Definitions

  • the invention relates to a radio-controlled watch according to the preamble of claim 1.
  • Radio controlled clocks belong to the state of the art.
  • This radio broadcast signal contains in coded form the information about minutes, hours, calendar days, weekday, calendar month, calendar year and is broadcast every minute.
  • a description of the signal and the possible processing of the signal can be found in the reference "Elektor", October 1980, page 10-44 ff.
  • radio clock proposed there is only suitable for a structure with a digital display, not for a structure with hands which provide an analog or quasi-analog display of the time.
  • a radio controlled clock with hands is known. It is provided that on the one hand the radio signal is fed to a computing circuit and on the other hand the content of a memory corresponds to the position of the pointer. The synchronization of the clock can be monitored by comparing the coded radio signal with the memory content at certain intervals.
  • the object of the invention is to provide a generic watch that adjusts itself automatically when the position of the hands does not match the actual time.
  • a radio-controlled watch which, on the one hand, obtains the time information from the coded radio signal and, according to the pulses, passes on the hands of a watch.
  • a quartz clock is controlled via the receiving part, which receives the radio impulses.
  • the quartz clock transmits indexing pulses to a control unit, which passes the pointers on.
  • the quartz clock takes over the switching of the hands in order to switch back to the radio signal control when the radio signal is received again.
  • a sensor is assigned to the hour and minute hands, and possibly also to the second hand, the sensors being provided stationary on the dial.
  • the sensors can preferably be reed relays that respond to small magnets that are integrated in the pointer.
  • other sensors for example on an optical basis, are also conceivable.
  • a comparison device checks each time the sensors overflow through the hands to determine whether the position of the hands matches the quartz time.
  • the sub-claims characterize a preferred embodiment of the watch.
  • a structure is described in subclaim 4, in which the pointer part of the clock with associated quartz clock is accommodated in a mobile unit, while the radio receiving part is accommodated in a stationary one Unit is provided.
  • the stationary unit consists of a conventional radio clock, which can also be used as a timer by electronically storing the manually entered switching times in a non-volatile memory.
  • the main task of the stationary unit is to send the current time information by radio, infrared or ultrasound.
  • the free-running quartz watch which controls the hands with the corresponding sensors, is accommodated in the mobile unit, which can expediently consist of a wristwatch.
  • the mobile unit also contains a suitable receiver for the signals from the stationary unit.
  • the mobile unit e.g. B. the wristwatch
  • the current time is passed through the information from the stationary unit to the mobile unit.
  • the mobile unit with quartz clock and pointer display can, if necessary, be compared again with the radio signal which contains the coded time information.
  • the method claims describe a method for operating the clock according to the invention.
  • the clock is set again.
  • the clock is also set immediately when switched on or even after a power failure.
  • the information about the pointer position is obtained in that minute pulses, with the presence of a second hand with the corresponding sensor, second pulses, are generated at an increased frequency until the sensors of the hands have detected the predetermined pointer position and a defined starting position is reached.
  • the use of reed relays has the advantage that the pointer position can be queried without energy consumption, and miniature switches and magnets can also be attached very small and compact to the pointer and dial. The reliability and resistance to the pointing are also cheaper than when using purely mechanical switching elements.
  • the radio clock controls the quartz clock and the quartz clock controls the hands.
  • the coincidence of the quartz clock and the position of the hands is monitored twice a day.
  • the figure shows a block diagram.
  • a receiving unit which receives the coded radio signal from an antenna.
  • the receiving unit controls a subsequent computing unit in which the radio signal is evaluated and the time information is filtered out of the coding of the radio signal.
  • the processing unit supplies this prepared time signal to a comparison unit.
  • This comparison unit measures whether there is a radio signal at all. If there is no radio signal, the comparison unit switches. to a free-running quartz clock, which also feeds its signal to the comparison unit. Is there a radio signal, the radio signal is constantly z. B. compared in minutes with the quartz clock signal, and in the event of deviations from one another, the quartz clock signal is synchronized with the radio signal.
  • the comparison unit controls a control unit which forwards the indexing pulses, one pulse per second at seconds, one pulse at minute hands per minute, to the pointers.
  • this signal is passed on via the comparison unit, but if the signal from the computing unit is missing, the quartz clock signal is fed to the control unit.
  • the watch activates a query which consists of the fixed sensors which poll the predefined pointer position of the watch every twelve hours.
  • the query is fed to an actuating unit, which also receives the quartz time. If the result of the query does not match the quartz time, the control unit in turn controls the control unit with increased frequency, so that fast pulses advance the clock until the clock, starting from the predetermined hand position, again indicates the time obtained from the comparison unit.
