After using convolutional neural networks (CNN) to build emotion recognition models, the emotion index Em is constructed.

[0067] The present invention provides an atmosphere light adaptive management method and system based on emotion perception, which has the following beneficial effects:
[0068] (1) Traditional lighting systems are difficult to meet the personalized needs of different employees. However, the present invention can adjust the brightness of the light in real time according to the emotional state of the employee by combining the emotion perception model and the environmental simulation model. When the system detects that the employee's emotional index Em is lower than the set threshold E, it will automatically generate an early warning instruction and adjust the light accordingly according to the light brightness coefficient Ll. In this way, the light can not only provide a comfortable working environment for employees with low moods, but also help improve the employees' concentration and emotional state through appropriate light adjustment.
[0069] (2) The present invention not only effectively avoids low work efficiency caused by excessive or insufficient light, but also maximizes the use of natural light, reduces energy consumption, and improves environmental protection effects. By combining the real-time emotional state of employees and external environmental conditions, the system can adaptively provide suitable lighting solutions for different areas (such as conference rooms, personal office areas, and rest areas). When it is detected that the employee's emotional index Em is lower than the threshold and his concentration decreases, the system calculates the comprehensive emotional lighting adjustment coefficient Cl to generate an atmosphere light adjustment instruction suitable for the current scene to help employees recover and improve work efficiency. For example, in the meeting area, when the system senses that the participants are emotionally fluctuating or tired, the light will automatically adjust to cool light. Cold light can reduce the impact of emotional fluctuations and help participants concentrate; in the rest area, warm light helps create a relaxing and warm atmosphere to help employees recover their emotions and energy.
[0070] (3) Traditional lighting systems cannot effectively perceive changes in employees' status, while the intelligent early warning mechanism of the present invention can generate early warning instructions and adjust the lighting environment in a timely manner by evaluating the emotional index Em when employees are in low mood or concentration. The system not only creates a comfortable working atmosphere through mood lighting adjustment, but also can evaluate the comprehensive emotional lighting adjustment coefficient Cl in real time to ensure that the lighting adjustment can accurately match the current scene requirements and provide employees with the most suitable lighting environment.
[0071] (4) Depending on the difference between the first warning instruction and the second warning instruction, the adjustment instructions generated by the system are also different. The first warning instruction generally reflects a slight emotional fluctuation, so the lighting adjustment amplitude is smaller; while the second warning instruction is aimed at a more significant drop in emotion, and the lighting adjustment is more active and larger. This hierarchical response mechanism ensures precise intervention in emotional fluctuations, can provide appropriate lighting support to participants in a timely manner, and effectively alleviate fatigue and inattention during meetings.

When the emotion index Em is lower than the emotion threshold E, it indicates that the current employee's emotional state and concentration are not up to standard, and a corresponding warning instruction is generated, and the light brightness coefficient Ll is associated to calculate the comprehensive emotion light adjustment coefficient Cl;
[0080] S4. After receiving the corresponding warning instruction, the comprehensive emotional lighting adjustment coefficient Cl is evaluated, and corresponding atmosphere light adjustment instructions are generated according to different scenes to adapt to the current emotions and scene requirements.
[0081] In this embodiment, the traditional lighting system is difficult to meet the personalized needs of different employees, but the present invention can adjust the brightness of the light in real time according to the emotional state of the employee through the combination of the emotion perception model and the environmental simulation model. When the system detects that the employee's emotional index Em is lower than the set threshold E, it will automatically generate an early warning instruction and adjust the light accordingly according to the light brightness coefficient Ll. In this way, the light can not only provide a comfortable working environment for employees with low moods, but also help improve the concentration and emotional state of employees through appropriate light adjustment.

When the outdoor light intensity and weather conditions change, the system can adjust the indoor light intensity in time through the environmental simulation model to achieve dynamic linkage with the external environment. Compared with traditional lighting systems, the present invention not only effectively avoids low work efficiency caused by excessive or insufficient light, but also maximizes the use of natural light, reduces energy consumption, and improves environmental protection effects.
