Control system, control apparatus, object apparatus, and control method

A control apparatus configured to communicate with an object apparatus provided in a facility, comprising:

• a transmitter configured to transmit a request command to the object apparatus, wherein the object apparatus comprises at least one of a photovoltaic power generation apparatus, a fuel cell apparatus, or a hot-water storage apparatus, and wherein the request command comprises
• a first information element that requests a second information element indicating a state of the object apparatus, wherein the state comprises at least one of a power generation amount of the photovoltaic power generation apparatus, a power generation amount of the fuel cell apparatus, or a hot-water storage amount of the hot-water storage apparatus,
• a range acquisition information element that requests a range of values relating to an ability of the object apparatus, wherein the range of values comprises operation modes of the object apparatus, and
• an object information element indicating object content of the range;
• a receiver configured to receive a request response command from the object apparatus, wherein the request response command comprises
• the second information element requested by the first information element,
• a range information element indicating the range, and
• the object information element and
• a controller configured to control the object apparatus based on the second information element, the range information element, and the object information element.

An object apparatus provided in a facility and configured to receive a command from a control apparatus, comprising:

• at least one of a photovoltaic power generation apparatus, a fuel cell apparatus, or a hot-water storage apparatus;
• a receiver configured to receive a request command from the control apparatus, wherein the request command comprises
• a first information element that requests a second information element indicating a state of the object apparatus, wherein the state comprises at least one of a power generation amount of the photovoltaic power generation apparatus, a power generation amount of the fuel cell apparatus, or a hot-water storage amount of the hot-water storage apparatus,
• a range acquisition information element that requests a range of values relating to an ability of the object apparatus, wherein the range of values comprises operation modes of the object apparatus, and
• an object information element that indicates object content of the range;
• and
• a transmitter configured to transmit a request response command to the control apparatus, in response to reception of the request command, wherein the request response command comprises
• the second information element requested by the first information element,
• a range information element indicating the range, and
• the object information element,
• wherein the object apparatus is controlled by the control apparatus based on the second information element, the range information element, and the object information element.

A control method used in a control system including an object apparatus provided in a facility and a control apparatus configured to communicate with the object apparatus by transmitting a command to the object apparatus, the control method comprising:

• transmitting a request command, from the control apparatus to the object apparatus, wherein the object apparatus comprises at least one of a photovoltaic power generation apparatus, a fuel cell apparatus, or a hot water storage apparatus, and wherein the request command comprises
• a first information element that requests a second information element indicating a state of the object apparatus, wherein the state comprises at least one of a power generation amount of the photovoltaic power generation apparatus, a power generation amount of the fuel cell apparatus, or a hot-water storage amount of the hot-water storage apparatus
• a range acquisition information element that requests a range of values relating to an ability of the object apparatus, wherein the range of values comprises operation modes of the object apparatus, and
• an object information element that indicates object content of the range;
• transmitting a request response command, from the object apparatus to the control apparatus, in response to reception of the request command, wherein the request response command comprises
• the second information element requested by the first information element,
• a range information element indicating the range, and
• the object information element and,
• by the control apparatus, controlling the object apparatus based on the second information element, the range information element, and the object information element.
