specific Embodiment approach 1

[0046] A device for detecting the boreholes of tree trunks, such as figure 1 , figure 2 and image 3 As shown, it includes an elastic band, a PCB control module, an antenna, a housing and a power supply; the PCB control module is arranged in the housing, and the housing and the elastic band are detachably connected through an elastic band interface, and the elastic band is provided with an antenna The interface is fixedly connected to the antenna through the antenna interface. There are several antennas, and no less than 2 antennas. In this embodiment, 16 antennas are used. The antenna is connected to the PCB control module, and the power supply supplies power to the PCB control module. The PCB control module includes a PC control platform communication interface circuit, a PC-controller timing control interface circuit, a local oscillator interface circuit, a band-pass filter circuit, a power supply interface circuit, a transmitting signal amplifying circuit two, transmitti...

specific Embodiment approach 2

[0062] The detection method realized based on a kind of detection device for trunk internal borer pests, comprises the following steps:

[0063] Step a, put the elastic band on the trunk to be detected;

[0064] Step b, connecting several antennas to corresponding antenna interfaces on the elastic band;

[0065] Step c. Connect the PCB control module to power supplies of different voltage levels;

[0066] Step d, set the corresponding frequency through the PCB control module, and modulate to generate the required synchronous pulse signal. The signal is transmitted through the antenna and transmitted to the tree trunk according to the serial number of the antenna. The signal is scattered at the interface of different dielectric constant media , thus forming an echo signal;

[0067] Step e, obtaining corresponding acquisition signals through the receiving antenna in turn;

[0068] Step f. All the collected signal data is connected to the computer through the PCB control modul...

Abstract

The invention provides a device and a method for detecting a moth passage of trunk moths in a trunk, and belongs to the field of tree detection. The invention provides an automatic device and method for detecting the moth passage of trunk moths in the trunk, which is diversified in measurement data, small in error, high in accuracy, good in imaging effect, portable and lightweight, and wide in adaptability. In the device provided by the invention, a PCB control module is disposed in a shell, the shell is detachably connected with an elastic band through an elastic band interface, the elastic band is provided with an antenna interface and is fixedly connected with an antenna through the antenna interface, the antenna is connected with the PCB control module, and a power source supplies power to the PCB control module; the elastic band is sleeved on the trunk; corresponding frequency is set by the PCB control module, and modulation is performed to generate a required synchronization pulse signal and is transmitted to the trunk according to an antenna serial number sequence to form an echo signal; the signal collected by the antenna is received; and a computer is connected to completethe imaging of the moth passage of the trunk moths in the trunk. The device and the method provided by the invention are mainly used for detecting the moth passages in trees.

Description

technical field [0001] The invention belongs to the field of tree detection, and in particular relates to a detection device and a detection method for trunk borers and insects. Background technique [0002] With the development of society and economy, the natural environment began to deteriorate continuously, and various kinds of stem borers multiplied and spread in large numbers, causing damage to trees by eating bark and xylem. When the insect population density is high and the damaged parts are connected to form girdling It can lead to the death of trees that are several years old to more than ten years old in a short period of time, and the spread spreads rapidly, which brings serious losses to the development of my country's forestry economy. In order to detect the damage of tree borers, many detection technologies have appeared. Generally speaking, there are: anatomical observation method, radar wave detection technology, laser detection technology, infrared detection ...
