Description

Technical Field

[0001] The present invention relates to the field of street lamp management, and particularly to a digital platform for an Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp. Background Art

[0002] Street lamps are key facilities installed on public roads to provide lighting at night or under other low-light conditions, aiming to ensure traffic safety, enhance public safety, and beautify the urban landscape. Some new types of street lamps also integrate multiple functions such as Wi-Fi hotspots, environmental monitoring, and charging piles, becoming an important part of the infrastructure of smart cities.

[0003] To improve the practicality of street lamps and reduce costs, introducing a scheme of alternating use of batteries and mains power is an innovative and effective strategy. For example, the first national demonstration project of "energy storage and charging integrated" intelligent street lamps was put into grid-connected operation in Shuangliu District, Chengdu. The characteristics of these street lamps are mainly to charge during the low-peak period of electricity consumption at night and send electricity to the power grid during the peak period of electricity consumption. This project is a scientific and technological achievement transformation project jointly carried out by the government and enterprises in Shuangliu District. It is located on Jinhe Road in Shuangliu District and is built using intelligent street lamps developed and produced by Huati Technology. In the initial stage of the project, 4 sets of intelligent street lamp systems were piloted and put into operation. Each lamp post is equipped with a 40-kilowatt-hour energy storage battery and is connected to the low-voltage side of a nearby public transformer through the grid.

[0004] Another example is the Chinese invention patent with the authorization publication number CN103634977B, which discloses an intelligent management system for energy storage LED street lamps, including an energy storage device, an energy storage control device, a lighting device, a lighting control device, and a communication device; the energy storage device is electrically connected to the energy storage control device, the external power grid, and the lighting device respectively; the lighting device is electrically connected to the energy storage device and the external power grid; the control output interface of the lighting control device is electrically connected to the lighting device, and the communication interface is communicatively connected to the communication device; the communication device is communicatively connected to the terminal control device; the lighting device is an LED street lamp. An energy storage module is provided to charge the energy storage device during the low-peak period of electricity consumption and at a lower electricity price, and the energy storage device discharges during the peak period of electricity consumption and at a higher electricity price, so as to supplement the power grid and play a role in peak shaving and valley filling.

[0005] However, although this hybrid power supply mode brings significant economic benefits, it also increases the complexity of maintenance management and labor consumption, and greatly reduces the practicality. Summary of the Invention

Each column of the multi-primary-color light-emitting unit matrix includes single-primary-color light-emitting units of two primary colors. The single-primary-color light-emitting unit is any one of white, green, yellow, blue, and red primary-color light-emitting units, and any two primary-color light-emitting units among red, blue, and green are not adjacent.

[0026] The second aspect of the present invention is to provide an Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp digital platform. The digital platform includes: a number of Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamps, a remote control center; wherein, each of the intelligent street lamps includes a lighting module, a power storage module, a public power module, and an Internet of Things controller;

[0028] The public power module is used to obtain the power supply of the public power grid. The public power module further includes a first power supply interface corresponding to the public power grid, and the first power supply interface is used to supply power to the lighting module and / or the power storage module during the first time period;

[0029] The power storage module is used to obtain and store electric energy through the first power supply interface during the first time period. The power storage module includes a second power supply interface, and the second power supply interface is used to supply power to the lighting module during the second time period;

[0030] The Internet of Things controller communicates with the remote control center to implement the steps of the control method of the Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp as described in any embodiment of the present invention.

[0031] Beneficial technical effects:

[0032] The present invention provides a centralized maintenance method for peak-shifting energy storage electric lights that ensures the safety and utilization rate of facilities while reducing costs, and specifically provides a control method for Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lights.

[0033] First, based on the accurate and rapid assessment of the loss rate of the energy storage module, the situation of battery performance degradation is identified, and the dynamic response of the maintenance work order is realized. When a fault risk is detected, the maintenance priority can be immediately adjusted, and high-risk areas can be given priority to ensure that safety issues are resolved in a timely manner, reducing potential safety hazards, helping to reduce the occurrence frequency of sudden failures, and avoiding large-scale replacement requirements due to battery aging, thus significantly reducing the long-term maintenance cost.

[0034] On this basis, a multi-level battery performance monitoring mechanism is provided, and different monitoring frequencies are adopted according to the status of different street lights to improve the response speed and accuracy of the adjustment of the maintenance work order, and further realize the high adaptability of the maintenance work arrangement to the current scenario.

[0035] Normal state: Regular monitoring is carried out at a relatively long time interval (the first time interval) to ensure the normal operation of the equipment while saving resources and reducing unnecessary data processing burdens.

[0036] Inefficient state: The monitoring time interval (the second time interval) is shortened, and inefficient street lights are monitored more frequently to ensure the safe operation of inefficient street lights during the postponed maintenance period.

[0037] Abnormal state: The monitoring time interval (the third time interval) is further shortened. When the loss rate of a certain inefficient street light is abnormal, high-frequency monitoring is carried out on the battery suspected of having a safety risk to improve the reaction speed to the battery safety risk.

[0038] Furthermore, a maintenance strategy based on cost-benefit analysis and multi-dimensional adjustment is provided. The flexible and targeted maintenance arrangement improves the efficiency and response speed of the maintenance work and realizes the optimal allocation of resources. On the one hand, street light maintenance is centrally carried out in each planned area according to the maintenance work order. Considering the energy storage module efficiency, additional electricity price cost and actual maintenance operation cost, the maintenance time and resource allocation are optimized. Then, according to the comparison between the cost required for maintenance and the benefit after maintenance, resources are reasonably allocated to make the maintenance work more economical and efficient. On the other hand, combining multi-dimensional factors such as battery safety risk, actual lighting demand, and laying density, the maintenance priority is dynamically adjusted to improve the utilization efficiency of street lights, avoid unnecessary resource waste, and enhance the adaptability of the maintenance work order to the actual application scenario.

