[0029] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0030] Please see Figure 1 and Figure 2 , Figure 1 This is a flowchart of the adaptive lighting method based on environmental perception provided in an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating an application scenario of the adaptive lighting adjustment method based on environmental perception provided in this embodiment of the invention. This method is applied to a control terminal 10, which is communicatively connected to both an IoT sensor 20 and a lighting fixture 30. The devices can be connected via wired or wireless communication through an IoT gateway device. The IoT sensor 20 includes a thermopile sensor 21 and an audio sensor 22. Typically, one lighting fixture 30 and at least one IoT sensor 20 are configured indoors. The adaptive lighting adjustment method is executed by application software installed in the control terminal 10. The control terminal 10 is the terminal device used to execute the adaptive lighting adjustment method based on environmental perception, adaptively adjusting and controlling the lighting fixture based on collected environmental detection information. The control terminal 10 may be an MCU control chip, FPGA logic circuit, etc., integrated on one side of the IoT gateway device. Figure 1 As shown, the method includes steps S110 to S150.

[0031] S110. If an activation message is received, an activation control command is sent to the lamp.

[0032] Users can input activation information into the control terminal. Upon receiving the activation information, the control terminal can send a corresponding activation control command to the lamp to turn it on. At this time, the lamp operates at the default brightness and default color temperature, for example, the default brightness is 70% of the maximum brightness and the default color temperature is 6500K (K is the unit of color temperature, Kelvin).

[0033] S120. Obtain the environmental detection information collected by the IoT sensor, and determine whether the environmental detection information meets the preset adjustment conditions.

[0034] Furthermore, the system acquires environmental detection information collected by IoT sensors. The control terminal can control the IoT sensors to periodically collect environmental detection information. For example, if the information collection cycle is configured to be 2 minutes in the control terminal, a set of environmental detection information will be collected every 2 minutes. The duration covered by a set of environmental detection information can be 5-20 seconds. For example, if the coverage duration can be set to 10 seconds, then the environmental information sensed within 10 seconds will be collected as a set of environmental detection information. The environmental detection information includes thermopile sensing information collected by the thermopile sensor and audio sensing information collected by the audio sensor. The system determines whether the acquired environmental detection information meets the preset adjustment conditions. If the adjustment conditions are met, the lighting fixtures will be adjusted; if the adjustment conditions are not met, the lighting fixtures will not be adjusted.

[0035] In one embodiment, step S120 specifically includes the following sub-steps: determining whether the thermopile sensing information in the environmental detection information meets the temperature judgment condition in the adjustment conditions; determining whether the audio sensing information in the environmental detection information meets the audio judgment condition in the adjustment conditions; if the temperature judgment condition or the audio judgment condition is met, determining that the environmental detection information meets the adjustment conditions; if neither the temperature judgment condition nor the audio judgment condition is met, determining that the environmental detection information does not meet the adjustment conditions.

[0036] First, it can be determined whether the thermopile sensing information in the environmental monitoring data meets the temperature judgment condition in the adjustment conditions. The thermopile sensing information is a monitoring map used to reflect the temperature at various points in the space environment. The thermopile information includes temperature detection values ​​at multiple points and multiple time points. The maximum temperature detection value is obtained by acquiring the maximum temperature detection value from the thermopile information, and then it is determined whether this maximum temperature detection value is greater than the temperature judgment threshold set in the temperature judgment condition. If the maximum temperature detection value is greater than the temperature judgment threshold, then the thermopile information is determined to meet the temperature judgment condition.

[0037] Further, it is determined whether the audio sensing information in the environmental detection information meets the audio judgment conditions in the adjustment conditions. The audio sensing information is the sensing information used to reflect the sound characteristics in the environment. The average loudness and maximum loudness of the audio sensing information are obtained, and it is determined whether the average loudness is greater than the average loudness threshold set in the audio judgment conditions, and whether the maximum loudness is greater than the maximum loudness threshold set in the audio judgment conditions. If the average loudness is greater than the average loudness threshold, or the maximum loudness is greater than the maximum loudness threshold, then the audio sensing information is determined to meet the audio judgment conditions. If the average loudness is not greater than the average loudness threshold, and the maximum loudness is not greater than the maximum loudness threshold, then the audio sensing information is determined not to meet the audio judgment conditions.

[0038] If the temperature or audio judgment condition is met, the environmental detection information is determined to meet the adjustment conditions, and the adjustment of the lamps is triggered. If neither the temperature nor the audio judgment condition is met, the environmental detection information is determined to not meet the adjustment conditions, and the adjustment of the lamps is not triggered.

