Description

Technical Field

[0001] The present invention relates to the field of display power consumption management, and particularly to a real-time monitoring and intelligent regulation system for display power consumption. Background Art

[0002] In the current field of display power consumption management, there are already many related technical solutions. For example, the publication number is: CN117133213A, the application date is May 20, 2022, and the application name is: Control Method of Terminal Display Screen, Terminal and Storage Medium, which discloses the content: The display screen of the terminal includes a first screen and a second screen arranged in a stacked manner. The first screen is a low-power screen, and the second screen is a high-resolution screen. The control method of the terminal display screen includes: detecting the current ambient light brightness of the environment where the terminal is located; when the ambient light brightness is greater than or equal to a preset brightness threshold, controlling to use the first screen for terminal data display; when the ambient light brightness is less than the preset brightness threshold, controlling to use the second screen for terminal data display.

[0003] This solution detects the ambient light intensity through a light sensor and switches the display mode of the screen according to the ambient light intensity to achieve a certain degree of energy saving. However, this solution has obvious deficiencies: it only relies on a single factor of ambient light intensity to regulate the screen, and cannot monitor the actual working state and power consumption data of the display screen in real time, making it difficult to perform accurate and intelligent power consumption regulation according to the actual needs of the display screen in different application scenarios. As a result, in complex and changeable usage scenarios, the power consumption optimization effect of the display screen is not good, and it cannot fully meet the energy saving requirements.

[0004] In summary, the technical problem actually solved by the present invention is how to improve the accuracy of monitoring the power consumption data of the display screen. Summary of the Invention

When the power consumption increase value is less than the power consumption increase threshold, the calculation sub-unit generates power consumption stable information, and the intelligent regulation module generates a first regulation instruction or a second regulation instruction or a third regulation instruction according to the magnitude relationship between the real-time power consumption value and the first threshold, the second threshold, and the third threshold.

[0012] Preferably, when there are more than two real-time power consumption values stored in the storage sub-unit, each time a real-time power consumption value is stored in the storage sub-unit, the real-time power consumption value with the earliest storage time is self-deleted.

[0023] In this embodiment, referring to Figure 1 as shown, a real-time monitoring and intelligent regulation system for the power consumption of a display screen will be described in detail as follows.

[0024] A real-time monitoring and intelligent regulation system for the power consumption of a display screen according to the present invention specifically includes the following: a data acquisition module for real-time collecting the working parameter information of the display screen based on multi-sensor fusion technology, where the working parameter information includes screen brightness, screen refresh rate, display content data, working voltage, and working current; a power consumption calculation module connected to the data acquisition module for receiving the working parameter information and calculating the real-time power consumption value of the display screen based on the working parameter information to generate real-time power consumption information. The calculation formula is: P = U × I , where P represents the real-time power consumption value, U represents the working voltage,I It is represented as the working current; the data analysis module, which is connected to the power consumption calculation module, is used to receive real-time power consumption information and working parameter information, and establish a power consumption - working parameter correlation model after analyzing the real-time power consumption information and working parameter information; the intelligent regulation module, which is connected to the data analysis module, is used to generate a regulation instruction according to the power consumption - working parameter correlation model, the preset power consumption threshold and the usage scenario strategy; the instruction execution module, which is connected to the intelligent regulation module, is used to receive and execute the regulation instruction to adjust the working state of the display screen; the abnormal alarm module, which is connected to the data analysis module, is used to receive the real-time power consumption information, and compare the real-time power consumption value with the alarm power consumption threshold. When the real-time power consumption value is greater than the alarm power consumption threshold, the abnormal alarm module generates and executes an alarm signal.

