Technical Field

[0001] The present application relates to the field of lighting control technology, and in particular to an intelligent lighting control method, system, electronic device and storage medium. Background Art

[0002] With the rapid development of science and technology and the continuous improvement of people's quality of life, the requirements for lighting in modern working environments are becoming higher and higher, especially in offices, schools or other places that require long periods of mental concentration. Unsuitable lighting conditions may cause eye fatigue. Therefore, how to create a comfortable visual environment for users of electronic devices and reduce visual fatigue through intelligent control of lighting fixtures has become an urgent problem to be solved.

[0003] At present, the existing intelligent lighting control method uses a pre-set lighting brightness to illuminate the personnel in the work area by controlling the capacitance of the corresponding branch of each lamp in the work area. However, in actual applications, due to the dynamic changes in ambient light, the personnel in the work area will have different degrees of visual fatigue and there are many branch capacitances. It is often difficult to adapt to the changes in ambient light and the visual fatigue of personnel by only using the pre-set lighting brightness to adjust the capacitance of different lamps. When adjusting the capacitance, a large number of adjustments need to be repeated, which makes it easier to make errors in capacitance adjustment, resulting in low accuracy of intelligent lighting control. Summary of the invention

[0006] By adopting the above technical solution, the visual fatigue index and ambient light information of the personnel in the work area are obtained, and the system can intelligently determine the optimal target lighting brightness of the work area. The visual fatigue index is calculated based on the employee's screen usage time and blinking times, and then compared with the ambient brightness to determine the difference. If the fatigue index exceeds the threshold, the optimal target lighting brightness is calculated using the index and the brightness difference. Then, the target capacitance parameter of the lamp is reversely determined according to the target brightness, and the lamp output is controlled by the parameter to achieve intelligent optimization of the lighting of the work area. Based on the detection and evaluation of the human visual state and ambient light, this technical solution can accurately determine the optimal lighting conditions of the work area. By considering multi-dimensional data, the lighting fixtures are dynamically adjusted to create a suitable lighting atmosphere for the personnel in the work area. By setting a unified capacitor in the main circuit instead of setting a single capacitor for each lighting fixture, the situation where the capacitor adjustment needs to be repeatedly adjusted for each lamp is avoided, which can reduce the risk of capacitor adjustment errors. By setting a unified capacitor in the main circuit for dynamic adjustment of lighting fixtures, the accuracy of intelligent lighting control is improved.

The visual fatigue index is calculated based on the screen usage time and the number of blinks of the employees, and then compared with the ambient brightness to determine the difference. If the fatigue index exceeds the threshold, the optimal target lighting brightness is calculated using the index and the brightness difference. Then, the target capacitance parameter of the lamp is reversely determined according to the target brightness, and the lamp output is controlled by the parameter to achieve intelligent optimization of the lighting of the working area. Based on the detection and evaluation of the human visual state and ambient lighting, the technical solution can accurately judge the optimal lighting conditions of the working area. By considering multi-dimensional data, the lighting fixtures are dynamically adjusted to create a suitable lighting atmosphere for the personnel in the working area. By setting a unified capacitor in the main circuit instead of setting a single capacitor for each lighting fixture, the situation where the capacitor needs to be repeatedly adjusted for each lamp is avoided, which can reduce the risk of capacitor adjustment errors.

[0016] The present application embodiment provides an intelligent lighting control method. In one embodiment, please refer to Figure 1 , Figure 1 : is a flow chart of the intelligent lighting control method provided by the embodiment of the present application. The method can be implemented by a computer program, which can be integrated into an application or run as an independent tool application. The method can also be implemented by a single-chip microcomputer or run on an intelligent lighting control system based on the von Neumann system. Specifically, the method can include the following steps: Step 101: Obtaining personnel information in the work area and ambient lighting information of the environment in which the work area is located.

[0017] Among them, personnel information refers to a series of data parameters related to the visual fatigue status of people in the working area. In the embodiment of the present application, it can be understood as including parameters such as the number of times a person blinks, screen usage time, etc. These parameters can reflect the degree of visual fatigue of the person.

[0018] Ambient lighting information refers to data related to the lighting environment of the working area, and in the embodiment of the present application, it can be understood as parameters such as ambient brightness and light intensity in the working area. These parameters can reflect the ambient lighting conditions of the working area.

[0019] Specifically, through the cameras and sensors installed in the work area, the number of times the staff blinks, working hours and other information are collected in real time, and the image recognition algorithm is used to calculate the length of time the user stares at the display screen for a long time to monitor the user's visual fatigue. The data of the ambient light sensor installed in the work area is obtained to detect the real-time ambient light intensity and brightness information. By obtaining personnel information and ambient light information, the system can calculate the visual fatigue index of the personnel in the work area, and combine it with the ambient light conditions to determine whether the current ambient light is sufficient to meet the work needs. If it is insufficient, the lighting brightness needs to be increased; if it is too strong, the lighting brightness needs to be reduced. In this way, the lighting needs of the work area can be dynamically calculated based on these key information, thereby guiding the subsequent intelligent lighting control and providing personnel with a suitable working lighting environment.

