Problems solved by technology

[0017] The embodiment of the present invention provides a power supply method and device based on a POE switch, and a POE switch to solve the problem that when there is a ground loop in the POE system, the existing power supply method based on the POE switch will cause the POE switch to fail due to the inability to detect the AP. Normal supply of power to the AP will cause network interruption, and may burn out the POE switch, causing the POE system to be paralyzed

Embodiment Construction

[0038] When there is a grounding loop in the POE system, the existing power supply method based on the POE switch will cause the POE switch to fail to supply power to the AP due to the inability to detect the AP, which will cause network interruption, and may burn the POE switch, causing the POE system to fail. Paralyzed problem, the embodiment of the present invention provides a kind of power supply method based on POE switch, the flow of this method is as follows Image 6 As shown, the execution steps are as follows:

[0039] S60: Detect whether the PDs of all the ports of the POE switch are in place, and obtain the ports where the PDs are in place.

[0040] Before supplying power, the POE switch first detects the Detect information of all ports, and obtains the port where the PD is in place, which can be the port number and other information. Even if there is a ground loop in the POE system composed of the POE switch and the PD, due to the low presence detection voltage, t...

Abstract

The invention discloses a power supply method and device based on a POE (Power Over Ethernet) switch and the POE switch. The method comprises the steps of: detecting whether PDs (powered device) of all ports of the Ethernet power supply POE switch are in place, and obtaining the ports where the PDs are in place; dividing the obtained ports into at least two groups, wherein at least two ports are arranged in each group; and providing power for the PDs of the ports in each group according to a set time interval, wherein the power is concurrently provided for the PDs of the ports in the same group, and the value of the set time interval is not greater than the value of an overload protection time. The scheme disclosed by the invention ensures that all the ports where the PDs are in place can be supplied with the power, a POE system is stable and a network is smooth, and all the ports can be normally supplied with power before being overloaded.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a power supply method and device based on a POE switch, and the POE switch. Background technique [0002] Power Over Ethernet (POE) technology is a technology that transmits data signals to Ethernet clients while providing DC power supply under the existing Ethernet Cat.5 cabling infrastructure. Ethernet clients can It is an Internet Protocol (Internet Protocol, IP) telephone, a wireless local area network (Wireless Local Area Net, WLAN) access point (Access Point, AP), a network camera, and so on. POE technology can guarantee the normal operation of existing network equipment while ensuring the safety of existing structured wiring, thereby reducing costs to the greatest extent. The existing PoE technology standards include Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.3af and IEEE802.3at. The IEEE 802.3at stand...
