In recent years, the state has paid increasing attention to issues such as the construction of urban underground pipe networks. However, there is currently no good pipeline detection and analysis software to provide auxiliary decision-making support for the construction of urban underground pipe networks:

[0003] Most existing pipeline detection and analysis software is of the C / S architecture, with a narrow application range, high requirements for the deployment environment, high maintenance costs, and inconvenient upgrades; some pipeline detection and analysis software of the B / S architecture generally has problems such as inaccurate detection results or low analysis efficiency; most existing pipeline detection and analysis software is for the detection and analysis of one or several types of pipelines, which is not comprehensive; the CIM pipeline detection and analysis method based on WisemapGisServer proposes a solution for the above-mentioned status quo, and its advantages are as follows:

[0004] Adopting the B / S architecture, only a browser is required without installing any special software, without installation and maintenance costs, solving the problems of high requirements for the deployment environment, inconvenient maintenance and upgrades of traditional C / S architecture pipeline detection and analysis software.

[0005] Targeted optimization is carried out for the characteristics of WisemapGisServer, and the analysis efficiency is significantly improved on the premise of ensuring the accuracy of detection results.

[0006] Detection types such as pipeline collision detection, vertical clearance detection, horizontal clearance detection, burial depth detection, comprehensive detection, etc., and analysis types such as cross-section analysis, longitudinal section analysis, flow direction analysis, connectivity analysis, burst pipe analysis, etc. are provided, and the export of detection and analysis results is supported.

[0007] A reference plan for moving non-compliant pipelines to suitable construction positions is provided, and the feasibility of the plan is relatively high.

[0008] For the pipeline detection and analysis under the existing WisemapGisServer, collision detection, vertical clearance detection, horizontal clearance detection, burial depth detection, etc. are carried out one by one between the selected pipeline and all pipelines in the map, and the detection standards are compared, and finally the detection and analysis results are obtained.
