The LED display screen is easily damaged under high humidity. In order to improve the service life of the LED display screen, an embodiment of the present application provides a method for dehumidifying an LED display screen. Referring to FIG. 1, the method includes:

S101. Determine whether the LED display meets a preset dehumidification trigger condition.

The dehumidification system may also be a storage medium for storing executable code, and the executable code is used to execute the method for dehumidifying the LED display screen in the embodiment of the present application.

The preset dehumidification triggering conditions may be set according to actual conditions, and may include, for example, starting dehumidification when the target time is reached, turning on dehumidification when it is turned on, receiving a dehumidification start instruction, or an environmental parameter reaching a preset parameter threshold. You can establish a specified thread to monitor whether a predetermined dehumidification trigger condition is met, for example, to monitor whether an environmental parameter reaches a preset parameter threshold by specifying a thread; you can also actively trigger dehumidification when the LED display meets a preset dehumidification trigger condition, such as an LED display Actively trigger dehumidification after booting. The environmental parameters may include the humidity of the LED display, and may also include the temperature of the LED display. The environmental parameters reaching the preset parameter threshold may be the humidity of the LED display reaching the humidity threshold.

S102. Dehumidify the LED display screen when the LED display screen meets the preset dehumidification triggering condition.

For example, you can install a heating wire in the LED display in advance, and the dehumidification system starts the heating wire in the LED display to dehumidify; or you can install an exhaust fan in the LED display in advance, and the dehumidification system starts the exhaust fan in the LED display to perform dehumidification; or dehumidification The system is externally air-conditioned to dehumidify the LED display. LED display with different dehumidification devices can set different dehumidification time and frequency.

In a possible implementation manner, the dehumidifying the LED display screen includes: gradually increasing the brightness of the LED display screen according to a preset brightness enhancement rule to achieve dehumidification of the LED display screen.

When the lamp beads in the LED display light up, heat will be generated.

For different target parameter thresholds, different brightness enhancement rules can be set, that is, different brightness of the lamp beads and the time for maintaining each brightness. Gradually increase the brightness of the lamp beads in the LED display to reduce the humidity of the LED display.

The brightness enhancement rule can be summarized as follows: Set the initial brightness of each lamp bead in the LED display as LightStart, set the end brightness to LightEnd, divide the brightness into n levels, and increase the step size of the brightness to StepL. Each brightness level The hold time is T.

For example, the initial brightness is 10% for 2 hours, then the brightness is maintained at 20% for 2 hours, and then the brightness is maintained at 30% for 2 hours, and so on until the end of the brightness for 2 hours After that, restore the brightness to the brightness before dehumidification, that is, the brightness used normally.

The total dehumidification time can be set according to the actual situation. The setting principle can be that the lower the moisture level of the LED display, the less the total dehumidification time, the higher the humidity of the LED display, and the longer the total dehumidification time. The LED display screen is less affected by humidity when the brightness of the lamp beads is low. By gradually increasing the brightness, the LED screen can be effectively dehumidified while reducing the damage to the LED display screen without increasing the heating wire or air conditioner. And other dehumidification equipment, saving costs.

In the embodiment of the present application, when the LED display screen meets a preset dehumidification triggering condition, dehumidifying the LED display screen can realize automatic dehumidification of the LED display screen and increase the service life of the LED display screen.

In a possible implementation manner, the method for dehumidifying an LED display screen in the embodiment of the present application further includes: after obtaining the dehumidification start setting instruction, setting the preset dehumidification triggering condition according to the dehumidification startup setting instruction.

The dehumidification start setting instruction is used to set a trigger condition for starting dehumidification. This trigger condition can be set according to the actual situation, such as triggering dehumidification every time the power is turned on, triggering dehumidification before each power off, triggering the dehumidification according to a set time period or a set time.

In a possible implementation manner, the above-mentioned preset dehumidification triggering condition includes starting dehumidification when the target time is reached; the above-mentioned determining whether the LED display screen meets the preset dehumidification triggering condition includes: determining whether the system clock of the LED display screen reaches the above-mentioned target time ;

When the LED display screen meets the preset dehumidification triggering condition, the dehumidifying the LED display screen includes: dehumidifying the LED display screen when a system clock of the LED display screen reaches the target time.

The target time can be a user-defined time or a time provided by the server background. For example, the target time can be set to twelve o'clock on the 1st of each month, or the target time can be set to a target time every 200 hours. Wait.

In a possible implementation manner, the above-mentioned preset dehumidification triggering condition includes power-on dehumidification; the above-mentioned determining whether the LED display screen meets the preset dehumidification triggering condition includes: determining whether the LED display screen is successfully turned on;

When the LED display screen meets the preset dehumidification triggering condition, the dehumidifying the LED display screen includes: dehumidifying the LED display screen after the LED display screen is successfully turned on.

In a possible implementation manner, the above-mentioned preset dehumidification trigger condition includes receiving a dehumidification start instruction; the above-mentioned determining whether the LED display screen meets the preset dehumidification trigger condition includes: determining whether the LED display screen is full and receives a dehumidification start sent by a remote device instruction;

When the LED display screen meets the preset dehumidification triggering condition, the dehumidifying the LED display screen includes dehumidifying the LED display screen after the LED display screen receives a dehumidification start instruction sent by a remote device.