[0020] Step 102: Based on the screen usage time and blink times in the personnel information, determine the visual fatigue index of the employees in the work area, and determine the brightness difference according to the standard lighting brightness and the ambient brightness in the ambient lighting information.

[0021] Among them, screen usage time refers to the length of time that the staff stares at the display screen over a period of time. In the embodiment of the present application, it can be understood as the time parameter of personnel using the display device calculated by statistics using the camera and image recognition algorithm.

[0022] The number of blinks refers to the number of times a staff member blinks within a certain period of time. In the embodiment of the present application, it can be understood as a parameter of the number of times a person blinks within a given time period that is statistically calculated by a camera and an image recognition algorithm.

[0023] The visual fatigue index refers to a comprehensive parameter used to evaluate the degree of visual fatigue of staff members. In the embodiment of the present application, it can be understood as an index value calculated based on the screen usage time and the number of blinks.

[0024] Standard lighting brightness refers to the recommended lighting brightness level under normal working conditions, which can be understood in the embodiment of the present application as the ideal lighting brightness parameters of the working area preset in advance based on the visual needs of personnel.

[0025] Ambient brightness refers to the current ambient light illumination brightness of the working area, which can be understood in the embodiment of the present application as the real-time brightness value in the working area collected by the ambient light sensor.

[0026] Specifically, based on the screen usage time data and blinking times data of employees, a preset calculation formula is applied to comprehensively determine a visual fatigue index that represents the degree of visual fatigue. During the calculation process, longer screen usage time and fewer blinking times will lead to a higher visual fatigue index. After calculating the visual fatigue index, the system reads the ambient brightness value detected by the ambient light sensor, compares it with the preset standard working area lighting brightness, and calculates the difference between the current ambient brightness and the standard brightness, that is, the brightness difference. The purpose of this is to evaluate the current visual fatigue status of employees in the working area and whether the ambient lighting meets the standard working requirements. If the employee's visual fatigue index is too high, it means that the visual fatigue is serious, and the ambient brightness is lower than the standard brightness. At this time, the system needs to increase the lighting brightness output accordingly; on the contrary, if the employee's visual fatigue level is acceptable and the ambient brightness is sufficient, the current lighting brightness is maintained unchanged. By determining the visual fatigue index and calculating the brightness difference, it can be accurately determined whether the lighting brightness output of the working area needs to be adjusted.

[0027] Based on the above embodiment, as an optional embodiment, in step 102: determining the visual fatigue index of employees in the work area based on the screen usage time and the number of blinks in the personnel information, this step may also include the following steps: Step 201: Obtain the working hours of employees in the work area; determine the blinking frequency of the employees based on the working hours and the number of blinks.

[0028] Among them, working hours refer to the length of time an employee works continuously within a period of time. In the embodiment of the present application, it can be understood as the actual working time parameters of the employee in the work area statistically calculated by the camera and image recognition algorithm.

[0029] Blinking frequency refers to the number of times an employee blinks during a certain working period. In the embodiment of the present application, it can be understood as the average number of blinks of an employee during a given working period, which is calculated by using a camera and an image recognition algorithm.

[0030] Specifically, the actual working hours of employees in the work area are calculated through image recognition algorithms. Then, the system reads the total number of blinks of the employee during the corresponding working hours obtained in the early stage. Based on these two data, the average blinking frequency during this period can be calculated, that is, the average number of blinks per hour. The purpose of this is to analyze the visual fatigue level of employees from the two dimensions of blinking and working hours. It is not accurate enough to only look at the absolute number of blinks. The blinking frequency needs to be calculated in combination with the working hours, because the normal number of blinks will vary under different working hours. The lower the employee's blinking frequency, the more severe the visual fatigue. By determining the blinking frequency, the visual fatigue level of employees can be more comprehensively evaluated, and the visual fatigue index can be accurately calculated based on this. This can adjust the lighting output according to the actual visual fatigue status of the employees to achieve the effect of reducing visual fatigue.

[0031] Step 202: Divide the screen usage time by the preset standard usage time to obtain a time ratio, and divide the employee's blinking frequency by the preset standard blinking frequency to obtain a frequency ratio.

[0032] The preset standard usage time refers to the standard value of the duration of continuous use of the display screen recommended under normal working conditions, and can be understood as an ideal screen usage time parameter pre-set according to the visual health needs of personnel in the present application embodiment. The preset standard usage time is used as a benchmark value for calculating the ratio of the actual screen usage time of employees to the standard time.

