Network technology is developing rapidly, and Ethernet occupies a dominant position in the industrial market. The switch provides good flexibility and easy handling for the upgrade of Fast Ethernet. The Ethernet switch will automatically detect the speed of the connected device, allowing 10Mbps and 100Mbps devices to be used on the same switch without replacing the original Network facilities.
Industrial Ethernet switches are generally designed to meet industrial design requirements: industrial wide temperature design, level 4 electromagnetic compatibility design, redundant AC and DC power input, and PCB board generally do "three protection" treatment. The environment of the industrial site is worse than the ordinary environment, at least in terms of vibration, humidity, and temperature. The ordinary switch is not designed to withstand the various situations that occur in the industrial environment. Working in such a harsh environment for time is often prone to failures and increases maintenance costs. It is generally not recommended to use commercial switches in industrial environments. The reliability of environmental switches and industrial-grade switches includes power failure, port interruption, alarm output by relays, redundant dual DC power input, active circuit protection, and automatic disconnection protection for overvoltage and undervoltage.
Currently. In the domestic industrial Ethernet switch market, power and rail transit are the key application areas of industrial switches, accounting for 70% of the market. There are about 50 manufacturers active in the Chinese industrial Ethernet switch market. There are about 15 foreign-funded manufacturers in China's industrial Ethernet switch market, 3-4 Taiwan-funded manufacturers, and about 30 local manufacturers. Local brands are predominant among local manufacturers. In the sales of industrial Ethernet switches, nearly 70% of industrial Ethernet switches enter the market through distribution. Generally, foreign-funded enterprises use distribution to sell products, and domestic-funded enterprises use direct sales.
The constraints of domestic industrial Ethernet are largely due to the lack of a unified general standard, uneven products, large price differences, and difficult choices for users. At the same time, industrial Ethernet technology and field bus technology coexist for a long time. Fieldbus technology will also exist for a long time, which limits the development of industrial Ethernet switches to a wider range of applications.
China's future industrial Ethernet switches will be accompanied by the continuous advancement of industrial automation and the continuous promotion of industrial Ethernet technology applications, ushering in greater development. From a technical point of view, real-time communication, stability, security, etc. are the focus of industrial Ethernet switch products. With the development of network technologies such as wireless networks and Bluetooth, industrial Ethernet switches will continue to move forward. From a product perspective, multi-functionalization is the development direction of industrial Ethernet switches. The managed industrial Ethernet switch is more powerful than the unmanaged type.
