2017年11月6日,中国上海——Arm宣布推出Mbed Edge,进一步拓展Mbed Cloud的设备管理能力,在边缘侧,即物联网网关上实现设备的接入、控制和管理。
网关在物联网网络中发挥着至关重要的作用,是本地连网设备(包含有线与无线设备)与云端之间的桥梁,通常在本地运行应用程序以实现设备控制。网关失效将对本地生产运营带来灾难性的后果,可能导致生产线停滞,甚至是关停风力发电机组。得益于Mbed Cloud新增的Mbed Edge能力,Mbed Cloud将能够实现三大功能,包括连接和管理异构连网设备、网关管理和诊断以及边缘计算。
l 协议转换:许多传统连网设备使用的通信协议与IP网络协议不兼容,比如 Modbus和BACnet,Mbed Edge可以转换这些协议,使得这些设备与基于IP网络协议的设备一样由Mbed Cloud管理起来 。
l 网关管理:Mbed Edge的一系列新特性可以提升物联网网关的持续服务能力,最大程度缩短代价高昂的停机时间。关键性能包括预警通知,流程、资源和接口管理,还有详细本地诊断能力。
l 边缘计算:Mbed Edge将提供本地应用执行环境以及相关的计算资源,从而在网关上即可进行规则运算和数据处理。如此,即使本地网络与外网断开连接,本地业务仍然可以持续进行,降低对生产力的影响。
“到2020年,物联网项目使用网关的比例将从现在的60%提升至90%。”

Arm 提供了物联网领域市场占有率最高的计算解决方案,整个生态体系的合作伙伴已出货超过1000亿台基于Arm技术的设备,为此Arm积极扩展其设备管理功能以满足顾客对于物联网设备的安全和生命周期管理的需求。
Arm物联网集团网络服务事业群总经理 Hima Mukkamala 表示,“我们将继续履行我们的使命,帮助合作伙伴和客户简单、安全、无缝地管理所有物联网边缘设备。”
研华科技嵌入式物联网总经理张家豪表示,“Mbed
Edge大幅扩展Arm
Mbed Cloud的涵盖层面,能安全管理那些没有直接连到云端的设备,例如我们的WISE-1510
LoRA IoT传感器节点模块。作为领导伙伴厂商,我们在WISE-3610
IoT网关产品中内建Mbed
Edge解决方案,并希望在未来其他的网关平台中也支持Mbed
Edge。”
通过与部分客户和合作伙伴的产品测试后,Mbed Cloud现已正式向所有客户与合作伙伴全面开放。Mbed Edge的协议转换功能目前已推出预览版。
