CALIBRATION OF DETONATORS |
摘要 |
A plurality of detonator assemblies in signal communication with a blasting machine, each detonator assembly consisting of a detonator, a storage compartment for storing programmed delay time and/or oscillation count and a countdown oscillator. A transmitter for transmitting a blast rehearsal stop start and stop signal, said signals being separated by said programmed delay time individually selected for each detonator signal. The oscillator counting the total oscillation count corresponding to said delay time. When a detonator assembly receives a FIRE command, the individual countdown oscillators countdowns the total oscillation count associated with its detonator assembly.
