CONTROLLED DETONATION LOGIC CIRCUIT Russian patent published in 2022 - IPC F42D1/04 F42B3/10 F42C15/00 

FIELD: explosive technology.

SUBSTANCE: invention relates to explosive technology - detonation transmitters for explosive devices (ED), namely to controlled circuits for the transmission and initiation of detonation with blocking properties, used in mining and construction work. Controlled detonation logic circuit contains two main sections of equal length, connecting the first and second inputs of the circuit with the logic element "AND", and a disconnected section of smaller length, connecting the first input with the logic element "AND". An additional switchable section is included in the circuit, connecting the existing switchable section with the second input of the circuit. In this case, the main section of the circuit, connecting the first input of the circuit with the logical element "AND", contains an additional logical element "AND". Logic elements "AND" can be connected to the common output of the circuit, while one of the connections contains a delay line. The circuit inputs can be combined by an additional section containing a common input, while this option can also have a common output when one of the connections suitable for it contains a delay line.

EFFECT: expanding the functionality of the controlled detonation logic circuit due to the possibility of implementing two different modes of its active operation while maintaining the blocking mode in the initial passive state, which excludes the detonation of the main explosive charge or explosive composition in the ED from emergency non-simultaneous initiation of inputs from adjacent external detonators, for example, with a bullet, fragmentation, shock wave or electrical impact on them.
