Description
Technical field
The present invention relates to screen splicing field of display technology more particularly to the ID automatic setting methods and dress of liquid crystal-spliced screen
It sets.
Background technique
The application most important in the industry of liquid crystal-spliced screen products exactly " is spliced ", i.e., muti-piece mosaic screen shows one jointly
Signal pattern needs clearly to be combined which block mosaic screen and is used to show that a width completely to be drawn before completing concatenation
Face then must complete the setting of splicing function by selecting the ID serial number of this several pieces of mosaic screens.And in liquid crystal-spliced screen complete machine
Before factory, the ID serial number of every piece of mosaic screen is all consistent.When site operation, the dial-up shielded by adjusting every piece is needed to open
Pass value or the independent ID of each single screen is set by infrared signal, is had not to form screen all in a project
Same ID sequence number value, to realize the purpose of splicing control function.
The prior art increases toggle switch behind every piece of liquid crystal-spliced screen, and toggle switch is generally 8 adjustment positions, respectively
Corresponding row value setting (4) and train value adjustment (4), each can be set on or off, is equipped with dial-up in this way and opens
The large-size screen monitors of pass can support the splicing scale of 16*16 in principle, and in this splicing scale, the dial-up value of each piece of mosaic screen is all
It is different, it is uniquely, to guarantee the configuration that can carry out service application in entire combination.What every piece of liquid crystal single screen was dispatched from the factory
When, dial-up value is the same, and is required to carry out the setting of dial-up value for each piece of mosaic screen at the scene, be formed different
ID serial number is just able to satisfy project splicing application.
And for the case where infrared signal is configured, there is infrared signal on the Driver Card of each mosaic screen unit
Receiver, by an external infrared signal line, to receive the setting instruction that IR remote controller is issued.Similarly, for spelling
The ID serial number setting for connecing screen unit can carry out single screen by remote controler and be arranged one by one, at the scene during practice of construction, need
Before large-size screen monitors hang up bracket, it is arranged by the ID serial number that hand-guided remote controler carries out single screen.
Due in the prior art, ID value either being arranged by dial-up mode or IR signal reception mode, due to each
There is no communications between mosaic screen unit, therefore it is independent to every piece of mosaic screen unit one by one by hand to be required to site operation personnel
It is configured, not only workload is bigger, is also easy to occur the case where two pieces or more of single screen is configured with the same ID value, separately
It is external when do above-mentioned configuration, after the ID for needing to pre-set each piece of single screen, then the construction of large-size screen monitors is carried out, because once
After large-size screen monitors have been placed on bracket, then be adjusted just it is relatively difficult because in general data large-size screen monitors all be superposition installation,
It is highly relatively high, it is not easy to operate after installing.
Existing technology main problem is to need artificially to configure ID value one by one, is very easy to occur in the provisioning process
Muti-piece single screen is configured to the same ID value, to cause splicing business unavailable.
Summary of the invention
In order to solve the problems existing in the prior art, the present invention provides a kind of methods of ID setting, so that ID setting is simple
And it is not easy to make mistakes.
A kind of ID automatic setting method of liquid crystal-spliced screen, for each mosaic screen formed in complete liquid crystal-spliced screen
The setting of unit progress ID value, comprising:
Each mosaic screen unit is sequentially connected in series by preset order, keeps information between the two neighboring mosaic screen unit of concatenation mutual
It is logical；
Select a mosaic screen unit as start unit after set start unit ID value；
From start unit respectively to the spelling for being connected to before start unit and being connected to after start unit in both direction
It connects screen unit and sends the ID value, on single sending direction, each mosaic screen unit is after receiving ID value by default
Progressive law ID value increase as itself ID value, and the ID value after increase is sent to along sending direction next
Mosaic screen unit, until being sent to the last one mosaic screen unit；Wherein, the ID value progressive law on two sending directions makes institute
Some mosaic screen unit ID values are all different.
In method of the invention, start unit be it is arbitrarily selected, by ID value to different directions transmit and be incremented by come reality
The purpose that existing ID is arranged automatically, is not needed the setting for artificially carrying out each mosaic screen unit, is guaranteed using progressive law same
Each ID value is different on one direction, and by guaranteeing that the limitation of progressive law, ID value all after being arranged is all different,
It avoids that the efficiency that the mistake for duplicating setting improves splicing is manually arranged, considerably increases convenience.
Such as the odd number that can make the ID value on one of sending direction incremental with progressive law, the other side are to be incremented by
Even number.If next mosaic screen unit is not present on one of sending direction of start unit, directly at another
It is incremented by sending direction according to progressive law.
Furthermore, it is different to meet the ID value parity on two sending directions for the progressive law.
Two sides parity is different, then can guarantee that there is no identical ID values in both direction, and same on single direction
Since ID value is incremental therefore is also impossible to generate repetition, this mode can be to avoid ID value in transmitting setting
The mistake for repeating setting is generated in the process.Both direction will guarantee that the different progressive law of parity has very much, for example, side with
2 n times side is incremented by, and the other side is incremented by with 3 n times side.
Furthermore, the ID value of the start unit is set as a, and wherein on a sending direction, progressive law meets
The ID value a+2N-1 of n-th mosaic screen unit after N-1 times sends, on another sending direction, progressive law meets warp
The ID value for crossing n-th mosaic screen unit after sending N-1 times is a+2N, and wherein a is positive integer.
