Description

Technical Field

[0001] This invention relates to the field of outdoor lighting control technology, specifically a linkage control system and control method for solar-powered outdoor lights. Background Technology

[0002] Solar outdoor lights are powered by crystalline silicon solar cells, stored in maintenance-free valve-regulated sealed batteries, and use ultra-high brightness LED lights as the light source. They are used to replace traditional public power streetlights and have the advantages of good stability, long life, and high luminous efficiency. They are also easy to install and maintain, have high safety performance, are energy-saving and environmentally friendly, and are economical and practical. They are widely used in urban main and secondary roads, residential areas, factories, tourist attractions, parking lots and other places.

[0003] Solar outdoor lights installed on urban roads convert electrical energy into light energy at night to illuminate the corresponding roads. Currently, when managing and controlling solar outdoor lights in the road monitoring area, the main method is to turn them on and off at set times through preset control programs. It is difficult to combine road monitoring analysis, road brightness performance analysis, and road brightness uniformity analysis, and it is impossible to achieve automatic and reasonable regulation of all solar outdoor lights in the road monitoring area, resulting in a low level of intelligence.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a linkage control system and control method for solar outdoor lights, which solves the problem that the existing technology is difficult to combine road monitoring and analysis, road brightness performance analysis and road brightness uniformity analysis, and cannot achieve automatic and reasonable control of all solar outdoor lights in the road monitoring area, resulting in low intelligence.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A linkage control system for solar outdoor lights includes a server, a data storage module, a road area division module, a road traffic monitoring module, a brightness performance analysis module, a brightness uniformity analysis module, and an outdoor light control module. The server is communicatively connected to the data storage module, the road area division module, the road traffic monitoring module, the brightness performance analysis module, the brightness uniformity analysis module, and the outdoor light control module.

[0008] The road area division module is used to obtain the road monitoring area, mark the solar outdoor lights in the road monitoring area as i, i = {1, 2, ..., n}, n represents the number of solar outdoor lights in the road monitoring area and n is a positive integer greater than 1; obtain the road area corresponding to solar outdoor light i, and mark the road area corresponding to solar outdoor light i as a sub-monitoring area.

[0009] The road traffic monitoring module is used to monitor and analyze the road monitoring area and generate first-level, second-level, or third-level road monitoring signals. These signals are then sent to the brightness performance analysis module via a server. The brightness performance analysis module analyzes the brightness of the road monitoring area and generates either a qualified or unqualified brightness performance signal. When generating an unqualified brightness performance signal, it uses brightness difference analysis to generate either a qualified or unqualified brightness difference signal. Both the qualified and unqualified brightness performance signals, along with the qualified and unqualified brightness difference signals, are then sent to the server.

[0010] When the server receives a signal indicating that the area brightness performance is qualified, it generates a brightness uniformity analysis signal and sends the brightness uniformity analysis signal to the brightness uniformity analysis module. After receiving the brightness uniformity analysis signal, the brightness uniformity analysis module performs brightness uniformity analysis on the road monitoring area and generates a brightness uniformity qualified signal or a brightness uniformity unqualified signal, and sends the brightness uniformity qualified signal or brightness uniformity unqualified signal to the server.

[0011] When the server receives a signal indicating that the area brightness performance is unqualified, the brightness difference is unqualified, or the brightness uniformity is unqualified, it generates a corresponding outdoor light control signal and sends it to the outdoor light control module. The outdoor light control module then controls the corresponding solar outdoor light. When the server receives a signal indicating that the brightness difference is qualified or the brightness uniformity is qualified, it does not generate an outdoor light control signal.

[0012] Furthermore, the monitoring and analysis process of the road traffic monitoring module includes:

[0013] The system acquires the number of vehicles and pedestrians within the road monitoring area during the detection period and marks them as actual vehicle value and actual pedestrian value, respectively. The actual vehicle value and actual pedestrian value are then used to calculate the initial road inspection value. The system retrieves the preset initial road inspection range through the data storage module and compares the initial road inspection value with the preset initial road inspection range. If the initial road inspection value is greater than or equal to the maximum value of the preset initial road inspection range, a road inspection signal SJ1 is generated. If the initial road inspection value is within the preset initial road inspection range, a road inspection signal SJ2 is generated. If the initial road inspection value is less than or equal to the minimum value of the preset initial road inspection range, a road inspection signal SJ3 is generated.