[0054] Please refer to Figures 1 to 3 , Figure 1 which is a schematic diagram of an Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp and digital platform provided by an embodiment of the present invention; Figure 2 which is a schematic flowchart of another Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp and digital platform provided by an embodiment of the present invention; Figure 3It is a light source distribution diagram of a five-primary-color full-spectrum multi-color-temperature LED provided by an embodiment of the present invention.

[0055] As Figure 1 shown, an embodiment of the present invention provides a digital platform for an Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp. The digital platform includes: a plurality of Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamps 300 and a remote control center 400 that are communicatively connected;

[0056] Among them, each Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp 300 includes a lighting module 301, a power storage module 302, a public power module 303, and an Internet of Things controller 304;

[0057] The lighting module 301 is used to generate light based on current;

[0058] The public power module 303 is used to obtain power supply from the public power grid. The public power module 303 further includes a first power supply interface corresponding to the public power grid, and the first power supply interface is used to supply power to the lighting module 301 and / or the power storage module 302 during a first time period;

[0059] The power storage module 302 is used to obtain and store electric energy through the first power supply interface during the first time period. The power storage module 302 includes a second power supply interface, and the second power supply interface is used to supply power to the lighting module 301 during a second time period;

[0060] The Internet of Things controller 304 communicates with the remote control center 400 to implement the steps of the control method for the Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp provided in any embodiment of the present invention.

[0061] Among them, the Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp (hereinafter referred to as "intelligent street lamp") means that the intelligent street lamp 300 in the embodiment of the present invention can be based on Internet of Things communication, and the lighting module 301 of the intelligent street lamp 300 uses a combination of five-primary-color (white, green, yellow, blue, red) LED chips, can provide different color temperatures from warm white to cold white, and supports full-spectrum output and simulates natural sunlight.

[0062] Among them, the Internet of Things controller 304 further includes an Internet of Things communication module. The Internet of Things communication module is a key component for realizing device networking and remote management, enabling the controller to perform data exchange with other devices and the remote control center 400. The specific type can be a wired network (such as Ethernet), a wireless network (such as Wi-Fi, 4G / 5G, LoRa, Zigbee, etc.) or a hybrid network.

[0063] Exemplarily, asFigure 2 As shown, a number of interconnected Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamps 300 can communicate with a remote control center 400 through an Internet of Things controller 304. On this basis, the Internet of Things controller 304 and the remote control center 400 are linked to implement the steps of the control method of the Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamp provided in any embodiment of the present invention. In addition, a number of interconnected Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamps 300 can also communicate directly through the Internet of Things controller 304.

[0064] Exemplarily, as Figure 3 shown, the five-primary-color full-spectrum multi-color-temperature LED includes a substrate 3031; two single-primary-color light-emitting units on the central axis in the width direction of the substrate 3031, and multi-primary-color light-emitting unit matrices respectively arranged on both sides of the central axis in the width direction of the substrate. Each column of the multi-primary-color light-emitting unit matrix includes single-primary-color light-emitting units of two primary colors. The single-primary-color light-emitting unit is any one of white, green, yellow, blue, and red primary-color light-emitting units, and any two primary-color light-emitting units among red, blue, and green are not adjacent.

[0065] Furthermore, a lens 3012 is correspondingly arranged for each single-primary-color light-emitting unit; when the full-spectrum light source is connected to a power supply, the light emitted by the single-primary-color light-emitting unit enters from the incident surface of the lens 3012, is transmitted through the lens 3012 and exits from the exit surface of the lens, and is mixed with the light emitted by other single-primary-color light-emitting units after exiting from the exit surface of the corresponding lens 3012 in a specific area to obtain full-spectrum white light with greater light intensity on both sides than at the center and retaining the independent spectrum of each primary color. The corresponding primary-color light-emitting branch of the full-spectrum multi-color-temperature light source can be adjusted to turn on or off through a corresponding adjustment circuit, so that the current value corresponding to each primary-color light-emitting branch can be regulated according to different road sections to adjust the color temperature of the full-spectrum multi-color-temperature light source, and thus adapt to the different color temperature requirements of different road sections, or adjust the brightness of the full-spectrum multi-color-temperature light source to adapt to the different brightness requirements of different road sections.

[0066] Among them, the electricity storage module 302, also known as the energy storage module, is a device for storing electrical energy and releasing electrical energy when needed, used to balance the power grid load and achieve peak-shifting power consumption. The electricity storage module 302 can include a battery pack, a battery management system, a power converter, a communication interface, etc. The battery types of the battery pack include but are not limited to lithium-ion batteries, lead-acid batteries, sodium-sulfur batteries, etc. Specifically, a suitable type can be selected according to the application requirements of the street lamp, such as factors like energy density, power output, cycle life, and cost.

[0067] In some embodiments, the electricity storage module is not only used to supply power to the lighting module, but also can be used to supply power to other modules inside the smart street lamp that require power drive, so that the normal operation of the smart street lamp in the second period completely depends on the electricity storage module without using the mains power provided by the public power grid.