[0025] Data acquisition module: mainly used to acquire various working parameter information of the display screen. The working parameter information includes but is not limited to screen brightness, screen refresh rate, display content data, working voltage, and working current. It should be noted that the data acquisition module includes but is not limited to accurately obtaining working parameter information through multi-sensor fusion technology to ensure the comprehensiveness and real-time nature of the data. The multi-sensor fusion technology includes an ambient light sensor, a refresh rate sensor, a display content data acquisition unit, and a working voltage / current sensor. The ambient light sensor detects the ambient light intensity through a photosensitive diode, converts the optical signal into an electrical signal, and outputs the ambient light value after analog-to-digital conversion to obtain the screen brightness. The refresh rate sensor detects the horizontal synchronization signal (HSYNC) and vertical synchronization signal (VSYNC) in the display drive power, and uses a frequency counter (such as the timer built in the STM32 series microcontroller) to accurately measure the frequencies of the horizontal synchronization signal and vertical synchronization signal to obtain the screen refresh rate. The display content data acquisition unit extracts the display content data on the display screen through an image processing algorithm. By setting a data acquisition interface (such as a MIPI DSI data collector) between the display driver chip and the display screen, the display data frame is captured in real time. An FPGA (such as the Xilinx Spartan-7 series) is used to decode and analyze the data frame to extract information such as the RGB value and brightness value of the pixel points, and then calculate the color distribution of the display screen and the brightness distribution of the pixel points. The voltage sensor in the working voltage / current sensor uses a voltage division circuit (such as a resistor voltage division network) to convert the working voltage of the display screen into a small voltage signal suitable for ADC acquisition. The current sensor in the working voltage / current sensor converts the current signal into a voltage signal through a Hall effect current sensor (such as the ACS712 series) or a shunt resistance method and then acquires it. The acquired signal is converted into a digital signal by an ADC (ADS1115 high-precision ADC) for use by the power consumption calculation module.

[0026] Power consumption calculation module: The power consumption calculation module is mainly used to receive various working parameter information provided by the data acquisition module, and accurately calculate the real-time power consumption value of the display screen through the built-in power consumption calculation formula and generate real-time power consumption information. The built-in power consumption calculation formula in the power consumption calculation module is P = U × I , where P represents the real-time power consumption value, with the unit of watt (W); U represents the working voltage, with the unit of volt (V); I represents the working current, with the unit of ampere (A). The core logic principle of this calculation formula is to obtain the actual working voltage and working current of the display screen during operation, substitute these two key parameters into the formula for multiplication operation, so as to obtain the power consumed by the display screen at the current moment, that is, the real-time power consumption value. For example, in some embodiments, when the working voltage of the display screen collected by the data acquisition module is 15V and the working current is 0.4A, the power consumption calculation module calculates through the power consumption calculation formula , and can determine that the real-time power consumption value of the display screen at this time is 6 watts. It should be noted that in some embodiments, when calculating, the power consumption calculation module will also preprocess the received working parameter information, including but not limited to removing noise interference, such as using algorithms such as median filtering and mean filtering, to ensure the accuracy and reliability of the working parameter information. The preprocessed working parameter information is used to obtain the accurate real-time power consumption value through the power consumption calculation formula.

[0027] Data analysis module: It is mainly used to receive the real-time power consumption information and working parameter information output by the power consumption calculation module, so as to comprehensively analyze the real-time power consumption information and working parameter information, and establish a power consumption - working parameter correlation model. The methods for analyzing the real-time power consumption information and working parameter information include but not limited to regression analysis, time series analysis, etc., to reveal the internal relationship between the real-time power consumption information and the working parameter information. Regression analysis specifically reveals its change trend by fitting the functional relationship between the real-time power consumption information and the working parameter information; time series analysis is based on historical data to predict future power consumption changes, and the two are combined to construct an accurate power consumption - working parameter correlation model.

[0028] Intelligent regulation module: It is mainly used to generate regulation instructions according to the power consumption - working parameter correlation model established by the data analysis module, the preset power consumption threshold and the usage scenario. That is, the intelligent regulation module generates regulation instructions in real time according to the comparison between the real-time power consumption value and the preset threshold, playing a decision-making role.

[0029] Instruction Execution Module: It is mainly used to precisely adjust the working state of the display screen according to the regulation instructions generated by the intelligent regulation module. The adjustment of the working state includes, but is not limited to, adjusting parameters such as the screen brightness, screen refresh rate, and display content data of the display screen. In this embodiment, the instruction execution module plays a specific execution role, and its work is controlled by the regulation instructions generated by the intelligent regulation module.

