(Outline of communication of air conditioning system)
Hereinafter, the air conditioning system according to each embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an example of an air conditioning system according to an embodiment of the present invention.
As shown in the figure, the air conditioning system includes indoor units 20A and 20B and wireless remote controllers 10A and 10B. The configurations of the indoor unit 20A and the indoor unit 20B are the same. The configurations of the wireless remote controller 10A and the wireless remote controller 10B are the same. The number of indoor units 20A and the like may be three or more, or one. The number of wireless remote controllers 10A and the like may be three or more, or one. When a plurality of indoor units 20A, etc. are provided, the plurality of indoor units 20A, 20B, etc. communicate with each other.

Of the plurality of indoor units 20A and the like, one is a base station. The base station controls communication between the wireless remote controller 10A and the like and the indoor unit 20A and the like. In the following description, the indoor unit 20A will be used as a base station. First, the base station relays communication between the devices. For example, when the wireless remote controller 10A and the wireless remote controller 10B are assigned to the indoor unit 20B, that is, when the indoor unit 20B can be set from both the wireless remote controller 10A and the wireless remote controller 10B, the user sets the wireless remote controller 10B. When the operation is performed, the wireless remote controller 10B transmits the air conditioning setting information to the indoor unit 20A. The indoor unit 20A receives this setting information and transmits it to the indoor unit 20B. The indoor unit 20B performs air conditioning control based on the setting information.

In addition, the base station leads the communication. Specifically, the base station allocates communicable time to each device of the indoor unit 20B and the wireless remote controllers 10A and 10B at predetermined time intervals. Devices other than the base station can communicate with the base station only during the allotted communicable time. When the communication available time is reached, the base station transmits a polling signal to the device to be communicated. With the transmission of the polling signal as an opportunity, communication between the base station and each device is started.

For example, even if the wireless remote controller 10A is assigned a communicable time and the wireless remote controller 10B is operated by the user while the wireless remote controller 10A is communicating with the indoor unit 20A which is a base station, the wireless remote controller 10B is operated. Communication between 10B and the base station (indoor unit 20A) is not started immediately. When the communicable time allocated to the wireless remote controller 10A has elapsed and the communicable time is allocated to the wireless remote controller 10B, the setting information related to the operation performed by the user earlier is transmitted from the wireless remote controller 10B to the indoor unit 20A. Then, the setting information transmitted to the indoor unit 20A is transmitted from the indoor unit 20A to the indoor unit 20B when the communicable time is allocated to the indoor unit 20B. As a result, the setting contents input by the user to the wireless remote controller 10B are transmitted to the indoor unit 20B. Similarly, the control information of the indoor unit 20B is transmitted to the base station when communicating with the indoor unit 20B. The latest control information of the indoor unit 20B and the latest setting information input to the wireless remote controllers 10A and 10B are transmitted to the base station that relays the communication of the air conditioning system. The base station stores this information. Next, when the communicable time of the wireless remote controller 10A arrives, the setting information for the indoor unit 20B previously input to the wireless remote controller 10B is transmitted from the indoor unit 20A to the wireless remote controller 10A. When the wireless remote controller 10A and the wireless remote controller 10B are operating in the normal mode, the wireless remote controller 10A and the wireless remote controller 10B communicate with the base station at predetermined time intervals and acquire the operating state of the indoor unit 20B from the base station. To do. Therefore, the wireless remote controller 10A and the wireless remote controller 10B share the latest operating state of the indoor unit 20B based on the latest setting information set for the indoor unit 20B.
In addition, in order to enhance the response to the user's operation, the base station may allocate the communicable time to the wireless remote controllers 10A and 10B more frequently than the indoor unit 20B.