[0014] Vehicle and pedestrian speed change values ​​are obtained through road change analysis. These values ​​are then used to calculate the road speed change value. A preset road speed change threshold is retrieved through the data storage module. The road speed change value is compared with the preset threshold. If the road speed change value is greater than or equal to the preset threshold, a road speed change signal BS1 is generated. If the road speed change value is less than the preset threshold, a road speed change signal BS2 is generated. The initial road detection signal and the road speed change signal are then subjected to signal intersection analysis to generate a first-level, second-level, or third-level road monitoring signal.

[0015] Furthermore, the specific analysis process of road change analysis is as follows:

[0016] The system obtains the number of vehicles entering and leaving the road monitoring area during the detection period and marks them as entry and exit values, and obtains the number of pedestrians entering and leaving the road monitoring area during the detection period and marks them as entry and exit values.

[0017] The difference between the number of vehicles entering and exiting the road monitoring area during the detection period is used to calculate the vehicle speed change value. The difference between the number of people entering and exiting the road monitoring area during the detection period is used to calculate the pedestrian speed change value. The duration of the detection period is obtained and marked as the detection duration. The ratio between the vehicle speed change value and the detection duration is used to calculate the vehicle speed change value. The ratio between the pedestrian speed change value and the detection duration is used to calculate the pedestrian speed change value.

[0018] Furthermore, the specific analysis process of signal intersection analysis is as follows:

[0019] If the initial road detection signal SJ1, SJ2, or SJ3 and the road speed change signal BS1 or BS2 are obtained, a first-level road monitoring signal is generated if SJ1∩BS1, SJ1∩BS2, or SJ2∩BS1 is obtained; a second-level road monitoring signal is generated if SJ2∩BS2 or SJ3∩BS1 is obtained; and a third-level road monitoring signal is generated if SJ3∩BS2 is obtained.

[0020] Furthermore, the brightness analysis process of the brightness performance analysis module includes:

[0021] The brightness value of the sub-monitoring area during the detection period is obtained and marked as the lamp performance value. The road monitoring signal is obtained and the corresponding preset lamp performance threshold is retrieved based on the road monitoring signal. The lamp performance value is compared with the corresponding preset lamp performance threshold. If the lamp performance value is greater than or equal to the corresponding preset lamp performance threshold, the solar outdoor lamp i corresponding to the corresponding sub-monitoring area is marked as a qualified lamp. If the lamp performance value is less than the corresponding preset lamp performance threshold, the solar outdoor lamp i corresponding to the corresponding sub-monitoring area is marked as a substandard lamp.

[0022] If all solar outdoor lights i in the road monitoring area are qualified light sources, a qualified brightness signal for the area will be generated; if there are unqualified light sources in the road monitoring area, an unqualified brightness signal for the area will be generated. When an unqualified brightness signal for the area is generated, a qualified brightness signal or an unqualified brightness signal will be generated through brightness difference analysis.

[0023] Furthermore, the specific analysis process of brightness difference analysis is as follows:

[0024] The system acquires the non-compliant light sources within the road monitoring area, along with their brightness performance values. It then calculates the difference between these brightness performance values ​​and a preset brightness performance threshold, taking the absolute value to obtain a brightness difference table value. The system retrieves the preset brightness difference table threshold through the data storage module and compares the brightness difference table value with this threshold. If a non-compliant light source's brightness difference table value is greater than or equal to the preset brightness difference table threshold, a brightness difference failure signal is generated.

[0025] If the brightness difference values ​​of all non-compliant lamps are less than the preset brightness difference threshold, the distance between two adjacent groups of non-compliant lamps is marked as the light difference distance value. The preset light difference distance threshold is retrieved through the data storage module, and the light difference distance value is compared with the preset light difference distance threshold. If all light difference distance values ​​are greater than or equal to the preset light difference distance threshold, a brightness difference qualified signal is generated; otherwise, a brightness difference unqualified signal is generated.

