Embodiment Construction

[0036] The present invention is based on the implementation method of the optical fiber Bragg grating sensor structure health monitoring software platform, such as figure 1 As shown, the specific steps are as follows:

[0037] 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;

[0038] Step 2: The software platform acts as the server, 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 center wavelength information about the measured grid point is received. . The process of opening the server side of the software platform of the TCP / IP protocol, connecting the client side of the hardware platform, and transmitting data between...

Abstract

A structure health monitoring software platform realization method based on a fiber Bragg grating sensor comprises the following steps: 1, building a software platform based on a C / C++ compiler and a Microsoft foundation class; 2, transmitting central wavelength position information to a software system through a network communication protocol; 3, displaying the position of the fiber Bragg grating sensor in a three-dimensional image mode; 4, monitoring stress strain values calculated through fiber grating points to display changing of observation data in real time; 5, monitoring the sizes of cracks to facilitate observing the changing condition of the cracks; 6, calculating and obtaining the development trend of the crack faults and the assessment of the probability residual life, and performing displaying on the software system; and 7, performing danger early warning of the monitored structure. The structure health monitoring software platform realization method based on the fiber sensor realizes a fiber Bragg grating sensor structure health monitoring software platform, has functions of monitoring structure cracks and strains, and is good in program function expansibility, transportability and secondary development so as to facilitate engineering application.

Description

technical field [0001] The invention provides a method for realizing a software platform for structural health monitoring based on an optical fiber sensor, which is a method for realizing a software platform for structural health monitoring based on an optical fiber Bragg grating sensor. Storage, real-time display, and realization of the three-dimensional image of the sensor placement position, the display of the size of the crack, and the early warning of structural dangers, etc., 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, fiber Bragg grating sensors have been widely used due to their advantages of small mass, high sensitivity, and corrosion resistance. Fiber Bragg grating sensors are mostly used to monitor structural cracks and re...