[0033] The preset standard blink frequency refers to the standard value of the average blink frequency recommended under normal working conditions, and can be understood as an ideal blink frequency parameter preset according to the visual health needs of personnel in the present application embodiment. The preset standard blink frequency is used as a reference value for calculating the ratio of the employee's actual blink frequency to the standard frequency.

[0034] The duration ratio refers to the ratio of an employee's actual screen usage duration to a preset standard usage duration. In the embodiment of the present application, it can be understood as the ratio result obtained by dividing the employee's actual usage duration by the standard duration.

[0035] The frequency ratio refers to the ratio of the actual average blinking frequency of an employee to the preset standard blinking frequency. In the embodiment of the present application, it can be understood as the ratio result obtained by dividing the actual blinking frequency of the employee by the standard blinking frequency.

[0036] Specifically, the actual screen usage time data of the employee obtained by statistics is divided by the preset standard normal screen usage time value, and the ratio of the employee's screen usage time to the standard time, that is, the time ratio, can be calculated. The actual average blinking frequency data calculated by the employee is divided by the preset standard normal blinking frequency value, and the ratio of the employee's blinking frequency to the standard frequency, that is, the frequency ratio, can be calculated. The purpose of this is to more clearly and intuitively reflect the deviation between the employee's visual fatigue level and the standard level through ratio calculation. The lower the duration ratio and frequency ratio, the more the employee's visual state deviates from the normal standard, and the greater the risk of visual fatigue. The ratio can quickly and accurately indicate the state of visual fatigue. After obtaining the duration ratio and frequency ratio, the employee's visual fatigue level can be accurately assessed based on this, and the lighting output can be adjusted accordingly to improve the control efficiency of lighting fixtures.

[0037] Step 203: sum the duration ratio and the frequency ratio to obtain the visual fatigue index of the employees in the work area.

[0038] Specifically, the calculated ratio of the employee's screen usage time in the work area to the standard time (the time ratio), and the ratio of the employee's blinking frequency to the standard frequency (the frequency ratio), are added together to obtain a visual fatigue index that comprehensively reflects the employee's visual fatigue level. The purpose of this is to obtain an overall, unified index to evaluate visual fatigue. The separate time ratio and frequency ratio can only reflect one aspect of visual fatigue, and combining them and summing them can obtain a more comprehensive index.

[0039] Based on the above embodiment, as an optional embodiment, in step 102: determining the brightness difference according to the standard lighting brightness and the ambient brightness in the ambient lighting information, this step may also include the following steps: Step 204: Compare the standard lighting brightness with the ambient brightness; if the standard lighting brightness is greater than the ambient brightness, subtract the ambient brightness from the standard lighting brightness to obtain a brightness difference.

[0040] The brightness difference refers to the numerical difference between the current ambient brightness and the standard brightness, which can be understood as the difference between the actual ambient brightness and the preset standard brightness in the embodiment of the present application.

[0041] Specifically, the preset standard lighting brightness value of the working area is obtained, and at the same time, the current actual ambient brightness value in the area detected in real time by the ambient light sensor is called. The system will compare these two brightness values ​​to determine whether the standard brightness is higher than the current actual brightness. If the judgment result is that the standard brightness is greater, the system will subtract the current actual ambient brightness value from the standard brightness value, and the difference obtained is the specific difference value of the current ambient brightness below the standard brightness, which is the brightness difference. This is done to calculate the specific difference between the current ambient brightness and the ideal standard brightness. Only by clarifying the difference between the two can the system determine the specific magnitude of the ambient brightness that needs to be increased. Obtaining the brightness difference allows the system to accurately calculate the target lighting brightness.

[0042] Step 205: If the standard lighting brightness is less than or equal to the current ambient brightness, the brightness difference is set to zero.

[0043] Specifically, after comparing the standard brightness and the current ambient brightness, if it is found that the standard brightness is not greater than the current brightness, that is, the standard brightness is less than or equal to the current brightness, then the system will directly set the brightness difference value to zero. This is because when the standard brightness does not exceed the current ambient brightness, it means that the current ambient brightness has met the standard requirements and there is no need to adjust the brightness, so the brightness difference should be set to zero, indicating that there is no gap between the current environment and the standard brightness, and no dimming operation is required. Setting the brightness difference to zero can avoid the system from making the wrong operation of increasing the lighting brightness when dimming is not required. Correctly setting the brightness difference to zero can enable the system to determine that dimming is not required, thereby avoiding unnecessary dimming control.

[0044] Step 103: If the visual fatigue index is greater than or equal to the fatigue index threshold, the target lighting brightness of the working area is calculated by combining the visual fatigue index and the brightness difference.