[0026] Furthermore, the brightness uniformity analysis process of the brightness uniformity analysis module includes:

[0027] The system obtains the illumination performance value of solar outdoor light i, calculates the difference between the illumination performance value and the corresponding preset illumination performance threshold to obtain the invalid brightness consumption value, retrieves the preset invalid brightness consumption threshold through the data storage module, and compares the invalid brightness consumption value with the preset invalid brightness consumption threshold. If the invalid brightness consumption value is less than the preset invalid brightness consumption threshold, the invalid brightness consumption of the corresponding solar outdoor light i is judged to be normal. If the invalid brightness consumption value is greater than or equal to the preset invalid brightness consumption threshold, the invalid brightness consumption of the corresponding solar outdoor light i is judged to be abnormal.

[0028] If there is an invalid light consumption abnormality of solar outdoor light i, a brightness uniformity failure signal is generated; if there is no invalid light consumption abnormality of solar outdoor light i, a brightness performance set is established for the brightness performance values ​​of all solar outdoor light i, and the variance of the brightness performance set is calculated to obtain the brightness deviation value; the preset brightness deviation threshold is retrieved through the data storage module, and the brightness deviation value is compared with the preset brightness deviation threshold. If the brightness deviation value is greater than or equal to the preset brightness deviation threshold, a brightness uniformity failure signal is generated; if the brightness deviation value is less than the preset brightness deviation threshold, a brightness uniformity qualified signal is generated.

[0029] Furthermore, the specific process of retrieving the corresponding preset light illumination threshold based on road monitoring signals is as follows:

[0030] The system acquires road monitoring signals and preset light performance thresholds. These preset light performance thresholds include a first-level preset light performance threshold, a second-level preset light performance threshold, and a third-level preset light performance threshold. These thresholds correspond to the first-level, second-level, and third-level road monitoring signals, respectively, with the first-level preset light performance threshold being greater than the second-level preset light performance threshold, and the second-level preset light performance threshold being greater than the third-level preset light performance threshold.

[0031] Furthermore, the server communicates with the lamp monitoring terminal. The server sends signals indicating that the area brightness performance is unqualified, the brightness uniformity is unqualified, or the brightness uniformity is qualified to the lamp monitoring terminal. When the monitoring personnel at the lamp monitoring terminal receive the relevant signals, they can manually adjust the outdoor lights as needed.

[0032] The linkage control method for this solar outdoor light includes the following steps:

[0033] Step 1: Obtain the road monitoring area and mark the road area corresponding to the solar outdoor light i within the road monitoring area as a sub-monitoring area;

[0034] Step 2: Monitor and analyze the road monitoring area to generate Level 1, Level 2, or Level 3 road monitoring signals, and send them to the brightness performance analysis module via the server;

[0035] Step 3: Perform brightness analysis on the road monitoring area and generate a signal indicating that the area brightness performance is qualified or unqualified. When generating a signal indicating that the area brightness performance is unqualified, generate a signal indicating that the brightness difference is qualified or unqualified through brightness difference analysis. Send the signal indicating that the area brightness performance is qualified or unqualified, as well as the signal indicating that the brightness difference is qualified or unqualified, to the server.

[0036] Step 4: When the server receives the signal that the brightness performance of the area is qualified, it sends the brightness uniformity analysis signal to the brightness uniformity analysis module; the brightness uniformity analysis module performs brightness uniformity analysis on the road monitoring area and generates a brightness uniformity qualified signal or a brightness uniformity unqualified signal, and sends the brightness uniformity qualified signal or brightness uniformity unqualified signal to the server.

[0037] Step 5: When the server receives a signal indicating unqualified brightness difference or unqualified brightness uniformity, the outdoor light control module adjusts the corresponding solar outdoor light i. When the server receives a signal indicating qualified brightness difference or qualified brightness uniformity, it does not adjust the outdoor light.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. In this invention, the road traffic monitoring module monitors and analyzes the road monitoring area and generates a first-level road monitoring signal, a second-level road monitoring signal, or a third-level road monitoring signal. The corresponding road monitoring signal is sent to the brightness performance analysis module via the server. The brightness performance analysis module analyzes the brightness of the road monitoring area and generates a signal indicating that the area's brightness performance is qualified or unqualified. Combining road monitoring analysis with brightness analysis helps in the subsequent linkage control of solar outdoor lights.

