The so-called "Internet of Things" (internet of
things, iot), also known as the sensing network, refers to a variety of information sensing equipment, such as radio frequency identification (rfid) devices, Infrared sensors, global positioning systems, laser scanners and other devices connected to the Internet and form a network that can realize intelligent identification and manageable.
Foresight Industry Research Institute data show that in 2016 China's Internet of Things industry scale more than 900 billion yuan, year-on-year growth rate of more than 20% for many years. As an emerging application in the communications industry, IoT will further expand its market size under the general trend of Internet of Everything. With the improvement of industry standards, continuous technological progress, and national policy support, China's IoT industry will continue its good momentum of development, providing new impetus for sustained and stable economic growth. The wave of expansion of mobile Internet to Internet of Everything will enable China to create a larger market space and industrial opportunities compared to the Internet.
The Internet of Things (IoT) makes use of the technical means of sensing, capturing and measuring such as radio frequency identification (rfid), gps, cameras, sensors, sensor networks, etc., to collect and acquire information about objects anytime and anywhere, and realize intelligent decision-making and control. Therefore, the Internet of Things in the industrial field in the application process, the Internet of Things-related technologies and products is the core of intelligent industry.
Industry is an important field of IOT application. Various types of terminals with the ability to sense the environment, ubiquitous technology-based computing model, mobile communications, etc. continue to be integrated into all aspects of industrial production, which can significantly improve manufacturing efficiency, improve product quality, reduce product costs and resource consumption, and accelerate the transformation of traditional industry to intelligent.
According to the "Internet of Things Industry Applications Market Demand and Investment Forecast Analysis Report" released by the Prospect Industry Research Institute, in 2014, the domestic Internet of Things in the industrial sector demand scale of 126 billion yuan; in 2016, the domestic Internet of Things in the industrial sector demand scale of 184.4 billion yuan. 2017, the domestic Internet of Things in the industrial sector demand scale of about 235.4 billion yuan. .
Analysis of the application problems of the Internet of Things in the industrial field
1, it security problems
Unlike the previous industrial revolutions brought about by new hard devices and technologies, Industry 4.0 is the fourth industrial revolution brought about by the Internet. Therefore, 66% of respondents believe that it security is a major challenge, when the enterprise's it system connected to the network, there may be some unknown threats at any time in the warehouse management system, machinery and equipment or supply chain.
2, manufacturing system management issues
Industry 4.0 in addition to bringing production efficiency, but also change the traditional manufacturing thinking. When the real implementation of intelligent production, will bring great changes to the manufacturing management system, and is bound to become more complex, including the overall production logistics, human-machine co-operation and other changes, but also to make staff training more important.
3, communication infrastructure issues
Communication network is an important key to the realization of Industry 4.0, but to establish a network so that all organizations can work together, there must be a consistent interface, communication standards and specifications. Many of these standards have yet to be established, such as industrial communications, engineering, it security, digital factories, and device integration have yet to be incorporated into an overall reference architecture.
IoT in the industrial field application prospects and development trend prediction
In recent years, China's government through the integration of industrialization and informatization strategy is vigorously promoting the Internet of Things technology to the depth of penetration of traditional industries. The pilot work of Internet-industry integration and innovation, which was highlighted in the Special Action Plan for the Deep Integration of Industrialization and Informatization (2013-2018) issued by the Ministry of Industry and Information Technology (MIIT) in September 2013, has entered the stage of full implementation.
The new networked and intelligent production mode characterized by Internet of Things convergence and innovation is shaping the core competitiveness of future manufacturing industry, promoting the formation of new ways of industrial organization, new enterprise-user relations, new service modes and new business models, and promoting the transformation of traditional industrial fields such as automobiles, aircrafts, engineering equipments and home appliances into networked, intelligent, flexible and service-oriented fields, which will nurture and promote the development of the global new The development of the industrial revolution.
U.S. manufacturing giant General Electric has made full use of IoT technology, and has launched more than twenty industrial Internet/IoT application products, covering various fields such as monitoring and management of oil and gas platforms, analysis of the efficiency of railroad locomotives, enhancement of the power output of wind power generators, optimization of the distribution system of electric power utilities, and cloud imaging in healthcare. at