[0045] Among them, the fatigue index threshold refers to the limit index value for judging whether the degree of visual fatigue is serious. In the embodiment of the present application, it can be understood as a threshold parameter pre-set according to the visual health standard for judging whether the visual fatigue index is too high.

[0046] The target lighting brightness refers to the ideal working area lighting brightness value that needs to be adjusted according to the visual fatigue index and the ambient brightness calculated by the system. In the embodiment of the present application, it can be understood as the target lighting output parameter that needs to be adjusted to the current environment calculated by the system according to the algorithm.

[0047] Specifically, in order to calculate a reasonable target lighting brightness for dimming when it is judged that the visual fatigue index of an employee is high, it is necessary to comprehensively consider the fatigue index and the difference between the current ambient brightness and the standard brightness when the visual fatigue index is not lower than the preset fatigue index threshold to calculate the target lighting brightness. It is judged whether the visual fatigue index of the employee is greater than or equal to the preset fatigue index threshold. If the judgment result is greater than or equal to the threshold, it means that the visual fatigue degree of the employee is relatively severe. At this time, the system will call the visual fatigue index data of the employee and the difference between the current ambient brightness and the standard brightness, that is, the brightness difference data, and calculate according to the preset calculation model to obtain the target ideal lighting brightness output value that needs to be adjusted to the current environment. The purpose of this is to determine the direction and amplitude of lighting dimming. When the visual fatigue index is high, the ambient brightness needs to be increased to help reduce visual fatigue, and the increase amplitude needs to consider the gap between the current and standard brightness. The combination of the two can obtain a scientific and reasonable target lighting brightness. After obtaining the target lighting brightness, the output of the lighting equipment can be accurately controlled to achieve the calculated target brightness, which not only achieves the effect of increasing the ambient brightness to reduce visual fatigue, but also avoids visual discomfort caused by excessive increase in illumination.

[0048] Based on the above embodiment, as an optional embodiment, in step 103: combining the visual fatigue index and the brightness difference to calculate the target lighting brightness of the working area, this step may also include the following steps: Step 301: Obtain a reference lighting brightness of a working area; determine a first adjustment coefficient corresponding to a visual fatigue index and a second adjustment coefficient corresponding to a brightness difference based on a preset adjustment coefficient mapping table.

[0049] Among them, the reference lighting brightness refers to the actual lighting brightness value of the current environment, which can be understood as the actual lighting brightness parameter of the current environment detected by the sensor in the working area in the embodiment of the present application.

[0050] The preset adjustment coefficient mapping table refers to a mapping table that stores the comparison relationship between the visual fatigue index and the brightness difference and the corresponding adjustment coefficient. In the embodiment of the present application, it can be understood as a database that stores the adjustment coefficient values ​​mapped by different visual fatigue indices and brightness differences.

[0051] The first adjustment coefficient refers to an adjustment parameter corresponding to the visual fatigue index, which can be understood as a corresponding parameter value found in a mapping table according to the size of the visual fatigue index in the embodiment of the present application.

[0052] The second adjustment coefficient refers to an adjustment parameter corresponding to the brightness difference, and in the embodiment of the present application, it can be understood as a corresponding parameter value found in a mapping table according to the brightness difference.

[0053] Specifically, in order to calculate a reasonable target lighting brightness that takes into account visual fatigue and ambient brightness, the first step is to obtain the current benchmark lighting brightness of the work area, and then determine the adjustment coefficient corresponding to the visual fatigue index and the brightness difference according to the preset adjustment coefficient mapping table. The light sensor is called to collect the actual current ambient benchmark brightness value of the work area. Then the system searches the pre-established adjustment coefficient mapping table based on the visual fatigue index of the employee and the calculated brightness difference, and obtains the first adjustment coefficient value corresponding to the visual fatigue index and the second adjustment coefficient value corresponding to the brightness difference. This is because the calculation of the target lighting brightness needs to be based on the benchmark brightness and combined with the two adjustment factors representing visual fatigue and brightness difference for parameterized adjustment. Obtaining the benchmark brightness can determine the base point, and obtaining the corresponding adjustment coefficient can quantify the adjustment amplitude. Through this process, the benchmark brightness value and the specific parameters of the two adjustment factors required for the subsequent target brightness calculation can be obtained, laying the foundation for the accurate calculation of the target lighting brightness.

[0054] Step 302: multiplying the reference lighting brightness by the first adjustment coefficient to obtain a first intermediate brightness, and multiplying the reference lighting brightness by the second adjustment coefficient to obtain a second intermediate brightness.

