In the IIoT field, secure communication is a key element to ensure production efficiency, data security and stable operation of the system. As a bridge connecting the physical world and the digital world, the choice of explosion-proof industrial routers is particularly critical. This article will help you make a wise choice from multiple dimensions such as application requirements, hardware performance, stability, and security. 

1. Clarify application requirements: 

Demand-oriented, precise selection of different application scenarios have different requirements for explosion-proof industrial routers. Before purchasing, it is necessary to understand the specific requirements of the application in detail, such as bandwidth, latency, connection stability, and whether explosion-proof rating is required. For example, video surveillance requires high-bandwidth, low-latency routers to ensure real-time data transmission; Big data transmission focuses more on throughput and stability. In addition, if there are explosive gases or vapors in the application scenario, the explosion-proof rating such as Ex d ⅡC T6 Gb will become a must to ensure the safe operation of the equipment in extreme environments. 

2. Hardware performance: 

Strong performance and worry-free transmission. Hardware performance is the core of explosion-proof industrial routers, directly affecting their transmission speed, stability, and reliability. The following are some key performance indicators: 

● Processor performance: High-performance processors can support more device connections and higher data transmission rates, such as dual-core processors using the MIPS architecture. 

● Number of network interfaces: Ensure that the router can meet the needs of existing devices and future expansion, and the multi-WAN port design can enhance the flexibility and reliability of network connectivity. 

● Dustproof and waterproof rating: The industrial environment is complex and changeable, and a dustproof and waterproof rating such as IP68 can effectively ensure the stable operation of equipment in harsh environments. 

3. Stability: 

With a consistent online presence and worry-free operation, stability is an essential attribute of explosion-proof industrial routers. In harsh industrial environments, such as high temperature, high humidity, vibration, etc., routers must have high stability and reliability. 

The following are some key measures to improve stability: 

Redundancy design: 

such as dual SIM card redundancy backup function, when one SIM card fails, it can automatically switch to another one to ensure that the network is never disconnected. Hardware-level watchdog: fault self-detection and self-repair functions ensure system stability.

Heat dissipation performance:

Good heat dissipation performance can ensure the router to operate stably for a long time in high temperature environment. 

4. Safety: Multiple protection measures ensure data security. 

In industrial networks, data security and privacy are of utmost importance. When purchasing, it is necessary to choose a router with strong security features, such as 

● Data encryption: Support for SSL/TLS, IPSec, AES, and other encryption protocols to ensure the security of data transmission. 

● Firewall: Built-in firewall functions such as NAT, blacklist and whitelist access restrictions to prevent unauthorized access. 

● Identity authentication and access control: Support multiple authentication methods such as username/password authentication, two-factor authentication, and fine-grained access control policies to ensure that only authorized users and devices can access the network. 

● Intrusion detection system (IDS): monitor network traffic in real time, detect and prevent potential attacks. 

5. Scalability and management maintenance: flexible configuration, easy to manage 

As the Industrial Internet of Things develops, new devices and functions may need to be added in the future. Therefore, it is necessary to choose a router with good scalability so that new devices and functions can be easily added in the future. At the same time, the management and maintenance of the router is also an important factor to consider when purchasing: 

● Interface type: Ensure that the router supports the protocols commonly used in industrial communication and has a rich variety of interface types to facilitate the connection of various industrial devices and sensors. 

● Remote management: Supporting multiple platform management modes such as SSH, Telnet, and Web, facilitating remote configuration, monitoring, and troubleshooting. 

● Software upgrade and maintenance: consider whether the router supports firmware online upgrade and whether the manufacturer provides long-term technical support and software update services. 

6. Brand and reputation: Choose a brand that you trust and has a good reputation

Quality assurance is also an important factor when shopping. Choosing a well-known brand and understanding the user evaluation and feedback of the product can help to purchase an explosion-proof industrial router with stable performance and high-quality service. At the same time, the technical support of the manufacturer is also very important. A company that can provide timely technical support, respond quickly to customers, and solve problems is more reliable. 

7. Price and budget: reasonable investment, cost performance is king

When purchasing, it is also necessary to choose suitable equipment based on your actual needs and budget. Don't just pursue low prices and ignore the quality and performance of the equipment, otherwise it may bring greater risks and losses. Reasonable investment and selection of cost-effective products can ensure long-term stable operation and reduce maintenance costs. The selection of an explosion-proof industrial router is a systematic project that requires comprehensive consideration from multiple aspects such as application requirements, hardware performance, stability, security, scalability, management and maintenance, and price. By selecting the appropriate explosion-proof industrial router and taking corresponding safety measures, network security can be strengthened to ensure the stable operation of the industrial network.
