Abstract

resumo “detector de vazamento de gás ultrassônico” um detector de vazamento de gás ultrassônico é configurado para discriminar o ultrassom gerado por um vazamento de gás pressurizado para a atmosfera a partir de um ultrassom de falso alarme. uma realização exemplificativa inclui um sistema sensor para detectar energia ultrassônica e proporcionar sinais de sensor e um controlador eletrônico responsivo aos sinais de sensor. em uma realização exemplificativa, o controlador eletrônico é configurado para proporcionar uma função de comparador de limite para comparar um valor do sinal de sensor representativo da energia ultrassônica detectada com um valor limite de detecção de gás, e uma função de rede neural artificial (rna) para processar os sinais derivados dos sinais de sensor digital e aplicar coeficientes de rede neural artificial (rna) configurados para discriminar fontes de falso alarme a partir de vazamentos de gás. uma função de saída gera saídas do detector dependendo da saída do comparador de limite e da saída da rede neural artificial (rna). o sistema sensor pode incluir um sensor de banda larga e um ou mais sensores de banda estreita. ?? ?? ?? ?? 1/1
