Abstract
A signal transmission device includes an Ethernet connection port, a magnetic circuit and a power transmission circuit. The Ethernet connection port is configured to be electrically connected to a set of signal equipment and to receive a power signal and a data signal provided by and to output the data signal to a system circuit via a second port. The power transmission circuit is configured to convert a supplying power of the power signal into a DC device power and to output a first power to the system circuit and a second power to the smart device according to the DC device power.
Claims5
