The tilt angle detection using the piezoelectricity acceleration sensor

피에조 가속도 센서를 이용한 기울기 각도 검출

It is necessary to detect the tilt angle for control or monitoring of various systems such as ship, aircraft recreation facilities etc as well as bridge or building systems. However the electronic liquid charge type tilt sensor which is one of typical tilt sensor has many problems. Those are remarkably slow response time and limited mounting condition because or liquid viscosity coefficient and inertia etc. In this study we propose a tilt angle instrumentation method using piezoelectricity acceleration sensor. The method can he applied on moving mount We verified the validity of the method through experiment.
