Industrial switch ranking, please recommend.
Industrial Ethernet switches are widely used in power, transportation and industrial automation industries, followed by security monitoring market. Therefore, to see the ranking of industrial switches, we need to start from these industries.
At present, the industrial switch market can be divided into imported brands and domestic brands. With the gradual development of Made in China 2025 and Industry 4.0, the market of industrial switches is growing, but the share of imported brands in China is shrinking.
At present, the famous imported brands are hessman, Siemens and Mosa. Luo, which was the first in the power industry in that year, has been acquired by Siemens. These three brands have their own characteristics:
Hessman's market share in the field of transportation is second to none: especially the signal system of rail transit. Its product software is perfect, stable and easy to use. Some of its products are made in Germany, some are made in Suzhou, and some products are branded. In fact, it doesn't matter where it is produced or where it is branded. What is important is that hessman's quality management system is extremely perfect, which is the ultimate guarantee for users.
Siemens dominates industrial automation market share: Siemens is a comprehensive industrial automation manufacturer, focusing on providing overall solutions. Its industrial switch is invincible with its PLC. However, compared with hessman, Siemens' software is more inclined to industrial control than strong exchange ability. Compared with hessman, the system of after-sales service is also different. Some products of Siemens are also produced by OEM to improve their competitiveness.
Mosa is the only imported brand that still has a share in the power market, and only China Southern Power Grid. At that time, because of the security problem of the back door of an imported brand industrial switch, the Ministry of Industry and Information Technology put forward large-scale rectification requirements for the State Grid and China Southern Power Grid. This incident directly led to the sharp decline or even basic disappearance of the share of imported brands in the power industry. This industry is dominated by domestic brands.
In terms of product grade, the product grade in hessman should be the highest. Its latest products are all Broadcom-based switching chips, especially its top-end MACH4500. It is not easy to make 88 modular ports at the height of 2U. The top-end products of Siemens and Mosa still stay on Marvell's chips.
In the sales mode, imported brands rely heavily on channels and agents for sales. This method has both advantages and disadvantages. The advantage is wide coverage, and many small projects supporting industrial systems can be done directly through channels and agents. However, under the general trend that the network is extremely developed and the intermediate links are removed, the sales mode of this channel and agent will lead to high prices.
In terms of after-sales service, imported brands are definitely not as good as domestic brands. Domestic brands can already be on call. After-sales service is a good breakthrough for domestic brands to catch up with imported brands.
Well-known brands of industrial switches in China include Meridian of Shanghai Boying Company, Dongtu of Beijing Grand Hyatt Flying Company and Wangsan of Shenzhen Wangsan Communication Company. Because the industrial automation market is fragmented, it emphasizes matching. Compared with the three international brands, the three domestic brands have no advantages in channels and agents, and they are not doing very well in this market. The main markets of domestic industrial switches are electricity, transportation and security.
In the field of electric power, due to the particularity of the three major power production companies of State Grid, China Southern Power Grid and cities, many brands you see in the electric power industry are seemingly mixed. Many local power companies have their own industrial switch brands. The main primary manufacturers in the power industry are Ziwu and Dongtu. Most industrial switches in the power industry are the brands of these two companies, of which Ziwu accounts for about 60%, Dongtu accounts for about 30%, and the remaining 10% are relatively small companies.
In the power industry, the requirements for industrial switches are relatively closed and special, not only for wide temperature and electromagnetic compatibility, but also for various software models, management models and redundant protection in the power industry. Therefore, since Luo gradually disappeared in the power supply industry, these two domestic brands have basically completely occupied this market.
In the transportation industry, especially high-speed rail and urban rail, domestic brands are mainly Dongtu and Meridian. However, in these two industries, the market share of domestic brands is still relatively low compared with international brands, especially in the signal system related to train control. From the perspective of domestic brands alone, the subway industry is the first in the meridian and the second in the east, and the share of the two brands accounts for about 80% of all domestic brands; The high-speed rail industry ranks first in the east and second in the meridian. These two brands together account for about 70% of all domestic brands. This is really gratifying for the self-reliant China brand in China. However, these two domestic brands will continue to work hard and continue to reduce the market share of imported brands, especially signal systems.
In the security industry, it has become a mainstream trend to adopt industrial switches for field access switches, especially for PPP projects. Investors hope to replace a batch of equipment within five years. Therefore, high requirements are put forward for the life and stability of foreign exchange. Wang San is the best in this industry, accounting for about one-third of the market share, Meridian and Dongtu account for one-third of the market share, and the rest are basically excellent, rich and promising. Of course, because this market is very sensitive to price, the most basic requirement is only wide temperature operation, so there are indeed many garbage manufacturers in this market who are shoddy and shoddy.
For these three domestic brands, if they want to fully occupy the domestic industrial switch market within 5- 10 years, they must be twisted into a rope, not only to have healthy market competition, but also to continuously improve product quality and management ability. Chinese people's expectations of these three companies can be summarized as follows: expelling import power upwards and shielding domestic garbage downwards.
As for Cisco, Huawei, H3C and other civil switch manufacturers and industrial computer manufacturers such as Advantec, EVOC and Huabei Technology, they all have their own small number of industrial switches, but they all exist for their civil switch/industrial computer projects, and generally these manufacturers will not promote them separately; As for the so-called top ten industrial switch brands held by a certain media in a certain year, they were all bought with money.
From the perspective of products, there is still a certain gap between domestic brands and imported brands. Industrial switches are mainly used in key industries and places, so the requirements for their security, stability and reliability are much higher than those of telecom, commercial and civil switches. The most important thing to measure industrial switches is the perfection of their certifications. Among them, the most basic and essential definition is that the certification of industrial switches is different from that of commercial switches, and it is the following industrial control equipment safety certification:
1.UL6 10 10- 1，
2.ul 6 10 10-2-20 1，
3.cUL6 10 10，CAN/CSA-c 22.2 no . 6 10 10- 1，
4.CAN/CSA-C22.2No.6 10 10-2-20 1,
5. C610/0cInclusion Europe, Scandinavia, USA, Australia, Canada, Japan and China,
6.EN55032ClassA，
7.EN55024，
8.EN6 1000-3-2，
9.EN6 1000-3-3，
10. Cylinder 6 10 10- 1,
1 1.LVDDirective20 14/35/EU，
12.EMC directive 20 14/30/eu 1，
13.EN6 1000-6-4，
14.EN6 1000-6-2，
15.FCCPart 15ClassA
In addition to the above basic industrial equipment safety certification, there are also system certification requirements for manufacturers. For example, if a brand wants to expand into the railway and subway industries, the company must have IRIS international railway quality system certification, and the power security industry needs ISO9000 series quality management system certification, ISO 1400 1 environmental management system certification, and OHASA 1800 1 occupational health and safety. Of course, there is also the certification of the company's software capabilities, such as all kinds of IPv6 software copyrights, dual-master software copyrights and so on.
Different applications in various industries also have relevant industry certifications of industrial switches, such as EN50 12 1 and NEMA EN50 155 in transportation industry. Electric power industry automation industry en 61131; Security monitoring industry certification of the Ministry of Public Security; ATEX and various fire and explosion-proof certifications in dangerous areas.
Switches without the above certification cannot be called industrial switches, but can only be called reinforced switches or wide temperature switches at most.
There is a flood of information on the Internet, and there are countless votes for various ranking awards. The potential users of industrial switches should not trust the articles found on the Internet too much, but should have some basic abilities to judge the quality of industrial switches themselves. Next, list some simple and easy-to-understand methods and ways to judge the level of industrial switches:
1. shell: the shell of high-quality industrial switches is generally aluminum alloy or flame-retardant plastic, but generally iron shell is not used. The problem with iron shells is that they will rust over time. Although the iron shell can be prevented from rusting by painting and plastic spraying, painting and plastic spraying can not cover the cutting edge of the iron sheet or the bonding is not firm enough. Rust begins at the edge of the iron shell. Once rust enters the equipment, industrial switches with high requirements for life and stability are fatal; Therefore, from this perspective, the lighter the industrial switch, the better, rather than the heavier it is in common sense.
2. Screws: High-quality industrial switches generally use stainless steel or stainless steel iron plum blossom screws instead of ordinary cross screws. The reason for using Torx screws is obvious, so I won't describe it here.
3. Circuit board: High-quality industrial switches generally use gold-plated circuit boards instead of tin-plated circuit boards. Although the cost has increased a lot, the quality, stability and consistency of printed circuit boards are much higher.
4. Electrolytic capacitor: At present, electrolytic capacitor is the most fragile component among the common components of electronic products. High-quality industrial switches can avoid using tantalum capacitors and polymer capacitors wherever electrolytic capacitors are used; Japanese, American and European electrolytic capacitors are generally used for the inevitable high-voltage part of electrolytic capacitors, and Taiwan Province or domestic electrolytic capacitors will not be used.
5. Fan: The fan is limited by its own transmission and is the main component that drags the life and stability of industrial switches. High-quality industrial switches generally avoid using fans and adopt natural heat dissipation.
6. Main switching chip: Broadcom switches are generally high-end, followed by American brands such as Microsemi and Marvell. Then there are Realtek, Icplus and so on in Taiwan Province. There are basically no mature domestic switch chips suitable for industrial switches.
7. Software: Look at the command line manual of the switch and the WEB management interface of the switch. Don't look at the function, just pay attention to whether the instructions are neat, whether there are typos on the webpage, and whether English is fluent.
The quality of industrial switches that can achieve the above seven points will not be very bad.
