À l’ère de l’IoT (Internet des objets), le nombre et la variété des appareils matériels ne cessent d’augmenter. Plusieurs appareils IoT sont utilisés dans les équipements d’infrastructure. La manière de maintenir de tels appareils IoT est une préoccupation majeure. Mesure de capacité est l'un des moyens puissants de détecter les états anormaux dans la structure des périphériques matériels. En particulier, mesurer la capacité pendant que le dispositif matériel est en fonctionnement constitue un défi majeur, mais aucune recherche de ce type n'a été proposée jusqu'à présent. Cet article propose un appareil de mesure de capacité qui mesure la capacité du dispositif en fonctionnement. Nous combinons d'abord le signal de tension alternative (courant alternatif) avec le signal de tension d'alimentation continue (courant continu) et générons le signal fluctuant. Nous fournissons le signal fluctuant à l'appareil cible au lieu de fournir la tension d'alimentation CC. En filtrant efficacement le courant observé dans le dispositif cible, le courant filtré peut être proportionnel à la valeur de la capacité et nous pouvons ainsi mesurer la capacité du dispositif cible même lorsqu'il est en fonctionnement. Nous avons implémenté le dispositif de mesure de capacité proposé sur le circuit imprimé de taille 95 mm × 70 mm et évalué la consommation d'énergie et la précision de la mesure de capacité. Les résultats expérimentaux démontrent que la consommation d'énergie du dispositif de mesure de capacité proposé est réduite de 65 % en mode faible consommation par rapport au mode de mesure et que le dispositif proposé a mesuré avec succès la capacité avec une résolution de 0.002 μF.

Abstract: In IoT (Internet-of-Things) era, the number and variety of hardware devices becomes continuously increasing. Several IoT devices are utilized at infrastructure equipments. How to maintain such IoT devices is a serious concern. Capacitance measurement is one of the powerful ways to detect anomalous states in the structure of the hardware devices. Particularly, measuring capacitance while the hardware device is running is a major challenge but no such researches proposed so far. This paper proposes a capacitance measuring device which measures device capacitance in operation. We firstly combine the AC (alternating current) voltage signal with the DC (direct current) supply voltage signal and generates the fluctuating signal. We supply the fluctuating signal to the target device instead of supplying the DC supply voltage. By effectively filtering the observed current in the target device, the filtered current can be proportional to the capacitance value and thus we can measure the target device capacitance even when it is running. We have implemented the proposed capacitance measuring device on the printed wiring board with the size of 95mm × 70mm and evaluated power consumption and accuracy of the capacitance measurement. The experimental results demonstrate that power consumption of the proposed capacitance measuring device is reduced by 65% in low-power mode from measuring mode and proposed device successfully measured capacitance in 0.002μF resolution.
