Description

Technical Field

[0001] The present invention relates to the technical field of traffic data collection, and in particular to a method and system for collecting and mapping traffic data based on a mobile GIS platform. Background Art

[0002] GIS platform, full name of geographic information system platform, is a technical system that integrates spatial data management, analysis and visualization. It can be used to integrate collected multi-dimensional data and store, analyze and dynamically update it. In addition, the application field of GIS platform is relatively wide. For example, when used in the field of mineral resources, it can realize the boundary circle of coalfield burn areas and intelligent management of mines; when used in the field of transportation, it can collect traffic data for real-time monitoring of traffic conditions.

[0003] Under the traditional model, when collecting traffic data, personnel are usually required to set up work sites on site. The information collected at the work sites is saved on site through paper records or sketch marks, and the data is later manually entered into the system. This method is not only inefficient, but also prone to data errors, which in turn affect the judgment of traffic conditions. In addition, since the data at the work sites is collected first and then entered, the data has a delay and is not very timely.

[0004] In response to the above problems, a traffic data collection and mapping method and system based on mobile GIS platform is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a method and system for collecting and mapping traffic data based on a mobile GIS platform. By adopting this device, the problems of low data collection efficiency and easy occurrence of data errors in the above-mentioned background, which affect the judgment of traffic conditions, are solved. In addition, the problem of data at the work site being collected first and then entered, resulting in data delay and lack of timeliness, is solved.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a traffic data collection and mapping system based on a mobile GIS platform, comprising an architecture design module and a system function module, wherein the architecture design module includes the overall system structure and the overall system technical route, and the system function module includes a homepage, projects, and configuration; The overall structure of the system is as follows: The system adopts the MVC architecture, directly controls the View internally, and separates the network module, database management module, file management module and common tool classes into several tool class packages for use by Activity and Fragment; The overall technical route of the system is as follows: The communication data is transmitted to the communication server through the data interface, and the mission data and GPS positioning data are transmitted to the command management server through the data interface.

[0009] Furthermore, the specific contents of adding work points are as follows: The information of the work point includes the name and longitude and latitude. According to the current time, a marking point is generated with the center of the screen as the coordinate and displayed on the current map in the form of an icon to complete the addition of the work point. The above-mentioned marking point is the work point.

[0010] Furthermore, the specific content of drawing the graphics is as follows: Click the screen to trigger drawing points. After drawing two points, the line between the two points will serve as the diagonal of the drawn rectangle. After drawing three points, a closed triangle will be formed based on the three points. After drawing four or more points, line segments can be generated according to the order of the points and closed into a polygon.

[0011] Furthermore, the specific contents of drawing the trajectory are as follows: Clicking on the page triggers the drawing point and displays the track length. Multiple tracks can be drawn by adding drawing points in sequence.

[0012] Furthermore, the specific contents of ranging and azimuth are as follows: Click the page screen to select the distance and azimuth button, and click the page screen again to trigger the point drawing. After drawing two points, the line between the two points is used as the drawn track, and the track length, line segment ruler, and azimuth of adjacent line segments are displayed.

[0013] Furthermore, the specific contents of the real-time trajectory are recorded as follows: Click the track record button on the screen to start recording the track. The track record follows the movement of the device to record the track line. It is turned on in the background by default, and users can choose to turn it on and off during configuration.
