Embodiment Construction

[0022] The present invention is based on a piezoelectric sensor structural health assessment software platform implementation method, such as figure 1 As shown, the specific steps are as follows:

[0023] Step 1, build the structural health assessment software platform based on piezoelectric sensor, 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, Using the MFC programming environment, create a dialog project;

[0024] Step 2, the software data interface, transmits the processed sensor position information, center frequency, signal amplitude, and magnification data to the software platform for further data processing and display, and the results of data processing are stored in the database . The software platform acts as the server, and connects with the customer service after the server is turned on. If the connection fails, the s...

Abstract

The invention provides a piezoelectric sensor-based structure health evaluation software platform realization method. The method includes the following steps: first, software platform building based on a Microsoft C / C++ compiler, namely VC (MicroSoft Visual C / C++), and a Microsoft foundation class library, namely MFC (Microsoft Foundation Classes); second, realization of software data interfaces;third, software realization of algorithms; and fourth, realization of software functions. Through the above steps, the piezoelectric sensor-based structure health evaluation software platform realization method is completed in the invention, and can evaluate a health condition of a structure; and in addition, a software platform encapsulates each function into a module, each module can independently run, program function expansibility, portability and secondary development performance are good, and practical engineering application is facilitated.

Description

technical field [0001] The invention provides a structural health assessment software platform implementation method based on piezoelectric sensors, including software data interface, software implementation of algorithms, and software implementation of functions, which can complete image display of sensor placement positions, damage monitoring and display, damage The quantitative monitoring and display of position and size, the evaluation result and display of probabilistic remaining life, and the early warning function of structural danger belong to the technical field of structural health monitoring. Background technique [0002] Piezoelectric sensors are sensors made using the piezoelectric effect produced by certain dielectrics under force. The so-called piezoelectric effect means that when some dielectrics are deformed (including bending and stretching deformation) by an external force in a certain direction, A phenomenon in which charges are generated on the surface d...