The remote device can be a client device such as a smartphone or a personal computer, or a server device.

In a possible implementation manner, the above-mentioned preset dehumidification triggering condition includes that the environmental parameter of the LED display reaches a preset parameter threshold; the above-mentioned determining whether the LED display meets the preset dehumidification triggering condition includes determining the environment of the LED display The parameter reaches a preset parameter threshold;

When the LED display screen meets the preset dehumidification triggering condition, the dehumidifying the LED display screen includes dehumidifying the LED display screen when an environmental parameter of the LED display screen reaches a preset parameter threshold.

The environmental parameters may include the environmental humidity of the LED display, and the environmental parameters reaching the preset parameter threshold may be that the environmental humidity of the LED display is greater than or equal to the humidity threshold. The environmental parameters may also include the ambient temperature of the LED display. The ambient temperature and humidity here can be the average temperature and average humidity per unit time. The ambient temperature can be obtained through a temperature sensor, and the ambient humidity can be obtained through a humidity sensor. Optionally, different humidity thresholds can be set for different ambient temperatures. For example, the ambient temperature is divided into multiple temperature intervals in advance, and each temperature interval corresponds to a corresponding humidity threshold. At this time, the environmental parameters of the LED display screen reach a predetermined level. Setting the parameter threshold includes: determining the temperature interval to which the ambient temperature in the environmental parameter belongs; determining the humidity threshold corresponding to the temperature interval; and determining the LED display when the environmental humidity in the environmental parameter is greater than or equal to the humidity threshold corresponding to the temperature interval The environmental parameters reach a preset parameter threshold.

In the embodiment of the present application, when the LED display screen meets the preset dehumidification triggering condition, dehumidifying the LED display screen can realize dehumidification of the LED display screen and increase the service life of the LED display screen.

In a possible implementation manner, referring to FIG. 2, the foregoing determining whether the LED display screen meets a preset dehumidification triggering condition includes:

S201. Obtain the shutdown time parameter of the LED display.

The dehumidification system obtains the off-time parameter of the LED display, and the off-time parameter represents the length of time that the LED display is off. For example, the shutdown time parameter may include the proportion of shutdown time in a unit time, and / or the shutdown time from the last shutdown time. Optionally, in order to ensure the acquisition of the shutdown time parameter, the dehumidification system records the startup time and shutdown time of the LED display.

S202: Determine whether the shutdown time parameter is greater than a target parameter threshold.

The target parameter threshold can be an empirical value. The setting of the specific value is related to the temperature and humidity of the LED display environment. The higher the temperature and humidity, the smaller the target parameter threshold. If the shutdown time parameter is greater than the target parameter threshold, it is considered that the ambient humidity of the LED display will adversely affect the service life of the LED display, so the LED display needs to be dehumidified. If the shutdown time parameter is not greater than the target parameter threshold, it is considered that the environmental humidity of the LED display is insufficient to adversely affect the service life of the LED display, so there is no need to dehumidify the LED display.

S203. If the shutdown time parameter is greater than the target parameter threshold, dehumidify the LED display screen.

When the shutdown time parameter is greater than the target parameter threshold, the dehumidification system dehumidifies the LED display. For example, a heating wire can be installed in the LED display in advance, and the dehumidification system starts the heating wire in the LED display to dehumidify; An exhaust fan is installed in the screen in advance, and the dehumidification system starts the exhaust fan of the LED display screen to perform dehumidification; or the dehumidification system is connected to an external air conditioning device to dehumidify the LED display screen. LED display with different dehumidification devices can set different dehumidification time and frequency.

If the shutdown time parameter is greater than the target parameter threshold value, the brightness of the LED display screen is gradually increased according to a preset brightness enhancement rule to achieve dehumidification of the LED display screen.

The total dehumidification time is set according to the shutdown time parameter and the target parameter threshold. The setting principle is that the total dehumidification time is positively related to the shutdown time parameter, and the total dehumidification time is negatively related to the target parameter threshold, which can be understood as the lower the humidity of the LED display, the less the total time of the dehumidification, and the higher the humidity of the LED display. The longer the total dehumidification time. The LED display screen is less affected by humidity when the brightness of the lamp beads is low. By gradually increasing the brightness, the LED screen can be effectively dehumidified while reducing the damage to the LED display screen without increasing the heating wire or air conditioner. And other dehumidification equipment, saving costs.

In the embodiment of the present application, when the shutdown time parameter is greater than the target parameter threshold, dehumidifying the LED display screen can realize automatic dehumidification of the LED display screen and increase the service life of the LED display screen.

Optionally, before determining whether the shutdown time parameter is greater than a target parameter threshold, the method further includes:

Step 1: Obtain the ambient temperature and ambient humidity of the environment in which the LED display is located.

The dehumidification system obtains the ambient temperature and ambient humidity of the environment where the LED display is located. The ambient temperature and ambient humidity here can be the average temperature and average humidity in a unit time. The dehumidification system can obtain the ambient temperature through a temperature sensor and the ambient humidity through a humidity sensor.

