Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, a distributed display device is provided and is suitable for performing display backup on a spliced screen. As shown in fig. 1, the apparatus includes a control device (not shown in the drawing), a display unit 110, and a double decoding processing unit 120. The number of the display units 110 is multiple and the display units 110 are arranged in an array, and the number of the double decoding processing units 120 is the same as the number of the display units 110. Each display unit 110 forms a display chain according to the principle that the distance between each two display units is the nearest, the dual decoding processing units 120 form a decoding processing node chain, the main signal port of each dual decoding processing unit 120 in the decoding processing node chain is respectively connected with the main input interface of the display unit 110 at the same position in the display chain, the auxiliary signal port of each dual decoding processing unit 120 is connected with the auxiliary input interface of the next display unit 110 of the display unit 110 at the same position in the display chain, and the control device is connected with each dual decoding processing unit 120.
The control device binds and stores the auxiliary signal port of each double-decoding processing unit 120 in the decoding processing node chain with the main signal port of the next double-decoding processing unit 120; the control device controls each dual decoding processing unit 120 to control the corresponding display unit 110 to display images through the main signal port, and when detecting that the main signal port of the dual decoding processing unit 120 fails, controls the auxiliary signal port of the dual decoding processing unit 120 bound with the failed main signal port to control the corresponding display unit 110 to display images.
Specifically, the specific number of the display units 110 is not exclusive, and may be two or more, for example, 4, 9, 16, etc., as long as the array arrangement is possible, and the array arrangement of the plurality of display units 110 may be used as a tiled screen or a plurality of single screens for image display. For ease of understanding, the display unit 110 is used to form a tiled display screen for illustration. The type of the display unit 110 is not exclusive, and may be an LCD display unit or an LED (Light Emitting Diode) display unit, etc. The spatial position relationship between the dual decoding processing unit 120 and the display unit 110 is not unique, and in the embodiment, the dual decoding processing unit 120 is disposed around the array formed by the display units 110, so as to facilitate the connection and reduce the operation complexity.
The display units 110 form a display chain according to the principle that every two are closest to each other, that is, adjacent display units 110 are sequentially divided according to the physical positions of the display units 110 to form a virtual display chain, and each display unit 110 is used as a node in the virtual display chain. The specific manner of dividing the display units 110 into display chains is not unique, as long as it is satisfied that the physical locations of adjacent display units on the virtual display chain cannot be too far away for construction. Specifically, the display units 110 may be divided into display chains in a serpentine shape, a wavy line in a horizontal direction, or a wavy line in a vertical direction. In fig. 1 to 3, the display units 110 are divided in a serpentine manner to form a display chain, wherein numerals 1 to 16 in fig. 2 and numerals 1 to 4 in fig. 3 indicate the dividing sequence of the display units 110. Fig. 4 is a display chain formed by dividing the display units 110 according to a wavy line in the horizontal direction, and numerals 1 to 15 indicate the dividing sequence of the display units 110. Fig. 5 is a display chain formed by dividing the display units 110 in a wavy line manner in the vertical direction, and numerals 1 to 12 indicate the dividing sequence of the display units 110. In this embodiment, the display unit 110 is divided into display chains in a snake-shaped manner, so that the minimum head and tail nodes of the display chains in any dimensionality of the spliced screen can be ensured, and the connection operation is facilitated.
The dual decoding processing units 120 form a decoding processing node chain, specifically, a decoding processing node chain is established according to the established virtual display chain in combination with the physical positions of the dual decoding processing units 120, and each dual decoding processing unit 120 serves as a node in the decoding processing node chain. The same positions of the dual decoding processing units 120 in the decoding processing node chain and the display units 110 in the display chain indicate that the sequence numbers in the decoding processing node chain and the display chain are the same, for example, the dual decoding processing units 120 in the decoding processing node chain are respectively labeled as 1, 2, 3, and … … according to the sequence order, the display units 110 in the display chain are respectively labeled as 1, 2, 3, and … … according to the sequence order, then the dual decoding processing unit 120 labeled as 1 and the display unit 110 labeled as 1 can understand the same positions, the dual decoding processing unit 120 labeled as 2 and the display unit 110 labeled as 2 can understand the same positions, and so on. According to the positions of the dual decoding processing unit 120 and the display unit 110 in the corresponding links, the main signal port of the dual decoding processing unit 120 is connected to the main input interface of the display unit 110 at the same position in the display chain, and the auxiliary signal port of the dual decoding processing unit 120 is connected to the auxiliary input interface of the display unit 110 next to the display unit 110 at the same position in the display chain. It can be understood that the connection of the auxiliary signal port of the dual decoding processing unit 120 to the auxiliary input interface of the next display unit 110 of the display unit 110 at the same position in the display chain means that the connection of the auxiliary signal port of the dual decoding processing unit 120 to the auxiliary input interface of the next display unit 110 of the display unit 110 with the same sequence number in the display chain, for example, the connection of the auxiliary signal port of the dual decoding processing unit 120 labeled 1 to the auxiliary input interface of the display unit 110 labeled 2 in the display chain.
