Title
(EN) ENERGY-EFFICIENT SYSTEM FOR DISTANT MEASUREMENT OF ANALOGUE SIGNALS
(FR) SYSTÈME ÉCONOME EN ÉNERGIE DESTINÉ À LA MESURE À DISTANCE DE SIGNAUX ANALOGIQUES
Abstract
(EN)
The invention discloses an energy-efficient system for, preferably wireless, measurement of analogue signals comprising one or more measuring units (10). Each measuring unit (10) comprises measuring probe (11)' which signal is processed by the modulator (12). All measuring units (10) have identical modulators (12) selected from the Time Encoding Machine (TEM) family consisting of: Asynchronous Sigma Delta Modulator (ASDM), Integrate And Fire Modulator (IAFM) and Integral Pulse Frequency Modulator (IPFM). Signal from modulator (12) is processed by a delay circuit (13) from which is optionally fed back to the modulator (12). Signal from the delay circuit (13) and modulator (12) is used to trigger UWB pulse generator (14), from where is optionally amplified via amplifier (15) and transmitted via transmission line or antenna (16). The delay circuit (13) uniquely characterizes measuring unit (10) and enables receiving unit (20) to separate received signals from plurality of measuring units (10) signals sent in unsynchronized manner. The invention is useful for long term acquisition of analog signals, especially time varying signals such as biological signals, i.e. ECG or EEG.

L'invention se rapporte à un système économe en énergie destiné à la mesure, de préférence sans fil, de signaux analogiques, et comprenant une ou plusieurs unités de mesure (10). Chaque unité de mesure (10) comprend une sonde de mesure (11) dont le signal est traité par un modulateur (12). Toutes les unités de mesure (10) ont des modulateurs (12) identiques sélectionnés dans la famille des machines de codage temporel (TEM), constituée par : un modulateur sigma-delta asynchrone (ASDM), un modulateur "Integrate And Fire" (IAFM) et un modulateur d'impulsions en fréquence intégrales (IPFM). Le signal en provenance du modulateur (12) est traité par un circuit à retard (13) qui le retransmet éventuellement au modulateur (12). Le signal provenant du circuit à retard (13) et du modulateur (12) sert à déclencher un générateur d'impulsions UWB (14), où il est éventuellement amplifié par un amplificateur (15) et transmis par une ligne de transmission ou une antenne (16). Le circuit à retard (13) caractérise de manière unique l'unité de mesure (10) et permet à une unité de réception (20) de séparer des signaux reçus d'une pluralité de signaux d'unités de mesure (10) envoyés de façon non synchronisée. Cette invention est utile à l'acquisition à long terme de signaux analogiques, en particulier de signaux variant avec le temps tels que des signaux biologiques relatifs à l'ECG ou l'EEG.
