Description

Technical Field

[0001] The present invention relates to the field of industrial Internet technology, and in particular to a method and system for internal navigation of a factory based on GIS technology. Background Art

[0002] Existing map navigation basically needs to go through several processes, including map data collection, data processing and export, and path calculation. First, map data is constructed, and then path calculation guidance navigation is performed based on the constructed map data. For factories with large areas, their internal roads usually involve sensitive corporate private information. Existing open navigation software has no right to conduct large-scale data collection on their internal roads, and thus cannot further achieve accurate navigation of internal roads. Facing visiting vehicles, it is very difficult to reach the predetermined location inside the factory without the guidance of insiders. Even for internal employees, it is difficult to find the destination inside a large factory. Secondly, the level of factory automation is high nowadays. If the factory has confidentiality requirements, some roads are not allowed to visitors. If the road often transports dangerous goods, visitors and employees should also go there with caution to ensure safety. Finally, there will be construction, temporary stacking of goods, temporary parking of large transport vehicles, etc. on the internal roads of the factory, which will affect the normal driving of the road.

[0003] In view of the above problems, the prior art CN112288818A-UAV rapid shooting modeling method for less than 10,000 square meters proposed modeling through drone aerial photography, optimized the aerial photography path and flight parameters, and could reduce the workload and working time of collection, making the modeling method more convenient. However, it realizes map modeling through drone aerial photography, which has the characteristics of high cost and high technical difficulty. The prior art CN115962782A-Inside and outside park path navigation method and system proposed to realize the integration of park intranet display, query and navigation by integrating park GIS and Internet data, and could perform different navigation for incoming and outgoing freight vehicles. However, it realizes the navigation inside and outside the park through the integration of internal and external navigation data of the park. Although it mentions the customization of different navigation paths for vehicles entering and leaving the park, it does not realize differentiated navigation of different confidentiality levels and security levels, and the navigation path is single, which does not meet the needs of factories with large land area and confidentiality requirements.

[0004] In view of the deficiencies of the prior art, the present invention provides a factory internal navigation method and system based on GIS technology. Summary of the invention

[0005] In order to overcome the above problems or at least partially solve the above problems, the present invention provides a factory internal navigation method and system based on GIS technology, which obtains and marks map parameters, calculates the shortest path for navigation, and provides different navigation paths for users with different identities and different permissions.

[0050] Example:

[0051] like Figure 1 As shown, in a first aspect, an embodiment of the present invention provides a method for internal navigation of a factory area based on GIS technology, comprising the following steps:

[0052] S1. Obtain and generate factory GIS data based on the factory CAD drawings and on-site data collection;

[0053] Furthermore, it includes: importing the factory CAD drawing and field collected data into arcMap to generate the final factory GIS data.

[0054] Furthermore, the method also includes: exporting the factory GIS data processed by arcMap into a Shapefile file, and then importing the Shapefile file into a spatial database PostGreSQL supporting PostGIS components for storage.

[0055] In some embodiments of the present invention, the CAD drawings provided by the factory are used in combination with manual on-site collection, and the CAD drawings and collected data are imported into arcMap, and the relevant data are adjusted to form the final GIS data. The GIS data is imported into the spatial database for use in subsequent steps.

[0056] S2. Obtain and annotate the attributes of the road network data according to the management attribute requirements and the factory GIS data to obtain attribute annotated data; the attribute annotated data includes confidentiality level attributes and security level attributes.

[0057] In some embodiments of the present invention, the management platform obtains the factory GIS data, and displays the complete map information of the factory through front-end technology rendering. The administrator can mark the confidentiality level and security level of the road network information on the map according to the needs. The confidentiality level is divided into: confidential, secret, general by default, and the security registration is divided into: high, medium, and low by default. As shown in Table 1.

[0058] Table 1:

[0059]

[0060] S3, performing visibility control of the road network according to the attribute annotation data to obtain visibility control data;

[0061] Furthermore, the method further comprises the following steps:

[0062] Render the factory GIS data and hide areas with high confidentiality levels.

[0063] In some embodiments of the present invention, the administrator customizes the display or hiding of the road network information corresponding to each confidentiality level and security level according to the needs, as shown in Table 2.

[0064] Table 2:

[0065]

[0066] S4. Obtain and set permissions for different personnel according to management permission requirements to obtain user permissions for corresponding personnel;

[0067] In some embodiments of the present invention, in step 4, the administrator customizes the permissions of departments, employees, visitors, and administrators according to needs, and different permissions can be associated with different confidentiality levels and security levels, as shown in Table 3.

[0068] Table 3:

[0069]

[0070] S5. Obtain and generate a navigation route based on the user's location information, destination information, user authority and visibility control data to achieve internal navigation within the factory.

[0071] Furthermore, it also includes: real-time monitoring of the walking routes of users with different permissions, if a user with low permissions appears in an area with a high confidentiality level, an alarm message is immediately generated and sent.

[0072] In some embodiments of the present invention, the user logs in to the navigation system, and the map automatically displays the user's current location. According to the visibility settings and user permissions, the road network with a high confidentiality level is hidden, the hidden area is grayed out, and no information such as roads and buildings is displayed. The user enters the destination, and the best navigation route is calculated according to the current user permissions. The user goes according to the navigation route. If the route is deviated during the process, a prompt will be given. If the user is about to enter an area with a high confidentiality level, the user will be prompted that the behavior will trigger an alarm mechanism, please proceed with caution. If the user is about to enter an area with a low security level, the user will be prompted that there is a source of danger in the area, please proceed with caution. When a user with low permissions enters a road or area with a high confidentiality level, the alarm mechanism will be triggered, and the alarm message will be sent to the administrator via SMS, WeChat, and management platform. The administrator can click on the link in the alarm message to enter the map, which shows the distribution of all cameras in the factory. The administrator clicks on the camera mark near the alarm location to call out the camera and view the real-time situation. As shown in Table 4.

[0073] Table 4:

[0074]

[0075] This method generates basic map data based on the factory CAD drawing; sets the confidentiality level and security level of the road network by marking the attributes of the road network data; and calculates the navigation route that best suits the current user based on the authority of the current user and the level of the road network data, using algorithms such as the weighted shortest path. Dangerous marks are placed on some construction roads, and the road safety level is updated to prompt users to proceed with caution. The present invention provides a privatized data editing platform for the sensitive and non-disclosed nature of internal factory roads, and the data is maintained and updated independently by the enterprise to avoid being mastered by outsiders. At the same time, according to the set map security level and user authority, roads with low security levels are avoided during navigation, and users can view the safety level of the road on the map. The present invention is based on navigation based on the acquisition and annotation of map parameters, and the calculation of the shortest path to provide different navigation paths for users with different identities and different authorities.

[0076] Based on the first aspect, further, the internal navigation method of the factory based on GIS technology also includes the following steps:

[0077] Obtain and modify factory GIS data based on administrator modification requests.

[0078] In some embodiments of the present invention, an open editing module for maps is provided, allowing administrators to edit map data independently. Relying on arcMap, select the elements to be edited (e.g., point elements, line elements, and surface elements) on the visual map, and move, delete, add, or modify the attributes of the elements. After editing, you can preview it. If the preview effect does not meet your expectations, you can continue editing. Finally, click Save to update the map data. Figure 4 shown.
