The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Referring to fig. 1, a schematic structural diagram of a first LED mesh loop backup system according to an embodiment of the present invention is shown, where each LED box in the LED mesh loop backup system is correspondingly provided with a receiving card, each receiving card includes at least 3 network transceiving interfaces, so that each LED box is connected with each adjacent LED box through the network transceiving interfaces to form the mesh loop backup system, 4 transmitting cards are respectively connected with the LED boxes at 4 corners, that is, the receiving cards arranged on the 4 LED boxes at the upper left corner, the upper right corner, the lower left corner, and the lower right corner are respectively connected with one transmitting card, and each transmitting card is connected with upper computer software.
In implementation, the network transceiving interface may adopt a gigabit network port; and wireless network transceiving interfaces, such as an infrared network transceiving interface, a bluetooth network transceiving interface, and the like, can be adopted in order to reduce the wiring process.
The user sends the video data to be displayed to each sending card through the upper computer software, each sending card forwards the video data to the receiving card connected with the sending card, and the video data are transmitted among the LED box bodies through the network transceiving interfaces on the receiving cards.
In implementation, the data transmission quality of each network transceiving interface on the LED box can be detected in advance, and priorities are assigned to each network transceiving interface according to the data transmission quality, where the higher the data transmission quality is, the higher the priority is, for example, the higher the upper limit of the data transmission amount per second is; the network transceiving interface with the highest priority is used as a default network transceiving interface, and other network transceiving interfaces are used as backup network transceiving interfaces;
in the video transmission process, the video data transmission condition of a current network transceiving interface which is used for transmitting video data currently in the LED box body can be monitored, and under the condition that the network transceiving interface is not switched, the current network transceiving interface is a default network transceiving interface, so that the data transmission performance of the current network transceiving interface is obtained; monitoring the average data transmission performance of the current network transceiving interface within a preset time under the condition that the data transmission performance is not within a preset performance index range; under the condition that the average data transmission performance is not within the range of the preset performance index, selecting a target network transceiving interface from backup network transceiving interfaces, wherein the backup network transceiving interfaces are network transceiving interfaces in the LED box body except the current network transceiving interface; the current network transceiving interface is switched to the target network transceiving interface, so that the LED box body transmits the video data through the target network transceiving interface, the abnormal network transceiving interface is cut off when the current network transceiving interface in the LED box body is abnormal, the backup network transceiving interface is switched to transmit the video data, and the video data are transmitted stably and reliably between the LED box bodies.
Referring to fig. 2, a schematic flow chart of a data backup transmission method provided in an embodiment of the present invention is applied to an LED mesh loop backup system, where each LED box in the LED mesh loop backup system is correspondingly provided with a receiving card, each receiving card includes at least 3 network transceiving interfaces, so that each LED box is connected with each adjacent LED box through the network transceiving interfaces to form a mesh loop backup system, and the method includes:
s200, monitoring the video data transmission condition of the current network transceiving interface for transmitting the video data in the LED box body, and obtaining the data transmission performance of the current network transceiving interface.
In an implementation, the video data transmission condition is an index that characterizes the quality of video data transmission, and for example, the video data transmission condition may include: high and low error rate.
Specifically, the total code number and the error code number of video data transmitted by the current network transceiving interface which is used for transmitting the video data currently in the LED box body in unit time can be monitored; and calculating the error rate by using the total code number and the error code number, and taking the error rate as the data transmission performance of the current network transceiving interface.
For example, the total code number and the error code number of the video data transmitted by the current network transceiving interface in each second can be detected, the error rate is obtained by calculating the proportion of the error code number to the total code number, the higher the error rate is, the worse the data transmission performance of the current network transceiving interface is, and the network transceiving interface can be switched in order to ensure the reliability of the system.
And S210, monitoring the average data transmission performance of the current network transceiving interface within a preset time length under the condition that the data transmission performance is not within the preset performance index range.
And determining a target network transceiving interface according to a preset network transceiving interface switching rule.
In implementation, when the bit error rate is used as the data transmission performance, the preset performance index range may be 0 to 0.001, that is, when the bit error rate is greater than 0.001, it may be considered that the average data transmission performance of the current network transceiving interface needs to be monitored within a preset time period.
In implementation, by means of average data transmission performance within a preset time length, the situation that the data transmission performance of the current network transceiving interface fluctuates to cause error switching can be prevented. For example, the data transmission performance of the network transceiving interface is suddenly reduced by external electromagnetic interference, and the network transceiving interface is recovered to be normal in a short time.
In the process of calculating the average data transmission performance, the preset time duration may be divided into a plurality of sub-time durations, and the average value of the data transmission performance of each sub-time duration is calculated to obtain the credential data transmission performance. For example, the preset time duration is 10 seconds, the sub-time duration is 1 second, that is, the data transmission performance of each second is respectively monitored to obtain 10 monitoring values of the data transmission performance, and then the average value of the 10 monitoring values of the data transmission performance is calculated to obtain the average data transmission performance.
And S220, under the condition that the average data transmission performance is not in the preset performance index range, selecting a target network transceiving interface from the backup network transceiving interfaces.
The backup network transceiving interface is the network transceiving interface in the LED box body except the current network transceiving interface.
After the network transceiving interfaces are determined to be switched, the preset priority of each backup network transceiving interface on the LED box body can be obtained; determining whether a backup network transceiving interface with a preset priority higher than that of a current network transceiving interface exists; if the network receiving and sending interface exists, the backup network receiving and sending interface with the preset priority higher than the current network receiving and sending interface is determined as a target network receiving and sending interface; and if the network receiving and transmitting interface does not exist, determining the backup network receiving and transmitting interface with the next level preset priority of the current network receiving and transmitting interface as the target network receiving and transmitting interface.
In implementation, under the condition that the types of the network transceiving interfaces are different, priorities can be allocated to each network transceiving interface according to the performance of the network transceiving interface, and the higher the performance is, the higher the corresponding priority is; for example, the higher the upper limit of the amount of data transmitted per second, the higher the priority of the network transceiving interface;
and in the case that the types of the network transceiving interfaces are the same, the network transceiving interfaces on each receiving card may be set with priorities according to a uniform rule, for example, in the case that the receiving card has 4 network transceiving interfaces, the 4 network transceiving interfaces are respectively disposed on one side of the LED box, and the priorities of the network transceiving interfaces may be set according to a rule that the priorities decrease in a clockwise direction from the left.
And S230, switching the current network transceiving interface to a target network transceiving interface so that the LED box body transmits video data through the target network transceiving interface.
In implementation, after the target network transceiving interface is determined, the current network transceiving interface may be disconnected, that is, the current network transceiving interface is set to be in a standby state, the target network transceiving interface is activated, and video data is transmitted through the target network transceiving interface.
In implementation, after each LED box receives the transmitted video data, the LED box may further select the target video content according to a preset video content selection rule by using a preset number of each video content in the video data, so that the LED box displays the target video content.
Specifically, a preset number of each LED box can be obtained; and selecting the target video content according to the preset number matching rule by using the preset number of each video content in the video data and the preset number of each LED box.
For example, the numbers of the video contents are 0, 1, 2 and 3 … … in sequence; the LED box bodies are numbered as 0, 1, 2 and 3 … … in sequence; therefore, the LED box body 0 selects the video content No. 0 to display, the LED box body 1 selects the video content No. 1 to display, the LED box body 2 selects the video content No. 2 to display … …, and the display of the video data is finished by the analogy.
