Description

Construction Method of Analemma Sundial

The present invention relates to a method for constructing an analemma sundial, and more particularly, an analemma sundial that can be designed by reflecting mean solar time and standard time by making the gnomon move using the 8-character movement of the sun (Analemma). It's about construction methods.

The sundial, which measures the time by the shadow of the sun, is an astronomical observation device that measures the true solar time of the area by reading the time of the position of the shadow of the gnomon by drawing time lines on the time plane where the shadow of the fixed zodiac generally occurs.

However, today, since standard time is based on the standard meridian of a region or country, an error occurs in the time of a sundial and a general clock, and for this reason, a sundial (analemma sundial) that can measure standard time using the eight-character movement of the sun has recently been developed. has been developed and used.

As an example of the analemma sundial as described above, a sundial capable of measuring standard time (hereinafter referred to as 'patent document') disclosed in Patent Registration No. 1512268 is disclosed.

The patent document has an '8' shape that reflects the change in the equation of time from the midday time of the area to be measured, and has an analemma date scale line with a moon point indicating the point corresponding to the first day of each month and the south and south A date scale plate having a north-south line connecting the north, and located in an elliptical shape centered on the date scale plate, corrects the value obtained by converting the longitude difference, which is the difference between the longitude of the installation area and the standard meridian longitude, into time to correct the time in standard time It is positioned in an elliptical shape centered on the standard time clock displaying a point and the date scale plate to display a time point at each half-division without longitude difference correction, and a time point so that a pentagram is located to the north of the north-south line. When the time confirmation unit is located on the analemma date grid line corresponding to the measurement date, the time corresponding to the position of the standard time time board indicated by the shadow of the time confirmation unit is the current standard time. It is measured by time, and when the time confirmation unit is located on the north-south line corresponding to the measurement date, the time corresponding to the position of the true solar time clock indicated by the shadow of the time confirmation unit is measured as the current true solar time.

In order to construct the analemma sundial of the patent document, a worker should set a reference line and a reference point in the field, measure the position of the time point, north-south direction point, and date dial based on this, and then construct a time plate according to the measured position. Due to this process, it takes a long time to construct the analemma sundial, and at the same time, there is a difficulty in requiring skilled workers capable of constructing the analemma sundial.

Therefore, it is required to develop an improved analemma sundial construction method so that it can be constructed simply and quickly without a complicated drawing process by workers in the field.
