摘　　要：随着人类能源需求的不断增大,太阳能和风能等环境能量作为新的能量来源成为近年来研究的热点。面对环境能量中占有很大比例的振动能量,本研究设计了一种基于压电陶瓷的路面振动能量收集系统。该系统将压电片以一定的方式组成压电片阵列,将压电片阵列埋于道路下面,结合收集电路,用以收集行驶车辆的振动能量。该系统在收集振动能量的同时,通过实时分析能量收集情况,还能够识别出通过能量收集区的车辆类型。With the increasing human demand for energy,environmental energy such as solar and wind power as a new source of energy has become a hot research topic in recent years.Given the fact that vibration energy is a large part of the environmental energy,a vibration energy harvesting system based on piezoelectric ceramics is designed in this study.The system uses many piezoelectric chips in a specific way to form a piezoelectric array.The piezoelectric array is buried under the road and is combined with the collection circuit to collect the vibration energy of the driving vehicle.By analyzing the real time data of harvesting energy,the system can identify the passing vehicle types while collecting vibration energy.
