Consumption prepayment system using a smart card with management operations for opening, closing, and recording throughputs in liquid ducts

Consumption prepayment system using a smart card with management operations for opening, closing, and recording throughputs in liquid ducts.This system allows the complete management of consumption payment of liquids, adjusting the consumption to unit costs, using a smart card with an incorporated manager program. From a prefixed quantity in volume units, as the wear is produced or the equivalent consumption, the quantity available is updated until it is depleted. The system activates the closing of the conduction line in case of depletion of the consumption allowed, the extraction of the card, or the disconnection of the system. The opening of the conduction line is produced in the case of connection, with an inserted card and capacity of the throughput consumption. These operations are possible by measuring and recording throughputs, which the system allows in real time.

Este sistema permite la gestión integral del pago y consumo de fluidos, ajustando el consumo a costes unitarios, mediante una tarjeta inteligente que lleva incorporado un programa gestor. Partiendo de una cantidad prefijada en unidades de volumen, a medida que se produce el gasto o el equivalente consumo, se actualiza la cantidad disponible hasta su agotamiento. El sistema activa el cierre de la línea de conducción en caso de agotamiento del consumo permitido, extracción de la tarjeta o desconexión del sistema. La apertura de la línea de conducción se produce en caso de conexión, con tarjeta introducida y capacidad de consumo de caudal. Estas operaciones son posibles por la medida y el registro de caudales, que el sistema permite en tiempo real.
