FIELD: inflammation of explosives. ^ SUBSTANCE: the system of electronic detonators has a control unit, a great number of electronic detonators and a busbar that connects the detonators to the control unit. Each electronic detonator has a number of flag indicators, which may take any of the two probable values, each flag indicator shows the prestate of the respective detonators. The flag indicators may be read off by the control unit by means of packs of digital data, and the control unit by means of these flag indicators is made for checking the state of the electronic detonator and control its functioning. At reading off of the flag indicator the electronic detonators give answers in the form of analog response pulses to the busbar. The system of detonators has a portable receiver of messages, which on the basis of the mentioned flag indicators, receives messages concerning the state of connection of the detonators. ^ EFFECT: enhanced efficiency. ^ 28 cl, 6 dwg |
