[0026] The present disclosure will now be described through several specific embodiments. To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and components are omitted. When any component of an embodiment of the present disclosure appears in more than one drawing, the component is indicated by the same or similar reference numerals in each drawing.
[0027] Mosquitoes are vectors for many human and animal diseases, and the pathogens they carry can cause major public health problems such as malaria and dengue fever. Different mosquito species play significantly different roles in disease transmission, and accurate identification of mosquito species is a prerequisite for assessing transmission risks, delineating epidemic areas, and implementing precise prevention and control measures.
[0028] By using light as a passive attractant, various insects are sensitive to light to some extent. Therefore, when attracting mosquitoes, other insects such as moths and beetles are also introduced. This makes it difficult to accurately identify the target mosquitoes because the insects caught are diverse.
[0029] When identifying mosquitoes, optical grating blocking counting or infrared counting sensors can be used to count the number of mosquitoes flying through the beam. However, the same mosquito may repeatedly fly into and out of the beam within the enclosure, resulting in multiple counts. Alternatively, if multiple mosquitoes pass through the beam simultaneously, only one signal is generated, leading to missed counts and inaccurate mosquito identification. Furthermore, this counting method cannot distinguish the species of mosquitoes passing through.
[0030] For identifying target mosquito species, optical sensors can be used to capture their wingbeat characteristics for identification. A "wingbeat" refers to the action of an insect or flapping-winged aircraft flapping its wings up and down in flight; its frequency, amplitude, and waveform are collectively referred to as the "wingbeat characteristic." Different mosquito species exhibit different wingbeat frequency ranges and harmonic components (i.e., wingbeat characteristics) when hovering or flying forward. While this method can identify target mosquitoes in environments with a variety of insects, it is susceptible to the effects of airflow disturbances, mosquito flight angles, and speeds. These factors can cause the wingbeat signal corresponding to the wingbeat characteristic to be submerged or distorted by environmental noise, thus failing to accurately identify the target mosquito species.
[0031] When identifying the species of a target mosquito, images can be captured, and microscopic features such as body length, wing markings, beak shape, and leg color can be analyzed using image recognition algorithms to identify the species. These image recognition algorithms rely on obtaining complete and clear structural information about the target mosquito. Therefore, to obtain a clear image, the mosquito needs to remain relatively still when taking the picture.
[0032] For example, a method can be used to stun mosquitoes with a momentary high voltage from the power grid, causing them to lose some of their mobility and fall into the shooting area for photographing. However, this method is unreliable because high-voltage discharge can cause mosquitoes to break their wings or legs or burst their abdomens after being electrocuted, physically destroying key classification characteristics and leading to inaccurate mosquito species identification. Alternatively, if the electric shock is insufficient, the mosquito may continue to move and cannot be fixed in place, resulting in unclear images.
[0033] For example, sticky paper can be used to fix target mosquitoes. However, because the shape of the target mosquitoes when they hit and stick to the adhesive surface of the sticky paper is not fixed, it cannot fully reveal the microscopic features used to identify the species; or, multiple mosquitoes may stick to the same spot on the sticky paper at the same time, making it difficult to accurately identify the species of the target mosquitoes by fixing them with sticky paper.
[0034] For example, mosquitoes can be immobilized by their bites for photographing. Alternatively, an amnion can be suspended within a space where a mosquito is being captured, attracting it with the scent of the biological tissue. However, this is cumbersome, requiring the amnion to be kept moist and replenished regularly. Furthermore, even with a camera that can be turned around at any time—for example, when a mosquito is on the amnion—the timing and direction of the mosquito's movement can still cause problems with the photographing process. For instance, the mosquito might briefly stop and then fly away immediately, leaving it outside the photographing range.
[0035] Therefore, taking clear pictures of the target mosquitoes is key to using identification algorithms to identify the species of the target mosquitoes.
[0036] At least one embodiment of this disclosure provides a camera device for detecting mosquitoes. The camera device includes a mosquito attracting device, a mosquito storage channel, a camera plate, a camera module, and a pressure control device. The mosquito attracting device is configured to provide at least one attractant. The mosquito storage channel includes a first end and a second end, wherein the first end is provided with an insect inlet component, and at least one attractant in the mosquito attracting device is configured to be released through an inlet of the insect inlet component to attract corresponding mosquitoes in the external environment to gather around the inlet. The camera plate is disposed at the second end and includes a shooting surface for photographing mosquitoes. The camera module is disposed opposite to the shooting surface. The pressure control device is disposed at the second end, wherein the pressure control device is configured to provide a negative pressure on the air inlet side facing the camera plate. The camera plate includes a plurality of through holes smaller than the body length of the target mosquito, and the camera module is further configured to photograph the target mosquito after the target mosquito in the mosquito storage channel is adsorbed onto the shooting surface in response to the pressure control device. The target mosquito is a mosquito that is sucked into the mosquito storage channel by the negative pressure.
