Description

Technical Field

[0001] The present invention relates to the technical field of smart street lamps, and in particular to an energy-saving smart street lamp management method and system. Background Art

[0002] At present, in the process of urbanization, street lamps, as part of the infrastructure of urban construction, consume huge amounts of energy. Although some existing technologies use advanced energy storage technologies such as solar energy technology, advanced communication control technologies such as the Internet of Things, and big data analysis technologies to remotely calculate and control smart street lamps, thereby saving energy consumption of smart street lamps, and by considering parameters such as pedestrian or vehicle traffic to reflect the use of street lamps, big data analysis is performed to achieve time-sharing control of smart street lamps, thereby saving energy consumption of smart street lamps.

[0003] However, in the prior art, when the pedestrian flow of smart street lamps is grouped and analyzed, that is, when the grouping information of the smart street lamps is determined, the historical pedestrian flow data and the control circuit grouping information of the smart street lamps are not taken into consideration, and thus there may be unreasonable decisions in the grouping control scheme. For example, the smart street lamps in some roads with large differences in pedestrian flow are divided into a group for analysis and control, which leads to poor energy-saving control effects of the smart street lamps, or the command street lamps that do not belong to the same control circuit are divided into a group for analysis and control, resulting in a waste of communication resources in the control process of the smart street lamps. For example, the Chinese invention patent with application number "CN202311091568.4" and invention name "An energy-saving smart street light management method and system based on the Internet of Things" discloses an energy-saving smart street light management method and system based on the Internet of Things, which involves the field of smart city technology, including: communication testing of all smart street lights; obtaining smart street light grouping information; obtaining pedestrian flow data in various parts of the city; predicting and calculating the pedestrian flow at each road location at each time point within a preset time period; screening out high-flow moment, medium-flow moment and low-flow moment; setting the street light lighting power for high-flow moment, medium-flow moment and low-flow moment respectively according to the street light lighting power setting logic; generating a control signal according to the lighting power setting data of the smart street light within the preset time period and sending it to the smart street light. The advantage of the present invention is that the present solution does not require the sensing components to work uninterruptedly for a long time to realize the intelligent control and management of street lights, which can effectively reduce the management energy consumption of smart street lights and is conducive to the construction of energy-saving smart cities. However, this patent does not take into account the historical pedestrian flow data and the control circuit grouping information of the smart street lights when determining the grouping information of the smart street lights, and thus there may be unreasonable decisions in the grouping control scheme. For example, the smart street lights in some roads with large differences in pedestrian flow are divided into a group for analysis and control, resulting in poor energy-saving control effects of the smart street lights, or the command street lights that do not belong to the same control circuit are divided into a group for analysis and control, resulting in a waste of communication resources in the control process of the smart street lights.

[0004] Therefore, the present invention proposes an energy-saving smart street lamp management method and system. Summary of the invention

[0059] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0060] Embodiment 1:

[0062] S1: Based on the historical traffic data of each straight road in the management area and the control circuit grouping information of all smart street lamps, all re-divided roads in the management area are determined;

[0063] S2: Determine the grouping information of smart street lamps based on the geographical distribution data of all smart street lamps in the management area and all re-divided roads in the management area;

[0064] S3: Based on the historical passenger flow data of each re-divided road section, all passenger flow time sections of each re-divided road section within a unit time period are determined, and the average passenger flow data of each passenger flow time section of each re-divided road section within the unit time period is determined;

[0065] S4: Based on the average traffic flow data of each traffic zone in each unit time period of each re-divided road and the smart street light grouping information, the lighting power of all smart street lights in the management area is grouped and set to obtain the smart street light energy-saving management results.

[0066] In this embodiment, the management area is the geographical area covered by the smart street lamps to be managed in the energy-saving command street lamp management method.

[0067] In this embodiment, the straight road is a road extending in a straight extension direction, and the straight extension directions of the connected straight roads are different.

[0068] In this embodiment, the control circuit grouping information of the smart street lamp is information including the grouping method or strategy for grouping control of the smart street lamp in the control circuit of the smart street lamp. For example, all the smart street lamps on the straight road A and the straight road B are controlled simultaneously as the same group, that is, the lighting power of the smart street lamps in the same group can only be set to the same value at the same time.

