NETWORK EXPLOSION INSTRUMENT Russian patent published in 2008 - IPC F42D1/55 

FIELD: explosive works.

SUBSTANCE: invention is related to the filed of explosive works, in particular, to electric explosion of charges, and may be used in mining industry, construction and other fields. Network explosion instrument contains microcontroller, deceleration device in the form of thyristor switch, memorising device, external power supply source, voltage transducer, device of instrument control and protection, current sensor, voltage sensor, analog-digital transducer, device of information input and display. Instrument is equipped with switching device and insulation control unit. One inlet of thyristor switch is connected to voltage transducer and via switching device to blasting circuit, and another inlet is connected to microcontroller. Between voltage transducer and thyristor switch current sensor and voltage sensor are serially connected, the outlets of which are connected to inlet of analog-digital transducer, outlet of which is connected to microcontroller inlet, to other inlets of which the following units are connected: device for information input and display, main memory unit, device of instrument control and protection, and unit of insulation control, which is connected to blasting circuit via switching device, to the inlet of which one of microcontroller inputs is connected.

EFFECT: increase of safety and provision of faultness in operation with blasting circuits.
