g r\ r O O &Pgr; «} U '-J' V? W U Ansprücheg r\ r O O &Pgr; «} U '-J' V? W U Claims 1. Kombiniertes elektronisches Explosionszündersystem mit einem Steuerteil zur Erzeugung und Ausgabe eines1. Combined electronic explosion igniter system with a control unit for generating and outputting a analogen Stromes und mit einem digitalen Steuerschaltungsteil, das aus einem Mikroprozessor mit einem eingebauten Speicher besteht, der den Vorgang leitet.
20analog current and a digital control circuit consisting of a microprocessor with a built-in memory that directs the process.
20 2. Verfahren zur Betätigung des Vorgangs des Systems nach Anspruch 1, das gemäß den folgenden Stufen ausgeführt wird:2. A method for operating the operation of the system according to claim 1, carried out according to the following steps: la Eingabe des Zugangs-Codes in das System, 2a Überprüfung der Verbindung der Linie der Zünder, 3a Eingabe der Basisverzögerungseinheit, 4a Scharfstellen oder Aktivieren der Zünder, 5a Zündung, wenn es weitergeht und die Reaktion auf die Überprüfung positiv ist, oder Entschärfen,la entering the access code to the system, 2a checking the connection of the detonator line, 3a entering the base delay unit, 4a arming or activating the detonators, 5a firing, if it continues and the response to the check is positive, or disarming, wenn das Verbindungs-Steuersystem einen Fehler oder einen falschen Status in irgendeinem der Zünder in der Linie feststellt.if the link control system detects a fault or incorrect status in any of the igniters in the line. 3. System und Betätigungsverfahren nach Anspruch 1 und 2, in welchem die Lieferströme zwei Spannungshöhen aufweisen, so daß die niedrigere Spannung zum Initiieren des Zünders oder Widerstandselementes unfähig ist und folglich als die Sicherungsspannung betrachtet wird.3. System and method of actuation according to claims 1 and 2, in which the supply currents have two voltage levels such that the lower voltage is incapable of initiating the igniter or resistive element and is thus considered to be the fuse voltage. 4. System und Betätigungsverfahren nach Anspruch 1, und 3, in welchem die Prüfstufe oder Prüfung aus einer Suche aller kodierten Richtlinien in jedem Zünder besteht, die vorbestimmt und über den Mikroprozessor eindeutig zur Verzögerungszeit jedes Zünders verbunden sind.4. A system and method of actuation according to claim 1, and 3, in which the test step or test consists of a search of all coded rules in each igniter which are predetermined and uniquely linked via the microprocessor to the delay time of each igniter. 5. System und Betätigungsverfahren nach Anspruch 1, 2, und 4, in welchem die maximale Sicherheit der Betätigung und Handhabung durch die Installation von geeignet angeordneten Relais erreicht ist, um den Zünder oder das Widerstandselement des Zünders bis zu dem Augenblick unmittelbar vor dem Schuß zu isolieren.5. System and method of actuation according to claims 1, 2, and 4, in which the maximum safety of actuation and handling is achieved by the installation of suitably arranged relays to isolate the detonator or the resistive element of the detonator until the moment immediately before the shot.
