Embodiment Construction

[0040] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The power supply equipment of POE in the prior art is PSE, which only includes one power supply, namely Device Power (such as figure 1 shown). PSE is the power supply device for POE. When powering POE, DevicePower is the power supply for POE.

[0042] Device Power supplies power to POE through the control of PSE Control and Switch Control, and PSE Control and Switch Control also need power to work, so DevicePower also serves as the device power supply of PSE Control and Switch Control. At the same time, DevicePower also supplies power to modules such as MAC.

[0043] The POE power supply equipment uses a high-power power supply, usually with a rated power of 150W-1000W. The no-load loss (inheren...

Abstract

The invention provides a power supply device of a power over Ethernet (POE) and a power supply method. The power supply device of the POE comprises a device power supply, a power supply, a device control module and a power supply control module. The power supply and an access of the device power supply and the power supply control module can be disconnected under the condition that no power is supplied to the POE. The power supply and the access of the device power supply and the power supply control module are connected when the power is supplied to the POE. Accordingly, unified and systemic management control of the modules in the power supply device of the POE is achieved, and electric energy consumption in the power supply and the device power supply is further reduced. In addition, the power-on time of the power supply and the power supply control module is decreased, and the service life of the power supply, the device power supply and the power supply control module is prolonged.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a POE power supply device and a method for controlling power supply of the POE power supply device. Background technique [0002] POE (Power Over Ethernet) can realize Ethernet network power supply through 10BASE-T, 100BASE-TX, 1000BASE-T. A network cable can supply power. This technology is currently widely used and can be used in power supply solutions for IP phones, wireless APs, portable device chargers, card readers, cameras, and data acquisition. [0003] A complete POE system includes two parts: PSE (Power Sourcing Equipment, power supply equipment) and PD (Powered Device, powered equipment). Among them, the PSE is a device that supplies power to Ethernet client devices, and is also a manager of the entire POE Power over Ethernet process. The PD is the PSE load that receives power, that is, the client device of the POE system, such as IP phones, network securi...
