The Challenge
• Shanghai is an international metropolis. With integrated development of urban transport, rail systems are central to intercity integration and urban ecosystem development.• Shanghai Metro carries nearly 10 million passengers each day, serving 52% of residents. Managing the rail network is becoming increasingly difficult thanks to the expansion of metro lines and stations, an increasingly complex system, and the large volume of passenger flow.
• There is an urgent need to guarantee the safe, reliable and efficient operation of Shanghai Metro while providing passengers with a comfortable and convenient experience.
• Electrical safety and stability in the stations. There are a lot of electrical facilities that consume a large amount of power inside the limited space of the stations. Uninterrupted and stable power supply is necessary to guarantee the normal operation of various systems.
• Environment and safety in the stations. As more passengers use the system, it is critical to control the temperature, humidity, ventilation and lighting for comfortable station environments.
• Emergencies and disasters impose higher requirements on the fault tolerance, reliability and comprehensive response of the systems.
• Data collection and information management. The complex, isolated systems and the intricate operations of equipment make it a daunting task to collect, monitor and analyze data between connected systems.
• Operation and maintenance cost. Manpower costs make up a large portion of annual operational expenses. The complex operations of managing equipment raise maintenance costs year by year.