For convenience of description, the channel and the input port of each node may be numbered, the main channel (i.e., the main signal port of the dual decoding processing unit 120) is x.0, the backup channel (i.e., the auxiliary signal port of the dual decoding processing unit 120) is x.1, the main input port (i.e., the main input interface of the display unit 110) is x.0, and the auxiliary input port (i.e., the auxiliary input interface of the display unit 110) is x.1, where x is the node number of the display chain or the decoding processing node chain, starting with 1. Taking the 2x2 tiled screen shown in fig. 6 as an example, the display elements 110 are divided into display chains in a serpentine fashion in a clockwise direction. The display unit 110 is an LCD unit, which is respectively marked as LCD-1, LCD-2, LCD-3 and LCD-4. The double decoding processing units 120 in the decoding processing node chain are respectively marked as a double decoding processing unit-1, a double decoding processing unit-2, a double decoding processing unit-3 and a double decoding processing unit-4. The main channel 1.0 of the double decoding processing unit-1 is connected with the main input port 1.0 of the LCD-1, the main channel 2.0 of the double decoding processing unit-2 is connected with the main input port 2.0 of the LCD-2, and the rest is done in turn to complete the main display connection. The auxiliary channel 1.1 of the double decoding processing unit-1 is connected with the auxiliary input interface 2.1 of the LCD-2, the auxiliary channel 2.1 of the double decoding processing unit-2 is connected with the auxiliary input interface 3.1 of the LCD-3, and the backup display connection is completed by analogy in sequence. The control device manages the channels of the decoding processing nodes, an auxiliary channel 1.1 of the double decoding processing unit-1 is bound with a main channel 2.0 of the double decoding processing unit-2, an auxiliary channel 2.1 of the double decoding processing unit-2 is bound with a main channel 3.0 of the double decoding processing unit-3, the channels connected to the same LCD are bound by analogy in sequence, the same streaming media source windowing information is issued to the bound channels in real time, and once any node fails, the bound backup channels are started immediately.
According to the distributed display device, the main signal port and the auxiliary signal port of the double-decoding processing unit 120 in the decoding processing node chain are connected with the main input interface and the auxiliary input interface of the corresponding display unit 110, and the binding relationship of the main signal port and the auxiliary signal port is established, so that the chain type double-channel display backup binding is realized, and the manufacturing cost of the distributed display device is reduced. In addition, the method can be used as a reference basis for unifying backup modes of the dual-channel display backup system, so that the situation that various backup scenes cannot be dealt with by adopting a universal logic is avoided, and the construction and program implementation complexity is reduced.
In one embodiment, the auxiliary input interface of the head-end display unit 110 in the display chain is connected to the auxiliary signal port of the end dual decode processing unit 110 in the chain of decode processing nodes. The control device also binds and stores the main signal port of the head-end double decoding processing unit 120 and the auxiliary signal port of the tail-end double decoding processing unit 120 in the decoding processing node chain.
The head end display unit 110 is a display unit arranged at the head in the display chain, the head end double decoding processing unit 120 is a double decoding processing unit arranged at the head in the decoding processing node chain, and the tail end double decoding processing unit 120 is a double decoding processing unit arranged at the tail in the decoding processing node chain. Similarly, taking fig. 6 as an example, the auxiliary input port 1.1 of the LCD-1 is connected to the auxiliary channel 4.1 of the dual decoding processing unit-4, and the control device binds and stores the main channel 1.0 and the auxiliary channel 4.1 connected to the LCD-1, so that each LCD corresponds to the main channel and the auxiliary channel, thereby forming a chain type cyclic backup. Once any node fails, the backup channel of the adjacent node in the anticlockwise direction is started immediately, and the operation reliability of the distributed display equipment is improved.
In another embodiment, the distributed display apparatus further includes an auxiliary decoding processing unit, and the auxiliary input interface of the head end display unit 110 in the display chain is connected to the signal port of the auxiliary decoding processing unit. The control device also binds and stores the signal port of the auxiliary decoding processing unit with the main signal port of the head-end double decoding processing unit 120 in the decoding processing node chain.
The auxiliary decoding processing unit can adopt a single-channel decoding processing unit, and the auxiliary decoding processing unit can also be understood as an auxiliary decoding processing node which is additionally arranged at the tail end of the decoding processing node chain. The double-channel backup of the head-end display unit 110 in the display chain is realized by adding the auxiliary decoding processing unit, the problem that the connection difficulty is increased due to the fact that the physical position distance of the head-end display unit and the tail-end display unit of the display chain is too far is avoided, and the convenience of connection operation is improved. Also taking fig. 6 as an example, if the physical positions of the head and tail display units of the display chain are too far away, and the backup channel of the tail decoding processing unit cannot be connected to the auxiliary input port of the head display unit, an additional auxiliary decoding processing node n needs to be added to connect its channel (i.e. signal port) n.1 to the auxiliary input port 1.1 of the LCD-1. The control device binds the channel n.1 of the auxiliary decoding processing node with the main channel 1.0 of the double decoding processing unit-1, and chain type circulating backup can be realized.
