Abstract
The utility model discloses an Ethernet switch capable of displaying the operating state of a PoE (power over Ethernet) system, relates to the technical field of communication, and particularly relates to a PoE switch. The Ethernet switch comprises a shell, a PSE (power sourcing equipment) power supply module, a main power supply module, a DC/DC power supply conversion module and a connecting port, wherein the shell is provided with a display screen, and the display screen is connected with an LCD display unit module and an MCU (micro controller unit) module. The MCU module is communicated with the PSE power supply module, reads the operating state of the PSE power supply module, and displays operating conditions of PSE through the display screen. The operating conditions of the PoE system can be judged quickly by the construction or maintenance personnel through information displayed on an LCD screen by adopting the structure provided by the utility model, thereby reducing the debugging time or the maintenance time of equipment, and improving the work efficiency.
Description
Technical field
The Ethernet switch of a kind of PoE of demonstration working state of system of the utility model relates to communication technical field, especially PoE switch.
Background technology
PoE (Power Over Ethernet) refers in the situation that what existing Ethernet wiring (Cat.3 or Cat.5) architecture do not done and changed, in some IP-based terminals (as IP phone machine, wireless local network connecting point AP, web camera etc.) transmission of data signals for this reason kind equipment the technology of direct current supply is provided.PoE system is by feeder ear equipment (PSE, Power Sourcing Equipment) and receiving end equipment (PD, Power Device) two parts composition.PSE equipment is the equipment for the power supply of ethernet client equipment, is also the manager of whole PoE Power over Ethernet process simultaneously.And PD equipment is the PSE load of accepting power supply, i.e. the client device of POE system, as ethernet devices such as IP phone, web camera, AP.
The switch of prior art is the connection status of indicating PSE and PD by LED light.This technology, owing to being used to refer to the LED negligible amounts of state, is generally 1 LED, whether is only used to refer to port in power supply.But at the scene in application, because there is many factors can have influence on the normal power supply of PoE, user cannot judge fast problem where goes out, and need to investigate one by one and could confirmation problem where go out the wiring of whole system, wastes a large amount of time and manpower.
Also having a kind of prior art is to read the connection status of PSE and PD by web webpage.The mode that reads the connection status of PSE and PD by web webpage need to be used computer expert to cross after network is connected to switch just can read the port of PoE switch and the link information (as information such as connection status, output power, supply voltages) that PD holds.Operational environment to Installation and Debugging personnel or maintenance personal, condition of work, and the network technology of Installation and Debugging personnel or service worker is had relatively high expectations.
Utility model content
The purpose of this utility model is the defect that overcomes above-mentioned prior art, just can see intuitively the operating state of PSE port by LCD display, can judge rapidly the connectivity problem between PSE and PD by these information, reduce PoE switch debugging difficulty or raising maintenance efficiency at the construction field (site).
The technical solution of the utility model: a kind of Ethernet switch that shows PoE working state of system, comprise casing, PSE supply module, main power source module, DC/DC DC power supply conversion module, connectivity port, it is characterized in that being provided with display screen on described casing, described display screen is connected with LCD display unit module and MCU micro controller unit module.
Above-mentioned a kind of Ethernet switch that shows PoE working state of system, described MCU micro controller unit module is communicated by letter with PSE supply module, reads the operating state of PSE supply module, and the working condition of PSE is shown by display screen.
Above-mentioned a kind of Ethernet switch that shows PoE working state of system, described display screen is LCD display.
Adopt technique scheme, MCU micro controller unit module is communicated by letter with PSE supply module by bus, the operating state that reads PSE supply module (comprises the output voltage of power supply, the electric current of port, the power of port, the working temperature of chip, whether PD meets IEEE802.3af standard, the information such as the reason that PSE port is stopped power supply), MCU micro controller unit module is further analyzed these information again, and the working condition of PSE supply module is presented in LCD display intuitively.Construction or maintenance personal just can judge the working condition of PoE system fast by the information showing in LCD display, thereby reduce debug time or the maintenance time of equipment, thereby increase work efficiency.

Embodiment
The technical scheme of the Ethernet switch below in conjunction with accompanying drawing to a kind of PoE of demonstration working state of system of the utility model is described in further detail:
See shown in Fig. 1, Fig. 2, comprise casing 1, PSE supply module 2, main power source module 3, DC/DC DC power supply conversion module 4, connectivity port 6, on described casing 1, be provided with LCD display 7, described LCD display 7 is connected with LCD display unit module 8 and MCU micro controller unit module 9, is used for showing the operating state of PSE supply module 2.
The course of work is as follows:
MCU micro controller unit module 9 is communicated by letter with PSE supply module 2 by bus, the operating state that reads PSE supply module 2 (comprises the output voltage of power supply, the electric current of port, the power of port, the working temperature of chip, the information such as whether PD meets IEEE802.3af standard, the reason that PSE port is stopped power supply), MCU micro controller unit module 9 is further analyzed these information again, and the working condition of PSE supply module 2 is presented in LCD display 7 intuitively.Construction or maintenance personal just can judge the working condition of PoE system fast by the information showing in LCD display 7, thereby reduce debug time or the maintenance time of equipment, thereby increase work efficiency.
Such as:
Embodiment mono-: referring to Fig. 3, the content that when PoE system is normally worked, LCD shows.
ULP: represent that PD load is light, port is not powered.
OLP: represent port overload protection, port is not powered.
SCP: represent port short-circuit protection, port is not powered.
OFF: represent that port does not meet PD, port is not powered.
Non: represent a non-standard PD of port access
Total: represent the power that all of the port consumes.
PB: the gross power that represents PSE power supply.
So, maintenance personal is reading information directly, understands operating state, to take measures pointedly, increases work efficiency.
Embodiment bis-: referring to Fig. 4,
When supply voltage higher limit that the supply voltage of PSE specifies higher than IEEE802.3at (or af) standard, the information that LCD screen display is shown.
Embodiment tri-: referring to Fig. 5, when supply voltage lower limit that the supply voltage of PSE specifies lower than IEEE802.3at (oraf) standard, the information that LCD screen display is shown.
