Definitions

  • the invention relates to a method for temping an ammunition unit after Preamble of claim 1 and a malleable ammunition unit.
  • Ammunition identification of an ammunition unit is ammunition-specific data, et al the type of ammunition, lot number, date of manufacture etc., directly on a in the Ammunition stored data storage (ammunition data chip). These Data is automatically read when the ammunition unit is in a cargo space a weapon system is introduced. Reading out is often done by one Fire control computer of the weapon system. This then generates under consideration Ammunition-specific and target-specific data Guidance signals for the straightening system the weapon and control signals to Akivi réelle a in the respective cartridge or ammunition unit arranged electrically programmable projectile fuze.
  • the present invention addresses the problem, namely, in an analog Temping to exclude known disadvantages.
  • the invention is based on the idea of a digital data transmission of the tempier data provide in a malleable ammunition unit, including this data, for example with a HDB - 3 (high density bipolar) transmission code and by means of Voltage modulation can be transmitted.
  • the HDB-3 code is as with asynchronous Data transfer known, a start byte before and a stop byte added, which are thus part of the tempier data.
  • the tempier time will be between the Start and stop bytes transmitted numerically as data byte.
  • the start and stop bytes differ from all other bit patterns in Weapon system to provide a clear identification of the start and stop signal realize.
  • the start byte starts and the stop byte preferably ends with positive Modulation pulses. This will prevent both the beginning and the end a data transmission by mistake due to short-term line interruption or Supply voltage drops may be initiated or completed.
  • the ammunition unit has a Tempier electronics, the (voltage) Demodulator, a (current) modulator and a microprocessor with an RC oscillator clock counter, an RC oscillator, a tempier counter and an actuator power amplifier includes.
  • a firing sensor serves as a trigger element of the Tempierfarers at the beginning of the flight phase. The digitization of the tempier data takes place in an ammunition communication system, which between the ammunition unit and a the ammunition unit is lockable weapon.
  • a time-synchronous detection of start and stop bytes can be interrupted by an interrupt Controlled evaluation of the signals from a voltage demodulator by microprocessor and software in the Tempier electronics are realized (generation a countergate).
  • the digital transmission of the Tempier poems allowed in continuation of the invention the consideration of the properties of a clock oscillator necessary for temping (Time base) in the Tempier electronics.
  • Frequency instability as well as aging phenomena can by determining the oscillator clock rate and by calculation a time-corrected Tempier set point be compensated for a short time, so that a power-saving and shot-resistant RC oscillator can be used can.
  • the time base in the Tempier electronics is using the data transfer rate Calibrated (baud rate), the transmission of a Quartz oscillator in the MKS to the RC oscillator in the Tempier electronics quartz-accurate he follows.
  • the feedback on the current and corrected programmed tempier data is programmed by means of a digital supply current modulation Tempier poems provided.
  • the data transmission is bidirectional.
  • the feedback of the programmed time-corrected Tempier setpoint and the Number of RC oscillator clock rate can also be used for a system control. This allows a check in the MKS, whether the temping and time correction been carried out properly.
  • Another control of data transmission is by examining the number of transmitted bits as well as given by a checksum.
  • the advantage of digital temping is also that the tempier accuracy can be made variable by software, since they have no hardware dependency subject.
  • the Tempiergenaumaschine can be, for example, by the choice set the data transmission time.
  • a writable ammunition data chips within the ammunition unit also ensures that a same Data and voltage transfer for the MDC as well as the ignition timing can be used. D. h., The structural and software expense remains low.
  • the advantage of a writable MDC is i.a. in that, for example The aging effects of the ammunition are compensated on the basis of empirical values can be.
  • electrical components of the Tempier electronics make up the MDC.
  • Fig. 1 is a schematic representation of the general structure of a weapon system with a data providing unit 1, an ammunition communication system (MKS) 2 and an ammunition unit 3 shown.
  • the ammunition unit 3 comprises a Tempier electronics 4, which with an igniter 5 of the ammunition unit. 3 electrically connected.
