It is understood that the smart terminal includes a smart phone, a notebook computer, a server, and other devices having similar functions.
The LED display screen has a certain storage function, can be used for temporarily storing preset content or dynamic content, and can timely clean the storage space after the preset content or the dynamic content is displayed.
The LED display screen at least comprises two display sub-areas; it can be understood that the more the number of the display sub-regions is, the easier the complex dynamic effect is to be realized, and the control difficulty is increased, so that the number of the display sub-regions is set according to the actual situation.
The preset content in the application refers to display content in a pre-plan, and can be used for static display and dynamic display, wherein the dynamic display is not consistent with the dynamic content, the dynamic content in the application essentially refers to display content which is distinguished from the preset content, and the dynamic content refers to display content which is temporarily acquired according to actual requirements.
In one embodiment, the remote control terminal generates and transmits the preset content to the LED display screen, including:
the remote control terminal generates preset content;
and checking the preset content, and after the checking is successful, adjusting and dividing the preset content by combining the display sub-area with the display rule.
The method mainly aims to generate preset content in advance through a remote control terminal, and after verification, an LED display screen displays the preset content according to the arrangement of display time; it can be understood that there is a time synchronization device between the remote control terminal and the LED display screen to ensure time synchronization between the remote control terminal and the LED display screen, and the display time is set when the preset content or the dynamic content is generated.

In a specific embodiment, the display rule determines the display parameters and the display type of the preset content or the dynamic content in the LED display screen.
The display rule of the embodiment can be set in the storage space of the LED display screen, and can be set according to the preset content or the dynamic content, mainly to ensure the content display effect. It is understood that the display rules may also include two types, one type is stored in the LED display screen storage space, and the other type is set according to the preset content or the dynamic content, but the priority of the display rule corresponding to the latter type is higher than that of the former type.
The display parameters in this embodiment include a display size and a display position, and determine the size and the position of the preset content or the display content in the LED display screen and each display sub-area, and the final purpose of the display parameters is to ensure the display effect.
In one embodiment, the remote control terminal acquires dynamic content based on preset content, including:
extracting preset content and generating a backup file of the preset content;
extracting a region to be modified according to the corresponding relation between the preset content and the display sub-region;
and modifying the area to be modified to obtain the dynamic content.
The main purpose in this embodiment is to implement isolated modification of the preset content, where the isolated modification refers to modifying the preset content on the basis of not affecting the playing of the preset content, and acquiring the dynamic content.
In this embodiment, when the preset content is displayed on the LED display screen, a corresponding relationship is generated with each display sub-area (related data is generated in the adjustment and division of the preset content), and a display sub-area corresponding to the content to be modified is selected, so that the area to be modified can be obtained.

It can be understood that the above two schemes can be flexibly applied according to actual situations, for example, when the modified content is more, the modified content is merged with the unmodified content to generate the dynamic content, and when the modified content is less, the modified content is marked as the dynamic content separately.
In a specific embodiment, after receiving the dynamic content, the LED display screen obtains the display time set in the dynamic content, and switches the preset content into the dynamic content according to the display time.
In this embodiment, the display time mainly includes a display time, and in some cases, also includes a display duration; in other preferred embodiments, the display time may be set separately from the dynamic content.
In one embodiment, the remote control terminal monitors the fault of the LED display screen, and the method includes:
sequentially selecting display sub-areas and marking the display sub-areas as target areas;

when a faulty LED exists in the target area, the target area is marked as a faulty area.
When the fault detection is performed on the LED in this embodiment, factors such as current, voltage, and temperature may be mainly considered, for example:
the temperature of the LED is obtained, and when the temperature is higher than a temperature threshold value, the LED can be judged to be in fault.
A mixture of factors may also be considered, such as:
and acquiring the temperature and the voltage of the LED, and judging that the LED breaks down when the temperature and the voltage are both greater than corresponding threshold values.
In some cases, it is not necessary to detect the failure of all the LEDs in the target sub-area, but it is sufficient to detect the failure of some LEDs, for example:
uniformly selecting a plurality of LEDs from a target area, and carrying out fault detection on the selected LEDs so as to obtain a fault area; it will be appreciated that when the number of LED LEDs is large, individual failed LED LEDs will not cause the corresponding target area to be marked as a failed area.
Double fault detection may also be performed to reduce data throughput, such as:
acquiring a region with higher temperature through a temperature sensor, and carrying out fault detection on the LED in the region; or
And acquiring the LED light-emitting diodes with the current values out of the normal range through the current sensor, and carrying out fault detection on the LED light-emitting diodes.
In a specific embodiment, the LED display screen is divided in real time according to the fault monitoring result, and the fault area does not participate in displaying preset content or dynamic content in the dividing process.
The main purpose of this embodiment is to ensure that the fault area does not affect the display of the preset content or the dynamic content, such as:
when the upper left corner is a fault area, the display area of the LED display screen is reduced to avoid the fault area;
and when the center is a fault area, judging whether the fault area works when the preset content or the dynamic content is displayed, and if the area does not work, not processing the fault area.
It can be understood that when the LED display screen has a fault area, a fault signal should be fed back in time so that a worker can process the fault signal in time.
Part of data in the formula is obtained by removing dimension and taking the value to calculate, and the formula is obtained by simulating a large amount of collected data through software and is closest to a real situation; the preset parameters and the preset threshold values in the formula are set by those skilled in the art according to actual conditions or obtained through simulation of a large amount of data.
