Description

The present invention relates to a crack sensing and monitoring device, and more particularly to a crack sensing and monitoring device capable of sensing cracks in multiple stages.

In general, buildings such as bridges and buildings often suffer significant damage from accidents caused by cracks and collapses in foundations and rocks. Cracks can be caused by external shocks such as earthquakes or land subsidence, or internal problems such as aging or shoddy construction. Cracks start out as tiny streaks, but they grow larger and larger, and if they exceed a certain limit, they can cause buildings and rocks to collapse.

To detect such cracks, there are two ways to detect them: visually or by using sensors to identify the beginning of the first crack. However, this method has the problem that it is possible to check only when a crack first occurs, and that it is difficult to check the progress of an existing crack at each stage.

Regarding this, Republic of Korea registered patent No. 10-1684375 (registered on December 02, 2016) has been devised.
