An oviposition trap for the oriental armyworm

Abstract

This invention relates to the field of agricultural engineering technology and relates to a device for attracting and destroying eggs of armyworms. The invention addresses the problems of existing methods that involve burning piles of grass containing armyworm eggs, which are characterized by low automation and high time and labor costs. The invention uses a control module to move one rotating component to the outside of the casing, while simultaneously controlling another rotating component to move inside the casing near a microwave radiation device. When a preset number of days have elapsed since the last egg-destroying operation, the positions of the two rotating components are swapped, with one component moving inside the casing near the microwave radiation device and the other moving outside. When the control module detects rain via a rain sensor, humidity below a threshold via a humidity sensor, or a battery level warning via a power monitoring module, it controls the rotating component located outside the casing to move inside. This invention is used for attracting and destroying eggs.

Description

Technical Field

[0001] This invention relates to the field of agricultural engineering technology. Background Technology

[0002] Armyworm adults have a strong reproductive capacity. Females typically begin laying eggs 2-3 days after emergence, and the entire process from egg-laying to hatching takes only 4-7 days. Each female can lay eggs multiple times, producing a total of approximately 500 to 1000 eggs during her lifespan. Without external intervention and in relatively suitable environments, the number of armyworm larvae can rapidly increase, causing severe damage to agriculture in the affected area.

[0003] The current popular method for killing armyworms is to attract and kill adult armyworms using black light or a sugar-vinegar mixture.

[0004] Many flying insects are attracted to light, and using black light lamps cannot specifically attract adult armyworms, and will also kill beneficial insects that are attracted to light at the same time.

[0005] While the sweet and sour mixture is more targeted, it is prone to evaporation under open-air conditions. In addition, the sweet and sour mixture will deteriorate over time, resulting in a decrease in its attractiveness to adult armyworms.

[0006] Armyworms are highly selective in their egg-laying location, laying eggs mostly at the tips of the top three or four leaves of crop plants or inside dead leaves and leaf sheaths. In response to this characteristic, the traditional practice is to place a pile of straw at intervals in the field to lure adult armyworms to lay eggs. The straw piles are replaced every five days or so, and the straw piles with eggs are put into a fire to be burned. However, this method has a low degree of automation and is time-consuming and labor-intensive. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of low automation and time and labor consumption in the existing method of burning grass piles containing insect eggs in a fire. This invention proposes an egg-attracting and egg-killing device for armyworms.

[0008] An egg-attracting and egg-destroying device for armyworms, the device comprising a shell, a gantry assembly, two rotating and moving assemblies, a control module, a raindrop sensor, a humidity sensor, a microwave radiation device, a battery, and a power monitoring module;

[0009] The outer shell covers the gantry assembly, and the top beam of the gantry assembly extends out of the outer shell at both ends; two rotating and moving components can rotate on their own axis and carry the straw placed on them to move horizontally along the top beam of the gantry assembly; the microwave radiation device and control module are both housed inside the outer shell;

[0010] The control module is used to control one rotating moving component to move to the outside of the housing, while simultaneously controlling another rotating moving component to move to the inside of the housing closer to the microwave radiation device. When the time since the last egg-killing reaches a preset number of days, the positions of the two rotating moving components are swapped, controlling one rotating moving component to move to the inside of the housing closer to the microwave radiation device, while simultaneously controlling the other rotating moving component to move to the outside of the housing. It is also used to control the rotating moving component located outside the housing to move to the inside of the housing when rain is detected by a raindrop sensor, humidity is detected to be below a threshold by a humidity sensor, or battery level is detected to be at a warning value by a power monitoring module.

[0011] Preferably, the gantry assembly includes two gantry support frames;

[0012] The device also includes an outer shell support column, a short support column, a front clamping plate, a rear clamping plate, a heat dissipation channel, and an open shell;

[0013] Two gantry support frames are arranged in parallel, and two rotating and moving components are located between the two gantry support frames. The bottom surface of the top beam of each gantry support frame is symmetrically connected to two short columns. The top beam of the gantry support frame at the rear end is connected to the two connected short columns via a rear clamping plate, and the top beam of the gantry support frame at the front end is connected to the two connected short columns via a front clamping plate. The outer shell covers the top beam, front clamping plate, rear clamping plate, and short columns of the gantry support frame. The columns at both ends of the gantry frame assembly are exposed outside the outer shell. The outer shell support columns are supported on the bottom plate of the outer shell, and the height after support is flush with the height of the columns of the gantry frame assembly.

