Wireless technology relates to a communication slip ring based on wireless technology belonging to the field of communication technology.With the development of online monitoring technology, the application of data transmission between rotating equipment and fixed equipment is increasing (motor, generator, radar, etc.). Traditionally, mechanical multi-path electromechanical slip ring is used to connect the rotating part and fixed part for data exchange.The performance of electromechanical slip ring itself has certain limitations. If there is friction torque, its life is relatively short and its ability to resist electromagnetic interference is relatively poor.

With the development of optoelectronic technology, optical fiber slip ring has been developed.Compared with the electromechanical slip ring, the fiber optic slip ring has the advantages of no friction, long life, no electromagnetic interference, no crosstalk, and no radiation signal.

At present, domestic use of optical fiber slip ring is mostly imported products, only a few domestic manufacturers can develop reliable and practical products.In addition, electromechanical slip ring and optical fiber slip ring also have the limitation of the number of channels, the more the number of channels, the larger the volume of slip ring, it is difficult to meet the needs of modern product miniaturization.