[0083] By combining the real-time emotional state of employees and external environmental conditions, the system can adaptively provide appropriate lighting solutions for different areas (such as conference rooms, personal office areas, and rest areas). When it is detected that the employee's emotional index Em is lower than the threshold and the concentration is reduced, the system calculates the comprehensive emotional lighting adjustment coefficient Cl to generate an atmosphere light adjustment instruction suitable for the current scene to help employees recover and improve work efficiency. For example, in the meeting area, when the system senses that the participants are emotionally fluctuating or tired, the light will automatically adjust to cool light, which can reduce the impact of emotional fluctuations and help participants concentrate; in the rest area, warm light helps create a relaxing and warm atmosphere to help employees restore their emotions and energy.
[0084] Traditional lighting systems cannot effectively perceive changes in employees' status, but the intelligent early warning mechanism of the present invention can generate early warning instructions and adjust the lighting environment in a timely manner through the evaluation of the emotional index Em when employees are in low mood or concentration. The system not only creates a comfortable working atmosphere through the adjustment of the mood light, but also can evaluate the comprehensive emotional lighting adjustment coefficient Cl in real time to ensure that the lighting adjustment can accurately match the current scene requirements and provide the most suitable lighting environment for employees.

[0121] S32, combining the emotion index Em and the light brightness coefficient Ll, after dimensionless processing, the comprehensive emotion light adjustment coefficient Cl is calculated by the following formula:
[0122] ;
[0123] In the formula, E represents the emotion threshold, and Represents the weight coefficient. , , ;
[0124] In this embodiment, by comparing the employee's emotional index Em with the preset emotional threshold E, it is possible to effectively judge whether the employee's emotional state and concentration meet the standard. This precise judgment mechanism can detect changes in employee emotions in a timely manner, especially when emotional concentration is insufficient, the system will issue different levels of early warning instructions according to different emotional indexes. The first early warning instruction is used to prompt the situation where concentration is slightly unqualified, and the environment can be improved by adjusting the brightness of the light. The second early warning instruction is used for more serious concentration decline, and the system will intervene more strongly to help employees restore their concentration. This multi-level early warning mechanism ensures that the system responds sensitively to employee emotional fluctuations and improves the comfort and efficiency of the working environment. By calculating the comprehensive emotional lighting adjustment coefficient Cl through the formula, it can not only comprehensively consider the employee's emotional state and the current lighting conditions, but also intelligently adjust the lighting intensity in different situations. The introduction of this adjustment coefficient can make lighting control more personalized and precise, thereby optimizing the lighting environment to adapt to the different emotional states of employees.
[0125] Example 5
[0126] This embodiment is an explanation of the embodiment 1. Specifically, after receiving the first warning instruction and the second warning instruction, when it is determined that the area is a meeting area, the comprehensive emotional lighting adjustment coefficient Cl is evaluated to obtain the corresponding atmosphere light adjustment instruction, including:
[0127] When the current scene requirement is a meeting discussion scene, when the first warning instruction is generated and the comprehensive emotional lighting adjustment coefficient Cl ≥ the first meeting brightness threshold Q1, the first atmosphere light adjustment instruction is generated to increase the current area light brightness by 1%-5% lumens and adjust it to a cold light of 4000K;
[0128] If the comprehensive emotional lighting adjustment coefficient Cl is less than the first meeting brightness threshold Q1, a second atmosphere light adjustment instruction is generated to increase the current area light brightness by 1%-5% lumens and adjust it to a cool light of 4500K;
[0129] When the current scene requirement is a meeting discussion scene, when the second warning instruction is generated and the comprehensive emotional lighting adjustment coefficient Cl ≥ the first meeting brightness threshold Q1, the third atmosphere light adjustment instruction is generated to increase the current area light brightness by 3%-8% lumens and adjust it to a cool light of 5000K;
[0130] If the comprehensive emotional lighting adjustment coefficient Cl is less than the first meeting brightness threshold Q1, a fourth atmosphere light adjustment instruction is generated to enhance the current area lighting by 9%-14% lumen brightness and adjust the lighting to a cool light of 5500K.