[0055] The first intermediate brightness refers to the product of the reference lighting brightness and the first adjustment coefficient, which can be understood as the intermediate result after the reference brightness is adjusted by the visual fatigue index in the embodiment of the present application. The first intermediate brightness is used to represent the parameterized result of the adjustment effect of the visual fatigue index factor on the reference brightness.

[0056] The second intermediate brightness refers to the product of the reference illumination brightness and the second adjustment coefficient, and can be understood as the intermediate result after the reference brightness is adjusted by the brightness difference in the present embodiment. The second intermediate brightness is used to represent the parameterized result of the adjustment effect of the brightness difference factor on the reference brightness.

[0057] Specifically, in order to quantifiably represent the influence of the two factors, the visual fatigue index and the brightness difference, on the target lighting brightness, it is necessary to multiply the obtained reference lighting brightness with the corresponding first adjustment coefficient and the second adjustment coefficient respectively to obtain an intermediate brightness result representing the two influences. The current reference lighting brightness value of the workspace that has been obtained is multiplied by the first adjustment coefficient corresponding to the visual fatigue index obtained by looking up the table to obtain the first intermediate brightness result. At the same time, the system multiplies the reference brightness with the second adjustment coefficient corresponding to the brightness difference to obtain the second intermediate brightness result. This is done to use the adjustment coefficient to perform a quantifiable adjustment operation on the reference brightness to reflect the degree to which the two factors, the visual fatigue index and the brightness difference, need to adjust the target lighting brightness. The first intermediate brightness represents the adjustment result of visual fatigue, and the second intermediate brightness represents the adjustment result of insufficient brightness. After obtaining these two intermediate brightnesses, the system can use quantified parameters to represent the adjustment effect of the two factors, providing accurate intermediate variable input for the subsequent comprehensive calculation of the target brightness.

[0058] Step 303: Add the first intermediate brightness and the second intermediate brightness to obtain an initial lighting brightness; and determine a target lighting brightness of the working area based on the initial lighting brightness and a preset brightness range.

[0059] Among them, the initial lighting brightness refers to the arithmetic sum of the first intermediate brightness and the second intermediate brightness, which can be understood as an unconstrained intermediate calculation result obtained by comprehensively adjusting the reference brightness for visual fatigue and brightness difference in the embodiment of the present application.

[0060] The preset brightness range refers to the minimum and maximum values ​​of the lighting brightness allowed in the working area. In the embodiment of the present application, it can be understood as the lower and upper limits of the reasonable lighting brightness pre-configured for the working area according to its purpose.

[0061] Specifically, the first intermediate brightness representing visual fatigue adjustment and the second intermediate brightness representing brightness difference adjustment are added to obtain the initial lighting brightness result. Then, the system determines the final target lighting brightness value of the work area through constraint calculation based on the initial brightness value and the preset allowable lighting brightness range of the work area. This is done to consider the comprehensive influence of various factors to obtain the initial brightness, and then determine the final target brightness by constraining it to a reasonable range. The initial brightness reflects the comprehensive adjustment result of all factors; combined with the preset range, the optimal target brightness can be obtained. Through this process, the optimal target lighting brightness value that comprehensively considers visual fatigue and ambient brightness can be calculated, providing a basis for subsequent precise dimming control.

[0062] Based on the above embodiment, as an optional embodiment, in step 303: determining the target lighting brightness of the working area based on the initial lighting brightness and the preset brightness range, this step may also include the following steps: Step 313: Determine whether the initial lighting brightness exceeds a preset brightness range, where the preset brightness range includes a preset brightness upper limit value and a preset brightness lower limit value; if the initial lighting brightness does not exceed the preset brightness range, the initial lighting brightness is used as the target lighting brightness.

[0063] Among them, the preset upper brightness limit value and the preset lower brightness limit value refer to the maximum value and minimum value constituting the preset brightness range, which can be understood in the embodiment of the present application as the maximum and minimum lighting brightness values ​​allowed in the area pre-configured according to the usage function of the working area.

[0064] The preset upper and lower limits of brightness are used to define the allowable range of lighting brightness in the working area, so that the calculated target lighting brightness value is within the range and meets the usage requirements of the area.

[0065] Specifically, in order to verify whether the initial lighting brightness is within the allowable range of the work area, it is necessary to determine whether the initial brightness matches the preset lighting brightness usage range of the work area, which is composed of a predetermined maximum brightness upper limit and a minimum brightness lower limit. If the initial brightness is within the range, it can be directly used as the final target brightness. Compare the calculated initial lighting brightness with the preset maximum and minimum brightness values ​​of the work area to determine whether the initial brightness is higher than the maximum value or lower than the minimum value, that is, whether it exceeds the predefined brightness usage permission range of the work area. If the initial brightness is within the range, the system will directly take the initial brightness value as the final target lighting brightness result of the work area. This is done to verify whether the initial brightness meets the actual use constraints. If it has been met, it will be directly used as the final target value to simplify the calculation process.

