Abstract

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.
