Remember this map of the London Underground?
In 1933, cartographer Harry Beck replaced the sinuous lines on the map with staggered straight lines on the London Underground map, creating the prototype of the modern Underground map, which has become one of the classic cases in the visualization industry.
Nowadays, with the wave of digitalization and intelligence, a subway floor plan can only meet the daily management needs of tourists and administrators, while problems such as complex and incompatible station data, difficult coordination and linkage of various positions, and large passenger flow are like a mountain pressing on the business chain of the subway operation and management department, so that the subway operation has the risk of interruption at any time.

Click on the overall overview interface "Enter Station" to enter the station operation and management interface, and the realistic style of the station 3D modeling comes into view, based on the dynamic symbiosis of digital twin technology and real station space, which is subdivided into three scenarios: station operation and maintenance, passenger flow and heating, and safety and environmental monitoring.
(1) Station operation and maintenance
Check the facilities and equipment such as turnstiles, escalators, and trains in the station and the dispatching center, and click any icon to view the real scene and details of the facilities and equipment. When an accident occurs, the platform automatically alarms and displays the jurisdiction unit and accident details, improving the incident response speed. Real-time monitoring of station duty and train operation, support statistical analysis of station security inspection events and incident occurrences, increase security personnel and police force in a targeted manner, and strengthen the maintenance of security equipment; support early warning analysis of train systems, promote train maintenance mode from planned repair and fault repair to state repair and predictive repair, and reduce the occurrence of subway operation accidents. The IoT senses the number of devices and energy consumption in the station, and can take predictive repair and fault repair measures based on the equipment alarm trend and real-time monitoring to improve the operation efficiency of the subway station.
(2) Passenger flow heat
Construct a heat map of passenger flow zones in the station, use red, orange, and green to represent the passenger flow density, pop-up windows in the partition, personnel density and other data, and automatically warn when the crowd density exceeds the set safety value. Real-time monitoring of passenger flow, statistics of passenger flow within a certain period of time, passenger flow at each entrance, transfer and other data, is conducive to the administrator according to the distribution of passenger flow to reasonably arrange the opening and closing of platforms and entrances and exits, optimize the station layout and transfer channel design, reasonably adjust the train frequency and operation interval, and improve the efficiency of subway transportation and passenger travel experience.
(3) Safety and environmental monitoring
