Description

Embedded mainboard with but a plurality of independent net gapes POE power supply

Technical Field

The utility model belongs to the technical field of network security application, embedded mainboard technique and specifically relates to an embedded mainboard that but has a plurality of independent net gapes POE power supply is related to.

Background

Embedded motherboards generally fall into two broad categories: RISC-based ARM embedded motherboard and X86-based embedded motherboard. X86-based embedded motherboards (typically using INTEL, weisheng, AMD or other vendor's X86 chips such as Taiwan RDC, taiwan ICOP, etc.); an ARM embedded mainboard based on RISC (ARM company authorizes production, and each chip manufacturer has own special function). Embedded ARM boards are typically onboard CPUs, while x86CPU based motherboards are not necessary.

POE (Power Over Ethernet) refers to a technology that can provide dc Power for some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) while transmitting data signals for such devices without any modification of the existing Ethernet cat.5 wiring infrastructure, which is the latest standard specification for transmitting data and electric Power simultaneously by using the existing standard Ethernet transmission cable and maintains compatibility with the existing Ethernet system and users, POE is also called a Power Over LAN (POL) or an Active Ethernet (Active Ethernet), and is sometimes referred to as Ethernet Power supply for short, and is usually referred to as networking and Power supply through a network cable, so that excessive connection between a Power adapter and a cable can be avoided, thereby saving installation cost and time, and the POE Power supply end device can only supply Power for the devices that need Power supply. The ethernet cable will only have voltage present if the equipment to be powered is connected, thus eliminating the risk of leakage on the line.

The ethernet power supply technology is based on the premise that small network devices such as an IP phone, a WLAN access point, and a network camera can directly obtain power from an ethernet cable (idle 2 pairs of 4 twisted pairs for transmission), and a power line does not need to be laid separately, so as to simplify system wiring and reduce the construction cost of network infrastructure.

In addition to the need to transmit video signals over the network cable, a typical webcam must also provide sufficient power for it at all times. In actual construction, a problem that a large amount of scene power adapters are used and a problem that a disordered electric wire is hidden need to be solved by designing an embedded mainboard capable of supplying power through a POE (power over Ethernet) port because a stable power supply cannot be provided often.

It should be noted that the above background description is only for the sake of clarity and complete description of the technical solutions of the present invention, and is set forth for facilitating understanding of those skilled in the art. These technical solutions must not be considered known to the skilled person merely because they have been explained in the technical background section of the present invention.
