The following is a detailed introduction to a display screen control method provided by the present application.

Please refer to FIG. 2. FIG. 2 is a flowchart of a method for controlling a display screen according to an embodiment of the application. The display screen control method can be implemented by interaction between the client, server, and display device as shown in FIG. 1; as shown in FIG. 2, the display screen control method includes but is not limited to the following steps 201 to 203, and the method shown in FIG. Take the server as the main body as an example.

S201. Acquire display screen parameters of the display device.

A display device is a device that can output images (such as an LED display) or a device that senses information (such as a braille display designed for the blind). The display device is composed of a controller and a display screen. The display device is composed of multiple cabinets. The cabinet is a small display screen (can be a display screen of 960mm×960mm, 768mm×768mm, etc.). The larger the number of bodies, the larger the display area of the LED display screen of the spliced display device. Each cabinet also includes sensors configured to obtain the environmental conditions and operating status of the cabinet, such as temperature monitors, humidity monitors, and voltage monitors.

The controller has the functions of digital-to-analog conversion and data processing, can parse the instructions sent by the server, and realize the management of the box parameters and operating environment of each box. The controller can be controlled by an MCU (Microcontroller Unit) Device.

In one embodiment, a wireless communication network connection is established between the controller and the sensor, and the wireless communication network may be a ZigBee network. The controller receives the temperature parameters, humidity parameters, voltage parameters, current parameters, connected screen data, calibration data and other cabinet parameters monitored by the sensors through the wireless communication network. Among them, the temperature parameters represent the ambient temperature of the cabinet and the hardware temperature of the cabinet. The humidity parameter represents the air humidity inside the cabinet, and the voltage parameter represents the power supply voltage of the cabinet. For example, if the cabinet parameters are (36 degrees, 50%, 5V, 2A, there are screen parameters, no correction coefficients), it means that the current temperature parameters of the cabinet are 36 degrees, the humidity parameters are 50%, and the voltage parameters are 5V, The current parameter is 2A, the continuous screen data is with continuous screen parameters, and the calibration data is without correction coefficients.

S202: Obtain a corresponding adjustment instruction according to the display screen parameter.

In one embodiment, the server receives multiple cabinet parameters sent by the controller through the wireless communication network, and uses the multiple cabinet parameters and corresponding cabinet identifiers as the display screen parameters of the display device. Among them, the wireless communication network can be a narrowband Internet of Things (NB-IoT) network. The server sends the display screen parameters to the client, so that the user sends adjustment instructions according to the display parameters displayed on the client. The adjustment instructions carry the box that needs to be adjusted. Instruction information such as the cabinet identification corresponding to the body, the regulator identification corresponding to the regulator used for parameter adjustment, the preset time interval, and the preset parameter range.

For example, the display parameters of the display device A composed of 4 cabinets are: the cabinet with the cabinet identification (1, 1) corresponds to the cabinet parameters (36 degrees, 50%, 5V, 2A, with continuous screen) Parameter, no correction coefficient), the corresponding cabinet parameters of the cabinet with the cabinet identification (1, 2) are (34 degrees, 52%, 5V, 2A, no screen parameters, no correction coefficient), and the cabinet identification is The cabinet parameters corresponding to the cabinet of (2, 1) are (34 degrees, 49%, 4.9V, 2A, there are screen parameters, there are correction coefficients), and the cabinet marked as (2, 2) corresponds to the cabinet The cabinet parameters are (37 degrees, 48%, 4.9V, 2A, no screen parameters, no correction coefficients). The display screen parameters of the display device A can be displayed through the mini program in the social application X, and the display screen parameters of the display device A can also be displayed through the monitoring application Y.

S203: Send the adjustment instruction to the display device, so that the display device adjusts the parameters of the display screen according to the adjustment instruction.

In one embodiment, the server sends the adjustment instruction to the display device through the wireless communication network, and the controller in the display device receives the adjustment instruction and parses the adjustment instruction to obtain the box identification, Command information such as the regulator ID and preset parameter range corresponding to the regulator used for parameter adjustment. The controller adjusts the cabinet parameters corresponding to the cabinet identifier to the preset parameter range by controlling the regulator corresponding to the regulator identifier. The regulator can be an air conditioner, a fan, a cabinet power switch used to turn on or off the running state of the cabinet, a connected screen regulator used to send connected screen parameters, or a corrector used to send correction data.

