Problems solved by technology

However, the three-dimensional spatial distribution of noise in a mountainous environment is more complicated. Due to the unevenness of the ground, the distance from the aerial measurement point to the ground is likely to exceed 100 meters, so it is impossible to use the method of erecting a bracket for noise collection.

Embodiment 1

[0077] A noise collection system carried by a tethered balloon is characterized in that it includes a tethered balloon group 1, a wired noise collection device 2, a total station spatial positioning system 3, and a ground power supply and signal collection system 4.

[0078] The tethered balloon group 1 is composed of N identical tethered balloons, and the tethered ropes of the balloon group are tied into a node, according to image 3 Make the top of the balloon group on the same horizontal plane, thereby reducing the windward area in all directions as much as possible, and ensuring the reliability of the lift provided by the balloon, so as to reduce the impact of individual balloons on the entire system due to air leakage.

[0079] The wired noise collecting device 2 includes a beacon light 2-1, a sound collecting instrument 2-2, a universal prism 2-3, a lightweight bracket 2-4 and a cable 2-5. The top of the lightweight bracket 2-4 is fixedly connected to the bottom of the main sh...

Embodiment 2

[0101] A noise collection system carried by a tethered balloon is characterized in that it includes a tethered balloon group 1, a wireless noise collection device 2, a total station spatial positioning system 3, and a ground power supply and signal collection system 4.

[0102] The tethered balloon group 1 is composed of N identical tethered balloons, and the tethered ropes of the balloon group are tied into a node so that the top of the balloon group is on the same horizontal plane, so as to minimize the windward area in all directions and ensure The balloon provides the reliability of lift to reduce the impact of individual balloons on the entire system due to air leakage.

[0103] The wireless noise collection device 2 includes a beacon light 2-1, a sound collection instrument 2-2, a universal prism 2-3, a lightweight bracket 2-4, a battery 2-5, a wireless signal module 2-6 and a cable 2 -7. The top of the lightweight bracket 2-4 is fixedly connected with the bottom of the main...

Abstract

The invention discloses an air noise acquisition system taking a captive balloon as a carrying platform. The system can acquire noises at any points in the low-altitude range about 200m away from the ground. The system includes four parts, namely, a captive balloon set, a noise acquisition device, a total station space positioning system, and a ground power supply and signal acquisition system. The air noise acquisition device is connected with three ground fixed points through three light mooring cables, the captive balloon set provides lifting force for the air noise acquisition device, and the air measuring points are accurately positioned by means of a total station. A wired communication or wireless communication manner is selected based on the height of the air measuring points to transmit the acquired data back. Electrical leads are wound on the mooring cables to provide the power supply and wired communication transmission functions for the noise acquisition device.

Description

Technical field [0001] The invention relates to a noise collection device, in particular to an aerial noise collection system using a tethered balloon as a carrying platform. Background technique [0002] With the development of urban road systems and the rapid increase of traffic vehicles, the gradual increase in urban noise has caused great disturbance to people's lives, seriously affected the quality of life of urban residents, and caused many social problems at the same time. Therefore, urban noise is increasing. The more people pay attention. [0003] The sources of urban traffic noise present diverse and complex characteristics. In addition to the common motor vehicle noise, rail transit in my country has also become an important source of urban traffic noise in recent years. Because rail transit vehicles will generate large wheel-rail noise and structural vibration noise at the same time when passing through a specific rail bridge, their noise level is high and spread far,...
