It has been more than ten years since Bill Gates mentioned IOT in his book "the road to the future" in 1995 and mitauto ID (MIT automatic identification center) proposed the universally recognized concept of IOT in 1999. As a representative of the third wave of the world's information industry, IOT has attracted increasing attention worldwide and has become the focus of industrial policy support and investment in recent years

from the "2013 China IOT industry development annual blue book" (hereinafter referred to as the "blue book") released at the fourth China International IOT Expo held recently, since Wuxi put forward the concept of perceiving China in 1999, in the four years, from the central competent ministries and commissions to industries, provinces and cities, multi-point and multi-level IOT planning has been intensively introduced; In the past four years, IOT special funds at all levels have been launched, and a new round of IOT special funds is expected to double; In the past four years, all the first tier cities and more than 50% of the second tier cities in China have put forward the goal of building smart cities. It is preliminarily predicted that the market scale of smart cities will exceed 700billion yuan during the 12th Five Year Plan period and reach trillions of yuan during the 13th Five Year Plan period

however, as Wu Hequan, an academician of the Chinese Academy of engineering, said, China is the country that attaches the most importance to IOT in the world at present, but the practice of vigorously promoting IOT industry in many places seems to remain at the conceptual level, so there are some signs of overheating, which need to be treated calmly

the value of forming a three-tier technical architecture system

IOT is to make objects also have wisdom, so as to realize the communication between people and things, and between things. The characteristic of IOT is the superposition of knowledge, interconnection and wisdom that sense that the import volume is affected by the massive import of precious non-metallic minerals such as diamonds. Therefore, IOT is composed of three parts: sensing part, transmission network and intelligent processing

at present, the architecture of IOT is generally considered to have these three levels. The bottom layer is the sensing layer, that is, the sensing network, the middle layer is the network layer, that is, the network channel of data transmission, and the upper layer is the application layer

in the architecture of IOT, the perception layer is equivalent to human skin and five senses, the collateral layer is equivalent to human neural center and brain, and the application layer is equivalent to human social division of labor. "Blue book" figuratively said

the blue book points out that the perception layer is the skin and five senses of IOT, including QR code tags and readers, RFID (radio frequency identification) tags and readers, cameras, GPS, etc. its main function is to identify objects and collect information, which is similar to the role of skin and five senses in human structure. The network layer is the nerve center and brain of IOT, including the fusion network of communication and interconnection, network management center and information processing center. The collateral layer transmits and processes the information obtained by the perception layer, which is similar to the nerve center and brain in the human structure. The application layer is the social division of labor of IOT, which combines with the needs of the industry to achieve extensive intelligence. This is similar to human social division of labor, and ultimately constitutes human society

formation of standardization work framework

standardization is a very important work in the construction of IOT, which has a very important impact on industrial development. From the perspective of the market, whoever masters the standard will occupy the commanding height of the market. From the perspective of technology, on a standardized platform, some originally complex problems, such as equipment heterogeneity, will be solved easily

as liuhaitao, President of perception China IOT group, said, the idea of IOT application and standard promotion is to formulate the standards of common platforms and application subsets. The relationship between standard application, industrial key technology public relations and technology research is like the relationship between our left leg and right leg. Standard formulation, industrial promotion and application norms are promoted together like gears. Liu Haitao said that the formulation of standards is endless, and it will be formulated, modified and improved with the development of application and industry

in recent years, the standardization of IOT in China has developed rapidly, forming a good IOT standard working system, mechanism and environment. The state has created a favorable environment for the standardization of IOT from the aspects of policies and special funds. The national development and Reform Commission and the National Standardization Administration Committee, together with relevant ministries and commissions, have established a working system of basic standards + applied standards, and established more than 10 standards related working institutions of IOT. The standardization work framework of IOT has basically taken shape

operators become emerging forces

the development of IOT is bound to form a complete industrial chain. According to the classification of the blue book, the industrial chain of IOT should include three parts: the core industrial system represented by integrated circuit design and manufacturing and embedded system, the supporting industrial system represented by network, software, communication, information security industry and information service industry, and the application-oriented related industrial system represented by digital earth, modern logistics, intelligent transportation, intelligent environmental protection, green manufacturing, etc

