The Design And Realization Of UAV Reconnaissance System Based On Mind Control

UAV Reconnaissance(UVA-R)is one of the important reconnaissance means of military,it can often obtain timely and accurate information by surprise in a rapidly changing battlefield environment.At the same time,the brain computer interface(BCI)technology is developing rapidly in recent year,and its application is expanding to the UAV-R field.About the research focus,we disign and realize a UVA-R system based on mind control.Firstly,this paper analyzes the functional requirements of UAV-R system,and proposes a design scheme of UVA-R system based on mind control.The system can be equipped with class or rank units,recognise the soldier's mind,supplemented with head movements and facial expression,generate flight command,and transfer reconnaissance information in the form of video to the ground station to stimulate the soldier for producing a new follow-up flight command,and then complete the reconnaissance mission.For the wireless transmission of flight information,the data transmission module(DTM)is disigned taking STM32F103C8 processor and A7139 chip as the core,and the driver of the wireless transceiver based on the hardware is completed,then the data transceiver function with 433 MHz between ground station and UAV is realized.According to the functional requirements of the system,the ground station software is designed,functions like soldier status recognition and reconnaissance video real-time display and playback are implemented;combineding with database flight command and soldiers state relationship mapping,system information configuration and storage are completed,and a communication protocol between ground station software and DTM is made.In order to meet the security requirements of battlefield applications,the paper also studies the encryption method of information in the DTM,selects the Koblitz curve of GF(2163)based on the basic principle of Elliptic Curve Cryptosystem(ECC),determins the overall scheme of FPGA data encryption and decryption circuit,gives the structure design of key modules.At the same time,an evolution algorithm based on hybrid hardware repair strategy is proposed in order to achieve the self-repair of circuit;compared with other similar algorithms,the algorithm can reduce the combinational logic circuit design time and area effectively.After the overall system design and software-hardware design and debugging,this paper has completed the principle prototype of UAV-R system,which has the characteristics of soldier status recognition,wireless data transmission,control mode self-configuration,reconnaissance video ground station display and playback,and the flight performance in Yixing contest launch ceremony.
