摘要
嵌入式系统处于单独应用的阶段,以MCU为核心,与一些监测、伺服、指示设备配合实现一定的功能。嵌入式视频监控系统存在死机、服务无响应等故障,导致无法长期有效地提供服务,系统可用性能低。借鉴商业高端服务器领域一些成功的高可用性的建设方案,结合目前嵌入式领域健壮性技术,在保证不增加硬件成本的前提下,设计一个声音监控的高可用实施方案。文中阐述如何选择支持嵌入式的硬件系统及怎样将μC/OSII嵌入式操作系统移植到Intel X86来开发监控系统。此系统可以定时和实时监控声音,具有查询声音日志、用户注册等功能。
The applications of embedded system are still stay in the separate phases. The MCU is the core and it cooperates with monitoring,servo and indicating equipments to realize some functions. But an embedded audio-monitor system has got the malfunctions of crash and services non-response,thus it＇s unable to provide services effectively in the long term, and result in a low - performance system. Here the author borrows some successful and highly available ideas and plans from commercial high- end servers＇ areas, combining the advanced technology in embedded system, ensuring no additional costs for hardware, and designs a highly available sound monitoring program. In this paper, the ttC/OSll embedded operating system migrated to Intel X86 for developing monitor-control sytsem. This system can monitor audio by timing or real-time,query audio log and users registration.