[0068] Peak-shaving energy storage can be achieved by adding an electricity storage module to the street lamp. Specifically, it means charging the electricity storage module at night when the electricity price is low and / or the power supply is stable; and using the stored energy to supply power during the day when the electricity price is high and it is the peak electricity consumption period, thereby reducing the pressure on the power grid and electricity bills and providing a stable power supply for the street lamp. Especially in cities implementing time-of-use electricity price policies, it can significantly reduce the operating cost. In addition, the battery can also be used as a backup power source to ensure that road lighting does not interrupt in case of power outages and other emergencies, improving the level of public safety.

[0069] Exemplarily, as Figure 1 shown, the smart street lamp 300 may further include a driving module 305, and the driving module 305 has a power conversion function to realize the switching of the power supply interface of the lighting module 301 in the first period and the second period, and provide a stable current for the lighting module 301.

[0070] Exemplarily, the lighting module 301 includes a five-primary-color full-spectrum multi-color-temperature LED; the public power module 303 includes a driving power supply for converting the mains power (alternating current) provided by the public power grid into direct current suitable for the LED to work and ensuring the stability of the output voltage or current.

[0071] As Figure 1 shown, in the first period, the mains power supplied by the public power grid is obtained through the driving power supply of the public power module 303. On the one hand, power is supplied to the lighting module 301 through the Internet of Things controller 304 based on the first power supply interface. On the other hand, power is supplied to the electricity storage module 302 through the Internet of Things controller 304 based on the first power supply interface to complete the electrical energy storage of the electricity storage module 302; in the second period, the electricity storage module 302 supplies power to the lighting module 301 through the driving module 305 based on the second power supply interface.

[0072] In order to further improve the economic benefits and practicability brought by the hybrid power supply mode, the embodiment of the present invention proposes a centralized maintenance method for a peak-shaving energy storage street lamp that takes into account the maintenance labor cost and electricity price cost, and specifically provides an Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shaving energy storage smart street lamp and its control method.

[0073] Among them, the smart street lamp includes a lighting module, a first power supply interface corresponding to the public power grid, an electricity storage module, and a second power supply interface corresponding to the electricity storage module. The first power supply interface is used to supply power to the lighting module and / or the electricity storage module in the first period, and the second power supply interface is used to supply power to the lighting module in the second period. Please refer toFigure 4 , Figure 4 is a schematic flowchart of a control method for an Internet of Things five - primary - color full - spectrum multi - color - temperature LED peak - shifting energy - storage intelligent street lamp provided by an embodiment of the present invention. As Figure 4 shown, the method includes steps S101 to S105.

[0074] When charging the energy - storage module at the first power - supply interface, monitor the charged power of the first power - supply interface and the stored power of the energy - storage module; calculate the first loss rate of the energy - storage module according to the charged power and the stored power.

[0075] Among them, the battery of the energy - storage module will gradually suffer losses during use. The aging or attenuation of the battery is an inevitable natural process. Correspondingly, the ratio of the current capacity of the battery to its standard capacity (i.e., the maximum capacity when it is a new battery) can be calculated to identify the energy - storage module with degraded performance, and then understand the health status of the energy - storage module. For example, use a data acquisition card and the LabVIEW software platform to monitor the charging and discharging process of the storage battery in real time to determine the loss rate of the energy - storage module.

[0076] When it is detected that the first loss rate of the energy - storage module is higher than the first preset value, mark the corresponding first street lamp as an inefficient street lamp.

[0077] Among them, the first preset value is used to evaluate the necessity of repairing the energy - storage module. The specific threshold can be flexibly set according to actual needs and is not limited here. It should be understood that the setting of the first preset value needs to comprehensively consider the characteristics of various battery types. When the loss rate is lower than the first preset value, it has little impact on the normal operation of the street lamp, allowing a certain degree of capacity loss without immediately triggering maintenance, resulting in lower additional motor costs, so as to avoid unnecessary maintenance costs and resource waste.

[0078] For example, when the battery capacity drops to 70% - 60% of the original capacity, the energy - storage ability of the battery is significantly reduced, the efficiency of the street lamp drops, and there may also be potential safety risks for the battery. Therefore, the first preset value is set to 30% - 40%. When the loss rate is higher than the first preset value, an overhaul signal for the energy - storage module can be triggered.

[0079] Determine the cost - benefit index of each planning area according to the additional electricity - price cost corresponding to the inefficient street lamps in each planning area and the maintenance operation cost of the planning area.

[0080] Among them, the planning area is determined in advance according to geographical location and the number of street lamps. For example, geographical division is carried out according to the distribution of intelligent street lamps, and at the same time, the number and distribution density of street lamps in each area are considered to ensure that the workload in each area is roughly balanced, forming several relatively independent planning areas.

[0081] Among them, the additional electricity price cost refers to the electricity cost corresponding to the additional use of commercial power by the street lamp due to the performance degradation of the electricity storage module (increase in the depreciation rate). For example, the electricity storage capacity of the electricity storage module with normal performance can supply the smart street lamp for 5 hours. Due to the lower electricity storage capacity of the electricity storage module, it can only supply the smart street lamp for 4 hours. At this time, 1 hour of commercial power needs to be additionally used to supply the smart street lamp, and the corresponding electricity cost generated is the additional electricity price cost. Another example is to calculate the electricity cost difference between normal street lamps and inefficient street lamps in the same area as the additional electricity price cost. Another example is to count the number of inefficient street lamps and estimate the additional electricity price cost based on the first depreciation rate and the number of inefficient street lamps.

