PURPOSE: A hybrid type power supply device for a multi smart gateway is provided to continuously supply power by applying environmentally friendly energy harvesting technology. CONSTITUTION: A gateway(10) is constructed for a USN(Ubiquitous Sensor Network) system. A photovoltaic power generation module(30) generates power from solar energy. An energy harvesting module(40) generates power from wind, water, and vibration energy. A charging module(20) receives power from the energy harvesting module and the photovoltaic power generation module and supplies charged power to the gateway. |
