Definitions

  • the present invention relates to a method for operating an information display device according to the preamble of claim 1, a receiving device according to claim 9 and devices for carrying out the method according to claim 10 or 11.
  • Alarm clocks designed as radio clocks are known, in which a user can specify an adjustable but then fixed time, at which the alarm clock then delivers an alarm signal.
  • Experience has shown, however, that conditions occur repeatedly in winter, which would cause the user to set the alarm clock to an earlier alarm time if he could foresee these conditions.
  • a risk of black ice preferably occurs at night or in the early morning, a user often cannot know whether he should set his usual wake-up time or rather an earlier wake-up time in order to be able to keep his appointments even in difficult road conditions.
  • the user can be warned of a critical situation on the street.
  • adverse traffic conditions can be taken into account.
  • the forwarding of the wake-up signal can at least partially compensate for the loss of time due to a possible traffic jam. Since some users do not look at the alarm clock when the alarm signal sounds, since they know the time (corresponds to the moment of the set alarm time), a variation of the alarm signal at that moment proves to be favorable. If the wake-up signal is brought forward, the changed sound of the wake-up signal immediately draws the user's attention to the fact that it is earlier than the originally set wake-up time. Likewise, regardless of whether the wake-up signal has been brought forward, the user immediately receives an indication of the potentially critical road situation due to the changed sound of the wake-up signal.
  • a method is already known in which a precise atomic clock of a receiving / transmitting station in Mainflingen sends a time in the form of a radio signal with a frequency of 77.5 kHz.
  • This signal is called the DCF77 signal.
  • This DCF77 signal is received by the Physikalisch-Technische Bundesweg in Braunschweig (Federal Republic of Germany). Taking into account the transmission time, this received time is compared with the time of a high-precision atomic clock. If deviations are found, appropriate correction signals are transmitted to the receiving / transmitting station in Mainflingen, near Frankfurt am Main, by means of a wired transmission.
  • the precise atomic clock of the receiving / transmitting station in Mainflingen is corrected accordingly in accordance with the incoming wired correction signals.
  • the DCF77 signals of the receiving / transmitting station in Mainflingen can then be used by so-called radio clocks, e.g. Wristwatches, wall clocks or table clocks such as Alarm clocks are received. It is now common practice to design such radio-controlled clocks to be battery-operated. In order to save energy and not have the receiver in constant operation with these radio clocks, these radio clocks are designed as so-called autonomous radio clocks.
  • These autonomous radio clocks have a time-keeping device by means of which the current time is continuously determined, for example with a quartz clockwork as in a conventional quartz clock.
  • the time signal reception only takes place once a day, for example.
  • the time determined continuously by the time-keeping device is updated, i.e. corrected if necessary. This possibly corrected time is then continued by the time-keeping device.
  • the time is determined from the received time signal by decoding the received radio signal. The time is shown by the autonomous radio clock.
  • a receiving / transmitting station is to receive time signals which are transmitted wirelessly, for example from the receiving / transmitting station in Mainflingen or other corresponding transmitters in the respective states. It is also possible to receive the data of the so-called GPS (Global Positioning System) and to derive a time signal from it.
  • GPS Global Positioning System
  • the receiving / transmitting station therefore receives wirelessly transmitted time signals according to the invention. Furthermore, the received time signals are then converted and forwarded to receiving devices, for example alarm clocks.
  • sensor signals are fed to the receiving / transmitting station, which are also sent by the receiving / transmitting station after they have been processed, if necessary.
  • the receiving device can receive, for example, meteorological data and display it when the sensors have meteorological data such as temperature, air pressure, air humidity or the like. measure up.
  • meteorological data such as temperature, air pressure, air humidity or the like. measure up.
  • at least the sensors can then be attached outside the apartment or house.
  • the receiving / transmitting station itself only has to receive the time signals at certain time intervals. It is then possible, for example, to transmit the data from the receiving / transmitting station to the receiving devices at certain predetermined time intervals, for example at intervals of one or more hours.
  • the receiving / transmitting station can determine the time intervals automatically on the basis of the time determined in its time-keeping device. Furthermore, it is advantageously possible to equip the time-keeping device with a more precise time-keeping device than the receiving devices.
  • the time keeping devices in the receiving devices are then updated during the data transmission from the receiving / transmitting station to the receiving device to the continuously determined time of the time keeping device in the receiving transmitting station.
