方案拓撲圖解讀
在這張精心設計的方案拓撲圖中，我們可以看到新能源光熱發(fā)電廠的網絡拓撲結構得到了全面的展示。核心部分是一個大型的網管型工業(yè)以太網交換機，它承擔著整個網絡的核心交換任務。這臺交換機采用了IP40防護外殼，確保了其在惡劣工業(yè)環(huán)境下的穩(wěn)定運行。工業(yè)級EMC設計，使其免受電磁干擾的影響，從而保證了通訊的穩(wěn)定性。
值得注意的是，這個網絡支持RSTP和CK-ring技術，用于實現以太網的冗余和環(huán)網自愈。這意味著即使在網絡中某個節(jié)點出現故障，也能通過環(huán)網自愈技術迅速恢復通訊，自愈時間小于20ms，極大地提高了網絡的可靠性。
此外，右上角的那塊顯示屏幕實時展示著網絡狀態(tài)信息，為管理員提供了直觀的監(jiān)控手段。而左下角的“CK-Ring環(huán)網”標記，則是對該網絡特色技術的醒目標識。
五、產品特點詳述
1.防護與設計：網管型工業(yè)以太網交換機具備IP40防護外殼，能有效抵御外界環(huán)境中的塵埃和異物侵入。同時，工業(yè)級EMC設計使其在各種電磁環(huán)境下都能保持穩(wěn)定的性能。
2.電源與溫度適應性：交換機支持寬范圍冗余電源輸入（12~48V DC），確保了在電源波動或故障時，網絡通訊的可靠性。無風扇、低功耗的設計，以及-40～85℃的寬溫度工作范圍，能夠滿足各種工業(yè)的要求，提供便捷的以太網通訊解決方案。
3.冗余與自愈：支持RSTP和CK-ring技術，使得網絡在出現故障時能夠迅速自愈，環(huán)網自愈時間小于20ms，極大地提高了網絡的可用性和穩(wěn)定性。
4.告警功能：交換機支持繼電器告警輸出，一旦發(fā)生電源、端口或環(huán)網狀態(tài)異常，能夠立即發(fā)出告警信號，便于管理員及時發(fā)現并處理問題。
5.環(huán)網技術：支持即插即用的冗余自愈以太環(huán)網技術（全負載下故障恢復時間＜20ms），不僅支持單環(huán)模式，還支持相切和相交等多種環(huán)網模式，為新能源光熱發(fā)電廠提供了靈活多變的網絡解決方案。
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.
