Abstract

The invention discloses an energy collection device based on piezoelectric power generation and a control system and a control method thereof. The energy collection device comprises a power generation device, an energy conversion module, and a storage device. The power generation device comprises a cover plate, an impact block, fixed columns, a piezoelectric dual-chip array, a base plate, and a wire. The energy conversion module is connected with the storage device through a doubling rectifier circuit. The storage device is connected in parallel with a voltage regulator diode through a super capacitor. The invention provides an efficient energy collection device, and automatic energy collection is realized through a control system.

Description

technical field [0001] The invention relates to an energy collection device, in particular to a high-efficiency energy collection device based on the principle of piezoelectric power generation, a control system and a control method. Background technique [0002] Collect one or more of the heat energy, wind energy, sound energy, who can, solar energy, mechanical energy and human activity energy in the surrounding environment and convert them into electrical energy, and then directly supply power to electronic devices or store them in capacitors, rechargeable In devices such as batteries, this process is known as energy harvesting. There are many ways to collect energy from various energy sources, such as electromagnetic induction, static electricity, radio frequency radiation and piezoelectric effect, etc. Mechanical vibration is a form that is ubiquitous in the environment. The principle of vibration energy collection is to use the displacement of the sensor Or mechanical ...
