The existing technology of using intelligent circuit modules to calibrate mechanical clocks has the following disadvantages:

[0004] 1. The clock of the intelligent circuit module is powered by a battery. When the battery is dead, the clock of the intelligent circuit module will no longer work. If the time is calibrated directly after charging or replacing the battery, the time will be confused. Mechanical watches generally have the characteristics of stable and accurate running time. If the time is confused due to a dead battery, the properties of the mechanical watch will be destroyed.

[0032] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings, but these embodiments do not limit the present invention. Structural, methodological, or functional changes made by ordinary technicians in the field based on these embodiments are all included in the protection scope of the present invention.

[0033] like Figure 1As shown, a mechanical smart watch of the present invention comprises a dial, an intelligent circuit module arranged below the dial and capable of recording user information and feeding back to the user, and a pointer arranged on the dial, wherein the intelligent circuit module comprises a clock unit for generating a one-second interval and maintaining continuous counting;

[0034] The intelligent circuit module includes an electrically connected PCB circuit board, on which one or more sensors and a wireless transmission module may be provided, the one or more sensors being used to record user information, and may be sensors for recording sleep information, sensors for recording exercise information, sensors for recording heartbeats, or sensors for measuring blood pressure, and the wireless transmission module may be a low-power Bluetooth module, and the intelligent circuit module is connected to the mobile terminal via the low-power Bluetooth module to transmit and receive user data information;

[0035] A mechanical movement is provided below the dial to drive the pointer to rotate. The power generated by the left-right swing of the automatic disk at the bottom of the mechanical movement drives the clockwork to generate energy. The pointers include an hour hand 10, a minute hand 20 and a second hand 30. The hour hand 10, the minute hand 20 and the second hand 30 are coaxially arranged. Photoelectric switches are respectively provided at the positions where the hour hand 10, the minute hand 20 and the second hand 30 pass through the paths. A first photoelectric switch 1 is provided at the position where the hour hand 10 points to 1 o'clock. The first photoelectric switch 1 changes in response to the light change when the hour hand 10 passes by. The time interval between the hour hand 10 passing through the first photoelectric switch 1 is 12 hours. At 3, 6, The second photoelectric switch 2, the third photoelectric switch 3, the fourth photoelectric switch 4 and the fifth photoelectric switch 5 are arranged at the four time positions 9 and 12. The minute hand 20 and the second hand 30 share the second photoelectric switch 2, the third photoelectric switch 3, the fourth photoelectric switch 4 and the fifth photoelectric switch 5. The minute hand 20 and the second hand 30 have different time intervals for running, so as to distinguish the minute hand 20 and the second hand 30, obtain and confirm the current time, each photoelectric switch is connected to the intelligent circuit module, and the current time is compared with the clock unit of the intelligent circuit module by inputting an electrical signal to the intelligent circuit module, so as to realize the timing calibration of the clock unit of the intelligent circuit module;

[0036] like Figure 2 As shown, a power supply is also arranged below the dial, and the power supply is connected to the intelligent circuit module and the photoelectric switch. A power management unit (PMU) is arranged between the power supply, the intelligent circuit module and the photoelectric switch. The power supply is connected to the intelligent circuit module and the photoelectric switch through the power management unit, so as to achieve higher power conversion efficiency and lower power consumption.

[0037] The specific operation mode of this embodiment is as follows: first, the hour hand 10 can be distinguished by the photoelectric switch 1 at 1 o'clock. The hour hand 10 passes through the photoelectric switch 1, and the photoelectric switch 1 inputs a low level to the intelligent circuit module to obtain the current time 1:00:00. Then, the minute hand 20 and the second hand 30 are distinguished by the directions of 3, 6, and 9 o'clock. The running speed of the minute hand 20 is slower than that of the second hand 30. It takes 15 minutes for the minute hand 20 to pass through the next photoelectric switch, while the running speed of the second hand 30 is fast, and the photoelectric switch will be continuously interrupted. When the minute hand 20 passes through the second photoelectric switch 2, the second photoelectric switch 2 continuously inputs a low level to the intelligent circuit module within one minute. At the same time, the second hand 30 passes through the third photoelectric switch 3 and the fourth photoelectric switch 4, and respectively inputs a low level to the intelligent circuit module. The intelligent circuit module recognizes that the position of each low-level signal input is different, distinguishes the response position of the minute hand 20 and the second hand 30, and thus obtains the time information, that is, the current time of the dial. This time corresponds to the same fixed time set in the intelligent circuit module. This time information is extracted at this fixed time to calibrate the clock unit.

[0038] In this embodiment, one photoelectric switch is set to correspond to the hour hand 10, and four photoelectric switches are set to correspond to the minute hand 20 and the second hand 30. The time calibrated within 24 hours corresponds to the moment position set at the photoelectric switch 1. The time interval between the hour hand 10 passing through the photoelectric switch 1 twice is 12 hours, so there are 3 moments of calibration time that can be set every 12 hours, that is, there are 6 calibration opportunities.

[0039] Optionally, multiple corresponding hour hand photoelectric switches can be set to obtain time information at multiple moments. By obtaining the time information transmitted by the photoelectric switch and comparing it with the clock unit of the intelligent circuit module, the time difference is obtained, and the clock unit is calibrated with this time difference.

[0040] The present invention adds a photoelectric switch to the path of a mechanical watch hand, identifies the mechanical watch hand time by the electrical level of the photoelectric switch, and calibrates the clock unit of the intelligent circuit module. While combining the intelligent circuit module with a traditional mechanical dial, it ensures that there is no need to connect to a mobile terminal for time calibration when replacing the battery of the intelligent circuit module.

[0041] A method for calibrating an MCU clock using a mechanical clock comprises the following steps:

[0042] S1, setting a photoelectric switch at the hour hand running position, the photoelectric switch only responds to the hour hand running to confirm whether it has entered the calibration time;

[0043] S2, a plurality of split-second photoelectric switches are arranged at the running positions of the minute hand and the second hand, the split-second photoelectric switches respond to the running of the minute hand and the second hand, and the time interval of the running of the second hand is shorter than the time interval of the running of the minute hand, so as to distinguish the second hand from the minute hand;

[0044] S3, when the photoelectric switch detects the passing of the hour hand, an electrical signal is input to the intelligent circuit module;

[0045] S4, when the minute hand moves to the detection position of the split-second photoelectric switch, the second hand is at the 12 o'clock position, and the split-second photoelectric switch inputs an electrical signal to the intelligent circuit module, thereby confirming the minute hand time at the calibration time. In the same minute, when the second hand passes another split-second photoelectric switch, the split-second photoelectric switch inputs an electrical signal to the intelligent circuit module, thereby confirming the second hand time at the calibration time;

[0046] S5. The intelligent circuit module obtains the calibration time through the electrical signals transmitted by the hour photoelectric switch and the minute-second photoelectric switch, and compares it with the internal clock of the intelligent circuit module to complete the time calibration.

[0047] In this embodiment, the hour photoelectric switch is located at the 1 time direction position, that is, photoelectric switch 1; the minute and second photoelectric switches are located at the 3, 6, 9, and 12 time direction positions, that is, photoelectric switch 2, photoelectric switch 3, photoelectric switch 4, and photoelectric switch 5.

[0048] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
