Project Introduction With the continuous penetration of the concept of networking and informatization into the automation field, the concept and technology of monitoring automation control are also constantly developing. In the monitoring engineering control system, an integrated full distributed control system based on Industrial Ethernet is adopted, which has a high degree of dispersion, real-time, reliability, openness and interoperability, and can also achieve data, voice and Video "triple play" system.

Network structure The entire water plant monitoring area is ring-shaped, of which the total length is a monitoring length of about 60 km, 18 points are basically distributed at equal distances, and a total of 18 KIEN 5000 switches and optical transceivers are connected to the control center to form a fiber ring. The network is connected to the server of the control center through a twisted pair cable. Each monitoring point is connected to one network video and one PLC control signal. Then manage it through the server. as the picture shows.
If the switch's connection medium fails while the system is operating, the ring structure will switch the network working topology in less than 300ms. Does not affect the work of the entire system, thus ensuring the reliability of the system. And under the same redundancy, the redundant ring network structure not only reduces the concentration of risks, but also reduces the implementation cost. Flexible access to other network switches. Good security features ensure the secure transmission of data.

Network Advantage Analysis The Ethernet solution is based on Layer 2 switching and Layer 3 routing. The advantage of adopting Ethernet as a switching transmission and access platform is obvious. The first is a huge network foundation and long-term experience, and all current popular operating systems and applications are also compatible with Ethernet. Second, Ethernet has a good price/performance ratio, and the initial cost and operating cost are low; Ethernet has good scalability, easy installation, and high reliability. Ethernet access is asynchronous and works well for handling IP burst traffic. At present, after Ethernet switches from shared media to full-duplex LAN switching, information isolation between computers is implemented to a certain extent, link bandwidth competition and potential collision opportunities are eliminated, and the transmission distance of Ethernet is also greatly improved. Extensions.
Recently, Ethernet has gradually expanded to metropolitan area networks and even wide area networks. From a technical point of view, Ethernet is a very simple solution that requires only a minimal amount of planning, design, and testing. It has been used for years and is familiar to users. The time for business assignment can be reduced to hours or days. Second, Ethernet is a standard technology with good interoperability, extensive hardware and software support, and low cost. It has been predicted that in metropolitan area networks and wide area networks, Ethernet costs may be 25% and 10% of SDH and ATM; Finally, Ethernet is a media-independent bearer technology that can be transparently connected with copper pairs, cables, and various optical fibers. Different transmission media interfaces are used to avoid the cost of rewiring. From a structural point of view, Ethernet is emerging as an unprecedented end-to-end solution, eliminating format changes at the network boundaries that are essential for other solutions, reducing network complexity. At the same time, Ethernet is a very scalable solution that can scale from 10Mbits/s, 100Mbits/s, 1Gbits/s to 10Gbit/s. From a management point of view, network management can be greatly simplified because the same system can be applied at all levels of the network.

To sum up, we have selected Dongti Telecom's two-tier switched industrial Ethernet switch KIEN 5000 and optical transceivers to form an industrial-grade redundant ring network.


The KIEN5000 industrial Ethernet switch device features industrial-grade components and is specially designed to ensure high product reliability.
It can work stably in extreme temperature range and can adapt to the harsh working environment on the industrial site.
This product network is very flexible, can form a super fiber self-healing ring network, super Ethernet self-healing ring network, to facilitate the use of the user.
The redundant 10/100 Mbit/s twisted-pair ports use the uplink redundancy interface to form a self-healing ring network. Improve system reliability.
It has advanced self-healing function to solve the loop. When a fault occurs somewhere in the ring network, the communication data can be quickly switched to the backup network to ensure normal network communication and the self-healing time is less than 300ms.
Supports electrical port auto-negotiation function, no configuration is required, and can be automatically consistent with the electrical outlet setting at the opposite end.
With WEB-based KIEN network management system, powerful, easy to manage and maintain.
Supports virtual network (VLAN) standards to control broadcast domain and segment traffic, which can improve network performance, security, and manageability.
The sturdy and delicate shape design has a certain degree of protection.
The product provides a variety of installation methods, such as rail type, wall-mounted, etc., suitable for different installation conditions.
The above are the basic characteristics of the product. If we allow self-healing rings to be built under the condition that the optical fiber cable is allowed to be installed, it will not only save equipment capital costs, but also maximize the advantages of the network high reliability of the equipment.
