Description

Technical Field

[0001] This invention relates to the technical field of remote pest monitoring devices, and specifically to an Internet-based remote monitoring device for forest pests. Background Technology

[0002] Pests have a significant impact on the healthy growth of trees, and pest monitoring and control are a crucial part of forest cultivation. Traditional forest pest monitoring mainly relies on manual patrols, which not only consumes a lot of manpower and resources, but also has a limited monitoring range and poor timeliness, making it difficult to detect and take control measures in the early stages of pest outbreaks. This is especially true in areas with complex terrain, where manual patrols are even more challenging.

[0003] Chinese utility model patent CN220545709U discloses a monitoring and early warning device for forestry planting pests and diseases, relating to the field of pest and disease monitoring and early warning technology. The device includes an insect collection box with an internal collection drawer and a handle. A sensor is installed on the bottom wall of the drawer. By incorporating a suction and cleaning component, when the insect-attracting lamp inside the transparent light box is turned on, pests are attracted to it and fly towards it. They are then electrocuted by an insecticidal grid covering the outside of the transparent light box and fall into the collection trough into the insect collection box. A fan inside the suction box operates, drawing pests from the surrounding area into the suction box through suction holes. The insects are then blown out through holes angled towards the insecticidal grid and electrocuted. Incidentally, the dead insects, which produce mucus and stick to the grid after electrocution, are blown into the collection trough and then into the insect collection box. This not only cleans the dead insects from the grid but also allows for the collection of pests at different heights outside the device.

[0004] After each test, the pest and disease monitoring and early warning devices for forestry planting require the collection trays to be thoroughly cleaned of pests before the next monitoring can be conducted. When the forest area is large and the devices are located far away, regular inspections are still necessary, which consumes a lot of manpower and is quite inconvenient for long-distance pest monitoring. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide an Internet-based remote monitoring device for forest pests, comprising a support frame, an insect collection box, an insect-attracting component, a control module, and a communication module. This Internet-based remote monitoring device for forest pests has the advantage of facilitating the monitoring of forest pests over long distances.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0007] A remote monitoring device for forest pests based on the Internet includes a support frame, an insect collection box, an insect-attracting component, a control module, and a communication module. The insect collection box is fixedly mounted on the support frame, and the insect-attracting component is disposed on the insect collection box. The insect-attracting component includes a first pipe, a second pipe, and a current detection module. The first pipe and the second pipe are located inside the insect collection box and are connected. The insect collection box has an insect-attracting opening, and the first pipe is connected to the insect-attracting opening. An insect-attracting lamp is installed on the first pipe. The second pipe is located between the insect-attracting opening and the insect-attracting lamp. The insect collection box is equipped with a vacuum pump for extracting gas from inside the insect collection box. The second pipe is located away from the first pipe. The device is equipped with a conductive rod and a conductive mesh plate.

A current detection module is electrically connected to both the conductive mesh plate and the conductive rod, and is used to energize the conductive mesh plate and the conductive rod. A control module is electrically connected to both the current detection module and the communication module. When insects pass through the conductive mesh plate and the conductive rod and enter the insect collection box, the current detection module transmits current change information to the control module. The control module calculates the insect density detection value based on the number of current change information, and then sends the insect density detection value to the cloud server through the communication module.

The communication module uses advanced wireless communication technology to stably and efficiently transmit monitoring data to the cloud server, which then determines whether to issue warnings to terminal devices based on preset thresholds. This achieves long-distance, real-time pest monitoring. Insects already present in the collection box do not affect the monitoring results, thus eliminating the need for frequent cleaning and significantly reducing workload. It is particularly suitable for applications in large, remote forest areas, effectively solving the problems of low efficiency and limited range associated with traditional manual patrols, and achieving the advantage of convenient long-distance pest monitoring in forest areas.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments. However, the scope of protection of this invention is not limited to the specific embodiments described below.

