Industrial Ethernet switch applications and markets

With the improvement of computer performance and the increase of communication volume, the traditional local area network has more and more exceeded its own load. Switched Ethernet technology came into being. Ethernet is being rapidly applied to various fields of social life, but Ethernet is used. The carrier sense multiplexing collision detection (CSMA / CD mechanism) has poor real-time performance and cannot fully adapt to the real-time requirements of industrial sites. In response to this situation, industrial Ethernet switches came into being.

Industrial Ethernet switches are referred to as industrial switches, and can be applied to real-time Ethernet data transmission in complex industrial environments. Due to various reasons for the on-site environment, what kind of scenarios must be selected for industrial Ethernet switches to be suitable?

Environment with severe electromagnetic interference and extreme temperature

When network equipment is deployed in an industrial site, the stability of ordinary commercial switches will be greatly challenged in the face of a harsh working environment and severe electromagnetic interference. In this regard, industrial Ethernet switches with high reliability, stability, and security have become transmission tools that can adapt to complex industrial environments and facilitate the deployment of industrial automation networks.

Choose a managed or unmanaged switch

If the network is relatively simple, you can use a plug-and-play unmanaged switch; if you want to maintain it in the future, you may need to use a managed type. Only a managed switch can achieve a ring topology connection.

Transportation industry such as rail transit and highway

The whole network communication of the expressway is based on the optical fiber ring network, and is composed of gigabit industrial Ethernet switches supporting the optical fiber ring network. Each site access point uses a layer 2 switch to construct each service application subnet, and a virtual local area network (VLAN) is used to divide each application subnet to realize the actual needs of different services.

Monitoring systems for wind, electricity, telecommunications, etc.

These systems have a harsh application environment and require managed wide-temperature industrial Ethernet switches for network support. Therefore, the Chinese wind power market has increasingly higher requirements for industrial Ethernet switches.

The electromagnetic environment of the monitoring system is harsh, requiring industrial switches to have a strong anti-electromagnetic interference capability and a long average time between failures. For the security of remotely monitored data, the switch needs to have comprehensive network security settings.

In order to guarantee the reliability of communication, it is required to establish a redundant ring network with a small self-healing time. When the communication network fails, it can smoothly switch to the redundant backup line.

Metallurgical and petrochemical, water treatment, coal mine, etc.

Industrial Ethernet is different from general Ethernet, and has higher requirements in terms of network real-time, reliability, and priority of control signals. Therefore, integrated automation systems such as coal mines, metallurgy and petrochemicals, and water treatment are one of the applications of industrial switches. Industrial switches are mainly used for communication of on-site monitoring equipment, such as video monitoring system communication and uploading of on-site I / O acquisition data.

China is known as the world's factory. The factory must have a workshop and a production line. Faced with the construction and renovation projects of many workshop production lines in China, the communication part of the workshop is naturally the market for industrial switches.

In the city's infrastructure construction, industrial switches also have their specific applications and markets. The communication network, sewage power generation network, tap water, natural gas pipeline monitoring network, etc. of each city's sewage treatment plant are the application markets of industrial switches.
