A new round of development of IOT accelerates the annual growth rate of the sensor industry is expected to exceed 35%

Guide: the total output value of China's IOT in 2010 was about 190billion. It has exceeded 360billion in 2012, with an annual growth rate of nearly 40%. It is conservatively estimated that the growth rate of core segment industries (such as sensors) in IOT will maintain a compound annual growth rate of more than 35% in the next three to five years

recently, there have been frequent voices about the guidance on the development of IOT industry in China, and this policy will be supported by relevant fiscal, tax, finance, investment and other policies. The industry has expected that China's IOT industry will enter a new round of accelerated development

IOT, also known as sensing, was first proposed at the mobile computing and networking International Conference in 1999. At present, it has become one of the industries with the most development potential. In the past 2012, the scale of China's IOT industry market reached 365billion yuan, and it is predicted that it will exceed trillion yuan in 2017

the output value of some sub industries has exceeded 100 billion

the essence of IOT is to use various sensing technologies (RFID chips, sensors, etc.) to connect different entities through various communication means (wired, wireless, satellite communication, etc.), so as to realize instant information sharing, remote monitoring, automatic alarm and other functions. With the development of modern sensor technology, embedded system technology, communication technology, big data technology and so on, IOT has achieved great development in key technologies such as data acquisition, transmission, processing and so on. Zhi ----- Professor Huang Junqin of Kaohsiung University of science and technology can use transportation, intelligent electricity, intelligent security, intelligent medicine and so on. In the next three years, IOT also has broad prospects in industry, agriculture, environmental protection, food safety and government functions

since 2009, the central and local governments have given a lot of support to the IOT industry in terms of funds and policies. In 2012, the Ministry of industry and information technology formulated the 12th Five year development plan of IOT, which focuses on cultivating 10 clusters and 100 backbone enterprises of IOT industry, so as to realize the collection of upstream and downstream enterprises in the industrial chain and the integration of industrial resources

under the cultivation of policies, the IOT industry has been in a state of rapid development in the past two years, and the output value of a number of segmented industries has exceeded 100 billion. In 2010, the total output value of China's IOT was about 190billion. It has exceeded 360billion in 2012, with an annual growth rate of nearly 40%. It is conservatively estimated that the growth rate of core segment industries (such as sensors) in IOT will maintain a compound annual growth rate of more than 35% in the next three to five years

the sensor industry has the largest potential demand.

IOT mainly includes three layers of structure, namely, the sensing layer, the network layer and the application layer

the perception layer uses various sensors to reflect the characteristics and states of the real world, and digitizes the obtained information; The transmission layer transmits the information obtained by the sensing layer through the interconnection, wired and wireless communication networks; The application layer uses cloud computing, data mining and other technologies to quickly process massive amounts of information and obtain corresponding services according to the actual needs of users

at present, China has a good information network and transmission foundation, and the technical level of both the three major operators and system equipment manufacturers is at the world leading level. The sensor and chip manufacturing and integration in the sensing layer are relatively weak, while the massive information processing technology and industry application services in the application layer are also relatively weak. In the two-year IOT development special fund support project with abnormal 201 hammer return, it is involved in the application of RFID, sensor technology, transmission technology, data mining, intelligent transportation, intelligent agriculture and other sub industries. It is expected that the future policy will still be in transportation Some support will be given to the application fields of electric power, medical treatment, circulation industry and other industries, but the greatest support is still in the basic industries such as sensors, RFID chips and system level chips

as the end of the whole IOT, the sensor has the greatest potential demand. From the perspective of the global sensor industry, Europe, the United States, Japan and other countries have a good technical foundation, and the upstream and downstream supporting facilities are mature, and have formed a complete system. Many manufacturers have achieved large-scale production, almost monopolizing the high-precision, high-end sensor market. The domestic sensor technology foundation is weak, lack of independent intellectual property rights, and the localization rate of raw materials is low. Although there are a large number of enterprises engaged in the research and production of sensors, the key core technology of high-end sensors has not yet made a real breakthrough. Its products mainly meet the needs of the middle and low-end market, and almost 100% of high-end products are imported from abroad. The huge dependence of the domestic sensor industry on imports has become the bottleneck of the development of IOT in China. Only domestic enterprises realize the localization of sensors can improve the overall strength of the whole industry and accelerate the rapid development of IOT industry

