READING SCHEDULING METHOD IN CONSIDERATION OF COMMUNICATION CAPABILITY AND TIME INFORMATION OF METERS

摘要

A meter reading scheduling method considering time information and communication performance of meters of the present invention includes a first step of extracting meters to be measured by a data concentrator (DCU) and acquiring current time information of each of the extracted meters ; A second step of predicting the meterable time of each meter based on the meter reading data generation time of the extracted meters; A third step of correcting the meterable time by reflecting the respective transmission delay time and transmission time according to the communication performance of the extracted meters and the meter reading data size; A fourth step of grouping the extracted meters according to the number of simultaneous processes and correcting the meterable time of the grouped meters; And a fifth step of preparing meter reading scheduling and performing meter reading of the meters according to the meter reading scheduling.
