Abstract
The invention discloses an electronic digital detonator remote blast system and a method thereof. The electronic digital detonator remote blast system comprises an encoder, a decoder and an exploder. The encoder converts a starting command sent by a seismometer into an excitation command of ignition and sends to the decoder. When detecting that detonation preparation is completed, the decoder forms a closed loop according to the excitation command and generates a high-voltage pulse signal to the exploder. When detecting a rising edge of the high-voltage pulse signal, the exploder outputs a detonation pulse so as to make an electronic digital detonator detonate. Simultaneously, the electronic digital detonator returns a CTB pulse to the exploder before a detonation moment. The exploder makes the decoder form a discharge loop according to a simulated CTB pulse. The decoder generates a CTB signal to the encoder. Through using a detonation control mode of the closed loop, an effect that an exploration detonator has an error and is not stable during a detonation process can be solved so that a consistency requirement between address exploration detonation and signal acquisition is greatly increased.

The invention provides the distant quick-fried system of a kind of electronic digital detonator and method thereof.For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, the distant quick-fried system of electronic digital detonator provided by the invention comprises scrambler 10, code translator 20 and initiator 30.Described scrambler 10 is connected with seismologic record instrument (hereinafter referred to as seismograph) communication, carries out communication between scrambler 10 and code translator 20 by wireless station.Described code translator 20 connects initiator 30, initiator 30 external connected electronic digital primer.
In the present embodiment, after initiator 30 completes the preliminary work before detonating, initiator wait for outside input high-voltage pulse signal (400V/4ms), namely can the mode of external interrupt to detonate operation.Be specially: seismograph sends startup command to scrambler 10.Scrambler 10 converts described startup command the instigation command of igniting to and sends to code translator 20 by radio station.Code translator 20 is detecting its built-in ARM(processor) switch being when having pressed and be in charging complete state, form closed loop according to this instigation command and the high-voltage pulse signal producing 400V/4ms to initiator 30; Meanwhile, TB signal is sent to seismograph by scrambler 10.When initiator detects the rising edge of high-voltage pulse signal, export pulse (high level pulse) of detonating and control electronic digital blasting cap initiation; Meanwhile, electronic digital detonator can return the CTB pulse of a simulation to initiator 30 before moment of detonating.Initiator 30 cut-offs state according to the CTB Pulse Width Control switch (switch S 1 namely in Fig. 2) of described simulation, makes 400V high-voltage pulse form loop in code translator 10 inside, thus makes code translator produce a CTB signal to scrambler.
Described CTB signal is very important for the distant quick-fried system of physical prospecting industry, and it directly reflects the net synchronization capability index of distant quick-fried system.Mistiming between the TB signal that scrambler 10 exports and the CTB signal that code translator 20 returns is defined as the CTB time.For on-site data gathering, require that the CTB time is less than a sampling period, the highest seismographic sampling period is 0.25ms at present.Therefore require that the CTB time returned must be less than a sampling period, this is the requirement to synchronization accuracy; Meanwhile, the maxima and minima of the CTB time that all code translators 20 requiring same project under construction to use return is more or less the same in a test sampling interval, and this is to conforming requirement.
