Technical Field

[0001] The present invention relates to the technical field of harmful insect monitoring, in particular to a locust monitoring device based on sound signals and multi-modal automatic trapping functions. Background Art

[0002] Existing locust monitoring equipment usually uses light or pheromone to attract locusts. First, the attraction method is relatively simple, and there are problems such as unclear attraction effect and low number of attracted samples. Secondly, it can only monitor locusts by means of regulating locust behavior such as attraction, and cannot directly monitor naturally behaving locusts through non-regulatory means. There is still a lack of novel monitoring technologies, which leads to problems such as low sensitivity in monitoring locust occurrences and inaccurate results. Summary of the Invention

To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 6As shown, the present embodiment provides a locust monitoring device based on sound signals and multi-modal automatic trapping functions. The locust monitoring device based on sound signals and multi-modal automatic trapping functions of the present embodiment is a columnar vertical structure as a whole. Each structure is reasonably arranged, including: a base 105, a main body chassis 104, and a sound collection device connected to the main body chassis 104, a multi-modal trapping device, an image collection device 108, a data remote transmission device 304 and a power supply device. The sound collection device is used to collect sound signals of locusts around the device of the present embodiment and sound signals of the environment around the device of the present embodiment. The sound signal of the locust refers to the sound of the wing vibration, which is used to collect the time of the signal collection. The multimodal attracting device includes a light attracting structure 106, a sound attracting structure and a pheromone attracting structure 110. The light attracting structure 106 is used to emit a light signal that can attract locusts to the attracting area. The pheromone attracting structure 110 is used to release an odor signal that can attract locusts to the attracting area. The sound attracting structure is used to play a sound signal and a vibration signal that can attract locusts to the attracting area. The image acquisition device 108 can collect image signals of locusts in the attracting area. The power supply device and the sound acquisition device, the multimodal attracting device , the image acquisition device 108 and the data remote transmission device 304 are connected and used to power the sound acquisition device, the multimodal trapping device, the image acquisition device 108 and the data remote transmission device 304. The sound acquisition device and the sound trapping structure are all located above the main body chassis 104. The pheromone trapping structure 110 and the data remote transmission device 304 are all located inside the main body chassis 104. The base 105 is located below the main body chassis 104 and fixed to the ground. The light trapping structure 106, the pheromone trapping structure 110 and the sound trapping structure work together to encourage locusts to be lured to the trapping area, and then the image acquisition device 108 collects image signals of the trapping area. By analyzing the image signal, the density, age, category and other data of locusts in the trapping area are obtained, and based on the above data, the locust occurrence situation in the area where the device of this embodiment is located is judged. This embodiment uses both sound signals and image signals for monitoring and analysis, and is used to comprehensively analyze diversified data including locust occurrence density, category, direction, age, etc. from multiple angles to judge the locust occurrence situation in the area where the device of this embodiment is located. At the same time, the device of this embodiment can remotely transmit the analyzed data to cloud users through the data remote transmission device 304, and the user can automatically and accurately obtain the locust occurrence situation in the area where the device of this embodiment is located in real time without going to the monitoring site.

[0035] The locust monitoring device provided by this embodiment, which uses sound signals and multimodal automatic trapping, can achieve sound signal monitoring and multimodal trapping. Based on the sound signals, this embodiment uses a sound collection device to collect sound signals from locusts around the device and sound signals from the surrounding environment, such as wind noise, raindrops, birds, and other multiple environmental sound source signals, thereby forming monitoring samples of the locust sound signals and environmental sound signals. The monitoring samples are used to automatically analyze data such as time domain, frequency spectrum, and acoustic spectrum in real time to determine whether locusts have occurred and, if they have, their density, age, direction, and other data. Based on this data, the locust occurrence in the area where the device of this embodiment is located is accurately estimated. The sound signals of this embodiment are used to automatically update the real-time activity and changing trends of locusts in the area. Combined with time series data, peak periods of locust activity can be further predicted.

