Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Thus, detailed description thereof will not be repeated.

< first embodiment >

< overall Structure of network System 1 >

First, the overall configuration of the network system 1 according to the present embodiment will be described with reference to fig. 1. The network system 1 according to the present embodiment mainly includes: a server 300 for an application program for controlling a home appliance, and a communication terminal such as a smartphone 400 that exchanges various data with the server 300; and an air conditioner such as an air conditioner 100 that exchanges various data with the server 300 via the modem 500 and the WiFi (registered trademark) router 600.

The air conditioner may be the air conditioner 100 having a cooling and heating function, or may be an air cleaner having an air cleaning function, a humidifier having a humidifying function, another blower, or the like. The communication terminal is not limited to the smartphone 400, and may be a tablet computer, a game machine, a wearable terminal, a personal computer, or another communication device.

< summary of operation of network System 1 >

In particular, in the network system 1 according to the present embodiment, the home appliance control application of the smartphone 400 can acquire information of the air conditioner 100 via the server 300, or set or remotely control a timer command of the air conditioner 100. Hereinafter, a specific configuration of the network system 1 for realizing such a function will be described in detail.

< Structure of air conditioner 100 >

First, an embodiment of the configuration of the air conditioner 100 constituting the network system 1 will be described with reference to fig. 2. The air conditioner 100 according to the present embodiment includes, as main components: a CPU110, a memory 120, an LED lamp 130, an operation section 140, a communication interface 160, a speaker 170, a remote controller light receiving section 180, and a device driving section 190.

The CPU110 controls each unit of the air conditioner 100 by executing a program stored in the memory 120 or an external storage medium.

The memory 120 is implemented by various RAMs, various ROMs, and the like. The memory 120 stores a program executed by the CPU110, data generated by the CPU110 executing the program, data input via the operation unit 140, data received from the remote controller 199, data received from the server 300 via a router or the internet, and the like.

More specifically, the memory 120 according to the present embodiment includes: a memory area 121 for holding information related to a timer on command from the remote controller 199; a memory area 122 for storing information related to a timer off command from a remote controller; and a memory area 123 for holding information related to a timer command from the server 300. Further, a memory area 1231 is prepared, and the memory area 1231 stores information indicating whether or not the next command is stored in the server 300.

The LED lamp 130 is turned on based on a signal from the CPU 110. In the present embodiment, as shown in fig. 3, the CPU110 turns on the LED lamp 130 when the timer is set. When the timer reaches the time and a reservation command is executed, CPU110 turns off LED lamp 130. However, when the next timer command is accumulated in the server 300, the CPU110 turns on the LED lamp 130. After the timer is set, if the communication is interrupted for 24 hours or more, CPU110 turns off LED lamp 130.

Returning to fig. 2, the operation unit 140 is realized by a button or the like, receives a command from the user, and inputs the command to the CPU 110. The operation unit 140 may constitute a touch panel.

The communication interface 160 exchanges data between other devices through wired communication or wireless communication. That is, communication interface 160 receives data from CPU110 and transmits the data to another device such as server 300, or conversely, controls communication interface 160 to receive various data from another device and input the data to CPU 110. For example, the CPU110 periodically uploads information of the air conditioner 100 to the server 300 via the communication interface 160 or receives a control command from an application of the smart phone 400.

In particular, in the present embodiment, when executing a timer command with reference to the area 123 for storing information on one timer command from the server 300, the CPU110 requests a new timer command from the server 300 via the communication interface 160 with reference to the area 1231 for storing information indicating whether or not the next command is stored in the server 300. Further, the CPU110 rewrites the information area 123 for storing one timer command from the server 300 and the area 1231 for storing information indicating whether or not the next command is stored in the server 300, based on the data from the server 300.

The speaker 170 outputs various voices, sounds, melodies based on signals from the CPU 110.

The remote controller light receiving section 180 senses an infrared signal from a remote controller or the like and inputs a reception signal to the CPU 110. For example, the CPU110 receives a power on/off command, other control commands, various data, and the like from the remote controller via the remote controller light receiving section 180.

The device driving unit 190 controls each unit of the electric device, for example, a compressor, a fan, another motor, a heater, and the like based on a signal from the CPU 110. The air conditioner 100 according to the present embodiment realizes a cooling function, a heating function, an air blowing function, an ion generating function, and the like by the device driving unit 190.

