Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail:
A kind of system that realizes alarm clock function of the present invention as shown in Figure 2, this system comprises a power supply 21, storer 22, clock oscillator 23, a control module 24 and an alerting signal generating device 25.Wherein, described control module 24 can be general CPU, and software program for execution is finished software function.This control module 24 further comprises one or more timing interrupters 26, regularly interrupter 26 is a kind of hardware circuits, control module 24 is set to regularly interrupter 26 with timing, regularly interrupter 26 picks up counting then, after arriving the timing of setting, regularly interrupter 26 initiates to interrupt to control module 24, and control module 24 is handled this interruption.But the maximum timing of the timing interrupter of general general CPU is less, usually in 1 hour.Power supply 21 connected storages 22, clock oscillator 23 and the control module 24 of this system are given this storer 22, clock oscillator 23 and control module 24 power supplies; Storer 22 connects control module 24, desired data during storage control unit 24 operations; Clock oscillator 23 connects control module 24, clock signal is provided for control module 24; Control module 24 connects alerting signal generating device 25, controls and drives this alerting signal generating device 25 and produce alerting signal; And this alerting signal generating device 25 is hummer or loudspeaker or luminescent device or Vib., after the trigger pip that receives control module 24, can produce sound or alerting signals such as light or vibration respectively.
When adopting the system of realization alarm clock function shown in Figure 2, a kind of flow process that realizes alarm clock function of the present invention as shown in Figure 3.At first the user is provided with alarm time, and control module is provided with the regularly timing of interrupter according to alarm time again, and regularly interrupter picks up counting then; When alarm time was scheduled in system time arrival, control module sent trigger pip to the alerting signal generating device, triggers out the alerting signal of alerting signal generating device, notifies user's alarm time then.
With reference to Fig. 3, the present invention specifically may further comprise the steps:
Step s101 is provided with alarm time T1 and obtains current system time T0.This alarm time comprises year, month, day, hour, min, second, is expressed as Y1/M1/D1/H1/M1/S1; System time comprises year, month, day, hour, min, second, is expressed as Y0/M0/D0/H0/M0/S0.
Step s102 judges whether electronic product shuts down.Judge promptly whether this electronic product is in the state that demonstration was closed, do not had to major function.If then change step s103, otherwise change step s104.
Step s103, retentive control unit, regularly interrupter, storer and clock oscillator work.
Step s104 judges whether T1 is less than or equal to T0.If then change step s111, otherwise change step s105.
Step s105 judges that T1-T0 is whether greater than the maximum timing N of timing interrupter.If then change step s106, otherwise change step s107.
Step s106 is provided with t=N.
Step s107 is provided with t=T1-T0.
Step s108, the timing that the timing interrupter of control module is set is t.
Step s109 is provided with the sleep pattern that control module and storer are low-power consumption.
Step s110, when the timing of the timing interrupter of control module then after, the update system time.Be about to T0 and be updated to former T0 and t sum, change step s104 then.
Step s111 triggers alarm clock.Control module sends trigger pip to the alerting signal generating device, triggers out the alerting signal of alerting signal generating device, notifies user's alarm time then.
Suppose that regularly the maximum timing N of interrupter is 3600 seconds; It is 2000/01/01/07/50/30 that the user is provided with alarm time T1, promptly 2000 on January 1,7: 50: 30; Getting access to system time T0 is 2000/01/01/06/30/30, promptly 2000 on January 1,6: 30: 30.If the user presses closing key or use instruction to make the electronic product shutdown, even electronic product is in the state that demonstration was closed, do not had to major function, then retentive control unit, regularly interrupter, storer and clock oscillator work, and judge whether T1 is less than or equal to T0; Otherwise judge directly whether T1 is less than or equal to T0.Because T1 is greater than T0, and T1-T0 is 4800 seconds, greater than N, so t=N is set, promptly is set t=3600 second, and be provided with control module regularly the timing of interrupter be t, this timing interrupter picks up counting, control module and storer are the sleep pattern of low-power consumption.
T is after second for process, regularly interrupter initiates to interrupt to control module, the control module update system time, T0 is updated to former T0 and t sum, be about to 2000/01/01/06/30/30 and be updated to 2000/01/01/07/30/30, and then judge whether T1 is less than or equal to T0.Because T1 is greater than T0, and T1-T0 is 1200 seconds, less than N, so t=T1-T0 is set, promptly be set t=1200 second, and be provided with control module regularly the timing of interrupter be t, this timing interrupter picks up counting, and control module and storer are the sleep pattern of low-power consumption.
T is after second for process, regularly interrupter initiates to interrupt to control module, the control module update system time, T0 is updated to former T0 and t sum, be about to 2000/01/01/07/30/30 and be updated to 2000/01/01/07/50/30, and then judge whether T1 is less than or equal to T0.Because T1 equals T0, so control module sends trigger pip to the alerting signal generating device, trigger out the alerting signal of alerting signal generating device, notify user's alarm time then.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
