Advanced technologies have made the newly-constructed subway Yanfang (YF) line smart, which had a trial run without passengers in the Fangshan District of Beijing on 15 Dec.The YF line is China's first completely-automatic subway with the Chinese-owned proprietary intellectual property rights.
On this automatic subway line, "drivers" on the trains do not need to operate the devices; they just monitor the devices and the routes where th trains run.
In fact, the real drivers are the operators at the control center of the subway."The unmanned driving technology will largely cut the time used for operation, shortening it by 15 seconds for each station covered," said Lyu Aiguo, program manager of the signaling system of the YF subway line.
Inside the trains, all the systems, including signaling, telecommunication, monitoring, air-conditioning and lighting were produced in China.
The lighting system can adjust the luminance in the trains according to the outside conditions, while the air-conditioning system is remotely-controlled.
"Different from other subways, there are three-on-one backups to guarantee the proper operation of the YF line's central control system, and the other devices inside the trains also have one-on-one backup.
That is to say, if one device breaks down, the train can still move safely," said Lyu.When the subway line stops operation at night, the automatic cleaning and charging systems will start working.
The trains then leave the parking lot and run automatically the next day.The YF subway line will officially start its operation by the end of December.The YF line, totaling 14.4 kilometers in length, has nine stations. It will improve the traffic condition in the capital city's Fangshan District after it starts serving the public.
