Abstract

The invention discloses a novel distributed weak current power supply system, relates to a distributed power supply system, and solves the problems of a single power supply, poor stability, a complex structure, low conversion efficiency, limited working time of a backup power supply after power failure and the like due to the fact that intelligent weak current power supply depends on an alternating current-to-direct current power supply mode. A direct current bus, a power supply and adapters are included. The power supply comprises solar photovoltaic, a mains supply and a storage battery power supply, the solar photovoltaic is connected to the current bus through a photovoltaic adapter, and the mains supply is connected to the current bus through a corresponding alternating current adapter; and the storage battery power supply is also connected to the power supply bus through the corresponding storage adapter to form an integral distributed direct current power supply system.

Description

technical field [0001] The invention relates to a distributed power supply system, in particular to a novel distributed weak electric power supply system. Background technique [0002] The biggest problem in the management of existing smart home appliances is that the intelligent control part has disconnection and power failure, and power failure is often the main reason for network disconnection. These problems lead to the failure of intelligent control. For example, the existing monitoring network can maintain 70 %Monitoring and not dropping the line is the overall maintenance goal of the network. The main reason for this result is that the existing management grid is generally divided into AC grid and DC grid. In most cases, the AC power in the AC grid is converted into the corresponding DC power. After that, it will be used by electrical equipment, and when the AC power is cut off, UPS or battery is often used to maintain the operation of smart equipment for a short time...
