[0017] The embodiments of the present application provide an energy-saving control method of a laser page turning pen, as shown in Figure 1 The method comprises the following steps:

[0018] Step S100, determine the laser power regulation space of the laser display of the target laser flip pen and the signal transmission power regulation space of the wireless control module. Specifically, for determining the laser power regulation space of the laser display of the target laser flip pen and the signal transmission power regulation space of the wireless control module, first, for the laser display, the hardware specification and technical document need to be collected to understand the laser diode model, rated power and other information, prepare high-precision laser power meter and optical coupling device, measure multiple times to determine the minimum power value in standby or low brightness state, and measure the maximum power value in the highest brightness stable working state, so as to determine the regulation space. For the wireless control module, the hardware is analyzed and the technical document is consulted to understand the wireless communication technology standard, etc., a test environment containing signal generator, spectrum analyzer, etc. is built, the transmission power is set to the lowest level, the minimum transmission power is measured after excluding interference at a certain distance, and the maximum transmission power is measured in the same way, so as to determine the regulation space, provide a basis for subsequent energy-saving control strategy, and realize energy consumption reduction and energy utilization efficiency improvement.

[0019] Step S200, based on the laser power regulation space, analyze the relationship between laser display brightness and ambient light, and establish a laser display energy-saving control module. Specifically, using professional optical power measurement equipment and brightness detection instruments, gradually change the laser output power within the laser power regulation space of the laser flip pen, measure and record the display brightness at different power, and determine the brightness-power relationship. Then, select multiple samples in the display brightness range, place the flip pen in a test environment where the ambient light brightness can be accurately controlled, simulate various ambient light conditions, invite test personnel to subjectively evaluate the display clarity and eye comfort of each sample in different light, and record the data. Then, calculate the contrast ratio according to the ambient light brightness and display brightness sample, draw the first response curve of contrast ratio and ambient light brightness, and draw the second response curve of visual fatigue score and ambient light brightness. Then, comprehensively analyze the two curves to determine the ambient light brightness range that meets the preset contrast ratio and visual fatigue score threshold, and establish the ambient light-display brightness mapping relationship with the corresponding display brightness sample. Finally, construct the energy-saving control module based on the mapping relationship and the brightness-power relationship, detect the light brightness in real time through the embedded ambient light sensor, determine the appropriate display brightness and laser power, accurately control the laser display drive circuit, realize energy saving, visual effect balance, reduce energy consumption, prolong battery life, improve user experience, and meet the energy-saving and environmental protection concept.

[0020] In a possible implementation, the relationship between the laser display brightness and the ambient light is analyzed based on the laser power regulation space, and a laser display energy-saving control module is established. Step S200 further includes step S210 of performing laser display brightness conversion analysis on the laser display based on the laser power regulation space, generating a display brightness space, and a brightness-power control relationship. Specifically, a high-precision optical power meter and a calibrated brightness measuring instrument are prepared, the target laser flip pen is fixed on a stable test platform, and is placed in a dark room environment to exclude external stray light interference. Then, according to the laser power regulation space, the power is gradually increased in fixed increments from the minimum regulation power, for example, in the range of 1 mW-10 mW, with a step of 0.5 mW, and the power values are set respectively. Each time the power is set, the actual output power is measured by the power meter, and the corresponding display brightness is measured by the brightness measuring instrument, and a plurality of power and brightness data pairs such as (1 mW, brightness value 1) are recorded. Then, all the measured display brightness values are summarized and repeated data is removed to generate the display brightness space of the laser display, which shows the brightness adjustment range. Finally, data fitting or regression analysis methods are used to process the collected large amount of data pairs. If the relationship is linear, a linear regression model is used to fit to obtain an expression in the form of “display brightness=a*laser power+b”, and if it is nonlinear, a suitable model is selected according to the data characteristics to establish the brightness-power control relationship, which provides key support for subsequent energy-saving control and realizes energy-saving and display effect optimization.

