The role of industrial switches
Industrial Ethernet switch is mainly used for real-time Ethernet data transmission in complex industrial environment. In the design of Ethernet, because of its carrier sense multiple access collision detection (CSMA/CD), its reliability is greatly reduced in the complex industrial environment. Industrial Ethernet switches with switching mode conversion and improve the speed of storage, Ethernet communication, and built-in intelligent alarm condition monitoring network design, the Ethernet reliable operation in harsh industrial environment in danger.
Industrial switches and ordinary switches
The difference between industrial Ethernet switch and general switch is mainly reflected in the function and performance.
The main difference is that the function of industrial Ethernet switch is more close to the industrial network communication, such as the interconnection with the various fieldbus, the redundancy of the equipment and the real-time of the equipment;
The difference is mainly reflected in the performance of the external environment to adapt to different parameters. In addition to the industrial environment, such as: coal mines, ships and other particularly harsh environment, as well as in the EMI (electromagnetic compatibility), temperature, humidity and dust and other special requirements of the environment. The influence of temperature on industrial network equipment is the most extensive.
Components: Industrial Ethernet switch components of the selection of higher requirements, to better meet the needs of industrial production site.
Mechanical environment: Industrial Ethernet switches can better adapt to harsh mechanical environments, including shock resistance, impact resistance, corrosion resistance, dust, water, etc..
Climate: Industrial Ethernet switches are better suited to poor climate conditions, including temperature, humidity, etc..
Electromagnetic environment: Industrial Ethernet switch has a strong ability to resist electromagnetic interference.
Working voltage: the working voltage range of the industrial Ethernet switch is wider, and the common switch has higher requirements on the voltage.
Power supply design: ordinary switches are basically a single power supply, and the power of industrial switches are generally dual power backup.
Installation: Industrial Ethernet switch can be used DIN rail, rack and other installation methods, general switches are generally rack, desktop mode.
Cooling mode: Industrial Ethernet switches are generally non fan shell heat dissipation, while the general switch is fan cooling
Industrial switches and industrial switches
Generally speaking, the switch is generally referred to as the Ethernet switch (excluding telecommunications program control switch, otherwise the interpretation is too complicated).
Ethernet switches are generally divided into: Commercial (Ethernet) switches, industrial (Ethernet) switches, home (Ethernet) switches.
Business exchange is generally used in enterprise office network and other occasions, the general form of rack, installed in the business room, usually require high reliability, can be 24 hours of uninterrupted long-term operation, and more features such as larger interface bandwidth.
Industrial switch is generally used in industrial production situation, usually the appearance and installation forms, according to different applications, requirements of waterproof and dustproof, anti vibration and anti electromagnetic interference, of course, the reliability is high, the same to 24 hours of uninterrupted long-term operation. Some automatic control applications, such as low latency forwarding, some require redundant power supply, DC24V power supply, etc..
Home switches are running out, without much introduction.
Industrial switch is not a standard name, it is commonly known as it. Switches used in the industrial sector are often industrial switches.
Standard for industrial control, program-controlled switches and switches which are 3 things
Industrial control computer is an industrial PC, or PC variant equipment, mainly used to run a special program corresponding to the device.
SPC, this is very simple, is the company to install a switchboard, switchboard and extension if you need this.
The switch is of course the PC used, Ethernet is a standard network protocol, all network we are now used in Ethernet structure, all switch and Ethernet switch is something that is generally not to call it. As for the industrial switch, it should be different from the home network management switch. In fact, this type of product is not so clear definition, and now the network management of the switch is also 2~300, home is no problem.
The other is the working hours, the general industry are supporting 7*24, but now home appliances are often never power, do not distinguish so clear.
