Description

A remote monitoring method and system for laser agricultural lighting Technical Field

[0001] This invention relates to the field of remote monitoring technology, and in particular to a remote monitoring method and system for laser agricultural lighting. Background Technology

[0002] The field of remote monitoring technology for laser agricultural lighting encompasses a technical system for remotely collecting and managing the operational status of agricultural lighting equipment. The core of this technology involves real-time monitoring and control of the operating parameters of agricultural lighting sources via network connectivity. Monitoring is based on factors such as light source emission characteristics, illumination period segments, and light intensity adjustment benchmarks. This is combined with analysis and management of environmental sensor data and equipment operating sequence. This field typically involves recording equipment operating status, configuring illumination periods, collecting light output values, identifying abnormal states, and issuing remote management commands, forming an information management framework for monitoring and adjusting the operational status and parameters of agricultural lighting.

[0003] One method for remote monitoring of laser agricultural lighting refers to a technical solution for remotely observing, recording, and controlling the operating status of agricultural laser lighting equipment. It mainly covers setting the illumination cycle, inputting the light intensity setpoint, comparing and judging ambient light, collecting equipment working signals, uploading lighting status, and executing remote control commands. It uses the measured value of the laser source luminous intensity, the recorded equipment operating time period, the ambient brightness sensor value, and the user input commands as the basis for execution. It generally completes the remote monitoring and parameter management process of laser agricultural lighting equipment through remote data reporting, command feedback, equipment-side circuit drive execution, storage and comparison of illumination parameters, and reading of environmental monitoring data.

[0004] Existing technologies rely primarily on fixed illumination parameters and time periods, lacking dynamic analysis of multi-dimensional illumination data. They cannot accurately capture changes in illumination direction and their associated characteristics. Because they depend solely on single-point light intensity or ambient brightness comparisons, they fail to reflect the true distribution of light energy. Under environmental changes or equipment fluctuations, control delays and imbalances easily occur. Existing methods lack mechanisms for judging energy differentiation between wavelengths and for real-time response, failing to match illumination based on differences in plant absorption. This results in low lighting efficiency, amplified regional differences, insufficient accuracy in light distribution, and overall lagging monitoring feedback. Summary of the Invention

[0005] To address the technical problems existing in the prior art, this invention provides a remote monitoring method and system for laser agricultural lighting. The technical solution is as follows: A remote monitoring method for laser agricultural lighting includes the following steps: S1: Acquire the power signal, illuminance value, and plant reflected light intensity data of the laser illuminator in the lighting area; record and compare the direction of change over time; sort and label the levels according to the magnitude of the amplitude; compare the power and illuminance trajectories; integrate the comparison results into a regional fluctuation trajectory; and generate a light fluctuation sequence record table; S2: Based on the direction and level labels in the light fluctuation sequence record table, perform combination rule judgment on the power, illuminance, and reflection direction to determine the plant light level; connect the time sequence labels in chronological order and associate them with the region number and time... S3: Based on the area number and time tag in the light monitoring status chain, call blue light, red light and near-infrared data to generate trend tags, compare the trend to select the main absorption band that corresponds to under-illumination and is continuously decreasing, associate the area and time tag, and generate a light absorption channel record table; S4: Based on the main channel band identifier in the light absorption channel record table, call the light energy curve under the main channel band, extract the peak and valley sequence to obtain the envelope direction tag, compare the envelope direction with the reference segment for consistency, adjust the signal if there is continuous offset, maintain the signal if it is alternately stable, and adjust the signal set for remote irradiation.

[0006] As a further embodiment of the present invention, the light fluctuation sequence record table includes laser output power signal, light sensor illuminance value, plant reflected light intensity data, direction label, level label, regional fluctuation trajectory, and time index; the light monitoring status chain includes over-illumination label, under-illumination label, stable-illumination label, power direction label, illuminance direction label, reflection direction label, level label, time label, and region number; the light absorption channel record table includes blue light trend label, red light trend label, near-infrared trend label, absorption channel band, region number, time label, and direction label; and the remote irradiation adjustment signal set includes envelope direction label, peak-valley sequence consistency, envelope displacement direction, adjustment signal type, signal triggering condition, region number, and time label.

[0007] As a further embodiment of the present invention, the steps for obtaining the light fluctuation sequence record table are as follows: S101: Obtain the power signal of the laser illuminator output terminal, the illuminance value of the light sensor, and the light intensity data of the reflected light from the plant within the illumination area. Record them in the order of sampling time and establish an index. Compare the power signal, illuminance value, and reflected light intensity at adjacent time points. When the value at a later time point is higher than that at a previous time point, mark it as upward; when it is lower, mark it as downward. Record the direction label for each data point and generate a direction determination result set; S102: According to the direction determination result set, calculate the change amplitude of the power signal, illuminance value, and reflected light intensity within the same sampling window. Sort them according to the amplitude size and label them as the first level, second level, or third level in sequence. Record the corresponding level label and organize them in combination with the time index and the area number to generate a level sorting result table; S103: According to the direction determination result set and the level sorting result table, compare the direction labels and level labels of power, illuminance, and reflected light intensity at the same time point to form a comprehensive change trajectory of each sampling point. Archive them according to the area number and time label to generate a light fluctuation sequence record table.