In the present embodiment, the CPU110 of the air conditioner 100 periodically executes the following information processing. Referring to fig. 4, CPU110 refers to memory 120 and determines whether or not a time corresponding to a timer command from remote controller 199 has arrived (step S102). When the time corresponding to the timer command from remote controller 199 is reached (yes in step S102), CPU110 executes the timer command (step S104).

If the time equivalent to the timer command from remote controller 199 has not been reached (no in step S102), CPU110 determines whether or not the time equivalent to the timer command from server 300 has been reached (step S112). When the time corresponding to the timer command from server 300 has arrived (yes in step S112), CPU110 executes the timer command (step S114).

Based on the information 1231 indicating whether or not the timer command stored in the server 300 is present, and when the timer command stored in the server 300 is present (yes in step S116), the CPU110 requests the next timer command from the server 300 via the communication interface 160 (step S118).

When the time corresponding to the timer command from the server 300 is not reached (no in step S112), or when there is no timer command stored in the server 300 (no in step S116), the CPU110 waits until the next timing.

Further, it is preferable that the CPU110 of the air conditioner 100 stops the air conditioning operation when the air conditioning operation is executed by a command from the server 300 and then a first predetermined time, for example, 24 hours elapses after the communication is interrupted. Alternatively, it is preferable that CPU110 of air conditioner 100 stops the air conditioning operation in response to the command from server 300 when a first predetermined time, for example, 24 hours has elapsed since the interruption of communication, regardless of the duration of the air conditioning operation in response to the command from server 300. In addition, automatic cleaning of the filter, internal cleaning, air blowing, and the like may be performed for more than 24 hours. That is, it is preferable to end an operation that the user feels unpleasant (for example, there are air-conditioning operations such as a cooling operation and a heating operation that drive the compressor, and such an air-conditioning operation is an operation that increases power consumption and increases electricity charge when the operation is maintained, and therefore, the possibility that the user feels unpleasant is high). Alternatively, even if the operation is continued as it is to perform a safe operation (an operation in which a large current does not flow as in the case of driving the compressor, for example, the above-described automatic filter cleaning operation, the internal cleaning operation (an operation such as drying to prevent the heat exchanger of the indoor unit from getting mildewed), or the air blowing operation), the operation may be performed for more than 24 hours.

< Structure of Server 300 >

One embodiment of the configuration of the server 300 constituting the network system 1 according to the present embodiment will be described with reference to fig. 5. The server 300 includes the following components as main components: CPU310, memory 320, display 330, operation section 340, communication interface 360, and clock 380.

CPU310 controls each unit of server 300 by executing a program stored in memory 320. For example, the CPU310 executes various processes described later by executing programs stored in the memory 320 and referring to various data.

The memory 320 may be implemented by various RAMs, various ROMs, and the like, and may be incorporated in the server 300, may be attachable to and detachable from various interfaces of the server 300, or may be a recording medium of another device accessible from the server 300. The memory 320 stores a program executed by the CPU310, data generated by the CPU310 executing the program, input data, device data 321, device status data 322, pairing data 323, timer data 324, a database used for another home appliance management service according to the present embodiment, and the like.

As shown in fig. 6, the device data 321 includes, for each device such as the air conditioner 100: identification information of the device, a kind of the device, identification information of the user, a name for a specific room, an action command for a current action of the specific device, an action state such as various measurement results acquired by the sensor, and the like. CPU310 refers to device data 321 and provides information on a device disposed in a designated room, out of devices paired with smartphone 400, based on a request from an application program of a communication terminal such as smartphone 400.

As shown in fig. 7, the device state data 322 may store the ID of the device, the current operation state of the device, and the number of times of switching on/off the operation for each device. Here, the operation to be switched on/off may be a heating operation, a cooling operation, an air blowing operation, an ion generating operation, an air cleaning operation, a humidifying operation, or the like, or may be another operation. Alternatively, only the number of times of on/off switching of the power supply may be used. When the operation of the device is switched on/off, CPU310 provides the current operation state to the communication terminal paired with the device via communication interface 360. Further, the operating state includes: an instruction to be executed by air conditioner 100, a timer instruction passed to air conditioner 100, information indicating whether or not the next instruction is stored in server 300 stored in air conditioner 100, measurement data of various sensors, and the like.

As shown in fig. 8, the pairing data 323 contains an ID of pairing and discrimination information of paired devices from each other in each combination of devices. For example, the correspondence relationship between the air conditioner 100 and the smartphone 400 for remotely controlling the air conditioner 100 or the identification information of the user is included.

