It is understood that smart terminals include smartphones, notebook computers, servers, and other devices with similar functionality.
The LED display screen has a certain storage function, can be used for temporarily storing preset contents or dynamic contents, and can timely clear the storage space after the preset contents or dynamic contents are displayed.
The LED display screen at least comprises two display subareas; it can be understood that the more the number of the display subareas is, the easier the complex dynamic effect is realized, and the control difficulty is increased at the same time, so that the number of the display subareas is set according to the actual situation.
The preset content in the application refers to display content in a preset program, and the preset content can be used for static display and dynamic display, wherein the dynamic display is inconsistent with the dynamic content, the dynamic content in the application substantially refers to display content which is different 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 preset content to the LED display screen, including:

In a specific embodiment, the display rules determine the display parameters and display types of the preset content or dynamic content in the LED display screen.
The display rule of the embodiment can be built in the storage space of the LED display screen, and can be set according to preset content or dynamic content, mainly to ensure the content display effect. It will be appreciated that the display rules may also include two types, one stored in the LED display screen storage space and one set according to preset content or dynamic content, but the priority of the display rules corresponding to the latter is higher than that of the former.
The display parameters in this embodiment include a display size and a display position, which 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 is to ensure the display effect.
In one embodiment, the remote control terminal obtains 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 dynamic content.
The main purpose of this embodiment is to implement the isolation modification of the preset content, where the isolation modification refers to modifying the preset content to obtain the dynamic content on the basis that the play of the preset content is not affected.
In this embodiment, when the preset content is displayed on the LED display screen, a corresponding relationship is defined between the preset content and each display sub-area (related data is already generated in the adjustment and division of the preset content), and the display sub-area corresponding to the content to be modified is selected, so that the region to be modified can be obtained.

It can be understood that the above two schemes can be flexibly applied according to practical situations, for example, when the modified content is more, the modified content is combined with the unmodified content to generate the dynamic content, and when the modified content is less, the modified content is individually marked as the dynamic content.
In a specific embodiment, after the LED display screen receives the dynamic content, the display time set in the dynamic content is obtained, and the preset content is switched to 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 also be set separately from the dynamic content.
In one embodiment, the remote control terminal performs fault monitoring on the LED display screen, including:
sequentially selecting display subareas and marking the display subareas as target areas;

when there is a failed LED in the target area, then the target area is marked as a failed area.
In this embodiment, when the LED is fault-detected, factors such as current, voltage, and temperature of the LED may be mainly considered, for example:
and acquiring the temperature of the LED, and judging that the LED fails when the temperature is higher than a temperature threshold value.
Various factors may also be mixed into consideration, such as:
and acquiring the temperature and the voltage of the LED, and judging that the LED fails when the temperature and the voltage are both greater than the corresponding threshold values.
In some cases, it is not necessary to perform fault detection on all the LED light emitting diodes in the target sub-area, but only some of the LED light emitting diodes may perform fault detection, for example:
uniformly selecting a plurality of LED light emitting diodes from the target area, and performing fault detection on the selected LED light emitting diodes to further obtain a fault area; it will be appreciated that when the number of LED light emitting diodes is large, individual failed LED light emitting diodes will not have the corresponding target area 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 detecting faults of the LED in the region; or alternatively
And acquiring LED light emitting diodes with current values not in a normal range through a current sensor, and detecting faults of 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 in the dividing process, the fault area does not participate in displaying the preset content or the dynamic content.
The main purpose of this embodiment is to ensure that the fault area does not affect the display of preset content or dynamic content, such as:
when the upper left corner is a fault area, the display area of the LED display screen is reduced so as to avoid the fault area;
and when the center is a fault area, judging whether the preset content or the dynamic content works or not when the preset content or the dynamic content is displayed, and if the fault area does not work, not processing the fault area.
It can be appreciated 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 in time.
The partial data in the formula are all obtained by removing dimension and taking the numerical value for calculation, and the formula is a formula closest to the real situation obtained by simulating a large amount of collected data through software; the preset parameters and the preset threshold values in the formula are set by those skilled in the art according to actual conditions or are obtained through mass data simulation.
