Abstract:In order to improve the accuracy of short-term prediction of low voltage carrier meter reading delay, so as to improve the quality of automatic meter reading system communication condition fault prevention work, put forward a prediction method of narrowband carrier meter reading delay average multiple linear regression method based on least squares according to close fitting principle, with the square of the residual and the most Small as the goal to establish the calculation model of the value of regression coefficient estimates. Error to pilot low area to compare the actual measured value and predicted results, verify the feasibility of the method.
