Abstract

The invention discloses a traffic load pavement vibration energy piezoelectric power generation measuring method and a system thereof. The traffic load pavement vibration energy piezoelectric power generation measuring system comprises a piezoelectric transduction unit, a total control module and a total measuring module which are arranged on a pavement. The piezoelectric transduction unit is used for converting pavement vibration energy into electric energy. The total control module is used for regulating speed and applying load for running vehicles and regulating electric parameters for output electric power. The total measuring module is used for measuring speed and load of a vehicle, stress and deformation of the pavement, harvested alternating-current and voltage, and transduced voltage and current. The generated electric energy can be used as a power supply to be stored and utilized. According to above condition, the traffic load pavement vibration energy piezoelectric power generation measuring system provides conditions for researching a mechanism of a pavement piezoelectric energy harvesting technology, application and popularization of the technology, and has a high academic value and social value.

Description

Technical field [0001] The invention relates to the field of environmental energy capture, in particular to a method and a system for measuring vibration energy of a road surface under a driving load. Background technique [0002] With the continuous improvement of energy efficiency and environmental cleanliness and protection requirements, the development of environmentally friendly and pollution-free new energy sources has increasingly become one of the hot topics. Driving vehicles inevitably bring pressure and impact to the road surface, causing strain and stress in both the vertical and horizontal directions of the road surface. The energy generated will not only produce vibration and noise, but seriously affect the life of the road surface and the surrounding environment. In order to recycle this part of energy, some systems and methods have been developed. Among them, the piezoelectric power generation device developed by the positive piezoelectric effect of piezoelectric ...
