Abstract

Processo e Dispositivo para Detecção de Materiais Magnéticos em Sistemas Anti-Furtos de Tecnologia Eletromagnética Processo e dispositivo com respectivo circuito eletrónico, destinado à detecção de qualquer material magnético que se desloque nas proximidades das antenas/sensores utilizadas em sistemas anti-furtos de tecnologia eletromagnética. O referido processo e dispositivo pode ser acoplado tanto interna quanto externamente a estes sistemas, diminuindo a atual vulnerabilidade à burla destes sistemas. Os atuais sistemas anti-furtos de tecnologia eletromagnética em virtude do método de burla notório, são vulneráveis por não apresentarem uma detecção de materiais magnéticos. Os presentes processo inventivo e o dispositivo inventivo suprimem tal deficiência por filtrarem e processarem corretamente o sinal DC gerado pelo deslocamento de um material magnético nas proximidades de uma ou mais antena/sensor destes sistemas. A detecção é obtida a partir de um sinal diferencial existente na etapa receptora das antenas/sensores (6) do referido sistema, que é enviado à unidade de controle (7) deste mesmo sistema, onde é acoplado um dispositivo referente à presente invenção caracterizado por: um filtro de "enésima" ordem (1), um buffer ou circuito isolador (2), um circuito de ajuste de sensibilidade ou ganho (3), uma lógica de controle (4) e um módulo de alarme (5). Este dispositivo realiza a detecção do material magnético.
