Title
(EN) ENERGY-EFFICIENT SYSTEM FOR DISTANT MEASUREMENT OF ANALOGUE SIGNALS
(FR) SYSTÈME EFFICACE EN ÉNERGIE POUR MESURE DISTANTE DE SIGNAUX ANALOGIQUES
Abstract
(EN)
The invention discloses an energy-efficient system for wireless measurement comprising one or more measuring units (10). Each measuring unit (10) comprises measuring probe (11), an asynchronous sigma delta modulator (12), a delay circuit (13), ultra wide band pulse generator (14) transmission line (15) being preferably, antenna and a power supply (6). Said asynchronous sigma delta modulator (12) converts an analog signal received by the corresponding measuring probe (11) into digital pulsed signal. The signal formed by asynchronous sigma delta modulator (12) is delayed in a delay circuit (13) for the fraction of time that is unique for the said measuring unit (10) identifying uniquely the analog input received by the measuring probe (11). Signal formed by asynchronous sigma delta modulator (12) and the signal from the delay circuit (13) trigger corresponding ultra wide band pulse generator (14) by their pulse edges, resulting with two ultra wide band pulses per one asynchronous sigma delta modulator (12) signal edge. The invention is very useful for long term acquisition of analog signals, especially time varying signals.

L'invention porte sur un système efficace en énergie pour mesure sans fil, comprenant une ou plusieurs unités de mesure (10). Chaque unité de mesure (10) comprend une sonde de mesure (11), un modulateur sigma-delta asynchrone (ASDM) (12), un circuit à retard (13), un générateur d'impulsions à bande ultra-large (UwbG) (14), une ligne de transmission (15) qui est de préférence une antenne, et une alimentation électrique (1). Ledit modulateur sigma-delta asynchrone (12) convertit un signal analogique reçu par la sonde de mesure correspondante (11) en un signal impulsionnel numérique. Le signal formé par le modulateur sigma-delta asynchrone (12) est retardé dans le circuit à retard (13) pendant la fraction de temps qui est unique pour ladite unité de mesure (10) identifiant d'une manière unique l'entrée analogique reçue par la sonde de mesure (11). Le signal formé par le modulateur sigma-delta asynchrone (12) et le signal provenant du circuit à retard (13) déclenchent le générateur d'impulsions à bande ultra-large correspondant (14) par leurs flancs d'impulsion, entraînant deux impulsions à bande ultra-large par flanc de signal du modulateur sigma-delta asynchrone (12). L'invention est très utile pour l'acquisition à long terme de signaux analogiques, en particulier des signaux temporellement variables.