[0066] Step 323: If the initial lighting brightness is greater than or equal to the preset upper brightness limit, the preset upper brightness limit is used as the target lighting brightness.

[0067] Specifically, after determining that the calculated initial lighting brightness is greater than the preset maximum allowable lighting brightness value of the work area, the preset maximum brightness will be directly used as the final target lighting brightness result of the work area. This is done because the initial brightness higher than the range means that it does not meet the use requirements of the work area and must be adjusted down to the maximum allowable value to meet the lighting design. Directly taking the upper limit of the range can quickly correct unreasonable calculation results. Through this process, the optimal target lighting brightness value that takes into account both the adjustment of key factors and the use range can be obtained, providing the most reasonable parameter input for subsequent precise control of lighting.

[0068] Step 333: If the initial lighting brightness is less than the preset brightness lower limit, the preset brightness lower limit is used as the target lighting brightness.

[0069] Specifically, after determining that the calculated initial lighting brightness is less than the preset minimum allowable lighting brightness value of the work area, the preset minimum brightness will be directly used as the final target lighting brightness result of the work area. This is done because the initial brightness lower than the range means that it does not meet the use requirements of the work area and must be adjusted to the minimum allowable value to comply with the lighting design. Directly taking the lower limit of the range can quickly correct unreasonable calculation results. Through the above processing, the system can obtain the optimal target lighting brightness value that takes into account both the adjustment of key factors and the use range, providing the most reasonable parameter basis for subsequent precise control of lighting.

[0070] Step 104: Determine target capacitance parameters of the lighting fixtures in the working area according to the target lighting brightness, and adjust the capacitance of the main circuit based on the target capacitance parameters to control the lighting fixtures for lighting.

[0071] The target capacitance parameter refers to the capacitance value of the lamp used to achieve the target lighting brightness, which can be understood as the capacitance value required for the lamp determined according to the calculated target brightness in the embodiment of the present application. The target capacitance parameter is used to accurately adjust the output brightness of the lamp to achieve the calculated target lighting brightness requirement.

[0072] Lighting fixtures refer to lamps used to provide dynamic lighting effects in the working area. Compared with the traditional method of setting a capacitor for each lamp for control, this lighting fixture is controlled by a unified capacitor set on the main circuit, that is, a larger capacitor is set on the main circuit of the circuit, and the voltage stabilization function is achieved by discarding the capacitor of each lighting lamp. In this way, the capacitor on the main circuit can stabilize the input voltage and provide a suitable working voltage for the parallel lighting lamps. Using the capacitor on the main circuit to stabilize the input voltage can effectively suppress the fluctuation of the input voltage, so that the working voltage output to the lighting lamp remains at a relatively stable level, thereby avoiding the direct impact of excessive fluctuations in the input voltage on the lighting effect of the lighting lamp, such as flickering caused by voltage fluctuations. When the input voltage fluctuates, the capacitor can buffer and filter, so that the lamp obtains a smooth working voltage, avoiding flickering in the lighting, thereby improving the lighting effect.

[0073] Specifically, according to the target lighting brightness of the work area, the target capacitance parameter value of the corresponding lamp is searched in the preset mapping relationship. Then the system sets the target capacitance value to the capacitor of the lighting fixture controller in the work area to adjust the output brightness of the lamp. By controlling the capacitance parameter, the lighting brightness of the work area reaches the calculated optimal target value. This is done by reversely determining the lamp capacitance parameter required for dimming through the target brightness, and then accurately controlling the lamp based on the parameter to adjust the lighting of the work area to the optimal state that takes into account the user's visual fatigue and the ambient brightness. Through this process, the lighting equipment in the work area can be effectively and accurately controlled according to the target illumination requirements of intelligent calculation, so as to achieve the optimization of lighting conditions.

[0074] Based on the above embodiment, as an optional embodiment, in step 104: determining the target capacitance parameter of the lighting fixture in the working area according to the target lighting brightness, this step may also include the following steps: Step 401: Obtain the current lighting brightness of the lighting fixtures in the working area and compare the target lighting brightness with the lighting brightness; if the target lighting brightness is greater than or equal to the lighting brightness, then match the capacitor charging rate of the lighting fixture corresponding to the difference in the database according to the difference between the target lighting brightness and the lighting brightness.

[0075] The database refers to a storage device or module that stores parameter mapping relationships. In the embodiment of the present application, it can be understood as a database that pre-establishes and stores the mapping relationship between the lighting brightness difference and the lamp capacitor charging rate. The database is used to provide matching parameters between the brightness difference and the capacitor charging rate, providing a reference for adjusting the current brightness according to the target brightness.