These functions work together to achieve the multimodal automatic trapping function that automatically attracts locusts around the device of this embodiment to the trapping area of the device of this embodiment. The image acquisition device 108 then captures image signals of the trapping area, thereby forming a monitoring sample of the image signals of the locusts trapped under the multimodal automatic trapping function. The monitoring sample is used to automatically analyze data such as the density, age, and category of the locusts in the captured image signals in real time. Based on this data, the occurrence of locusts in the area where the device of this embodiment is located is estimated.

[0037] Through the above two functions, the device of this embodiment can realize the functions based on sound signals and trapping, thereby receiving the sound signals of locusts around the device of this embodiment and the image signals of locusts trapped around, and using the two signals to jointly perform monitoring and analysis, so as to realize multi-angle comprehensive analysis of diversified data including locust occurrence density, category, direction, age, etc., and can more accurately, sensitively and efficiently estimate the locust occurrence situation in the area where the device of this embodiment is located. At the same time, the device of this embodiment can remotely transmit all analyzed data to cloud users through the data remote transmission device 304. Users can automatically and accurately obtain the locust occurrence situation in the area where the device of this embodiment is located in real time without going to the monitoring site and take protective measures in time before the locust outbreak, so as to strangle the locust disaster in the early stage of the outbreak, effectively reduce the losses caused by large-scale locust outbreaks, and avoid the large-scale use of chemical pesticides when locust disasters break out, protect the environment, and promote green development of agricultural prevention and control.

[0038] In some embodiments, the main chassis 104 is a vertical rectangular parallelepiped, and an openable main chassis door 301 is provided on the back of the main chassis 104. The interior of the main chassis 104 is divided into three layers: upper, middle, and lower. The upper layer of the main chassis 104 is provided with a main control board 302 and a data remote transmission device 304. The sound collection device, the image collection device 108, the multimodal trapping device, and the data remote transmission device 304 are all connected to the main control board 302. The main control board 302 can control the sound collection device, the image collection device 108, the multimodal trapping device, and the data remote transmission device 304. The main control board 302 is used to control the sound collection device to collect the sound signals of the locusts around the device of this embodiment and the sound signals of the environment around the device of this embodiment. The main control board 302 processes the collected sound signals of the locusts around and the sound signals of the environment around. The main control board 302 is used to control the light attracting structure 106 of the multimodal attracting device to emit a light signal that can attract locusts to the attracting area, the pheromone attracting structure 110 to release an odor signal that can attract locusts to the attracting area, and the sound attracting structure to play a sound signal and a vibration signal that can attract locusts to the attracting area. The main control board 302 is used to control the image acquisition device 108 to collect image signals of locusts attracted to the attracting area. The main control board 302 is used to analyze the collected image signals of locusts attracted to the attracting area. The main control board 302 is used to control the data remote transmission device 304 to remotely transmit the analyzed data to the cloud.

[0039] In some embodiments, two horizontal cantilevers extend from one side of the main chassis 104 of this embodiment, the upper horizontal cantilever is a light-attracting cantilever 107, and the lower horizontal cantilever is a photographing cantilever 109. The light-attracting cantilever 107 and the photographing cantilever 109 can extend to any side of the locust monitoring device based on sound signals and multi-modal automatic trapping function of this embodiment, and are not limited to the direction shown in the figure.

[0040] In some embodiments, since locusts move on the ground, the image acquisition device 108 is used to collect image signals toward the ground. The trapping area is the image acquisition area that can be covered by the image acquisition device 108. The image acquisition device 108 is installed at the end of the photographing cantilever 109 away from the main chassis 104, so that the image acquisition device 108 can better collect locust image signals in the trapping area. The camera 407 of the image acquisition device 108 is used to collect image signals toward the trapping area. The photographing cantilever 109 can move parallel to each other up and down to adjust the height of the image acquisition device 108. The control line 408 of the image acquisition device extends from the image acquisition device 108 along the internal space of the photographing cantilever 109 to the inside of the main chassis 104 and is connected to the power supply device and the main control board 302.

