Description

Technical Field

[0001] The present invention belongs to the field of street lamp energy-saving management and control, and relates to data analysis technology, and specifically is a park road street lamp energy-saving management and control system based on data analysis. Background Art

[0002] The street lamp energy-saving control system is a system used for street lamp energy-saving control. The system is mainly composed of digital control voltage stabilization technology and programmable energy-saving control system. The regulation method is to adjust the output power by adjusting the electronic switch matrix of the digital control voltage stabilizer of the energy-saving control system and adjusting the TAP of the transformer; The Park Road Street Light Energy Saving Management System is a system that integrates a variety of advanced technologies and equipment. It aims to optimize the use efficiency of street lights and reduce energy consumption through intelligent control and energy-saving management, while improving lighting effects and maintenance efficiency.

[0003] The invention patent with announcement number CN102196616B discloses a traffic-sensing energy-saving street lamp and an energy-saving street lamp system. The energy-saving street lamp system includes an adjacent street lamp control system. A first traffic-sensing energy-saving street lamp is adjacent to a second traffic-sensing energy-saving street lamp. The adjacent street lamp control system controls the second traffic-sensing energy-saving street lamp to turn on and delays the on state. The first traffic-sensing energy-saving street lamp is no longer delayed again to achieve energy saving and humanized control. However, the energy-saving street lamp system needs to allocate a set of corresponding element components to each traffic-sensing lamp. Although the lamp can be adaptively controlled according to the sensing results, the corresponding sensing elements need to be continuously powered on for scene monitoring. This results in the energy saved by the intelligent control of the lamp being consumed by the power consumption of the element components, and the actual energy saving level is not high.

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0006] The purpose of the present invention can be achieved through the following technical solutions: A park road lamp energy-saving control system based on data analysis, including an energy-saving control platform, wherein the energy-saving control platform is communicatively connected with a regional division module, a control analysis module, a management optimization module and a regional evaluation module; The area division module is used to perform segmentation processing on the park: randomly select a segmentation method to divide the park's public lighting area into several sub-areas, and the segmentation methods include road segmentation, center segmentation, and matrix segmentation; mark the street lamps set in the sub-area as the control equipment group of the sub-area, allocate monitoring equipment groups to the sub-areas, and allocate operating time periods to the monitoring equipment groups; randomly allocate monitoring components in the monitoring equipment groups to the street lamp racks in the control equipment groups of the sub-areas; The control and analysis module is used to perform energy-saving control and analysis on the street lamps in the park road: generate a monitoring cycle with a duration of L1 natural days, and analyze whether the sub-area is in a traffic scene through the monitoring components of the monitoring device group during the operation period within the monitoring cycle: if so, all street lamps in the control device group of the sub-area are controlled by the controller to light up for L2 minutes, and all street lamps in the control device group are controlled to turn off after L2 minutes; if not, no processing is performed; The regional assessment module is used to assess and analyze the rationality of regional division of the park; The management optimization module is used to perform management optimization analysis on the park road street lights.

[0007] Furthermore, the specific process of the regional assessment module evaluating and analyzing the rationality of the regional division of the park includes: at the end of the monitoring period, obtaining the number of times the control device group lights up during the monitoring period and marking it as the start and close control value of the control device group, calculating the variance of the start and close control values ​​of all control device groups during the monitoring period to obtain the control deviation coefficient, and judging whether the rationality of the regional division of the monitoring period meets the requirements through the control deviation coefficient.

[0008] Furthermore, the specific process of determining whether the rationality of the regional division of the monitoring period meets the requirements includes: comparing the control deviation coefficient with the preset control deviation threshold: if the control deviation coefficient is less than the control deviation threshold, then it is determined that the rationality of the regional division of the monitoring period meets the requirements; if the control deviation coefficient is greater than or equal to the control deviation threshold, then it is determined that the rationality of the regional division of the monitoring period does not meet the requirements, and other division methods are used to re-divide the sub-areas of the park at the beginning of the next monitoring period.

[0009] Furthermore, the specific process of the management optimization module performing management optimization analysis on the park road street lights includes: arranging the control equipment groups in descending order of the opening and closing control value values ​​to obtain a control sequence, marking the first L3 control equipment groups and the last L3 control equipment groups in the control sequence as expansion equipment groups and reduction equipment groups respectively, and performing control reorganization analysis on the expansion equipment group and the reduction equipment group at the beginning of the next monitoring cycle.

[0010] Furthermore, the specific process of conducting management and control reorganization analysis on the expanded equipment group and the reduced equipment group includes: assigning the street lights at the adjacent edges of the sub-areas of the expanded equipment group into the expanded equipment group, and assigning the street lights at the edges of the reduced equipment group into the adjacent managed equipment group; if the sub-areas corresponding to the two expanded equipment groups are adjacent, the expanded equipment groups in the two adjacent sub-areas share the control rights of the street lights at the junction.

