工业网关的功能组成 网关(Gateway)又称网间连接器、协议转换器。网关在网络层以上实现网络互连,是最复杂的网络互连设备,仅用于两个高层协议不同的网络互连。网关既可以用于广域网互连,也可以用于局域网互连。 网关是一种充当转换重任的计算机系统或设备。使用在不同的通信协议、数据格式或语言,甚至体系结构完全不同的两种系统之间,网关是一个翻译器。与网桥只是简单地传达信息不同,网关对收到的信息要重新打包,以适应目的系统的需求。 4G工业网关的基本功能是连接两个异构网络,这在工业物联网场景中尤为常见,因为传感器网络经常使用完全不同于普通网络层(长距离传输网络)的电信号和协议。   4G工业网关功能组成   网络层信号接口 它主要承担网络层信号的对接任务。与感知层信号接口相比,网络层信号接口一般简单得多,因为通常整个系统只需要一个标准的长途网络及其协议,因此相应的硬件接口和数据收发软件相对简单。然而,这并不是说它只能支持一种类型。在实际应用中,工业网关的制造商通常被设计为支持多种形式的长途网络,以实现产品的通用性。特定的表单可以是同时配置多个接口的方式,也可以以配置插件卡的形式设计产品,以便用户可以在离开工厂时选择要配置的不同配置。   传感层信号接口 主要负责传感器网络中各设备信号的对接工作。该模块包括用于不同电信号对接的硬件接口,以及相应的数据采集和指令发送软件。为了解决感知层的复杂性,工业网关厂商将根据各自的目标应用领域,装备感知层信号接口的硬件接口和协议组合。   就地数据库 在一些用于复杂数据处理流程或其他就地业务逻辑处理的场景中,处理后的数据还需要存储在网关本地数据库中。由于工业网关一般属于嵌入式计算设备,所以这类数据库也一般采用嵌入式数据库。嵌入式数据库功能简单,具有内存缓冲,提高了访问速度。   就地的业务逻辑 它主要处理与网关相关的传感器网络部分所连接的设备、传感器和执行器相关的本地系统的业务逻辑。不同网关的本地业务逻辑模块的丰富性和复杂性差异很大。如果工业网关中没有这样的功能模块,它通常被称为数据传输网关、协议转换器或通信管理器。有关就地业务逻辑的详细描述,请参见边缘计算。   数据处理 设备端数据处理主要解决数据不匹配问题。也就是说,服务器所需数据的范围、频率、完整性等等。数据处理的目的是对输入接口中的数据进行排序,将其转换为适合输出的数据形式,并将其推送到输出接口。输入端和输出端可以由设备端或服务器端播放,因此数据流是双向的,并且根据数据类型的不同而不同。   其他功能 除了上面的主要模块之外,网关还常常配置它的功能用户界面,要么使用按钮、命令行(通过Telnet或串口),要么使用图形界面(例如内置的WEB服务器,甚至面板)。如果网关具有适当的业务逻辑,它可能还需要工具来加载脚本文件、配置文件,等等,这些都是本地业务逻辑所需要的。 作为一种远程设备,4G工业网关的自我维护也非常重要。一般情况下,需要利用自己与服务器连接的优势,从服务器上自动下载自己的软件更新包并完成更新。还应通过远程登录完成部分设置和配置工作,以降低外派人员的现场维护成本,提高对用户需求的响应速度。

网关和路由器之间的区别 网关是充当转换代理的计算机系统或设备。网关是两个系统之间的转换器,它们使用不同的通信协议,数据格式或语言,甚至是完全不同的体系结构。与简单传达信息的网桥不同,网关重新打包它们收到的信息以满足预期系统的需要。那么网关和路由器之间的区别是什么? 网关和路由器之间的区别如下: 路由器的作用是连接不同的网络并传输信息。根据用途,可分为:接入,企业级,骨干级,太比特,多WAN和3G无线等。 网关 网关可以是路由器,交换机或PC。对于同一网段内的通信,不必涉及网关。只有当主机和非本地网段设备通信时,才需要将所有数据包发送到网关设备,然后通过网关设备转发或路由它们。 路由器是一个网络层系统。一般来说,市场上的路由器分为两类,一类是单协议路由器,另一类是多协议路由器。路由器可以转换数据格式,成为与协议不同的网络互连的必要设备。 网关与路由的关系可以表示为:网关是网络连接的基础,路由是网络连接的桥梁。 路由器使用静态或动态路由来确定网络之间的最短路径。静态路由需要管理员手动设置,动态路由USES协议以动态发现网络之间的路径并确定最短路径。通常,静态路由用于小型网络,动态路由用于大型复杂网络。 现在,路由器集成了网关功能,因此路由器也具有网关功能。 网关和路由器之间的区别 从网关和路由器的定义来看,如果只连接两个网络,则只需要一个网关。 假设只有两个网络:网络A和网络B. 为了使网络A和网络B能够通信,只使用网关连接两个网络,因为只有两个网络,并且不需要确定网络之间的最短路径。 如果需要连接多个网络,为了确保网络的可靠性,需要将网络结构设计为完整网络或部分网络。通过这种方式,网络之间的通信需要两个设备,网关和路由器。由于当前路由器集成了网关的功能,因此只能使用一个设备路由器。