As shown in fig. 9, the timer data 324 stores a timer ID, a device ID, a timer time, a timer command, a repeat setting, and the like for each timer command input to an application of a communication terminal such as the smartphone 400. The repetition setting corresponds to an application of the smartphone 400, and includes information for repeating the same timer command every day, information for repeating the same timer command every week, and the like. The timer data 324 preferably stores information indicating whether or not the air conditioner 100 stores the next command in the server 300 for each timer command.

Returning to fig. 5, display 330 displays text and images based on signals from CPU 310. The operation unit 340 receives a command from a service manager or the like and inputs the command to the CPU 310.

The communication interface 360 transmits data from the CPU310 to other devices such as the air conditioner 100 and the smartphone 400 via the internet, a carrier network, a router, and the like. In contrast, communication interface 360 receives data from other devices via the internet, a carrier network, a router, etc. and interfaces to CPU 310.

CPU310 of server 300 according to the present embodiment executes the following information processing when receiving data from a device such as air conditioner 100 via communication interface 360.

Referring to fig. 10, the CPU310 reads the identification information of the device from the received data (step S302). The CPU310 determines whether or not the data from the device this time is a request for the next timer command (next timer command) (step S304). If the request is for the next timer command (yes in step S304), CPU310 refers to timer data 324, and determines whether or not there is data of the timer command accumulated for the device, for example, a repeated timer command, a one-time timer command, or the like (step S306).

If there is data of a timer command stored for the device (yes in step S306), the CPU310 refers to the timer data 324 and determines whether or not the next timer command (successive timer command) is stored (step S308). When the next timer command is accumulated (yes in step S308), the CPU310 transmits data indicating the first timer command and the substance of the next timer command accumulated to the device via the communication interface 360 (step S310).

CPU310 waits to accept data from the next device.

More specifically, in the present embodiment, an application program of a communication terminal such as the smartphone 400 can receive a plurality of kinds of repetitive timer commands or a timer command only once for each device such as the air conditioner 100. That is, a plurality of timer commands are stored in the timer data 324 of the server 300 for each device. However, the memory 120 of the air conditioner 100 or the like may hold only one timer command from the server 300. Therefore, in the present embodiment, the CPU110 of the air conditioner 100 receives the first timer data and the data indicating that the next timer data is stored from the server 300 via the communication interface 160, and stores them in advance in the area 123 and the area 1231, the area 123 storing one command from the server 300, and the area 1231 storing information indicating that the next command is stored in the server 300. As in step S114 of fig. 4, when the timer command is executed or when the stored timer command is present (yes in step S116), the CPU110 acquires the next timer command from the server 300 via the communication interface 160 (step S118).

Returning to fig. 10, if the next timer data is not stored (no in step S308), CPU310 transmits the first timer data and data indicating that the next timer data is not stored to the device via communication interface 360 (step S312). CPU310 waits to accept data from the next device. In addition, in the case where there is no timer command (no in step S306), the CPU310 also waits for reception of data from the next device.

If the received data is not the request for the next timer command (no in step S304), CPU310 determines whether the received data indicates the current operating state of the device, the on/off count, or the like (step S322). When the received data indicates the current operating state of the device and the count of on/off described above (yes in step S322), CPU310 accumulates the current operating state of the device and the count of on/off in device state data 322 (step S324).

When the on/off count is increased from the previous value (yes in step S326), CPU310 refers to device data 321 and transmits the current operating state to one or more communication terminals paired with the device via communication interface 360 (step S328). CPU310 waits to accept data from the next device.

If the received data does not indicate the current operating state of the device, the count of on/off, or the like (no in step S322), CPU310 executes another process (step S330) and waits for reception of data from the next device.

< Structure of smartphone 400 >

An embodiment of the configuration of a communication terminal such as a smartphone 400 according to the present embodiment will be described with reference to fig. 11. The smartphone 400 includes the following components as main constituent elements: CPU410, memory 420, display 430, operation unit 440, communication interface 460, speaker 470, microphone 480, and the like.

CPU410 controls each section of smartphone 400 by executing a program stored in memory 420.

The memory 420 is implemented by various RAMs, various ROMs, and the like. The memory 420 stores programs executed by the CPU410, for example, an application program for home appliance control, data generated by the CPU410 executing the programs, input data, a database used for other home appliance management services according to the present embodiment, and the like.

