摘要
介绍了一种智能仪表的实时控制软件的设计与实现 ,针对其中的中断机制、实时措施、可靠性措施和数字显示等关键技术进行了阐述。这些技术应用于某型高空无线电高度表 ,使其测高值达到 1 50 0 0 m(填补国内空白 ) ,误差为低空 1 %、高空 2 % ,并首次使用模拟、数字两种显示方式 ,从而从预研转为工程阶段。
To meet the needs of Chinese aircraft instrumentation, the real-time control software for a intelligent wireless attitude meter was designed and implemented. The architecture of the software was given. The two key techniques, interrupt mechanism and reliability measures were presented. The interrupt responses were divided into interrupt service request and interrupt service, so the continuous services were allowed while requests for servicing were being accepted. The reliability measures consist of set-up for watchdog voltage, fault display and redundant codes. The designed altitude meter has been put in service.
