Coaxial Communication signal and DC Voltage composite circuit and distributed power supply topology for long distance application of single-point to multi-point IP based devices via coaxial cables
The present invention relates to a coaxial line signal and a DC power supply of a single-point to multi-point switched internet protocol (IP) communication configuration method. And AC-DC converter power supplies are also applied in a distributed manner to provide a flexible combination method for long-distance / short-distance field applications. To this end, the present invention provides a coaxial line signal for long distance and a direct current power superposition application circuit of a single-point to multi-point switchable Internet protocol (IP) Shielding inductor; An overcurrent limiting fuse of DC power supplied through a coaxial line; A capacitor for passing a signal for transmitting and receiving coaxial long-distance coaxially transmitted from a signal transformer with a minimum attenuation and shielding a signal transformer by shielding the application of the DC power; And a resistor for discharging the charged charge of the capacitor. In addition, a distributed arrangement structure of a plurality of AC-DC converter (DC-DC converter) DC power supplies is applied, and the relationship between the signal line of the switching Internet protocol (IP) / Features circuit design that is configured to enable the most efficient power supply configuration for short-range system configurations.