[0037] In the above-described embodiments of the imaging device for mosquitoes disclosed herein, by providing multiple through holes smaller than the body length of the target mosquito on the imaging plate, and configuring the air pressure control device to provide negative pressure with the air intake side facing the imaging plate, the target mosquito can be controllably fixed on the imaging plate in its complete form (without any body defects or obstructions); and by filtering out miscellaneous insects smaller than the target mosquito through the multiple through holes on the imaging plate, the captured content is clearer, thereby enabling accurate identification of the type and number of the target mosquito.
[0038] The various embodiments of this disclosure will now be described with reference to specific examples.
[0039] Figure 1 A schematic diagram of the internal partial structure of a camera device for detecting mosquitoes, provided in at least one embodiment of the present disclosure, is shown. Figure 2 for Figure 1 A partial explosion diagram of the camera device.
[0040] like Figure 1 and Figure 2 As shown, the camera device 1000 for detecting mosquitoes includes a mosquito attracting device 10, an insect storage channel 20, an insect inlet assembly 30, a camera tablet 40, a camera module 50, an air pressure control device 60, and a collector 70.
[0041] The mosquito attracting device 10 is configured to provide at least one attraction source. For example, the mosquito attracting device 10 can provide at least one of a gas attraction source, a light attraction source, and an attractant source.
[0042] For example, the mosquito attracting device 10 is configured to provide multiple attraction sources simultaneously, such as gas attraction sources and light attraction sources, to cover different attraction distances. For example, the mosquito attracting device 10 includes a carbon dioxide release port 101 to provide a carbon dioxide gas attraction source. For example, the mosquito attracting device 10 includes an attractant box 103 to provide an attractant attraction source by placing attractant in the attractant box. For example, the opening of the attractant box 103 is provided with an attractant box cover 1031, and the attractant box cover 1031 is provided with multiple through holes so that the attractant in the attractant box 103 can be released but not lost.
[0043] The insect storage channel 20 includes a first end and a second end, wherein the first end is provided with an insect inlet component 30, and at least one of the attractants in the mosquito attracting device 10 is configured to be released through the insect inlet 301 of the insect inlet component 30 to attract corresponding mosquitoes in the external environment to gather around the insect inlet 301.
[0044] For example, the insect inlet assembly 30 can be installed at the first end of the insect storage channel 20 by means of threaded connection or locking connection, or the insect inlet assembly 30 can also be welded to the first end of the insect storage channel 20. This disclosure does not limit this.
[0045] For example, a carbon dioxide gas release port 101 is provided on the inner wall of the insect storage channel 20 so that the supplied carbon dioxide gas is released into the external environment through the insect inlet 301. For example, the opening of the attractant box 103 is configured to face the insect storage channel 20 so that the attractant in the attractant box 103 can be released into the external environment through the insect inlet 301.
[0046] In this way, by releasing at least one attractant (carbon dioxide gas and / or attractant) through the insect inlet 301, the corresponding mosquitoes in the external environment can gather around the insect inlet 301, which is beneficial for capturing mosquitoes.
[0047] A camera tablet 40 is disposed at the second end of the insect storage channel 20 and includes a shooting surface for capturing mosquitoes. A camera module 50 is disposed opposite the shooting surface. For example, the camera module 50 includes a camera 501 for capturing images, and may also include a supplementary light 502 to provide supplementary light when needed. The camera module 50 is configured to capture and output captured content; for example, the captured content output by the camera module 50 may be an image or video, and this disclosure is not limited thereto. For example, the camera module 50 may also include a memory to store images or videos captured by the camera. For example, the camera may be a CMOS camera; embodiments of this disclosure do not limit the type or specifications of the camera.
[0048] The first end and the second end of the insect storage channel 20 are different ends. For example, the first end and the second end are the two ends of the channel of the insect storage channel 20, or at least one of the first end and the second end can be an opening end provided on the side wall of the insect storage channel 20.
[0049] For example, the insect storage channel 20 can be an L-shaped bend, with the first and second ends forming the two ends of the channel. To facilitate shooting by the camera module 50, an opening can be provided in the channel wall as a third end, allowing the camera 501 and the supplementary light 502 to capture images of the camera tablet 40 through the insect storage channel 20. Alternatively, an opening can be provided at the bend of the L-shaped insect storage channel 20 as a third end to mount the camera module 50. This eliminates the need for the camera module 50 to occupy space within the insect storage channel 20, thus avoiding any restriction on mosquito activity within the channel.
[0050] A pressure control device 60 is disposed at the second end, wherein the air intake side of the pressure control device 60 providing negative pressure is disposed facing the camera plate 40, and the pressure control device 60 is configured to provide negative pressure to the camera plate 40. Here, negative pressure is the air pressure that draws air from the external environment into the insect storage channel 20, and positive pressure is the air pressure that blows air out of the insect storage channel 20.
[0051] For example, the air pressure control device 60 may include a device that can provide negative pressure, such as a fan or exhaust fan, or a device that can provide positive pressure, such as a fan or gas cylinder. The embodiments disclosed herein do not limit this.
[0052] For example, the camera plate 40 includes multiple through holes smaller than the body length of the target mosquito, and the camera module 50 is further configured to photograph the target mosquito after the air pressure control device 60 adsorbs the target mosquito in the insect storage channel 20 onto the shooting surface; wherein, the target mosquito is a mosquito sucked into the insect storage channel 20 by negative pressure. For example, the target mosquito is a live mosquito that can fly within the insect storage channel 20.
