Management system, management method, operation terminal and control device

1. A management system comprising:

an operation terminal configured to perform a remote operation of an equipment; and

a control device configured to receive an access request from the operation terminal and transmit a request command to the equipment in response to reception of the access request, wherein

the operation terminal comprises a user interface configured to notify a user of information specifying an expiration timing of a response waiting timer that defines a transmission interval or a reception interval of the request command, and

a timer value set in the response waiting timer is determined according to contents of the request command.

2. The management system according to claim 1 , wherein

the operation terminal comprises a receiver configured to receive, from the equipment, information indicating the timer value set in the response waiting timer via the control device.

3. The management system according to claim 1 , wherein

the operation terminal comprises a receiver configured to receive, from the equipment, information indicating expiration of the response waiting timer via the control device.

4. The management system according to claim 1 , wherein

the equipment is a storage battery,

the request command includes an operation mode setting request command requesting a setting of an operation mode of the storage battery, and

the response waiting timer includes an operation mode resetting waiting timer applied to the operation mode setting request command.

5. A management method, comprising:

transmitting an access request from an operation terminal to a control device;

transmitting a request command from the control device to an equipment in response to reception of the access request;

transmitting a response command from the equipment to the control device in response to reception of the request command; and

notifying a user of information specifying an expiration timing of a response waiting timer from the operation terminal,

wherein

the response waiting timer is a timer that defines a transmission interval or a reception interval of the request command, and

a timer value set in the response waiting timer is determined according to contents of the request command.

6. An operation terminal, comprising:

a transmitter configured to transmit an access request to a control device that controls an equipment so as to remotely operate the equipment; and

a user interface configured to notify a user of information specifying an expiration timing of a response waiting timer,

wherein

the response waiting timer is a timer that defines a transmission interval or reception intervals of a request command transmitted from the control device to the equipment in response to the access request, and

a timer value set in the response waiting timer is determined according to contents of the request command.

7. A control device, comprising:

a first receiver configured to receive an access request from an operation terminal;

a first transmitter configured to transmit a request command to an equipment in response to reception of the access request;

a second receiver configured to receive, from the equipment, a response command corresponding to the request command; and

a second transmitter configured to transmit, to the equipment, information used for notification of information specifying an expiration timing of a response waiting timer,

wherein

the response waiting timer is a timer that defines a transmission interval or a reception interval of the request command,

the information specifying the expiration timing of the response waiting timer is notified to user from the operation terminal, and

a timer value set in the response waiting timer is determined according to contents of the request command.
