VIBRATION DETECTION DEVICE, AIR PRESSURE DETECTION TERMINAL, AND ACCELERATION DETECTION SYSTEM

WIPO Patent Application WO/2011/118693

A1

Provided is a vibration detection device wherein it is possible to store the power generated by the device itself and to reduce the size of the device. Also provided are an acceleration detection system and an air pressure detection terminal using said vibration detection device. A vibration detection terminal (2) is provided with a vibration power generator (4) which generates AC voltage by vibrating, a DC-AC conversion circuit (9) which converts the AC voltage generated by means of the vibration power generator (4) into DC voltage, a power storage element (10) which stores power by means of the converted DC voltage, and a counter circuit (7) which counts the number of vibrations of the AC voltage generated by means of the vibration power generator (4). The number of vibrations counted by means of the counter circuit (7) during a predetermined time period is sent to a vibration detection controller (3) as acceleration calculating data. The power storage element (10) supplies power to each constitutional element of the vibration detection terminal (2).
