Abstract
The invention discloses a kind of acquisition methods and device of spelling wall system annexation, first successively send electric signal to display unit, again from video card channel reception electric signal, the order receiving electric signal is contrasted with the order sending electric signal, the annexation of display unit and video card passage can be learnt.Adopt this method and device, only need carry out transmission and the reception of electric signal, without the need to configuring other devices, provide cost savings, what also eliminate other devices arranges work simultaneously.This device and traditional spelling wall system are combined, namely forms spelling wall system of the present invention.According to the thinking of this method and device, traditional spelling wall system is improved, namely form another kind of the present invention and spell wall system.
Description
Technical field
The present invention relates to combination technical field, particularly relate to a kind of spelling wall system annexation collocation method, device and spell wall system.
Background technology
In order to meet the large screen display demand of some special occasions, combination disposal system (be called for short and spell wall system) is arisen at the historic moment.Spell wall system and comprise main frame and some display units, Figure 1 shows that a spelling wall comprising 2 row 3 row display units, main frame is arranged some video cards, as shown in Figure 2, each video card has some passages, each expanding channels display unit.The image of signal source is cut into some parts by main frame, and mails to each display unit respectively by each passage, the different piece of each display unit difference display source signal, and is spliced into complete picture.
Based on above display packing, main frame needs each passage correspondence of determining often to open video card to spell which row of which row of wall, to send the image of corresponding part to each passage, thus is presented at the correspondence position of spelling on wall.The annexation of video card passage and display unit in other words corresponding relation needs to be got by certain method, and is kept in main frame.Traditional acquisition methods comprises following three kinds:
Classic method one
Main frame configures a corresponding table, connect display unit and be connected according to this prefabricated table with when passage.If a video card has 4 passages, then the combination of a 3*2, two video cards are needed to carry out image output.Main frame configures as follows:
First card slot of main frame inserts video card 1,
Passage 1 correspondence of video card 1 spells (1,1) display unit of wall,
Passage 2 correspondence of video card 1 spells (1,2) display unit of wall,
Passage 3 correspondence of video card 1 spells (1,3) display unit of wall,
Passage 4 correspondence of video card 1 spells (2,1) display unit of wall,
Second card slot of main frame inserts video card 2,
Passage 1 correspondence of video card 2 spells (2,2) display unit of wall,
Passage 2 correspondence of video card 2 spells (2,3) display unit of wall,
The passage 3,4 of video card 2 does not carry out image output.
This method, needs the corresponding relation of pre-configured video card passage and display unit, needs to be connected according to corresponding relation above when operator carries out the connection of video card passage with display unit.Therefore, inconvenience is brought to operator.
Classic method two
This method is that each display unit arranges a toggle switch, as shown in Figure 3, connect display unit and during video card passage, be any connection, after spelling wall is spelled, the toggle switch of each display unit is arranged to the value corresponding with affiliated ranks, main frame reads the value of the toggle switch of each display unit by each passage, be worth the corresponding relation of video card passage and display unit according to this.Such as, the toggle switch of (1,1) display unit is arranged as shown in Figure 4, and it is 0000 that main frame reads its value, according to predetermined rule, represents the 0th display unit, corresponds on the spelling wall of 2 row 3 row, is positioned at the 1st row the 1st and arranges.Therefore the image corresponding to the 1st row the 1st row after segmentation is transferred out by current channel by main frame.In like manner, the toggle switch of (2,2) display unit is arranged as shown in Figure 5, and its value is 0100, represents the 4th display unit on the spelling wall that 2 row 3 arrange, i.e. the display unit of the 2nd row the 2nd row.
The remarkable defect of this method needs to configure toggle switch in addition, and arrange toggle switch, and when display unit quantity increases, financial cost and cost of labor increase thereupon.
Classic method three
This method is identical with method two principle, and difference adopts network interface to replace toggle switch, and each network interface has fixing MAC Address, and main frame knows the corresponding relation of display unit and video card passage by reading MAC Address.
Defect and the method two of this method are similar, need to configure extra network interface, add cost.
Summary of the invention
Based on above-mentioned situation, the present invention proposes a kind of spelling wall system annexation acquisition methods, device and spell wall system, to obtain the annexation of display unit and video card passage.
Spell an acquisition methods for wall system annexation, comprise step:
Successively electric signal is sent to each display unit according to predefined procedure;
By the electric signal that each each display unit of video card channel reception sends;
Record the order of each video card channel reception to electric signal, and contrast with described predefined procedure, determine the annexation of video card passage and display unit,
Described display unit for receiving electric signal, and forwards the display unit of electric signal to connected video card passage.
Spell an acquisition device for wall system annexation, comprising:
Electric signal sending module, for successively sending electric signal according to predefined procedure to each display unit;
Electric signal receiver module, for the electric signal sent by each each display unit of video card channel reception;
Order contrasts module, for recording the order of each video card channel reception to electric signal, and contrasting with described predefined procedure, determining the annexation of video card passage and display unit,
Described display unit for receiving electric signal, and forwards the display unit of electric signal to connected video card passage.
A kind of spelling wall system, comprises display unit and video card passage, each described video card expanding channels described display unit, and the annexation of described video card passage and described display unit is arbitrarily, also comprises the acquisition device of above-mentioned spelling wall system annexation.
A kind of spelling wall system, comprise display unit, main frame and the video card passage be arranged on described main frame, each described video card expanding channels described display unit, the annexation of described video card passage and described display unit is any, display unit described in each is according to predetermined cascade system cascade, first order display unit receives electric signal, and transmit to rear class display unit, every grade of display unit receives electric signal and forwards electric signal to connected video card passage, the order of described host record each video card channel reception electric signal, and contrast with described predetermined cascade system, determine the annexation of described video card passage and described display unit.
The present invention spells acquisition methods and the device of wall system annexation, first successively send electric signal to display unit, again from video card channel reception electric signal, the order receiving electric signal is contrasted with the order sending electric signal, the annexation of display unit and video card passage can be learnt.Adopt this method and device, only need carry out transmission and the reception of electric signal, without the need to configuring other devices, provide cost savings, what also eliminate other devices arranges work simultaneously.This device and traditional spelling wall system are combined, namely forms spelling wall system of the present invention.According to the thinking of this method and device, traditional spelling wall system is improved, namely form another kind of the present invention and spell wall system.
