- 摘要：The dynamic strain and vibration acceleration are two key parameters in the monitoring of vibrations that can damage track and affect the safety of railway traffic. This paper presents a remote measurement system for the online monitoring of train-induced vibration responses in rail tracks. A precision data acquisition node is designed for the conditioning and monitoring of the vibration signals generated by trains traveling at full speed. The monitored data is remotely acquired using a wireless sensor network. Furthermore, the use of solar power significantly increases the long-term service life of the system. The system is validated using both laboratory tests and a field deployment over a period of several months on an in-service high-speed railway. The obtained results indicate that the remote measurement system can accurately collect dynamic strain and vibration acceleration signals in a rail; these signals can be processed and analyzed to allow timely maintenance actions.
