Description

Technical Field

[0001] The present invention relates to the technical field of project supervision, and in particular to a method, device, equipment and medium for adaptively generating a time scale of a project progress chart. Background Art

[0002] As an important progress management tool, time-scaled network diagrams are widely used in various engineering projects. Using time as the horizontal axis, they intuitively display the timing and logical relationships of project steps, helping project managers maintain overall control, coordinate resources, and monitor progress. However, in large-scale project construction scenarios, traditional time-scaled network diagrams, which use uniform time scales, exhibit numerous drawbacks. The construction cycle of hydropower projects often stretches for years or even decades, involving complex processes that can reach hundreds or even thousands. The intensity of these processes varies greatly during different construction periods. For example, in the early stages of a project, processes such as site leveling and foundation construction are relatively concentrated; in the middle and later stages, processes such as equipment installation and commissioning are staggered. If a uniform time scale is used, the network diagram will become severely congested in the process-intensive central area, with overlapping lines and text, making it difficult to clearly distinguish the start and end times and logical relationships of each process. The sparse areas on both sides, during the early and late stages of construction, will appear loose, resulting in a serious waste of drawing space. This not only significantly affects the aesthetics of the network diagram but also reduces its readability, making it difficult for project managers to quickly and accurately obtain key information and increasing the difficulty of decision-making.

[0003] At the same time, during the printing process, due to the uneven distribution of drawing information, the entire map often needs to be scaled to ensure the clarity and readability of key areas. However, this can cause some areas to be too small or too large, affecting the printing effect and ease of use, and failing to meet the actual needs of project site construction guidance, meeting reports, etc. To improve this situation, the industry has conducted numerous studies and proposed several improvement methods. For example, some methods attempt to manually adjust the time scale interval. However, this method not only relies on operator experience and is highly subjective, but also requires a huge workload and is inefficient when faced with massive amounts of process data, making it difficult to ensure the accuracy and rationality of the adjustments. There are also some automatic adjustment algorithms based on fixed rules, such as simply dividing time intervals by the number of processes or time spans. However, because they do not fully consider the actual characteristics and distribution patterns of drawing elements, they cannot accurately adapt to changes in process density over different time periods and still cannot fundamentally solve the problem of uneven drawing information. Summary of the Invention The present invention provides a method, device, equipment and medium for adaptively generating a time scale of a project progress chart, so as to solve the problems of uneven drawing information, difficult scale adjustment and low adjustment efficiency in existing scale generation methods.

As used herein, the singular form is intended to also include the plural form, unless the context clearly indicates otherwise. Unless otherwise specified, all terms used herein (including technical terms and scientific terms) have the same meaning as those commonly understood by those skilled in the art to which the various embodiments of the present invention belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meaning as the contextual meaning in the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in the various embodiments of the present invention.

[0020] Embodiments of the present invention provide a method, device, equipment, and medium for adaptively generating a time scale for a project progress diagram. Based on the innovative concept of "maximum differential value of drawing element width," this method automatically calculates an adaptive time scale based on the density of process steps in different time periods by selecting controlling drawing elements, ensuring relatively uniform drawing information. This invention also provides technical support for the creation of dual-code time-scaled network diagrams.

[0021] See Figure 1 , Figure 1 FIG2 is a flow chart of a method for adaptively generating a time scale of a project progress chart according to an embodiment of the present invention, which specifically includes the following steps.

[0022] 1. Establish a micro-element scale sequence (see steps S1 and S2 for details).

[0023] S1, extracting the construction time interval of the project based on the process progress data of the project; S2, continuously slice the construction time interval to obtain multiple continuous micro-time units and generate a micro-time unit scale sequence.

[0024] Among them, S1 specifically is: extracting the start time node and end time node of the engineering project from the process progress data of the engineering project, and obtaining the project time interval from the start time node to the end time node; among them, the start time node is the earliest time in the process progress data, and the end time node is the latest time in the process progress data.

[0025] In step S2, the project time interval is continuously divided using the same time step to obtain micro-time units, i.e., time differential units. Preferably, the minimum time unit used in the process progress data is used as the slicing step.

