Description
Technical Field
The invention relates to the field of mobile terminals, in particular to a time correction control method and system based on a mobile terminal and the mobile terminal.
Background
Besides the basic communication function, the mobile terminal is also regarded as an electronic tool for viewing time by many users because the time is accurately timed and clearly displayed; in the prior art, the time of the mobile terminal is obtained by counting a main clock of the mobile terminal according to a counter of the mobile terminal and then adding an accurate basic time, and the specific steps are as follows:
when the mobile terminal corrects the time, the value of the counter is P1, and the time to be corrected is K1; after the calibration is completed, the counter P1 is incremented by 1 in each mobile terminal master clock cycle, and the master clock cycle is set to T1, then when the value of the counter is P2, the time K2 of the mobile terminal should be:
K2＝K1＋（P2－P1）＊T1。
at present, a counter in a mobile terminal is always absolutely sufficient, and counting from zero can be generally used for hundreds of years; however, due to the characteristics of portability and the like of the mobile terminal, the value of the counter is difficult to be modified due to factors such as static electricity, magnetic field, falling or chip quality problems in the environment in daily use of the mobile terminal; when the value of the counter is modified accidentally, the time of the mobile terminal is incorrect firstly, and then the user can correct the time through a network or manually; however, when the value of the counter is accidentally modified to be close to the overflow value, after a user uses a network or manually for correcting time (which may be as short as one hour, and may be as long as five years), the time is displayed incorrectly for the second time due to the overflow of the counter, which causes trouble to the user and even delays the user.
That is, in the prior art, for example, the value of the counter is accidentally modified to P3 due to static electricity, magnetic field, dropping or chip quality problems in the environment, and P3 is very close to the maximum value P4 of the counter; when the user finds that the time is incorrect, the time is corrected through a network or manually, but after a period of time, the value of the counter reaches the maximum value P4, and then the counter is overflowed and becomes zero; at this time, the value of the counter becomes zero, which causes a time display error, and brings trouble to the user, even delays the user.
Accordingly, the prior art is yet to be improved and developed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a time calibration control method based on a mobile terminal according to a preferred embodiment of the present invention. As shown in fig. 1, the time correction control method based on a mobile terminal according to the embodiment of the present invention includes the following steps:
s100, the mobile terminal starts a timer to detect the value of a counter every other set time, and compares the value of the counter with the set threshold;
specifically, the set threshold is preferably 80% of the maximum value P4 of the counter, for example, the maximum count value P4 of the counter of the mobile terminal is stored in a 16-bit register, and the maximum count value P4 is 16 times of 2 minus 1, and the set threshold is preferably 80% of (16 times of 2 minus 1).
The timer, whose timeout time is the maximum counter value P4 multiplied by the clock frequency multiplied by 10%, for example, the main clock frequency of the mobile terminal is 100000000Hz, the maximum counter value P4 is stored in a 16-bit register, the maximum counter value P4 is the 16 th power of 2 minus 1, and the timeout time of the timer is set to 10% of the product of (the 16 th power of 2 minus 1) and 100000000;
further, step S100 includes the steps of:
starting a timer;
detecting a value of the counter when the timer times out;
the value of the counter is compared with the set threshold.
S200, when the value of the counter is larger than a set threshold, acquiring that the current time is K;
that is, in the present invention, when the value of the counter is greater than the set threshold (for example, the set threshold is preferably (the power 16 of 2 minus 1) 80%), the current time is K, for example, 11.00 whole.
When the value of the counter is accidentally modified (for example, greater than a set threshold) due to factors such as static electricity, magnetic field, falling or chip quality problems in the environment, secondary time display errors caused by overflow of the counter can be effectively avoided, the accuracy of time display is improved, and therefore the use of a user is facilitated.
In the implementation of the present invention, for example, the count value of the mobile terminal is stored in a 16-bit register, and the current value of the 16-bit register is 0000000000000011 (binary representation); the value of the 16-bit register is then modified to 0100000000000011 (binary representation) by accidental modification due to static electricity, magnetic fields, dropouts, or chip quality issues in the environment.
Note: 0000000000000011 (binary representation) is decimal 3 and 0100000000000011 (binary representation) is decimal 16387
Clearly 3 is very different from 16387; 16387 if the threshold is 16000, the threshold is exceeded.
In the invention, when the value of the counter is greater than the set threshold, the current time is acquired to be K.
And S300, resetting the value of the counter and corresponding to the current time K.
Specifically, by resetting the counter even if the value of the counter is zero, the value of the counter is then corresponded to the current time K acquired in step S200 as a new correction time; in this case, when the value of the counter is P2, the time K2 of the mobile terminal should be K2 ═ K1 + (P2-P1) _ T1; where T1 is the master clock cycle, P1 is the count value (i.e., zero) corresponding to time K after the reset in step S3, and K1 is K.
For example: assuming that the master clock cycle T1 is 0.001 second, the current time K obtained in step S200 is 199.99 seconds, and the value P1 of the counter is 0 (P1 is the count value corresponding to the time K after being reset in step S3, that is, zero); the current time K is mapped as a new correction time, i.e. K1= K =199.99 seconds;
when the time is over, the value P2 of the counter is 1000, and the time K2 of the mobile terminal is K2 ═ K1 + (P2-P1) _ T1=199.99 seconds + (1000-0) × 0.001 seconds = 200.99 seconds.
In view of the above, the present invention provides a time correction control method based on a mobile terminal, which detects the value of a counter every set time by starting a timer, and compares the value of the counter with the set threshold; when the value of the counter is larger than a set threshold, acquiring that the current time is K; the value of the counter is reset and corresponds to the current time K. When the value of the counter is accidentally modified due to factors such as static electricity, a magnetic field, falling or chip quality problems in the environment, secondary time display errors caused by overflow of the counter can be effectively avoided, the accuracy of time display is improved, and therefore the counter is convenient for users to use.