[0076] The capacitor charging rate refers to the charging speed parameter of the capacitor used to adjust the output brightness of the lamp. In the embodiment of the present application, it can be understood as the rate value of the lamp capacitor charging obtained by matching the target brightness with the current brightness difference.

[0077] Specifically, the current output brightness of the lighting fixtures in the work area is monitored and compared with the calculated optimal target lighting brightness value to determine whether the target brightness is greater than or equal to the current brightness. If the target brightness is higher, the system will calculate the specific difference between the two and search for the capacitor charging rate parameter value of the model of the lighting fixture corresponding to the lighting brightness difference in the pre-established database of storage parameter mapping. This is done by comparing the current brightness with the target brightness to determine whether it needs to be increased and the specific increase range, and then selecting the appropriate capacitor charging rate according to the difference, dimming the lamp in a directional and forceful manner, and gradually optimizing the current actual brightness to the calculated optimal target brightness. Through this process, the real-time status of the lamps in the work area can be detected and compared according to the target illumination requirements of the intelligent calculation, and appropriate dimming control can be performed to continuously adjust the actual lighting effect to the optimal target effect.

[0078] Step 402: If the target lighting brightness is less than the lighting brightness, then according to the difference between the target lighting brightness and the lighting brightness, the capacitor discharge rate of the lighting fixture corresponding to the difference is matched in the database.

[0079] Among them, the capacitor discharge rate refers to the discharge speed parameter of the capacitor used to adjust the output brightness of the lamp. In the embodiment of the present application, it can be understood as the rate value of the lamp capacitor discharge obtained by matching the target brightness with the current brightness difference.

[0080] Specifically, in order to adjust the current actual brightness according to the intelligently calculated target lighting brightness, if the target brightness is lower than the current brightness, it is necessary to match the corresponding lamp capacitor discharge rate according to the difference between the two to dim and reduce the current brightness. When it is detected that the current actual output brightness of the lighting fixture in the work area is higher than the calculated optimal target lighting brightness, the specific difference between the two will be calculated, and the capacitor discharge rate parameter value of the lamp model corresponding to the lighting brightness difference will be searched in the pre-established database of storage parameter mapping relationship. This is done by judging that there is a gap between the current brightness and the target brightness, determining the specific amplitude that needs to be reduced later, and then selecting the appropriate capacitor discharge rate according to the difference, dimming the lamp in a directional and powerful manner, and gradually optimizing the current actual brightness to the calculated optimal target brightness. Through this process, according to the difference between the target illumination and the actual illumination, the matching capacitor discharge rate parameter can be selected for dimming control, and the current actual lighting brightness in the work area can be gradually adjusted to the optimal target illumination brightness.

[0081] Step 403: Correct the capacitor charging rate and the capacitor discharging rate to obtain target capacitance parameters of the lighting fixture.

[0082] Specifically, based on the usage of the workspace and historical data, the selected capacitor charging rate and discharge rate are corrected, such as compensating for environmental conditions and considering capacitor aging, to ensure that the capacitor parameter changes are stable and moderate. After correction, the system will use these processed and optimized capacitor charging / discharging rates as the final target capacitor parameters for the lamps in the workspace. This is done because directly matched parameters may have occasional anomalies and need to be adjusted appropriately. Appropriate correction of the capacitor charging / discharging rate can make the capacitor parameter control more stable and reliable. By correcting and optimizing the matched capacitor charging / discharging rate, the system can obtain more controllable and adjustable target capacitor parameters, thereby achieving smooth and gradual adjustment of the lighting fixtures in the workspace, so that the lighting brightness reaches and stabilizes at the optimized target state.

[0083] Based on the above embodiment, as an optional embodiment, in step 403: correcting the capacitor charging rate and the capacitor discharging rate to obtain the target capacitance parameter of the lighting fixture, this step may also include the following steps: Step 413: Obtain the current operating temperature and usage time of the lighting fixture; determine the temperature compensation amount based on the current operating temperature in the database, and determine the capacitor aging compensation amount based on the usage time.

[0084] Among them, the current working temperature and usage time refer to the temperature value of the lamp during the current actual working process and the total accumulated working time. In the embodiment of the present application, it can be understood as the working temperature data obtained by real-time monitoring of the lamp and the total usage time to date. The current working temperature and usage time are used to reflect the state of the lamp itself as the basis for determining the compensation amount.

[0085] The temperature compensation refers to the compensation value of the capacitor parameter determined according to the current working temperature of the lamp. In the embodiment of the present application, it can be understood as the corresponding capacitor parameter compensation value found in the preset database based on the detected real-time working temperature of the lamp. The temperature compensation is used to compensate for the influence of the temperature change of the lamp on the capacitor parameter and maintain the accuracy of the capacitor parameter control.

