Timing method and timing system

Abstract

The invention provides a timing method. The timing method comprises the following steps: first, a correction signal receiving device sends a standard time signal to an electronic timing device; followingly, the electronic timing device calculates a new corrected value X1 according to the standard time signal; and eventually, the electronic timing device automatically corrects according to the new corrected value X1, and accomplishes correction. Namely, the annoyance when timing and time regulating by hands are needed regularly and the inconvenience brought about by serious inaccurate timekeeping can be reduced in a using process; and one-way connection is adopted for both the electronic timing device and the correction signal receiving device, only one time of connecting and standard time signal receiving is needed to accomplish time correction automatically, repeated connection and data transmission with the correction signal receiving device are not needed, correction time delay and transmission data signal interference are completely avoided, correction speed is quicker, and data are more accurate.

Description

【Technical field】 [0001] The invention belongs to the technical field of clocks and watches, and in particular relates to a time calibration method and a time calibration system. 【Background technique】 [0002] At present, due to the frequency error of the quartz crystal oscillator in the ordinary quartz watches on the market, at a normal temperature of 25°C, most of the monthly time difference of the clocks and watches is 20 seconds to 30 seconds or more; The monthly difference in travel time will be even greater. In order to correct the frequency error of the crystal oscillator and improve the timing accuracy of the watch, it is usually necessary to configure different capacitors for different crystal oscillators, which brings troubles to production. [0003] For this reason, some manufacturers have developed and researched some technical methods and equipment for solving the above problems, but these methods and equipment need to repeatedly establish connections between ...
