基于物联网的计算机嵌入式操作系统设计

Design of computer embedded operating system based on Internet of Things

随着微处理器性能的快速提升及5G通讯技术的普及,基于物联网的嵌入式操作系统需求不断增大。针对上述问题,文中设计了一款搭载于嵌入式硬件系统环境的操作系统。为了满足该嵌入式操作系统的安全需求,使用多重独立等级安全架构设计分区分时操作系统,利用UDP通讯网络实现组网内的信息共享,采用任务备份系统提高操作系统的稳定性。为了提高可移植性与可维护性,系统采用软硬件分离的设计策略。在基于嵌入式系统的实验测试中,该操作系统的准确性可达到99%以上,且硬件无宕机工作时间长,具有良好的实时运行性能。

With the rapid improvement of microprocessor performance and the popularization of 5G communication technology,the demand of embedded operating system based on the Internet of Things is increasing.In order to solve these problems,this paper designs an operating system which is installed in the embedded hardware system environment.In order to meet the security requirements of the embedded operating system,the multi independent level security architecture is used to design the partition time⁃sharing operating system;the UDP communication network is used to realize the information sharing within the network;the task backup system is used to improve the stability of the operating system.In order to improve the portability and maintainability,the system adopts the design strategy of hardware and software separation.In the experiment test based on the embedded system,the accuracy of the operating system can reach more than 99%,the hardware has a long working time without downtime,and has good real⁃time performance.
