Description

Technical Field

[0001] The present invention relates to the field of digital management technology, and in particular to a digital management system for drainage network operation and maintenance data. Background Art

[0002] With the continuous acceleration of urbanization, the number and scale of drainage networks are also growing. In order to ensure the normal operation of urban drainage, the maintenance and management of drainage networks are becoming more and more important. However, there are many problems with traditional drainage network maintenance and management methods, such as inaccurate information records and low work efficiency of managers. These problems seriously affect the safe operation of drainage networks and the sustainable development of cities. Therefore, it is necessary to develop a system that can realize digital management of drainage network operation and maintenance data, thereby improving the management efficiency and safety of drainage networks.

[0003] After searching, the invention patent with Chinese publication number CN116050037A discloses an indirect monitoring and analysis method for the liquid level of an urban drainage system based on a directed topological network, which includes the following steps: constructing a directed topological model of the drainage network and a drainage network database; extracting the upstream and downstream inspection wells and pipeline numbers corresponding to the monitoring points; preliminarily estimating the liquid level; dividing the network into upstream, mid-upstream and downstream areas; calculating the new liquid level for each node and pipeline in the mid-upstream and downstream areas of the monitoring point; and adjusting the areas where the liquid level difference between the two ends of the pipeline is too large. The present invention is based on an urban drainage system with a directed topological network. In combination with the monitoring values ​​obtained by actual monitoring equipment, the invention indirectly monitors the liquid level of other pipe networks through pipe network initialization interpolation and subsequent smoothing processing, assisting the pipe network operation and maintenance unit to grasp the real-time liquid level changes of the entire drainage system from a global perspective at a limited monitoring cost, and providing effective data support for the operation and maintenance management of the urban drainage network and scientific scheduling decision-making.

[0004] Compared with the existing technology, the invention patent with Chinese publication number CN116050037A divides the drainage network into regions and analyzes and processes the pipelines in different areas based on the regional division results, thereby achieving the effect of indirect monitoring;

[0005] However, in the actual use of the above system, the drainage network is not clearly divided and has a wide span during the drainage process, which makes it impossible to accurately coordinate, resulting in a small range of coordination, thus affecting the coordination results. Therefore, how to set the corresponding scientific drainage network flow, effectively coordinate the drainage flow direction in different areas within the maximum range, and improve the coordination in the drainage process is a problem we need to consider. To this end, a digital management system for drainage network operation and maintenance data is proposed. Summary of the Invention
