technical field [0001] The invention relates to a building deformation monitoring device and a monitoring method, in particular to a large building deformation monitoring device for real-time online deformation monitoring of a large building and a monitoring method using the same. Background technique [0002] When performing performance testing on large buildings such as houses, bridges, and dams, it is usually necessary to measure the shape changes of their important parts; these buildings will also be deformed due to changes in natural conditions and loads exceeding the limit during use, and the deformation will exceed a certain limit. cause havoc. Therefore, the deformation monitoring of large buildings is very important to ensure its safe use. At present, the monitoring of deformation is mainly the method of using displacement sensor and the indirect measurement method of calculating deformation by measuring strain.
