Embodiment

[0042] The frequency hopping method based on the radio frequency remote control system in the embodiment of the present invention includes a radio frequency receiving end processing method and a radio frequency remote control processing method,

[0043] Wherein, the radio frequency receiver processing method includes the following steps:

[0044] Step 1. Power on the RF receiving end, scan all channels, and sort them in order from good to poor according to the channel quality, select a certain number of channels in the top of the list to mark.

[0045] In this step, the certain quantity may be 3-6.

[0046] Step 2. The radio frequency receiver chooses to hop to the first channel among the marked channels, and waits to receive the synchronization and data from the radio frequency remote control.

[0047] In this step, it may be specifically as follows: the radio frequency receiving end selects frequency hopping to the highest-ranked channel among the marked channels, waits to ...

Abstract

The present invention relates to a wireless remote control technique. The present invention solves the problem of long synchronization time or high complexity of frequency hopping method in existing radio-frequency remote control system and provides a frequency hopping method based on radio-frequency remote control system, the technical solution of the method is summarized as follows: the difference from prior art is primarily in that: scanning all channels respectively by a radio-frequency receiving end and a radio-frequency remote controller and conducting sequencing according to qualities of the channels in a sequence from good ones to poor ones, selecting a certain number of channels from the top of the sequence for marking, correspondingly conducting frequency hopping according to the marking and sequence in subsequent frequency hopping operations, and if the radio-frequency receiving end receives frequency hopping information sent from the radio-frequency remote controller, correspondingly conducting frequency hopping according to the frequency hopping information, and sending the frequency hopping information for the next frequency hopping to the radio-frequency receiving end by the radio-frequency remote controller after synchronization. The beneficial effects of the present invention are that the method meets the real time needs for the remote controller while meeting the demand of interference resistance and is suitable for a radio-frequency remote control system.

Description

technical field [0001] The invention relates to wireless remote control technology, in particular to a radio frequency remote control system. Background technique [0002] Currently, 2.4G radio frequency remote controllers are used more and more, because the 2.4G frequency band is a public frequency band, there are many devices on this frequency band, including WIFI, Bluetooth and Zigbee, etc. How to prevent the RF remote control system from being interfered by devices in the same frequency band is particularly important. [0003] A good way for the RF remote control system to solve the interference by devices in the same frequency band is to use frequency hopping technology. The carrier frequency of both parties in the communication is controlled by the pseudo-random change code and randomly hops, thereby avoiding the interfered channel and jumping to a clean channel. Make sure the communication is working. [0004] At present, the known radio frequency remote control sys...
