Abstract

Status information including remaining battery power is collected from a management target device. Subsequent operations of the device are identified from an operation schedule management collection. Battery consumptions corresponding to subsequent operations of the device are estimated from KPI management collection that includes information representing relationships between battery consumptions and operations with respect to each of a plurality of devices. The battery life of the device is predicted based on the estimated battery consumptions and the remaining battery power represented by the collected status information. A circuit schedule of a maintenance engineer is determined based on the predicted battery life, the schedule including necessity of dispatch of the maintenance engineer to the device.

First claim

What is claimed is:

1. An energy saving device management method for improving accuracy of a management target device, comprising:
collecting, from the management target device, status information representing status that include remaining battery power of the device;
identifying a subsequent operation of the management target device, from operation schedule management information that is information representing schedules of operations of each of a plurality of management target devices;
estimating battery consumptions corresponding to subsequent operations of the device, from KPI management information that includes information representing relationships between battery consumptions and the operations with respect to each of the plurality of management target devices;
predicting battery life of the management target device, based on the estimated battery consumptions and the remaining battery power represented by the collected status information;
determining a circuit schedule of a maintenance engineer, based on the predicted battery life, the circuit schedule including necessity of dispatch of the maintenance engineer to the management target device;
creating an operation plan for reducing a period during which the remaining battery power of the device are insufficient, using the operation schedule management information and the circuit schedule, and updating the operation schedule management information in conformity with the operation plan;
providing the operation plan and the circuit schedule to a terminal of the maintenance engineer;
causing a date and time of executing an operation having a relatively high risk among the subsequent operations of the device to be close to a maintenance engineer dispatch date represented by the circuit schedule, based on risk management information representing a degree of risk of each operation;
determining whether or not there is an operation having an execution period to which the maintenance engineer dispatch date represented by the circuit schedule does not belong, based on operation requirement information representing the execution period of each operation; and
when there is an operation having the execution period to which the maintenance engineer dispatch date does not belong, scheduling an execution date of the operation to be a last day in the execution period of the operation.

2. The energy saving device management method according to claim 1 , further comprising:
determining whether or not there is an operation having an execution period to which a day before the maintenance engineer dispatch date represented by the circuit schedule belongs, based on the operation requirement information representing the execution period of each operation; and
when there is an operation having the execution period to which the day before the maintenance engineer dispatch date belongs, scheduling the execution date of the operation to be the day before the maintenance engineer dispatch date.

3. The energy saving device management method according to claim 1 , further comprising
determining achievability of the operation according to the remaining battery power and an operation type, and scheduling the operation on a day before the maintenance engineer dispatch date in a case where a sufficient battery power remains even after execution of the operation.

4. The energy saving device management method according to claim 1 , further comprising:
determining achievability of the operation according to the remaining battery power and an operation type, and scheduling the operation immediately after battery replacement in a case where execution of the operation is to exhaust the remaining battery power.

5. The energy saving device management method according to claim 1 , further comprising
updating KPI management information, based on a past operation history and a remaining battery power history of the device.

6. The energy saving device management method according to claim 1 , further comprising
setting priorities of the operations of the device according to importance of an IoT solution, and determining the schedule on a priority basis from the operations having high priorities.

7. An energy saving device management system for improving accuracy of a device management server, comprising:
the device management server capable of collecting, from a management target device, status information representing status including remaining battery power of the management target device, and of estimating battery consumptions corresponding to subsequent operations of the management target device, from KPI management information that represents relationships between battery consumptions and operations on each of a plurality of management target devices, and includes risk information;
a model part that predicts battery life, based on the estimated battery consumptions and the remaining battery power represented by the collected status information;
a maintenance manager that determines necessity of dispatch of a maintenance engineer to the device, and a circuit schedule, based on the predicted battery life;
a device controller that identifies subsequent operations of the management target device, from the circuit schedule determined by the maintenance manager, and from operation schedule management information that is information representing schedules of operations of each of the plurality of management target devices; and
an operation schedule management information that stores an operation plan created by the device controller using the risk information and the circuit schedule so as to reduce a period during which a state of the device is unknown due to the operation and updating the operation schedule management information in conformity with the operation plan, wherein
the maintenance engineer is allowed to view the created operation plan and the circuit schedule,
a date and time of executing an operation having a relatively high risk among the subsequent operations of the device is caused to be close to a maintenance engineer dispatch date represented by the circuit schedule, based on risk management information representing a degree of risk of each operation,
determining whether or not there is an operation having an execution period to which the maintenance engineer dispatch date represented by the circuit schedule does not belong, based on operation requirement information representing the execution period of each operation, and
when there is an operation having the execution period to which the maintenance engineer dispatch date does not belong, scheduling an execution date of the operation to be a last day in the execution period of the operation.