[0031] refer to Figure 1-6An internet-based remote monitoring device for forest pests includes a support frame 11, an insect collection box 12, an insect-attracting component, a control module 71, and a communication module 72. The insect collection box 12 is fixedly mounted on the support frame 11. The insect-attracting component is mounted on the insect collection box 12 and includes a first pipe 61, a second pipe 65, and a current detection module. The first pipe 61 and the second pipe 65 are located inside the insect collection box 12 and are connected. The insect collection box 12 has an insect-attracting opening 14, and the first pipe 61 is connected to the insect-attracting opening 14. An insect-attracting lamp 62 is installed on the first pipe 61. The second pipe 65 is located between the insect-attracting opening 14 and the insect-attracting lamp 62. The insect collection box 12 is equipped with a vacuum pump 13 for extracting gas from the insect collection box 12. The end of the second pipe 65 away from the first pipe 61 is provided with a conductive rod 67 and a conductive mesh plate 66. The upper end of the conductive mesh plate 66 is rotatably connected to the second pipe 65, so that the conductive mesh plate 66 hangs down naturally under the action of gravity. The conductive rod 67 is fixedly connected to the second pipe 65 and is located below the second pipe 65. There is a gap between the conductive mesh plate 66 and the conductive rod 67 to prevent accidental conduction between the conductive mesh plate 66 and the conductive rod 67. The current detection module is electrically connected to the conductive mesh plate 66 and the conductive rod 67 respectively. The current detection module is used to energize the conductive mesh plate 66 and the conductive rod 67. The control module 71 is electrically connected to the current detection module and the communication module 72 respectively. The control module 71 is a microprocessor and the communication module 72 is a 4G module. When insects pass through the conductive mesh plate 66 and the conductive rod 67 and enter the insect collection box 12, the current detection module transmits current change information to the control module 71. The control module 71 calculates the insect density detection value based on the number of current change information. The control module 71 sends the insect density detection value to the cloud server through the communication module 72.

[0032] The insect-attracting opening 14 is located above the insect-collecting box 12, and the first pipe 61 is located below the insect-attracting opening 14. A support plate 21 is fixedly connected to the support frame 11, and a conical reflective block 22 is fixedly connected to the support plate 21. The conical reflective block 22 is located above the insect-attracting opening 14, and its width gradually increases from bottom to top. An arc-shaped reflective surface 23 is provided on the lower side of the conical reflective block 22. A semi-transparent light-transmitting film 24 is provided on the arc-shaped reflective surface 23. A reflector plate 63 is provided at the lower end of the first pipe 61, and a light-transmitting baffle 64 is fixedly connected to the first pipe 61. The insect-attracting lamp 62 is located between the reflector plate 63 and the light-transmitting baffle 64. An inclined plate 25 is fixedly connected to the insect-attracting opening 14, guiding insects into the opening and increasing the success rate of insect trapping.

[0033] The insect collection box 12 has a through groove 31 at its lower end and a bottom plate 32 at its bottom that blocks the through groove 31. The bottom plate 32 is fitted with screws 35 that are connected to the insect collection box 12. The bottom plate 32 is provided with a first rocker arm 33 and a second rocker arm 34. Both ends of the first rocker arm 33 and the second rocker arm 34 are rotatably connected to the bottom plate 32 and the insect collection box 12, respectively. The length of the first rocker arm 33 is less than the length of the second rocker arm 34.

[0034] A support frame 11 is equipped with an inclined frame 41, on which a solar panel 42 is fixedly mounted. The solar panel 42 is inclined. A water storage tank 51 is fixedly connected to the support frame 11, located directly below the lower end of the solar panel 42. The upper end of the water storage tank 51 has an opening 52. An inclined filter plate 53 located at the opening 52 is fixedly connected to the water storage tank 51. A sealing plate 54 is fixedly connected to the lower side of the inclined filter plate 53. The width of the sealing plate 54 is smaller than the width of the inclined filter plate 53. A drain pipe 55 is connected to the lower end of the water storage tank 51, and a water valve 56 is installed on the drain pipe 55. The upper end of the first rocker arm 33 is inclined towards the water storage tank 51. The inclined setting of the solar panel 42 allows it to fully receive sunlight for photovoltaic power generation, enabling power supply, especially suitable for remote forest areas. The width of the sealing plate 54 is smaller than the width of the inclined filter plate 53 to prevent the sealing plate 54 from completely blocking the inclined filter plate 53, ensuring that water can flow through the inclined filter plate 53 into the water storage tank 51.

