<p>PROBLEM TO BE SOLVED: To correct a slave machine quickly even if the time information of a standard electronic wave changes discontinuously by setting reception time at the same time as specific switching time for a control means or at time later than it by short time and further setting transmission time to time that is later than the set time by short time. SOLUTION: Reception start means 13a of a control means 13 refers to the time information of a main counter 10 and outputs a reception start command at fixed time. An ON time counter 11 is started by the reception start command, and an ON/OFF means 12 transmits an ON signal to a reception circuit 2 for starting to receive signals. The received time data is read by a reception data accumulation means 6 to update the time of the main counter 10. In this case, when the discontinuous switching of standard time information has been scheduled, reception time is set simultaneously with specific switching time or at time later than it by short time. On the other hand, a transmission start means 13b sets transmission time at time later than the reception time that has been set to the reception start means 13 by short time, refers to the time information of the main counter 10 and outputs a transmission start command to a transmission circuit 14, and transmits time data to a slave machine.</p> |
