On June 28, at the "2024 Digital Urban Rail Innovation Forum" held in the Shanghai Science Hall, CASCO released the "Xihe" digital urban rail solution. The solution focuses on improving operational safety and resilience, and based on the self-developed open rail transit digital base and scalable information control professional model, it builds two platforms of intelligent operation control and intelligent operation and maintenance, and integrates a series of intelligent application products to help the digital and intelligent transformation and upgrading of the industry.
Xihe, inspired by the Chinese mythology of the mother of the sun who travels to the sun and controls the time sequence, carries a beautiful vision for the future development of digital urban rail, and creates a new urban rail ecology with digital intelligence integration and harmonious symbiosis with safe and efficient professional algorithms and resilient and inclusive open services.
The intelligent "platform + product" combination is flexible and configurable
Based on the open rail transit digital base, the "Xihe" digital urban rail solution is an iterative upgrade of CASCO's "fully automatic operation 2.0 system for smart subway", which builds two core platforms of intelligent operation control and intelligent operation and maintenance, forming a "smart brain" and "health steward" to protect the operation of trains, and helps enterprises reduce costs and increase efficiency through the deep integration of advanced technologies such as multi-source ubiquitous perception, trusted artificial intelligence, big data, and the Internet of Things.
Intelligent operation control is an operation control and management platform with driving command as the core, multi-discipline integrated integration, and intelligent collaborative linkage for operation scheduling, station affairs, drivers, and maintenance personnel.
Intelligent O&M is a comprehensive integrated rail transit O&M platform for rail transit maintenance scenarios, integrating technologies such as the Internet of Things, PHM health prediction, and artificial intelligence to realize multi-professional equipment, health prediction, fault diagnosis, production control, emergency disposal, and maintenance decision-making.
Based on the two platforms, CASCO has also successfully cultivated a series of star products, including intelligent train control, intelligent scheduling, intelligent stations, intelligent sections, as well as intelligent terminals such as integrated platform doors and train autonomous perception system TAPS.

From a single product to a comprehensive service solution, "Xihe" integrates digital and intelligent innovative applications in the urban rail field, and can flexibly configure solutions according to the needs of application scenarios, even in the face of some challenging industry problems.
"Xihe" can effectively improve the holographic environment perception ability of trains under complex working conditions, and with the help of lidar and machine vision, it can realize obstacle identification and braking protection to ensure driving safety.
In the case of rain and snow in bad weather, through real-time evaluation of the adhesion state of the vehicle's wheels and rails, the advanced intelligent algorithm is used to comprehensively and accurately identify the slippage risk areas in the line, and the adaptive adjustment control strategy is adopted to reduce the probability of train slippage and ensure safe and reliable operation.
When the signaling system fails, the ubiquitous perception technology and autonomous safety protection system can be used to ensure that the train runs to the platform in a fully automatic mode, avoiding the vehicle from staying in the track area for a long time, ensuring the safe boarding and landing of passengers on the platform, and improving the resilience of the operation.
The "Xihe" digital urban rail solution can provide passengers with excellent travel services with optimal scheduling and control, and maintain the optimal working condition of the system with lower operation and maintenance costs. Under the condition of unchanged resources, "Xihe" can achieve about 30% increase in transportation capacity, save about 30% of fault and emergency response time, change "people looking for data" to "data looking for people", optimize the human-computer interaction relationship, post setting and business integration is closer, greatly reduce labor costs and management costs, and provide passengers with more efficient, safer and more reliable travel services.
Through multi-discipline integration and multi-post collaboration, the "Xihe" digital urban rail solution realizes the innovation and optimal allocation of production factors in all aspects of train operation and maintenance, and has the characteristics of innovation, high technology, high safety, high efficiency and sustainability, and is becoming a representative of new quality productivity in the field of urban rail signaling.
Self-developed digital base empowers industry applications
CASCO has customized and developed a large open rail transit digital base for "Xihe", which has the ability of multi-discipline global data access and governance of "people, machines, things, law and environment", which can carry out real-time trusted governance of data such as human error, system operation and equipment status, ensure the timeliness, integrity and security of data, and provide data support for intelligent operation.
In addition, CASCO also released the "Orbital Starry Sky" model at this forum, which can be used for professional knowledge sharing and operation log analysis in the field of urban rail, and further expand the application of artificial intelligence in the field of rail transit.
Create an industry community to promote collaborative innovation
Building a digital urban rail is a long-term battle, which requires the entire industry to pour wisdom and strength into it. Taking this forum as an opportunity, the first "Digital Urban Rail Innovation Community" in China was announced, bringing together more than 30 member units of the entire upstream and downstream industry chain of production, learning, research and use, aiming to actively integrate the superior resources of all parties and jointly explore the way of high-quality and sustainable development of digital urban rail.
