Description

一种拼接墙控制方法及其装置,拼接墙系统技术领域 A construction apparatus and method of controlling the wall, the wall system splicing Field

[0001] 本发明涉及显示拼接墙技术领域,尤其涉及一种拼接墙控制方法、一种拼接墙控制装置以及一种拼接墙系统。 [0001] The present invention relates to a display wall technology, and more particularly, to a method for controlling display wall A control device and a video wall display wall system. 背景技术 Background technique

[0002] 随着显示拼接墙技术的发展,拼接墙技术的应用变得越来越广泛,常用的拼接墙有两种实现方式:显示单元开窗和多屏处理器开窗,其中,显示单元开窗的方式是指在拼接墙的控制端向组成拼接墙的各个显示单元传输控制指令,各个所述显示单元在接收到控制指令后根据所述控制指令打开对应的窗口。 [0002] With the development of display display wall technology, the application display wall technology is becoming more widespread, common mosaic wall in two ways: window display unit and multi-screen processor window, wherein the display unit windowed mode refers to the control terminal of each of the display mosaic wall unit transmits control command composed of mosaic wall, each opening corresponding to the display window unit according to the control instruction after receiving the control command.

[0003] 现有技术中,实现显示单元开窗的方式根据对各个所述显示单元传输控制指令的方式不同,又可以分成两种类型:一种是通过网络对各个所述显示单元传输控制指令,另一种是通过单个串口对各个所述显示单元传输控制指令。 Embodiment [0003] In the prior art, to realize the display unit for each window in accordance with various transmission control instruction to the display unit of the embodiment, and can be divided into two types: one is a network element of each of said transmission control instruction display the other is a transmission control instruction to each unit of the display by a single serial port. 如果是通过单个串口对各个所述显示单元传输控制指令,则通常采用串口环接线连接多个所述显示单元,并通过所述串口环接线对各个所述显示单元传输控制指令。 If the serial port is a single transmission unit of the respective display control instructions are usually connected to a plurality of serial loop connection of said display unit through said serial connection ring transmission control instruction to each unit of the display.

[0004] 请参阅图1,图1是现有技术通过串口控制的拼接墙系统的工作流程图。 [0004] Referring to FIG. 1, FIG. 1 is a flowchart of the prior art by splicing the serial control wall system.

[0005] 所述拼接墙系统包括组成拼接墙的多个显示单元、控制界面,控制逻辑服务和串口通信设备。 The [0005] system comprising a plurality of mosaic wall mosaic wall display units, control interface, and a serial communication service control logic device. 各个所述显示单元通过串口环接线连接,所述控制逻辑服务通过所述串口通信设备的一个串口对各个所述显示单元发送控制指令。 Each of said display unit is connected through a serial connection ring, said control logic unit transmits a control command serving for each of the display through a serial communication port of the device. 由于串口的传输特性,每个控制指令只能分时依次发送至所述串口连接线中,而不能够并行发送。 Since the characteristics of serial transmission, each of the time division sequence control instruction can be sent to the serial cable, without the parallel transmission is possible. 所述控制指令对应各个所述显示单元编码,所述控制指令在所述串口环接线中传输时,只有指定的显示单元可以从所述串口环接线读取对应的可控制指令。 The display control instruction corresponding to the respective encoding means, the control instruction in the serial transmission terminal ring, only wiring may be specified in the display unit reads the corresponding control instruction from the serial port can ring.

[0006] 在步骤S101,所述控制界面向所述逻辑服务发送拼接墙的控制指令; [0006] At step S101, the control interface is a control instruction to the video wall service logic;

[0007] 在步骤S102,所述逻辑服务根据各个所述显示单元的划分方式,进行逻辑运算,将所述拼接墙的控制指令转换为对各个所述显示单元的控制指令; [0007] In step S102, the service logic respective division manner the display unit, performs a logic operation, the control command into a video wall of each control command in accordance with said display unit;

[0008] 在步骤S103,所述逻辑服务向所述串口通信设备发送显示单元1的控制指令; [0008] In step S103, the display control instruction service logic unit 1 transmits to the serial communication device;

[0009] 在步骤S104,所述串口通信设备向所述显示单元1发送控制指令; [0009] In step S104, the serial communication device to the display unit 1 transmits a control command;

[0010] 在步骤S105,所述显示单元1通过所述串口通信设备向所述逻辑服务返回处理结果{曰息; [0010] In step S105, the display unit 1 returns the processing result to the service logic by the serial communication device {said information;

[0011] 在步骤S106,所述逻辑服务接收所述显示单元1返回的处理结果信息后,向所述串口通信设备发送显示单元2的控制指令; After [0011] In step S106, the service logic unit 1 receives the processing result information returned by the display, display control instruction to the transmitting unit 2 of the serial communication device;

[0012] 在步骤S107,所述串口通信设备向所述显示单元2发送控制指令; [0012] In step S107, the serial communication device to the display unit 2 transmits a control instruction;

[0013] 在步骤S108,所述显示单元2通过所述串口通信设备向所述逻辑服务返回处理结果fe息。 [0013] In step S108, the display unit 2 returns the processing result to the logic fe information service through the serial communication device.

[0014] 重复执行上述步骤向所有的显示单元依次发送控制指令,并接收处理结果信息。 [0014] Repeat the above steps sequentially transmits control commands to all of the display unit, and receives the processing result information. 在接收所有的显示单元的处理结果信息之后,所述逻辑服务进一步通过所述串口通信设备向各个所述显示单元依次发送同步指令,并接受同步响应结果信息,最后所述逻辑服务向面返回所述拼接墙控制指令的执行结果。 After receiving all of the processing result display unit information, the service logic is further to each of the display by means of the serial communication device sequentially transmits a synchronization instruction, and in response to receiving the synchronization result information, and finally returns the service logic to the surface said execution result display wall control command.

[0015] 由上述工作流程可知,现有技术的拼接墙的控制方法中,由于对各个所述显示单元的控制指令只能分时依次发送至所述串口连接线中,而不能够并行发送,因此必须要接收到前一显示单元的控制指令执行结果信息时,才能够对下一显示单元发送控制指令,并且确认每一所述显示单元都收到控制指令后,还必须发送同步信号使各个所述显示单元的响应能够同步。 [0015] From the above workflow control method of the prior art display wall, since the control instruction to each unit of the display time-sequentially sent only to the serial cable, without the parallel transmission is possible, must be received before a control command execution result display unit when the information display unit to be able to send the next control instruction, and each of the display to confirm receipt of the control instruction units, it must also transmit the respective synchronization signal in response to the display unit can be synchronized. 所以执行一个拼接墙控制指令的通信时间会比较长,并且随着拼接墙的显示单元数目增多,此问题将会越来越明显,甚至使拼接墙的响应变得非常慢,影响用户的操作的流畅度。 Therefore, the implementation of a video wall control command communication time will be longer, as the number of the display unit and display wall, this problem will become increasingly apparent, even to respond mosaic wall becomes very slow, the influence of the operation of the user fluency. 发明内容 SUMMARY
