and judging whether the first audio data is matched with preset standard audio data or not, if so, judging and identifying a calibration point passing through the clock movement, wherein the standard audio data is audio data generated when the first metal guide piece and the second metal guide piece collide and contact with each other.
According to the description, whether the calibration point of the clock movement passes or not is judged through two modes of electric signal identification and audio identification, the electric signal identification is carried out firstly, and the audio identification is carried out only when the electric signal is identified, so that the calibration point passing through the clock movement is identified only when the electric signal identification and the audio identification are met simultaneously, and the accurate identification is realized.

According to the description, when the first audio data is not matched with the preset standard audio data, the first electric signal is deleted, so that interference on the subsequent electric signal collected again is avoided, and the identification precision is ensured.
Further, the method for determining whether the first audio data matches with the preset standard audio data includes:

Referring to fig. 1-4, a first embodiment of the present invention is:
the invention provides a high-precision clock alarm starting point calibration method, which comprises the following steps:
s1, starting a motor, wherein an output shaft of the motor drives a shifting needle rod on the clock movement to rotate along one direction at a first rotating speed for adjustment, and specifically, the position parameter of a transmission gear set in the clock movement is adjusted; the one direction is a clockwise direction.
S2, if the calibration point of the clock movement is identified, recording the position parameter corresponding to the needle shifting rod at the current moment to obtain a first position parameter, controlling the output shaft of the motor to continuously drive the needle shifting rod on the clock movement to rotate along the first direction at the first rotation speed, and simultaneously obtaining a second position parameter corresponding to the needle shifting rod in real time;

