Abstract

The embodiment of the invention relates to a POE self-adaptive power supply system, method and device. The method comprises: detecting whether power supply equipment is connected with power receivingequipment or not; when the power supply equipment is connected with the power receiving equipment, acquiring the power receiving information and type of the power receiving equipment, and judging whether the power receiving equipment is standard power receiving equipment or not; if so, enabling the control unit of the power supply equipment to control the first switching element to be switched on,and eanbling the power supply unit of the power supply equipment to supply power to the power receiving equipment corresponding to the power of the power receiving equipment; and if not, the controlunit of the power supply equipment controls the second switching element to be conducted, enabling the power supply unit of the power supply equipment to supply power to the powered equipment. The control unit controls the on and off of different switching elements to provide the power supply of the corresponding equipment type for the power receiving equipment, and the problem that the existing POE power supply cannot supply power to the non-standard PD equipment is solved; and the control unit controls the power supply unit to provide a corresponding power supply for the power receiving equipment.

Description

technical field [0001] The present invention relates to the technical field of POE power supply, in particular to a POE self-adaptive power supply system, method and device thereof. Background technique [0002] POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat. etc.) while transmitting data signals, it can also provide DC power supply technology for such devices. [0003] POE is also known as local area network-based power supply system (POL, Power over LAN) or active Ethernet (Active Ethernet), sometimes referred to as Ethernet power supply, which is the use of existing standard Ethernet transmission cables to transmit data and The latest standard specification of electrical power, and maintain compatibility with existing Ethernet systems and users. [0004] The existing POE system includes two parts: PSE (Power Supply Equipment) and PD (Po...
