The serial a / d transformation and the channel isolation technology are adopted . eight - channel parallel data acquisition and test data time - sharing storage are realized . verilog hdl ( hardware description language ) is adopted to design the vxi register - based interface circuit and control circuit of each channel 以fpga ( fieldprogrammablegatearray )為控制核心,采用串行a / d變換器和通道隔離技術,實現(xiàn)了8通道并行采集和測試數(shù)據(jù)分時存儲功能,利用veriloghdl ( hardwaredescriptionlanguage )設計vxi寄存器基接口電路及各通道的控制電路。
In view of the problems existing in air traffic control system that there are many types of tracking information and quality of the information is not consistent with time segments technique , a new algorithm , which is based on data of multi - types sensors is presented of time normalizing - extrapolating for data time - alignment 摘要針對空中交通管理中的多種類型航跡信息以及信息質量不一致等問題,采用了聚類的時間片技術,提出一種基于多類型傳感器數(shù)據(jù)信息的時間歸一化外推數(shù)據(jù)對準算法,融合航跡數(shù)據(jù),提高了航跡信息的一致性和準確性。
