Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flow chart of an energy saving method based on power big data according to an embodiment of the present invention is shown, and an execution subject of the method shown in fig. 1 may be a software and/or hardware device. The execution bodies of the present application may include, but are not limited to, at least one of: user equipment, network equipment, etc. The user equipment may include, but is not limited to, computers, smart phones, personal digital assistants (Personal Digital Assistant, abbreviated as PDA), and the above-mentioned electronic devices. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of a large number of computers or network servers based on cloud computing, where cloud computing is one of distributed computing, and a super virtual computer consisting of a group of loosely coupled computers. This embodiment is not limited thereto. The method comprises the steps S1 to S4, and specifically comprises the following steps:
S1, acquiring a regional map of a target region, and receiving an installable position point selected by a user on the regional map based on a dividing end, traversing the position point, which is located at a radiation road in a communication relation with the installable position point, in the regional map as a radiation position point by taking the installable position point as a starting point and a preset road distance as a traversing range, wherein the communication relation comprises a direct communication relation and an indirect communication relation.
In practical application, the target area may be an area, when the map of the area is selected, the map corresponding to the corresponding area may be selected, after the map corresponding to the corresponding area is obtained, the staff may select some available plots in the map as installable position points capable of installing the charging pile, where when the installable position points are determined, the central position of the corresponding plots may be selected as the installable position points.
The predetermined road distance refers to a phase difference distance between the radiation position point and the mountable position point on the radiation road, and for example, one radiation position point may be determined at a road distance of 1km from the mountable position point.
The radiation road may be a road directly leading to the installable position point, i.e., a road directly communicating with the installable position point, or may be a road indirectly leading to the installable position point, i.e., a road indirectly communicating with the installable position point, for example, a branch road on a road directly communicating with the installable position point.
S2, determining a plurality of radiation areas corresponding to the mountable position points according to a range division strategy, the mountable position points and the radiation position points, counting the number of the charging piles in each radiation area to obtain the total number of the charging piles corresponding to the mountable position points, classifying the mountable position points with the total number of 0 to obtain a first set, and classifying the rest mountable position points to obtain a second set.
It will be appreciated that there may be a location point around the installable location point selected by the staff in step S1 where the charging pile has been installed, in which case the location point may not have a high requirement for installing the charging pile around a location point without other charging piles, so that in order to select a suitable location point to install the charging pile, the waste of energy during installation is reduced, and the invention further sorts the installable location point selected in step S1 in a subsequent step, and selects the most suitable location point for installation by sorting.
In order to sort the installable position points later, so as to select the most suitable installable position point for installing the charging pile, in step S2, the invention firstly sorts each installable position point to obtain two sorted sets, and then sorts the installable position points later according to the two sets.
Specifically, when classifying the installable position points, the invention firstly obtains the radiation area corresponding to each installable position point, classifies the installable position points with the total number of the charging piles of 0 in the radiation area by the number of the charging piles searched in the radiation area, and classifies the installable position points with the total number of the charging piles of more than 0 in the radiation area as another type.
When the charging piles cannot be searched in the radiation area around the mountable position point, the requirement for mounting the charging piles at the position point is possibly larger than that of the mountable position point of another type, so that the mountable position point can be classified into one type, the rest mountable position points are classified into another type, the mountable position point can be classified according to the influence degree of the other charging piles around the mountable position point on the mountable position point, and the position points with larger mounting requirements of the charging piles can be arranged in front when the charging piles are arranged in the follow-up sequence, so that the resource waste caused during mounting is reduced.
Wherein, in some embodiments, the above-mentioned radiation area can be obtained by:
s21, acquiring each mountable position point and the radiation position point corresponding to each mountable position point as a group of dividing combinations, taking each radiation position point in each dividing combination as a starting point and each mountable position point as an ending point, and generating a straight line dividing direction corresponding to each radiation position point.
It will be appreciated that each mountable location point may correspond to more than one radiation location point, so for convenience in determining the radiation area corresponding to each mountable location point, the present invention will take each mountable location point and the radiation location point corresponding to each mountable location point as a division combination, and will take each radiation location point as a starting point and the mountable location point as an ending point, and generate a straight line division direction from each radiation location point to the mountable location point.
S22, determining a first dividing line positioned at a preset angle on the first side of the straight line dividing direction and a second dividing line positioned at a preset angle on the second side of the straight line dividing direction based on the radiation position point.
