Abstract

The invention relates to the technical field of device time correcting and provides a correcting method and terminal device. The method comprises steps of detecting whether a to-be-corrected terminalis powered off; if detecting that the to-be-corrected terminal is powered off, controlling a power supply system to electrify the to-be-corrected terminal; receiving a self-correcting request sent bythe to-be-corrected terminal after electrification; carrying out interrogation on the clock of the correcting terminal according to the self-correcting request, acquiring the time of the to-be-corrected terminal, and judging whether the time of the to-be-corrected terminal needs to be corrected according to pre-stored standard time and clock time; and if judging that the clock of the to-be-corrected terminal needs to be corrected, correcting the clock of the to-be-corrected terminal. According to the invention, timely timing can be achieved; acquisition success rate is improved and safe and stable operation of the power grid is ensured.

Description

technical field [0001] The invention belongs to the technical field of equipment time calibration, and in particular relates to a terminal time calibration method and terminal equipment. Background technique [0002] At present, the terminal's clock calling and timing strategy is called by the main station to batch test all terminals. If the calling and testing are successful, and the clock deviation is 1-5 minutes, broadcast time synchronization is adopted, and the clock deviation is more than 5 minutes. Point-to-point pairing Time. [0003] The time synchronization frequency of the terminal clock call is once a week, and all terminals with a clock deviation of more than 1 minute are fully timed. The realization of real-time time synchronization will result in a decrease in the acquisition success rate and affect the safe and stable operation of the power grid. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a terminal...
