INTRODUCTION
In the national defense and military affairs, the detection of passing vehicles in a specific area is of great significance for understanding each other’s dynamics. The monitoring of bridge vibration can be more convenient to monitor vehicle dynamics. Considering the concealment, destructiveness and inconvenience of construction, this terminal uses wireless communication, battery power supply and micro-power design. Common wireless communication methods include Bluetooth

The field of smart structures and smart materials has been an emerging area of research for last few decades. A smart structure would be able to sense the vibration and generate a controlled actuation to it, so the vibration can be minimized. For this purpose, smart materials are used as actuators and sensors. In this paper, some literature review is given about smart structure and smart material. Piezoelectric material is used as smart material and cantilever beam is considered as a smart

For the nonlinear vibration signal of stayed cables, a new particle filter algorithm is used in this paper. Firstly, nonlinear dynamic model of the stayed-cable and beam coupling system is dispersed in temporal dimension by using the finite difference method. So the discrete nonlinear vibration equation of any cable element is gotten. And secondly, a state equation of particle filter is fitted by least square algorithm from the discrete nonlinear vibration equation. So the particle filter