[0040] 2. In this invention, when a signal indicating unqualified brightness performance in a generated area is generated, a signal indicating qualified brightness performance or unqualified brightness performance is generated through brightness difference analysis. When a signal indicating qualified brightness performance in a generated area is generated, a brightness uniformity analysis module is used to perform brightness uniformity analysis on the road monitoring area and generate a signal indicating qualified brightness uniformity or unqualified brightness uniformity. When the server receives a signal indicating unqualified brightness performance or unqualified brightness uniformity, it uses an outdoor light control module to control the corresponding solar outdoor light i. This not only achieves reasonable control of brightness within the road monitoring area, ensuring smooth traffic flow while also helping to reduce energy consumption, but also helps to achieve coordinated control of all solar outdoor lights within the road monitoring area, demonstrating a high degree of intelligence.

[0041] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings;

[0042] Figure 1 This is an overall system block diagram of the present invention;

[0043] Figure 2 This is a communication block diagram of Embodiment 2 of the present invention;

[0044] Figure 3 This is a flowchart of the method of the present invention. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] like Figure 1 As shown, the present invention proposes a linkage control system for solar outdoor lights, including a server. The server is communicatively connected to a data storage module, a road area division module, a road traffic monitoring module, a brightness performance analysis module, a brightness uniformity analysis module, and an outdoor light control module. The road area division module is used to obtain the road monitoring area, mark the solar outdoor lights in the road monitoring area as i, i = {1, 2, ..., n}, where n represents the number of solar outdoor lights in the road monitoring area and n is a positive integer greater than 1; obtain the road area corresponding to solar outdoor light i, and mark the road area corresponding to solar outdoor light i as a sub-monitoring area.

[0048] The road traffic monitoring module monitors and analyzes the road monitoring area and generates primary, secondary, or tertiary road monitoring signals. The monitoring and analysis process of the road traffic monitoring module is as follows:

[0049] Step S1: Obtain the number of vehicles and pedestrians within the road monitoring area during the detection period and label them as the actual vehicle value SC and the actual pedestrian value SR, respectively. Then, use the formula... The actual vehicle value SC and the actual person value SR are substituted into the numerical calculation, and the initial road inspection value DCz is obtained through the numerical calculation.

[0050] Wherein, a1 and a2 are preset proportional coefficients, and the values ​​of a1 and a2 are both greater than zero and a1>a2; it should be noted that the value of the initial road detection value DCz is directly proportional to the actual vehicle value SC and the actual person value SR. The larger the value of the actual vehicle value SC and the larger the value of the actual person value SR, the larger the value of the initial road detection value DCz, indicating that the road conditions in the road monitoring area are more congested during the detection period, and the more necessary it is to keep the road monitoring area brighter.

[0051] Step S2: Retrieve the preset road initial inspection range through the data storage module, compare the road initial inspection value DCz with the preset road initial inspection range, and generate a road actual inspection signal SJ1 if the road initial inspection value DCz is greater than or equal to the maximum value of the preset road initial inspection range, generate a road actual inspection signal SJ2 if the road initial inspection value DCz is within the preset road initial inspection range, and generate a road actual inspection signal SJ3 if the road initial inspection value DCz is less than or equal to the minimum value of the preset road initial inspection range.

[0052] Step S3: Obtain the number of vehicles entering the road monitoring area and the number of vehicles leaving the road monitoring area during the detection period, and mark the number of vehicles entering the road monitoring area and the number of vehicles leaving the road monitoring area during the detection period as the entry value and the exit value, respectively. Also, obtain the number of pedestrians entering the road monitoring area and the number of pedestrians leaving the road monitoring area during the detection period, and mark the number of pedestrians entering the road monitoring area and the number of pedestrians leaving the road monitoring area during the detection period as the entry value and the exit value, respectively.

[0053] Step S4: Calculate the difference between the vehicle entry value and the vehicle exit value in the road monitoring area during the detection period to obtain the vehicle change value CB; calculate the difference between the pedestrian entry value and the pedestrian exit value in the road monitoring area during the detection period to obtain the pedestrian change value RB; obtain the duration of the detection period and mark it as the detection duration; calculate the ratio between the vehicle change value CB and the detection duration to obtain the vehicle speed change value CS; calculate the ratio between the pedestrian change value RB and the detection duration to obtain the pedestrian speed change value RS.

