Problems solved by technology

In view of the unpredictability of the original defects of materials, design and construction deviations, use and environmental degradation, the time and location of structural damage are difficult to predict, and the existing monitoring methods with limited points are difficult to capture the initial damage caused by structural damage, even if the monitoring points show Without the abnormal test data, it is difficult to clearly point out the specific part of the injury
The existing fracture monitoring technology is difficult to achieve economical, practical, long-term, online, and accurate monitoring of the occurrence and development of fractures

Abstract

The present invention discloses a structural crack bionic monitoring system and a monitoring method thereof. The structural crack bionic monitoring system comprises a plurality of smart wires I on the structure to be monitored and a monitoring unit composed of a plurality of smart wires II. The smart wires I and II which are insulated from one another are crossly provided on the structure to be monitored to compose a smart neural network of plane coordinate system on the structure to be monitored. The invention can accurately confirm the generated position, shape, length, time and expanding state of the slit according to the perception mechanism of the animal skin to the wound through the analysis of the signal processing device to the signal that is transmitted and received by the smart wire I and II. The engineering structure can be actualized with continous and omnibearing damage state monitoring. The bionic monitoring sensing system has the advantages of convenient and simple operation, high efficiency, low cost and reliable result.

Description

technical field [0001] The invention relates to an online monitoring system and a monitoring method thereof, in particular to a structural crack bionic monitoring system and a monitoring method thereof. Background technique [0002] The disease and final failure of concrete structures start with the occurrence and development of cracks, and the condition of cracks in key areas becomes the main basis for visually judging the health of concrete structures. For this reason, experts and scholars from all over the world have done a lot of exploration and research on the monitoring methods for the occurrence and development of cracks in key areas during the use of concrete structures. The existing sensing technologies for safety monitoring of engineering structures include: a. Implant or paste functional optical fiber on the structure, and judge the deformation or fracture of the structure in real time by measuring the deformation or fracture of the optical fiber; b. Elastic stra...