  • the time-keeping device in the receiving / transmitting station advantageously makes it possible to save energy by receiving the time signal from the receiving / transmitting station, for example, only once a day.
  • an identification must first be sent so that the receiving devices can recognize whether the telegram was sent by the receiving / transmitting station assigned to them.
  • the content of the telegram can then at least partially consist of the current time and / or sensory data. If the time-keeping device continues the current time with a smaller division than the minute, it is possible to make the start of a telegram correspondingly more flexible.
  • the start of a (pure time) telegram is indicated by the 00 second mark (ie a mark that represents a full minute) being transmitted. If the time is now continued in seconds or, for example, in tenths of a second intervals, it is possible to send a telegram at any time according to the temporal resolution of the time-keeping device. The time transmitted in the telegram is then the current time when the telegram was sent.
  • the frequency range according to claim 4 has different criteria such as the size and the transmission quality of the antennas required proved to be advantageous.
  • the method according to claim 5 advantageously shows that the reception quality, ie the reception security, of the time signal received by the receiving / transmitting station increases. Error-free reception of a time signal may then still be possible even under difficult reception conditions.
  • the receiving / transmitting station with signals from sensors that detect quantities that can be measured, in particular, outside of rooms. Such quantities can be, for example, meteorological data such as the outside temperature, the UV radiation or the like. It is possible to record further parameters such as air humidity, air pressure, ozone content, radioactivity and, if necessary, to derive further parameters.
  • the UTC time from the GPS system or a time signal from the GLONASS systems are received and a local time is determined accordingly, which is difficult or impossible at all within closed rooms.
  • the time zone can be entered, for example, as well as the change from summer to winter time.
  • the receiving device can display the time inside the rooms with good reception security with reasonable hardware expenditure, as well as meteorological data that can only be measured outside the room.
  • antennas of a comparatively small size can be used in the frequency range for the transmission from the receiving / transmitting station to the receiving device. This results in improved possibilities for the external design, in particular of an autonomous radio-controlled wristwatch, since the housing of the wristwatch also only has to have a smaller size because of the smaller size of the antenna. It is conceivable that only a part of the further data coming from the sensors is displayed by the receiving device designed as a wristwatch.
  • a time signal for example the DCF77 signal
  • This signal is converted accordingly into a telegram which contains the respective time information and which is transmitted in the frequency range from approximately 30 MHz to 2.5 GHz, in particular 433 MHz, by the receiving / transmitting station to at least one receiving device designed as a wristwatch. It is conceivable to design the receiving / transmitting station as a table or wall clock, in particular as an alarm clock.
  • the current time continued in the receiving / transmitting station is corrected by means of the time signal received by the receiving / transmitting station.
  • a time telegram is sent from the receiving / transmitting station at cyclical intervals in the corresponding frequency range. If the wristwatch is then sufficiently close to the receiving / transmitting station, its continued current time is also corrected.
  • the threshold values that the user can specify can advantageously be a wake-up time if the receiving device is designed, for example, as an alarm clock. In this case, a wake-up signal is issued when the set wake-up time is reached. Threshold values can also be specified for additional data. If, for example, a threshold value for the outside temperature is specified, the corresponding signal can be output when the measured outside temperature falls below the threshold value. Accordingly, in the case of a UV sensor or an ozone sensor, the signal can be output when the measured UV radiation or the measured ozone concentration exceeds the respectively predetermined threshold value.
  • a fixed configuration results in a cost-effective construction of the device combination with regard to the sensors used.
  • the sensor signals are then evaluated in a controller in the receiving / transmitting station or in the receiving device.
  • the device according to claim 12 it is advantageous that flexibility with regard to the sensors used can be achieved.
  • the measured variable is to be recorded with the sensor which is to be connected to the receiving / transmitting station at a specific port.
  • the measured variable itself air pressure, temperature, humidity, ...) is fixed, as well as the physical unit in which the respective measured variable is displayed.
  • Only sensor-specific quantities, such as the offset voltage, are then stored in the data storage unit.
  • These sensor-specific variables then include, for example, in the case of a sensor whose output voltage has a linear behavior in relation to the measured variable, the voltage range of the sensor and the proportionality factor with which the output voltage of the sensor is to be converted into the value of the physical unit of the corresponding measured variable .
