Description

Technical Field

[0001] The present invention relates to the technical field of intelligent prevention and control of agricultural pests, and in particular to a monitoring, trapping and killing device, method and system for fruit fly pests in the field. Background Art

[0002] Fruit fly pests (such as the citrus fruit fly and the melon fruit fly) are increasingly harmful to the fruit and vegetable industry. In the existing technology, the power grid trapping device uses a continuous high-voltage electricity mode. Although it can achieve insect body knockdown, there is a problem of carbonization of the insect body adhering to the electrode (experimental data show that the false capture rate is greater than 40%), and the high-voltage circuit has a potential safety hazard in the field; although the image recognition monitoring system can achieve insect species classification, the recognition accuracy drops sharply in strong light overexposure or low-light scenes at night (the literature indicates that the misjudgment rate is greater than 35%), and the equipment power consumption is as high as 15W, which is difficult to adapt to the field environment without mains power supply. In terms of trapping materials, traditional food attractants have the defect of unstable volatilization rate: when the ambient temperature rises from 20°C to 35°C, the volatilization rate of methyl eugenol fluctuates by 63%, resulting in a dramatic change in the trapping effect with temperature.

[0003] In view of this, we propose a monitoring and trapping device, method and system for fruit fly pests in the field to solve the existing problems. Summary of the invention

When the environmental sensor detects that the relative humidity is greater than 85%, it automatically increases the pulse frequency to above 3Hz to prevent condensation on the electrodes.

[0010] Furthermore, the communication module includes a SIM card slot and APN automatic configuration protocol, supporting seamless switching of the three major operators' networks; it also includes a signal strength threshold control unit, which enables the CAT-M1 low-power mode when the 4G signal is greater than -100dBm, otherwise switches to the LoRa self-organizing network mode.

[0011] Furthermore, the differential filtering algorithm of the infrared counter executes the following logic: when the 850nm channel detects a signal with a body length of 2-5mm, and the 940nm channel collects a wing beat frequency of 80-120Hz, it is determined to be a fruit fly pest; if the difference rate between the two channel data is greater than 15%, the signal error correction mechanism is triggered.
