Electronic digital detonator remote blast system and method thereof

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.
