ARINC661目标符号显控方式的研究与设计

摘要

针对ARINC661座舱显控系统目标符号实现方式繁琐冗余、DF开发者工作量大的问题,研究了自定义窗体部件及其参数接口,设计了一种新型显示项,可以依据DF文件中的设置信息以及UA指令中的配置信息,组合出复杂的目标符号.仿真显示试验表明,该设计合理,运行可靠,在不增加CDS内存占用率和通信指令的基础上,大大减小了预定义符号库以及DF开发者的工作量,同时也便于后期维护.%Considering the complexity of ARINC661 cockpit display and control system in realizing target symbols,and the heavy workload of DF developer,we studied the user-defined widgets and parameter interfaces on the basis of ARINC661 specification,and designed a new type of display item.It can present complex composite target symbols in accordance with the setting information in the definition files and the configuration information in the UA instruction.The simulation results show that the design is reasonable and reliable,which can greatly reduce the size of predefined symbol library and the workload of DF developer without increasing the CDS memory usage and commtnication data.It is also convenient for later maintenance.