For example, during the rainy season, when there are more rainy weather, the humidity inside each cabinet of the display device is relatively high, and the components in the cabinet are prone to rust and damage. At this time, the adjustment command can be: start the cabinet marked as (1, 1 ) And run for 2 hours. The controller turns on the power switch of the box identified as (1, 1) according to the control instruction to make the box run for a preset period of time (2 hours), thereby improving the inside of the box The temperature parameters, reduce the humidity parameters of the cabinet. When there are more high-temperature weather in summer, the internal components of each cabinet of the display device have high temperature, and the circuit board in the cabinet is easy to burn out. At this time, the adjustment command can be: start the No. 1 fan and turn off the cabinet. The mark is (1, 1) The power switch of the box body is 2 hours, the controller turns on the fan with the regulator identification number 1 according to the control command, cools and dissipates the inside of the box body identified as (1, 1), reduces the power supply voltage, and turns off The display function of the box body is 2 hours, which reduces the running time of the box body and reduces the temperature parameter of the box body.

In one embodiment, the adjustment instruction may also carry a preset time interval for periodically adjusting the cabinet parameters. The controller periodically automatically adjusts the cabinet parameters to the preset parameter range through the regulator. The preset time interval may be 2 Day, week, month, etc.

In one embodiment, the server receives a query instruction for querying display screen parameters sent by the client. The query instruction carries the cabinet identification of the target cabinet to be queried and the type of cabinet parameter to be queried, for example, the query instruction To: query the temperature parameters of the target cabinet with the target cabinet identification as (1, 1), (1, 2), (2, 1), (2, 2). After the controller in the display device receives the query instruction, it starts the temperature monitor, and collects the cabinet identifications (1, 1), (1, 2), (2, 1), (2, 2) through the temperature monitor For the temperature parameters of the target cabinet, the temperature monitor sends the collected temperature parameters to the controller through the wireless network (ZigBee network). The server receives the temperature parameters uploaded by the controller and sends the temperature parameters to the client.

In the above embodiment, the server obtains the display screen parameters of the display device; obtains the adjustment instructions sent by the client according to the display screen parameters; sends the adjustment instructions to the display device, so that the display device adjusts the parameters of the display screen according to the adjustment instructions. By remotely controlling each cabinet in the display screen, the management efficiency of the operating state and environmental conditions of the display screen is improved.

The following describes the display screen control method provided by this application through a complete example in conjunction with FIG. 3:

S301. Obtain display screen parameters of the display device.

The cloud platform establishes communication with the display device through the NB-IoT network to realize the sending and receiving of data. The display device consists of an LED display and its drive amplifier circuit, multiple sensors (temperature monitor, humidity monitor, voltage and current monitor, connected screen data monitor, calibration data monitor), ZigBee network module, MCU controller and power supply And other hardware components. Among them, the cabinet is a small-sized display screen, and a plurality of cabinets are spliced together to form the LED display screen of the display device. The cabinet also includes regulators (such as air conditioners, fans) for adjusting cabinet parameters.

The sensor sends the collected temperature parameters, humidity parameters, voltage parameters and other cabinet parameters of each cabinet to the MCU controller through the ZigBee network. The cloud platform obtains the box parameters of each box sent by the MCU controller through the NB-IoT network.

S302: Send the display screen parameters to the client, and obtain corresponding user instructions.

The cloud platform sends multiple cabinet parameters obtained in real time and the corresponding cabinet identifiers as display parameters to the relevant applet in the social application X. The user sends user instructions according to the display parameters displayed in the applet. The user command can be a connection screen command used to control the connection of the LED display, a brightness adjustment command to adjust the brightness of the LED display, a test command to test the display parameters of the LED display, and a correction command to calibrate the display parameters of the LED display. , Upgrade instructions for upgrading the display parameters of the LED display, query instructions for querying the display parameters of the LED display, etc.

S303: Send the user instruction to the display device, so that the display device performs parameter management on the display screen according to the user instruction.