[0011] Furthermore, the process of conducting control and reorganization analysis on the expanded equipment group and the reduced equipment group also includes: marking the L2 minutes that the controlled equipment group is on during the monitoring period as the control period, marking the interval duration between any two adjacent control periods as the interval value, summing up all interval values ​​of the controlled equipment group during the monitoring period and taking the average value to obtain the interval coefficient, and comparing the interval coefficient with the preset interval threshold: if the interval coefficient is less than the interval threshold, it is determined that the controlled equipment group has a continuous feature during the monitoring period, and the duration of the street lights on the controlled equipment group in the next monitoring period is set to Q1, Q1=2×L2; if the interval coefficient is greater than or equal to the interval threshold, it is determined that the controlled equipment group does not have a continuous feature during the monitoring period, and the duration of the street lights on the controlled equipment group in the next monitoring period is not optimized.

The lighting scene is identified according to the monitoring components distributed in the sub-areas, and the on / off control of all street lamps in the sub-areas is performed according to the identification results, thereby reducing the number of monitoring components that are continuously running, and avoiding the consumption of electric energy saved by street lamps at the monitoring end. Compared with the conventional one-lamp-one-monitoring method, which consumes electric energy at the monitoring end, the present invention triggers the on / off control of the group of lamps in the sub-area by any monitoring component, which significantly improves the lighting effect and reduces the long-term ineffective consumption of the monitoring end. The regional assessment module can be used to evaluate and analyze the rationality of the regional division of the park, and the number of times all control equipment groups light up during the monitoring cycle can be counted and analyzed to obtain the control deviation coefficient, so as to provide feedback on the overall energy consumption utilization rate of the monitoring equipment groups in the park based on the control deviation coefficient, so as to re-divide the sub-areas when necessary; The management optimization module can be used to perform management optimization analysis on the campus road lights, and redistribute local lighting control rights based on the expanded equipment groups and reduced equipment groups intercepted in the control sequence, so that the sub-area coverage area of ​​high-frequency street lights is increased, further improving the lighting effect of the campus street lights.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0015] Figure 1 is a system block diagram of Embodiment 1 of the present invention; Figure 2 This is a flow chart of the method of Embodiment 2 of the present invention. DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1: Figure 1 As shown, a park road lamp energy-saving control system based on data analysis includes an energy-saving control platform, which is communicatively connected to a regional division module, a control analysis module, a management optimization module and a regional evaluation module.

[0018] The area division module is used to segment the park: a segmentation method is randomly selected to divide the public lighting area of ​​the park into several sub-areas, and the segmentation methods include segmentation, center segmentation and block segmentation; the specific process of using segment segmentation for area segmentation includes: dividing the lighting roads in the park into several sub-roads according to main roads and branch roads, and the sub-areas are composed of the coverage of street lights in the sub-roads; the specific process of using center segmentation for area segmentation includes: dividing the public lighting area of ​​the park into several circular areas with equal areas, there may be some overlap between the circular areas, but there are no street lights in the overlapping areas, the number of street lights in each circular area is equal, and the circular areas are marked as sub-areas; the specific process of using block segmentation for area segmentation includes: dividing the public lighting area of ​​the park into several rectangular areas with equal areas, there is no overlapping between the rectangular areas, the number of street lights in each rectangular area is equal, and the rectangular areas are marked as sub-areas.

[0019] The number of street lamps installed in each sub-area is equal. The street lamps installed in the sub-area are marked as the control equipment group of the sub-area. A monitoring equipment group is allocated to the sub-area. The monitoring equipment group includes monitoring components such as sound sensors and cameras. The operating time period is allocated to the monitoring equipment group according to the geographical location of the park and the current climatic conditions. The operating time period is generally set from 18:00 to 8:00 the next day. The natural light intensity during the operating time period is low, and the monitoring equipment group is required to monitor and identify the lighting scene of the sub-area; the monitoring components in the monitoring equipment group are randomly allocated to the street lamp racks in the control equipment group of the sub-area.

[0020] The management and control analysis module is used to perform energy-saving management and control analysis on the street lights in the park: a monitoring cycle with a duration of L1 natural days is generated. During the operation period within the monitoring cycle, the monitoring components of the monitoring equipment group are used to analyze whether the sub-area is in a traffic scene: if so, all the street lights in the management and control equipment group in the sub-area are controlled to light up for L2 minutes through the controller, and all the street lights in the management and control equipment group are controlled to turn off after L2 minutes. L1 and L2 are both numerical constants, and the specific values ​​of L1 and L2 are set by the management personnel themselves; if not, no processing is performed; the public lighting area of ​​the park is divided into several sub-areas according to a random segmentation method, and the lighting scene is identified according to the monitoring components distributed in the sub-areas, and all the street lights in the sub-areas are turned on and off according to the identification results, so as to reduce the number of continuously running monitoring components and avoid the consumption of electric energy saved by street lights at the monitoring end. Compared with the conventional one-lamp-one-monitoring method, which consumes electric energy at the monitoring end, the present invention triggers the on-off control of the group of lamps in the sub-area by any monitoring component, which has a significant improvement in the lighting effect and reduces the long-term ineffective consumption of the monitoring end; It should be noted that the matching of monitoring components and street lamps can be randomly assigned or assigned using a fixed procedure (central image, peripheral divergence, etc.). The number of monitoring components in each group is less than the number of street lamps in the control equipment group, so as to reduce the energy consumption of the continuously running monitoring components. The use of monitoring components for lighting scene recognition is a mature existing technology. For example, when the monitoring component is a sound sensor, the volume decibel value is collected in real time during the operation period. When the volume decibel value exceeds the set recognition threshold, it can be determined that the sub-area is in the lighting scene, thereby triggering the opening and closing control of the management and control data group; when the monitoring component is a camera, the camera records the shooting area in real time, decomposes the video into frames of images, and then uses image recognition technology to extract traffic features such as pedestrians and vehicles in the image. If the extraction is successful, it can be determined that the sub-area is in the lighting scene.