[0053] Since the air pressure control device 60 is located at the second end, and the imaging plate 40 includes multiple through holes, the air pressure control device 60 can provide negative pressure to the insect inlet 301 through the multiple through holes, allowing the mosquitoes gathered around the insect inlet 301 to be sucked into the insect storage channel 20. It can also cause the target mosquitoes to adhere to the imaging surface of the imaging plate 40, thus ensuring that the target mosquitoes are fixed on the imaging plate in a complete form (without any body defects or obstructions). Furthermore, the method provided in the above embodiment allows for controllable fixation of the target mosquitoes; by controlling the switch of the air pressure control device 60, it can be ensured that the target mosquitoes are fixed on the imaging plate at the moment of taking the picture. This results in clear images captured by the camera module, which is beneficial for identifying the species of target mosquitoes.
[0054] For example, the camera device 1000 also includes a controller 100. In order to make the target mosquitoes evenly adsorbed on the shooting surface of the camera plate 40, the controller 100 can control the air volume value when the air pressure control device 60 is started, so as to make the target mosquitoes evenly adsorbed on the shooting surface. The air volume value ranges from 1.9 to 2.3 cubic meters per minute.
[0055] By evenly adsorbing the mosquitoes, the number of mosquitoes determined from the photographed content is accurate.
[0056] The camera device 1000 also includes a controller 100, which is used to operate and control the various devices within the camera device 1000. For example, the controller 100 may include a central processing unit, a microprogrammable controller (MCU), or a programmable logic controller (PLC), such as a single-chip microcomputer, and implements control functions by executing a pre-written control program.
[0057] For example, controller 100 is configured to control at least one decoy to release according to a selected first rhythm.
[0058] For example, controller 100 can control carbon dioxide release port 101 to release according to rhythm A selected for carbon dioxide gas release, and can control the device of photo-attracting source to release according to rhythm B selected for it, where rhythm A and rhythm B are different; for example, multiple attracting sources can be selected to release according to the same rhythm, and this disclosure does not limit this.
[0059] Taking carbon dioxide gas release as an example, if a preset first rhythm is selected for carbon dioxide gas, the controller 100 is also configured to release carbon dioxide gas according to the following preset first rhythm in response to environmental monitoring parameters meeting preset conditions:
[0060] During a first preset time period, carbon dioxide gas is controlled to be released through the insect inlet 301; in response to the end of the first preset time period, the release of carbon dioxide gas is controlled to stop, and the system waits during a second preset time period; in response to the end of the second preset time period, the gas pressure control device 60 is controlled to be turned on during a third preset time period, wherein the duration of the second preset time period is longer than the duration of the first preset time period and longer than the duration of the third preset time period.
[0061] Environmental monitoring parameters include at least one of temperature, humidity, and rainfall. Corresponding temperature and humidity sensors and rainfall sensors can be installed externally on the camera device 1000. The values measured by the temperature and humidity sensors and the rainfall sensors can be transmitted to the controller 100 to determine whether the environmental monitoring parameters meet the preset conditions. Since mosquitoes are relatively sensitive to the external environment, the preset conditions can be determined based on the impact of the external environment on mosquito activity.
[0062] For example, the released carbon dioxide gas can be provided by a carbon dioxide tank configured with the camera device 1000. By releasing carbon dioxide gas when environmental monitoring parameters meet preset conditions, and by releasing it in a manner that follows a preset first rhythm, the limited resources in the carbon dioxide tank can be effectively utilized, and the consumption rate and replacement frequency of the carbon dioxide tank are greatly reduced, thereby reducing the maintenance costs associated with frequent ventilation.
[0063] For example, since mosquitoes' activity decreases when the temperature is below 18 degrees Celsius and above 40 degrees Celsius, a preset condition can be set for a temperature greater than or equal to 18 degrees Celsius and less than or equal to 40 degrees Celsius, so that the release of carbon dioxide gas can be activated when this preset condition is met.
[0064] For example, by measuring rainfall, it can be determined whether it is raining in the outside environment. If it is raining, mosquitoes will not be sucked into the camera equipment, and the release of carbon dioxide can be turned off to save carbon dioxide.
[0065] For example, the preset conditions may include the temperature and rainfall conditions mentioned above. The release of carbon dioxide gas can be initiated when all or some of the preset conditions are met. The specific conditions and triggering methods in the embodiments of this disclosure are not limited.
[0066] By setting preset conditions, the camera device can be prevented from releasing carbon dioxide gas when there are no mosquitoes, thus avoiding excessive consumption of the attractant.
[0067] After the preset conditions are met, the preset first rhythm is executed. The preset first rhythm includes a first preset period for releasing carbon dioxide gas, a second preset period for stopping the release and waiting, and a third preset period for activating the gas pressure control device 60.
[0068] When carbon dioxide gas is released during the first preset time period, the molar mass of carbon dioxide gas (CO2) is approximately 44 g mol under the same temperature and pressure. -1 It is much larger than the average molar mass of air (≈29 g mol) -1 This means that carbon dioxide gas is heavier than air, and there is a density difference between the two. Therefore, under the influence of gravity, carbon dioxide gas will sink.
