COMMUNICATION SYSTEM, RELAY APPARATUS, CONTROL APPARATUS, SERVER APPARATUS, CONTROL METHOD, AND INFORMATION PROCESSING METHOD
First Claim
1. A communication system comprising a terminal apparatus, a relay apparatus, and a control-target appliance,when said relay apparatus receives, from said terminal apparatus, a control instruction for controlling an operation of said control-target appliance, said relay apparatus setting a transmission interval of repeatedly transmitting, in order to detect a change in a status of said control-target appliance, a signal to said control-target appliance to be shorter than a preset time interval,based on said change in the status having been detected, said relay apparatus providing said terminal apparatus with notification of said status having been changed.

Abstract
A HEMS controller repeatedly transmits a predetermined signal to a control-target appliance at a set time interval in order to detect a change in a status of the control-target appliance. If the status changes, the HEMS controller notifies a smartphone of the changed status via a server apparatus. In a state where the time interval is set to a first time interval, when receiving a control instruction for controlling an operation of the control-target appliance from the smartphone via the server apparatus, the HEMS controller transmits the control instruction to the control-target appliance. In response to the transmission of the control instruction to the control-target appliance, the HEMS controller changes the time interval to a second time interval shorter than the first time interval.

1. A communication system comprising a terminal apparatus, a relay apparatus, and a control-target appliance,
when said relay apparatus receives, from said terminal apparatus, a control instruction for controlling an operation of said control-target appliance, said relay apparatus setting a transmission interval of repeatedly transmitting, in order to detect a change in a status of said control-target appliance, a signal to said control-target appliance to be shorter than a preset time interval, based on said change in the status having been detected, said relay apparatus providing said terminal apparatus with notification of said status having been changed.
-
11. A relay apparatus capable of communicating with a terminal apparatus and a control-target appliance,
when said relay apparatus receives, from said terminal apparatus, a control instruction for controlling an operation of said control-target appliance, said relay apparatus setting a transmission interval of repeatedly transmitting, in order to detect a change in a status of said control-target appliance, a signal to said control-target appliance to be shorter than a preset time interval, based on said change in the status having been detected, said relay apparatus providing said terminal apparatus with notification of said status having been changed.
-
12. A control apparatus capable of communicating with a server apparatus and a control-target appliance, comprising:
-
a first communication unit configured to repeatedly transmit a signal for detecting a change in a status of said control-target appliance to said control-target appliance at a set time interval and transmit a control instruction for controlling an operation of said control-target appliance to said control-target appliance when said first communication unit receives said control instruction from a terminal apparatus via said server apparatus; and a second communication unit configured to provide, based on said change in the status having been detected, said terminal apparatus with notification of said status having been changed, said notification being provided via said server apparatus, and a setting unit configured to set said time interval, when said first communication unit receives said control instruction from said terminal apparatus via said server apparatus while said time interval is set at a first time interval by said setting unit, said setting unit setting said time interval at a second time interval shorter than said first time interval.
-
-
13. A server apparatus capable of communicating with a terminal apparatus and a control apparatus for controlling a control-target appliance, comprising:
-
a storage unit configured to store data including identification information for said control-target appliance and a time interval that are associated with each other, said time interval defining a transmission interval of a signal used by said control apparatus in order to detect a change in a status of said control-target appliance; and a communication unit configured to, based on a control instruction for said control-target appliance having been received from said terminal apparatus, make reference to said data to provide said control apparatus with notification of said time interval associated with the identification information for said control-target appliance.
-
-
14. A control method for a relay apparatus capable of communicating with a terminal apparatus and a control-target appliance, the control method comprising the steps of:
-
receiving, from said terminal apparatus, a control instruction for controlling an operation of said control-target appliance; and when said control instruction is received, setting a transmission interval of repeatedly transmitting, in order to detect a change in a status of said control-target appliance, a signal to said control-target appliance to be shorter than a preset time interval.
-
-
15. A control method for a control apparatus capable of communicating with a server apparatus and a control-target appliance, the control method comprising the steps of:
-
repeatedly transmitting a signal for detecting a change in a status in said control-target appliance to said control-target appliance at a set time interval and transmitting a control instruction for controlling an operation of said control-target appliance to said control-target appliance when said control instruction is received from a terminal apparatus via said server apparatus; providing, based on said change in the status having been detected, said terminal apparatus with the notification of said status having been changed, said notification being provided via said server apparatus; and when said control apparatus receives said control instruction from said terminal apparatus via said server apparatus while said time interval is set at a first time interval, setting said time interval at a second time interval shorter than said first time interval.
-
-
16. An information processing method for a server apparatus capable of communicating with a terminal apparatus and a control apparatus for controlling a control-target appliance, said server apparatus storing data including identification information for said control-target appliance and a time interval that are associated with each other, said time interval defining a transmission interval of a signal used by said control apparatus in order to detect a change in a status of said control-target appliance,
the information processing method comprising the steps of: -
receiving a control instruction for said control-target appliance from said terminal apparatus; and based on said control instruction having been received, making reference to said data to provide said control apparatus with notification of said time interval associated with the identification information for said control-target appliance.
