Many enterprises talk about how the sensor industry will develop in the future. The ultimate goal of IOT is to realize the real-time replication of the physical world in the digital world, that is, the digital twin of the earth. At present, after more than half a century of development, Internet has basically copied the physical world to the digital world, but it has not realized the real-time reproduction of the physical world's natural environment and human environment in the digital world. At present, more data in the physical world enters the digital world through man-machine interface. As the only non-human interface from the physical world to the digital world, sensor is the most basic and important basic condition for IOT to realize the digital twin of the earth

as one of the three core technologies of IOT, the field where sensors are widely used is also the main battlefield of IOT applications. According to the latest statistics of relevant institutions, there are more than 22000 kinds of sensors in the world, which are widely used in all walks of life. The top three application fields in the world are: electronic consumption, industrial automation, automotive electronics; The field with the highest compound growth rate is medical electronics, with an annual growth rate of more than 30%; The most promising application field is smart city. The five fields of sensors also correspond to the five main battlefields of IOT: intelligent wear, intelligent manufacturing, car service, medical IOT and smart city comprehensive perception. With the improvement of large-scale technology, products and infrastructure (NB IOT/LORA) at home and abroad, the sensor and IOT industry is bound to usher in explosive development

with the wide application of sensors in IOT, the development of sensing technology and products in the future will be towards the intelligent sensing system with the integration of sensing, knowledge and connection; Realize multi-function detection through highly sensitive sensors; Data processing is realized by edge calculation; The data aggregation of sensing measurement system is realized based on wireless network. The main product forms include three categories: intelligent sensing micro system, intelligent sensing terminal and intelligent sensing platform. At present, the sensor center of Chongqing acousto optic Co., Ltd. of CETC focuses on three types of systems, making full use of the company's professional advantages in sound, light, electricity, force and magnetism, and carries out new intelligent sensor technology, sensor integration technology, artificial intelligence algorithm based on edge computing, sensor network technology Sensor based artificial intelligence algorithm, IOT platform architecture research, and IOT application technology research based on artificial intelligence

at present, China's sensor industry has local characteristics and is at a small, scattered and weak level as a whole. 90% of high-end sensors depend on imports. At the policy level, it is suggested to strengthen the top-level design and adopt the mode of sensing + industry. Because there are many kinds of sensors, complex technologies and wide applications, simply supporting a sensor is of little significance. We should drive the technology and industrial development of a series of sensors through some large industries. It is understood that at present, relevant national ministries and commissions are carrying out relevant work. At the industrial level: on the one hand, domestic sensor enterprises can target professional companies such as Sensirion, senseair, Goethe and Ruisheng, on the other hand, they can develop towards multinational companies such as Honeywell and Bosch with strong professional applications. At the level of technical products: strengthen the basic technology research of sensors, carry out the research of high-end sensors and intelligent sensing technology, avoid seeking quick success and instant benefits, and make full use of capital to introduce advanced technology and talents at home and abroad

the next decade will be a golden decade for sensor development

GU Rongxiang, chairman of Shaanxi IOT alliance and general manager of Xi'an Zhongxing measurement and Control Co., Ltd.

China's IOT industry has developed from the enlightenment and cultivation period in 2009 to the rapid explosion period in 2015, and has been accepted by most companies. In 2017, the development of Nb IOT technology and the promotion of Lora technology basically solved the problems of high wireless transmission cost and high power consumption. Driven by the strength of Huawei, Alibaba, and the three major operators of China Mobile, Chinatelecom, and China Unicom, China IOT has seen unprecedented and vigorous development in the two main areas of smart city and intelligent manufacturing. 2018 will be the first year of China's IOT industry and innovative applications. It can be predicted that China IOT will lead the world trend and development trend in industrial applications. There are three types of fixtures

IOT has three layers: perception layer, transmission layer and application layer. The sensing layer is the foundation of IOT, and most of the sensing layer is composed of various sensors. It can be said that without sensors and all kinds of smart sensors, there will be no IOT industry. In the field of intelligent manufacturing, the remote fault diagnosis of machines can not be separated from a variety of sensors; In the field of smart city and smart home, it is also inseparable from a variety of sensors, such as parking space sensors, manhole cover movement sensors, temperature and humidity sensors, etc. In a word, all kinds of sensors, especially wireless intelligent sensors, have been widely used in IOT

