Definitions
- the invention relates to an electronic detonator for detonating an explosive charge, the detonator containing a data control part which evaluates data supplied via a connecting line and actuates a switch to trigger the ignition as a function of this data.
- the detonation of the explosives in commercial use is preferably initiated with electronic detonators. When properly used, this is done with special igniters, which are not particularly secured. Ignition is also possible - assuming little physical knowledge - with an appropriate voltage source. After terrorist attacks or explosives, the investigative authorities find it extremely difficult to obtain clear evidence to narrow down the group of perpetrators.
- Electronic detonators are known which contain an energy store and which, in order to initiate the ignition, require a pulse train with a specific structure to be emitted from an ignition machine (EP 0 147 688 A2).
- detonators are known in which a release code is predetermined by the type of chip used. Changing the unlocking code requires changing the chip and inserting a new chip with a different layout. This involves a great deal of effort.
- the ignitors used in this system must be switched on using the key switch. If the key switch is bridged, the safety function is lost and the igniter can be ignited. There is also the possibility that the code can be analyzed and decrypted in identically constructed detonators and is thus available for misuse.
- the invention has for its object to provide an electronic detonator that offers increased security against unauthorized use of the detonator.
- an unlocking code is stored in a non-volatile memory, for example in a serial communication-capable EEPROM.
- a non-volatile memory for example in a serial communication-capable EEPROM.
- different detachment codes can be entered into the respective memory by the manufacturer in the case of igniters which are identically formed during the production phase.
- each detonator could have its own unlock code get that does not occur in any other detonator.
- the igniter can only be ignited if the data supplied by the igniter corresponds to this unlocking code.
- the fact that triggering with simple energy (ignitor or battery) is not possible eliminates a major source of danger.
- the detonator is secured in such a way that it can only be triggered with knowledge of the unlocking code it contains. This largely prevents unauthorized use of the detonator.
- the large number of different unlocking codes that can be entered in identical detonators is advantageous.
- the ignition circuit of the detonator can be interrupted or blocked and the detonator can thus be rendered unusable. This measure ensures that hackers have no way of cracking the unlock code.
- each user can receive their own unlocking code as an access code.
- This user's ignition devices can be set to this unlocking code.
- the igniter can only be activated with a PIN code. If three attempts are made to decrypt the code, the ignitor blocks all functions. Unlocking is only possible from the manufacturer. Finally, there is the possibility of storing the ignition data in a non-volatile memory by pressing a fire button - not recognizable for the user - with details of the date, time and explosive pattern. This data can only be read out by the manufacturer.
- the drawing shows a schematic block diagram of the electronic detonator.
- the igniter can be connected to an igniter (not shown) via a two-wire connecting line AL.
- the connecting line AL leads to the input part ET, which contains the following components: an input protection 1, a signal coupling 2, a rectifier circuit 3 and a voltage supply 4.
- the input protection 1 forms a filter and fuse circuit. It contains an HF fuse and an overload fuse as well as a voltage limiting circuit that only allows low voltages to pass through.
- Input contactor 1 ensures that
- the signal decoupling 2 forms an interface for decoupling the filtered signals and for converting the analog signals into digital signals.
- the rectifier circuit 3 is fed with the analog signals coming from the input protection 1 and uses this to generate a DC voltage of a defined polarity. Ease of use means that the user can connect the detonator in any polarity.
- the DC voltage is supplied to the voltage supply 4, which consists of a 2-stage voltage regulator.
- the voltage supply 4 In the basic state, after switching on, the voltage supply 4 generates a low supply voltage which is not sufficient to ignite the ignition charge or squib connected to the ignition line ZL.
- the electronic components of the detonator are supplied with this low supply voltage, so that in particular the data control part DST is functional. This ensures the operation of the fuse logic.
- the low supply voltage is below the Nofire threshold.
- the supply voltage of the voltage supply 4 is also supplied to the ignition stage ZS.
- a capacitor has the advantage that a voltage-free ignition system is available in the non-connected state. After the unlocking code has been recognized, the capacitor is charged by the higher supply voltage of the voltage supply 4 to a value which is sufficient to ignite the explosive charge.
- the energy store 5 is followed by an electronic switch 6 in the form of a switching transistor, which is controlled by the data control part DST and in conductive state discharges the energy store 5 to the ignition means connected to the ignition line ZL.
- the data control part DST contains a central control unit CPU, which performs all control processes and logical switching functions.
- the digital signals coupled out from the input part ET are counted at an input counter 7 in order to then be evaluated by the CPU.
- the first data protocol to be checked concerns the unlocking code. This is checked for identity. If there is a match, the CPU sends a reset signal to all components of the data control part, a release command to the power supply for setting the high supply voltage, a synchronization command to the input counter 7 for receiving delay time data and a synchronization command to a reference counter 10.
- the data control part DST contains an oscillator 8, which supplies a clock generator 9 for generating the clock frequency.
- the clock frequency is fed to the CPU and further to the reference counter 10, in which the delay times are stored as real time by counting up.
- the delay time data supplied by the ignition device have the effect that the reference counter 10 is counted up to a value predetermined by this data.
- the unlocking code is stored in the memory 11 and an igniter address is stored in the memory 12.
- the detonator address is a value between 0 and N, e.g. 60, depending on the needs of the user.
- the memory 13 contains customer data. The relevant data are entered in the IT information section during the production of the detonator and cannot be changed after final assembly. There are no opportunities for manipulation from the outside.
- the igniter When the igniter (not shown) is switched on, the igniter is supplied with voltage.
- the information part IT transfers the unlocking code contained in the memory 11 and the igniter address contained in the memory 12 to the CPU. This is then ready to receive the data supplied by the ignitor.
- the ignitor first sends out the unlocking code.
- the CPU checks whether this unlock code is identical to the saved unlock code. If identity is present, the supply voltage is increased from the security level (Nofire) to the ignition level (Allfire). The detonator is now in standby mode, in which ignition is possible.
- the delay time is first programmed in standby mode.
- the igniter address is transmitted via the connecting line AL.
- this detonator address matches the detonator address stored in the memory 12, the reference counter 10 is counted up with a subsequent start-stop sequence.
- the start-stop sequence consists of a start signal and a stop signal on the connection line AL.
- the reference counter 10 counts the pulses of the clock generator 9.
- the final value of the reference counter 10 that is finally reached indicates the measure of the delay time that then expires.
- the reference counter 10 is counted down and when the counter reading "0" is reached, the switch 6 is actuated.
- Manufacturing data and customer data are stored in a further memory 13 of the information part IT.
- the production data include production order, lot name, date of manufacture etc.
- the customer data are customer name, order and delivery data.
- the manufacturing and customer data can be read out by the manufacturer if necessary, but are not accessible to the user.
- the detonator address indicates the type of delay of the detonator in question. Following the igniter address, the igniter then delivers the delay time to be assigned to this address. The delay time can therefore be set separately by the user for each detonator address.
- it can be printed on the connecting cable AL or at another location on a plastic injection molded part.
