Problems solved by technology

[0004] Existing structural health monitoring software platforms cannot use fiber optic sensors and smart coating sensors to monitor the health of structures at the same time. Most of them use a single sensor for health monitoring, and the program function scalability, portability and secondary development are relatively low. Difference

Embodiment Construction

[0040] The present invention is a structure monitoring software platform based on optical fiber and intelligent coating, such as figure 1 As shown, the specific steps are as follows:

[0041] Step 1, at first determine programming language, the present invention uses Microsoft C / C++ compiler version 6.0 (being VC++6.0) to carry out the writing of program, build programming environment on this basis, utilize MFC programming environment, set up dialog box project;

[0042] Step 2, the software platform acts as the server side, creates a Socket after opening the server, and connects with the customer service end. If the connection fails, the server is restarted. If the connection is successful, the processed optical fiber sensor and smart coating sensor data are received; The process of opening the server side of the software platform of the TCP / IP protocol, connecting the client side, and transmitting data between each other is as follows: figure 2 shown;

[0043] Step 3, dis...

Abstract

The invention provides a realization method based on a fiber and an intelligent coating layer structure monitoring software platform. The method comprises steps that 1, the software platform is constructed; 2, processed fiber and intelligent coating layer sensor data is transmitted to the software platform; 3, the position of the fiber distributed in an actual structure and the intelligent coatinglayer sensor is displayed through three-dimensional images; 4, a stress strain value of each fiber grating point is monitored; 5, crack sizes are monitored in real time, and observation of crack change is facilitated; 6, a crack fault development trend and the probability residual life evaluation result are displayed on the software platform; and 7, danger early warning of the monitored structureis carried out. The method is advantaged in that the structure monitoring software platform based on the fiber and the intelligent coating layer is realized, structure crack and strain monitoring functions are realized, moreover, independent operation among the modules is carried out, program function expansibility, portability and secondary development property are good, and the method is suitable for actual engineering applications.

Description

technical field [0001] The invention provides a realization method based on an optical fiber and intelligent coating structure monitoring software platform, which relates to a method for receiving, storing, and real-time displaying of optical fiber and intelligent coating sensor signals, and realizing three-dimensional images and cracks of sensor placement positions. The display of the size and the function of early warning of structural danger belong to the technical field of structural health monitoring. Background technique [0002] With the emphasis on the reliability of products and equipment in various fields, the development of structural health monitoring is extremely rapid. In the field of structural health monitoring, an optical fiber sensor (a fiber made of glass or plastic, can be used as a light transmission tool, the basic working principle is to send the optical signal from the light source to the modulator through the optical fiber, so that the measured param...
