Definitions

  • the invention relates to a device for monitoring the initiation of an active system, comprising at least one sensor in the field of explosive charge and / or at least one ignition device for the explosive charge of the active system, and a control device for evaluating the sensor output signals with at least one ignition device in accordance with controlling the evaluation is connected.
  • the DE 10 2012 006 044 B3 describes such a method and a device suitable for this, with the aid of which, after the initiation of a deflagration of the explosive charge, the ignition time of a further ignition chain can also be determined. From the application of such an active system, there are specific requirements for the ignition system in order to ensure, when selecting a subdetonative mode of action with high functional reliability, that there is at least no greater implementation of the explosive charge than the one selected.
  • the DE 10 2014 004 003 B3 describes an ignition system for a power-scalable active system with two different ignition circuits for the subdetonative and detonative initiation of the explosive system of the active system, whereby a control mechanism in the subdatational ignition circuit monitors the correct function and thus prevents the uncontrolled full power output of the active charge.
  • the present invention is therefore based on the object to increase the reliability of the ignition system with respect to previously known with the aid of suitable measures for a lack of subdetonative reaction such as a deflagration.
  • At least one sensor is arranged at the output of a first ignition device for the subdetonative initiation of the explosive charge, that the control device is connected to a further ignition device and this in accordance with the signal supplied by the sensor and evaluated in the control device free or blocks that at least one sensor for the detection of pressure, temperature, light, electric current or change of mechanical conditions is designed, and that the sensor detects the pyrotechnic event of deflagrativen implementation of the explosive charge by means of suitable physical quantities.
  • a sensor which detects the pyrotechnic event of the deflagrative conversion of the explosive charge by means of suitable physical quantities can lead to a further improvement in the reliability of the ignition system and the active part.
  • the functional reliability of the ignition system can be influenced both by circuitry and by suitable selection of the electrical components and the one-shot devices such as detonators and Exploding Foil Initiator (EFIs).
  • EFIs Exploding Foil Initiator
  • the measures described below focus primarily on the first case.
  • the measuring device can advantageously be combined with the fact that the high-voltage circuit for the detonator is first armed and supplied with voltage as soon as the deflagration event has been positively sensed. Also, the high voltage ignition circuits for deflagrator and detonator can be connected to the high voltage converter in a master-slave arrangement.
  • Such measures can finally increase the reliability of the function in order to prevent a higher performance of the active system than originally selected or intended. They also offer the advantage that they can be carried out either directly in or in the vicinity of the ignition system.
  • FIG. 1 is shown schematically simplified a block diagram of the device according to the invention.
  • a high-voltage power supply unit HS-NT not only supplies the control system ZS-ST for the ignition system, but also both ignition systems ZS-A and ZS-B, the EFI's EFI and the ignition chains ZK-A and ZK-B.
  • the ZS-ST control unit carries out various tasks in the context of the safe ignition triggering or the reduction of dangers in the event of a malfunction in the subdetonative initiation of the explosive charge.
  • the time-controlled distribution of electrical energy in the form of low voltage and high voltage to supply the modules is performed. From here to the other control signals are sent to all modules involved and evaluated the answers received from there.
  • the output signal of the sensor ZK-A-Ü is evaluated, which monitors the function of the first ignition ZK-A. Only when the proper function of this ignition chain is confirmed does the control device generate an enable signal for the further ignition system ZS-B and the further ignition chain ZK-B. If one of the modules fails, the detonative initiation of the explosive charge is consistently prevented.
  • FIG. 2 represents greatly simplified, the local position of the assemblies in a possible embodiment of an ignition system according to the invention.
  • the power supply HS-NT visible, next to the control unit ZS-ST.
  • the left follow the different intensity levels of the two ignition chains. Far left, the unillustrated explosive charge would be placed.