[0008] As a further embodiment of the present invention, the step of obtaining the illumination monitoring state chain is as follows: S201: Obtain the direction labels and level labels of power direction, illuminance direction and reflection direction in the illumination fluctuation sequence record table, compare the data at each time point, when both the power direction and illuminance direction are upward and the reflection direction is upward, check the level labels of power and illuminance, when both are at the first level, mark it as an over-illumination state, and write the corresponding time point into the state field to generate an over-illumination judgment result set; S202: Based on the over-illumination judgment result set, continue to check the power direction, illuminance direction and reflection direction... The comparison is performed. When the power direction and illuminance direction are both downward and the reflection direction is upward, the level label of the reflection direction is extracted. When the level is the first level, it is marked as under-illumination state. The results are written into the status field in chronological order to generate an under-illumination judgment result set. S203: Based on the over-illumination judgment result set and the under-illumination judgment result set, the time points where the power direction, illuminance direction and reflection direction are consistent are selected. When the corresponding level labels are all the second level or the third level, they are marked as stable illumination state. The three types of states are connected in chronological order and archived with the area number and time label to generate a light monitoring status chain.

[0009] As a further embodiment of the present invention, the acquisition step of the light absorption channel record table is as follows: S301: Obtain the area number and time tag in the light monitoring status chain, locate the monitoring segment according to the time tag, call the blue light, red light and near-infrared reflected light intensity records in the same area and the same time period, arrange the reflected light intensity values ​​of each band in chronological order, calculate the difference between adjacent sampling points, mark the difference as upward when the difference is positive, mark the difference as downward when the difference is negative, and record the direction tag to generate a band direction sequence; S302: According to the band direction sequence, assign directions to blue light, red light and near-infrared light respectively. The labels are arranged in chronological order to determine the continuity of directional changes within a continuous sampling segment. When the direction remains the same, it is marked as a unidirectional trend; when the direction changes alternately, it is marked as a fluctuating trend. The trend labels of the three bands are recorded by time index to generate a band trend result set. S303: The band trend result set is called, and the trend labels of blue light, red light, and near-infrared light are compared within the same time period. Bands that correspond to the under-illuminated state and show a continuous downward trend are selected. Their corresponding area numbers are extracted and matched with the time labels to establish the association record between the band and the monitoring segment and generate a light absorption channel record table.

[0010] As a further embodiment of the present invention, the step of acquiring the remote illumination adjustment signal set is as follows: S401: Acquire the main channel band identifier in the light absorption channel record table, retrieve the light energy change curve of each region under the corresponding band, align each sampling point according to the time label, extract the peak and valley positions of light energy in adjacent sampling segments, record the order of peak appearance and mark the direction of envelope direction, continuously record in the same region to form an envelope change record, and generate an envelope direction sequence; S402: Based on the envelope direction sequence, determine the envelope reference curve of the starting segment of the current monitoring cycle, and adjust the peak and valley arrangement order of subsequent sampling segments according to the envelope direction sequence. The network reference is compared, and the displacement difference between the upper and lower envelopes is calculated. When the peak and valley order is consistent and the displacement direction is the same, it is recorded as a consistent state. When the order is inconsistent or the displacement direction is opposite, it is recorded as an offset state, and an envelope consistency comparison result is generated. S403: The envelope consistency comparison result is called to judge the envelope direction label of the continuous sampling segment. When the envelope direction remains in the same direction in the continuous segment and is inconsistent with the reference, it is recorded as an offset signal. When the envelope direction alternates in the continuous segment and is consistent with the reference, it is recorded as a stable signal. The signals of each region are sorted and numbered in chronological order to generate a remote illumination adjustment signal set.

[0011] As a further embodiment of the present invention, the method further includes: S5: according to the signal type in the remote illumination adjustment signal set, calling the status label and the main channel band identifier, integrating the illumination status and absorption channel information of each region according to the continuous segment of area and time, summarizing the continuous adjustment signals in the same region, determining the adjustment direction according to the signal type, forming a dimming operation instruction list, and labeling the area number and direction to transmit to the remote monitoring terminal to generate monitoring results; the remote monitoring results include the dimming operation instruction list, adjustment direction, illumination status, absorption channel information, area number, main channel band identifier, and time segment identifier.