[0086] The capacitor aging compensation refers to the compensation value of the capacitor parameter determined according to the use time of the lamp. In the embodiment of the present application, it can be understood as the corresponding capacitor parameter compensation value found in the preset database based on the total use time of the lamp obtained by statistics. The capacitor aging compensation is used to compensate for the influence of the capacitor use time on the capacitor parameter control and maintain the accuracy of the capacitor parameter adjustment.

[0087] Specifically, in order to compensate for the impact of the state change of the lamp itself on the brightness control effect, it is necessary to detect and obtain the real-time working temperature and usage time of the lamp, and determine the temperature compensation and aging compensation of the capacitor parameters according to the temperature and usage time respectively. Real-time monitoring of the current working temperature data and the total usage time of the lighting fixtures in the work area. Based on the acquired temperature data, the system will search for the corresponding temperature compensation in the preset database parameter mapping relationship; based on the statistical usage time, the system will search for the matching capacitor aging compensation. This is because the increase in the working temperature of the lamp will affect the luminous effect, and long-term use will cause the capacitor parameters to decay. The introduction of temperature compensation and aging compensation can eliminate the interference of these state changes on precise dimming control. By obtaining the temperature and usage time of the lamp and determining the corresponding compensation amount, the system can improve the robustness of the lamp lighting adjustment and realize adaptive output adjustment under the condition of lamp state changes.

[0088] Step 423: Compensate the capacitor charging rate and the capacitor discharging rate according to the temperature compensation amount and the capacitor aging compensation amount to obtain the target capacitor charging rate and the target capacitor discharging rate of the lighting fixture; use the target capacitor charging rate and the target capacitor discharging rate as the target capacitor parameters of the lighting fixture.

[0089] Specifically, in order to obtain the target capacitance parameters that take into account the changes in the state of the lamp itself, it is necessary to compensate the matched capacitance charge / discharge rate based on the determined temperature compensation amount and capacitance aging compensation amount to obtain the final target capacitance charge / discharge rate of the lamp. According to the statistically obtained temperature compensation amount and capacitance aging compensation amount, the capacitance charging rate and discharge rate previously obtained by matching according to the brightness difference are corrected. After correction, the target capacitance charging rate and target capacitance discharge rate that take into account the actual state of the lamp are obtained, and these compensated and optimized capacitance charge / discharge rate parameters are determined as the final target capacitance parameters of the lamp. This is done to eliminate the influence of the change in the state of the lamp itself on the selection of capacitance parameters, obtain better controllable capacitance parameters for this specific lamp, and perform precise output adjustment. By performing temperature and aging compensation on the capacitance charge / discharge rate, the system can obtain target capacitance parameters customized for the state of the lamp, thereby achieving precise control of the lighting brightness of the work area.

[0090] On the basis of the above embodiment, the step of setting a capacitor in the main circuit is also included, and the specific steps include: Step 501: Obtain the number of lighting fixtures connected in parallel in the working area and the rated power of each lighting fixture; calculate the total lighting power in the working area based on the number and rated power of each lighting fixture; determine the capacitance parameters of the main circuit in the working area according to the total lighting power and a preset working voltage; and set a capacitor connected to each lighting fixture on the main circuit based on the capacitance parameters.

[0091] Among them, the capacitor refers to a large capacitor installed in the main circuit, which is connected to each parallel lighting fixture and is used to stabilize the input voltage to maintain a suitable working voltage for each lighting fixture in the working area, so as to replace the capacitors separately set for each lighting fixture. By setting the main circuit capacitor instead of setting multiple capacitors separately, a better voltage stabilization effect can be achieved, avoiding flickering and damage to lamps caused by voltage fluctuations, thereby optimizing the lighting effect.

[0092] Specifically, in order to achieve reasonable capacitance compensation for the lighting circuit in the working area, it is necessary to first accurately obtain various key information. The specific approach is to count the number n of lighting fixtures connected in parallel in the working area, and consult the product manuals of each lamp to record the rated power of each lamp. After that, the total lighting power in the working area is calculated according to the relationship between the number of lighting fixtures and the rated power. Then, according to the preset working voltage, the total lighting power formula is used to determine the corresponding required resistance value. Then, the required capacitance value is further derived based on the resistance value. After obtaining the required capacitance value, considering factors such as cost and ease of management, it is chosen to centrally set a large-capacity capacitor at the input end of the main lighting circuit in the working area, and its capacitance parameters meet the calculated capacitance value. This centralized capacitor setting method can provide effective power factor compensation for all lighting fixtures in the working area at the same time, thereby improving the efficiency of the regional lighting circuit and optimizing energy utilization.