[0030] Abnormal Alarm Module: It is mainly used to receive real-time power consumption information. There is a real-time power consumption value in the real-time power consumption information. In the abnormal alarm module, there is a preset alarm power consumption threshold. When the abnormal alarm module receives the real-time power consumption information, it compares the real-time power consumption value with the alarm power consumption threshold. When the real-time power consumption value exceeds the alarm power consumption threshold, the abnormal alarm module immediately triggers the alarm mechanism, generates an alarm signal and synchronously executes it. It should be noted that, in this embodiment, the abnormal alarm module is a comprehensive module that independently makes judgments, generates, and executes. Its independence ensures the timeliness and accuracy of the alarm mechanism, effectively prevents equipment damage or safety hazards caused by abnormal power consumption, and ensures the stable operation of the system. In some embodiments, the triggering mechanism of the abnormal alarm module is not limited to the alarm power consumption threshold, and it can also combine factors such as the temperature and running duration of the display screen to comprehensively evaluate the device status and ensure the comprehensiveness and reliability of the alarm signal.

[0031] It should be noted that the preset alarm power consumption threshold in the abnormal alarm module is greater than the preset power consumption threshold in the intelligent regulation module. For example, in some embodiments, the alarm power consumption threshold is set to 1.2 times the power consumption threshold to distinguish the situation where the power consumption cannot be effectively reduced even after passing through the intelligent regulation module, and to ensure timely alarm when the power consumption abnormally increases. For example, in some specific embodiments, the power consumption threshold is set to 100 watts, and the alarm power consumption threshold is 120 watts.

[0032] Furthermore, the display content data includes the color distribution and pixel brightness distribution of the display screen. The data analysis module calculates the comprehensive energy consumption coefficient of the display content data based on the energy consumption coefficient calculation formula and incorporates the comprehensive energy consumption coefficient into the power consumption - working parameter correlation model. The energy consumption coefficient calculation formula is: . Wherein, C represents the comprehensive energy consumption coefficient of the display content data, represents the brightness of the th pixel point, represents the color energy consumption weight corresponding to the th pixel point, n represents the total number of pixel points.

[0033] In this embodiment, the data analysis module will be described in detail again. The display content data includes the color distribution and pixel brightness distribution of the display screen, and the acquisition method is as described in the above embodiment. The data analysis module calculates the comprehensive energy consumption coefficient of the display content data based on the energy consumption coefficient calculation formula, and incorporates the comprehensive energy consumption coefficient into the power consumption - working parameter correlation model established by the data analysis module, so that the power consumption - parameter correlation model can more accurately reflect the impact of the display content data on power consumption. The energy consumption coefficient calculation formula mentioned in this embodiment is: .

[0034] Among them, C represents the comprehensive energy consumption coefficient of the display content data, represents the brightness of the th pixel, represents the color energy consumption weight corresponding to the th pixel, n represents the total number of pixels. In this embodiment, taking the display screen resolution of 1080P as an example, n =1920×1080, that is, 2,073,600 pixels. The brightness of each pixel is converted from the RGB value to the brightness value (the formula is: ). The color energy consumption weight varies significantly in the impact of different colors on power consumption. For example, in the OLED screen, the color energy consumption weight of red pixels is greater than that of green pixels, which is greater than that of blue pixels. For mixed colors, it is obtained by weighted calculation of the color energy consumption weights of the three primary colors. For example, the color energy consumption weight of red pixels is 0.8 (energy-saving), the color energy consumption weight of green pixels is 1 (benchmark), and the color energy consumption weight of blue pixels is 1.5 (high-consumption). Then, for example, the color energy consumption weight of yellow pixels is the average of the color energy consumption weights of red pixels and green pixels, that is, (0.8 + 1) / 2 = 0.9. Through this method, the power consumption - working parameter correlation model can accurately reflect the actual impact of each color on power consumption, Furthermore, the preset power consumption threshold includes a coefficient threshold, and the preset usage scenario strategy includes an office scenario strategy. In the office scenario strategy, when the comprehensive energy consumption coefficient of the display content data is greater than the coefficient threshold, the intelligent regulation module generates a regulation instruction to reduce the screen brightness, and the instruction execution module controls the display screen to reduce the screen brightness according to the regulation instruction to reduce the screen brightness.

