| Abstract: | Distributed optical fiber vibration sensing technology and fiber-optic vibration signal pattern recognition technology are proposed and analysed. The vibration signal is detected in accordance with the theory of M-Z interference, and the position of the signal is determined by the two-way time delay technology. Different mathematical methods are used to analyse the optical fiber vibration signals, and the character of vibration signal generated by different events information is found. Then, MATLAB is employed for simulation analysis. The characteristic parameters of excavators, moving vehicles and personnel movement could be found through the analysis of the simulation system to distinguish the three different types of events. |
