An electronic digital detonator remote explosion system and method thereof

Abstract

The invention discloses an electronic digital detonator remote detonation system and a method thereof. The electronic digital detonator remote detonation system includes an encoder, a decoder and an initiator; Send it to the decoder; when the decoder detects that the detonation preparation is complete, it forms a closed loop according to the excitation command and generates a high-voltage pulse signal to the detonator; when the detonator detects the rising edge of the high-voltage pulse signal, it outputs the detonation pulse to control the electronic digital signal. The detonator detonates; at the same time, the electronic digital detonator returns the CTB pulse to the detonator before the instant of detonation; the detonator controls the decoder to form a discharge circuit according to the simulated CTB pulse, and the decoder generates a CTB signal to the encoder; a closed loop is adopted The unique detonation control method can solve the effect of unstable error in the detonation process of the exploration detonator, and greatly improve the consistency requirements between the detonation of the address exploration and the signal acquisition.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to an electronic digital detonator remote blasting system and a method thereof. Background technique [0002] The remote explosion system used in oil exploration is mainly composed of seismograph, PC, encoder, decoder and so on. The synchronization index of encoder and decoder is the key parameter of the remote explosion system. Since the existing remote detonation system is specially designed for electric detonators, the standard design of electric detonators is adopted in the detonation mode, operation mode and networking mode. The detonation method, operation mode, and networking method of electronic digital detonators are very different from those of electric detonators. In order to meet the demand for electronic digital detonators in seismic exploration, on the basis of the existing geophysical remote detonation system, without changing the encoder and decoder, ...
