Title: Smart Sync System and IoT (Internet of Things) for Near Real-Time Monitoring of Burj Khalifa/迪拜哈里发塔的智能同步和物联网化近实时监控
Abstract: The design of high-rise developments worldwide is governed by a unique set of design limit states that encompass not only survivability and serviceability but also habitability, which all must be satisfied in increasingly complex wind environments. In fact, even though the performance of tall buildings affects the safety and comfort of a large number of people, their design continues to be based on analytical and scaled models that have not been widely validated in full-scale.
This study introduces a unique prototype system for structural health monitoring (SHM), SmartSync, which uses the building’s existing Internet backbone as a system of virtual instrumentation cables to permit modular and largely plug-and-play deployments. Within this framework, data streams from distributed heterogeneous sensors are pushed through network interfaces in real time and seamlessly synchronized and aggregated by a centralized server, which performs basic data acquisition, event triggering, and database management while also providing an interface for data visualization and analysis that can be securely accessed. The system enables a scalable approach to monitoring tall and complex structures that can readily interface a variety of sensors and data formats (analog and digital) and can even accommodate variable sampling rates. This study overviews the introduction of a SmartSync system (an internet of Things, IoT, concept within SHM), its installation/operation in the world’s tallest building, Burj Khalifa, and proof-of-the -concept in triggering under dual excitations (wind and earthquake). It also highlights modules for an automated system identification with quality assurance checks as well as novel response parameterization modules, on the fly analysis modules including a near real-time System identification module that provides in real time estimates of structural properties like frequency and damping.
