However, in order to better display cultural relics and reduce the impact of light aging, different materials have different requirements for the illumination and color temperature of the light in multimedia display cabinets. For example, paintings, weaving and embroidery cultural relics require low illumination (<50lux) and warm light (color temperature 2700K-3000K) to protect pigments and paper; while pottery and metal cultural relics require higher illumination (150-300lux) and cold light (color temperature 5000K-6500K) to highlight their texture and details. In addition, the idle scenes and exhibition areas of the display cabinets are also different. Different display scenes also require different lighting configurations. In the existing technology, these lighting adjustment processes require frequent manual operations, and the lighting switching is abrupt, which not only increases the workload of librarians, but also easily affects the audience's viewing experience due to sudden lighting effects. Therefore, there is an urgent need for a lighting intelligent control method and system for multimedia display cabinets to achieve real-time early warning of personnel activities, intelligent identification of cultural relics categories, and automatic adjustment of lighting requirements.

[0021] The present invention provides a lighting intelligent control method and system for a multimedia showcase, which has the following beneficial effects: (1) Through real-time early warning of personnel activities, intelligent identification of cultural relics categories, and automatic adjustment of lighting requirements, it is also possible to dynamically generate smooth color temperature and illumination values ​​according to the cultural relics categories and display scene requirements, gradually adjust lighting parameters, avoid abrupt lighting changes, and ensure smooth transition of lighting effects without affecting the audience experience; first, multiple sets of sensors are deployed in the display cabinet, combined with AI target detection algorithms and sensor networks, to analyze in real time whether people are close to the display cabinet, and start the outdoor lighting adjustment process by issuing early warning signals. Subsequently, the cultural relic recognition module uses web crawler technology to dynamically capture professional data related to cultural relic lighting requirements, combined with the current interior lighting information data collected by the light sensor, and accurately identifies the type of cultural relics through RFID technology, generates target lighting data, and calculates several smooth color temperature values ​​Zph and several smooth illumination values ​​Zzh through a linear difference algorithm to ensure that the lighting is smooth. At the same time, the data are sorted, and the color temperature and illumination achieved at the corresponding time point of each adjustment step are gradually executed to achieve a smooth transition of the interior lighting effect, and the lighting adjustment results are verified in real time until the lighting effect of the interior lamps reaches the target color temperature value Sxq and the target illumination value Zxq, which fully meets the special lighting requirements of different cultural relics materials in the background technology, and dynamically adapts to the different lighting requirements of display and idle scenes. Through intelligent lighting adjustment, abrupt changes and frequent operations caused by manual lighting adjustment are avoided, and the audience's visual experience is optimized; at the same time, by dynamically matching the target lighting parameters, the cultural relics are protected from light aging or excessive lighting, and their preservation life is extended. Ultimately, the labor management cost is significantly reduced, and the efficient, intelligent and sustainable display cabinet lighting control is realized.

[0022] (2) The combination of the personnel activity warning module and the cultural relic identification module improves the dynamic response capability to human activities in the environment. Through the collaborative work of high-definition cameras and ultrasonic sensors, it can capture human activities around the display cabinet in real time, and combine AI algorithms and target detection technology to accurately determine whether a person is close to the display cabinet. When approaching behavior is detected, a warning signal is immediately issued, and the type, age, and use of the cultural relic are automatically obtained through radio frequency identification technology. At the same time, the relevant lighting demand parameters are dynamically extracted by combining web crawler technology, and matched with the real-time data collected by the light sensor to provide an accurate basis for subsequent lighting adjustment. This design not only avoids the delay and error caused by manual identification, but also can dynamically adjust the lighting status according to the special needs of different types of cultural relics, ensuring that the display effect and protection needs of each cultural relic are taken into account. Especially in the scene where the display cabinet frequently switches between idle and display states, it also improves the intelligent lighting control effect of multimedia display cabinets in different human activity scenes.