[0035] The support frame 11 is rotatably connected to the connecting seat 43, the connecting seat 43 is rotatably connected to the threaded sleeve 44, the threaded sleeve 44 is threadedly connected to the screw 45, the upper end of the screw 45 is rotatably connected to the inclined frame 41, the upper end of the threaded sleeve 44 is provided with a limiting ring 46 that engages with the upper surface of the connecting seat 43, and the lower end of the threaded sleeve 44 is provided with an anti-slip protrusion 47 that engages with the lower surface of the connecting seat 43.

[0036] The insect collection box 12 has a compartment 15, and the air pump 13 is located inside the compartment 15. The insect collection box 12 has a heat dissipation window 16 that communicates with the compartment 15, allowing air circulation inside and outside the compartment 15, which is beneficial for heat dissipation of the air pump 13. The upper end of the compartment 15 has an inspection port 17. The insect collection box 12 is detachably connected to a cover plate 18. Removing the cover plate 18 allows for convenient maintenance and repair of the air pump 13 through the inspection port 17.

[0037] The current detection module includes an oscillating boost circuit 73, a voltage doubler rectifier circuit 74, and a current detection unit 75. The oscillating boost circuit 73 is provided with a DC power supply connection terminal and is electrically connected to the voltage doubler rectifier circuit 74. The voltage doubler rectifier circuit 74 is electrically connected to the conductive mesh plate 66 and the conductive rod 67, respectively. The voltage doubler rectifier circuit 74 is used to apply a voltage of 1500V to the conductive mesh plate 66 and the conductive rod 67. The current detection unit 75 is electrically connected to the voltage doubler rectifier circuit 74 and is used to detect the current in the conductive mesh plate 66 and the conductive rod 67. The current detection unit 75 is electrically connected to the control module 71 and transmits current change information to the control module 71.

[0038] The oscillating boost circuit 73 includes a feedback coil N1, a primary coil N2, a secondary coil N3, a transistor D882, and a feedback resistor R1. Initially, current cannot flow directly through transistor D882 to the primary coil N2; it must first flow through the feedback coil N1 to both transistor D882 and the primary coil N2, with the primary coil N2 experiencing a relatively small current. The feedback coil N1 slows down the current increase, allowing for a certain time interval between the current rising to a level sufficient to turn on transistor D882. When the current flowing from the feedback coil N1 to transistor D882 becomes sufficient to turn on D882, the primary coil N2 is directly connected to the DC power supply, increasing the primary coil N2 current and decreasing the feedback coil N1 current. When the feedback coil N1 current decreases to a level insufficient to turn on transistor D882, D882 disconnects, reducing the electromotive force across the primary coil N2. The repeated changes in current in the primary coil N2 induce an electromotive force (EMF) in the secondary coil N3. This EMF is then electrically connected to the voltage multiplier rectifier circuit 74, which outputs alternating current. The secondary coil N3 has more turns than both the primary coil N2 and the feedback coil N1, resulting in a larger induced EMF and thus enabling voltage boosting.

[0039] The voltage doubler rectifier circuit 74 includes diode D1, capacitor C1, diode D2, capacitor C2, diode D3, capacitor C3, and bleeder resistor R2. The AC output from the secondary coil generates a reciprocating current. When the forward current passes through capacitor C1, it charges the capacitor. When it turns into a reverse current, diode D1 limits the current direction, causing the current to flow sequentially through capacitor C1, diode D2, and capacitor C2. The secondary coil N3 and capacitor C1 simultaneously charge capacitor C2, making the voltage of capacitor C2 greater than the voltage of capacitor C1. The current output from the secondary coil N3 changes direction again to a forward current, causing the current to flow sequentially through capacitor C2, diode D3, and capacitor C3. The secondary coil N3 and capacitor C2 simultaneously charge capacitor C3, making the voltage of capacitor C3 greater than the voltage of capacitor C2, thus achieving the rectification and voltage boosting function. The two ends of capacitor C3 are electrically connected to the conductive mesh plate 66 and the conductive rod 67, respectively, allowing the boosted DC current to be applied to the conductive mesh plate 66 and the conductive rod 67. The current detection unit 75 is a galvanometer connected between capacitor C3 and conductive mesh plate 66, enabling it to monitor the current in conductive mesh plate 66. The bleeder resistor R2 is used to eliminate residual voltage in the circuit, preventing residual current from posing a safety hazard to the equipment after power failure.

