Abstract

UNA MAQUINA DE PESAJE, POR EJEMPLO UNA MAQUINA DE PESAJE CONVENCIONAL, TIENE CASILLAS DE ESCALA (31.....3M) Y UNA PLURALIDAD DE CASILLAS FALSAS (41.....4N) INSTALADAS EN EL MISMO PISO. LAS CASILLAS DE ESCALA (31.....3M) IMPRIMEN SEÑALES DE PESO ( W1.....WM) CORRESPONDIENTES A LOS PESOS DE LOS OBJETOS QUE HAN SIDO CARGADOS. EL MODO DE VIBRACIONES DEL SUELO SE DETECTA DESDE LAS SEÑALES FALSAS (D1.....DN) PROCEDENTES DE LAS CASILLAS FALSAS (41.....4N). SE DESPLAZAN DESPLAZAMIENTOS VERTICALES DEL SUELO EN LA POSICION DE LAS CASILLAS DE ESCALA, Y SUS EFECTOS SE ELIMINAN DESDE LAS SEÑALES DE PESO. AQUELLAS CASILLA DE ESCALA NO SELECCIONADAS DESPUES DE UN CICLO DE CALCULOS COMBINATORIOS PUEDEN USARSE COMO CASILLAS FALSAS EN EL SIGUIENTE CICLO. LOS EFECTOS DE LAS VIBRACIONES DEL SUELO PUEDEN ELIMINARSE MAS PRECISAMENTE SI LAS DIFERENCIAS EN SENSIBILIDAD ENTRE LAS CASILLAS DEBIDO A LAS CARACTERISTICAS FISICAS DE LAS CELDAS INDIVIDUALES Y/O DEBIDO A QUE LAS CARGAS DIFERENTES SOBRE ELLAS PUEDEN TENERSE EN CUENTA MEDIANTE CALCULO RETROALIMENTADO O MEDIANTE UNA FORMULA. TAMBIEN PUEDE PROVEERSE DE UN DISPOSITIVO DE CONTROL DE MODO QUE LOS EFECTOS DE LAS VIBRACIONES DEL SUELO SEAN IGNORADAS SI ESTAS SON SUFICIENTEMENTE DEBILES.