[0131] In this embodiment, the light brightness and color temperature can be flexibly adjusted according to the current scene requirements (such as meeting discussion scenes). By generating different atmosphere light adjustment instructions, the system can provide accurate light adjustment for different degrees of emotional warning. This scene-based adaptive adjustment makes lighting control more intelligent, which helps to improve employees' concentration and discussion efficiency in meetings, especially adjusting different lighting environments at different stages, which can better support the smooth progress of meetings.
[0132] The light brightness is adjusted in a gradual enhancement mode (such as 1%-5%, 3%-8%, etc.), avoiding discomfort to participants caused by sudden brightness changes. This gradual adjustment can effectively reduce visual fatigue and help employees maintain their attention during long meetings. In addition, combined with the gradual adjustment of cool light, it can provide participants with a clearer and brighter visual environment, which is suitable for meeting discussions that require concentration.
[0133] After receiving the early warning instruction, the system evaluates the comprehensive emotional lighting adjustment coefficient Cl and reasonably generates adjustment instructions of different brightness and color temperature to ensure that the lighting adjustment can better respond to the current emotional state and lighting needs. For example, when Cl is high, the light adjustment range is small to avoid over-stimulation; when Cl is low, the light intensity is increased to activate the attention of employees.
[0134] This intelligent adjustment mechanism ensures that the lighting changes more closely match the actual needs under different emotional states. The system helps employees maintain a higher level of concentration by adjusting the light color temperature to cool light ranges such as 4000K, 4500K, 5000K and 5500K. Cool light usually stimulates brain activity, making employees more awake and focused, and is particularly suitable for occasions that require efficient interaction, such as conference discussions. Through different levels of cool light adjustment, the system can provide the best lighting environment according to the employee's state, helping employees overcome fatigue and improve the productivity of meetings.
[0135] Depending on the difference between the first warning instruction and the second warning instruction, the adjustment instructions generated by the system are also different. The first warning instruction generally reflects a slight mood swing, so the lighting adjustment is smaller; while the second warning instruction is aimed at a more significant mood drop, and the lighting adjustment is more active and larger. This hierarchical response mechanism ensures precise intervention in mood swings, can provide appropriate lighting support to participants in a timely manner, and effectively alleviate fatigue and inattention during meetings.
[0136] Example 6
[0137] This embodiment is an explanation of the embodiment 1. Specifically, after receiving the first warning instruction and the second warning instruction, when it is determined that the person is in the personal work area, the comprehensive emotional lighting adjustment coefficient Cl is evaluated to obtain the corresponding atmosphere light adjustment instruction, including:
[0138] When the current scene requirement is a personal work scene, when the first warning instruction is generated and the comprehensive emotional lighting adjustment coefficient Cl ≥ the second brightness threshold Q2, the fifth atmosphere light adjustment instruction is generated to enhance the current area light by 9%-14% lumen brightness and adjust to warm light of 3500K;
[0139] If the comprehensive emotional lighting adjustment coefficient Cl is less than the second brightness threshold Q2, a sixth ambient light adjustment instruction is generated to increase the current area light brightness by 9%-14% lumens and adjust the light to a cool color of 4000K;
[0140] When the current scene requires a personal work scene, when the second warning instruction is generated and the comprehensive emotional lighting adjustment coefficient Cl ≥ the second brightness threshold Q2, the seventh atmosphere light adjustment instruction is generated to increase the current area light brightness by 5%-6% lumens and adjust it to warm light of 3500K;
[0141] If the comprehensive emotional lighting adjustment coefficient Cl is less than the second brightness threshold Q2, the eighth atmosphere light adjustment instruction is generated to enhance the brightness of the light in the current area by 7%-8% lumens and adjust it to a cool light of 4000K.
