Description

An intelligent trapping quantity recorder of Monochamus alternatus

technical field

The invention relates to a trapping number recorder for Monochamus alternatus used by impact traps.

Background technique

The pine monochamus belongs to the Coleopteridae family and mainly harms the genus Pinus. It is a serious borer pest in forestry. It often uses larvae to harm the phloem and xylem of weakly growing pine trees or newly felled logs, seriously affecting the growth of pine trees, and even Caused large areas of pine trees to die.

The reason why Monochamus alternatus has attracted people's serious attention is that it is the main vector of pine wood nematode disease. The adults of Monochamus alternatus that carry pine wood nematode feed on the bark of young shoots of healthy pine trees to supplement nutrition. The pine xylophilus nematode infects healthy pine trees through bark wounds caused by gnawing, and then rapidly reproduces in large numbers in healthy pine trees, which can quickly cause pine trees to weaken and die.

In order to protect pine forest resources, relevant forestry departments conduct trapping, monitoring, and prevention and control of the population dynamics of the Monochamus alternatus every year. This process consumes a lot of manpower, material and financial resources.

Therefore, using such an instrument that can remotely record the time and quantity of Monochamus alternatus trapping, the trapping method can be used to timely and accurately understand the activity patterns of Monochamus alternatus adults 24 hours a day and at various times throughout the year, saving a lot of time for trapping It is of great significance to prevent and control Monochamus alternatus in time. So as to achieve the purpose of protecting forest resources on the basis of saving human and financial resources.

Contents of the invention

The technical problem to be solved by the present invention is: combine the impact type Monochamus alternatus trap with ① waterproof microphonic pickup and radio transmission system (comprising miniature microphonic pickup and wireless transmission module) and ② radio wave receiving system, ③ acoustic Pattern recognition system and ④intelligent data collection system (including personal computer (PC) and corresponding software) are organically combined to record the number and time distribution of Monochamus alternatus trapped by the monochamus trap in real time, which is more beneficial Keep abreast of the activity rules of Monochamus alternatus adults, and reduce the high cost of laborious manual investigations.

The technical solution used by the present invention to solve the above technical problems is: the monochamus alternatus flies to the trap under the attraction of the attractant, hits the cross plate of the trap and falls into the longicorn collecting bottle below the trap, and the longicorn beetle hits the trap. The sound of the cross plate and the bottom of the bottle is sensed and collected by the high-sensitivity waterproof micro-acoustic pickup, and the audio signal is converted into an electrical signal and sent to the waterproof wireless transmission module, and then transmitted to the remote computer terminal after being processed by the wireless transmission module , after the radio wave receiving system in the computer receives the signal, it will transmit the signal to the voiceprint recognition system, and the voiceprint recognition system will combine the voiceprint information such as the amplitude and frequency of the received sound with the pre-stored Comparing the sound of the plate and the bottom of the bottle, after confirming the match, the intelligent data collection system will record the time and quantity of the longhorn beetle captured. The time distribution of the number of cattle caught by traps, and the analysis of the activity of Monochamus monochamus adults in 24 hours a day and at various times throughout the year.

The above-mentioned impact-type longchapter trap is a monochamus trap widely used in forests at present.

The above-mentioned waterproof microphonic pickup is used to collect the sound of the longicorn falling into the bottle. Since the sound of the longicorn falling into the bottle is relatively weak and short, it is necessary to use a high-sensitivity microphonic pickup to monitor the sound of the longicorn falling into the bottle, and The voiceprint information such as the amplitude and frequency of this sound is sent to the wireless transmitting module in the form of an electric signal, so as to transmit this signal to the PC of the monitoring personnel.

The above-mentioned wireless transmitter module with waterproof function is a miniature or small transmitter module, because the space in the collection bottle is limited, and the space occupied by too many technical instruments will affect the storage of more longhorns in the collection bottle.

The above-mentioned PC is equipped with a radio wave receiving software. After receiving the trapping information of long-distance long-distance long-distance beetles, it will combine the voiceprint information such as the amplitude and frequency of the received sound with the pre-stored sound information of the long-distance long-beetle colliding with the cross baffle and the bottle. After comparing the sound at the bottom, after confirming the match, it will automatically record the time and quantity of trapping beetles, and automatically draw the time distribution map of the daily trapping quantity, the distribution map of the daily trapping quantity every month, and the time distribution map of the year. The distribution pattern of the number of traps every 10 days.

By modulating the frequency band or feature code of the wireless transmitting module and the radio receiving software on the PC, the identification of different hanging locations and different traps can be realized, and the trapping data of different traps at different locations can be independently recorded and summarized.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Implementation method: see figure, 1. Songmo longicorn beetle impact type trap 2. Acquisition hole of microphonic pickup 3. Waterproof miniature microphonic pickup 4. Waterproof miniature wireless transmitting module 5. Connected with radio receiving software, Songmo The PC of the beetle impact voiceprint recognition software and trapping data summary function software

The specific method of use of the present invention is: hang the pine nut trap in the pine forest that needs to be protected, turn on the switch of the microphonic pickup and the wireless transmission module, provide energy through the battery power supply, and the high-sensitivity microphonic pickup will automatically run, When the beetle attracted by the attractant falls into the beetle bottle, the sound from the impact will be collected in time, and the audio signal will be converted into an electrical signal and sent to the wireless transmission module, which will send the sound signal in the form of radio waves It is sent to the remote computer terminal, and finally the time and quantity of longhorn beetles are captured can be recorded.

The invention can obtain the time and quantity of Monochamus alternatus trapped by the trap within the range of about 5000m.

in conclusion

Up to now, there is no relevant report on the trapping number recorder of Monochamus alternatus in China. The present invention proposes for the first time a waterproof microphonic pickup and a radio transmission system (comprising a waterproof miniature microphonic pickup and a wireless transmission module), a radio wave A trapping quantity recorder of Monochamus alternatus organically combining main components such as a receiving system, a voiceprint recognition system and an intelligent data collection system (including a personal computer (PC) and corresponding software).
