The Shanghai Metro, as a crucial urban rail transit system in China, requires rigorous inspection work to ensure public safety. With digital transformation, adopting advanced technologies to enhance inspection efficiency has become essential.

User Background

The Chinese city of Shanghai and its surrounding metropolitan area are served by the Shanghai Metro urban rail transit system. It is a part of the Metro Community (CoMET). Shanghai became the third city in mainland China and the first in the south to open an urban rail transit system on May 28, 1993, when Shanghai Metro Line 1 went into official service.

Challenges

In the past, Shanghai Metro inspections relied on employees' personal mobile phones, which were difficult to handle in complex environments, prone to damage, and inefficient, leading to increased safety risks.

• Equipment vulnerability: Personal phones are not durable, easily damaged by drops or moisture in the metro environment, raising replacement costs.
• Operational challenges: Phone interfaces are not optimized for professional inspections, resulting in complex operations and high error rates, disrupting workflows.
• Inefficient data management: Inspection data is scattered, making it hard to consolidate and analyze, hindering fault prediction and decision-making.

• Reduced maintenance costs: The stability and durability of industrial-grade products minimize repair and replacement needs, saving resources.
• Enhanced inspection efficiency: Dedicated equipment streamlines inspection processes, making subway inspection​ faster and more accurate, boosting overall operational efficiency.
• Ensured safe operations: Standardized procedures and real-time data feedback guarantee train safety and reduce accident risks.

• Adoption of CRUISE2 5G mobile computers: Shanghai Metro utilizes CRUISE2 5G​ for instant messaging and equipment inspections, standardizing the cruise2 5g subway inspection application to enable fixed-point checks, fault reporting, and station inquiries.
• Integration of positioning functions: The equipment supports patrol check-in positioning, enhancing the accuracy and traceability of public transport inspection.
• Big data analysis and management: Using the AUTOID Pad Air-5G large-screen device, team leaders can review daily work reports, optimizing equipment fault reporting​ and resource allocation.
