During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
It is only merely for the purpose of description specific embodiment in the term that the disclosure uses, and is not intended to be limiting the disclosure.
" one kind " of singulative used in disclosure and the accompanying claims book, " described " and "the" are also intended to including majority
Form, unless context clearly shows that other implications.It is also understood that term "and/or" used herein refers to and wrapped
Containing the associated list items purpose of one or more, any or all may be combined.
It will be appreciated that though various information, but this may be described using term first, second, third, etc. in the disclosure
A little information should not necessarily be limited by these terms.These terms are only used for same type of information being distinguished from each other out.For example, do not departing from
In the case of disclosure scope, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as
One information.Depending on linguistic context, word as used in this " if " can be construed to " ... when " or " when ...
When " or " in response to determining ".
As shown in figure 1, Fig. 1 is a kind of time-correcting method flow chart according to an exemplary embodiment, this method
It can be used in terminal can be used in router, comprise the following steps：
Step 101, from resting state wake up when, obtain current time information by way of reading beyond system time.
As a kind of smart routing devices, it not only has traditional routing function for router in the disclosure, can be with
Further comprise SOS and disk, the storage size of the disk can flexibly be set as needed, for example, setting
It is set to 1T；Terminal in the disclosure can be any intelligent terminal with function of surfing the Net, for example, can be specially mobile phone, flat
Plate computer, PDA (Personal Digital Assistant, personal digital assistant) etc..Wherein, terminal can pass through wireless office
Domain net couple in router, and pass through the server on router access public network.
In the disclosure, terminal or router are in order to reduce power consumption,, can be with based on setting when no business needs processing
Into resting state.But due to its in a dormant state when, CPU clock can stop, that is to say, that heartbeat timer can stop
Only work, thus from resting state wake up when, system time is likely to be inaccurate, thus terminal or router need weight
Newly obtain accurate current time information.
In disclosure step, the accuracy of system clock can be ensured by real-time clock.
Wherein, RTC (Real-Time Clock, real-time clock) is entered by recurrent pulses caused by external crystal-controlled oscillation
The clock of row timing, real-time clock only need extremely low delivery just to remain on, and power consumption is extremely low, and can be provided for system can
The timing time leaned on.Real-time clock can be the clock built in the MCU of terminal or router, or with outside MCU pin
The real time clock circuit connect.
In this fashion, before the MCU of terminal or router enters resting state, current time letter can first be obtained
Breath, that is, to enter the temporal information of resting state.
In the disclosure, the temporal information that resting state will be entered by obtaining have various ways, such as when entering resting state,
System time is 12 points, then the temporal information that enter resting state is just 12 points.Before terminal or router enter dormancy,
In normal operating conditions, system heart-throb timer is normal work, and present system time at this time may be considered standard
The true time.
When terminal or router can network, this can also be obtained at other equipment will enter the time of resting state
Information.For example, can be to server or the other equipment such as the other-end that passes through network connection sends the time and obtains request, then
The temporal information that other equipment returns is received, subsequently into dormancy, the temporal information that the other equipment returns seeks to enter not
The temporal information of dormancy state.
In addition, terminal and router can also send time request information, including GPS (Global to satellite
Positioning System, global positioning system) satellite or big-dipper satellite, the time service then replied according to the satellite received
Information determines temporal information, and enters resting state, and the temporal information determined according to time service information seeks to enter dormancy shape
The temporal information of state.
It is then possible to which this will be entered to starting counter value of the temporal information as real-time clock of resting state, order is real-time
Clock starts counting up.That is, the temporal information that this will can be entered to resting state is write in the register of real-time clock.
When terminal or router are waken up from resting state, read real-time clock and start counting up to obtain with starting counter value
Current count value, and current time information is worth to according to current count.Thereby, it is possible to ensure that terminal or router are entering
After resting state, it still is able to obtain the accurate time.
, can also be by dormancy time length come the accurate current time information of computing system in the disclosure.
Before dormancy, when temporal information and the dormancy that to enter resting state that terminal or router will can be got
Between stored corresponding to length, so as to when terminal or router are waken up from resting state, be based on entering dormancy
The temporal information and dormancy time length of state, calculate current time information.
In the disclosure, accurate current time information can also be obtained at other equipment.
, can be to server or the other equipment hair such as the other-end that passes through network connection that is, after hibernate
Send the time obtain request, then receive other equipment return temporal information, the other equipment return temporal information be exactly when
Preceding temporal information.
In the disclosure, terminal and router can also send time request letter after being waken up from resting state to satellite
Breath, the time service information then replied according to the satellite received determine current time information.
In the disclosure, the current time information of terminal or router acquisition can also be UTC time.During so as to realize UTC
Between accurate coordination.
Step 102, the current time information based on acquisition are corrected to present system time.
The current time information of terminal or router based on acquisition is calibrated to present system time, such as will be currently
System time modification is acquired current time information.
As shown in Fig. 2 Fig. 2 is a kind of correct application field of system time of the disclosure according to an exemplary embodiment
Scape schematic diagram.In the scene shown in Fig. 2, including：As the millet router of router, and as with the millet router
The terminal millet smart mobile phone of networking.Real-time clock is built-in with the millet router.
Millet router sends time acquisition request, millet intelligence before resting state is entered, to millet smart mobile phone
Mobile phone sends temporal information this moment to millet router, and millet router is real-time as built in using the temporal information received
The starting counter value of clock, subsequently into resting state.Millet router from resting state wake up when, obtain real-time clock work as
The preceding time, and with the current time modification present system time, so as to realize the accurate calibration to system time.
