ELECTRONIC TIME CONTROL OF DETONATOR

摘要

An electronic time fuse having the induction and manual setting functions having : a one chip microcomputer(5) reading a data through a rectifying circuit(1) appling the power and a charging condenser(2) charging the power if continuous transmission signals are transmitted from a time charging system(A) through coils(L1,L2) to a electronic time fuse(B); a memory(8) storing the data; a Tr switch(6) transmitting the signals outputted from the one chip microcomputer(5) to the time charging system(A); a setting switch(9) determining the data to be stored and connected to the one chip microcomputer(5); a battery(12) appling the power in manual setting by an operating switch(11) and connected to the one chip microcomputer(5) and the memory(8); a display(7) displaying the data and connected to the one chip microcomputer(5) to effect manual setting; an ignition circuit(10) generating an ignition signal to operate the fuse; is disclosed. Thereby, it is possible to effect manual setting by using the setting switch attached to the fuse and to effect induction setting by using the time charging system.
