Embodiment
During the utility model work, at first load onto battery, circuit is started working, and microprocessor MCU sends instruction, and second step motor 18 drives second hand wheel group 19; Simultaneously, second optocoupler assembly 14 work: power valve sends an infrared signal, and receiving tube receives this infrared signal and feeds back to MCU.When the some anti-dazzling screens in the second wheel 5 cut off tube-launched infrared signal by optocoupler, receiving tube does not receive this infrared signal, will produce a potential change signal and give MCU, MCU differentiates the position of second wheel 5 according to the length that whether receives potential change signal and signal: when the narrow anti-dazzling screen of second wheel 5 during by the optocoupler assembly, the potential change signal time that produces owing to its partition infrared signal does not reach a certain numerical value, and MCU does not send alteration command; When the wide anti-dazzling screen of second wheel 5 passes through the optocoupler assembly, it cuts off infrared signal and the potential change signal time that produces reaches a certain numerical value, MCU sends instruction, second, step motor 18 rotating speeds were slack-off, second wheel 5 becomes slow running by fast turn-around, 4 steps of being careful again stop, the position of second wheel 5 this moment just just at 00:00, a second optocoupler assembly quits work.MCU sends instruction simultaneously, time-division optocoupler assembly 15 is started working, divide the stepping motor 17 fast turn-arounds, driving minute wheel 10 by reduction gearing rotates with hour wheel 11: divided at that time optocoupler assembly 15 detect one have 144 branch motor step number times when light signal, MCU is that this anti-dazzling screen of decidable is the narrow anti-dazzling screen C on the hour wheel, divide stepping motor 17 to transfer microrunning to, again through 36 steps detect again one 24 branch motor step number times when the light signal, MCU is that this anti-dazzling screen of decidable is the wide anti-dazzling screen E on the minute wheel, MCU promptly sends instruction, divide stepping motor 17 to shut down, minute hand is parked in the 00:00 position, hour hands are parked in the 4:00 position, and the MCU internal time is AM4:00, and MCU sends instruction and begins to receive electric wave signal; Divided at that time optocoupler assembly 15 detect one have 264 branch motor step number times when light signal, MCU is that this anti-dazzling screen of decidable is the anti-dazzling screen B on the hour wheel, divide stepping motor 17 to transfer microrunning to, again through 36 steps detect again one 24 branch motor step number times when the light signal, MCU is that this anti-dazzling screen of decidable is the wide anti-dazzling screen E on the minute wheel, MCU promptly sends instruction, divide stepping motor 17 to shut down, minute hand is parked in the 00:00 position, hour hands are parked in the 8:00 position, the MCU internal time is AM8:00, and MCU sends instruction and begins to receive electric wave signal; Divided at that time optocoupler assembly 15 detect one have 384 branch motor step number times when light signal, MCU is that this anti-dazzling screen of decidable is the wide anti-dazzling screen A on the hour wheel, divide stepping motor 17 to transfer microrunning to, again through 36 steps detect again one 24 branch motor step number times when the light signal, MCU is that this anti-dazzling screen of decidable is the wide anti-dazzling screen E on the minute wheel, MCU promptly sends instruction, divide stepping motor 17 to shut down, minute hand is parked in the 00:00 position, and hour hands are parked in the 00:00 position, and the MCU internal time is AM00:00, MCU sends instruction and begins to receive electric wave signal, at this moment, the time, divide, second hand is all in the 00:00 position, realizes the three pins location of making zero.
Three anti-dazzling screen width on the second wheel are different, and when detecting wide anti-dazzling screen, a second step motor 18 transfers slow running to, reduced gear operation inertia, and second wheel is accurately stopped operating at anchor point.Same reason, three anti-dazzling screen width on the minute wheel are also different, and MCU detects hour wheel anti-dazzling screen time-division step motor and also transfers slow running to, has reduced gear operation inertia, and minute wheel is accurately stopped operating at anchor point.
Electric wave optical alignment control system of the present utility model is the novel indicator type electric wave clock movement cranking wheel control system of a cover, the second wheel gear set and the time center arbor group by separately independently step motor drive simultaneously; Since second wheel with the time, minute wheel is by the independently photoelectrical coupler detection position and the positioning control of making zero separately, have the location and wait advantage accurately and fast.
