Blast vibration prediction system based on VB and Matlab

Abstract

The invention provides a blast vibration prediction system based on a VB and a Matlab, and belongs to the technical field of civil engineering. According to the prediction system, comprehensive application of the VB and the Matlab is achieved through an ActiveX automation technique. The prediction system is divided into a traditional prediction method base and an emerging prediction method base. In traditional prediction methods, programs are generally written with a VB language directly, and a result is displayed on a VB interface; in the emerging prediction methods, the programs are written in an M file in a Matlab environment, an item of a main interface is clicked to enter some prediction method interface, the VB calls a Matlab program for computation, and then a prediction result is obtained and displayed on a window interface of the VB. In actual engineering, the prediction system is convenient to use, easy to operate, high in prediction precision and friendly in human-computer interaction interface.

Description

Technical field [0001] The invention relates to the technical field of civil engineering, in particular to a blasting vibration prediction system based on VB and Matlab. Background technique [0002] With the rapid development of my country's economy and the increase in infrastructure investment, blasting technology as an effective economic method has been widely used in many fields such as transportation, mining, water conservancy, and urban construction. However, while engineering blasting greatly promotes construction efficiency and reduces labor intensity, it also triggers a series of negative effects, such as blasting vibration, air shock waves, noise, toxic gases, flying rocks, etc., especially the impact of blasting vibration on the surrounding environment and buildings. It has a major destructive effect, and the problem of blasting vibration effects has received widespread attention and attention. How to predict and reduce the vibration effect of blasting while completin...

Problems solved by technology

In the process of program development, it is hoped that the development cycle is short, and most of them choose to use Visual Basic as the development tool. However, when the application program encounters complex mathematical operations, such as matrix calculations that require a large amount of calculations and real-time intuitive graphics for analysis results When displaying in a computerized manner, the workload of program design using VB is large, and the requirements for program designers are high, and the difficulty is also increased a lot.

On the other hand, although Matlab has many unique advantages, the Matlab program cannot be run out of its environment, which is inconvenient for developing commercial software; the Matlab program can be directly seen the source code of the program, which is not conducive to the confidentiality of algorithms and data; Realize port operation and real-time control
