摘要
针对航标监控终端对低功耗、高可靠性的要求,采用双MCU架构设计。在软件系统中建立多任务消息机制,引入时限服务策略对任务的运行时间进行约束,只需定时器和少量资源,提高了软件的可靠性。实际应用表明,该终端的性能指标完全满足设计要求。
A pharos monitor system based on double MCUs is developed to lower its power cost. Both multi-task architecture and message mechanism are built in MCU's software. A strategy in which task time is limited in a range is applied to improve software's reliability.