The cloud platform sends user instructions to the controller in the display device through the NB-IoT network, so that the controller parses the user instructions to obtain the box identification corresponding to the box that needs parameter management, and the adjustment corresponding to the regulator used for parameter management For example, the user instruction is to start the No. 1 fan until the cabinet parameter corresponding to the cabinet with the cabinet identifier (1, 1) drops to 30 degrees.

The controller turns on the fan with the regulator ID of No. 1 according to the user's instruction, and cools and dissipates the inside of the box with the box ID of (1, 1), so that the temperature parameter of the box is reduced to 30 degrees.

Through the above display control method, the display parameters of the display device are obtained, the display parameters are sent to the client, the corresponding user instructions are obtained, and the user instructions are sent to the display device, so that the display device performs parameter management on the display according to the user instructions . The NB-IoT network is used to realize the ultra-long-distance wireless communication between the client and the display device, which can remotely manage each cabinet in the display screen. The use of small programs further facilitates the monitoring of display parameters and the transmission of instructions. The two-way communication between the display screen and the client is realized, and the management efficiency of the running state and environmental conditions of the display screen is improved.

Please refer to FIG. 4, which is a flowchart of another method for controlling a display screen according to an embodiment of the application. The display screen control method can be implemented interactively between the client 101, the server 102, and the display device 103 shown in FIG. 1; as shown in FIG. 4, the display screen control method includes but is not limited to the following steps 401 to 403:

S401: Determine the parameter range where the display screen parameter is located.

In one embodiment, the parameter range of the display screen parameter can be determined according to a rounding method or a decimal point accuracy to a certain digit. For example, when the method of determining the parameter range where the display screen parameter is located is rounding, the parameter range where the temperature parameter is determined to be 36.4 degrees is (35 degrees, 40 degrees).

In one embodiment, the server presets multiple parameter ranges for the display screen parameters, and different parameter ranges correspond to different adjustment instructions. For example, the preset parameter ranges of the temperature parameters in the cabinet parameters are (-10 degrees, 10 degrees), (10 degrees, 30 degrees), (30 degrees, 50 degrees), and the three parameter ranges respectively represent the environment of the display device The temperature is low, the ambient temperature is normal, and the ambient temperature is relatively high. The adjustment commands corresponding to the three parameter ranges are: start the power switch of the cabinet and run for 8 hours, without adjustment, start the fan's first-level wind.

In one embodiment, the server obtains the user's adjustment instruction, stores the user's adjustment instruction, and continuously adjusts the corresponding parameter range according to the user's adjustment instruction, so as to realize self-learning of the user's adjustment instruction and automatically adjust the parameter range. For example, when the cabinet parameter is (40 degrees, 50 degrees), the user thinks that (30 degrees, 50 degrees) the corresponding adjustment command (first-level wind power to start the fan) is slower for the cabinet to cool down, and the user sends to the display device The adjustment command of the secondary wind power to start the fan is provided. Then the server modifies the parameter range corresponding to the first-level wind adjustment command for starting the fan from (30 degrees, 50 degrees) to (30 degrees, 40 degrees) according to the user's adjustment instruction, and adjusts the start-up fan's second-level wind power adjustment The parameter range corresponding to the command is adjusted to (40 degrees, 50 degrees).

S402: Determine whether the parameter range is within the historical display screen parameter range corresponding to the display device.

In one embodiment, the historical display screen parameter range is a display screen parameter range pre-stored in the server, including a preset parameter range of the display screen and a parameter range of the display screen adjusted according to a user's adjustment instruction. The server will sequentially match the parameter range of the acquired cabinet parameters with the historical display parameter range. When the parameter range falls within a certain historical display parameter range, the parameter range is within the historical display parameter corresponding to the display device. Scope.

For example, the historical display parameter ranges are (-10 degrees, 10 degrees), (10 degrees, 30 degrees), (30 degrees, 40 degrees), (40 degrees, 50 degrees), and the box identification is (1, 1 ) The temperature parameter of the cabinet corresponding to the cabinet is 36.4 degrees. When the parameter range is (35 degrees, 40 degrees), the parameter range of the temperature parameters (35 degrees, 40 degrees) is in the historical display parameter range (30 degrees) ,40 degree).

