许多人都在试图给物联网(Internet of Things,IoT)一个定义。其实,作为一个硬件和软件工程师,你已经知道物联网的最重要的元素——构建物物互联的产品。嵌入式系统在物联网开发中正在起着关键的作用。广义地讲,物联网系统有以下4个主要的部分,如图1所示。◆物本身(设备)。◆局域网(本地网络):包括网关,它将私有的通信协议翻译成互联网协议。◆互联网。◆后台服务:企业数据中心、PC和移动设备。
Many are trying to define the Internet of Things (IoT). In fact, as a hardware and software engineer, you already know the most important element of the Internet of Things - the building of the Internet of Things. Embedded systems are playing a key role in IoT development. Broadly speaking, IoT system has the following four main parts, as shown in Figure 1. The object itself (equipment). ◆ LAN (Local Area Network): Includes gateways that translate proprietary communication protocols into Internet protocols. ◆ Internet. ◆ background services: enterprise data center, PC and mobile devices.