The first side may be a left side in the straight line dividing direction, or may be a side selected according to an actual situation, and the second side may be a right side in the straight line dividing direction, or may be a side selected according to an actual situation.
S23, generating a fan-shaped radiation area corresponding to each radiation position point according to the first dividing line and the second dividing line.
It should be noted that the first dividing line and the second dividing line are the same length, and the length is the same as the distance between the radiation position point and the mountable position point.
When the radiation area is generated, the first dividing line and the second dividing line can be connected through a curve to generate a sector area, so that the closer the generated radiation area is to the mountable position point area, the larger the search range of the mountable position point area is, the larger the influence of the searched mountable position point on the mountable position point is, and the mounting requirement of the corresponding position point can be judged through other charging piles searched by the radiation area.
S24, obtaining a plurality of radiation areas corresponding to the mountable position points according to the radiation areas corresponding to the radiation position points.
Because the charging piles are communicated with the road generally, the radiation area generated by the method can reduce the area range when searching other charging piles, improve the efficiency during searching, and be more accurate during searching.
In addition, on the basis of the scheme, the invention further comprises the following scheme:
s25, acquiring the radiation roads from the mountable position points to the corresponding radiation position points, and generating range adjustment information if sub-road sections exist in the radiation roads and are not in the radiation areas corresponding to the corresponding radiation position points.
It will be appreciated that, since the angle at which the radiation area is generated in the above manner is preset, there may be a case where the road section existing between the radiation position point and the mountable position point is not within the radiation area, in which case there may be a case where some of the charging piles on the road are not searched at the time of the subsequent search, and thus the present invention further adjusts the radiation area in this case.
S26, acquiring a sub-road section which is not in a radiation area corresponding to the corresponding radiation position point as an adjustment road section based on the range adjustment information, and determining an adjustment side of the adjustment road section, wherein the adjustment side is a first side and/or a second side of the straight line dividing direction.
Specifically, when the situation mentioned in S25 occurs, the present invention may first acquire a corresponding adjustment road segment, that is, a road segment that is not in the radiation area, and then determine a side on which the adjustment road segment is located as an adjustment side, for example, if the adjustment road segment is on a first side in the straight line dividing direction, the first side is taken as an adjustment side, and if the adjustment road segment is on a second side in the straight line dividing direction, the second side is taken as an adjustment side.
S27, acquiring a first dividing line and/or a second dividing line corresponding to the adjustment side as an adjustment dividing line.
For example, if the adjustment side is the first side, the adjustment division line is the first division line, and if the adjustment division line is the second side, the adjustment division line is the second division line.
And S28, determining a supplementary dividing line positioned on the first side or the second side of the adjustment dividing line according to the adjustment road section.
Specifically, step S28 includes steps S281 to S283:
s281, obtaining a plurality of road section position points corresponding to the adjusted road section, taking the radiation position point corresponding to the adjusted road section as a starting point, and taking the road section position point as an ending point to generate a plurality of reference dividing lines.
S282, acquiring and adjusting the included angle formed by the dividing line and each reference dividing line, and determining the reference dividing line with the largest included angle as the selected dividing line.
When a plurality of reference dividing lines are obtained based on the adjustment road section, the reference dividing line having the largest included angle between the adjustment dividing line and the reference dividing line may be obtained as the selected dividing line in order to allow the enlarged radiation area to include the adjustment road section.
For example, referring to fig. 2, for a schematic diagram of an enlarged updated radiation area according to an embodiment of the present invention, when an adjustment road section in the figure is located at a second side, a second dividing line may be used as the adjustment dividing line, and an included angle between the second dividing line and a plurality of reference dividing lines (not shown in the figure) may be obtained, and then, a reference dividing line with a maximum included angle may be used as a supplementary dividing line.
And S283, extending the selected dividing line to obtain a supplementary dividing line, wherein the lengths of the line segments of the supplementary dividing line and the adjustment dividing line are the same.
It will be appreciated that the length of the line segment of the supplemental dividing line obtained in step S282 may be short, so that after the supplemental dividing line in step S282 is obtained, the present invention further extends the supplemental dividing line to a length consistent with the length of the adjusted dividing line.
And S29, generating a supplementary region based on the adjustment dividing line and the supplementary dividing line, and performing expansion updating on the radiation region based on the supplementary region to obtain an updated radiation region.
