摘要
Abstract
To address the high cost and extended downtime associated with manual maintenance for aerospace sealed-cabin equipment,this paper proposes a reliable over-the-air(OTA)upgrade solution.The method adopts a dual-image backup mechanism with integrity verification and adaptive network protocols,enabling secure firmware updates of up to 16 MB and automatic rollback in the event of fail-ure.Experimental results show a misdetection probability below 9.32×10-10,while approximately doubling the Flash lifespan,a 99.9%upgrade success rate,and 100%fault recovery.Compared to traditional manual methods,this approach reduces maintenance time from hours to about one minute and lowers costs by over 90%,effectively resolving key maintenance challenges.关键词