[0039] In one embodiment, after step S120, the method further includes the step of: if the adjustment conditions are not met, sending a low-power operation command or a shutdown control command to the lamp.

[0040] If the adjustment conditions are not met, it indicates that there is no human activity in the current environment, or that people are in a resting state (such as being asleep or resting with their eyes closed). In this case, a low-power operation command or a shutdown command can be sent to the lamps to achieve energy-saving operation of the lamps and improve the energy-saving application effect of the lamps.

[0041] S130. If the adjustment conditions are met, the environmental detection information is analyzed according to the preset analysis rules to obtain the corresponding environmental analysis features.

[0042] If the adjustment conditions are met, the environmental monitoring information can be analyzed according to the analysis rules to obtain environmental analysis features. Since the environmental monitoring information includes thermopile induction information and audio induction information, it is necessary to analyze the thermopile induction information and audio induction information separately to obtain the corresponding environmental analysis features. These environmental analysis features can then be used to characterize the activities of personnel in the current environment.

[0043] In one embodiment, step S130 specifically includes the following sub-steps: parsing the thermopile sensing information in the environmental detection information according to the thermopile parsing model in the parsing rules to obtain the corresponding temperature parsing features; parsing the audio sensing information in the environmental detection information according to the audio parsing model in the parsing rules to obtain the corresponding audio parsing features; and combining the temperature parsing features with the audio parsing features to obtain the corresponding environmental parsing features.

[0044] First, the thermopile-induced information can be analyzed using the thermopile analytical model in the analytical rules to obtain temperature analytical features. These features can be used to reflect the level of physical activity of people in the current environment. Next, the audio-induced information can be analyzed using the audio analytical model in the analytical rules to obtain corresponding audio analytical features. These features are used to reflect the emotional state of people's speech in the current environment. Combining the obtained temperature and audio analytical features yields the corresponding environmental analytical features.

[0045] In one embodiment, the step of parsing the thermopile sensing information in the environmental detection information according to the thermopile analysis model in the analysis rules to obtain the corresponding temperature analysis features includes: binarizing the thermopile sensing information according to the temperature analysis parameters in the thermopile analysis model to obtain the corresponding binarized information; and extracting the feature parameters corresponding to each temperature feature item from the binarized information according to the temperature feature items in the thermopile analysis model, as the temperature analysis features.

[0046] Specifically, the thermopile induction information can be binarized based on the temperature analysis parameters in the thermopile analytical model. The thermopile induction information includes thermopile induction maps corresponding to multiple time points. The temperature analysis parameters include a reference temperature range. It can be determined whether the temperature value of each point in the thermopile induction map falls within the reference temperature range. If it does, the value of that point is set to "1"; if it does not, the value is set to "0". By determining the value of each point, the thermopile induction information is binarized, resulting in binarized information corresponding to each thermopile induction map. The reference temperature range matches human body temperature; for example, it can be set to [35.2℃, 37.9℃]. The thermopile analytical model contains multiple temperature feature terms. Further, feature parameters corresponding to each temperature feature term are extracted from the binarized information based on these temperature feature terms, serving as temperature analysis features. Each temperature feature term corresponds to one feature parameter. If the temperature feature includes the percentage of effective sites and the percentage of sites changing, then the percentage of sites with a value of "1" in the binarized information of each thermopile induction map can be obtained and the average value calculated to obtain the feature parameter corresponding to the percentage of effective sites. Further, the number of changing sites in the binarized information of adjacent thermopile induction maps can be obtained. If the value of the same site in the binarized information of adjacent thermopile induction maps changes from "0" to "1" or from "1" to "0", then that site is determined to be a changing site, and the corresponding number of changing sites is counted. If there are n thermopile induction maps, then there are n-1 sets of changing sites. The ratio between the number of changing sites and the total number of sites in a single thermopile induction map is calculated and the average value is calculated to obtain the feature parameter corresponding to the percentage of sites changing. Combining the feature parameters corresponding to each temperature feature yields the temperature analytical feature.

[0047] In one embodiment, the step of parsing the audio sensing information in the environmental detection information according to the audio parsing model in the parsing rules to obtain the corresponding audio parsing features includes: filtering the audio sensing information according to a preset audio segment in the audio parsing model to obtain valid audio corresponding to the preset audio segment; and extracting feature parameters corresponding to each audio feature item from the valid audio according to the audio feature items in the audio parsing model, as the audio parsing features.

