A Relay Type Indoor Clock Time Calibration Method and Indoor Clock Time Calibration System

Abstract

The invention discloses a relay type indoor clock timing method and an indoor clock timing system. The system comprises an indoor clock and one or more relay devices arranged indoors. The indoor clock is used for determining to stop time travelling of a pointer at a dial plate temporarily to enter a timing period when clock traveling time (Tg) arrives at a clock timing trigger point location (Tc). Each relay device is used for obtaining a network timing signal, carrying out coding on the network timing signal, and forwarding a timing information code generated by the coding to the indoor clock or forwarding timing information code to other relay devices; and other relay devices transmit the timing information code to other relay devices. The indoor clock is used for receiving the timing information code, carrying out error prevention and misoperation prevention code checking on the timing information code, calculating an indoor clock travelling deviation (deltaT1) based on the timing information code, and driving a transmission mechanism in a clock movement to execute a corresponding action based on the indoor clock travelling deviation (deltaT1), so that the indoor clock traveling time (Tg) is corrected to be standard time (Ts).

Description

technical field [0001] The invention relates to the technical field of clocks and watches, and more specifically, relates to a relay-type 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 defect...

AI Technical Summary

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
