Remote control system

摘要

A remote control system capable of utilizing manually encoded signals is disclosed. The system is particularly suitable for use in the logging industry because it is capable of utilizing standardized whistle signals for both remove control and audible signalling purposes. The system includes a transmitter for transmitting a manually encoded signal. The control signal is received by a receiver and is decoded by a decoder that reduces the manually encoded signal to a digitized signal. The digitized signal is compared with a set of reference digitized signals, and if a match is found, a corresponding output control signal is applied to a controlled device such as a yarder.
