Data Transmission System Used between Counter rotating bodies and Design Method of the System

A data transmission system used between counter rotating bodies that adopts the data transmission method based on the alternation between several launching units and several receiving units, is characterized in that:

• it consists of a data acquisition unit, one-to-N1 branching unit, N1 launching units, N2 all-in-one combiner, N2 receiving units, and data processing equipment;
• N1 launching unit and one-to-N1 branching unit are set on one counter rotating body;
• N2 all-in-one combiner and N2 receiving units are set on the other counter rotating body;
• The number of the N1 and N2 is determined according to the effective launching range as the working range of the launching unit and the effective receiving range as the working range of the receiving unit;
• One of the launching units and one of the receiving units are evenly arranged on the closed movement path of the rotating body, and the maximum interval between two adjacent units of the other one is the closed movement path divided by its number and then deducted by the working range of the former one;
• When the data transmission system between the counter rotating bodies works, the data acquired by the data acquisition unit are sent to N1 launching units by one-to-N1 branching unit;
• One pair or several pairs of the N1 launching units and N2 receiving units, of which the working range coincides with each other, have data transmission between them;
• The receiving unit that receives data sends the data to the data processing equipment through the N2 all-in-one combiner.
