測定値積算装置
Document Type and Number:
Japanese Patent JP6728003
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance the accuracy of measurement by measured value integrating devices without having to use a high-precision oscillator.SOLUTION: A measured value integrating device periodically samples input signals with a sampling clock generated from clocks and integrates measured values in each measuring period based on sample values obtained in a prescribed measuring period. Clocks are obtained by counting the number of clocks contained in each reference period prescribed with reference to time counting by an asynchronous chronometer part, correction coefficients are successively calculated on the basis of the obtained count value and a value calculated based on the nominal frequency of the clocks and the reference period, the measured values in each measuring period are corrected by using the latest correction coefficient, and the corrected measured values in each measuring period are integrated.SELECTED DRAWING: Figure 1