[0082] Among them, the maintenance operation cost is the labor cost, consumable cost, equipment cost, operation cost, etc. required during maintenance, and may also include transportation costs (such as vehicle rental, fuel cost) and accommodation costs generated by dispatching teams to different locations for maintenance. The maintenance operation costs corresponding to different planning areas may be different. For example, the maintenance operation costs in remote areas are often much higher than those in other areas. The maintenance operation costs may also vary with time. For example, the maintenance operation costs in winter in the same area are higher than those in spring.

[0083] Please refer to Figures 5 to 6 , Figure 5 which is the on-site operation diagram of street lamp maintenance provided by the embodiment of the present invention; Figure 6 which is the on-site operation diagram of street lamp maintenance provided by the embodiment of the present invention. As Figures 5 to 6 shown, the maintenance operation of street lamps not only requires a large amount of manpower for on-site evaluation, fault diagnosis and actual maintenance work, but also requires the use of special equipment such as aerial work platforms and cleaning equipment. Therefore, centralized maintenance can greatly save maintenance operations. These costs can be estimated based on information such as historical data, market conditions, industry standards, and the distance of the planning area.

[0084] Among them, the cost-benefit index is an index used to measure the relationship between cost and benefit. The cost-benefit index can specifically be the cost savings rate, return on investment, etc. For example, taking the maintenance operation cost as the actual cost and the additional electricity price cost that may be saved after maintenance as the expected benefit, and at the same time involving more complex financial models and more data, such as factors that may affect the final cost-benefit analysis results, such as the service life, maintenance frequency, and failure rate of street lamps.

[0085] S104 Obtain the daily maintenance work order, which is used to record the maintenance time for each planned area; determine the maintenance priorities among several planned areas according to the cost-benefit indicators of each planned area, and adjust the maintenance time of each planned area based on the maintenance priorities to obtain the target maintenance work order. Among them, the daily maintenance work order includes but is not limited to the expected maintenance schedule, the numbers of street lights to be maintained, the maintenance workers, and the resources required for maintenance operations (such as tools, spare parts, and manpower).

[0086] S105 Perform maintenance on the inefficient street lights in several planned areas respectively according to the target maintenance work order. Among them, the maintenance includes but is not limited to operations such as replacing or repairing damaged components, software updating, and parameter adjustment to restore the best working state of the street lights.

[0087] Specifically, when charging the energy storage module using the mains power, the charging power input to the first power supply interface and the actual stored power of the energy storage module are monitored in real time, and then the first loss rate of the energy storage module is calculated. By regularly monitoring and analyzing the loss situation of the energy storage module, understanding the health status of the energy storage module, identifying the trend of performance degradation, and taking corresponding preventive measures to extend its service life, it helps to reduce the occurrence frequency of sudden failures, avoid the large-scale replacement requirements caused by battery aging, and thus significantly reduce the long-term maintenance cost.

[0088] When it is detected that the first loss rate of the energy storage module is higher than the first preset value, the corresponding street light is marked as an inefficient street light to quickly locate the street lights that need to be focused on in the follow-up. Count the number of street lights marked as inefficient in each planned area, calculate the additional electricity price cost caused by the inefficient street lights and the maintenance operation cost corresponding to this planned area, and then determine the cost-benefit indicator of each planned area to quantify the economic impact of the performance degradation of the batteries in different areas. According to the cost-benefit indicators of each planned area, re-evaluate and determine the maintenance priorities among multiple planned areas, and the areas with higher urgency will be given higher priorities. Based on the new priority order, adjust the maintenance time arrangement of each planned area to generate an optimized target maintenance work order.

[0089] Thus, taking into account the maintenance cost and the electricity price cost, on the basis of maximizing the cost-benefit, optimize the maintenance schedule to ensure the best utilization of resources, avoid unnecessary repetitive labor or delay of key tasks, and perform street light maintenance in a concentrated manner according to the finally determined target maintenance work order by area, further reducing the maintenance cost and ensuring that the maintenance work is both efficient and economical.

[0090] In some embodiments, the method further includes: obtaining the basic usage data and historical maintenance data of street lights, training a cost optimization model based on the basic usage data and the historical maintenance data, where the cost optimization model is used to predict the optimal maintenance interval; based on the cost optimization model, calculating the optimal maintenance interval for each planned area according to the basic usage data and historical maintenance data of the street lights laid in each planned area; and generating the daily maintenance work order according to the optimal maintenance interval of each planned area.

[0091] Among them, the basic usage data is data related to the performance of smart street lights, including the basic information of street lights (such as model, power, installation date, etc.), operating status (such as daily lighting time, brightness change, etc.), and environmental factors (such as weather conditions, traffic flow, etc.).

[0092] Among them, the historical maintenance data is data related to the maintenance of several or several types of smart street lights, including all past maintenance records, such as the specific time of each maintenance, the reason for maintenance, the measures taken and the results, etc.

[0093] Using the above two types of data as input, a cost optimization model is trained through machine learning algorithms. The model will consider multiple factors, such as the impact of maintenance frequency on the lamp life, the difference in labor costs for maintenance at different time periods, the loss of service interruption caused by faults, etc., so as to reduce the maintenance cost on the premise of ensuring the reliability of smart street lights. Further, the trained cost optimization model can be used to predict the optimal maintenance interval for each planned area. Input the specific basic usage data and historical maintenance data of each area into the model to obtain the most suitable maintenance cycle suggestion, and thus generate a detailed daily maintenance work order.

