Abstract:
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.