By the way, the wireless remote controller 10A is driven by the rechargeable battery 12A. In order to suppress the power consumption of the rechargeable battery 12A, the wireless remote controller 10A shifts from the normal mode to the sleep mode when there is no operation from the user for a predetermined time or more. Generally, after the transition to the sleep mode, the wireless remote controller 10A does not communicate with the base station even when the communicable time allocated to itself arrives. For example, when the wireless remote controllers 10A and 10B are associated with the indoor unit 20B, that is, the start and end of the heating / cooling operation for the indoor unit 20B from any of the wireless remote controllers 10A and 10B, the setting of the indoor temperature, etc. When the operation of is possible, it is assumed that the wireless remote controller 10A shifts to the sleep mode after the wireless remote controller 10A is finally operated to set the indoor unit 20B (for example, cooling 28 ° C.). Then, when the user makes another setting (for example, cooling 26 ° C.) for the indoor unit 20B using the wireless remote controller 10B, the next time the user operates the wireless remote controller 10A, the wireless remote controller 10A is wirelessly set. The "cooling 28 ° C." displayed on the display unit of the remote controller 10A is different from the current operating state "cooling 26 ° C." of the indoor unit 20B.

Therefore, in the air-conditioning system of the present embodiment, even after the wireless remote controller 10A shifts to the sleep mode, the wireless remote controller 10A temporarily returns from the sleep mode at a predetermined timing, communicates with the indoor unit 20A which is a base station, and is a setting target. Acquire the latest control information of the indoor unit 20B.

(Composition of indoor unit)
Next, the functional configuration of the indoor unit 20A will be described. The indoor unit 20A includes a wireless communication circuit 21A, a control microcomputer 22A, a timekeeping circuit RTC23A, a sensor input circuit 24A, an actuator output circuit 25A, and an air conditioning control communication circuit 26A.
The wireless communication circuit 21A performs wireless communication with the wireless remote controllers 10A, 10B, the indoor unit 20B, and the like.

The control microcomputer 22A is a computer including a CPU and the like. The control microcomputer 22A controls the operation of the indoor unit 20A. Further, the control microcomputer 22A relays the communication of the wireless remote controllers 10A, 10B, the indoor unit 20B, etc. as a base station. The base station controls the communication. For example, the control microcomputer 22A allocates a communication available time to the wireless remote controllers 10A and 10B and the indoor unit 20B for each predetermined time, and communicates with each device via the wireless communication circuit 21A. Further, for example, when the wireless remote controller 10A shifts to the sleep mode, a polling signal is transmitted to the wireless remote controller 10A in synchronization with the return of the wireless remote controller 10A, and communication with the wireless remote controller 10A is started.

The timekeeping circuit RTC23A measures the time. The control microcomputer 22A allocates the communicable time to the wireless remote controller 10B and the indoor units 20A and 20B based on the time measured by the timekeeping circuit RTC23A. Further, the control microcomputer 22A allocates a communicable time to the wireless remote controller 10A in synchronization with the temporary return from the sleep mode of the wireless remote controller 10A based on the time measured by the timekeeping circuit RTC23A, and communicates with the wireless remote controller 10A.

The air conditioning control communication circuit 26A communicates a control signal with an outdoor unit (not shown).

(Wireless remote control configuration)
Next, the functional configuration of the wireless remote controller 10A will be described. The wireless remote controller 10A includes a power supply circuit 11A, a rechargeable battery 12A, a control microcomputer 13A, a wireless communication circuit 14A, a timing circuit RTC15A, an operation input circuit 16A, and an LCD display control circuit 17A.
The power supply circuit 11A converts the electric power supplied from the rechargeable battery 12A into a predetermined voltage and supplies it to the control microcomputer 13A and the like. The rechargeable battery 12A is a power source for the wireless remote controller 10A.

The control microcomputer 13A is a computer including a CPU and the like. The control microcomputer 13A controls various operations such as starting and stopping the wireless remote controller 10A and transmitting setting information input by the user. Further, the control microcomputer 13A switches the operation mode of the wireless remote controller 10A. For example, if there is no input to the operation input circuit 16A for a predetermined time, the control microcomputer 13A shifts the operation mode from the normal mode to the sleep mode. When the mode shifts to the sleep mode, the control microcomputer 13A suppresses power consumption by stopping the display on the display unit or the like. When the general wireless remote controller shifts to the sleep mode, the communication with the indoor unit also stops, but in the present embodiment, the control microcomputer 13A temporarily returns from the sleep mode at a predetermined timing and communicates with the base station. , Control to acquire the latest operating state of the indoor unit 20A or the like to be controlled. Further, when returning from the sleep mode to the normal mode, the control microcomputer 13A instructs the LCD display control circuit 17A to display the latest operating state acquired during the sleep mode on a display unit (not shown).

