Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0038] The present invention establishes a database by artificially simulating the parametric stresses when the actual building rigid parts are deformed when they are affected by external factors, so as to provide accurate judgments for subsequent monitoring of the actual building rigid parts.
[0039] Since the monitoring methods of building rigid parts are the same, this method can be used for building rigid parts of different parts. In the specific use, take the stress monitoring of building rigid parts of houses as an example to explain in detail.

The invention discloses a strain safety monitoring method for a building rigid part. The method comprises the following steps: arranging a detection fiber in a building rigid part of a to-be-built object in advance or opening a micro groove in a building rigid part of a built object body to arranging a detection fiber, carrying out wall repairing to realize close contact of the detection fiber with the building rigid part, and arranging a signal detection unit at the end portion of the detection fiber. Artificial simulation is carried out on actual vibration, inclination or collapse of the detection fiber; and then a data model is established. According to the invention, typical vibration data of the building rigid parts under different levels of strong wind and earthquakes are collected and analyzed in real time under actual field working conditions based on the coherent-Rayleigh-scattering-principle-based novel distributed optical fiber vibration sensing technology; characteristic parameters endangering house safety events are extracted; an analysis model is established; and the monitoring and early warning of dangerous events of the object building rigid parts are realized efficiently in real time by combining a mode recognition algorithm.
Description
technical field [0001] The invention relates to the technical field of building safety monitoring, in particular to a strain safety monitoring method for building rigid parts. Background technique [0002] Architectural rigid parts are ubiquitous in real life. Basically, any object with a shape has a structure with a stable shape of its holder, and the components that play a key role in the structure are architectural rigid parts, so architectural rigid parts The quality and state of the object determine the stability of the shape of the object. [0003] Ensuring the stability of the rigid structure includes the object itself and the state of the object, such as the tower crane, bridge erecting machine and bridge column itself in common construction in daily life. Due to their height, size and weight, how to ensure their stable standing during use The state of the foundation is a problem that needs to be solved, so how to ensure the stability of the rigid structure of the f...
