Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1As shown, the device of the present invention includes a frame, a signal detection system and a signal playback system. The signal detection system and the signal playback system are independent. Except for the signal acquisition card, the other components of the signal detection system are located inside the frame; the signal replay system is located inside the frame. The signal detection system and the signal playback system are respectively fixed on brackets on both sides of the base in the frame.

[0030] Such as figure 1 and figure 2 As shown, the frame includes a front panel 1 , a rear panel 2 , a left panel 3 , a right panel 4 , an upper panel 5 , a first support 6 , a second support 7 , a base 8 and a silicone bottom plate 9 . The front panel 1 is the same size as the rear panel 2, and the left panel 3 is th...

Abstract

The invention relates to a detector for a vibration signal of an insect. The detector is composed of a frame, a signal detection system and a signal playback system, a signal collection card of the signal detection system is arranged outside the frame, residual part of the signal detection system and the signal playback system are respectively fixed on supports at the two sides of a pedestal in the frame. A radome is arranged outside the frame, and interference of air disturbance on the vibration signal is shielded. Silica gel is bonded to the bottom of the frame. In the signal detection system, sound emitted by the insect is transferred to a sensor via a host plant, the sensor converts vibration of the plant into a corresponding electric signal, the electric signal is transmitted to a preamplifier via an electromagnetic shielding wire, and the preamplifier amplifies and outputs the electric signal. In the signal playback system, recorded chirp of the insect is transmitted to vibration converters in the upper and lower layers via the electromagnetic shielding wire, and diaphragm of the vibration converters transmit the vibration signal to the host plant via hard metal wires.

Description

technical field [0001] The invention relates to a detection device for insect vibration signals. Background technique [0002] Acoustic signal is the link between the life activities of insects and the external environment, and plays an important role in calling, courting, attacking and alarming among individuals within a species. The acoustic signal of insects is divided into two types, one is the sound transmitted directly by air (air-borne sound), and the other is the weak vibration signal (substrate-borne vibration) transmitted by the medium, and the latter signal requires the help of sensitive instruments to be detected. Through the analysis and processing of the collected insect vibration signals, the understanding of insect acoustic signals can be deepened, and the foundation for the replay of insect vibration signals can be laid. [0003] The replay technology of insect vibration signals is based on the detection technology of insect vibration signals. After the co...
