China News Network, Beijing, April 2 (Reporter Du Yan) From the window of a subway train, you can see the degree of congestion of the front and rear carriages, and you can know in advance the route map of the upcoming transfer station ... On the 2nd, the reporter boarded in Beijing The smart train of Metro Line 6 saw its window turned into a screen, displaying the train driving information and the information of the station in front, and a display screen was added above the door to realize the "window screen" intersecting and efficient service for passengers.
Li Yujie, deputy director of the technology department of Beijing Metro Operation Co., Ltd., introduced that this is the first company in the United Nations of Beijing Metro Operation Co., Ltd. to master the core technology of the independent CBTC signal system-Traffic Control Technology Co., Ltd. One of the achievements of the "smart capital subway" scientific research project, the intelligent train passenger service system, is currently being tested on Beijing Metro Line 6.
He said that Beijing combined with artificial intelligence, big data, cloud computing, 5G, China Beidou satellite navigation system and other new-generation information technologies, and is committed to creating a digital, informatized, networked and intelligent set of new smart subway operation models, including There are four major application scenarios of intelligent customer service, intelligent operation, intelligent maintenance, and intelligent management. There are two important node projects, including intelligent trains and intelligent stations. "The smart customer service system we are seeing today is an important part of smart trains, which was launched in October 2019."

At the platform of Hujialou Station of Metro Line 6, the reporter saw the smart train slowly entering the station. The combination of the "waiting guidance screen" and the shielded door allows passengers to see in advance the operating position of the "smart train", the congestion of different cars, and the strong cold / Weak cold compartments, which make it easier for passengers to choose the right place to wait and reduce the queue time for passengers.
Entering the train compartment, the place where the train arrival information is usually displayed just above the door becomes a 4K high-definition screen. Here you can not only see the train driving information in Chinese and English, but also the passengers can clearly understand the screen content constantly changing. Information about the station toilets, escalators, and exit locations of the station.
It is worth mentioning that a 4K high-definition screen has been added above the two-carriage channels. The center of the screen displays the name of the next station in Chinese and English. At the same time, passengers can see which car they are in, which door will open, and whether the front and rear cars are congested.

If the rich and diverse information provided by these new media surprises passengers, then after the train starts, the train window turns into a 55-inch "magic mirror", which is "amazing".
After the train is started, a three-dimensional schematic diagram is displayed on the windows showing the route map of the entire network, allowing passengers to see the train “traveling” between high-rise buildings, and also let passengers know the current position of the train, the network map and the exit of the station in front Nearby commercial facilities.
These are all new services visible to passengers. Li Yujie said that in the compartment, there were "eyes" staring at the safety of passengers.
He introduced that by using in-car perception cameras, through image recognition and intelligent analysis technology, "smart trains" have realized the monitoring and alarming of passengers in the car who fainted and waved for help. At the same time, a driver is also installed in front of the driver to use the driver's facial features to infer the driving status. Once the driver is monitored for fatigue and distraction, the system will give voice prompts, which also adds intelligent security for passengers.

In addition, smart trains can also collect information such as the full load rate, temperature, humidity, and air in the car in real time, and upload them to the operational monitoring cloud platform along with other train operating data, providing a digital basis for improving comfort and operating management.
Li Yujie said that the platform also supports the expansion of "Clairvoyance", "Wind-ear ears" and "intelligent operation and maintenance" functions. During the train interval operation, through active sensing based on artificial intelligence, as long as there are dangerous obstacles and people in front, the system automatically alerts, Prompt speed reduction; after the train returns to the warehouse, connect the WIFI in the warehouse to upload operation and maintenance data, which provides strong support for equipment maintenance and fault prediction.
He said that compared with the traditional system, the intelligent train passenger service system represents the future development direction of the passenger service system. At present, the system has entered the operation trial stage, and the service functions will continue to be improved in the future. "We will strive to build and complete four application scenarios in the next 3 to 5 years to make services smarter, ride more efficient, and operate safer." (End)
