Patent

CA 2740034

According to a first aspect the invention relates to a device forming a central controller (C) intended to be linked to a remote peripheral (P1-PN) by way an electrical power line (L), comprising a power transmitter (1) and a low-pass filter (CC_BF) arranged between the power transmitter and the electrical line, as well as means for transmitting/receiving data (3) in baseband and a high-pass filter (CC_HF) arranged between the data transmission/reception means and the electrical line, the electrical line being of the kind mutualized for the transmission of power at low frequency from the central controller to the remote peripheral and for the simultaneous bidirectional transmission of data in baseband at high frequency between the central controller and the remote peripheral. The invention also relates to a remote peripheral (P1-PN) as well as to the system comprising a central control linked to one or more remote peripherals by an electrical line mutualized for the transmission of power and of bidirectional data simultaneously.

L'invention concerne selon un premier aspect à un dispositif formant contrôleur central (C) destiné à être relié à un périphérique distant (P1-P N) par l'intermédiaire d'une ligne électrique de puissance (L), comprenant un émetteur de puissance (1 ) et un filtre passe-bas (C C_BF) agencé entre l'émetteur de puissance et la ligne électrique, ainsi que des moyens d'émission-réception de données (3) en bande de base et un filtre passe-haut (C C_HF) agencé entre les moyens d'émission-réception de données et la ligne électrique, la ligne électrique étant de la sorte mutualisée pour la transmission de puissance en basse fréquence du contrôleur central vers le périphérique distant et pour la transmission bidirectionnelle simultanée de données en bande de base en haute fréquence entre le contrôleur central et le périphérique distant. L'invention concerne également un périphérique distant (P1-P N) ainsi que le système comprenant un contrôleur central relié à un ou plusieurs périphériques distants par une ligne électrique mutualisée pour la transmission de puissance et de données bidirectionnelles en simultané.