[0014] A through hole is provided on the front clamp plate, and the position of the through hole is opposite to the position of the microwave transmitting box in the microwave radiation device. The back of the front clamp plate is connected to the open shell, and the open shell is connected to the inner wall of the through hole of the front clamp plate. The opening of the open shell faces the through hole. A heat dissipation hole is provided on the rear shell of the open shell, and a through hole is provided on the front plate of the shell. The heat dissipation channel passes through the through hole to lead the heat discharged from the heat dissipation hole on the open shell to the outside of the shell.

[0015] Preferably, the microwave radiation device includes a microwave generator, a microwave transmitting box, a first microwave transmitting plate, and a second microwave transmitting plate;

[0016] The microwave generator is mounted on the rear clamping plate between the rear clamping plate and the outer casing;

[0017] The microwave transmitter box is mounted on the bottom plate of the outer shell between the front and rear clamping plates, and is positioned close to the rear clamping plate.

[0018] The first and second microwave transmitting plates are installed inside the microwave transmitting box.

[0019] The microwaves generated by the microwave generator are emitted to the straw through the first microwave emitting plate and the second microwave emitting plate. A second heat dissipation hole is opened on the back plate of the outer casing corresponding to the position of the microwave generator.

[0020] Preferably, the device further includes two small rain covers and two large rain covers;

[0021] One small rain cover is provided on each of the front and rear surfaces of the outer casing. The two small rain covers are used to cover the outlet of the heat dissipation channel and the No. 2 heat dissipation hole on the outer casing, respectively.

[0022] Two large rain covers are connected to both ends of the top plate of the outer shell, and the two large rain covers cover the columns of the two gantry support frames inside.

[0023] Preferably, the device further includes a two-way spring hinge, a rainproof door, and a shielding door;

[0024] On the opposite side walls of the two short pillars on the same side, there is a rain door connected to each of the short pillars. Each rain door is connected to the short pillar by a two-way spring hinge.

[0025] The front cover of the microwave transmitter box is connected to two shielding doors at each end by two bidirectional spring hinges, and the back of the open shell is also connected to two shielding doors at each end by two bidirectional spring hinges.

[0026] Preferably, both the front and rear clamps are made of metal.

[0027] Preferably, the microwave transmitter box is made of metal, the front cover of the microwave transmitter box is made of plastic, the bidirectional spring hinge of the shielding door is made of non-metallic material, and the shielding door is made of metal.

[0028] Preferably, the device further includes a solar panel and a panel support;

[0029] The solar panels are connected to the top plate of the casing via a panel support frame.

[0030] Preferably, each rotary moving component includes a horizontal moving mechanism and a rotating mechanism; the device also includes a motor drive module;

[0031] The horizontal moving mechanism includes a gantry frame and a No. 1 motor;

[0032] The gantry moving frame spans the top of the two gantry support frames; the control module drives the No. 1 motor through the motor drive module to move the gantry moving frame horizontally along the top of the gantry support frames; the top side wall of the rotating mechanism is connected to the side wall of the gantry moving frame, and the bottom of the rotating mechanism extends between the two gantry support frames;

[0033] The rotating mechanism includes a No. 2 motor, a motor mounting bracket, a coupling, a shield with columns, and a chassis with columns;

[0034] The motor mounting bracket has an L-shaped structure. The vertical end of the L-shaped structure is connected to the side wall of the gantry moving frame, and the horizontal end of the L-shaped structure is connected to the bottom of the housing of the No. 2 motor. The output shaft of the No. 2 motor passes through the horizontal end of the motor mounting bracket and is connected to one end of the coupling. The other end of the coupling is connected to the upper column with a column shield. The bottom surface of the column shield is connected to the upper column of the column chassis. Straw is placed between the shield on the column shield and the chassis on the column chassis.

[0035] Preferably, the device further includes a voltage conversion module, a relay module, a clock module, and a charge / discharge management module;

[0036] The control module is also used to control the solar panel to charge the battery through the charge and discharge management module. When the power monitoring module detects that the battery is fully charged, the charge and discharge management module controls the solar panel to stop charging the battery.

[0037] It is also used to cut off the charging of the solar panel to the battery through the charge and discharge management module, control the battery to discharge to the control module through the charge and discharge management module, and use the voltage conversion module to convert the DC power of the battery into AC power to discharge the microwave generator.