[0069] In this embodiment, the re-divided road is a road consisting of straight roads that are connected to each other and have similar passenger flow, and are controlled by the same group of command street lamps in the control circuit.

[0070] In this embodiment, the geographical distribution data of the smart street lamps are the specific distribution position data of the smart street lamps on different straight roads, which can be represented by three-dimensional coordinates in the world coordinate system or by text descriptions such as: which street lamp belongs to which road, from which direction to which direction.

[0071] In this embodiment, the smart street lamp grouping information is information indicating the grouping situation of the smart street lamps, wherein one group in the smart street lamp grouping situation includes all the smart street lamps on a single re-divided road.

[0072] In this embodiment, based on the geographical distribution data of all smart street lamps in the management area and all re-divided roads in the management area, the smart street lamp grouping information is determined as follows:

[0073] Based on the geographic distribution data of all smart street lamps in the management area, all smart street lamps belonging to a single re-divided road in the management area are divided into a group to obtain smart street lamp grouping information.

[0074] In this embodiment, the unit time period is a pre-set period for cyclic control of the smart street light, for example: 24 hours, 1 year, or one week.

[0075] In this embodiment, the time periods divided by the flow of people are time periods divided according to the flow of people contained in the unit time period, for example, a high flow of people time period, a medium flow of people time period, and a low flow of people time period.

[0076] In this embodiment, the average passenger flow data of each passenger flow zone in each unit time period of each re-divided road is determined, including:

[0077] The average of the passenger flow at all historical moments in each traffic zone of each re-divided road within a unit historical period is taken as the average passenger flow data of each traffic zone of each re-divided road within a unit period.

[0078] In this embodiment, based on the average flow data of each traffic zone in each unit time period of each re-divided road and the smart street lamp grouping information, the lighting power of all smart street lamps in the management area is grouped and set to obtain the smart street lamp energy-saving management results, including:

[0079] Retrieve the average passenger flow data-lighting power table to determine the required lighting power corresponding to the average passenger flow data of each passenger flow zone in each unit time period for each re-divided road section;

[0080] And the lighting power of a group of smart street lights corresponding to each re-divided road in the smart street light grouping information is set to the corresponding required lighting power to obtain the smart street light energy-saving management result.

[0081] The beneficial effects of the above technology are: when determining the grouping information of smart street lights, the historical pedestrian flow data and the control circuit grouping information of the smart street lights are taken into consideration, which to a certain extent avoids the occurrence of unreasonable decisions in the smart street light grouping control scheme, and also avoids dividing the smart street lights in some roads with large differences in pedestrian flow into a group for analysis and control, and also avoids dividing the command street lights that do not belong to the same control circuit into a group for analysis and control. The lighting power of smart street lights in a large management area is grouped and set to reduce the energy waste of smart street lights in a large management area and the waste of communication resources in the street light control process.

[0082] Embodiment 2:

[0083] Based on Example 1, S1: Based on the historical traffic data of each straight road in the management area and the control circuit grouping information of all smart street lamps, all re-divided roads in the management area are determined, referring to Figure 2 ,include:

[0084] S101: Based on the historical passenger flow data of each straight road in the management area, all straight roads in the management area are merged to obtain all initially divided roads in the management area;

[0085] S102: Divide all initially divided roads in the management area based on the control circuit grouping information of all smart street lamps in the management area to obtain all re-divided roads in the management area, including:

[0086] Among all the initially divided roads in the management area, part of the initially divided roads including the smart street lamps in the single group of smart street lamps that are simultaneously controlled in the control circuit grouping information are regarded as re-divided roads among the initially divided roads.

[0087] The beneficial effects of the above technology are: by utilizing the historical pedestrian flow data of each straight road in the management area and the control circuit grouping information of all smart street lights, the straight roads in the management area can be merged and divided, thereby avoiding the smart street lights in some roads with large differences in pedestrian flow being divided into a group for analysis and control, and also avoiding the command street lights that do not belong to the same control circuit being divided into a group for analysis and control, that is, to a certain extent, avoiding the occurrence of unreasonable decisions in the smart street light grouping control scheme.

