Description

Technical Field

[0001] The present invention relates to the technical field of geographic information systems, and more particularly to a GIS-based urban pipe network management system and method. Background Art

[0002] With the rapid development of urban infrastructure construction, people's demand for urban pipe network systems in daily life is also increasing. The role of various types of pipe networks, including water supply, drainage, gas, and heat, in daily life is becoming more and more important. They play an important role in ensuring the safety of urban water supply and drainage, improving resource utilization efficiency, and promoting urban sustainable development. Therefore, the development of a GIS-based urban pipe network management system and method is of great significance for realizing the intelligent and information-based management of urban pipe networks.

[0003] The traditional urban pipe network management system includes a data acquisition module, a data processing and analysis module, a monitoring center module, and an alarm and emergency handling module. Among them, the data acquisition module collects various data of the urban pipe network system through sensors and instrument equipment to ensure the accuracy of the data; the data processing and analysis module cleans, converts, integrates and processes the collected data to form a unified data format and uses data analysis technology to conduct in-depth mining of the pipe network data, providing information on pipe network operation status analysis, fault warning, and energy consumption analysis, and providing data support for management decisions; the monitoring center module is responsible for receiving, storing, displaying and analyzing processed data, and displaying the operation status of the pipe network system in a visual way to help managers fully understand the situation of the pipe network system; the alarm and emergency handling module will automatically trigger the alarm mechanism and notify relevant personnel when an abnormal situation occurs in the pipe network system, and at the same time provide emergency handling plans and suggestions to assist managers in responding and handling problems quickly.

[0004] However, in actual use, it still has some shortcomings, such as inaccurate data collection. The data acquisition module collects various data of the urban pipe network system through sensors at regular intervals, but does not collect data in real time, resulting in inaccurate system data collection; incomplete data collection. During data collection, only the data collected by the sensors is collected, and the universal data exchange format of three-dimensional spatial geographic coordinates is not considered, and real-time changes to municipal pipeline facilities cannot be achieved; there is a lack of human-computer interaction. The system only displays the operating status of the pipe network system, and relies entirely on data analysis and processing technology to process the pipe network system. It cannot provide an interactive interface for equipment parameter setting and layout adjustment operations.

[0005] Therefore, there is an urgent need to provide a GIS-based urban pipe network management system and method to solve the problems of incomplete data collection, insufficient data accuracy, and drone interaction in existing urban pipe network management systems. Summary of the Invention
