Recently, the National Standardization Management Committee issued the No. 27 announcement in 2014. The national standard developed by the Hefei Institute of Material Science of the Chinese Academy of Sciences, the national standard “Information Technology Sensor Network Part 701: Sensor Interface Signal Interface†and other three national standards have passed the national quality. The General Administration of Supervision, Quarantine and Quarantine and the National Standardization Administration Committee approved the official release.
As one of the basic standards of the national Internet of Things, the signal interface standard specifies the signal type, electrical parameters and expression format of the signal interface between the sensor and the sensor node. It is designed to facilitate system integration between the sensor and the sensor node and realize software reuse.
In the construction of smart cities, the Internet of Things plays a very important role, and the sensor is the "nerve ending" of the Internet of Things. In the face of the development of a large-scale smart city, the “difficult situation†of the development of key components of China's sensors is even more prominent.
Internet of Things becomes the focus of national innovation strategy
“Smart City is a new generation of information technology that uses the next generation of information technology such as Internet of Things, cloud computing, big data, and spatial geographic information integration to promote urban planning, construction, management, and intelligent service.†Earlier this year, the State Council It is agreed that the eight ministries and commissions such as the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Science and Technology have issued the "Guiding Opinions on Promoting the Healthy Development of Smart Cities." The "Guidance Opinion" not only puts forward the definition of smart city, but also puts forward specific requirements such as "accelerating the application of Internet of Things in key areas" in order to promote the construction of smart cities.
The "Guidance Opinion" puts forward in the "active use of new technologies and new formats", "accelerating the application of Internet of Things in key areas. Supporting the application of the Internet of Things in high-energy-consuming industries, promoting the automation of manufacturing, operation management and energy utilization. Encouraging the Internet of Things Application in the fields of agricultural product production and circulation, etc. Accelerate the promotion and application of Internet of Things in urban management, transportation, energy conservation and emission reduction, food and drug safety, social security, medical and health care, people's livelihood services, public safety, product quality, etc. The level of gradualization has gradually formed a comprehensive sensory and widely interconnected urban intelligent management and service system."
Mao Weiming, deputy director of the Ministry of Industry and Information Technology, pointed out at the 2nd International (Hangzhou) Internet of Things and Sensing Technology and Application Summit that the Internet of Things is a highly integrated and integrated application of a new generation of information technology, with a huge market and industrial space. . Vigorously promoting the advancement of sensing technology and accelerating the development of the Internet of Things are important measures to promote the deep integration of informationization and industrialization, accelerate structural adjustment and transform the development mode, and also be strategic choices to enhance national competitiveness and promote national economic transformation at a high starting point.
Hong Jingyi, director of the First Institute of Electronics and Electronics of the Ministry of Industry and Information Technology, believes that on the basis of the current stabilization of the international economic recovery, the Internet of Things has become an important means for countries around the world to get rid of the financial crisis, achieve economic recovery and occupy the commanding heights of global competition. The developed countries and regions such as the United States, Europe, Japan and South Korea have regarded the Internet of Things as an important area for future development and seek to occupy a favorable position in the fierce international competition in the future.
An important part of the integration of the physical world and the information world
"The Internet of Things is characterized by the ability to make things "speak and publish information" through perception and recognition technology. It is an important part of the integration of the physical world and the information world. It is also the most unique part of the Internet of Things that distinguishes it from other networks. Currently, the United States The Internet of Things has been raised as one of the priorities of the national innovation strategy. The EU has developed a 14-point action plan to promote the development of the Internet of Things. Japan plans to use the Internet of Things as one of the four key strategic areas. South Korea regards the Internet of Things as the three infrastructures. One of the key points.†Academician of the Chinese Academy of Engineering and Professor of the Tsinghua University said.
It is reported that in 2013, the scale of China's Internet of Things industry exceeded 500 billion yuan, with a compound annual growth rate of over 30%, and it has a good industrial base and development prospects. The technical strength in the fields of sensors, radio frequency identification (RFID), communication protocols, network management, intelligent computing, and collaborative processing has been continuously improved, and some scientific research achievements have reached the world's leading level. All regions and relevant departments actively promoted the application of the Internet of Things in related fields, carried out a series of application pilots and demonstration projects, and achieved positive results.
However, Mao Weiming believes that as an emerging industry, the development of the Internet of Things industry is still in its infancy, the innovation capability needs to be improved, the lack of leading enterprises, and the lack of scale application, which have become the key factors restricting the development of the industry.
