The catching system comprises a box body, an air limiter, a catching net, a fan and a plastic hollow pipe; the inlet of the box body is connected with a vertical plastic hollow pipe, and the plastic hollow pipe is positioned in the box body; the air limiter, the catching net and the fan are arranged in the plastic hollow pipe from top to bottom; the wind limiter is in a funnel shape for weakening wind speed; the catching system and the shading recognition counting system are connected through another plastic hollow pipe.
The attracting system comprises an insect trapping UV lamp and a drug tray; the insect trapping UV lamp is positioned at an inlet of the scattering recognition counting system, and the medicine tray containing the attractant is positioned in the box body.

The working process of the field insect monitoring instrument is as follows:
the insect trapping UV lamp and the chemical attractant-containing drug tray attract nearby flying insects to the upper part of a field insect monitoring instrument, and the weak suction force of the internal fan can suck the insects into the two identification and counting systems from the uppermost plastic hollow tube. Due to the limitation of the wind limiter, the wind speed in the detection areas of the two recognition and counting systems is not enough to enable the insects to lose the capability of wing vibration, but the insects still can fly downwards and sequentially pass through the scattering recognition and counting system and the shading recognition and counting system, and finally reach the mosquito catching net through the round hole in the center of the wind limiter.
Near infrared light emitted by a light source with a certain divergence angle in the scattering recognition counting system can be collimated into parallel light beams by a collimating lens, and a detection area with uniform light intensity is formed under the plastic hollow tube at the top. When the insects descend from the channel of the plastic hollow pipe to the detection area of the scattering identification and counting system, the vertical downward scattering detector detects a corresponding scattering light intensity signal due to light scattering caused by flapping of the bodies and wings of the insects. The scattered signals not only retain the scattered light signals of the insect body but also retain the scattered light signals of wing vibration after passing through the direct current signal amplifier, and are finally collected and processed by the signal collecting processor. The scattered signals of the body and the wings of the insect can be used as the basis for identifying the insect, the insect species can be identified according to the body size of the insect, the identification can be carried out according to the vibration frequency of the wings, and the identification accuracy is improved.
Near infrared light rays emitted by a light source with a divergence angle in the shading recognition counting system are collimated by the light source collimating lens group, and the light rays are converged on a detector of the shading system by the light focusing lens group again after being uniformly transmitted for a certain distance. Thus, a detection area with uniform light intensity is formed under the plastic hollow pipe. When no insect passes through the detection area, the light intensity received by the detector is kept unchanged all the time and cannot be amplified by the alternating current signal amplifier. When the insects continuously fly downwards through the scattering identification counting system and pass through the shading detection area, the light intensity detected by the shading detector is uniformly changed due to the shading of the vibration of the insect body and the wings to the light, the light intensity is amplified by the alternating current signal amplifier and finally collected and processed by the signal collection processor. The shading identification counting system can identify the insects according to the periodic frequency of the wing vibration of the insects.
Because the wind speed below the shading recognition counting system is large, insects can reach the mosquito catching net through the round hole in the center of the wind limiter after passing through the shading recognition counting system. Below the wind limiter, the fan with the maximum wind speed can firmly suck the insects in the catching net because of no limitation of the wind limiter. In addition, because the structure of the wind limiter is similar to a funnel shape, insects are difficult to pop out the catching net from the round hole of the wind limiter, and the functions of attracting, identifying, counting and catching the insects are realized.
The two identification and counting systems are used for collecting and processing detected insect signals by the signal collection processor and then reach the terminal processing display through the wireless transmission system, so that the function of on-line monitoring of field insects is realized. FIG. 8 is a scattered light signal of the body and wing vibration of the insect recorded by the scattering identification counting system, and the scattered light signal is obviously increased on the basis of background light. This is because the scattered light caused by the insect body has a large intensity and therefore has a significant convex signal based on the background light, and at the same time, the vibration of the insect wing causes a scattered light signal with a higher frequency, and the wing vibration signal is superimposed on the scattered light signal of the body. Fig. 9 is a signal of light intensity change caused by insect wing vibration recorded by the shading recognition counting system, and the light signal of periodic change is recorded by the detector due to periodic light shading caused by periodic vibration of the insect wing in the detection area. The insect signals recorded in the two recognition and counting systems are respectively subjected to Fourier transform in the information acquisition and processing system, the vibration frequency of the insect wings is analyzed, and the intensity of scattered light signals triggered by the insect body is combined, so that the aim of recognizing the insects is fulfilled.
In the open-air insect monitoring instrument of this embodiment, use two kinds of discernment count systems in combination, the insect is successively through two kinds of discernment count systems of scattering and shading, according to the time delay of detecting the signal between two systems, judges whether the insect is caught by the system to improve the count degree of accuracy of insect. If the insects are only recorded by the scattering identification counting system and not counted by the shading identification counting system, the insects do not fly downwards continuously, but fly upwards to escape the monitoring instrument. If the insects are recorded by the scattering recognition counting system, the insects are recorded by the shading recognition counting system after a period of time, and the insects are shown to fly downwards all the time and are finally captured. Of course, the method can also analyze whether the insects belong to the same insect according to the wing vibration frequency of the insects, so that the accuracy of identification and counting is greatly improved.
According to the embodiment of the invention, the identification counting system for field insect online monitoring can be combined with an optical identification technology, an insect attraction technology and an insect capture technology to form a new monitoring system, so that the accuracy of insect identification can be greatly improved, the accuracy of insect counting can also be improved, and the characteristics of portability and low cost can make the system suitable for field insect monitoring application.
