As an important guarantee for railway passenger transport, water on high-speed trains has a profound impact on the comfort and convenience of passengers during their journey.

[0003] At present, water tanks of high-speed trains in my country are generally filled manually. Specifically, the high-speed train is stopped on the track, and the water supply workers pull out the water pipes arranged in the water wells between the tracks while passengers are getting on and off the train. After pulling them to the designated position, the outer and inner covers of the water filling port of the high-speed train are opened in turn, and then the water pipes are inserted, and the water valve is opened to start filling until the water is full. This manual water filling method is labor-intensive and time-consuming. It is easy to cause the high-speed train to be unable to be filled with water during the time when passengers are getting on and off the train, which in turn causes the high-speed train to be delayed, seriously reducing the timeliness of the high-speed train operation.
