Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 2, the distributed splicing television curtain wall system that the utility model provides comprises the display screen 2 of distributed video driving control system and some mutual splicings.
Distributed video driving control system comprises some drive plates 1.Drive plate 1 comprises at least one input interface 101 for input of control commands and at least two for exporting the output interface 102 of control command.In each drive plate 1, one of them drive plate 1 is the drive plate 1 that the output of the 1st grade of drive plate 1, n-th grade of drive plate 1 connects is (n+1)th grade of drive plate 1, n >=1.That is to say, in this control system, except the 1st grade of drive plate 1 only has except one, the quantity of other drive plates 1 at different levels is all unfixed, and a certain drive plate 1 is which grade drive plate 1 depends on that the input interface 101 of this drive plate 1 is connected with the output interface 102 of which rank of drive plate 1, instead of pre-determined.Such as, if the input interface 101 of a certain drive plate 1 is connected with the output interface 102 of the 1st grade of drive plate 1, then this drive plate 1 is just the 2nd grade of drive plate 1, if the input interface 101 always having 2 drive plates 1 in this control system is connected with the output interface 102 of the 1st grade of drive plate 1, then just there are 2 the 2nd grade of drive plates 1 in this control system, if the input interface 101 of a certain drive plate 1 is connected with the output interface 102 of the 2nd grade of drive plate 1, then this drive plate 1 is just 3rd level drive plate 1, if the input interface 101 always having 6 drive plates 1 in this control system is connected with the output interface 102 of the 2nd grade of drive plate 1, then just there are 6 3rd level drive plates 1 in this control system, other drive plates 1 at different levels by that analogy.After the syndeton of each drive plate 1 is determined in control system, from the 1st grade of drive plate 1, could determine that other each drive plates 1 are the quantity of which grade drive plate 1 and drive plate at different levels 1 respectively.
In control system, the input interface 101 of the 1st grade of drive plate 1 is for accessing external control signal, and at least two output interfaces 102 of the 1st grade of drive plate 1 are connected respectively to the input interface 101 of a 2nd grade of drive plate 1.Preferably each output interface 102 of the 1st grade of drive plate 1 is connected respectively to the input interface 101 of a 2nd grade of drive plate 1, like this, 1st grade of drive plate 1 has how many output interfaces 102 just will connect how many 2nd grade of drive plates 1, and the drive plate 1 that can more effectively reduce when drive plate 1 quantity is too much connects progression.Respective at least two output interfaces 102 of at least one (n+1)th grade of drive plate 1 are connected respectively to the input interface 101 of the n-th+2 grades drive plates 1, until all drive plates 1 realize connecting.With the 1st grade of drive plate 1 in like manner, preferably each output interface 102 of other drive plates 1 at different levels is also connected respectively to the input interface 101 of a next stage drive plate 1, until all drive plates 1 all realize connect.Progression is connected like this by farthest reducing drive plate 1 when drive plate 1 quantity is too much.
In this control system, due to each drive plate 1 have multiple output interface 102 to export respectively identical control command also not to receive control command drive plate 1 to other simultaneously, the mode of traditional series-connected transmission control command is equivalent to become communication modes by relay node broadcasts control command, greatly reduce the connection progression of drive plate 1 in screen test, reduce in command transfer the probability occurring mistake.
Each drive plate 1 comprises 1 input interface 101 and at least 3 output interfaces 102 in principle.When each drive plate 1 comprises 1 input interface 101 and 3 output interfaces 102, if 3 output interfaces 102 of the 1st grade of drive plate 1 to be connected respectively to the input interface 101 of a 2nd grade of drive plate 1, respective 3 output interfaces 102 of other drive plates 1 at different levels are connected to the input interface 101 of a next stage drive plate 1 respectively, and the drive plate 1 reduced when drive plate 1 quantity is too much is to the full extent connected progression.Fig. 1 and Fig. 2 is contrasted known, adopt traditional when being connected in series mode, the connection progression comprising drive plate 1 in the screen test of 12 pieces of display screens 2 reaches 12 grades, and when adopting connected mode as shown in Figure 2, drive plate 1 connects progression and only has 5 grades, in Fig. 2, if respective 3 output interfaces 102 of drive plate at different levels 1 are connected to the input interface 101 of a next stage drive plate 1 respectively, until all drive plates 1 realizes connecting, drive plate 1 connects progression and can be reduced to further and only have 3 grades.
Input interface 101 and the output interface 102 of each drive plate 1 can adopt serial ports or network interface, because the cost of netting twine is lower than Serial Port Line cost, and do not need the turn of the screw when installing, can shorten the set-up time, reduce material cost and time cost, preferentially can adopt network interface.The control software design of PC end sends control command by serial ports or network interface, by the input interface 101 of the 1st grade of drive plate 1, control command is inputted the 1st grade of drive plate 1, in control command, contain the control command to each drive plate 1 and each address date driving the drive plate 1 of order correspondence.If input interface 101 and output interface 102 adopt serial ports, the serial port chip of standard can be adopted.
Each drive plate 1 is also provided with toggle switch, each address of drive plate 1 in screen test can be set by the toggle switch of each drive plate 1, be convenient to transmit control command to each drive plate 1.Each drive plate 1 comprises 8 toggle switchs, the address of each drive plate 1 is divided into row and column, the state of the 1 to 4 toggle switch is for representing the column address of drive plate 1 in whole curtain wall, and the state of the 5 to 8 toggle switch is for representing the row address of drive plate 1 in whole curtain wall.Geocoding adopts standard 8421 coded format, and row address is from 0 to 15, and column address, also from 0 to 15, supports 256 pieces of display screens 2 at most like this.
In distributed splicing television curtain wall system, the quantity of drive plate 1 and one_to_one corresponding equal with the quantity of display screen 2, each drive plate 1 connects with corresponding display screen 2, shows for driving corresponding display screen 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
