Abstract:A deformation monitoring and early warning system based on a micro-services architecture is proposed, which is aimed to solve the difficulties in the integrated application of multi-source sensors in the monitoring of urban infrastructure structural deformation. Through the design of the micro-service architecture, the full-process functionalities including data acquisition, transmission, processing, storage, visualization, analysis and early warning are achieved, which successfully integrate nine types of sensor devices. The reliability and stability of the system have been thoroughly validated in the practical engineering applications, which can effectively monitor the structural deformation of urban infrastructure and promptly issue early warning information to provide the powerful support for the safety management of the city. Furthermore, the specific solutions are given to key issues such as physical architecture design, real-time communication, point map rendering, early warning engine implementation, and the implementation of both web and mobile platforms.