This progressive law be it is the simplest, expense when calculating is smaller, for example, a is 1, connects before start unit
Mosaic screen unit ID value progressive law is a+2N-1, and connecing the mosaic screen unit ID value progressive law after start unit is a+2N,
Then the available mosaic screen unit ID value connect before start unit is respectively 2,4,6,8 etc., connects the spelling after start unit
Connecing screen unit ID value is respectively 1,3,5,7 etc..
Furthermore, the ID value of the start unit is set by infrared signal transmission.
It using method of the invention, can be carried out again after mosaic screen unit assembles, to avoid first powering on one by one
The repetition operation process of re-assemble after the setting of ID value is dismantled again is carried out, and after assembly, since entire mosaic screen is larger, and select
Fixed start unit is likely located at middle position, more not convenient if the setting for carrying out ID value by the way of toggle switch,
Therefore the setting that ID value can be remotely carried out using infrared signal transmission, is improved ID value and convenience is arranged.
Furthermore, each mosaic screen unit includes upstream Interface for connecting previous mosaic screen unit and is used for
The downstream interface for connecting the latter mosaic screen unit uses the first progressive law on the direction sent forward, is sending backward
Direction on use the second progressive law, when mosaic screen unit receives ID value from upstream Interface, using the first progressive law
Increase ID value, and when mosaic screen unit receives ID value from downstream interface, ID value is increased using the second progressive law.
Due to start unit be it is arbitrarily selected, each mosaic screen unit carry out ID value it is incremental when, need to judge
Received ID value is to send from which direction, therefore the interface of ID value is received by judgement, can learn ID value
Direction of transfer, thus using corresponding progressive law increase ID value.
To implement method of the invention, the present invention also provides corresponding ID, and device to be arranged automatically, to solve to need one by one
It carries out ID value and generated fallibility and inconvenient problem is set.
Device is arranged in a kind of ID of liquid crystal-spliced screen automatically, for each mosaic screen formed in complete liquid crystal-spliced screen
The setting of unit progress ID value, comprising:
Each mosaic screen unit is sequentially connected in series by ID value sending module by preset order, makes the two neighboring mosaic screen of concatenation
Information mutual communication between unit；
Originate ID setup module, select one mosaic screen unit as start unit after by originate ID setup module set
The ID value of start unit；
ID value increases module, to before being connected to start unit and is connected to respectively from the ID value sending module of start unit
Mosaic screen unit after start unit in both direction sends the ID value, on single sending direction, each mosaic screen list
The ID value of member increases module and carries out ID value by preset progressive law after receiving ID value to increase the ID as itself
Value, and the ID value after increase is sent to next mosaic screen unit along sending direction, until being sent to the last one mosaic screen
Unit；Wherein, the ID value progressive law on two sending directions is all different all mosaic screen unit ID values.
Start unit be it is arbitrarily selected, transmitted and be incremented by realize mesh that ID is arranged automatically to different directions by ID value
, the setting for artificially carrying out each mosaic screen unit is not needed, guarantees that each ID value is not in the same direction using progressive law
Together, it and by guaranteeing the limitation of progressive law ID value all after being arranged is all different, avoids that appearance is manually arranged
The mistake for repeating setting improves the efficiency of splicing, considerably increases convenience.
Furthermore, it is odd to increase the ID value that the progressive law in module meets on two sending directions for the ID value
Idol is different.
Two sides parity is different, then can guarantee that there is no identical ID values in both direction, and same on single direction
Since ID value is incremental therefore is also impossible to generate repetition, this mode can be to avoid ID value in transmitting setting
The mistake for repeating setting is generated in the process.Both direction will guarantee that the different progressive law of parity has very much, for example, side with
2 n times side is incremented by, and the other side is incremented by with 3 n times side.
Furthermore, the ID value of the start unit is set as a by the starting ID setup module, wherein a transmission
On direction, progressive law meets the ID value a+2N-1 of the n-th mosaic screen unit after N-1 times sends, in another sender
Upwards, it is a+2N that progressive law, which meets the ID value of the n-th mosaic screen unit after N-1 times sends, and wherein a is positive integer.
Furthermore, the ID value of the start unit passes through the infrared signal receiver in the starting ID setup module
It is configured.
This progressive law be it is the simplest, expense when calculating is smaller, for example, a is 1, connects before start unit
Mosaic screen unit ID value progressive law is a+2N-1, and connecing the mosaic screen unit ID value progressive law after start unit is a+2N,
Then the available mosaic screen unit ID value connect before start unit is respectively 2,4,6,8 etc., connects the spelling after start unit
Connecing screen unit ID value is respectively 1,3,5,7 etc..
Furthermore, the ID value sending module of each mosaic screen unit includes for connecting previous mosaic screen unit
Upstream Interface and downstream interface for connecting the latter mosaic screen unit are incremented by rule using first on the direction sent forward
Rule uses the second progressive law on the direction sent backward, connects when the ID value of mosaic screen unit increases module from upstream Interface
When receiving ID value, ID value is increased using the first progressive law, and connect from downstream interface when the ID value of mosaic screen unit increases module
When receiving ID value, ID value is increased using the second progressive law.
Due to start unit be it is arbitrarily selected, each mosaic screen unit carry out ID value it is incremental when, need to judge
Received ID value is to send from which direction, therefore the interface of ID value is received by judgement, can learn ID value
Direction of transfer, thus using corresponding progressive law increase ID value.
Present invention mainly solves liquid crystal-spliced screens in project beginning, can automatic, quickly, accurately, easily be arranged every
The ID serial number of block single screen.Without carrying out artificial setting one by one for every piece of single screen in combination, as long as choosing any one spelling
Screen unit is connect, automatic setting instruction is assigned by one key of IR remote controller, whole mosaic screen units in combination can be completed