[0038] The motor drive module controls the second motor to rotate the straw for a preset time, while the clock module records the rotation time of the second motor. When the preset time is reached, the relay module cuts off the connection between the battery and the voltage conversion module, so that the battery stops supplying power to the microwave generator, and the motor drive module controls the second motor to stop working.

[0039] The beneficial effects of this invention are:

[0040] This invention uses a shell and gantry frame assembly as a support structure. Rotary moving components move horizontally on these components. When the straw is moved to the outside of the shell, it attracts adult armyworms to lay eggs. When the straw is moved inside the shell and directly in front of the microwave generator, microwave radiation kills the eggs on the straw. Furthermore, this invention uses a humidity sensor, a rain sensor, and a battery monitoring module for real-time detection. If the rain sensor detects rain, the humidity sensor detects humidity below a threshold, or the battery monitoring module detects that the battery level has reached a warning value, the two rotating moving components are immediately controlled to enter the shell and cease operation. Therefore, this invention has a high degree of automation.

[0041] Compared with the traditional method of manually using straw to attract eggs and then burning it, this device saves time and effort. In addition, this device can be recycled and requires no manual intervention after installation.

[0042] This device is equipped with two rotating and moving components, one inside the outer shell and the other outside the outer shell. After a preset number of days, their positions are exchanged. This arrangement ensures that eggs on the straw outside the outer shell will enter the inner shell after the preset number of days and be eliminated in time before hatching.

[0043] This device is designed based on the high selectivity of armyworms to their oviposition sites. Because this device can specifically kill armyworm eggs, it is more targeted than other devices and will not affect the reproduction of other beneficial insects.

[0044] This device uses solar energy to generate electricity and can work normally without an external power source. It does not use any chemical methods, does not consume any chemical reagents, and has no adverse effects on the external environment, making it very suitable for long-term fixed outdoor working environments.

[0045] This device uses microwave technology to effectively kill armyworm eggs, thereby reducing the growth rate of armyworm larvae in the vicinity of the device and preventing armyworm infestations from causing huge agricultural losses. Attached Figure Description

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0067] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0068] Example:

[0069] An egg-attracting and egg-destroying device for armyworms, the device includes a shell 1, a gantry assembly 2, two rotating and moving assemblies 3, a control module 7, a raindrop sensor 4, a humidity sensor 5, a microwave radiation device 6, a battery 21, and a power monitoring module;

[0070] The outer shell 1 covers the gantry assembly 2, and the two ends of the top beam of the gantry assembly 2 extend out of the outer shell; the two rotating and moving components 3 can rotate and carry the straw 13 placed on them to move horizontally along the top beam of the gantry assembly 2; the microwave radiation device 6 and the control module 7 are both set inside the outer shell 1;

[0071] The control module 7 is used to control one rotating moving component 3 to move to the outside of the outer shell 1, and at the same time control another rotating moving component 3 to move to the inside of the outer shell 1 and closer to the microwave radiation device 6. When the time since the last egg-killing reaches a preset number of days, the positions of the two rotating moving components 3 are swapped, and one rotating moving component 3 is controlled to move to the inside of the outer shell 1 and closer to the microwave radiation device 6, while the other rotating moving component 3 is controlled to move to the outside of the outer shell 1. It is also used to control the rotating moving component 3 located outside the outer shell 1 to move to the inside of the outer shell 1 when rain is detected by the raindrop sensor 4, humidity is detected to be below the threshold by the humidity sensor 5, or the battery 21 is detected to have reached the warning value by the power monitoring module.

[0072] The gantry assembly 2 is further defined below as including two gantry support frames;

[0073] The device also includes an outer shell support column 8, a short support column 9, a front clamping plate 10, a rear clamping plate 11, a heat dissipation channel 12, and an open shell 23;

[0074] Two gantry support frames are arranged in parallel, and two rotating and moving components 3 are located between the two gantry support frames. The bottom surface of the top beam of each gantry support frame is symmetrically connected to two short pillars 9. The top beam of the gantry support frame at the rear end is connected to the two connected short pillars 9, and the top beam of the gantry support frame at the front end is connected to the two connected short pillars 9, with a front clamping plate 10. The outer shell 1 covers the top beam, front clamping plate 10, rear clamping plate 11, and short pillars 9 of the gantry support frame. The columns at both ends of the gantry frame component 2 are exposed outside the outer shell 1. The outer shell support columns 8 are supported on the bottom plate of the outer shell 1, and the height after support is flush with the height of the columns of the gantry frame component 2.

