In above-mentioned view data transmittance process, view data generally includes the address information of the concatenation unit of specifying, and accordingly, concatenation unit also must include corresponding mark ID, just can receive view data, represent.
In prior art, the mark ID of concatenation unit generally produces algorithm by professional ID and produces or determined by the mark of the hardware device of concatenation unit inside.
But in technique scheme, the implementation procedure being produced algorithm generation concatenation unit mark ID by professional ID is comparatively complicated; And depend on hardware device based on the method for hardware device, in the skimble-scamble situation of read method that the mark of the hardware device in concatenation unit can not separate from the tag slot of other hardware cells or the hardware device of different concatenation unit identifies, then the method based on hardware device then can not realize; Therefore the applicability based on the method for hardware device is poor.
Summary of the invention
In order to solve above-mentioned purpose, the present invention proposes a kind of concatenation unit mark ID generation method, the method is easy to realize and have stronger applicability, and solving professional ID that prior art provides, to produce algorithm generating identification ID implementation procedure complicated and based on the poor defect of the method applicability of hardware device.
To achieve these goals, technical scheme of the present invention is:
A kind of LED display splicing system concatenation unit mark ID generation method, wherein LED display splicing system is a combination, this combination comprises one or more region, region comprises some concatenation units, carry out exchanges data between contiguous concatenation unit, described mark ID generation method comprises the following steps:
S1. send generating identification id command by signal access link to the first concatenation unit, generating identification id command includes the positional information of the first concatenation unit;
S2. the first concatenation unit receives generating identification id command, and utilizes the positional information generating identification ID in generating identification id command;
S3. after generating identification ID, the first concatenation unit processes the positional information in generating identification id command, obtains the generating identification id command of contiguous concatenation unit, and this generating identification id command is delivered to corresponding concatenation unit;
S4. S2, S3 is repeated until all concatenation units all generate mark ID in combination or region.
Compared with prior art, beneficial effect of the present invention is:
LED display splicing system concatenation unit mark ID generation method provided by the invention is easy to realize, and has good applicability, overcomes the technological deficiency that mark ID generation method implementation procedure is complicated and applicability is poor that prior art provides.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but embodiments of the present invention are not limited to this.
Embodiment 1
As shown in Figure 1, 2, 3, the LED display splicing system that the present invention relates to is a combination, and this combination comprises 2 regions, is respectively region 1 and region 2, separate between region 1 and region 2, does not exchange the function of data.Wherein include several concatenation units in each region, the upside of concatenation unit, downside, left side, right side are respectively arranged with data-interface A, C, B, a D in order to communicate with adjacent concatenation unit.
The present invention is that the LED display splicing system be spliced by above-mentioned multiple concatenation unit provides a kind of concatenation unit mark ID generation method.The method comprises the following steps:
S1. send generating identification id command by signal access link to the first concatenation unit, generating identification id command includes the positional information of the first concatenation unit;
S2. the first concatenation unit receives generating identification id command, and utilizes the positional information generating identification ID in generating identification id command;
S3. after generating identification ID, the first concatenation unit processes the positional information in generating identification id command, obtains the generating identification id command of contiguous concatenation unit, and this generating identification id command is delivered to corresponding concatenation unit;
S4. S2, S3 is repeated until all concatenation units all generate mark ID in combination or region.
In the present embodiment, concatenation unit is after receiving the generating identification id command sent, and concatenation unit can judge whether to process this generating identification id command, if so, then ignores this generating identification id command; If not, then the positional information in generating identification id command is utilized to generate the mark ID of concatenation unit.
Wherein, positional information is region line information or whole wall line information, and region line information comprises the line number numerical value of concatenation unit in this region and row numerical value, and whole wall line information comprises the line number numerical value of concatenation unit in whole combination and row numerical value.The mark ID generated based on region line information is unique in this region, may be the same with the mark ID of a certain concatenation unit in other regions, but does not affect the communication of this concatenation unit in this region; And be all unique in combination based on the mark ID that whole wall line information generates.
In the present embodiment, adopt and without symbol 32 integers, mark ID is represented, wherein high 16 bit representation line number numerical value, low 16 bit representation row numerical value, in described positional information, the line number numerical value row_num=X of concatenation unit, row numerical value col_num=Y, then identify ID=X × (2^16)+Y.
In the present embodiment, the respective handling in step S3 is specific as follows:
If adjacent concatenation unit is positioned at the left side of concatenation unit, then in the positional information after respective handling, line number numerical value row_num=X, row numerical value col_num=Y-1;
If adjacent concatenation unit is positioned at the right side of concatenation unit, then in the positional information after respective handling, line number numerical value row_num=X, row numerical value col_num=Y+1;
If adjacent concatenation unit is positioned at the upside of concatenation unit, then in the positional information after respective handling, line number numerical value row_num=X-1, row numerical value col_num=Y;
If adjacent concatenation unit is positioned at the downside of concatenation unit, then in the positional information after respective handling, line number numerical value row_num=X+1, row numerical value col_num=Y.
In LED display splicing system provided by the invention, concatenation unit mark ID generation method is easy to realize, and has good applicability, overcomes the technological deficiency that mark ID generation method implementation procedure is complicated and applicability is poor that prior art provides.