among them, RFID and sensors are the foundation of the whole IOT industry. In terms of quantity, RFID and sensors are the tentacles of the whole network, so the potential demand is the largest. But at the same time, compared with other links, the entry threshold of this link is not high, and the average price of products has been falling all the way, so it will be difficult to increase revenue in the future. Judging from the current situation, RFID and sensor enterprises have high investment value in the medium and short term due to more industrial applications and increased government support. From the perspective of space, IOT operators and RFID have the greatest development potential

the operator of low temperature friction and wear experiment machine is an emerging sub industry, which is likely to form an oligopoly in the future. At the same time, the demand for system integration will be much higher than the current demand for telecommunications and interconnection. The blue book points out that the operation of IOT covers a wider range of fields, including transportation, new energy, power JG158 (2) 004 rubber powder polystyrene particle external wall external insulation system, finance and insurance, and intelligent buildings. At present, IOT applications are only used in separate industries and enterprises such as power, transportation, medical treatment, logistics, etc. According to the analysis, operators will be the link with the longest benefit cycle of IOT

at the 4th China International IOT conference, ye Lingwei, deputy general manager of China Mobile IOT, said that China Mobile attaches great importance to the development layout of IOT and has been building institutions nationwide since 2006. By 2012, China Mobile officially established a wholly-owned subsidiary, China Mobile IOT Co., Ltd

as the IOT company established by China Mobile, we have our own positioning, and our development goal is to base ourselves on the country and meet the service needs. Ye Lingwei said that the positioning of China Mobile IOT is first of all the supporter of IOT business services, providing users with efficient, stable and safe IOT dedicated networks, and creating an open access platform, capability platform and big data platform; The second is the provider of special chips and modules, which carry out cooperative research and development and joint promotion in the fields of communication modules, intelligent sensors, processor modules and open source hardware systems; Another is the promoter of IOT special products. For segmented industries, we cooperate with system integrators (SI) and application providers (ap/sp) to provide solutions

How Europe and the United States play with smart cities

as early as 2007, the European Union proposed and began to implement a series of smart city construction goals. The EU's evaluation criteria for smart cities include smart economy, smart environment, smart governance, smart mobility, smart residence and smart people. EU countries have something to learn from in improving transportation and promoting energy conservation and emission reduction

take Stockholm, the capital of Sweden, as an example, the city has made outstanding achievements in controlling traffic congestion. The city has set up 18 roadside monitors on the road leading to the city center, and has realized the automatic identification of all vehicles by using technologies such as radio frequency identification, laser scanning and automatic photography. With the help of these devices, the city will charge a congestion tax on vehicles entering and leaving the city center from 6:30 to 18:30 from Monday to Friday, thus reducing the level of traffic congestion by 25%, and reducing the emissions of room gases with high temperature and hardness by 40%

another example is Copenhagen, the capital of Denmark, the city of bicycles. In order to encourage citizens to use rail transit with the least carbon dioxide emissions, the city strives to ensure that citizens can use rail transit within 1 km of their homes through overall planning. Obviously, the traffic of 1 kilometer road also depends on bicycles with a deep mass base. In addition to building three bicycle highways and providing repair and other service facilities along the way, they also provide radio frequency identification or global positioning services for bicycles to ensure smooth travel through the signal system

the United States uses IOT to connect all urban resources. On January 28th, 2009, Obama, who just took office as president of the United States, met with then IBM president Palmisano Palmisano, a representative of business leaders. Palmisano formally proposed the concept of smart planet to the Obama administration and proposed to invest in the construction of a new generation of smart information infrastructure. In September of the same year, dibike, Iowa, and IBM jointly announced that they would build the first smart city in the United States

dibike has beautiful scenery, and the Mississippi River runs through the urban area. It is one of the most livable cities in the United States. With the goal of building a smart city, dibike plans to use IOT technology to digitize and connect all the resources of the city (including water, electricity, oil, gas, transportation, public services, etc.), monitor, analyze and integrate various data, so as to intelligently respond to the needs of citizens and reduce the energy consumption and cost of the city
