Programmable pyrotechnical firing installation comprising a programming and
firing
control unit (8), a programming and control line comprising two conductor
wires (6a,
6b) and a plurality of electronic detonators (4) mounted in parallel on this
two-wire
line, characterised in that the programming unit (8) comprises means (9, 10)
for
establishing a continuous voltage between the two wires (6a, 6b), means (9,
10) for
producing pulses of this voltage so as to form coded signals, and means (11,
9) for
reading the current variations existing on the two-wire line, wherein every
detonator
comprises an electronic module (12) that has means (14, 17) suitable for
producing, in
response to certain of the coded signals of the programming unit (8), current
pulses in
the two-wire line (6a, 6b) for forming coded signals.
Installation de tirs pyrotechniques programmables comportant une unité (8) de programmation et de commande des tirs, une ligne de programmation et de commande comportant deux fils (6a, 6b) conducteurs et une pluralité de détonateurs électroniques (12) montés en parallèle sur cette ligne bifilaire, caractérisée en ce que l'unité de programmation (8) comporte des moyens (9, 10) d'établissement d'une tension continue entre les deux fils (6a, 6b), des moyens (9, 10) pour engendrer des impulsions de cette tension afin de former des signaux codés, et des moyens (11, 9) de lecture des variations de courant existant sur la ligne bifilaire tandis que chaque détonateur comporte un module électronique (12) possédant des moyens (14, 17) aptes à engendrer, en réponse à certains des signaux codés de l'unité (8) de programmation, des impulsions de courant dans la ligne bifilaire (6a, 6b) pour former des signaux codés.
