Non-standard POE power supply circuit and power supply method for network interfaces, and power supply equipment

Abstract

The invention belongs to the technical field of power over Ethernet, and provides a non-standard POE power supply circuit and power supply method for network interfaces, and power supply equipment. the non-standard POE power supply circuit is connected to a POE power supply and a cable interface; the cable interface includes a network interface signal line and a network interface power line; the non-standard POE power supply circuit includes an exchange module, a power-on detection module, a control module, a power failure detection module and a power supply module; whether the cable interfaceis accessed by power receiving equipment can be detected through the power-on detection module when the power receiving equipment is not powered on; after the cable interface accesses the power receiving equipment, the control module can generate power enable signals, and the power supply module can output the power signals of the POE power supply according to the power enable signals; and the power-on detection module can be disconnected to the network interface signal line through the control module after the power receiving equipment in in normal communication with the cable interface. Thus, the problems of high power supply costs and low flexibility of traditional POE power supply circuits can be solved.

Description

technical field [0001] The invention belongs to the technical field of power 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 the ex...
