Definitions

  • the invention relates to an analog display equipped with an electronic control Calendar with automatic update of the display, the combination of such Calendar with an analog clock and a method for manual time programming of the Control of such a calendar.
  • the invention relates to 2 solutions to the task of permanently displaying the day of the week and a permanent display of the day of the month of a calendar from only one electric drive to be driven.
  • FIG. 1 shows the block diagram of a variant of such a calendar.
  • the electronic assemblies Control (1), time standard (7), drive (s) (2), transmission (3), transmission status detection (4), time signal receiver (6) are part of the calendar work.
  • Electronic control blocks (1), Power supply (8), time standard (7), drive (s) (2), gear (3) and display (5) are in every variant of the calendar.
  • the effort for a radio wall calendar is not greater than the effort for a radio wall clock with a mechanical display device.
  • Identical microcontroller controls can be used for the radio wall calendar and the radio wall clock, which are only operated with different software.
  • the gear ratios of the gearbox differ somewhat (in the case of less favorable gear ratios for the calendar, the gearboxes can even be the same), but the same drives (stepper motors) can be used.
  • the clockwork and the calendar movement can be installed in housings with identical dimensions. This watch or calendar movement case can then be used in the same watch case. Only the dials of the clock and the calendar differ. A manufacturer of radio clocks can therefore also produce a radio calendar with minimal additional effort.
  • the electronic control of the calendar is advantageously implemented as a microcontroller control.
  • the Clock generator of the microcontroller is stabilized by a quartz.
  • the time and gear register are part of the working memory of the microcontroller.
  • the calendar In conjunction with an external clock showing the time of day, the calendar should be able to display the complete time information of a year in an analog form from the month down to the second. Since conventional clocks which display the time of day analogue only have an hour scale with a 12-hour dial and therefore do not allow the day to be differentiated, a preferred embodiment of the calendar is intended to make this distinction possible. This is achieved without an additional pointer in that each weekday segment of the weekday scale is further divided in time. In conjunction with a multi-step walk through the weekday segment through the weekday pointer, the controller drives the weekday pointer so that daily segments are displayed for each weekday. Furthermore, there is a sensible subdivision of the rather large weekday segments.
  • a day section on the weekday scale can be separated from the preceding and the following day section by boundary lines and labeled with the time of the day section (e.g. 6-12 a.m.). Especially if a day is divided into many day segments (e.g. 12 day segments of 2 hours) and the step size of the day of the week pointer is small, only individual times in a day segment of the week can be marked (see Figure 2). The reader of the calendar must be aware, however, that the time of a day section is not shown exactly, but the time shown. If, for example, the controller can set the day of the week pointer to the positions 0:00, 2:00 ... 10:00 p.m.
  • a day segment of 2 hours is displayed in each of these positions, e.g. in the position 2:00 the day section from 2:00 to 3:59:59.
  • the weekday hand on the associated shaft in such a way that it comes to a standstill during the 12-step movement of a weekday segment in the positions 1:00, 3:00 ... 23:00.
  • the control would then have to drive the day of the week so that, for example, in the 3 o'clock position, it shows the day section from 2:00 am to 3:59:59 pm.
  • the ( Figure 2) shows the display (5) of a calendar, consisting of a weekday pointer (10), the a weekday scale (11), a month hand (12), the one with a day scale (13), and a Month hand (14), which interacts with a monthly scale (15), with the 3 scales on a dial (9) are arranged.
  • Each segment of the weekday scale (11) is with the weekday and three Times of the day (6, 12 and 6 p.m.) labeled.
  • the boundary between the day of the week marks indirectly the time 0 or midnight.
  • Another object of the invention is therefore to provide a gear connection between the day of the week and day of the month, in particular for a calendar according to claim 1, so that these displays can be driven by only one electric drive. This task was solved several times. According to the invention, this object is achieved once with the third claim.

  • the day of the week pointer (18) is on a Monday, for example, and the day of the month pointer (22) is on a 1st day of the month, it would not be sufficient if the controller only moved the drive forward one step. Then the day of the week hand (18) would change to a Tuesday, but the day of the month hand (22) would still be on the 1st day of the month.
  • the control must let the drive advance 8 steps in order to set the day of the week pointer (18) to a Tuesday and the day of the month pointer (22) to the 2nd day of the month (see Figure 4a).
  • the controller is also able to do this, because it calculates the target position of the pointers taking into account the time in the time registers, the gear ratio and the assignment of the gear positions to the parameter values shown on the scales. If one or more days of the month have to be overrun if a month changes with less than 31 days, the control drives the drive a correspondingly larger number of steps.

