"what key role do platform doors play behind the safe operation of the subway?" "who commands the 'opening' and 'closing' of the platform doors?" on september 6, beijing-hong kong metro went to the primary school affiliated to capital university of economics and business in fengtai district, beijing, and conducted the first class after the launch of the subway steam interdisciplinary education project, bringing a wonderful "platform door exploration" course to more than 30 students present.
the reporter learned that steam is a combination of the first letters of the five english nouns science, technology, engineering, art, and mathematics. it is an educational concept that emphasizes practicality and interdisciplinary integration, and is increasingly receiving attention from education circles in various countries.
in july this year, beijing-hong kong metro launched the first steam interdisciplinary education charity project in rail transit. the project was independently developed by beijing-hong kong metro.integrating professional knowledge of subway vehicles, communications, signals, electromechanical, rails and other engineering, the school provides scientific enlightenment to young people of different ages in the fields of rail transit-related engineering, technology and other fields through subway steam courses, subway engineering simulation teaching aids, subway science picture books and other forms.
"why can the use of platform doors expand the usable area of the platform?" "what devices can help the platform doors to open and close smoothly?" at the beginning of the activity, as one question after another was asked, the students were full of curiosity and started a journey of exploration under the vivid explanation of the "subway teacher".
during the course, the volunteer lecturer gradually explained the engineering principles behind "how the platform door is precisely synchronized with the subway car door" and "the anti-pinch function of the platform door", and through a series of questions and quick answers, the students had a new understanding of the structure and function of the subway platform door. under the guidance of the volunteer lecturer, the students also worked with their partners to build the "platform door model teaching aids" that were part of the course.
at the end of the course, the volunteer instructor invited students to come on stage one by one to show their construction results. as the gears turned, the door of the model platform slowly opened. the students witnessed the application of mechanical principles in reality and felt the charm of mechanical design.
yang ling, public relations manager of beijing-hong kong metro, said that in the future the project will be introduced to more schools and communities to popularize rail transit knowledge, cultivate students' innovative thinking and interdisciplinary practical ability, and allow more young people to understand the operating principles of rail transit and pay attention to and participate in the development of urban transportation.