[0041] In some embodiments, the image acquisition device 108 includes a camera 407, and the camera 407 is located in the center and lower area between the light source of the light-attracting structure 106 and the spray point of the pheromone-attracting structure 110. A transparent baffle 111 that can cover the image acquisition device 108 is provided above the image acquisition device 108. The transparent baffle 111 is made of plastic and is used to prevent rain and shield. The transparent baffle 111 is located on the photographing cantilever 109. The transparent baffle 111 can be set to a circular shape, and the radius of the transparent baffle 111 is smaller than the length of the photographing cantilever 109.

[0042] In some embodiments, the light-inducing structure 106 is installed at one end of the light-inducing cantilever 107 away from the main chassis 104 to prevent the light signal emitted by the light-inducing structure 106 from being blocked. The light-inducing structure 106 is set directly above the image acquisition device 108 through the light-inducing cantilever 107. The light-inducing cantilever 107 can move parallel up and down to adjust the height of the light-inducing structure 106. The control line of the light-inducing structure 106 extends along the internal space of the light-inducing cantilever 107 into the main chassis 104 and is connected to the power supply device and the main control board 302.

[0043] In some embodiments, the light attractant structure 106 includes an insect attractant bulb, a light attractant controller, and a lampshade. The insect attractant bulb and the light attractant controller are both located inside the lampshade. The lampshade includes a metal frame to prevent the insect attractant bulb from being damaged by external forces. The wavelength of the insect attractant bulb includes a wavelength range of yellow light and a wavelength range of red light. The yellow light and red light of the insect attractant bulb can be controlled by the light attractant controller to flash simultaneously or at regular intervals, thereby more effectively attracting locusts. The light attractant controller has light control, rain control, and time control switches. On the one hand, it can control the duration and frequency of the illumination of the different wavelengths of the insect attractant bulb. On the other hand, it can also control the closing time of the overall light switch, so that the insect attractant bulb automatically turns off during the day or rainy days and automatically illuminates at night, saving energy. The light attractant structure 106 automatically attracts locusts around the device of this embodiment to the trapping area of the device of this embodiment by emitting light signals with wavelengths specific to locusts, and in conjunction with other trapping methods, centrally monitors locust occurrence.

