Functional composition of 4G industrial gateway

文章目录 : 技术相关

The basic function of the 4G industrial gateway is to connect the two heterogeneous networks, which is particularly common in the industrial Internet of things scenario, because the sensor network often USES completely different electrical signals and protocols from the common network layer (long distance transmission network).

 

4G industrial gateway functional composition

 

Sensing layer signal interface

It is mainly responsible for the task of docking the signals of various devices in the sensor network. The module includes a hardware interface for docking different electrical signals, as well as corresponding data acquisition and instruction sending software. In order to deal with the complexity of the perception layer, manufacturers of industrial gateways will equip a hardware interface and protocol combination of the signal interface of the perception layer according to their target application domain.

 

Network layer signal interface

It mainly undertakes the task of docking the signals of the network layer. Compared with the perception-layer signal interface, the network layer signal interface is generally much simpler, because usually the whole system only needs a standard long-haul network and its protocol, so the corresponding hardware interface and data transceiver software are relatively simple. However, this is not to say that it can only support one type. In practical applications, manufacturers of industrial gateways are often designed to support multiple forms of long-haul networks for product universality. The specific form can be the way that multiple interfaces are equipped at the same time, or the product can be designed in the form that plug-in CARDS can be configured, so that users can choose different configurations to be configured when leaving the factory.

 

The data processing

The data processing on the device side mainly solves the problem of data mismatch. That is, the range, frequency, integrity, and so on of the data needed by the server. The purpose of data processing is to sort the data from the input interface, transform it into a suitable data form for output and push it to the output interface. The input and output sides can be played by either the device side or the server side, so the flow of data is bidirectional and different depending on the type of data.

 

In-place database

The processed data also needs to be stored in the gateway local database in some scenarios for complex data processing processes or other in-place business logic processing. Because industrial gateway generally belongs to embedded computing device, so this kind of database also generally adopts embedded database. The function of embedded database is simple, and it has memory buffer to improve the access speed.

 

Local business logic

It mainly deals with the business logic of the local systems related to the devices, sensors and actuators connected by the part of sensor network associated with the gateway. The richness and complexity of local business logic modules of different gateways vary greatly. If there is no such functional module in an industrial gateway, it is often called a data transmission gateway, or a protocol converter or communication manager. For a detailed description of in-place business logic, see edge computing.

 

Other features

In addition to the main modules above, a gateway also often configures its functional user interface, either with buttons, a command line (via Telnet or a serial port), or a graphical interface (such as a built-in WEB Server or even a panel). If the gateway has in-place business logic, it may also need tools to load the script files, configuration files, and so on that are required by the local business logic.

As a remote device, self-maintenance of 4G industrial gateway is also very important. In general, it is required to make use of the advantages of its own connection to the server to automatically download its own software update package from the server and complete the update. Some Settings and configuration work should also be completed through remote login, so as to reduce the cost of on-site maintenance of dispatched personnel and improve the response speed to user needs.

The difference between a gateway and a router

文章目录 : 产品文章, 技术相关

A gateway is a computer system or device that ACTS as a transformation agent. A gateway is a translator between two systems that use different communication protocols, data formats, or languages, or even completely different architectures. Unlike Bridges that simply convey information, gateways repackage the information they receive to suit the needs of the intended system. So what’s the difference between a gateway and a router?

 

The differences between a gateway and a router are as follows:

 

The role of a router is to connect different networks and transmit information. According to usage, it can be divided into: access, enterprise level, backbone level, terabit, multi-WAN and 3G wireless, etc.

 

The gateway

 

A gateway can be a router, switch, or PC. For communication within the same network segment, it is not necessary to involve the gateway. Only when the host and non-local network segment devices communicate, it is necessary to send all the data packets to the gateway device, and then forward or route them through the gateway device.

 

Router is a network layer system. Generally speaking, routers in the market are divided into two categories, one is single-protocol router, and the other is multi-protocol router. The router can transform the data format and become a necessary device for network interconnection different from protocols.

 

The relationship between gateway and route can be expressed as: gateway is the foundation of network connection, and route is the bridge of network connection.

 

Routers use static or dynamic routing to determine the shortest path between networks. While static routing requires an administrator to set it manually, dynamic routing USES protocols to dynamically discover paths between networks and determine shortest paths. Typically, static routing is used for small networks and dynamic routing is used for large complex networks.

 

Now, routers integrate gateway functionality, so routers also have gateway functionality.

 

The difference between a gateway and a router

From the definition of gateway and router, if you simply connect two networks, you only need a gateway.

Suppose there are only two networks: network A and network B

To enable network A and network B to communicate, only use the gateway to connect the two networks, because there are only two networks, and do not need to determine the shortest path between the networks.

 

If multiple networks need to be connected, in order to ensure the reliability of the network, the network structure needs to be designed as a full network or a partial network. In this way, two devices, gateway and router, are needed for the communication between networks. Because the current router integrates the functions of the gateway, only one device, router, can be used.

The E-Lins H685 series 4G router with Ethernet is a compact, ruggedized 3G/4G/LTE cellular networking solution designed for mission-critical connectivity in the most challenging environments.

VPN在工业,商业和民用领域非常受欢迎。它们可以使网络传输更安全,更专业,更自由。工业VPN路由器的分类工业VPN路由器的常见分类是PPTP,L2TP,IPSEC。最常见的是PPTP协议。如上所述,市场上的大多数工业路由器都具有PPTP安全协议,即点对点隧道协议。使远程用户能够通过拨入ISP,直接连接到Internet或通过其他网络安全地访问企业网络。 L2TP是一种行业标准的VPN网络传输隧道协议,在功能上类似于PPTP协议。例如,它还可以加密网络数据流。

区别在于PPTP使用单个隧道,L2TP使用多个隧道。 L2TP提供数据包头压缩和隧道验证,而PPTP则不提供。 IPSEC安全协议通过端到端安全提供主动保护和防止攻击,端到端安全是安全网络的长期方向。在通信中,只有发送方和接收方是唯一知道IPSEC保护的计算机。 IPSec安全服务需要支持共享密钥以进行身份​​验证和机密性,并且需要手动输入密钥。如何设置工业VPN路由器不同品牌的工业VPN路由器有不同的设置,因为设置和内置网页设置都是由厂家制作的。但功能相同,设置大致相同。

Why would industrial routers set up VPN capabilities

文章目录 : 产品文章

Industrial router is the industrial version added on the basis of ordinary router, while industrial VPN router is the VPN function added on the basis of industrial router. VPN generally refers to a virtual private network, which is simply a private network established on a public network for encrypted communication. VPN function is to achieve the target address conversion and remote access while encrypting the packet. Therefore, the industrial VPN router is very suitable for the data transmission security requirements of the project. Why would an industrial router set up a VPN function? So what are the benefits of the VPN feature?

VPN industrial router

VPNS allow you to work in a complex public network without worrying about security. Of course, this is also the basic function of industrial VPN routers;

2. It can solve the problem of networking with multiple devices at the same time and using the VPN function at any time. No more tedious operation after login and connection of each device is needed. As long as you switch a network, you can choose to use or not to use VPN function to achieve the effect of out-of-the-box;

3, a number of connected devices networking, some need to use local network, some use VPN network, so you can stagger the use of;

4. The industrial VPN router can connect multiple terminals with one account, no longer having to worry that the VPN account will limit the number of connected terminals;

Industrial router

5. Most of the industrial routers on the market have already supported the PPTP connection mode in the VPN, and the foolproof operation Settings are no longer the patent of the experts.

VPNS are very popular in industrial, commercial and civil applications. They can make network transmission more secure, professional and free. Classification of industrial VPN routers common classification of industrial VPN routers are PPTP, L2TP, IPSEC. The most common one is PPTP protocol. As mentioned above, most industrial routers on the market have PPTP security protocol, namely point-to-point tunnel protocol. Enables remote users to safely access the enterprise network through dialing into an ISP, through a direct connection to the Internet, or over other networks. L2TP is an industry standard VPN network transmission tunnel protocol, which is similar to the PPTP protocol in function. For example, it can also encrypt network data streams.

The difference is that PPTP USES a single tunnel and L2TP USES multiple tunnels. L2TP provides packet head compression and tunnel validation, while PPTP does not. IPSEC security protocol provides active protection and prevention of attacks through end-to-end security, which is the long-term direction of secure networking. In communications, only the sender and receiver are the only computers that are aware of IPSEC protection. IPSec security services require support for Shared keys for authentication and confidentiality, and require manual key entry. How to set up an industrial VPN router different brands of industrial VPN routers have different Settings, because the Settings and built-in web page Settings are made by the manufacturer. But the functionality is the same, and the setup is much the same.

The E-Lins H685 series 4G router with Ethernet is a compact, ruggedized 3G/4G/LTE cellular networking solution designed for mission-critical connectivity in the most challenging environments. It is qualified for M2M (Machine to Machine), IoT (Internet of Things) and In-Vehicle applications. Super mini size suitable for embedding applications.

In addition to the robustness, reliability, security, friendly-using, the H685 4G router with Ethernet is competent to be engineered to protect against extreme temperatures, humidity, shocks, vibrations, dust, reverse polarity, and transient voltage, which is widely used in more than twenty industrial fields, such as CCTV security surveillance, AMR, vehicle, retails, vending machines, power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other fields.

告别SIM卡,eSIM时代到来!

Industrial-grade wireless routers

As an industrial-grade router, the industrial-grade 4G router is more powerful than the ordinary household router in many aspects. Generally speaking, the well-known industrial-grade 4G router has the following advantages in the use process.

 

1. High stability

One of the major advantages of industrial-grade 4G routers is their high stability in data transmission and reception. It USES high performance industrial-grade wireless modules and industrial-grade high stability and high precision components, so that it can resist outdoor harsh environment without data transmission interruption or loss.

 

 

 

2. Fast data transmission and processing

 

 

Compared with ordinary routers, industrial-grade 4G routers use high-performance CPU processors, so they can transmit and process data several times faster than ordinary routers. They can satisfy more people to connect to the network at the same time, and the transmission distance is longer and the coverage is larger.

 

 

 

3. Powerful functions

 

 

Advanced industrial-grade 4G routers have more powerful functions than ordinary routers. For the average home router, the function is simple as long as it can connect to the network normally. But for industrial control industry, routers need more functions to run normally. Industrial-grade 4G routers have corresponding functions to meet the needs of different fields. If other special functions are needed, you can also choose customized products.

 

 

 

The main advantages of the industrial-grade 4G router are its high stability, fast data processing speed and powerful functions. In addition, the number of ports it provides and the strong wireless signal receiving ability are also its own advantages. Because industrial-grade 4G routers are often used in high-end fields or in complex outdoor conditions, they must have more functions and advantages to meet people’s needs.

Industry level SMS cat is based on mobile GSM/GPRS network platform, embedded with industry level GSM/GPRS wireless module SMS and Internet devices. Modems are essential to computer networking, and because routers are often used with modems, many people confuse them. So, what are the differences between modems and routers?

 

Industrial MODEM is a modular product specially developed for remote control, remote data acquisition system and remote distributed control system. It is similar in shape to the size of business card, and is easy to connect with the user board.

 

 

What are the differences between industrial modems and routers

 

 

1. Different functions

 

Modem is a necessary equipment of computer networking, a dial-up modem computer can, and the router is a way to help multiple computers share a network device, with the help of the router, several computers can be in the same Internet line access to the Internet, however, necessary equipment of the router is not the Internet, no router, the computer can still connected to the Internet through modem.

 

 

2. Different connection modes

 

Due to the different functions, the two are connected in different ways. One end of a modem is connected to a telephone line, and the other end is connected to a computer or a router.

 

 

3. Different appearance

 

The modem has a simple shape, like a flat rectangular box, which is very small, while the router has a variety of shapes, including rectangular shape and oval shape, with a larger volume than the modem on the whole. In addition, the wireless router also has a number of different antenna devices.

 

4. Different ports

 

Modems generally have only two ports, one for the phone line and one for the Internet, while routers have more ports. Usually, there are five ports, one for the modem, and the rest can be connected to one or more computers at will.

 

Industry modem application:
