Abstract

본 발명은 시계에 스스로 시간을 보정하는 기능을 부여하여 항상 정확한 시간을 유지할 수 있도록 하는 것을 목적으로 한다.An object of the present invention is to give a watch a function of correcting time by itself so that it can always maintain accurate time.

현재 대부분의 시계는 수정 진동자를 사용하여 과거의 기계식 시계보다는 훨씬 더 정확한 시간을 유지할 수 있으나 아직도 하루에 수초 정도는 틀릴 수 있다. 따라서 시계들을 가끔 보정하여 주어야 하나 요즈음은 각 가정에서 많은 시계를 사용하며 또한 라디오, 녹화기 등의 가전제품에도 시계가 붙어 나오는 경우가 많아 이들 모든 시계를 일일이 보정하여 주어 항상 정확한 시간을 유지시키는 것도 쉬운 일이 아니다. 이러한 문제점을 해결하여 주기 위해 본 발명은 시계에 라디오 방송국 또는 테레비전 방송국에서 정시에 방송되는 시보 신호를 이용하여 스스로 시간을 보정할 수 있는 기능을 갖추어 정확한 시간을 유지할 수 있도록 한다.Most watches now use crystal oscillators to maintain much more accurate time than mechanical watches of the past, but still be a few seconds a day. As a result, the clocks must be calibrated from time to time, but many clocks are used in homes these days, and many home appliances such as radios and recorders often come with clocks, so it is easy to maintain accurate time at all times. Not work In order to solve this problem, the present invention has a function capable of correcting the time by using a time signal that is broadcast on time at a radio station or a TV station, so that the time can be maintained accurately.

본 발명의 자동 보정 시계는 시간을 나타내는 별도의 코드 신호를 이용하는 것이 아니므로 특별한 방송국 또는 특별한 시간 코드 신호를 요구하지 않고서도 현재 일반 라디오 방송국 또는 테레비전 방송국에서 방송하는 정시를 알리는 시보 신호를 이용하여 정확한 시간을 유지할 수 있다.Since the automatic correction clock of the present invention does not use a separate code signal indicating a time, it does not require a special broadcasting station or a special time code signal, and thus, by using a time signal that informs the time of broadcasting by a general radio station or a TV station, Can keep accurate time.

Claims

Self-correcting clock that corrects the time by itself using the time signal that informs the time broadcast from a radio station or TV station.

2. The generator and timer according to claim 1, wherein the control means 1 controls the operation of the clock, the input means 2 for inputting information necessary for the operation, adjustment and control of the clock, the generator and the timer knowing the passage of time. A time function means 3 comprising: a time means means 3 for displaying the time and information necessary for control, a program for operating the clock, information about a station frequency, a time signal for notifying time, and time correction A storage means 5 capable of storing information necessary for control such as a time interval and a range of time for receiving a signal from a broadcasting station, a broadcasting station signal receiving means 6, the present detecting means 7, or the like; The clock itself, using the information about the time signal of the time signal of a given station, stored by the user or producer in the watch's storage means, for When a signal signal that is built in or connected to a clock is activated to receive a broadcast signal according to a frequency set to a predetermined broadcast station, and the control means or tone detection means of the clock checks and informs the time signal, Automatic correction clock, characterized in that the time is corrected to the time within the fixed time range of the hour, and this automatic time correction function is repeated to maintain accurate time

The automatic correction clock according to claim 2, wherein the time correction function operates within a predetermined time range determined by a timer to reduce power consumption.

The self-correcting clock according to claim 2, wherein the recognition of the time signal informing the on-time broadcast by the broadcasting station can be performed by at least one of the following methods a) to e). a) First, the storage in the time signal storage means is performed by the user operating the clock with the input means in accordance with the time when the broadcaster sends the time signal, so that the time signal is received from the broadcast signal receiving means, or at the production plant of the watch Is performed. At this time, the waveform of the time signal, that is, the change in the intensity of sound over time is stored in the storage means as it is. Subsequently, when the automatic time correction function is activated, some or all of the audio signal waveforms coming from the broadcasting station receiving means are judged to be the same time signal informing the same time when compared with the waveforms stored in the storage means. b) the user manipulates the clock with the input means in accordance with the time when the broadcasting station sends the time signal, so that the control means analyzes the time signal received by the station signal receiving means to construct the time signal, the frequency of the tone, the duration of the tone, Information on the time signal, such as the time interval between tones, is stored in the storage means.
