Abstract

The invention relates to the field of communication, and discloses a communication frequency point dynamic switching method, an Ad-Hoc network node, and an unmanned plane remote control system. According to the invention, the method comprises the steps: starting a communication frequency point mechanism when the Ad-Hoc network node detects that the communication quality decreases to a certain threshold value; notifying an opposite end node to obtain measurement time slots with the fixed interval for measuring pilot frequency points; carrying out the measurement of the pilot frequency points in a pilot frequency list in the measurement time slots, so as to capture the clean pilot frequency points to serve as target frequency points for frequency point switching; and carrying out the switching of communication frequency points. Therefore, the method can dynamically switch the communication frequency point to a clean frequency point when the Ad-Hoc network is disturbed by interference, and guarantees the communication quality of the Ad-Hoc network. Moreover, the method is simple in implementation, and does not need to increase hardware cost.

Description

technical field [0001] The invention relates to the field of communication, in particular to a technology for switching communication frequency points between nodes of an ad hoc network. Background technique [0002] The wireless spectrum used for ad hoc network communication is generally ISM ((Industrial Scientific Medical)) shared frequency band or dedicated application frequency band. These frequency bands are characterized by being easily interfered and relatively narrow, so how to avoid interference more flexibly The frequency selection switching in the inter-communication is an important key technology in the ad hoc network communication. [0003] For example, as two nodes in the ad hoc network, the drone and the remote control. At present, the communication between the UAV and the remote control is to manually set a frequency point at the beginning of the UAV, or to find a clean frequency point with less interference as the center frequency point for sending and rece...
