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。

Step 6) Set Cell SIM2. Follow Step 6 of setting Cell SIM1.

Step 7) Activate the “Cell SIM Switching Trigger” feature

Setting location: H750 web: Internet Settings – WAN — All Cell Option

There are 6 types of Cell Option Mode (Cell Switching Mode),

Mode Description
cell1 only With this mode, only sim1 works
cell2 only With this mode, only sim2 works
fail switch cell1 first With this mode, it works as below,
sim1 on – switch to sim2 on if sim1 failed, and keep working on sim2 – switch to sim1 on if sim2 failed, and keep working on sim1 –switch to sim2 on if sim1 failed, and keep working on sim2 – “cycling”
fail switch cell2 first With this mode, it works as below,
sim2 on – switch to sim1 on if sim2 failed, and keep working on sim1 – switch to sim2 on if sim1 failed, and keep working on sim2 –switch to sim1 on if sim2 failed, and keep working on sim1 – “cycling”
cell1 prefer With this mode, it works as below,
sim1 on – keep working on sim1 – if sim1 failed, switch to sim2 – keep working on sim2 for “Check Time (for Prefer mode)”, then try to check if sim1 is restored, if restored, switch to sim1 – “cycling”
cell2 prefer With this mode, it works as below,
sim2 on – keep working on sim2 – if sim1 failed, switch to sim1 – keep working on sim1 for “Check Time (for Prefer mode)”, then try to check if sim2 is restored, if restored, switch to sim2 – “cycling”
advance data traffic cell1 first With this mode, it works as below,
sim1 and sim2 have data limits. Sim1 on — once sim1 data count reaches the limitation, switch to sim2 — once sim2 data count reaches the limitation, sim1 and sim2 neither works until next day/week/month.With this mode, users need set the “Advance Cell Traffic” configuration
advance data traffic cell2 first With this mode, it works as below,
sim1 and sim2 have data limits. Sim2 on — once sim2 data count reaches the limitation, switch to sim1 — once sim1 data count reaches the limitation, sim1 and sim2 neither works until next day/week/month.With this mode, users need set the “Advance Cell Traffic” configuration. Refer to the detailed manuals from E-Lins.
cell on time traffic Sim1 and sim2 work according the time period schedule settings.

With this mode, users need set the “Advance Cell Traffic” configuration. Refer to the detailed manuals from E-Lins.

Notes: Sometimes it may happen the following,
1) Choosing ” fail switch cell1 first” or “cell1 prefer”, SIM2 is firstly online, this is not problem because sometimes the SIM1 has some problem to be online.

2) Choosing ” fail switch cell2 first” or “cell2 prefer”, SIM1 is firstly online, this is not problem because sometimes the SIM2 has some problem to be online.

Check Time (for Prefer mode): set the time for “cell1 prefer mode” or “cell2 prefer mode”

Description for Check Time (for Prefer mode):
For example1, Cell Option Mode is “cell1 prefer”, and Check Time (for Prefer mode) is “5” minutes. It works as below,
Router works with sim1 firstly — if sim1 failed, switch to sim2 — keep working on sim2 with 5 minutes — after 5 minutes, check if sim1 is ok, if ok, switch back to sim1.

For example2, Cell Option Mode is “cell2 prefer”, and Check Time (for Prefer mode) is “5” minutes. It works as below,
Router works with sim2 firstly — if sim2 failed, switch to sim1 — keep working on sim1 with 5 minutes — after 5 minutes, check if sim2 is ok, if ok, switch back to sim1.

Step 8) Click “View” button to double check if the settings are correct.

Step 9) Click “Apply” button or Re-power the router to reboot. Then H750 router will reboot and dialup online.

Once it’s online, the CELL LED will light on.
Notes: sometimes the router cannot dialup after the APN configuration, please power off the router, and re-power on it. Because some radio modules need reboot after the initial APN configuration.

Step 10) Once H750 router is online, it gets a WAN IP Address and Status Page will show similar info.

Step 11) Activate the “Cell ICMP Check” feature

Setting location: H750 web: Internet Settings – Cell ICMP Check

Notes:

1) For router working with best stability, we highly suggest activate and use this feature.

With this feature, the Router will automatically detect its working status and fix the problem.

2) Please disable the “Ping from WAN Filter” if use ICMP check feature, otherwise it cannot work.

 

  • Active: tick it to enable ICMP check feature
  • Check method: fill in checking domain name or IP. Click HOST/IP check button to verify before using it.
  • Check interval time (sec): set the interval time of every check
  • Check Count: set the checking count number
  • Reboot Count Before Sleep: H750 Router will sleep to stop checking after failed with set times.
  • Sleep Time (min): H750 Router sleep timing before resume check.

 

Example with above picture:

H750 Router check “www.google.com” and “112.134.8.8”, it will check 3 times. After the previous check, it will do next check after 60 seconds. Totally it will check 3 times. If 3 times all failed, H750 Router will reboot. If reboots 3 times continuously, H750 Router goes to sleep to stop checking. The sleep time is 5 minutes. After 5 minutes, H750 Router resumes to cycle the checking.

 

High Gain Antenna–Yagi-Uda Antenna

Category : 产品文章, 伊林思产品FAQ, 其他

Today, we are talking about high gain antennas. Here I want to introduce a strong one. A Yagi–Uda antenna, commonly known as a Yagi antenna, is a directional antenna consisting of multiple parallel elements in a line, usually half-wave dipoles made of metal rods.

Yagi–Uda antennas consist of a single driven element connected to the transmitter or receiver with a transmission line, and additional “parasitic elements” which are not connected to the transmitter or receiver: a so-called reflector and one or more directors.

The Yagi–Uda antenna consists of a number of parallel thin rod elements in a line, usually half-wave long, typically supported on a perpendicular crossbar or “boom” along their centers. There is a single driven element driven in the center (consisting of two rods each connected to one side of the transmission line), and a variable number of parasitic elements, a single reflector on one side and optionally one or more directors on the other side. The parasitic elements are not electrically connected to the transmitter or receiver, and serve as passive radiators, reradiating the radio waves to modify the radiation pattern. Typical spacings between elements vary from about  110 to ¼ of a wavelength, depending on the specific design. The directors are slightly shorter than the driven element, while the reflector(s) are slightly longer. The radiation pattern is unidirectional, with the main lobe along the axis perpendicular to the elements in the plane of the elements, off the end with the directors.

It’s also a good choice for you when you use E-Lins routers in rural area. This antenna will gain better reception than standard antennas for routers.