  • the data supplying unit 1 is preferred here a fire control computer.
  • the Feuerleitrechner 1 is electrically connected via a data line A1, a CAN bus, and to provide a voltage and power supply U S , I S via a further line A2 to the MKS 2.
  • the electrical connection between the MKS 2 and the ammunition unit 3 is provided via the lines B1 and B2, wherein the line B2 represents a ground line and the line B1 responsible for the supply voltage and the data transfer to the ammunition unit 3.
  • the Tempier electronics 4 comprises electrical modules 7 for the programming phase and electrical assemblies 8 for the flight phase.
  • FIG. 1 A general structure of the MKS 2 is shown in FIG. 1
  • the MKS 2 has, among others, for the sake of clarity not shown Assemblies a voltage supply with voltage modulation 20, a CAN bus interface 21 and a DC / DC converter 22. Outputs and inputs These assemblies 20 -22 and a quartz oscillator 24 are provided with a Microprocessor 25 connected to a quartz oscillator clock counter 25.1.
  • the Power supply 20 is also the output side with a current demodulator 23 connected, with two connections to the microprocessor 25th accesses. Another, preferably bidirectionally operating line of the current demodulator 23 leads in extension as line B1 to the ammunition unit 3.
  • the DC / DC converters as well as the microprocessor 25 each have a connection on a necessary mass, via the line B2, the ammunition unit 3 with the Mass connects.
  • Tempier electronics 4 is shown in more detail, with only the essential Assemblies are named. These are a voltage demodulator 30, a Current modulator 31 and a microprocessor 32 with an RC oscillator clock counter 32.1. These assemblies 30-32, which summarized in Figure 1 under the reference numeral 7 are required for programming in the programming phase. For the flight phase show an RC oscillator 33, a Tempiercrofter 34 and an actuator Engame 36 responsible, which summarized in Figure 1 by the reference numeral 8 were. Also shown is a firing sensor 35 which acts as a trigger the programmed tempo time at the beginning of the flight phase. The functionality Half a voltage regulator 37 is shown, but not described in detail becomes.
  • the temping is as follows:
  • the ammunition-specific data becomes automatic read out into the fire control computer 1. This determines the necessary tempier time for the detonator 5.
  • This information is forwarded to the MKS 2, in which this data by means of microprocessor 25 and the voltage modulation module 20 encoded (HBD-3 code), wherein the encoded tempier time a Start byte prefixed and a stop byte is appended, which is derived from the data word of the code.
  • the coded signal (see Fig. 4) is at a baud rate derived from the frequency (clocks) of the quartz oscillator 24 of the MKS 2 derived is counted in the quartz oscillator clock counter 25. 1, and thus defined in time transferred exactly to the Tempier electronics 4 and read into the microprocessor 32 becomes.
  • a problem that can arise in digital temping when a energy-saving and firing RC oscillator as a clock oscillator 33 in the ammunition device 3 is that the accuracy of the programmed Tempierzeit, due to the poor quality of these types of oscillators, insufficient becomes.
  • a transmission time T ÜB is calculated with the microprocessor 32 of the Tempier electronics 4. This results from the transmitted data bytes "number of transmitted bits" and "baud rate", which are written as information in the programming in the microprocessor 32 and in the data log of FIG. 4 are shown.
  • T UB number of transmitted bits / baud rate
  • the specified baud rate is controlled by the quartz-accurate microprocessor control MKS 2 realized.
  • the programming of the tempier counter 34 with the time-corrected T SOLL then results in an almost quartz precision, since the clock frequency of the RC oscillator 32 in the short phase of flight does not appreciably change.
  • the firing sensor outputs 35 a share for the tempos narrator 34.
  • This then counts the RC oscillator clock from tempi Erten tempos narrator setpoint T set from the RC oscillator clock counter 32.1, for example, down to zero and triggers when reaching over the actuator -End treat 36 the igniter 5 from.
  • the accuracy of the temping can also be adjusted by a specific choice of the data transmission time T ÜB .