[0040] The DC power supply connection terminal is equipped with a detection circuit switch 76, which is electrically connected to the control module 71. The communication module 72 is connected to the cloud server, which in turn is connected to the device terminal. The cloud server communicates with the device terminal via the Internet. The cloud server stores alarm thresholds. When the detected pest density exceeds the alarm threshold, the cloud server sends an alarm message to the device terminal, enabling staff to receive the alarm message on the device terminal and receive timely warnings about pests.

[0041] The support frame 11 is fixedly installed with an electrical box 19, which contains a storage battery. The oscillation boost circuit 73, the voltage doubler rectifier circuit 74, the current detection unit 75, the control module 71, and the communication module 72 are all located inside the electrical box 19. The solar panel 42 is electrically connected to the storage battery. The storage battery is electrically connected to the DC power supply terminal, the insect-attracting lamp 62, the air pump 13, the control module 71, and the communication module 72, respectively. The storage battery is used to supply power to the DC power supply terminal, the insect-attracting lamp 62, the air pump 13, the control module 71, and the communication module 72.

[0042] In use, the control module 71 controls the insect-attracting lamp 62 to turn on, and simultaneously starts the air pump 13. The insect-attracting lamp 62 emits light to attract insects. The air pump 13 extracts the gas from the insect collection box 12, creating a negative pressure environment inside the insect collection box 12. This causes air to flow sequentially through the insect-attracting opening 14, the first pipe 61, the second pipe 65, and the insect collection box 12. When no insects are in contact, the airflow can directly pass through the conductive mesh plate 66, preventing the airflow from pushing the conductive mesh plate 66 to rotate. When an insect moves to the insect-attracting opening 14, the air carries the insect through the insect-attracting opening 14 and into the first pipe 61 and the second pipe 65. The insect then moves to the conductive mesh plate 66 and the conductive rod 67, comes into contact with them, and is pushed to rotate by the airflow. This allows the insect to push aside the conductive mesh plate 66 and enter the insect collection box 12. Because the current detection module applies voltage to the conductive mesh plate 66 and the conductive rod 67, a current flows when an insect touches these surfaces. This utilizes the insect's conductivity to change the current between the mesh plate and the rod 67. The current detection module captures this current change in real time and converts it into an electrical signal, feeding it back to the control module 71. Each insect passing through generates a current change, and the current detection module transmits this information to the control module 71. The control module 71 counts the received current change data and calculates the pest density detection value per unit time. Subsequently, the control module 71 packages the calculated pest density detection value through the communication module 72 and sends it wirelessly to the cloud server, enabling remote transmission and storage of pest data. This allows management personnel to easily obtain real-time pest monitoring information from the cloud server via terminal devices.

[0043] This embodiment has the following advantages:

[0044] The current detection module monitors the current changes between the conductive mesh plate 66 and the conductive rod 67 in real time, accurately detecting whether insects are passing through, providing data for the control module 71 to calculate pest density. The control module 71 counts pest monitoring information over a certain period to determine the number of insects entering the insect collection box 12 through the first pipe 61 and the second pipe 65, thus enabling insect density monitoring. The communication module 72 uses advanced wireless communication technology to stably and efficiently transmit monitoring data to the cloud server, which then determines whether to send an early warning to the terminal device based on a preset threshold. This achieves long-distance, real-time pest monitoring. Insects already present in the insect collection box 12 do not affect the monitoring results, thus eliminating the need for frequent cleaning of the insect collection box 12, significantly reducing workload. This is particularly suitable for applications in large, remote forest areas, effectively solving the problems of low efficiency and limited range associated with traditional manual patrols, and achieving the advantage of convenient long-distance pest monitoring in forest areas.

[0045] The voltage doubler rectifier circuit 74 provides at least 700V, ensuring effective current changes for insects of different sizes, thus improving detection sensitivity and reliability. It also generates a sufficiently large current to shock the insects, effectively killing them and preventing them from escaping from the insect collection box 12.

[0046] The second pipe 65 is rotatably connected to the second pipe 65, so that when insects pass by, they can push the conductive mesh plate 66 to rotate, allowing the insects to push the conductive mesh plate 66 from the second pipe 65 into the insect collection box 12.

