The calculation formula is: ,in represents the comprehensive index of water quality stability in each monitoring sub-area, and e represents a constant; Step S02: Compare the water quality stability comprehensive index of the normal water quality area with the preset threshold range. Within the preset threshold range, the water quality is judged to be stable. If the water quality stability comprehensive index If it is not within the preset threshold range, the water quality is judged to be unstable and an early warning message is sent to the abnormal result early warning output module.

5. The online detection system for mobile temporary water quality monitoring of a water supply network according to claim 1 is characterized in that: The abnormal result warning output module receives the monitoring sub-area information judged to be abnormal in the water quality judgment model establishment module, sends the first warning information to the human-computer interaction module, receives the monitoring sub-area information judged to be unstable in the water quality stability analysis module, and sends the second warning information to the human-computer interaction module.

6. The online detection system for mobile temporary water quality monitoring of a water supply network according to claim 1, characterized in that: The human-computer interaction module receives the first warning information and the second warning information transmitted by the abnormal result warning output module, and arranges staff to process the warning information.