[0044] In some embodiments, the pheromone attracting structure 110 includes a pheromone liquid tank 401, a pheromone controller 403, a sprayer 402 and a spray pipe 404. The pheromone liquid tank 401, the pheromone controller 403 and the sprayer 402 are all located in the lower layer inside the main body chassis 104. The pheromone liquid tank 401 is inside the main body chassis 104 and is detachably connected to the main body chassis 104. The pheromone liquid tank 401 is used to hold pheromone liquid and can attract locusts by the pheromone smell it emits. The pheromone liquid tank 401 is completely closed. A lower liquid outlet 406 is provided at the bottom of the pheromone liquid tank 401, and an upper liquid outlet 405 is provided at the top of the pheromone liquid tank 401. A spray port is provided on the photographing cantilever 109 and the spray port extends to the outside of the photographing cantilever 109. The upper liquid outlet 405 is connected to the spray pipe 404. The mist outlet is connected through a spray pipe 404, which extends along the internal space of the photographing cantilever 109 from the upper liquid outlet 405 to the spray outlet. The sprayer 402 is arranged at and connected to the lower liquid outlet 406. The sprayer 402 is a piezoelectric ceramic piece. The sprayer 402 is used to form the pheromone liquid in the pheromone liquid tank 401 into a pheromone spray that sprays upward. The pheromone spray can sequentially pass through the upper liquid outlet 405 of the pheromone liquid tank 401 and one end of the spray pipe 404 into the spray pipe 404 and be sprayed out from the spray outlet at the other end of the spray pipe 404. The pheromone controller 403 is used to control the working time and power of the sprayer 402. The spray outlet is arranged toward the trapping area. The spray outlet of the pheromone trapping structure 110 is arranged in parallel with the camera 407 of the image acquisition device 108. When the pheromone liquid in the pheromone liquid tank 401 is used up, the upper liquid outlet 405 and the lower liquid outlet 406 of the pheromone liquid tank 401 can be directly disconnected, and the pheromone liquid tank 401 can be taken out of the main chassis 104, and put back after filling or replacing. The upper liquid outlet 405 and the lower liquid outlet 406 can be reconnected to resume use, which is convenient for replenishing the pheromone liquid. The pheromone trapping mechanism 110 operates by transferring liquid from the pheromone tank 401 to the sprayer 402 at the bottom via the lower outlet 406. Powering the sprayer 402 causes the pheromone liquid to spray upward. The mist collects at the upper outlet 405 of the tank 401 and then flows through the spray pipe 404 to the spray port at the other end of the camera cantilever 109. The spray is then slowly released downward, releasing an odor signal that attracts locusts. This mechanism, in conjunction with other trapping methods, automatically attracts locusts around the device to the trapping area for centralized monitoring of locust infestations, allowing accurate prediction of locust infestations in the area where the device is located. A pheromone controller 403, connected to the sprayer 402, automatically timed the sprayer's operating time and power, controlling the release time and spray volume, thereby controlling the amount of pheromone released, enhancing efficiency and reducing pheromone liquid consumption.Traditional liquid pheromones are mainly released by soaking them in solid materials with gaps and then evaporate naturally to produce their effects. This embodiment releases pheromone liquid by spraying and can control its release time, frequency, and rate. Its efficiency is much higher than natural evaporation methods.

[0045] In some embodiments, it also includes a sound signal box 201 and a sound collection and playback box 202. The sound signal box 201 is installed above the main box 104 and is rotatably connected to the main box 104. The sound signal box 201 rotates around the axis of the main box 104 or forms a universal rotation with the main box 104.

[0050] This embodiment can achieve the following two functions:

[0051] Function 1: This embodiment can realize sound signal monitoring. Based on sound signals, this embodiment collects specific sound signals of locusts in the surrounding area and sound signals in the surrounding environment, such as wind noise, raindrops, birds, and other multiple environmental sound source signals through a sound collection device, thereby forming monitoring samples of locust-specific sound signals and environmental sound signals. Based on the monitoring samples, the device automatically analyzes the time domain, spectrum, and sound spectrum data in real time to determine whether locusts have occurred and the density, age, direction, and other data after they have occurred. Based on the above data, it is used to monitor the occurrence of locusts in the area where the device of this embodiment is located. The sound signals of this embodiment are used to automatically update the real-time activity status and change trends of locusts in the area. Combined with time series data, it further predicts the peak period of locust activity.

[0052] Function 2: This embodiment can achieve multimodal trapping. Based on the multimodal automatic trapping function, this embodiment uses a sound trapping mechanism to play a sound signal that can attract locusts, a pheromone trapping mechanism 110 to release an odor signal that can attract locusts, and a light trapping mechanism 106 to emit a light signal with a specific wavelength that can attract locusts. These functions work together to achieve the multimodal automatic trapping function. This multimodal automatic trapping function automatically attracts locusts around the device to the trapping area of the device of this embodiment. The image acquisition device 108 then photographs the trapping area and captures image signals, thereby forming a monitoring sample of the image signals of the locusts trapped by the multimodal automatic trapping function. Based on the monitoring sample, the captured image signals are automatically analyzed in real time to determine data such as the density, age, and type of locusts. This data is then used to estimate the locust infestation in the area where the device of this embodiment is located.

