In 2011, Siemens China's performance had risen sharply; but a year later, due to the macroeconomic downturn and the declining demand in some domestic markets, the company’s performance declined slightly this year. Among them, the new orders received amounted to 6.04 billion euros, and the revenue amounted to 6.35 billion euros. In 2011, these two figures were 6.24 billion euros and 6.39 billion euros, respectively.
CEO of Siemens Northeast Asia and president and CEO of Siemens (China) Co., Ltd. Cheng Meiji told reporters that there are challenges in the market. Next, the company is responding to new changes through integration, cost reduction and business adjustment. In the near term, China’s economy is stabilizing, which will bring positive energy to Siemens’ 2013 performance improvement.
Siemens currently has four business segments, namely energy, industrial business and medical, infrastructure and cities. Cheng Meixi did not specify in detail which business area was developing faster this year, but expressed satisfaction with the medical industry. “Siemens will also dig deeper into the rural medical market and promote those that are easy to use, easy to maintain, affordable, reliable, durable and timely. Shangyu's innovative products."
As some of the country’s large-scale rail transit projects have not been implemented properly this year, and shipments of wind power equipment are declining, it has had a negative effect on Siemens’ China operations. However, Siemens has signed a series of wind power cooperation agreements with Shanghai Electric this year. The standpoint of the investment projects of both parties is still large-scale offshore wind power products. This is not the same as the general manufacturing field of megawatt-class wind turbines and has a negative impact on Siemens' business. Not too big.
The coordination and change of Siemens' internal business was not interrupted in 2012. First of all, the company has appointed 25 “regional key account managers†this year, more than double the previous fiscal year, which shows that the overall expansion of the market has been strengthened; secondly, Siemens’ “infrastructure and city†business The area has also recently completed the integration of the sales teams of the “middle and low voltage†and “building technology†segments to respond more quickly to market demand and obtain more orders.
First, what is the classification of industrial routers?
Industrial Router (a communication device that can be divided into 2G routers, 2.5G routers, 3G routers and 4G routers according to network standards.
For users, you can communicate with the Internet by setting a default gateway on your PC or network device. In fact, the default gateway configured for network devices is the packet export for network devices. After the packet is sent to the Ethernet port of the router, the router performs the next job, so the router is an Internet relay.
Second, how do industrial routers work
So how does the router forward the packet? Just like getting somewhere, you need to place a route. This route is a routing table. This routing table contains all the destination network addresses owned by the router, as well as the best path to reach those networks through the router. This is because there is a routing table, so the router can forward packets according to the routing table. That's how routers work.
Understand what is an industrial router and how it works, it is not difficult to understand the advantages and disadvantages of the router. Here we focus on the advantages and disadvantages of 4G industrial routers.
Third, the advantages of 4G industrial routers
For networks interconnected via single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2. Layer 3 uses the same routable protocol and requires the same or compatible protocols at layer 4 and beyond.
Industrial routers can perform complex routing calculations and are suitable for connecting three or more large networks with complex network topologies.
Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and mitigating the impact of broadcast storms.
Multiprotocol industrial wireless routers can be used as network interconnection platforms using different communication protocols because they can connect to the network using different communication protocols.
The entire network router can also be used as a bridge to handle non-routable protocols.
Industrial 4G routers enable you to isolate unnecessary communications so that the interconnected network maintains its own area of independent management and control, thereby improving network security performance. Therefore, industrial-grade 4G routers are commonly used as firewalls to restrict access to the internal and external networks (Internet) of the LAN, as well as the internal areas of the LAN, and act as network masking.
It can provide reliable transport and prioritization services, and industrial LTE routers do not need to maintain a persistent connection between networks that communicate with each other.
Complete Netcom router network segmentation improves network performance and reduces host load.
Third, the advantages of 4G industrial routers
High price
When installing an industrial LTE router, it is difficult to install and maintain due to the large number of initial configurations
If you spend more time processing, the transmission performance of the entire network of the industrial router will decrease.
Unlike Bridges, routers across industrial networks are protocol-related. Each advanced protocol used for network connectivity must be configured separately, and an industrial-grade network-grade router with a separate protocol for each protocol must be provided.
Industrial Netcom routers do not support non-routed protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.