[0088] Embodiment 3:

[0089] On the basis of Example 2, S101: based on the historical passenger flow data of each straight road in the management area, all straight roads in the management area are merged to obtain all initially divided roads in the management area, including:

[0090] Obtain the passenger flow of each straight road section in the management area at each historical moment within a unit historical period as the historical passenger flow data of each straight road section;

[0091] For the historical passenger flow data of each straight road, the passenger flow of each straight road at all historical moments in a unit historical period is averaged to obtain the average passenger flow of each straight road;

[0092] Based on the difference in passenger flow between two straight roads in the management area at the same historical moment and the average passenger flow of each straight road, the comprehensive passenger flow difference between two straight roads in the management area is calculated;

[0093] Based on the comprehensive passenger flow difference between two straight roads in the management area, all the straight roads in the management area are merged adjacently to obtain all the initially divided roads in the management area.

[0094] In this embodiment, the unit historical period is a unit period that has already passed.

[0095] In this embodiment, the historical moments are moments in the unit historical moment that are spaced apart by a preset period.

[0096] In this embodiment, the pedestrian flow is the number of people entering the intersection through the corresponding straight road within a preset period, wherein the preset period is the time interval between adjacent historical moments in a unit historical period. Secondly, the pedestrian flow is achieved using the existing headcount counting method.

[0097] In this embodiment, the comprehensive passenger flow difference indicates the difference between the passenger flows of two straight roads.

[0098] In this embodiment, adjacent merging is to connect adjacent straight roads end to end (maintaining the original geographical distribution position during the connection process).

[0099] The beneficial effects of the above technology are: a clear meaning of the historical pedestrian flow data of each straight road is given, and the average pedestrian flow of each straight road is calculated based on the historical pedestrian flow data of each straight road, and an accurate calculation method for the comprehensive pedestrian flow difference between two straight roads is given. Based on the comprehensive pedestrian flow difference, adjacent merging of straight roads is achieved under the condition of considering a small difference in pedestrian flow.

[0100] Embodiment 4:

[0101] On the basis of Example 3, based on the difference in the passenger flow of two straight roads in the management area at the same historical moment and the average passenger flow of each straight road, the comprehensive passenger flow difference of two straight roads in the management area is calculated, including:

[0102] The ratio of the difference in the passenger flow of two straight roads in the management area at each same historical moment to the average of the average passenger flow of the two corresponding straight roads is regarded as the difference in the passenger flow of the two corresponding straight roads at the corresponding historical moment;

[0103] Based on the principle of the closer the greater, the weight of the difference at each historical moment in the unit historical period is determined;

[0104] The sum of the products of the difference in passenger flow between each two straight roads at all historical moments and the combined weight of the difference is taken as the comprehensive passenger flow difference of the corresponding two straight roads.

[0105] In this embodiment, the difference in passenger flow represents the difference in passenger flow between two straight roads at a single historical moment.

[0106] In this embodiment, the closer the greater the principle is that the closer the historical moment is to the current moment, the greater the corresponding difference merging weight.

[0107] In this embodiment, the difference merging weight of each historical moment in the unit historical period is determined based on the principle of the closer the greater the difference, the weight is:

[0108] The ratio of the difference between each historical moment and the current moment to the maximum value of the difference between all historical moments and the current moment in the unit historical period is taken as the ratio of each historical moment;

[0109] The ratio of 1 to each historical moment is taken as the combined weight of the difference of the corresponding historical moment.

[0110] In this embodiment, the difference merging weight represents the proportion of the passenger flow difference at the corresponding historical moment in the comprehensive passenger flow difference of the corresponding two straight roads.

[0111] The beneficial effects of the above technology are: the difference in the flow of people on the two straight roads at each historical moment is calculated in turn, the difference at each historical moment in the unit historical period is combined with the weight, and then the comprehensive difference in the flow of people on the two straight roads is accurately calculated by weighted summation.

