Communication system and method for an aircraft cargo/freight handling system
First Claim
1. A system for sending a signal between a power source and at least one Power Drive Unit (PDU) of a cargo handling system of an aircraft, comprising:
- said power source provided within said aircraft, andsaid at least one PDU provided within said aircraft,said power source being capable of providing DC power to said at least one PDU via an electrical power line;
said power source further comprising a first Power Line Communication (PLC) node;
said at least one PDU further comprising a second Power Line Communication (PLC) node;
said first PLC node being capable of sending said signal between said first PLC node and said second PLC node via said electrical power line, wherein said at least one PDU comprises;
a motor;
a DC/AC power inverter;
a DC EMI filter; and
an input connector; and
wherein;
said motor is connected to said DC/AC power inverter and said DC/AC power inverter is connected to said DC EMI filter; and
wherein said DC EMI filter is connected to said electrical power line via said input connector,wherein said second PLC node located in said PDU is connected to said electrical power line at said input connector between said electrical power line and said DC EMI filter.
