In 2011, experts recommended that the pace of IoT slowed down

In the past year, the Internet of Things has moved forward. Capital, markets, government, and scientific research have all made great efforts to "weave the net." It can be said that "Heavenly Hee-hee is all for profit; the world is unclear. "The Internet of Things has begun to be heavily written in local government development plans, and in the electric power, transportation, logistics, and other fields, with the already existing prototype of the Internet of Things, it is the Internet of Things in the Twelfth Five-Year Plan." Including key areas.

The China Internet of Things Research and Development Center predicts that the market size of China's Internet of Things industry in 2010 will be 200 billion yuan. By 2015, the overall market size of China's Internet of Things will reach 750 billion yuan, and the compound annual growth rate will exceed 30.0%. The market has a huge investment prospect.

Adjusting the pace The top-level layout is different from the vertical division of the general field. The Internet of Things is a horizontally-developed field. It has the characteristics of strong discipline comprehensiveness, long industry chain, and wide penetration range. The demand for China's Internet of Things is mainly found in smart grids, transportation energy logistics, homes, environment and safety inspections, medical and health care, precision agriculture and animal husbandry, industrial and automation control, defense military, finance, and service industries. Although Internet of Things applications can be ubiquitous, it is still dominated by local closed-loop applications and government-led project applications. Cross-industry, cross-department, and application-chain applications are relatively rare.

At present, the development of the Internet of Things lacks the top-level design and overall planning at the national level. There are obvious differences in the definition, connotation, and industrial scope of the Internet of Things among all regions and departments, and the situation of blindly following the trend and proceeding side by side is more prominent. Institutional obstacles such as industry monopolies, fragmentation, and self-contained systems have constrained the combination and benign interaction of IoT technologies, industries, and applications; fragmentation caused by administrative decentralization has weakened the ability of strategic emerging industries to tackle collaborative problems.

Some cities lack a clear judgment on the law and nature of the development of the Internet of Things, entrusting multinational corporations with system solutions such as urban informatization, and occupying the space for independent innovation and development of China's Internet of Things industry and the market share of local companies, and also bringing Information security issues. The development of the Internet of Things is not only a technical issue, but also involves political and legal issues and national security issues. Only with the improvement of laws, regulations, and policies, the Internet of Things can deepen its development.

When you flock, it is easy to lose the long-term planning and strategic direction adjustments. Experts suggest that a high-level government-industry-research alliance should be set up to guide the organization; under the principle of maximizing national interests, the overall control over the development of the Internet of Things should be achieved, and regional and industry characteristics should be used to guide differential development.

Until now, there are still many supporters of the "bubble theory" of the Internet of Things. It is not important to discuss whether it is a bubble, because the concept of the Internet of Things is still in the process of development. Its development period will take 10 to 20 years. Therefore, during the warm-up period of 3 to 5 years of preparation, it is necessary to adjust the pace and deploy it in a farsighted manner.

Hardware to say "hard words"

In terms of technology, the basics and core technologies of the Internet of Things are still very lacking. The convenience of the introduction of technology, to a certain extent, caused the lack of accumulation of core basic technologies in our country. Our sensor design manufacturing industry is almost blank, and it is very likely to become the dumping target for foreign investors who control almost the entire sensor market. Taking an embedded system as an example, its hardware relies on foreign technology. Chips, platform software, and development tools have a big gap with foreign countries. 95% of embedded CPUs rely on imports. In the platform software such as embedded operating system, database and development tools, foreign brands occupy absolute advantages.

The three-tier architecture of the Internet of Things is divided into perception, transmission, and application. The first thing that erupts is the demand of the sensing layer. This layer of hardware requirements is something that domestic manufacturers can't satisfy. It will inevitably bring opportunities for foreign manufacturers and let our country become a substitute. Although the RFID industry chain has been initially formed, there is still a gap between technology and enterprise strength and developed countries. UHF, active RFID, etc. do not form an overall industrial capability, and the independent intellectual property rights of tag chips are poor.

The "Innovation 2050: Science and Technology and China's Future, China's Roadmap to Information Technology Development in 2050" pointed out: "The sensor network is a typical multidisciplinary research involving computers, semiconductors, networks, communications, optics, In many fields such as micro-mechanics, chemistry, biology, aerospace, medicine, agriculture, etc., due to cross-convergence and interaction of disciplines, many technological trends have become possible. For example, biotechnology will greatly rely on laboratory equipment for analysis in chip labs. As well as advances in bioinformatics; MEMS, smart materials, and new materials will make it possible to set universal low-cost, small-scale sensors; engineers will increasingly turn to biologists to understand how organisms solve problems involving the natural environment; these Bio's efforts to combine the best solutions from nature with man-made components can lead to the development of better systems than existing living organisms. The development of basic support technologies can further advance the development of sensor networks/Internet of Things. .

At present, there are a large number of research institutions. Most of them are either focused on basic theory and are far away from application requirements, lacking large-scale engineering practice, focusing on engineering, homogenizing with small and medium-sized enterprises, and being repetitive, making it difficult to promote them quickly and comprehensively, and lacking profitability. business model. What is particularly lacking is the lack of leading enterprises with integrated system solution integration capabilities, with SMEs being mostly sloppy.

At present, Wuxi's China Internet of Things Research and Development Center has focused on more than a dozen research institutes in the Chinese Academy of Sciences engaged in research work on sensors and sensor networks, taking the strengths of various companies and concentrating on conquering technological difficulties and stockpiling core technologies.

In addition, the factors restricting the development of the Internet of Things industry lies in the lack of a unified standard system and a mature business model. Standards are still fragmented, missing, and inconsistent. The combination of standard formulation and market application is not enough, and integration with international standards is insufficient. Only by finding a suitable business model and guiding civil needs can we achieve a benign transition from government investment to social investment.

The problems that need to be solved in the development of China's Internet of Things industry. 1. The concept of the Internet of Things is not uniform and needs to be defined and standardized;

2. The development strategy of the Internet of Things industry is not yet clear, and it is necessary to strengthen top-level design and strategic planning.

3. The core technology needs urgent breakthrough, and it needs to pay great attention to intellectual property and industry standardization;

4. The industrial chain urgently needs to be improved and integrated, and it is necessary to cultivate leading enterprises.

5. The business model is not yet clear and remains to be actively explored;

6. It is urgent to speed up the formulation of national laws and regulations and related supporting policies;

7. Network information security issues should be given enough attention.
