Description
Technical Field
The present invention relates to the field of terminal clock calibration technologies, and in particular, to an intelligent terminal clock management method and apparatus, a storage medium, and a terminal device.
Background
In an electric power system, the clock calibration of the station has extremely important significance for network frame topology analysis, line loss analysis and electricity charge statistics. The method for calibrating the clock of the intelligent terminal mainly comprises several methods of metering master station broadcasting timing, terminal initiative request, satellite timing, communication base station timing and the like, and the application of the methods has the respective defects that: the first method for broadcasting time synchronization by the metering master station is that the metering master station broadcasts time signals to all the station areas in the areas in a broadcasting mode, the station areas receive the broadcasting signals to finish clock time synchronization, the metering master station in the time synchronization mode only transmits time synchronization broadcasting once a day, but restarting the metering master station after breakdown can lead to time disorder, if the time synchronization of the metering master station is restarted, the terminal time is inaccurate, namely, when the time of the intelligent terminal is inconsistent with the time of the metering master station, the intelligent terminal can only calibrate after the metering master station transmits time synchronization broadcasting the next day, and therefore, the intelligent terminal is poorer in Zhong Shishi accuracy by means of the time synchronization mode of the metering master station broadcasting. The second type of intelligent terminal actively requests time setting mode mainly depends on the private network to request time setting to the metering master station, but the private network bears other high-capacity data transmission tasks between the intelligent terminal and the metering master station, the data transmission pressure is large, if the intelligent terminal frequently requests time setting, the private network transmission pressure is further increased, timely time setting cannot be completed, and therefore the intelligent terminal actively requests time setting is not easy to frequently, and real-time accuracy of an intelligent terminal clock is not guaranteed. The third method adopts a satellite time setting method, which mainly relies on an intelligent terminal time setting chip and a satellite to finish time setting calibration, but the time setting process needs to be finished outdoors, and the satellite clock may have the risk of being tampered, so that the satellite time setting cannot ensure the accuracy of the time setting clock, and the time setting can only be finished outdoors with limitation. The fourth method for setting time of the communication base station mainly means that the intelligent terminal and the signal base stations of communication operators such as mobile, communication and telecom are set time, but the clocks of the communication base station are not necessarily consistent with the clocks of the metering master station, and if the clocks of the intelligent terminal and the clocks of the metering master station deviate, the clocks of the intelligent terminal and the clocks of the metering master station are not synchronized. Therefore, each time setting method cannot ensure that clocks of a terminal and a master station are kept consistent accurately, calibration cannot be timely obtained when the clocks of the terminal are deviated, and when the functions of the clock of the terminal have an outgoing line fault, the clock of the terminal cannot be normally processed under the condition that the clock of the terminal cannot be normally set at non-time setting time, so that the clock of the terminal is incorrect.
According to the method, the existing intelligent terminal and the metering master station cannot frequently time, and the satellite clock and the base station clock are inconsistent in the master station clock, so that the clock of the intelligent terminal is inaccurate and cannot be checked in time, and the clock problem of the intelligent terminal cannot be found in time, so that the intelligent terminal with problems cannot be maintained and processed in time.

When the clock of the intelligent terminal meets constraint conditions, it is indicated that the running time of the intelligent terminal is abnormal, and the intelligent terminal is marked, so that the intelligent terminal can be maintained and managed in time later.
It should be noted that, the deviation threshold and the frequency threshold may be set according to the requirement of the management intelligent terminal, for example, the deviation threshold may be 0.05, and the frequency threshold may be 10.
