The invention relates to a power-maintained multi-circle absolute value encoder. A power-maintained multi-circle absolute value encoder is always one of the most important technologies in industrial control and for the industrial control, encoder application has practical significance. However, it is critical to know how to accurately apply an encoder technology to reduce losses in the industrial control. According to the provided encoder, a low power consumption multi-circle absolute value technology is employed, so that it can be ensured that a vital role can be played in whole industrial control.
Description
technical field [0001] The invention relates to the application of the control system, in particular to the gate opening and height control, height signal hand, independent from the double loop, redundant control. It is suitable for measuring the lifting height of various lifting equipment, underground depth of coal mines, underwater depth of ships, and lifting height of dam gates. Background technique [0002] At present, the traditional multi-turn absolute encoder is completed by a photoelectric code disc and a micro reducer, and an electronic photoelectric multi-turn absolute encoder with a photoelectric encoder and a single-chip microcomputer is also used. Traditional photoelectric encoder code discs are made of glass, metal, and plastic. The glass code disc is made of thin scribed lines deposited on glass. Its thermal stability and accuracy can meet common standards and general requirements, but it is easily broken. The metal code disc is directly engraved with pass...