[0021] Step S220, randomly generating any display brightness in the display brightness space. Specifically, the minimum value and the maximum value of the generated display brightness space are determined, which are the range boundary values obtained through comprehensive test and analysis of the display brightness of the laser flip pen under different laser power. Then, according to the used programming environment or calculation tool, a function such as the random module in Python that can generate uniformly distributed random numbers in a specified range is selected to generate a random decimal number between 0 and 1. Finally, the random decimal number is mapped to a specific brightness value in the display brightness space by using the formula , for example, a random display brightness value such as 37 nits is calculated under a specific value. Subsequent test and analysis of the ambient light and display effect will be carried out for this value to provide key basic data and operation steps for optimizing the energy-saving control strategy of the laser display, balancing energy saving and display quality, and ensuring the smooth implementation of the technical scheme and the achievement of the target.

[0022] Step S230, the display clarity and human eye comfort of any display brightness under different ambient light are analyzed, the mapping relationship with the display brightness is established, and the ambient light-display brightness mapping relationship is generated. Specifically, a test environment capable of precisely controlling ambient light brightness is built, various ambient lights from 10 lux to 1000 lux are simulated by using a light intensity adjusting device, and the light intensity value is accurately measured and recorded by using a light intensity meter. Then, for a specific display brightness, an image analysis technique and a visual evaluation device are used to capture images of the display displaying test patterns under different ambient lights, parameters such as contrast and edge sharpness are calculated to quantify the display clarity, and the average value is obtained by multiple measurements. At the same time, 20-30 people in the test group are invited to score the visual comfort under different ambient light conditions according to the comfort score scale, and the human eye comfort comprehensive evaluation index value is obtained by statistical analysis. Then, the display clarity threshold and the human eye comfort threshold are determined according to the actual visual quality requirement and the user experience standard, the ambient light brightness values meeting the threshold are screened out, these values are associated and mapped with the display brightness, a data pair is formed, and the ambient light-display brightness mapping relationship is perfected through repeated operations on multiple random display brightnesses, and is presented in the form of a table or a function, thereby providing a decision basis for laser display energy-saving control, enabling the laser flip pen to automatically adjust the brightness according to the ambient light, balancing energy saving and visual effect, and improving energy utilization efficiency and user experience.

[0023] Step S240, the laser display energy-saving control module is established based on the ambient light-display brightness mapping relationship and the brightness-power control relationship. Specifically, the ambient light-display brightness mapping relationship data and the brightness-power control relationship data are integrated, the energy-saving control module architecture is designed, the input, processing logic and output interface are determined. Then, an ambient light sensor is integrated on the laser flip pen, the light signal sensed by the sensor is converted into an electrical signal, after amplification, filtering and analog-digital conversion preprocessing, the digitized ambient light brightness value is transmitted to the energy-saving control module at a certain time interval. Then, the module receives the value, finds the match in the ambient light-display brightness mapping relationship table, and determines the target display brightness value by using a suitable algorithm. Then, the target power parameter is calculated according to the brightness-power control relationship, and the corresponding power control signal is generated for the laser display driving circuit. Finally, the energy-saving control module is integrated into the laser flip pen control system, and its performance is tested and evaluated, including light change response speed, brightness switching smoothness and power control accuracy, etc., and then the algorithm parameters, lookup table data and hardware interface are optimized to improve the module performance, and energy saving and good user experience are realized.

[0024] In a possible implementation, the display clarity and the human eye comfort of different ambient light for the any display brightness are analyzed, a mapping relationship with the any display brightness is established, and an ambient light-display brightness mapping relationship is generated. Step S230 further includes step S231. Based on the any display brightness, a plurality of groups of display brightness samples are collected by testing, wherein each group of display brightness samples includes an ambient light brightness and a visual fatigue score. Specifically, a test space with a closed and accurately controllable ambient light is built, a smart dimming system and other illumination adjusting devices are provided, a laser flipping pen fixing device and a comfortable observation area are installed, and the distance between the test personnel and the laser flipping pen screen is set to be about 0.5-1 m. Then, 20-30 test personnel with different ages, genders, and vision conditions are recruited and trained to make them familiar with the visual fatigue score scale. Then, the display brightness of the laser flipping pen is set to a specific value and remains unchanged, the illumination adjusting device is used to change the ambient light brightness in steps of 50 lux, and the ambient light brightness is set from 50 lux to 1000 lux in sequence. Each brightness value is stable for 5 minutes, during which the ambient light brightness value is measured and recorded by using an illuminance meter. Then, the test personnel score according to the visual feeling, and the comprehensive visual fatigue scores are statistically obtained to form a data pair including the ambient light brightness value and the comprehensive visual fatigue score. A plurality of groups of display brightness samples are obtained for different ambient light brightness by repeating the process, and a plurality of random display brightnesses are repeatedly tested to expand the sample library, provide a data basis for subsequent research and energy-saving control, improve the performance and user experience of the laser flipping pen, and meet the energy-saving and environmental protection requirements.

