Abstract
A system for transferring electric power and signals via a power line by time-division multiplexing includes a power line, electronic-circuit units, and controllers. The power line includes a first transmission line and a second transmission line. The first transmission line is connected with a first switch in series and is therefore divided into a source end and a loading end. The electronic-circuit units are connected in series between the loading end and the second transmission line. The controllers are electrically connected with and are configured for synchronously controlling the first switch and the electronic-circuit units. When the first switch is closed, electric power is transferred from an electric power source to the loading end, and when the first switch is opened, the electronic-circuit units transfer signals via the loading end. The system features simple circuitry and effectively reduces noise in signal transmission.
