Avionics systems, comprise a controller and at least one peripheral device connected to the line provides both power and data exchange

摘要

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.
