  • Measurement Of Unknown Time Intervals (AREA)

Abstract

PURPOSE: To realize a measurement of time inteval from the difference between the starting time and the finishing time of measurement, by expressing the time at the point of present spot by the contents of the counter and then latching the both times mentioned above.
CONSTITUTION: The counter 1 counts continuously the clocks S1 of a fixed cycle. The control circuit 3 delivers the latch signal S4 and the interruption request signal S5 in synchronization with the clock signal S1 during the rise and fall of the input signal S2. The latch circuit 2 latches the count value S6 of the counter 1 via the latch signal S4 in the form of the time signal at that time point. The microcomputer 4 detects via the signal S5 both the initiation and completion of the measurement and then reads it in the form of the output data S1 of the circuit 2 to store it into the RAM not shown in the figure. In the RAM starting and ending time of measurements stored. Accordingly, the time interval of measurement can be known from the initiation to the completion by calculating the difference between the two memory values.