[0075] A through hole is provided on the front clamping plate 10. The position of the through hole is opposite to the position of the microwave transmitting box 6-1 in the microwave radiation device 6. The back of the front clamping plate 10 is connected to the open shell 23. The open shell 23 is connected to the inner wall of the through hole of the front clamping plate 10, and the opening of the open shell 23 faces the through hole. A first heat dissipation hole 23-1 is provided on the rear shell of the open shell 23. A through hole 1-1 is provided on the front plate of the outer shell 1. The heat dissipation channel 12 passes through the through hole 1-1 to lead the heat discharged from the first heat dissipation hole 23-1 on the open shell 23 to the outside of the outer shell 1.

[0076] Specifically, the outer shell support columns provide effective support for the outer shell. The purpose of providing an open shell 23 is to create a sealed environment and minimize microwave leakage.

[0077] The composition of the microwave radiation device 6 is further defined below: The microwave radiation device 6 includes a microwave generator 6-4, a microwave transmitting box 6-1, a first microwave transmitting plate 6-2, and a second microwave transmitting plate 6-3.

[0078] The microwave generator 6-4 is mounted on the rear clamping plate 11 between the rear clamping plate 11 and the outer shell 1;

[0079] The microwave transmitter box 6-1 is mounted on the bottom plate of the outer shell 1 between the front clamping plate 10 and the rear clamping plate 11, and is positioned close to the rear clamping plate 11;

[0080] The first microwave transmitting plate 6-2 and the second microwave transmitting plate 6-3 are disposed inside the microwave transmitting box 6-1;

[0081] The microwaves generated by the microwave generator 6-4 are emitted to the straw 13 through the first microwave emitting plate 6-2 and the second microwave emitting plate 6-3. A second heat dissipation hole 1-2 is opened on the back plate of the outer shell 1 at the position corresponding to the microwave generator 6-4.

[0082] Specifically, the preset number of days is 3 days, because the armyworms or adult insects will hatch their eggs after 3 days, so the eggs on the straw 13 must be removed before the eggs hatch.

[0083] Because only one microwave generator is set in this embodiment, it can only kill the eggs on the straw on one rotating moving component. Therefore, only one rotating moving component can enter the shell to kill the eggs, while the other is set outside the shell to attract insects.

[0084] The microwave generator produces microwaves of a specific frequency and transmits them through a first microwave emitting plate and a second microwave emitting plate. Two microwave emitting plates are used primarily because the straw is relatively long, and two plates ensure effective radiation.

[0085] The core of this embodiment is microwave technology, which is similar to the implementation method of a microwave oven. When the frequency of microwaves is set within a certain frequency range, the molecular motion of water or fat in an object receiving microwave radiation will be consistent with the frequency of microwaves, resulting in a sharp increase in molecular oscillation speed and a corresponding rise in temperature, while other types of molecular motion will not be significantly affected.

[0086] The lure used to attract armyworms to lay eggs is dried straw. The eggs contain water and fat. When the straw containing the eggs is continuously exposed to microwave radiation, the temperature of the eggs rises rapidly and they are killed, while the temperature of the dried straw does not rise significantly.

[0087] The structure of the rotary moving component 3 is further defined below: each rotary moving component 3 includes a horizontal moving mechanism and a rotating mechanism 3-2; the device also includes a motor drive module;

[0088] The horizontal moving mechanism includes the gantry moving frame 3-1 and motor No. 1;

[0089] The gantry moving frame 3-1 spans the top of the two gantry support frames; the control module 7 drives the first motor through the motor drive module to move the gantry moving frame 3-1 horizontally along the top of the gantry support frame; the top side wall of the rotating mechanism 3-2 is connected to the side wall of the gantry moving frame 3-1, and the bottom of the rotating mechanism 3-2 extends between the two gantry support frames.

[0090] The rotating mechanism 3-2 includes a second motor 3-2-1, a motor mounting bracket 3-2-2, a coupling 3-2-3, a shield with a column 3-2-4, and a base with a column 3-2-5;

[0091] The motor mounting bracket 3-2-2 has an L-shaped structure. The vertical end of the L-shaped structure is connected to the side wall of the gantry moving frame 3-1, and the horizontal end of the L-shaped structure is connected to the bottom of the housing of the second motor 3-2-1. The output shaft of the second motor 3-2-1 passes through the horizontal end of the motor mounting bracket 3-2-2 and is connected to one end of the coupling 3-2-3. The other end of the coupling 3-2-3 is connected to the upper column of the column shield 3-2-4. The bottom surface of the column shield 3-2-4 is connected to the upper column of the column base 3-2-5. Straw 13 is placed between the shield on the column shield 3-2-4 and the base on the column base 3-2-5.

