Test system and test method for testing electric detonator electromagnetic radiation sensitivity

Abstract

The invention relates to an experimental system and method for measuring the electromagnetic radiation sensitivity of an electric detonator. The system includes: electromagnetic radiation signal monitor, electromagnetic radiation generator, signal enhancement, signal weakening, electric detonator, time measuring instrument. The test method is as follows: Step 1: Selection and placement of the electric detonator, select the type of electric detonator required for the experiment and place it in the explosion-proof safety box; Step 2: Debug the time measuring instrument, use a voice-activated timer, and stop the timing when the electric detonator detonates immediately; Step 3: Conduct an experiment, turn on the electromagnetic radiation generator to a certain fixed electromagnetic radiation intensity value, first select the signal weakening line, gradually weaken the electromagnetic radiation signal, and then act on the electric detonator in the explosion-proof safety box to observe the detonation situation; if not Initiate the explosion, then select the signal enhancement line, gradually enhance the electromagnetic radiation signal, and then act on the electric detonator in the explosion-proof safety box, observe the detonation situation, and record the time and other data until the electric detonator detonates.

Description

technical field [0001] The invention relates to the field of blasting equipment testing, in particular to an experimental system for measuring the electromagnetic radiation sensitivity of an electric detonator. Background technique [0002] Electromagnetic wave radiation, also known as electromagnetic radiation, is the energy and momentum transmitted in the form of waves in space by the electric field and magnetic field that oscillate in phase and are perpendicular to each other, and its propagation direction is perpendicular to the plane formed by the electric field and magnetic field. The energy derived from electromagnetic radiation, Depends on the frequency: the higher the frequency, the greater the energy. During the experiment or engineering blasting construction related to electric detonators, the electromagnetic wave radiation emitted by communication or electronic equipment such as mobile phones is likely to detonate the electric detonators, which has great potentia...