[0048] The audio parsing model has preset audio segments, which can be used to filter audio sensing information. This means that audio information within the preset audio segments is selected as the filtered, valid audio. The audio sensing information includes audio information corresponding to each audio frequency. For example, if the preset audio segment is set to [200Hz, 4000Hz], then audio information with frequencies within that preset audio segment can be selected as valid audio.

[0049] Furthermore, based on the audio feature terms in the audio analysis model, the feature parameters corresponding to each audio feature term are obtained in advance from the effective audio. For example, audio feature terms include timbre features, loudness features, and speech rate features. The mean loudness of the effective audio can be obtained as the feature parameter corresponding to the loudness feature. The speech duration and number of words in the effective audio can be obtained, and the ratio between the number of words and the speech duration can be calculated to obtain the feature parameter corresponding to the speech rate feature. Specifically, the Mel-spectral features of the effective audio can be extracted, and speech recognition can be performed on the Mel-spectral features to obtain text information. Based on the text information, the number of words and the corresponding speech duration can be determined. The loudness of each frequency band in the effective audio can be obtained, and the ratio between the loudness of each frequency band can be calculated to obtain the corresponding timbre feature ratio, which is used as the feature parameter corresponding to the timbre feature. For example, multiple frequency bands can be set: low frequency band [200Hz, 599Hz], mid frequency band [600Hz, 1499Hz], mid-high frequency band [1500Hz, 2799Hz], and high frequency band [2800Hz, 4000Hz]. The audio loudness of each frequency band in the effective audio can then be obtained as P1, P2, P3, and P4, respectively. Furthermore, the timbre feature ratios can be obtained as P1 / P2, P1 / P3, P1 / P4, P2 / P3, P2 / P4, and P3 / P4, respectively. Combining the feature parameters corresponding to each audio feature item yields the corresponding audio analytical features.

[0050] S140. Obtain the adjustment configuration parameters corresponding to the environmental analysis features according to the preset configuration model.

[0051] Furthermore, the adjustment configuration parameters corresponding to the environmental analysis characteristics can be obtained based on the configuration model, that is, the configuration parameters that match the environmental analysis characteristics and are used for lighting adjustment control can be obtained.

[0052] In one embodiment, step S140 specifically includes the following sub-steps: identifying the environmental parsing features according to the environmental identification rules in the configuration model to obtain the corresponding environmental feature parameters; and performing parameter configuration mapping on the environmental feature parameters according to the mapping rules in the configuration model to obtain the corresponding adjustment configuration parameters.

[0053] Specifically, the environmental features can be identified according to environmental recognition rules to obtain corresponding environmental feature parameters. The environmental recognition rules can be based on a neural network constructed using artificial intelligence. These rules can be configured with an input layer, an intermediate layer, and an output layer. The input layer includes multiple input nodes, each intermediate layer has multiple intermediate nodes, and the environmental recognition rule can have one or more intermediate layers. The output layer includes multiple output nodes. There is a correlation formula between the input nodes and the intermediate nodes of the first intermediate layer, between the intermediate nodes of adjacent intermediate layers, and between the output nodes and the intermediate nodes of the last intermediate layer. Each input node in the input layer corresponds to a feature parameter in the input environmental features. The intermediate layers perform correlation analysis on the input feature parameters, and the corresponding result is output from the output layer. The output layer can be configured with two output nodes, each outputting a feature value. For example, one output node might output a feature value corresponding to an activity coefficient; a higher activity coefficient indicates higher physical activity. The other output node might output a feature value corresponding to an emotion coefficient; a higher emotion coefficient indicates more excited vocal emotions. The two obtained feature values ​​are both in the range of [0,1]; the feature values ​​of the two output nodes can be combined as the corresponding environmental feature parameters.

[0054] Before using environmental recognition rules, they can be trained. Specifically, a training dataset based on historical data can be constructed to train the environmental recognition rules. For example, multiple sets of environmental parsing features can be obtained from historical data, along with user-reported physical activity scores and voice emotion scores from questionnaires. The physical activity scores are converted into corresponding target activity coefficients, and the voice emotion scores are converted into corresponding target emotion coefficients. Each set of environmental parsing features, along with the corresponding target activity coefficient and target emotion coefficient, forms a training data point in the training dataset. The training data is then input into the environmental recognition rules, and the output activity coefficients and emotion coefficients are obtained. Gradient descent is performed based on the differences between the target activity coefficients and target emotion coefficients and the actual activity coefficients and emotion coefficients, thereby adjusting the parameters of the association formula in the environmental recognition rules in reverse, achieving iterative training. The environmental recognition rules obtained after training are then used for recognition applications.

