Accurate punctuality algorithm of fusion terminal

An intelligent fusion terminal serves as an edge in a cloud management edge end architecture of an intelligent power grid Internet of Things system, has the functions of information collection, edge calculation, equipment perception and the like, and plays a significant role in information collection and gathering in an intelligent power grid; the related technical specifications of intelligent fusion terminals in courts require that the terminal punctuality precision error should meet 0.5 s/d, so that research on accurate clock information input is of great significance. In the clock reading and calibration process, multiple times of sampling are innovatively provided, interval samples are used for calculating the average error, in the algorithm, random errors are diluted, corrected and subjected to error compensation, the occurrence probability of peak errors is reduced, and the timekeeping performance of the system is guaranteed. According to the invention, the innovative development of software is carried