[0054] Step S5: Perform numerical calculations using the formula LBz = a3 * CS + a4 * RS, and substitute the vehicle shift value CS and the pedestrian shift value RS. The road shift value LBz is obtained after numerical calculation. Here, a3 and a4 are preset weighting coefficients, and the values ​​of a3 and a4 are both greater than zero and a3 > a4.

[0055] It should be noted that the value of the road shift value LBz is directly proportional to both the vehicle shift value CS and the pedestrian shift value RS. The larger the value of the vehicle shift value CS and the larger the value of the pedestrian shift value RS, the larger the value of the road shift value LBz during the corresponding detection period. This indicates that the growth rate of vehicles and pedestrians entering the road monitoring area during the detection period is faster, and the road monitoring area tends to become more and more congested in the subsequent period.

[0056] The preset road speed change threshold is retrieved through the data storage module. The road speed change value LBz is compared with the road speed change threshold. If the road speed change value LBz is greater than or equal to the preset road speed change threshold, the road speed change signal BS1 is generated. If the road speed change value LBz is less than the preset road speed change threshold, the road speed change signal BS2 is generated.

[0057] Step S6: Perform signal intersection analysis between the initial road detection signal and the road speed change signal to obtain the initial road detection signal SJ1, SJ2, or SJ3 and the road speed change signal BS1 or BS2. If SJ1∩BS1, SJ1∩BS2, or SJ2∩BS1 is obtained, a Level 1 road monitoring signal is generated. If SJ2∩BS2 or SJ3∩BS1 is obtained, a Level 2 road monitoring signal is generated. If SJ3∩BS2 is obtained, a Level 3 road monitoring signal is generated. The road traffic monitoring module sends the Level 1, Level 2, or Level 3 road monitoring signals to the server. The server then sends the Level 1, Level 2, or Level 3 road monitoring signals to the brightness performance analysis module.

[0058] The brightness performance analysis module performs brightness analysis on the road monitoring area and generates a signal indicating whether the area's brightness performance is acceptable or unacceptable. Furthermore, when generating an unacceptable brightness performance signal, it uses brightness difference analysis to generate a signal indicating whether the brightness difference is acceptable or unacceptable. The specific analysis process of the brightness performance analysis module is as follows:

[0059] Step G1: Obtain the brightness value of the sub-monitoring area during the detection period and mark it as the light performance value DBi. Obtain the road monitoring signal and retrieve the corresponding preset light performance threshold based on the road monitoring signal. The preset light performance threshold includes a first-level preset light performance threshold, a second-level preset light performance threshold, and a third-level preset light performance threshold. The first-level preset light performance threshold, the second-level preset light performance threshold, and the third-level preset light performance threshold correspond to the first-level road monitoring signal, the second-level road monitoring signal, and the third-level road monitoring signal, respectively.

[0060] Among them, the value of the first-level preset light performance threshold is greater than the value of the second-level preset light performance threshold, the value of the second-level preset light performance threshold is greater than the value of the third-level preset light performance threshold, and the values ​​of the first-level preset light performance threshold, the second-level preset light performance threshold, and the third-level preset light performance threshold are all positive numbers.

[0061] Step G2: Compare the light performance value DBi with the corresponding preset light performance threshold. If the light performance value DBi is greater than or equal to the corresponding preset light performance threshold, it indicates that the luminous brightness of the corresponding solar outdoor light i meets the current requirements. Then, mark the solar outdoor light i corresponding to the corresponding sub-monitoring area as a qualified light body. If the light performance value DBi is less than the corresponding preset light performance threshold, it indicates that the luminous brightness of the corresponding solar outdoor light i does not meet the current requirements. Then, mark the solar outdoor light i corresponding to the corresponding sub-monitoring area as a non-qualified light body.

[0062] Step G3: If all solar outdoor lights i in the road monitoring area are qualified light sources, a qualified area brightness performance signal is generated; if there are unqualified light sources in the road monitoring area, an unqualified area brightness performance signal is generated.

[0063] When generating a signal indicating that the brightness performance of a region is substandard, all non-compliant luminous lamps within the road monitoring area are acquired, along with their brightness performance values ​​DBi. The difference between the brightness performance values ​​DBi and the preset brightness performance threshold is calculated, and the absolute value is taken to obtain the brightness difference table value LCI. It should be noted that the larger the value of the brightness difference table value LCI, the greater the deviation of the brightness of the corresponding non-compliant luminous lamp from the preset brightness requirement, and the worse the corresponding brightness effect.

