High-speed railway external noise automatic monitoring device

Abstract

The invention relates to a high-speed railway external noise automatic monitoring device, and belongs to the technical field of high-speed railway environmental noise monitoring. The high-speed railway external noise automatic monitoring device comprises a data collecting storage module, a meteorological monitoring module, a train passing signal trigger module, a data comprehensive analysis module, a data transmission module and a power supply module; the data collecting storage module is connected with the data comprehensive analysis module, the meteorological monitoring module is connected with the data comprehensive analysis module, the train passing signal trigger module is connected with the data comprehensive analysis module, the data transmission module is connected with the data comprehensive analysis module, and the data collecting storage module, the meteorological monitoring module, the train passing signal trigger module and the data comprehensive analysis module are connected with the power supply module correspondingly. According to the high-speed railway external noise automatic monitoring device, in an unattended situation, high-speed railway environmental noise andtrain operation radiating noise are automatically monitored, and the on-site monitoring situation can be grasped in real-time through wireless network.

Description

technical field [0001] The invention relates to an automatic monitoring device for noise outside a high-speed railway vehicle, which belongs to the technical field of environmental protection, in particular to the technical field of high-speed railway environmental noise monitoring. Background technique [0002] By the end of 2018, the operating mileage of my country's high-speed railways had reached more than 29,000 kilometers. While the high-speed railway brings great convenience to people's travel, it also has a great impact on the living environment of residents along the line. Keeping track of the noise status of high-speed railways and the noise patterns of each time period will help guide the railway department to rationally adjust traffic flow and reduce noise disturbance to the public. [0003] At present, my country's monitoring of the noise outside the high-speed railway is mainly based on mobile monitoring. Each test requires on-site installation of test equipme...

AI Technical Summary

Problems solved by technology

[0003] At present, my country's monitoring of the noise outside the high-speed railway is mainly based on mobile monitoring. Each test requires on-site installation of test equipment, which is cumbersome and inefficient, and the noise level measured is the noise level on the day of the test, which cannot truly reflect the acoustic environment during non-test periods. quality

[0004] At present, there is no long-term application of equipment, methods and application cases for automatic monitoring of noise outside high-speed railway vehicles, and only some demonstration applications in the field of automatic monitoring of urban noise
