Step 3: The processor again controls the motor to drive the any pointer to rotate the preset angle to a preset position.

Further, between step 1 and step 2, step S1 is further included:

When the processor detects that the circuit has formed a loop, the processor drives the first pointer to rotate by an angle threshold according to a preset pointer order. If the circuit is still in a loop state, the processor follows the preset. The second pointer is sequentially driven to rotate the angle threshold. If the circuit is still in a loop state, the processor drives the third pointer to rotate the angle threshold according to a preset sequence; if the circuit is still in a loop state, then The processor again drives the first pointer to rotate by an angle threshold in a preset sequence of pointers, and so on, until the processor detects that the loop is open.

Further, in the step S1, only the first pointer and the second pointer are omitted, and the third pointer is omitted.

Further, the capacitive touch block is a segment of a circle that is concentric with the surface, and during the rotation of the at least one metal pointer, when the at least one metal pointer is in the capacitive touch block Directly above, the at least one metal pointer can cooperate with the capacitive touch block to form a capacitance such that the circuit forms a loop.

Further, the angle of the ring-shaped capacitive touch block is A when viewed from the center of the literal; the capacitive touch block includes the loop start 101, the loop center line, and the loop end point when viewed from the clockwise direction 102. The circuit forms a loop when the at least one metal pointer is between the loop start 101 and the loop end 102.

Further, the loop center line coincides with the zero point position of the literal surface.

Further, the preset angle is A/2. In the third step, the processor controls the motor to drive the any pointer to rotate the preset angle A/2 counterclockwise to a preset position of zero.

Further, the preset angle is 6 degrees.

Further, the angle threshold is equal to the angle A.

Embodiments of the invention

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be embodied in a variety of forms and should not be construed as being limited to the examples set forth herein; rather, these embodiments are provided to make the invention more comprehensive and complete, and the embodiments of the example embodiments are fully conveyed. To those skilled in the art. The drawings are only schematic representations of the invention and are not necessarily to scale. The same reference numerals in the drawings denote the same or similar parts, and the repeated description thereof will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are set forth However, one skilled in the art will appreciate that the technical solution of the present invention may be practiced, and one or more of the specific details may be omitted, or other methods, components, devices, steps, etc. may be employed. In other instances, well-known structures, methods, apparatus, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

As shown in FIG. 1, the watch includes a surface 1, a capacitive touch block 2, a minute hand 3, an hour hand 4, and/or an hour hand; during the rotation of the hand, there may be a track 5 of the hand detection point.

The schematic diagram is only for convenience of illustration. Only the hour and minute hands are drawn. In fact, it is also true for other possible needles such as the second hand. This method is not limited to the number or form of the hands. Only the needle material is required to be a common metal material, metal. The material allows the pointer to form a capacitor with the capacitive touch block.

As shown in FIG. 2, the angle 103 of the ring-shaped capacitive touch block is A from the center of the literal surface; the capacitive touch block FPC has a loop start 101, a loop center line, and a loop end 102. The circuit forms a loop when the at least one metal pointer is between the loop start 101 and the loop end 102. When in an area outside the capacitive touch block, the metal pointer and the capacitive touch block do not cause the circuit to form a loop.

When the metal pointer is turned directly above the FPC, a low level signal is triggered and the processor can detect the signal to determine that the circuit is forming a loop. When the low level signal disappears, the loop opens.

At the beginning of the test, if there is any pointer just above the capacitive touch block, then the circuit is the loop at the beginning. At this time, it is necessary to eliminate this effect. The elimination method is:

The angle threshold described above may be exactly the angle of the ring-shaped capacitive touch block. In this way, the pointer just on the capacitive touch block can be completely moved out of the capacitive touch block.

During the detection, after the detection indicates that the circuit is the influence of the circuit, the processor continues to control the motor to drive the metal pointer for rotation. Here you can set a sequence, such as first hour hand, second minute hand and second hand, of course, can also be other order, first adjust a pointer and then adjust the rest of the pointer.

The processor controls any of the pointers to continue to rotate when the circuit forms a loop; the processor controls the motor to stop driving any of the pointers when the loop is open; the processor The motor is again controlled to drive any of the hands to rotate the preset angle to a preset position.
