The acquisition device 101 can acquire data according to different scenes, different times, different places and the like, the database 102 stores the data acquired by the acquisition device 101, and the electronic device 103 communicates with the database 102 through a network to acquire the acquired data stored in the database and generate a corresponding Gantt chart.
The electronic device 102 may be various types of devices with information processing capabilities, such as a navigator, a smart phone, a tablet computer, a wearable device, a laptop portable computer, a kiosk and a desktop computer, a server cluster, and the like.
Based on this, the embodiments of the present application provide a method for generating a gantt chart, where the method is applied to an electronic device, and functions implemented by the method may be implemented by a processor in the electronic device calling a program code, and of course, the program code may be stored in a storage medium of the electronic device. Fig. 1B is a first schematic flow chart of an implementation process of a generation method of a gantt chart in an embodiment of the present application, as shown in fig. 1B, the method includes:
s101, acquiring at least one item to be processed; each of the pending items comprises at least one activity, each of the activities comprises a plurality of execution time periods;
here, the gantt chart is also called as a crosswalk chart or a bar chart. It shows through bar graphs how items, progress and other time-dependent internal relationships of system progress over time. The items to be processed comprise at least one activity, and each activity comprises a plurality of execution time periods. For example, in the "vehicle management" project, the capturing device at the entrance/exit of a parking lot is turned on from 6 to 8, turned off from 8 to 12, and turned on from 12 to 1, and the execution time period of the video source captured by the capturing device includes the time period from 6 to 8 and the time period from 12 to 1.
In the embodiment of the present application, a plurality of items to be processed may be rendered in one gantt chart, and when the items to be processed include a plurality of activities, an association relationship may exist between the plurality of activities, or each of the activities may be an independent activity.
Step S102, aiming at each activity, matching a horizontal axis with rendered time scales with each execution time period to obtain an icon to be rendered corresponding to each execution time period;
for example, the current time and the time 24 hours ago may be determined, cut into 24 segments, and rendered on the X-axis. And then circulating a plurality of activities under the project to be processed, acquiring a certain execution time period of a certain activity, matching the time scale of the rendered X axis according to the starting and ending time of the execution time period, dynamically rendering a horizontal bar for identifying resource occupation after the matching is finished, and rendering the horizontal bar for representing all activities and resource occupation conditions of all execution time periods under each activity after multiple circulation.
That is to say, after the matching is completed, the icon to be rendered corresponding to each execution time period is obtained, and then the bar representing the resource occupation situation is obtained after the icon to be rendered is rendered.
Step S103, rendering the icon to be rendered based on the position of each activity on the vertical axis, the starting and ending time of each execution time period and the time scale of the horizontal axis to obtain the Gantt chart of the at least one item to be processed.
Here, according to the position of each activity on the vertical axis, the position of the icon to be rendered corresponding to each execution time period in the activity on the vertical axis can be obtained. According to the starting and ending time of each execution time period and the time scale of the horizontal axis, the position of the icon to be rendered corresponding to each execution time period in the activity on the horizontal axis can be obtained. Furthermore, the icon to be rendered corresponding to each execution time period in the activity can be rendered at the position corresponding to the Gantt chart. Therefore, the Gantt chart component can show resource occupation conditions of multiple projects, multiple activities and multiple time periods of a single activity, and can be used for expressing services of any time occupation condition according to an actual application scene.
In some embodiments, where the activity comprises a video source, the method further comprises:
step S11a, analyzing the video content of each execution time slot in the video source to obtain a corresponding analysis result;
step S12a, determining the style parameter of the icon to be rendered corresponding to each execution time period according to the analysis result; wherein, different analysis results correspond to different style parameters.
In some embodiments, where the activity comprises a video source and the generation of the gantt chart is complete, the method further comprises:
step S11b, responding to the cursor floating on the rendered icon of the Gantt chart, and displaying the description information of the video content corresponding to the rendered icon; wherein the description information includes at least one of: a brief introduction of the video content, an alert of the video content;
and step S12b, responding to the selected operation of the rendered icon, and displaying the video content corresponding to the rendered icon.
Based on the foregoing embodiment, an embodiment of the present application further provides a method for generating a gantt chart, where the method is applied to an electronic device, and the method includes:
s111, acquiring at least one item to be processed; each of the pending items comprises at least one activity, each of the activities comprises a plurality of execution time periods;
step S112, aiming at each activity, matching a horizontal axis with rendered time scales with each execution time period to obtain an icon to be rendered corresponding to each execution time period;
s113, acquiring a style parameter of the icon to be rendered;
here, the style parameter may be customized by a user or an operation and maintenance person, that is, the user or the operation and maintenance person may customize various style parameters according to an actual use situation. For example, the style of the gantt chart, such as the length of the gantt chart, the width and the transparency of the gantt chart, the style of the bar corresponding to each execution time period, such as the color and the transparency of the bar, and the style of each item or each activity in the vertical axis, such as different colors of different types of activities, may be customized.
Step S114, obtaining the position of each execution time period on the horizontal axis according to the starting and ending time of each execution time period and the time scale of the horizontal axis;
in the embodiment of the present application, the starting time and the ending time of each execution time period are the starting time and the ending time of each execution time period. For example, an activity is in the executive state at 8 to 10, in the halt state at 10 to 18, in the executive state at 18 to 24, and in the halt state at 0 to 8. Then one execution period in the campaign has a start time of 8 and an end time of 10, and another execution period has a start time of 18 and an end time of 24. Further, the position of each execution time period on the horizontal axis can be obtained according to the start time and the end time of each execution time period and the time scale of the horizontal axis. For example, when the current time and the time before 24 hours are divided into 24 segments, the rendering X-axis shows that the starting time of a certain execution time segment is 10 points, the ending time is 11 points, the starting point of the horizontal bar corresponding to the execution time segment is 10/24 points, the ending point is 11/24 points, and the width is (11-10)/24 points.
Step S115, determining the position of each execution time period on the vertical axis according to the position of each video source on the vertical axis;
here, the position of each video source on the vertical axis, i.e., the position of each of the execution periods in the video source on the vertical axis.
And step S116, rendering the icon to be rendered by utilizing a cascading style sheet based on the positions of the execution time periods on the horizontal axis and the vertical axis respectively and the style parameters of the icon to be rendered to obtain the Gantt chart of the at least one item to be processed.
Here, the cascading style sheet is a computer language used for expressing a file style such as HTML (an application of standard universal markup language) or XML (a subset of standard universal markup language), and the cascading style sheet can precisely control the layout of element positions in a web page at a pixel level, support almost all font and font styles, and have the capability of editing web page objects and model styles. Therefore, in the embodiment of the application, based on the customized style parameter, the position (coordinates where the horizontal axis and the vertical axis are located) of each execution time period is rendered by using the cascading style sheet, so that a rendered icon corresponding to each execution time period of each activity is obtained, and further, a gantt chart of the to-be-processed item is obtained. For example, an inline style (inline style) may be set, changing the style, according to the incoming parameters.
Based on the foregoing embodiment, an embodiment of the present application further provides a method for generating a gantt chart, where the method is applied to an electronic device, fig. 2 is a schematic view of an implementation flow of the method for generating a gantt chart according to the embodiment of the present application, and as shown in fig. 2, the method includes:

here, the style parameter of the gantt chart refers to a style parameter of a chart display region, which refers to the entire gantt chart, and the style parameter of the gantt chart may be a length, a width, a transparency, and the like of the gantt chart in the entire page. For example, the region in which the entire gantt chart in fig. 4 is located is a chart display region. The style parameter of the icon to be rendered refers to the style parameter of the rendered icon corresponding to each execution time period of each activity, for example, the style parameters of the bar 43 and other bars in fig. 4. The style parameter of the item refers to a style parameter corresponding to each item in the vertical axis, such as the style parameter of the item "vehicle management" in the Y axis 42 in fig. 4, and the style parameter of each activity (including video source) under the item "vehicle management". For example, the horizontal axis in fig. 4 is the time starting point, i.e., the zero point.

And S206, rendering the icon to be rendered based on the position of each activity on the vertical axis, the starting and ending time of each execution time period and the time scale of the horizontal axis to obtain the Gantt chart of the at least one item to be processed.
Here, the precise position of the icon to be rendered in the gantt chart can be determined by the position of each activity on the vertical axis, the starting and ending time of each execution time period, and the time scale of the horizontal axis, and the icon to be rendered is rendered by using the cascading style sheet.

step S335, analyzing the video content of each execution time slot in the target video source to obtain a corresponding analysis result;
for example, the video content of each execution time period of a video source under a certain project is analyzed, and the obtained analysis result is a statistical result of event detection in each execution time period.
Step S336, determining the style parameter of the icon to be rendered corresponding to each execution time period according to the analysis result; wherein, different analysis results correspond to different style parameters;
for example, if the called target video source is a video source under a vehicle management project, and the video source is used for managing the vehicle access situation, the video content of each execution time period of the video source may be analyzed, and the obtained analysis result is statistics of the vehicle access situation in each execution time period. If the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is larger than a first preset threshold value, rendering the icon to be rendered corresponding to the time period to be red; if the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is smaller than a second preset threshold value, rendering the icon to be rendered corresponding to the time period to be green; and if the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is between a second preset threshold value and the first threshold value, rendering the icon to be rendered corresponding to the time period to be yellow.

If the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is larger than a first preset threshold value, rendering the icon to be rendered corresponding to the time period to be red; if the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is smaller than a second preset threshold value, rendering the icon to be rendered corresponding to the time period to be green; and if the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is between a second preset threshold value and the first threshold value, rendering the icon to be rendered corresponding to the time period to be yellow. When the mouse is moved to a yellow rendered icon (horizontal bar), the system pops up alarm information, and the content of the alarm information is as follows: "the vehicle of entering is more than the vehicle of leaving in this time quantum, and the vacant parking stall remains inadequately".
And step S339, responding to the selection operation of the rendered icon, and displaying the video content corresponding to the rendered icon.
Here, the operation of selecting the rendered icon may be detecting that a user clicks a certain rendered icon.

