Errors may occur in a detonating system that consists of several detonating circuits when the connection?the logging-on?of detonators is effected to the buses of a logger which in turn is connected to a blaster. Connecting is effected, particularly in opencast-mining operations, under conditions that may lead to damage, not visible at first, in particular to the insulation of the detonators and also of the detonating lines. Errors may occur in the transmission of data, for example as a result of loss or falsification of the signals to be transmitted or as a result of intrusion of signals from an extraneous detonator.In accordance with the invention it is therefore proposed that a log-on manager is installed which is in bidirectional contact with the loggers, with the blaster and with the log-data communicators of the loggers which signal the data pertaining to the detonators to the logger. The log-on manager coordinates the logging of the detonators on to the respective bus as well as the programming of the detonators and checks whether an error-free transmission of data is taking place.

1. A method for connecting detonators to a detonating system comprising several detonating circuits in which a plurality of detonators are connected to respective buses which each start from a logger which is connected to a blaster assigned to all the loggers, by which the detonators are detonated in a predetermined temporal sequence on the basis of a detonation command, wherein a log-on manager is installed which is in bidirectional contact with the loggers, with the blaster and with log-data communicators of the loggers, which signal data pertaining to the detonators to the logger, wherein when logging the detonators on to the buses of the detonating circuits of the detonating system a logger-on, the person who connects with the detonators, announces his presence to the log-on manager, in that the log-on manager recognizes the logger-on from an identification code assigned to him and assigns him to the logger to whose bus the logger-on wishes to connect the detonators, in that the log-on manager checks whether a detonator is being connected and data are being transmitted at the time of reporting, in that, when no data are being transmitted, the logger assigned to the bus for communicating the data pertaining to the detonator to be connected is switched to receiving and wherein when another detonator is already being connected, the log-on manager sends a message to the log-data communicator to the effect that a transmission of data is not possible, in that the connection of the detonator to the assigned logger is only enabled when the transmission of data pertaining to the other detonator has been concluded and in that the data communicated from the detonators form the basis for the temporal sequence of the detonation of the individual detonators.2. A method according to claim 1, wherein the logger-on announces his presence with his identification code, the log-on manager turns directly to the appropriate logger and, when it is not presently occupied by a transmission of data, switches it to receiving in respect of the signals of the log-data communicator assigned to the logger or alternatively in respect of the data pertaining to a detonator announcing its presence itself when logging-on to the bus.3. A method according to claim 1, wherein the logger-on has received the confirmation from the log-on manager that he can connect the detonator to the bus, he implements the connection of the detonator and acknowledges the logging-on by the transmission of the identification code.4. A method according to claim 3, wherein the position of a connected detonator in the detonating system is communicated to the log-on manager.5. A method according to claim 1, wherein two or more loggers-on announce their presence to the log-on manager with a view to connecting detonators, the log-on manager arranges the messages according to the sequence of their input into a wait-loop, optionally indicates a wait-position and enables a log-on operation only when a preceding log-on operation of a detonator has been successfully concluded or the noting of the error message of a non-orderly connection has been confirmed.6. A method according to claim 1 wherein the data that have been communicated in the course of logging on are incomplete or faulty, the logger reports the error to the log-data communicator and the error is signaled at the log-data communicator or is indicated on a display of the log-data communicator.7. A method according to claim 1, wherein a detonator has been successfully logged on to a bus by a logger-on, the logger acknowledges this at the log-data communicator with an acknowledging signal and thereafter the logger-on communicates the successful logging-on to the log-on manager.8. A method according to claim 1, wherein a detonator has been successfully logged on to a bus by a logger-on, the logger reports this directly to the log-on manager and a corresponding signal appears at the log-data communicator.9. A method according to claim 1, wherein a communication of delay times from the blaster to the individual detonators via the loggers is coordinated by the log-on manager, by the blaster and the loggers, in addition to the individual detonators, also having an address allocated to them by the log-on manager for the purpose of individual addressing, in that the transmission of data is regulated by the log-on manager in such a way that at all times only one logger and, via the latter at all times, only one detonator is addressed by the bluster and the remaining loggers are disabled and in that, when the transmission of data from the blaster to the respective logger and from there in each instance to the detonators has been concluded, the logger reports in each instance the orderly reception of the data by the detonators to the log-on manager and in that, after conclusion of the programming of the detonators that are connected to a logger, said logger is switched off by the log-on manager and the following logger is switched to receiving.10. A method according to claim 1, wherein the transmission of signals between the log-on manager and the log-data communicators is effected bidirectionally by means of radio technology.11. A method according to claim 1, wherein the transmission of signals between the log-on manager and the loggers is effected bidirectionally by means of radio technology.12. A method according to claim 1, wherein the transmission of signals between the log-on manager and the blaster is effected bidirectionally by means of radio technology.13. A method according to claim 2, wherein the logger-on has received the confirmation from the log-on manager that he can connect the detonator to the bus, he implements the connection of the detonator and acknowledges the logging-on by the transmission of the identification code.
