The 2023 China International Fair for Trade in Services is currently being held in Beijing. On September 4th, the Fair for Trade in Services welcomed its first public open day. As the largest comprehensive exhibition in the global service trade field, the Fair brings together many new technologies and achievements from around the world in the field of service trade. How to build high-rise buildings in the future? How does the teacher teach? What will be the differences between sports and fitness in the past? How will technology change our lives? Today's question to the end, let's pay attention to the new technologies at the Service Trade Fair.

How can technology empower skyscrapers to rise from the ground?

Is it unbelievable that workers in Beijing, thousands of kilometers apart, can make tower cranes on construction sites in Wuhan work according to instructions with just a flick of their fingers? How does technology help skyscrapers rise from the ground? Let's take a look at the engineering and construction section of this year's Service Trade Fair together.

How will these "black technologies" at the Service Trade Fair change our lives? Reporter | Beijing | Technology

CCTV reporter Wang Feng: At the Engineering Consulting and Construction Services Exhibition, there is a device similar to a game simulator, which is actually a device that remotely controls a tower crane. The workers above are operating a tower crane at a construction site in Wuhan, 1200 kilometers away.

This independently developed tower crane remote control technology achieves remote control of the tower crane through 5G network, and the operation delay can be controlled within 40 milliseconds. In addition, this technology can also enable one operator to operate multiple tower cranes in a timely manner, and can achieve centralized remote control of up to 5 tower cranes.

Exhibitor Zhao Yanjun: Through this intelligent remote control method, we can solve the risks of personnel working at heights and improve construction efficiency. At present, the maximum number of tower cranes in China should be around 400000 units.

At this year's Fair for Trade in Services, the newly released ultra high rise BeiDou high-precision satellite positioning receiver is a new application of BeiDou navigation technology in the field of architecture. It has broken through the technical bottleneck of China's independent equipment for measuring the construction of super high-rise buildings, with a measurement height of up to kilometers, achieving full process data monitoring and correction under various complex conditions, and precise positioning at the millimeter level. At present, this device has entered the mass production stage and is being applied in some super high-rise complex projects in China.

Exhibitor Guo Haishan: Solved the bottleneck problem of high-precision measurement in the construction field, allowing major engineering technologies to be mastered by the Chinese themselves, forming our "Chinese solution" for high-precision measurement in architecture.

How can an aerial building machine build a floor in 4 days?

Remote control and precise measurement, technology's expertise in the field of architecture goes far beyond this. In the exhibition area of engineering consulting and construction services at the China International Fair for Trade in Services, reporters also discovered a new "artifact" of building construction - an aerial building machine. With it, the fastest time to build a floor is only 4 days. How was this achieved?

CCTV reporter Li Lin: In the manufacturing hub of Wuhan, Hubei, I am now standing at the top of an aerial building machine 200 meters above the ground. Although standing 200 meters above the ground, walking on it feels like walking on flat ground. On the broad platform, in addition to steel guardrails, there are also tower cranes, concrete spreaders, and material storage yards of all sizes, making it a modern factory.

Whenever the construction of a floor is completed, the traditional method is to raise the outer climbing frames and transport them manually or using tower cranes to the new floor, which is time-consuming and laborious. After using the "building machine", the materials and equipment used for construction can follow the "building machine" and directly "climb" to the new floor. So how did a giant object weighing 900 tons climb on its own?

Bao Zeding, Executive Manager of the Wuhan Yangtze River Center Project of China Construction Third Engineering Group Co., Ltd.: The entire platform of the building machine is a frame beam composed of Bailey pieces. The frame is supported by 12 pillars, which lift the beam up. When the pillars are lifted up, the beam moves upwards as a whole.

With a command, the staff operated the buttons one by one, and the building machine slowly lifted upwards. In just over two hours, the 900 ton building machine platform completed a 4.4 meter climb.

Bao Zeding, Executive Manager of the Wuhan Yangtze River Center Project of China Construction Third Engineering Bureau: Conventional climbing formwork, one floor every 7 days, under the same conditions, it is currently very common for us to achieve one floor every 5 days. Do it quickly, grab it again, and it can be achieved in 4 days.

Nowadays, "aerial building machines" are showcasing their skills on more than 20 skyscrapers across the country, and various new equipment is making our urban construction faster but at a lower cost.

How can technology empower driving training to make learning to drive easier and more efficient?

In addition to high-rise building construction, driving training also relies on technology assistants. This year's Service Trade Fair, a driving training school in Beijing brought a set of smart learning car systems. Let's take a look at how technology makes learning to drive easier and more efficient?

