- known remote control system regardless of the type of transmission Control commands, through which both in the mine and in the released Control device built-in synchronously operating time control devices various parameters of the command transmission can be changed depending on the time.
- This type of backup requires that it takes time to arm the mine passes, which cannot be influenced by the selection by a random generator.
- Such fuse protection especially when used in civilian applications Ignition device is incalculable for planning processes with work progress.
- the object of the present invention is to prevent intrusion and unwanted Trigger to introduce safe radio-controlled ignition device in which the chronological sequence of the commissioning of the radio ignition device until the ignition of the detonators is determinable and traceable.
- the task is solved with the help of Features of the first claim. Using the features of Nineteenth claim, the task is solved according to the process.
- the ignition device for detonators that can be triggered by radio, consists of an igniter and at least one of the igniter spatially Separate trigger unit to which at least one detonator is connected is. Ignitor and trigger unit communicate using radio signals.
- the Trip unit has the following modules, their function later in detail is explained in more detail: energy module, system control, transmitter and receiver unit, first belay device, second belay device and thecruzündch.
- the release unit contains a data carrier on which the for the ignition required information is stored. This disk is not firmly attached to the trip unit and can be removed to it into the igniter and read the data there into a memory.
- the Ignitor therefore contains a reading device for the data of the data carrier.
- Chip cards are preferred as data carriers used. However, other data carriers can also be used which are in the Are able to store data and from which data can be read, for example cards with magnetic stripes or barcodes.
- the release unit and the data carrier assigned to it must be identical Identification marks included. If this is not the case, after reading in the Data from the data carrier into the ignitor when communicating with the Trip unit no identification. So should be tried with a faulty data carrier or with a data carrier with faulty data Triggering the trigger unit is due to the faulty Deny appropriate commands from identifier.
- the Trip unit is activated.
- the igniter as well as the one that can be spatially arranged by it Trip unit can be protected against misuse by an access lock. Only after lifting this access block, for example from a mechanical lock or can consist of an electronic lock that is canceled by entering a code, or even a combination of both, the radio ignition device according to the invention can be made ready for operation become.
- the data carrier can also be used to release the operating option Release removal.
- the time passes First an unlocking time, which can be up to 15 minutes, for example. Tripping is not possible during this time and the safe removal of the Possible from the danger area.
- the data of the data carrier in the ignitor has been read, it is ready to send and receive added. However, communication is only possible after the safety time has expired possible between ignitor and trigger unit.
- triggering units can be controlled with one igniter also several detonators can be assigned. Each trip unit is over the ignitor can be controlled individually and thus also each to a trigger unit connected detonators according to those in the ignitor and in the release unit stored data.
- the user starts a program, where the program monitors itself in a results-oriented manner and if errors are found the trigger prevents.
- the ignition command to the detonators can be made accordingly Method according to the invention only after successive cancellation of predetermined ones Trigger locks take place within security levels.
- To lift one The trigger lock runs within a security level for the preparation of the Ignition required process step. Only when the result of this If the procedural step fulfills a requirement, the next block is lifted possible. The ignition is only ignited when all locks are released possible. If a procedural step cannot be started or a Method step does not lead to a predetermined result, the following one Process step cannot be started.
- An error occurs when triggering a Detonator, for example by transmitting an incorrect code or lie mechanical faults in the ignitor, the trip unit or the connected one
- the process is interrupted immediately. Based on the elapsed time and for example by checking the at the connections of the ignition line to the Ignition voltage is possible to identify the cause of the fault.
- the detonators can be used with the electronics trigger locks are also generated. This makes the detonators more advantageous Way against unwanted tripping, for example by high voltage or RF influence, secured.
- a secured electronic detonator is only by entering a release code in the electronics for the so-called Ready for ignition activated. everyone else, at the entrance to the electronics of the detonators adjacent voltages are ignored.
- the unlocking code thus represents a Release lock and prevents accidental ignition.
- the ignition will from the release unit after releasing by a so-called Ignition code generated. Through each of the release unit and from the electronic detonator accepted code, the ignition is gradually released in the order of energy supply, provision of ignition voltage, unlocking and firing order.

- the process step reached can be used by the user possible bidirectional communication is shown on the display of the trip unit be so that he himself can decide on the release of the release lock and it can be triggered by a radio signal.
- the cancellation can also be done directly, program controlled, run. It is that the ignition wire to the detonators released that was previously short-circuited, for example by a Fuse.
- the resistance of the fuse and the given Charge level of the charge storage are coordinated so that the Fuse is destroyed only after reaching this level, for example by Melting the safety wire.
- the trigger lock cannot canceled and the ignition cable is not released for signal transmission, because, for example, the safety wire does not melt. Furthermore, the Sending and receiving unit not released. So the trip unit is still blocked.
- the user can switch to the second Security level initiate the so-called sharpening by means of a radio command. Sharpening can only take place if the identification mark of the Tripping unit with the identifier that corresponds in the Ignitor was read.
- the sharpening can also be automatic under program control expire. Only with this command the system control and the safety ignition level by closing a relay from the energy module Power supplied. This removes the second trigger lock.
- the Electronic the release unit independently checks whether the safety ignition level is at the output a voltage required for the ignition is maintained. From now on it is possible give the command to fire an igniter. In the event of an error, a Shutdown of the trip unit and with bidirectional communication with a Message to the ignitor.
- the triggering of the individual triggering units takes place, depending on the equipment of the Tripping units and the specification of the user, individually, in groups or in Composite. If an electronic detonator is used, the release unit must do so generate the unlock code and then the ignition code to the detonator to initiate.
