Description
Technical Field
The invention relates to the technical field of sundial time correction, in particular to a method for acquiring sundial time difference by scanning codes.
Background
All sundial times are true sunlights, which are different from the standard times used in daily life in concept and value. The Shanghai astronomical desk researcher Zhao Ming teacher published in 2006 in the book "celestial body metrology introduction" of the Chinese academy of sciences indicates that the time system established based on the rotation of the earth is continuous but non-uniform, and the overall trend is slow, while the time system established based on the atomic clock is continuous and uniform, but cannot be completely applicable to the instinct work and rest rhythm of people from Taiyang east rising West. Therefore, the international time standards organization promises a daily standard time system that coordinates universal time. The coordinated world time divides the world into 24 standard time zones, wherein the Chinese national standard time is located in the east 8 zone, namely the Beijing time which we often say. The conversion from the sundial time to the Beijing time requires two steps, firstly, the local true solar time measured by the sundial needs to be converted into the local mean solar time according to the average time difference, and then the local mean solar time is converted into the Beijing time according to the time difference between the sundial installation ground meridian and the east eight area central meridian, namely: the Beijing time is the sundial time + the average time difference + the transit time difference. Wherein the transit time difference is 8-sundial longitude/15 hours, and the mean time difference is often given by astronomical observational statistics according to a large number of astronomical observational statistics. The moveout is due to the earth's orbital inclination and orbital eccentricity. The change of the included angle between the earth rotation axis and the revolution orbit surface can enable the sundial time to generate oscillation of 7.66 minutes in one year, the elliptical revolution orbit of the earth can enable the sundial time to generate oscillation of 9.87 minutes in one year, and the two effects are superposed to enable the sundial time to reach the deviation of more than ten minutes. The calculation of the mean time difference is very complex and is usually found using a plot of the number of years of the mean time difference minutes as shown in figure 2.
The earth rotates for one circle in 24 hours, the sun rotates for 1 degree every 4 minutes in the sky, the opening angle of the surface of the sun is about 0.5 degree, the time measurement precision of a general sundial can be about 1 minute, and the time difference and the transit time difference are also often expressed as correction values in minutes. The precision of the clock used in daily life of people is generally within 1 second, so that the actual timing significance of a sundial is not large, more than the real time significance is marked around the life of people as a symbolic representation of historical civilization, the cultural effect of witnessing the objective years is continuously exerted, people are led to exclamation time-day-Perilla frutescens , and the significance of thinking of transient life is further realized. With the development of scientific and economic efficiency and the revival of traditional culture in China, particularly twenty-four solar terms in China are listed in related catalogues of the united nations as non-material cultural heritages of human beings, sundial and the like show more and more civilized sign landscapes of ancient technological level in China. Because sundials measure local sun time, and time difference exists between the sundials and the current standard time system, although some sundials also mark time difference curve charts, the doorsill is too high for the ordinary people, so that certain difficulty is brought to people to really know and use the sundials, and the shortages of the popular science work of the time knowledge system are reflected.
Disclosure of Invention
In order to solve the problems, the invention provides a sundial time difference code scanning obtaining method, and aims to provide a simple method for correcting the sundial time to the national standard time, namely Beijing time.
In order to realize the purpose, the method for acquiring the sundial time difference code scanning provided by the invention is realized as follows:

2. opening code scanning application software of the intelligent mobile terminal;
3. scanning the time difference two-dimensional code;
4. submitting a time difference query request;
5. calculating the accurate time difference of the sundial;
6. and outputting a sundial time difference query result.
Furthermore, the two-dimensional code in the step 1 encodes link address information pointing to a sundial time difference query cloud service.
Furthermore, the smart mobile terminal in step 2 may be a smart phone or a tablet computer with a networking function, and the code scanning application software may be a WeChat or Paibao application software with a two-dimensional code scanning function.
Furthermore, the time difference query request in the step 4 includes geodetic coordinate data information of a sundial installation place, and the submitting action is automatically completed by code scanning application software.
Furthermore, the accurate time difference of the sundial in the step 5 comprises two sets of time difference correction data of time difference and time difference of the national standard time, and the calculation action is remotely completed by a cloud service.
