摘要
为了解决铁轨沿线环境噪声是否超标的问题,设计了能够实现噪声数据采集、A/D转换、以太网传输、算法处理、数据存储和界面监控一体化的铁轨沿线噪声监测系统。该系统采用ADS1256、TMS320VC5509和ADR4525芯片完成了系统信号调理、信号转换和信号处理,通过以太网模块W5500完成了数据网络传输至OneNet云端。系统上位机采用VS.NET和C#实现了云端数据读取,下位机通过CCS6环境和C程序实现了DPS数据处理。系统测试表明,数据采集精度为0.2级,利用分频最大振级和Z振级数值作为噪音研判指标,满足了系统监测目的。
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.
