Interpretation of scheme topology diagram
In this carefully designed topology diagram, we can see that the network topology structure of the new energy solar thermal power plant has been comprehensively displayed. The core part is a large industrial Ethernet switch with network management, which undertakes the core switching task of the entire network. This switch adopts an IP40 protective casing, ensuring its stable operation in harsh industrial environments. Industrial grade EMC design ensures communication stability by protecting it from electromagnetic interference.
It is worth noting that this network supports RSTP and CK ring technologies for achieving Ethernet redundancy and ring self-healing. This means that even if a node in the network fails, communication can be quickly restored through ring network self-healing technology, with a self-healing time of less than 20ms, greatly improving the reliability of the network.
In addition, the display screen in the upper right corner displays real-time network status information, providing administrators with intuitive monitoring methods. The "CK Ring Network" mark in the bottom left corner is a prominent identification of the unique technology of the network.
5、 Product features detailed
1. Protection and design: The industrial Ethernet switch with network management has an IP40 protective shell, which can effectively resist the invasion of dust and foreign objects in the external environment. Meanwhile, the industrial grade EMC design enables it to maintain stable performance in various electromagnetic environments.
2. Power and temperature adaptability: The switch supports a wide range of redundant power inputs (12-48V DC), ensuring the reliability of network communication in the event of power fluctuations or failures. The fanless, low-power design, and a wide temperature range of -40~85 ℃ can meet various industrial requirements and provide a convenient Ethernet communication solution.
3. Redundancy and self-healing: Supports RSTP and CK ring technologies, allowing the network to quickly self heal in the event of a failure. The self-healing time of the ring network is less than 20ms, greatly improving the availability and stability of the network.
4. Alarm function: The switch supports relay alarm output. Once there is an abnormality in the power supply, port, or ring network status, it can immediately send an alarm signal, making it easy for administrators to detect and handle problems in a timely manner.
5. Ring network technology: Supports plug and play redundant self-healing Ethernet ring network technology (fault recovery time under full load<20ms), not only supporting single ring mode, but also supporting multiple ring network modes such as tangent and intersection, providing flexible and versatile network solutions for new energy solar thermal power plants.
