When the Games mascot "Jinwa" and the intelligent robot "Youyou" are accompanied by a 3D version of the "Luhe Supervision and Transportation Map" on the waves, technology and humanities in the Games on the field of play. This "crossing" is just a small scene of the Games, which is full of technology.

From security to logistics, from the ceremony to the competition, the opening of the Games is less than a week, has allowed people to see a lot of science and technology content of the small surprise. Jump out of the "sports students" perspective, if from the "science students" in the eyes of the Games, all over the Tianjin Games in all corners of the "black science and technology" and what?

Speaking back to the opening ceremony of the intelligent robots, people in Tianjin National Games to feel the shock of the opening ceremony of science and technology, at the same time, may also produce this idea: when can my family have a and "robot cat" "big white" as cute as the smart Robot? That day, may not be far away from us. The U-Partner robot, which appeared at the opening ceremony, is one of the earliest mass-produced products in the field of humanoid service robots in the world, and represents the cutting-edge level of the service robot industry.

And "Jinwa" together with the main torch of the Games, "Youyou" can only be regarded as a small show. It is understood that the height of about 1.3 meters of the little guy, in depth voice interaction, robot vision, autonomous positioning and navigation, automatic obstacle avoidance, motion control, robot bionic simulation and modular design, have made breakthroughs in technology progress, has won the 2015 GaoGong Robotics annual meeting "Golden Ball Award".

If "YouYouYou" really appears in our life, what can it do? The answer to this question was revealed at the 2017 World Robot Conference, where the new generation of "Youyou" demonstrated the "venue guide" and "shopping mall guide". "shopping mall guide", "intelligent office", "banking service", "hotel service", "education teaching", "intelligent office", "intelligent office" and "hotel service". "Education" and "Home Control" and other intelligent scene applications.

"YouYou" is particularly eye-catching, and the stage that sets it off - the Olympic Sports Center Stadium, known as the "water drop" - also uses the most advanced laser projection technology, which can show the audience a beautiful scene even in the rain. In the rain can also be presented for the audience "Tianjin eye", the sea river waves and other beautiful, shocking three-dimensional image. At the same time, "laser projection" technology also maximize the savings of human resources, according to the deputy director Gao Yan introduced, "small, refined, clever" way, through the sound and light effects to show the content, so that the number of actors compressed nearly 20,000 people.

"YouYouYou" and "laser projection" is still only give people visual pleasure, and the Games in the other "black technology", but to the athletes, the audience and journalists! Bring personal "security benefits".

Passengers who have experienced this year's Spring Festival will remember the face recognition system set up in many stations. And this time in Tianjin, face recognition system was first applied to China's large-scale sports competitions. Take the media village of the Games as an example, the staff will enter the picture information of the media personnel into the system beforehand to form a specific database. When the person holding the document walks through the security instrument, the monitoring probe will capture the face image and the library of data relative comparison, if the "brush face" failed, not only will be rejected, the image information will be stored, the default for the visitors or strangers, and be saved and uploaded to the National Games Village Security Center. This seemingly complex process, in fact, the entire implementation time only takes about 1 second.

A game of fewer than hundreds of people, more than ten thousand people almost at the same time in the influx or out of the stadium, the audience gathered and how to solve the evacuation, which has been plagued by large-scale tournament security staff of the problem. In the Games, the organizers through the "know Tianjin" big data population heat monitoring platform to make this problem solved. Relying on Tianjin Mobile's big data technology, "Zhi Xing Tianjin" can quickly "sense" the changes in the flow of people in a region in a short time, and on this basis, analyze and predict the various characteristics of the crowd.

In this year's Games, the "Know Tianjin" big data platform is dedicated to real-time population flow monitoring and early warning of the Olympic Sports Center, News Media Center, Tuanbo Lake venue, the Games Village and other important venues. Tianjin Mobile IT and operations support center responsible person introduced, monitoring area is divided into 200mX200m grid, through the detailed discrete calculation of population data, the formation of the monitoring area for the depiction of the "panoramic heat map". The organizing committee managers can show real-time monitoring site population density, distribution, historical heat trends and other important data for the public **** security, venue management scheduling, volunteer service points set up, trends in early warning to provide strong data support.

The majority of the audience in the Games for the newly constructed venues, will certainly be the first time to feel the "sense of the future". To host the fencing competition in the new campus of Tianjin Sports Institute gymnasium, for example, the roof structure using hyperbolic spherical tube truss structure, the maximum span of 75.6m, the maximum lifting weight of 86.25 tons, lifting is more difficult. In order to ensure the safety of lifting, the construction party and experts on-site demonstration, and the use of BIM (Building Information Modeling, Building Information Modeling) simulation construction technology, and ultimately determine the use of dual-machine lifting method, the successful realization of the structure of the roof.

The stadium ground using suspended sports wood floor, and the use of suspended pavement process, to solve the local deformation of the traditional wood flooring installation. At the same time, the wooden floor on-site sanding and painting, greatly improving the flatness of the wooden floor, providing a good visual effect for the TV broadcast.

Technology changes life, science and technology is also changing sports, these scientific and technological achievements in the use of sports events, has greatly changed the audience's way of watching the game as well as the athletes of the game, the future will be further integrated into the people's food, clothing, housing and transportation. As for what the National Games "black technology", please be careful audience in the field, in front of the TV computer screen slowly to find it.
