Embodiment Construction

[0043] The invention provides a power supply method and a power supply device to solve the technical problem in the prior art that the power supply equipment cannot supply power to the power receiving equipment because the starting current of the power receiving equipment is too small.

[0044] In the technical solution of the present invention, when the power supply device detects that it is connected to a non-standard power receiving device, it will switch the power supply mode of the power supply device from the first power supply mode to the second power supply mode, and make the power supply device use the first The second power supply mode supplies power to the non-standard powered device, wherein the first power supply mode is used in the power supply device to detect the first The detection chip of the starting current of the powered device defaults to the power supply mode in the enabled state;

[0045] The second power supply mode is a power supply mode in which a de...

Abstract

The invention discloses a power supply method and a power supply method. The power supply method comprises the steps that the conditions that power supply equipment is connected with first power receiving equipment, a power supply function of the power supply equipment is started, but a current power supply state of the first power receiving equipment is in an unpowered state are determined, the first power receiving equipment is determined to be non-standard power receiving equipment, and a current power supply mode of the power supply equipment is switched into a second power supply mode different from a first power supply mode from the first power supply mode, so that the power supply equipment supplies the first power receiving equipment with electricity in the second power supply mode. By the power supply method, the technical problem that the power receiving equipment cannot be supplied with the electricity due to the fact that the power supply equipment detects that starting current of the power receiving equipment is too low in the prior art is solved; and the technical effect of supplying the non-standard power receiving equipment with the electricity is achieved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a power supply method and a power supply device. Background technique [0002] With the advancement of science and technology, the ability to transmit information between people through the Internet is getting faster and faster, which can meet the needs of information exchange between people and things, and between things in a wide area. In terms of Internet construction, because the LAN power supply system can supply power while transmitting data with the help of conventional LAN cables, which saves the trouble of power wiring, it is widely used. [0003] The inventor of the present invention finds that there are following defects in the existing local area network power supply system: [0004] Since there are many types of PD (Power Device, power receiving equipment) equipment, the starting current of each PD is also different. For PD equipment with small starti...
