Description

Technical Field

[0001] This invention relates to the field of disease prevention and control technology, and more specifically, to a mosquito oviduct with an early warning function. Background Technology

[0002] Aedes aegypti and Aedes albopictus are the main vectors of diseases such as dengue fever, chikungunya, and yellow fever, posing one of the most important public health problems in my country and the world. Therefore, using mosquito traps to capture Aedes mosquitoes and monitoring the captured (pregnant) mosquitoes to establish a comprehensive disease surveillance and risk assessment system is an effective method for evaluating the public health impact of Aedes mosquitoes as vectors.

[0003] In related technologies, mosquito traps and ovipositors are deployed in pre-defined areas to trap Aedes mosquitoes. The detailed location information of these traps is recorded, and technicians regularly observe and monitor the data, including the number of mosquitoes trapped or the number of eggs caught, for example every four days. Monitoring of Aedes mosquitoes is based on these observations. However, this monitoring method suffers from several drawbacks. Due to complex environmental conditions, such as in mosquito-rich southern regions where heavy rains and monsoons can cause ovipositors to overturn and become ineffective, the traps are rendered unusable for monitoring, impacting efficiency. Furthermore, technicians must regularly visit the areas where the traps are deployed, collect data, and replace ineffective traps, resulting in high costs and low efficiency in monitoring Aedes mosquitoes. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a mosquito oviduct with an early warning function to improve monitoring efficiency.

[0005] In a first aspect, embodiments of the present invention provide a mosquito egg attractor with an early warning function, comprising: a box top cover, a attractor body, and a monitoring circuit board, wherein... The inner wall of the box top cover is provided with internal threads, and the upper outer wall of the trap body is provided with external threads. The box top cover is fixed to the upper part of the trap body through the internal and external threads. On the top cover of the box, facing the body of the trap, there are one or more mosquito-attracting tubes that extend into the body of the trap. The top cover of the box also has a movable groove, and the mosquito-attracting tubes are located below the movable groove. The movable groove is equipped with a movable door and a movable door driver, with each movable door corresponding to a movable door driver. Inside the bottom of the trap body, there is a first protrusion extending upward for Aedes mosquitoes to lay eggs or rest, and a second protrusion containing an attractant to attract Aedes mosquitoes. The second protrusion is located above the first protrusion. The second protrusion and the first protrusion are offset from each other or partially overlap in projection. Below the external thread of the trap body, there is a third protrusion protruding towards the center of the trap body. The monitoring circuit board has a cylindrical hole corresponding to the mosquito-attracting tube on the top cover of the box. The mosquito-attracting tube passes through the cylindrical hole, and the monitoring circuit board is fixed on the third protrusion. The monitoring circuit board includes an ultrasonic water level detection module, a 3D attitude detection module, a microprocessor, a geolocation module, and a 4G communication module. The ultrasonic water level detection module is set on the monitoring circuit board at the position corresponding to the water surface. It emits ultrasonic waves according to the water level monitoring cycle preset by the microprocessor, acquires the ultrasonic waves reflected back from the water surface, encapsulates the emitted ultrasonic wave information and the received ultrasonic wave information in the first water level monitoring information, and sends it to the microprocessor. The microprocessor is used to process the received first water level monitoring information and the preset water level threshold. If the water level determined by the received first water level monitoring information exceeds the upper water level threshold, it sends a geographical location acquisition command to the geographical location module and sends water level exceeding upper limit information to the 4G communication module. The 3D posture detection module is used to detect the placement status information of the mosquito and egg attractant according to the posture detection cycle preset by the microprocessor, and send the placement status information to the microprocessor. The microprocessor is also used to determine whether the mosquito trap or ovipositor has been overturned based on the received placement status information. If it is determined that it has not been overturned, no action is taken. If it is determined that it has been overturned, a location acquisition command is sent to the geolocation module and an abnormal placement information of the mosquito trap or ovipositor is output to the 4G communication module. The geolocation module obtains the location information of the mosquito and egg attractor based on the received geolocation acquisition command, and sends the location information to the 4G communication module; The 4G communication module sends the received location information and water level exceeding the upper limit information to a pre-set server, or sends the received location information and trap placement abnormality information to a pre-set server.

