Title:
COMMUNICATION DEVICE, DATA ACQUISITION SYSTEM, DATA ACQUISITION CONTROL METHOD
Document Type and Number:
Japanese Patent JP2018174448
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the load on a system and obtain data at an appropriate timing for an application by dynamically changing a data acquisition method from a sensor according to the state of the system in a communication device, a data acquisition system, and a data acquisition control method that receive and control information with respect to the device.SOLUTION: A state detection unit 208 determine a system state such as a remaining battery level of a sensor 203 on the basis of a data acquisition request stored in a request history DB 205 via a request transmission/reception unit 204 and sensor data stored in a sensor history DB 207 via a sensor information acquisition unit 206. A data acquisition method change unit 209 changes a data acquisition method from the sensor 203 on the basis of the system state determined by the state detection unit 208. For example, the data acquisition method change unit 209 switches the data acquisition method between an on-demand data acquisition method and a change notification method on the basis of the system state.SELECTED DRAWING: Figure 2