[0069] After that, the release of carbon dioxide stops and the second preset period of waiting begins. Some of the CO2 sinks and diffuses along the ground to the bottom layer. It is then carried back to the insect inlet 301 by molecular diffusion and convection caused by temperature difference, causing the carbon dioxide gas to accumulate again and gradually increase in concentration.
[0070] Then, the air pressure control device 60 is turned on, which can draw carbon dioxide gas into the insect inlet 301 through the provided negative pressure, thereby agitating the released carbon dioxide gas and forming a carbon dioxide attracting gas cloud around the insect inlet 301.
[0071] For example, the insect inlet 301 can be used with the inlet facing the ground, that is, carbon dioxide gas is released towards the ground, thereby helping to generate carbon dioxide attractant gas masses.
[0072] By releasing carbon dioxide gas according to the preset first rhythm, a carbon dioxide attracting gas cloud can be formed around the insect inlet, thereby more effectively attracting mosquitoes to gather around the insect inlet.
[0073] In some embodiments of this disclosure, a first sensor for monitoring carbon dioxide gas content may be provided at the insect inlet 301, and the controller 100 is further configured to release carbon dioxide in response to the detected carbon dioxide gas content being less than or equal to a content threshold during a first preset time period; and to stop releasing carbon dioxide in response to the detected carbon dioxide gas content being greater than the content threshold.
[0074] For example, the carbon dioxide gas content is expressed as a volume fraction, and the content threshold ranges from 1000 to 2000 ppm. For example, the content threshold can be set to 1100 ppm, 1200 ppm, 1300 ppm, 1400 ppm, 1500 ppm, 1600 ppm, 1700 ppm, 1800 ppm, or 1900 ppm, etc.
[0075] Carbon dioxide content is the percentage of carbon dioxide molecules in the total number of gas molecules (µmol / mol). -1 (Volume ratio). ppm is a dimensionless unit of proportion, representing parts per million. In gas concentration, 1 ppm = 1 µmol mol. -1 That is, there is one carbon dioxide gas molecule in every million gas molecules.
[0076] By monitoring the carbon dioxide gas content near the insect inlet, the release concentration of carbon dioxide gas in the first preset time period can be more accurately determined, thereby achieving the optimal concentration range for attracting mosquitoes.
[0077] In some embodiments of this disclosure, the duration of the first preset time period in the preset first rhythm ranges from 10 to 300 seconds, the duration of the second preset time period ranges from 37 to 1020 seconds, and the duration of the third preset time period ranges from 10 to 300 seconds.
[0078] For example, the duration of the first preset time period can be set to 15-25 seconds, 15-50 seconds, 15-100 seconds, 150-250 seconds, etc.; the duration of the second preset time period can be set to 37-100 seconds, 37-200 seconds, 37-300 seconds, 40-500 seconds, 550-800 seconds, 550-900 seconds, etc.; and the duration of the third preset time period can be set to 15-25 seconds, 15-50 seconds, 15-100 seconds, 150-250 seconds, etc.
[0079] The duration selection for the first, second, and third preset time periods must satisfy the condition that the second preset time period is longer than the first preset time period and also longer than the third preset time period, thereby improving the formation of carbon dioxide-induced gas masses. For example, the first preset time period can be set to 20 seconds, the second preset time period to 120 seconds, and the third preset time period to 40 seconds.
[0080] For example, during the third preset time period, while carbon dioxide gas is being drawn in through the insect inlet 301, mosquitoes gathered around the insect inlet 301 are also drawn into the insect storage channel 20.
[0081] In some embodiments of this disclosure, the controller 100 is also configured to control the camera module 50 to start shooting in response to the end of at least one preset first rhythm, and the barometric pressure control device 60 is activated during the shooting of the camera module 50.
[0082] After the third preset time period ends, the air pressure control device 60 can remain on to adhere the target mosquito to the shooting surface of the camera tablet 40, thereby making the content captured by the camera module 50 clearer.
[0083] In some embodiments of this disclosure, the camera tablet 40 can be configured as a gate of the first gate chamber assembly 41. The camera tablet 40 is displayed when the first gate chamber assembly 41 is in a closed state, and the camera tablet 40 is hidden when the first gate chamber assembly 41 is in an open state.
[0084] The gate of the first gate chamber assembly 41 can be opened or closed based on the gear-rack principle, the electromagnetic direct push principle, or the mechanical screw principle, and this disclosure does not limit this.
[0085] For example, the gate of the first gate chamber assembly 41 is the first gate 420, and the camera tablet 40 serves as the first gate 420.
[0086] Taking the mechanical screw principle as an example, the first gate chamber assembly 41 also includes a first gate track 430, a first gate chamber 410, a first limit switch 4301, a first motor 4302, and a first lead screw 4303.
