Machine vibration energy recovery system based on piezoelectric effect

The utility model belongs to the field of electronic information and specifically relates to a machine vibration energy recovery system based on a piezoelectric effect. The system includes an energy conversion module, a charge collection module, an electrical-energy storage module, a single-chip microcomputer, a display module and an alarm module. The energy conversion module, the charge collection module, the electrical-energy storage module and the single-chip microcomputer are connected in order. The display module and the alarm module are connected with the single-chip microcomputer respectively. The machine vibration energy recovery system based on the piezoelectric effect is capable of recovering and storing, which cannot be used originally, of device vibration, so that energy consumption cost of a factory is reduced in a great degree. The energy recovered by the system can be widely reused for factory illuminating devices or living facilitates and the like so that energy waste is reduced. The system is