[0026] Specifically, step S2 preferably adopts the following method: S2-1, extract the minimum time unit used in the process progress data, use the minimum time unit as the slicing step, and continuously slice the construction time interval into multiple micro-hours. The length of each micro-hour is the minimum time unit; S2-2, based on the start time and length information of each micro-element, generate a micro-element ruler sequence: ,in, Indicates the j A micro-hour, m Indicates the total number of micro-element, It is a two-dimensional vector that records the start time and length of the micro-element, as well as the time granularity to which the micro-element belongs.

[0027] Furthermore, after establishing the micro-element scale sequence, the process also includes clustering the micro-element according to different time granularities, grouping the micro-element into categories based on the different time granularities. Specifically, time granularities can be divided into: year, season, month, ten-day period, week, day, hour, etc. The micro-element is stored in a tree structure, making it easy to read the different time granularities to which the micro-element belongs, and to facilitate clustering and summation to obtain time scales of different time granularities (day, month, year).

[0028] 2. Establish a drawing element set (see steps S3 and S4 for details).

[0029] S3, extract all drawing elements from process progress data and establish a drawing element set , Contains the start and completion time of the drawing elements and the annotation text content.

[0030] S4, calculating the width of the micro-element contained in the drawing element, traversing and calculating all the drawing elements, and obtaining at least one width value corresponding to each micro-element.

[0031] See also Figure 2 The flowchart of the drawing element width differentiation method shown in FIG. 4 is as follows: in step S4, for each drawing element The following processing is performed: S4-1, extracting drawing elements The corresponding start time node and completion time node, and based on the start time node and completion time node, determine the drawing elements The micro-element included; S4-2, according to the drawing elements Text style, annotation style, determine the drawing elements Drawing width ; S4-3, according to the drawing elements Drawing width and the contained micro-element, calculate the drawing element width value of each micro-time unit contained .

[0032] In step S4, after processing all drawing elements, each micro-time unit has at least one width value, and when there is only one width value, it is the default drawing width of the micro-time unit, and when there are two or more, one is the default drawing width, and the rest are the drawing widths of the drawing elements taken calculated width value .

[0033] In some embodiments, the drawing elements include real process and annotated text of the double code network diagram, virtual process and annotated text of the double code network diagram, floating time and annotated text of the double code network diagram, and scale and annotated text.

[0034] Further, in step S4-2, the drawing width of the drawing element is determined according to the text style and annotation style of the drawing element , which specifically includes the following calculation method.

[0035] For the real process, virtual process and floating time of the double code network diagram, the drawing width of the drawing element is calculated as: drawing width = double code circle radius × 2 + safety distance + annotated text width; For the scale, the drawing width of the drawing element is calculated as: drawing width = safety distance + annotated text width; Wherein, the annotated text width calculation formula is: annotated text width = text height × text character number / 2 × text width-height ratio; The safety distance calculation formula is: safety distance = text height × text width-height ratio.

[0036] Traverse all drawing elements to form a width set , corresponding to one by one.

[0037] In one embodiment, step S4-3 specifically includes: recording the number of micro-time units contained in the time period from the start time node to the completion time node of the drawing element as N , and the drawing width of the drawing element is evenly distributed to N micro-time units, and the width of each micro-time unit is

[0038] In this embodiment, the drawing element ​Start and finish time interval , according to the micro-element sequence Reading time interval The number of micro-element included is .Will Decompose according to the average mode and distribute to each micro-element The width is ; Represents a drawing element In each micro-element The minimum width required.

[0039] Traverse all drawing elements and set all width values Combined into a width value matrix :

[0040] Each column corresponds to a micro-element .

[0041] 3. Generate an adaptive time scale for the project progress chart.

[0042] S5, taking the maximum width value of each micro-element as the controlling width of the micro-element, and drawing the time scale of the project progress chart according to the micro-element scale sequence.

[0043] In step S4, it is found that each micro-element has at least one width value. Based on the maximum value of the width differential of the drawing element, the matrix The maximum value of each column , as each micro-element The scale width ensures that the controllable width of all drawing elements can be satisfied, and finally combines the ruler micro-time element sequence Draw a micro-element ruler that adaptively adapts to the width required by each drawing element and realizes an adaptive ruler as the drawing elements are adaptively adjusted.

