Embodiment Construction

[0033] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0034] Such as figure 1 As shown, the present invention is a flying robot for long-distance sound signal acquisition, including a quadcopter. The quadcopter includes a central body 1, four sets of support arms 2, four sets of propellers 3 and four pairs of brushless coaxial motors. Four pairs of brushless coaxial motors 4 are connected to the central body 1 through support arms 2, four sets of propellers 3 are respectively arranged on the four pairs of brushless coaxial motors 4, four sets of support arms 2 are evenly distributed around the central body 1, and are located same plane.

[0035] In this embodiment, the central body is divided into three layers of space in the order from top to bottom, wherei...

Abstract

The invention discloses a flying robot for remote sound signal acquisition. The flying robot comprises a four-axis aircraft and a remote ground station. A waveform acquisition layer, a flight control layer and an image acquisition layer are arranged on a center aircraft body of the four-axis aircraft, a partition plate 1, a rotary platform, a connecting platform 1 and a laser remote sound acquisition device are arranged on the waveform acquisition layer, the laser remote sound acquisition device is composed of a laser transmitting device and a laser receiving device, and the laser transmitting device is connected with the rotary platform through the connecting platform 1. The image acquisition layer is formed by a connecting platform 2 and a high-accuracy infrared camera, the flight control layer and the remote ground station are combined for remote control, the waveform acquisition layer and the remote ground station are combined for remote sound acquisition, and the image acquisition layer and the remote ground station are combined for navigation and auxiliary adjustment. By the utilization of the remote wireless control technology and the laser remote sound acquisition device and through the cooperation of the high-accuracy infrared camera and a GPS positioning system, a target position is accurately positioned, the laser remote sound acquisition device can be moved to a position where target sound is remotely captured, remote sound acquisition under remote control is achieved, the safety of personnel is improved, and the integrity of a scene is kept.

Description

technical field [0001] The invention relates to the fields of optics and acoustics, in particular to a flying robot based on a quadcopter for long-distance sound signal acquisition. Background technique [0002] Acoustic signal is an important object of one-dimensional signal research, and long-distance acoustic signal acquisition technology has a very wide range of applications due to its non-proximity characteristics, and is an important branch of acoustic research. For example, in natural science research, the sound recording of various animals in the wild; the study of biological dynamic sound; In occasions such as live recording of vocal music, it is required that the recorder should not appear in the image to enhance the sense of presence. Therefore, the research on long-distance sound acquisition is very necessary. [0003] There are currently very few ways to acquire sound from a distance, and there are many limiting factors. The currently widely used me...
