Problems solved by technology

[0003] In the existing technology, electricity can already be supplied uninterruptedly, but in some occasions, due to cost or other reasons, some areas still cannot realize power supply. For example, in some power tunnels or mountainous environments, The 220VAC AC does not have full coverage, and it is necessary to provide the necessary power supply for these environments
[0004] Specifically, in the power tunnel, some tunnels do not completely cover the AC220V power supply, and only have 220AC power supply at the location of the water pump, but the entire tunnel needs video monitoring, and the tunnel can only use safe DC voltage power supply, the traditional The method cannot meet this demand, and cannot realize the power supply of the entire tunnel environment

Embodiment 1

[0044] This embodiment discloses a distributed closed-loop intelligent power supply system applied to remote power feeding, which is used in scenarios where the power supply is not completely covered, including:

[0045] Through multiple power supplies arranged in a distributed manner, the multiple power supplies are connected through a bus, and the bus mounts multiple load devices;

[0046] Each power supply has a built-in intelligent controller, and the intelligent controller of each power supply communicates with the mounted load equipment through the field bus to obtain the real-time current and voltage of each load equipment in real time;

[0047] The intelligent controller is used to monitor its own current output and combine the real-time current and voltage of the load device to perform closed-loop control to supply power to the load device.

[0048] In the environment without 220VAC power supply, the technical proposal of the present disclosure adopts remote power fee...

Embodiment 2

[0067] The purpose of this embodiment is to provide a power supply method applied to remote power feeding distributed closed-loop intelligent power supply, including:

[0068] The intelligent controller of each power supply communicates with the mounted load equipment through the field bus, and obtains the real-time current and voltage of each load equipment in real time;

[0069] The intelligent controller is used to monitor its own current output and combine the real-time current and voltage of the load device to perform closed-loop control to supply power to the load device.

[0070] In a specific implementation example, when the intelligent controller monitors the increase of its own current output, it automatically adjusts the voltage to increase, and monitors the load feedback current and voltage information in real time until the terminal needs are met, and reports the adjustment information to the monitoring platform;

[0071] When the output current of the power suppl...

Abstract

The invention provides a distributed closed-loop intelligent power supply system applied to remote feed and a power supply method, which are used in a scene without completely covering power supplies. The system comprises a plurality of power supplies which are arranged in a distributed manner, the plurality of power supplies are connected through a bus, and a plurality of load devices are mounted on the bus; each power supply is internally provided with an intelligent controller, the intelligent controller of each power supply communicates with the mounted load device through a field bus, and real-time current and voltage of each load device are obtained in real time; and the intelligent controller is used for carrying out closed-loop control to supply power to the load device by monitoring the current output of the intelligent controller and combining the real-time current and voltage of the load device. In an environment without 220VAC power supply, power supply is realized in a remote feed and distributed mode, and the power supply and utilization requirements of some environments such as power tunnels or mountainous areas are ensured.

Description

technical field [0001] The disclosure belongs to the technical field of intelligent power supply, and in particular relates to a distributed closed-loop intelligent power supply system and a power supply method applied to remote power feeding. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In the existing technology, electricity can already be supplied uninterruptedly, but in some occasions, due to cost or other reasons, some areas still have the phenomenon that power supply cannot be realized. For example, in some power tunnels or mountainous environments, The 220VAC AC does not have full coverage, and it is necessary to provide the necessary power supply for these environments. [0004] Specifically, in the power tunnel, some tunnels do not completely cover the AC220V power supply, and only have 220AC power supply at the location of t...
