The invention discloses a railway turnout position measuring device and method based on magnetic coding, which are applied to the field of railway traffic safety, and are characterized in that a magnetic coding generation system is arranged on a railway turnout and is used for generating magnetic coding information with specific spatial distribution to serve as a turnout magnetic field information identifier; the magnetic detection system is distributed in a turnout movement area and used for detecting magnetic field change information of the area in the turnout movement process. And the data processing system is used for constructing local area magnetic field distribution in the turnout movement process according to the magnetic field change information obtained by the magnetic detection system, and extracting actual characteristic information of the local area magnetic field distribution to determine whether the railway turnout is manipulated to a target position. According to the device, the accuracy and reliability of measuring the railway turnout position are improved.