  • the day of the month pointer (22) is set to the 30th day of the month

  • the microcontroller requires a supply voltage in the range from 2.5 to 5.5 V, it can be operated with clock frequencies from 32 kHz to 20 MHz and has 11 I / O pins (direction programmable) and 1 input pin (Pin4 - RB3).
  • An external crystal can be connected to pins 2 and 3, otherwise an internal RC oscillator is used for clock generation.
  • the microcontroller includes an 8-bit timer that can count the clock pulses divided by a programmable divider, as well as an internal power-on-reset circuit.
  • the microcontroller is operated in the circuit with an operating voltage of 3V and a quartz-stabilized clock frequency of 32768 Hz, which serves as the time standard, and even in this configuration consumes a current of approximately 15 microamps (uA).
  • the outputs can deliver both low and high levels of at least 5mA (at an operating voltage of 2.5V). Since the stepper motors are designed for a voltage of 1.5V, a series resistor of 240 ohms is connected in front of each stepper motor. A fully assembled module is used as the DCF77 receiver.
  • the circuit of this module is not shown here, only the interface was drawn, via which the receiver is connected to the controller.
  • the operating voltage of the DCF77 receiver must not exceed 2V. It is switched on by the RB0 output of the microcontroller and stabilized to slightly below 2V via the green LED (D3).
  • the program-controlled connection of the supply voltage of the DCF77 receiver fixes the low-active enable input (DCFOn /) to ground.
  • the second pulses of the DCF77 signal are made available via the output DCF77 of the receiver, amplified via the transistor Q2 and reach the input RB3 of the microcontroller.
  • the program of the microcontroller ensures that when the DCF77 receiver is switched on, the second pulses are indicated by the red led (D2).
  • the state of the jumper JP1 and the state of the light barrier of the calendar can be queried at the input RB3 of the microcontroller via the infrared transistor Q1.
  • the controller may only activate one of the 3 elements. For example, if the control has switched on the operating voltage of the DCF77 receiver via output RB0 in order to query the seconds pulses at output DCF77, the infrared LED D1 must be switched off and the jumper JP1 must not be set.
  • the jumper JP1 is used to place the pointer, whereby the gear of the calendar is brought into a clear starting position.
  • the clock frequency of the microcontroller of 32768 Hz serves as the time standard.
  • a programmable divider and the 8-bit counter / timer are initialized so that the frequency is divided from 32768 Hz by 128 to 256 Hz and then fed to the 8-bit hardware counter. This counter thus overflows every second. Since the PIC 16C505 microcontroller has no interrupts, the software must ensure that any overflow of the 8-bit hardware counter is recognized. Based on this overflow that occurs every second, the software counts the seconds, minutes, hours, days of the week, days of the month, months and the distance from the leap year in further registers in the data memory. The program takes into account the different number of days of the month depending on the month and year with 365 days or the leap year with 366 days.
  • the software can determine the length of an event with an accuracy of 4ms. For example, the software can switch on the magnetic coils of the stepper motors for a defined time or measure the pulse length of the second pulses of a DCF77 time telegram. Before the time is displayed, the software must determine the gear unit status and read in a DCF77 time telegram.
  • the gearbox level detection is carried out first. For this purpose, the position of the day of the week wheel is first determined, for which step motor SM1 (42) is switched one step further, then the infrared LED D1 is switched on and the state of the light barrier is queried by querying the phototransistor Q1. This continues until it is possible to conclusively determine the status of the weekday wheel. If after a certain number of steps of the stepper motor SM1 the light barrier is not transparent, the day or month wheel interrupts the light barrier. Then the stepper motor SM2 is advanced a few steps before the process is repeated with the stepper motor SM1.
  • the stepper motor SM2 (44) is moved for this purpose.
  • 3 positions can be recognized based on the coding of the monthly wheel.
  • the gearbox will be moved to a clear position for setting the pointer (e.g. January 1, Monday, midnight).
  • the position of each pointer is saved by the software in gearbox status registers. These registers are updated with every step of a stepper motor. Now the registers that count the time are synchronized with the DCF77 time telegram.
  • the DCF77 transmitter transmits a carrier frequency of 77.5 kHz, which is reduced to 25% of its amplitude every second for a period of 100 ms (low bit) or 200 ms (high bit). These reductions are also referred to as second marks and encode the time information.
  • the time stamp of the 59th second is missing and indicates the end of a minute. These second marks are present at the DCF77 output of the receiver as a high level, otherwise this output is at a low level.