[0012] As a further embodiment of the present invention, the steps for obtaining the remote monitoring results are as follows: S501: Obtain the signal types in the remote illumination adjustment signal set, call the status labels in the illumination monitoring status chain and the main channel band identifier in the light absorption channel record table, organize them according to the area number and time label, match the signal types, illumination status and main channel bands in the same area, and merge the results according to the continuous time segment to generate an integrated regional illumination record; S502: According to the integrated regional illumination record, filter the adjustment signals that appear continuously in the same area under the same main channel, compare the directional changes of adjacent signal types, record the continuous signals with the same direction as "maintain", and record the signals with opposite directions as "adjust", classify them according to the upward and downward adjustment directions respectively, and generate a regional adjustment direction distribution; S503: Call the regional adjustment direction distribution, summarize the adjustment directions of each area with the continuous time segment, form the dimming operation command of the lighting area, label the adjustment direction and command information according to the area number, and transmit the results to the remote monitoring terminal to generate the remote monitoring results.

[0013] A remote monitoring system for laser agricultural lighting includes: a data acquisition module that acquires power signals, illuminance values, and plant reflected light intensity data of laser illuminators in the lighting area; records and compares the direction of change over time; sorts and labels the levels according to the magnitude of the change; compares the power and illuminance trajectories; integrates the comparison results into a regional fluctuation trajectory; and generates a light fluctuation sequence record table. A state recognition module, based on the direction and level labels in the light fluctuation sequence record table, performs combination rule judgments on power, illuminance, and reflection direction to determine the plant light level; connects the time sequence labels in chronological order and associates them with the region number and time label to generate a light monitoring state chain. A spectral analysis module, based on the region number and time label in the light monitoring state chain, retrieves blue light, red light, and near-infrared data, generates trend labels, and compares the trend selection... The system generates a light absorption channel record table by associating the main absorption band corresponding to the under-illuminated and continuously decreasing light intensity with the region and time label. The envelope detection module, based on the main channel band identifier in the light absorption channel record table, calls the light energy curve under the main channel band, extracts the peak-valley sequence to obtain the envelope direction label, compares the envelope direction with the reference segment for consistency, adjusts the signal if there is a continuous offset, and maintains the signal if it is alternately stable, thus creating a remote illumination adjustment signal set. The dimming execution module, based on the signal type in the remote illumination adjustment signal set, calls the status label and main channel band identifier, integrates the illumination status and absorption channel information of each region according to continuous regional and time segments, summarizes the continuous adjustment signals in the same region, determines the adjustment direction according to the signal type, forms a dimming operation instruction list, and labels the region number and direction before transmitting it to the remote monitoring terminal to generate monitoring results.

[0014] The beneficial effects of the technical solution provided by the embodiments of the present invention include at least the following: In the present invention, a dynamic illumination state chain is established by comparing power, illuminance and reflection signals in multiple dimensions, thereby realizing the directionality and level identification of changes in illumination intensity. The main energy absorption channels are determined by combining the reflection trends of different bands, making illumination adjustment targeted and timely. Illumination offset and stable state are judged by analyzing the continuous trend of the light energy curve envelope, so that the illumination output remains balanced under changing conditions. Based on the signal correlation of time and region, zoned dimming and precise control are realized, avoiding uneven illumination or energy waste. A closed feedback structure is formed between each monitoring link, making illumination adjustment real-time and coordinated, and improving response speed and light energy utilization efficiency.

[0023] Please refer to Figure 2. The steps for obtaining the light fluctuation sequence record table are as follows: S101: Obtain the power signal of the laser illuminator output, the illuminance value of the light sensor, and the light intensity data reflected by the plant within the illumination area. Record them in the order of sampling time and establish an index. Compare the power signal, illuminance value, and reflected light intensity at adjacent time points. When the value at a later time point is higher than that at a previous time point, mark it as upward; when it is lower, mark it as downward. Record the direction label for each data point and generate a direction determination result set. In a specific illumination area A, data is obtained through the laser illuminator, light sensor, and plant reflected light intensity sensor at continuous sampling time points (e.g., T1=10:00:01 to T6=10:00:06). The data includes the output power of the laser illuminator. (W) Illuminance value measured by the light sensor (lx) and plant reflected light intensity data The raw data (mW / sr) were collected and recorded in chronological order and associated with area A, as shown in Table 1: Table 1: Raw Monitoring Data of Area A As shown in Table 1, this table displays the raw monitoring data of area A from time T1 to T6, with the data at time T1 as an example. W, lx, Using mW / sr as the initial reference, the power, illuminance, and reflected light intensity at adjacent time points are compared item by item to determine the direction of change. For example, comparing time T2 with time T1: W is higher than W (power up) lx is higher than lx (illuminance up) mW / sr is higher than mW / sr (reflection uplink), comparison between time T3 and time T2: W is lower than W (power downlink) lx is lower than lx (illuminance downscaling) mW / sr is higher than mW / sr (reflection up), this process continues until time T6, generating direction labels for each parameter. For example, at time T4, the direction labels are power up, illuminance up, and reflection up; at time T5, the direction labels are power up, illuminance up, and reflection up; and at time T6, the direction labels are power down, illuminance down, and reflection up. The direction labels are associated with the corresponding time index and region number to form a direction determination result set.

