VIBRATION ENERGY DETECTION APPARATUS AND VIBRATION ENERGY DETECTION SYSTEM

WIPO Patent Application WO/2013/153845

A1

A vibration energy detection apparatus comprises: a vibration power generation device that is disposed in a test object to convert vibration energy generated in the test object into power; a power storage unit that stores the power generated by the vibration power generation device; a voltage monitoring unit that monitors the storage voltage in the power storage unit; a discharge control unit that discharges the energy stored by the power storage unit when the storage voltage of the power storage unit exceeds a predetermined storage voltage; and a vibration energy calculation unit that calculates the vibration energy generated in the test object on the basis of the number of power storage states of the power storage unit which are formed continuously or intermittently by the discharge by the discharge control unit. In this manner, a vibration energy detection apparatus or system that is capable of accurately detecting the vibration energy generated in the test object by using the vibration power generation device can be provided.