[0064] Step G4: Retrieve the preset brightness difference table threshold through the data storage module, and compare the brightness difference table value LCI with the preset brightness difference table threshold. If the brightness difference table value LCI of any non-compliant lamp is greater than or equal to the preset brightness difference table threshold, a brightness difference failure signal is generated. If the brightness difference table value LCI of all non-compliant lamps is less than the preset brightness difference table threshold, the distance between two adjacent groups of non-compliant lamps is marked as the light difference distance value GJ. It should be noted that the smaller the value of the light difference distance value GJ, the fewer the number of compliant lamps between two adjacent groups of non-compliant lamps, and the greater the adverse impact on road safety.

[0065] Step G5: Retrieve the preset light difference distance threshold through the data storage module, compare the light difference distance value GJ with the preset light difference distance threshold. If all light difference distance values ​​GJ are greater than or equal to the preset light difference distance threshold, a brightness difference qualified signal is generated; otherwise, a brightness difference unqualified signal is generated.

[0066] The brightness performance analysis module sends signals indicating whether the area brightness performance is acceptable or unacceptable, as well as signals indicating whether the brightness difference is acceptable or unacceptable, to the server. Upon receiving a signal indicating acceptable area brightness performance, the server generates a brightness uniformity analysis signal and sends it to the brightness uniformity analysis module. Upon receiving the brightness uniformity analysis signal, the brightness uniformity analysis module performs brightness uniformity analysis on the road monitoring area and generates a brightness uniformity acceptable or unacceptable signal. The specific brightness uniformity analysis process is as follows:

[0067] Step Q1: Obtain the brightness performance value DBi of the solar outdoor light i. Calculate the difference between the brightness performance value DBi and the corresponding preset brightness performance threshold to obtain the invalid brightness consumption value LHi. It should be noted that the larger the invalid brightness consumption value LHi is, the greater the deviation of the corresponding solar outdoor light i from the preset brightness requirement, and the greater the energy wasted.

[0068] Step Q2: Retrieve the preset invalid light consumption threshold through the data storage module, and compare the invalid light consumption value LHi with the preset invalid light consumption threshold. If the invalid light consumption value LHi is less than the preset invalid light consumption threshold, it is determined that the invalid light consumption of the corresponding solar outdoor light i is normal. If the invalid light consumption value LHi is greater than or equal to the preset invalid light consumption threshold, it is determined that the invalid light consumption of the corresponding solar outdoor light i is abnormal.

[0069] Step Q3: If there is an invalid light consumption abnormality of solar outdoor light i, then generate a brightness uniformity failure signal; if there is no invalid light consumption abnormality of solar outdoor light i, then establish a brightness performance set LJ for the brightness performance values ​​DBi of all solar outdoor light i, the brightness performance set LJ = {DB1, DB2, ..., DBn}; perform variance calculation on the brightness performance set LJ, and obtain the brightness deviation value LP after variance calculation.

[0070] Step Q4: Retrieve the preset brightness deviation threshold through the data storage module, and compare the brightness deviation value LP with the preset brightness deviation threshold. If the brightness deviation value LP is greater than or equal to the preset brightness deviation threshold, a brightness uniformity failure signal is generated. If the brightness deviation value LP is less than the preset brightness deviation threshold, a brightness uniformity success signal is generated.

[0071] The brightness uniformity analysis module sends either a brightness uniformity pass signal or a brightness uniformity fail signal to the server. When the server receives a brightness difference fail signal or a brightness uniformity fail signal, it generates a corresponding outdoor light control signal and sends it to the outdoor light control module. The outdoor light control module then controls the corresponding solar outdoor light i to achieve reasonable brightness control within the road monitoring area. This ensures smooth traffic flow while also reducing energy consumption and enabling coordinated control of all solar outdoor lights within the road monitoring area. When the server receives a brightness difference pass signal or a brightness uniformity pass signal, it does not generate an outdoor light control signal.

[0072] The above formulas are all dimensionless calculations. The formulas are derived from software simulations based on a large amount of collected data to obtain the most recent real-world results. The preset parameters in the formulas are set by those skilled in the art according to the actual situation.

