摘要
Abstract
According to the simulation requirements of unmanned aerial vehicle(UAV)data link system in reliability design and validity verification,a simulator is designed,in which a domestic field programmable gate array(FPGA)is used as the main control chip to generate virtual trail information,simulate link data analysis and communication protocol conversion.The method combining the sliding window data processing method(Sliding Window Acquisition)and the circular cache is adopted to achieve the parallel cache and calculation of virtual trail information.The Add Sum Check method for data flow is used to realize error control in communication.Parallel access data is used to simulate multi-port RS422 airborne bus communication.Communication between the simulator and the UAV ground station is implemented by the Gigabit Ethernet UDP broadcast method.With the star topology structure,FPGA completes the data rotation and dispatch of the task load equipment in the system.When the data frame length is 1 200 B,the transmission rate of the simulator Ethernet is 947.52 Mb/s.The research results have certain engineering application value in simulation of UAV data link system.关键词
