基于WPF的遥测CAS信息实时监控系统设计开发

在当前试飞模式下,立足于某型客机机组告警系统(Crew Alerting System,简称CAS)信息复杂、重构平台单一等不足,设计了一套CAS信息实时监控系统。系统基于WPF(Windows Presentation Foundation,简称WPF)框架,采用数据访问层、业务逻辑层和显示层组合的典型三层架构,以遥测脉冲编码调试(Pulse Code Modulation,以下简称PCM)数据为输入,结合DataBinding数据驱动模型和XAML等技术实现了CAS信息的实时解析、传输、分发及显示。同时,极大地降低了系统间的耦合性,提高了实时性能和系统的可维护性。通过滑行、首飞等试验的充分验证,系统实现了该型客机CAS信息的100%地面复现,为后续民机试飞测试、监控技术的创新提供了参考依据。

Design and Development of Telemetry CAS Information Real-time Monitoring System Based on WPF

In the current flight test mode,based on the lack of CAS information of a passenger aircraft and the single reconstruction platform,a set of CAS information real-time monitoring system was designed. Based on the WPF framework,the system uses telemetry PCM data as input,and uses a typical three-layer architecture,combined with Data Binding model and XAML technology to realize real-time parsing,transmission,distribution and display of CAS information. At the same time,the system greatly reduces the coupling between systems,improving real-time performance and system maintainability. Through the full verification of the tests such as taxiing and first flight,the system realized 100% ground recurrence of CAS information of this type of passenger aircraft,which could provide a reference for the subsequent innovation of flight test and monitoring technology of civil aircraft.
