Research on the Application of Noise Monitoring System Along Railway Tracks Based on Real-Time Data Acquisition and Processing

In order to solve the problem of whether the environmental noise along the railway exceeds the standard, a noise monitoring system along the railway has been designed that can achieve the integration of noise data acquisition, A/D conversion, Ethernet transmission, algorithm processing, data storage, and interface monitoring. The system uses ADS1256, TMS320VC5509, and ADR4525 chips to complete system signal conditioning, signal conversion, and signal processing, and completes data network transmission to the OneNet cloud through the Ethernet module W5500. The upper computer of the system uses VS.NET and C# to achieve cloud data reading, and the lower computer implements DPS data processing through the CCS6 environment and C program. The system test shows that the data acquisition accuracy is 0.2 level, and the maximum frequency division vibration level and Z vibration level values are used as noise research and judgment indicators to meet the system monitoring purpose.
