The development of car networking should be combined with the status quo of China's economy

On July 15, 2011, Mr. Liu Yunjie, Academician of the Chinese Academy of Engineering and Director of the China Unicom Science and Technology Commission, delivered a keynote speech titled “The Development of the Internet of Things and Car Connectivity” at a forum.

Academician Liu first discussed the development of the Internet of Things. The status of the development of the Internet of Things, the question is how to put forward. Our world has a concept. There must be many areas that need to be changed. One of these areas is our power system. Now our power system is actually 40% to 70% of the power system and it is not available to our users. The resources for oil extraction can only be 20% and 30%. In this financial crisis, there was no early warning and the information was so developed that it was not predicted. Will there be a similar crisis in the future. What is the next step in such a crisis? Is it energy or what? We must not make some preparations to deal with these situations. So in 2009, IBM proposed the concept of a smart earth. This concept should develop from the current Internet era to the Internet of Things. What kind of concept is this? It is to allow the most advanced technology to penetrate into the development of the national economy and to make our economy sustainable. This is the essence of the wisdom of the earth. What is the Internet of Things? Everyone should not regard the Internet of Things as another network. The Internet of Things is a comprehensive network of mobile networks, the Internet, and electronic networks. It extends from notebook networks and mobile phone networks to other areas, for example, extending into the soil. Into the car, the tentacles will be extended to each industry, extending to the automotive industry, transportation industry.

We heard some sensor networks, Internet of Things, and ubiquitous networks. Everyone knows that the Obama administration, a network based on sensor networks as the core, and a sensor-centric network based on the wisdom of the Earth, is another crucial part. Last year, the European Union also formulated the European Union’s plan for the development of Internet of Things. It is necessary to ensure that the European Union has a leading position in the development of the Internet. Japan and South Korea have also formulated a national development strategy. Our country also attaches great importance to the Internet of Things from Premier Wen Jiabao and General Secretary Hu. The fields of application are ubiquitous, agriculture, intelligent transportation, smart grids, and medical care. The areas we are talking about today are related to the Internet of Things. This is the role of the Internet of Things in intelligent transportation. Intelligent transportation is to solve two problems. One is security. The number of deaths caused by traffic accidents in the world every year is 700,000. Our country is about 1/10. What a big loss this brings, and how many families bring misfortune, we Financial losses in 2009 were more than 90 billion. Another problem to be solved is traffic congestion and energy consumption. The losses caused by energy consumption and traffic congestion are very large. As a result of such a large loss, the U.S. statistics show that as a result of traffic accident losses, as much as more than 70 billion U.S. dollars a year. The blockage of the three main roads in Beijing is very powerful. If this problem is not resolved, it will restrict the normal lives and work of our common people. In the area of ​​intelligent transportation, we have always made a fuss about the use of smart traffic in the red light. Now that we are working on the car, we have some early warning information before the car fails. We must make a fuss about this area. As for the EU’s research on smart driving, the United States is also investigating the interaction between vehicles and road infrastructure. Japan’s intelligent transportation system has been heavily invested in the development of car networking. This is the EU experience in the study of smart cars, including some of the standards they set, including the organization of the ISO in the development of car networking. Car networking is definitely not an industrial idea. The top-level conferences are now studying the problem of car networking. The problem of car networking has attracted the attention of the academic community. To solve these problems, if these problems are not solved, this society cannot continue to develop. Their research includes the detection of roads, the organization of networks, the commonality between cars and cars, and the communication between cars and cars. There is now WCDMA, through a network, from this car to that car, and it is not like that. The problems that need to be solved are security information problems, and some are network problems. Now these issues are being studied. U.S. car networking attaches great importance to standardization, and the relevant standards have been formulated. To do this, they must first formulate unified standards for the industry. However, the problem they solve is three. The EU and the United States are all the same. The solution to the problem of car networking is three problems. One is the security issue, the other is the green issue, and the third issue is the issue of intelligence. This goal is very clear.

This is a collision problem at the intersection. This is a principle. Through the lower right corner of the map, you can see how the car and the car collide. How to stop it? There are equipment on the roadside. Calculate the danger of each car. It will automatically control your car and avoid vehicle collisions. This is the situation of Japan's intelligent traffic. This is done from all aspects of society. These are the well-known companies that are involved in the research of smart car networking. We can look at the situation in Japan. How many associations pay attention to this field and we have a lot of people to do this work. In our country, many departments have a monopoly. You can't do it. He can't do it. This is something in my department. Since it is fighting for this matter, whether it can be managed or not, it is not important. The key is that this area does not want others to participate. To do this right now requires the power of the whole society, not something that a department can do well. The electronic chamber of commerce organizes this conference. I think it is very meaningful. I hope that such associations and chambers of commerce can do this together.

Let's take a look at what the industry is doing. The United States General Motors is doing the concept of car networking, its goal is to smart driving, to apply all of the global navigation. In October of last year, Google launched a smart car that was driven by people. It measured 80 kilometers of this road, and it exercised 80 kilometers. Intel will also launch smart driverless driving. Some people may think that the automobile is a matter of our auto industry. Why did the software industry do this thing? Is it right? We all know that high-end cars, 50% of the cost is the cost of IT, the cost of electronics, so they do cars, which is taken for granted. These companies do not have these concepts. These are some of the ideas of our country in the 12th Five-Year Plan. We have formulated such a plan for highways, important road sections and bridges, including railways and waterways throughout the country, and integrated the intelligent transportation network into the 12th Five-Year Plan. among. In the case of our country, China Unicom, I learned a bit about using WCDMA to establish cooperation agreements with Geely and BYD. I think this is very necessary, but this is only the first step. What is the most important thing? When I participate in the traffic management system in Beijing, the most important thing is to determine the operating status and operating speed of each vehicle, where to start from wherever it is, and to process and analyze these road conditions in the computer behind the scenes. How many cars are on each road, the value of this intelligent transportation is much greater than the value of your phone call. If this part is done afterwards, the back-end data processing, cloud computing, and the development of intelligent transportation networks and car networking are making great use. This is not just hype, but it is real and real, and we urgently need to solve problems in real life.

The key technologies to be solved by Vehicular Interconnected Vehicles are one of the key technologies of the vehicle, including the collaborative technology of the car network information, including some standard issues. These standards and systems are all needed to be solved. There is also a problem that we face some challenges in the Internet of Things and car networking. In this aspect, we are not very capable in terms of technology. Each mid-to-high-end car has 300, 400 sensors, and most of the high-end sensors are imported. of. How is the price cheaper and the performance more intelligent? These are what we need to do. These things, each department needs to integrate strength, need to break the industry barriers, in the process, also need to pay attention to security and privacy issues.

The Internet of Things is also good, and the Internet of Cars is also good, but we often see it as a frame too much, forming a big industry, resulting in great benefits, this is very important, but also inevitable, but I think it should be how to do What? It should be more integrated with our national economy. What are the major problems that we need to solve in the car networking and transportation areas? These problems, if we can solve these problems through innovative technologies, the opportunities for our Internet of Things and car networking are here. Inside, Academician Liu mentioned last.
