DE2829651A1 - Remote setting and time-keeping regulation for quartz timepiece - using transmitted serial binary coded signal timed by frequency divider from reference oscillator standard - Google Patents

Abstract

The setting of the time and the time-keeping regulation etc. of quartz timepieces is effected remotely via a coded signal transmitted via a programmer. The coded signal is transmitted via optoelectronic methods, via electromagnetic waves, acoustically inductively or capacitively. Each quartz timepiece may itself transmit stored information and a frequency obtained from the quartz oscillator to the programmer, which uses the received information to provide the time-keeping regulation signal. Pref. the information supplied by the programmer is transmitted as a serial binary coded signal.

Description

Adjusting, synchronizing and regulating device in particular

for electronically controlled clocks The invention relates to a device as can be found in the preamble of claim 1.

Adjusting, synchronizing and regulating devices for electronic Controlled clocks, especially for quartz clocks, have so far been operated manually: That These clocks are set and synchronized using one or more buttons, the regulation of the rate of these clocks is done by adjusting a trimmer capacity or e.g. by changing the division ratio of the frequency divider.

Particular disadvantages of known adjusting devices are that the manual setting process is sometimes cumbersome and time-consuming and incorrect operation does not exclude. Such an adjustment process can therefore - especially with digital clocks with several functions (hour, minute, second, weekday, day, month, year including Leap year) - take several minutes.

This adjustment process is with every battery change as well as with the industrial production disadvantageous for the reasons mentioned above.

The invention is based on the object of a device in particular for electronically controlled clocks in which setting, synchronizing and regulating a clock in the shortest possible time, preferably without contact.

In addition, operating errors should largely be excluded in these processes will. Furthermore, an automated production and testing of these watches should be made possible will.

Several clocks should be set, regulated and synchronized at the same time can be.

This object is achieved by the invention specified in claim 1 solved. Appropriate refinements of the invention can be found in the subclaims.

A particularly favorable embodiment of the invention results from the embodiment shown in the drawings.

They show: Fig. 1: the block diagram of a quartz clock with setting, Synchronizing and regulating device Fig. 2: the block diagram of a control device (Programming device) Description of the sequence control for actuating, synchronizing and Regulation process in the control unit and in the clock to be programmed: 1.) Start on Control unit 7 (triggering a pulse train) 2.) Detection pulses for gate time transmission are sent by pulse generator 9 3.) a gate time pulse (duration e.g. 1 s) from Gate time pulse generator 8 is via transmitter 10 for programming the frequency divider 21 sent 4.) Control unit 28 controls pulse separator 29, which controls the comparison counter 26 controls with the gate time pulse (see 3.): gate time of 8 is given to counter 26; During this time, the pulses derived from the crystal oscillator 20 are stored in the counter 26 counted; the bit pattern thus obtained is applied to the digital comparator 27 and is used to program the frequency divider 21 5.) via the control unit 7 the second synchronization pulse (at the output of frequency divider 2) with detection pulses from pulse generator 9 sent via the transmitter 10 and via the receiver 30 and the Control device 28 the programmable frequency divider 21 6) the recognition pulse generator 9, which is controlled by the control unit 7 is, is via the transmitter 10 and the receiver 30 control pulses to the pulse separator 29; Control generator 7 causes memory 13 to output the time information Transmitter 10, receiver 30, pulse separator 29 in the memory 25 and in the programmable Counter 22; the transmission of the time information takes place in the time between the first second synchronization pulse (see 5.) and the following second pulse (the occurs at the output of frequency divider 2) 7.)
