With the deepening of digital transformation, the smart operation and maintenance platform has become an essential to ensure the healthy operation of integrated transportation hubs and improve the operation and maintenance efficiency and effect. Based on the digital and intelligent operation and maintenance goals of Hongqiao Transportation Hub, the Internet of Things technology, digital twin technology, artificial intelligence technology and big data technology are comprehensively used. The integrated smart operation and maintenance platform for facilities and equipment based on the digital twin hub is proposed to realize five functions of operation management, parking management, smart maintenance, energy consumption management and asset management. The monitoring and diagnostic capabilities of equipment, and the smart management and control capabilities of facilities and equipment capabilities are upgraded, and the response speed and business collaboration level of operation and maintenance are improved, which provide the technical guidance for the digital transformation of subsequent operation and maintenance of the transportation hub.
