The energy supply and signal transmission requires the use of slip-rings or contactless forms of transmission, such as rotary transformers or telemetry systems.
能源供应和信号传输需要滑环或接触传播的形式，如旋转变压器或遥测系统的使用。

In the past, signal between stationary platform and rotary platform transmitted by electronic slip ring in order to realize remote control.
早期，旋转平台间的信号传输与控制采用电滑动环旋转传输电信号来实现。
