A mobile terminal-based time correction control method, system and mobile terminal

Abstract

The invention discloses a time correction control method, system and mobile terminal based on a mobile terminal. The method detects the value of the counter every set time by starting the timer, and compares the value of the counter with the size of the set threshold ;When the value of the counter is greater than the set threshold, obtain the current time as K; reset the value of the counter and correspond to the current time K. When the value of the counter is accidentally modified due to factors such as static electricity in the environment, magnetic field, drop or chip quality problems, it can effectively avoid the secondary time display error caused by the overflow of the counter, and improve the accuracy of time display, which is convenient for users. use.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a mobile terminal-based time correction control method, system and mobile terminal. Background technique [0002] In addition to the basic communication functions, the mobile terminal is also regarded as an electronic tool for checking the time by many users because of its accurate timekeeping and clear display; in the prior art, the time of the mobile terminal is based on its counter. The clock counts and then adds an accurate base time to get the current time, as follows: [0003] When the mobile terminal corrects the time, the value of the counter is P1, and the current time to be corrected is K1; after the correction is completed, the counter P1 will add 1 in each main clock cycle of the mobile terminal, and the main clock cycle is set as T1, then when the counter When the value of is P2, the time K2 of the mobile terminal should be: [0004] K2=K1+(P2-P1)*T1.

AI Technical Summary

Problems solved by technology

[0005] At present, the counters in mobile terminals are often absolutely sufficient, and generally counting from zero can be used for hundreds of years; however, due to the portability of mobile terminals, mobile terminals are inevitably affected by static electricity, magnetic fields, drops or chip quality problems and other factors accidentally cause the value of the counter to be modified; when the value of the counter is accidentally modified, the first thing that occurs is that the time of the mobile terminal is incorrect. When the value is accidentally modified to a value close to overflow, when the user corrects the time through the network or manually for a certain period of time (maybe very short, such as one hour, or may be long, such as five years), the secondary display error of the time will be caused by the overflow of the counter, giving Things that bother users and even delay users

[0006] That is, in the prior art, for example, the value of the counter is accidentally modified to P3 due to factors such as static electricity in the environment, magnetic field, drop or chip quality problems, and P3 is very close to the maximum value P4 of the counter; when the user finds that the time is incorrect, Correct the time through the network or manually, but after a period of time, the value of the counter will reach the maximum value P4 and then the counter will become zero after overflow; at this time, because the value of the counter becomes zero, it will cause a time display error again, which will bring users Things that bother and even delay users