Display 430 displays text and images based on signals from CPU 410. Operation unit 440 receives a command from a user or the like and inputs the command to CPU 410. For example, CPU410 causes display 430 to display an operation screen based on an application program for controlling a home appliance such as air conditioner 100, and receives an input of a remote control command to air conditioner 100 via operation unit 440. In addition, the display 430 and the operation portion 440 may be touch panels.

Communication interface 460 transmits data from CPU410 to another device such as server 300 via the internet, a carrier network, a router, or the like. Instead, communication interface 460 receives data from the other device via the internet, a carrier network, a router, etc. and interfaces to CPU 410.

Speaker 470 outputs voice based on data from CPU410, and microphone 480 accepts voice and inputs voice data to CPU 410.

In the present embodiment, CPU410 receives an instruction from a user via operation unit 440, and starts an application program for controlling a home appliance. The CPU410 receives data related to the paired air conditioners 100 from the server 300 via the communication interface 460, and as shown in fig. 12, the display 430 displays the data related to the air conditioners 100. CPU410 receives a command for air conditioner 100 via operation unit 440, and transmits the command to server 300 via communication interface 460. The server 300 controls the air conditioner 100 based on the command.

In the present embodiment, as shown in fig. 13, CPU410 receives via operation unit 440: when the air conditioner 100 is operated or stopped by the operation of the remote controller 199 for a room, when timer setting is executed from an application program, the on/off of a mode reached from the server 300 is notified, and "registration information change" is performed for a member,

The "device delete" is a notification of the setting of on/off of the mode that arrives, and the like.

Since the network system 1 according to the present embodiment is configured as described above, the following processing is executed. First, a communication terminal such as the smartphone 400 stores the timer command in the server 300 by remote setting. When air conditioner 100 stores information indicating that the next command is stored in server 300, server 300 waits for a request for the next timer command from air conditioner 100, and when it is not stored, transmits the timer command to air conditioner 100. The air conditioner 100 receives this information and causes the LED lamp indicating the presence of the next command to be turned on. Further, the server 300 may acquire various information from the air conditioner 100 at the timing. The air conditioner 100 lights the LED for the timer until all the accumulated timer commands are completed.

For example, when a timer command is input in advance, or when a new timer command that does not overlap is input, as shown in fig. 14 (a), (1) the user sets the new timer command via the smartphone 400. (2) The server 300 transmits a message that a new timer command exists to the air conditioner 100. At this time, since there is a timer inputted in advance, the air conditioner 100 lights up an LED lamp for the timer. (3) Air conditioner 100 responds to server 300 with the following: the timer command is received. (4) The server 300 displays the following subjects: air conditioner 100 normally receives the presence of the timer command.

As shown in fig. 14 (b), when the previous timer setting time is reached, the air conditioner 100 executes the previous timer command and requests the next timer command to the server 300. In this case, server 300 further notifies air conditioner 100 that its next timer command is not present. At this time, since there is the next timer command, the air conditioner 100 lights the LED lamp for the timer. Thus, when the next timer set time is reached, (1) the air conditioner 100 executes the next timer command, as shown in (c) of fig. 14. (2) Also, since there is no next timer command, the air conditioner 100 turns off the timer LED.

Next, when a timer command is input in advance, or when a timer command that repeats every day is input, as shown in fig. 15 (a), (1) the user sets a new timer command via the smartphone 400. (2) The server 300 transmits a message that a new timer command exists to the air conditioner 100. At this time, since there is a timer inputted in advance, the air conditioner 100 lights up an LED lamp for the timer. (3) Air conditioner 100 responds to server 300 with the following substance: the timer command is received.

(4) The server 300 displays the following subjects: air conditioner 100 normally receives the presence of the timer command.

As shown in (b) of fig. 15, when the air conditioner 100 executes a previous timer command, a next timer command is requested to the server 300. In this case, server 300 further notifies air conditioner 100 that its next timer command is present. At this time, since there is the next timer command, the air conditioner 100 lights the LED lamp for the timer. Thus, when the next timer setting time is reached, (1) the air conditioner 100 executes the next timer command, (2) and the next timer command is present, as shown in fig. 15 (c), the timer LED is kept lit.