[0053] Through the above two functions, this embodiment can realize the combined effect of the two functions based on sound signals and multimodal automatic trapping to monitor the occurrence of locusts. On the one hand, this embodiment receives the sound signals of locusts around the device of this embodiment and the sound signals of the surrounding environment. On the other hand, it obtains the image signals of the locusts trapped in the trapping area, thereby using the two signals to form a monitoring sample for joint monitoring and analysis, making the monitoring sample more sensitive, timely and specific, and thus making the monitoring data obtained based on the monitoring sample more accurate, so that users can effectively take prevention and control measures in time in the early stage of locust occurrence, providing an opportunity to effectively prevent large-scale locust outbreaks. At the same time, because the monitoring samples have the characteristics of diversified sound and image information, the monitoring samples obtained according to the present invention can monitor the diversified data of the area where the device of this embodiment is located, including locust occurrence density, type, direction, age, etc., and thus can more accurately, sensitively and efficiently estimate the locust occurrence situation in the area where the device of this embodiment is located. At the same time, the device of this embodiment can remotely transmit all analysis data to the end user through the data remote transmission device 304. The user can automatically and accurately obtain the locust occurrence situation in the area where the device of the present invention is located in real time without going to the monitoring site and take protective measures in time before the locust outbreak, so as to strangle the locust disaster in the early stage of the outbreak, effectively reduce the losses caused by large-scale locust outbreaks, and avoid the large-scale use of chemical pesticides when locust disasters break out, protect the environment, and promote green development of agricultural prevention and control.

[0054] This embodiment has the following advantages:

[0055] By introducing the sound signals of locusts and the sound signals in the surrounding environment, such as wind noise, raindrops, birds and other multiple environmental sound source signals, a monitoring sample of locust-specific sound signals and environmental sound signals is formed, making the monitoring samples more diverse. The comprehensive analysis of the monitoring samples is more accurate in the occurrence of locusts. In addition, the monitoring accuracy is improved while the monitoring ability is improved under the interference conditions of multiple sound signals, ensuring the reliability of the equipment in complex environments, providing acoustic data support for scientific research on pest control and ecological control, introducing the concept of sustainable agricultural control, and promoting the development of green agriculture.

[0056] The multi-modal automatic trapping function combines sound signals, pheromone signals, and light signals to enhance the trapping range, improve the trapping sensitivity, and increase the trapping rate, thereby forming a monitoring sample of locust image signals trapped under the multi-modal automatic trapping function, making the monitoring sample more representative and the monitoring data obtained from the analysis of the monitoring sample more accurate;

[0057] This embodiment can realize the combined effect of sound signals and multimodal automatic trapping to monitor locust occurrences. The sound signals of locusts and the environment and the image signals of locusts under multimodal automatic trapping are combined to form monitoring samples for monitoring and analysis. This makes the monitoring samples more sensitive, timely, and specific. At the same time, it also has the characteristics of diversified sound and image information, and has high specificity for monitoring locusts. In turn, the monitoring data obtained based on the monitoring samples is more accurate. From multiple angles, more sensitive, accurate, and efficient data analysis can be comprehensively obtained. This allows users to effectively formulate more targeted prevention and control measures in the early stages of locust outbreaks, reducing unnecessary waste of resources.

[0058] The device of this embodiment can remotely transmit all monitoring and analysis data to end users through the data remote transmission device 304. Users can automatically and accurately obtain the locust occurrence situation in the area where the device of the present invention is located in real time without having to go to the monitoring site. They can take timely protective measures before a locust outbreak occurs, thus strangling the locust disaster in the early stage of the outbreak, effectively reducing the losses caused by large-scale locust outbreaks, and avoiding the large-scale use of chemical pesticides during locust outbreaks, thereby protecting the environment and promoting green development of agricultural prevention and control.

[0059] By adopting this embodiment, timely monitoring and measures can be taken in the early stages of locust outbreaks, which can effectively suppress the losses caused by large-scale locust outbreaks and avoid environmental pollution caused by large-scale use of chemical pesticides during locust outbreaks, thereby protecting the environment and promoting green development of agricultural prevention and control.