[0094] It should be understood that the maintenance strategy is dynamically adjusted according to the actual usage situation, rather than relying on fixed or empirical time intervals. This can not only reduce unnecessary maintenance activities, lower the operation cost, but also improve the reliability of the system and user satisfaction. In addition, with the accumulation of more data, the model will be continuously improved and become more accurate and effective.

[0095] In some embodiments, by quantifying the power consumption and additional electricity price cost of inefficient street lights and comparing them with the maintenance operation cost, the cost-benefit index of each planned area is determined. The S103 includes: according to the first depreciation rate of each inefficient street light in the planned area, calculating the power consumption cost of each inefficient street light according to the first depreciation rate; calculating the additional electricity price cost according to the electricity price standard of the planned area and the power consumption cost of each inefficient street light; calculating the cost difference between the additional electricity price cost and the maintenance operation cost, and determining the cost-benefit index of each planned area according to the cost difference.

[0096] According to the first depreciation rate of each inefficient street lamp in the planned area, evaluate the efficiency loss of these street lamps during normal operation. For example, the shortened time of the battery-powered lighting duration, which corresponds to the additional duration of using mains power for lighting. Thus, calculate the actual power consumption of each inefficient street lamp using the first depreciation rate. Another example is that for a storage module with normal performance, the charged power and the stored power are almost equal (or the loss value is a small negligible fixed value). When the depreciation rate increases, the charged power is greater than the stored power, and the electricity cost corresponding to the difference between the two is the additional electricity price cost.

[0097] Specifically, according to the electricity price standard of the planned area (such as time-of-use electricity price, peak-valley electricity price, etc.) and the electricity consumption cost of each inefficient street lamp, calculate the additional electricity price cost, which is the additional electricity expense generated due to the low efficiency of the street lamps.

[0098] Furthermore, compare the additional electricity price cost with the maintenance operation cost to determine the cost difference. For example, the net cost after subtracting the maintenance operation cost from the additional electricity price cost, or the cost savings after subtracting the additional electricity price cost from the maintenance operation cost. If the additional electricity price cost is higher than the maintenance operation cost, it indicates that maintenance may be a more economical choice; otherwise, it may be more cost-effective to maintain the status quo. Another example is to calculate the ratio between the additional electricity price cost and the maintenance operation cost. If the ratio is less than 1, it indicates that maintenance may be a more economical choice; if the ratio is greater than 1, it may be more cost-effective to maintain the status quo.

[0099] Based on the cost difference, determine the cost-benefit index for each planned area to determine whether it is economically viable to carry out maintenance in a certain area. For example, pre-set a mapping table between the cost difference and the cost-benefit index, and determine the cost-benefit index according to the threshold range where the cost difference is located. For example, when the cost difference is the net cost after subtracting the maintenance operation cost from the additional electricity price cost, in the mapping table of the cost difference and the cost-benefit index, the first-level cost-benefit is 500 and above, the second-level cost-benefit index is (500, 300], the third-level benefit index is (300, 1], and the fourth-level benefit index is less than 1. When the cost difference is 700 yuan, the corresponding cost-benefit index is the third-level index.

[0100] Thereby optimizing resource allocation, it can also ensure the effective utilization of funds and manpower, while improving the overall operation efficiency of the urban lighting system. In addition, through continuous monitoring and adjustment, the accuracy of cost-benefit analysis can be further improved, making the maintenance plan more scientific and reasonable. For example, if the cost-benefit index of a certain planned area shows a positive result (i.e., the long-term savings after maintenance exceed the maintenance cost), then maintenance can be prioritized in this area; otherwise, if the cost-benefit index is not ideal, the maintenance can be postponed and the timing of maintenance can be re-evaluated.

[0101] Furthermore, multi-level maintenance levels are set based on cost-benefit to provide a clear framework for evaluating and comparing the maintenance requirements of different regions or projects, so as to reasonably arrange the maintenance work schedule and make the maintenance work more planned and targeted.

[0102] In some embodiments, the maintenance priority includes a first maintenance level; the S104 includes: when the cost-benefit index is greater than the first cost index, setting the corresponding first planning area to the first maintenance level and adjusting the maintenance time of the first planning area to the first time threshold.

[0103] Specifically, the first maintenance level is priority maintenance. When the cost-benefit difference of a certain planning area is large, it indicates that timely maintenance can reduce the comprehensive cost, and the maintenance work should be arranged as soon as possible to prevent potential problems from evolving into larger failures and causing higher economic losses.

[0104] In some embodiments, the maintenance priority further includes a second maintenance level, and the planning areas of the first maintenance level are preferentially maintained compared to the planning areas of the second maintenance level; the S104 includes: when the cost-benefit index is less than the first cost index and greater than the second cost index, setting the corresponding second planning area to the second maintenance level and adjusting the maintenance time of the second planning area to the second time threshold; wherein, the first time threshold is earlier than the second time threshold.

[0105] Specifically, the second maintenance level is deferred maintenance. If the cost-benefit difference is small, the current maintenance will not bring obvious cost savings and may even lead to unnecessary expenses. Therefore, the maintenance time is appropriately postponed and the areas with small cost-benefit differences are maintained first.

[0106] Among them, the first cost index is greater than the second cost index. From the perspective of cost, the time urgency of maintenance for each maintenance area is divided. The corresponding first cost index is used to identify the planning areas with urgent maintenance tasks, and the second cost index is used to identify the planning areas with relatively ample maintenance task time. Based on the foregoing example, the first cost index can be the minimum value of 100 corresponding to the first-level cost-benefit and the second-level cost index, and the second cost index can be the minimum value of 1 of the third-level cost-benefit.