  • a table can be stored in the data storage unit, from which the value of the physical unit of the respective measured variable can be derived in accordance with the respective output voltage of the sensor - possibly by interpolation between stored values.
  • a device according to claim 12 to achieve greater flexibility by being able to freely select which measured variables are fed to the individual ports of the receiving / transmitting station via sensor signals. Then, in addition to the sensor-specific variables already mentioned, the data storage unit - which can be read out for the receiving / transmitting station - also stores the measured variable (air pressure, temperature, air humidity, ...) and information about which physical Unit this measured variable is to be displayed. Attaching the data storage unit to the receiving / transmitting station has the advantage in particular in the case of a plurality of receiving devices that only one data storage device must be present for each sensor.
  • the amount of information to be transmitted wirelessly is reduced.
  • At least the voltage values of the exchangeable sensors, to which data storage devices are assigned are forwarded to the receiving devices without further conversions.
  • the corresponding values of the measured variable are then determined in the receiving device from the respective voltage values, as has already been described in connection with the above claims for the determination of the values of the measured variables in the receiving / transmitting station.
  • measured variables can be detected that can only be measured at the location of the receiving device, such as the room temperature. This applies if the receiving / transmitting station is positioned outside the apartment. Furthermore, it is possible to reduce the amount of information to be transmitted wirelessly if it concerns measured variables which have the same value at the location of the receiving device as at the location of the receiving / transmitting station, such as, for example, the air pressure.
  • the device according to claim 14 offers a particularly inexpensive embodiment.
  • the device according to claim 16 it is advantageous that flexibility with regard to the further sensors used can be achieved.
  • the measured variable is to be recorded with the further sensor which is to be connected to the receiving device at a specific port. This means that the measured variable itself (air pressure, temperature, humidity, ...) is fixed, as well as the physical unit in which the respective measured variable is displayed. Then only specific sizes of the further sensor, such as e.g. the offset voltage is saved.
  • These specific variables of the further sensor then include, for example, in the case of a further sensor whose output voltage has a linear behavior in relation to the measured variable, the voltage range of the further sensor and the proportionality factor with which the output voltage of the further sensor is converted into the value of the physical unit of the the corresponding measured variable is to be converted.
  • a table can be stored in the data storage unit, for example, from which the value of the physical unit of the respective measured variable can be derived in accordance with the respective output voltage of the further sensor - possibly by interpolation between stored values.
  • the data storage unit - which can be read out by the receiving device - also stores the measured variable (air pressure, temperature, air humidity, ...) and information about the physical unit in which it is stored Measured variable should be displayed.
  • the time and, if appropriate, the sensor signals on the receiving / transmitting station. This makes it easier to find the source of the error, even during commissioning, if the receiving device displays incorrect values. If, in this situation, the receiving / transmitting tone shows the correct values, the error is due to the transmission or the receiving device.
  • the receiving-transmitting station can have a time-keeping device internally, so that the reception of the time signal 10 only has to take place at certain times.
  • the receiving / transmitting station 9 then still has the current time. For example, the time signal is received once a day, advantageously at 2:00 a.m. This has an advantageous effect in a battery-operated receiving / transmitting station, since it can save energy compared to a permanently activated receiver.
  • This time signal can be, for example, the DCF77 signal or a time signal that is derived from the GPS system.
  • a plurality of sensors 1, 2 are permanently connected to the receiving / transmitting station.
  • the receiving / transmitting station in the exemplary embodiment in FIG. 1 a controller.
  • the data required for evaluating sensors 1 and 2 are permanently stored. If it is clear which sensors are to be used, the device is inexpensively constructed.
  • Fig. 1 can also be seen that sensors 3, 4, 5 and 6 are present, which are connected to the receiving / transmitting station interchangeably. As a result, a certain flexibility can be achieved with regard to these sensors. If, for example, one of these sensors is defective, this sensor can be replaced individually.
  • the data required for evaluating sensors 3 and 4 are also permanently stored. These sensors are interchangeable, as already described above. If the parameters required for evaluation by sensors from different manufacturers match, then sensors from different manufacturers can also be used.
  • the sensors 5 and 6 are also interchangeably connected to the receiving / transmitting station. These sensors 5 and 6 are each assigned data storage units 7 and 8, from which data belonging to sensors 5 and 6 can be read out by the receiving / transmitting station 9.