[0087] When the first gate chamber assembly 41 performs opening or closing, the first motor 4302 drives the first lead screw 4303 to rotate, and the rotational motion is converted into linear motion of the first gate 420 along the first gate track 430 through the lead screw-nut pair; when the gate rises to the "fully open" or falls to the "fully closed" limit position, the corresponding first limit switch 4301 is triggered, thereby providing a feedback signal to the controller 100 to realize the safe opening and closing of the first gate 420.
[0088] In some embodiments of this disclosure, the camera device 1000 also includes a collector 70 disposed on the outlet side where the pressure control device 60 provides positive pressure.
[0089] The controller 100 is also configured to, in response to the camera module 50 finishing shooting, control the air pressure control device 60 to shut down and control the first gate chamber assembly 41 to switch to the open state; and in response to the first gate chamber assembly 41 being in the open state, control the air pressure control device 60 to start so as to collect the mosquitoes that have finished shooting into the collector 70.
[0090] For example, the air pressure control device 60 can be turned off for a period of time (i.e., the air volume value is 0), and then the first gate chamber assembly 41 can be switched from the closed state to the open state, so that the mosquitoes that are attached to the shooting surface of the camera plate 40 (first gate 420) when the camera takes pictures can resume their activity and leave the camera plate 40.
[0091] If some mosquitoes do not leave the camera tablet 40 on their own after the shooting is completed, during the process of controlling the opening of the first gate chamber component 41, these mosquitoes will be squeezed by the first gate track 430, causing their bodies to stick to the camera tablet 40, resulting in contamination and affecting the clarity of subsequent shooting content.
[0092] For example, a brush can be installed on the first gate track 430, with the brush surface facing the imaging surface of the camera tablet 40.
[0093] In this way, the brush can self-clean the camera tablet during the opening and closing of the first gate chamber assembly, avoiding contamination of the camera tablet and ensuring clear recording.
[0094] For example, the camera plate 40 can be made of a material with a smooth surface and non-reflective properties, such as acrylic.
[0095] In some embodiments of this disclosure, the plurality of through holes in the camera plate 40 are tapered through holes, and the first diameter of the tapered through hole on the shooting surface of the camera plate 40 is smaller than the second diameter on the non-shooting surface of the camera plate 40.
[0096] For example, the first diameter ranges from 0.9 to 1.5 mm, and the second diameter ranges from 1.5 to 2.5 mm.
[0097] Because the camera plate 40 has a certain thickness, and the legs of the target mosquito are relatively thin, the mosquito's legs can easily get stuck in the multiple through holes in the camera plate when it is adsorbed. Therefore, all the through holes are tapered, and the first diameter of the through hole on the shooting surface is smaller than the second diameter on the non-shooting surface. This allows the brush to easily clean the mosquito's legs stuck in the through holes during the opening and closing of the shutter, thus avoiding contamination of the camera plate.
[0098] Furthermore, since the first diameter of the shooting surface is smaller than the second diameter of the non-shooting surface, that is, the side with a larger diameter is adjacent to the air intake side of the air pressure control device 60, the negative pressure that adsorbs the target mosquito on the shooting surface is sufficient.
[0099] Figure 3 A schematic diagram of the internal partial structure of a camera device for detecting mosquitoes, provided in at least one embodiment of the present disclosure, is shown. Figure 4 for Figure 3 A partial explosion diagram of the camera device.
[0100] The camera device 1000 also includes a second gate chamber assembly 51 and a centralized camera compartment 80. The second gate chamber assembly 51 is disposed between the first gate chamber assembly 41 and the insect storage channel 20, and the centralized camera compartment 80 is disposed between the second gate chamber assembly 51 and the first gate chamber assembly 41. When the second gate chamber assembly 51 is in the closed state, the insect storage channel 20 and the centralized camera compartment 80 are spatially isolated, and when it is in the open state, the insect storage channel 20 and the centralized camera compartment 80 are spatially connected.
[0101] The opening or closing of the second gate chamber assembly 51 can be achieved based on the gear-rack principle, the electromagnetic direct push principle, or the mechanical screw principle. The implementation principle of the second gate chamber assembly 51 can be the same as or different from that of the first gate chamber assembly 41. This disclosure does not limit this.
[0102] Taking the opening or closing of the second gate chamber assembly 51 as an example, which is achieved through a mechanical screw principle, the second gate chamber assembly 51 includes a second gate chamber 510, a second gate 520, a second gate track 530, a second limit switch 5301, a second motor 5302, and a second lead screw 5303. Since the second gate chamber assembly 51 is implemented using a mechanical screw principle, it is the same as the implementation method of the first gate chamber assembly 41 described above, and will not be repeated here.
[0103] Taking the release of the gas attractant according to the preset first rhythm as an example, the shooting process of starting the shooting after each preset first rhythm is rather rigid. If the number of target mosquitoes inhaled into the insect storage channel 20 is too small or there are none after the preset first rhythm ends, the content captured cannot achieve the effect of counting the number of target mosquitoes and identifying their species. In addition, the frequent start-up of the camera module and air pressure control device will also accelerate their wear and tear.
[0104] In some embodiments of this disclosure, the controller 100 is also configured to control the second gate chamber assembly 51 to be in an open state during a third preset period of time so as to collect target mosquitoes into the centralized camera chamber 80 by means of the activated air pressure control device 60.
