Description
Technical field
The address that the present invention relates to the concatenation unit in combination arranges technology, specifically, relates to a kind of method of Lookup protocol concatenation unit address.
Background technology
Combination a kind of to be arranged by row, column by multiple spliced display unit, the display system that of composition is large, for splicing, segmentation display multiway images; This system adopts centralized control platform, completes the function setting such as passage bridge, Image Adjusting to each display unit by the interface such as serial ports, network interface.It is crucial that the rank addresses of each display unit correctly will be arranged in combination, just correctly can control on centralized control platform like this, otherwise there will be that unit is not controlled, the not reciprocity problem of Image display position.
The general toggle switch that uses on spliced display unit arranges rank addresses at present, for the position toggle switch of conventional 8, when applying, toggle switch is connected on 8 I/O mouths of control chip, the 1-4 position of toggle switch is used for arranging row address, 5-8 position is used for arranging column address, use 8421 yards, 1st, the weights of 5 are 1,2nd, the weights of 6 are 2,3rd, the weights of 7 are 4,4th, the weights of 8 are 8, so when under the 2nd of toggle switch and the 7th is dialled, represent current spliced display unit and are placed in the 2nd row, the 3rd row.The method simple, intuitive, but have the following disadvantages: 1, need to use toggle switch and some peripheral components, increase system cost, once related device breaks down, owing to effectively cannot arrange address, this spliced display unit is by uncontrolled, and reliability is low; 2, a large amount of I/O mouth of control chip is taken; 3, toggle switch limited bits, for 8 toggle switchs, the maximum splicing can only supporting 15 row 15 row, cannot be applicable to large-scale combination address and arrange; 4, each display unit could use after needing dial-up in advance to arrange address, needs dial-up again after changing cell position.
Summary of the invention
Technical matters to be solved by this invention is: a kind of method proposing Lookup protocol concatenation unit address, solve in conventional art adopt toggle switch be arrange increase system cost that rank addresses brings, reliability low, the problem that large-scale combination address arranges cannot be applicable to.
The present invention solves the problems of the technologies described above adopted technical scheme:
A method for Lookup protocol concatenation unit address, comprises the following steps:
A. by the control signal wire of each row concatenation unit, order is connected from left to right, and is connected by the control signal wire of the concatenation unit of the concatenation unit with next every trade head that are positioned at lastrow end of line;
B. in the steering order sending to concatenation unit, add the numbering i of the total columns n of combination and active cell, the value of the numbering i of described active cell is initialized to 1;
C. concatenation unit is when receiving steering order, the value of the columns n total according to combination and the numbering i of active cell calculates the row, column address of this concatenation unit at combination automatically, and the value of the numbering i of the active cell in steering order is added up form new steering order after 1 and send to next concatenation unit, return step c.
Further, in step c, the value of the numbering i of the described columns n total according to combination and active cell automatically calculates this concatenation unit and at the concrete grammar of the row, column address of combination is:
Row address r=(i-1)/n rounds rear+1;
Column address c=i-n* (r-1).
The invention has the beneficial effects as follows: automatically calculate the row, column address of concatenation unit in combination by software mode, do not need to configure extra hardware device, system cost can be reduced, save hardware resource, the stability of raising system, and the address that can be applicable to the concatenation unit in large-scale combination is arranged.
Accompanying drawing explanation

Fig. 2 is the method flow diagram of the Lookup protocol concatenation unit address in the present invention.
Embodiment
The present invention is intended to a kind of method proposing Lookup protocol concatenation unit address, solve in conventional art adopt toggle switch be arrange increase system cost that rank addresses brings, reliability low, the problem that large-scale combination address arranges cannot be applicable to; Its main thought is: be that the steering order received by concatenation unit automatic butt carries out dissection process, according to the total columns of spelling wall in steering order and current number information, carry out corresponding computing, calculate the row, column address of concatenation unit.
Each self-corresponding correct current number information can be obtained to allow each concatenation unit, need the control signal wire exact connect ion of each concatenation unit, for the combination that concatenation unit that is capable by M, N row forms, as shown in Figure 1, its connected mode is: each row is connected by control signal wire from left to right, and the concatenation unit that the concatenation unit of the end of line of lastrow is first with the row of next line is connected by control signal wire.
As shown in Figure 2, the method flow of the Lookup protocol concatenation unit address in the present invention comprises the following steps:
1, be linked in sequence each concatenation unit: by the control signal wire of each row concatenation unit, order is connected from left to right, and is connected by the control signal wire of the concatenation unit of the concatenation unit with next every trade head that are positioned at lastrow end of line;
2, in steering order, add total columns n of combination and the numbering i of active cell, initialization i=1; In the steering order sending to concatenation unit, add the numbering i of the total columns n of combination and active cell, the value of the numbering i of described active cell is initialized to 1;
3, the rank addresses that the concatenation unit receiving steering order calculates in combination automatically according to the value of n and i: concatenation unit is when receiving steering order, and the value of the columns n total according to combination and the numbering i of active cell calculates the row, column address of this concatenation unit at combination automatically;
Form new steering order after 4, i=i+1 is set and send to next concatenation unit: adding up to the value of the numbering i of the active cell in steering order forms new steering order after 1 and send to next concatenation unit, returns step 3.
On concrete enforcement, in steering order two byte is defined as and spells the total columns n of wall and active cell numbering i, the value of active cell numbering i is initialized to 1, based on the annexation of each concatenation unit above-mentioned, steering order always enters from first (being positioned at the 1st row the 1st to arrange) concatenation unit, the now active cell numbering i=1 of this concatenation unit, when receiving steering order, this concatenation unit is according to its row, column address in combination of following formulae discovery:
Row address r=(i-1)/n rounds rear+1;
Column address c=i-n* (r-1).
And this concatenation unit sends to next concatenation unit after forming new steering order together with other information in steering order after the value of the active cell numbering i in steering order is performed accumulation operations (i.e. i=i+1), so, when the concatenation unit of the first row secondary series receives steering order, resolve the value of active cell numbering i, now i=2, it is still by its row, column address in combination of above-mentioned formulae discovery, in this manner, each concatenation unit being arranged in combination all can calculate the row, column address at combination automatically.
