Identifying method and identifying system for centrifuge rotor

A identifying method for a centrifuge rotor, based on an identifying system for the centrifuge rotor comprising a code disk having a plurality of pairs of magnetic poles, a Hall sensor, and a controlling device;

• the method comprising:
• detecting a duration of each level signal generated from the Hall sensor with the code disk having one revolution according to a predetermined code rule;
• determining a preliminary code according to a total number of windows of the code disk and the duration of each level signal;
• determining a code starter according to the predetermined code rule;
• and
• ordering the preliminary code to obtain a rotor final code based on the code starter, to identify rotor types according to the rotor final code,
• wherein the determining a preliminary code according to the total number of windows of the code disk and the duration of each level signal, comprises:
• determining a unit duration according to the total number of windows of the code disk and the duration of each level signal;
• determining a window interval number of each level signal based on the unit duration;
• and obtaining a preliminary code according to the window interval number of each level signal;
• wherein the unit duration is an interval duration of adiacent windows,
• wherein the determining the unit duration according to the total number of windows of the code disk and the duration of each level signal comprises:
