Speaking of home routers, everyone must have a certain knowledge and understanding of this type of product, but when it comes to 4G industrial routers, I believe that not many friends know or have seen 4G industrial-grade routers. So what exactly is an industrial router? How is it different from the router we use at home?
For this reason, I searched on Baidu: It turns out that 4G industrial router is actually a product that uses public wireless networks to provide users with wireless data transmission functions. This is just like how we use mobile phone data to transfer things to another person. A mobile phone or computer has the same principle, but the usage is a little different. Due to design reasons, the product is mainly used in areas with harsher environments to provide various network supports for everyone. Currently, 4G industrial routers have been widely used in things. M2M industry in the Internet industry chain. Such as smart grid, smart transportation, smart home, financial IoT wireless communication router, mobile POS terminal, supply chain automation, industrial automation, smart building, fire protection, public security, environmental protection, meteorology, digital medical care, remote sensing survey, Agriculture, forestry, water affairs, coal mining, petrochemical and other fields.
The product I want to share with you today is the 4G industrial router R300A from Dandelion. The biggest feature of this router for industrial scenarios is that it adds a 4G network communication module on the basis of an intelligent networking router. , thereby realizing wireless hotspot provision and 4G wired dual backup network functions, making up for the lack of full coverage of the wired network, and ensuring the stability and smoothness of the network in all aspects.
A family portrait of the Dandelion 4G industrial router R300A, which includes the host, WiFi antenna, 4G antenna, power adapter, screw package, product manual, and the IoT card shown above.
As we all know, the industrial environment is no better than at home, so the product shell is made of SECC galvanized steel plate material, which is anti-fall, wear-resistant, corrosion-resistant, anti-magnetic, anti-surge and anti-static, and can be used in extreme temperatures of -20 -70 It works stably under the humidity of 10~90RH, and the protection level can reach IP30. It can easily cope with harsh environments.
The display panel of Dandelion 4G industrial router R300A is the system status light, WiFi wireless signal light, and 4G network indicator light. The three-segment signal indication will light up according to the different network strength.
In order to facilitate installation and fixation, Dandelion 4G industrial router R300A not only provides DN35 rail buckles on the back.
There are also removable mounting ears reserved on the side, which can be chosen in a variety of ways. It can be said that it provides great convenience for installation and construction.
In terms of interfaces, from left to right on this side are the WiFi antenna interface, SIM card slot, ground wire interface, WPS quick pairing button, RST reset button, and 4G antenna interface.
In order to better distinguish the installation of antennas, 4G antennas and WiFi antennas have corresponding logos respectively. In terms of these details, I have considered them quite thoughtfully.
The interfaces on the other side of the Dandelion 4G industrial router R300A are still from left to right, including the WAN/LAN interface, LAN interface, power supply terminal interface and 5-36V DC wide voltage power interface. The rich configuration is complete Can meet various usage needs.
Dandelion 4G industrial router R300A supports three Internet access methods: 4G full network access, wired access and wireless relay. Insert the IoT card and turn on the power to enter the standby state. Let’s configure it below explain.
Follow the instructions in the manual, log in to the cloud management platform on the computer, and log in through the SN code or registered account. Note: The SN code of the product is affixed on the packaging box. After entering, set the management password.
The management interface of Dandelion 4G industrial router R300A. If we have networking needs, click I want to network.
The networking process requires two steps. One is to put your Dandelion smart networking devices under the same Oray account, and the other is to set up the smart networking devices under the account in the same smart network. Interconnection can be achieved. Because there was a network established before, I chose to join the existing network.
Enter the ID of the existing network and join the network successfully. The network ID can be found in the property settings of the existing network.
After completing the networking, we can manage the existing network through the Dandelion Cloud Management Platform, including management of equipment, and demand management such as enabling serial port functions. It is worth mentioning that the simple operation The interface is very friendly to managers.
Here comes the key point, the dual backup network configuration of Dandelion 4G industrial router R300A. After logging in, in addition to the Dandelion local management page, we can connect the main network to the Internet through dial-up, and the backup network through 4G. After the network is accidentally disconnected, the router can automatically switch back to the 4G network mode and transmit data through 4G. When the external network is restored, it will automatically switch back to the external network from 4G to ensure the reliability of the network.
In addition to being managed on a computer, the Dandelion 4G industrial router R300A also supports APP control, which facilitates maintenance by managers. They can remotely manage the router through the APP and check the status of the router. As you can see from the picture above, the router has quite complete functions. Like other routers, it has QOS current limiting, blacklist, port mapping and DMZ host functions.
Of course, network management is also possible, and the operation will be simpler than on the computer.
As for signal coverage and strength, it is basically the same as the Huawei router I am currently using, and the stability of the network is also very good. No network disconnection was found during the experience and testing process.
From the above experience, we can see that the Dandelion 4G industrial router R300A is a 4G router with solid workmanship, simple shape, and powerful functions. It has super network backup and networking functions, and flexible installation methods. It is very It is suitable for unattended counters and special industrial scene applications. As a basic equipment for the industrial Internet, it is undoubtedly very qualified.
