Show image.
It therefore,, can be with before client generates image data if the structural parameters of image data and LED light battle array mismatch
Image to be displayed is adjusted according to the structural parameters of preset LED light battle array.For example, the structural parameters of LED light battle array be 413 ×
295, it indicates in LED light battle array, every a line has 413 all-colour LED lamp beads, share 295 rows, and the picture for including of image to be displayed
Size and above structure parameter mismatch, then client can be according to above structure parameter to each of image to be displayed figure
Piece carries out pixel merging or newly-increased, makes the matching of image to be displayed Yu LED light battle array, that is, the institute for including by image to be displayed
There is picture to be converted into 413 × 295 size.
Wherein, structural parameters can be inputted by user, can also by the executing subject of control method provided in this embodiment,
I.e. the control device of LED light battle array is sent to client in advance.
S302, multiple colors codings are generated according to the image data of image to be displayed.
Wherein, each color coding corresponds to a kind of color, and each of LED light battle array all-colour LED lamp bead is equal
Corresponding color coding.
Color coding, can be the binary coding of image data.Specifically, if image data is based on rgb color mould
What formula generated, it is assumed that the corresponding vector of one of pixel is (110,200,89), then, by by the three of this vector
A component (i.e. digital) is converted into binary number one by one, and three binary number combinations must arrive the corresponding color of this pixel and compile
Code.
It should be noted that each component should be converted into order to make each color coding have unified format
The identical binary number of digit.In image data based on rgb color schema creation, in order to indicate whole in 0 to 256 range
Number, each component should be expressed as one 8 binary numbers, and corresponding color coding is equivalent to the two of one 24
System number.
For example, being based on above-mentioned regulation, the color that vector (1,2,1) is converted to is encoded, and should be indicated are as follows:
000000010000001000000001.Wherein, from left to right, preceding 8 expressions one-component 1, intermediate 8 indicate second
A component 2, last 8 expression thirds component 1.
According in abovementioned steps to the introduction of image data, it is found that each pixel of image to be displayed is right
An all-colour LED lamp bead of LED light battle array is answered, for example, the 2nd row of LED light battle array, the all-colour LED lamp bead of the 3rd column, are equivalent to aobvious
2nd row of diagram picture, the pixel of the 3rd column.Therefore, color corresponding with the pixel coding that step S302 is converted to, together
When also correspond to the all-colour LED lamp bead in LED light battle array.Meanwhile each pixel, corresponding vector indicate a kind of face
Color is encoded by the color that the vector is converted to, it is clear that corresponding in this color that the vector indicates.
S303, multiple colors coding is sent to corresponding all-colour LED lamp bead, shows the LED light battle array described to aobvious
Diagram picture.
Wherein, each color coding is used to control corresponding all-colour LED lamp bead and shows that the color encodes corresponding face
Color.
It is each in LED light battle array in the case that each of LED light battle array all-colour LED lamp bead shows specific color
A all-colour LED lamp bead, is equivalent to a pixel of image to be displayed, and all pixel combinations may make up figure to be shown
Picture.Therefore, if by color coding be sent to corresponding all-colour LED lamp bead, so that it may reach control LED light battle array show it is aforementioned to
Show the effect of image.
Need to illustrate when, color coding is sent to corresponding all-colour LED lamp bead described in step S303, will when practical
Each color coding, is converted into the control signal of all-colour LED lamp bead, then sends control signals to corresponding all-colour LED
Lamp bead.
Further, if the video data that image data is made of multiple continuous pictures, in above mentioned step S3 02
Image data is converted into color coding, refers to, for each picture in video data, this picture is converted into corresponding to
The color code set constituted is encoded by multiple colors.The coding of transmission color described in step S303, refers to, sends every one by one
The corresponding color code set of picture.
For example, being converted into 10 color code sets, each color coding for the video data being made of 10 pictures
It include that multiple colors encode correspondingly with the all-colour LED lamp bead of LED light battle array in set.Then, first is sent first
The corresponding color code set of picture makes LED light battle array show the first picture, waits after a certain period of time, sends the second picture
Corresponding color code set, makes LED light battle array show the second picture, and so on, show that LED light battle array one by one above-mentioned
10 pictures achieve the effect that show video.
