Abstract: Through the application of new generation information technology such as Internet of Things， cloud computing and big data， the smart park realizes the automation and intelligence of park management or services， and promotes the high-quality development of the park. This paper proposes a smart park management platform architecture for multi-source data， constructs a smart park data management gateway. The gateway integrates and extends the park equipment and facilities management system， integrates the existing informatization achievements of park management and services， and builds a new park real-time state awareness system based on the Internet of Things， which solves the problems of “information islands” and data interaction of multi systems， multi platforms and multi criteria in the park management. Through GIS map panoramic presentation and business function linkage， we realize the centralized display， integrated management and unified dispatching of the park’s real estate， equipment and facilities， which provides real-time， comprehensive and accurate technical support for the park’s operation monitoring and management. The architecture has been realized in Shanghai free trade zone and it achieves good economic and social benefits.
