Example Embodiment

[0025] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but it is not intended to limit the protection scope of the present application.

[0026] The high-speed train noise self-driven power generation noise measurement and data transmission method of the present invention, the steps of the method are:

[0027] The first step is to collect statistics on the noise spectrum of important observation points along the high-speed train in the early stage, and determine the main spectrum range to which the noise of each observation point belongs; obtain the resonator array that can collect the noise of the main spectrum range of the corresponding observation point; and then The resonator arrays are installed at the corresponding important observation points, and are arranged on both sides of the high-speed train, as close as possible to the high-speed rail line without affecting the operation of the vehicle and the st...

Abstract

The invention relates to a high-speed train noise self-driven power generation noise measurement and data transmission method and a high-speed train noise self-driven power generation noise measurement and data transmission device. The method and the device utilize an acousto-electric conversion unit to convert energy contained in noise along a high-speed rail into electric energy, supply power for a sound level meter and drive the sound level meter to complete data measurement of noise, combine with an Internet of Things transmission technology to achieve the collection of noise data, complete the self-driven noise measurement and remote data transmission near the high-speed rail, generate a real-time noise map near the high-speed rail through the collection, collation and analysis of data, and provide a guidance basis for the traffic development planning and noise pollution control measures of China. The method and the device can effectively reduce the noise in the environment, further can turn the noise pollution into resources and effectively utilize the resources, and conform to the current development concept of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of noise power generation system, noise measurement near high-speed rail lines, and remote signal transmission based on the Internet of Things, in particular to a method and device for high-speed train noise self-driven power generation noise measurement and data transmission. Background technique [0002] China's high-speed rail industry has achieved rapid development in the past 10 years, and the "Fuxing" high-speed rail EMU has achieved a speed of 350 kilometers per hour. Since the aerodynamic noise increases with the vehicle speed (v) roughly at the rate of 60lgv to 80lgv, when the vehicle speed is greater than 200km / h, the aerodynamic noise will become an important noise source (Kitagawa T, NagakuraK.Aerodynamic noise generated by Shinkansen ears[J ].Journal of Sound and Vibration, 2000, 23(3):913-924); when the vehicle speed is further increased, the aerodynamic noise dominates the high-speed rail nois...
