Definitions

  • the present invention relates to a time fuse arranged in a projectile tip according to the preamble of patent claim 1.
  • Such a timer is known from US-A 4147 109.
  • a time fuse arranged in a top of the floor is provided with means for programming and a viewing window in the top of the floor serves to partially visualize the programmed value.
  • a program tape which is scanned and used to set a binary counter, is used to program the seconds, tens and hundreds.
  • the programming tape carries a scannable code on one side and an unencrypted numerical value on the other side, which can be read in a window.
  • This programming tape is used for the rough setting (0 to 200 seconds) and an additional setting ring acts via contacts on another adjustable counter to set the tenths of a second. This setting must be read separately on the setting ring. Both settings are made purely mechanically and therefore it is not possible to check whether the counters are set to the codes specified by the mechanical programming device. In particular, when the projectile carrying the time fuse is fired, there is a risk of the set value being adjusted.
  • LED light-emitting diode
  • a projectile tip 10 is provided with a viewing window 12 in which a numerical display 14 is visible within the projectile tip.
  • the numerical display 14 is actuated by an adjusting ring 16 which cooperates with a contact, not shown.
  • the set time is displayed in seconds so that the first digit shows the hundreds seconds and the digit after the decimal point the centiseconds.
  • the projectile tip 10 consists of a metallic housing 18 in the rear part and a plastic housing 20 in the front part.
  • the front part 20 has a central recess 24 which receives a lithium primary battery 28.
  • the electronics 30 controls the number display 14, the numbers of which are visible through the window 12 to the outside.
  • the numerical display 14 is actuated by turning the adjusting ring 16 up to a stop, as a result of which a contact interacting with the electronics 30 is actuated.
  • a receiving coil 32 is arranged in the plastic part 20 concentrically to the projectile axis and is also connected to the central electronics 30 in a manner not shown.
  • the time fuse can be programmed electrically-inductively via this receiving coil 32.
  • a mechanical device 34 is arranged, which in a manner known per se comprises a safety device and an interface block containing an ignition means and the switches required for the ignition means short circuit and the firing sensor.
  • FIG 3 essentially shows the elements of Figure 2 in a block diagram.
  • the central component of the time fuse is the central electronics 30, which has a microcomputer and is fed by the primary battery 28.
  • the primary battery 28 feeds an ignition circuit 36 when it is actuated by the central electronics 30.
  • the ignition circuit 36 can first open after the projectile has been fired via the safety device 34 act an igniter.
  • a detonator running time can be set in the central electronics 30 electrically-inductively via the receiving coil 32 or by hand by corresponding actuation of the setting ring 16 and controlled by the numerical display 14.
  • FIG. 4 shows the central electronics 30 in more detail. The basic structure and function of the circuit arrangement shown are described below:
  • the bit pattern corresponding to the running time and predetermined by the programming sequence can be read in serially at the connection 30 of the microcomputer D2 via a programming logic having the components V16, R17 and C9.
  • a frequency of 100 kHz is still received by the programming device.
  • VMOS transistor V18 is cyclically controlled via output 28 of microcomputer D2.
  • the resulting short circuit on the resonant circuit L2 / C11 is sensed via the phase shift in the transmitter coil of the programming device as information output by the microcomputer D2 and compared with the setting on the programming device (talkback), whereupon the result of the programming is displayed as positive or negative.
  • the alternating magnetic field output by the programming device is then switched off.
  • the VMOS transistor V13 which is driven by the output 27 of the microcomputer D2, ensures the voltage supply of the microcomputer D2 until the predetermined information storage time has expired.
  • the running time is set manually via the setting ring 16, which is represented in FIG. 4 by the switching contact S1.
  • the VMOS transistor V12 and thus the transistor V4 are turned on via the adjusting ring S1 and the diode V8 and the microcomputer D2 is supplied with energy from the primary battery G1-28 at the connection 44.
  • the VMOS transistor V13 is controlled via the output 27 of the microcomputer D2, and the switch-on time of the supply voltage is thus determined via V4 via the microcomputer D2.
  • the runtime information can be entered. If the above sequence is not followed, i.e. If, for example, only three digits are set, the program of the detonators automatically sets itself to runtime 000.0, and there is no function in the event of a possible launch.
  • the display segments of an LED display can be controlled.
  • This display is implemented in such a way that the transistors V24-V31 for the seven segments and the decimal point are activated in succession via the outputs 6-12 and 19 of the microcomputer D2.
  • the transistors V19-V22 are selected for the respective decimal place via the outputs 13-16 of the microcomputer D2.
  • the transistors V19-V22 each switch the light-emitting diode segments LED1-LED7 for one decimal place and one light-emitting diode segment LED8 for the decimal point to the operating voltage, provided that the transistor V24-V31 connected in series with the light-emitting diode segments is also controlled by the microcomputer D2.
  • These transistors V24-V31 are activated in order to save energy.
  • the flight information is saved for a certain time, just like after inductive programming. This is done via the output 27 of the microcomputer D2 and via the elements R14, V13, R3, R4, C4 and V4. After the end of the storage time, the output 27 of the microcomputer D2 is set to zero and the entire energy supply is thereby switched off via the transistor V4. Over-programming by hand or inductively is possible for everyone.
  • the switch S2 is closed via the mechanical security device, which is sensed at the input 29 of the microcomputer D2.
  • An impact function is not provided in the exemplary embodiment, but is possible in itself.
  • a safety oscillator D1 is interrogated cyclically at the input 33 of the microcomputer D2 and compared with the main oscillator G2, R16, C7, C8 in order to prevent premature ignition by a defective quartz crystal G2.
  • the VMOS transistor V14 and the transistor V1 are switched on via the output 26 of the microcomputer D2 to generate the ignition energy, whereupon the battery voltage is switched through to the ignition circuit.
  • the ignition capacitor C3 is charged by cyclically actuating the transistor V14 via the output 25 of the microcomputer D2.
  • a voltage limitation of the capacitor C3 is ensured by the Zener diode V5, which is connected in parallel with the capacitor.
  • the manual setting of the runtime which is provided as an emergency function, is carried out in the manner listed below. It should be noted here that the contact actuated by the adjusting ring is not closed (“OFF") when the adjusting ring is in the clockwise direction as viewed from the tip. On the other hand, the contact is actuated by the adjusting ring ("ON") when the adjusting ring has been turned counterclockwise as far as it will go.
