Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In an LED light synchronous control system, as shown in fig. 1 and fig. 2, the LED light synchronous control system includes a server 10, a plurality of synchronous terminals 20, a plurality of controllers 30, and LED light bars 40, the server 10 is in communication connection with the plurality of synchronous terminals 20, each synchronous terminal 20 is in communication connection with the plurality of controllers 30, each controller 30 is in communication connection with the plurality of LED light bars 40, and all the LED light bars 40 are arranged in a preset shape.
In order to ensure that the LED light bars 40 controlled by each synchronization terminal 20 synchronously display the pictures of the same frame, in the present application, each synchronization terminal 20 generates a schedule of each frame of picture according to the synchronized local time, and sends the picture data of the corresponding time frame to the controller 30 according to the schedule; and analyzing the sending time of the picture data of each frame, and reducing the size of the preset sending interval when the sending time exceeds the preset time so as to ensure that the sending time and the sending completion time of the picture data of each frame are basically the same in each synchronous terminal 20, thereby realizing that the LED light bars 40 controlled by all the synchronous terminals 20 synchronously display the pictures of the same frame. The following describes the embodiments of the present application in detail.
As shown in fig. 3, an embodiment of the present application provides a method for synchronously controlling LED lights, including:
s100, acquiring picture data, playing time parameters and a lighting arrangement diagram, wherein the picture data comprises a plurality of frames of pictures.
The LED light synchronization control method of the present embodiment is executed by the synchronization terminal 20. The picture data refers to the picture content of the corresponding area of the LED light bar 40 controlled by the synchronous terminal 20, and may include several frames of pictures. The playing time parameter mainly includes a playing period, and may further include a frame rate and other control parameters. The lighting map includes the connection relationship between the controller 30 and the LED light bar 40, and may further include the position of the LED light bar 40 in a predetermined shape.
In step S100, the sync terminal 20 may directly acquire the picture data and the play time parameter from the server 10. At this time, the server 10 may divide the entire program file to obtain the picture data corresponding to each of the sync terminals 20. The complete program file includes the picture data of all the sync terminals 20, which is complete picture data of the entire area.
In addition to the division of the program file by the server 10, the synchronization terminal 20 may divide the program file by itself to obtain screen data belonging to itself. In this case, step S100 may specifically include: the synchronous terminal 20 acquires the complete program file, the playing time parameter and the light arrangement diagram from the server 10; the synchronous terminal 20 divides the complete program file according to the lighting map to obtain the picture data.
The division of the complete program file by the synchronization terminal 20 may also be performed without the aid of a lighting map. The synchronous terminal 20 can obtain the complete program file, the playing time parameter and the area data of the synchronous terminal 20 from the server 10; the sync terminal 20 intercepts picture data from the complete program file according to the region data. In this case, the program file does not need to be divided according to the lighting map.
It is understood that the synchronization terminal 20 may obtain the lighting arrangement map from the server 10, or may store the lighting arrangement map itself.
S200, calculating the picture working data mapped to each pixel point according to each frame of picture and the lighting map.
After the synchronous terminal 20 obtains the picture data, the picture working data corresponding to each pixel point on the LED light bar can be calculated accordingly. The picture data comprises a plurality of frame pictures. For each frame of picture, data mapped to each pixel point is determined according to the lighting map. Because every pixel actually comprises LED lamp pearl, consequently, can also further convert the required work data of LED lamp pearl work into. The working data of all the pixel points of the LED light bar controlled by each synchronization terminal 20 form the picture working data of each frame of picture.
It can be understood that each pixel point can be composed of a single-color LED lamp bead, and also can be composed of three or more LED lamp beads.
And S300, calculating a playing time table of each frame of picture according to the synchronized local time and the playing time parameter, and storing the playing time table in association with the working data of each frame of picture.
The synchronous terminal 20 can calculate the playing time table of each frame of picture, i.e. the specific and accurate playing time of each frame of picture, according to the synchronized local time and the playing time parameter. Then, the play schedule is associated with the picture operation data for each frame and then stored in the memory so as to be directly read at the time of actual play without recalculation.
In calculating the play schedule, the local time used is the synchronized local time. In this way, it is possible to ensure time synchronization of all the synchronization terminals 20, and to ensure that the play schedules calculated therefrom are the same.
The local time synchronization of the synchronization terminal 20 may be performed in step S300 or before step S300, that is, each time the play schedule is calculated, the local time may be synchronized first; before step S100, as shown in fig. 4, step S010: the local time is synchronized.
The synchronization of the local time may be performed by one of the methods such as GPS time synchronization, network time service, and time synchronization by a mobile communication base station. Preferably, the synchronization terminal 20 synchronizes the local time by using a time synchronization method based on a mobile communication base station.
