Sensor Device with Sampling Function, and Sensor Data Processing System Using Same

摘要

The sensor device includes a counter for counting the number of count commands used to perform measurements while maintaining among multiple sensor devices the ratio of measurement intervals; a ratio-holding-unit for setting the ratio to a desired ratio and holding respective values of the ratio for each of the multiple sensor devices; a sampling-timing-generating-unit for receiving a count value of the counter and the setting value of the ratio held by the ratio-holding-unit, and for generating a sampling timing signal based on the comparison result between the count value and the setting value; and a sampling-unit for sampling a detection signal detected by the detecting unit, by using the sampling timing signal generated by the sampling-timing-generating-unit.

1. A sensor device with sampling functionality comprising:
a counter for counting the number of count commands for performing measurements while maintaining among multiple sensor devices a ratio of measurement intervals; a ratio-of-measurement-intervals-holding-unit for holding a setting value of desired ratio of measurement intervals; a sampling-timing-generating-unit for generating sampling timing signal from count value of the counter and the setting value of the ratio of measurement intervals which value is held by the ratio-of-measurement-intervals-holding-unit, based on the comparison result between the count value and the setting value; and a sampling-unit for starting, according to the sampling timing signal generated by the sampling-timing-generating-unit, the sampling of detected signals of various types of information detected by detecting-unit.
