Definitions

  • the present invention relates to a method for detecting the firing of a projectile according to the preamble of claim 1 and to an apparatus for performing this method.
  • microprocessor D2 which generates the corresponding actuation signals for a charging circuit and an ignition circuit by querying a launch switch S2 and a rotation switch S3. It is of additional importance that the launch switch S2 also forms the impact switch. Such a switch, which can detect both positive and negative accelerations, is commercially available.
  • the input / output terminal 24 is connected to an ignition circuit which has a thyristor V2 which can be controlled via a diode V9 and a filter element R7, C7.
  • the input / output connection 25 drives a VMOS transistor V12 rhythmically via a resistor R14 and the input / output connection 26 switches a transistor V1 via a resistor R13 and a VMOS transistor V11 and resistors R2, R6 the connection A and ground connected operating voltage source U Bat to a Locking oscillator circuit creates.
  • This blocking oscillator circuit comprises, connected in series, a coil L1 and a diode V5 and the rhythmically operated transistor V12 connected between these two elements, in order to charge an ignition capacitor C4 to a highly transformed DC voltage.
  • the voltage of the ignition capacitor C4 is limited by a Zener diode V8 and the charge of the ignition capacitor C4 can discharge when the blocking oscillator is switched off via a parallel-connected high-resistance resistor R10. In the event of an ignition, the ignition capacitor C4 is discharged via the thyristor V2 onto a detonator in order to ignite the projectile when the projectile hits or an elapsed delay time.
  • the input / output connection 29 is set to a corresponding potential in order to trigger the ignition by actuating the thyristor V2 when the open switch S2 is actuated.
  • the input / output connection 32 is only signaled the actuation of the rotation switch S3.
  • the function of the circuit arrangement described above is as follows: When the supply voltage + V is applied to the microprocessor D2, it is initialized. After an initialization time of approximately 5 ms, the connections 32 and 29 of the microprocessor are set to input (high-resistance), and the connection 24 is set to output with the logic level "0".
  • the contact of this switch is closed, and the logic level at input 29 is set to logic "0" by output 24, which is sensed by the microprocessor.
  • the flight time of the projectile fuse is started in the microprocessor.
  • the rotary switch S3 now switches within 10 ms, which is sensed at the connection 32 of the microprocessor.
  • the short-circuit of the ignition means is thereby eliminated.
  • the rotary switch S3 is polled several times by the microprocessor. Only if the rotary switch S3 is still closed after this time is this evaluated as a launch. After that, contact is no longer necessary. In this way, short impulses are disregarded.
  • the ignition capacitor C4 is charged by appropriate control via the connections 25 and 26, and the connection 24 of the microprocessor becomes input (high-resistance) and the connection 29 set to output with logic level "1".
  • thyristor V2 is not ignited by this logic level "1" since the open switch S2 is open.
  • the switch S2 is closed during the launch and remains closed until the projectile leaves the launch tube. Then switch S2 opens so that it can act as an impact switch.
  • the switch S2 When the projectile hits a target, the switch S2 is closed by the negative acceleration acting on it and the "1" signal present at the connection 29 is switched through to the trigger input of the thyristor V2.
  • the ignition capacitor C4 is discharged into the detonator by the ignition of the thyristor V2 and the ignition is initiated. In both cases it must be ensured that the detonator is not short-circuited by the rotary switch S3.
  • terminal 24 After firing up to the point in time "end of runtime minus 3.4 s", terminal 24 remains at logic level "0". Ignition of the detonator is thus prevented even if the switch S2 is actuated by this time.
  • the ignition capacitor C4 At the point in time “end of running time minus 3.4 s", the ignition capacitor C4 is charged, which in turn takes place via the control through the connections 25 and 26, and the surcharge function becomes by switching the connection 24 to input (high-resistance) and the connection 29 released on output with logic level "1".
  • the terminal 24 After the set time, the terminal 24 is set to output with logic level "1", which triggers the trigger input of the thyristor V2 and the detonator is ignited.
  • ignition of the projectile detonator can also be initiated by impact switch S2.
