With the advent of the industrial 4.0 era, the connection between industrial control systems and the Internet has become increasingly close, and the problem of network security has become increasingly prominent.In this context, the role of Cellular Router is particularly important.To ensure that its quality and performance are up to standard, we need to qualify the Cellular Router.In this article, we will discuss the quality evaluation criteria of Cellular Router.
I. Hardware performance
Stability: The industrial environment often has harsh conditions such as electromagnetic interference, high temperature and high humidity.Therefore, the hardware of the router must be able to withstand these challenges and ensure stable operation for a long time.
Processing capability: Considering the real-time requirement of industrial data transmission, the router shall have powerful data processing capability.To ensure fast packet forwarding and low latency.
Interface richness: In order to meet the connection requirements with various industrial devices, the router should have multiple interfaces.Uch as Ethernet, serial port, wireless, etc.
Protection capability: The hardware shall be equipped with electromagnetic shielding, anti-surge and other protective measures to reduce the impact of external interference on the equipment.
II. Software function
Security: The router should have security features such as firewall, VPN, intrusion detection and prevention to prevent external attacks.
Real-time: In order to meet the requirements of industrial applications, the router software should have the characteristics of real-time operating system.Ensure the timeliness of data processing.
Configurability: The user shall be able to flexibly configure the router according to actual requirements, such as network parameters, routing strategies, etc.
Remote management: Provide remote management function, so that users can easily monitor and maintain the router.
III. Network security performance
Encryption technology: The router shall support multiple encryption technologies to ensure the confidentiality and integrity of data.
Authentication mechanism: Provide complete user and device authentication mechanism to prevent unauthorized access.
Access control: Support fine-grained access control policies to ensure the safe use of network resources.
Logging and auditing: Logging the operations of the router so that security issues can be tracked and audited.
IV. Environmental Adaptability
Temperature range: The router should work well in a wide temperature range to adapt to various industrial environments.
Resistance to vibration and shock: The router shall be resistant to vibration and shock to accommodate the mechanical stresses that may exist in the industrial field.
Protection grade: according to different industrial environments, the router shall have corresponding protection grade, such as dustproof, waterproof, etc.
V. Maintenance and Support
After-sales service: The supplier shall provide perfect after-sales service, including technical support, maintenance, etc.
Software updates: Vendors should regularly release software updates and security patches to fix possible security issues.
Documentation and training: Provide detailed user manuals and training materials to help users better use and maintain the router.
In view of the above,CellularRouter quality evaluation criteria cover hardware performance, software functions, network security performance, environmental adaptability, maintenance and support, etcFace. These criteria should be considered when selecting and using Cellular RouterTo ensure network security and the smooth progress of industrial production.
