Le Indicateur de charge de pelleteuse<\/a>\u00a0est principalement compos\u00e9 d'une partie acquisition du signal et d'une partie traitement du signal et affichage.<\/p>\n\n\n\n

Acquisition du signal<\/strong><\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

1.<\/strong>Installation du capteur<\/strong>: Les capteurs de pression sont les composants essentiels de la partie acquisition des signaux. Ils sont install\u00e9s strat\u00e9giquement pr\u00e8s des composants cl\u00e9s de l'excavateur, tels que le v\u00e9rin de la fl\u00e8che et le v\u00e9rin du bras. C'est \u00e0 ces endroits que se produisent d'importantes variations de pression au cours du processus d'excavation.<\/p>\n\n\n\n

2.<\/strong>Capteurs de pression<\/strong>: Lorsque l'excavateur fonctionne, en particulier pendant la t\u00e2che de creusement, les cylindres supportent des pressions diff\u00e9rentes en fonction du poids du mat\u00e9riau \u00e0 excaver. Les capteurs de pression sont tr\u00e8s sensibles \u00e0 ces variations de pression.<\/p>\n\n\n\n

3.<\/strong>Conversion des signaux<\/strong>: Les capteurs de pression convertissent les variations de pression d\u00e9tect\u00e9es en signaux \u00e9lectriques. La pr\u00e9cision de ces signaux \u00e9lectriques est de la plus haute importance car elle affecte directement la pr\u00e9cision de pesage de l'ensemble du syst\u00e8me.<\/p>\n\n\n\n

Signal <\/strong>Traitement et affichage<\/strong><\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

1.<\/strong>Traitement initial du signal dans la bo\u00eete de jonction<\/strong>: Les signaux \u00e9lectriques \u00e9mis par les capteurs sont g\u00e9n\u00e9ralement faibles et peuvent \u00eatre accompagn\u00e9s de signaux d'interf\u00e9rence. Ils sont d'abord envoy\u00e9s \u00e0 la bo\u00eete de jonction. Dans la bo\u00eete de jonction, une int\u00e9gration et un pr\u00e9traitement pr\u00e9liminaires des signaux sont effectu\u00e9s. Il s'agit principalement de filtrer les signaux parasites afin de garantir la puret\u00e9 et la stabilit\u00e9 des signaux.<\/p>\n\n\n\n

2.<\/strong>Transmission du signal \u00e0 l'instrument d'affichage<\/strong>: Apr\u00e8s le traitement initial dans la bo\u00eete de jonction, les signaux sont transmis \u00e0 l'instrument d'affichage.<\/p>\n\n\n\n

3.<\/strong>Calcul et affichage du poids<\/strong>: L'instrument d'affichage est \u00e9quip\u00e9 d'un microprocesseur. Le microprocesseur utilise des algorithmes pr\u00e9programm\u00e9s pour convertir les signaux \u00e9lectriques re\u00e7us en valeurs de poids correspondantes. Ces valeurs de poids sont ensuite affich\u00e9es de mani\u00e8re claire et intuitive sur l'\u00e9cran de l'instrument. L'op\u00e9rateur peut ainsi contr\u00f4ler le poids des mat\u00e9riaux excav\u00e9s en temps r\u00e9el, ce qui facilite une exploitation et une gestion plus pr\u00e9cises des travaux d'excavation.<\/p>\n\n\n\n
