METHOD OF CHECK OF ELECTRIC FUZE-PUNCHER WITH INDUCTIVE CONTROL CIRCUIT Russian patent published in 1997 - IPC

FIELD: blasting operations, instruments for setting the electric fuzes with an inductive control circuit. SUBSTANCE: the method consists in a successive check-up of the technical condition of each transmitting channel of the inductive control circuit at its readiness to transmit the command for actuation of the electric fuze power source, check-up of transmission of data an the flight time of ammunition with the electric fuze, as well as in successive check-up of the technical condition of the emergency indicators and each transmitting channel of the electric fuze inductive control circuit at a non-operative check-up and absence of readiness of the inductive control circuit to transmission. At a non-operative check-up and absence of readiness of the electric fuze inductive control circuit to transmission the technical condition of the communication line between the electric fuze- pusher and ballistic computer can be checked additionally. The check-up of the technical condition of the transmitting channel of the inductive control circuit consists in transmission of the preset number of pulses and counting of their quantity in the transmitting channel of the inductive control circuit, the preset number of pulses contains information on the flight time of ammunition with the electric fuze even in one of the transmitting channels of the inductive control circuit. EFFECT: facilitated procedure. 4 cl, 1 dwg
