Radio time-setting clock (Radio Clock, but R/C) standard time that the time of reception cell site launched and row to the time work, this Radio time-setting clock have into electricity to the time (Power-on), force to the time and regularly to the time function.Go into electricity to time system utilize start when settling power supply to the time function; Force to time system via the user start to the time function; Regularly to the time lie in that a specific time point starts voluntarily to the time function.Shown in Figure 1 is existing Radio time-setting clock principle of work, receiving circuit 12 receives the time message of cell site's emission by antenna 11 and processor 13 is delivered in it decoding handled, processor 13 be responsible for control whole to the time functional operation, Radio time-setting clock start to the time during function, zero second anchor point of zero when these processor 13 control motors make, when the minute, second pin is returned to zero (12).And the time, whether the minute, second pin return to anchor point, general system utilizes photovalve 16 as judgment mechanism, photovalve 16 judgment mechanisms systems by the time (minute, second) pin gear positioning identification point 17 of being provided with, whether (minute, second) pin gear 18 to anchor point when judging.When the positioning identification of (minute, second) pin gear 18 puts 17 when photovalve 16 recognizes, i.e. expression corresponding the time (minute, second) returned anchor point (seeing also shown in Figure 2) to zero point.For mechanical wireless to clock the time, the minute, second pin rotates, utilize a rotor to drive second hand wheel if be, second hand wheel drives minute gear via reduction gearing, minute gear drives hour hand gear via reduction gearing again, so, if start to the time function and should the time, the minute, second pin returns to anchor point, will spend the tediously long time.For example, suppose in the one o'clock start to the time function, when photovalve recognized the positioning identification point of hour hand gear, corresponding second hand must belt can sense the positioning identification point of hour hands 660 weeks.Return to the time-consuming problem of anchor point for solving second hand, mechanical wireless often utilizes two groups of motors to drive second, minute gear (please cooperating shown in Figure 1 again) respectively to clock, motor 14 is to drive second hand wheel, minute gear when 15 in another motor drives, making second hand wheel be independent of branch, hour hand gear does not have continuous action relation outward.Please cooperate shown in Figure 2 again, minute gear 19 drives hour hand gear 18 via reduction gearing (figure does not show), hour hand gear is provided with positioning identification point 17, when photovalve 16 senses this positioning identification point 17, this moment corresponding the time, minute hand returns to anchor point (12 positions), in like manner also be provided with the positioning identification point, to allow corresponding another photovalve that is provided with that it is judged whether to return to anchor point at second hand wheel.In such event, suppose in some zeros zero second whole start to the time function, second hand wheel goes in ring and can allow its positioning identification point of photovalve sensing a week, and makes second hand stop at (12) position at zero point.But, when the positioning identification point 17 of hour hands allows photovalve 16 sense, its minute gear 19 still must go in ring and can sense in 11 weeks, and when making, minute hand stops at zero point (12), though compare aforesaid go into electricity to the time (Power-on), force setting means, though when saving greatly, the location time-histories of minute, second pin, but must cost the reasonable time.
The object of the invention ties up to when a kind of can finishing fast is provided, the setting means of the Radio time-setting clock of the location action of minute, second pin.
The technical scheme that solves the object of the invention is such: Radio time-setting clock setting means regularly, it is characterized in that it is when utilizing a photovalve with sensing, the positioning identification point of minute, second pin gear, as this clock start to the time during function, when judging, whether the minute, second pin return to the location, be used in hour hand gear simultaneously the positioning identification points of organizing different in width are set more, to allow photovalve when the positioning identification point of these different in width of sensing, learn why person's time point of time corresponding, thus when being finished fast, the location of minute, second pin to the time method.
Compared with prior art, the present invention has when finishing fast, the location of minute, second pin to the time function, can save greatly to the time time.
Specifically describe the present invention below by drawings and Examples.
Consult shown in Fig. 3 A is the physical construction synoptic diagram of Radio time-setting clock of the present invention.When including, minute, second pin gear 31,32,33, it utilize two groups of motors 34,35 with drive respectively second, minute gear.Wherein motor 34 is to drive second hand wheel, and 35 in motor drives minute gear, and this minute gear drives hour hand gear 31 via reduction gearing 37.
