Abstract

A composite multifunctional encoder is composed of axle chain, composite encode disk, reading head system, processing circuit and casing, and is characterized by that is can output N groups of M-bit absolute encoded signals (where N is greater than 2 and M is greater than 4) and one group of incremental encoded signals to meet multi-speed and multi-position measuring and feedbadk requirement at same time.

Description

(1) Technical field [0001] The invention belongs to a photoelectric sensor in the technical field of automation control. (2) Background technology [0002] Everyone knows that the photoelectric shaft encoder is the most widely used and most suitable sensor in photoelectric sensing technology, and it is divided into two forms: absolute encoder and incremental encoder. However, before the present invention, we have not found a composite multifunctional encoder that can output both absolute and incremental encoded signals on the same encoder, nor have we found relevant technical information. (3) Contents of the invention [0003] The technical problems to be solved in the present invention are 1. The manufacture of the composite code disc and the simultaneous output of N groups (N>2) M-bit (M>4) absolute coding patterns and a composite multifunctional encoder within one week A group of incremental coding patterns; 2. The structural form of the composite multifunctional...
