All kinds of social activities are carried out along with time, and the clock is one of the main reliance on knowing the current time point. For a specific time to carry out a specific activity, how to make the activities in different places on time is crucial The clock is a test. That is, how to make the time points of the clocks scattered everywhere consistent. Some countries provide a plan to transmit standard time point information through a wireless transmitting station, so that the clocks scattered everywhere can be synchronized with it at any time. The clocks scattered everywhere can be synchronized with the standard time, so that the clocks scattered everywhere can have a consistent timetable. A clock capable of wireless time synchronization must have some functional circuits, as shown in FIG. 1 , the wireless clock includes an antenna 11 , a receiving circuit 12 and a processor 13 . The receiving circuit 12 receives the standard time information transmitted by the transmitting station through the antenna 11 and sends it to the processor 13 . Processor 13 control includes the processing of time-setting work, and the time-setting work must have a positioning mechanism to be successfully completed, that is, a positioning mechanism for initializing it at the hour, minute, and second must be provided. The current implementation is mainly to initialize the hour, minute, and second as zero hours, minutes, and seconds. When the time synchronization function is activated for the clock, the clock first resets the hours, minutes, and seconds to zero, and then the processor controls the hours, minutes, and seconds to the position of the standard time with the help of the standard time information. , and complete the timing work. Under the high development of science and technology, the current clocks have automatic time synchronization function, that is, the clock can automatically start the time synchronization function at a specific time point. Usually, the time point is set in the early morning when the degree of radio wave interference is small, and the automatic time synchronization function Functionality depends on processor choice.

Now consider a watch company, which is full of various clocks and watches. The timing work of hundreds or thousands of clocks is a great challenge to the staff of the watch company. More attention will be paid to the correct time point. In view of this, the author has developed a counter clock.

Now in conjunction with accompanying drawing, the utility model is further described:

For the rotation of the hour, minute and banknote hands of a mechanical clock, a rotor is generally used to drive the second hand gear, the second hand gear drives the minute hand gear through the reduction gear, and the minute hand gear drives the hour hand gear through the reduction gear, so that the second hand makes a circle and the minute hand travels 60 One-tenth of a circle, when the minute hand circles one week, the hour hand walks one-twelfth of a circle. The utility model is based on this mechanical clock, and adds an automatic time-setting function to become a wireless clock. Please refer to shown in Fig. 2, the wireless clock 2 of the utility model utilizes gear module transmission to realize the hours, minutes, banknote needles as general mechanical clocks. The wireless pair clock 2 includes an antenna 21, a receiving circuit 22 and a processor 23. The receiving circuit 22 receives the time synchronization time information transmitted by the transmitter through the antenna 21 and sends it to the processor 23. Processing of work. Considering the positioning mechanism now, when the wireless clock 2 of the utility model starts the time synchronization function, the hour, minute and second hands are also initialized and returned to zero. When zero point (12), its corresponding gear 32 just circles a circle, and the utility model promptly utilizes this phenomenon, and the photoelectric element 33 of a kind of reflective photoelectric switch is fixed outside this gear 32 near circumference (please cooperate as shown in Fig. 3B), A positioning identification point 34 is set near the circumference of the gear 32 corresponding to the photoelectric element 33, wherein the photoelectric element 33 emits light in the near circumference of the gear 32, so that the positioning identification point 34 can be used as a reference point, as the utility model The radio judges the zero point initialization of the clock 2. Because the photoelectric element 33 is a kind of reflective photoelectric switch, the positioning identification point 34 is formed as an object with better reflection coefficient, and the gear 32 carried is an object with poor reflection coefficient. Using the photoelectric element 33 and the positioning identification point 34 When relative, different reflection changes are produced to determine the cycle period of the gear 32. As shown in Figure 4A, when the photoelectric element 33 is relative to the gear 32 body, its output is a low-state potential. Its output then changes to high-state potential, and then processor 23 can grab this signal that turns to high-energy by low-state as judging the cycle cycle of the gear, thereby realizing that the hour, minute and second hands of the wireless clock of the utility model are initialized and returned. mechanism for the zero point.