[0024] S102: Based on the direction determination result set, calculate the variation amplitude of power signal, illuminance value, and reflected light intensity within the same sampling window, sort them according to amplitude magnitude, and label them as first level, second level, or third level, record the corresponding level labels, and organize them with time index and area number to generate a level sorting result table; based on the direction determination result set, calculate the variation amplitude of power, illuminance, and reflected light intensity within each sampling window from T2 to T6. That is, the absolute value of the difference between data at adjacent time points, for example, the power change at time T2. W; Illuminance variation range lx; the range of change in reflected light intensity. mW / sr; Similarly; Time T3: W, lx, mW / sr; T4 time: W, lx, mW / sr; T5 time: W, lx, mW / sr; T6 time: W, lx, mW / sr; The calculated change range is labeled with a level according to the preset level classification threshold (as shown in Table 2); Table 2: Level Classification Threshold Table for Change Range As shown in Table 2, this table provides specific thresholds for classifying the levels of power, illuminance, and reflected light intensity variations. The levels are divided into three categories: Level 1 (high amplitude), Level 2 (medium amplitude), and Level 3 (low amplitude). The threshold values ​​are... and Based on the steady-state fluctuation range and supplementary lighting response sensitivity, the following was determined: 1 hour of steady-state data was collected from area A, with a fluctuation range of [missing information]. W (power), lx (illuminance) mW / sr (reflection), set accordingly (The boundary between the third and second levels) are respectively W, lx, mW / sr, determined through supplementary lighting response experiments. (The boundary between the first and second levels) are respectively W, lx, mW / sr, amplitude It is the third level. It is the second level. As the first level, time T2 is labeled as (Power: Second, Illuminance: Second, Reflection: Second), time T3 as (Power: Second, Illuminance: Third, Reflection: Second), time T4 as (Power: First, Illuminance: First, Reflection: Second), time T5 as (Power: First, Illuminance: First, Reflection: Second), and time T6 as (Power: First, Illuminance: First, Reflection: First). These level labels, together with the time index and area number, generate a level sorting result table.

[0025] S103: Based on the direction determination result set and the grade sorting result table, compare the direction labels and grade labels of power, illuminance, and reflected light intensity at the same time point to form a comprehensive change trajectory for each sampling point. Archive the trajectory by region number and time label to generate a light fluctuation sequence record table. Combine the direction determination result set and the grade sorting result table to combine the direction labels and grade labels of power, illuminance, and reflected light intensity at each sampling time point to form a comprehensive change trajectory. Specifically, retrieve the direction label (power: up, illuminance: up, reflection: up) and grade label for region A at time T2. The labels (Power: Level 2, Illuminance: Level 2, Reflectance: Level 2) are combined to form the comprehensive trajectory at time T2: (Power: Upward, Level 2; Illuminance: Upward, Level 2; Reflectance: Upward, Level 2). The direction labels (Power: Downward, Illuminance: Downward, Reflectance: Upward) and level labels (Power: Level 2, Illuminance: Level 3, Reflectance: Level 2) for region A at time T3 are retrieved, and combined to form the comprehensive trajectory at time T3: (Power: Downward, Level 2; Illuminance: Downward, Level 3; Reflectance: Upward, Level 2). The trajectory at time T4 is then retrieved. The directional labels (power: up, illuminance: up, reflectance: up) and level labels (power: level 1, illuminance: level 1, reflectance: level 2) of region A are combined to form the comprehensive change trajectory at time T4: (power: up, level 1; illuminance: up, level 1; reflectance: up, level 2). Then, the directional labels (power: up, illuminance: up, reflectance: up) and level labels (power: level 1, illuminance: level 1, reflectance: level 2) of region A at time T5 are retrieved and combined to form the comprehensive change trajectory at time T5: (power: up, level 1, illuminance: level 1, reflectance: level 2). Level; Illuminance: Upward, Level 1; Reflection: Upward, Level 2), retrieve the direction label (Power: Downward, Illuminance: Downward, Reflection: Upward) and level label (Power: Level 1, Illuminance: Level 1, Reflection: Level 1) of region A at time T6, and combine them to form the comprehensive change trajectory at time T6: (Power: Downward, Level 1; Illuminance: Downward, Level 1; Reflection: Upward, Level 1). Archive and store the comprehensive change trajectories of each sampling point formed from time T2 to T6 according to the region number A and the time label T2 to T6 to generate an illumination fluctuation sequence record table.

[0026] Please refer to Figure 3. The steps for obtaining the illumination monitoring state chain are as follows: S201: Obtain the direction labels and level labels of power direction, illuminance direction and reflection direction in the illumination fluctuation sequence record table, compare the data at each time point, and when the power direction and illuminance direction are both upward and the reflection direction is upward, check the level labels of power and illuminance. When both are at the first level, mark it as an over-illumination state and write the corresponding time point into the state field to generate an over-illumination judgment result set; Obtain the comprehensive change trajectory of each time point (T2 to T6) from the illumination fluctuation sequence record table and determine whether the over-illumination conditions are met. The over-illumination conditions include: (1) the power, illuminance and reflection directions are all upward; (2) the power and illuminance level labels are both at the first level. Determine the trajectory at time T2: (power: upward, second level; illuminance: upward, second level; reflection: upward, second level), which meets condition 1 but does not meet condition 2. =Second level, =Second level), therefore T2 is not marked as over-illuminated. Determine the trajectory at time T3: (Power: Downward, Second Level; Illuminance: Downward, Third Level; Reflection: Upward, Second Level). It does not satisfy condition 1 (power and illuminance directions are downward), therefore T3 is not marked as over-illuminated. Determine the trajectory at time T4: (Power: Upward, First Level; Illuminance: Upward, First Level; Reflection: Upward, Second Level). It satisfies condition 1 (both are upward) and also satisfies condition 2 ( =First level, =First level), so T4 is marked as over-illuminated. Continue to judge the trajectory at time T5: (Power: Upward, First level; Illuminance: Upward, First level; Reflection: Upward, Second level), which satisfies conditions 1 and 2, so T5 is marked as over-illuminated. Judge the trajectory at time T6: (Power: Downward, First level; Illuminance: Downward, First level; Reflection: Upward, First level), which does not satisfy condition 1 (power and illuminance directions are downward), so T6 is not marked as over-illuminated. Summarize all time points marked as over-illuminated (T4, T5) to generate an over-illumination judgment result set.

[0027] S202: Based on the over-illumination judgment result set, continue to compare the power direction, illuminance direction and reflection direction. When the power direction and illuminance direction are both downward and the reflection direction is upward, extract the level label of the reflection direction. When the level is the first level, mark it as under-illumination state, and write the results into the status field in time order to generate the under-illumination judgment result set. Based on the over-illumination judgment result set (T4, T5), compare the under-illumination conditions of the time points (T2, T3, T6) that are not marked as over-illumination in the light fluctuation sequence record table. The under-illumination conditions include: (1) power The direction is downward, the illuminance direction is downward and the reflection direction is upward; (2) the level label of the reflection direction is the first level, judge the trajectory at time T2: (power: upward, second level; illuminance: upward, second level; reflection: upward, second level), which does not meet condition 1 (all directions are upward), so T2 is not marked as underilluminated, judge the trajectory at time T3: (power: downward, second level; illuminance: downward, third level; reflection: upward, second level), which meets condition 1 (power downward, illuminance downward, reflection upward), but the reflection level =Second level, does not meet condition 2, therefore T3 is not marked as under-illuminated. Determine the trajectory at time T6: (Power: Downward, First level; Illuminance: Downward, First level; Reflection: Upward, First level), which satisfies condition 1 (Power Downward, Illuminance Downward, Reflection Upward), and the reflection level... =First level, condition 2 is met, so T6 is marked as under-illuminated. All time points marked as under-illuminated (T6) are summarized to generate the under-illuminated judgment result set.

[0028] S203: Using the over-illumination judgment result set and the under-illumination judgment result set, filter the time points where the power direction, illuminance direction and reflection direction are consistent. When the corresponding level labels are all level 2 or level 3, mark them as stable illumination state. Connect the three types of states in chronological order and archive them with the area number and time label to generate the illumination monitoring state chain; Using the over-illumination judgment result set (T4, T5) and the under-illumination judgment result set (T6), filter the time points (T2, T3) that have not yet been marked in the illumination fluctuation sequence record table and determine whether they meet the stable illumination conditions. The stable illumination conditions include: (1) the power, illuminance and reflection direction are consistent; (2) the corresponding level labels are all level 2 or level 3. Determine the trajectory at time T2: (Power: Upward, Level 2) The following conditions are met: (Level 1; Illuminance: Upward, Level 2; Reflection: Upward, Level 2). Therefore, T2 is marked as a stable illumination state. The trajectory at time T3 is determined as follows: (Power: Downward, Level 2; Illuminance: Downward, Level 3; Reflection: Upward, Level 2). This does not meet condition 1 (Power downward, Illuminance downward, Reflection upward). Therefore, T3 is not marked as stable illumination. After completing the state marking for all time points, the three states—stable illumination (T2), over-illuminated (T4, T5), and under-illuminated (T6)—are connected in chronological order and associated with the A-area number to form the state sequence of A-area [T2: Stable Illumination, T4: Over-illuminated, T5: Over-illuminated, T6: Under-illuminated], generating the illumination monitoring state chain.

