Multi-turn absolute encoder, encoding method, controller and storage medium

Abstract

The invention relates to the technical field of rotary encoders, and provides a multi-turn absolute encoder, an encoding method, a controller and a storage medium. The encoder consists of a rotary shaft, control board, magnet, Hall sensors, controller, master controller, single-turn absolute encoder, and non-volatile memory. One side of the control circuit board is vertically provided with the rotation shaft; the magnet is fixedly connected with the rotation shaft; the Hall sensor is set at the position corresponding to the magnet on the other side of the control circuit board, which is used to collect the information of the number of turns of the rotation shaft after power failure; the control The encoder is used to collect the data of the Hall sensor after power-off; the single-turn absolute value encoder is set on one side of the control circuit board at the position below the magnet, and is used to collect the relative position information of the rotating shaft after power-on; the main controller Calculate the absolute position information of the rotary axis. The embodiment of the present invention has simple structure, small volume and easy integration.

Description

technical field [0001] The invention relates to the technical field of rotary encoders, in particular to a multi-turn absolute encoder, an encoding method, a controller and a storage medium. Background technique [0002] A rotary encoder, also known as a shaft encoder, is an electromechanical device that converts a rotational position or amount of rotation into an analog or digital signal. It is generally installed on the side of a rotating object that is vertical to the axis of rotation. Rotary encoders are suitable for occasions that require precise measurement of rotational position and speed, such as industrial control, robotics, special lenses, computer input devices (such as mice and trackballs), etc. [0003] Rotary encoders include absolute encoders and incremental encoders. Absolute encoders are further divided into single-turn absolute encoders and multi-turn absolute encoders. [0004] When the system is powered off, the multi-turn absolute encoder can still mai...