[0025] Step S232, based on the any display brightness and the ambient light brightness, the contrast ratio is calculated, and a first response curve of the contrast ratio with respect to the ambient light brightness is generated. Specifically, a plurality of groups of ambient light brightness data under a specific display brightness are obtained, and high-precision illuminance meters are used for accurate measurement, so that the error is not more than ±5 lux, and accurate parameters are provided for subsequent calculation. Then, according to the formula (wherein is a fixed display brightness value, is an ambient light brightness value), the corresponding contrast value is calculated for each group of ambient light brightness data , and a series of data pairs is obtained. Then, professional data analysis software or tools, such as Excel, Python data analysis library, and the like, are used, a suitable fitting function type is selected according to the data distribution characteristics, and if the approximation is linear, a linear regression fitting is performed to obtain Formal expression and draw straight line, if nonlinear, try quadratic function, exponential function, etc., to measure the goodness of fit with least squares method, select the best function form to draw the curve, generate the first response curve of contrast to ambient light brightness, intuitively show the change law of contrast with ambient light brightness, provide key reference basis for laser display performance analysis and energy saving control strategy making, help to improve display quality and energy utilization efficiency, meet the actual application requirements.

[0026] Step S233, based on the ambient light brightness and the visual fatigue score, generate the second response curve of visual fatigue score to ambient light brightness. Specifically, collect different ambient light brightness and its corresponding visual fatigue score data under a certain display brightness, and accurately group them according to the ambient light brightness value. Then, calculate the average value of the score data of each ambient light brightness group as the comprehensive score value to reduce the influence of individual differences, and also calculate the standard deviation to understand the dispersion degree. Then, use data analysis software or tools to perform curve fitting with ambient light brightness as the independent variable and the comprehensive score value as the dependent variable, try linear, quadratic, logarithmic, exponential and other function models according to data distribution, select the best model through the goodness of fit index, and draw the second response curve of visual fatigue score to ambient light brightness accordingly. Finally, verify and optimize the curve, substitute the reserved data into the fitting function to calculate the predicted score and compare it with the actual value, if the error is large, re-examine the data, function selection and other factors, adjust and optimize the fitting process to improve the accuracy of the curve, provide favorable basis for laser display energy saving control strategy making, realize energy saving and performance improvement under the premise of ensuring visual comfort, and improve user satisfaction.

[0027] In step S234, the first response curve and the second response curve are combined to identify the coincident ambient light brightness that satisfies the preset contrast threshold and the visual fatigue score. Specifically, the appropriate preset contrast threshold and the preset visual fatigue score threshold are determined by comprehensively analyzing the laser display quality requirements, human eye visual characteristics, industry standards, and user experience research. Then, the data points are extracted from the generated first response curve of ambient light brightness and contrast, and the second response curve of ambient light brightness and visual fatigue score, and the two are plotted in the same coordinate system using professional tools to clearly show their trends. Then, along the ambient light brightness axis, the contrast values of the first response curve and the preset contrast threshold, and the visual fatigue scores of the second response curve and the preset visual fatigue score threshold are compared in sequence to find the ambient light brightness values that satisfy both the contrast reaching or exceeding the preset value and the visual fatigue score being within the preset range. The region of these values is the coincident region, and the corresponding ambient light brightness is the solution. Finally, if necessary, set light conditions similar to the coincident ambient light brightness in the actual laser flip pen test environment, invite test personnel to subjectively evaluate the display clarity and visual fatigue, compare the actual test results with the previous data and theoretical analysis results, if there is a large difference, re-examine the preset threshold, curve fitting and other influencing factors, adjust and optimize the analysis process to improve the accuracy of the coincident ambient light brightness identification, provide accurate and reliable basis for subsequent laser display energy-saving control strategy, enhance the comprehensive performance and practicality of the laser flip pen, achieve better energy-saving effect and user experience.