[0107] Specifically, the first cost index is used to identify the scenario where the additional electricity price cost is greater than the maintenance operation cost and the absolute value of the corresponding cost difference is large, and the second cost index is used to identify the scenario where the additional electricity price cost is greater than the maintenance operation cost, or the additional electricity price cost is less than the maintenance operation cost and the absolute value of the corresponding cost difference is small. Among them, the specific values of the first cost index and the second cost index can be flexibly set according to the actual situation.

[0108] Correspondingly, a first time threshold and a second time threshold are set. The specific thresholds can also be flexibly determined according to the maintenance equipment situation, maintenance manpower situation, first cost index, second cost index, etc. For example, the first time threshold is 5 days and the second time threshold is 20 days. When the maintenance time is adjusted to the second time threshold, the inspection of this area needs to be completed within 20 days. Another example is that if the second cost index is set relatively low, the planned area is more likely to be identified as the second planned area, and the second time threshold can be set to 30 days.

[0109] In some embodiments, the maintenance priority level includes a third maintenance level; the S104 includes: when the cost-benefit index is less than the second cost index, setting the corresponding third planned area to the third maintenance level, and the third planned area is maintained according to the maintenance time corresponding to the daily maintenance work order.

[0110] Specifically, the third maintenance level is daily maintenance. For those areas that have not shown obvious inefficiency but still need to maintain a normal operating state, they are classified as the daily maintenance level. This type of maintenance usually has a longer cycle to ensure the safety and reliability of all facilities.

[0111] It should be understood that especially for remote areas, the maintenance cost is often much higher than the possible electricity savings, and in a cost-benefit-based evaluation system, it is often difficult for remote areas to meet the maintenance standards. Therefore, they are specially treated as routine maintenance to avoid over-investment while ensuring safety. For example, the best maintenance interval for the planned area corresponding to a remote area is 6 months. As time goes by, the maintenance time of this planned area will enter the first time threshold, and the maintenance personnel will arrange maintenance to complete the maintenance task within the first time threshold (such as 5 days).

[0112] In some embodiments, the method further includes: after any of the planned areas is maintained, generating the next maintenance time according to the best maintenance interval corresponding to the planned area and writing it into the daily maintenance work order. Thus, the next maintenance time is automatically planned after the maintenance is completed, ensuring that all planned areas can receive appropriate attention according to their specific needs and avoiding repeated maintenance.

[0113] It should be understood that the maintenance tasks in the embodiments of the present invention include but are not limited to the following two types: routine maintenance and fault maintenance. Routine maintenance is an automatic preventive measure aimed at reducing the probability of faults, while post-fault maintenance is a passive countermeasure aimed at solving the faults that have occurred. Both are indispensable parts of street lamp maintenance, helping to ensure the reliability and safety of the street lamp system.

[0114] Among them, the workload and complexity of routine maintenance are relatively low, which may include preventive measures such as cleaning, tightening, checking the battery and circuit of some street lights. The workload and complexity of fault maintenance are relatively high, and fault diagnosis is required, which may involve more complex maintenance work, such as replacing damaged components (such as batteries) and repairing circuits. Routine maintenance can be carried out incidentally during fault maintenance and can be flexibly adjusted according to the actual situation. Routine maintenance does not mean that all street lights in the area need to be repaired. Street lights that are operating normally can be omitted, and necessary maintenance can be carried out on those with certain defects, such as street lights with a first depreciation rate higher than the third preset value and lower than the first preset value. In the long run, this strategy can bring significant cost savings.

[0115] The third preset value is used to evaluate the maintainability of the energy storage module, and the specific threshold can be flexibly set according to actual needs, such as 10%, which is not limited here. When the depreciation rate is higher than the third preset value and lower than the first preset value, the impact on the normal operation of the street light can be ignored, and the additional motor cost caused is extremely low. Conducting maintenance on it incidentally can prevent the depreciation rate from increasing further.

[0116] Furthermore, when the gap between the optimal maintenance interval and the actual maintenance interval in the planned area is too large, batch maintenance can be triggered based on this data support. Batch maintenance is based on the production batches of the street lights in the planned area, and spot checks are carried out on the street light components of the same batch to determine whether there are product component defects, and corresponding preventive measures are taken. For example, when the optimal maintenance interval in the planned area is half a year, but in actual application, due to inefficient or faulty street lights, the maintenance priority is frequently adjusted, resulting in an actual maintenance interval of 2 months. It can be identified that there may be serious defects in a certain batch of components of the smart street lights, such as component quality, supplier reliability, etc. Once supply chain problems are found, preventive measures can be taken, such as changing suppliers, improving component quality, or optimizing inventory management, to further reduce long-term maintenance costs.

[0117] In some embodiments, the method further includes: when the first depreciation rate is higher than the second preset value, marking the corresponding first street light as a faulty street light, where the second preset value is higher than the first preset value; updating the fourth planned area where the faulty street light is located to the first maintenance priority, and adjusting the maintenance time of the fourth planned area to the first time threshold.

[0118] Specifically, when it is monitored that the first depreciation rate of the smart street light is higher than the second preset value, the smart street light is identified as a faulty street light with a safety risk, and the maintenance priority and time arrangement are updated to provide a more timely maintenance plan.

