Electromagnetic induction potentiometer adaptive for full-stroke detection

An electromagnetic induction potentiometer comprising:

• a movable element configured to obtain an input for position change;
• a permanent magnet attached to the movable element;
• a magnetic induction sensor configured to sense positions of the permanent magnet and generate an initial potential signal;
• and
• a full-stroke adaptive output adjusting unit configured to collect the initial potential signal and adaptively adjust the initial potential signal to an actual potential signal corresponding to a full stroke of position change of the movable element;
• wherein the full-stroke adaptive output adjusting unit comprises:
• an information collecting module, configured to collect the initial potential signal and obtain the initial potential sampling value;
• a signal output module, configured to output the actual potential signal;
• a control module, configured to perform following steps:
• B1:
• obtaining a preset potential sampling range, taking a minimum value of the preset potential sampling range as a minimum value of an actual potential sampling range, and a maximum value of the preset potential sampling range as a maximum value of the actual potential sampling range;
• B2:
• controlling the information collecting module to sample output of the magnetic induction sensor and obtaining the initial potential sampling value;
• B3:
• obtaining an actual potential output value according to a comparison result between the initial potential sampling value and the actual potential sampling range, and controlling the signal output module to output the actual potential signal;
• B4:
• adjusting the actual potential sampling range according to the comparison result between the initial potential sampling value and the actual potential sampling range;
• and
• B5:
• returning to the step B2.
