Abstract

A communicator communicates with a plurality of management targets. An operation-mode determiner determines, based on information representing a status of each of the management targets each received by the communicator, whether a total system status of the plurality of management targets satisfies a predefined condition. A mode-of-network-communication switch, a communication-parameter changer, a condition-for-device-communication setter, a cycle-for-obtaining-status-value setter and a communication-parameter setter adjust, when the operation-mode determiner determines that the system status satisfies the predefined condition, a communication status of the communicator in accordance with the system status and a processing performance of the device.

Claims

1. A management device comprising:

a communicator configured to communicate with a plurality of management targets;

a determiner configured to determine, based on information representing a status of each of the management targets each received by the communicator, whether a total system status of the plurality of management targets satisfies a predefined condition; and

an adjuster configured to adjust, when the determiner determines that the system status satisfies the predefined condition, a communication status of the communicator in accordance with the system status and a processing performance of the management device.

2. The management device according to claim 1, further comprising a system controller configured to control, based on the information representing the status of each of the management targets each received by the communicator, each of the management targets.

3. The management device according to claim 1, wherein:

the plurality of management targets include a device configured to consume power, a power supply system configured to supply power to the device, and a power measuring device configured to measure power consumed by the device;

the predefined condition includes a condition relating to power; and

the adjuster adjusts, when the determiner determines that the system status satisfies the condition relating to power, the communication status of the communicator in such a way that at least one of a communication frequency for a measured value by the power measuring device and a communication frequency for a control instruction to suspend the device or to suppress a performance thereof, increases.

4. The management device according to claim 3, wherein the condition relating to power includes at least one of followings:

a rate of power consumption relative to a power limit value;

a status of supplied power from the power supply system; and

a fact whether a blackout is occurring.

5. The management device according to claim 1, wherein:

the plurality of management targets include a device configured to consume power, a power supply system configured to supply power to the device, and a power measuring device configured to measure power consumed by the device;

the predefined condition includes a setting of a control mode that controls the device based on power supplied from the power supply system; and

the adjuster adjusts, when the determiner determines that the control mode is set, the communication status of the communicator so as to increase a transmission frequency for information on supplied power from the power supply system and to decrease a communication frequency for polling to the device.

6. The management device according to claim 1, wherein:

the predefined condition includes that a number of the management targets is equal to or greater than a predefined number; and

the adjuster adjusts, when the determiner determines that the number of the running management targets is equal to or greater than the predefined number, the communication status of the communicator so as to decrease a communication frequency with each of the management targets.

7. The management device according to claim 1, wherein the adjuster narrows down, when the determiner determines that the system status satisfies the predefined condition and when requesting the information representing the status of each of the management targets to each of the management targets, a kind of requesting information.

8. The management device according to claim 1, wherein the adjuster changes at least one of a priority of a communication with each of the management targets and a cycle of polling to each of the management targets by the communicator to adjust the communication status of the communicator.

9. A management system comprising:

the management device according to claim 1, and

the plurality of management targets configured to communicate with the management device.

10. The management system according to claim 9, wherein the plurality of management targets include a power generation system, a power storage system, a device configured to consume power, and a measure configured to measure a predetermined physical quantity.

11. A management method utilizing a management device including a communicator communicating a plurality of management targets, the method comprising:

a determining process of causing the management device to determine, based on information representing a status of each of the management targets each received by the communicator, whether a total system status of the plurality of management targets satisfies a predefined condition; and

an adjusting process of causing the management device to adjust, when determining in the determining process that the system status satisfies the predefined condition, a communication status of the communicator in accordance with the system status and a processing performance of the management device.

12. A non-transitory computer-readable recording medium for storing a program causing a computer to function as:

a communicator configured to communicate with a plurality of management targets;

a determiner configured to determine, based on information representing a status of each of the management targets each received by the communicator, whether a total system status of the plurality of management targets satisfies a predefined condition; and

an adjuster configured to adjust, when the determiner determines that the system status satisfies the predefined condition, a communication status of the communicator in accordance with the system status and a processing performance of the computer.
