【摘要】 阐述了基于Nios Ⅱ软核的内河航标监控系统的设计方法,及AD7862控制电路的VHDL设计。从系统的角度提出航标监控系统的完整设计方案,给出基于Nios Ⅱ的航标监控终端硬件设计框图,并得到在Modesim中进行仿真的结果。根据现场运行情况显示,系统能实时地监测航标的工作状态,达到系统工业级的品质保证,并且具有高可靠性、高实时性和维护方便性等优点。更多还原

【Abstract】 An introduction is given on how to design scheme for the Navigation Mark Monitoring System based on Nios Ⅱ soft core,and how to design the VHDL of AD7862 control circuit.The intact designing scheme is put forward from the systematic angle and the block diagram of the controller is drawn based on Nios Ⅱ soft core.The result is obtained from the simulation on Modesim.Testified by on-spot function,this system can realize real-time supervision the working status of the Navigation Mark and meets industrial standards,and is highly reliable,stable and convenient to maintain.更多还原