S403. If yes, obtain the historical adjustment instruction corresponding to the historical parameter range, and determine the historical adjustment instruction as an adjustment instruction for adjusting the parameters of the display screen.

The parameter range of the temperature parameter (35 degrees, 40 degrees) is in the historical display parameter range (30 degrees, 40 degrees), and the adjustment command corresponding to the historical display parameter range (30 degrees, 40 degrees) (starting the second level of the fan) Wind) is determined as an adjustment instruction for adjusting the temperature parameter 36.4, and the server sends the adjustment instruction to the controller to enable the controller to turn on the fan and use the secondary wind to cool the box identified as (1, 1).

In the above embodiment, the parameter range of the display screen parameter is determined; it is judged whether the parameter range is in the historical display screen parameter range corresponding to the display device; if so, the historical adjustment instruction corresponding to the historical parameter range is obtained, and the historical adjustment instruction is determined to be used Adjustment instructions for adjusting display parameters. Through self-learning user instructions, continuously adjust the historical display parameter range that meets user needs, match the parameter range corresponding to the acquired display parameter with the historical display parameter range, and adjust according to the matched historical display parameter range The instruction to adjust the display screen parameters further improves the intelligence of automatically adjusting the display screen parameters, and improves the management efficiency of the operating state and environmental conditions of the display screen.

In one embodiment, when the parameter range of the display device is not within the parameter range of the historical display screen of the display device, the target historical display screen parameter range corresponding to other target display devices is obtained through the server. The device model and configuration are the same, and the display device connected to the same server. The target historical display screen parameter range corresponding to the target display device includes: a preset parameter range of the target display screen or a parameter range of the target display screen adjusted according to a user's adjustment instruction.

For example, display device A and display device B are display devices of the same model and configuration, and connected to the same server. When the temperature parameters of the box with the box identification (1, 1) in the display device A are in the parameter range (50 degrees, 55 degrees), the historical display parameter range corresponding to the display device A is (-10 degrees) , 10 degrees), (10 degrees, 30 degrees), (30 degrees, 40 degrees), (40 degrees, 50 degrees). The parameter range of the temperature parameter (35 degrees, 40 degrees) is not in the historical display parameter range of the display device A.

The server obtains the target historical display screen parameter ranges of the display device B as (30 degrees, 40 degrees), (40 degrees, 50 degrees), (50 degrees, 60 degrees), respectively. Therefore, the judgment result is that the parameter range (50 degrees, 55 degrees) in which the temperature parameter is located is within the target historical display screen parameter range (50 degrees, 60 degrees) corresponding to the display device B.

S502: If the parameter range is within the target historical display screen parameter range, obtain the target historical adjustment instruction corresponding to the target historical display parameter range, and determine the target historical adjustment instruction as an adjustment instruction for adjusting the display screen parameter.

Obtaining the target historical adjustment instruction corresponding to the target historical display screen parameter range (50 degrees, 60 degrees) corresponding to the display device B is: start the three-level wind of the fan and turn off the cabinet power for 2 hours. Determine the target historical adjustment instruction as an adjustment instruction for adjusting the display screen parameters of display device A, and send it to the controller of display device A for the controller to turn on the fan and use the three-level wind to mark the box as (1, 1 ) To cool down the box, turn off the power supply of the box at the same time, suspend the use of the display function for 2 hours, reduce the operating time, and reduce the temperature parameters of the box.

It can be seen that through the embodiments of this application, it is determined whether the parameter range is within the target historical display screen parameter range corresponding to the target display device. The target display device is a display device of the same model of the display device; if the parameter range is within the target historical display parameter range, then Obtain the target historical adjustment instruction corresponding to the target historical display screen parameter range, and determine the target historical adjustment instruction as an adjustment instruction for adjusting the display screen parameters. Obtain the adjustment instructions corresponding to the display device connected to the same server with the same model and configuration as the display device to adjust the display device, which further improves the intelligence of automatically adjusting the display parameters, and improves the operating status and environment of the display. The management efficiency of the situation.
