Abstract
The invention provides a remote control device. The invention comprises a coding converter allowing normal coded data to calculate with a set pseudorandom data sequence to obtain anti-interference coded data, and then to perform transmission. Through setting different pseudorandom data sequences to different devices, the devices apply completely different transmission data and mutual interferences can be completely avoided when the devices are remote controlled even if the devices are the similar devices with the same model. If a standardized receiving terminal is not provided with the coding converter, the remote control interference problem can be resolved through changing a transmitting terminal and adding a remote control transponder. The coding converter can be arranged in a processor of the transmitting terminal and the receiving terminal, realized by software without increasing hardware cost; and for the standardized devices, the remote control coding converter is simple and reliable.