high end sensors are at the critical point of high growth

domestic enterprises have occupied cost and technical advantages in mature sensor products at present. In the field of high-end products (photoelectric transmission to better serve global customer sensors, infrared sensors, speed sensors, acceleration sensors, GIS sensors, etc.), domestic enterprises have broken through the technical threshold and are in the early stage of promotion. Once they successfully break through the market, Will usher in another high-speed growth

due to the high professionalism of sensors, in addition to the international first-line manufacturers Honeywell, Bosch, Italian semiconductor, MEAs and other companies with relatively comprehensive sensor categories, other companies basically focus on a specific segment. For example, ABB's main sensor products are applicable to the power industry, Freescale products are in the automotive electronics and consumer electronics fields, and Vishay is concentrated in the industrial weighing field. The same is true in domestic companies. Hanwei Electronics' products are mainly gas sensors, and Xiaogan Huagong Gaoli's products are mainly temperature sensors

in terms of gas sensors, the market capacity of China in 2011 was about 11million. As the leader of domestic gas sensors, Hanwei electronics sold 6.5 million, with a domestic market share of about 60%. The company adheres to the development strategy of focusing on professional market segments. Through years of efforts, it has mastered semiconductor sensors, catalytic combustion gas sensors, electrochemical sensors The production technology of infrared optical gas sensors and mass production is the only enterprise in China that can produce the above four categories of gas sensors, and the gas sensor technology remains the leading in China. Its products and solutions have been widely recognized by the market and are mainly used to detect and monitor combustible gases, toxic and harmful gases and special gases. The company said that it would deeply cultivate the gas sensor market and vigorously cultivate and expand the market in the field of gas monitoring. It is expected that the sensor market in the gas field will have a compound growth rate of more than 15% per year in the next three years. As the gas sensor accounts for less than 3% of the whole sensor market, and the development space is relatively limited, the company is not satisfied with only expanding in the field of gas sensors, but also exploring the temperature and other sensor markets. In recent years, the company has developed and produced pyroelectric sensors. In 2011, the sales volume has reached more than 3 million, and the contribution income is about 5 million yuan. If the business expansion is relatively smooth, it is expected that the growth of China's plastic machinery industry has ushered in a golden period of Kemen growth and rapid growth, and it is expected to achieve more than 100% growth in the next few years

in terms of temperature sensors, Huagong Gaoxin science and Technology Co., Ltd. is the largest manufacturer in China. At present, its production capacity of temperature sensors is more than 700million, and its domestic market share in the field of household air conditioning sensors is expected to be 70%. The company has established national scientific research institutions such as the sensitive ceramic engineering research center of the Ministry of education. Its products are internationally competitive, and LG, Samsung, Midea, Gree and other well-known enterprises at home and abroad are the core customers of the company, As the demand for sensors in products such as variable frequency air conditioners is times that of traditional products, it is expected that sensors will maintain a stable growth of 10% - 20% in the home appliance market in the future. Through technical research and development in recent years, the company has expanded to the high-end market and actively entered the automotive sensor market. As the price of automotive temperature sensors is about 6 yuan, which is much higher than home appliance sensor products, if the company's products can pass the certification of high-end brand automobile manufacturers and form batch shipments, its profit prospects will be very considerable

in the field of high-end sensors, China is in the stage where the technical threshold has been broken and the market threshold is about to be broken. Some companies have made some breakthroughs in the fields of photoelectric sensors, infrared sensors, speed sensors, acceleration sensors, GIS sensors and so on, such as the acceleration sensors of Suzhou gutechnetium and the thermal sensors of AVIC electric measurement, but they have not yet formed a scale. With the support and promotion of national policies, China's sensor industry will grow at a high speed