[0023] (3) The combination of the lighting adjustment module and the execution module provides important support for the precise control and smooth transition of the display cabinet lighting. Through the coordinated work of the color temperature adjustment unit and the illumination adjustment unit, the linear difference algorithm is used to gradually adjust the current lighting state to the target state, and a number of smooth color temperature values ​​Zph and smooth illumination values ​​Zzh are generated. The execution module sorts and gradually judges the smooth color temperature values ​​Zph and smooth illumination values ​​Zzh to ensure that there is no sudden change during the lighting adjustment process. When the color temperature and illumination achieved at the time point corresponding to the adjustment step do not reach the target color temperature value Sxq and the target illumination value Zxq, the execution module can automatically trigger the control. The adjustment command is issued to execute the color temperature and illuminance at the time point corresponding to the next adjustment step until the target lighting requirements are met. In addition, the executed smooth color temperature values ​​Zph and smooth illuminance values ​​Zzh will be stored in the database to provide efficient reference for the subsequent lighting management of the same cultural relics category. This dynamic adjustment mechanism not only optimizes the audience's visual experience and avoids abrupt lighting changes, but also effectively reduces the frequent switching of lamps and extends the service life of the equipment. At the same time, it achieves the goal of energy saving and environmental protection. While meeting the display needs, it improves the level of cultural relics protection and provides a sustainable solution for the intelligent control of lighting in multimedia showcases.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1 See also Figure 1 , the present invention provides a lighting intelligent control system for a multimedia showcase, including a field deployment module, a personnel activity warning module, a cultural relic recognition module, a lighting adjustment module and an execution module; The field deployment module is used to deploy a number of sensors on the multimedia display cabinet where cultural relics need to be displayed, and connect them with the data exchange device in the multimedia display cabinet through a wired connection; The personnel activity warning module is used to use a high-definition camera and an ultrasonic sensor, combined with AI recognition technology and a target detection algorithm, to determine whether the current person intends to approach the multimedia display cabinet, and if so, to issue a warning signal; The cultural relic identification module is used to obtain the light target parameter data and the current interior lighting information data by using the web crawler technology and the deployed light sensor after receiving the warning signal, and to determine the type of cultural relic by using the radio frequency identification technology, and match it with the light target parameter data to obtain the cultural relic target lighting data; The light adjustment module is used to analyze the current interior lighting information data and the cultural relic target lighting data, and at the same time combine the linear difference algorithm to obtain a number of smoothed color temperature values ​​Zph and smoothed illumination values ​​Zzh; The execution module is used to determine whether the smoothed color temperature value Zph and the smoothed illuminance value Zzh reached at the time point corresponding to each adjustment step reach the target color temperature value Sxq and the target illuminance value Zxq. If not, the execution instruction is triggered to execute the color temperature and illuminance at the time point corresponding to the next adjustment step until the illumination of the interior lamp reaches the target color temperature value Sxq and the target illuminance value Zxq.

[0027] In this embodiment, by deploying multiple sets of sensors in the display cabinet and combining AI recognition technology with target detection algorithm, it is possible to monitor personnel activities in real time and determine whether personnel have the intention to approach the display cabinet, thereby triggering an early warning signal; using web crawler technology to obtain lighting demand target parameters, combined with real-time data collection of light sensors, using RFID technology to intelligently identify the category of cultural relics and their corresponding lighting requirements, dynamically matching the current lighting state with the target lighting requirements, and the lighting adjustment module calculates several smoothed color temperature values ​​Zph and smoothed illuminance values ​​Zzh based on the linear difference algorithm, and gradually adjusts the lighting through the execution module to ensure that the lighting It smoothly transitions from the initial state to the target state to avoid visual discomfort caused by sudden changes in light. At the same time, the execution module can determine whether the adjustment result meets the needs of cultural relics display. If not, it will automatically trigger new instructions until the interior lighting reaches the target color temperature value Sxq and the target illumination value Zxq. It not only realizes the automatic adjustment of the lighting environment of cultural relics, reduces the burden of manual operation, effectively protects cultural relics from excessive light, and extends the preservation life of cultural relics. In addition, the smooth transition of the lighting adjustment process greatly optimizes the audience's viewing experience and enhances the overall technological sense and intelligence level of lighting control of exhibition multimedia showcases.

