Water flow data transmission method based on NB-IOT intelligent water meter

The invention relates to the field of data compression and transmission, and provides a water flow data transmission method based on an NB-IOT intelligent water meter, and the method comprises the steps: obtaining historical and current water flow data through a water flow detection module of the intelligent water meter; analyzing the historical water flow data through a data analysis module of the intelligent water meter to obtain a first reference weight of each day so as to obtain a reference fluctuation range of each moment; obtaining a second change degree according to the current data and the reference fluctuation range of each moment and two adjacent moments, obtaining a first abnormal degree according to the difference between the current data and the reference fluctuation range of each moment, and further obtaining the optimal order of each moment; obtaining first trend data of each moment according to the optimal order of each moment, and obtaining segmentation point moments to divide and compress t