The present embodiment provides a kind of control method of LED light battle array, after the image data for receiving image to be displayed, according to image
Data generate multiple color codings, and multiple colors coding is then sent to corresponding all-colour LED lamp bead, shows LED light battle array
Image to be displayed；Wherein, each color coding corresponds to a kind of color, and each of LED light battle array all-colour LED lamp bead is right
A color coding is answered, color coding shows corresponding color for controlling corresponding all-colour LED lamp bead.The present invention utilizes basis
Each all-colour LED lamp bead issues particular color in the color coding-control LED light battle array that the image data of image to be displayed generates
Light, so that all all-colour LED lamp beads in LED light battle array is constituted image to be displayed, to achieve the effect that control LED light battle array.
In previous embodiment, color coding is sent to corresponding all-colour LED lamp bead, really obtains color code conversion
To after control signal, control signal is sent to corresponding all-colour LED lamp bead.Wherein, right for different all-colour LED lamp beads
The form that signal should be controlled is also not exactly the same.Below with reference to another embodiment offer of the application by WS2812 or WS2812b
The control method of the LED light battle array of composition introduces the mistake by color code conversion at the corresponding control signal of WS2812 or WS2812b
Journey.Referring to FIG. 4, method provided in this embodiment the following steps are included:
S401, the image data for receiving image to be displayed.
S402, multiple colors codings are generated according to the image data of image to be displayed.
Wherein, each color coding corresponds to a kind of color, and each of LED light battle array all-colour LED lamp bead is corresponding
One color coding.
S403, it is encoded for each color, by the color code conversion at corresponding control sequential signal.
Control sequential signal is a kind of variation using high level and low level duration to transmit the control of information
Signal, two kinds of all-colour LED lamp beads of WS2812 and WS2812b, is exactly controlled by control sequential signal.
The external pin of WS2812 below with reference to Fig. 5, and as shown in connection with fig. 1 briefly introduces control sequential signal.
The input terminal of WS2812 shown in FIG. 1, can under the control of coupled processor (for example, single-chip microcontroller),
It is arranged to high level or low level, and processor can also control high level and low level duration.Meanwhile
The current control chip of WS2812 can be determined according to the duration and low level duration of the high level of input terminal
Input signal is 0 or 1.As shown in figure 5, if input terminal is arranged to low level, and continue 0.9 microsecond, it is then converted into high electricity
It is flat, and continue 0.35 microsecond, it is equivalent to have input signal 0 to WS2812；If input terminal is arranged to low level, and continues
0.35 microsecond then switches to high level and continues 0.9 microsecond, is equivalent to have input signal 1 to WS2812.It is used for like this
The high level of the lasting preset time of expression 0 or 1 and low level combination, become a control sequential, multiple continuous controls
Timing constitutes a control sequential signal.
As previously described in a prior embodiment, if image data is indicated based on rgb color mode, the face of each all-colour LED lamp bead
Color coding, is exactly one 24 binary numbers, and each of these position is indicated with 0 or 1, and therefore, a color is compiled
Code, as long as being converted into control sequential as shown in Figure 5 for each of these position is corresponding, 24 control sequentials connection compositions
This color encodes corresponding control sequential signal, this control sequential signal is sent to corresponding WS2812, is equivalent to
Have input corresponding color coding.
S404, multiple control sequential signals are sent to corresponding all-colour LED lamp bead, LED light battle array is made to show figure to be shown
Picture.
Wherein, WS2812 can parse corresponding color coding from control sequential signal, it can be considered that control
Clock signal can control corresponding all-colour LED lamp bead display color and encode corresponding color.
