Description

Technical Field

[0001] The present invention relates to the technical field of insect ethology, and particularly to a device for measuring the wing beat frequency of flying insects. Background Art

[0002] The research on the signals generated by the wing beat frequency (wing-beats) of insects can be traced back to 1939. In a series of subsequent experiments, researchers found that the wing beat frequencies are different among different species of insects and between different genders of the same species. It can be used as an important basis for insect classification or detecting their occurrence status, or as one of the characteristics to study the actual influence of other variables on insect behavior. Currently, the detection methods for insect wing beat behavior mainly rely on microphones, stroboscopes, photoelectric sensors or high-speed cameras, each having problems such as insufficient accuracy, too short detection distance, and high cost. At the same time, most of the acquisitions of insect wing beats are carried out under the condition of fixing the insects, and the wing beat frequency of the restrained insects will change compared with the natural situation. In addition, the method of fixing insects often uses adhesives to bond the towing rope or fixing rod to the insect trunk, and this process often causes poisoning to the insects or irreversible damage to their bodies.

[0003] Therefore, how to provide a device for measuring the wing beat frequency of flying insects has become an urgent technical problem for those skilled in the art. Summary of the Invention

[0004] In view of the above situation, the object of the present invention is to provide a device that can measure the wing beat frequency of insects through multiple acquisition paths without restraining the insects, so as to solve the problems that existing devices are difficult to collect the wing beat frequency of freely flying insects and it is difficult to balance the acquisition accuracy and cost.

[0005] To achieve the above object, the present invention provides a device for measuring the wing beat frequency of flying insects, including: a top cover and a bottom plate, as well as two long side plates and two short side plates. The above components are jointly combined to form a semi-closed space for the test insects to move or fix the test insects; wherein four slide rails are installed on both the top cover and the bottom plate for fixing and adjusting the position of the short side plates; at the geometric centers of the top cover, the bottom plate, the long side plates and the short side plates, there are detachably replaceable component boards for measuring the wing beat frequency of flying insects.

[0006] Furthermore, grooves are provided at the geometric centers of the top cover, the bottom plate, the long side plates and the short side plates. The shape of the grooves is square, and the size matches that of the component boards; the component boards are placed in the grooves and fixed by connectors.

[0007] Furthermore, the component boards are divided into three categories according to different mounted devices: infrared / green / blue-violet light transmitting board, microphone array board, infrared / green / blue-violet light receiver array board.

[0008] Furthermore, when the infrared / green / blue-violet light emitting panel emits infrared light, the wavelength of the infrared light emitted is between 900nm-1000nm; when it emits green light, the wavelength of the green light emitted is between 492nm-580nm; when it emits blue-violet light, the wavelength of the blue-violet light emitted is between 390nm-492nm.

[0009] Furthermore, the microphone array board and the infrared / green / blue-violet light receiver array board are connected to the signal processing device via signal lines.

[0010] Furthermore, the infrared / green / blue-violet light emitting board can emit pulsed light at a certain frequency, and the frequency is adjusted by adjustable components on the infrared / green / blue-violet light emitting board, or directly input by the host computer.

[0011] Furthermore, the infrared / green / blue-violet light emitting board is equipped with an independent power supply, or is powered by a host computer.

[0012] Furthermore, the long side panels are connected to the top cover and the bottom panel by means of tenons, and are reinforced by means of L-shaped clamps at the far ends of the connection positions.

[0013] Furthermore, the specific form of the slide rail is: a narrow and long slot is opened on the inner side of both ends of each long side of the plate, and a fixing clip for fixing the short side plate is installed in the narrow and long slot. The fixing clip can slide freely in the narrow and long slot and can be fixed in the narrow and long slot by a gasket and a nut.

[0014] Furthermore, four fixing clips are fixedly mounted on each short side panel by screws, and rubber covers are arranged at the edges of the short side panels connected with the top cover, the bottom panel and the long side panels.

[0015] The beneficial effects of the present invention are:

[0016] The present invention proposes a collection device that can measure the wing beat frequency of insects through multiple collection paths without restraining the insects, so as to solve the problem that existing equipment is difficult to collect the wing beat frequency of free-flying insects and difficult to balance the collection accuracy and cost; and the components carried by the component board can be replaced in a targeted manner according to different experimental purposes, which is not only convenient to replace but also greatly improves the wide applicability of the device.

The components carried on the component board 6 can be replaced in a targeted manner according to different experimental purposes.

[0040] To further optimize the technical solution, grooves are provided at the geometric centers of the top cover 1, the bottom plate 2, the long side plates 3 and the short side plates 4. The grooves are square in shape and the size matches that of the component board 6. The component board 6 is placed in the grooves and fixed by connectors. The component board 6 can be fixed by magnetic strips / slidable magnetic stickers, which are used for test insects that are clearly not disturbed by magnetic substances and thus affect the experimental results. The top cover 1 and the bottom plate 2 have the same structure. Length scales with millimeters as the minimum unit are engraved on the two long sides of the plate, and the midpoint of the long side is the origin of the scale, that is, the zero point.

[0041] To further optimize the technical solution, the component board 6 can be replaced according to the experimental purpose and the size of the test insect. The component board 6 is divided into three categories according to the different devices carried: infrared / green / blue-violet light transmitting board 8, microphone array board 9, infrared / green / blue-violet light receiver array board 10.

The fixing clips 7 can slide freely in the narrow empty slots and can be fixed in the narrow empty slots (excluding the installation place of the fixing clips) by gaskets and nuts.

