Definitions
- the invention relates to a chronometer for measuring and displaying geophysical data by means of a sensor, transmitter, a sequence control and a display for displaying, in particular, the phases of the moon.
- the apparent shape of the moon in the sky - its phase - depends on its position on its orbit around the earth. If it is between the sun and the earth, so that the sunlit hemisphere cannot be seen from the earth, it is a new moon. A sickle can be seen shortly afterwards. When the moon moves on its orbit, the sickle grows, the moon increases and finally half of the side facing the earth is illuminated: the moon is in the first quarter; he has walked a quarter of his way. It continues to increase and is finally full. As he continues on his path, he begins to lose weight, reaches the last quarter and becomes a sickle again. The cycle starts again with the next new moon.
- the moon needs 27.32166 days for a complete orbit around the earth, measured against the background of the fixed stars. This period is called the sidereal month. Since the earth is around itself Sun moves, the interval between two new moons is slightly longer than a sidereal month; it is called the synodic month and lasts 29.53059 days. This period is also called the lunar month or lunation.
- the present invention has for its object to provide a chronometer for displaying the moon phases, which is simple to use and has a high accuracy. According to the invention, this object is achieved in that the moon phases are calculated by means of a digital sequence control and are shown on the display by means of pictogram symbols.
- the course of the moon phases is preferably divided into eight time ranges, which are shown in the display by eight different pictogram symbols.
- time ranges for displaying the different pictogram symbols are all of the same or different lengths. In the case of time periods of different lengths, these can preferably be all day and alternate by one day.
- the sequence control for calculating the moon phases and their representations as pictogram symbols in the display consists of a time base in the form of a quartz, frequency dividers, counters, an input unit, a read-write memory (RAM), a read-only memory (ROM) ) and an arithmetic-logic unit (ALU).
- a time base in the form of a quartz, frequency dividers, counters, an input unit, a read-write memory (RAM), a read-only memory (ROM) ) and an arithmetic-logic unit (ALU).
- the chronometer according to the invention has the essential advantage that the initial conditions or initial values are calculated automatically by entering the current date, and the current moon phase can thereby be represented precisely and very precisely.
- a synchronism is provided which drifts the moon phase representations away by comparing current data with data stored in the read-only memory (ROM) prevents what can alternatively or simultaneously happen by synchronizing the time base of the chronometer with radio receiver from a central radio transmitter.
- Fig. 4 the eight different pictogram symbols.
- FIG. 1 shows with reference number 1 the sequence control of the chronometer according to the invention for calculating the phases of the moon and their representation as pictogram symbols I (FIG. 4). These are shown in display 2.
- the main components of the sequence controller 1 include a time base in the form of the quartz 3, from frequency dividers 4, counters 5, the input unit 6, the random access memory (RAM) 7, the read-only memory (ROM) 8 and the arithmetic-logic unit (ALU) 9.
- the sequence of the moon phases is divided into eight time ranges by the hardware in the form of the sequence controller 1 in connection with its software, and the moon phases are shown on the display 2 by eight different pictogram symbols I.
- the eight time periods can all be of the same or different lengths.
- the time data of significant moon phases in particular new moon and / or full moon, are stored in the fixed value memory (ROM) 8.
- ROM fixed value memory
- the phases of the moon are shown by counting the moon's orbital time around the earth in a counter of sequence control 1 and by dividing it into eight time periods or eight phases, these phases being shown cyclically by the pictogram symbols I.
- the calculation and display of the moon phases after calculation of the initial values is the time base 3 of the sequence controller 1 via the significant moon phases stored in the fixed value memory (ROM) 8, in particular the new moon and / or full moon synchronizable.
- the time base 3 can alternatively or additionally be synchronized with exact data by a radio time base via the integrated radio receiver 10.
- the difference between the currently entered date and the date of the immediately preceding significant moon phase, in particular the new moon and / or full moon is formed from the date stored in the fixed value memory (ROM) 8.
- This difference value is then divided by 3.6875 and the calculated value is split into the integer value X and the fraction Y.
- the division by 3.6875 results from the synodic month with approx. 29.5 days and division by 8 phases.
- the integer value X represents the initial condition and thus the first displayed and assigned pictogram symbol I on the display 2.
- the fraction Y is multiplied by 10 and a 1 is added or incremented to this value every 8.85 h until the number thus formed has reached the value 10. If this is the case, a 1 is added to the integer X, whereby the sequence control 1 shows the next following moon phase in the display 2.
- the current date is February 28, 1997, 1 p.m.
- the chronometer is started by entering this date.
- the date of the immediately preceding significant moon phase, in particular the new moon is stored in the fixed value memory (ROM) 8 and is February 23, 1997, 7 p.m.
