Definitions
- the present invention relates to an electronic projectile detonator according to the preamble of claim 1.
- Modern electronic detonators nowadays use either primary cells or preferably batteries for energy supply, which are only mechanically and chemically activated by the high accelerations that occur when a projectile is fired.
- This has the advantage that igniters equipped in this way do not require any maintenance with regard to replacement, e.g. an otherwise used battery primary cell because these batteries are completely passive during storage and therefore allow long storage times.
- the sequence of the previously programmed igniter function is activated by activating the battery, i.e. started by the run-up of the battery voltage during the mechanical-chemical activation by the launch accelerations.
- the activatable batteries used must therefore be designed so that they reliably activate in the entire temperature range even with the smallest propellant charge when fired. On the other hand, they must be subjected to mechanical loads
- Programming coil 12 to transmit energy and programming information through the transmission coil 22 of a scale-external programming device 23 via the magnetic coupling of the two coils and a modulated alternating magnetic field. It is also known to use the energy transmitted in the programming process to supply the scale during the programming process and because after the programming process the
- Energy transmission is interrupted by the programming device 23, the information transmitted during the programming process is stored in a non-volatile manner, for example in an EEPROM in the scale electronics
- the one-way rectification by the diode 14 only the positive half wave of the AC voltage present at the connection point of the components 12, 14, 13 and 18 is loaded, so that the positive half wave at this point practically never exceeds the Zener voltage of the Zener diode 4 plus the forward voltage of the diode 14
- the negative half-waves can assume a voltage amplitude of 50 to 60 V at the output of the coil 12. The energy contained in these half-waves has not been used until now 1, the high-blocking diodes 1 and 18 on again, so through the one-way rectification of the negative half-waves of the output of the coil 12, the supply capacitor 1 for the scale electronics and
- the energy 0.5 Ci Ui 2 is available after the programming for supplying the voltage regulator 17 and the scale electronics 3 and to supply the ignition stage with the energy 0.5 C19 ⁇ 9 2
- the flight phase is then preferably initiated by a switch 5 (which is very simple to design for the blocking phase during programming and the time before the shot) and which connects the inverting switching voltage regulator 17 to the capacitor 1.
- the switch 5 is activated by the generally specially developed, Security device 9 hardened against environmental influences is actuated very securely by an actuating element 10 when the environmental forces typical of a shot occur, so that an unintentional closing of the switch 5 before the actual shot is practically only possible with the tiny probabilities of 10 7 to 10 * which are customary in mechanical security devices. ⁇ Can occur If the scale is not programmed, it is even completely energy-free, which makes it even safer compared to detonators with built-in batteries
- the switch 5 is designed in such a way that it closes after the typical projectile accelerations occur and, for example, remains closed during the entire flight phase due to mechanical locking, there is no need for the electronic latch 11 shown in broken lines in FIG. 1. If this cannot be ensured, then The latch 1 1 ensures that when a voltage occurs at point Z, input X is conductively connected to output Y and remains connected as long as voltage regulator 17 is operating
- the two operating modes, programming / flight, are recognized via the two inputs Up and F of the scale electronics. If voltage is present at U P and there is no voltage at F, switch 5 is still open and the electronics detects programming when Uv occurs and processes it Corresponding programming sequences at Port Up However, if switch 5 is closed, voltage is applied to input F (and no programming sequence at input Up) and the electronics process their programmed flight program
- the switching voltage regulator 17 must have a high degree of efficiency and a very large input voltage range in order to avoid unnecessary energy losses. It is therefore preferably developed especially for these or similar applications and integrated into an ASIC because of the smaller and therefore energy-saving structures
- the storage capacitors 1 and 19 must also, for reasons of small losses, preferably be film or ceramic capacitors with the smallest possible leakage current, since their charging must be available as unchanged as possible even after 10 to 20 minutes after programming in the flight phase
- the supply capacitor 19 for the ignition stage 16 is charged in parallel with the supply capacitor 1 during the programming phase. This arrangement is necessary because the capacitor 1 is discharged while supplying the scale electronics 3 and therefore a sufficient ignition voltage level if the ignition stage 16 is also supplied could not be guaranteed from capacitor 1
- the capacitor 19 Shortly before the ignition stage 16 is ignited by the Zundt ⁇ gger signal at the output T of the scale electronics 3, the capacitor 19 is connected to the ignition stage 16 via the signal S of the scale electronics 3 and a suitable electronic switch 24 and this is only supplied with energy at this late point in time Despite the early charging of the capacitor 19, a high level of overflight of the scale is achieved in the programming phase
- the arrangement according to FIG. 1 has a further advantage.
- the scaling electronics 3 in addition to the programming input Up, also interrogate input F. If the switch is open, ie if the safety device is in the safe position, there is no voltage at F and the programming can be carried out as intended If, however, the switch 5 is closed during the programming process, ie if the safety device is in the armed position, the voltage of the switch 5 becomes
