Description

The invention relates to time devices with digital indication of the current time, calendar and other additional chronometric information.

The famous mechanical watch brand Martin Braun, model EOS 42 B, made in Switzerland. This watch has hour and minute hands, showing the current time on the 12-hour dial, the date of the day is displayed in the window of the dial. The peculiarity of this watch is that it indicates the sunrise and sunset using the two arrows. On the left side of the dial, the arrow indicates the sunrise in numbers from 5 to 8 (hours), and on the right side, the other arrow shows the sunset in numbers from 17 to 20 (hours). Indications of sunrise and sunset are true only at certain coordinates on the terrain (depends on the latitude and longitude of the terrain point). No matter where the clock is supplied, each disc will have its own disc with programmed coordinates.

The disadvantages of such watches include the lack of information on the dial about the position of the sun in the sky from sunrise to sunset.

Known globe watches, (Patent of the Russian Federation No. 2278407, IPC G04B19 / 22, G09B27 / 08, publ. 06/20/2005), with an indication of international and local time, the position of the day, night, twilight and the Sun, containing the globe and clockwork, transparent spherical shell with a half shaft and gear.

The disadvantages of the design of the globe-clock include its low resolution with respect to a specific point on the globe, for example, the city of Penza can be noted with a large error on the globe, and hence the large error in determining the time of sunrise, sunset and other chronometric information, in addition , information of the position of the Sun above the horizon in this invention is missing.

The closest in technical essence to the claimed invention relates to a chronometer for determining the time of sunrise and sunset (Patent of the Russian Federation No. 2225632, IPC G04B19 / 26, G04B19 / 22, publ. 10.03.2004), in addition, the position of the Sun in a specific place at the current time a certain month using the clockwise, which turns once in 24 hours, and a fixed or rotating plate to indicate the time of sunrise and sunset on the chronometer.

A disadvantage of the known device is the inability to determine the height of the Sun above the horizon during daylight hours. In addition, sunrise and sunset are determined by these clocks with a large error, and there is no real picture of the position of the Sun in the sky.

 These shortcomings do not allow us to have an approximate picture of the position of the Sun in the sky, characterized by low accuracy of the readings of sunrise and sunset.

The objective of the invention is to approximate the actual display of the position of the Sun in the sky during daylight hours and the use of digital displays for displaying the sunrise and sunset of the Sun in a clock with digital display of calendar data.

The solution to this problem is achieved by the fact that the clock with a digital display, consisting of a time keeper, a control device, a digital indication of the year, month, day of the month, time values with a twenty-four hour scale and a backup power source connected to a time keeper connected to the device control, which is connected to digital indicators of calendar data and current time values, according to the invention, the front panel in hours is divided into upper and lower parts, in the lower parts are digital indicators of calendar data, values of the current time and digital indicators of the values of sunrise and sunset times are added. In the upper part of the front panel is the orbit of the Sun in the form of a semicircle, consisting of the Nth number of LEDs, and a narrow strip of landscape is placed below the orbit.

At the same time, a permanent storage device (ROM) has been introduced into the electronic part of the watch, in which the values of the time of sunrise and sunset for all 366 days of the year are recorded relative to a specific area determined by its geographical coordinates (latitude and longitude). The ROM also recorded the duration of the “P” burning time (for example, in seconds) of one LED in orbit for each day, which is defined as the longitude of the day “D” in seconds divided by the number of LEDs N in orbit (D: N = P), while the ROM is connected to the control device.

In addition, a subtraction scheme has been introduced into the electronic part of the clock, which calculates the difference (for example, in seconds) between the value of the current time “T” and the sunrise time “B” of the Sun, a division scheme that calculates the quotient of the difference (T - B) by the length of time Burning “P” LED. In this case, the quotient obtained from the division carries information about the number of the LED that should light up in orbit, in addition, the subtraction circuit is connected to the division circuit, the information inputs of these circuits are connected to the control device.

At the same time, two pulse counters, two decoders with keys are introduced into the electronic part of the clock, the first counter working for subtraction, the second pulses are fed to the subtraction input of which from the control device, and information about the duration of the “P” burning time is received from the control device LEDs in orbit recorded in ROM. The loan output of the first counter is connected to the counting input of the second counter working on addition, the zero input of which is connected to the control circuit, the outputs of the division circuit are connected to the information inputs of the second counter, the outputs of which are connected to two decoders with keys connected to the rows and columns LEDs of the orbit of the Sun connected in a matrix.

Introduced elements, in particular, read-only memory (ROM), in which the values of the time of sunrise and sunset for the whole year relative to a specific area determined by geographical coordinates are recorded (for the city of Penza: 53 ° 7 'north., 45 ° 1 'eastern debt.) and information on the duration of the “P” burning time of the LED in orbit. The division of the watch’s front panel into two parts, the upper part of which imitates the sky with the orbit of the Sun in the form of a semicircle on which the N-th number of LEDs are placed. The LEDs light up one after the other in accordance with the information about the time of sunrise and sunset, which are indicated on the digital indicators at the bottom of the front panel of the clock. The use of subtraction and division schemes in the electronic part of the watch allows, after resuming power supply, to restore the position of the Sun in orbit in accordance with the current time at the bottom of the watch. All of the above create new consumer properties for the proposed watch.

In FIG. 1 shows the appearance of a watch.

In FIG. 2 is a graph explaining the operation of the watch.

In FIG. 3 shows a block diagram of the electronic part of the watch.