[0028] Step S235, the any display brightness is associated with the ambient light brightness mapping, generating the ambient light-display brightness mapping relationship. Specifically, the test data for a specific display brightness under different ambient light brightness is collected, covering the ambient light brightness value measured by high-precision illuminometer, the visual fatigue score given by the test personnel and statistically processed, and the contrast value calculated, while ensuring the data is accurate and complete and classified and arranged well. Then, based on the display effect and user experience requirements, the key indicator thresholds such as the minimum contrast threshold and the upper threshold of the visual fatigue score are determined as the screening basis. Then, for each specific display brightness value, the corresponding ambient light brightness data is traversed, and the ambient light brightness value that meets the threshold condition is selected to form the light condition range that can guarantee the visual effect and comfort at this display brightness. Then, the selected ambient light brightness value and the specific display brightness value are paired one by one to construct the ambient light-display brightness mapping relationship, and the relationship is enriched by repeating the operation for multiple different display brightnesses. Finally, the mapping relationship is mathematically modeled and actually scene-sampled tested to optimize and verify, the best mathematical expression is found by function fitting for easy calculation, the deviation is adjusted according to the test results, the relationship model is improved, accurate guidance is provided for laser display energy-saving control, energy saving and display effect are balanced, and user experience and energy utilization efficiency are improved.

[0029] Step S300, based on the signal transmission power control space, the relationship between signal stability and communication distance is analyzed, and a wireless control module energy-saving control module is established. Specifically, a test site with no obstacles is built, multiple uniformly distributed signal receiving points are set, a high-precision signal strength measuring instrument and a communication quality analyzer are prepared. Then, according to the signal transmission power control space of the wireless control module, the transmission power is increased by a reasonable step from the minimum transmission power, and test signals are sent to the receiving points at each power level, and the signal strength values and signal stability index values such as error rate and packet loss rate of each receiving point are recorded simultaneously. Then, a large amount of collected data is analyzed, and a signal strength curve with communication distance is drawn, and a quantitative relationship model between signal stability and communication distance is established by statistical analysis and curve fitting method, such as the function expression "error rate=f(communication distance)". Finally, according to the relationship analysis results, the energy-saving control module is designed combined with application requirements and energy-saving goals, the signal stability threshold range is set, the real-time signal stability index is monitored when the communication distance changes and compared with the threshold, and the required transmission power is calculated according to the relationship model when the threshold is exceeded, and the power is adjusted appropriately after a delay and a step, avoiding frequent adjustment, ensuring communication stability and reliability and high energy efficiency, improving the performance, energy utilization efficiency and practicality of the wireless control module, and meeting market demand.

[0030] In one possible implementation, based on the signal transmission power adjustment space, the relationship between signal stability and communication distance is analyzed, and an energy-saving control module for the wireless control module is established. Step S300 further includes step S310, where any signal transmission power is randomly generated within the signal transmission power adjustment space. Specifically, the technical specifications and hardware parameters of the wireless control module are analyzed to determine the minimum value of its signal transmission power adjustment space. and maximum value These two boundary values ​​limit the range of subsequent random values, ensuring that the generated power value is safe and effective for the equipment. Next, depending on the programming environment or computing tool used, a method such as the `random` module in Python, which can generate uniformly distributed random numbers within a specified range, is selected to first generate a random decimal `r` between 0 and 1. Finally, the formula is used... Map random decimals to specific signal transmission power values ​​within the control space. For example, a random power value such as 9.5mW can be calculated under specific conditions. Based on this, subsequent tests and analyses of signal stability and communication distance will be conducted to provide key data and operational guidance for optimizing the energy-saving control strategy of the wireless control module, balancing energy saving and communication quality, and ensuring the effective implementation of the technical solution and the achievement of the goals.