[0006] Optionally, the monitoring circuit board is fixed to the third protrusion by welding or adhesive.

[0007] Optionally, clean water is filled into the space below the height of the first protrusion in the body of the trap, and filter paper is used to wrap the top of the first protrusion and extend along the direction from the top to the bottom of the first protrusion to contact the clean water.

[0008] Optionally, a water pumping hole is provided on the side wall of the trap body near the bottom, which connects to the water surface inside the trap body. A water pumping switch and a switch controller are provided on the outer side wall of the water pumping hole. After determining that the water level exceeds the upper threshold based on the received first water level monitoring information, the microprocessor is also used to output a pumping command to the switch controller so that the switch controller can open the pumping switch to drain water.

[0009] Optionally, the ultrasonic water level detection module is further configured to emit ultrasonic waves according to a preset water level monitoring cycle and then emit ultrasonic waves according to a preset water level monitoring sub-cycle, acquire the ultrasonic waves reflected back from the water surface, encapsulate the emitted ultrasonic wave information and the received ultrasonic wave information in a second water level monitoring information, and send them to the microprocessor. The microprocessor is also used to process the received second water level monitoring information and the preset lower water level threshold. If the water level determined by the received second water level monitoring information is lower than the lower water level threshold, it sends a sub-cycle termination command to the ultrasonic water level detection module to stop the ultrasonic water level detection module from emitting ultrasonic waves according to the preset water level monitoring sub-cycle. It also outputs a water stop command to the switch controller to close the pumping switch and seal the pumping hole.

[0010] Optionally, the ultrasonic water level detection module includes: a microelectromechanical system (MEMS) ultrasonic transmitter, a receiving element, and a driving circuit, wherein, The drive circuit is used to provide power to the ultrasonic transmitter and receiver components of the microelectromechanical system. A microelectromechanical system ultrasonic transmitter is used to emit ultrasonic waves according to a pre-set water level monitoring sub-cycle. The receiving element is used to receive the echo information of the ultrasonic wave emitted by the ultrasonic transmitter of the microelectromechanical system, encapsulate the emitted ultrasonic wave information and the echo information to obtain the second water level monitoring information, and send it to the microprocessor.

[0011] Optionally, the monitoring circuit board further includes a mosquito entry detection module, wherein... The microprocessor is also used to output detection instructions to the mosquito entry detection module according to the preset infrared detection cycle, obtain the number of the first mosquitoes entering the mosquito trap based on the received light intensity information and the transmitted light intensity information, and send the obtained number of the first mosquitoes to the 4G communication module. When a mosquito enters the detection module, which is positioned directly opposite the mosquito trap on the monitoring circuit board, it receives a detection command and then acquires the received infrared light intensity information and the emitted infrared light intensity information through infrared transmission and reception. The received light intensity information and the emitted light intensity information are then sent to the microprocessor. The 4G communication module will also send the initial mosquito count and current timestamp received from the microprocessor to a pre-set server.

[0012] Optionally, the monitoring circuit board further includes: The first image module is set at the position of the monitoring circuit board facing the mosquito trap. After receiving the detection command sent by the microprocessor, it takes an image of the mosquito trap and sends the captured image information to the microprocessor. The microprocessor is also used to identify the second mosquito count information contained in the image information based on the received image information and a pre-built mosquito identification model. If the error between the second mosquito count information and the first mosquito count information is within a preset error range, no processing is performed. If the error between the second mosquito count information and the first mosquito count information exceeds the preset error range, the image information is sent to the 4G communication module. The 4G communication module is also used to send the received image information to a pre-set server.

[0013] Optionally, the top cover of the box, except for the mosquito-attracting tube, is made of light-blocking material, while the body of the trap and the mosquito-attracting tube are made of transparent material.

