The utility model is work like this:

One, the dress electricity when chasing after to the time proofread and correct:

Circuit diagram is seen Fig. 1.

Earlier hour hands 9, minute hand 8, second hand 10 are contained in a certain preposition, it is a certain specific time, 3:00:00 for example, start radio system 2 then, radio standard time long-wave signal amplifies the internal register 4 of demodulation outputting standard timing code to CPU3 through antenna 1 to radio system 2, CPU8 is according to the difference of register 4 with special time, and driving time-division needle drivers 6, second hand driver 7 are hurried up and proofreaied and correct when chasing after.When cell voltage is low, CPU3 detects the drive signal that the low signal of cell voltage is just closed time-division driver 6 and second hand driver 7 by battery voltage detector 12, time that simultaneously will this moment is charged in the storing apparatus 11, for example nonvolatile memory EEPROM etc.When reloading new battery, CPU3 starts radio system 2 earlier, radio signal is through antenna 1, receiving trap 2 to CPU3 internal registers 4, and CPU3 pursues to correct time according to the difference of register 4 and nonvolatile memory 11 by time-division needle drivers 6 and second hand driver 7.If it is very short to change the time of battery, and original radio wave clock will be hurried up earlier when powering up to a certain ad-hoc location, may need long time, also to differentiate pointer position simultaneously by infrared detection system, power consumption is very big, in the time of after receiving radiotick, also will chasing after then, course of work trouble, efficient is low, the time only is mistiming or the replacing battery shared time of predefined special time to orthochronous when chasing after through the setting means that upgrades, do not need infrared detection to judge whether that pointer puts in place yet, this setting means is required when chasing after to the time time short, the power consumptive province, the efficient height.For example certain clock and watch is parked in the 1:10:00 position, and the time behind the replacing battery is 1:20:00, and working method originally may need long time just can make pointer get back to the correct time.And may only need just can make pointer get back to the correct time about 20 seconds now.

Two, the hand-manipulating of needle is proofreaied and correct:

The internal clocking of CPU3 is by quartz oscillator 16 decisions, and establishing quartz oscillator 16 desirable oscillation frequency is 32768Hz.Because be subjected to the influence of quartz oscillator precision and temperature stability, frequency always departs from 32768Hz, thereby influences the precision of the hand-manipulating of needle.By starting at interval radio system 2, and by 5 pairs of CPU internal clockings countings of counter, can make the interval time of regulating the CD-ROM drive motor pulse by the count value of counter 5 hand-manipulating of needle time and standard time synchronous then.For example: 2:00:00 startup in morning standard time every day CPU inside increases 1 counter 5,3:00:00 closes counter 5 to morning standard time, if the CPU machine cycle is 4 times of the clock period, then the count value of counter 5 should be 29491200 when bias free, when the count value of counter 5 greater than 29491200 the time, the expression cpu clock is faster than the standard time, can make the hand-manipulating of needle time consistent with the standard time by increasing the pointer driver drives method of interpulse period.When the count value of counter 5 less than 29491200 the time, the expression cpu clock is slow through the standard time, can make the hand-manipulating of needle time consistent with the standard time by reducing the pointer driver drives method of interpulse period.Perhaps count value was removed unnecessary 29491200 pulse greater than 29491200 o'clock, when count value less than 29491200 the time, increase pulse and make it to satisfy 29491200 method and make the hand-manipulating of needle time consistent with the standard time.

Three, infrared correction hand-manipulating of needle site error:

For further guaranteeing the accuracy of hand-manipulating of needle position, for example mechanical reason causes that time error can proofread and correct by the mode of infrared detection, CPU control.

Radio wave clock movement sectional view is seen Fig. 2, through amplify the time, divide the location photodetector system to see Fig. 3, location photodetector system second through amplifying is seen Fig. 4.

Regularly starting an infrared emission system every day detects hand-manipulating of needle position and proofreaies and correct by CPU3 control time-division needle drivers 6 and second hand driver 7.For example: every day, CPU internal clocking 3:00:00 in morning started infrared emission system 18, infrared light is received by infrared receiving tube 14 by the through hole on the second wheel 20 17 when second hand is error free, represent that its pointer time and CPU internal time are synchronous, to receive the time ratio 3:00:00 of infrared lights leading or when lagging behind, the expression second hand has fast clock or slow clock phenomenon when infrared receiving tube 14.During fast clock, CPU3 can proofread and correct to the waiting mode of second hand driver 7 output pulses by stopping, and when slow clock, can proofread and correct by the mode that second hand driver 7 is hurried up, then, start infrared external reflection system 15, when the row clock is error free, the through hole 18 of 15 infrared lights that send on hour wheel pipe 22, by the receiving tube of 21 reflected backs 15 of the reflective mirror on the cannon pinion 19, similarly, if receive the leading or hysteresis of clock is advanced in the inside of penetrating the time ratio CPU3 of light, minute hand has fast clock or slow clock phenomenon during expression.Can just carry out to the mode of time-division needle drivers 6 output driving pulses by stopping during fast clock; During slow clock, can proofread and correct by the mode that time-division needle drivers 6 is hurried up.

The utility model be by acceptance criteria time radio long-wave signal control the hand-manipulating of needle automatically to the time time set when chasing after, can make radio wave clock or Wave timepiece.Time and infrared emission time all shorten greatly when chasing after during the dress electricity, and is low in energy consumption, easy to operate, improved efficient greatly.
