Abstract

The invention relates to a radio frequency equipment communication method and device. The method comprises steps: pair code information is generated according to the first equipment identification code information of the radio frequency equipment and the second equipment identification code information of opposite-end equipment; seeds of a pseudo random frequency hopping sequence are generated based on the pair code information; according to the seeds of the pseudo random frequency hopping sequence, a frequency hopping sequence is generated; and based on the frequency hopping sequence, frequency hopping switching is carried out. The pair code information is generated according to the first equipment identification code of the radio frequency equipment and the second equipment identification code of the opposite-end equipment, the pair code information is used to generate the seeds of the pseudo random frequency hopping sequence, the frequency hopping sequence is further correspondinglygenerated, and finally, according to the frequency hopping sequence, frequency hopping switching is carried out. Frequency hopping switching is carried out according to the frequency hopping sequence, and thus, the problem of co-frequency and adjacent-frequency interference can be effectively avoided, and the hardware overhead and the cost can be greatly reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method and device for radio frequency equipment. Background technique [0002] The ground remote controller of drones and other equipment communicates with the aircraft in the air through radio frequency transceiver devices, often there will be a lot of same-frequency and adjacent-channel interference, which not only includes multiple remote controllers and / or multiple aircraft Mutual interference also includes the interference of other electronic devices in the same frequency band to the remote control and aircraft. Therefore, frequency hopping is often used in the radio frequency communication process to avoid interference between different devices. [0003] At present, the frequency hopping communication protocols of communication methods such as WIFI and Bluetooth are often too complicated, requiring the hardware implementation of radio frequency transceiver ...