In generating the supplemental region, the adjustment dividing line and the supplemental dividing line may be connected by a curve to generate a sector-shaped region.
By the method, the radiation area can be further enlarged and adjusted, so that the radiation area can contain all radiation roads corresponding to the mountable position points, and the accuracy in the subsequent searching process is improved.
S3, processing the quantity of the radiation roads and the radiation road flow corresponding to the installable position points in the first set according to a first ordering strategy to obtain a first ordering sequence, processing the total quantity of the charging piles and the radiation road flow corresponding to the installable position points in the second set according to a second ordering strategy to obtain a second ordering sequence, and obtaining the installable sequence based on the first ordering sequence and the second ordering sequence, wherein the first ordering sequence is before the second ordering sequence.
It will be appreciated that the first ordered sequence is arranged before the second ordered sequence because the first ordered sequence is a mountable location point around which no other charging posts are located, which may require a greater mounting of the charging posts than the mountable location point in the second ordered sequence.
Specifically, the specific implementation manner of step S3 may be:
s31, counting the number of the radiation roads corresponding to each mountable position point in the first set, and obtaining a first ordering coefficient based on the ratio of the number of the radiation roads to the number of the reference roads.
It will be appreciated that, when there are more radiation roads corresponding to each mountable location point in the first set, the more vehicles may be routed to the mountable location point, the greater the mounting requirement of the mountable location point may be, so that the first ranking coefficient may be obtained according to the ratio of the number of radiation roads to the number of reference roads.
S32, counting first road flow of the radiation roads corresponding to the mountable position points in the first set in a historical time period, and obtaining a second ordering coefficient based on the ratio of the first road flow to the reference road flow.
The first road flow is the vehicle flow of the radiation road corresponding to the mountable position point in the historical time period, and the larger the vehicle flow is, the larger the mounting requirement of the corresponding mountable position point charging pile is likely to be, so that the second ordering coefficient can be obtained according to the ratio of the first road flow to the reference road flow.
S33, multiplying the first sorting weight, the first sorting coefficient and the second sorting coefficient to obtain a sort of sorting coefficient corresponding to each mountable position point in the first set.
The first ranking weight may be used to adjust a class of ranking coefficients, for example, when a class of ranking coefficients is too large, it may be subjected to a decreasing process by a class of ranking coefficients, and when a class of ranking coefficients is too small, it may be subjected to an increasing process by a class of ranking coefficients.
S34, sorting the installable position points in the first set in a descending order based on the sort of sorting coefficients to obtain a first sorting sequence.
The purpose of the descending order is to prioritize the installable site points where the installation requirements are greater.
And S35, obtaining a third sorting coefficient according to the ratio of the number of the reference charging piles to the total number of the charging piles corresponding to each mountable position point in the second set.
It will be appreciated that the greater the total number of charging piles associated with each mountable location point in the second set, the greater the number of charging piles around it, and the lesser the mounting requirements for that mountable location point, since the vehicle can be charged with other charging piles around it.
And S36, counting second road flow of the radiation roads corresponding to the mountable position points in the second set in the historical time period, and obtaining a fourth sorting coefficient based on the ratio of the second road flow to the reference road flow.
Likewise, the greater the traffic flow of the radiant road corresponding to the corresponding mountable location point in the second set over the historical period of time, the greater its mounting requirements for the charging stake may be.
And S37, multiplying the second sorting weight, the third sorting coefficient and the fourth sorting coefficient to obtain a class-II sorting coefficient corresponding to each mountable position point in the second set.
Similar to the generation of the first class of sorting coefficients, the second class of sorting coefficients can be generated by multiplying the second sorting weight, the third sorting coefficient and the fourth sorting coefficient.
S38, sorting the installable position points in the second set in a descending order based on the second sort coefficients to obtain a second sort sequence.
Likewise, the descending order of the installable site points in the second set is also to prioritize the installable site points that are more in need of installation.
Through the mode, the installable position points with larger installation requirements can be arranged in front, the installable position points with smaller installation requirements are arranged behind, and resource waste caused when the installable position points are selected according to the installable sequence in the follow-up process is reduced.
S4, acquiring the installation quantity corresponding to the target area, sequentially selecting installable position points which are consistent with the installation quantity in the installable sequence as selected position points, acquiring the installation quantity of the charging piles corresponding to each selected position point, and sending the selected position points and the installation quantity of the charging piles corresponding to each selected position point to an installation end.