  • the control now switches on the DCF77 receiver, waits for the missing time stamp of the 59th second, then starts the evaluation, measuring the length of the second marks, assigning them high or low levels and then saving them. If all seconds marks up to the 59th second could be recognized, if there were no errors in the length measurement and no parity errors, then the conversion into the binary number system takes place. If the time is valid, the time registers are synchronized with the imported time telegram. If an error occurred, a new time telegram is read. After reading in a time telegram, the time registers are continuously updated by the control. The target position of the pointers is calculated taking into account the time register, the gear ratio and the assignment of the gear positions to the parameter values shown on the scales.
  • the stepper motors and thus also the pointers are then advanced until the target position of the pointers matches the actual position stored in the transmission status registers. Since the calendar and the clock now run with quartz accuracy, the DCF77 receiver is switched on for synchronization once a day at 3.00.45 and tries to read in a new time telegram. If a time telegram cannot be read due to poor reception, the DCF77 receiver is switched off again at 3.08.15. Time telegrams that were read incorrectly are ignored.
  • the time-counting registers and, if necessary, the weekday pointer are corrected.
  • the green LED D3 indicates that the DCF77 receiver is switched on, the red Led D2 shows the seconds markers. In the event of poor reception, a change in the calendar can attempt to find a better reception position.
  • the time and gear status registers are part of the working memory of the microcontroller.
  • the power consumption of this variant of the calendar is to be examined.
  • the current consumed during commissioning for gearbox level detection is not taken into account.
  • the current through the solenoid of each stepper motor should be 5mA and the solenoid should be switched on for 50ms per step.
  • the DCF77 receiver is switched on for an average of 3 minutes every day.
  • the red LED for displaying the seconds mark requires a current of 2mA, which however only flows for around 15% of the switch-on time.
  • This also includes 2 stepper motors and 2 gears, some of the gears of the gears are coded and illuminated by a light barrier for gearbox level detection.
  • the former second hand which rotates once with 60 steps of a stepper motor, is now used to display the day of the week and the former minute and hour hand, which rotates once with 240 or 12 * 240 steps of the second stepper motor, is now used for the day of the month or month.
  • the original microcontroller circuit of this radio clock for the calendar, only special software being used for a calendar. In this case, such a radio calendar would only differ from a radio clock by the use of a special software variant and a different dial.
  • the gear ratios of this radio clock are not optimal for a calendar, so that the gear ratios of the gear should also be changed. A manufacturer of such radio clocks can thus also produce a radio calendar with minimal additional effort.
  • Claim 9 describes a calendar-clock combination. In order to simplify commissioning, both the calendar and the clock have a gearbox level detection. The features listed in the 9th claim ensure that the clock and the calendar run synchronously.
  • Figure 17 shows the block diagram of a variant of such a calendar-clock combination, which is equipped with a time signal receiver.
  • Figure 18a shows the front of a housing (66) with the dials of the clock and the calendar, in which such a calendar-clock combination was installed.
  • Figure 18b shows the back of this housing (66) with a built-in calendar movement (61) and a built-in clockwork (67).
  • the calendar mechanism (61) contains the power supply (battery), the control (1), a time signal receiver (6), as well as the drive (s) (2), the gearbox (s) (3) and the gearbox status detection (4) of the calendar.
  • the clockwork includes the drive (s) (62), the gearbox (s) (63) and the gearbox position detection (65) of the watch.
  • the drive (s) (62) and the transmission status detection (65) of the watch are connected to the control (1) built into the calendar mechanism housing via a plug-in connecting cable (68). Due to the spatial separation of the clock and calendar mechanism, which are only connected via a cable, and the use of a dial for the clock and the calendar, large, easy-to-read displays are possible for both the clock and the calendar.
  • the control of the calendar can be synchronized with the current time by receiving a time signal, eg from the DCF77 transmitter, or by manual programming.
  • a time signal eg from the DCF77 transmitter
  • manual programming only one method is surely useful in which the parameter values to be programmed are visualized with a pointer of the calendar. Anything else would involve expensive additional hardware.
  • DE 3890910 T1 describes a method for programming the date for a clock with a minute and hour display, and a device for displaying the date (not shown in more detail). With a spindle which can be brought into 3 positions by pulling it out or pushing it in, the parameters to be programmed are selected as day of the month, month or year.
  • the value of the selected parameter can be changed, whereby the value is visualized by a pointer of the clock.
  • the pointer only moves to as many positions in one revolution as the parameter to be programmed includes values. For example, January is displayed when programming the month, with the second hand at position 5, February through position 10 and December through position 60. All intermediate positions are quickly overrun. The disadvantage of this method is that it cannot be read directly what has been set. You have to know that for example January corresponds to position 5 of the second hand. A spindle with 3 contacts and a pulse generator is also required. The setting of the time of day is not mentioned, presumably it is done in a conventional way, by turning the spindle minute and hour hands.
