Definitions

  • the invention relates to a method for exchanging data between a Device for programming and triggering electronic detonators and the Ignitors according to the preamble of the first claim.
  • a method for controlling detonators and a so-called coded Structure for controlling the blasting are, for example, from EP 0 588 685 B1 known.
  • the electronic detonators of the explosive charges form an ignition system.
  • the electronic detonators are common across a so-called bus line with a Device connected for programming and triggering. About this bus line
  • the electronic detonators are activated and receive electrical energy is stored capacitively by them. is the capacity of a detonator charged, so he is able to use the energy stored in his capacitor to stay in operation independently. With the stored energy, the function becomes Ignition and communication between the detonator and the device for Programming and triggering of detonators ensured.
  • each individual detonator has an address assigned to it, which consists of one multi-digit digital code.
  • the delay time with which the time is determined at which the respective detonator is triggered, is encoded in the form Pass signals to each individual detonator.
  • the signals can be off Polarity change of a given height given voltage consist.
  • the delay time is coupled with an address code, so that each detonator due to the address code only its associated delay time invites. After the detonator has received the data assigned to him, he must send a reply, so that it can be established that the Delay time received properly from the electronics of the detonator and was saved.
  • the increased voltage is below a critical voltage to trigger a detonator.
  • the detonators are usually designed so that they are resistant to stress, d. H. not be triggered in one certain height above the rated voltage, which is used to generate the signals to Communication with the detonators is provided. According to the invention of the provided tolerance range but not exhausted to any risk avoid.
  • the height of the voltage is chosen so that within a very short time charging the capacity of the remaining detonators on such Level is done that a weakening of the voltage is avoided with which the Signals of the response of the detonator are generated.
  • the voltage is lowered and the Signals of the data which the fuze transmits in response are sent with a lower voltage generated.
  • all other detonators are at such a high level charged that they no longer represent capacitive resistances and thus one Communication with a very high transmission rate of the data per unit time is possible.
  • the voltage in the ignition circuit is on such a duration to one increases such that during the subsequent response of a detonator no Capacities of the remaining detonators are charged due to charge losses have to.
  • the height of the capacitive and ohmic resistances within the ignition circuit are depending on the number of connected electronic detonators.
  • the capacitive Resistance is determined and depending on its size to charge the Capacities at least required DC voltage is determined.
  • the increase in the DC voltage can thus individually to the respective Use case to be coordinated. In addition, this ensures that the Voltage does not exceed a critical value that triggers a detonator leads.
  • the equivalent circuit of a firing circuit is designated.
  • a bus line 3 symbolized by two strands 3a and 3b, to the detonators 4a, 4b and 4c.
  • the detonators 4a, 4b and 4c are associated with the respective charges to be ignited 5a, 5b and 5c.
  • the three illustrated electronic detonators are representative of any Number of detonators, which correspond to the respective specification on the bus line 3 are connected.
  • This bus line 3 allows a bidirectional Data transmission, that is, from the device 2 for programming and Triggering the detonators to the detonators and from the electronics of the detonator to Facility 2 back.
  • the length of the bus line 3 and the electronics of the detonators cause one Voltage drop within the ignition circuit 1, which by the 7a, 7b and 7c designated ohmic resistors is symbolized.
  • 8a, 8b and 8c are Designates capacitors, which are the energy storage of the respective detonator should represent. The energy stored in them enables communication between the detonators 4a to 4c and the device 2 for programming and Trigger the detonator. In addition, the stored energy is used to trigger the Detonators.
  • Each of the detonators 4a to 4c has one in its electronic circuit 6a to 6c stored address. This address consists of a coded signal, a signal having a predetermined number of Polarity changes in a given time. The transmission of the data takes place with a voltage at a certain level, supplied by the voltage source 9 becomes.
  • the remaining detonators for the answering detonator are none Capacitive resistors that affect the quality of the response signals.
  • the response of the responding detonator is at a lower one Voltage level than the previously increased voltage level. From the above Due to a trouble-free transmission of the signals of the detonator to the Device 2 for programming and triggering the detonators. If the answering one Igniter has sent his answer and a subsequent detonator is to answer, is also increased before his response, the voltage in the ignition circuit, so that at the subsequent response no obstruction of the signal transmission by capacitive Resistors occurs.
  • the capacitive resistance and the Voltage drop in the ignition circuit 1 can be determined. These values are over the Line 13 of the device 2 for programming and triggering the detonator transmitted. To overcome the capacitive resistance and to charge the Capacities is then over a predeterminable time at the ignition 1 a higher Voltage, as to generate the signals of the data, the detonator in response transmitted, is required.