[0015] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

It should be understood that the following drawings only show some embodiments of the present invention and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] In related technologies, the monitoring method involves technicians periodically collecting data on the number of mosquitoes attracted and the number of eggs caught in deployed oviducts based on detailed location information, and replacing expired oviducts. However, this method is inefficient because it cannot detect expired oviducts in a timely manner. Furthermore, the high cost and time required to obtain monitoring data further reduce monitoring efficiency. Moreover, the inability to determine the exact time of failure of an oviduct means that monitoring data collected before its failure cannot be effectively utilized.

[0020] Dengue fever is a global public health priority infectious disease transmitted by Aedes mosquitoes. Monitoring Aedes mosquitoes using ovitraps allows for the construction of relatively mature preventative risk rating and emergency assessment systems based on the acquired monitoring data. However, this monitoring method relies on experienced technicians operating the devices at the deployment sites and replacing ineffective ovitraps, resulting in low monitoring efficiency. The time required to acquire monitoring data is also long and inefficient, and the accuracy and real-time nature of the data are poor, leading to insufficient timeliness and sensitivity, ultimately resulting in low efficiency in monitoring Aedes mosquitoes.

[0021] In this embodiment, an intelligent monitoring circuit board is deployed within the mosquito oviduct to monitor its operational status. The monitoring data is transmitted via an Internet of Things (IoT) device embedded in the circuit board, enabling real-time, dynamic, and remote detection of dengue mosquito monitoring data within the region. This allows for timely replacement of the oviduct if its operational status malfunctions. By establishing a monitoring system based on data from oviducts with early warning capabilities, a daily routine risk monitoring system for dengue vectors can be built nationwide or even globally. By linking this system with dengue epidemiological data, a nationwide or even global dengue outbreak risk monitoring system can be established, providing a solution for dengue monitoring at the national and global levels.

[0022] This invention provides a mosquito oviduct with an early warning function, which is described below through embodiments.

[0023] Figure 1 A schematic diagram of a mosquito oviduct with an early warning function provided in an embodiment of the present invention is shown. Figure 1 As shown, the mosquito egg attractor with early warning function includes: a box top cover 11, a monitoring circuit board 12 and a trap body 13. The box top cover 11 has an internal thread on its inner side wall and an external thread on its upper outer side wall. The box top cover 11 is fixed to the upper part of the trap body 13 through the internal and external threads. On the top cover 11 facing the trap body 13, there are one or more mosquito-attracting tubes extending into the trap body 13; inside the bottom of the trap body 13, there is a first protrusion extending upward for Aedes mosquitoes to lay eggs or rest, and a second protrusion containing an attractant for Aedes mosquitoes. The second protrusion is located above the first protrusion. The second protrusion and the first protrusion are offset from each other or partially overlap in projection. Below the external thread of the trap body 13, there is a third protrusion protruding towards the center of the trap body 13. The monitoring circuit board 12 is provided with a cylindrical hole corresponding to the mosquito-attracting tube opened on the top cover 11 of the box. The mosquito-attracting tube passes through the cylindrical hole, and the monitoring circuit board 12 is fixed on the third protrusion. The monitoring circuit board 12 includes an ultrasonic water level detection module, a 3D attitude detection module, a microprocessor, a geolocation module, and a 4G communication module. An ultrasonic water level detection module is set on the monitoring circuit board 12 at the position corresponding to the water surface. It emits ultrasonic waves according to the water level monitoring cycle preset by the microprocessor, acquires the ultrasonic waves reflected back from the water surface, encapsulates the emitted ultrasonic wave information and the received ultrasonic wave information in the first water level monitoring information, and sends it to the microprocessor. The microprocessor is used to process the received first water level monitoring information and the preset water level threshold. If the water level determined by the received first water level monitoring information exceeds the upper water level threshold, it sends a geographical location acquisition command to the geographical location module and sends water level exceeding upper limit information to the 4G communication module. The 3D posture detection module is used to detect the placement status information of the mosquito and egg attractant according to the posture detection cycle preset by the microprocessor, and send the placement status information to the microprocessor. The microprocessor is also used to determine whether the mosquito trap or ovipositor has been overturned based on the received placement status information. If it is determined that it has not been overturned, no action is taken. If it is determined that it has been overturned, a location acquisition command is sent to the geolocation module and an abnormal placement information of the mosquito trap or ovipositor is output to the 4G communication module. The geolocation module obtains the location information of the mosquito and egg attractor based on the received geolocation acquisition command, and sends the location information to the 4G communication module; The 4G communication module sends the received location information and water level exceeding the upper limit information to a pre-set server, or sends the received location information and trap placement abnormality information to a pre-set server.