  • the task of manual programming of a calendar according to claim 1 is solved with the 10th claim.
  • the calendar control is programmed manually using a button connected to the control and is visualized by the day of the week (10) of the calendar.
  • the means for manual time programming listed as a feature in claim 1 thus consist of the button and the day of the week (10).
  • the control program communicates with the means for manual time programming and processes the procedural steps of the 10th claim.
  • the day of the month pointer can also be used to visualize parameter values, eg to visualize the days of the month.
  • the calendar is in programming mode. Now the parameters month, day of the month and day of the week are programmed with the time of day.
  • the parameter values are visualized by the day of the week pointer (10) running in succession to every possible value of a parameter and remaining there for about 1 second.
  • the weekday pointer (10) points to each month on the monthly scale (15, see FIG. 19b), the days of the month to every month on the monthly day scale (13, see FIG. 19c) and the days of the week with time of day to each Day of the week segment and each division of the time of day within this day of the week segment on the weekday scale (11, see FIG. 19d).
  • the next time will start with the first value (for example, after the 31st day of the month, the 1st day of the month will be started). This happens as long as the operator does not press the button. However, if the key is pressed, the currently set value is saved by the control in one of the time registers and the next parameter is programmed in the same way. After programming the last parameter, the day of the week hand (10) preferably still moves to a basic position (Monday, midnight). When the button is pressed again, the control starts counting the time and sets the pointers to the programmed time in high speed. This concludes the programming of the control. It is also conceivable that the year is also programmed to take leap years into account.
  • a leap year is visualized by pointing the weekday pointer (10) to the limit between Sunday and Monday of the weekday scale (11), the first, second or third year after a leap year by pointing to a position of the weekday scale (11) that is 90 °, 180 ° or 270 ° from this position (see Figure 19a).
  • the disadvantage is that no scale on the dial (9) of the calendar contains the years, so that a direct display of the values is not possible.
  • the manual programming of the control is to be explained using an example, whereby the time Monday, September 5, 1.30 a.m. is programmed in a leap year.
  • a calendar with a division of each weekday into 12 sections of 2 hours each is used. After the button has been pressed for at least 2 seconds, the calendar is in programming mode.
  • the leap year is shown by pointing the weekday hand (10) to the Monday position at 0 o'clock on the weekday scale (11) and then the first, second and third year after a leap year by pointing to a position that is 90 °, 180 ° or 270 ° is located from the position of the leap year, visualized, the weekday pointer (10) each running quickly to one of these positions and remaining there for one second (see FIG. 19a).
  • the weekday hand (10) repeats this cycle again and again.
  • the control saves the leap year in one of the time registers and now visualizes the months by the day of the week pointer (10) running quickly to a month segment of the month scale (15), remaining there for a second and continuing this process with the next month segment as long as the key is not is operated (see Figure 19b).
  • the controller saves the month of September in one of the time registers.
  • the day of the week hand (10) gradually starts the days of the week and their time on the day of the week scale (11), starting on Monday at midnight (see Figure 19d). Since one step of the drive advances the weekday hand (10) by 2 hours each, the time Monday, 1.30 a.m. cannot be shown exactly.
  • the operator could now press the button on the weekday scale (11) in the first position (Monday 0:00 a.m.) or in the second position (Monday 2:00 a.m.). In the first case, the calendar would run for 90 minutes, in the second case 30 minutes.
  • a method for manual time programming is to be presented for a calendar-clock combination according to claim 9.
  • a method analogous to the method for manual programming of the control with the calendar parameters according to claim 10 is conceivable for programming the time.
  • the programming of the control with the calendar parameters is carried out as in the method according to claim 10, but it is sufficient to program only the half of the day when programming the times of a day of the week, the day of the week then only visualizing the times of the day on the mornings and the mornings Afternoon is set.
  • the exact time of a half day is communicated to the control system by programming with the time.
  • Method step 10.6 is also omitted, since the time must first be programmed before the time counting begins and the programmed time is started by the pointers.
  • the hour and minute parameters of the clock are programmed one after the other.
  • the parameter values are visualized by the second hand, or if the clock does not have a second hand, the minute hand runs in succession to every possible value of a parameter and remains there for about 1 second.
  • the second hand or minute hand points to the hour successively to every hour (see FIG. 20a) and the minutes to each minute in succession (see FIG. 20b). This happens as long as the operator does not press the button connected to the control. However, if the button is pressed, the currently set value is saved by the control and the next parameter is programmed in the same way. If the second hand is used for visualization, it preferably still runs to the 0th second.
  • the method presented for programming the control of a calendar-clock combination with the time is also suitable for manual programming of the control of a radio clock if it cannot receive the time signal.
