Abstract

In a modern control system, real time information is essentially required to assure reliable operation of the system. In this work, we propose a small-sized module, which is synchronized to a timecast provided by commercial broadcastings, for the purpose of distributing the accurate time information to the industrial field. The measurement results of a prototype module show that time difference from the national standard time is kept in thirty milliseconds under the normal condition.
