Abstract
Description
Technical Field
[0001] The present application relates to an insect catching device, and in particular to an insect catching device and a counting method for an orchard. Background Art
[0002] In modern agriculture, collecting data such as the types and density of pests in orchards is an important technical means for pest control, and the insect trap is the main equipment for collecting and counting pest data. In the prior art, the insect trap mainly includes a trapping device for trapping pests, a counting device for counting, and an insect storage device. The trapping device mainly includes an insect trap core or an insect trap lamp; the counting device mainly arranges a photoelectric sensor in the insect falling channel. When the pests enter the insect storage device through the insect falling channel, the photoelectric sensor will output a corresponding number of pulse signals, and the number of pests can be counted by counting the number of pulse signals. The above counting device has the following technical problems: 1. The counting accuracy is poor, and repeated counting will occur when the pests move back and forth in the insect falling channel; 2. The individual size of the pests cannot be distinguished; 3. The photoelectric sensor used for counting is easily contaminated, requires frequent maintenance, and affects the counting accuracy.
[0003] To solve the above technical problem 1, the Chinese patent with application number 201911264019.6 and the name of insect catching device and counting method thereof discloses that two sensors are set at intervals in the channel, and the insects are counted only when the two sensors detect the signals of the insects at the same time. This solution can improve the accuracy of pest counting to a certain extent, but it still has its drawbacks. For example, when the interval between the two sensors is far, many individual smaller pests cannot block the two sensors at the same time when passing by, and thus are missed; and when the interval between the two sensors is close, the pests will still be repeatedly counted by the two sensors when moving back and forth in the channel. Therefore, the accuracy of pest counting in the above technical solution still needs to be improved. And the above technical solution still has the technical problem of being unable to detect the size of individual pests. In the prior art, pest images are mainly obtained by cameras, and then the types and sizes of pests are identified by image analysis algorithms. However, this technical solution has high requirements for software and hardware, and is mainly used in scientific research projects, and cannot be widely used in pest control applications in orchards.

[0061] See also Figures 1 to 3 , the present application provides an insect catching device for an orchard. The insect catching device for an orchard can be applied to orchards such as pear orchards and orange orchards, and is used to count and analyze the types and densities of pests in the orchard. The insect catching device for an orchard can be directly hung on a fruit tree by a rope, or it can be installed in an orchard by a mounting pole with a certain height. The insect catching device for an orchard can be used to count the number of pests, and to classify pests according to their individual sizes, thereby providing an accurate data basis for pest analysis and pest control in the orchard. In the present application, the insect catching device for an orchard does not require the use of a photoelectric sensor, which is convenient for daily maintenance, and can avoid counting errors caused by contamination of the photoelectric sensor. In addition, through the cooperation of a negative pressure fan and a booster valve, it can prevent misjudgment of counting caused by pests moving back and forth in the insect falling channel, thereby improving the accuracy of pest counting.
[0062] like Figure 1 As shown, this embodiment provides an insect catching device for an orchard. The insect catching device for an orchard comprises: an insect trapping lamp 1, an insect receiving tray 2, an insect falling channel 3, an insect storage tube 4, a rotating disk 5 and a counting component 6.
[0063] The insect-attracting lamp 1 can generate specific light such as ultraviolet rays that can attract pests. An electric shock net 12 is arranged on the periphery of the insect-attracting lamp 1. The electric shock net includes two meshes arranged opposite to each other. The two meshes are arranged with an interval of 1-2 cm and are respectively connected to the positive and negative electrodes of the power supply. The electric shock net 12 is used to stun the pests. When the pests are attracted to the insect-attracting lamp and approach it, the pests contact the positive and negative electrodes of the electric shock net, so that the pests are stunned. When the pests are electrocuted, the working current of the electric shock net 12 will surge. Therefore, by detecting whether the working current of the electric shock net surges, it can be determined whether the pests are electrocuted by the electric shock net 12 and fall onto the insect receiving tray 2. Figure 1 As shown, in order to prevent rainwater or other debris from entering the insect-falling channel, a conical rain shelter 11 is provided on the top of the insect-attracting lamp.
[0064] The insect receiving tray 2 is arranged below the insect attracting lamp 1, and the insect receiving tray 2 is used to collect the pests that are stunned and fall; the insect receiving tray 2 is funnel-shaped and has an insect falling hole 21 in the middle, and the insect falling hole 21 is connected to an insect falling channel 3; the tail end of the insect falling channel 3 is connected to an insect storage tube 4 for storing pests.
[0065] like Figure 2 As shown, the counting component 6 includes a current sensor, a boost valve 62, a negative pressure fan 61 and a counting sensor component.
[0066] The current sensor is arranged on the power supply harness of the electric shock net 12, and the current sensor is used to detect the working current of the electric shock net 12. By detecting the working current of the electric shock net 12, it can be detected whether the pests are stunned by the electric shock net 12 and fall into the insect receiving tray 2.
[0067] like Figure 2 As shown, the counting sensor assembly is arranged in the middle and upper section of the insect falling channel 3, and the counting sensor assembly is used to count the individual size and number of the pests. The counting sensor assembly includes a micro switch 63 and a capacitive sensor 64.