[0029] Please refer to Figure 4. The steps for obtaining the light absorption channel record table are as follows: S301: Obtain the area number and time tag in the light monitoring status chain, locate the monitoring segment according to the time tag, call the blue light, red light and near-infrared reflected light intensity records in the same area and time period, arrange the reflected light intensity values ​​of each band in chronological order, calculate the difference between adjacent sampling points, mark the difference as upward when the difference is positive, mark the difference as downward when the difference is negative, and record the direction tag to generate the band direction sequence; obtain the light monitoring status. The A region number and time tag sequence in the chain [T2: stable illumination, T4: over-illuminated, T5: over-illuminated, T6: under-illuminated] are used. The time T6, when the under-illuminated state occurs, and its preceding time period (T4, T5) are selected as the monitoring segment (T4-T6). The reflected light intensity records of blue light (450nm), red light (660nm), and near-infrared light (730nm) already archived in the A region within this monitoring segment (T4, T5, T6) are retrieved, as shown in Table 3: Table 3: Multi-band reflected light intensity table of A region Table 3 lists the reflected light intensity data of blue, red, and near-infrared bands collected in region A from time T3 to T6. The reflected light intensity values ​​of each band at times T4, T5, and T6 are arranged in chronological order. The differences between adjacent sampling points are calculated, and the directions are marked. For example, at time T5 (compared to T4): blue light mW / sr (upward), red light mW / sr (uplink), near-infrared mW / sr (downlink), therefore the direction labels at time T5 are (blue light: uplink, red light: uplink, near-infrared: downlink), and similarly at time T6 (compared to T5): blue light mW / sr (downlink), red light mW / sr (uplink), near-infrared mW / sr (downward), so the direction label at time T6 is (blue light: downward, red light: upward, near-infrared: downward). Record the direction labels of each band at times T5 and T6 to generate a band direction sequence.

[0030] S302: Based on the band direction sequence, organize the direction labels of blue light, red light, and near-infrared light in chronological order, determine the continuity of direction changes within continuous sampling segments, mark a unidirectional trend when the direction remains the same, and mark a fluctuating trend when the direction changes alternately. Record the trend labels of the three bands by time index to generate a band trend result set; based on the band direction sequence (T5 time: blue light - up, red light - up, near-infrared - down; T6 time: blue light - down, red light - up, near-infrared - down), and the direction at T4 time (compared to T3) (blue light: down, red light: up, near-infrared: down), organize the direction labels of blue light, red light, and near-infrared light in chronological order T4, T5, T6, to obtain the blue light direction sequence as [T4: down, T5: up, T6: down], and the red light direction sequence as [ [T4: Upward, T5: Upward, T6: Upward], and the near-infrared directional sequence is [T4: Downward, T5: Downward, T6: Downward]. The continuation of directional changes within the continuous sampling segment T4-T6 is determined to identify the trend label for each band. Specifically, the direction of the blue light sequence [Downward, Upward, Downward] changes in both T4-T5 and T5-T6, thus it is marked as a fluctuating trend. The direction of the red light sequence [Upward, Upward, Upward] remains the same (upward) within the T4-T6 segment, thus it is marked as a unidirectional trend. The direction of the near-infrared sequence [Downward, Downward, Downward] remains the same (downward) within the T4-T6 segment, thus it is marked as a unidirectional trend. The trend labels for the three bands—blue light (fluctuating trend), red light (unidirectional trend), and near-infrared (unidirectional trend)—are recorded according to the time index (T4-T6 segment) to generate a band trend result set.

[0031] S303: Call the band trend result set, compare the trend labels of blue light, red light, and near-infrared light within the same time period, filter the bands that correspond to the under-illumination state and show a continuous downward trend, extract their corresponding area numbers and match them with time labels, establish the association record between the bands and the monitoring sections, and generate a light absorption channel record table; call the band trend result set (T4-T6 section: blue light - fluctuating trend, red light - unidirectional trend, near-infrared - unidirectional trend), compare the trend labels of each band within the same time period (T4-T6), and filter the bands that correspond to the under-illumination state (T6 time) in the light monitoring state chain and show a continuous downward trend, where the red light trend is "unidirectional trend", and the direction sequence is [ The trend [upward, upward, upward] is a continuous upward trend, which does not meet the condition of "continuous downward trend", so it is excluded. The blue light trend is a "fluctuating trend" with a direction sequence of [downward, upward, downward], which does not meet the condition of "continuous downward trend", so it is excluded. The near-infrared trend is a "unidirectional trend" with a direction sequence of [downward, downward, downward], which is a continuous downward trend and meets the condition of "continuous downward trend". Therefore, the near-infrared band is selected as the main absorption channel. The corresponding A area number is extracted and matched with the time label (T4-T6) to establish the association record between the near-infrared band and the T4-T6 monitoring section of A area, forming (A area, T4-T6, near-infrared channel), and generating a light absorption channel record table.