[0060] The monitoring effect of the locust monitoring device based on sound signals and multi-modal automatic trapping function of this embodiment is demonstrated through comparative experiments below.

[0061] Comparative test 1:

[0062] A locust trapping test was conducted using the locust monitoring device based on sound signals and multi-modal automatic trapping function of this embodiment, and a locust trapping test was conducted under blank natural conditions as a control.

[0063] The experimental method involves selecting a space that resembles the natural conditions of a locust breeding area and dividing it equally into two identical, enclosed, dimly lit square spaces, A and B, each with a projected area of 100 square meters. 100 locusts of the same age are dispersed into each space, with a preset population density of 1 locust per square meter. Temperature, humidity, and other objective conditions in both spaces are maintained consistent. The locust monitoring device, which utilizes acoustic signals and multimodal automatic trapping, is placed in the center of each space.

[0064] All the trapping and photographing functions of the locust monitoring device based on sound signals and multimodal automatic trapping functions of this embodiment placed in space A were activated, namely, the sound trapping mechanism, light trapping mechanism, and pheromone trapping mechanism, and the image acquisition device function was simultaneously activated. At the same time, only the photographing function of the locust monitoring device based on sound signals and multimodal automatic trapping functions of this embodiment placed in space B was activated, while all its trapping functions were disabled, to simulate blank natural conditions. The image acquisition device was used to take photos every two hours for six hours. The number of locusts in the images captured by the photographing function was used to determine the automatic trapping effectiveness of the multimodal automatic trapping function in space A compared to the blank natural conditions in space B. Based on the trapping effectiveness, the device was then verified to have the function of forming a monitoring sample, thereby verifying its ability to estimate locust occurrences and its accuracy and representativeness in the monitoring sample, thereby evaluating the accuracy of locust monitoring by the locust monitoring device based on sound signals and multimodal automatic trapping functions of this embodiment.

[0065] The test results are as follows:

[0066] Trial duration 2h 4h 6h A space (number of shots) 36 42 48 B space (number of shots) 0 1 0

[0067] The test results show that the number of locusts trapped by the locust monitoring device based on sound signals and multimodal automatic trapping function of the present embodiment is significantly higher than that of the blank control. When there is no trapping function to actively regulate the behavior of locusts, a total of 1 locust is trapped in the three time periods, with an average of 0.33 locusts per time period, and a maximum trapping rate of 1%. Basically, no locusts can be trapped and photographed, and no effective monitoring sample can be formed for photographing and analysis. However, when the present invention uses the multimodal automatic trapping function, a total of 126 locusts are trapped in the three time periods, with an average of 42 locusts per time period, and a maximum trapping rate of 48%. This proves that locusts can be effectively regulated to produce specified aggregation behavior, and locusts can be automatically lured to the trapping area of the present invention and photographed to form a monitoring sample. By analyzing the monitoring sample, it can be proved that the device can realize the function of estimating the occurrence of locusts in the area where the device of the present invention is located.

[0068] Comparative test 2:

[0069] A locust trapping test was conducted using the locust monitoring device based on sound signals and multi-modal automatic trapping functions of this embodiment, while a locust trapping test was conducted using light trapping as a comparative example.

[0070] The experimental method involves selecting a space that resembles the natural conditions of a locust breeding area and dividing it equally into two identical, enclosed, dimly lit, square spaces, each with a projected area of 100 square meters. 100 locusts of the same age are dispersed into each space, ensuring a population density of 1 locust per square meter. Temperature, humidity, and other objective conditions in both spaces are maintained consistent. The locust monitoring device, based on acoustic signals and multimodal automatic trapping, according to this embodiment, is placed in the center of each space.

