Abstract

The invention provides a magnetic grating ruler reading receiving method and device, and the magnetic grating ruler reading receiving method comprises the following steps: carrying out the measurementof a measured object through a magnetic grating ruler, obtaining a displacement signal of the magnetic grating ruler, and transmitting the displacement signal to a level converter; receiving the displacement signal through a level converter, carrying out level conversion, and then transmitting the displacement signal to an upper computer serial port; receiving a data signal of an upper computer serial port, and screening out an A-phase signal and a B-phase signal of the magnetic railing ruler; and monitoring whether the pulse of the A-phase signal or the B-phase signal jumps or not, changingand recording a displacement count value when the pulse of the A-phase signal or the B-phase signal jumps, and recording a corresponding time value through a time counter. The magnetic grating ruler reading receiving method has the advantages of short signal transmission path, high signal transmission speed and high reliability.

Description

technical field [0001] The invention relates to the technical field of receiving magnetic scale readings, in particular to a method, device and electronic equipment for receiving magnetic scale readings. Background technique [0002] The magnetic scale is the reference element of the magnetic scale digital display system. Using a method similar to the recording technology, the process of recording magnetic waves with strictly equal intervals on the magnetic scale (or disk) through the recording head is called magnetic recording. It has been recorded. The magnetic ruler of the magnetic wave is called the magnetic scale. The distance between adjacent grid waves on the magnetic scale is called the wavelength of the magnetic scale, also known as the pitch (grid pitch) of the magnetic scale. The wavelength is the length measurement unit of the magnetic scale. Any measured length can be used with It is represented by the sum of corresponding several grating wavelengths. [0003]...