[0105] For example, to avoid excessive shooting frequency, a shooting interval can be set. This interval can be manually set. If the shooting interval is not reached after the third preset time period of a preset first rhythm, the second gate chamber component 51 is controlled to close, thus sealing the target mosquitoes in the centralized camera chamber 80. The preset first rhythm is then re-executed.
[0106] For example, the second gate 520 could be a gate to prevent mosquitoes collected in the centralized camera compartment 80 from escaping when the gate is closed.
[0107] For example, the controller 100 is also configured to, in response to the shooting interval not being reached and at least one preset first rhythm ending, control the second gate chamber assembly 51 to switch to the closed state, shut down the air pressure control device 60, and re-execute the preset first rhythm; or, in response to the shooting interval being reached and at least one preset first rhythm ending, control the camera module 50 to start shooting.
[0108] By setting the camera device 1000 to a dual-gate cooperative control structure, the shooting frequency can be reduced as needed through a cycle, and the collected mosquitoes are stored in a centralized shooting chamber to prevent the target mosquitoes that have been inhaled into the insect storage channel from escaping.
[0109] In order to enable the shooting interval to be dynamically adjusted according to the current environmental monitoring parameters and the number of mosquitoes inhaled, for example, the controller 100 is also configured to determine the shooting interval of the camera module 50.
[0110] For example, the shooting interval determined by the controller 100 is an integer multiple of the total duration of the preset first rhythm; the shooting interval is determined based on at least one of the current shooting interval, the number of mosquitoes currently captured by the camera module, and the current environmental monitoring parameters.
[0111] For example, the controller 100 can determine the shooting interval based on the above parameters by means of lookup tables, condition judgments, etc. This disclosure does not limit the specific method of determining the shooting interval.
[0112] The total duration of the preset first rhythm is the sum of the durations of the first preset time period, the second preset time period, and the third preset time period.
[0113] For example, if the current shooting interval is 1 times the preset total duration of the first rhythm, and the current number of mosquitoes captured is 1, then the shooting interval can be changed to 2 times the preset total duration of the first rhythm (i.e., the preset first rhythm is executed twice before shooting).
[0114] For example, if the current shooting interval is 3 times the preset total duration of the first rhythm (i.e., the preset first rhythm is executed 3 times before shooting), the number of mosquitoes currently captured is 10, the temperature in the current environmental monitoring parameters is 30 degrees Celsius (mosquito activity is normal), and the monthly rainfall is 200 mm (mosquito density is significantly increased), then the shooting interval can be changed to 1 times the preset total duration of the first rhythm.
[0115] By dynamically determining the shooting interval based on one or more factors, including the current shooting interval, the number of mosquitoes currently captured, and current environmental monitoring parameters, the number of invalid shots is reduced, thus mitigating the wear and tear on related devices.
[0116] Figure 5 A front left-axis perspective view of a camera device for detecting mosquitoes provided in at least one embodiment of the present disclosure is shown.
[0117] like Figure 5 As shown, the camera device 1000 also includes a wireless communication device 90, which may include, for example, a modem, a signal transmitting and receiving device, an antenna, etc. For example, the wireless communication device 90 may support common wireless communication protocols, such as Bluetooth, Wi-Fi (e.g., 4G or 5G network protocols), NFC, etc., and this disclosure does not limit it.
[0118] For example, after the camera module 50 has finished capturing the content, it can upload it to the network via the wireless communication device 90, and the image recognition algorithm model or video recognition algorithm model mounted in the cloud can be used to identify the type and number of mosquitoes in the captured content.
[0119] For example, the types and numbers of mosquitoes identified can be uploaded to the local area network along with current environmental monitoring parameters (temperature, humidity, rainfall, etc.) to form a local heat map and trend map that integrates meteorological and mosquito dynamics by analyzing environmental monitoring parameters and historical occurrence data in real time, thus establishing a precise local area network for mosquito early warning.
[0120] To avoid data congestion and bandwidth waste caused by frequent uploads, the controller 100 is also configured to upload the current shooting data of the camera module 50 to the network via the wireless communication device 90 in response to the number of mosquitoes currently captured by the camera module 50 meeting a preset threshold.
[0121] For example, the number of mosquitoes currently captured is identified by the local processing device.
[0122] For example, the local processing device is equipped with a local recognition algorithm model (image recognition algorithm model or video recognition algorithm model), which can identify the number of mosquitoes in the currently captured content locally.
[0123] For example, the local processing device is also configured to not upload the currently captured content if the number of mosquitoes captured is below a preset upload threshold. This is to avoid wasting bandwidth and straining storage by uploading photos without mosquitoes.
[0124] It should be noted that this disclosure does not limit the image recognition algorithm model or video recognition algorithm model mentioned above. For example, the image recognition algorithm model can be based on Visual Geometry Group Network (VGG), Vision Transformer (ViT), etc., while the video recognition algorithm model can be based on 3-Dimensional Convolutional Networks (C3D), TimeSformer (TSf), Video Swin Transformer (VST), etc.
