Abstract
A management server 103 holds a parameter of a sensor device 101 and change management information related to a change in the parameter, and transmits the changed parameter and the change management information to the sensor device. The sensor device 101 holds the parameter and the change management information transmitted from the management server, and transmits the change management information to the management server together with measurement data. The management server collates the received change management information and preliminarily-held change management information to determine the change in the parameter on the basis of a result of the collation.
Claims11
A sensor device management method in which measurement data measured by a sensor device is obtained and managed by a management server, comprising:
- holding a parameter of the sensor device and change management information related to a change in the parameter in the management server, and transmitting the changed parameter and the change management information to the sensor device,
- holding the parameter and the change management information transmitted from the management server in the sensor device, and transmitting the change management information to the management server together with the measurement data, and
- collating in the management server the received change management information and preliminarily-held change management information to determine the change in the parameter on the basis of a result of the collation.
A sensor device management system in which a management server obtains and manages measurement data measured by a sensor device, comprising:
- the management server including:
- a first storage unit that holds a parameter of the sensor device and change management information related to a change in the parameter;
- and
- an interface that transmits the changed parameter and the change management information to the sensor device,
- the sensor device including:
- a sensor;
- a second storage unit that holds the parameter and the change management information transmitted from the management server;
- and
- a communication unit that transmits a packet including measurement data including data measured by the sensor and the change management information to the management server, and
- wherein the management server further includes a determination unit that collates the received change management information and preliminarily-held change management information to determine the change in the parameter on the basis of a result of the collation.