[0035] In this embodiment, the intelligent regulation module will be described in detail again. The preset power consumption threshold in the intelligent regulation module includes a coefficient threshold, and the preset usage scenario strategies include but are not limited to the office scenario strategy. In the office scenario strategy, when the comprehensive energy consumption coefficient of the calculated display content data is greater than the coefficient threshold, the intelligent module will generate a regulation instruction to reduce the screen brightness. After the instruction execution module receives this instruction, it reduces the screen brightness of the display screen. In this embodiment, it mainly focuses on the office scenario strategy. In this scenario, since the display effect of the display screen is relatively low when processing documents and the like during daily office work, reducing the screen brightness of the display screen not only ensures visual comfort but also effectively reduces energy consumption, achieving energy-saving optimization in the office scenario.

[0036] Further, the preset power consumption threshold includes a first threshold, a second threshold, and a third threshold, and the first threshold is less than the second threshold, and the second threshold is less than the third threshold; when the real-time power consumption value is greater than or equal to the first threshold and less than the second threshold, the intelligent regulation module generates a first regulation instruction. When the instruction execution module executes the first regulation instruction, it reduces the screen refresh rate; when the real-time power consumption value is greater than or equal to the second threshold and less than the third threshold, the intelligent regulation module generates a second regulation instruction. When the instruction execution module executes the second regulation instruction, it reduces the screen refresh rate and the screen brightness; when the real-time power consumption value is greater than or equal to the third threshold, the intelligent regulation module generates a third regulation instruction. When the instruction execution module executes the third regulation instruction, a prompt message is displayed on the display screen.

[0037] In this embodiment, the intelligent regulation module will be described in detail again. The preset power consumption threshold in the intelligent regulation module also includes a first threshold, a second threshold, and a third threshold, and the relationship between the first threshold, the second threshold, and the third threshold is a progressive relationship, specifically, the first threshold is less than the second threshold, and the second threshold is less than the third threshold. When the real-time power consumption value reaches different thresholds, the intelligent regulation module generates different regulation instructions.

[0038] Specifically, when the real-time power consumption value is greater than or equal to the first threshold and less than the second threshold, the intelligent regulation module generates a first regulation instruction. The regulation operation corresponding to the first regulation instruction only reduces the screen refresh rate of the display screen. Therefore, when the instruction execution module executes the first regulation instruction, it reduces the screen refresh rate of the display screen.

[0039] When the real-time power consumption value is greater than or equal to the second threshold and less than the third threshold, the intelligent regulation module generates a second regulation instruction. Therefore, when the instruction execution module executes the second regulation instruction, it reduces the screen refresh rate and the screen brightness of the display screen.

[0040] When the real-time power consumption value is greater than or equal to the third threshold, the intelligent regulation module generates a third regulation instruction, the instruction execution module executes the instruction, and an energy-saving prompt message is displayed on the display screen to remind the user.

[0041] In this embodiment, a specific scenario will be taken as an example to elaborate on the above first regulation instruction, second regulation instruction, and third regulation instruction in detail. For example, the refresh rate range of the 1080P display screen is 60Hz to 240Hz, the display brightness is 250nit to 350nit, the minimum power consumption of the display screen is 15W, the maximum power consumption of the display screen is 25W, the refresh rate is 150Hz, and the display brightness is 300nit during a certain use. The first threshold is set to 18W, the second threshold is set to 20W, and the third threshold is set to 23W. When the real-time power consumption value calculated by the power consumption calculation module is 19W, since 19W is greater than 18W of the first threshold and less than 20W of the second threshold, the intelligent regulation module generates a first regulation instruction. When the instruction execution module executes the first regulation instruction, the refresh rate of the display screen is reduced from 150Hz to 120Hz to reduce power consumption. When the real-time power consumption value is 21W, since 21W is greater than 20W of the second threshold and less than 23W of the third threshold, the intelligent regulation module generates a second regulation instruction. When the instruction execution module executes the second regulation instruction, the refresh rate of the display screen is reduced from 150Hz to 90Hz, and the display brightness is reduced from 300nit to 250nit. When the real-time power consumption value is 24W, since 24W is greater than 23W of the third threshold, the intelligent regulation module generates a third regulation instruction, the instruction execution module executes the instruction, and a prompt message is displayed on the display screen. The prompt message includes but is not limited to "excessive power consumption", etc. That is, in this embodiment, through the hierarchical setting of the power consumption threshold, the hierarchical control of the power consumption of the display screen is realized.