[0125] The camera device 1000 also includes a display device 92, wherein the display device 92 is used to display the operating status of the camera device, and / or may further have a touch function, thereby providing a control panel for the camera device.
[0126] The camera device 1000 also includes a handle 93, a mounting component 94, and a maintenance door 95. The handle 93 facilitates the movement of the camera device 1000, the mounting component 94 facilitates the fixation of the camera device 1000, and the maintenance door 95 facilitates the maintenance of the camera device 1000.
[0127] The mosquito attracting device 10 of the camera device 1000 also includes a UV lamp 102 to provide a light attractant. For example, the UV lamp 102 can also be controlled to switch on and off by releasing another rhythm selected for the UV lamp 102 (such as the B rhythm mentioned above). For example, when the environmental monitoring parameters meet preset conditions, the controller controls the light attractant (UV lamp 102) to be turned on for a period of time before the preset first rhythm, and turns off the light attractant in response to the start of the preset first rhythm.
[0128] Because the light attractor has a wide attraction range and attracts many other insects, it first lures mosquitoes and other insects from a distance together. Then, the light attractor is turned off, and the mosquitoes are attracted by releasing carbon dioxide gas through a preset first rhythm. Since other insects are not attracted to the released carbon dioxide gas, they will not gather at the entrance. In addition, there are many types of mosquitoes. If you want to enhance the attraction effect on a specific type of mosquito, you can place the corresponding attractant in the attractant box 103.
[0129] For example, since Aedes mosquitoes are the main vector for dengue fever, baits targeting Aedes mosquitoes can be placed to enhance their attraction.
[0130] Figure 6 A front view of the appearance of a camera device for detecting mosquitoes provided in at least one embodiment of the present disclosure is shown. Figure 7 The image shown is a right view of the appearance of a camera device for detecting mosquitoes provided in at least one embodiment of the present disclosure. Figure 8 A top view of the appearance of a camera device for detecting mosquitoes provided in at least one embodiment of the present disclosure is shown.
[0131] Figures 6-8 The corresponding components shown are the same as those described above, and will not be repeated here.
[0132] Figure 9 It shows along Figure 8 A schematic diagram of the cross-section of line AA.
[0133] like Figure 9 The camera device 1000 also includes a local processing device 91.
[0134] It should be noted that the locations of the local processing unit 91 and the controller 100 are set according to the actual needs of the camera device 1000. Figure 9The locations shown are for illustrative purposes only. The description of the local processing device is the same as above and will not be repeated.
[0135] For example, the camera device 1000 also includes an energy storage battery 96 and a carbon dioxide tank 97, which can be replaced, for example, by opening the maintenance door 95.
[0136] For example, the controller 100 is also configured to control the camera device 1000 to enter a standby state in response to the environmental monitoring parameters continuously failing to meet the preset conditions during a first threshold period; and to control the camera device 1000 in the standby state to enter a working state in response to the environmental monitoring parameters continuously meeting the preset conditions during a second threshold period.
[0137] The first threshold period and the second threshold period can be equal or unequal. For example, the first threshold period and the second threshold period can be several days, such as 5 days or 6 days. This disclosure does not limit this.
[0138] Because the power consumption of the energy storage battery in the camera device is reduced to a minimum when in standby mode, such as only maintaining the measurement of environmental monitoring parameters, the power consumption of the camera device can be automatically reduced during periods when mosquito activity is low. This makes more efficient use of the energy storage battery, reduces the frequency of battery replacement, and thus lowers maintenance costs.
[0139] See also Figure 9 The insect inlet component 30 of the camera device 1000 includes a nested structure of multiple conical layers 302, and the insect inlet 301 includes an insect inlet channel 3010 disposed between two adjacent conical layers 302.
[0140] For example Figure 9 The insect inlet channel 3010 indicated by the dashed arrow, for example, multiple conical layers 302 may include two conical layers or three conical layers, etc. The number of conical layers can be set as needed, and this disclosure does not limit it.
[0141] In some embodiments of this disclosure, the plurality of conical layers 302 include adjacent conical inner layers 3021 and conical outer layers 3022. The diameter of the first inner layer at the first end of the conical inner layer 3021 is smaller than the diameter of the second inner layer at the second end of the conical inner layer 3021, and the diameter of the first outer layer at the first end of the conical outer layer 3022 is smaller than the diameter of the second outer layer at the second end of the conical inner layer 3021. The insect entry size of the insect entry channel 3010 is determined by the diameter of the first inner layer and the diameter of the first outer layer.
[0142] For example, an opening can be provided on the conical outer layer 3022 at the insect inlet 301 to house a first sensor 31 for monitoring carbon dioxide gas content. The side of the first sensor 31 that senses carbon dioxide gas content faces the insect inlet channel 3010, so that the first sensor 31 does not affect the insect size of the insect inlet channel 3010 due to its own size while sensing the carbon dioxide gas content.
[0143] For example, when the thickness of the conical inner layer is a, the insect entry size of the insect entry channel 3010 can be the diameter of the first outer layer minus half of the diameter of the first inner layer minus the thickness a.
