Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
The term used in the disclosure is only for the object describing specific embodiment, and the not intended to be limiting disclosure." one ", " described " and " being somebody's turn to do " of the singulative used in disclosure and the accompanying claims book is also intended to comprise most form, unless context clearly represents other implications.It is also understood that term "and/or" used herein refer to and comprise one or more project of listing be associated any or all may combine.
Term first, second, third, etc. may be adopted although should be appreciated that to describe various information in the disclosure, these information should not be limited to these terms.These terms are only used for the information of same type to be distinguished from each other out.Such as, when not departing from disclosure scope, the first information also can be called as the second information, and similarly, the second information also can be called as the first information.Depend on linguistic context, word as used in this " if " can be construed as into " ... time " or " when ... time " 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, and the method may be used for also may be used in router in terminal, comprises the following steps:
Step 101, when waking up from resting state, obtain current time information by the mode beyond the reading system time.
Router in the disclosure is as a kind of smart routing devices, and it not only has traditional routing function, can further include SOS and disk, and the storage size of this disk can be arranged as required flexibly, such as, is set to 1T; Terminal in the disclosure can be any intelligent terminal with function of surfing the Net, such as, can be specially mobile phone, panel computer, PDA (Personal Digital Assistant, personal digital assistant) etc.Wherein, terminal can pass through WLAN (wireless local area network) couple in router, and by the server on router access public network.
In the disclosure, terminal or router, in order to reduce power consumption, when not having service needed process, based on setting, can enter resting state.But due to its be in resting state time, the clock of CPU can stop, and that is heartbeat timer can quit work, when thus waking up from resting state, system time is probably inaccurate, and thus terminal or router need again to obtain current time information accurately.
In disclosure step, the accuracy of system clock can be ensured by real-time clock.
Wherein, RTC (Real-Time Clock, real-time clock) relies on the recurrent pulses of external crystal-controlled oscillation generation to carry out the clock of timing, and real-time clock only needs extremely low amount of power supply just can keep running, power consumption is extremely low, can provide reliable timing time for system.Real-time clock can be the built-in clock of the MCU of terminal or router, also can be the real time clock circuit external with the pin of MCU.
In this fashion, before the MCU of terminal or router enters resting state, first can obtain current time information, namely will enter the temporal information of resting state.
In the disclosure, obtaining the temporal information that will enter resting state has various ways, and such as, when will enter resting state, system time is 12 points, then the temporal information that will enter resting state is just 12 points.Before terminal or router enter dormancy, be in normal operating conditions, system heart-throb timer is normal work, and present system time at this time can think correct time.
When terminal or router can be networked, can also obtain from other equipment the temporal information that this will enter resting state.Such as, request can be obtained to other equipment transmitting times such as server or the other-ends connected by network, then receive the temporal information that other equipment return, then enter dormancy, the temporal information that these other equipment return is exactly the temporal information that will enter resting state.
In addition, terminal and router can also to satellite transmitting time solicited messages, comprise GPS (GlobalPositioning System, global positioning system) satellite or big-dipper satellite, then according to the time service information determination temporal information that the satellite received is replied, and entering resting state, this is exactly the temporal information that will enter resting state according to the temporal information that time service information is determined.
Then, this to can be entered the starting counter value of temporal information as real-time clock of resting state, make real-time clock start counting.That is, this to be able to be entered in the register of temporal information write real-time clock of resting state.
When terminal or router are waken up from resting state, read the current count value that real-time clock starts with starting counter value to count to get, and obtain current time information according to current count value.Thereby, it is possible to ensure that terminal or router are after entering resting state, still can obtain precise time.
In the disclosure, computing system current time information accurately can also be carried out by dormancy time length.
Before dormancy, the temporal information that will enter resting state got and carrying out corresponding to dormancy time length can store by terminal or router, thus when terminal or router are waken up from resting state, based on temporal information and the dormancy time length that will enter resting state, current time information can be calculated.
In the disclosure, current time information accurately can also be obtained from other equipment.
That is, after hibernate, can obtain request to other equipment transmitting times such as server or the other-ends connected by network, then receive the temporal information that other equipment return, the temporal information that these other equipment return is exactly current time information.
In the disclosure, terminal and router can also after waking up from resting state, to satellite transmitting time solicited message, then according to the time service information determination current time information that the satellite received is replied.
In the disclosure, the current time information that terminal or router obtain also can be the UTC time.Thus realize the accurate coordination of UTC time.
Step 102, based on obtain current time information present system time is corrected.
Terminal or router are calibrated present system time based on the current time information obtained, such as, present system time is revised as obtained current time information.