And S400, reading the picture working data of the corresponding time frame at a preset time according to the playing time table, and sending the picture working data outwards, wherein the sending of the picture working data of each frame has a preset sending interval.
According to the play schedule, the synchronous terminal 20 reads the picture working data of the corresponding time frame at the preset time and sends the data to the outside. The picture operation data corresponding to the time frame may include only one frame of picture operation data, or may include multiple frames of picture operation data. The picture working data of the corresponding time frame to be transmitted can be packed into a data packet, such as a UDP data packet. In addition to the frame work data of each frame, the data packet may further include address data, port number, channel number, and the like of the controller 30, so as to help the controller 30 quickly obtain the data corresponding to itself from the data packet.
Generally, the transmission of the data packets may be performed in a broadcast form or in an on-demand form. When broadcasting is used, the picture operation data of all the controllers 30 is packed into one packet and then broadcast to all the controllers 30. When the on-demand broadcasting is adopted, the picture working data corresponding to each or a plurality of controllers 30 are respectively packed into one data packet, and then are sent to the corresponding controllers 30 point-to-point.
The transmission of the screen work data for each frame has a preset transmission interval so that the controller 30 can effectively distinguish the screen work data for each frame when receiving the data. For example, when the picture working data of a preset time frame only includes picture working data of multiple frames, in a data packet obtained by correspondingly packaging, a bit corresponding to a preset sending interval length may be set after the picture working data of each frame; when the frame work data of the preset time frame only includes the frame work data of one frame, the preset transmission interval may be a transmission time interval of adjacent data packets.
In order to improve the execution efficiency of step S400, the synchronization terminal 20 may read the frame work data of several frames from the memory in advance according to the play schedule, and store the frame work data in the buffer. The buffer can be a Cache memory or a buffer on the memory. In this way, by caching the data in advance, the time for the central processing unit of the synchronous terminal 20 to read the data from the memory is reduced, and especially when a large amount of data is processed, the delay influence of the time consumed by reading the data on the subsequent transmission can be reduced.
S500, acquiring the sending completion time of the picture working data of the corresponding time frame, and judging whether the time is overtime.
When the transmission of the screen work data of each frame is completed, the synchronization terminal 20 obtains the transmission completion time of the screen work data of the corresponding time frame, that is, the transmission time of the screen work data of the corresponding time frame.
A standard transmission time may be set in advance, or calculated according to the frame rate in the play time parameter. For example, assuming a frame rate of 30 frames/second, the standard transmit time may be calculated as 1/30 ≈ 33 ms.
Comparing the sending completion time of the picture working data of the corresponding time frame with the standard sending time, and if the sending completion time is smaller than the standard sending time, judging that the sending is not overtime; if the former is larger, it is a timeout.
S600, if the time is judged to be overtime, adjusting the preset sending interval according to the overtime time, and sending the picture working data of the next corresponding time frame according to the adjusted sending interval.
When the time-out is judged, the sync terminal 20 adjusts the preset transmission interval. Generally, the preset transmission interval is adjusted and decreased correspondingly according to the timeout time. And then, when the picture working data of the corresponding time frame of the next time is transmitted, the adjusted preset transmission interval is used.
In this way, the time schedule of all the synchronous terminals is ensured to be the same by setting the respective time schedule calculated based on the synchronous local time for each frame of picture. By adjusting the preset sending interval, even if the sending of the picture working data of a certain frame is overtime, the picture working data of the next frame can be ensured to be sent and completed in time, so that the sending time and the sending and completing time of the picture data of each frame in each synchronous terminal 20 are basically the same, and the LED light bars 40 controlled by all the synchronous terminals 20 can synchronously display the pictures of the same frame. By the scheme of the embodiment, the synchronization of most of the picture frames can be guaranteed, and even if one frame of picture is overtime, the phenomenon of obvious pause can not occur, and the asynchronization of subsequent frames can not be caused.
In some embodiments, step S500 is not required, i.e., the determination of whether the transmission completion time is timed out is not required. As shown in fig. 5, after step S400, step S800 is executed to adjust a preset transmission interval required for the screen working data of the corresponding time frame at the next time according to the transmission completion time of the screen working data of the corresponding time frame at the current time. Therefore, the sending interval can be preset in the dynamic adjustment period for the picture working data of each time frame, so that the sending completion time of the picture working data of each corresponding time frame is basically the same in a real-time scene, and the sending of the front and rear frames according to the playing time schedule is effectively guaranteed.
For example, the preset transmission interval of the corresponding time frame at the next time may be dynamically determined according to a difference between the transmission completion time of the screen work data of the corresponding time frame at the previous time and the standard transmission time. Therefore, by dynamically adjusting the preset sending interval for sending each frame, the sending of the front and rear frames according to the playing time table can be effectively ensured, and the synchronous display of the pictures of the same frame by the LED lamp strips 40 controlled by all the synchronous terminals 20 is realized.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