[0142] In this embodiment, the system can flexibly adjust the brightness and color temperature of the light according to the needs of individual work scenes. When an early warning instruction is generated, the adjustment of the light is not only based on the emotional index Em, but also combined with the changes in the light adjustment coefficient Cl to accurately match the current work status of the employee. Through different atmosphere light adjustment instructions (such as warm or cold light), the comfort of the personal work area can be enhanced, which helps employees get better lighting support when they are focused on their work. The system has designed different light color temperature adjustment schemes: when Cl is higher than the second brightness threshold Q2, the system tends to use warm light (3500K) to create a comfortable environment and help employees relax; when Cl is lower than Q2, the system automatically switches to cold light (4000K) to stimulate employees' attention and alertness. This reasonable switching between warm and cold colors can effectively adjust the emotional state of employees and help them maintain optimal concentration and emotional balance at work.
[0143] Example 7
[0144] This embodiment is an explanation of the embodiment 1. Specifically, after receiving the first warning instruction and the second warning instruction, when it is determined that the area is in the rest area, the comprehensive emotional lighting adjustment coefficient Cl is evaluated to obtain the corresponding atmosphere light adjustment instruction, including:
[0145] When the current scene requirement is a leisure lunch break scene, when the first warning instruction is generated and the comprehensive emotional lighting adjustment coefficient Cl ≥ the third brightness threshold Q3, the ninth atmosphere light adjustment instruction is generated to reduce the current area light by 31%-40% lumen brightness and adjust it to warm light of 2700K;
[0146] If the comprehensive emotional lighting adjustment coefficient Cl is less than the third brightness threshold Q3, a tenth ambient light adjustment instruction is generated to reduce the current area light by 21%-30% lumen brightness and adjust it to a warm light of 3000K;
[0147] When the current scene requires a leisure lunch break scene, when the second warning instruction is generated and the comprehensive emotional lighting adjustment coefficient Cl ≥ the third brightness threshold Q3, the eleventh atmosphere light adjustment instruction is generated to reduce the current area light by 16%-20% lumen brightness and adjust it to warm light of 2700K;
[0148] If the comprehensive emotional lighting adjustment coefficient Cl is less than the third brightness threshold Q3, the twelfth ambient light adjustment instruction is generated to reduce the current area light by 10%-15% lumen brightness and adjust it to warm light of 3000K.
[0149] In this embodiment, the system can accurately identify the current scene as a leisure lunch break scene and flexibly adjust the light brightness and color temperature. By reducing the light brightness and adjusting it to warm light, a soft and comfortable environment is created, which helps employees relax during breaks and improves the overall balance between work and rest. Warm light adjustment schemes with different brightness are set, such as 2700K and 3000K color temperature selections to simulate the warm effect of natural light. Lower color temperatures help relax the brain, relieve fatigue, and improve the quality of employees' lunch breaks, which is conducive to improving work efficiency after rest. The system is divided into multiple brightness adjustment levels based on the changes in the comprehensive emotional lighting adjustment coefficient Cl. Under the first warning instruction, the light brightness decreases by a large margin (31%-40% or 21%-30%), helping employees quickly enter a relaxed state; while under the second warning instruction, the brightness adjustment range is relatively small (16%-20% or 10%-15%), avoiding excessive dimming while providing a moderate rest environment. This multi-level adjustment ensures that the system can flexibly adjust the light according to emotional state and environmental requirements to adapt to different rest needs. In the rest area, the system automatically generates adjustment instructions by monitoring the emotional state of employees and changes in ambient light in real time, so that the lighting adjustment process does not require manual intervention. This intelligent adjustment method reduces external interference during the rest process and provides a more peaceful and comfortable rest environment.