[0053] Further optimize the technical solution. Four fixing clips 7 are fixedly installed on each short side plate 4 by screws, and rubber seals are provided at the edges of the short side plate 4 connected to the top cover 1, the bottom plate 2, and the long side plate 3.

[0054] Further optimize the technical solution. The materials of the top cover 1, the bottom plate 2, the two long side plates 3, and the two short side plates 4 are transparent or milky white acrylic plates.

[0055] The present invention proposes a collection device that can measure the wing beat frequency of insects through multiple collection paths without restraining the insects, so as to solve the problem that existing equipment is difficult to collect the wing beat frequency of free-flying insects and difficult to balance the collection accuracy and cost; and the components carried by the component board can be replaced in a targeted manner according to different experimental purposes, which is not only convenient to replace but also greatly improves the wide applicability of the device.

[0056] The method of use of the present invention is:

[0057] (1) Before starting the experiment, assemble all components, adjust the spacing between the short side panels according to the size and type of insects to be detected, and replace the appropriate component boards.

[0058] The assembly methods of each component are as follows:

[0059] ⅠWill Figures 6-11 The fixing clips shown are mounted on the short side panels and secured with screws and nuts, as shown Figure 4 As shown;

[0060] Ⅱ Combine and roughly fix the two long side panels through anti-skid pads and knurled nuts / butterfly nuts;

[0061] Ⅲ Put the top cover and bottom plate through Figure 13 The slot structure shown is fixed to the long side panel, and the effect after completion is Figure 14 ;

[0062] IV. Figure 15 The clips shown are installed at the octagonal parts of the device to enhance the structural strength.

[0063] Ⅴ Remove each component board and install the component board corresponding to the experimental purpose.

[0064] Ⅵ Before the experiment begins, adjust the positions of the two short side panels according to the experimental requirements and locate them according to the scales on the top cover and bottom plate. After determining the position, tighten the knurled nut / butterfly nut on the fixing clamp to fix the position of the plate.

[0065] (2) If the experimental insect needs to measure the wing beat frequency while being restrained, remove the component board on the top cover or bottom plate to allow the rod or wire used to fix the insect to pass through; adjust the position of the experimental box so that the insect is within the detection range of the component board sensor.

[0066] (3) At this time, power is turned on, and the transmitter will generate pulsed light of a certain frequency (preferably, this frequency is set to 50 MHz) as a carrier under the drive of an internal / external clock signal. When the insect is flying, the pulsed light will irradiate on the wings of the insect and produce reflection. When the wings of the insect are transparent, part of the light may pass through the wings of the insect and produce refraction. The reflected and refracted light is received by the receiver to generate an electrical signal, and then this signal will be transmitted to the signal processing module for filtering and demodulation. At the same time, the microphone array board will continuously pick up the audio signal generated by the wing vibration of the insect.

[0067] (4) If it is necessary to measure the wing vibration frequency of the experimental insect in free flight, the insect can be directly placed into the box, all the cover plates are covered, and then the measurement can be started.

[0068] (5) When the live insect crawls on the bottom plate, due to the height at which the light transmitter and the receiver are located, the insect will not block the light emitted by the transmitter. Only when the insect flies and crosses the detection range of the sensor, will the receiver receive the wing vibration signal. At the same time, the microphone will continuously collect the sounds generated by the activities of the insect for comparison and reference to obtain more real data.

[0069] Further, the materials of the top plate and the long side plates used can be replaced with aluminum alloy, which can further increase the structural strength and isolate external electromagnetic wave interference (such as 50 Hz power frequency interference).

[0070] Further, in order to induce the insect to fly, a small cage with an open bottom can be covered at the opening of the top cover, and food can be suspended inside the cage.

[0071] Example 1:

[0072] Measure the wing vibration frequency of Protaetia brevitarsis Lewis under the condition of being restricted. A copper rod is glued to the pronotum of the test insect, and the component board on the top cover is removed. The copper rod penetrates in, so that the position of the flower chafer is within the detection range of the sensor. At this time, the component boards installed on the two short side plates are the infrared light emission board and the infrared light detector board respectively; the component board on the long side plate is the microphone array board and the component board installed with a temperature and humidity sensor. Power is turned on. When the flower chafer flaps its wings, the temperature and humidity data and the wing vibration audio recorded by the microphone will be transmitted to the host computer for storage and processing; and the infrared light transmitter will emit infrared light pulses of a certain frequency. After the pulses are blocked by the flying insect, they will be scattered / refracted into the infrared light receiver to generate an electrical signal. This signal will be filtered and demodulated by the signal processing board connected to the infrared light detector board and conducted to the host computer for processing after analog-to-digital conversion.

[0073] Example 2:

[0074] Measure the wing vibration frequency of Protaetia brevitarsis Lewis under free movement conditions. Remove the component board on the top cover, cover the empty slot with a bottomless cage, and hang beetle jelly in the cage to induce the beetles to take off. Before the experiment starts, put the beetles into the box through the empty slot on the top cover, and then cover the empty slot with the cage hanging the food. At this time, the component boards installed on the two short side plates are the infrared light emitting board and the infrared light detector board respectively; the component board on the long side plate is the microphone array board and the component board installed with the temperature and humidity sensor. Turn on the power. When the flower chafer takes off and passes through the detection area, the temperature and humidity data and the wing vibration audio recorded by the microphone will be transmitted to the host computer for storage and processing; the infrared light emitter will emit infrared light pulses at a certain frequency. After the pulses are blocked by the flying insects, they will be scattered / refracted into the infrared light receiver to generate an electrical signal. This signal will be filtered and demodulated by the signal processing board connected to the infrared light detector board, and then conducted to the host computer for processing through analog-to-digital conversion.

[0075] As described above, it is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