The wireless communication circuit 14A wirelessly communicates with the indoor units 20A, 20B and the like to be controlled via the base station.
The timekeeping circuit RTC15A measures the time. For example, the control microcomputer 13A temporarily returns from the sleep mode by an alarm interrupt generated at the return time set in the timekeeping circuit RTC15A.
The operation input circuit 16A accepts a user's operation on an operation button (not shown) included in the wireless remote controller 10A.
The LCD display control circuit 17A controls the display of a display unit (not shown) included in the wireless remote controller 10A.

Next, assuming that the wireless remote controller 10A is associated with the indoor unit 20B and the base station is the indoor unit 20A, the operation of the wireless remote controller 10A during sleep will be described.

(Control during sleep mode)
FIG. 2 is a diagram showing an example of operation of the wireless remote controller in the sleep mode according to the embodiment of the present invention.
First, on the wireless remote controller 10A, the control microcomputer 13A determines the transition to the sleep mode (step S1). In the indoor unit 20A which is a base station, when the communicable time of the wireless remote controller 10A arrives, the control microcomputer 22A transmits a polling signal to the wireless remote controller 10A via the wireless communication circuit 21A (step S2). The wireless communication circuit 14A receives the polling signal. By receiving the polling signal, the wireless remote controller 10A can communicate with the base station. When the determination of step S1 determines the transition to the sleep mode, the control microcomputer 13A instructs the wireless communication circuit 14A to transmit the sleep mode transition notification in response to the polling signal from the indoor unit 20A. The wireless communication circuit 14A transmits a sleep mode transition notification to the indoor unit 20A (step S3).

Further, the control microcomputer 13A sets a return time (for example, after 2 minutes) for returning from the sleep mode, and shifts the operation of the wireless remote controller 10A to the sleep mode (step S4). On the other hand, when the wireless communication circuit 21A receives the sleep mode transition notification in the indoor unit 20A, the control microcomputer 22A sets the remote control return time (step S5).

The remote control return time set by the control microcomputer 22A is a predetermined time from the return time set by the control microcomputer 13A by the wireless remote controller 10A in consideration of the time required for the wireless remote controller 10A to shift from the sleep mode to the normal mode. The future time may be set by α minutes. As a result, it is possible to prevent the indoor unit 20A from transmitting the polling signal to the wireless remote controller 10A before the temporary recovery from the sleep mode is completed.

The return time may be predetermined and the information may be shared between the indoor unit 20A and the wireless remote controller 10A. Alternatively, the wireless remote controller 10A may transmit the return time to the indoor unit 20A together with the sleep mode transition notification. Further, the wireless remote controller 10A may change the return time based on the remaining charge of the rechargeable battery 12A. Alternatively, the indoor unit 20A that has received the sleep mode transition notification may instruct the wireless remote controller 10A to return from the sleep mode. Further, the return time may be set according to, for example, the timing at which the communicable time is allocated to the wireless remote controller 10A.

An alarm based on the return time is set in the timekeeping circuit RTC15A with the transition to the sleep mode, and when the return time arrives, an interrupt signal indicating an alarm requesting the return is generated. By the interrupt signal, the control microcomputer 13A shifts (returns) from the sleep mode to the normal mode (step S6).

On the other hand, in the indoor unit 20A, even while the wireless remote controller 10A is operating in the sleep mode, communication between the indoor unit 20A, which is a base station, the indoor unit 20B, and the wireless remote controller 10B is performed for a predetermined time under the control of the control microcomputer 22A. It is repeated every time. For example, when the setting information of the indoor unit 20B is changed by the operation of the wireless remote controller 10B by the user, the latest setting information is transmitted from the wireless remote controller 10B to the indoor unit 20A, and the setting is made from the indoor unit 20A to the indoor unit 20B. Information is sent. Further, the latest control information of the indoor unit 20B is transmitted from the indoor unit 20B to the indoor unit 20A.

