The method for drafting of thermodynamic chart can be applied in the electronic equipment for drawing thermodynamic chart, such as: terminal, server etc..It is described
The method for drafting of thermodynamic chart may include steps of:
Step 101: obtaining the heating power data of all subregion in target drawing area.
In the present embodiment, target drawing area is the drawing area of thermodynamic chart, can usually be preset by user, example
Such as: the specified population thermodynamic chart for drawing Beijing of user, then target drawing area is exactly Beijing.
In the present embodiment, the subregion can be divided in advance based on preset rules, such as: it can be according to longitude and latitude
Degree in advance by target drawing area or include target drawing area region division be multiple subregions.It is with CHINESE REGION
Example, can be divided into multiple subregions for CHINESE REGION in advance, and when drawing the thermodynamic chart of target drawing area, can be based on should
Divided subregion carries out subsequent operation in target drawing area.It is of course also possible to after determining target drawing area, it will
Target drawing area is divided into multiple subregions, and the application is not particularly limited this.
In the present embodiment, the subregion can be geographic grid.Still by taking CHINESE REGION as an example, if the warp in two places
Spend it is identical, latitude difference 0.01, then the actual range in the two places is approximately 700 meters；If the longitude difference in two places
0.01, latitude is identical, then the actual range in the two places is approximately 1000 meters.It, can be by the integer of latitude coordinates based on this
Part all places identical with front two decimal are divided into the same geographic grid, such as: latitude coordinates (116.33,
39.99) (preceding be longitude then be latitude) is geographically approximately one wide 700 meters long 1000 meters of rectangle geographic grid, longitude
Integer part and front two decimal be 116.33, and all places that the integer part of latitude and front two decimal are 33.99
The geographic grid is belonged to, such as the place etc. that latitude coordinates are (116.337579,39.991262).
In practical applications, thermodynamic chart usually has timeliness, can be used for indicating some specified dimension in a period of time
Heating power situation, the present embodiment are based on ready-portioned subregion, and all subregion is when default in available target drawing area
Heating power data in section.Wherein, the preset period of time can be specified by user's connected applications scene, such as: for population heat
Try hard to, which can be appointed as nearly 1 year；For the thermodynamic chart of traffic congestion, which can be referred to
It is set to 5 minutes etc..
In the present embodiment, for drawing the about thermodynamic chart of vehicle dense traffic degree, the heating power data can be pre-
If the about vehicle quantity on order in the period, the preset period of time can be nearly 30 minutes, nearly 60 minutes etc..As an example it is assumed that with
The thermodynamic chart of Beijing's about vehicle dense traffic degree is drawn at family in 19:00, then 18:30 in each sub-regions in available Beijing
To the about vehicle quantity on order of 19:00, it is assumed that latitude coordinates belong to (116.33,39.99) this subregion in 18:30 to 19:00
Interior about vehicle order has 100, then the heating power data of the subregion is 100 in the period.
Step 102: the heating power rank of the subregion is determined according to the heating power data.
Based on abovementioned steps 101, getting in target drawing area after the heating power data of all subregion, it can be according to heat
Force data determines the heating power rank of subregion.
In one example, the heating power data of all subregions can be summarized, and determined in all heating power datas
Minimum value and maximum value.Then the minimum value to the numerical intervals that the maximum value forms can be divided into multiple numerical value sub-districts
Between, the i.e. corresponding heating power rank in each numerical value subinterval.
As an example it is assumed that in the heating power data of all subregions got, minimum value 100, maximum value 400,
Heating power data [100,400] can be then divided into [100,200), [200,300), [300,400] three sections.Wherein,
[100,200) heating power rank 1 is corresponded to, [200,300) correspond to heating power rank 2, [300,400] corresponding heating power rank 3.If obtained
Heating power data to a certain subregion is 133, then can determine that the heating power rank of the subregion is heating power rank 1.
In another example, the timing really of heating power rank is being carried out, it can also be by all subregions according to heating power data
Sequence from small to large is arranged, then by all sub-zone dividings after arrangement be the identical heating power grade of multiple subregion quantity
Not.
As an example it is assumed that there is 6 sub-regions, the heating power data of all subregion got is as shown in table 1 below:
| Subregion | Subregion 1 | Subregion 2 | Subregion 3 | Subregion 4 | Subregion 5 | Subregion 6 |
| Heating power data | 100 | 145 | 132 | 356 | 213 | 323 |
Table 1
This six sub-regions is arranged according to the sequence of heating power data from small to large, rank results shown in available table 2:
| Subregion | Subregion 1 | Subregion 3 | Subregion 2 | Subregion 5 | Subregion 6 | Subregion 4 |
| Heating power data | 100 | 132 | 145 | 213 | 323 | 356 |
Table 2
It is assumed that presetting each heating power rank includes 2 sub-regions, then subregion 1 and subregion 3 can be divided into
Heating power rank 1, is divided into heating power rank 2 for subregion 2 and subregion 5, and subregion 6 and subregion 4 are divided into heating power rank
3。
Step 103: the identical adjacent subarea domain of heating power rank is merged.
Step 104: being that the target drawing area draws thermodynamic chart according to amalgamation result.
Based on abovementioned steps 102, after the heating power rank of all subregion has been determined, it can be directed to each subregion, by this
Subregion and adjacent subarea domain identical with its heating power rank merge, and are the target drawing area according to amalgamation result
Draw thermodynamic chart.
As an example it is assumed that the latitude coordinates of subregion 1 are (116.33,39.99), the latitude coordinates of subregion 2 are
(116.34,39.99), then the two subregions are geographically adjacent.Assuming that the heating power rank of subregion 1 and subregion 2
It is heating power rank 2, then can merges subregion 1 and subregion 2, it is subsequent when drawing thermodynamic chart, it can be based on son
It is drawn in region after region 1 and subregion 2 merge.
It can be right according to the heating power rank of all subregion in target drawing area by the application it can be seen from above description
The identical adjacent subarea domain of heating power rank merges, and is that the target drawing area draws thermodynamic chart according to amalgamation result.
During the entire process of thermodynamic chart is drawn, it is not necessary that the heating power data got is repeatedly traversed and calculated, greatly reduce
Calculation amount reduces the processing pressure of equipment, promotes the receipt rate of thermodynamic chart.