Step 2: Determine the above-mentioned ambient temperature and the parameter threshold corresponding to the above-mentioned ambient humidity according to the corresponding relationship between the temperature, humidity, and the parameter threshold, and obtain the target parameter threshold.

The parameter threshold is an empirical value measured experimentally. The specific value is related to temperature and humidity. Temperature is negatively related to the parameter threshold, and humidity is negatively related to the parameter threshold. The corresponding relationship between the temperature and humidity and the parameter threshold is set in advance. For example, the temperature and humidity are divided into multiple intervals, and each interval corresponds to the parameter threshold. According to the corresponding relationship, the dehumidification system determines a parameter threshold corresponding to both the ambient temperature and the ambient humidity as the target parameter threshold.

In the embodiment of the present application, the target parameter threshold is determined according to the ambient temperature and the ambient humidity. The target parameter threshold is more reasonable, and can satisfy the dehumidification of the LED display screens in different humidity regions and different damp conditions.

Optionally, the shutdown time parameter includes a shutdown duration ratio of a shutdown time per unit time, and the target parameter threshold includes a target duration ratio threshold.

The unit time can be set according to the actual situation, such as 5 days, 7 days, or 10 days. When the shutdown duration ratio is greater than the target duration percentage threshold, it is determined that the shutdown time parameter is greater than the target parameter threshold.

For example, the dehumidification system can use T days as the unit time. The dehumidification system records the lighting time of the LED display every day. The screen can be turned on and off multiple times in a day. Each group of data records the total number of days when the LED display is turned on. time. Determine the proportion of the LED display off time in T days. The total length of time that the LED display is lit is T1, which is the cumulative time of each day in T days, and the total time that is turned off is T-T1. The percentage of shutdown time can be expressed as (T-T1) / T. The longer the total required dehumidification time.

Optionally, the shutdown time parameter includes a shutdown time from a last shutdown time, and the target parameter threshold includes a target duration threshold.

The moisture of the LED display occurs when the LED display is turned off. When the dehumidification system is turned on, check the last shutdown time. Detect whether the LED display shutdown time reaches the target duration threshold to determine whether dehumidification is required. The longer the shutdown time, the longer the total dehumidification time required. When the shutdown time is greater than the target duration threshold, it is determined that the shutdown time parameter is greater than the target parameter threshold.

Optionally, when the shutdown time parameter includes the shutdown duration and the shutdown duration ratio, and the target parameter threshold includes the target duration threshold and the target duration ratio threshold, when the shutdown duration is greater than the target duration threshold and / or the shutdown duration ratio When it is larger than the target duration ratio threshold, it is determined that the shutdown time parameter is greater than the target parameter threshold.

Optionally, the shutdown time parameter includes a valid shutdown duration, and the target parameter threshold includes a target duration threshold;

The corresponding method for dehumidifying the LED display in the embodiment of the present application further includes:

Step 1: Record the start-up time and shutdown time of the LED display.

The dehumidification system records each time the LED display is turned on and off.

Step 2: Determine the startup time of the LED display each time according to each of the above startup times and each of the shutdown times.

In step three, a shutdown time corresponding to a startup time longer than a preset startup threshold is taken as an effective shutdown time.

The preset power-on threshold can be set according to actual conditions, for example, 15 minutes, 30 minutes, or 1 hour.

Step 4: Determine the length of time between the latest power-on time and the last effective power-off time to obtain the effective power-off time.

In order to prevent the detected shutdown time due to the short startup time, which cannot characterize the moisture condition of the LED display, it is necessary to rule out the shorter startup time. For example, as shown in FIG. 3, the power-on and power-off conditions are recorded over a period of time, including power-on 1, power-off 1, power-on 2, power-off 2, power-on 3, power-off 3, and power-on 4, A longer lateral distance means a longer time interval. The power-on time between power-on 3 and power-off 3 is less than the preset power-on threshold, so the time between power-on 4 and power-off 2 is calculated as the effective shutdown time.

Optionally, the method for dehumidifying an LED display screen according to the embodiment of the present application further includes:

Step 1. Obtain a dehumidification instruction.

The dehumidification system obtains a dehumidification instruction input by a user. The dehumidification instruction may include dehumidification parameters. Dehumidification parameters are various setting parameters during the dehumidification process of the LED display. For example, the dehumidification parameters may include an initial brightness of the LED display screen, LightStart, an end brightness of LightEnd, an increase in brightness level n, a brightness step StepL, and a time T for maintaining each brightness level.

Step 2: Dehumidify the LED display screen according to the dehumidification instruction.

The dehumidification system triggers the dehumidification of the LED display screen through the dehumidification instruction. The dehumidification process can be set in advance. When the dehumidification command is included in the dehumidification command, the dehumidification system dehumidifies the LED display according to the dehumidification parameter.

In the embodiment of the present application, the LED display screen is dehumidified according to the dehumidification instruction, and the dehumidification can be controlled manually.

Optionally, referring to FIG. 4, the method for dehumidifying an LED display screen of the embodiment of the present application is also applicable to a splicing screen formed by splicing multiple LED displays.
