Problems solved by technology

If a local network device (such as an Ethernet switch) is connected to three remote network devices (such as a wireless network base station), a total of four power supplies are required to make this area network work. However, in some locations farther away from the socket, such as Outdoors, roofs, fences, etc., the network equipment is not easy to connect to the mains socket

Abstract

A power supply device and a power supply system are used for connecting Ethernet cables. The power supply device includes a switch circuit, a power supply circuit and a detection circuit. The power circuit is coupled to the power supply output terminal via the switch circuit. The detection circuit controls the state of the switch circuit according to the first resistance value between the first pin and the second pin of the Ethernet cable. The invention also discloses a power supply system provided with the above power supply device.

Description

technical field [0001] The invention relates to a power supply device and a power supply system, in particular to a power supply device and a power supply system for supplying power through an Ethernet cable. Background technique [0002] All electronic devices need power to perform their work, and so do network devices. With the rapid development of network technology, the use of network equipment is becoming more popular. If a local network device (such as an Ethernet switch) is connected to three remote network devices (such as a wireless network base station), a total of four power supplies are required to make this area network work. However, in some locations farther away from the socket, such as Outdoors, rooftops, fences, etc., network equipment is not easy to connect to the mains socket. [0003] In recent years, a Power over Ethernet (PoE) system has been developed, which consists of a Power Sourcing Equipment (PSE) and a Powered Device (PD). Electricity from th...
