Abstract

The invention relates to a frequency hopping channel selection method and device, a communication method and device and a communication system. The method comprises the following steps: acquiring transmitting power information of a plurality of first channels in a working frequency band range of a transmitting end and signal intensity attenuation information of a plurality of second channels in a working frequency band range of a receiving end; acquiring signal strength information of the plurality of channel groups according to the transmitting power information and the signal strength attenuation information; and obtaining first probability distribution according to the signal strength information, and selecting a plurality of first alternative channel groups corresponding to the signal strength information distributed in a preset probability range in the first probability distribution as a target channel group, so as to improve the fluctuation problem introduced by different gains and insertion losses of different frequency bands on hardware, and improve the accuracy of interaction. Meanwhile, the target frequency hopping group is selected in advance before communication interaction, so that the time spent on frequency hopping channel selection in the communication interaction process can be shortened, and the communication efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of bluetooth, in particular to a frequency hopping channel selection method and device, a communication method and device, and a communication system. Background technique [0002] With the development of the Bluetooth technology, there are more and more application scenarios of the Bluetooth device. For example, in related technologies, the automatic locking or unlocking action of the vehicle-mounted device can be realized through the Bluetooth technology. [0003] However, the Bluetooth working mechanism adopts conventional frequency hopping or adaptive frequency hopping, which mainly defines the target channel for frequency hopping according to the degree of interference of the channel, and does not distinguish the fluctuations caused by the different gain and insertion loss of different frequency bands on the hardware. Therefore, the Bluetooth power transmitted by the Bluetooth transmitter has ...
