Abstract

A system is disclosed for accumulating data from a given number of meters. The data accumulating system is normally energized by a primary source of power for accumulating data with respect to the time of day. A clock is energized by the primary power source for providing a first time of day signal. Data from each of the meters is accumulated in its own counter. Processing means responsive to the time of day signal selectively accesses the counters and accumulates the data therefrom for specified intervals of time. Means responsive to the failure of the primary power source applies a secondary source of power to the clock to provide a second time of day signal. Upon restoration of the primary power source, the second time of day signal is transferred to the clock.