Can know from Fig. 3 B synoptic diagram and to find out, when Radio time-setting clock of the present invention utilizes a photovalve 38 sensings, the positioning identification point 311,321,331 of minute, second pin gear, as start to the time when judging during function, whether the minute, second pin gear return to anchor point.When shortening this, divide, second hand is returned the time-histories to anchor point, the present invention utilizes hour hand gear 31 that the positioning identification point 311 of many group branches such as (are example with 3 groups) is set, 312,313 (seeing also shown in Figure 4), when photovalve 38 sense positioning identification when putting 311 its corresponding hour hands be positioned at and point to 12 positions, when photovalve sense positioning identification when putting 312 its corresponding hour hands be positioned at 4 positions, when photovalve sense positioning identification when putting 313 its corresponding hour hands be positioned at 8 positions, utilize this 3 groups of positioning identification points 311,312,313 different width, learn to be what person's time point when allowing photovalve sensing one positioning identification point, now illustrate, suppose that photovalve 38 is to comprise a receiver, utilize photovalve 38 luminous to this receiver, if can keep a current potential (being assumed to be noble potential) when receiver receives the light path of photovalve 38 emission, when devoting receiver as if the light path that covers photovalve 38, photovalve then transition is an electronegative potential, so, can can learn that what person's time point the positioning identification point of existing sensing is by the different sensing time (shading time), Radio time-setting clock of the present invention like this allows minute gear go in ring in the time of can finishing at the most all around, divide, the location of second hand, and shorten the location time-histories greatly.For example, suppose in the one o'clock start to the time function, this photovalve promptly begins start, when processor begins to detect this moment, divide, second, whether the positioning identification point of gear was sensed by photovalve, if not having then, second hand begins to rotate, when the belt circle (supposing that second hand is from 12 positions) of second wheel can be sensed its positioning identification point by photovalve, this moment, processor stopped the motor action, and make second hand stop at (12) position at zero point, as for the time, minute wheel, when belt three circles of minute gear, the positioning identification point 312 of this hour hand gear is promptly sensed by photovalve, its processor promptly stops the motor action, and make minute hand stop at zero point (12), and hour hands stop at 4 positions, thereafter, its processor is waited for when the second number of the time point message that is received is zero, at once starter motor and make the second hand reference synchronization time the second number time, around here processor control motor with the time, the minute hand directional processors receive the time point message the time, the time point that divides, and finish to the time work, in the time of then, divide, second hand just as clock and watch operate normally.By this, Radio time-setting clock of the present invention start to the time during function, at that time, minute hand walk to anchor point allow at the most capable four circles of minute gear get final product (as if be start-up time 12,8 or 4 the time), compare existing Radio time-setting clock, then can save greatly to the time time.
Fig. 4 for Radio time-setting clock of the present invention by a photovalve one by one to the time, the minute, second gear makees the mode synoptic diagram of sensing.Can know from this figure and to find out, the present invention utilize a photovalve to the time, divide, when second hand wheel is done the work of time location, take one by one to the time, the every minute and second gear is done the mode of sensing, that is: allow second gear 33 rotate the sense position (please cooperate picture shown in) of a distance (promptly going further the moving several seconds) earlier to abdicate photovalve 38, the minute hand motor begins to drive minute gear 32 in the time of hereat, during photovalve 38 beginning sensings, divide gear 31,32 positioning identification point, during as for judgement, divide gear when to return to the location, this photovalve can sense the positioning identification point 311 (312/313) of hour hand gear earlier, simultaneously learn why person's time point of time corresponding by the difference of sensing time, then can sense the positioning identification point 321 of minute gear 32 then, when the positioning identification 321 of the intact minute gear 32 of sensing, when promptly finishing, the location of minute gear.
For Radio time-setting clock of the present invention utilize a photovalve when judging, whether the minute, second pin gear to the location, utilize hour hand gear that many group positioning identification points are set simultaneously and finish location work fast having, in start to the time during function, then its to the time program step comprise: A, begin to start photovalve sensing positioning identification point; B, judgement have or not the positioning identification point to be sensed by photovalve; C, if step B sense the positioning identification point, then Hour Minute Second and second hand motor reach and remain in operation; D, when photovalve does not have the sensing positioning identification, minute hand motor running when stopping at once, and the second hand motor remains in operation; E, judge whether photovalve has the positioning identification point identification point that senses second hand wheel; F, if after step e senses the positioning identification of second hand wheel, then the second hand wheel distance of walking is again abdicated the sense position of photovalve and is promptly stopped the second hand motor running, finishes the second hand location hereat; G, finish minute hand motor running when promptly starting when second hand location; H, photovalve begin to judge the positioning identification point of hour hand gear, and distinguish its why positioning identification point of person's time point; I, when the judgement of the positioning identification point of finishing hour hand gear, this photovalve continues to judge and has or not the positioning identification point that senses minute gear; J, sense the positioning identification point of minute gear when photovalve, minute hand motor running when promptly stopping, when finishing hereat, minute hand location, then this Radio time-setting clock is according to the time point message of acquisition, with the time, minute, second pin control is adjusted to the position of this time point message, and continue to do timework.