The specific method for sending multiple control sequential signals is related to the connection type of multiple WS2812 in LED light battle array.One
The common connection type of kind is:
The adjacent WS2812 with any two in a line, the output end of one of them are connect with another input terminal,
All WS2812 for being equivalent to same a line connect into a LED light strip.Positioned at one end of a LED light strip, not with other
The input terminal of the WS2812 of the output end connection of WS2812 is waited as the input terminal of this LED light strip positioned at this LED
The other end, output end of the output end for the WS2812 not connect with the input terminal of other WS2812 as this LED light strip.
On the basis of above-mentioned connection, since LED light battle array on one side, (i.e. the first row is all for first LED light strip
The LED light strip that WS2812 is connected into) output end connect with the input terminal of Article 2 LED light strip, the output of Article 2 LED light strip
End reconnects the input terminal of Article 3 LED light strip, and so on.Fig. 2 can be referred to herein.The input terminal of first LED light strip
It is connect with control device, for receiving control sequential signal from control device.
For the connection type of above-mentioned LED light battle array, the multiple control sequential signals for needing to send are according to corresponding WS2812
Distance form a control sequential signal stream as shown in FIG. 6.All control sequential signals in control sequential signal stream will
It is sent one by one since control sequential signal 1.
After control sequential signal is issued, first WS2812 connecting with control device will be firstly received control sequential
Signal 1 so first WS2812 intercepts control sequential signal 1, and issues the corresponding light of control sequential signal 1, for rear
The continuous control sequential signal 2 passed through does not respond to these to control sequential signal n, first WS2812 and controls signal, but will
They are transmitted by output end to second WS2812.Similarly, second WS2812 will intercept control sequential signal 2 and sending pair
Then the light answered directly transmits control sequential signal 3 and its subsequent control sequential signal.That is, each WS2812
Only respond itself received first control sequential signal, issue corresponding light, subsequent control sequential signal then directly to
After transmit, and so on, until the last one WS2812.
It should be noted that a control sequential signal stream, can only control LED light battle array and show a picture.It needs to use LED
Lamp array shows video, that is, continuously displays the occasion of plurality of pictures, with reference to the video control sequential of Fig. 6, should send multiple
Control sequential signal stream, and between two adjacent control sequential signal streams be inserted into reset signal (duration be greater than or
Equal to the low level of 50 microseconds).
Its concrete principle is after issuing first control sequential signal stream, and LED light battle array shows first control sequential signal
Corresponding picture (control sequential signal stream 1) is flowed, then control device sends a reset signal, receives reset signal
WS2812, the color for still maintaining current light is constant, but when can respond first control received after reset signal
Sequential signal, and show the light of this control sequential signal corresponding color.Therefore, second control is retransmited after sending reset signal
Clock signal stream processed, so that it may when so that the color of itself light being switched to second control by each WS2812 in LED light battle array
The color of corresponding control sequential signal in sequential signal stream is equivalent to LED light battle array and shows that second control sequential signal stream is corresponding
Picture, and so on, until the corresponding control sequential signal stream n of the last one picture, LED light battle array is made to continuously display multiple figures
Piece achievees the effect that show video.
The present embodiment mainly describes the method based on the control of control sequential signal by the WS2812 LED light battle array formed, when
So, for the LED light battle array being made of control mode and WS2812 almost the same WS2812b, method provided in this embodiment is same
Sample is applicable in.
In conjunction with the method that previous embodiment provides, another embodiment of the application provides a kind of control method of LED light battle array again,
Referring to FIG. 7, method includes the following steps:
S701, the client having connected is judged whether there is.
The client having connected if it exists thens follow the steps S702, and the client having connected if it does not exist then continues to execute
This step, until being present in client and establishing connection.
Optionally, the judgement of step S701, on the one hand can be passively, that is, whether real-time detection receives client
Connection request, just establish connection with the client after receiving connection request, and judge there is the client that has connected；It is another
Aspect can be the sending connection request signal of active, and whether real-time detection receives the response of client, if receiving response just
Connection is established with client, and judges there is the client having connected.
S702, the image data for receiving image to be displayed.
Image data is sent by the client having connected.
Whether S703, the image data for judging image to be displayed are complete image data.
If the image data of image to be displayed is complete image data, S704 is thened follow the steps；If image to be displayed