[0055] Furthermore, the configuration model also includes mapping rules, which in turn include a pattern mapping table. This table contains multiple adjustment modes, each corresponding to a set of parameter ranges (e.g., an activity range [0.5, 0.75], an emotion range [0.3, 0.6]). The obtained environmental feature parameters can be compared with the parameter ranges in the pattern mapping table to obtain the adjustment mode corresponding to the parameter range that matches the environmental feature parameters, thus identifying the target adjustment mode. The target adjustment mode includes target brightness, base color temperature, and adjustment interval time, among other parameters.

[0056] Furthermore, the mapping rules also include an adjustment range function and a rate of change function. The adjustment range function determines the color temperature adjustment range corresponding to the environmental characteristic parameters and the base color temperature, while the rate of change function determines the rate of change corresponding to the environmental characteristic parameters. The ratio of the activity coefficient to the natural constant in the environmental characteristic parameters can be calculated based on the adjustment range function. This ratio is then raised to the power of the natural constant and subtracted by one. The difference is divided by two to obtain the corresponding adjustment coefficient r. Based on the adjustment coefficient r, the corresponding adjustment interval [1-r, 1+r] can be determined. The lower and upper limits of the adjustment interval are multiplied by the base color temperature, and the resulting products are set as the upper and lower limits of the color temperature adjustment range, thus obtaining the color temperature adjustment range corresponding to the environmental characteristic parameters and the base color temperature. The color temperature adjustment range shall not exceed the preset color temperature range of the lamp. If the upper limit of the interval in the obtained product result exceeds the preset color temperature range, the maximum value of the preset color temperature range shall be used as the upper limit of the color temperature adjustment range. If the lower limit of the interval in the obtained product result exceeds the preset color temperature range, the minimum value of the preset color temperature range shall be used as the lower limit of the color temperature adjustment range.

[0057] The product of the activity coefficient and the emotion coefficient in the environmental characteristic parameters is calculated based on the rate of change function. The square root of this product is then calculated, raised to the power of the natural constant, and multiplied by the preset rate coefficient to obtain the final product value. The difference between the maximum and minimum values ​​within the preset color temperature range is used to calculate the corresponding adjustment difference. Dividing this adjustment difference by the product value gives the set rate of change. Combining the obtained target adjustment mode with the color temperature adjustment range and rate of change yields the corresponding adjustment configuration parameters.

[0058] S150. Send the corresponding adjustment control command to the lamp according to the adjustment configuration parameters to adjust the lamp.

[0059] Based on the obtained adjustment configuration parameters, corresponding adjustment control commands are sent to the luminaires to adjust their brightness. Specifically, a brightness adjustment control command can be sent to the luminaires based on the target brightness in the adjustment configuration parameters to adjust the brightness of the luminaires, and a corresponding color temperature adjustment control command can be sent to the luminaires based on the color temperature adjustment range and rate of change to adjust the color temperature of the luminaires; the interval between sending the two sets of color temperature adjustment control commands is equal to the adjustment interval time set in the adjustment configuration parameters.

[0060] After a preset information collection period, the process can return to step S120. If a shutdown message is received, a shutdown command can be sent to the light fixture to control it to turn off, thereby achieving energy-saving effects.

[0061] The adaptive lighting adjustment method based on environmental perception provided in this invention includes: an adaptive lighting adjustment method and apparatus based on environmental perception. The method includes: upon receiving an activation information, sending an activation control command to the lighting fixture; acquiring environmental detection information collected by an IoT sensor and determining whether adjustment conditions are met; if met, parsing the environmental detection information and obtaining adjustment configuration parameters corresponding to the parsed environmental features; and sending corresponding adjustment control commands to the lighting fixture according to the adjustment configuration parameters to adjust the lighting fixture.

The method includes: an environmentally-aware adaptive lighting method and device. The method includes: upon receiving an activation information, sending an activation control command to the lighting fixture; acquiring environmental detection information collected by an IoT sensor and determining whether adjustment conditions are met; if met, parsing the environmental detection information and obtaining adjustment configuration parameters corresponding to the parsed environmental features; and sending corresponding adjustment control commands to the lighting fixture according to the adjustment configuration parameters to adjust the lighting fixture.