[0024] In this embodiment, the area where the mosquito trap is set is generally a rainy area. Frequent rainfall will flow into the trap body along with the mosquito-attracting tube, causing the water level inside the trap body to exceed the first protrusion, affecting mosquito egg-laying. Therefore, in this embodiment, an ultrasonic water level detection module monitors the distance from the water surface inside the trap body. When the water level inside the trap body exceeds a preset warning level (water level threshold), an alarm is triggered to promptly address the mosquito-attracting and egg-laying device. As an optional embodiment, the mosquito attractant is simply a mosquito-attracting channel.

[0025] In this embodiment, as an optional embodiment, Near the bottom of the side wall of the trap body, there is a water pumping hole that connects to the water surface inside the trap body. On the outer side wall of the water pumping hole, there is a water pumping switch and a switch controller. After determining that the water level exceeds the upper threshold based on the received first water level monitoring information, the microprocessor is also used to output a pumping command to the switch controller so that the switch controller can open the pumping switch to drain water.

[0026] In this embodiment, as an optional implementation, after the microprocessor outputs a pumping command to the switch controller, it can pause sending the geolocation acquisition command to the geolocation module. Alternatively, it can simultaneously send the geolocation acquisition command to the geolocation module. As another optional implementation, if the switch controller fails to control the pumping switch, the microprocessor sends a pumping switch malfunction information to the 4G communication module.

[0027] In this embodiment, after the switch controller turns on the water pump to drain the water, it is necessary to maintain a certain water level in the mosquito and egg attractor. Therefore, as another optional embodiment, The ultrasonic water level detection module is also used to emit ultrasonic waves according to a preset water level monitoring cycle, and then emit ultrasonic waves according to a preset water level monitoring sub-cycle to obtain the ultrasonic waves reflected back from the water surface. The emitted ultrasonic wave information and the received ultrasonic wave information are encapsulated in the second water level monitoring information and sent to the microprocessor. The microprocessor is also used to process the received second water level monitoring information and the preset lower water level threshold. If the water level determined by the received second water level monitoring information is lower than the lower water level threshold, it sends a sub-cycle termination command to the ultrasonic water level detection module to stop the ultrasonic water level detection module from emitting ultrasonic waves according to the preset water level monitoring sub-cycle. It also outputs a water stop command to the switch controller to close the pumping switch and seal the pumping hole.

[0028] In this embodiment, the water level monitoring cycle includes multiple water level monitoring sub-cycles. As an optional embodiment, the ultrasonic water level detection module is used to detect the water level inside the mosquito oviduct to prevent the mosquito oviduct from being in a malfunctioning state. It includes: a microelectromechanical system (MEMS) ultrasonic transmitter, a receiving element, and a driving circuit, wherein the driving circuit is used to provide power to the microelectromechanical system ultrasonic transmitter and receiving element. A microelectromechanical system ultrasonic transmitter is used to emit ultrasonic waves according to a pre-set water level monitoring sub-cycle. The receiving element is used to receive the echo information of the ultrasonic wave emitted by the ultrasonic transmitter of the microelectromechanical system, encapsulate the emitted ultrasonic wave information and the echo information to obtain the second water level monitoring information, and send it to the microprocessor.

[0029] In this embodiment, the trap is placed in the wild, and may be overturned due to some interference factors. Therefore, a 3D posture detection module is used to detect the placement status so that it can be dealt with in a timely manner when abnormal placement status information is detected.