[0032] Please refer to Figure 5. The steps for obtaining the remote illumination adjustment signal set are as follows: S401: Obtain the main channel band identifier in the light absorption channel record table, retrieve the light energy change curve of each region under the corresponding band, align each sampling point according to the time label, extract the peak and valley positions of light energy in adjacent sampling segments, record the order of peak appearance and mark the direction of the envelope, continuously record in the same region to form an envelope change record, and generate an envelope direction sequence; Obtain the main channel band identifier in the light absorption channel record table, that is, the main channel of region A in the T4-T6 segment is the near-infrared (NIR) band, retrieve the light energy change curve of region A under the near-infrared band ( (Reflected light intensity data), aligning each sampling point according to time labels T1 to T6 (T1: 2.1, T2: 2.0, T3: 2.0, T4: 1.9, T5: 1.9, T6: 1.8, where T3-T6 data comes from Table 3, and T1-T2 is hypothetical historical data), extracting the peak and valley positions of light energy within the continuous sampling segment T1-T6. Specifically, in the T1-T3 segment: T1 (2.1) is the local peak position P1, and T2 (2.0) is the local peak position P1. The valley position is V1, and T3 (2.0) remains at V1. The peak-valley sequence is P1->V1, and the envelope direction is "decreasing" (peak->valley). In the T4-T6 segment: T4 (1.9) is the local valley position V2 after T3, T5 (1.9) remains at V2, and T6 (1.8) is the new local valley position V3. The peak-valley sequence is V2->V3, and the envelope direction is "decreasing" (valley->valley). The "decreasing" direction of the T1-T3 period and the T4-T6 period are continuously recorded in the A region to form an envelope change record and generate an envelope direction sequence [T1-T3: decreasing, T4-T6: decreasing].

[0033] S402: Based on the envelope trend sequence, determine the envelope reference curve for the starting segment of the current monitoring period. Compare the peak-valley arrangement order of subsequent sampling segments with the envelope reference, calculate the displacement difference between the upper and lower envelopes. When the peak-valley order is consistent and the displacement direction is the same, it is recorded as a consistent state. When the order is inconsistent or the displacement direction is opposite, it is recorded as an offset state. Generate the envelope consistency comparison result. Based on the envelope trend sequence [T1-T3: decreasing, T4-T6: decreasing], determine the envelope of the starting segment (T1-T3) of the current monitoring period as the reference curve. Its envelope trend is "decreasing", and the peak-valley arrangement order is P1(2.1)->V1(2.0). Refer to the upper envelope. [2.1], lower envelope For [2.0], the peak-valley arrangement order (V2(1.9)->V3(1.8)) of the subsequent sampling segment (T4-T6) is compared with the envelope reference (P1->V1). It is found that the peak-valley order (valley->valley) of T4-T6 is inconsistent with the reference (peak->valley), and the lower envelope values ​​(1.9,1.8) of T4-T6 are all lower than the reference lower envelope value (2.0). The displacement direction is downward. According to the judgment rule, when the peak-valley order is inconsistent, it is recorded as an offset state. Here, the peak-valley order of the T4-T6 segment is inconsistent, so the T4-T6 segment is recorded as an offset state, and the envelope consistency comparison result [T4-T6: offset state] is generated.

[0034] S403: Call the envelope consistency comparison results to determine the envelope orientation labels of the continuous sampling segments. When the envelope orientation remains in the same direction within the continuous segment and is inconsistent with the reference, it is recorded as an offset signal. When the envelope orientation alternates within the continuous segment and is consistent with the reference, it is recorded as a stable signal. Organize and number the signals of each region in chronological order to generate a remote illumination adjustment signal set. Call the envelope consistency comparison results (T4-T6: offset state) and combine them with the envelope orientation sequence (reference T1-T3: descent; segment T4-T6: descent) to determine the envelope of the continuous sampling segments. The direction label is used for judgment. The direction label of the judgment segment T4-T6 is "descending". The direction label of the reference (T1-T3) is also "descending". The two are in the same direction and the comparison result is "offset state" (i.e. inconsistent with the reference). The judgment condition "the direction of the envelope is in the same direction in the continuous segment and is inconsistent with the reference" is met. Therefore, the T4-T6 segment is recorded as an offset signal. In this embodiment, T4-T6 is determined to be an offset signal. The "offset signal" of region A is sorted and numbered in chronological order (T4-T6) to generate a remote illumination adjustment signal set.

