The invention discloses a remote monitoring early warning system for deep foundation pit support structure deformation. The system is characterized in that the method that theoretical research and numerical simulation are combined is adopted for researching the structural deformation conditions of a deep foundation pit support pile, a steel support and the like in the construction process. Based on the application technology of the Internet of Things, the real-time monitoring early warning technology is researched. According to the requirements and the characteristics of the remote monitoring early warning equipment system for deep foundation pit support structure deformation, an Internet of Things frame of an M2M model composed of a data acquisition part, a communication liaison part, kernel processing space and a data terminal is constructed. The construction process mainly includes the steps of construction of the Internet of Things frame for monitoring deep foundation pit support structure deformation, construction of a physical structure of the monitoring system and construction of a system software system. The remote monitoring early warning system for deep foundation pit support structure deformation can accurately remove potential safety hazards for a subway engineering management and construction department to master the deep foundation pit support structure deformation condition in real time in the construction process and provide information technology support and guarantees for effectively preventing foundation pit construction accidents.
