Title
(EN) REMOTELY POWERED SENSOR DETECTION PLATFORM
(FR) PLATEFORME DE DÉTECTION DE CAPTEUR ALIMENTÉE À DISTANCE
Abstract
(EN)
A sensor platform (5) is powered remotely through electromagnetic RF energy (12), When the platform (5) is illuminated with electromagnetic RF energy (12) at a specific frequency (fo), the platform (5) develops sufficient power by using a rectenna (15, 62) to drive onboard components (20, 30, 40, 50) such as a tone generator module (40) and a sensor module (20). The tone generator module (40) on the platform (5) produces a dual- tone, amplitude modulated, third harmonic (3fo) of the incoming RF illuminating frequency and subsequently re-transmits the third harmonic (3fo) to a remote receiver. The remote receiver demodulates the third harmonic (3fo) to recover the original tones. Each tone represents a particular state of the sensor module. The sensor platform (5) can be advantageously used to inspect shipping containers.
(FR)
La présente invention porte sur une plateforme de capteur (5) qui est alimentée à distance par une énergie radiofréquence (RF) électromagnétique (12). Lorsque la plateforme (5) est éclairée par une énergie RF électromagnétique (12) à une fréquence particulière (fo), la plateforme (5) développe une énergie suffisante à l'aide d'une antenne redresseuse (15, 62) pour commander des composants à bord (20, 30, 40, 50), tels qu'un modulateur de générateur de tonalité (40) et un module de capteur (20). Le module de générateur de tonalité (40) sur la plateforme (5) produit une troisième harmonique, modulée en amplitude, à double tonalité (3fo) de la fréquence d'éclairage RF arrivant et réémet subséquemment la troisième harmonique (3fo) vers un récepteur à distance. Le récepteur à distance démodule la troisième harmonique (3fo) pour récupérer les tonalités originales. Chaque tonalité représente un état particulier du module de capteur. La plateforme de capteur (5) peut être utilisée avantageusement pour inspecter des conteneurs d'expédition.