[0030] In this embodiment, as an optional embodiment, the 3D attitude detection module includes a 3D accelerometer for detecting the placement status information that characterizes the three-dimensional coordinate information of the mosquito ovipositor. The microprocessor processes the placement status information to determine whether the mosquito ovipositor is in an upright state, so as to avoid the mosquito ovipositor tipping over and becoming in a malfunctioning state.

[0031] In this embodiment, the geolocation module is installed on the monitoring circuit board. When the mosquito attractant and oviductor is malfunctioning, the module acquires the location information of the mosquito attractant and oviductor and sends it to the 4G communication module via the microprocessor.

[0032] In this embodiment, activating the geolocation module when the mosquito ovipositor malfunctions effectively saves energy. The ultrasonic water level detection module monitors the water level inside the trap in real time, triggering an alarm when the water level rises to an abnormal position for timely intervention. This prevents the traps from becoming unusable due to excessive water volume caused by heavy rains, which could limit space within the trap and lead to its failure. This improves monitoring efficiency. Furthermore, a water intake hole connected to the water level inside the trap is located near the bottom of the side wall. A water intake switch and controller are installed on the outer wall of the hole, enabling automatic handling of abnormal water level conditions without requiring on-site intervention from technicians based on recorded location information. This further reduces the cost of monitoring Aedes mosquitoes and improves monitoring efficiency.

[0033] In this embodiment, as an optional embodiment, the monitoring circuit board further includes a mosquito entry detection module, wherein the microprocessor is also used to output a detection command to the mosquito entry detection module according to a preset infrared detection cycle, obtain the first number of mosquitoes entering the mosquito trap based on the received light intensity information and the transmitted light intensity information, and send the obtained first number of mosquitoes to the 4G communication module. When a mosquito enters the detection module, which is positioned directly opposite the mosquito trap on the monitoring circuit board, it receives a detection command and then acquires the received infrared light intensity information and the emitted infrared light intensity information through infrared transmission and reception. The received light intensity information and the emitted light intensity information are then sent to the microprocessor. The 4G communication module will also send the first mosquito count information and the current timestamp information received from the microprocessor to a pre-set server.

[0034] In this embodiment, when the mosquito entry detection module detects a signal of mosquito entry, it reports the time and number of mosquitoes entering to the backend server. The mosquito entry detection module monitors mosquito information according to a pre-set infrared detection cycle, thereby obtaining effective mosquito information (monitoring data) before the mosquito attractant and ovipositor malfunctions, thus effectively improving monitoring efficiency.

[0035] In this embodiment, as an optional implementation, an infrared detection cycle is set based on the mosquito's living and movement habits in narrow channels and the space of the mosquito-attracting tube where infrared light emission is cut off. For example, after installing and debugging a mosquito attractor with an early warning function, the mosquito enters the detection module and emits an infrared grating. Based on the mosquito's living and movement habits in narrow channels, the crossing time required for the mosquito to pass through the corresponding infrared grating is estimated, and the infrared detection cycle is set to be equal to this crossing time. As another optional implementation, considering the need for low power consumption of the device, the infrared detection cycle can also be set to be equal to the sum of the crossing time and a preset time threshold. The mosquito entering the detection module is periodically triggered by the microprocessor according to the infrared detection cycle.

[0036] In this embodiment, as an optional embodiment, the monitoring circuit board is fixed to the third protrusion by means of soldering, gluing, etc.

[0037] In this embodiment, by deploying an intelligent monitoring circuit board in a mosquito oolizer with an early warning function, the number of mosquitoes entering the oolizer is acquired. The monitoring data containing the mosquito count information is transmitted to the server using a 4G communication module (Internet of Things). This eliminates the need for experienced technicians to periodically visit the location where the mosquito oolizer is deployed to acquire monitoring data, reducing the cost of acquiring monitoring data and improving the efficiency of data acquisition. At the same time, after acquiring the mosquito count information, it is transmitted to the server in real time with timestamp information, improving the accuracy and real-time nature of the monitoring data, and enabling real-time dynamic monitoring of dengue mosquito vector density in the area.