[0044] In some embodiments, after step S5, that is, after obtaining the width value matrix After that, the step of clustering the micro-element is also included. Specifically, according to the width value of the micro-element, different time granularities are selected to cluster the micro-element. Perform cluster summation to obtain time scales such as day, month, and year.

[0045] Taking a hydropower project as an example, a relational database is used to provide data storage and computing services, and AutoCAD is used for visual drawing. In combination with the accompanying drawings, the technical method of the invention is further specifically described.

[0046] Step 1: Create a scale element time series .

[0047] The project in this example includes 835 processes. The project start and completion dates are January 1, 2024, and March 31, 2038, respectively. The minimum time unit used for the project schedule is day. The project duration interval is sliced ​​by day to obtain a daily time list.

[0048] Draw the number according to the double-code time-scale network diagram, select the time granularity as "year", "month", and "day", store the micro-element in the tree structure of year-month-day, and establish the sequence The micro-element sequence after slicing is shown in Table 1.

[0049] Table 1

[0050] Table 1 shows the continuous slicing results of the start and completion time intervals of the engineering project in the embodiment, wherein the micro-epoch is in days. The slicing results are daily time series, which include the year, month, and day information of the micro-epoch.

[0051] Step 2: Extract control drawing elements from process progress data and create a drawing element set , Contains the start and completion time of the drawing elements and the annotation text content.

[0052] The control drawing elements selected in the double-code network diagram include: the real process of the double-code network diagram and its annotated text; the virtual process of the double-code network diagram and its annotated text; the floating time of the double-code network diagram and its annotated text; the ruler scale and its annotated text.

[0053] According to the set text style and double code style, calculate the control width of the drawing element to form a width set .

[0054] For real processes, virtual processes, floating time, controllable width = radius of double code circle × 2 + safety distance + width of dimension text; Scale control width =safety distance + dimension text width.

[0055] Dimension text width = text height × number of characters / 2 × text aspect ratio; Safety distance = text height × text aspect ratio.

[0056] The text style and double code style given in this example are as follows: The height of the marking text for real processes, virtual processes, and floating time is 2.2, and the aspect ratio is 0.8; the height of the ruler scale text is 1.7, and the aspect ratio is 0.8; the radius of the double-code circle is 0.5.

[0057] Step 3: Read the drawing elements Start and finish time intervals, according to the micro-element sequence Read the micro-element contained in the time interval, and record the number of micro-element as ,Will Decompose according to the average mode and distribute to each micro-element The width is . Traverse all drawing elements and set all width values Combined into a width value matrix In this case the width value matrix It is a 5204×2089 dimensional matrix.

[0058] Step 4: Extract the matrix The maximum value of each column is used as each micro-element The scale width, combined with the scale micro-time element sequence The calculated micro-element scale is shown in Table 2.

[0059] Table 2

[0060] Table 2 is a list of micro-element scales calculated based on the engineering project drawing elements of the embodiment, which records the daily scale width, the start and end positions of the daily time. Table 2 includes the daily scale widths for May, June, and July 2027, and the scale widths for different months are different.

[0061] Step 5: According to the micro-element scale described in step 4, select different time granularities and Cluster summation to obtain time scales of different granularities.

[0062] In this example, in the drawing preferences, only the year and month scales need to be displayed in the drawing. The drawing result is as follows: Figure 3 As shown, Figure 3 Only the time scales for the first five years are shown, including the annual time scale, the engineering month time scale, and the monthly time scale. The annual time scale is obtained by clustering and summing the daily time scales. Figure 1 In the figure, "Year 0" is the ruler folding area. Since there is no process in this year, the ruler scale is controlled by the ruler scale and its labeled text. The ruler width just meets the space required for the monthly labeled text. "Year 1, Month 1" in the figure is the ruler widening area 1. In this area, there is the process "Sidewalk and Construction Preparation". In order to meet the space for drawing the process text, the ruler scale of this month needs to be widened. Figure 1 "October of the 4th year" is the scale widening zone 3. This month is mainly affected by the processes "Pour concrete into the plug" and "Backfill concrete into the plug", and the required text width is larger, so the scale of this month is obviously widened. Figure 1 The process density of "Ruler Widening Area 2" is relatively high, and the widening and folding of the ruler are more complicated, but they can all meet the drawing space required for the drawing elements.
