Method for contact-free energy and signal transmission on textile machines, especially twisting machines as well as device for performing the method |
摘要 |
In a method for a contact-free energy and signal transmission for a textile machine between a first stationary part and a second stationary part separated by an air gap, wherein at least one component consisting of an electrically non-conducting material is moved through the air gap, wherein an alternating current signal of a frequency of at least 10 kHz is inductively transmitted by a transformer, having a primary side arranged at the first stationary part and a secondary side arranged at the second stationary part, wherein the primary side and the secondary side are separated by the air gap, a transformer is employed having only one coil pair. Energy and signals are transmitted via the one coil pair by a common carrier signal. The carrier signal provides energy transmission. The signals to be transmitted are imprinted onto the carrier signal as a frequency modulation such that the carrier signal jumps between two frequency values having a fixed spacing. The frequency jumps are evaluated at the secondary side as bit-serial signals, and control signals are generated from the bit-serial signals.
