Embodiment 1

[0034] Such as figure 1 As shown, this embodiment proposes a self-driven high-precision angle measurement system, which includes an angle sensor 100 , a multi-channel synchronous data acquisition module 200 , a microprocessor module 300 , a communication module 400 and a mobile terminal 500 .

[0035] This embodiment utilizes the triboelectric charge generated during the rubbing process between metal copper and Kapton (polyimide) film and the spatial position change of the electrostatically induced charge to realize the direct sensing of the rotational motion: two planes that are in contact with each other during the rubbing process Due to the difference in their ability to obtain electrons, they will be charged with frictional charges of equal magnitude and different sign. When one of the planes is rotated relative to the other plane, the spatial position of the frictional charges will also change accordingly, which will lead to positive and negative electrodes. The amount of...

Embodiment 2

[0053] Corresponding to Embodiment 1 above, this embodiment proposes a self-driven high-precision angle measurement method, such as Figure 5 As shown, the method includes:

[0054] S500. Using at least two sets of frictional nanogenerators to generate friction through rotational driving of the rotating member to be tested to generate alternating current signals respectively, and there is a phase difference between the alternating current signals generated by the frictional nanogenerators.

[0055] S510, synchronously collect the generated AC signal, and transmit it to the microprocessor module 300 for processing and calculation.

Abstract

The embodiment of the invention discloses a self-driving high-precision angle measuring system and method. The system comprises an angle sensor component, a multi-channel synchronous data acquisitionmodule and a microprocessor module. Based on the frictional electrification effect, a frictional nanogenerator is used to directly convert rotary motion into an alternating current signal for output.The output signal exhibits ideal signal-to-noise ratio. By analyzing the generated alternating current signal, real-time and accurate measurement of rotation angle and rotation direction is realized.The overall system has a simple and compact structure, is easy to integrate with the spindle of a variety of devices, and has the advantages of self-driving work and wide application range.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of nano-new energy and self-driven sensing, and in particular to a self-driven high-precision angle measurement system and method. Background technique [0002] Among the existing angle measurement devices, the basic working principles can be mainly divided into photoelectric type, electromagnetic type and inertial measurement unit type. However, these angle measurement methods cannot directly convert the angle data into electrical signal output, resulting in the transmission and amplification of errors. At the same time, these sensor devices often require complex signal amplification circuits to achieve reliable angle measurement, which limits the miniaturization and portability of the device. In addition, the above-mentioned angle sensor devices need to be powered by the outside world when they work, which cannot meet the needs of the development of the robot field and the era of the ...