[0031] Step S320: Perform signal stability analysis on the transmission power of any signal at different distances to generate a communication distance-transmission power mapping relationship. Specifically, construct an open test site with no obvious obstacles and minimal electromagnetic interference. Use high-precision measuring instruments to mark distance points that increase at certain intervals (e.g., 5 meters), starting from 1 meter up to the expected maximum test distance. Set up receiving devices with high-precision signal detection and quality analysis functions at each distance point and connect them to the data acquisition center. Then, set the wireless control module signal transmission power to a randomly generated specific value and keep it constant. Start transmitting the signal from the nearest distance point, and collect stability index data such as received signal strength, bit error rate, and packet loss rate multiple times (e.g., 10-20 times) at each distance point, and record the average value. Then, analyze the data in depth, plot the signal strength variation curve with communication distance, analyze the relationship between bit error rate, packet loss rate, and communication distance, and use statistical analysis and curve fitting methods to establish corresponding functional expressions to describe their quantitative relationship. Finally, the above operation is repeated for multiple different random transmission powers. The relationship models are integrated to generate a communication distance-transmission power mapping relationship, which is presented in tabular or functional form. This provides a decision-making basis for the wireless control module to dynamically adjust the power according to the communication distance, achieve energy-saving optimization and improve performance, and meet the needs of actual application scenarios.

[0032] Step S330: Construct the energy-saving control module for the wireless control module based on the communication distance-transmission power mapping relationship. Specifically, the previously obtained communication distance-transmission power mapping relationship data is compiled and summarized. Based on this, the framework of the energy-saving control module for the wireless control module is designed, clarifying the input (receiving real-time communication distance information), processing logic (calculating the appropriate transmission power according to the mapping relationship), and output interface (sending power adjustment commands). Next, in the actual operating environment, distance measurement sensors or wireless communication system ranging technology are used to monitor the communication distance in real time and transmit it to the energy-saving control module as a digital signal. Then, after receiving the signal, the module searches for or calculates the optimal transmission power value in the mapping relationship and makes fine adjustments based on real-time signal quality indicators. Afterward, a command is generated and sent to the power adjustment unit, which responds quickly and accurately to adjust the transmission power to the target value. Finally, the module performance is continuously monitored, including energy consumption, communication quality stability, and response speed, and optimizations are made accordingly, such as optimizing the mapping relationship, algorithm, or adjusting the transmission power strategy, to balance energy saving and communication, improve overall performance and user experience, and meet market demands.

[0033] In one possible implementation, signal stability analysis is performed on the transmission power of any given signal at different distances to generate a communication distance-transmission power mapping relationship. Step S320 further includes step S321, which involves conducting signal stability tests on the transmission power of any given signal at different distances. Based on the test results, a signal stability curve is established with the signal stability index as the dependent variable and the communication distance as the independent variable. Specifically, an open, flat site free from electromagnetic interference is selected as the test area. Using a high-precision rangefinder or measuring tape, distance points are marked from 1 meter away from the signal source in 5-meter increments to the expected maximum distance (e.g., 50 meters). Each point is equipped with a device that has high-sensitivity reception and accurate analysis capabilities, and the power of the signal transmitting device is set to a specific value. And keep it constant. Next, start the transmitting device, and starting from the nearest test point, the receiving devices at each point synchronously collect data, continuously receiving the signal for 1 minute at each point, and measuring and recording the signal strength every 10 seconds. Bit error rate Packet loss rate For indicators such as signal strength, bit error rate, and packet loss rate, multiple measurements are taken, and the average value is used as the final data for that point. Then, based on actual needs, one or more of these parameters, such as signal strength, bit error rate, and packet loss rate, are selected as dependent variables, and the data is organized to form (…). , Finally, using specialized software or tools, with communication distance as the independent variable, the data pairs are analyzed. Curve fitting is performed on the dependent variable. Based on the data trend, an appropriate function type (such as linear, quadratic, exponential, etc.) is selected to determine the best fitting parameters. The signal stability curve is then plotted to visually demonstrate the change of signal stability index with communication distance, providing a basis for optimizing the performance of wireless communication systems.

