Firing-readiness diagnostic of a pyrotechnic device such as an electronic detonator
View Patent ↗Firing-readiness diagnostics in an electronic pyrotechnic device such as an electronic detonator or an electronic blasting system thereof. The diagnostics may include a check for any incompatible attached devices, a resistance or continuity check of an ignition element, and/or a capacitance check of a firing capacitor.
1. An electronic detonator for use in mining or blasting and having firing-readiness diagnostics, comprising an igniter and electronic circuitry configured and/or programmed to perform one or more firing-readiness diagnostics on said electronic detonator, wherein said igniter includes an ignition element, and said electronic circuitry comprises a continuity check module.
2. An electronic detonator for use in mining or blasting and having firing-readiness diagnostics, comprising an igniter and electronic circuitry configured and/or programmed to perform one or more firing-readiness diagnostics on said electronic detonator, wherein said igniter includes an ignition element, and said electronic circuitry comprises a continuity check module, and wherein said electronic detonator includes an application-specific integrated circuit that contains said electronic circuitry.
3. An electronic detonator for use in mining or blasting and having firing-readiness diagnostics, comprising an igniter and electronic circuitry configured and/or programmed to perform one or more firing-readiness diagnostics on said electronic detonator, wherein said igniter includes an ignition element, and said electronic circuitry comprises a continuity check module, and wherein said electronic detonator includes an application-specific integrated circuit that contains said electronic circuitry, and wherein said igniter is hermetically sealed, and said ignition element is a bridgewire.