[0028] Example 2 Please refer to Figure 1Specifically: the field deployment module is used to deploy a number of sensors on a multimedia showcase where cultural relics need to be displayed, the sensors including ultrasonic sensors, high-definition cameras, light sensors and RFID sensors, and the sensors are connected to a data exchange device in the multimedia showcase through a wired connection. The data exchange device is used to pre-process the data collected by the sensors, and is also used to deploy a variety of lamps with constant current dimming drivers for the exterior and interior scenes of the multimedia showcase, and the types of lamps include downlights, spotlights and LED light strips.

[0029] In this embodiment, ultrasonic sensors, high-definition cameras, light sensors and RFID sensors are deployed on site and connected to data exchange equipment by wire, so as to realize the perception and intelligent management of the light and environment inside and outside the showcase. The real-time data collected by the sensor can be quickly pre-processed to provide an accurate basis for subsequent light adjustment. At the same time, both the exterior and interior scenes are equipped with a variety of constant current dimming driven lamps, including downlights, spotlights and LED light strips, to achieve precise lighting control of different display areas. This design not only ensures the flexibility and accuracy of the cultural relics display lighting, but also reduces the response time of light adjustment through the efficient coordination of sensor fusion and data exchange equipment, and avoids errors and delays in human operation. The constant current dimming driven lamps can dynamically adjust the light intensity and color temperature according to the category of cultural relics and scene requirements, effectively extending the life of the lamps, while protecting the cultural relics from light damage, optimizing the technological level of the cultural relics display environment, and laying the foundation for the intelligent control of light in multimedia showcases.

[0030] Example 3 Please refer to Figure 1 ,Specifically: the personnel activity warning module includes a personnel activity analysis unit and a warning unit; The personnel activity analysis unit is used to use a high-definition camera to take real-time pictures of the images around the multimedia showcase, and combine AI recognition technology and target detection algorithm to identify whether there is a person in the image to obtain the person recognition confidence Pzx, and also measure the distance from the person to the multimedia showcase according to the transceiver signal of the ultrasonic sensor to obtain the person's proximity distance Lkj; It should be noted that the personnel identification confidence Pzx is obtained by continuously capturing real-time images around the multimedia display cabinet through a high-definition camera, and analyzing the targets in the image in combination with AI recognition technology and target detection algorithm. First, the captured image is preprocessed, including resolution adjustment, noise filtering and target area selection. Then, the AI ​​model is used to detect whether there is a person in the image. The model outputs the probability value of the human body existence based on the input features including human body contour, posture, and color distribution, which is the personnel identification confidence Pzx. The personnel identification confidence Pzx value range is usually between 0 and 1, indicating the degree of credibility of the current detection result. For example, a personnel identification confidence Pzx of 0.9 means that there is a 90% certainty in the judgment that it is a human body.

[0031] The person identification confidence Pzx and the person proximity distance Lkj are normalized, and the person proximity value Zkj is obtained after calculation. The person proximity value Zkj is specifically obtained by the following formula:

[0032] In the formula, and They are respectively represented as the weight values ​​of the person identification confidence Pzx and the person proximity distance Lkj.

[0033] Specifically, the warning unit is used to preset a degree threshold P, and compare the person proximity value Zkj with the preset degree threshold P to determine whether the current person has the intention to approach the multimedia showcase. The specific process is as follows; If the person proximity value Zkj ≥ the degree threshold P, it indicates that the current person intends to approach the multimedia showcase, and at this time, a warning signal is sent out, and at the same time, a first exterior lighting instruction is sent to the constant current dimming driver of the exterior lighting fixture, wherein the first exterior lighting instruction is to turn on the exterior lighting fixture and adjust the lighting illumination to 300 lux; If the personnel proximity value Zkj is less than the degree threshold P, it means that the current person has no intention to approach the multimedia showcase. At this time, the multimedia showcase is in an unattended state. At this time, no additional warning signal is issued, and a second exterior lighting instruction is sent to the constant current dimming driver of the exterior lighting fixture. The content of the second exterior lighting instruction is to turn off the exterior lighting fixture.