[0047] When the conductive mesh plate 66 is pushed by an insect, the end of the conductive mesh plate 66 away from the second pipe 65 tilts downward, allowing the insect to move diagonally downward along the tilt direction of the conductive mesh plate 66 as it pushes the conductive mesh plate 66. Positioning the conductive rod 67 below the conductive mesh plate 66 increases the probability that the insect moving downward along the tilt direction of the conductive mesh plate 66 will come into contact with the conductive rod 67, thereby increasing the probability of simultaneous contact between the insect, the conductive rod 67, and the conductive mesh plate 66, ensuring the accuracy of monitoring.

[0048] When the device is not in a monitoring period or needs maintenance, the control module 71 can control the detection circuit switch 76 to disconnect, cutting off the connection between the oscillation boost circuit 73 and the DC power supply, thus preventing the conductive mesh plate 66 and the conductive rod 67 from being continuously energized, thereby reducing energy consumption, improving safety, and facilitating use.

[0049] The insect-attracting opening 14 is located on the upper side of the insect collection box 12. It can cause insects to fall downwards into the insect-attracting opening 14 by gravity, thereby increasing the success rate of trapping and ensuring that more insects can be captured by the current detection module, thus improving the accuracy of pest density detection.

[0050] The cone-shaped reflector 22 can reflect and diffuse the light emitted by the insect-attracting lamp 62 in all directions, expanding the illumination range of the insect-attracting lamp 62 and enhancing the attraction effect on insects from different directions.

[0051] The semi-transparent light-transmitting film 24 absorbs light, reducing the intensity of light reflected from the curved reflective surface 23. This ensures that the intensity of light reflected from the curved reflective surface 23 is less than the intensity of light emitted by the insect-attracting lamp 62, increasing the likelihood that insects at the conical reflective block 22 will be attracted by the insect-attracting lamp 62.

[0052] The reflector 63 reflects the light from the bottom of the insect-attracting lamp 62 out of the first pipe 61, increasing the intensity of the light emitted from the first pipe 61 and increasing the success rate of trapping insects.

[0053] When it is necessary to clean the insects in the insect collection box 12, loosen the screw 35 by rotating it, and the base plate 32 will move downward under the action of gravity. Since the length of the first rocker arm 33 is less than that of the second rocker arm 34, the base plate 32 will be tilted, and the through groove 31 will gradually open as the base plate 32 rotates. The insects in the insect collection box 12 can slide out of the through groove 31 along the tilted base plate 32, achieving quick cleaning. After cleaning, push the base plate 32 upward and fix the base plate 32 with the screw 35 to reseal the through groove 31.

[0054] When it rains, rainwater slides down the surface of the solar panel 42 onto the inclined filter plate 53. The inclined filter plate 53 filters out impurities such as leaves from the rainwater. The filtered rainwater then enters the water storage tank 51 through the opening 52. When it is necessary to clean the insect collection box 12, the bottom plate 32 moves downward after rotating the screw 35. Because the upper end of the first rocker arm 33 is tilted towards the water storage tank 51, the upper end of the bottom plate 32 tilts towards the water storage tank 51 when the bottom plate 32 is opened, causing the upper end of the bottom plate 32 to move below the drain pipe 55. Then, the water valve 56 is opened, allowing the water in the water storage tank 51 to flow through the drain pipe 55 onto the bottom plate 32, which can wash away the insects on the bottom plate 32 and facilitate cleaning the bottom plate 32. Since the device needs to be installed outdoors for extended periods, insects that fall onto the base plate 32 become difficult to remove without moisture after prolonged drying and sticking. Furthermore, some areas in the forest are far from water sources. The water storage tank 51 addresses this problem by solving the difficulty in removing insects that have dried and hardened on the base plate 32, thus facilitating use. When water is not needed, storing water in the tank 51 will not affect the normal operation of the device.

[0055] When the tilt angle of the solar panel 42 needs to be adjusted, hold the anti-slip protrusion 47 and rotate the threaded sleeve 44. The threaded sleeve 44 drives the screw 45, which is threaded to it, to move axially. The screw 45 drives the tilting frame 41 to rotate on the support frame 11, thereby adjusting the angle of the tilting frame 41 and the solar panel 42 so that the solar panel 42 faces the sun. The anti-slip protrusion 47 also increases the friction when rotating the threaded sleeve 44, making it easier to operate. The limiting ring 46 is engaged with the upper surface of the connecting seat 43, and the anti-slip protrusion 47 is engaged with the lower surface of the connecting seat 43 to prevent the threaded sleeve 44 from falling off the connecting seat 43.

[0056] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the invention.
