Embodiment 1

[0028] An indoor phase-controlled electronic sound focusing method for driving away and killing flying insects, comprising the following steps:

[0029] Step 1) The array acoustic transducer receives the acoustic signal sent by the vibration of the wings of flying insects, and each acoustic transducer at different positions in the array acoustic transducer receives different delayed acoustic signals, and converts the delayed acoustic signals into electrical signal;

[0030] Step 2) delivering the electrical signal to the FPGA chip through the signal acquisition and processing device for processing;

[0031] Step 3) The FPGA chip obtains the frequency, amplitude, time delay and spatial position and direction of the sound source by analyzing the electrical signal, and performs automatic identification and classification of insects;

[0032] Step 4) The signal generation circuit controlled by the FPGA chip generates a control acoustic emission excitation source corresponding to ...

Abstract

The invention discloses an indoor phase control electronic sound focus type flying insect expelling and killing method and device. The device comprises a plurality of acoustic transducers which are combined into an array acoustic transducer. The array acoustic transducer is connected with a signal acquisition and processing device, an FPGA chip, a rotation and movement control device and a drive power supply. The array acoustic transducer is connected with the FPGA chip through a signal generation circuit. The FPGA chip is connected with the signal acquisition and processing device. The method includes the steps of receiving signals of wing vibration of flying insects, conducting positioning, and transmitting sound signals to expel or kill flying insects. The sound signals of wing vibration of flying insects are received through the array acoustic transducer, high-speed positioning, identification and signal frequency obtaining are conducted, sound field energy of the specific frequency is converged in the designated area and a high-intensity sound field is generated by controlling transmission excitation of the acoustic transducers through an FPGA, and flying insects in the focus area are expelled or killed according to the principle that a mechanical effect is generated after the high-intensity sound field acts on flying insects.

Description

technical field [0001] The invention belongs to the field of sound control. Specifically, the invention relates to an indoor phase-controlled electronic sound-focusing type flying insect repelling and killing method and device. Background technique [0002] Indoor flying insects such as flies, mosquitoes, flying ants, cockroaches, etc. affect people's daily life and pollute the surrounding environment. They themselves carry all kinds of germs and are one of the important ways for virus transmission. Great harm to human life and health. The killing methods that people often use in daily life are mainly chemical methods, such as insecticides, electric mosquito coils, etc. These methods also pollute the environment when killing insects, and improper use or long-term use will also harm the human body. cause harm. Secondly, physical control methods are adopted, such as trapping and killing with lights, hanging mosquito nets, etc. These methods are a kind of passive defense and...
