Abstract
The invention provides a short distance based remote controller pairing method and a remote controller pairing circuit. The short distance based remote controller pairing method comprises the following steps: presetting step, namely, presetting regular buttons as pairing buttons, and presetting the effective distance for remote controller pairing; pairing distance judging step, namely, judging whether the distance between a remote controller and a receiver is less than the effective distance after detecting that the pairing buttons of the remote controller are pressed down, and skipping to the pairing control step if yes, otherwise, determining that pairing fails; and pairing control step, namely, controlling the remote controller by a built-in MCU to enter a pairing mode to complete pairing, and returning to a normal operation mode after pairing. According to the invention, the pairing buttons of the remote controller and the effective distance for pairing are preset in advance, and when the distance between the remote controller and the receiver is within the effective distance, the pairing is successful; when the distance between the remote controller and the receiver is greater than the effective distance, the pairing is failed, and the remote controller is prevented from being paired to other receivers.