[0034] In this embodiment, the high-definition camera is combined with AI recognition technology and target detection algorithm to achieve accurate recognition of human activities around the multimedia showcase, and the ultrasonic sensor is used to measure the distance between the person and the multimedia showcase, and the person's proximity value Zkj is calculated. This design can not only accurately judge whether the person has the intention to approach the showcase, but also realize automatic warning and intelligent lighting control by setting the degree threshold P. When a person approaches the multimedia showcase, it can quickly issue a warning signal and adjust the exterior lighting to an appropriate illumination of 300lux to enhance the audience's visual focus and interactive experience; conversely, when no one approaches, the exterior lighting is automatically turned off to save energy. This dynamic adjustment mechanism avoids the waste of resources caused by the long-term opening of traditional lights, significantly improves the intelligent level of multimedia showcase lighting management, and achieves a perfect balance between efficient response and energy saving and environmental protection, while reducing the need for manual intervention, providing an efficient, intelligent and sustainable solution for the operation of multimedia showcases.

[0035] Example 4 Please refer to Figure 1 ,Specifically: the cultural relic identification module includes a light data collection unit and a category identification unit; The light data collection unit is used to access the website page by using the web crawler technology after receiving the early warning signal, automatically grab relevant literature on the light aging of cultural relics and the lighting needs of cultural relics, and screen out the lighting demand target parameters of the corresponding types of cultural relics to construct the light target parameter data, the light target parameter data includes the lighting parameters of paintings and embroidery, the lighting parameters of gemstones and jade, and the lighting parameters of pottery and metal, and also uses the deployed light sensors to collect the lighting environment lighting conditions of the interior lighting fixtures to obtain the current interior lighting information data, the current interior lighting information data includes the current color temperature value Sqs and the current illuminance value Zqs, and the light target parameter data and the current interior lighting information data are sent to the database for storage; It should be noted that the lighting parameters for paintings, weaving and embroidery, gemstones and jade, and pottery and metal in the lighting target parameter data are as follows: paintings, weaving and embroidery cultural relics require low illumination to avoid direct exposure to excessive light on the surface of the works and to protect the pigments and paper of the picture. The standard range of illumination is less than 50 lux, and the recommended chromaticity range is 2700K-3000K; gemstones and jade cultural relics require moderate illumination to highlight their surface texture and texture while avoiding direct exposure to excessive light. The recommended illumination range is 100 lux-150 lux, and the recommended chromaticity range is 2700K-3000K; pottery and metal cultural relics require moderate illumination to highlight their metallic texture and details while protecting their surfaces from the influence of light.

Through feature extraction and matching analysis of cultural relics, the lighting can be dynamically adjusted to an appropriate color temperature and illumination to ensure that the protection needs and display effects of cultural relics are taken into account. Especially for different types of cultural relics, including paintings, embroidery, gemstones, jade, pottery and metal, personalized lighting adjustment can be achieved according to their unique needs, maximizing the life of the cultural relics and improving the display quality, while reducing human intervention, and achieving efficient and intelligent display cabinet management.