[0071] All the trapping and photographing functions of the locust monitoring device based on sound signals and multimodal automatic trapping functions of the present embodiment placed in space A were activated, namely, the sound trapping mechanism, light trapping mechanism, and pheromone trapping mechanism, and the image acquisition device function was simultaneously activated. At the same time, only the photographing and light trapping functions of the locust monitoring device based on sound signals and multimodal automatic trapping functions of the present embodiment placed in space B were activated to simulate conditions where only light trapping was used to trap locusts. The image acquisition device was used to take photos every two hours for six hours. The number of locusts in the images captured by the photographing function was used to determine the automatic trapping effectiveness of the multimodal automatic trapping function in space A compared to the light trapping function in space B. Based on the trapping effectiveness, the sensitivity and representativeness of the monitoring samples formed were verified to evaluate the accuracy of the locust monitoring system of the present invention.

[0072] The test results are as follows:

[0073] Trial duration 1h 2h 3h 4h 5h 6h A (number of shots) 30 36 37 42 42 48 B (number of shots) 11 11 12 10 13 11

[0074] The test results show that:

[0075] First, the locust monitoring device based on sound signals and multimodal automatic trapping functions of the present embodiment traps locusts significantly faster than the comparative example using only light trapping functions. Under the multimodal automatic trapping function of the present invention, the cumulative number of locusts trapped per hour is 235, with an average of 39.17 per hour, of which 103 are trapped in the first three hours. When the light trapping function is used alone, the cumulative number of locusts trapped per hour is 68, with an average of 11.33 per hour, of which 34 are trapped in the first three hours. This demonstrates that the monitoring samples formed by the locust monitoring device based on sound signals and multimodal automatic trapping functions of the present embodiment are superior to those formed by the simulated embodiment using only a single trapping function. On the one hand, the total number and average value of the number of locusts trapped are both higher, and the number of locusts trapped in a short period of time (the first three hours) is higher. This demonstrates that the monitoring samples formed by the present embodiment are more sensitive and more timely, making the monitoring data obtained based on the monitoring samples more accurate, enabling users to effectively take preventive measures in the early stages of locust infestations, providing an opportunity to effectively prevent large-scale locust outbreaks. It is further proved that the data monitored by the monitoring samples formed according to this embodiment can more sensitively, accurately and efficiently predict the occurrence of locusts in the area where the device of the present invention is located, thereby timely and effectively suppressing locust disasters and protecting the ecological environment.

Temperature, humidity, and other objective conditions in both spaces are maintained consistent. The locust monitoring device, based on acoustic signals and multimodal automatic trapping, according to this embodiment, is placed in the center of each space.

At the same time, only the photographing and pheromone trapping functions of the locust monitoring device based on sound signals and multimodal automatic trapping functions of this embodiment placed in space B were activated to simulate conditions where locusts were trapped using only pheromone trapping. The image acquisition device was used to take photos every hour for six hours. The number of locusts in the images captured by the photographing function was used to determine the automatic trapping effectiveness of the multimodal automatic trapping function in space A compared to the pheromone trapping function in space B. Based on the trapping effectiveness, the sensitivity and representativeness of the monitoring samples formed were verified to evaluate the accuracy of the locust monitoring system of the present invention.

[0080] The test results are as follows:

When using only pheromone trapping, the total of 55 locusts trapped per hour is averaging 9.17 per hour, with a total of 17 in the first three hours. This demonstrates that the monitoring samples generated by the locust monitoring device based on sound signals and multimodal automatic trapping are superior to those generated by the simulated example using only trapping. This demonstrates that the monitoring samples generated by this embodiment are more sensitive and timely, as both the total number and average number of locusts trapped are higher, and the number of locusts trapped in a short period of time (the first three hours) is higher. This makes the monitoring data obtained based on these monitoring samples more accurate, enabling users to effectively take preventive measures in the early stages of locust infestations, providing an opportunity to effectively prevent large-scale locust outbreaks. It is further proved that the data monitored by the monitoring samples formed according to this embodiment can more sensitively, accurately and efficiently predict the occurrence of locusts in the area where the device of the present invention is located, thereby timely and effectively suppressing locust disasters and protecting the ecological environment.
