Problems solved by technology

Frequency hopping communication has gradually become popular in aircraft models in recent years, but there are also shortcomings. The spectrum of frequency hopping communication is fixed. Once there is a fixed source of interference on the flight site, the model will face the danger of losing control.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] Such as figure 1 The present invention shown is realized in the following way, the first step, the selection of RF frequency hopping communication points: the RF communication points are divided into two categories, the first type is static communication points (P11 ~ P1m), and this type of communication points is determined by the device ID These static communication points are evenly distributed in the entire frequency band of the ISM used to increase the anti-interference ability when obtaining synchronization and reduce the time required for obtaining synchronization; the second type of RF communication point is Dynamic communication points (P21~P2n). When the transmitter is turned on, it scans the full-band RSSI of the ISM used in the current electromagnetic environment, and selects the frequency point that meets the requirements and has the best quality as the ...

Abstract

The invention discloses a frequency hopping communication method for a model airplane. Communication points are divided into the static communication points and dynamic communication points, and the two kinds of communication points are combined to form a frequency hopping meter with the high interrupting reconnection function and the high anti-jamming performance. Effective and rapid synchronization is achieved through the static communication points, the environmental electromagnetic interference is shunned through the dynamic communication points, and therefore control failures of the model airplane in the complex electromagnetic environment can be reduced.

Description

technical field [0001] The invention relates to a frequency hopping communication method for aeromodelling. Background technique [0002] The original method of aircraft model remote control communication is fixed-frequency communication, transmitting and receiving fixed frequency points. Users of the same flight site must communicate with each other to avoid interference that may damage the model aircraft or cause personal injury. Frequency hopping communication has gradually become popular in aircraft models in recent years, but there are also shortcomings. The spectrum of frequency hopping communication is fixed. Once there is a fixed source of interference on the flight site, the model will face the danger of losing control. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a frequency-hopping communication method for aeromodelling, which can interrupt reconnection and has good anti-interference p...
