Definitions

  • the invention relates to a radio-controlled clock, in particular a radio-controlled wristwatch, with a movement with a time pulse-driven stepping motor which drives a movement with clock hands rotating in front of a dial, a long-wave radio receiver for receiving time-determining data and non-time-dependent data, in particular weather data.
  • Such a radio clock is from the DE-PS 197 20 591 known.
  • This radio-controlled watch is capable of transmitting, for example, information encoded by the long-wave transmitter DCF 77 on the one hand over the second, minute, hour, day, day of the week, month and year, ie time-determining data, and on the other hand via current and forecast weather data, that is, non-time-consuming data. to receive and implement them to set the clock or to display the weather data.
  • the weather data are displayed by means of four LCD display areas, which are controlled on certain days to display different weather conditions, such as sunshine, cloudy sunshine, cloud cover and precipitation / thunderstorms. Additional LCD display areas are provided for displaying the temperature and the region to which the weather data relates.
  • the respective desired region can be adjusted by means of a manually operable knob.
  • a wireless wristwatch which has a conventional movement with rotating in front of the dial seconds, minutes and hour hand and in addition LCD display elements for displaying the weather data, represents a technically complex construction, which is also expensive to manufacture, and has a relatively large weight, which is basically undesirable in a wristwatch.
  • Another disadvantage of this wristwatch is its high energy consumption when displaying the weather data, which not only further increases the weight of the watch due to the large and expensive batteries required thereby, but also requires frequent battery replacement in comparison to other electronic watches.
  • a radio-controlled wristwatch which is designed to receive, for example, the long-wave transmitter DCF 77 in encoded form over the second, minute, hour, day, weekday, month and year, ie time-determining data.
  • the second, minute and hour are indicated by the clock hands, the day, week or month or year after the actuation of an electrical switching unit by the second hand, which is briefly set to the current day or the current day of the week.
  • this watch Since additional sensors are needed to display temperature, air pressure, and other physical data at the location where the wearer of the watch is located, this watch has basically the same disadvantages as the watch after DE-PS 197 20 591 : complex construction, expensive production, large weight and large volume and high energy consumption, which leads to frequent battery change.
  • the individual non-time-related data are each assigned a specific drive signal corresponding to a specific clock position, that means for continuously storing the current time are provided, and means which interrupt the display of the current time by actuating the manual switching means. control the stepping motor with the pointer mechanism into a pointer position corresponding to a display control signal, and then drive the stepper motor with the pointer mechanism to resume display of the advanced current time.
  • a specific drive signal with a specific clock position can be used in conjunction with various arranged on the dial symbols various non-time data - in weather data, for example, the forecasted weather (sunshine, clouds, rain, etc.), the forecast temperature and the forecast air pressure in one indicate a specific region of a forecast area simultaneously using the second, minute and hour hands.
  • Such a display corresponds, for example, to a "time" of 13:59:56 minutes and 40 seconds.
  • the possible simultaneity of the display of various weather data causes only a one-time adjustment of the clock for different data, which has a significant prolongation of the battery life compared to the above-mentioned known radio clocks. Due to the further measures - means for continuously saving the current time and mentioned control of the stepping motor - after the display of the weather data correction of the clock on the current time is not required.
  • the stepping motor is controlled by the clock mechanism with clock pulses high clock frequency in a pointer control position corresponding to the display control signal and then with clock pulses high clock frequency to resume the display of the advanced current time.
  • the stepper motor is applied with the pointer mechanism with second pulses, so that the second hand moves forward in 1 Hz cycle.
  • the stepper motor with Timing pulses in the 100-Hz clock or higher applied The higher the clock frequency is selected, the more weather data can be displayed, or, given a certain amount of weather data, the display duration of the weather data lengthened, which facilitates the handling of the clock, in particular its readability in the display of the weather data.
  • the stepping motor is controlled with the high frequency clock mechanism in a pointer position corresponding to the display control signal and applied to the clock pulses normal clock frequency upon reaching the advanced current time.
  • the stepper motor can not overshoot on resumption of the time display, as can happen in the embodiment described above, when it should continue to come from high clock frequency in normal clock frequency.
  • the display of the display control signal corresponding pointer position can also be done by the minute hand of the pointer movement according to a variant of the invention. This is particularly advantageous if the radio clock, for example, for reasons of design, should have no seconds display.
  • the weather data information radiated by the long-wave transmitter DCF 77 usually refers to different regions of a forecast area which may refer to different federal states of the Federal Republic of Germany and adjacent areas such as Luxembourg, Belgium, the Netherlands, Denmark, Tru, the Czech Republic and so on.
  • a forecast area which may refer to different federal states of the Federal Republic of Germany and adjacent areas such as Luxembourg, Belgium, the Netherlands, Denmark, Tru, the Czech Republic and so on.
