In the IIoT application, choosing the right industrial router is the key to ensuring stable device connectivity and secure data transmission. In harsh environments, such as high temperature, low temperature, humidity, vibration, dust and corrosive gases, when selecting an industrial router, the following key factors need to be considered:

1. Environmental adaptability and durability

Dustproof and waterproof rating: Industrial sites are often accompanied by dust, moisture, oil mist, and other adverse factors, so the dustproof and waterproof rating of the router is the primary consideration. High-level protection such as IP30 and above can ensure stable operation of equipment under harsh conditions.
Temperature range: The temperature fluctuation in the industrial field is large, ranging from extremely cold to high temperature. Choosing a router that supports wide temperature operation, such as -20°C to 70°C, can effectively avoid failures caused by extreme temperatures.
Anti-seismic and anti-impact capacity: vibration and impact are inevitable in industrial environment, and the structural design of the router needs to have sufficient anti-seismic and anti-impact capacity to ensure long-term stable operation. The material of the casing should be chosen from high-strength, corrosion-resistant alloys or special plastics to withstand physical damage and chemical erosion.

2. Network Performance and Stability

Bandwidth and throughput: Select the appropriate bandwidth and throughput according to the requirements of the application scenario. For applications such as video surveillance and big data transmission, routers with high bandwidth and low latency are required to ensure real-time data.
Multi-WAN port and load balancing: The multi-WAN port design can enhance the flexibility and reliability of network connections. Through load balancing technology, multiple network links can be utilized simultaneously, improving data transmission efficiency.
Redundant design: Routers that support redundant design such as dual power supplies, dual SIM cards, redundant network interfaces, etc. can quickly switch to the backup link when the primary link fails, ensuring uninterrupted network access.

3. Safety Protection

Data encryption: Industrial data often involves corporate secrets, so routers need to support advanced encryption standards to ensure security during data transmission.
Firewall and VPN: The built-in firewall can effectively prevent external malicious attacks, while the VPN function can enable remote secure access and protect the security boundary during data transmission.
Access control and authentication: Support multiple authentication methods and fine-grained access control policies to ensure that only authorized users and devices can access the network.

4. Flexibility and Scalability

Protocol support: Ensure that the router supports the protocols commonly used in industrial communication to meet the access requirements of different devices.
Interface richness: rich interface types such as Ethernet ports, serial ports, USB, etc., and their quantity, facilitate the connection of various industrial devices and sensors.
Remote management: Industrial routers should have remote management capabilities, such as configuration, monitoring, and troubleshooting through Web interfaces, to reduce on-site maintenance costs.
Modular design: Modular design enables routers to flexibly expand functions according to actual needs, such as adding wireless modules, security modules, and so on.
