Let's talk about IOT: opportunity or foam

since mit1999, when the concept of AutoID was proposed, that is, the information of items was automatically collected to the central information system through wireless communication technology, so as to realize the identification and transparent management of items, after the redefinition of the concept of smart earth in ibm2008, this connection was expanded from simple items (commercial products) to fields closely related to people's lives, such as electricity, railways, bridges, tunnels, buildings, etc. So far, the integration concept of human society and physical system emphasized by IOT has initially appeared

on March 20, at the third industrial forum of Beihang and Africa, lecturer Zhang Youguang concluded that according to the concept of IOT defined in IBM smart earth, it mainly involves three technologies - comprehensive perception, reliable transmission and intelligent processing

comprehensive perception refers to capturing external information through sensor, GPS, RFID and other technologies. Reliable transmission refers to the integration of various communication networks and interconnection network technologies to transmit signals. Intelligent processing is to analyze and process a large amount of cross regional and cross industry data through cloud computing, fuzzy recognition and other technologies on the basis of signal capture and transmission. At present, around IOT, more work is also focused on the formulation of unified standards by various institutions and future development plans. Those manufacturers who follow the idea of increasing the capacity of IOT, especially lithium hexafluorophosphate and diaphragm, are also mainly focused on signal sensing and transmission

future opportunities of IOT

teacher Zhang Youguang said that according to the Research Report on the current situation and investment opportunities of China's IOT industry launched by the relevant market research center, in the next three years, China's IOT industry will take the lead in the popularization of smart electricity, smart home, digital city, intelligent medical treatment, vehicle sensors and other fields, and the total output value of the five fields will reach 50billion

this is a huge industry, and it is another development opportunity for China to follow the world's footsteps in the first and second information revolutions. At present, the three major domestic operators have launched corresponding products and plans around the concept of IOT. At the enterprise level, IOT technology has also been introduced into the fields of perimeter alarm and automatic train identification

IOT can develop in a wide range of fields in the future. Here is a brief description of smart electricity and smart medicine

the so-called smart electricity simply means that the power with artificial intelligence cannot be supplied without phase interruption. It can integrate and allocate power supply and demand in real time and flexibly, and achieve the best energy-saving power management. Smart electricity includes power transmission and distribution networks, advanced electronic meters, various energy storage facilities, information analysis and control software, circuit safety protection mechanism, etc. In addition to more flexible and effective allocation of power supply and demand, smart electricity needs to use the real-time power consumption information provided by advanced electronic meters to change users' power consumption behavior patterns and save electricity; In addition, through differential electricity prices, we can further reduce peak power consumption and avoid huge investment in the construction of additional power plants. Therefore, smart electricity is beneficial to both power supply and demand, and is conducive to comprehensive and substantial energy conservation and carbon reduction

intelligent medicine includes telemedicine consultation, telemedicine education, the establishment of multimedia medical and health care consulting system, etc. Intelligent medicine establishes a brand-new connection between medical experts and patients, so that patients can receive consultation and treatment and nursing under the guidance of remote experts in their original place and the original hospital, which can save doctors and patients a lot of time and money

deployment of IOT in the three major operators

Application of IOT technology in real life

from a global perspective, the development of IOT is still in its infancy. China started early in the development of this field, and the development of technology and standards is basically synchronized with the international level. The National Natural Science Foundation of China, 863 and 973 have all given more support to the IOT industry. But at the same time, the development of IOT in China still faces this important problem - the lack of leading enterprises

the challenges facing IOT put forward requirements for organizing this year's peak shift production.

according to the industrial development trajectory, an emerging technology from the laboratory to specific applications cannot be without the traction of mainstream enterprises, which is the weakness of IOT technology in domestic development. Mr. Zhang Youguang said: at present, there is a lack of leading enterprises of IOT in China, and most of them are small, miscellaneous, scattered, and lack of core technology

IOT system architecture

he said that at the beginning of the establishment of the China sensor network standard working group in October 2009, more than 70 enterprises participated, including state-owned enterprises such as China Mobile, private enterprises such as Huawei, and even multinational enterprises such as Nokia and Cisco. However, most of these participating enterprises are still in a state of excitement, so we don't know how to participate, The standard setting group has no precedent to follow. Even if Broadcom, which launched ADI with smart electricity meters and integrated a variety of wireless transmission standard single chips, will greatly increase the proportion of exports to emerging countries, it is known as the pioneer of IOT industry. How to deploy and carry out IOT in the future is only in the exploratory and waiting stage

technology development curve

in addition, in terms of market cultivation, no matter how good the concept is, it needs to be recognized by end users. At present, the current situation we are facing is that users are still unfamiliar with the concept of IOT, and still need guidance and advice from the industry. It can be said that the field of IOT is absolutely the coexistence of opportunities and challenges. Choosing the appropriate entry field and the appropriate entry point is the top priority for the development of enterprises and industries

four stages of IOT development

hazy stage (around 2000): only the embryonic form and long-term development goals

growth stage (around 2010): an important stage of technology research and development. The United States and Europe are investing heavily. China plans to invest 3.86 trillion yuan before 2020

transition stage (around 2020): an important stage of scientific experiments. From theory to practice, IOT will carry out detection and pilot in a certain range, analyze and process a large amount of data in the experiment, and improve the technology. IOT commercial will initially see scale and benefits

mature stage (after 2020): comprehensive promotion and application, with the largest investment and the most significant benefits, covering the whole society and becoming a new growth point of the world economy
