Urban drainage pipe network operation and maintenance method based on pipe network construction model and Internet of Things

The invention discloses an urban drainage pipe network operation and maintenance method based on a pipe network construction model and the Internet of Things. The method comprises the following stepsof: collecting urban drainage pipe network information; establishing the BIM model of the urban drainage network based on a BIM technology; establishing a B/S, M/S pipe network operation and maintenance platform based on a GIS technology; arranging the internet-of-Things intelligent sensing equipment at the front end of the pipe network through calculation of a pipeline hydraulic model so as to sense pipe network operation information; carrying out lightweight processing on the BIM model, uploading the BIM model to the B/S, M/S pipe network operation and maintenance platform, and superposing the BIM model into a GIS map; enabling the data obtained by the Internet-of-Things intelligent sensing equipment to be in one-to-one correspondence with the BIM model and the GIS map, and achieving thesharing and transmission
