Primary school students enter the university campus to feel the traffic "past and present"
"The Beijing-Zhangjiakou Railway runs from Fengtai, Beijing to Zhangjiakou via Badaling. It is extremely steep in the Guangou section. Mr. Zhan Tianyou creatively built the'herringbone' railway and introduced this foreign high-horsepower locomotive, the Marais locomotive, which uses dual locomotives. Traction solves the problem of transportation power of the Beijing-Zhangjiakou Railway." Yesterday, Beijing Jiaotong University Transportation Technology Week was officially launched. Dozens of pupils from the Primary School Affiliated to Jiaotong University walked into the university campus to learn about the "past and present" of transportation.
Yesterday morning, the editor of Education Roundtable (WeChat public account: jiaoyuyuanzhuo) saw in the transportation equipment teaching hall that a college student volunteer was telling the story behind the Marais locomotive to the pupils. The pupils listened very carefully and deeply. Moved by the spirit of Zhan Tianyou.
On the other hand, the Beijing Jiaotong University Che-Road collaborative autonomous driving simulation sand table also attracted many audiences.
The sand table simulates the operation of autonomous vehicles on urban roads in a vehicle-road collaborative environment.
According to Professor Wang Jiangfeng, the person in charge of the sand table, the sand table mainly demonstrates two scenarios, one is the automatic driving of a bicycle, and a tracking intelligent networked vehicle relies on high-precision electronic maps and vehicle positioning systems to drive around the sand table road. In the process of traveling, the vehicle's lidar detects obstacles ahead and will automatically avoid it.
The other is the vehicle-road collaboration scene. The intelligent networked vehicle receives the information broadcast by the intelligent traffic light through wireless communication, and judges whether to pass according to the real-time traffic light signal at the intersection. The red light intersection automatically stops and waits, and automatically starts to pass when the signal light turns green. Intersection.
"Single-vehicle self-driving vehicles rely on the vehicle's own sensors, which require a high degree of intelligence and a limited range of observations. The vehicle-road collaboration technology installs various sensors around the road on which the vehicle runs, which is equivalent to outside the vehicle. Countless eyes were installed. After that, through communication technology, various information on the road was informed to autonomous vehicles with a certain degree of intelligence, helping the vehicles to determine whether they need to stop, accelerate, turn, etc." Wang Jiangfeng used vivid language to say Primary school students introduced the working principles of single-vehicle autonomous driving and vehicle-road collaborative autonomous driving in a simple and simple way.
And in the National Virtual Simulation Experiment Center on the third floor of the eighth teaching building, an aircraft is "settling" at the Capital Airport. Students majoring in civil aviation transportation at Jiaotong University use the airport tower control simulator to "dispatch" the aircraft. On the big screen, The whole process of the aircraft from the parking stand to the taxiway to the runway and finally into the air is clear at a glance.
It is understood that "Innovation leads the support of science and technology, and accelerates the construction of a strong transportation country"-2021 Beijing Jiaotong University Transportation Science and Technology Week starts from May 22 to May 28 and lasts for 7 days.
The theme of the event is "Popularize scientific knowledge and help the country become a strong transportation country". It will focus on the development of a century-old transportation development retrospective, transportation science and technology exhibition, excellent student work science and technology exhibition, transportation original science works contest, transportation science popularization series lectures and exhibitions, etc. Events.
At the kick-off meeting, Lin Qiang, deputy director of the Science and Technology Department of the Ministry of Transport, and Yu Zujun, vice president of Beijing Jiaotong University, jointly unveiled the science and technology activity week and issued letters of appointment to 9 consultants of the Transportation Science Museum.
Lin Qiang said that during the centenary of the founding of the party and the important historical intersection of the "two centenary years", the coordinated development of technological innovation and scientific popularization in transportation will be promoted, and the construction of a powerful transportation country will be promoted.
According to Yang Hao, consultant of the Transportation Science and Technology Museum, the Transportation Science Museum fully embodies the school’s characteristics of “love the road and serve the country, and “knowledge and do” unify the value of “action””. In the future, it will further play its leading role in science and technology and promote talent training through technological innovation. , To help build a strong transportation country.
The holding of this transportation science and technology activity week will further promote the spirit of science, popularize scientific knowledge, improve the scientific literacy of the whole people, promote the coordinated development of scientific and technological innovation and scientific popularization, and help build a strong transportation country, so that the achievements of scientific and technological innovation and scientific popularization activities will truly benefit the majority of teachers. Health and the public.
