Apparatus for measuring displacement of public works and building structures

摘要

Displacement measuring device of the civil and building structures according to the present invention, the light emitting device is installed on a predetermined portion of the portion subjected to the load of the civil and building structures of the displacement measurement object to emit light; An optical detector installed at a predetermined portion of the structure at a point spaced apart from the light emitting device by a predetermined distance and detecting light emitted from the light emitting device; A signal converter which converts the optical signal detected by the optical detector into an electrical signal and converts the converted electrical signal (analog signal) back into digital data; A recorder for recording and storing the digital data converted by the signal converter in a memory; And a main control unit for measuring the displacement of the structure by comparing and analyzing the data recorded and stored in the memory by the recorder with preset reference data.;According to the present invention, since the light emitting device and the photodetector are directly installed at the displacement generating portion of the structure to be measured, the displacement is continuously detected in real time, and the displacement is measured by comparing / analyzing the detected value with the reference value. Compared to the conventional measuring method, it is practical and accurate to measure, and each structure such as road bridge can be easily measured without time constraints or usage control, and can be measured by only one manager. Very low burden