After feature extraction and combined with the linear difference algorithm, several transition target color temperature values ​​Zgd are obtained. Take one of the transition target color temperature values ​​Zgd as an example: The transition target color temperature value Zgd of the i-th transition time period i , which is obtained by the following formula:

[0040] Specifically, it is used to select the adjustment frequency Pv according to the duration of the transition period and calculate the total number of adjustment steps , which is specifically expressed by the following formula:

[0041] It should be noted that the number of adjustment steps refers to the specific adjustment stages or times divided in the process of adjusting the color temperature and illumination of the light from the current state to the target state. It is to decompose the overall lighting adjustment process into multiple small changes to achieve a smooth transition and avoid sudden changes that cause discomfort to the audience's vision. Each adjustment step corresponds to a corresponding lighting parameter value. By gradually executing each step of adjustment, it is ensured that the light gradually approaches the target state. The number of adjustment steps usually depends on the total length of the adjustment time and the frequency of adjustment. For example, more adjustment steps means a smaller change each time and a smoother transition, which further enhances the softness and visual effect of the lighting changes, while reducing the negative impact on cultural relics protection and audience experience during the lighting adjustment process.

[0042] The transition target color temperature value Zgd obtained in each transition time period is compared with the total number of adjustment steps Associated, fitting to obtain several smoothed color temperature values ​​Zph, take one of the smoothed color temperature values ​​as an example Zph: the smoothed color temperature value of the jth adjustment step in the i-th transition time period , which is obtained by the following formula:

[0043] In the formula, It is represented as the transition target color temperature value of the i-th transition period, It is represented as the smoothed color temperature value of the j-1th adjustment step in the i-th transition period, It is expressed as the total number of adjustment steps in the i-th transition period, It is expressed as the jth adjustment step number in the i-th transition period, It is represented by the remaining adjustment steps of the i-th transition time period, where i represents the number of the corresponding transition time period, and j represents the number of the adjustment steps in the corresponding transition time period.

[0044] Specifically, the illumination adjustment unit analyzes the current interior lighting information data and the cultural relic target illumination data in the database, and associates them with the middle time point Tzj of each transition time period. After feature extraction and combined with the linear difference algorithm, several transition target illumination values ​​Zzd are obtained. Take one of the transition target illumination values ​​Zzd as an example: the transition target illumination value Zzd of the i-th transition time period i , which is obtained by the following formula:

[0045] Where Zqs represents the current illumination value, Expressed as the target illumination value, Represented as the middle time point of the i-th transition period, Represents the starting time point, It is represented as the target time point, where i represents the number of the corresponding transition time period; The transition target illumination value Zzd obtained in each transition time period is compared with the total number of adjustment steps Associated, fitting to obtain several smoothed illuminance values ​​Zzh, taking one of the smoothed illuminance values ​​as an example Zzh: the smoothed illuminance value of the jth adjustment step in the i-th transition time period , which is obtained by the following formula:

[0046] In the formula, It is expressed as the transition target illumination value of the i-th transition time period, It is expressed as the smoothed illuminance value of the j-1th adjustment step in the i-th transition period, It is expressed as the total number of adjustment steps in the i-th transition period, It is expressed as the jth adjustment step number in the i-th transition period, It is represented by the remaining adjustment steps of the i-th transition time period, where i represents the number of the corresponding transition time period, and j represents the number of the adjustment steps in the corresponding transition time period.

[0047] In this embodiment, the color temperature adjustment unit and the illumination adjustment unit cooperate with each other, and the linear difference algorithm and the step adjustment technology are combined to realize the smooth transition of the lighting parameters, thereby achieving the intelligent effect of dynamic adjustment. The current color temperature value Sqs and the current illumination value Zqs are respectively analyzed with the target value for the lighting adjustment time. First, the total adjustment time TzT is evenly divided into a number of transition time periods Tsd, and then the middle time point Tzj is extracted in each time period to calculate the transition target color temperature value Zgd and the transition target illumination value Zzd of each transition time period. Furthermore, according to the length of each time period and the adjustment frequency Pv, the specific total number of adjustment steps is refined. , generate several smooth color temperature values ​​Zph and smooth illuminance values ​​Zzh. Through this phased and gradual adjustment method, it can effectively avoid the interference of sudden changes in light on the audience experience and ensure the softness and stability of light changes. At the same time, this real-time and dynamic light adjustment mechanism can meet the special needs of different types of cultural relics for color temperature and illumination, which not only protects the material of cultural relics from the influence of light aging, but also shows the best display effect. The intelligent adjustment method reduces the need for manual intervention, optimizes the service life of lamps, and achieves the purpose of energy saving and environmental protection through precise control. On the whole, it fully reflects the advantages of efficient, intelligent and precise adjustment of the intelligent control of light in multimedia showcases.