At the Supply Chain and Business Services Special Exhibition of the China International Fair for Trade in Services, the reporter saw that a driving training school in Beijing has launched a complete set of immersive intelligent driving training programs. In addition to achieving the teaching tasks of all subjects in driving training, it has also added scenarios such as dangerous situation simulation and traffic accident response. The light and shadow effects are realistic, with a strong sense of immersion, making learning to drive easier and more efficient, greatly improving the student experience.

Citizen Wang Qiannan: It is definitely beneficial for new drivers, as it allows them to truly experience the feeling of driving and increase their subsequent knowledge reserves.

This system not only serves new students, but also provides specialized safety driving solutions for experienced drivers. By simulating typical accident cases, enhance the driver's ability to deal with dangerous situations while driving.

Exhibitor Yan Wenhui: It covers hundreds of scenarios, including the accidents encountered in daily life. We have demonstrated through technology that when drivers encounter this situation in real life, they can avoid accidents and injuries. More experience leads to fewer lessons.

What new changes will occur in technology empowered education classrooms?

What are the new applications of technology in the field of education at this Service Trade Fair? With the support of the latest technological products, what changes will happen to teachers in preparing lessons, attending classes, and correcting homework?

CCTV reporter Wang Feng: At the special exhibition on education services, we discovered a black technology - the smart blackboard. I believe everyone may have such a memory. When I was in school, my geometry teacher held various rulers and drew geometric models very seriously. But now with this blackboard, everything has been omitted.

This smart blackboard combines AI algorithms, and through intelligent hardware such as smart pens, teachers can easily draw various standard geometric shapes on the blackboard, which not only facilitates teaching but also optimizes the listening experience for students. In addition, this smart blackboard is also equipped with multiple teaching systems.

Exhibitor Batu: For example, our mathematics subject tools and virtual experimental content in physical chemistry have greatly improved our targeted teaching in regular classes.

This personalized artificial intelligence operating system was also exhibited on site. Through this software, not only can we achieve personalized homework assignments for teachers, but the system can also intelligently correct 100 assignments within one minute.

Exhibitor Ge Ruyong: Not only does it help teachers greatly reduce the burden of correcting homework every day, but also the teacher can immediately know which students have a higher error rate and which questions in the homework are common errors.

How can technology empower sports and fitness activities?

Participating in sports and regular fitness exercises is becoming a lifestyle habit for more and more people. This year's Sports Services Special Exhibition at the Service Trade Fair also showcased some impressive new technological products. What changes will technology bring to our sports and fitness? What new tricks can fitness exercise bring? Follow the reporter to explore the truth.

At the Sports Services Special Exhibition of this year's Fair for Trade in Services, the equipment and facilities exhibited by various manufacturers are more digital and intelligent. Due to breaking the limitations of time and space, sports enthusiasts can also interact and exchange ideas with online sports experts.

Exhibitor Li Yize: The domestic environmental competition, surrounding Qinghai Lake and Hainan Island, will be moved online so that those who cannot attend the competition on site can also participate in it at their own homes. At the same time, as the race track becomes increasingly diverse, we will integrate many domestic scenic spots and beautiful roads into it.

With the deepening implementation of the National Fitness Plan and the Healthy China National Strategy, more and more people are participating in sports and fitness activities, and sports parks that integrate smart scenes are a major development trend in the future.

Exhibitor Xu Yuzhou: This is the most representative third-generation intelligent equipment in our sports park. Its instrument panel will display the current sports data, and the sports data will be transmitted to the backend of the sports park. Our trail is not just a healthy walking trail, but an intelligent one. The so-called intelligent trail provides a reference for data through facial recognition.

New comment: Donkey like "morale" limit pulls US debt "bomb" fuse hard to dismantle US | debt | morale

On the evening of June 1st, the US Senate passed a bill on the federal government's debt ceiling and budget, and the flame of the US debt bomb was temporarily extinguished at the last moment. The two parties in the United States have staged an extreme tug of war over the US debt bomb. Some experts believe that the US debt crisis is the result of the reckless politics promoted by the US dollar hegemony, and the underlying cause of this crisis is the highly polarized political system of the US. Since the end of World War II, the US Congress has adjusted the debt ceiling more than a hundred times. The recurring debt crisis will not only have a catastrophic impact on the US economy and people's livelihoods, but also continuously erode the value of US dollar assets such as government credit and US bonds, bringing significant and far-reaching impacts to the global economic landscape. 【
