1. Construction background of the Internet of Things engineering laboratory
The Internet of Things, as the name suggests, is the Internet of things connected. This contains two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; second, its user end extends and expands to any item and item to carry out information exchange and communication.Therefore, the Internet of Things refers to the use of sensors, radio frequency identification (RFID), intelligent embedded and other technologies to enable information sensing equipment to perceive any required information in real time, and to connect through possible networks (such as based onWiFiwireless local area network, 2G/3G, etc.) access method, connect any object with the Internet, exchange and communicate information, realize the ubiquitous link between objects and objects, objects and people, and realize intelligent identification, positioning, Track, control and manage.
From “smart earth” to “perceived China”; from new economic growth points to a series of measures supported and encouraged by the government; from the national medium and long-term science and technology development plan to the research of various universities and research institutes, the Internet of Things can be seen important position in the field of science and technology today. In August 2009, Premier Wen Jiabao inspected Wuxi Internet of Things Industry Research Institute and made important instructions: Internet of Things technology is the commanding height of future technology and one of the future development directions of my country’s emerging strategic industries! The overall scale of China’s Internet of Things industry , is expected to exceed 1 trillion in 2015 and 5 trillion in 2020. There is no doubt that the state strongly supports the industrial development of the Internet of Things, and in the next four years, more than 2,000 colleges and universities will build Internet of Things laboratories to cultivate practical talents for the country. The Internet of Things is not a new technology, but a high degree of integration of various technologies such as existing sensing technology, computer network technology, communication technology and automatic control technology. Therefore, how to use the existing equipment to build an experimental environment that meets the needs of the industry will be the key to the construction of the Internet of Things laboratory.
Second, the Internet of Things engineering laboratory construction plan
