Self-consistent driving sensor, functional device and electric excitation method for realizing driving sensing

Abstract

The invention provides a self-consistent driving sensor, a functional device and an electric excitation method for realizing driving sensing. The self-consistent driving sensor comprises a supporting shell, an electric excitation assembly, a driving body and a sensor, the electric excitation assembly and a magnetostriction body are both installed on the supporting shell, and the electric excitation assembly is arranged in the circumferential direction of the magnetostriction body or is connected with the end of the driving body. When the electric excitation assembly applies first electric excitation, the driving body can be driven to generate first deformation, so that the sensor can generate a first induction signal. When the electric excitation assembly applies second electric excitation, the driving body can be driven to generate second deformation, so that the sensor can generate a second induction signal. The first induction signal is used for calibrating a reference value of the target detection quantity, the second induction signal is used for obtaining the measurement value of the target detection quantity, and then the variable quantity of the target detection quantity can be obtained. According to the present invention, the driving sensor can sense during driving, and is simple in structure and high in measurement precision.
