Description
Technical field
The utility model relates to the Power over Ethernet technical field, is specifically related to a kind of advertisement video based on the Power over Ethernet technology and throws in terminal.
Background technology
Current advertisement is almost ubiquitous, the airport, and the square, the sub-district building, places such as market and even train are all occupied by each big digital media advertisement.Digital media advertisement is integrated management by initial discrete administration change gradually also, and promptly a video server is as control desk, and other video equipment is only done playback terminal.Software, the medium maintenance cost of advertising media simplified in the management of composite type greatly.But because the differentiation that terminal power supply environment exists must be equipped with professional electrician and carry out site operation when operations involving high pressure; Environment is abominable because some scene powers simultaneously, thereby causes the problem of power terminal equipment fault and even equipment fault to happen occasionally, and has directly caused the system maintenance cost higher.Usually in order to adapt to complicated power supply environment, equipment must adopt the reliability service of special power supply with assurance equipment, thereby causes cost also can not to be in any more.High performance graphics capability of super low-power consumption and computing capability have obtained extensive use under the effort of each large chip manufacturer on the other hand, realize directly that with less power consumption scheme the broadcast of high-resolution video advertisement has become possibility.
The utility model content
In view of this,, the utility model proposes a kind of advertisement video based on the Power over Ethernet technology and throw in terminal in order to address the above problem, by Power-over-Ethernet, safe in utilization, need not to consider high-tension line operations involving high pressure problem.
The purpose of this utility model is achieved in that based on the advertisement video of Power over Ethernet technology throws in terminal, comprise a network interface, described network interface is electrically connected with the power input of Power over Ethernet module, and the power output end of described Power over Ethernet module is electrically connected with system's supply module of throwing in terminal based on the advertisement video of Power over Ethernet technology.
Further, described advertisement video based on the Power over Ethernet technology is thrown in terminal and is also comprised network transformer and network card chip, the input of described network transformer is electrically connected with network interface, and the signal output part of network transformer is electrically connected with the signal input part of network card chip;
Further, described network interface is the RJ-45 interface;
Further, comprise AC/DC isolated variable circuit in the described Power over Ethernet module.
The utility model is with respect to prior art, have following advantage: the utility model can pass through Power-over-Ethernet, safe in utilization, need not to consider high-tension line operations involving high pressure problem, solve playback terminal powerup issue effectively in various complicated power supply environment places, safe in utilization, need not to consider high-tension line operations involving high pressure problem; Further, the holding wire that the RJ45 interface is inserted is linked into respectively behind Power over Ethernet module and the network transformer respectively to be connected with network card chip with the system supply module and provides support for terminal provides system required DC power supply support and network data communication, be implemented on the basis of single cable to throw in required telemanagement of video ads Data Update and data transport functions are provided when terminal provides the power supply supply for advertisement video, have advantages such as simple in structure, easy to use.Simultaneously terminal equipment does not have the direct access of high-tension electricity, and the Power over Ethernet module adopts the advertisement video that is designed to of isolated power supply to throw in terminal saved human cost widely when simplifying site operation, and safety guarantee is provided.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 shows the structural representation of throwing in terminal based on the advertisement video of Power over Ethernet technology;
Fig. 2 shows the electrical block diagram of throwing in Power over Ethernet module in the terminal based on the advertisement video of Power over Ethernet technology.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
Referring to Fig. 1, advertisement video based on the Power over Ethernet technology is thrown in terminal, comprise embedded main board and display device etc., the shared network cable line of this terminal power supply power taking and network data signals, also comprise a network interface, common described network interface adopts the RJ-45 interface, can be connected with Cat.5 class network cable line, described network interface is electrically connected with POE (the Power Over Ethernet) power input of Power over Ethernet module and the input of network transformer respectively, the power output end of described Power over Ethernet module is electrically connected with system's supply module of throwing in terminal based on the advertisement video of Power over Ethernet technology, and the signal output part of network transformer is electrically connected with the signal input part of network card chip.
Referring to Fig. 2, comprise AC/DC isolated variable circuit in the described Power over Ethernet module, feedback circuit adopts the optocoupler pipe to detect, and can be this advertisement terminal and eliminates power surge etc. reliable guarantee is provided.
After this terminal accesses to support POE power supply ethernet network, Power over Ethernet module on the embedded main board will provide type to discern and select MID-SPAN or END-SPAN powering mode to carry out power taking to front end PSE end power supply, through providing the system power supply support of maximum 25W to be given to system's supply module (SYS POWER) after the Power over Ethernet module converts; Network signal then passes through and is connected to network card chip (LAN CHIP) behind the network transformer (Transformer) and provides support for the data link of system.
