Embodiment Construction

[0025] In the traditional technology, the standard POE power supply circuit is an independent circuit device, which mainly realizes the power management function through the PSE chip. For example, the models of the PSE chip include: TPS2384 series, TPS23861 series; however, due to the internal circuit of the PSE chip The structure has been fixed during the design and manufacturing process, so the circuit functions realized by the PSE chip cannot be adjusted arbitrarily according to the power supply requirements of the powered equipment. When technicians apply the PSE chip to the standard POE power supply circuit, the standard POE power supply circuit can only It can realize the preset power conversion function for the power supply, and the standard POE power supply circuit can only realize the power-on process for specific powered equipment, and the compatibility is low; and because the function of the PSE chip is complex, the internal circuit structure of the PSE chip contains ...

Abstract

The invention belongs to the technical field of power supply over Ethernet, and provides a non-standard POE power supply circuit, power supply equipment and power supply method for network ports; the non-standard POE power supply circuit is connected with a POE power supply and a network cable interface, and the network cable interface includes a network port signal line And network port power cord, non-standard POE power supply circuit includes: switching module, power-on detection module, control module, power-off detection module and power supply module; when the powered device is not powered on, the power-on detection module can detect the network cable interface Whether there is a powered device connected; when the network cable interface is connected to the powered device, the control module generates a power enable signal, and the power supply module outputs the power signal of the POE power supply to the network port power line according to the power enable signal; when the powered device After normal communication with the network cable interface, the power-on detection module can be disconnected from the network port signal line through the control module; the invention solves the problems of high power supply cost and low flexibility of the traditional POE power supply circuit.

Description

technical field [0001] The invention belongs to the technical field of power supply over Ethernet, and in particular relates to a non-standard POE power supply circuit for network ports, power supply equipment and a power supply method. Background technique [0002] With the rapid development of network communication, Ethernet is a new type of network media transmission method. Due to its fast data transmission rate and many advantages such as long-distance communication, Ethernet has become the mainstream communication of network equipment. way; in the Ethernet communication system, the mobile device needs to be connected to the power supply in real time to realize the corresponding physical function. The traditional technology usually adopts the POE power supply (Power Over Ethernet, Power over Ethernet) circuit to realize the charging process for the mobile device, and the POE power supply The circuit can provide stable DC power for mobile terminals without any changes to...
