Method and device for detecting multiple places of structural deformation or displacement of object in real time

Abstract

The invention provides a method and device for detecting multiple places of structural deformation or displacement of an object in real time. The method includes steps that a ranging device and a reflection prism (which is required in specific conditions) are arranged in proper positions; reflection faces are arranged on each to-be-detected positions of a structure; the ranging device emits electromagnetic waves which propagate forward after passing through each reflection face in sequence and the electromagnetic waves passing through all the reflection faces are reflected to the ranging device or reflected to the reflection prism and then reflected to the ranging device after passing through all the reflection faces along the original path, wherein the ranging device measures the distance travelled by the electromagnetic waves and whether the structure deforms or not is judged according to the distance measured by the ranging device. the method provided by the invention can measure multiple places of structural deformation of the object at a low cost, with high precision and nearly in real time. 本发明提供一种实时检测物体的多处变形的方法与装置，该方法包括以下步骤：在适当位置分别设置测距装置和反射棱镜(只是在某些情形下需要使用反射棱镜)；在所述结构上的每一需检测的位置上设置反射面；从所述测距装置发出电磁波；所述电磁波依序经过所述每一反射面而向前传播；经过所有所述反射面反射的电磁波被反射至测距装置，或反射到所述反射棱镜并且沿着原路经过所有反射面反射至测距装置；其中所述测距装置测量所述电磁波经过的距离，通过所述测距装置测得的距离判断所述结构是否发生变形。本发明提供的实时检测物体的多处结构变形的方法能够低成本、高精度、近实时地测量物体的多点结构变形。