[0144] For example, the insect entry size of the insect entry channel 3010 is 1.05-1.2 times the body length of the target mosquito. For example, the insect entry size can be set to 1.07, 1.09, 1.11, 1.13, 1.15, 1.17, or 1.19 times the body length of the target mosquito.
[0145] By setting the size of the insects entering the device to be 1.05-1.2 times larger than the target mosquito's body length, insects significantly larger than the target mosquito can be filtered out at the inlet. Furthermore, multiple through-holes on the camera plate, smaller than the target mosquito's body length, further filter out insects significantly smaller than the target mosquito. This ensures that all mosquitoes participating in the imaging within the insect storage channel are the target mosquitoes to be monitored, reducing the difficulty of filtering out insects using the identification algorithm model and improving the accuracy and efficiency of the imaging and identification process.
[0146] In some embodiments of this disclosure, the mosquito attractant device 10 includes an attractant box 103 that can be nested within the conical inner layer 3021, and the opening of the attractant box 103 faces the insect storage channel 20.
[0147] At least one embodiment of this disclosure also provides a method for photographing mosquitoes. Figure 10 A schematic flowchart of a method for photographing mosquitoes provided in at least one embodiment of this disclosure is shown.
[0148] like Figure 10 As shown, the imaging method includes steps S11 to S13, and the method is applied to the above-mentioned imaging device.
[0149] Step S11: Release at least one attractant provided by the mosquito attracting device through the insect inlet of the insect inlet component to attract corresponding mosquitoes in the external environment to gather around the insect inlet.
[0150] Step S12: Activate the air pressure control device to draw the target mosquitoes into the insect storage channel by the negative pressure provided by the air pressure control device, and attach them to the imaging surface of the camera tablet.
[0151] Step S13: Photograph the mosquitoes.
[0152] The insect inlet assembly is located at the first end of the insect storage channel, and the camera plate is located at the second end of the insect storage channel. The camera plate includes multiple through holes smaller than the body length of the target mosquito. The air pressure control device is located at the second end and is configured to provide negative pressure on the air inlet side facing the camera plate.
[0153] In some embodiments of this disclosure, step S11 of the above-described imaging method includes: controlling the rhythmic release of at least one luring source.
[0154] For example, the above-mentioned camera method also includes releasing carbon dioxide gas according to a preset first rhythm in response to environmental monitoring parameters meeting preset conditions:
[0155] During a first preset time period, carbon dioxide gas is controlled to be released through the insect inlet; the opening of the insect inlet faces the ground; in response to the end of the first preset time period, the release of carbon dioxide gas is controlled to stop, and a second preset time period is waited; in response to the end of the second preset time period, the gas pressure control device is controlled to be turned on during a third preset time period, wherein the duration of the second preset time period is longer than the duration of the first preset time period and longer than the duration of the third preset time period.
[0156] For example, step S13 in the above-described camera method includes starting shooting in response to the end of at least one preset first rhythm, wherein the air pressure control device is in an activated state during shooting.
[0157] For example, the camera plate is set as the gate of the first gate chamber assembly. The above-mentioned camera method further includes, in response to the end of shooting, closing the air pressure control device and switching the first gate chamber assembly to the open state; in response to the first gate chamber assembly being in the open state, activating the air pressure control device to collect the mosquitoes that have been photographed into the collector, wherein the camera plate is hidden when the first gate chamber assembly is in the open state, and the collector is set on the outlet side of the air pressure control device for providing positive pressure.
[0158] For example, a second gate chamber assembly is provided between the first gate chamber assembly and the insect storage channel, and a centralized camera chamber is provided between the first gate chamber assembly and the second gate chamber assembly. The above-mentioned camera method further includes keeping the second gate chamber assembly in an open state during a third preset time period so as to collect the target mosquitoes into the centralized camera chamber through an activated air pressure control device. When the second gate chamber assembly is in the open state, the insect storage channel and the centralized camera chamber are spatially connected.
[0159] For example, the above-mentioned camera method further includes determining the shooting interval based on at least one of the current shooting interval, the number of mosquitoes currently captured by the camera module, and the current environmental monitoring parameters, wherein the shooting interval is an integer multiple of the preset total duration of the first rhythm.
[0160] For example, step S13 in the above-mentioned camera method further includes: in response to the shooting interval not being reached and at least one preset first rhythm ending, switching the second gate chamber assembly to the closed state, turning off the air pressure control device, and re-executing the preset first rhythm; and in response to the shooting interval being reached and at least one preset first rhythm ending, starting the shooting.
[0161] For example, the above-mentioned camera method also includes uploading the current shooting data to the network in response to the current number of mosquitoes captured meeting a preset number threshold, wherein the current number of mosquitoes captured is locally identified.
[0162] For example, the above-mentioned camera method also includes setting the air volume value when the air pressure control device is activated, so that the target mosquitoes are evenly adsorbed on the shooting surface of the camera plate, wherein the air volume value ranges from 1.9 to 2.3 cubic meters per minute.
[0163] The technical effects of the imaging method for mosquitoes described in the above embodiments of this disclosure are the same as those of the imaging device for mosquitoes described above, and therefore will not be repeated.
[0164] The following points need to be clarified regarding this disclosure:

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