[0034] Step S322, based on the signal stability curve, the communication distance satisfying the preset signal stability threshold is generated, and the communication distance is associated with the signal transmission power to generate the communication distance-transmission power mapping relationship. Specifically, the preset signal stability threshold is determined in combination with the application requirements and performance standards of the wireless communication system, such as setting a low bit error rate threshold in a high-precision data transmission scene, focusing on setting a low packet loss rate threshold in signal continuity, and setting a suitable signal strength threshold in ordinary transmission as a basis for judging whether the communication distance meets the standard. Then, a large number of data points are extracted from the existing signal stability curve to lay the foundation for subsequent analysis. Then, along the communication distance dimension, the signal stability index data is compared with the preset threshold one by one, the communication distance meeting the condition is recorded, and the effective communication distance range under a specific transmission power is determined. Finally, the communication distance meeting the threshold is associated with the corresponding transmission power, and the data is recorded in a table, and the complete mapping relationship is generated by repeating the operation for multiple transmission powers, which provides accurate guidance for the wireless control module to adjust the power according to the communication distance, balances energy saving and communication quality, improves system performance and reliability, meets the needs of various application scenarios, and promotes the development of wireless communication technology.

[0035] In a possible implementation, the signal stability of the any signal transmission power under different distances is tested, and a signal stability curve is established according to the test results, with the signal stability index as the dependent variable and the communication distance as the independent variable. Step S321 further includes step S3211, communication testing of the wireless control module under multiple distances is performed, the proportion of error data in the received data packet, the proportion of unsuccessfully received data packets at the receiving end, and the time delay of signal propagation are received and subjected to data standardization processing, and then weighted fusion is performed to generate multiple signal stability indexes corresponding to the multiple distances. Specifically, an open electromagnetic interference-free site is selected, high-precision instruments are used to mark test distance points from near to far (such as 1 meter to 50 meters), and two identical and well-configured wireless control modules are prepared as the transmitting and receiving ends and data acquisition equipment and analysis software. Then, at each distance point, the transmitting end transmits data packets, and the receiving end continuously receives and records data packet information and time delay. After multiple tests, the error data proportion and the proportion of unsuccessfully received data packets at each distance point are calculated, and the average value is taken as the final value. At the same time, the time delay data is processed to remove outliers, and the average time delay and standard deviation are calculated. Then, the Min-Max standardization method is used to process the original data of the three indexes to unify the numerical range. Finally, the three indexes are weighted according to the application requirements and performance standards of the communication system, and the sum is 1. The signal stability index is calculated according to the weighted formula for each distance point. These indexes can reflect the signal stability of the module under different distances, provide a basis for communication performance analysis, and promote the development of wireless communication.

[0036] Step S3212, the test results are generated based on the plurality of distances and the plurality of signal stability indicators. Specifically, the plurality of signal stability indicator data obtained by the wireless control module in the communication test at a plurality of distances is systematically organized and summarized to ensure that the distance is accurately associated with the corresponding indicator data, which lays the foundation for generating the test results and is crucial to ensure the accuracy and completeness of the data.

[0037] Step S400, when the target laser flip pen is activated, energy saving control is performed based on the laser display energy saving control module and the wireless control module energy saving control module. Specifically, a ranging module based on wireless communication technology (such as low-power Bluetooth, radio frequency identification, etc.) is deployed on the target laser flip pen and the multimedia display device respectively. After the laser flip pen is started, it continuously sends wireless signals containing identification information. The multimedia display device receives the signals and uses a signal strength indication algorithm and a pre-stored signal strength and distance corresponding model to identify the real-time communication distance through multiple measurements, filtering and other processing, combined with a dynamic calibration mechanism to control the error within a certain range (such as within 1 meter). Secondly, a high-sensitivity, wide-dynamic-range light brightness sensor with a light shield or special light path design is installed on the multimedia display device to collect data at certain time intervals (such as every second) after preprocessing such as denoising and calibration to ensure that the measurement error is within an acceptable range (such as ±10 lux) to obtain real-time light brightness. Finally, the control unit of the multimedia display device receives and verifies the data from the above two modules through the data fusion and processing module, and according to the pre-set logic and functional requirements, adjusts the transmission power, display device parameters or flip pen operation sensitivity according to the communication distance and light brightness, etc. to trigger corresponding operations, realize intelligent interaction, improve user experience, meet different scene requirements, and promote the development of the system towards intelligence and humanization.

