Embodiment Construction
[0022] Aiming at the problem that the DC power supply distance of communication equipment is short in the current use environment or the terrain is relatively complex, and a booster device needs to be added in order to realize long-distance power supply, the present invention controls the start-up of multiple power supply modules according to the real-time power consumption of multiple external terminals. closed, so that the voltage output by multiple power modules matches the real-time power consumption, a longer distance DC power supply can be realized without adding a booster device, and the power supply requirements in different business application scenarios can be met. The power supply of the present invention The circuit is safe and reliable, the design cost is low, the expandability is strong, and the power supply distance is long, which can effectively control and improve the load carrying capacity.
[0023] The following will clearly and completely describe the techni...

The embodiment of the invention discloses a power supply circuit which comprises a control circuit, a communication circuit, a plurality of power supply modules and a power supply output port, whereinthe control circuit is electrically connected with the control end of each power supply module, the output ends of the power supply modules are electrically connected with the input end of the powersupply output port, the output end of the power supply output port is connected with a plurality of external terminals through power supply cables, and the control circuit communicates with the external terminals through the communication circuit; the control circuit can obtain the real-time power consumption of a plurality of external terminals and control the on-off of a plurality of power supply modules so that the voltages outputted by a plurality of power supply modules are matched with the real-time power consumption. On-off of a plurality of power supply modules is controlled accordingto the real-time power consumption of a plurality of external terminals so that the voltages outputted by a plurality of power supply modules are matched with the real-time power consumption, longer-distance direct current power supply can be realized without additionally arranging boost equipment, and the power supply requirements under different service application scenes are met.
Description
technical field [0001] The invention relates to the field of power supply, in particular to a power supply circuit. Background technique [0002] It has always been a relatively big problem to realize long-distance DC power supply for communication equipment in the occasions where the use environment or terrain is complex and does not have normal power supply. At present, due to load consumption and cable loss of long-distance DC power supply equipment, the power supply distance is often difficult to reach 10KM, and even if such a long-distance power supply can be achieved, it is usually necessary to add a booster device in the middle. Contents of the invention [0003] In view of the above technical problems, an embodiment of the present invention provides a power supply circuit. [0004] An embodiment of the present invention provides a power supply circuit, the power supply circuit includes a control circuit, a communication circuit, a plurality of power supply modules...
