SYSTEM OF ELECTRONIC DETONATORS Russian patent published in 2005 - IPC

FIELD: blasting operations.

SUBSTANCE: the electronic detonators are positioned in a system of electronic detonators, the mentioned detonators are coupled to the control unit via a busbar. The blasting command or the test blasting command is send from the control unit to the detonators, which start the reverse time reference of delay that is stored in each detonator, in the point of synchronization that is delayed relative to the indicated command. At completion of the reverse time reference the detonators cause, in case of a blasting command, a blast, and in case of a test blasting command, production of a response in the point, where they would be burst if the blasting command would have been used. The delayed synchronization makes it possible to check and control the detonators after the mentioned command was received. The invention contains also a similar method in the system of a great number of subordinate control units, connected to which are a great number of detonators, and the main control unit, the system is controlled by the commands of the main control unit.

EFFECT: minimized risk of nonoperating detonators and eliminated risk of random blasting.
