Detection control method for wireless detonator detonation network

Abstract

The invention discloses a detection control method for a wireless detonator detonation network, and belongs to the technical field of ore body blasting demolition, and the method comprises the following steps: S1, a detonation network electrically controls a plurality of electronic detonators at the same time in a serial arrangement mode; s2, an auxiliary circuit system is installed on a line site between two corresponding adjacent electronic detonators on the detonation network, and the multiple auxiliary circuit systems are coded; and S3, before electrifying, the voltage detection equipment receives and detects a signal value sent by the auxiliary circuit system by using a wireless technology. In the invention, according to the measured secondary value change of the two-phase oscillogram, if the grounding fault occurs, the voltage amplitude is correspondingly reduced, and whether the grounding fault exists in a certain phase or not can be judged by judging the amplitude change of the voltage; the good detection of the sensitive and reliable detonating network has non-weight significance for the control of the wireless detonator.

Description

technical field [0001] The invention belongs to the technical field of ore body blasting demolition, and in particular relates to a detection and control method for a wireless detonator initiation network. Background technique [0002] The detonator is the main detonating material in blasting engineering. Its function is to generate detonating energy to detonate various explosives, detonating cords and detonating tubes. Detonators are divided into fire detonators and electric detonators. Electric detonators are used in underground coal mines. Electric detonators are divided into instantaneous detonators and delayed electric detonators. Delay electric detonators are divided into second delay electric detonators and millisecond delay electric detonators. The detection content of the wireless detonator detonation network in the prior art includes overvoltage, grounding and overload. If grounding occurs, it is easy to cause the wireless detonator detonation network to fail to ...

Electric detonators are used in underground coal mines

Delay electric detonators are divided into second delay electric detonators and millisecond delay electric detonators. The detection content of the wireless detonator detonation network in the prior art includes overvoltage, grounding and overload. If grounding occurs, it is easy to cause the wireless detonator detonation network to fail to work normally Seriously, it will cause the failure of the wireless detonator, and serious accidents will occur. A detection and control method for the detonation network of the wireless detonator is proposed.
