Development Trends of China’s Internet of Vehicles
In the government work report of the two sessions in 2012, the Internet of Things was once again mentioned as a strategic emerging industry. The Ministry of Industry and Information Technology published the “Twelfth Five-Year Development Plan for the Internet of Things” on its website. This is the first Internet of Things plan in the history of my country’s five-year plan. The plan clearly states that the Internet of Things will be used in smart grids and smart transportation , Smart logistics, finance and service industries and other fields took the lead in key deployments.
As an important application of the Internet of Things in the automotive industry, the Internet of Vehicles has been listed as a key project during the national “Twelfth Five-Year Plan” period. At present, the Ministry of Industry and Information Technology is starting from various aspects such as industrial planning and technical standards to increase support for in-vehicle information services to promote the full deployment of the Internet of Vehicles industry.
As of the end of 2011, more than 500,000 new cars nationwide had pre-installed in-vehicle information service terminals. The industry predicts that by 2015, there will be at least 40 million automotive mobile Internet service technology users. Calculated on the basis of an average consumption quota of 1,000 yuan per user per year, the market space of the Internet of Vehicles industry by 2015 will be about 40 billion yuan, and the related output value will be as high as 100 billion yuan, and China is also expected to develop into the largest in-vehicle information service industry in the world. Market.
Internet of Vehicles applications still need to overcome environmental problems
At present, the biggest dilemma in the development of the Internet of Vehicles lies in the grasp of the surrounding environment. Judging from the current application situation, our current car networking related products have solved the problems in the car very well. In fact, the problem between cars and people has been better resolved. When we get out of the car door, we will find that the current problems of cars and cars, cars and roads, or cars and the environment are not well resolved. Therefore, the development of the domestic Internet of Vehicles industry is still at a relatively early stage. Although there are many GPS-based positioning technology and 3G mobile communication applications, most of them are independent, and various resources have not been effectively integrated. In the future development, policies, funds, and technologies involving a wider range of fields still require the joint efforts of government departments, automobile manufacturers, ITS transportation integrators, and related technology manufacturers to step through the thresholds step by step.
From a technical point of view, the Internet of Vehicles is divided into two technical parts, namely RFID technology based on in-vehicle applications, and ITS intelligent traffic management technology based on traffic management. However, from the perspective of the system architecture of the Internet of Vehicles, in addition to the above-mentioned in-vehicle application-based RFID technology (perception layer) and TS intelligent traffic management technology (application layer), there is also communication technology (network layer), which is to realize the Internet of Vehicles An essential component for a perfect job.
All in all, after solving the above problems, the Internet of Vehicles application will usher in a faster development period. We can imagine that in the future, urban traffic will become faster and more travelled without much breakthrough in road construction. Efficient.
Conclusion
The in-vehicle Internet of Things is an emerging field with huge development potential. It can make people’s daily life more closely integrated with computer technology and Internet technology, enhance traffic safety, improve urban traffic efficiency, and provide various location-related information services. In recent years, the in-vehicle Internet of Things has received great attention from academia, industry, and government departments, and relevant industrial and technical standards have been put on the agenda. However, for different applications and different environments, there are still many problems that have not been properly resolved. People believe that in the field of in-vehicle Internet of Things, more and more in-depth research will be seen, and at the same time, in-vehicle Internet of Things technology will be able to quickly get out of the laboratory and put into practical application.