[0119] In some embodiments, the present invention provides another centralized maintenance method for peak-shifting energy storage street lamps that ensures the safety and utilization rate of facilities on the basis of comprehensive cost optimization, further improving the practicability of peak-shifting energy storage street lamps, and specifically provides another control method for Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamps. Among them, the intelligent street lamp includes a lighting module, a first power supply interface corresponding to the public power grid, a power storage module, and a second power supply interface corresponding to the power storage module. The first power supply interface is used to supply power to the lighting module and / or the power storage module during a first time period, and the second power supply interface is used to supply power to the lighting module during a second time period.

[0120] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of another control method for Internet of Things five-primary-color full-spectrum multi-color-temperature LED peak-shifting energy storage intelligent street lamps provided by an embodiment of the present invention. As Figure 7 shown, the method includes steps S201 to S207. The method includes:

[0121] S201 According to a first time interval, when charging the power storage module at the first power supply interface, monitor the charging power input to the first power supply interface and the power stored in the power storage module; calculate a first loss rate of the power storage module according to the charging power and the stored power;

[0122] S202 When it is detected that the first loss rate of the power storage module is higher than a first preset value, mark the corresponding first street lamp as an inefficient street lamp;

[0123] S203 Determine the cost-benefit index of each planning area according to the additional electricity price cost corresponding to the inefficient street lamps in each planning area and the maintenance operation cost of the planning area;

[0124] S204 Obtain a daily maintenance work order, which is used to record the maintenance time for each planning area; according to the cost-benefit index of each planning area, determine the maintenance priority among several planning areas, and adjust the maintenance time of each planning area based on the maintenance priority to obtain a target maintenance work order;

[0125] S205 Perform maintenance on the inefficient street lamps in several planning areas respectively according to the target maintenance work order;

[0126] When it is determined in step S202 that the first loss rate is higher than the first preset value, the following steps are further included: S206 update the first time interval corresponding to the inefficient street lamp to a second time interval, where the second time interval is less than the first time interval; and based on the second time interval, calculate the second loss rate of the energy storage module when charging the energy storage module at the second power supply interface; update the label of the first street lamp according to the second loss rate; S207 update the statistics of the inefficient street lamps in each planned area.

[0127] Specifically, by monitoring the loss rate of the energy storage module to evaluate the battery performance, the fault risk can be identified in advance, sudden faults and the need for large-scale street lamp replacement can be reduced, and the long-term maintenance cost can be lowered. And by comprehensively considering the additional electricity price and the maintenance operation cost to quantify the economic impact, the resource allocation and the maintenance schedule can be optimized, a three-level maintenance level is set, and the street lamps are maintained centrally by area to ensure efficient and economic maintenance work and achieve planned maintenance with cost reduction. For details, reference can be made to the description in the foregoing embodiments, which will not be elaborated here.

[0128] On this basis, a multi-level battery performance monitoring mechanism is proposed to achieve efficient, economic and safe operation of the street lamp system. Specifically, the first time interval is used for regular monitoring under normal circumstances, and the normal street lamps are monitored at an appropriate interval to ensure the normal operation of the equipment, while saving resources and reducing the unnecessary data processing burden; the second time interval is used for regular monitoring of inefficient street lamps. For the inefficient street lamps with deteriorated battery performance, the monitoring time interval is adjusted to a shorter second time interval to more frequently monitor the status of the inefficient street lamps and ensure the safe operation of the inefficient street lamps during the postponed maintenance period.

[0129] In some embodiments, when it is determined in step S202 that the first loss rate is higher than the first preset value, the following steps are further included: obtain at least two second street lamps in the planned area where the first street lamp is located; compare the loss rate difference between the first loss rate of the first street lamp and the first loss rate of the second street lamp. If the loss rate difference is greater than the preset difference, update the second time interval to a third time interval, where the third time interval is less than the second time interval; based on the third time interval, calculate the third loss rate of the energy storage module when charging the energy storage module at the second power supply interface; update the label of the first street lamp according to the third loss rate; update the statistics of the inefficient street lamps in each planned area.

[0130] Among them, the first street lamp is a smart street lamp whose loss rate needs to be evaluated for anomalies, and the second street lamp is a smart street lamp used to verify and compare whether the loss rate of the first street lamp is abnormal. The second street lamp is geographically close to the first street lamp, has a similar installation time and model, and a similar working load. The high correlation between the two makes the loss rates of the two comparable. Further, since street lamps are mostly installed in batches, there are often multiple associated second street lamps for the first street lamp, and at least two second street lamps can be randomly selected from them.

[0131] Among them, the third time interval is used for key high-frequency monitoring of batteries with abnormal risks.

[0132] Among them, the preset difference is flexibly determined according to the basic usage data of the street lamp. For example, the preset differences corresponding to street lamps of different models, different powers, and different working environments can be different to improve the accuracy of anomaly detection.

[0133] Specifically, when it is confirmed through comparison with the associated second street lamp that the loss rate of a certain inefficient street lamp is abnormal, the second time interval is updated to a shorter third time interval to promptly capture any signs of deterioration, further improving the sensitivity of the adjustment of the maintenance priority, and thus providing the adaptability of the maintenance work order.

[0134] In some embodiments, the maintenance priority includes a first maintenance level; the S204 includes: when the cost-benefit index is less than the first cost index, setting the corresponding first planning area to the first maintenance level and adjusting the maintenance time of the first planning area to the first time threshold. For details, reference can be made to the description in the foregoing embodiments and will not be elaborated here.

