Description

Technical Field

[0001] The present invention relates to the technical field of street lamp control, and in particular to an intelligent dispatching system for controlling a DC power supply cabinet with a DC power supply. Background Art

[0002] At present, DC power supply control cabinets are widely used in urban public lighting systems, especially street lighting systems. With the acceleration of urbanization and the advancement of smart cities, traditional power supply cabinet systems have gradually exposed some limitations, especially in terms of energy efficiency, intelligent management and environmental adaptability. Many traditional systems lack real-time monitoring and automated management functions and rely on manual inspections and manual adjustments, which not only consumes human resources, but also makes it difficult to achieve accurate energy management.

[0003] At present, a Chinese patent application numbered CN201911021723.9 discloses a street light switch control method based on a distribution box, which relates to the field of street light control technology. The street light switch control method based on a distribution box includes the following steps: S1. Divide all street lights in the distribution box area, divide the street lights into three independent roads, and establish a control relationship between the branches and the distribution box; S2. Establish a power connection relationship between the distribution boxes, so that each distribution box can control the transmission of power from other distribution boxes; S3. Control the switch of the street light according to the intensity of sunlight, and control the closing of the branches according to the time period; S4. Timely match the optimal distribution box nearby, establish a power transmission channel, restore the power supply of the street light and record the power value. Although the above technology can divide all street lights into three roads, the distribution box can independently control the switch of the three-way street lights according to the actual situation, so that all street lights do not need to be turned on all night, and the on and off of the street light power is reasonably controlled, which greatly reduces the waste of power resources to a certain extent, but it is impossible to allocate different voltage ratios according to different areas and traffic volume, resulting in waste of power resources and affecting the working efficiency of the power supply box.

[0037] Figure 2 A voltage distribution ratio table of an intelligent dispatching system for controlling a DC power supply cabinet is provided in accordance with an embodiment of the present invention. DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments.

[0039] Example 1, reference Figure 1 , provides an intelligent dispatching system for controlling a DC power supply cabinet with a DC power supply, including a region division module, a region allocation module, a flow collection module, a flow allocation module and a comprehensive output module:

[0040] The area division module is used to collect the coordinates of the location of street lamps, and divide the areas into high priority areas, medium priority areas and low priority areas according to the coordinates of the location of street lamps and Internet maps.

[0041] By obtaining the geographic coordinates of street lights and combining them with Internet maps and landmark type analysis, street lights can be divided into high-priority areas, medium-priority areas, and low-priority areas, which will help to optimize the allocation of power resources according to the lighting needs of different areas.

[0042] The regional allocation module is used to formulate regional voltage allocation strategies according to high priority areas, medium priority areas and low priority areas, and set regional voltage allocation ratio thresholds for high priority areas, medium priority areas and low priority areas.

[0043] Voltage allocation strategies are formulated for areas of different priorities to ensure that high-priority areas have sufficient power supply, while reasonably limiting power consumption in medium-priority and low-priority areas. By setting regional voltage allocation ratio thresholds, refined management and efficient utilization of power resources are achieved.

[0044] The traffic collection module is used to obtain the average traffic flow within a certain period of time based on historical traffic flow records, and divide the period into high traffic flow period, medium traffic flow period and low traffic flow period.

[0045] The average traffic flow for each hour is calculated based on historical traffic flow records, and the time period is divided into high traffic flow period, medium traffic flow period and low traffic flow period accordingly, providing a dynamic adjustment basis for subsequent voltage distribution based on real-time traffic flow.

[0046] The traffic distribution module is used to formulate traffic voltage distribution strategies according to high traffic flow periods, medium traffic flow periods and low traffic flow periods, and set the traffic voltage distribution ratio thresholds for high traffic flow periods, medium traffic flow periods and low traffic flow periods.

[0047] Voltage distribution strategies are formulated for different traffic flow periods to ensure that street lamps are adequately bright during high traffic flow periods. At the same time, the voltage is appropriately reduced during medium and low traffic flow periods to save energy. By setting the traffic voltage distribution ratio threshold, the flexibility and adjustability of voltage distribution are achieved.

[0048] The integrated output module is used to integrate the area allocation module and the flow allocation module to generate a voltage distribution working mechanism.

[0049] Integrate the results of regional allocation and flow distribution, formulate a voltage distribution ratio table, provide clear guidance for the voltage distribution of each street lamp in different time periods and areas, automatically find the voltage distribution ratio table according to the current street lamp's geographic coordinates and time period data, and output the current street lamp's voltage distribution ratio, thus realizing the automation and intelligence of voltage distribution and improving the system's response speed and accuracy.

[0050] The regional division module includes a geographic location acquisition unit and a regional setting division unit:

[0051] The geographic location acquisition unit is used to acquire the geographic coordinates of the street lamp according to the GPS and output the geographic coordinate data.

[0052] The geographical location coordinates of street lamps are accurately obtained through GPS technology, providing accurate basic data for subsequent regional division and ensuring the accuracy and reliability of regional division.