[0112] Embodiment 5:

[0113] On the basis of Example 3, based on the comprehensive passenger flow difference between two straight roads in the management area, adjacent straight roads in the management area are merged to obtain all the initially divided roads in the management area, including:

[0114] Among all adjacent straight roads of each straight road in the management area, adjacent straight roads whose comprehensive passenger flow difference does not exceed a first difference are selected and hypothetically merged with the corresponding straight roads to obtain a first merged road group;

[0115] If a single straight road in the first merged road group only belongs to the current first merged road group, two straight roads in the current first merged road group are merged adjacently to serve as the first divided road in the management area;

[0116] If a single straight road in the first merged road group does not only belong to the current first merged road group, then determining the comprehensive passenger flow difference between all straight roads in at least two first merged road groups to which the corresponding straight road belongs;

[0117] It is determined whether the maximum value of all currently calculated comprehensive passenger flow differences exceeds the second difference. If so, two straight roads in the first merged road group with a smaller comprehensive passenger flow difference among at least two first merged road groups to which the corresponding straight road belongs are adjacently merged as the first divided roads in the management area;

[0118] Otherwise, all the straight roads in the at least two first merged road groups to which the corresponding straight road belongs are merged adjacently to obtain a first divided road;

[0119] Based on all the first divided roads in the management area, all the preliminarily divided roads in the management area are obtained.

[0120] In this embodiment, the first difference is a difference threshold corresponding to the total number of straight roads being 2 in the preset list of total number of straight roads-difference threshold.

[0121] In this embodiment, it is assumed that the merging is a process of merging a group of adjacent straight roads into a first merged road group.

[0122] In this embodiment, all the comprehensive pedestrian flow differences currently calculated are the comprehensive pedestrian flow differences between all pairs of straight roads in all the straight roads in the at least two first merged road groups to which the straight roads belong.

[0123] In this embodiment, the second difference is a preset straight road total number-difference threshold list, and the corresponding difference threshold is when the straight road total number is the total number of all straight roads in at least two first merged road groups to which the straight road belongs.

[0124] The beneficial effects of the above technology are: based on the adjacent distribution of straight roads in adjacent straight roads whose comprehensive passenger flow difference does not exceed the first difference, and determining the difference threshold based on the number of straight roads included, the judgment and merging of adjacent straight roads whose comprehensive passenger flow difference does not exceed the first difference are realized, thereby completing the first adjacent merging of all straight roads in the managed roads.

[0125] Embodiment 6:

[0126] On the basis of Embodiment 5, based on all first divided roads in the management area, all initially divided roads in the management area are obtained, including:

[0127] Hypothetically merge the first divided roads connected within the management area to obtain all second merged road groups within the management area;

[0128] Based on all the second merged road groups within the management area, adjacently merge all the first divided roads within the management area to obtain all the second divided roads within the management area;

[0129] All second divided roads in the management area are continuously merged adjacent to each other to obtain all initially divided roads in the management area.

[0130] In this embodiment, it is assumed that the merging is a process of merging adjacent first divided roads into a second merged road group.

[0131] In this embodiment, all second divided roads in the management area are continuously merged adjacent to each other to obtain all initially divided roads in the management area, including:

[0132] According to "hypothetically merging the first divided roads connected in the management area to obtain all the second merged road groups in the management area; based on all the second merged road groups in the management area, adjacently merging all the first divided roads in the management area to obtain all the second divided roads in the management area", adjacent merging is continued for all the second divided roads in the management area until there are no roads meeting the adjacent merging conditions in the management area (i.e., assuming that the maximum value of the comprehensive passenger flow difference between the two straight roads in the merged road combination exceeds the corresponding difference threshold, and the difference threshold is still determined by retrieving the preset total number of straight roads - difference threshold list), all the initially divided roads in the management area are obtained.

[0133] The beneficial effect of the above technology is: by assuming that the first divided roads connected in the management area are merged again to determine whether to perform adjacent mergers, the second merger of roads in the management area is achieved, and the merger is executed cyclically using this logic to obtain all the initially divided roads in the management area.