[0068] The negative pressure fan 61 is connected to the middle and lower sections of the insect falling channel 3. The negative pressure fan 61 is used to start working for a preset time after the current sensor detects a sudden increase in the working current (for example, the current sensor starts working 0.5 seconds after detecting a sudden increase in the working current). The preset time is based on the time required for the pests to be stunned and fall into the insect falling channel. Among them, the negative pressure fan refers to a fan that generates negative pressure in the middle and lower sections of the insect falling channel when working, so that the air in the insect falling channel flows from top to bottom. The negative pressure fan 61 sucks the air in the insect falling channel 3, such as Figure 2 As shown, when the negative pressure fan 61 sucks the air in the insect falling channel 3, the air and the pests pass through the counting sensor assembly from top to bottom. Therefore, it is possible to prevent the pests from moving up and down in the insect falling channel 3, that is, to prevent the pests from moving back and forth in front of the counting sensor, thereby causing repeated counting. In the prior art, many pests do not die immediately after being electrocuted by the electric shock net, and they will flap their wings during the falling process, so they may move back and forth up and down in the insect falling channel 3, thereby causing repeated counting. In this embodiment, the negative pressure fan sucks the air in the insect falling channel from the bottom, so that the pests move downward together with the air, and prevent the pests from moving back and forth in front of the counting sensor, thereby improving the accuracy of pest counting.
[0069] like Figure 2As shown, the boost valve 62 is rotatably arranged at the tail end of the insect falling channel 3, and the boost valve 62 is in a normally open state under the action of its own weight, and the boost valve 62 closes the tail end of the insect falling channel 3 under the airflow suction generated by the negative pressure fan 61 to increase the flow rate of the air in the insect falling channel 3 flowing through the counting sensor assembly. The boost valve 62 means that when the valve is closed, the flow rate of the air in the insect falling channel can be increased, that is, the pressure difference of the negative pressure is increased to increase the air flow rate. The boost valve includes a valve plate and a rotating shaft, the shape of the valve plate is adapted to the cross-section of the insect falling channel, the rotating shaft is arranged on the surface of the valve plate in parallel with the valve plate, and the two ends of the rotating shaft are hinged to the inner wall of the insect falling channel; the rotating shaft is eccentrically arranged on the surface of the valve plate, dividing the valve plate into a large surface with a larger area and a small surface with a smaller area.
[0070] When the negative pressure fan 61 is started, the airflow at both ends of the insect falling channel 3 is sucked away by the negative pressure fan 61, so that an upward airflow is generated at the tail end of the insect falling channel 3, and the airflow overcomes the weight of the boost valve 62, so that the boost valve 62 closes the tail end of the insect falling channel 3, and the airflow from top to bottom of the insect falling channel 3 increases, so a smaller negative pressure fan 61 can be used to generate a larger airflow. The insect catching device for orchards can be used to catch and count various pests such as pear psylla, pear yellow aphid, pear gall moth, pear flower bug, peach borer, etc. For example, in some embodiments, the natural falling speed of pests in the orchard after being stunned is about 1-2m / s. When the boost valve is closed, the air flow speed generated by the negative pressure fan 61 in the insect falling channel is about 5-6m / s, while the normal flying speed of the pests when they are not stunned is about 4.5m / s. That is, the air flow speed in the insect falling channel generated by the negative pressure fan is greater than the normal flying speed of the pests, so that the pests cannot fly upward in the insect falling channel and can only move downward, thereby avoiding repeated counting of pests.
[0071] like Figure 2 As shown, in this embodiment, the counting sensor assembly includes a micro switch 63 and a capacitive sensor 64 .
[0072] The micro switch 63 includes a main body 632 and a swing arm 631 hinged on the main body; the capacitive sensor 64 includes a sensing unit 641 and a signal processing unit 642 .
[0073] The main body 632 of the micro switch 63 and the signal processing unit are arranged outside the insect falling channel 3, and the swing arm 631 extends into the insect falling channel 3. Therefore, when the pest falls into the insect falling channel and is sucked downward by the negative pressure fan, the pest collides with the swing arm 631. When the pest individual is large, the pest causes the swing arm 631 to swing, and the main body 632 generates a pulse signal; when the pest individual is small, the impact force of the pest on the swing arm 631 is small, and the main body 632 cannot generate a pulse signal.
[0074] The sensing unit 641 of the capacitive sensor 64 is arranged at the end of the swing arm 631, and the sensing unit 641 is electrically connected to the signal processing unit 642 through a wire 643; the sensing unit includes a sensing electrode, a reference electrode and an insulating layer arranged between the sensing electrode and the reference electrode. When the pest contacts the sensing unit 641, the capacitance value of the sensing unit changes, and is detected by the signal processing unit to generate a corresponding pulse signal. Therefore, once the pest contacts the sensing unit 641, the signal processing unit can generate a corresponding pulse signal, that is, each pest can be detected. In the prior art, the sensing unit 641 and the signal processing unit 642 of the capacitive sensor 64 are packaged together, and in this embodiment, the existing capacitive sensor is split into the sensing unit 641 and the signal processing unit 642 arranged at different positions. Compared with setting the entire capacitive sensor 64 on the swing arm, the weight on the swing arm can be reduced, the sensitivity of the swing arm during detection is improved, and the detection accuracy is improved.