Next, when a timer command for repeating every day that the heating operation is on at 7 am and a timer command for repeating every day that the heating operation is off at 8 am are input, the server 300 transmits the timer command for 7 am to the air conditioner 100 as shown in fig. 16 (a). In this case, the air conditioner 100 is notified that the next timer command is present. At this time, since there is a timer at 7 am, the air conditioner 100 turns on an LED lamp for the timer. Thus, when the timer set time of 7 am is reached, CPU110 turns on the heating operation and the next timer command at 8 am is present as shown in fig. 16 (b), and therefore requests server 300 for the next timer command as shown in fig. 16 (c). In this case, server 300 further notifies air conditioner 100 that its next timer command is present. At this time, since there is a timer (next timer) at 8 am, the air conditioner 100 turns on an LED lamp for the timer. Thus, when the timer setting time is reached, as shown in fig. 16 (d), the CPU110 turns off the heating operation and requests the server 300 for a timer command at 7 o' clock on the next tomorrow. In this case, server 300 further notifies air conditioner 100 that the next timer command next thereto exists. At this time, since there is a timer at 7 am (and further, the next timer), the air conditioner 100 turns on the LED lamp for the timer. In this way, when the timer is set to be repeated every day, the timer LED is kept lit.

< second embodiment >

In the first embodiment, if yes in step S326 of fig. 10, step S328 is executed immediately. However, in the present embodiment, as shown in fig. 17, when the on/off count is increased from the previous value (yes in step S326), CPU310 waits for a random time, for example, a time longer than 0 second and shorter than 10 minutes (step S327). The CPU310 refers to the device data 321, and transmits the current operation state to one or more communication terminals paired with the device via the communication interface 360 (step S328). Thus, even if a timer is set by many users at the time of the interruption, the requests for the air conditioner 100 are not concentrated and the maximum load of the server 300 and the network communication can be reduced. Alternatively, the device may wait for a predetermined time period instead of a random time period. When the predetermined time is determined at the time of production of the air conditioner 100, one time may be set for each air conditioner 100 within a range of a random time, for example, a time longer than 0 second and shorter than 10 minutes.

< third embodiment >

Other devices may perform a part or all of the functions of the devices of the network system 1 according to the first and second embodiments. For example, other devices may be responsible for part or all of the respective functions of the server 300, the air conditioner 100, and the smartphone 400, or a plurality of devices may share part or all of the respective functions of these devices. For example, although air conditioner 100 determines that the timer time has come, the determination of a part thereof may be determined on the application program side of server 300 or smartphone 400, or the processing of server 300 may be processed by smartphone 400 or air conditioner 100.

< summary >

In the embodiment, an air conditioner 100 is provided with: a communication interface 160 for communicating with the server 300; a memory 120 for storing commands from the timer of the server 300; and a processor 110 for acquiring and storing first information indicating a subject of a timer from the server 300 when a command of the next timer is present, when the command of the timer from the server 300 is received via the communication interface 160.

Preferably, the air conditioner 100 further includes a lamp 130. The processor 110 lights or blinks the lamp 130 when the first information is stored.

Preferably, the processor 110 requests the server 300 for a next timer command via the communication interface 160 when executing the received timer command from the server 300 when the first information is stored.

Preferably, when the first information is stored, the processor 110 waits for an arbitrary period of time from 0 second to a predetermined time period when executing a received command of the timer from the server 300, and then requests the server 300 for a command of the next timer via the communication interface 160. The predetermined time is, for example, 10 minutes, 5 minutes, 1 minute, 30 minutes, and a time unit of the interrupt which is easily set by the user. In addition, the prescribed time may be preset at the time of production.

Preferably, processor 110 stops air conditioning operation or transitions to a safe state when a first predetermined time or longer continues in a state where communication with server 300 is interrupted or when a second predetermined time elapses from execution of a command from a timer of server 300 in a state where communication with server 300 is interrupted.

According to another aspect of the present invention, there is provided a network system 1 including the air conditioner 100 and the server 300. The air conditioner 100 transmits the current state to the server 300 at predetermined intervals.

Preferably, the network system 1 further includes a communication terminal 400. The communication terminal 400 accepts a command of a timer from a user and transmits the command to the server 300. When the on/off of the predetermined air conditioning operation of the air conditioner 100 is switched, the server 300 transmits the current state of the air conditioner 100 to the communication terminal 400.

Preferably, the server 300 transmits the current state of the air conditioner 100 to the plurality of communication terminals 400 paired with the air conditioner 100 when switching on/off of a predetermined air conditioning operation of the air conditioner 100.

The embodiments disclosed herein are in all respects illustrative and should not be considered as limiting the invention. The scope of the present invention is defined by the claims, not by the description above, and is intended to include meanings equivalent to the claims and all modifications within the scope.
