Definitions

  • the invention relates to a method for the temping of an ammunition unit according to the preamble of patent claim 1 and a heatable ammunition unit.
  • ammunition-specific data i.a. the type of ammunition, lot number, date of manufacture, etc.
  • ammunition data chip located in the ammunition unit.
  • These data are automatically read when the ammunition unit is placed in a cargo space of a weapon system. The reading is often done by a fire control computer of the weapon system. This then generates, taking into account ammunition-specific and target-specific data, direction signals for the straightening system of the weapon as well as control signals for activating an electrically programmable projectile fuze arranged in the respective cartridge or ammunition unit.
  • US 4,577,561 discloses a method and apparatus for digital fuze programming. From this is a Tempierelektronik, consisting of a demodulator and a microprocessor, known.
  • DE 198 27 378 A1 discloses a weapon system with a fire control system and a generic ammunition unit which can be fired from a weapon.
  • a bidirectional data transmission via the two required for voltage and power supply of the electronic circuit devices of the respective ammunition unit lines.
  • the data transmission from the fire control system to the electronic switching device in the ammunition unit by means of modulation of the voltage signals of the supply voltage.
  • the feedback to the fire control system is realized by means of modulation of the current signals of the operating current.
  • a converter is connected between the fire control system and the electronic switching device.
  • the tempier data for setting the detonator are transmitted analogously.
  • the temping is then acknowledged by a brief increase in the operating current.
  • Disadvantages of such an analogue temping include the necessary additional tempier signals, which must be provided by a dedicated hardware and software.
  • the temping accuracy is determined by the hardware.
  • the present invention addresses the problem, namely, to exclude the disadvantages known in an analogue temping.
  • the invention is based on the idea of providing a digital data transmission of the tempier data in a heatable ammunition unit, for which purpose these data are transmitted, for example, with an HDB-3 (high density bipolar) transmission code and by means of voltage modulation.
  • HDB-3 high density bipolar
  • the HDB-3 code is preceded by a start byte and a stop byte, which are thus part of the tempier data.
  • the tempier time is transmitted numerically between the start and stop bytes as a data byte.
  • the start and stop bytes differ from all other bit patterns in the weapon system in order to realize a clear identification of the start and stop signal.
  • the start byte begins and the stop byte preferably ends with positive modulation pulses. This prevents the beginning as well as the end of a data transmission from being erroneously initiated or terminated by short-term line interruption or supply voltage drops.
  • the ammunition unit on a Tempier electronics which includes a (voltage) demodulator, a (current) modulator and a microprocessor with an RC oscillator clock counter, an RC oscillator, a Tempiercampuser and an actuator Encase.
  • 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 is integrated between the ammunition unit and a weapon that can be fired on the ammunition unit.
  • a DC-free voltage and current modulation and a continuous synchronization of the data transmission interface is achieved.
  • the DC-free modulation allows in continuation of the invention, the simultaneous transmission of the Tempier poems as well as the voltage and current data on an existing connection line for the power supply of the Tempier electronics, including the supply voltage and the output current from the MCS example, remain constant in the average.
  • a time-synchronous detection of start and stop bytes can be realized by an interrupt-controlled evaluation of the signals from a voltage demodulator by microprocessor and software in the Tempier electronics (generation of a counter gate).
  • the digital transmission of the tempier data allows the continuation of the invention, the consideration of the properties of a necessary for tempo TaktOszillators (time base) in the Tempier electronics.
  • Frequency instability as well as aging phenomena can be briefly compensated by determining the oscillator clock rate and by calculating a time-corrected Tempier setpoint, so that a power-saving and shot-resistant RC oscillator can be used.
  • the time base in the Tempier electronics is calibrated using the data transmission rate (baud rate), with the transmission of one Quartz oscillator in the MKS to the RC oscillator in the Tempier electronics quartz accurate.
  • the feedback on the current and corrected programmed tempier data is provided by means of a digital supply current modulation of the programmed tempier data.
  • 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 system control. This allows a check in the MKS to see if the temping and time correction have been properly performed.
  • the advantage of digital temping also lies in the fact that the tempier accuracy can be made variable by software, since it is not subject to any hardware-dependent dependency.
  • the temping accuracy can be adjusted for example by selecting the data transmission time.
  • a writable ammunition data chip within the ammunition unit, it is also ensured that the same data and voltage transfer can be used for the MDC as well as the spark timing. D. h., The structural and software expense remains low.
  • the advantage of a writable MDC is i.a. in that, for example, aging phenomena of the ammunition can be compensated on the basis of empirical values.
  • electrical assemblies of the Tempier electronics may form 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 is shown.
  • the ammunition unit 3 comprises a Tempier electronics 4, which is electrically connected to an igniter 5 of the ammunition unit 3.
  • the data-providing unit 1 here is preferably 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 for the supply voltage and responsible for 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 other, for 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 of these assemblies 20 -22 and a quartz oscillator 24 are connected to a microprocessor 25 with a quartz oscillator clock counter 25.1.
  • the voltage supply 20 is furthermore connected on the output side to a current demodulator 23, which accesses the microprocessor 25 with two connections.
  • a further, preferably bidirectionally operating line of the current demodulator 23 leads in extension as line B1 to the ammunition unit 3.
  • the DC / DC converter and the microprocessor 25 each have a connection to a necessary mass, the ammunition unit via line B2 3 connects to the mass.
  • Tempier electronics 4 is shown in more detail, with only the essential components are named here. 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 are summarized in Figure 1 by the reference numeral 7, are required for programming in the programming phase. For the flight phase, an RC oscillator 33, a tempier counter 34 and an actuator power stage 36 are responsible, which were summarized in Figure 1 by the reference numeral 8. Also shown is a firing sensor 35 which acts as a trigger of the programmed tempier time at the beginning of the flight phase. For the sake of functionality, a voltage regulator 37 is shown, which, however, will not be described in detail.
  • the temping is as follows:
  • the ammunition-specific data are automatically read out into the fire control computer 1. This determines the necessary temping time for the igniter 5. This information is forwarded to the MKS 2, in which these data are coded by means of microprocessor 25 and the voltage modulation module 20 (HBD-3 code), the coded tempier time pre-set a start byte and appending a stop byte different from the data word of the code.
  • the coded signal (see FIG. 4) is transmitted at a baud rate derived from the frequency (clocks) of the quartz oscillator 24 of the MKS 2, counted in the quartz oscillator clock counter 25. 1, and thus precisely defined in time Tempier electronics 4 transmitted and read into the microprocessor 32.
  • the clocks of the RC oscillator 33 between the start and stop bytes are measured with the RC oscillator clock counter 32.1. In principle, this would end the programming of the tempier data.
  • T ÜB 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 realized by the quartz-precise microprocessor control in the MKS 2.
  • T SHOULD RC T ⁇ 1 - n / T UB ⁇ fuze-timing
  • 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 35 is a release for the tempier counter 34.
  • This then counts with the RC oscillator clock from tempêtmpier setpoint T SOLL from the RC oscillator clock counter 32.1, for example, back to zero and triggers when reaching 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 .
