Definitions

  • the invention relates to an electrical firing device for weapon systems with a firing logic generating the firing signal, which can be controlled from at least one firing button and the output of which is connected to the control input of a controllable electronic power switching element via which an ignition device can be connected to an electrical supply circuit.
  • a firing device in which, as mentioned at the outset, an electronic switching element is used to switch the current pulse causing the ignition, is known from DE-A-2 046 098. It is a circuit arrangement for rocket launchers in which the ignition pulses are passed on via thyristors.
  • a circuit arrangement for securing electrically operated weapon systems is known from DE-A-27 03 803.
  • this known circuit arrangement it is possible to define the "safe” and “ready to fire” states of a weapon system by means of electrical switching states, in such a way that the weapon system automatically changes to the "safe” state in the event of any malfunction or incorrect operation but the path between the electrical supply circuit and the ignition device is not included, so that this safety circuit also cannot prevent the uncontrolled breaking of the shot when the electronic switching element fails.
  • the object underlying the invention was to create a firing device of the type mentioned at the outset which meets all the safety requirements with regard to uncontrolled firing.
  • a second controllable switching element is arranged between the electronic switch and the ignition device, which can be controlled via a safety circuit which has a switching device in which the second switching element is opened in one switching position and the second is switched in the other switching position Switching element is closed.
  • the control of the electronic switch via a safety circuit which can be done in such a way that the path between the supply circuit and the ignition device is only released for a short time, ensures that even if the electronic switch is defective, the shot is broken at the wrong time.
  • the second controllable switching element itself does not have to switch the high current pulse, but only has to transmit it, the requirements for the properties of this second switching element are less stringent than for the power switching element.
  • a thyristor or a power transistor or a combination of transistors can be used as the power switching element.
  • a relay can serve as the second controllable switching element (claim 3), but an electronic switch can also be used at this point, which is justifiable at this point, taking into account the safety regulations, since a simultaneous and Similar defects on the two electronic switches arranged in the same branch are very unlikely to occur and electronic switches have a longer service life with regard to the number of switching operations.
  • a particularly advantageous embodiment of the firing device according to the invention is the subject of claim 2. This ensures that the second switching element is generally open and this state is immediately restored shortly after the firing signal has been given, regardless of whether the shot actually broke or whether a There is a defect.
  • a Fire logic 2 can be connected to the supply voltage 5 via a fire button 1.
  • the button signal flows into the firing logic 2.
  • This sends a firing signal via an amplifying transistor Tr3 and a Z diode to the control input 3a of an electronic switch, which is denoted by 3 in FIG. 1 and consists of two in the selected exemplary embodiment Transistors Tr1 and Tr2 in Darlington circuit.
  • a thyristor can also be used as the electronic switch 3 at this point, for example.
  • the supply voltage applied to the electronic switch 3 from the voltage source 5 is switched through when the electronic switch 3 is switched on and reaches the ignition device 4 via the resistors R1 and R2 when the relay contact a1 of a relay A is closed.
  • Relay A belongs to a safety circuit that can be operated from two buttons 6 and 7.
  • the "Ready to fire” state is set by pressing the button 6 and the "Safe” state is set by the 7 button.
  • the button 6 is pressed briefly, a current flows through the relay A, which pulls it in, whereupon it is held via a self-holding circuit consisting of the closed button 7, the relay contact a2 and a diode D2 which protects against incorrect polarity.
  • the diode D1 is used to reduce the fall time of relay A.
  • the self-holding circuit When the button 7 is pressed, the self-holding circuit is briefly interrupted and the relay returns to the idle state by opening the contact a1. The circuit is thus again in the “safe” state and no firing pulses can reach the ignition device 4.
  • the safety circuit also contains a time switching device 8 which, after a predetermined time interval has elapsed after the firing pulse has been applied to the electronic switch 3, opens the latching circuit of relay A via a control transistor Tr4 and thus automatically restores the state “safe with open contact a1”. This restoration of the “safe” state also takes place if, for example as a result of a defect, the voltage at the output of the electronic switch 3 is maintained after the firing signal is given as a result of a defect. This ensures the highest level of security.
  • Resistors R1 and R2 limit the current to the maximum permissible value for electronic switch 3.
  • FIG. 2 The embodiment of a firing device shown in FIG. 2 corresponds in principle to the embodiment according to FIG. 1. For this reason, the same switching elements are provided with the same reference numerals.
  • the fire logic 2 can be connected to the voltage supply 5 via the fire button 1.
  • the firing button 1 When the firing button 1 is actuated, the firing signal 2 passes from the firing logic 2 to the control input 3a of the electronic switch 3 via the transistor Tr3 and the Zener diode.
  • switching through the firing signal to the ignition device 4 is only possible if a second electronic switch 9 is transparent is controlled.
  • This second electronic switch 9 also consists of two transistors Tr5 and Tr6. An opening or closing signal can be fed to its control input 9a, which is either emitted by the two buttons 6 and 7 for the “ready to fire” or “safe” state or by the timer 8.
  • the “ready to fire” state is established by briefly pressing the button 6.
  • the triggered pulse is sent via a NAND gate N1 to the set input 10a of a bistable multivibrator 10, the output 10c of which is connected via a control transistor Tr 7 to the control input 9a of the electronic switch 9 connected is. If the bistable flip-flop 10 is set, it controls the second electronic switch 9 so that a firing signal coming from the first electronic switch 3 can reach the ignition device 4 in this switching state.
  • a reset signal from the time switching device 8 via the NAND gate N2 likewise reaches the bistable flip-flop 10 after a predetermined period of time, which likewise restores the “safe” state.