[0038] In this embodiment, as an optional embodiment, the top cover of the box is cylindrical and made of a light-blocking material, such as black plastic that has a good attraction and retention effect on Aedes mosquitoes, while the body of the trap is made of a transparent material, such as colorless plastic that is conducive to mosquito egg-laying.

[0039] In this embodiment, as an optional embodiment, the diameter of the box top cover is 75mm, and the diameter of the trap body is 70mm. Three mosquito-attracting channels are provided on the box top cover, forming a funnel shape that is wider at the top and narrower at the bottom. As an optional embodiment, the top diameter of the mosquito-attracting channel is 12mm, the bottom diameter is 7mm, and the height is 21mm. The radius of the first protrusion is 20mm, and filter paper of a similar color to the first protrusion can be attached to it for Aedes mosquitoes to lay eggs.

[0040] In this embodiment, the attractant includes, but is not limited to, glucose water. The trap body is filled with water below the height of the first protrusion to provide a humid environment. As an optional embodiment, filter paper is wrapped around the top of the first protrusion and extends from the top to the bottom to contact the water, keeping the filter paper moist. The box top cover is made of black plastic, which can create a relatively cool environment inside the trap body. Aedes mosquitoes enter the trap body through the mosquito-attracting inlet on the box top cover. The filter paper attached to the first protrusion at the bottom of the bottle is partially soaked with water, forming a moist and rough surface, creating an environment suitable for mosquitoes to lay eggs.

[0041] In this embodiment, the mosquito-attracting tube is wider at the top and narrower at the bottom, extending into the body of the trap. This facilitates the entry of mosquitoes into the trap while effectively preventing them from flying out. It can be applied to scenarios where mosquitoes are attracted to lay eggs or adult Aedes mosquitoes are captured for dengue virus detection.

[0042] In this embodiment, a circuit board with intelligent monitoring is installed inside the mosquito trap body of the mosquito and egg attractor with early warning function. Specifically, the circuit board is placed on the third protrusion on the trap body. This is an optional embodiment. Figure 2 A schematic diagram of the monitoring circuit board structure provided in an embodiment of the present invention is shown. Figure 2 As shown, corresponding to the case where there are three mosquito attractors, for example, three hexagonal mosquito attractors (with hexagonal inlets), the monitoring circuit board has three hexagonal through holes (tube holes), namely the first hexagonal through hole 201, the second hexagonal through hole 202, and the third hexagonal through hole 203. The three hexagonal mosquito attractors pass through their respective three hexagonal through holes. As an optional embodiment, the tube holes are wider at the top and narrower at the bottom, matching the mosquito attractors.

[0043] In this embodiment, as an optional embodiment, the microprocessor includes an infrared detection timer and a detector, and the mosquito entry detection module includes an infrared transmitter and an infrared receiver, wherein... An infrared detection timer, set in the monitoring circuit board, is used to wake up the device according to the infrared detection cycle preset on the monitoring circuit board and output a detection command to the infrared transmitter. An infrared transmitter is installed on the inner wall of the monitoring circuit board on the side that is in contact with the mosquito attractor. It receives the detection command output by the infrared detection timer and emits infrared light towards the mosquito attractor. An infrared receiver is installed on the inner wall of the monitoring circuit board opposite to the infrared transmitter. It receives the light intensity information of the infrared light emitted by the infrared transmitter and outputs the light intensity information to the detector. The detector, based on the received light intensity information and the light intensity information of the infrared light emitted by the infrared transmitter, obtains information on the number of mosquitoes entering the mosquito trap or whether mosquitoes have entered the mosquito trap and the time of entry, and sends the obtained mosquito count information to the 4G communication module.

