The invention relates to a transmitting device using direct current carrier waves and a receiving device using direct current carrier waves. The transmitting device using the direct current carrier waves comprises a microcontroller unit, a transmitting end communication circuit unit, an inductive reactance unit, an isolation direct current unit and a direct current power and signal output end. The microcontroller unit is used for receiving an information signal; the transmitting end communication circuit unit is used for converting the information signal into a communication signal; the inductive reactance unit is used for receiving direct current power; the isolation direct current unit is used for preventing the direct current power from affecting the transmitting end communication circuit unit; and the direct current power and signal output end is used for transmitting the direct current power and the communication signal to an electric wire. The invention also discloses the receiving device using the direct current carrier waves. The electric wire can be used for simultaneously transmitting (receiving) the direct current power and the communication signal, so that labor cost and the cost for the electric wire are saved.
Description
technical field [0001] The present invention relates to a transmitting device and a receiving device, in particular to a transmitting device using a DC carrier and a receiving device using a DC carrier. Background technique [0002] An uninterruptible power supply (UPS for short) is an electronic device that provides emergency power to electronic equipment when the input power fails; wherein, the DC uninterruptible power supply system can provide DC power. [0003] Please refer to figure 1 , which is a block diagram for the application of the existing DC uninterruptible power system; a DC uninterruptible power system 10 is electrically connected to an optical network terminal device 20 (optical network terminal, referred to as ONT) through a plurality of wires 30, so as to input Emergency power is provided to the optical fiber network terminal equipment 20 when the power fails. [0004] The first and second wires 30 (at least 18AWG) from top to bottom among the wires 30 ar...
