The Development of a Realtime Remote Monitoring System for the Subsidence of Building

A system, which is real-time, remote, automatic for monitoring the subsidence of building, is introduced. Hydrostatic leveling, displacement sense by electromagnetism, computer technology are integrated into the system. The system can realize real-time, continuous acquisition and management of the measured data, and when the quantity and speed of the subsidence exceed the certain warning value,the system can realize automatic early-warning. Compared with geometrical leveling, the system has advantages of high accuracy, real time, continuous, unattended, remote, wireless for monitoring and early-warning.
