ELECTRONIC DETONATOR AND METHOD OF OPERATION THEREOF

摘要

A method of operating a detonator (24) which includes the steps of obtaining a calibration count using an oscillator (32) with an unknown but stable frequency in the detonator (24) as a reference, over a calibration time period, storing the calibration count in a memory in the detonator (24), transferring a delay time period to the detonator (24) and, in the detonator (24), generating a delay time count, which is related to the delay time period, using the calibration count, the calibration time period, and the delay time period.
