Abstract

PURPOSE: To enable time change without manual operation, by advancing the time count memory in the processor with the clock signal and correcting the content of time count memory from the count value of back-up counter on mains failure.
CONSTITUTION: In time control with the ON-line processing system such as telemetering, the clock signal from the original oscillator 1 is fed to the processing unit 4 fetching the data and the back up counter 6. Further, the time count memory 5 in the unit 3 is advanced with the clock signal and the content of the memory 5 is corrected from the count value of the counter 6 on mains failure. Thus, with a simple circuit constitution, the time change can be made without manual operation.
