DETONATING DEVICE Russian patent published in 2003 - IPC

FIELD: means of initiation of explosive charges with a programmed time delay. SUBSTANCE: the detonating device has a body and a charge of a pressed high explosive of a bulk density, charge of initiating compound and an inflammation unit made in the form of a metal spiral, connected to an electronic module connected to two-wire of charging control and comprising a microprocessor having an individual identification number, accumulating capacitor, connected to which a network of the series-connected inflammation un and the blasting key all placed in the body in succession. Connected to the charge-control line is a rectifier-doubler made on a stabilizer diode, diode and protective high-voltage capacitor. Connected to the accumulating capacitor is a step-down stabilizer, whose output is connected to the supply input of the microprocessor. The input of the blasting control key is connected to the first signal output of the microprocessor. Connected to the accumulating capacitor is also a network of the series-connected charging resistor, measuring key and measuring capacitor, the common point of connection of the measuring key and measuring capacitor is connected to the second signal output of the microprocessor. The control input of the measuring key is connected to the supply circuit of the microprocessor, the two-directional level matcher is connected by one input=output to the third signal output of the microprocessor, by the other input-output - via the protective capacitor to the charge-control line. EFFECT: enhanced precision of the time of operation, provided remote checking of the device, enhanced noise immunity. 2 dwg
