Abstract

The invention discloses a single-code-channel absolute coding method and a coder, and relates to the technical field of measuring instruments, and the method comprises the following steps: setting a condition parameter coding sequence stripe total number N, a coding bit type X and non-repeated coding sequence bits Y and Xlt; ylt; n; according to set N, X and Y, starting from randomly generating X-bit codes, sequentially generating code sequences according to bits; when the length of the coding sequence is Y + 1, judging whether the coding sequence formed by the first to Yth coding bits is the same as the sequence formed by the second to (Y + 1) th coding bits or not, and if so, continuously generating codes according to bits; if not, judging whether the generated coding sequence is equal to N or not; if not, continuing to generate codes according to bits; if so, outputting a coding sequence; and depicting black and white stripes at intervals on the code channel according to the coding sequence. According to the invention, the coding sequence conforming to the rule is randomly generated by means of the computing power of the computer, the coding method is optimized, and the response speed of the encoder is improved.

Description

technical field

[0001] The invention relates to the technical field of measuring instruments, in particular to a single code channel absolute encoding method and an encoder. Background technique

[0002] As an instrument that uses photoelectric technology for non-contact position or angle measurement, the encoder converts physical quantities such as rotational speed, displacement, and angle in mechanical motion into digital electrical pulses, and combines it with digital processing technology and computer technology. Realize Fast, timely and accurate detection and control play an irreplaceable role in the field of position or angle measurement.

[0003] The encoder based on single-track absolute coding is a new type of encoder, which represents one of the most advanced development directions of encoders and meets the needs of encoder miniaturization. The encoding method of the encoder (single code track absolute encoding method) is to engrave a code with specific rules on a...
