align="left"> American authority consultancy FORRESTER predicts that by 2020, the world's physical interconnection business, compared with the business of human communication, will reach 30 to 1. Therefore, under the "Internet of things" is called a trillion-dollar communications business.

According to the valuation of AT&T, by 2020, the number of connections M2M will reach 50 billion. In fact, with the increasingly mature, M2M solutions as a decline in the cost of communication, sensing devices, Internet of things will gradually penetrate into various industries.

Automobile, machinery, large equipment such as machine of the global Internet, using the new analysis technology and business intelligence solutions, from the huge amounts of data to extract more valuable information, also can provide more value-added services to our customers.

"Internet of things is the most core, is the most basic sensor." China's iot leaves of sweet spring, director of the center for research and development, said without sensor, there is no way to let the machine automatically perceive information. It is because of the sensor to join the network, the concept of Internet of things to be mentioned.

Sensor as modern science and technology at the forefront of technology, is considered to be one of the three pillars of modern information technology, but also one of the most recognized at home and abroad with the future high technology industry development. In sensor in the spring, however, China still seems to be the public see is a feast for the semiconductor giant abroad. The personage inside course of study thinks, although China's sensor market development soon, but the local sensor technology compared with world level there is still a large gap. This gap, on the one hand, show the sensor in terms of sensory information, on the other hand, is characterized by sensor itself in the field of intelligent and networked technology lag behind. Because there is no application form enough scale, leading to domestic sensor technology is low, not only and the price is high, it is difficult to competitive in the market.

Sensor industry in China and abroad comparison and analysis of the development of

Those gap sensor industry in China

Department of precision instruments, tsinghua university professor Dong Yonggui introduction, China is roughly from 1980 paid attention to the research of sensor technology in the future. After years of efforts, in the development of sensor research level is better. Technological progress in the transition, however, is not very ideal, a lot of sensor technology, it is the home of the laboratory research level is not very bad, but failed to make full use of, not into a mature product to market.

Sensor technology research, he says, need a long time, a sensor research and development, to six years to 8 years to mature, general Chinese companies can afford such a long period. Chinese enterprises more unbearable failure, and the risk of failure of the research is very high.

According to dong yong access to know about the situation in Japan, Japanese companies to support research and development, many not form products, but companies can afford, 10 can become as long as two to three items in a product line.

"We, by contrast, many enterprises are ready to take the things others existing." Dong Yonggui said that this approach is problematic, including ready-made, we always hope to introduce abroad have their own projects. "Is ready to fish, but catch a fish."

Compared to the relatively large instruments and equipment, sensor of investment is needed in the production process in general is not very big, so is suitable for small business investment. In this regard, China should be an advantage. However, if consider from another aspect, it's also a weakness.

A characteristic of industry is of sensor and sensor itself high technical content, but the price of single sensor is generally not high. The characteristics lead to a result, although sensor technology added value is high, but it is difficult to form a considerable rely on sensor output.

According to professor Dong Yonggui metaphor, sensor is a bit like the "medicine", in the traditional Chinese medicine itself function is very important, but the real scale also need to rely on the whole clothing agents. Foreign many sensors company once a breakthrough in some sensors, soon there will be a relevant measurement instrument is developed.

And, under the mechanism of China's patent protection, the key technology of sensor worked so hard in developed, often present a "trick" nature, be copied, it is hard to say clear, enterprises can also. Although there is also a MEMS sensor domestic enterprises, but are processing, maybe is myself to do the processing enterprise, the enterprise innovation system have a big problem.

In 2012, a domestic predecessors said at a conference in the field of sensors, career development is bad, why China sensor is lack of class leader to the state council, the field of research and development of long and significant degree is insufficient, itself is a small thing, is based on the physical phenomenon is found in decades, hundreds of years ago.

The scholar pointed out that this study very hard, actually have an acceleration sensor, for example, is used for seismic wave in the oil industry, is based on which the Soviet union put forward the principle of decades ago, but until the expert, after the break-up of the Soviet union to the United States has been applied to form the product.

"The more need to be whole, extensive cultivation areas, our gap." Dong Yonggui think, now the trend of the gap has widened further.

The next 5 years is the survival of domestic sensors?

Sensor industry development in recent years, China's overall scale expands gradually, significant applications in the automotive industry including sensor application in automobile tires, airbag sensor applications of the sensor application, chassis system, engine sensor in the operation management system application, exhaust gas and air quality control system of the sensor and the sensor application demand, ABS and the sensor application demand, vehicle security system and the sensor application demand, car alarm system and the sensor application demand, engine combustion control system and requirements, car positioning system, automobile sensor application and demand system of other sensor applications and requirements. In addition, China sensor also has a new application in other fields, such as industrial control field, in the field of environmental protection, in the facility agriculture, and other relevant sensors in the field of multimedia image application.

The sensor industry in China in 2014-2018 forecast and investment strategy research report, according to the sensor industry in China, though developing rapidly, but there are some unfavorable factors. Such as on the product technology industry foundation is weak, the chasm between science and technology and production, product technology level is low, the products lack, the enterprise product research and development ability weak. But on the other hand, countries continue to develop good sensor industry development strategy and policy, the rapid development of the whole machine system market, throughout the year of emerging technologies push also become the positive factors for the development of sensor network.
