The impact of the Internet of Things on urban management

The impact of the Internet of Things on urban management is mainly reflected in the unified monitoring of urban security and the digital management of the city. The unified monitoring of urban security is based on the real-time remote monitoring, transmission, storage and management services of the broadband Internet. It uses broadband and 3G networks to network scattered and independent image collection points to achieve unified monitoring, unified storage and unification of urban security. Management, providing urban managers and builders with a new, intuitive, and visual-auditory management tool.

Currently, IoT technology has been used for urban security. The "electronic fence" independently developed by the Institute of Microsystems of the Chinese Academy of Sciences is a form of unified monitoring of urban security by the Internet of Things. This system has been applied to the Shanghai World Expo, providing 24-hour security protection for the 3.28 square kilometers of the Expo Park in the fenced area. Its role is as low as hundreds of security guards and police officers taking turns on duty.

The digital management of cities is based on key technologies such as geographic information system GIS, global positioning system GPS, and remote sensing system RS. It develops and applies spatial information resources to serve urban planning, urban construction and management, and serves the government. , enterprises, the public, and sustainable development information infrastructure and information systems that serve the population, resources, environment, economy and society.

The impact of the Internet of Things on personal life

The impact of the Internet of Things on personal life is currently mainly reflected in the expanded functions of smart cards and mobile phones. The functions of smart cards are mainly reflected in two aspects: electronic delivery and identity recognition. Shopping in shopping malls and supermarkets, seeing doctors in hospitals, taking various means of transportation, staying in hotels, eating in restaurants, paying various fees, etc., all consumption behaviors can be settled by swiping a card. In addition, access control cards, book borrowing cards, etc. also have identity recognition functions.

Mobile phones are not only communication tools, but have developed into information centers for work, study, entertainment, and communication that people cannot leave without. It will be possible for people to complete all their work, study, entertainment, etc. on their mobile phones. If you need a large-screen display, there are wireless keyboards and external devices such as monitors and printers in offices, homes and public places; if you go to the wild, there are portable external devices such as wireless foldable keyboards and monitors, and the positioning technology of mobile phones will be used anytime and anywhere. Delivers the precise location of the phone holder.

However, are the applications of the Internet of Things limited to this? The refrigerator at home is no longer just for storing food, it can also be a good "housekeeper". It will remind you when the food is insufficient; it will remind you when the food has expired; it can even help the owner collect recipes online. Smart refrigerators, smart washing machines, and smart TVs like this will all be part of IoT life.

The development of the Internet of Things is "big thunder but light rain"

Currently, we have only taken the first step towards the grand vision of "connecting things to things" in the Internet of Things. Our government also attaches great importance to the development of this field and has included it as one of the emerging industries supported by the state. Local governments have also launched special industrial plans to lay out the development of the Internet of Things during the "Twelfth Five-Year Plan" period. The construction of the Internet of Things is in full swing in various places, but experts point out that the current development status of the Internet of Things in my country is "big thunder but little rain". We can see from the following data:

Several major operators in my country in 2010 Its service revenue on sensor networks and RFID is about 300 million yuan, which is 0.03% of its business revenue. Even including the revenue from video surveillance systems such as Global Eye, it is only more than 3 billion yuan, which is only 0.3% of its business revenue. A little more. If the input-output ratio issue is further considered, the results may be even less optimistic. At present, most applications of IoT technology remain in specialized industry fields.

As an emerging market application, the Internet of Things also faces challenges from all aspects. The first is the technical challenge. At present, there is a lack of theory, technical architecture and standard system to integrate the virtual network world and the real physical world within a unified framework. Secondly, we also do not master core chip and sensor technology. In addition, the cost of sensors remains high, with more than 80% relying on imported chips, causing concerns about reliability, security and privacy. Finally, the overall technology is backward. For example, the backward RFID single-channel system needs to be upgraded in some application fields. At the just-concluded Internet of Things Expo, most of my country's Internet of Things companies are manufacturers of cards and equipment, and there are very few companies with independent chip research and development technology.

The Internet of Things is in its infancy in my country as a whole, and the industrial chain is complex and scattered. It is mainly a small-profit niche market with low concentration, instability, and lack of scale, resulting in high costs. Secondly, the industry's informatization level is low, the threshold and barriers are high, it is difficult to get involved at the high end, and the income at the low end is meager. Third, the IoT business model is complex, and operators are good at one-to-one service relationships, that is, one user, one terminal, and one bill. The essence of the Internet of Things is multi-point connections, involving a wide range of terminals and a huge number.

The popularity of the Internet of Things concept mainly stems from various government incentives and support policies. However, the development of the entire Internet of Things also requires technological innovation, expansion of the industrial chain, and of course, the most important thing is market demand. Only when the development of the Internet of Things truly brings convenience to people's daily lives can we break out of the specialized industry market to gain a broader market space and affect people's lives in an all-round way.
