Abstract
Oppfinnelsen angår en elektronisk tenningsanordning som inneholder et energilagringselement (5) som kan utløses over et detoneringsmiddel eller en tennsats ved hjelp av en aktuator eller bryter (6) for å initiere antenning. Energilagringselementet (5) blir matet fra en spenningsforsyner (4) som tilveiebringer en lav spenning når den ikke er aktivert, hvilken lave spenning leveres til en datasryredel (DST). I en beredskapsmodus økes forsyningsspenningens (4) spenningsverdi til et nivå som er tilstrekkelig for at antenning kan finne sted. En sikkerhetskode er lagret i en informasjonsdel (IT) i et ikke-flyktig lager (11). Beredskapsmodusen kan bare initieres dersom signalet som føres over tilslutningsledningen (AL) er i overensstemmelse med sikkerhetskoden. Oppfinnelsen sikrer derfor at ikke-autoriserte personer som ikke kjenner sikkerhetskoden, ikke er i stand til å bruke tenningsanordningen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an electronic ignition device containing an energy storage element (5) which can be triggered over a detonating agent or ignition kit by means of an actuator or switch (6) to initiate ignition. The energy storage element (5) is fed from a voltage supply (4) which provides a low voltage when not activated, which low voltage is supplied to a data row part (DST). In a standby mode, the voltage value of the supply voltage (4) is increased to a level sufficient for ignition to take place. A security code is stored in an information part (IT) in a non-volatile memory (11). The standby mode can only be initiated if the signal transmitted over the connection line (AL) complies with the security code. The invention therefore ensures that unauthorized persons who do not know the security code are unable to use the ignition device.
