Abstract: The roof of Xiong’an Railway Station is elliptical in plan, with a long axis of 450m and a short axis of 355.5m, and its main structure is a large-span space steel structural system. In order to investigate the actual force state and deformation of this roof structure and improve the safety of the structure during operation, a wireless health monitoring system was designed and developed for the steel structure of Xiong’an Railway Station. The sensor selection and measurement point deployment plan were introduced in detail, and an all-round structural health monitoring sensing layer based on strain, displacement, and temperature sensors was established. A tree network topology transmission layer was built with sensor nodes, communication routing nodes and base stations for data information interaction. And a structural monitoring cloud platform analysis layer with integrated data query, equipment management, alarm maintenance and other functions was developed. The analysis results of the field-measured data verify the effectiveness of this wireless health monitoring system. The application of this wireless health monitoring system realizes the real-time mastering of the status of the structure, which contributes to guaranteeing the safe operation and maintenance of the Xiong’an Railway Station.
