Time watching apparatus for remote control system

Abstract

Abstract PURPOSE:To maintain the error of time information in each peripheral equipment within the allowable range by transmitting correct time information from a central unit to the peripheral equipments as desired. CONSTITUTION:Time information is exchanged between a central unit 11 and peripheral equipments 12 through transmission paths 29, and is compared with the standard time in the central unit 11. A controller 22 is adapted to correct the time information in each peripheral equipment 12 in accordance with a time correction information obtained as the result of the comparison. In each peripheral equipment 12, therefore, it is possible to easily and promptly correct the time indicated by clocks 33, 34 when the error is increased to exceed an allowable limit.
