Description

[0001] The present invention relates to an external analog clock drive system,

More particularly, the present invention relates to a driving system for an indoor handpiece, and more particularly, to a system and method for automatically operating a hands-free timepiece by automatically receiving the best time information from a GPS (Global Positioning System), 40KHz long, 60KHz long, Time data is received through the received time information while receiving the time data while receiving the time data through the real time clock and compared with the time data displayed by the external needle clock, , 30 seconds, and 1 minute drive signals to display an accurate time through an external needle clock.

Generally, a clock generates a reference clock and divides it into hours, minutes and seconds, and then displays it visually through an LCD or an LED, or displays the time using the hours, minutes and seconds of a clock.

Such a watch maintains a relatively accurate time compared to a mechanical watch of the past, but it has a certain amount of error, so it displays a very wrong time with the passage of time.

Therefore, the user needs to calibrate the time from time to time, especially for industrial or technological clocks, which require frequent time correction.

To correct the time, press the button provided on the watch or turn the knob to set the standard time using the scheduled broadcast.

This time correction operation requires considerable care, so difficult and cumbersome work can not be avoided. In particular, when the time correction is frequently performed for industrial or scientific applications, the operation itself becomes very inconvenient.

In order to solve this inconvenience, Korean Patent Laid-Open No. 97-55659 proposes a method of recognizing the time signal of the radio and correcting the error by the recognized signal data.

In addition, Korean Patent Publication No. 96-38530 discloses a digital clock for recognizing a time signal broadcast on a radio or television and correcting a clock of a portable electronic clock, a home television or a video.

Korean Patent Laid-Open No. 96-18813 discloses a time adjusting device for detecting a time signal of a broadcasting station and correcting the time error by setting a reference value through a time-lapse time voltage level of 1 second.

U.S. Patent No. 4,582,434 suggests a clock that automatically scans several frequencies to select the strongest radio frequency and corrects the time difference by the microprocessor.

However, such conventional time correction apparatuses and methods all rely on timely broadcasting of radio or television. Since the times of these broadcasts are generally made in units of one hour, correction period is long, which is an obstacle to obtaining accurate time. Furthermore, it is necessary to use a high-sensitivity antenna to receive radio waves from these broadcasting stations. Even if an antenna is provided, it is difficult to receive radio waves in a hearing loss area or a shaded area. In particular, It is pointed out that the problem is impossible.

In addition, since devices continuously receiving broadcasts of these radios or televisions consume a considerable amount of power continuously, it is practically impossible to apply them to a portable watch because they can not use the battery as a power source.

Thus, Japanese Patent Application No. 10-1996-0059174 filed on November 28, 1996 (time automatic setting apparatus and method using time signal) has been proposed,

This includes a time signal reception step of receiving a time signal of a broadcast station,

A frequency detecting step of detecting a specific frequency repeated at predetermined time intervals in the signal reception step,

And a clock adjusting step of adjusting a clock when a predetermined number of specific frequencies are detected in the frequency detecting step,

Since it takes several steps to detect the time signal, the probability of occurrence of an error due to a specific frequency component of a specific broadcast is reduced and the external clock is also automatically adjusted.

The applicant of the present invention has proposed a utility model registration application No. 20-2006-0003651 (automatic time correction watch by ZPES) on February 09, 2006,

This includes an amplifier of a receiver for receiving and amplifying a GPS signal from a base station via an antenna,

A band-pass filter for removing an unnecessary signal from the amplified signal,

A frequency converter for converting the unnecessary signal into a frequency that can be detected when the signal is removed,

A detection unit for performing detection to extract only time data with respect to the frequency,

A microprocessor for controlling the operation of displaying and correcting the time when the detected time data is received as a digital signal through the analog / digital converter,

A time detector for extracting the instantaneous standard time data received under the control of the microprocessor,

A time calculator for calculating a current Korean time according to standard time data from the time detector under the control of the microprocessor,

A WATCH DOG TIMER for generating time data by frequency based on the frequency of the frequency from the oscillator under the control of the microprocessor and generating and transmitting time information on its own,

The first and second communication modems of the RS232C for transmitting and receiving information while transmitting the Korean time information to the controller of the clock in the microprocessor that has received the Korean time information from the time calculation unit,

A controller for receiving information including the Korean time information transmitted from the microprocessor and controlling an internal operation including display of time and display of operation,

An LCD driver for displaying a state according to a current operation on the liquid crystal display part under the control of the controller,

A dot lighting unit that is turned on under the control of the controller and displays AM or PM (PM)

A 3-state latch of an 8-bit serial input parallel output that outputs a drive signal for displaying two digits of time, minute and second while under the control of the controller,

And a plurality of transistor arrays for lighting the 7-segment display unit by a parallel output output through the 3-state latch of the 8-bit serial input parallel output, thereby generating a world time signal received from a satellite by a GPS (Global Positioning System) The standard time data can be always corrected to the correct time by comparing with the current counting time based on the standard, and all the characters are displayed clearly by the static method.

However, there is a tendency to prefer an analog clock that displays current time information through an hour hand, a minute hand, and a second hand, rather than a digital clock that displays time in numbers, such as an outer wall or a tower of a building.

The analog watch may not be accurate because of the irregular power supply and the lack of precision of the needle operation because the hour, minute and second hand needles continuously move to show the time flow.

Previously, when the position of the hour hand and the minute hand did not match the current time, it was confirmed by human eyes and corrected manually.

Also, in the case of analogue clocks installed in large analog clocks and large buildings (hospitals, government offices, airports, railroad history, port passenger terminals, etc.) provided with molding tower, complaints occur due to inaccurate time display, It is necessary to time and manpower to manage the clock.

Therefore, there is a need for a technique for an analog clock device capable of automatically correcting the time and providing an accurate time for such time display error and efficient rejection management.

Thus, Patent No. 10-1470597 (analog watch device having a time correction function) of December 02, 2014 has been proposed,

Comprising: a communication unit for receiving a signal from a GPS satellite and generating a current standard time information signal from GPS signal data;

A movement driver including a frequency divider dividing the oscillated waveform to generate a clearance pulse, and supplying the generated clear pulse to the movement driver to drive the movement;

A sensor unit for detecting the position of the minute hand and the hour hand to generate detection signals of the hour hand and the minute hand;

And a control unit for determining a time indicated by the current hour hand and the minute hand according to the detection signal and generating a correction control signal in comparison with the current standard time information signal,

The control unit may further include a real time clock (RTC). The real time clock (RTC) stores time information each time a current standard time information signal is received in the communication unit. When the power is on, And when the power supply is cut off, the power supply from the internal battery is supplied to operate the clock counter.

However, according to the analog watch device having the above-described conventional time correction function, the analog watch is corrected by the current time, but the hour hand rotates in conjunction with the minute hand while rotating the minute hand every 30 seconds or one minute by the motor There is a problem in that even if an error of several seconds is arbitrarily generated in the present time in a state of being driven by the gear, it can not be corrected accurately.

Furthermore, although the automatic long-wave reception automatic clock has been generalized and Korea is in the reception range of 60KHz and 40KHz Japanese longwave, it may be installed in the room or blocked in buildings or mountainous areas, And the GPS receiver is operated by pressing the force receiving button or the GPS receiving button several times, there are many cases where the GPS receiver is not turned on.