Illustrate the means of the positioning mechanism of the present invention with an example, and consider the time spent on positioning. If the second hand gear of the present invention drives the minute hand gear through the reduction gear, and the minute hand gear drives the hour hand gear through the reduction gear, then the positioning time under this structure It will be time-consuming and inefficient. When the positioning identification point 34 is opposite to the photoelectric element 33, the hour, minute, and second hands all point to 12 o'clock (zero point). If the time synchronization function is activated at one o'clock, the second hand needs to circle 660 Zhou Fang can return the hour, minute and second hands to zero, that is, the second hand needs to circle 660 weeks to make the positioning identification point 34 and the photoelectric element 33 face each other again. It is conceivable that it takes a lot of time and money. Quite inefficient way, the utility model utilizes two sets of motors 24, 25 (please cooperate as shown in Fig. 2 ) based on this, one motor 24 is to drive the second hand gear, and the other motor 25 is then to drive the minute hand gear. Please refer to Fig. 3B again, the minute gear 35 drives the hour gear 32 via a reduction gear (not shown), the obvious second gear is independent of the minute and hour gears and has no interlocking relationship, and the motors 24 and 25 are controlled by the processor 23 control, instant, minute, needle hour can be controlled by processor 23. Since the second hand gear is an independent body, the technical means disclosed in Figure 3 must be applied to the second hand gear to obtain the judgment of the second hand's circular cycle. Now consider that the infinite pair of clocks 2 starts the time synchronization function, assuming that the second hand of the infinite pair of clocks 2 and When the time point of the hour and minute hand positioning is relative to the photoelectric element, the hour, minute, and second hands all point to 12 o'clock (zero point), and the time synchronization function is started at one o'clock. At this time, the processor 23 detects the second hand and the hour and minute hand positioning. Whether the time point is opposite to the photoelectric element, and the second hand at this time is starting from the zero point (12), and the positioning of the second hand determines that the time point is opposite to the photoelectric element when the second hand circles around. At this time, the processor 23 terminates the action of the motor 24. And make the second hand stop at zero (12), as for the positioning of the hour and minute hands, when the time point is relative to the photoelectric element, when the minute hand circles 11 times, the processor 23 terminates the motor 25 action, and the hour and minute hands stop at Zero (12), after the hour, minute, and second hands all return to zero, the processor 23 waits for the number of seconds of the received time point message to be zero, and immediately starts the motor 24 so that the second hand is synchronized with the transmitter of the time message. Seconds, during which the processor 23 controls the motor 25 to point the hour and minute hands to the hour and minute points of the time point information received by the processor 23 to complete the time synchronization work, and then the hour, minute and second hands operate normally like ordinary clocks and watches . In the same way, the utility model can also utilize three sets of motors to control the gears of the hour, minute, and second hands respectively. The hour, minute, and second hand gears are all equipped with positioning identification points and corresponding photoelectric elements, and the work of time synchronization can also be completed.

Now consider the accuracy of positioning the hour and minute hands at the zero point (12) in Figure 2. When the minute hand gear makes a circle, the hour hand gear makes a circle for 1/12th of a circle, corresponding to the pointer. Although it is not easy to be detected by the naked eye, there is a 12-fold deviation for the minute hand. Please refer to FIG. When the element 33 is positioned relative to the identification point 34, the output signal of the photoelectric element 33 changes from a low state to a high state. Once the processor 23 learns that the output signal of the photoelectric element 33 turns into a high state, it judges that the hour hand and the minute hand have reached the high state. Returning to zero and terminating the operation of the motor, it is not known that the positioning of the time point 34 and the surface of the photoelectric element 33 have their range of induction, which may cause a slight deviation in the hour hand pointing to the zero point (12), and the minute hand may be easy to observe. deviation, the utility model sets a positioning rod 37 on the minute hand gear shaft 36 at this time (please cooperate with Fig. 4B, shown in Fig. 5), this positioning rod 37 is parallel to the minute hand 38, assuming that the photoelectric element 33 and the hour hand gear 32 When the positioning identification point 34 on the top is opposite, when the instant hand 31 points to the zero point (12), the minute hand 38 has not yet accurately pointed to the zero point (12). The motor still continues to move until the minute hand 38 points to the zero point (12), and the motor stops. This is because when the minute hand 38 points to the zero point (12), the corresponding positioning rod 37 is between the photoelectric element 33 and the positioning time point. 34, that is, the photoelectric element 33 emits light to the positioning rod 37, and the positioning rod 37 has an object with a poor reflection coefficient like the gear body, so the output signal of the photoelectric element 33 changes from a high state to a low state. The time when the high state is turned into a low state can be used as a judgment to judge that the hour hand 31 and the minute hand 38 point to the zero point (12), thereby accurately ensuring that the hour hand and the minute hand are positioned to point to the zero point (12), and avoiding the hour hand from being slightly difficult to detect The deviation of the minute hand affects the easily detectable deviation of the minute hand.

Wireless clocking has been implemented in Europe and the United States. For the main receiving circuit and the functional circuit of the processor, there are corresponding ICs available for reference. Therefore, the utility model is not described, and the utility model is characterized in that it includes How to have the automatic time function of the mechanical clock with hands, minutes, and seconds hands? In addition to the functional circuit of the receiving circuit and the processor, the utility model must consider the positioning mechanism as a judgment for the reset initialization. The utility model uses photoelectric elements to detect The gear rotation cycle is used to realize the positioning mechanism, but if the traditional gear structure is used, that is, a rotor is used to drive the second hand gear, the second hand gear drives the minute hand gear through the reduction gear, and the minute hand gear drives the hour hand gear through the reduction gear. There will be concerns about inefficiency in the zero reset action. The utility model separates the second hand gear from the hour and minute hand gears independently, and uses two sets of motors. One motor controls the second hand gear, and the other motor controls the minute hand gear, and the minute hand gear passes through The reduction gear drives the hour hand gear to form a second hand positioning gear and an hour and minute hand positioning structure, which overcomes the time-consuming shortcoming of positioning and returning to zero, and makes the automatic clock alignment of the present utility model more commercially valuable.

The above is a detailed description of the present utility model, but the above narration is only a preferred embodiment of the present utility model, and the scope of the utility model can not be limited, that is, everything made according to the scope of the utility model patent application The equal changes and modifications all still belong to the scope covered by the patent of the present utility model.
