Functions and Applications of Industrial Switches

Industrial Switch, also known as industrial Ethernet switch, is a kind of network machine equipment that can encapsulate and share data files on the second layer of OSI (data information link layer, defined by referring to "local area network") and can be identified according to MAC (detailed address of material key management of network interface). Due to its strong anti-seismic and anti fog standard, it can be widely used in high temperature and electromagnetic interference.

Industrial switch is mainly used for real-time Ethernet data transmission in complex industrial environment. In the design of Ethernet, because it adopts carrier sense multiplexing conflict detection (CSMA / CD mechanism), its reliability is greatly reduced in complex industrial environment where the Ethernet can not be used. The industrial switch adopts the storage conversion switching mode, improves the communication speed of Ethernet, and has built-in intelligent alarm design to monitor the operation of the network, so as to ensure the reliable and stable operation of Ethernet in the harsh and dangerous industrial environment.

Industrial switches are generally used in industrial production occasions. They usually have a variety of appearance and installation forms. According to different applications, they are required to be waterproof, dustproof, earthquake resistant and anti electromagnetic interference. Of course, they also have high reliability requirements. They also need 24-hour uninterrupted long-term operation. Some automatic control applications require low forwarding delay, and some require redundant power supply, DC24V power supply, etc.

With the continuous development of China's equipment manufacturing industry, the intensification of competition and the demand of the international market, industrial switch manufacturers are accelerating the upgrading and upgrading of equipment. How to improve and upgrade the equipment in a very short time and at a very low cost has become an important problem faced by industrial switch manufacturers. The industrial switch adopts the storage conversion switching mode, improves the communication speed of Ethernet, and has built-in intelligent alarm design to monitor the operation of the network, so as to ensure the reliable and stable operation of Ethernet in the harsh and dangerous industrial environment. Advanced technology, scientific architecture, good openness and expansibility, but without making too many adjustments to the equipment, it can expand its performance, increase its functions and save time and effort for users.

Industrial switches are different from ordinary switches because of their relevance to market positioning. They are more related to some industrial characteristics, such as reliability, stability, heat resistance, vibration resistance, corrosion resistance and so on. The industrial Ethernet switch is operated in some manufacturing industries with strict environmental standards because of its relatively high protection level (general IP40), strong electromagnetic compatibility (EMS level IV) and good operating characteristics, which fully ensures the industrial communication. Industrial switches shall be used in smart energy, urban rail, integrated pipe gallery, intelligent transportation, smart city, mining and metallurgy, crude oil, petrochemicals, new energy technology, smart, ships, military, building security and other industries.