[0042] Further, when the real-time power consumption value is greater than or equal to the first threshold and less than the second threshold, the intelligent regulation module generates a first regulation instruction infinitely according to the ratio of the real-time power consumption value to the screen refresh rate value. When the instruction execution module executes the first regulation instruction, the screen refresh rate is infinitely reduced; when the real-time power consumption value is greater than or equal to the second threshold and less than the third threshold, the intelligent regulation module generates a second regulation instruction infinitely according to the ratio of the real-time power consumption value to the screen refresh rate value and the screen brightness value. When the instruction execution module executes the second regulation instruction, the screen refresh rate and the screen brightness are infinitely reduced.

[0043] In this embodiment, the intelligent control module will be described in detail again. In this embodiment, the specific values described in the above embodiment will be used for detailed description again. The refresh rate range of the 1080P display screen is 60Hz to 240Hz, the display brightness is 250 nit to 350 nit, the minimum power consumption of the display screen is 15W, and the maximum power consumption of the display screen is 25W. During a certain use, the refresh rate is 150Hz and the display brightness is 300 nit. The first threshold is set to 18W, the second threshold is set to 20W, and the third threshold is set to 23W.

[0044] When the real-time power consumption value is greater than or equal to the first threshold and less than the second threshold, that is, when the real-time power consumption value is 19.5W, the intelligent control module generates a first control instruction according to the ratio of 19.5W to 150Hz. That is, the ratio of 19.5W to 150Hz is 0.13. Since the current refresh rate is 150Hz, the difference between the current refresh rate and the minimum refresh rate is 90Hz. Then 0.13×90 = 11.7Hz. Therefore, when the instruction execution module executes the first control instruction, the refresh rate is reduced from 150Hz to 138.3Hz. For another example, when the real-time power consumption value is 18.5, the ratio of the real-time power consumption value of 18.5W to 150Hz is 0.12, and the difference between the current refresh rate and the minimum value is 90Hz. Then 0.12×90 = 10.8Hz, and the refresh rate is reduced from 150Hz to 139.2Hz. Therefore, when the refresh rate is fixed, when the instruction execution module executes the first control instruction, the higher the real-time power consumption value, the greater the reduction in the refresh rate.

[0045] Similarly, when the real-time power consumption value is greater than or equal to the second threshold and less than the third threshold, such as when the real-time power consumption value is 22W, the intelligent control module generates a second control instruction according to the ratio of 22W to 150Hz and 300 nit. That is, the ratio of 22W to 150Hz is 0.147. Since the current refresh rate is 150Hz, the difference from the minimum value is 90Hz, and 0.147×90 = 13.23Hz, so the refresh rate is reduced to 136.77Hz; the ratio of 22W to 300 nit is 0.073. Since the current display brightness is 300 nit, the difference from the minimum value is 50 nit. Therefore, 0.073×50 = 3.65 nit, and the display brightness is reduced to 296.35 nit. That is, when the instruction execution module executes the second control instruction, the higher the real-time power consumption value, the greater the reduction in the refresh rate and the brightness.

[0046] Furthermore, a statistical unit is provided in the intelligent regulation module. The statistical unit includes a storage subunit and a calculation subunit. Among them, a power consumption increase threshold is provided in the calculation subunit. The storage subunit is used to store the corresponding real-time power consumption values according to a preset interval duration threshold. The calculation subunit is used to compare and calculate the latest stored real-time power consumption value with the previously stored real-time power consumption value in real time to obtain a power consumption increase value, and compare the power consumption increase value with the power consumption increase threshold. When the power consumption increase value is greater than or equal to the power consumption increase threshold, the calculation subunit generates power consumption increase information, and the intelligent regulation module generates a first regulation instruction, a second regulation instruction, or a third regulation instruction according to the power consumption increase information. When the power consumption increase value is less than the power consumption increase threshold, the calculation subunit generates power consumption stability information, and the intelligent regulation module generates a first regulation instruction, a second regulation instruction, or a third regulation instruction according to the magnitude relationship between the real-time power consumption value and the first threshold, the second threshold, and the third threshold.

