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.
Claims14
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 data acquisition unit that acquires the sensor signals from the sensors in a predetermined data acquisition period;
- a filter processing unit that performs a filtering process on the sensor signals acquired by the data acquisition unit;
- a transmitter that transmits time series data generated by extracting some of the sensor signals filtered by the filter processing unit to the external device in a predetermined data transmission period that is longer than the data acquisition period;
- and
- a timing control unit that synchronizes the data transmission period with a communication period of the external device.
A data sampling method for performing a sampling process on sensor signals from sensors and transmitting the sampled signals to an external device, the method comprising:
- a data acquisition step of acquiring the sensor signals from the sensors in a predetermined data acquisition period;
- a filter processing step of performing a filtering process on the acquired sensor signals;
- a transmission step of transmitting time series data generated by extracting some of the filtered sensor signals to the external device in a predetermined data transmission period that is longer than the data acquisition period;
- and
- a timing control step of synchronizing the data transmission period with a communication period of the external device.
