Linear vibrating screens are used to clearly separate all manner of different fractions. Or in technical jargon: Materials are classified accurately. Linear Vibrating Screen,Horizontal Vibrating Screen,Terex Horizontal Screens,Small Vibrating Screen Shenyang Sanland Mining Equipment Manufacture Co., Ltd. , https://www.sanlandcrushers.com In the last two days, in the Jiuzhaigou Scenic Area, the world natural heritage site in the southwestern Sichuan Province of China, two vehicles with the “China Beidou†banner shuttled, which is particularly eye-catching.
The two vehicles, which are somewhat "mysterious" to visitors, are testing the satellite navigation signals of China's self-constructed and independently operating Beidou satellite navigation system at different locations in the scenic area located in the valley. This test is a fundamental work of the China National Science and Technology Support Program – “Intelligent Navigation Search and Rescue Terminal and its Regional Application Demonstration Systemâ€.
The science and technology project with a total investment of about 110 million yuan will make full use of Beidou satellite navigation system and other related technologies to realize personalized functions such as personalized service for visitors, seamless communication coverage, fast rescue, and intelligent management of scenic spots in Jiuzhaigou. .
Wang Wei, senior engineer of the 54th Research Institute of China Electronics Technology Group Corporation and deputy director of the satellite navigation professional department, is a representative of the test work. He told Xinhua that the use of satellite navigation systems for scenic spot management is not uncommon in the world, for example. The Galileo system in Europe is used for tourist hiking and search and rescue services in the Alps.
The 54th Research Institute is the main participant in the development of the Beidou satellite navigation system terminal. Wang Wei told reporters that although the Beidou satellite navigation system has not yet been fully completed, the industry is currently striving to promote the demonstration and application of the navigation system. The demonstration application of the Jiuzhaigou scenic spot is only a microcosm of the numerous demonstration applications of the Beidou system, and according to him The prospects for the next industrial chain development of the Beidou navigation system are also very promising.
"Now the private investment in the Beidou terminal research and development is very positive. Our scientific and technological community is also very optimistic." Wang Wei said.
China announced on the 27th of last month that Beidou satellite navigation system began to provide continuous passive positioning, navigation, timing and other trial operation services to China and surrounding areas. At present, the Beidou satellite navigation system has launched 10 satellites and built the basic system. China plans to form a service capacity covering most of Asia-Pacific around 2012, and will form a global coverage capacity by around 2020.
Yu Yujun, the project director of the China Satellite Navigation System Management Office, also came to Jiuzhaigou to introduce the current status of the Beidou satellite navigation system to Chinese and foreign scholars attending an international forum on spatial information technology and scenic intelligent management.
Qi Yujun said that the Beidou satellite navigation system terminal is currently being demonstrated in different fields, different industries and different regions. It is hoped that “the industry will use the industry demonstration to drive the application of the industry and the regional demonstration to drive the regional applicationâ€.
He revealed that Beidou terminal has carried out user trial evaluation test. Up to now, more than 40 manufacturers have participated in the research and development of 290 sets (sets) of terminals, and its vehicle test journey has spanned 17 provinces and cities, with a cumulative journey of about 800,000 kilometers.
Yan Yujun said that in the context of the US GPS satellite navigation system has been deeply rooted in the hearts of the people, although Beidou is facing the challenge of application promotion and innovation model, the huge market space still supports the development potential of Beidou.
He said that from 2001 to 2009, the average annual growth rate of China's satellite navigation application market was close to 50%. In 2010, the annual output value reached 50.5 billion yuan, and in 2011 it exceeded 70 billion yuan. Previously, Bei Cheng, a spokesperson for the Beidou satellite navigation system and director of the China Satellite Navigation System Management Office, said that once the relevant technologies are mature and applied, the Chinese satellite navigation industry will enter the blowout period. In 2020, the annual output value of China's satellite navigation industry is expected to reach 400 billion yuan.
Yu Yujun said that in the process of competing with other navigation systems, Beidou will give full play to the characteristics of its services and creatively propose competitive application solutions and promotion strategies to win market space.
Wang Wei revealed to reporters that unlike the government's efforts to use demonstration and application, private investment has already been driven by Beidou's “good†drive. According to his observation, many companies in China are busy researching and developing Beidou terminals. He expects that many companies will release Beidou and GPS compatible terminals in the near future.
According to Yu Yujun, the application of Beidou will not be limited to China. He said that his office has joined forces with the China National Civil Aviation Administration and the Ministry of Transport to jointly promote the integration of the Beidou system into international organizations such as ICAO and IMO, laying the foundation for Beidou applications to go global. At the same time, Beidou will also be compatible with other satellite navigation systems and actively promote interoperability with other satellite navigation systems.
Yu Yujun said that China will strive to bring Beidou regional services into the ICAO standard framework in 2015 and provide application services for civil aviation in the Asia-Pacific region.
The Beidou satellite navigation system is a global satellite navigation system built and operated independently by China and compatible with other satellite navigation systems in the world. It can provide high-precision and high-reliability positioning for all kinds of users around the clock, all day and around the world. Navigation, timing service, and short message communication capabilities.
There are currently four global satellite navigation systems in the world: the US GPS, the Russian GLONASS system, the Galileo system under construction in Europe, and the Beidou in China.
Thus, in accordance with the standard screening principle, ore, coal, coke sinter, pellets or rocks, for instance, are screened and clearly separated in very large quantities. Linear vibrating screens, which can be specially adapted to the tasks, are critical here to achieving high and consistent quality.
Shenyang SANLAND already provides linear screens in standard format in a variety of designs. For example as single or multiple-decks.
The applications are wide-ranging. Linear vibrating screens are used in the pit, quarry, coal, ore and steel industries.
