Description

Technical Field

[0001] The present invention relates to the technical field of underground pipe corridors, and in particular to an intelligent control system for an urban underground comprehensive pipe corridor. Background Art

[0002] On both sides of the highway, we can see a large number of exposed cables, which not only pose a great threat to personal safety, but also greatly damage the beauty of the entire city. The continuous construction of urban integrated pipeline corridors can facilitate urban management and urban pipeline management, cope with repeated road excavation, solve problems such as frequent dangerous accidents in pipelines and lines, and promote urban development into a safe, beautiful, efficient and centralized modern city.

[0003] However, during the operation and maintenance of urban underground comprehensive pipelines, various potential risk factors interact with each other, making the safety status in the operation and maintenance process present a multi-factor coupling characteristic. Among them, in actual use, urban underground comprehensive pipelines are affected by homogeneous risks and heterogeneous wind risks. The air humidity in urban underground comprehensive pipelines is high and the corrosiveness is strong. According to actual operating experience, the service life of conventional protection level equipment in the pipeline corridor environment will be significantly shortened. In addition, the pipeline corridor is arranged underground. When harmful gases leak in the pipeline corridor, it is difficult for operation and maintenance personnel to discover it in time, resulting in the leakage of harmful gases into the air and mixing with the air, thereby causing harm to the health of residents.