[0135] In some embodiments, the maintenance priority further includes a second maintenance level, and the planning area of the first maintenance level is preferentially maintained compared to the planning area of the second maintenance level; the S204 includes: when the cost-benefit index is greater than the first cost index and less than the second cost index, setting the corresponding second planning area to the second maintenance level and adjusting the maintenance time of the second planning area to the second time threshold; where the first time threshold is earlier than the second time threshold. For details, reference can be made to the description in the foregoing embodiments and will not be elaborated here.

[0136] In some embodiments, the method further includes: when the second loss rate is higher than the second preset value, and / or when the third loss rate is higher than the second preset value, marking the corresponding first street lamp as a faulty street lamp, where the second preset value is higher than the first preset value; updating the fourth planning area where the faulty street lamp is located to the first maintenance priority and adjusting the maintenance time of the fourth planning area to the first time threshold.

[0137] Among them, the second preset value is used to evaluate the urgency of maintenance of the electricity storage module, and the specific threshold can be flexibly set according to actual needs, such as 50%-60%, which is not limited here. It should be understood that the setting of the second preset value needs to comprehensively consider the characteristics of various battery types. When the depreciation rate is lower than the second preset value, the safety risk of the battery is relatively small, and it is allowed to allocate maintenance time by area according to the cost-benefit index. When the depreciation rate is higher than the second preset value, the safety risk of the battery is relatively large. For safety reasons, a quick response is required to ensure that faults are handled in a timely manner, reducing potential safety risks and operation interruptions.

[0138] Specifically, when the second depreciation rate is higher than the second preset value, the depreciation rate of the electricity storage module is too high. In addition, when the third depreciation rate is higher than the second preset value, the electricity storage module may have an abnormal performance degradation trend, and this trend develops rapidly. This situation implies potential safety risks, such as battery overheating, short circuit, etc., which may cause street lights to malfunction and not illuminate, or even lead to greater safety hazards. Therefore, the planning area where the faulty street light is located is preferentially repaired, and the maintenance work order is updated accordingly to improve the adaptability and accuracy of the maintenance work order.

[0139] In some embodiments, the method further includes: when the second depreciation rate continuously is lower than the first preset value, and / or when the third depreciation rate continuously is lower than the first preset value, monitoring the actual lighting time of the electricity storage module; if the actual lighting duration is greater than or equal to the preset qualified duration, marking the corresponding first street light as a normal street light.

[0140] Specifically, when the depreciation rate continuously is higher than the first preset value, by monitoring the actual lighting time, if the duration is qualified, it is considered that although the electricity storage module has a certain depreciation rate, it can still meet the basic lighting requirements, or the first depreciation rate monitoring is abnormal, and the street light is updated to a normal street light, and the maintenance work order is updated accordingly to further improve the adaptability and accuracy of the maintenance work order.

[0141] In some embodiments, the method further includes: calculating the actual laying density of each planning area according to the number of inefficient street lights in the planning area and the area of the planning area; when the actual laying density of each planning area is less than the preset density value, updating the corresponding fifth planning area to the first maintenance level and adjusting the maintenance time of the fifth planning area to the first time threshold.

[0142] Specifically, the number of normal street lights is calculated through the number of inefficient street lights, and the actual laying density of the planning area is calculated in combination with the area of the planning area, thereby identifying those fifth planning areas with sparse street light distribution and low utilization rate, so as to improve the maintenance priority of these areas, advance the maintenance time of these areas, and then optimize the resource allocation of these areas to avoid waste of resources.

[0143] In some embodiments, the method further includes: after any of the planned areas is repaired, generating the next repair time according to the optimal repair interval corresponding to the planned area and writing it into the daily repair work order. For specific details, reference may be made to the descriptions in the foregoing embodiments, which will not be elaborated herein.

[0144] It should be understood that the street lights in a general planned area are all installed in the same batch. When the overall number of low-efficiency street lights is low, the possibility of a faulty street light occurring is low; on the other hand, since a street light with a first depreciation rate higher than the first preset value is marked as a low-efficiency street light, when the number of low-efficiency street lights reaches a certain amount, the change in the cost-benefit index will trigger a fault repair. Even if the area is of the second repair level, there may be a short repair waiting period, but in the short term, the possibility of the depreciation rate rising to the second preset value is low, that is, the possibility of a faulty street light occurring is low; further, during the fault repair, the routine repair is carried out incidentally, and this combined repair strategy also reduces the possibility of a faulty street light occurring. Therefore, not only the maintenance cost is reduced in the long run, but also the sudden situation of a faulty street light is compressed to a very low probability, reducing potential safety risks and operation interruptions, while reducing the repair difficulty and cost.

[0145] Meanwhile, a repair strategy based on cost-benefit analysis and multi-dimensional adjustment is provided. By combining multi-dimensional factors such as battery safety risks, actual lighting requirements, and laying density, the repair priority is dynamically adjusted, improving the usage efficiency and safety of street lights, avoiding unnecessary resource waste, enhancing the adaptability of the repair work order to the actual application scenario, and thus improving the practicality of the peak-shifting energy storage street lights. At the same time, combined with the multi-level battery performance monitoring mechanism and the combined repair strategy in the embodiments of the present invention, the occurrence of such sudden adjustments is reduced, making the time arrangement of the repair work order a stable adjustment, and the repair work order sets a time node for the repair task in advance. The staff can plan in advance to avoid task backlogs. Even in an emergency where the repair demand exceeds the plan or resource limitations, there is a buffer time to respond, ensuring the efficient operation and cost-benefit of the smart street lights.

[0146] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
