Method and device for monitoring external water intrusion analysis in real time based on sewage pipe network

The invention relates to the technical field of water quality prediction, and discloses an analysis method for monitoring external water intrusion in real time based on a sewage pipe network. Acquiring basic data information; dividing the pump station service area into a plurality of diagnosis subareas according to the pipe network data information and the pump station service area data information, and determining a first monitoring point position; acquiring first monitoring data at the first monitoring point position, and dividing the first monitoring data into a rainfall period data set and a non-rainfall period data set; carrying out statistical information calculation, and carrying out data preliminary judgment according to a statistical information calculation result to generate an abnormal monitoring point; a second monitoring point position is arranged at the abnormal monitoring point, data information of the second monitoring point position is obtained, and external water intrusion amount information