[0053] The area setting division unit is used to set high-priority areas, medium-priority areas and low-priority areas. The high-priority areas include medical facilities, main traffic arteries and transportation hubs, the medium-priority areas include commercial office areas, schools and residential main roads, and the low-priority areas include parks, green spaces, tourist attractions and secondary roads. According to the Internet map and geographic coordinate data, the landmark types within a certain distance of the location of the geographic coordinate data are collected, and the distance here is 1 kilometer. The landmark with the highest frequency among the landmark types is selected as the main landmark. According to the main landmark, street lamps are selected to be located in the high-priority area, medium-priority area or low-priority area. The high-priority area, medium-priority area and low-priority area respectively include the geographic coordinate data of all street lamps located in the corresponding area.

[0054] According to the preset regional priority rules, combined with the Internet map and the geographic coordinate data of the street lights, the street lights are intelligently divided into three priority areas: high priority area, medium priority area and low priority area. By analyzing the frequency of landmark types, the priority of each street light is accurately defined, realizing the intelligent and refined regional division, providing strong support for the formulation of subsequent voltage distribution strategies.

[0055] The regional allocation module includes a regional strategy formulation unit and a regional threshold setting unit:

[0056] The regional strategy formulation unit is used to formulate voltage allocation strategies for high priority areas, medium priority areas and low priority areas. In the same time period, the voltage allocation amount decreases step by step according to the high priority areas, medium priority areas and low priority areas.

[0057] According to the priority results of regional division, a reasonable voltage allocation strategy was formulated. In the same time period, the voltage allocation method of decreasing level by level ensures that the high-priority areas have sufficient power supply, while reasonably limiting the power consumption of the medium-priority and low-priority areas, thus achieving the optimal allocation and efficient use of power resources.

[0058] The regional threshold setting unit is used to set the regional voltage allocation ratio thresholds of the high priority area, the medium priority area and the low priority area, wherein the regional voltage allocation ratio threshold of the high priority area is a first ratio threshold, the regional voltage allocation ratio threshold of the medium priority area is a second ratio threshold, and the regional voltage allocation ratio threshold of the low priority area is a third ratio threshold.

[0059] The first ratio threshold is 100%-80%, the second ratio threshold is 90%-70%, and the third ratio threshold is 80%-60%.

[0060] Clear voltage distribution ratio thresholds are set for areas of different priority levels, providing quantitative standards and guidance for the actual distribution of voltage. By setting a reasonable ratio threshold range, the flexibility and adjustability of voltage distribution are ensured, while avoiding excessive waste or shortage of power resources and ensuring the stable operation of the street lighting system.

[0061] The traffic collection module includes a traffic calculation unit and a traffic division unit:

[0062] The traffic calculation unit is used to calculate the average traffic flow per hour based on historical traffic flow records. The historical traffic flow records include recording point coordinate data and corresponding traffic flow data, and the output is a traffic flow data group with time period labels and recording point coordinate data.

[0063] By processing historical traffic records, the average traffic flow per hour can be accurately calculated, and a traffic flow data set with time period labels and recording point coordinate data can be generated, providing a key basis for subsequent traffic division and voltage distribution, ensuring the accuracy and timeliness of traffic management.

[0064] The traffic division unit is used to find the time period in the traffic data group where the average traffic flow exceeds the first traffic flow value, which is set as the high traffic flow period; to find the time period in the traffic data group where the average traffic flow is from the second traffic flow value to the first traffic flow value, which is set as the medium traffic flow period; and to find the time period in the traffic data group where the average traffic flow is less than the second traffic flow value, which is set as the low traffic flow period.

[0065] The first traffic flow value is 1000 vehicles, and the second traffic flow value is 500 vehicles.

[0066] Based on the data provided by the traffic calculation unit, the time period can be intelligently divided into three traffic flow periods: high traffic flow period, medium traffic flow period and low traffic flow period. By setting clear traffic flow thresholds, time periods with different traffic flow levels can be automatically identified, providing an important reference for the formulation of voltage distribution strategies. This flexible division method helps to achieve dynamic adjustment and optimal allocation of power resources, and improve the energy efficiency and response speed of the street lighting system.

[0067] The traffic distribution module includes a traffic strategy formulation unit and a traffic threshold setting unit:

[0068] The traffic strategy formulation unit is used to formulate voltage allocation strategies for high traffic flow periods, medium traffic flow periods and low traffic flow periods. In the same area, the voltage allocation amount decreases step by step according to the high traffic flow periods, medium traffic flow periods and low traffic flow periods.

[0069] According to the different traffic flow periods, corresponding voltage distribution strategies have been formulated. In the same area, the voltage distribution method of decreasing step by step ensures that the brightness of street lamps is sufficient during high traffic flow periods to cope with higher lighting needs. At the same time, the voltage is appropriately reduced during medium and low traffic flow periods to save energy. The formulation of this strategy helps to achieve the rational allocation and efficient use of power resources and improve the overall efficiency of the street lighting system.