[0035] Please refer to Figure 6. The steps for obtaining remote monitoring results are as follows: S501: Obtain the signal type in the remote illumination adjustment signal set, call the status label in the illumination monitoring status chain and the main channel band identifier in the light absorption channel record table, organize them according to the area number and time label, match the signal type, illumination status and main channel band in the same area, and merge the results according to the continuous time segment to generate an integrated regional illumination record; Obtain the signal type in the remote illumination adjustment signal set, that is, the signal type of area A in the T4-T6 segment is "offset signal", call the status label [T2: stable illumination, T4: over-illumination, T5: over-illumination, T6: under-illumination] in the illumination monitoring status chain and the main channel in the light absorption channel record table. The band identifier (Area A, T4-T6, near-infrared channel) is organized and matched according to the area number and time label (T4, T5, T6). Specifically, at time T4: signal type = offset signal, illumination status = over-illuminated, main channel = near-infrared; at time T5: signal type = offset signal, illumination status = over-illuminated, main channel = near-infrared; at time T6: signal type = offset signal, illumination status = under-illuminated, main channel = near-infrared. The signal type, illumination status, and main channel band in area A are merged according to the continuous time segment (T4-T6) to form (Area A, T4-T6, offset signal, [T4: over-illuminated, T5: over-illuminated, T6: under-illuminated], near-infrared channel), generating a regional illumination integration record.

[0036] S502: Based on the integrated regional illumination record, filter the adjustment signals that appear consecutively in the same region under the same main channel, compare the directional changes of adjacent signal types, record the signal as "maintain" when the consecutive signals have the same direction, and record the signal as "adjust" when the directions are opposite, classify them according to the upward and downward adjustment directions, and generate the regional adjustment direction distribution; based on the integrated regional illumination record (Area A, T4-T6, offset signal, [T4: over-illuminated, T5: over-illuminated, T6: under-illuminated], near-infrared channel), filter the adjustment signals (offset signals) that appear consecutively in Area A under the same main channel (near-infrared channel). The T4-T6 segment is an offset signal, which meets the condition of consecutive occurrence. According to the merged illumination state [T4: over-illuminated], [T5: Over-illuminated, T6: Under-illuminated] Determine the adjustment direction, where the state at time T4 is "over-illuminated" and the adjustment direction is "down" (reducing illumination), the state at time T5 is "over-illuminated" and the adjustment direction is "down", and the state at time T6 is "under-illuminated" and the adjustment direction is "up" (increasing illumination). Compare the direction changes of adjacent signals. If the directions of T4 (down) and T5 (down) are the same, record it as "maintain" (maintain down adjustment). If the directions of T5 (down) and T6 (up) are opposite, record it as "adjust" (adjust from down to up). Classify according to the direction of up and down adjustment to generate the adjustment direction distribution of region A in the T4-T6 segment [T4: down, T5: down, T6: up].

[0037] S503: Invoke the regional adjustment direction distribution, summarize the adjustment direction of each region and the continuous time segment to form the dimming operation command for the lighting area, label the adjustment direction and command information according to the region number, and transmit the result to the remote monitoring terminal to generate the remote monitoring result; Invoke the adjustment direction distribution of region A [T4: down, T5: down, T6: up], summarize the adjustment direction of region A and the continuous time segment, summarize the time period T4-T5 (corresponding to T4: over-illumination, T5: over-illumination) as "down", and summarize the time period T6 (corresponding to T6: under-illumination) as "up", forming the dimming operation command for the lighting area. Command 1: Region A, time period T4-T5, execute down operation, the specific command information is to reduce the total power of the laser illuminator. (Based on T4 and T5 over-illumination status), Instruction 2: In area A, during time period T6, execute an upward adjustment operation. The specific instruction is to increase the power of the near-infrared channel (based on the main channel) of the laser illuminator. (Based on T6 under-illuminated status), the result lists of Command 1 and Command 2 are transmitted to the remote monitoring terminal. The remote monitoring terminal receives and executes [Command 1: Area A, T4-T5, reduce total power]. [Command 2: Area A, T6, Near-infrared power increased] ], generate remote monitoring results.

The main absorption band, corresponding to the under-illuminated and continuously decreasing light, is associated with the region and time label to generate a light absorption channel record table. The envelope detection module, based on the main channel band identifier in the light absorption channel record table, calls the light energy curve under the main channel band, extracts the peak-valley sequence to obtain the envelope direction label, compares the envelope direction with the reference segment for consistency, adjusts the signal if there is a continuous offset, and maintains the signal if there is an alternating stability, and remotely adjusts the signal set.