[0073] Example 2:

[0074] like Figure 2As shown, the difference between this embodiment and Embodiment 1 is that the server communicates with the lamp monitoring terminal. When the server receives a signal indicating unqualified brightness, unqualified brightness uniformity, or qualified brightness uniformity, it sends the signal indicating unqualified regional brightness performance, unqualified brightness uniformity, or qualified brightness uniformity to the lamp monitoring terminal. When the monitoring personnel at the lamp monitoring terminal receive the relevant signals, they can manually adjust the outdoor lamps as needed. This facilitates manual adjustment and helps the monitoring personnel at the lamp monitoring terminal to grasp the analysis information of the corresponding road monitoring area.

[0075] Example 3:

[0076] like Figure 3 As shown, the difference between this embodiment and Embodiments 1 and 2 is that this invention proposes a linkage control method for solar outdoor lights, including the following steps:

[0077] Step 1: Obtain the road monitoring area and mark the road area corresponding to the solar outdoor light i within the road monitoring area as a sub-monitoring area;

[0078] Step 2: Monitor and analyze the road monitoring area to generate Level 1, Level 2, or Level 3 road monitoring signals, and send them to the brightness performance analysis module via the server;

[0079] Step 3: Perform brightness analysis on the road monitoring area and generate a signal indicating that the area brightness performance is qualified or unqualified. When generating a signal indicating that the area brightness performance is unqualified, generate a signal indicating that the brightness difference is qualified or unqualified through brightness difference analysis. Send the signal indicating that the area brightness performance is qualified or unqualified, as well as the signal indicating that the brightness difference is qualified or unqualified, to the server.

[0080] Step 4: When the server receives the signal that the brightness performance of the area is qualified, it sends the brightness uniformity analysis signal to the brightness uniformity analysis module; the brightness uniformity analysis module performs brightness uniformity analysis on the road monitoring area and generates a brightness uniformity qualified signal or a brightness uniformity unqualified signal, and sends the brightness uniformity qualified signal or brightness uniformity unqualified signal to the server.

[0081] Step 5: When the server receives a signal indicating unqualified brightness difference or unqualified brightness uniformity, the outdoor light control module adjusts the corresponding solar outdoor light i. When the server receives a signal indicating qualified brightness difference or qualified brightness uniformity, it does not adjust the outdoor light. This enables the coordinated control of all solar outdoor lights within the road monitoring area, which helps ensure normal and safe passage within the road monitoring area.

[0082] The working principle of this invention is as follows: During use, the road traffic monitoring module monitors and analyzes the road monitoring area, generating first-level, second-level, or third-level road monitoring signals. The brightness performance analysis module analyzes the brightness of the road monitoring area and generates a qualified or unqualified brightness performance signal. When an unqualified brightness performance signal is generated, a brightness difference analysis module generates a qualified or unqualified brightness difference signal. When a qualified brightness performance signal is generated, a brightness uniformity analysis module analyzes the brightness uniformity of the road monitoring area and generates a qualified or unqualified brightness uniformity signal. When the server receives an unqualified brightness difference signal or a unqualified brightness uniformity signal, the outdoor light control module controls the corresponding solar outdoor light. When the server receives a qualified brightness difference signal or a qualified brightness uniformity signal, it does not generate an outdoor light control signal. This achieves reasonable control of brightness within the road monitoring area, ensuring smooth traffic flow while reducing energy consumption and enabling coordinated control of all solar outdoor lights within the road monitoring area.

