OneOS概述

OneOS是中国移动针对物联网领域推出的轻量级操作系统,具有可裁剪、跨平台、低功耗、高安全等特点,支持ARM Cortex-A和 Cortex-M、MIPS、RISC-V等主流芯片架构,兼容POSIX、CMSIS等标准接口,支持Javascript、MicroPython等高级语言开发模式,提供图形化开发工具,能够有效提升开发效率、降低开发成本,帮助用户快速开发稳定可靠、安全易用的物联网应用。

OneOS架构

OneOS总体架构采用分层设计,主体由驱动、内核、组件、安全框架组成。采用一个轻量级内核加多个系统组件的模式,加上海量硬件的适配支持,使OneOS具备极高的可伸缩性与易用性。操作系统整体架构如下图:

内核

极简的设计思路,在减少资源开销的情况下兼具优秀的实时响应特征,支持多任务管理调度,提供丰富的IPC策略,如信号量、互斥量、消息队列、邮箱等,提供了高效可靠的RTOS内核支撑。

驱动

提供丰富的BSP板级支撑,适配超千款MCU,支持ARM、RISC-V、MIPS、Xtensa、C-Sky等主流架构,通过抽象设计,将所有外设以设备方式进行管理,极大提升了应用开发的便利性。

组件

提供包括网络协议、云平台接入、远程升级、文件系统、日志系统、测试框架、调试工具等众多通用服务能力,也包括高精度定位等专业应用领域的完整解决方案。由于采用了模块化的设计,因此各个组件相互独立,耦合性低,易于灵活裁剪。

安全管理框架

终端侧基于信任根实现轻量级的主动检测和可信度量,提供轻量级的密码算法库及轻量级密钥管理与密钥协商机制,实现端到端安全通信。平台侧基于大数据态势感知技术,帮助用户建立端侧安全画像,根据应用场景制定不同的安全管理策略。

OneOS特点

灵活裁剪

抢占式的实时多任务RTOS内核,支持多任务处理、软件定时器、信号量、互斥锁、消息队列、邮箱和实时调度等特性,RAM和ROM资源占用极小。可灵活裁剪,搭配丰富组件,适应不同客户需求。

跨芯片平台

应用程序可无缝移植,大幅提高软件复用率。支持的主流芯片架构有:ARM Cortex-A和Cortex-M、MIPS、RISC-V等。支持几乎所有的MCU和主流的NB-IOT、4G、WIFI、蓝牙通信芯片。

组件丰富

提供丰富的组件功能,如互联互通、端云融合、远程升级、室内外定位、低功耗控制等。同时提供开放的第三方组件管理工具,支持添加各类第三方组件,以便扩展系统功能。

易于开发

一站式开发工具OneOS Studio可用于对内核和组件的功能进行配置,支持组件自由裁剪,让系统按需进行积木式构建,同时可帮助用户跟踪调试,快速定位问题。

低功耗设计

支持MCU和外围设备的功耗管理,用户可以根据业务场景选择相应低功耗方案,系统会自动采用相应功耗控制策略,进行休眠和调频调压,有效降低设备整体功耗。

安全设计

针对物联网设备资源受限、海量连接、网络异构等特点,参考等保2.0及《GB/T 36951-2018 信息安全技术 物联网感知终端应用安全技术要求》等规范,在系统安全、通信安全、数据安全等方面提供多维度安全防护能力。

OpenCPU开发框架

支持通信SoC芯片OpenCPU开发模式,为开发者带来屏蔽复杂通信芯片差异的高效开发方式,提供统一开发体验。同时,在同样的业务功能下,减少了设备额外MCU开销和存储器的使用,大幅降低设备成本。