Therefore, he stressed that “the development of the Internet of Things industry is a systematic project that requires extensive participation and strong support from all sectors including governments, enterprises and research institutions.â€
Sensor development lags behind the main obstacles of the Internet of Things
The "Guiding Opinions" puts forward in the "Scientific Formulation of Smart City Construction Top Level Design" to promote the construction of a livable living environment. Establish an environmental information intelligent analysis system, an early warning emergency system and an environmental quality management public service system for key areas and key enterprises. Implement intelligent remote monitoring with pollution sources... Establish a modern industrial development system. Use modern information technology to accelerate the establishment of a new agricultural production and management system that closely links the urban logistics distribution system with urban consumer demand and agricultural product supply..."
The Institute of Electronic Science and Technology Information of the Ministry of Industry and Information Technology released the White Paper on the Development of China's Sensor Industry (2014) at the forum. According to the "White Paper", the fastest growing market in the global sensor market is the automotive market; in addition to intelligent applications in the transportation field, China's sensors are also in the process of intelligent process control and safe production; in the field of intelligent agriculture, fine management, quality and safety of agricultural products. Retrospective; intelligent and environmentally friendly pollution source monitoring, water source protection; intelligent medical special population care, telemedicine, and smart wearable devices are widely used.
Mao Weiming said that as the core of the Internet of Things technology, sensing technology is the key to acquiring and processing information, and its development level is an important indicator to measure the degree of informationization of a country.
"The core technologies of the Internet of Things mainly include information sensing acquisition technology, network construction technology, and service management technology." You Zheng said that as the most basic application layer of the Internet of Things - an important component of the sensing layer, sensors in the Internet of Things The importance of the status is an important prerequisite for the establishment of the Internet of Things. "But at present, the development of key components of China's sensors is lagging behind, and core sensor components are subject to people, which has become a major obstacle to the development of China's Internet of Things."
According to the White Paper, the global sensor market in 2013 was approximately $105.5 billion. It is predicted that the global sensor market will maintain a growth rate of more than 20% in the next few years, and the market size will exceed 150 billion US dollars in 2015. China's domestic sensor market continues to grow rapidly, with an average annual growth rate of more than 20%, and more than 64 billion yuan in 2013.
However, from the overall situation of the world, a few developed countries such as the United States, Japan, and Germany occupy more than 70% of the sensor market; the advantages of technology and brand in developed countries in the sensor field will remain in the next few years. At present, China's sensor industry has formed a complete industrial system from technology research and development, design, production to application under the support of national policies. There are 10 categories and 42 categories of more than 6,000 kinds of sensor products. The middle and low-end products basically meet the market demand and product varieties. The satisfaction rate is 60%-70%. However, from the perspective of industry product structure, the proportion of old products is over 60%, and new products are obviously insufficient. Among them, there are fewer high-tech products. At the same time, digital, intelligent and miniaturized products are seriously lacking.
The "White Paper" also pointed out that the main problems facing the development of the domestic sensor industry are: first, the scale of enterprises is small, high-end products are heavily dependent on imports, of which sensor chips account for up to 90%; second, the overall level of technology is low, many companies are It is difficult to independently innovate by citing foreign originals. Third, the product structure is unreasonable, and the varieties, specifications and series are incomplete. Fourth, the level of industrialization is low and the industry is insufficient.
Enhance sensor, IoT core technology
How to promote the development of the Internet of Things and the sensor industry?
Mao Weiming emphasized that planning guidance and policy guidance should be strengthened, a special action plan for the development of the Internet of Things should be organized and implemented, and the “Twelfth Five-Year Development Plan for the Internet of Things†should be continued to promote the sustainable and healthy development of China's Internet of Things in an orderly manner; The construction of the demonstration zone will form a pattern in which each link in each region will play an advantage, division of labor and cooperation, and synergy; strengthen core technology research and standard formulation, focus on the key links of the IoT industry chain, concentrate resources to break through core technologies and major key common technologies, and accelerate the project. The establishment of a networked standard system, actively participate in the formulation of international standards; actively guide industry demonstration applications, select a number of key areas, coordinate the deployment of IoT applications and perceived infrastructure, explore innovative business models and institutional mechanisms; further coordinate, implement and improve policy measures Strengthen the coordination, interaction and coordination of industrial policies, science and technology policies, fiscal and taxation policies, financial policies, land policies, and talent policies.
You Zheng said that it is also necessary to combine breakthroughs with overall improvement; launch support for high-end development of large and medium-sized enterprises, and focus on solving support policies for private SMEs; and formulate policies for fiscal, procurement, and distribution to independent R&D.