[0070] The flow threshold setting unit is used to set the flow voltage allocation ratio threshold for high traffic flow period, medium traffic flow period and low traffic flow period. The flow voltage allocation ratio threshold for high traffic flow period is the first ratio threshold, the flow voltage allocation ratio threshold for the medium priority area is the second ratio threshold, and the flow voltage allocation ratio threshold for the low traffic flow period is the third ratio threshold.

[0071] Clear voltage distribution ratio thresholds are set for different traffic flow periods. These thresholds provide quantitative standards and guidance for the actual voltage distribution. By setting reasonable ratio thresholds, the flexibility and adjustability of voltage distribution are ensured, so that voltage distribution can be dynamically adjusted with changes in traffic flow, thereby meeting the lighting needs of different periods and achieving the goal of energy conservation and emission reduction.

[0072] The comprehensive output module includes a ratio table formulation unit and a working mechanism establishment unit:

[0073] The ratio table formulation unit is used to integrate the regional allocation module and the flow allocation module, and formulate a voltage allocation ratio table according to the regional voltage allocation ratio threshold and the flow voltage allocation ratio threshold. The voltage allocation ratio table first fixes the high priority area, the medium priority area and the low priority area, and allocates the high traffic flow period, the medium traffic flow period and the low traffic flow period to the high priority area, the medium priority area and the low priority area according to the recorded point coordinate data in the traffic flow data group, and generates a voltage allocation ratio table. The voltage allocation ratio table refers to Figure 2 .

[0074] As the core component of the comprehensive output module, the proportion table formulation unit successfully integrates the output results of the regional allocation module and the flow allocation module. By comprehensively considering the regional voltage allocation proportion threshold and the flow voltage allocation proportion threshold, a detailed voltage allocation proportion table is formulated, which realizes the refinement and dynamicization of the voltage allocation strategy. The final generated voltage allocation proportion table provides direct and effective guidance for subsequent voltage distribution work.

[0075] The working mechanism establishing unit is used to formulate a voltage distribution working mechanism according to the voltage distribution ratio table, and the voltage distribution working mechanism outputs the voltage distribution ratio of the current street lamp according to the geographic coordinate data and time period data of the current street lamp.

[0076] The voltage distribution working mechanism of the working mechanism establishment unit is:

[0077] Collect the geographic coordinate data of the current street lamp, confirm whether the current street lamp is located in a high priority area, a medium priority area or a low priority area according to the geographic coordinate data of the current street lamp, and output the area result.

[0078] Input the regional results into the voltage distribution ratio table to find the corresponding regional voltage distribution ratio threshold.

[0079] Collect the time period data of the current street light, confirm whether the current street light is in a high traffic flow period, a medium traffic flow period, or a low traffic flow period based on the time period data of the current street light, and output the time period results.

[0080] Input the time period results into the voltage distribution ratio table to find the corresponding flow voltage distribution ratio threshold.

[0081] Confirm the distribution ratio value at the intersection of the corresponding regional voltage distribution ratio threshold and the flow voltage distribution ratio threshold, and output it as the voltage distribution ratio of the current street lamp.

[0082] The working mechanism establishment unit constructs a voltage distribution working mechanism based on the output of the ratio table formulation unit. It can collect the current street lamp's geographic coordinate data and time period data in real time, and quickly determine the area and time period where the street lamp is located through intelligent analysis. Based on this, it can find the corresponding voltage distribution ratio threshold from the voltage distribution ratio table. By comprehensively considering the information of the two dimensions of area and time period, it can accurately output the current street lamp's voltage distribution ratio. It not only realizes the automation and intelligence of voltage distribution, but also greatly improves the accuracy and flexibility of voltage distribution, providing strong support for the optimized operation of the street lamp lighting system.

[0083] By distributing voltage according to the areas where street lamps are located and the traffic flow periods, it is possible to effectively reduce power consumption in low-priority areas and low-traffic periods while ensuring lighting needs, thereby significantly reducing energy waste and achieving the goal of energy conservation and emission reduction. In high-priority areas and high-traffic periods, it can automatically increase voltage distribution to ensure the lighting brightness and stability of these key areas, improve road safety and the convenience of citizens' travel. The system uses GPS, Internet maps and historical traffic flow data to achieve intelligent management of street lamp power supply. Without manual intervention, it can automatically adjust voltage distribution based on real-time data and preset strategies, greatly reducing management costs and improving management efficiency. rate, through reasonable voltage distribution, while ensuring the lighting effect, reduce excessive wear and tear of street lamps, thereby extending the service life of street lamps and reducing replacement and maintenance costs. According to the actual conditions of different cities and regions, the regional division and voltage distribution strategies can be flexibly adjusted. At the same time, with the accumulation of historical traffic data, the distribution strategy can be continuously optimized and the scheduling accuracy can be improved. Through intelligent and refined street light management, a safer, more comfortable and beautiful night environment can be created for the city, which will enhance the overall image of the city and the quality of life of residents. It not only helps to save energy and reduce emissions, but also embodies the concept of smart city construction and has made positive contributions to promoting the sustainable development of cities.
