Abstract

<B>SISTEMA SENSOR DE EMISSõES REMOTAS COM DETECçãO DE NO~x~ MELHORADA<D> é propiciado um sistema de percepção remota de descarga com capacidade de detecção de NO~x~. Primeiro, é realizada uma leitura da concentração de NO~x~ ambiente imediatamente antes de cada veículo atravessar o sistema. Esta medição leva em conta qualquer concentração de NO~x~ ambiente que possa retardar-se da exaustão de um veículo anterior. Em seguida, o sistema realiza uma leitura de feixe obstruído quando o veículo está localizado na trajetória do feixe. Esta leitura leva em conta qualquer ruído ambiente ou do sistema que possa existir. Finalmente, o sistema realiza uma leitura da coluna de fumaça de exaustão quando o feixe atravessa a coluna de fumaça. Um processador determina a porção da leitura devida à coluna de fumaça de exaustão mediante subtração das leituras ambiente e de feixe obstruído da leitura da coluna de fumaça de exaustão. Como resultado, é propiciada uma leitura da concentração da exaustão mais precisa. Adicionalmente, o sistema pode processar leituras de coluna de fumaça de exaustão apenas em uma faixa de comprimentos de onda predeterminados associados ao espectro de absorção de NO~x~ conhecido de modo que possam ser eliminados pontos de dados para os quais não existe absorção significativa de NO~x~. Portanto, são minimizados quaisquer ruídos ou outras interferências nos comprimentos de onda não-absorventes. Alterações na intensidade da radiação são também compensadas mediante subtração de uma intensidade de linha de base de cada sinal.