Further, in an embodiment, the control device is further configured to output an alarm message when detecting that the auxiliary signal port of the dual decoding processing unit 120 or the signal port of the auxiliary decoding processing unit has a fault. The additional auxiliary decode processing node is also managed as one node on the decode processing node chain. If the main channel of the decoding processing node fails, the auxiliary channel corresponding to the decoding processing node or the channel of the auxiliary decoding processing node is started, and if the auxiliary channel of the decoding processing node or the channel of the auxiliary decoding processing node fails, only an alarm is sent out, and no backup strategy logic processing can be carried out. The mode of outputting the alarm information is not unique, and the alarm information can be given by controlling the alarm lamp to flash, or the speaker to sound, or the display to display the preset picture or character information, or at least two of the three modes.
In combination with the above two embodiments of the circular chain backup, the LCD display units form a virtual LCD chain as an example, and so on, the virtual LCD chain with the total number of LCD display units being c has a node number of x (1, 2, 3,. and.. c), and the node number of the corresponding decoding processing node chain is y (1, 2, 3,. and.. c, or 1, 2, 3,. and.. c, and c +1, where the node c +1 is a possible auxiliary decoding processing node). The decode processing node y.0 channel for x equal to y is connected to the lcdx.0 input port, the decode processing node y.1 channel for x equal to y +1 is connected to the lcdx.1 input port, and the decode processing node y.1 channel for y equal to c or c +1 is connected to the LCD1.1 input port. The control device binds the y.1 channel with the [ y +1] 0 channel, and binds the c.1 or [ c +1] 1 channel with the 1.0 channel. Once any node fails, the backup channel of the adjacent node in the anticlockwise direction is started immediately, and then failure recovery can be achieved. And the chain type circulating backup is realized based on the number of decoding processing nodes which is the same as or one more than that of the LCD nodes, so that a display backup system capable of restoring any non-adjacent node fault is realized.
In one embodiment, a method for generating a node backup scheme of a distributed display device is provided, which is suitable for performing display backup on a spliced screen. As shown in fig. 7, the method comprises the steps of:
step S110: and forming a display chain by the plurality of display units arranged in the array according to the principle that every two display units are nearest to each other.
The specific number of the display units is not unique, and the plurality of display unit arrays can be arranged to be used as a spliced screen or a plurality of single screens for image display. For the sake of understanding, the following explanation is made by taking the display units as an example to constitute a tiled screen. The display unit may be an LCD display unit or an LED display unit, etc. In this embodiment, the dual decoding processing units are arranged around the array formed by the display units, so as to facilitate the connection and reduce the operation complexity.
Specifically, the display unit can be combined into a display chain according to the principle that every two display units are closest to each other through the upper computer, and the upper computer can be a desktop computer, a single chip microcomputer and the like. The upper computer divides the display units into display chains according to the principle that every two display units are closest to each other, namely, the adjacent display units are sequentially divided according to the physical positions of the display units to form virtual display chains, and each display unit is used as a node in the virtual display chain. The display units can be divided into display chains in a serpentine manner, a wavy line in the horizontal direction or a wavy line in the vertical direction. In this embodiment, adopt snakelike mode to divide the display element and constitute the display chain, can guarantee that the head and the tail node of display chain is minimum under the arbitrary dimension of concatenation screen, is convenient for carry out the wiring operation.
Step S120: and forming a decoding processing node chain by the double decoding processing units with the same number as the display units.
The main signal port of each double decoding processing unit in the decoding processing node chain is respectively connected with the main input interface of the display unit at the same position in the display chain, and the auxiliary signal port of each double decoding processing unit is connected with the auxiliary input interface of the next display unit of the display unit at the same position in the display chain. The upper computer enables the double decoding processing units to form a decoding processing node chain, specifically, the decoding processing node chain is established according to the established virtual display chain and in combination with the physical positions of the double decoding processing units, and each double decoding processing unit is used as a node in the decoding processing node chain. The same positions of the double decoding processing units in the decoding processing node chain and the display units in the display chain mean that the arrangement sequence numbers in the decoding processing node chain and the display chain are the same. According to the positions of the double decoding processing unit and the display unit in the corresponding link, respectively establishing a connection relationship between a main signal port of the double decoding processing unit and a main input interface of the display unit at the same position in the display chain, and establishing a connection relationship between an auxiliary signal port of the double decoding processing unit and an auxiliary input interface of a display unit next to the display unit at the same position in the display chain.
