(Organization by electronic enthusiasts) Nowadays in industry, special industrial Ethernet switches are usually used to define different Ethernet frame priority levels, so that the information that users want can be transmitted at the fastest speed. At present, China's industrial Ethernet switch industry as a whole is still in the introduction stage, and downstream customers are mainly concentrated in power, rail transit and other industries. It is expected that the average annual market capacity of industrial Ethernet switches will be around 3 billion yuan during the entire 12th Five-Year Plan period, and the compound growth rate will reach 25% in the next three years.
Industrial Ethernet switch market situation
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. At present, enterprises participating in the domestic industrial Ethernet switch market competition can be divided into two categories: The first category is professional industrial Ethernet switch manufacturers. Professional manufacturers represented by Hessman, Mossa, Dongtu Technology, Roger Kang, and Excellence in Communication are the major enterprises in the domestic industrial Ethernet switch market. Such enterprises have taken the lead in the market and developed rapidly, involving a wide range of industries and having a high market share. Due to its superior resources in power and other industries, Hirschman's domestic market share ranks first in a short period of time and will not change. However, the price of Hersman products is relatively high, and will face the challenges of Mosha, Dongtu Technology, Roger Kang and other companies in the future.
The second category is large system integrators represented by Siemens and Schneider. System integrators such as Siemens and Schneider are both industrial Ethernet switch manufacturers and industrial Ethernet switch users. However, at present, these enterprises have not focused on the promotion of switch products, but they still have a greater impact on the domestic industrial Ethernet switch market.
At present, the domestic industrial Ethernet switch market is mainly dominated by foreign-funded or Taiwan-funded brands. Among the top ten manufacturers, except the company, they are all foreign-funded or Taiwan-funded enterprises. The concentration of the domestic industrial Ethernet switch industry is relatively high. In 2009 and 2010, the total market share of the top ten industrial Ethernet switch manufacturers in the domestic market exceeded 80%. With the rapid growth of the domestic industrial Ethernet switch market, the number of enterprises entering this field will gradually increase in the next few years, and market competition will become increasingly fierce. For some time to come, new companies will still be dominated by European, American and Taiwanese companies. Domestic companies still face greater difficulties in entering this field due to technical and financial constraints. And what are the basic needs of the market for the performance of industrial Ethernet switches?
Market requirements for industrial switch products
Automation is currently the mainstream trend in the development of global industrial manufacturing, and a series of automation equipment industry markets are rapidly expanding. A complete automated production line includes PLC, system control software, industrial robot, etc., and these components need to be connected by industrial Ethernet to form a unified whole. Industrial Ethernet is an efficient local area network. It is an important part of the modern industrial automation production system. Whether it is sensor data transmission or production equipment control, etc., these require Ethernet to form a basic control network. This is also one of the important reasons why industrial Ethernet is more and more widely used in automated production.
In recent years, the development of network technology and the field of industrial control have increasingly higher requirements on network performance. Ethernet is gradually entering the field of industrial control, forming a new type of Ethernet control network technology. Therefore, industrial Ethernet communication requires sufficient high real-time performance, high reliability, anti-interference, anti-network failure, anti-interception, and anti-counterfeiting performance to ensure high-quality control data communication.
Compared with ordinary Ethernet, industrial Ethernet needs to solve many problems such as openness, real-time, synchronization, reliability, anti-interference and security. This is also why industrial automation manufacturers are different from ordinary IT manufacturers. Users bring more value. The traditional Ethernet (Ethernet) is not designed for industrial applications, without considering the adaptability needs of the industrial field environment. The mechanical, climatic, and dust conditions on the industrial site are very harsh. Therefore, higher requirements are placed on the industrial reliability of the equipment. The application in certain high-risk areas is even extremely demanding.
In order to solve the problem of industrial applications, the network can also work steadily under extreme conditions, launched rail hubs, industrial Ethernet switch products, installed on standard DIN rail, and redundant power supply. Industrial switch products have the following characteristics:
1. Redundant power input to prevent single power failure
2. Ring topology structure, providing redundant paths
3. Built-in high-quality and high-reliability parts to ensure a long mean time between failures
4. It can be applied to super-standard temperature conditions, such as -40 ℃ ～ 75 ℃
5. Rugged shell and good temperature resistance
6. Comply with industrial regulations (CE \ FCC \ UL, etc.) and pass strict tests such as impact, drop and shock
