IPSS of Beijing Metro Line 6

Train - Intelligent Passenger Service System (T-IPSS) has been put into trial operation in Beijing Subway Line 6, and the functions will be improved continuously in future.

In the passenger compartment, T-IPSS can provide passengers with rich and diversified information services through new media. By means of new 4K HD screen arranged above door and aisle, passengers can know the information from different positions such as next station, toilets of next station, elevator, transfer route, exits and congestion of front/rear compartments. In addition, the train window becomes a 55” “magic mirror” to display the current position of train, line map and 3D diagram of next station after the train starts moving.    

Before the “intelligent train” comes, the operation position and the congestion and cold state of compartment can also be displayed so that passengers can choose suitable waiting positions. In the future, operation information such as “overtaking trains” will also be displayed. Besides, “eyes” protecting passenger safety are arranged in the compartment, that is, perceptual camera, advanced image recognition and intelligent analysis technology are used for detecting the passengers who are fainting or need help. Sensing equipment is also installed in front of driver to judge the driving state according to the facial features, that is, once fatigue or distraction is detected, the system will send voice prompt, so as to guarantee the passenger safety actively and intelligently.    

The train can collect interior information such as full load rate, temperature, humidity and air and upload it to operation monitoring cloud platform together with other operation data, thereby providing a digital basis for comfort improvement and operation management. It can also realize “networking”, i.e., the train-level information transmission through wireless Ad-Hoc Network. The system is provided with a bad information filtering “firewall” to avoid illegal texts and videos. An integrated platform is also established to summarize information and control logics centrally. The platform also supports functions such as “clairvoyant”, “clairaudience” and “intelligent operation and maintenance”, so as to send alarm and prompt to deceleration    


automatically as long as dangerous obstacles and personnel in the front are detected by TIDS during operation; after the train returns depot, it can be connected with WIFI to upload operation and maintenance data, so as to support equipment maintenance and fault prediction.
