TECHNICAL FIELD
[0001] The application belongs to the field of soil disease prevention and control, and particularly relates to a crawler-type inter-row operation microwave soil disease prevention and control device and method. BACKGROUND
[0002] Disinfecting the soil before planting crops is an important means of preventing and controlling diseases, pests and weeds, and traditional methods of preventing and controlling soil diseases of crops include chemical sterilization, steam sterilization and sunlight sterilization.
[0003] Chemical sterilization and disinfection can easily cause soil and air pollution, which is very harmful to the human body, and the prevention and control of crop soil diseases, pests and weeds mainly relies on high-toxicity and high-residue pesticides, which has caused problems such as pesticide resistance, pest resurgence, pesticide residue and environmental pollution, and destruction of biodiversity.
[0004] Deep ploughing and exposure, steam sterilization and other soil disease prevention and control measures are mostly taken before planting crops, and sunlight interference has seasonal and regional limitations; at the same time, steam sterilization equipment is complex and not suitable for large-area soil disinfection; and both prevention and control measures have great limitations and cannot cope with possible soil diseases during the whole growth cycle of crops.
[0005] In addition, biological control has the advantage of not polluting the environment, but also has certain limitations, such as narrow insecticidal range, difficulty in mass production of products, and limitations on storage and transportation.
[0006] Microwave sterilization is a method of killing pathogens in soil by using the thermal effect and non-thermal effect of microwaves, and microwaves can penetrate soil and their energy is converted into heat energy after being absorbed by pathogens, resulting in denaturation of pathogen proteins and loss of biological activity.
[0007] Patent CN202222302036.8 discloses a microwave prevention and control device for bacterial diseases in soil, which uses a soil sampling baffle to sample and stack soil, and uses microwaves to sterilize and disinfect the soil. The patent needs to shovel the soil into the equipment for sterilization and then transport it back to the ground, which is not suitable for soil where crops have been planted.
[0008] Patent CN201310543551.8 discloses a soil sterilization and insecticidal equipment and a method for killing root-knot nematodes using the equipment, which needs to be used for rough plowing of the soil to be killed before use, stirring the soil by a soil lifting device and lifting it upward, high-temperature roasting the soil in the process of lifting by a quartz tube, microwave sterilization by a microwave emitting device after falling to the ground, and finally flattening the soil by a soil supporting plate. The patent is also only suitable for soil disinfection treatment before cultivation and is not suitable for soil with planted crops. In addition, the patent uses a chain track type remote control tractor, which can avoid microwave radiation or high-temperature damage to the human body when the human body is close by using remote control. However, the staff cannot accurately monitor the surrounding environment of the sterilization equipment and cannot judge the soil state. In the process of equipment operation, the staff completely relies on remote control of the working route, microwave frequency and other process parameters, which has poor flexibility and is prone to errors and repeated work in the actual operation process.
[0009] In summary, how to kill pests, weeds and diseases in the soil in an environmentally friendly, non-toxic and non-residual manner, disinfect the soil in the case of planting crops in the soil, and more accurately control the energy of the equipment to improve the automatic working performance of the equipment and facilitate the operation personnel to improve the work efficiency are problems urgently to be solved in the field of soil disease prevention and control.

[0065] S2: The track walking mechanism 1 of the device drives the track walking mechanism 1 to advance on the working path according to the preset speed, the preset driving speed of the track walking mechanism is 20 m / min, the panoramic camera 9 and the laser radar 10 are started to assist in high-precision positioning and topographic mapping, and the device works accurately along the preset path, monitors the surrounding environment, automatically adjusts the path according to the obstacle terrain, feeds back the distance between the device and the two sides of the ridge to the central control system 5, adjusts the position and angle of the microwave antenna, the preset microwave power reaches 20000W, the microwave frequency reaches 915MHz, and the physical condition of the ridge surface is fed back to the central control system 5. When there are soil blocks and weeds on the ridge surface that affect the microwave antenna, the central control system 5 controls the crushing device 13 to crush the target position on the surface of the ridge, and when there are protrusions on the surface of the ridge that affect the operation of the microwave antenna, the central control system 5 drives the flattening roller 14 to flatten the target position;
[0066] S3: During the microwave sterilization process, the infrared imager 11 monitors the temperature of the soil surface and weed surface and feeds the data back to the central control system 5. When the device is stationary, the soil temperature measuring device 12 turns its opening toward the soil ridges on both sides in sequence. The soil bimetallic thermometer 122 extends and is inserted into the soil ridges to measure the temperature at different depths of the soil. The measured temperature data is fed back to the central control system 5. The microwave frequency and heating time of the microwave sterilization are adjusted according to the preset temperature threshold. If the temperature meets the target temperature, the set parameters are reasonable and the operation continues. If the temperature does not meet the target temperature, the process parameters are automatically adjusted according to the built-in deep learning algorithm until the target temperature is met and the operation continues. This ensures that the soil temperature is kept within the temperature threshold range during the operation. The microwave sterilization temperature for the soil surface and weeds reaches 85°C, and the microwave sterilization temperature for the soil interior is 55°C.

In addition to automatically adjusting the process route and parameters through the central control system 5, staff can also actively adjust them on the remote electronic device 16.