[0092] Specifically, the rotating mechanism is fixed to the gantry frame and moves horizontally with it. The motor drives the straw to rotate during microwave radiation, making the radiation more uniform. Flexible couplings should be used instead of rigid couplings to minimize damage to the shaft caused by the strong stress when the gantry frame moves the lower modules through the gate. The shielding cover, used to prevent microwave leakage during egg-killing, should be made of metal. To achieve better sealing, the radius of the circular portion of the column-mounted base is smaller than the radius of the circular portion of the shielding cover. The column-mounted base is made of rigid plastic. In this device, the column-mounted base serves as a platform for carrying the straw; the dried straw is tied to the circular portion of the base during use.

[0093] Further material specifications: both the front clamping plate 10 and the rear clamping plate 11 are made of metal. The body 6-1-2 of the microwave transmitting box 6-1 is made of metal, the front cover 6-1-1 of the microwave transmitting box 6-1 is made of plastic, the bidirectional spring hinge 18 of the shielding door 20 is made of non-metallic material, and the shielding door 20 is made of metal.

[0094] Specifically, both the front clamping plate 10 and the rear clamping plate 11 are made of metal. When the straw is microwaved, most of the heat and moisture will be dissipated through the heat dissipation channel. The second heat dissipation hole on the back of the outer casing is used to dissipate heat from the electronic components between the rear clamping plate 11 and the outer casing.

[0095] To ensure effective microwave radiation, the bottom shell of the microwave transmitter box is made of metal, while the cover is made of plastic. Two-way spring hinges allow all connected doors to open and close in both directions. Because the shielded door is exposed to microwave radiation, its two-way spring hinges must be made of non-metallic materials. The rainproof door prevents rainwater from being blown into the device by strong winds, while the shielded door provides a sealed environment for microwave radiation, preventing leakage; therefore, the shielded door must also be made of metal. Figure 11 The isolation plate 24 is used to isolate the microwave generator and the control module to prevent the strong electromagnetic radiation generated by the microwave generator from interfering with the control module.

[0096] The following further defines other structures: the device also includes two small rain shields 14 and two large rain shields 15;

[0097] One small rain cover 14 is provided on the front and rear surfaces of the outer casing 1. The two small rain covers 14 are used to cover the outlet of the heat dissipation channel 12 and the second heat dissipation hole 1-2 on the outer casing 1, respectively.

[0098] Two large rain covers 15 are connected to the two ends of the top plate of the outer shell 1 respectively, and the two large rain covers 15 cover the columns of the two gantry support frames inside.

[0099] Specifically, the main function of the outer casing, the large rain cover, and the small rain cover is to provide protection for the device from rain.

[0100] The device also includes a two-way spring hinge 18, a rainproof door 19, and a shielding door 20;

[0101] Two short pillars 9 on the same side are each connected to a rainproof door 19 on the opposite side wall. Each rainproof door 19 is connected to the short pillar 9 by a two-way spring hinge 18.

[0102] The front cover 6-1-1 of the microwave transmitter box 6-1 is connected to two shielding doors 20 at both ends by two bidirectional spring hinges 18. The back of the open shell 23 is connected to two shielding doors 20 at both ends by two bidirectional spring hinges 18.

[0103] The device also includes a solar panel 16 and a panel support 17;

[0104] The solar panel 16 is connected to the top plate of the outer casing 1 via the panel support 17.

[0105] The composition of this device is further defined below: the device also includes a voltage conversion module 22, a relay module, a clock module, and a charge / discharge management module;

[0106] The control module 7 is also used to control the solar panel 16 to charge the battery 21 through the charge and discharge management module. When the power monitoring module detects that the battery 21 is fully charged, the charge and discharge management module controls the solar panel 16 to stop charging the battery 21.

[0107] It is also used to cut off the charging of the solar panel 16 to the battery 21 through the charge and discharge management module, control the battery 21 to discharge to the control module 7 through the charge and discharge management module, and use the voltage conversion module 22 to convert the DC power of the battery 21 into AC power for the microwave generator 6-4 to discharge.

