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 due 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 the 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 analyse 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.
