Problems solved by technology

[0003] Among them, the technical defect of GPS timing lies in that: the satellite navigation antenna needs to be erected outdoors and connected to the indoor clock through cables to transmit timing signals, resulting in messy indoor wiring;
[0004] The technical defect of radio wave timing lies in: my country has a vast territory, and the timing signal sent by the BPC low-frequency time code broadcasting station established in Shangqiu, Henan Province cannot cover all parts of the country, and the application range of radio wave timing technology is limited;
[0005] The defect of the timing technology of the master clock time synchronization system is that the system is a wired synchronous control system, and the time signal or timing signal adopts a wired transmission method, which not only makes indoor wiring difficult, but also affects the cleanliness and aesthetics of the indoor environment

Embodiment 1

[0054] The present embodiment provides a kind of point-to-point indoor clock timing system, and the structure of the point-to-point indoor clock timing system will be described in detail below:

[0055] Such as figure 1 As shown, the point-to-point indoor clock timing system includes a mobile terminal 100, a meteorological department server 300, a time service center 200, and an indoor clock 300. The mobile terminal 100 establishes communication with the meteorological department server 300, the time service center 200, and the indoor clock 300 in a wireless communication manner. .

[0056] Wherein, the mobile terminal 100 is used to obtain the timing signal from the timing center 200, and forward the timing information to the indoor clock 300 after packaging the timing information;

[0057] The indoor clock 300 is used to receive data packets, decode the data packets to obtain the standard time Ts, compare the standard time Ts with the travel time Tg of the indoor clock, and...

Embodiment 2

[0074] The processing flow of the point-to-point indoor clock timing method provided in this embodiment is shown in Figure 4, including the following processing steps:

[0075] Step 101 , when the indoor clock 300 is powered on, perform an initialization operation of the indoor clock.

[0076] The indoor clock initialization operation process of the present invention includes the following sub-steps:

[0077] 1011. Adjust the pointer of the indoor clock 300 when it leaves the factory and stay at the initial time Tt. The clock is equipped with a time timer 307 that can keep time continuously, and what is recorded is the internal time T of the clock. C , the initialization process first calculates the indoor clock initialization correction time Tj, wherein, Tj=Tt+Tc;

[0078] 1012. Drive the transmission mechanism in the clock movement (303) to perform corresponding actions to rotate the dial pointer of the indoor clock from the initial position Tt to the dial position correspo...

Abstract

The invention discloses a point-to-point indoor clock timing method and an indoor clock timing system. The system comprises a mobile terminal and an indoor clock that carry out wireless communication mutually. The mobile terminal is used for making a request of obtaining a timing signal to a time service center, packaging the obtained timing information, and forwarding the information to the indoor clock. The indoor clock is used for receiving a data packet carrying standard time (Ts), decoding the data packet to obtain the standard time (Ts), comparing the standard time (Ts) with indoor clock travel time (Tg), calculating an indoor clock travel time deviation (deltaT1), and driving a driving mechanism in a clock movement correspondingly based on the indoor clock travel time deviation (deltaT1), so that the indoor clock travel time (Tg) is calibrated into the standard time (Ts). According to the invention, the indoor clock timing scheme is realized based on a wireless communication technology. A problem that radio wave signals can not cover the whole country can be solved; the cable restriction is eliminated; and the cleanness and elegance of the indoor environment are ensured.

Description

technical field [0001] The invention relates to the technical field of clocks and watches, and more specifically relates to a point-to-point indoor clock time calibration method and an indoor clock time calibration system. Background technique [0002] Since the frequency of the quartz crystal is easily affected by the ambient temperature, and the quartz crystal itself will age with time, the output frequency will drift, so the quartz clock will inevitably experience time errors as the service life increases. At present, in the watch industry, common indoor clock time calibration solutions include GPS time calibration, radio wave time calibration, and master clock time synchronization system time calibration. [0003] Among them, the technical defect of GPS timing lies in that: the satellite navigation antenna needs to be erected outdoors and connected to the indoor clock through cables to transmit timing signals, resulting in messy indoor wiring; [0004] The technical def...
