Definitions
- the invention relates to a method for exchanging data between a device for programming and triggering electronic detonators and the detonators according to the preamble of the first claim.
- This mining process involves blasting operations in which explosive charges placed in many boreholes are detonated one after the other according to a specific schedule.
- a method for controlling detonators and a so-called coded structure for controlling detonation are known, for example, from EP 0 588 685 B1.
- the electronic detonators of the explosive charges form an ignition system.
- the electronic detonators are connected together via a so-called bus line to a device for programming and triggering.
- the electronic detonators are controlled via this bus line and receive electrical energy, which they capacitively store. If the capacity of a detonator is charged, it is able to operate independently with the help of the energy stored in its capacitor. The stored energy ensures the function for ignition and for communication between the igniter and the device for programming and triggering the igniter.
- each individual detonator has an address assigned to it, which consists of a multi-digit digital code.
- the delay time with which the point in time at which the respective detonator is triggered is coded in the form
- the signals can go out There are polarity changes of a predetermined voltage at a predetermined level.
- the delay time is coupled with an address code, so that each detonator charges only the delay time assigned to it based on the address code. After the detonator has received the data assigned to it, it must send a response so that it can be determined that the delay time has been properly received and stored by the detonator electronics.
- the signals in the data generally consist of polarity changes in a specific time sequence and in a specific number. These polarity changes are distorted due to the capacitive resistors, so that a clear transmission of the signals is not always guaranteed.
- the capacitive resistances the data transmission rates per unit of time are low and the programming of a detonator, which takes place in the dialog of the electronics of the detonator with the device for programming and triggering the detonator, is time-consuming and not always trouble-free.
- Ignition circuit with a predetermined duration applied a DC voltage that is higher than the voltage of the signals with which the data is generated, which the igniter transmits in response.
- the increased voltage is below a critical voltage for triggering an igniter.
- the detonators are typically designed to withstand voltage, i.e. H. are not triggered, which is at a certain level above the nominal voltage, which is intended to generate the signals for communication with the detonators. According to the invention, the intended tolerance range is not exhausted in order to avoid any risk.
- the level of the voltage is chosen so that the capacities of the other detonators are charged to such a level within a very short time that a weakening of the voltage with which the signals of the detonator's response are generated is avoided.
- the voltage is lowered and the signals of the data which the detonator transmits in response are generated with a lower voltage.
- all other detonators are charged to such a high level that they no longer represent capacitive resistors and communication is therefore possible at a very high data transmission rate per unit of time.
- the voltage in the ignition circuit is increased to such a value over such a duration that during the subsequent response of one igniter no capacities of the other igniters have to be charged due to charge losses.
- the level of the capacitive and ohmic resistances within the ignition circuit depend on the number of connected electronic detonators.
- the capacitive resistance it is possible for the capacitive resistance to be determined and, depending on its size, the DC voltage which is at least required to charge the capacitors to be determined.
- the voltage drop caused by the ohmic resistors can be compensated.
- the increase in the DC voltage can thus be individual to the respective Use case to be coordinated. It also ensures that the voltage does not exceed a critical value that triggers an igniter.
- a bus line 3 symbolized by two wiring harnesses 3a and 3b, leads from the device 2 for programming and triggering the detonators to the detonators 4a, 4b and 4c.
- the charges 5a, 5b and 5c are assigned to the detonators 4a, 4b and 4c.
- the three electronic detonators shown represent any number of detonators that are connected to bus line 3 in accordance with the respective specification.
- This bus line 3 enables bidirectional data transmission, that is, from the device 2 for programming and triggering the detonators to the detonators and from the electronics of the detonators to the device 2 back.
- the length of the bus line 3 and the electronics of the detonators cause a voltage drop within the ignition circuit 1, which is symbolized by the ohmic resistors labeled 7a, 7b and 7c.
- 8a, 8b and 8c are capacitors which are intended to represent the energy stores of the respective detonators. The energy stored in them enables communication between the detonators 4a to 4c and the device 2 for programming and triggering the detonators. The stored energy is also used to trigger the detonators.
- Each of the detonators 4a to 4c has an address stored in its electronic circuit 6a to 6c. This address consists of a coded signal, a signal with a predetermined number of polarity changes in a predetermined time. The data is transmitted with a voltage of a certain level, which is supplied by the voltage source 9.
- the detonator addressed responds when it has received the data properly with the delay time provided for it.
- the voltage of the voltage source 9 is increased so far in a predetermined time before the detonator responds that the capacities of the other detonators are charged to such an extent that at the time of the detonator's response no capacities of the other detonators due to charge losses of the capacities need to be charged.
- the remaining detonators therefore do not represent capacitive resistors for the responding detonator, which impair the quality of the response signals.
- the answer of the responding detonator is at a lower voltage level than the previously increased voltage level.
- the signals from the detonator are transmitted without interference to the device 2 for programming and triggering the detonators. If the responding detonator has transmitted its answer and a subsequent detonator is to respond, the voltage in the ignition circuit is also increased before its reply, so that the subsequent answer does not obstruct the signal transmission by capacitive resistors.
- the capacitive resistance and the voltage drop in Ignition circuit 1 can be determined. These values are transmitted via line 13 to device 2 for programming and triggering the detonators. To overcome the capacitive resistance and to charge the Capacitors then have a higher voltage at the ignition circuit 1 than is required to generate the signals of the data which the igniter transmits as a response.
