Abstract

An automatic frequency hopping remote controller automatically switches its channel when the transmission of a remote control signal is interfered. The remote controller includes a transmitting end and a corresponding receiving end; the transmitting end includes a first signal transceiver capable of transmitting signals through several channels and an input device, such that the remote control signal can be transmitted from a predetermined channel by a trigger instruction of the input device, and the receiving end is a second signal transceiver installed in an electronic device for receiving the remote control signal from the transmitting end. If the quality at a received signal is evaluated as poor, the remote controller will automatically switch to another receiving channel and send a frequency hopping signal to the transmitting end, so that the transmitting end will switch to that channel correspondingly, and the next remote control signal will be transmitted through that channel.

Claims

1. An automatic frequency hopping remote controller, transmitting information by a radio frequency signal, and automatically switching channel thereof when a remote control signal is interfered, and said remote controller comprising:

at least one transmitting end, including a first signal transceiver capable of transmitting a signal from a plurality of channels and receiving a signal from a fixed channel, and an input device, and a remote control signal being transmitted from a predetermined channel by a trigger instruction of said input device; and

a receiving end, including a second signal transceiver capable of receiving a signal from a channel corresponding to said transmitting end and transmitting a signal through said fixed channel, for receiving a remote control signal from said transmitting end, such that if the quality of said received signal is evaluated as poor, said receiving end will automatically switch a receiving channel and send a frequency hopping signal to said transmitting end through said fixed channel to set a transmitting channel to the same channel as that of said receiving channel.

2. The automatic frequency hopping remote controller of claim 1, wherein said channel of said receiving end is switched in a predetermined sequence.

3. The automatic frequency hopping remote controller of claim 1, wherein said channel of said receiving end is switched at random.

4. The automatic frequency hopping remote controller of claim 1, wherein in said receiving ends come with a plural number and are installed separately in different devices.

5. The automatic frequency hopping remote controller of claim 1, wherein said receiving end evaluates said received remote control signal according to a threshold of an electric property and examines whether or not said electric property of said received remote control signal exceeds said threshold as an evaluation standard.

6. The automatic frequency hopping remote controller of claim 5, wherein said electric property is a signal/noise ratio.

7. The automatic frequency hopping remote controller of claim 1, further comprising a manufacture ID to said remote control signal and/or said frequency hopping signal for enhancing the level of identifying said signal.

8. The automatic frequency hopping remote controller of claim 1, wherein said transmitting end further comprises a light indicating lamp.