[0048] Example 6 Please refer to Figure 1 Specifically: the execution module is used to use a sorting algorithm, and according to the color temperature and illumination at the time point corresponding to each adjustment step, respectively arrange the obtained several smooth color temperature values ​​Zph and several smooth illumination values ​​Zzh in ascending order to obtain a data column, wherein the several smooth color temperature values ​​Zph and several smooth illumination values ​​Zzh in the data column respectively represent the color temperature and illumination reached at the time point corresponding to each adjustment step, and by judging whether the color temperature and illumination reached at the time point corresponding to each adjustment step reach the target color temperature value Sxq and the target illumination value Zxq, if not, trigger an execution instruction, and send the execution instruction to the next adjustment step to execute the color temperature and illumination at the time point corresponding to the next adjustment step, until the illumination of the interior lamp reaches the target color temperature value Sxq and the target illumination value Zxq; if reached, stop triggering the execution instruction, and send the several smooth color temperature values ​​Zph and the several smooth illumination values ​​Zzh to the database for storage, so as to provide data reference for subsequent dimming of the same type of cultural relics.

[0049] In this embodiment, by sorting and gradually executing several smooth color temperature values ​​Zph and smooth illuminance values ​​Zzh, the accuracy and continuity of light adjustment are ensured. By arranging the generated data columns in ascending order, it is possible to gradually determine whether the color temperature and illuminance at each time point reach the target values ​​Sxq and Zxq, and automatically trigger the execution instruction when the target value is not reached, and send the execution instruction to the next adjustment step to execute the color temperature and illuminance at the time point corresponding to the next adjustment step until the target light state is finally reached. This step-by-step execution logic not only avoids the sudden change phenomenon in light adjustment, but also ensures the smoothness and stability of the light change process. The execution process has a strong dynamic response capability and can adjust the light to the optimal state required by the cultural relics in real time. At the same time, the generated adjustment data is saved in the database, providing a reliable reference for the subsequent dimming of cultural relics of the same category. This design reduces repeated calculations and manual intervention, improves the efficiency and reliability of system operation, and optimizes the execution logic of light adjustment. It not only improves the overall visual effect and audience experience of cultural relics display, but also shows advantages in energy saving, environmental protection and ease of operation, and provides strong technical support for the intelligent light management of multimedia showcases.

Finally, determine whether the smoothed color temperature value Zph and the smoothed illuminance value Zzh reached at the time point corresponding to each adjustment step reach the target color temperature value Sxq and the target illuminance value Zxq. If not, trigger the execution instruction to execute the color temperature and illuminance at the time point corresponding to the next adjustment step until the interior lighting reaches the target color temperature value Sxq and the target illuminance value Zxq.

[0051] In this embodiment, through sensor deployment, personnel activity warning, cultural relics identification, dynamic lighting adjustment and execution of multi-step design, the full process of intelligent cultural relics display cabinet lighting management is realized. Through high-definition cameras, ultrasonic sensors and AI target detection algorithms, the intention of personnel approaching is judged in real time and a warning signal is issued; after receiving the warning signal, the network crawler technology and light sensor data are combined to accurately match the lighting requirements of the cultural relics, dynamically generate target lighting parameters, and use the linear difference algorithm to generate smooth color temperature values ​​and illuminance values ​​to ensure the gradual transition of the light from the current state to the target state without sudden changes. Finally, through the gradual execution of the adjustment instructions, the lighting adjustment process is perfectly matched with the cultural relics needs. At the same time, the adjustment data is stored to provide an optimization basis for subsequent similar scenes.
