4G Rail Type Industrial Router for Selection Guide

Selection Guide for 4G Rail Type Industrial Router

4G rail type industrial router adopts high-performance industrial-grade 32-bit communication processor and industrial-grade wireless module, with embedded real-time operating system as the software support platform, and provides 1 RS232 (or RS485/RS422) and 4 Ethernet LANs , 1 Ethernet WAN and 1 WIFI interface, which can connect serial device, Ethernet device and WIFI device at the same time, realize data transparent transmission and routing function, support rail or wall-mounted installation.

　　 Selection guide for 4G rail type industrial router:

　　1, brand

　　 brand is a symbol of quality and workmanship. Industrial Internet of Things is a relatively young industry, unlike other industries that have a history of a hundred years, brand communication has reached the level of household names. The formation of an industrial Internet of Things brand is nothing more than word-of-mouth. Through third-party evaluations such as the purchase evaluations of friends around you or the evaluations of search engines and purchase platforms, you can clearly understand how the brand is.

　　2, stability

　　Industrial rail buckle: The shaking of the transmission equipment will affect the stability of data transmission, and there is no such hidden danger if it is fixed on the transmission equipment. The 4G industrial router with rail buckle is easy to install at will, simple and stable.

　　 Large memory: The function of memory is to receive data packets while alleviating the data sent by the user. It is necessary to ensure stable transmission and data packets are not lost. Large memory is the biggest helper;

　　Metal sheet metal material: shielding electromagnetic interference, anti-radiation, while improving the safety isolation coefficient, among which the lightning protection design is particularly suitable for industrial projects with harsh environments;

　　 Circuit protection: EMC industrial design protection, ESD (interface) anti-static design, EFT anti-pulse. The PCB is produced with high-quality materials to ensure the stability of the board from the hardware, plus the circuit protection industrial design, the circuit transmission system is stable and reliable;

　　3, safety

　　 Security to ensure that data is stable and orderly during transmission is one of the important technical indicators for evaluating 4G industrial routers.

　　(1) APV/VPN

　　 Most 4G industrial routers are equipped with APV/VPN security tunnels, and data transmission through dedicated tunnels is more secure. The data transmission of dedicated industrial routers all have VPN function. There are many VPN transmission protocols. Among them, PPTP and L2TP are very commonly used. Other transmission protocols are relatively unpopular, and they are only used for items with special requirements. Therefore, when there is no special requirement, it is not necessary to prepare a VPN of multiple protocols.

　　(2) Firewall

The firewall is a security barrier between the local area network and the wide area network. Through the basic settings of the firewall, it can block some internal network IP addresses, freely set IP addresses and filter communication ports, etc. The most important thing is to prevent hacker attacks and virus intrusion. , It is an important guarantee for the safe transmission of data. If any 4G industrial router does not have a firewall, you can basically give up the choice.

　　(3) Watchdog protection

　　 The watchdog protection function uses a timer to monitor the operation of the main program. When the MCU is working normally, it outputs a signal at regular intervals. This process is called feeding the dog.

　　 Watchdog protection is mainly to provide safety protection functions for projects that need to operate continuously for a long time to avoid crashes. When a problem occurs in the system, it can quickly return to normal working conditions.

　　 4. Scope of application

　　The scope of application of industrial routers According to the requirements of the project, it is sufficient to select 4G industrial routers with matching parameters. For example, in the outdoor industrial project in the Northeast, the winter temperature in the Northeast is about minus 20°C-30°C. Normal operation at this temperature needs to choose a 4G industrial router with a wide temperature range.

　　 If the 4G industrial wireless router is used in the intelligent public transportation system, and the data transmission speed and interface requirements are relatively high, then choose the equipment with high transmission speed requirements.

　　 5. Operator selection

　　From the operator's point of view, the five-mode 12-band industrial router is usually suitable for most projects.

　　6, the amount of belt machine selection

　　The choice of the amount of computers is mainly based on the actual scale of the project and the number of Internet-connected devices. Usually in the environment of a shopping mall, there are many access devices, so you need to choose a router with a higher amount of equipment. If it is not a special requirement, 24 wireless intervention devices can satisfy most industrial projects.
