Method and device for complementing missing data of water meter

The invention provides a water meter missing data completion method and device, according to different positions of missing data in data transmitted by a water meter, if the missing data is tail data, using a linear interpolation method to determine filling data, and if the missing data is not tail data, using a non-linear interpolation method to determine the filling data. And the missing data in the data transmitted by the water meter is filled by using the filling data to obtain complete data, so that the efficiency and accuracy of obtaining the complete data transmitted by the water meter are improved, and the dependence on historical data is reduced. 本申请提供了一种水表缺失数据的补全方法和装置，根据水表传输的数据中缺失数据的不同位置，如果缺失数据为尾部数据，利用线性插补方法确定填补数据，如果缺失数据不是尾部数据，则利用非线性插补方法确定填补数据，再使用填补数据填补水表传输的数据中的缺失数据，得到完整的数据，提高了得到完整的水表传输数据的效率和准确性，减少了对历史数据的依赖。
