Abstract
To collect highly accurately filter-processed data. Sensor signals are acquired from sensors in predetermined data acquisition periods, a filtering process is performed on the sensor signals, time series data generated by extracting some of the filtered sensor signals is transmitted to an external device in a predetermined data transmission period that is longer than the data acquisition period, and the data transmission period is synchronized with a communication period of the external device.
Claims9
A data sampling device that performs a sampling process on sensor signals from sensors and transmits the sampled signals to an external device, the data sampling device comprising:
- a converter that acquires the sensor signals from the sensors in a predetermined data acquisition period;
- a filter that performs a filtering process on the sensor signals acquired by the converter;
- a transmitter that transmits time series data generated by extracting some of the sensor signals filtered by the filter to the external device in a predetermined data transmission period that is longer than the data acquisition period;
- a timing controller that synchronizes the data transmission period with a communication period of the external device;
- and
- a data generator that extracts some of the sensor signals filtered by the filter and generates the time series data,
- wherein the data generator extracts some of the sensor signals from the sensor signals filtered by the filter by acquiring the sensor signals transferred from the filter in a predetermined data transfer period that is different from the data acquisition period,
- wherein the data generator combines the sensor signals transferred in the data transfer period for a plurality of transfer periods and generates the time series data.