Wherein the preset range is 10-30 degrees of clock hand rotation.
And S4, stopping the motor when the calibration point of the clock movement is identified.
The invention adopts two identification modes to identify whether the calibration point passes through the clock movement, the first mode is electric signal identification or audio identification, and the first mode specifically comprises the following steps:
using the electrical signal to identify: judging whether the output end of a signal collector outputs an electric signal or not, wherein the input end of the signal collector is respectively and electrically connected with a first metal guide sheet and a second metal guide sheet which are positioned in a clock movement, and the electric signal is generated by the electric contact of the first metal guide sheet and the second metal guide sheet; if yes, the calibration point passing through the clock movement is judged and identified.
Using audio recognition: acquiring audio data sent by a clock movement in real time to obtain second audio data; and judging whether the second audio data is matched with preset standard audio data or not, if so, judging and identifying a calibration point passing through the clock movement, wherein the standard audio data is audio data generated when the first metal guide piece and the second metal guide piece collide and contact with each other.
It should be noted that the electric signal is one or more of a sine wave, a square wave or a sawtooth wave with a preset period.
The second method is that after the electric signal identification, the audio identification is carried out, whether the calibration point of the clock movement passes through is judged by the two modes of the electric signal identification and the audio identification, and the calibration point of the clock movement is identified only when the calibration point of the clock movement is met; the method specifically comprises the following steps:
if the output end of the signal collector outputs an electric signal, audio data sent by the clock movement is collected to obtain first audio data;
and judging whether the first audio data is matched with preset standard audio data or not, if so, judging and identifying a calibration point passing through the clock movement, wherein the standard audio data is audio data generated when the first metal guide piece and the second metal guide piece collide and contact with each other.
If the output end of the signal collector outputs an electric signal, marking the electric signal as a first electric signal; and if the first audio data are not matched with the preset standard audio data, deleting the first electric signal, and judging whether the output end of the signal collector outputs an electric signal again.
Whether the first audio data are matched with the preset standard audio data or not is determined by calculating the matching degree of the first audio data and the preset standard audio data, and a corresponding matching value is obtained; and if the matching value is higher than a preset threshold value, judging that the first audio data is matched with preset standard audio data. The preset threshold is 90%.
And S3, stopping the motor when the calibration point of the clock movement is identified.
In an embodiment, one frame on the clock dial corresponds to a 30 ° central angle, when a calibration point passing through the clock movement is identified, a position parameter corresponding to the dial rod at the current time is recorded, if the data processing efficiency is high, the position parameter corresponding to the dial rod at the current time is recorded to be equal to the position parameter corresponding to the calibration point, if the data processing efficiency is not high enough, some position parameters are passed, for example, the target setting calibration point is 11, but the position parameter corresponding to the dial rod at the current time is recorded to 11.2, that is, 6 ° is passed, and then the dial rod is rotated at a low speed after being rapidly rotated at 330 ° (the preset range of the first position parameter is 30 °), which is equivalent to that the recorded position is changed by 30 ° forward, and the recorded position is used as a position node for speed change.
And when the hand setting rod is located at a certain position and corresponds to a calibration point of the clock movement, the alarm starting point is calibrated, and the needle mounting operation is started.
The alarm function of the clock movement of the invention means that when the minute hand reaches the preset time period of the setting hand, the buzzer in the movement will sound. If the alarm lever (the shaft lever for adjusting the alarm starting point) is preset at 7: 00, opening the sound stopping rod, and moving the hour hand and the minute hand to 7: the 00 buzzer will sound. The alarm is generally designed to sound once every 12 hours (any time period), each time is 25-45 minutes, and the sound volume is above 50 decibels.
The alarm function comprises two parts of a circuit and a structure, wherein the circuit generally comprises a buzzer, a triode (amplification function) and a COB (only the buzzer and the triode are integrated in an IC).
As shown in fig. 2-4, the structure comprises three parts: (1) the switch part comprises a large conducting sheet 1 and a small conducting sheet 2 (namely the first metal conducting sheet and the second metal conducting sheet). (2) The setting and control part: comprises a setting lever 3, a cam plate 4, a 7# wheel 5 and an 8# wheel 6. (3) Stop, start alarm function part: a sound stopping rod 7. Among them, it should be noted that: the needle-setting rod is not shown in the figures, and is a shaft lever for adjusting the rotation of the minute hand and the hour hand, and the needle-setting rod drives a transmission gear set engaged with the needle-setting rod to rotate when rotating and transmits the rotation to the cam disc 4.
Alarm working principle: when the poking needle rod is rotated after the battery is arranged until the size guide sheet is contacted, the battery, the triode and the buzzer 8 form a loop. The current is amplified and transmitted to the buzzer through the triode to drive the buzzer to sound.
As shown in fig. 3, the alarm time control and setting part: in the time period without alarm, the three-point end of the cam disc 4 is propped against the wheel disc of the 8# wheel 6 so as to be propped up against the cam disc, and the other end (the end without the three-point end) of the cam disc jacks up the large guide vane, so that the large guide vane is separated from the small guide vane, and the alarm stopping effect is achieved. The 8# wheel 6 is designed with three holes corresponding to the three tips of the cam plate 4, which can be sunk into the 8# wheel at an angle. The 8# wheel is arranged on the lower cover and is in friction fit with the lower cover. A certain force is required to rotate. If the matching is too loose, the alarm can be driven by the 7# wheel, and the alarm starting time is influenced. If it is too tight, the hand feeling is not good when adjusting. The torque force specified by the scheme is in the range of 40-80 gf/cm. The cam plate passes through the 7# wheel and is driven to rotate by the 7# wheel. When an angle is reached, three tips of the cam disc can sink into the 8# wheel hole, the cam disc sinks to separate from the large guide vane, the large guide vane rebounds to contact the small guide vane, and the buzzer can sound. The 7# wheel continues to rotate the cam plate slowly. After about 25-45 minutes, the three tips of the cam plate are pushed against the inclined plane of the 8# wheel hole to move up slowly, so that the cam plate rises to push the large guide vane, and the buzzer stops alarming. The setting of the alarm time is completed by directly driving the 8# wheel by the alarm pulling rod.
As shown in figure 4, the alarm stopping and starting function part is provided with a sound stopping rod which is assembled on the upper cover and is directly pushed and controlled by manpower, so that the alarm stopping or starting function is achieved. When the ringing stopping rod is pushed inwards, the inclined surface on the ringing stopping rod can hook the large guide vane, so that the large guide vane is separated from the small guide vane, and when the ringing stopping function is pushed back, the ringing stopping rod is separated from the large guide vane, so that the large guide vane is contacted with the small guide vane, and the ringing function is started.
In summary, according to the high-precision clock alarm starting point calibration method provided by the invention, the traditional manual operation is replaced by a mode of driving the poking needle rod on the clock movement to rotate through the motor, so that the purpose of improving the working efficiency is achieved. Meanwhile, because the rapid rotation of the motor brings great inertia force, when the calibration point of the clock movement is adjusted, the output shaft of the motor can drive the poking needle rod to rotate under the action of the inertia force, and therefore deviation is generated. Based on the method, the approximate position of the calibration point is found at a higher speed, and the calibration point is switched to rotate to the calibration point at a lower speed when the calibration point is next approached, so that manual operation and manual judgment are not needed, and the calibration precision is improved while the quick calibration and intelligent adjustment are realized.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