[0075] Each pest that enters the insect-falling channel can be detected by the capacitive sensor 64, and larger pests can be detected by the micro switch. Therefore, in this embodiment, when both the micro switch 63 and the capacitive sensor 64 detect the pest, the pest is marked as a larger first-category pest, and the first-category pest is counted; when only the capacitive sensor detects the pest, the pest is marked as a smaller second-category pest, and the second-category pest is counted. For example, the insect-catching device for orchards can mark the pear gall moth as a first-category pest and count it, and mark the smaller pear psylla and pear yellow aphid as a second-category pest and count it.
[0076] In the related art, the micro switch requires a large force to drive the swing arm to swing, thereby generating a corresponding pulse signal. This force is beyond the impact force of most pests when they fall. In this embodiment, the speed of the pests falling can be increased by the negative pressure fan 61, thereby increasing the impact force of the pests hitting the swing arm, so that the micro switch can be used to count pests with larger volumes.
[0077] In the above embodiment, the insect catching device for orchards is provided with a counting component on the insect falling channel, and the counting component includes a current sensor, a boost valve, a negative pressure fan and a counting sensor component. The current sensor detects the current change of the electric shock net to detect whether pests fall into the insect receiving tray, and when the pests fall into the insect falling channel, the boost valve cooperates with the negative pressure fan to control the flow direction and flow rate of the air in the insect falling channel, so that the pests pass through the counting sensor component with the airflow, thereby avoiding repeated counting caused by the movement of pests in the insect falling channel and improving the counting accuracy.
[0078] The counting sensor assembly in the present application is not limited to the combination of the micro switch 63 and the capacitive sensor 64 described in the above embodiment. In other embodiments, when it is not necessary to classify the pests by size, only one of the micro switch 63 or the capacitive sensor 64 may be provided. Alternatively, in some embodiments, a photoelectric sensor may be used instead of the micro switch or the capacitive sensor 64.
[0079] like Figure 1 As shown, the insect catching device for orchards includes a plurality of insect storage tubes 4, which are arranged on a rotating disk 5, and the rotating disk 5 is connected to a driving motor, which drives the rotating disk 5 to rotate. The insect storage tubes 4 are marked as a first insect storage tube for storing a first type of pests and a second insect storage tube for storing a second type of pests.
[0080] When the counting sensor assembly marks the first type of pests, the rotating disk controls the first insect storage tube to rotate below the insect falling channel; when the counting sensor assembly marks the second type of pests, the rotating disk controls the second insect storage tube to rotate below the insect falling channel.
[0081] like Figure 2 As shown, in one embodiment, a plurality of air guide holes penetrating the sensing electrode, the insulating layer and the reference electrode are provided on the surface of the sensing unit to reduce the force exerted on the swing arm by the airflow generated by the negative pressure fan.
[0082] In this embodiment, the surface of the sensing unit is provided with air guide holes, so that when the same wind resistance is generated under the suction of the negative pressure fan, the area of the sensing unit can be made larger, thereby increasing the probability of pests contacting the sensing unit and improving the accuracy of pest counting.
[0083] like Figure 3 As shown, in another embodiment, a counting method of an insect catching device for an orchard is provided. The insect catching device for an orchard is the insect catching device for an orchard described in the above embodiment. The counting method of the insect catching device for an orchard comprises the following steps:
[0084] S301, enabling the current sensor to detect the working current of the electric shock network;
[0085] S302, when a sudden rise in the working current is detected, a negative pressure fan connected to the middle and lower sections of the insect falling channel is started to work for a preset time to suck the air in the insect falling channel so that the air and the pests pass through the counting sensor assembly from top to bottom;
[0086] S303, when the negative pressure fan is working, the booster valve arranged at the tail end of the insect falling channel closes the tail end of the insect falling channel due to the airflow suction force generated by the negative pressure fan, so as to increase the flow rate of the air in the insect falling channel flowing through the counting sensor assembly;
[0087] S304: Count the individual sizes and numbers of pests through the counting sensor assembly.
[0088] like Figure 2 As shown, in one embodiment, the counting sensor assembly includes a micro switch 63 and a capacitive sensor 64; the micro switch includes a main body and a swing arm hinged on the main body; the capacitive sensor includes a sensing unit and a signal processing unit; the main body and the signal processing unit are arranged outside the insect falling channel, the swing arm extends into the insect falling channel, and the sensing unit is arranged at the end of the swing arm and is electrically connected to the signal processing unit.
[0089] The method of counting the individual sizes and numbers of pests by means of the counting sensor assembly comprises the steps of:
[0090] When the micro switch and the capacitive sensor both detect the pest, the pest is marked as a first-category pest with a larger size, and the first-category pests are counted;
[0091] When the pest is detected only by the capacitive sensor, the pest is marked as a second type of pest with a smaller size, and the second type of pests are counted.
[0092] In one embodiment, the method further comprises the steps of:
