The Main Application Industry Of Industrial Ethernet Switch
In 2009, the total market size of China's network exchange equipment is 870 million yuan, of which the market size of switch and serial port server is 740 million yuan. Compared with the 610 million yuan growth rate of 610 million yuan in 2008, China's network switching equipment gradually matured and stabilized.
In 2009, as in 2008, China's network exchange equipment market was mainly used in the electric power and rail transit industries. The sum of the applications in these two industries could account for more than 50 percent of the scale of China's network exchange equipment market. And these two industries are the basic industries related to the national economy and people's livelihood and the key industries supported by the state in 2009.
In 2009, the scale of national power construction investment maintained a relatively rapid growth, the structure of power investment continued to be optimized, the proportion of thermal power investment dropped substantially, the proportion of nuclear power investment and wind power investment increased by a large margin, and the growth of power grid investment continued to accelerate. The scale of investment in power investment has reached 50.9%. Data show that the annual investment in electric power construction reached 755.84 billion yuan, an increase of 19.9 yuan. The investment in nuclear power and wind power infrastructure increased by 74.9 percent and 43.9 percent respectively, while the amount of capital construction investment in thermal power decreased by 11.1 percent from the same period last year. Investment in the power grid completed 384.71 billion yuan, an increase of 32. 9% over the same period last year.
The role of substations is to reduce long distance high voltage to civilian voltage (e. G. 110, 000 V to 380 V / 220 V / V). A power grid needs not only substations at all levels, but also a complete communication system. This communication system mainly completes the transmission of all kinds of data. Industrial fiber Ethernet switch is one of the most commonly used communication products in substation. Because of this, network switching equipment in the power industry applications occupy a large scale.
Rail transit industry
By the end of 2009 , more than 40 cities have built or are planning to build urban rail transit projects such as subway , light rail and other urban rail transit projects , the total mileage of the approved urban rail transit projects is nearly 2000 km , and the total investment will exceed 60 billion yuan . Thanks to the country ' s investment in the industry , the network switching equipment has also been used more and more in this industry .
The application of network switching equipment in rail transit industry includes comprehensive monitoring system , communication system , video monitoring system , power supply system , disaster prevention alarm monitoring system , management information system , etc .
