Abstract

The invention relates to the RF identification field, and discloses a rotary encoder two-phase signal processing circuit and a signal processing method thereof. The rotary encoder two-phase signal processing circuit comprises a signal conversion unit, a pulse generating unit and a triggering unit. The input end of the signal conversion unit is used as the input end of the two-phase signal processing circuit. The output of the triggering unit is used as the output end of the two-phase signal processing circuit. The signal conversion unit processes a two-phase signal and outputs serial data. The pulse generating unit processes the serial data and outputs a pulse signal. The triggering unit latches the pulse signal and outputs a rotary pulse output signal, wherein the signal conversion unit comprises a gate circuit. The pulse generating unit comprises a trigger. The triggering unit comprises a trigger. By means of a simple circuit unit, the two-phase signal which is output from the rotary encoder can be processed to a stable and independent pulse signal so that structure of a two-phase signal processing circuit of the rotary encoder is simplified and the cost is reduced.

Description

[0001] This application is a divisional case with the application number 2014101882979, the application date is May 6, 2014, the applicant is Shengbo Technology (Shanghai) Co., Ltd., and the invention name is a rotary encoder two-phase signal processing circuit and its signal processing method Apply. technical field [0002] The invention relates to the field of signal processing, in particular to the technology of two-phase signal processing of a rotary encoder. Background technique [0003] A rotary encoder is an electromechanical device that converts a rotary position or quantity into an analog or digital signal. It is generally installed on the side of the vertical rotation axis in the rotating object. Rotary encoders are used in many occasions that require precise rotational position and speed, such as industrial control, robotics, special lenses, computer input devices (such as mice and trackballs), etc. The dual-output rotary encoder outputs two sets of A / B pulses w...