If the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is larger than a first preset threshold value, rendering the icon to be rendered corresponding to the time period to be red; if the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is smaller than a second preset threshold value, rendering the icon to be rendered corresponding to the time period to be green; and if the difference value of the number of the vehicles entering the parking lot and the number of the vehicles leaving the parking lot is between a second preset threshold value and the first threshold value, rendering the icon to be rendered corresponding to the time period to be yellow. Clicking on the rendered icon for yellow, the system pops up the vehicle access video clip for that time period.
Based on the foregoing embodiment, in order to intuitively and beautifully show the occupation situation of video resources and quickly understand the problem of which video resources are occupied in any time period, the embodiment of the present application further provides a method for generating a gantt chart, that is, a gantt chart component in the embodiment of the present application is developed by using technologies such as HTML5 (a language description mode), CSS (Cascading Style Sheets), JS (JavaScript, a programming language), and the like.

1) by extracting the custom parameters, the latest 24 hours can be automatically rendered as X-axis coordinates, and the X-axis can intelligently render a dividing line, so that data can be displayed more intuitively and friendly.
Here, a parameter may be defined at the entry file of the code, for example, the parameter may be a width value (width of the entire gantt chart), which may be one-half, one-third of the screen; the parameter can also be the starting point of time, and the later Gantt chart can be set to be in the unit of days or hours; the parameter may also be color. The Gantt chart component provided by the embodiment of the application can intelligently render a vertical time partition line.
2) Any region such as an X axis (horizontal axis), a Y axis (vertical axis), each video source display region and a chart display region supports customization of any style by dynamically changing the CSS, and the problem that the style of an open source library is difficult to freely modify is solved.
In the embodiment of the application, the CSS can be dynamically changed through the java script language, so that the customization of any style is realized. Here, the area where the whole gantt chart is located is a chart display area, and the area where the icon (i.e., the bar) corresponding to each execution time period of the video source is located is a video source display area.
3) The data interface is optimized, multi-video source display is supported, multi-time-period display of a single video source is supported, and the occupation condition of video resources is expressed more intuitively and easily.
Here, the back-end provides a data interface that functions to inform the front-end which video sources occupy which time periods. The interface can provide various services, a plurality of videos under each service, a plurality of occupied time periods of each video and the like.
In detail, the generation method of the gantt chart can be realized by the following steps:
step S401, acquiring video content, starting time or ending time of video services such as area management, night patrol management, vehicle management and the like in the using process;
s402, according to the video types, a plurality of time periods of each type, starting ending time of each time period and other fields, storing the fields in a database in a structured manner;
and S403, acquiring data in the background database, receiving the data by the front-end Gantt chart component, rendering the Gantt chart in real time according to the data, and visually displaying the resource occupation condition of various video sources in any time period.
For example, the front end receives data of the back end through HTTP (Hyper Text Transfer Protocol), and then inputs the data into the component.
Wherein the step S403 can be implemented by:
step S4031, obtaining the current time and the time before 24 hours, cutting the current time and the time before 24 hours into 24 sections, and rendering an X axis;
s4032, circulating a plurality of video sources, acquiring a certain occupied time period of a certain video source, matching a time scale of an X axis rendered before according to the starting and ending time, dynamically rendering a horizontal bar for identifying resource occupation after data calculation, and rendering a horizontal bar for representing all the video sources and resource occupation conditions of all the time periods of each video source after multiple circulation;
here, the loop refers to sequential rendering of a plurality of video sources and a plurality of time periods for each video source.
Step S4033, according to the types of the video sources, the occupied horizontal bars of each video source alternately adopt different colors to improve the discrimination, and the Y axis renders different styles according to different types of the video sources;
and step S4034, parameters such as length, width, height, color and transparency are extracted, so that the free customization of the style of the Gantt chart is supported.
Fig. 4 is a schematic diagram of a gantt chart generated in an embodiment of the present application, as shown in fig. 4, a starting time point of an X axis 41 of the gantt chart is a zero point, services (i.e., items) included in the gantt chart include "vehicle management" and "traffic management", and the like, wherein the "vehicle management" service includes two video sources (i.e., activities) and the two video sources are independent video sources, and the "traffic management" service includes one video source. It can be seen that the names of the different services, and the names of the different video sources under each service, are rendered in the Y-axis 42. Correspondingly, the video source display area under the X-axis 41 renders a plurality of video sources and a plurality of time periods of each video source, wherein the bar 43 is a rendering result of an occupied time period of the video source "first major" under "traffic management".
Compared with the problems that the Gantt chart component in the related art is difficult to modify in style and is not intuitive and unfriendly to display, the Gantt chart component in the embodiment of the application can freely customize the display style; compared with the prior art that the resource occupation situation of multiple time periods is difficult to show by the Gantt chart component, the Gantt chart component in the embodiment of the application can show the resource occupation situation of multiple video sources and multiple time periods of a single video source. Thus, the generation method of the gantt chart in the embodiment of the application can achieve the following technical effects:
1) according to the actual application scene, the display style can be freely customized.