  • the most realistic picture possible of the forecasted weather for his region for example Thuringia, means are provided for selecting and displaying certain regions from the transferred forecast area.
  • the display of a region of the prediction area may be by means of a liquid crystal display disposed on or in the dial of the watch, or by locating the regions along the minute scale of the dial.
  • the advantage of the first mentioned construction is that it is always visible to which region of the forecast area the weather forecast relates.
  • the disadvantage is their higher energy consumption and the additional use of a liquid crystal display, which leads to higher production costs.
  • the advantage of the latter embodiment is its simple construction, the disadvantage that always first the region is displayed and then only the weather information, which is more time consuming. Which of the two embodiments comes into play, so to decide from case to case.
  • this region will always be shown in the display; in a display by means of the hands of the clock, the display of the region can either be switched before the display of the weather data or, which is more advantageous for energy reasons and time savings, completely omitted, but the user generally knows which region is effectively connected, in particular if he stays mainly in this region.
  • the dial is provided in a preferred embodiment with graphic symbols for sunshine, sunshine with clouds, clouds and precipitation, which are highlighted with a clock of the movement. Since the weather data transmitted by the longwave transmitter can contain further subdivisions of the weather event - for example thunderstorms, snowfall, fog, etc. - corresponding symbols can also be provided on the dial, if desired, for these weather situations.
  • the graphical symbols for the weather and then a temperature scale along the minute scale of the dial are arranged thereon.
  • various values associated with this symbol such as air pressure or precipitation probability
  • this symbol may be arranged in an arc, such that when these values are indicated by a clock, this also points to the graphic symbol.
  • Properly displaying clock and weather data on a radio clock depends to a large extent on the strength of the received signal that the radio clock has at its place of use.
  • At transmitter-remote positions may already cover the wristwatch through a jacket sleeve and / or through a stay in a building constructed of reinforced concrete lead to the fact that the weather data (and also the time-determining data) can be received only fragmentarily. This can lead to misinformation.
  • means are provided which indicate the orderly or improper reception of the non-periodic data.
  • a plus sign is provided at the 12 o'clock position on the dial, which is highlighted by one of the clock hands at the beginning of the display of a weather forecast.
  • a minus sign in the 6 o'clock position on the dial may be provided to indicate an improper receipt, which is highlighted in the corresponding case by a pointer of the clock.
  • the radio wristwatch includes an electronic circuit comprising a longwave radio receiver 1 and a weather data generator 2 which converts the weather data from the received radio signal into display control signals, and a quartz oscillator 3 which can be synchronized with the time signal of the longwave radio receiver 1 in a known manner.
  • the quartz oscillator 3 supplies time pulses with a clock frequency of 1 Hz and with a high clock frequency, for example 100 Hz.
  • the 1 Hz clock is used for normal progression of the stepping motor 4 in the movement and thus the second hand 5, which rotate together with the hour hand 6 and the minute hand 7 in front of the dial 8 of the radio alarm, and to set the time register 9.
  • the time register 9 and the Time display registers 10 have separate h, min, and sec outputs which can be compared to each other by the comparator 11 for identity.
  • the weather data generator 2 generates a specific sec information corresponding to the decoded weather situation, which corresponds to the second hand position to be displayed on the dial 8 and thus to the weather symbol located there.
  • the applied to the comparator 11 sec-information can be switched by means of the AND gate 12 from the weather data generator 2 to the sec information of the comparator 11 .
  • the outputs of the AND gates 15 and 16 are unequal, causing the output 22 of the comparator to go to zero.
  • the 1 Hz clock signal is stopped via the AND gate 18 and released via the AND gate 19, the 100 Hz clock signal to drive the stepping motor 4 .
  • the drive of the stepping motor 4 to the 100 Hz clock signal, the accelerated running of the second hand 5 and the accelerated counting of the time indication register 10 take place until the comparator 11 supplies the identity signal (output signal 22 high) at the output of the comparator 11, and as a result whose switching to the 1 Hz clock takes place.
  • the second hand 4 has now reached its desired position and points to the current weather symbol.
  • the dial 8 of the radio-controlled watch is provided on an outer ring with hour and minute marks 26 and in 6 o'clock position with a liquid crystal display 27 for displaying the date, the region for the weather forecast to be displayed and the period of the weather forecast, namely, whether the forecast is for the day - as drawn - or for the night.
  • a pressure switch 29 for retrieving the desired weather data.
  • FIG. 1 shows the clock in its normal time-indicating state. It displays a time of 13:58:00 clock. After pressing the Pressure switch 29 moves the second hand 5 in a position in which it indicates a temperature of 22 ° C ( Fig. 2 ). Upon subsequent actuation of the pressure switch 29 , the second hand 5 moves to the symbol 30 "light clouds".
  • the indication of the temperature and weather forecast relates, as can be seen from the LC display, to the Berlin region and the course of the day on 30 June.
