Abstract

One aspect of the present invention acquires sensor data reflecting a motion state of a measurement object at a preset sample rate, estimates a feature amount representing the motion state from the acquired sensor data, compares the estimated feature amount with a determination index prepared in advance to generate determination information of the motion state, and variably sets a transmission parameter for transmitting the sensor data to a remote place for each sample on the basis of the generated determination information.

First claim

1 . A sensor data transmission device, comprising:
first processing circuitry configured to acquire sensor data reflecting a motion state of a measurement object at a preset sample rate; second processing circuitry configured to estimate a feature amount representing the motion state from the sensor data; third processing circuitry configured to compare the feature amount with a determination index prepared in advance to generate determination information of the motion state; and fourth processing circuitry configured to variably set a transmission parameter for transmitting the sensor data to a remote place for each sample on the basis of the determination information.

2 . The sensor data transmission device according to claim 1 , wherein:
the third processing circuitry determines whether the motion state is in a first state in which the motion state is deteriorating or in a second state in which the motion state is good by comparing the feature amount with a threshold value set as the determination index, and the fourth processing circuitry sets at least one of a transmission rate and an amount of transmission data as the transmission parameter to a first value when the motion state is determined to be the first state, and sets at least one of the transmission rate and the amount of transmission data to a second value lower than the first value when the motion state is determined to be the second state.

3 . The sensor data transmission device according to claim 1 , wherein:
the third processing circuitry calculates a difference between the feature amount representing the motion state and a target value set as the determination index, and the fourth processing circuitry variably sets the transmission parameter on the basis of the difference such that at least one of a transmission rate and an amount of transmission data decreases as the difference decreases.

4 . The sensor data transmission device according to claim 1 , wherein:
the second processing circuitry calculates a peak value of a norm of the sensor data as the feature amount representing the motion state.

5 . The sensor data transmission device according to claim 1 , further comprising:
a fifth processing circuitry configured to transmit the sensor data for each sample according to the transmission parameter.

6 . A remote terminal comprising:
the sensor data transmission device according to claim 1 ; and a sensor to measure the motion state of the measurement object and output the sensor data reflecting the motion state to the sensor data transmission device.

7 . A sensor data transmission method, comprising:
acquiring sensor data reflecting a motion state of a measurement object at a preset sample rate; estimating a feature amount representing the motion state from the sensor data; comparing the feature amount with a determination index prepared in advance to generate determination information of the motion state; and variably setting a transmission parameter for transmitting the sensor data to a remote place for each sample on the basis of the determination information.

8 . A non-transitory computer readable medium storing a program for causing a processor to perform the method of claim 7 .
