Abstract: In order to study the strain of the bursting panels during dust explosion, realize full intelligent control and acquisition, a strain research method of the bursting panels based on LabVIEW is designed. The method uses Wheatstone bridge to convert the stress change of the strain gauge arranged on the bursting panels into electrical signal. At the same time, the work of the infrared camera, high-speed camera and pressure sensor is synchronized through the LabVIEW software, data acquisition card, etc., so as to realize the comparative analysis of the explosion pressure in the tank, the strain value of the blasting panels and the image of the blasting panels at that time during the explosion. The experimental results show that the method meets the experimental requirements of synchronization, diversity, accuracy, etc. It has the characteristics of high degree of modularization, strong real-time performance, and good scalability, which is helpful to improve the structure of the bursting panels.

Key words: bursting panels, strain gauge, synchronous acquisition