[0021] The regional evaluation module is used to evaluate and analyze the rationality of the regional division of the park: at the end of the monitoring cycle, the number of times the control device group lights up during the monitoring cycle is obtained and marked as the on / off control value of the control device group, the variance of the on / off control values ​​of all control device groups during the monitoring cycle is calculated to obtain the control deviation coefficient, and the control deviation coefficient is compared with the preset control deviation threshold: if the control deviation coefficient is less than the control deviation threshold, it is determined that the rationality of the regional division of the monitoring cycle meets the requirements; if the control deviation coefficient is greater than or equal to the control deviation threshold, it is determined that the rationality of the regional division of the monitoring cycle does not meet the requirements, and other division methods are used at the beginning of the next monitoring cycle to re-divide the sub-areas of the park; the number of times all control device groups light up during the monitoring cycle is counted and analyzed to obtain the control deviation coefficient, so as to provide feedback on the overall energy consumption utilization rate of the monitoring device groups in the park based on the control deviation coefficient, so as to re-divide the sub-areas when necessary.

[0022] The management optimization module is used to perform management optimization analysis on the street lights in the park: arrange the control equipment groups in descending order of the opening and closing control values ​​to obtain a control sequence, and mark the L3 control equipment groups with the highest order and the L3 control equipment groups with the lowest order in the control sequence as expansion equipment groups and reduction equipment groups respectively. L3 is a numerical constant, and the specific value of L3 is set by the management personnel. At the beginning of the next monitoring cycle, the expansion equipment group and the reduction equipment group are reorganized and analyzed: the street lights at the edge of the sub-area of ​​the expansion equipment group are included in the expansion equipment group, and the street lights at the edge of the reduction equipment group are included in the adjacent control equipment groups. If the sub-areas corresponding to the two expansion equipment groups are adjacent, the expansion equipment groups of the two adjacent sub-areas share the control of the street lights at the junction; mark the L2 minutes that the control equipment group lights up during the monitoring cycle. For the control period, the interval duration between any two adjacent control periods is marked as the interval value, and the interval coefficient is obtained by summing up all the interval values ​​of the control equipment group in the monitoring period and taking the average value, and the interval coefficient is compared with the preset interval threshold: if the interval coefficient is less than the interval threshold, it is determined that the control equipment group has continuous characteristics in the monitoring period, and the street light on time of the control equipment group in the next monitoring period is set to Q1, Q1=2×L2; if the interval coefficient is greater than or equal to the interval threshold, it is determined that the control equipment group does not have continuous characteristics in the monitoring period, and the street light on time of the control equipment group in the next monitoring period is not optimized; according to the expansion equipment group and the reduction equipment group intercepted in the control sequence, the local lamp control rights are redistributed, so that the sub-area coverage area of ​​the high-frequency street lights is increased, and the lighting effect of the park street lights is further improved.

[0023] Embodiment 2: Figure 2 As shown, a method for energy-saving control of park road lamps based on data analysis includes the following steps: Step 1: Segment the park: randomly select a segmentation method to divide the park's public lighting area into several sub-areas, mark the street lamps installed in the sub-areas as the control equipment groups of the sub-areas, allocate monitoring equipment groups to the sub-areas, allocate operating time periods to the monitoring equipment groups, and randomly allocate the monitoring components in the monitoring equipment groups to the street lamp racks in the control equipment groups of the sub-areas; Step 2: Conduct energy-saving management and control analysis on the park road street lamps: Generate a monitoring cycle with a duration of L1 natural days. During the operating period within the monitoring period, when the analysis sub-area is determined to be in a traffic scene during the operating period, all street lamps in the control device group are controlled to light up; Step 3: Evaluate and analyze the rationality of the regional division of the park: obtain the control deviation coefficient at the end of the monitoring period, and use the control deviation coefficient to determine whether the rationality of the regional division of the monitoring period meets the requirements; Step 4: Conduct management optimization analysis on the park road street lights: Arrange the management and control equipment groups in descending order of the on / off control values ​​to obtain a control sequence, extract the expansion equipment group and reduction equipment group from the control sequence, and reallocate the control rights of the street lights of the expansion equipment group and the reduction equipment group.