IOT applications have different requirements for sensors. There are four common aspects: first, environmental adaptability. That is to adapt to indoor and outdoor environment, underground environment, air environment, marine environment, desert environment, and harsh climate. Second, low power consumption. Because most signals need wireless transmission, the sensor must have low power consumption, and wireless transmission also needs low power consumption, which promotes the rapid development and application of MEMS sensors. Third, low cost. Because the demand for sensors is increasing, the world will need tens of billions or hundreds of billions of sensors in the future, so the requirement for cost is to be as low as possible. If the cost is high, there will be no market. Fourth, high reliability. Without stable sensor signal output, the data obtained by IOT and big data will be useless or even harmful

in order to meet the requirements of IOT for sensors, we must pay attention to the development of sensor industry. First, it is suggested that governments at all levels and major enterprises should pay attention to the research investment in the basic aspects of sensors and list sensors as one of the national key strategic directions. Second, the government should give preference to the sensor manufacturing industry in terms of finance, taxation and special preferential policies. Third, the upstream and downstream of the sensor industry should strengthen contact and communication, especially the end customers should actively apply the sensors made in China. Fourth, the government and investment institutions should increase investment in the sensor industry and improve the intensity of investment. Smart cities and intelligent manufacturing will need more and more sensors. The next decade will be the golden decade for sensor development. I hope we can seize the opportunity to make breakthroughs in China's sensor industry not only in applications, but also in technology and basic research as soon as possible

constantly improve the gold content of sensor technology

Wang Gang, general manager of Mike sensor Co., Ltd.

human pursuit of a better life is the source of the development of IOT. Economic prosperity provides the necessary material guarantee for the demand of IOT. The rapid development of technology, especially information technology, makes it possible for IOT to be applied on a large scale. At present, the application of IOT in the industry can be basically summarized into six application scenarios, which are smart city, smart home, smart industry, car service, smart wear and smart medicine. As the basic element of information perception, sensor is an important pillar of building IOT, which is indispensable in any IOT application. It can be said that the sensor market must be as big as the IOT market. Nowadays, in the rapid development of IOT, wireless communication technology and computer software technology have disappeared, but the progress of sensor technology is relatively much slower. Although this is a consensus issue, it still has not received due attention

IOT application scenarios are ever-changing, and the types of sensors are dazzling. However, the common requirements of its polyurethane bench must be focused on intelligence, miniaturization, micro power consumption and low cost. For low-cost, take pressure sensors and smart city scenarios as examples, such as urban water supply and drainage and fire monitoring applications. The price of available industrial pressure sensors is at least $15-25. For massive applications, the cost is completely unacceptable. Under the condition of strict cost requirements, it can only be used in limited or as a pilot project at present. Mike sensor company sees the huge future of IOT development. Two years ago, it was developing economical pressure sensors. The new production line invested and constructed has begun to take shape, and it plans to reduce the price of IOT pressure sensors to less than $5 within two years

for China's sensor industry, the overall scale is still very small, and the core technology is subject to foreign countries. It can be said that China's sensor industry basically survives and develops in the cracks. The vigorous development of IOT has brought infinite opportunities to the sensor industry. How to develop, we should do the following:

first, we should raise the development of the sensor industry to the national strategy and guide social capital to enter or invest in the industry

second, the government formulates preferential policies to cultivate and help sensor enterprises, especially private enterprises, to do large-scale

third, enterprises should pay attention to intellectual property protection. IOT opportunities will also attract foreign-funded enterprises, and infringement risks need to be prevented

fourth, enterprises should still strengthen technology investment and constantly improve the gold content of sensor technology

fifth, refine the industrial chain, strengthen the division of labor and cooperation, and make the industrial chain enterprises develop towards the hidden champion

sixth, through industrial funds, promote the merger of relevant enterprises, develop together, and become bigger and stronger

improve the overall solution capability of the sensor

Wang Qian, deputy general manager of Shaanxi Mobile cloud computing branch

with the development of IOT in more vertical industries, the sensor, as the core device of the basic sensing layer of IOT, has become the core foundation of the development of IOT. Miniaturization, intelligence, higher integration, lower power consumption and lower cost of sensors have become the future development direction. In particular, the trend of intelligence will enable the sensor to have richer data processing capabilities, support the edge computing and fog computing of IOT, and speed up the integration of IOT and AI

for the future development of sensors, there are three suggestions:

first, increase the scientific research investment in high-end sensors to realize the independent control of high-end sensors. More than 90% of China's high-end sensors rely on imports, which limits the comprehensive competitiveness of IOT. In the new international environment, domestic sensor enterprises used in wireless communication, network, radar, imaging and other fields should be steady, accumulate capacity, and realize the independent control of high-end sensor technology, which is related to China's future strategic position in the IOT and the value distribution in the global IOT field

second, we should give full play to the existing low-end sensor technology and cost advantages, accelerate the global market expansion, accelerate the increase of market share, and accelerate the commercial realization in the sensor field where we already have a leading edge

third, improve the overall solution capability of sensors and obtain greater value from the industrial chain. In practical application, with the upgrading of demand and the deepening of market expansion, the overall solution of IOT has been paid more and more attention. Traditional sensor enterprises only pay attention to the product supply in the field of subdivision technology, which limits the price on the industrial chain