[0108] The motor drive module also controls the second motor 3-2-1 to rotate the straw 13 to a preset time. At the same time, the clock module records the rotation time of the second motor 3-2-1. When the preset time is reached, the relay module cuts off the connection between the battery 21 and the voltage conversion module 22, so that the battery 21 stops supplying power to the microwave generator 6-4. At the same time, the motor drive module controls the second motor 3-2-1 to stop working.

[0109] Specifically, the control module uses the STM32 series, the clock module uses the DS1302 clock module, and the charge / discharge management module uses the MPPT solar charge / discharge controller. The solar panel has a rated power of 100W, and the microwave generator contains two magnetrons, each with a rated power of 300W.

[0110] Working principle:

[0111] The two rotating and moving components have two position states when they are working, such as Figure 13 and Figure 14 As shown. When the two rotating moving components are working, the clock module built into the control module determines whether there are three days left since the last egg-killing. If three days have passed, the positions of the two rotating moving components are switched. When one rotating moving component moves into the housing 1 and approaches the microwave radiation device 6, the voltage conversion module converts the battery voltage into a suitable voltage to supply the microwave generator. The microwave generator emits microwaves of a specific frequency to the dried straw through the first and second microwave emitting plates. While the first and second microwave emitting plates are emitting microwaves, the control module drives the second motor through the motor drive module to rotate the dried straw and starts the clock module to start timing. After 5 minutes, the control module disconnects the battery and the input terminal of the voltage conversion module through the relay and stops driving the second motor. After the rotating microwave egg-killing is completed, the clock module records the date of the day for the next judgment. If less than three days have passed since the last egg-killing, it determines whether the gantry moving frame is in a dormant position. If so, the control module drives the gantry moving frame through the motor drive module to move to the previously stored standby position and then enters the... Figure 17 The energy storage state is shown; if not, proceed directly to the state shown. Figure 17 The energy storage state is shown. After the above process is completed, continue execution. Figure 18 The process shown determines whether three days have passed since the last egg removal.

[0112] The energy storage status is as follows: It determines whether the motor or microwave radiation device has started operating. If so, it initiates battery power supply: the charge / discharge management module controls the battery to supply power to the control module, enabling the control module to control the motor, or the relay module controls the battery to supply power to the microwave radiation device (the battery needs to convert DC to AC power through a voltage conversion module to supply power to the microwave generator). If not, it checks for sunlight. If there is no sunlight, it initiates battery power supply. If there is sunlight, the solar panel supplies power to the control module through the charge / discharge management module and charges the battery. When the power monitoring module detects that the battery is fully charged, it stops charging. Figure 17 As shown.

[0113] In standby mode, an interrupt condition is designed. When the interrupt condition is met, if a task is being executed in standby mode and the gantry is moving, the system must wait for the movement to complete before entering sleep mode; otherwise, the position value stored in the code will be corrupted. In other cases, the current task is stopped directly, and the system switches from standby to sleep mode. Figure 15 As shown. After stopping the current task, the current standby position value must be stored first; otherwise, the workflow in standby mode will be affected. In sleep mode, the control module uses its motor drive module to control the two gantry moving frames to move the dried straw evenly as shown. Figure 12 The fixed position shown is pre-written as a value into the control code. Afterwards, motors one and two, as well as the microwave generator, will not operate. The sleep state will cyclically check whether a series of conditions are met; only when all conditions are met will it switch from sleep state to standby state. Otherwise, the loop continues. Figure 16 As shown. Figure 16 Sufficient power in the system = 2 × (power required for one microwave egg sterilization + power required for switching between standby positions).

[0114] The following sections will describe these interruption conditions in turn:

[0115] Battery power below warning threshold: To prevent the battery from running out of power during operation, a warning threshold is set in the power monitoring module. When the battery power reaches this threshold, the system will automatically enter sleep mode. The warning threshold is calculated as 1.5 × (the amount of power required to return from standby to sleep mode).

[0116] Rain: In standby mode, heavy rain may wet the dry straw used to attract eggs, causing the straw to become moldy or its attractiveness to armyworms to decrease. Therefore, it enters a dormant state when it rains.

[0117] Humidity below 40%: When humidity is below 40%, the armyworm's reproductive capacity decreases and the eggs cannot hatch. At this time, the threat of the armyworm is reduced, and it can enter a dormant state to store energy.