The number of the installation can be preset or set by a user according to actual requirements. For example, if the number of installs is 10, there are 20 installable position points in the installable sequence, and the installable position points located in the first 10 installable positions in the installable sequence may be selected as the selected position points.
After the selected position points are obtained, in some embodiments, the number of installed charging piles corresponding to each selected position point may be obtained through the following steps:
s41, acquiring the charging piles in the radiation area corresponding to the selected position point and the occupied time of the charging piles in a preset time period, and acquiring the average occupied time corresponding to the selected position point according to the average value of the occupied time corresponding to all the charging piles.
The preset time period may be one day, for example, average occupation time of all charging piles corresponding to each selected position point in one day may be counted.
S42, obtaining a quantity adjustment coefficient according to the ratio of the average occupied time length to the reference occupied time length, and multiplying the quantity weight value, the quantity adjustment coefficient and the reference installation quantity to obtain the installation quantity of the charging piles corresponding to the corresponding selected position points.
It is understood that, when the average occupation period is larger, the vehicle charging requirement corresponding to the corresponding selected position point may be larger, so that the larger the number of charging piles corresponding to the corresponding selected position point may be set.
In addition, if the two position points are very close to each other when the position points are installed, in order to reduce the waste of resources, the charging piles do not need to be installed on the corresponding position points, so on the basis of the embodiment, the invention further comprises the following schemes:
a1, obtaining a total radiation area corresponding to each mountable position point according to the plurality of radiation areas corresponding to each mountable position point.
A2, acquiring a superposition area between the mountable position point positioned at the first position in the mountable sequence and the total radiation area corresponding to other mountable position points, and deleting the corresponding other mountable position points as deleting position points if the area of the superposition area is larger than a preset superposition area.
It will be appreciated that if the area of the overlapping area is greater than the preset overlapping area, the distance between the mountable position point located at the first position in the mountable sequence and the corresponding mountable position point may be very close, and two adjacent position points may cause resource waste if the charging pile is mounted on the adjacent position points, so that the mountable position point with smaller mounting requirement can be deleted when mounting is performed.
And A3, updating the installable sequence after deletion processing, continuously acquiring a superposition area between an installable position point positioned at a second position in the updated installable sequence and a total radiation area corresponding to other installable position points, and deleting the corresponding other installable position points as deletion position points if the area of the superposition area is larger than a preset superposition area.
Similarly, in the same manner as in step A2, after the first round of screening is performed based on the mountable location point located at the first position, the second round of screening may be performed based on the mountable location point located at the second position in the updated sequence, so that the mountable sequence may be further updated.
And A4, repeating the steps until the last installable position point in the installable sequence is obtained, stopping the steps, and obtaining the updated installable sequence.
By the method, the resource utilization rate of the installable position points in the installable sequence can be increased.
After obtaining the updated installable sequence, the invention further comprises the steps of:
and A5, counting the sum of the installation quantity of the charging piles of the deletion position points corresponding to the installation position points in the updated installable sequence to obtain the quantity of the deletion charging piles.
It can be understood that after deleting the deleted position point corresponding to each installable position point in the installable sequence, because each deleted position point corresponds to the installed number of the charging piles, after deleting the deleted position point, in order to enable the charging piles installed at the corresponding installable position point to meet the requirement, the invention also compensates the installed number of the charging piles corresponding to the corresponding installable position point according to the installed number of the charging piles at the deleted position point.
And A6, increasing and updating the number of the charging piles corresponding to the corresponding installable position points based on the number of the charging piles to obtain the number of the charging piles after updating the corresponding installable position points according to the upward rounding value of the ratio of the number of the charging piles to the number of the reference charging piles.
The more the number of the deleted charging piles is, the more the number of the charging piles to be added is required to be added, so that the number of the charging piles to be added corresponding to the corresponding installable position point can be increased and updated based on the upward rounding value of the ratio of the number of the deleted charging piles to the number of the reference deleted charging piles, and then the number of the charging piles to be added corresponding to the corresponding installable position point is increased and updated through the obtained number of the added charging piles.
By the method, the number of the charging piles which correspond to the installable position points of the deleted position points can be updated in a feedback manner, so that the number of the charging piles which correspond to the corresponding installable position points can meet the requirements.