  • the following data belonging to the sensor 5 can be stored in the data storage unit 7.
  • a table can be stored in the data storage unit, for example, in which certain voltage values are assigned specific values of the measured variable.
  • the associated value of the measured variable can then be read out from this table for a specific voltage value. For example, this value can be obtained by extrapolation if the measured voltage value is between two
  • the designation of the measured variable of the sensor 5 and the designation of the physical unit are permanently stored.
  • additional information can be stored in the data storage unit 8 for the sensor 6, as shown in connection with the sensor 5.
  • the connection of the sensor 6 can be designed particularly advantageously with great flexibility if, in addition to the sensor-specific data mentioned, with which the measured voltage value is converted into the value of the measured variable, a name of the measured variable - such as the string "OZON:" - and the name of the physical unit of the value of the measured variable are stored as a string of letters.
  • the system consisting of the receiving / transmitting station 9 and the receiving device 12 no determination has yet to be made as to which measured variable is to be detected with a sensor which is connected to the connection of the sensor 6.
  • the designation of the measured variable and the associated physical unit are then likewise sent from the receiving / transmitting station 9 to the receiving device 12 and displayed there on a display 13.
  • Fig. 2 shows a further device consisting of a receiving / transmitting station and a receiving device.
  • the same components as in FIG. 1 have the same reference numbers in the device according to the exemplary embodiment in FIG. 2 and therefore do not have to be explained separately.
  • the receiving device in the exemplary embodiment in FIG. 2 has integrated sensors 14 and 15, with which measured variables can also be detected, evaluated and displayed on the display 13. The evaluation of these sensor signals then takes place in the receiving device 12 and otherwise corresponds to the evaluation of the sensor signals 1 and 2, which has already been explained in connection with FIG. 1.
  • measured variables can be displayed that can only be measured at the location of the receiving device and not at the location of the receiving / transmitting station. This is the case, for example, if the receiving / transmitting station is installed outside the house and the receiving device inside the apartment. One of the sensors 14, 15, 16, 17 can then detect the room temperature. In this case, this measured variable would not be detectable by the receiving / transmitting station.
  • Another measured variable that has the same value inside and outside the house is, for example, the air pressure.
  • the amount of data to be transmitted wirelessly from the receiving / transmitting station to the receiving device can be reduced. It is also possible for several receiving devices to receive the data sent by the receiving / transmitting station. When attaching the sensors to the receiving devices, there is then a certain additional outlay because the respective sensor must be attached to each receiving device on which the respective measured variable is to be displayed. A reduction in the amount of data to be transmitted then goes hand in hand with increasing hardware expenditure, since more sensors are required.
  • sensors 16 and 17 are provided, which can be exchangeably connected to the receiving device 12.
  • the signal from the sensor 16 can, for example, be evaluated in accordance with the evaluation of the signals from the sensors 3 and 4, with the difference that the evaluation of the signal from the sensor 16 takes place in the receiving device.

  • the sensors can be connected in any combination with the receiving / transmitting station 9 and the receiving device 12 in a fixed or interchangeable manner, all or even only individual ones of the interchangeably connected sensors can in turn be assigned data storage devices which are connected to the receiving / transmitting station 9 or the receiving device 12 are connected. Likewise, several receiving devices can be assigned to one receiving / transmitting station.
  • threshold values can also be specified by the user. For this purpose, it is necessary to provide an input unit on the receiving / transmitting station 9 and / or on the receiving device 12, for example a numeric keypad, which may be expanded with an input option for letters.
  • the threshold values can be related to the corresponding sensors 5; 6; 17, for example, also in the respectively assigned data storage devices 7; 8, 19; 18 filed.

  • monitoring is carried out with regard to the threshold value in the receiving / transmitting station, an identifier for the warning is transmitted with the other data.

  • the receiving / transmitting station 301 designed as a table clock is designed such that it sends a processed time signal 303 to a receiving device 302, which is designed as an autonomous radio wristwatch. Because of the advantageous frequencies for the transmission of this time signal 303, the antenna of the autonomous radio wristwatch has a significantly smaller size. This makes it much easier to achieve an appealing design of a radio wristwatch.
  • the receiving / transmitting station 301 designed as a watch can be designed particularly advantageously as a travel alarm clock. Their design should be chosen so that it is not only used as a travel alarm clock but also as an alarm clock in daily operation.