[0047] In this embodiment, the intelligent regulation module will be described again. A statistical unit is provided in the intelligent regulation module. The statistical unit includes a storage subunit and a calculation subunit, and a power consumption increase threshold is provided in the calculation subunit. The storage subunit stores the real-time power consumption values at preset intervals, that is, the storage subunit will store the real-time power consumption values calculated by the power consumption calculation module once every fixed period of time. The calculation subunit then compares the latest real-time power consumption value with the previous real-time power consumption value in real time to calculate the power consumption increase value, and compares the calculated power consumption increase value with the power consumption increase threshold. If the power consumption increase value is greater than or equal to the preset power consumption increase threshold, the calculation subunit generates power consumption increase information and sends it to the intelligent regulation module, and the intelligent regulation module generates a first regulation instruction, a second regulation instruction, or a third regulation instruction according to the increase information to achieve more refined power consumption management. If the power consumption increase value is less than the preset power consumption increase threshold, the calculation subunit generates power consumption stability information, and the intelligent regulation module generates a first regulation instruction, a second regulation instruction, or a third regulation instruction according to the method of the above embodiment to ensure the stable operation of the device in the low-power state and extend the service life. In this embodiment, real-time regulation is performed according to the power consumption increase of the display screen. For example, if the first stored real-time power consumption value is 15.5W and the second stored value is 16.5W, the calculation subunit compares 16.5W with 15.5W to obtain a power consumption increase value of 1W. If the preset power consumption increase threshold is 0.8W, the calculation subunit generates power consumption increase information, and the intelligent regulation module generates a first regulation instruction, or a second regulation instruction, or a third regulation instruction. If the second stored real-time power consumption value is 15.6W, the calculation subunit compares 15.5W with 15.6W to obtain a power consumption increase value of 0.1W, which is less than the preset threshold of 0.8W, and the calculation subunit generates power consumption stability information.

[0048] Further, when there are more than two real-time power consumption values stored in the storage subunit, each time a real-time power consumption value is stored in the storage subunit, the real-time power consumption value with the earliest storage time is self-deleted.

[0049] In this embodiment, the storage subunit will be described in detail. The storage subunit adopts a first-in, first-out mechanism to ensure efficient utilization of the storage space. The stored real-time power consumption values are more than two, ensuring that the calculation subunit always has sufficient comparison data. For example, in some embodiments, the storage subunit is set to store three real-time power consumption values. When the fourth real-time power consumption value is stored, the earliest one is automatically deleted, so that the storage subunit does not occupy a large amount of storage space, and at the same time ensures that the calculation subunit can accurately analyze the power consumption change trend.

[0050] Further, the storage subunit is also used to store each power consumption increase value; the calculation subunit is also used to calculate the power consumption time period of the display screen according to at least two power consumption increase thresholds, and the intelligent control module generates a first control instruction or a second control instruction or a third control instruction before the minimum value of the power consumption time period.

[0051] In this embodiment, the storage subunit will be described in detail again. The storage subunit will also be used to store each power consumption increase value calculated by each calculation subunit, and the calculation subunit will calculate the power consumption time period of the display screen according to at least two stored power consumption increase values, and then the intelligent control module generates a first control instruction or a second control instruction or a third control instruction based on the minimum value of the power consumption time period. In this embodiment, the power consumption time period of the display screen is calculated through the stored power consumption increase values, and the first control instruction or the second control instruction or the third control instruction is generated predictively. For example, in some specific embodiments, the time period calculated by the calculation subunit according to the stored power consumption increase values is from 16:00 to 18:00 every day, then the intelligent control module generates a first control instruction or a second control instruction or a third control instruction before 16:00 every day. It should be noted that how long before the power consumption time period to generate the first control instruction or the second control instruction or the third control instruction can be set by itself. It should be noted that since the real-time power consumption value is obtained and calculated according to the real-time time, there is still a time tag in the power consumption increase value calculated from the real-time power consumption value. When the calculation subunit calculates the power consumption time period, it calculates according to the time tag corresponding to each power consumption increase value.
