摘要
随着民用飞机电源系统逐渐智能化,现代民用飞机的座舱显示系统中也加入了断路器显示与控制相关界面,实现在驾驶舱中达到对电源系统断路器的可视及可控。基于保证驾驶舱显示界面数据完整性的目的,结合ARINC661标准与应用软件的功能,提出了一种具备UA间数据同步的CBIC系统通信方法。针对ARINC661规范和CBIC系统进行简单概述,在对CBIC系统的具体通信流程进行分析后,设计出一种UA之间数据同步的方法,并通过单片机进行仿真实验,实现了UA切换时数据与指令的一致,该方法可以为后续相关的研究工作提供参考。
With the gradual intellectualization of the power supply system of civil aircraft,the cockpit display system of modern civil aircraft has also added the interface related to circuit breaker display and control to achieve the visibility and controllability of the circuit breaker of the power supply system in the cockpit.In order to ensure the data integrity of cockpit display interface,a CBIC system communication method with data synchronization between UAs is proposed based on the ARINC661 standard and the function of application software.The ARINC661 specification and the CBIC system are briefly summarized.After analyzing the specific communication process of the CBIC system,a method of data synchronization between UAs is designed.Through the simulation experiment of the single chip computer,the consistency of data and instructions during the UA switching is achieved.This method can provide a reference for the subsequent related research work.
