Test method for detonation velocity of nonel with defect

Abstract

The invention discloses a test method for detonation velocity of a nonel with a defect. The test method is a non-contact test method characterized in that digital images are shot by utilizing a high-speed camera, the images are subject to digital processing by a CAD (Computer Aided Design) software of a computer so as to realize detonation velocity test of the nonel. According to the test method, the measured detonation velocity is closer to the instantaneous velocity of a measure point; the normal start of the high-speed camera in detonating moment of the nonel can be guaranteed, and the required whole process can be shot; the calculated amount is reduced, and the difficulty of data processing is lowered; the AUTO CAD software is introduced in data processing, and the distance can be more conveniently and accurately measured by utilizing a proportional scale function, a building block function, and a zoom in and out function in the CAD.

Description

technical field [0001] The invention uses a high-speed camera to take digital pictures, and performs digital processing through a computer to realize the detonation velocity test method of a detonator, belonging to the technical field of non-contact testing. Background technique [0002] Because the nonel detonation system has many advantages such as good antistatic performance, simple and flexible network connection, good high and low temperature resistance, strong moisture and water resistance, and stable performance, it can be matched with non-electric millisecond delay detonators to achieve unlimited blasting Network one-time ignition and differential blasting can achieve high delay accuracy, meet the requirements of large-scale blasting, and greatly improve the safety and operation efficiency of engineering blasting. Therefore, the nonel is widely used in the field of engineering blasting. With the enhancement of my country's economic strength and the progress of scienc...

Problems solved by technology

[0003] During the production, assembly, transportation, and storage of the detonator, the powder on the inner wall of the detonator often falls off or breaks due to bumps, vibrations, etc.; Objects piercing the detonator, etc., causing the detonation velocity to decrease or even reject

Moreover, the nonel detonation system cannot use instruments to check the network quality before the explosion like the electric explosion network. It can only judge whether the connection is good or bad by experience and intuitive feeling, and the reliability cannot be guaranteed. Detonation reliability is the key factor to determine whether the nonel detonation system is reliable to detonate
