<p>PURPOSE:To restrict and cancel an input without a delay according to a traffic condition by comparing a reference value set beforehand with statistic data from a statistic processing means, and determining and notifying the time point of the start and cancellation of input restriction. CONSTITUTION:In a processing delay supervising device 3, by receiving output processing completion time information and input processing start time information read from a memory 5 by means of a restriction deciding part 6, a statistic processing part 4 calculates a differential time, executes the statistic processing with the former data, writes the statistic data of a processing result through the restriction deciding part 6 to the memory 5, and updates the statistic data. The restriction deciding part 6 compares the statistic data read from the memory at every constant time with the reference value, and when the statistic data are larger than the reference value, an input restriction starting signal is sent to a controller 2, an input restriction is started, when the statistic data are smaller than the reference value, an input restriction canceling signal is sent, and the input restriction is cancelled. Thus, the input restriction and cancellation can be executed without the delay according to the traffic.</p> |
