DETONATING DEVICE Russian patent published in 2000 - IPC

FIELD: means of initiation of explosive charges with a preset time delay. SUBSTANCE: in the known detonating device containing arranged in succession in the casing: a compacted detonating explosive charge; a detonating explosive charge with bulk density; an initiating explosive charge and an ignition assembly, the latter is made in the form of a metal spiral connected to an electronic module consisting of a detonating unit connected to a two-wire line shunted by protective diodes D₁ and D₂ from the control center. Connected to the first storage capacitor C₁ that is connected to the first input of microprocessor with a crystal oscillator. Connected to the second output of the detonating unit is the second storage capacitor C₂, connected to the series-connected ignition assembly and key K₁, whose point of connection via divider R₁, R₂ is connected to input 3 of the microprocessor, additionally connected to capacitor C₂ is the second key K₂, and the control inputs of both keys are connected to the first and second inputs of the microprocessor, the microprocessor has an individual identification number programmed at manufacture. EFFECT: explosion precise in time and remote check-up of detonator serviceability. 2 dwg