When generating an unqualified brightness performance signal for the area, it generates a qualified or unqualified brightness difference signal through brightness difference analysis and sends the qualified or unqualified brightness performance signal for the area and the qualified or unqualified brightness difference signal for the area to the server. When the server receives a signal indicating that the area brightness performance is qualified, it generates a brightness uniformity analysis signal and sends the brightness uniformity analysis signal to the brightness uniformity analysis module. After receiving the brightness uniformity analysis signal, the brightness uniformity analysis module performs brightness uniformity analysis on the road monitoring area and generates a brightness uniformity qualified signal or a brightness uniformity unqualified signal, and sends the brightness uniformity qualified signal or brightness uniformity unqualified signal to the server. When the server receives a signal indicating that the area brightness performance is not up to standard, the brightness difference is not up to standard, or the brightness uniformity is not up to standard, it generates a corresponding outdoor light control signal and sends the corresponding outdoor light control signal to the outdoor light control module. The outdoor light control module then controls the corresponding solar outdoor light. The server does not generate an outdoor light control signal when it receives a brightness difference pass signal or a brightness uniformity pass signal. The brightness analysis process of the brightness performance analysis module includes: The brightness value of the sub-monitoring area during the detection period is obtained and marked as the lamp performance value. The road monitoring signal is obtained and the corresponding preset lamp performance threshold is retrieved based on the road monitoring signal. The lamp performance value is compared with the corresponding preset lamp performance threshold. If the lamp performance value is greater than or equal to the corresponding preset lamp performance threshold, the solar outdoor lamp i corresponding to the corresponding sub-monitoring area is marked as a qualified lamp. If the lamp performance value is less than the corresponding preset lamp performance threshold, the solar outdoor lamp i corresponding to the corresponding sub-monitoring area is marked as a substandard lamp. If all solar outdoor lights i in the road monitoring area are qualified light sources, a qualified area brightness performance signal is generated; if there are unqualified light sources in the road monitoring area, an unqualified area brightness performance signal is generated. When an unqualified area brightness performance signal is generated, a qualified or unqualified brightness difference signal is generated through brightness difference analysis. The specific analysis process of brightness difference analysis is as follows: The system acquires the non-compliant light sources within the road monitoring area, along with their illumination performance values. It then calculates the difference between these illumination performance values ​​and a preset illumination performance threshold, taking the absolute value to obtain the illumination difference table value. Finally, it retrieves the preset illumination difference table threshold value through the data storage module and compares the illumination difference table value with the preset illumination difference table threshold value. If the brightness difference value of any non-compliant lamp is greater than or equal to the preset brightness difference threshold, a brightness difference failure signal is generated. If the brightness difference values ​​of all non-compliant lamps are less than the preset brightness difference threshold, the distance between two adjacent groups of non-compliant lamps is marked as the light difference distance value. The preset light difference distance threshold is retrieved through the data storage module, and the light difference distance value is compared with the preset light difference distance threshold. If all light difference distance values ​​are greater than or equal to the preset light difference distance threshold, a brightness difference pass signal is generated; otherwise, a brightness difference failure signal is generated.

The actual vehicle value and actual pedestrian value are then used to calculate the initial road inspection value. The system retrieves the preset initial road inspection range through the data storage module and compares the initial road inspection value with the preset initial road inspection range. If the initial road inspection value is greater than or equal to the maximum value of the preset initial road inspection range, a road inspection signal SJ1 is generated. If the initial road inspection value is within the preset initial road inspection range, a road inspection signal SJ2 is generated. If the initial road inspection value is less than or equal to the minimum value of the preset initial road inspection range, a road inspection signal SJ3 is generated. Vehicle and pedestrian speed change values ​​are obtained through road change analysis. These values ​​are then used to calculate the road speed change value. A preset road speed change threshold is retrieved through the data storage module. The road speed change value is compared with the preset threshold. If the road speed change value is greater than or equal to the preset threshold, a road speed change signal BS1 is generated. If the road speed change value is less than the preset threshold, a road speed change signal BS2 is generated. The initial road detection signal and the road speed change signal are then subjected to signal intersection analysis to generate a first-level, second-level, or third-level road monitoring signal.

The difference between the number of vehicles entering and exiting the road monitoring area during the detection period is used to calculate the vehicle change value, and the difference between the number of people entering and exiting the road monitoring area during the detection period is used to calculate the person change value. The duration of the detection period is obtained and marked as the detection duration.

If the invalid brightness consumption value is less than the preset invalid brightness consumption threshold, the invalid brightness consumption of the corresponding solar outdoor light i is judged to be normal. If the invalid brightness consumption value is greater than or equal to the preset invalid brightness consumption threshold, the invalid brightness consumption of the corresponding solar outdoor light i is judged to be abnormal. If there is an invalid light consumption abnormality of solar outdoor light i, a brightness uniformity failure signal is generated; if there is no invalid light consumption abnormality of solar outdoor light i, a brightness performance set is established for the brightness performance values ​​of all solar outdoor light i, and the variance of the brightness performance set is calculated to obtain the brightness deviation value; the preset brightness deviation threshold is retrieved through the data storage module, and the brightness deviation value is compared with the preset brightness deviation threshold.
