In order to make the technical solutions of the present disclosure better understood by those skilled in the art, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only some embodiments of the present disclosure, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the present disclosure may be described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to an embodiment of the present disclosure, a method for displaying large-scale simulation data is provided, as shown in fig. 1, the method includes the following steps 101 to 103:
step 101: acquiring simulation data generated by simulation in a preset time period, wherein the simulation data changes along with the change of simulation time.
In this embodiment, the simulation data includes simulation time and simulation data values, and the simulation data values corresponding to the same simulation object may be different due to different simulation times in the simulation process.
Step 102: establishing N storage units in a memory, comprising: the values of the initial pixels of the N storage units form an equal ratio sequence; and the pixels of each memory unit vary with the variation of the simulation time.
In this embodiment, N storage units for storing bitmaps (bitmaps) may be set in the memory, and this embodiment converts two-dimensional vector data that grows indefinitely into bitmap data that stores multiple storage units. The embodiment can realize the display of the two-dimensional vector data by calling bitmap data in each storage unit.
Each memory unit is built with a different initial pixel and the pixels can be dynamically changed. The number of the established storage units may be set based on the size of the memory, for example, 10, and is not limited herein. When each storage unit is called, the simulation data in a preset time period can be displayed; and the initial pixel value of each storage unit forms an equal ratio sequence, and the initial pixels of the storage units are sequentially from small to large: a. the1,2A1,4A1,……2n-1A1For example, the initial pixels of the N memory units are, in order from small to large: 128, 256, … … B1 x 29
As an optional implementation manner of this embodiment, the changing of the pixel of each storage unit with the change of the simulation time includes: in the preset time period, dividing the preset time period into a plurality of time periods with the same time length according to a time sequence by taking the simulation starting time point as a reference time point; in the simulation process, each storage unit is increased once by preset times on the basis of the initial pixel every time the simulation time goes through one time interval.
In the bookIn an alternative implementation, the preset simulation period may be divided into a plurality of time segments with equal length, the start time of the simulation is used as the reference time point, and the plurality of time segments may also form an equal ratio (or equal ratio) sequence, for example, T, 2T, 4T … … 2m- 1And T. Therefore, when the simulation time length is doubled, the pixel of the storage unit is doubled, so that the time length and the pixel ratio of the storage unit are ensured to be unchanged.
As an optional implementation manner of this embodiment, the method further includes: in the simulation process, the maximum value of the simulation data in the current time interval is obtained; when the pixel of each storage unit changes along with the change of the simulation time, if the maximum value of the simulation data changes to a preset value, each storage unit is increased once on the basis of the current pixel according to a preset multiple.
In this optional implementation manner, in the simulation process, since the simulated data has a large variation, and the display manner based on the current storage unit may not satisfy the display of the simulated data, the pixels in the storage unit need to be further adjusted based on the above optional manner. The pixels of the memory unit can thus be adjusted based on the variation of the maximum value in the simulation data. Lg may be determined firstMaxY
When lg is used as referenceMaxYAnd when the current storage unit is doubled, the pixels of the current storage unit are also doubled.
The 10-layer bitmap in this embodiment may be a typical sparse two-dimensional matrix, so that the memory consumption may be optimized subsequently by using an algorithm related to the sparse matrix, and the data processing efficiency is improved.
For ease of understanding, the storage units may be understood in terms of a layer concept, and the respective storage units may be determined first without considering that the simulation data size varies excessively:
with the time axis as the X-axis, the first starting pixel of the B1 layer is, for example, 128 pixels. And (3) corresponding the time length T of the current simulation data, such as 5 minutes, to B1, wherein B1 is increased according to the following rule, and every time T is doubled, the value of B1 is doubled, so that the time length and the pixel ratio of the bitmap of the current layer are ensured to be unchanged.
For the B2 layer, the B2 original pixel is 2 times that of B1, also doubling with T.
Such a hierarchy may be ten levels B1, B2, B3 … … B10, all doubled with T, where B10-B1-29=512*B1。
On the other hand, when the simulation data has an excessively large variation, the variation of the pixels can be realized from another dimension, and the Y axis is described as a Y axis, and since N layers are established based on the time axis, the Y axis also corresponds to the N-layer structure, where the initial pixel is M1, and the maximum value MaxY of the simulation data is set to Y ═ lgMaxYMapping y to M1/2
The Y axis is also divided into 10 layers, M1, M2, M3 … … M10, the pixel values are also the same as the X axis, each layer is 2 times the previous layer, and each time lg isMaxYAnd when doubling, doubling the current Y-axis pixel value, and ensuring the proportion of the Y axis.
Therefore, a 10-layer dynamically changing logical bitmap in the memory is established through the steps. For each simulation value s ═ x, y, where x is time and y is simulation data, the simulation value is plotted in the N-level bitmap, and each level can show different details of the simulation data because the scale of each level is different.
Step 103: and respectively storing the simulation data into the N storage units in a bitmap mode so as to display the simulation data in the N storage units.
In this embodiment, when the simulation data needs to be displayed in the form of a bitmap on the interface, each storage unit can be called at the same time to obtain N display images.
As an optional implementation manner of this embodiment, the method further includes: in response to receiving a request for amplifying and displaying the simulation data of any storage unit, calling the simulation data of the next storage unit in the sequence in equal proportion to the simulation data; or, in response to receiving a request for displaying the simulation data of any storage unit in a reduced size, the simulation data of the last storage unit in the series in equal proportion to the simulation data is called.
In the optional implementation manner, if the user selects the zoom-in operation, the bitmap of the next layer of the current layer is directly displayed on the desktop physical window, if the zoom-in operation is selected, the bitmap of the previous layer is displayed, and if the zoom-in operation is selected to be zoomed out to the topmost layer, the bitmap of the topmost layer is directly zoomed in and out in an equal proportion mode. The method avoids the process of data redrawing.
As an optional implementation manner of this embodiment, the method further includes: and responding to a received request for amplifying and displaying the data set of any storage unit, determining the storage unit adapted to the simulation data set, and calling the storage unit to realize the display of the simulation data set.
In this optional implementation, if the user selects a segment of data for enlarged display, the layer of graphics most suitable for display can be calculated according to the ratio of the selection box of the user to the current x-axis, and a part of bitmaps corresponding to the graphics can be displayed.
As an optional implementation manner of this embodiment, the method further includes: in response to receiving a request for operating the simulation data point of any storage unit, determining the coordinate corresponding to the point in each storage unit, and determining the simulation data corresponding to the coordinate of each storage unit.
In this optional implementation, if the user wants to select a point for operation, the corresponding coordinates of the user in each virtual layer are easily calculated according to the pixel coordinates selected by the user in the current window, and the simulation data corresponding to the corresponding coordinates selected by each layer are collected and used as the data selected by the user.
Through the optional implementation mode, no matter the simulation data is selected, zoomed and the like, the bitmap does not carry out redrawing operation, and the display efficiency is greatly improved.
In the embodiment, two-dimensional vector data which is wirelessly increased is converted into multilayer bitmap data, so that the problems that in the operation process (selection, reduction, amplification, frame selection and the like), the display efficiency is low and the display is incomplete under a huge data scale due to the fact that simulation data needs to be redrawn are solved, the internal consumption is avoided, and the system processing performance is improved.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
