摘要： Method and systems of controlling detonation of a plurality of explosive charges. A controller has a magneto-inductive transmitter to transmit a magneto-inductive signal to a plurality of detonators, each having a receiver to receive the magneto-inductive signal and a respective firing delay time. The method includes, at each of the plurality of detonators, receiving, via the magneto-inductive signal from the magneto-inductive transmitter, a time sync signal; synchronizing a local clock in the detonator based on the time sync signal; receiving, via the magneto-inductive signal from the magneto-inductive transmitter, a firing code; waiting the respective firing delay time from receipt of the firing code, wherein the waiting is clocked by the local clock; and after expiry of the respective firing delay time, triggering a respective explosive associated with the detonator.
