The invention discloses a people stream treading pressure and noise energy collecting device, which comprises an energy input unit, an energy storage unit and an energy output control unit, wherein anLTC-3588 energy collection module is adopted to collect weak energy and output the weak energy to an electric energy storage unit, and electric energy generated by a piezoelectric ceramic piece is fully collected; the electric energy in a super capacitor is fully utilized by adopting an automatic buck-boost module; an MSP430 main control chip is adopted, and the energy loss can be greatly reduceddue to the low power consumption mode when the system is in a non-working state; in a man-machine interaction system composed of a display screen and keys, various detection data in the display screen is adjusted through the keys according to different external environments, the output power consumption of the whole system can be reduced while complete functions are achieved, and the purpose of saving energy is achieved. The beneficial effects of the invention are that the circuit design and module selection of each unit are carried out, and the electric energy output power consumption is reduced under the condition of guaranteeing that the whole system can achieve the complete functions.
Description
technical field [0001] The invention belongs to a piezoelectric principle energy collection device system, in particular to a device that utilizes a novel piezoelectric ceramic sheet to generate electricity and alleviates electricity consumption in public places through various loss-reducing electric energy technologies. Background technique [0002] According to the current situation of world development, due to the shortage of resources caused by population pressure, especially in the future, human beings will have to face the problem of depletion of natural energy resources, so technicians engaged in the energy field have been looking for a non-renewable resource that can replace natural mineral energy. renewable energy, such as: research and development of more efficient and environmentally friendly solar panels, wind power generation, tidal power generation, exploration of feasible ways of controllable nuclear fusion...etc. At present, piezoelectric ceramic sheets have ...
