Embodiment 1

[0025] The product of the present invention is a Beidou automatic time service watch, a dial and a watch strap. The dial is provided with a display screen, and the dial also includes a Beidou chip, a clock chip and an MCU. After taking the watch, the clock chip of the watch performs the first time service, and the MCU records the number of time services as T (T=1). After time N (N=720H), the clock chip performs the second time service, and the MCU records the number of time services as T +1 (T=1), at this time, the MCU records the time difference between the clock chip and the Beidou satellite in the T+1 time service is P (P=5 seconds), that is, 5 seconds slower.

[0026] After time N (N=720H), the clock chip is about to perform the third time service, and the MCU records the number of time service as T+2 (T=1). At this time, the MCU controls the clock chip to set the clock to Adjust the speed for 5 seconds, and display the value directly on the display, and then perform the t...

Embodiment 2

[0029] The difference from Example 1 is that after several consecutive MCU automatic time corrections, when the MCU compares the time difference P between the clock chip and the Beidou satellite for less than 1 second, the time difference between the two time services changes from N to N+320h (720H +500h). Thereby reducing the power consumption of the watch.

Abstract

The invention discloses a Beidou disciplined time service method characterized by comprising a step 1 of acquiring Beidou satellite time by using a chip, performing time service, marking the number of times of the time service as T; a step 2 of performing time service on the chip again after time N, and marking the number of times of the time service as T+1; a step 3 of computing the time error of the chip within the time N; and a step 4 of automatically adding, when time service is performed on the chip for the (T+2)th times after time N, the computed time error to the display end of the chip so as to achieve a time self-correction method in a non-satellite-time-service mode. The method may reduce power consumption of satellite time service and increases time accuracy.

Description

technical field [0001] The invention relates to an anti-theft device, in particular to an anti-theft device for personal belongings and an anti-theft method thereof. Background technique [0002] Beidou timing refers to the Beidou products, regularly communicate with Beidou satellites to check the time. However, in the existing Beidou equipment, there are still certain errors due to reasons such as crystal oscillators and electronic components. As time goes by, the errors become larger and larger, and satellite time calibration must be performed again. However, in the existing equipment, there is an automatic time service device, but when it is time service, because the time deviation is too large, the time service operation occurs regularly and frequently, so it will cause large power consumption and large errors during time service, which will cause problems. Customers feel that the product experience is not strong. [0003] Through the novelty search, we found some dome...