- the difference to be formed is 4 days and 18 hours or 4.75 days. This value is divided by 3.6875 and results in around 1.3.
- the fraction Y 0.3 is multiplied by 10, giving 3 and every 8.85 h a 1 is added to this value or incremented until the value 10 is reached.
- the value of 8.85 h is the tenth of 3.6875 days. If the value 10 is reached by incrementing 1 every 8.85 h, a 1 is added to the value X, which results in a 2 in the present example. Ie: Now the second pictogram symbol, a sickle, is shown in display 2.
- a 1 is added to the value X + 1 in a counter of the sequential control 1 every 3.6875 days, the counter being a "modulo-8 counter” and the display phase value (DV) thus formed represents the eight pictogram symbols I.
- a “modulo-8 counter” counts from 1 to 8 and then starts again at 1.
- FIG. 2 A flow diagram, which will be explained in detail for these moon phase representations of the same length, is shown in FIG. 2.
- the display time can vary between two successive moon phases, in particular alternate, preferably by one day, if the display time for the respective moon phase is to be in whole days.
- the flow chart of FIG. 3 which will be explained in detail later.
- a "modulo-59 counter” increments the sequence control 1 per day with 2 after calculating the initial conditions, which means that the eight moon phase pictogram symbols I can be shown on the display 2 for 4 or 3 successive numerical values and the eight moon phases over the connected numerical values or moon phase values (MPV) of the "modulo-59 counter” can be shown cyclically on the display 2.
- the type of counter modulo 59 results from the moon's orbital period of 29.5 days multiplied by 2, which gives whole numbers.
- the modulo-59 counter has counted to 59 and is incremented with 2, it starts again at 2 and counts in steps of two to 58, then it starts again at 1 and counts up to 59 and so on
- the calculation of the initial conditions for alternating moon phases using the modulo-59 counter according to the flowchart in FIG. 3 is the same as for moon phases of the same length according to the flowchart in FIG. 2.
- FIG. 2 For an explanation of the flow diagrams, reference is first made to FIG. 2. Using this diagram, eight “moon phases" of equal length are represented in the "steady state" by eight different pictogram symbols I on the display 2.
- the current date by year, month, day, hour, minute is entered via the input unit 6 of the sequence control 1.
- This value is compared with the date of the immediately preceding significant moon phase, especially the new moon, and the difference is formed. This difference usually results in days, hours and minutes.
- this difference is divided by 3.6875 and you get the number Z, which is composed of the whole number X and the fraction Y.
- X is split off and fed to the display 2 via a register, and by agreement one is assigned to this number Pictogram symbol I shown in display 2.
- the fraction y is multiplied by 10 and a 1 is added incrementally every 8.85 h until the value 10 is reached. Then the value X + 1 is formed and displayed on the register in display 2. Then, in a modulo-8 counter, a 1 becomes every 3.6875 days for the value X + 1 added and shown on the register in the display 2. The eight moon phases now cycle through the modulo-8 counter every 3.6875 days.
- the flow diagram of FIG. 3 with alternating moon phases can be seen from the flow diagram of FIG. 2.
- the calculation of the initial conditions is the same.
- X is formed as already described, Y is multiplied again by 10 and incremented by 1 to 10 every 8.85 h.
- X is shown on the register in display 2 as the corresponding pictogram symbol I.
- X + 1 is shown and in a counter to X + 1 every 3.6875 days 1 is added until the value 8 is reached and this value is shown in display 2 via the register.
- the initial conditions are met. Now increment in a modulo-59 counter per day with 2 and the values obtained in this way are divided into areas according to the flow chart of FIG. 3.
- the moon phase numbers (MPV) 2,4,6,8 or 1,3,5,7 are assigned to the first display value (DV), eg 1, via the register and shown as a corresponding pictogram symbol I on the display.
- the moon phase values (MPV) 10, 12, 14, 16 or 9, 11, 13, 15 are assigned to the second display value (DV) via the register, for example as 2 and shown as a corresponding pictogram symbol I in display 2.
- the moon phase values (MPV) 52,54,56,58 or 51,53,55,57,59 are formed and via the register as eighth value and according to the agreement as eighth pictogram symbol I in display 2 Brought ad. After that, all states recur cyclically.
- the pictogram symbols I are preferably shown in the display 2 in a 12-second cycle and in the first second a moon, in the second second two moons, in the third second three moons, in the fourth second four moons, in the fifth second five moons, six moons in the sixth second, seven moons in the seventh second, eight moons in the eighth second and from the ninth to the twelfth second the current phases of the moon are displayed.
- the chronometer according to the invention can display further geophysical data, in particular the temperature, the air humidity, the air pressure, the time and weather information on the display 2.
