摘　　要：阐述物联网操作系统的起源和发展历程,总结了物联网操作系统的5大技术特征。笔者对3种物联网操作系统Huawei LiteOS、Amazon FreeRTOS和RT-Thread进行实际使用和评测,并就功能指标进行比较。通过评测和比较得出,3种物联网操作系统具备物联网系统开发所需要的基本功能,可以满足多数物联网边缘节点项目开发需求,相对Huawei LiteOS和RT-Thread,Amazon FreeRTOS无论在功能上、产品成熟度和支持硬件架构上都有相当的优势。最后展望了物联网操作系统在边缘计算和物联网安全方面的最新发展,并指出物联网操作系统的成长生态建设是关键因素。In this paper, the origin and development of Internet of the Things Operating System(IoT OS) and the five technical characteristics of an IoT OS are explained. The feature of Huawei LiteOS, Amazon FreeRTOS, and RT-Thread base on testing and using of them are analysised. In conclusion, all of the three IoT OSes are capable of fulfilling basic IoT node and edge system development requirements. Amazon FreeRTOS clearly has an edge in functionality, platform matureness, and processor architecture support. Future more, the development trends of IoT OS in the edge computing and IoT Security are briefly examined.In conclusion, the author points out that the growth and ecological construction of The Internet of Things operating system is the key factor.