[0038] In a possible implementation, when the target laser page turning pen is activated, energy saving control is performed based on the laser display energy saving control module and the wireless control module energy saving control module, and step S400 further includes step S410. When the target laser page turning pen is activated, a real-time communication distance of the target laser page turning pen to the multimedia display device is identified, and a real-time light brightness is identified. Specifically, after the target laser page turning pen is activated, a signal strength and distance mapping table generated based on experimental tests is first recorded by using a high-precision wireless signal transceiver module built-in the target laser page turning pen and the multimedia display device, respectively. The target laser page turning pen sends a signal pulse containing a specific identifier at a fixed frequency, and the multimedia display device records the signal strength and a time stamp after receiving the signal. The signal is optimized using a multi-antenna technology and a diversity algorithm, and then the initial communication distance is calculated by combining the mapping table. The accurate and stable real-time communication distance is obtained by fusing multiple measurement values by using a Kalman filtering method or the like, and is stored. At the same time, a high-sensitivity light brightness sensor with automatic gain control, temperature compensation, and calibration functions is installed on the multimedia display device. The sensor is started synchronously when the target laser page turning pen is activated, and samples at a fixed interval. After the original light signal is preprocessed, the light brightness is corrected by using a calibration coefficient. The light brightness is processed by using a data filtering and outlier detection algorithm, and the average value is taken as the real-time light brightness value and is stored, thereby providing a basis for subsequent system function adjustment, realizing intelligent interaction, meeting different environmental use requirements, and improving user experience and device practicability.

[0039] In step S420, the real-time light brightness is input into the laser display energy saving control module to match a power control parameter of the laser display, and a target power control parameter is generated. The real-time communication distance is input into the wireless control module energy saving control module to match a signal transmission power, and a target communication control parameter is generated. Specifically, sample data of different light brightness values and laser display power control parameters are pre-stored in the laser display energy saving control module. After the initialization module, the real-time light brightness data is preprocessed, noise is removed, the format is converted, and the unit is unified. Then, an intelligent algorithm such as a neural network is used to match the light brightness as input in the sample set, and the target power control parameter is generated by combining the display working state and weighted fine-tuning, and is sent to the power management unit. In this way, the display power is accurately adjusted, and the light brightness is continuously monitored to re-match the parameter adjustment. At the same time, the wireless control module energy saving control module also pre-stores mapping data of communication distances and signal transmission powers. After initialization, the real-time communication distance data is verified and preprocessed. The transmission power value matched with the distance is determined in the database by using a lookup and fitting algorithm. The target communication control parameter is determined by adaptively adjusting the communication quality index considering the dynamic nature of the communication environment, and is sent to the power adjustment unit to accurately adjust the power by using closed-loop feedback control. The module also optimizes the algorithm and strategy according to the feedback information, realizes efficient energy saving and stable communication, and improves user experience and device application range.

[0040] Step S430: Control the laser display using the target power control parameters, and control the wireless control module using the target communication control parameters. Specifically, for the laser display, the target power control parameters are first obtained from the energy-saving control module, transmitted in a specific format, and then parsed into actual control commands by the control unit, such as laser light source brightness and power supply parameters. Next, the control unit interacts with the hardware driver to adjust the laser light source power and power supply, ensuring the display reaches the appropriate state according to ambient light. During operation, the built-in sensors monitor the display effect and power consumption, providing feedback to the control unit. If there is a deviation, the parameters are fine-tuned and the hardware is readjusted to ensure optimal operation. For the wireless control module, the target communication control parameters are received from the energy-saving control module and converted into a form suitable for the hardware and protocol. The RF transmission unit precisely adjusts the transmission power accordingly, such as controlling the power level based on communication distance and environmental factors. During operation, indicators such as signal strength and bit error rate are continuously monitored and compared with expectations. If communication quality problems are encountered, an automatic trigger mechanism is activated to readjust the transmission power, switch channels, or change the modulation and coding scheme, dynamically saving energy and ensuring communication stability, improving equipment performance and adaptability, and providing technical support for the system.