Further, the control microcomputer 22A monitors the time measured by the timekeeping circuit RTC23A, and transmits a polling signal when the remote control return time arrives (step S7). In the wireless remote controller 10A, when the wireless communication circuit 14A receives the polling signal, the control microcomputer 13A requests the latest operating state of the indoor unit 20B to be controlled. The wireless communication circuit 14A transmits a signal requesting the latest operating state to the indoor unit 20A (step S8). In the indoor unit 20A, the wireless communication circuit 21A receives a signal requesting the latest operating state. The control microcomputer 22A transmits the latest operating state (including setting information) of the indoor unit 20B to the wireless remote controller 10A via the wireless communication circuit 21A (step S10). In the wireless remote controller 10A, the control microcomputer 13A acquires the latest operating state of the indoor unit 20B via the wireless communication circuit 14A and stores this information. The operating state includes the operating mode of the indoor unit 20B such as cooling and heating, and the set temperature.

The control microcomputer 13A determines whether to shift to the normal mode or shifts to the sleep mode again (step S10), and operates in the determined mode. For example, when there is no user operation on the wireless remote controller 10A, the control microcomputer 13A shifts to the sleep mode again and repeats the processes after step S4. This makes it possible to prevent the rechargeable battery 12A from being consumed.

When there is a user operation on the wireless remote controller 10A, the operation input circuit 16A accepts this operation and outputs a signal corresponding to the user's operation content to the control microcomputer 13A. When the control microcomputer 13A acquires the signal corresponding to the user operation, the control microcomputer 13A returns from the sleep mode and shifts to the normal mode. The control microcomputer 13A instructs the LCD display control circuit 17A to display the latest operating state when shifting to the normal mode. The LCD display control circuit 17A displays the latest operating state of the indoor unit 20B on the display unit of the wireless remote controller 10A.

In the above example, it is assumed that the wireless remote controller 10A is associated with the indoor unit 20B, but even when the wireless remote controller 10A is associated with the indoor unit 20A, the wireless remote controller 10A can be used as a base station during the sleep mode by the same processing. The operating state of the indoor unit 20A to be controlled can be acquired.

As described above, in the present embodiment, even after the wireless remote controller 10A shifts to the sleep mode, it temporarily returns from the sleep mode at a predetermined timing, and communicates with the indoor unit 20A (base station) in synchronization with the return. , The latest operating state (setting information) of the indoor unit to be controlled (for example, the indoor unit 20B or the indoor unit 20A) is acquired from the indoor unit 20A. Further, when the wireless remote controller 10A shifts to the normal mode, the latest acquired operating state is displayed on the display unit. As a result, even if the operating state of the indoor unit 20A is changed while operating in the sleep mode, the latest operating state of the indoor unit 20A can be displayed when returning from the sleep mode. Therefore, it is possible to prevent user confusion.

Further, according to the present embodiment, when the wireless remote controller 10A decides to shift to the sleep mode, the wireless remote controller 10A and the indoor unit 20A determine the return timing, and transmit the latest operating state according to this timing. Do. Then, the wireless remote controller 10A immediately shifts to the sleep mode after acquiring the latest operating state. As a result, the power consumption of the rechargeable battery 12A can be minimized.

In the above embodiment, the wireless remote controllers 10A and 10B cannot spontaneously start communication, and communication is started from the base station at the timing when the wireless remote controller 10A temporarily returns, and within a short time. Although it was decided to update the state of the wireless remote controller 10A to suppress the current consumption, the wireless remote controller 10A may take the initiative to start communication with the indoor unit 20A. For example, the wireless remote controller 10A may temporarily recover and transmit a signal requesting the latest operating state to the indoor unit 20A during the time zone in which the wireless remote controller 10A in the sleep mode is assigned the communicable time.