[0044] In this embodiment, an infrared transmitter and an infrared receiver form an infrared transmitting / receiving array 204. As an optional embodiment, the infrared transmitter and receiver in the infrared transmitting / receiving array can be configured as one or more corresponding units. The infrared transmitting / receiving array forms an infrared grating through infrared light transmission, wherein the infrared transmitter is the infrared light emitting end of the infrared grating, and the receiving array (one or more infrared receivers) is the infrared light receiving end of the infrared grating. When no mosquitoes fly in, the intensity of the infrared light received by the receiving array is similar to the intensity of the emitted infrared light. When mosquitoes fly in, they block the infrared light emitted by the infrared light emitting end, causing the intensity of the infrared light received by the receiving array to be significantly weaker than the emitted infrared light intensity. Therefore, based on the intensity of the emitted infrared light and the intensity of the received infrared light, it can be determined whether mosquitoes have entered. Furthermore, if multiple mosquitoes fly in, the blocked area is larger, resulting in a greater light intensity difference. Therefore, the number of mosquitoes that flew in can also be determined based on the intensity difference between the received light intensity information and the intensity information of the infrared light emitted by the infrared transmitter. As another optional embodiment, since mosquitoes enter and their obstruction provides volume information, the volume of the obstructed area can be determined based on the light intensity difference. This volume can be compared with a pre-set mosquito volume threshold to determine the number of mosquitoes that have entered. Alternatively, the signal from the infrared receiver when the infrared emitting element is not emitting infrared light can be used as background data, and the signal from the infrared receiver when the infrared emitting element is emitting infrared light can be used as detection data. The difference between these two data points serves as reference data for subsequent detection, thus eliminating environmental influences. When mosquitoes enter, they disturb the infrared light emitted by the infrared emitting element. This disturbance includes the mosquitoes obstructing and reflecting the infrared light, causing a change in the signal intensity received by the infrared receiver. This change is then compared with the aforementioned reference data to determine whether mosquitoes have entered.

[0045] In this embodiment, in order to improve the detection accuracy of mosquito count, as an optional embodiment, the monitoring circuit board further includes: a first image module, which is set at the position of the monitoring circuit board facing the mosquito trap, and after receiving the detection command sent by the microprocessor, takes an image of the mosquito trap and sends the captured image information to the microprocessor. The microprocessor is also used to identify the second mosquito count information contained in the image information based on the received image information and a pre-built mosquito identification model. If the error between the second mosquito count information and the first mosquito count information is within a preset error range, no processing is performed. If the error between the second mosquito count information and the first mosquito count information exceeds the preset error range, the image information is sent to the 4G communication module. The 4G communication module is also used to send the received image information to a pre-set server.

[0046] In this embodiment, the first image module and the mosquito entry detection module can be located at different positions in the vertical direction of the mosquito attractor, or at different positions in the same horizontal direction of the mosquito attractor. The server includes, but is not limited to, a user terminal and a backend server. The first image module includes, but is not limited to, a digital camera. As an optional embodiment, the digital camera includes: an image sensor and a flash LED, wherein the flash LED is turned on after receiving a detection command sent by the microprocessor, and the image sensor captures image information based on the flash LED, and sends the captured image information to the microprocessor. As an optional embodiment, the image information can be multiple frames of images captured according to a set shooting cycle; as another optional embodiment, the image information can also be captured video.

[0047] In this embodiment, the first image module is used to acquire high-definition images of the mosquito egg attractor with early warning function and transmit them to the microprocessor. The microprocessor then identifies mosquitoes and counts them based on a pre-built mosquito identification model and compares the results with the mosquito count identified based on light intensity information to improve the accuracy of mosquito count identification. If the two are inconsistent, the image information is sent to the backend server so that the backend server can perform manual analysis based on the image information to correct the received first mosquito count information.

[0048] In this embodiment, the oviposition of mosquitoes can also be monitored. Therefore, as another optional embodiment, the monitoring circuit board further includes: The second image module is set on the monitoring circuit board at the position corresponding to the first protrusion. It takes pictures of the spawning according to the preset spawning monitoring cycle and sends the captured spawning image information to the 4G communication module through the microprocessor.

[0049] In this embodiment, a 4G communication module is used to send oviposition image information to a backend server. This allows the backend server to process the oviposition image information sent by each trap according to a pre-set mosquito egg identification strategy, determining whether there are mosquito eggs and the number of eggs in the mosquito trap with early warning function.
