Deformation measurement and early warning system and method integrating satellite positioning and accelerometer

Abstract

The invention discloses a deformation measurement and early warning system and method integrating satellite positioning and an accelerometer. The system comprises an accelerometer module, a GPS (Global Positioning System) receiver module, a control panel module, an upper computer and a remote terminal. The accelerometer module is used for outputting acceleration information of a station and the GPS receiver module is used for outputting the measurement information of the station, a satellite ephemeris and a satellite health status; the control panel is used for supplying power to a GPS_OEM (Original Equipment Manufacture) board and the accelerometer module and is used for carrying out time synchronization on digital signals output by the accelerometer module and the GPS receiver module; the upper computer is used for controlling a work status of the system and receiving the synchronized digital signals output by the control panel, carrying out data fusion through Kalman filtering calculation, carrying out early warning by utilizing a cumulative sum algorithm, displaying relevant information in real time and transmitting; and the remote terminal module is used for receiving data and warning information, which are transmitted by the upper computer. The deformation measurement and early warning system and method provided by the invention can be used for monitoring and early warning of various dynamic deformations of mining area shafts, high-rise buildings and the like, and can ensure the completeness of the early warning.

Description

technical field [0001] The invention belongs to an engineering deformation monitoring and early warning system and method, in particular to a satellite positioning and accelerometer tightly integrated deformation measurement and early warning system and method. Background technique [0002] The Global Positioning System (Global Positioning System-GPS) is a new generation of space satellite navigation and positioning system jointly developed by the US Army, Navy and Air Force in the 1970s. The GPS system performs positioning by receiving wireless signals sent by 24 navigation satellites distributed in the sky. Global, omnipotent (land, ocean, aviation and aerospace), all-weather and other advantages, it can provide users with accurate navigation positioning, timing and speed measurement information, and users can realize all-weather, continuous and real-time three-dimensional navigation and positioning on a global scale and tachometer. In addition, using this system, use...
