Background technique

The current watch is generally adjusted manually when the pointer is adjusted. It is necessary to observe the surface with the naked eye and then rotate the pointer to the desired position. In order to liberate the user, there is gradually a watch that can be automatically adjusted. The adjustment form is based on first determining the position of the physical pointer of the watch. At present, the mainstream is to use the camera to photograph the surface of the watch, and to determine the position of the pointer by means of image recognition. Then in order to adjust the time, then turn the pointer to the corresponding time position.

technical problem

The drawback of the watch is that it is difficult to judge the physical position of the pointer relative to the dial. The present invention provides an open circuit on the dial, and the position of the metal pointer is detected by whether the open circuit is closed. The specific technical solution of the present invention is as follows.

The watch includes a surface, the surface is provided with an opening; the watch movement is provided with a flexible resettable conductor at a position facing the opening of the surface; the length of the conductor protruding from the opening is greater than any pointer distance Height of the surface (the conductor may extend from the movement when the watch automatic timing procedure is initiated, the processor may control the conductor to retract, extend and retract after exiting the automatic timing procedure The self-contained motor or the crank slider mechanism is implemented; the conductor is in an open circuit, and when the watch automatically synchronizes the program, when the pointer contacts the conductor, the open circuit is closed, the processor After detecting the closing of the open circuit, the processor controls the driving motor of the pointer of the conductor to drive the pointer to rotate by a rotation threshold and then stops to the preset position.

The conductor is arranged in a rod shape and protrudes from the outlet. When the pointer rotates to the position where the conductor is located, the pointer contacts the conductor, the open circuit becomes a closed circuit, and the processor drives the pointer to rotate the threshold and stops, the stop The position is the preset position, and the preset position may be the zero position.

Of course, when starting the automatic watch timing program, there may be a pointer that has touched the conductor and the circuit composed of the conductor and the pointer has formed a loop. In this case, the influence needs to be eliminated first.

When the watch automatic timing program is started, if the processor detects that the open circuit has been closed, the processor drives the first pointer to rotate by an angle threshold according to a preset sequence, and if the open circuit is still closed at this time, Then, the processor drives the second pointer to rotate the angle threshold according to a preset sequence. If the open circuit is still in the closed state, the processor drives the third pointer to rotate the angle threshold in a preset order.

When the watch automatic time synchronization program is started, the processor controls all the hands to stop rotating, and operates all the pointers to the preset position according to a preset program.

The current time is obtained when the watch receives the current time by radio waves or the current time acquired by the bound mobile terminal.

At the current time, the processor sets the adjusted angular velocity ωi of each pointer (i can be a minute hand, an hour hand, and a second hand), and stores the angular velocity Ωi of each pointer during normal walking, and calculates the preset position of each pointer. Angle B from the current time position;

As shown in Figure 1, the preset position of a pointer is set at 0 (11 position), and the position of the pointer should be at the 12 position at the current time acquired by the watch. When the time t is adjusted, the current accurate time should be The position is 13, thus:

11 position to 13 position angle A = ωi * t;

11 position to 12 position angle B = ωi * t1; where t1 is the time when the pointer is rotated to the current time position; B and ωi are known, so t1 = B / ωi is known;

Thus, the angular difference between the 12 position and the 13 position is: A - B = ωi * (t - t1);

The position from 12 to 13 is the angle that the current time and the current accurate time the second hand walks during the entire adjustment time t, so A-B=Ωi* t;

From the above calculation formula, the angle A=B*ωi/(ωi−Ωi) that the pointer needs to rotate when the pointer is adjusted to the current accurate time can be obtained.

After turning the angle A described above, the pointer homing program controls the pointer that has been timed to normally travel at a speed of Ωi.

By this method, the user only needs to activate the function of the automatic timekeeping of the watch, and the automatic timing can be realized, no manual operation is required, and the physical position where the pointer is currently located is not needed.

Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that The technical solutions described in the foregoing embodiments may be modified, or some or all of the technical features may be equivalently replaced; and the modifications or substitutions do not deviate from the technical solutions of the embodiments of the present invention. range.
