Abstract

"INSTALAçãO DE TIROS PIROTéCNICOS PROGRAMáVEIS". A presente invenção refere-se à instalação de tiros pirotécnicos programáveis, comportando uma unidade (8) de programação e de comando dos tiros, uma linha de programação e de comando comportando dois fios (6a, 6b) condutores e uma pluralidade de detonadores eletrónicos (12), montados em paralelo sobre essa linha bifilar, caracterizada pelo fato da unidade de programação (8) comportar meios (9, 10) de estabelecimento de uma tensão contínua entre os dois fios (6a, 6b), meios (9, 1 0) para gerar impulsos dessa tensão, a fim de formar sinais codificados, e meios (11, 9) de leitura das variações de corrente existentes sobre a linha bifilar e pelo fato de cada detonador comportar um módulo eletrónico (12), possuindo meios (14, 17), aptos a gerarem, em resposta a alguns dos sinais codificados da unidade (8) de programação, impulsos de corrente na linha bifilar (6a, 6b) para formar sinais codificados."INSTALLATION OF PROGRAMMABLE PYROTECHIC SHOTS". The present invention relates to the installation of programmable pyrotechnic shots comprising a shooting control and programming unit (8), a programming and control line comprising two conductor wires (6a, 6b) and a plurality of electronic detonators ( 12), mounted in parallel on this two-line line, characterized in that the programming unit (8) has means (9, 10) for establishing a continuous voltage between the two wires (6a, 6b), means (9, 10). ) to generate pulses of that voltage to form coded signals, and means (11, 9) for reading current variations on the bifilar line and for each detonator having an electronic module (12) having means (14 17) capable of generating, in response to some of the coded signals of the programming unit (8), current pulses in the bifilar line (6a, 6b) to form coded signals.
