Embodiment

[0135] In order to describe the features and working principle of the present invention more intuitively, a practical application scenario will be described below.

[0136] Such as Figure 8 Shown is a schematic diagram of random frequency hopping in this embodiment. Depend on Figure 8 It can be seen that the remote controller and the aircraft serve as a set of wireless communication devices. exist Figure 8 Among them, t represents the frequency hopping time period, F0 is the synchronization frequency, and F1-Fn are the frequency hopping frequencies.

[0137] First, in this embodiment, the wireless communication device performs device initialization (only one initialization is required for each group of devices), that is, frequency binding. After the remote control and the aircraft enter the linking mode, both devices enter the linking channel. The remote control sends its own device number to the aircraft through the linking channel. After receiving it, the aircraft rep...

Abstract

The invention relates to a random frequency hopping method, a communication device and a random frequency hopping system. The stochastic frequency hopping method comprises the steps that a first communication device sends device information of the first communication device to a second communication device through a frequency matching channel; the first communication device receives frequency matching information sent by the second communication device; the first communication device sends synchronization information to the second communication device through a synchronization channel; the first communication device receives reply information which is sent by the second communication device and corresponds to the synchronization information; the first communication device switches a current communication channel to a first channel in a preset frequency band at interval time t, and the first communication device sends communication data to the second communication device through the first channel, wherein the first channel is the channel corresponding to a number of a random sequence in the preset frequency band, the numbers of the random sequence and the channels in the preset frequency band are in one to one correspondence, and the numbers of the random sequence are generated according to the device information of the first communication device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a random frequency hopping method, communication equipment and a random frequency hopping system. Background technique [0002] Wireless communication has a variety of frequencies, such as: 2.4GHz, 433MHz, etc. There are multiple communication channels on each frequency, usually dozens to hundreds of channels. Two devices must communicate on the same channel on the same frequency. wireless communication. [0003] Wireless frequency hopping technology has been widely used in the field of wireless communication, but there are many design schemes for frequency hopping methods, and different frequency hopping schemes can be designed according to different technical conditions and application requirements. Existing technologies such as sequential cyclic frequency hopping, a group of channels cyclically hop frequency according to a certain order, there is a problem in s...
