Abstract

"SISTEMA DE INICIAçãO REMOTO CONTROLADO POR DIVERSIDADE DE FREQuêNCIA". Um sistema de detonação (10) compreende uma ligação sem fio (18) entre um controlador de detonação (12) e uma pluralidade de detonadores eletrónicos (22.1 até 22.n). Cada detonador compreende um respectivo iniciador eletrónico (24) e uma carga explosiva (26). Dispositivos de armazenagem de carga dos iniciadores são carregadas por meio de um portador, de um primeiro sinal que tem uma primeira freq³ência (f~ 1~) na ordem de 400 MHz até 500 MHz e que é radiodifundido por meio do controlador de detonação. Cada iniciador ainda compreende circuitos lógicos acionados por um sinal de relógio que é derivado do primeiro sinal e que tem uma freq³ência de relógio de cerca de 4 kHz, que é substancialmente menor do que a primeira freq³ência.
