Title (EN) RADAR LEVEL GAUGE
(FR) JAUGE DE NIVEAU À RADAR
Abstract:
(EN) A radar level gauge for determining a filling level of a product in a tank, comprising a volatile high-speed working memory, a first processing unit connected to the volatile high-speed working memory, the first processing unit having an active mode in which the first processing unit is turned on and accesses the working memory, and an inactive mode where the first processing unit is turned off, wherein the working memory has a memory preserving low power mode during periods when the first processing unit is in inactive mode, and an auxiliary power connection configured to provide power to the volatile high-speed working memory from the power management circuitry during the memory preserving low power mode, wherein the processing circuitry is designed to reduce any leakage currents from the volatile high speed memory to the other parts of the processing circuitry in the memory preserving low power mode.
(FR) L'invention concerne une jauge de niveau à radar pour déterminer un niveau de remplissage d'un produit dans un réservoir, comprenant une mémoire de travail volatile à grande vitesse, une première unité de traitement connectée à la mémoire de travail volatile à grande vitesse, la première unité de traitement ayant un mode actif dans lequel la première unité de traitement est en marche et accède à la mémoire de travail, et un mode inactif dans lequel la première unité de traitement est éteinte, la mémoire de travail ayant un mode basse puissance préservant la mémoire pendant les périodes durant lesquelles la première unité de traitement est en mode inactif, et une connexion d'alimentation auxiliaire configurée pour fournir de l'énergie à la mémoire de travail volatile à grande vitesse à partir des circuits de gestion d'énergie pendant le mode basse puissance préservant la mémoire, le circuit de traitement étant conçu pour réduire tout courant de fuite entre la mémoire volatile à grande vitesse et les autres parties du circuit de traitement dans le mode basse puissance préservant la mémoire.