A clock with digital indication and imitation of the sky with the Sun on diodes consists of a time keeper 1, a control device 2, a digital indication of the values of year 3, month 4, day 5 month, time 6 with a twenty-four hour scale (hours, minutes), time 7 sunrise The sun, its sunset time 8 and a backup power source 9. The power source 9 is connected to a time keeper 1, which is connected by a bi-directional bus to the control device 2, connected to digital indicators of the values of year 3, month 4, day 5 of the month, time 6, time of sunrise 7, and time of sunset 8.

A permanent memory device (ROM) 10 is introduced into the electronic part of the watch, in which tabular data on the sunrise and sunset of the sun and the burning time “P” of one LED in orbit are recorded, while the ROM 10 is connected to the control device 2, and also a circuit is connected to it 11 subtraction and division scheme 12, interconnected. In addition, two counters 13 and 14 pulses are connected to the clock, connected in series, and counter 13 works to subtract from the second pulses coming from the control device 2, and counter 14 works to add the pulses of the loan from the counter 13. The control device 2 is connected to information the inputs of the counter 13, to the counting input of which second pulses are received, the pulses from this device 2 are fed to the input of the zero setting of the counter 14, and the information inputs of the counter 14 are connected to the outputs of the division circuit 12. The outputs of the counter 14 are black of decoders 15 and 16 are connected to the rows and columns of LEDs 17 orbits the Sun, connected in a matrix.

A clock with a digital display and imitation of the sky with the sun can work in two modes: the mode of connecting the clock to the mains after de-energizing and the normal mode of operation with power from the mains (continuous round-the-clock).

Consider the mode of operation of the clock at the time of connecting them to the mains after a blackout. Suppose that the connection occurred on October 26 at 11 hours 43 minutes at the time the Sun was at its zenith (Fig. 1 and 2). At this moment, all the digital information about the values of the current time, calendar data will be displayed on the digital indicators and the time of sunrise and sunset on the digital indicators 7 and 8, which will come from the ROM 10 through the control device 2, will be highlighted. At this moment, the control device 2 in the subtraction circuit 11 will write the number 11 hours 43 minutes (the current time is “T”) to the place of “subtracted” and the number 6 hours 47 minutes (the time “B” of sunrise) will be written to the place of the “subtracted”. After the calculations, the “difference” will be equal to:

T - B = 11 h 43 min - 6 h 47 min = 4 h 56 min = 296 min × 60 s = 17760 seconds.

The "difference" T - B will be written in the division circuit 12 and divided by the number P = 560 s.

“P” is the burning time of one LED in the orbit of the Sun, for example, choose an orbit consisting of 64 LEDs. The longitude of the day November 26 is 9 hours 57 minutes, or 597 minutes, or 35820 seconds. Then the burning time of one LED in orbit will be:

P = 35820 s: 64 = 560 seconds.

The division circuit 12 will perform calculations, as a result of which the number of the LED that is lit in the orbit of the Sun at this moment is determined:

(T - B) / P = 17760 s: 560 s = 37.7, and after rounding we get 32.

The number “32” means the number of the illuminated LED in the orbit of the Sun (Fig. 2), which is recorded in the counter 14 and through the decoders 15 and 16, the 32nd LED located in the middle of the orbit — the Sun at its zenith — is lit.

 After that, the clock goes into normal mode of operation, in which the code number “P” of the burning time of one LED in the orbit of the Sun is written to the counter 13 by device 2 and second pulses from device 2 begin to subtract units from the number “P” (in the example P = 560 sec ) Counter 13 is reset after 560 seconds and the unit of “loan” is fed to the counter input of counter 14, the code in which increases by one and the next LED lights up in orbit. The control device 2 each time after resetting the counter 13 writes the time code “P” into it, the process of subtraction and addition by the counters 13 and 14 is repeated until the sunset time, after which the LED in orbit goes out until the next sunrise. The clock operates in normal mode, when the power supply is not interrupted, at the time of its resumption, the subtraction circuit 11 and the division circuit 12 begin to function, with the help of which the LED code in the orbit of the Sun is calculated, which should light up when the clock is connected to the mains.

From the above it is seen that the introduction of a set of distinctive features in the alleged invention allows, in comparison with prototypes, to display on digital indicators the exact values of the time of sunrise and sunset of the Sun in the area where the clock is located. In addition, a visual display of the movement of the Sun during the day in orbit and the placement of an image of the landscape of the area can improve the consumer properties of the watch. To tie the clock to another location, it is enough to replace the read-only memory (ROM) with tabular data.

https://lyna.info/vosxod-i-zakat-solnca/ - calculator for calculating the sunrise and sunset. An example of FIG. 1 for Moscow will look with the following data.

For the city of Moscow (55.75 ° north latitude, 37.38 ° east longitude).

October 26, 2028, Sunrise: 7 hours 24 hours; Sunset: 17 h 04 min; Longitude of the day 9 h 39 min.

The burning period of the diode "P" is: P = 9 h 39 min = 579 min × 60 s = 34740 s: 64 diodes = 543 seconds.

The calculations are made for all 366 days of the year (taking into account the leap year) and are recorded in ROM. The year is not taken into account in the calculations, since the difference in sunrise and sunset data is several minutes per decade.

Thus, the proposed digital clock with digital indication and imitation of the sky with the sun on the LEDs solves the same prototype functions, but displays accurate digital information about the sunrise and sunset of the Sun and clearly depicts the movement of the Sun in the orbit from the LEDs against the background of the landscape.
