[0019] The present invention will be further described in detail below through the accompanying drawings and examples.

[0020] The embodiment of the present invention provides a watch with a current-carrying spiral loop that passes a cosine current, such as Figure 1-3As shown, it includes a watch head 1 and a watch strap 2. A magnetic slider 3 is fixedly disposed at the lower end of the watch head 1. The magnetic slider 3 includes a magnetic sheet 31 and a magnetic ring 32. A vertical bar 33 is disposed between the magnetic sheet 31 and the magnetic ring 32 to connect the two. The magnetic sheet 31, the magnetic ring 32 and the vertical bar 33 are integrally formed. The watch strap 2 is a hollow circular ring. A sliding groove 21 is provided within a range of 90 to 270 degrees on the outer surface of the watch strap 2. A ball bearing rail 4 is disposed on the inner surface of the watch strap 2. The magnetic ring 32 is disposed in the watch strap 2 and is slidably connected to the ball bearing rail 4. A coil sleeve 5 is disposed in the watch strap 2. The coil sleeve 5 wraps around a current-carrying spiral ring. The coil sleeve 5 passes through the magnetic ring 32. The vertical bar 33 is interactively connected to the sliding groove 32. The magnetic sheet 31 is located outside the watch strap 2. It should be noted that a battery and an AC inverter module are provided at the portion of the watch strap 2 where the sliding groove 21 is not provided (the prior art will not be described in detail).

[0021] Electromagnets 6 are provided at both ends of the sliding groove 21. The magnetic slider 3 itself is magnetic, with the left side being N level and the right side being S level.

[0022] Working process: When the user presses the switch, the current-carrying spiral ring passes cosine alternating current. The current amplitude is 0.00422A, the current frequency is 1.61HZ, and the current function is:

[0023] I(t)=0.00422cos(10.16t)

[0024] Generate a circular magnetic field, which will generate a magnetic force around the current-carrying spiral ring on the magnetic slider 3. The direction of the magnetic force is always consistent with the movement direction of the magnetic slider 3 and the meter head 1. At the same time, the electromagnet at the starting position will pass direct current to make the end of the electromagnet 6 that contacts the magnetic slider 3 become the N pole. The contact end of the electromagnet 6 at the end point is also N-level to generate initial power for the magnetic slider 3. Then the magnetic slider 3 will move around the watch strap under the action of the magnetic field of the current-carrying spiral ring and gravity. The current-carrying spiral ring will pass a current that changes with a cosine function. Finally, the speed of the magnetic slider 3 reaching the key position is close to 0. Then the magnetic slider 3 will be adsorbed on the end point electromagnet 6, and the meter head 1 is fixed to the lower part of the watch strap 2. If you want the meter head 1 to return to the starting point, press the switch again (the switch and its internal circuit diagram are implemented in the existing technology), the electromagnet 6 will pass reverse direct current, and the current-carrying spiral ring will pass cosine alternating current. The amplitude of the current is 0.01291A, the frequency of the current is 4HZ, and the current function is:

[0025] I(t)=0.01291cos(25.13t)

[0026] When meter head 1 slides from 290 degree position on the strap to 270 degree position, the current-carrying spiral ring passes cosine alternating current, the amplitude of the current is 0.00422A, and the frequency of the current is 1.61HZ; when meter head 1 slides from 2270 degree position on the strap to 90 degree position, the current-carrying spiral ring passes cosine alternating current, the amplitude of the current is 0.01291A, and the frequency of the current is 4HZ.

[0027] The specific calculation process is as follows:

[0028] n: represents the number of turns around the coil, in turns / m. I: is the current, in amperes (A). r: is the radius of the ring, in meters (m). This formula is used to calculate the magnetic field strength H generated by the current I in a circular coil. The magnetic induction strength of a circular coil is:

[0029]

[0030] μ: is the magnetic permeability of the material, in units of Henry per meter (H / m), which indicates the material's ability to respond to magnetic fields. H: is the magnetic field strength calculated previously. Substitute B into the armature's magnetic force formula:

[0031]

[0032] S: is the effective area, in square meters (m2), usually referring to the area intersecting with the magnetic field. This formula is used to calculate the magnetic force acting on a conductor.

[0033]

[0034] Simplified to:

[0035]

[0036] Assume that the expression of current I(t) changing with time is:

[0037] I(t)=I0cos(ωt)

[0038] Substituting the value of the cosine current into

[0039]

[0040] The resultant force and the tangential gravity component can be expressed as:

[0041] F net (t) = F magnetic (t)-F tangential (t)

[0042] in:

[0043] F tangential(t)=mgcos(θ)(90°≤θ≤270°)

[0044] If the current is in the opposite direction:

[0045] F net (t)=-F magnetic (t)-F tangential (t)

[0046] The acceleration a is:

[0047]

[0048] Integrate the acceleration a(t) to get the velocity. According to the relationship between acceleration and time:

[0049]

[0050] Since v0 is 0, after substituting the parameters, we get the final expression of velocity changing with time:

[0051]

[0052]

[0053]

[0054] Matlab uses these parameters to calculate the movement changes of the watch during the reversal process (a physical system involving magnetism and gravity). The purpose is to use a coil system to control the current to generate a magnetic field to exert force on the object, thereby adjusting its motion state. The goal is to make the object move from the initial position to the 270-degree position with a speed close to zero, ensuring that the object can reach the target position smoothly and as quickly as possible. The code then updates the speed and angle here by the Euler method to simulate the dynamic motion process of the object under the action of magnetism and gravity. During the entire simulation process, the code continuously calculates the force, acceleration, velocity and position of the object at each time step through these formulas to obtain the motion trajectory of the object. In order to find the optimal current amplitude and period, these parameters are gradually adjusted by using the simulated annealing algorithm to minimize the speed of the object when it reaches the 270-degree position. By adjusting the amplitude and period of the current, the code is actually controlling the interaction between magnetism and gravity, thereby changing the motion trajectory of the object so that it can reach a stable state when it reaches the target position. This optimization process includes the calculation of multiple interacting forces in the physical system. The code can simulate the real motion state of the object under the combined action of electromagnetic force and gravity. These calculations provide accurate objective function values ​​for the simulated annealing algorithm, so that the optimization process can be carried out effectively, and finally find the best system parameter combination that can enable the object to reach the 270-degree position smoothly. In order to achieve the goal of reaching the target position smoothly and quickly, the amplitude and frequency of the cosine current need to be adjusted to achieve this goal.

[0055] The code uses simulated annealing, a global optimization algorithm based on the physical annealing process. The simulated annealing algorithm is inspired by the thermodynamic annealing process in physics, in which metals or other materials are heated at high temperatures and then gradually cooled down to make their internal structure tend to the lowest energy state, thereby achieving the optimal crystal structure. In the code, the goal of simulated annealing is to find the optimal parameters of the system by gradually lowering the temperature so that the speed of the block is minimized when it reaches the 270 degree position. This process involves many randomized choices to prevent the algorithm from falling into the local optimal solution and missing the global optimal solution.

[0056] This is the optimal current situation and the ideal time to arrive from the 90 degree to 270 degree position:

[0057] Optimum current amplitude I0: 0.00422A

[0058] Optimum current cycle: 0.62 seconds

[0059] The shortest time to 270 degrees: 0.17 seconds

[0060] This is the optimal current flow from 270 degrees to 90 degrees and the ideal time to reach it:

[0061] Optimum current amplitude I0: 0.01291A

[0062] Optimum current cycle: 0.25 seconds

[0063] Minimum time at 90 degrees: 0.12000 seconds

[0064] Speed ​​at 90 degrees: -0.027m / s
