| Abstract: | On the basis of the study of track vibration,a monitoring system is completed based on USB2. 0 interface. The system, with 891-2 vibration pickup as vibration sensor, LPC1768 as central control chip, USB serial interface bus as the transport channel of data, realizes the acquisition of track surface vibration signal,analysis of time domain, frequency domain and function of real-time display. After testing,the sys- tem performance is stable and the result is in line with expectation. It is suitable for monitoring of construc- tion site with good practicality and usability. |
