complete collaborative insect-attracting method. This method achieves efficient insect-attracting operations throughout the entire process, from environmental perception and parameter decision-making to precise execution, through the temporal linkage of various functional modules, adaptive matching of working parameters, spatial coupling of light and odor fields, and closed-loop dynamic adjustment based on sensor feedback.

[0183] The specific workflow is as follows: After the device is powered on, it first initializes, and each functional module enters standby mode; the power supply module completes energy storage and stabilizes the output voltage. Subsequently, the intelligent main control system begins to collect ambient light intensity, temperature, and humidity data to determine whether it is daytime or nighttime working period, and, in conjunction with user-preset or automatically identified target pest types, retrieves the optimal collaborative working parameters from the built-in database. Next, the main control system drives the modulated stroboscopic UVLED array light source module to output a specific combination of ultraviolet bands, suitable light intensity, optimized stroboscopic frequency, and precise pulse duty cycle that matches the target pest, thereby generating a highly efficient dynamic stroboscopic insect-attracting light source. Simultaneously, the system synchronously controls the controllable odor volatilization module of the biological bait, sets the corresponding heating temperature, and adjusts the electric valve to a suitable opening, releasing targeted biological attractant odors at a constant rate. Immediately afterwards, the annular air-guiding coupling component is activated, and the directional circulation it generates tightly couples the dynamic stroboscopic light field with the released odor diffusion field, constructing a large-scale, light-odor synergistic composite attraction space. The target pests are attracted to the device by the combined visual stimulation of the dynamic strobe lights and the olfactory attraction of specific biological odors. Throughout the operation, temperature and humidity sensors, environmental sensors, and other components provide real-time feedback of operational data to the main control system. Based on this data, the system dynamically adjusts the strobe parameters of the light source and the odor volatilization parameters to maintain optimal insect attraction and adapt to environmental changes. When the ambient light intensity reaches a certain level during the day, the entire machine automatically enters a sleep state to save energy.

[0184] Example 12:

[0185] A synergistic insect-attracting device combining frequency-tunable UV LEDs and controllable attractant volatilization, the main technical details of which are described in Example 11, further elaborated in a confined space setting.

[0186] This system is suitable for controlling pests such as rice moths, grain beetles, and weevils in warehouse environments. The light source parameters are set to a combination of 395nm and 405nm wavelengths, with a light intensity of 70%, a strobe frequency of 10Hz, a duty cycle of 40%, and an asynchronous interleaved strobe mode to enhance stimulation. The odor module uses grain-based bait, with the valve opening set to 30% to achieve long-lasting, slow release under low airflow conditions. Simultaneously, the air guide fan is adjusted to low airflow operation to adapt to the limited airflow circulation conditions within the enclosed space of a warehouse, thereby achieving highly accurate pest attraction in this specific environment.

[0187] Example 13:

[0188] A synergistic insect-attracting device combining frequency-tunable UV LEDs and controllable attractant volatilization, the main technical details of which are described in Example 11, further applies to broad-spectrum field applications.

[0189] Addressing the complex situation of multiple pests (such as stem borers and bollworms) occurring together in farmland, this system employs a three-band hybrid LED array (365nm, 385nm, and 395nm) with an adaptive dynamic switching strobe frequency ranging from 8Hz to 25Hz. The duty cycle is also dynamically adjusted to cover a broader spectrum of pest tropism. The bait utilizes broad-spectrum composite biological pheromones. The odor module implements a diurnal temperature control strategy, increasing evaporation intensity at night and decreasing it in the early morning. The ventilation fan operates at full capacity to expand the odor diffusion coverage. This entire system works collaboratively to achieve broad-spectrum, highly efficient attraction and control of various pests in the field.
