Abstract

The invention discloses a two-channel Gray code magnetic coding device which comprises a collecting device I, a collecting device II and a power supply, wherein the collecting device I comprises a magnetically sensitive element I and a microprocessor I, and the collecting device II comprises a magnetically sensitive element II and a microprocessor II; the magnetically sensitive element I is connected with the microprocessor I, and the microprocessor I receives magnetic field variation sensing signals collected by the magnetically sensitive element I; the magnetically sensitive element II is connected with the microprocessor II, and the microprocessor II receives magnetic field variation sensing signals collected by the magnetically sensitive element II; and the power supply supplies electric energy for the magnetically sensitive elements and the microprocessors. By using the technical scheme of the invention, the magnetically sensitive elements and the microprocessors are used for processing detection signals to form two-channel coding data with extremely small repetition and error rate, interference between a completely independent two-channel data processing system and a power supply system can be avoid effectively, the stability of detection is increased, and the technical problem of large size of an optical coder is solved.

Description

technical field [0001] The invention relates to the technical field of sensor control, and relates to a driver controller encoder device for railway locomotives, in particular to a novel dual-channel Gray code magnetic encoder. Background technique [0002] The driver controller of the Harmony 4 (DJ4) high-power AC electric locomotive developed by ourselves on the basis of imported technology in our country generally uses imported photoelectric encoders. Due to the long import cycle of imported photoelectric encoders, inconvenient installation, and low repeatability of dual-channel data output, it is necessary to develop a new type of encoder to realize the localization of imported locomotive parts and replace imported photoelectric encoders. At the same time, the technical problems of long import cycle, inconvenient installation, low output accuracy and easy detection process of the existing photoelectric encoder are improved. In the prior art, photoelectric angular positi...
