Data collection system

1. A gateway device collecting data from a plurality of devices and transmitting the data to a server device, the gateway device comprising at least one processor configured to implement:

a thinning unit configured to select a plurality of transmission target devices from among the plurality of devices; and

a communication unit configured to transmit the data of the transmission target devices to the server device,

wherein the processor is configured to further implement an interpolation possibility determination unit configured to determine a possibility of interpolation of values of the data of the devices having not been selected as the transmission target devices by using the data of the transmission target devices, on a basis of a history of the data of the transmission target devices, and

wherein the interpolation possibility determination unit is configured to, on a basis of the possibility of the interpolation, control whether or not the thinning unit selects all of the plurality of devices as the transmission target devices.

2. A gateway device collecting data from a plurality of devices and transmitting the data to a server device, the gateway device comprising at least one processor configured to implement:

a thinning unit configured to select a plurality of transmission target devices from among the plurality of devices; and

a communication unit configured to transmit the data of the transmission target devices to the server device,

wherein the processor is configured to further implement an interpolation possibility determination unit configured to determine a possibility of interpolation of values of the data of the devices having not been selected as the transmission target devices by using the data of the transmission target devices, on a basis of a history of the data of the transmission target devices, and

wherein the interpolation possibility determination unit is configured to, on a basis of whether or not the possibility of the interpolation is present, determine whether or not to transmit the data of some of the plurality of devices to the server device.

3. A gateway device collecting data from a plurality of devices and transmitting the data to a server device, the gateway device comprising at least one processor configured to implement:

a thinning unit configured to select a plurality of transmission target devices from among the plurality of devices; and

a communication unit configured to transmit the data of the transmission target devices to the server device,

wherein the thinning unit is configured to, before selecting the transmission target devices, for each of a plurality of thinning patterns, use the data of the transmission target devices to estimate, by interpolation, the values of data of the devices not to be selected as the transmission target devices, compare the estimated values with the values of the data of the devices not to be selected as the transmission target devices to determine a possibility of the interpolation, and decide a thinning pattern that a thinning rate becomes largest or becomes equal to or more than a threshold from among thinning patterns that a possibility of the interpolation is present, the thinning rate being a ratio of a number of the devices not to be selected as the transmission target devices to a total number of the plurality of devices.

4. A gateway device collecting data from a plurality of devices and transmitting the data to a server device, the gateway device comprising at least one processor configured to implement:

a thinning unit configured to select a plurality of transmission target devices from among the plurality of devices; and

a communication unit configured to transmit the data of the transmission target devices to the server device,

wherein the thinning unit is configured to decide a thinning rate according to a condition of a load on a network between the gateway device and the server device, the thinning rate being a ratio of a number of the devices not to be selected as the transmission target devices to a total number of the plurality of devices.

5. A gateway device collecting data from a plurality of devices and transmitting the data to a server device, the gateway device comprising at least one processor configured to implement:

a thinning unit configured to select a plurality of transmission target devices from among the plurality of devices; and

a communication unit configured to transmit the data of the transmission target devices to the server device,

wherein the thinning unit is configured to determine a possibility of interpolation of values of the data of the devices having not been selected as the transmission target devices by using the data of the transmission target devices, on a basis of a history of the data of the transmission target devices and, according to the determined possibility of the interpolation, decide a thinning rate that is a ratio of a number of the devices not to be selected as the transmission target devices to a total number of the plurality of devices.

6. A method executed by a gateway device configured to collect data from a plurality of devices and transmit the data to a server device, the method comprising:

selecting a plurality of transmission target devices from among the plurality of devices; and

transmitting the data of the transmission target devices to the server device,

the method further comprising, in selecting the transmission target devices, before selecting the transmission target devices, for each of a plurality of thinning patterns, using the data of the transmission target devices to estimate, by interpolation, values of the data of the devices not to be selected as the transmission target devices, comparing the estimated values with the values of the data of the devices not to be selected as the transmission target devices to determine a possibility of the interpolation, and deciding a thinning pattern that a thinning rate becomes largest or becomes equal to or more than a threshold from among thinning patterns that a possibility of the interpolation is present, the thinning rate being a ratio of a number of the devices not to be selected as the transmission target devices to a total number of the plurality of devices.
