Abstract

The invention relates to the technical field of sensors, and discloses a triboelectric rotation sensor and a monitoring system. The triboelectric rotation sensor comprises a rotating shaft, a stator assembly, a rotor assembly, a shell assembly, a variable-amplitude rotor electrode set and a variable-amplitude stator electrode set. The rotating shaft is rotationally installed on the shell assembly, the stator assembly is fixed to the shell assembly, and the rotor assembly is fixed to the rotating shaft. The variable-amplitude stator electrode set is arranged on the stator assembly, the variable-amplitude rotor electrode set is arranged on the rotor assembly, and the friction film covers variable-amplitude rotor electrodes and is in contact with the variable-amplitude stator electrodes. When the rotor assembly rotates along a first direction relative to the stator assembly, the amplitude-variable rotor electrode and the amplitude-variable stator electrode are coupled to output an electric signal with a first rule. When the rotor assembly rotates in the second direction relative to the stator assembly, the variable-amplitude rotor electrode and the variable-amplitude stator electrode are coupled to output an electric signal with a second rule. The triboelectric rotation sensor can monitor the rotating speed, the rotating angle and the direction of the rotating shaft.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a triboelectric rotation sensor and a monitoring system. Background technique [0002] Sensor technology is one of the three pillars of modern information technology. It is widely used in industrial automation, automotive electronics and communication technology. It has become an indispensable standard for measuring the development of scientific research and industrial manufacturing. Among various mechanical motions, rotary motion is one of the most basic forms in the field of industrial automation, and has always been a research hotspot in the field of scientific and engineering applications. The traditional rotational motion sensing technology mainly includes photoelectric conversion, electromagnetic induction, and electric effect. However, with the continuous improvement of industrial automation level and manufacturing requirements, passive sensor technology with self-powered ...
