Abstract

The invention discloses a communication protocol extraction method for a micro-miniature civil unmanned aerial vehicle remote control link. The communication protocol extraction method for the micro-miniature civil unmanned aerial vehicle remote control link extracts the time, frequency and data information of the protocol through chip identification, chip communication signal extraction and othermethods, and extracts the data format of the protocol through wireless signal acquisition and other methods. The invention uses a low cost software defined radio device, therefore, the implementationcost of communication protocol extraction is reduced; the implementation method is simple; the means are flexible and has nothing to do with the model of the unmanned aerial vehicle; meanwhile, the invention has low requirements for the expertise and skills of the operator.

Description

technical field [0001] The invention relates to the technical field of safety of civil unmanned aerial vehicles, in particular to a communication protocol extraction method for remote control links of miniature civil unmanned aerial vehicles. Background technique [0002] Civilian UAV technology has developed rapidly in the past few years, and various types of civilian UAVs have been widely used in various civil fields, such as police, urban management, agriculture, geology, meteorology, electricity, emergency rescue, disaster relief, Many areas such as video shooting have played an important role. Its widespread popularity has promoted the development and application of civilian drone technology. However, while civilian UAV technology brings many conveniences to people, it also brings many safety problems to people. For example, drones, as a small and highly flexible aircraft, are very likely to be used by lawbreakers for personal attacks, illegal intrusion, peeping, drug...
