Design of Data Acquisition System Based on C/S Structure for High-Speed Railways Earthquake Early Warning
摘要
Abstract
24-bit data acquisition system is designed based on C/S structure for High-speed Railways earthquake early warning,the hardware of system contains control board and detachable data acquisition board. Control board is com-posed of STM32F407 microcontroller,SD memory card and Ethernet interface,the main function of control board con-tains data sampling control,storage and transmission;data acquisition board is composed of FPGA control board and 6-ch 24-bit sampling card,which functions include data sampling,packing and transmission. The C/S structure software is achieved by transplanting LwIP in server,implementing network function by LabVIEW in client,which function in-clude remote parameter setting and data waveform display. The test result shows that:the acquisition system channel consistency is good,and the SNR is better than 140dB on the condition of 200 sample/s sampling rate.关键词
