Detailed Description
An air conditioner control system according to an embodiment of the present invention will be described in detail below with reference to the drawings. The present invention is not limited to this embodiment.
Description of the embodiments
First, the configuration of the air conditioning control system 1 according to the embodiment will be described. Fig. 1 is a diagram showing a configuration of an air conditioning control system 1 according to an embodiment. The air conditioner control system 1 includes an air conditioner 2, a server 3, and an information terminal 4. The air conditioner 2 is connected to the server 3 via a network, and has a function of communicating with the server 3. The server 3 is also connected to the information terminal 4 via a network, and has a function of communicating with the air conditioner 2 and the information terminal 4. The information terminal 4 has a function of communicating with the server 3. The air conditioner 2 does not communicate with the information terminal 4.
The air conditioner 2 includes a first communication unit 21, and the first communication unit 21 has a function of communicating with the server 3. For example, the first communication unit 21 receives signals from the server 3 specifying the operating state, target temperature, and wind direction of the air conditioner 2. The air conditioner 2 further includes: a conversion unit 22 that converts the signal received by the first communication unit 21 into a signal that can be interpreted inside the air conditioner 2; and an internal communication section 23 that communicates with the conversion section 22.
The air conditioner 2 further includes a collection unit 24 that collects information related to the air conditioner 2. Examples of the information related to the air conditioner 2 are information indicating the operation state of the air conditioner 2, the temperature inside the room in which the air conditioner 2 is installed, the target temperature, and the wind direction. The internal communication section 23 also has a function of transmitting the signal received by the first communication section 21, which has been converted by the conversion section 22, to the collection section 24.
The internal communication section 23 also has a function of transmitting the information collected by the collection section 24 to the conversion section 22. The conversion unit 22 also has a function of converting the information transmitted from the internal communication unit 23 into a signal interpretable by the server 3. The first communication unit 21 also has a function of transmitting the signal, in which the information collected by the collection unit 24 is converted by the conversion unit 22, to the server 3. The period of the signal transmitted from the first communication unit 21 to the server 3 may be fixed, but may be changed.
The air conditioner 2 further includes a first control unit 25, and the first control unit 25 determines whether or not a signal received by the first communication unit 21 from the server 3 indicates start or stop of communication. When determining that the signal received by the first communication unit 21 from the server 3 indicates the start of communication, the first control unit 25 causes the first communication unit 21 to start the operation of transmitting the signal to the server 3. For example, the signal transmitted to the server 3 by the first communication section 21 is a signal in which the information collected by the collection section 24 is converted by the conversion section 22. When determining that the signal received by the first communication unit 21 from the server 3 indicates the stop of communication, the first control unit 25 stops the operation of the first communication unit 21 to transmit the signal to the server 3.
The air conditioner 2 further includes a detection unit 26, and the detection unit 26 detects a failure in the air conditioner 2 when the failure occurs. When the first communication unit 21 stops transmitting the signal to the server 3, the first control unit 25 causes the first communication unit 21 to start communication with the server 3 when the detection unit 26 detects a failure. That is, when the detection unit 26 detects a failure in the case where the transmission of the signal to the server 3 is stopped, the first communication unit 21 starts communication with the server 3. For example, when the first communication unit 21 stops transmitting the signal to the server 3, and the detection unit 26 detects a failure, the first communication unit transmits a signal indicating that the air conditioner 2 has failed to the server 3. When the first communication unit 21 transmits a signal to the server 3, the first communication unit may transmit a signal indicating that the air conditioner 2 has failed to the server 3 when the detection unit 26 detects a failure.
The server 3 has: a second communication unit 31 having a function of communicating with the air conditioner 2; a storage unit 32 for storing the signal received by the second communication unit 31; and a third communication unit 33 having a function of communicating with the information terminal 4. The storage section 32 is, for example, a semiconductor memory. The storage unit 32 also has a function of storing the signal received from the information terminal 4 by the third communication unit 33. The third communication unit 33 transmits the signal stored in the storage unit 32 to the information terminal 4 when the information terminal 4 requests the transmission of the signal stored in the storage unit 32.
When the third communication unit 33 receives a signal from the information terminal 4 specifying the operation state of the air conditioner 2, the target temperature, and a change in part or all of the wind direction, the storage unit 32 stores the signal received by the third communication unit 33. When the third communication unit 33 receives a signal for starting transmission of a signal from the air conditioner 2 to the server 3 from the information terminal 4, the storage unit 32 stores the signal for starting transmission of the signal from the air conditioner 2 to the server 3, and the second communication unit 31 transmits the signal for starting transmission of the signal from the air conditioner 2 to the server 3 to the air conditioner 2.
When the first communication unit 21 included in the air conditioner 2 receives a signal for starting transmission of a signal from the air conditioner 2 to the server 3, the first communication unit starts transmitting the signal to the server 3. The signal transmitted to the server 3 is, for example, a signal in which the information collected by the collection unit 24 is converted by the conversion unit 22.
The server 3 further includes a determination unit 34, and the determination unit 34 determines whether or not the time when the third communication unit 33 does not receive the signal from the information terminal 4 reaches a predetermined first time. When the determination unit 34 determines that the time when the third communication unit 33 does not receive the signal from the information terminal 4 reaches the first time, the second communication unit 31 transmits a first stop signal for stopping the transmission of the signal by the air conditioner 2 to the air conditioner 2. When receiving the first stop signal, the first communication unit 21 included in the air conditioner 2 stops transmitting the signal to the server 3.
The judgment unit 34 also has the following functions: a determination is made as to whether or not a predetermined second time has elapsed since the time when it is determined that the third communication unit 33 has not received the signal from the information terminal 4 reached the first time. When the determination unit 34 determines that the second time has elapsed since the time when the third communication unit 33 has not received the signal from the information terminal 4 reached the first time, the second communication unit 31 transmits a signal for starting transmission of the signal from the air conditioner 2 to the server 3 to the air conditioner 2. When the first communication unit 21 included in the air conditioner 2 receives a signal for starting transmission of a signal from the air conditioner 2 to the server 3, the first communication unit starts transmitting the signal to the server 3. The signal transmitted to the server 3 is, for example, a signal in which the information collected by the collection unit 24 is converted by the conversion unit 22.
The information terminal 4 includes: a receiving unit 41 that receives a user instruction; and a fourth communication unit 42 having a function of communicating with the server 3. The receiving unit 41 also has a function of displaying information. The receiving unit 41 is realized by a touch panel, for example. The reception unit 41 displays information based on the signal received from the server 3 by the fourth communication unit 42. The fourth communication unit 42 transmits a signal based on the instruction received by the reception unit 41 to the server 3. The information terminal 4 further includes a second control unit 43 for causing the fourth communication unit 42 to transmit a signal based on the instruction received by the reception unit 41 to the server 3. The instruction received by the receiving unit 41 is, for example, an instruction to start transmission of a signal from the air conditioner 2 to the server 3 or an instruction to stop transmission of a signal from the air conditioner 2 to the server 3.
When the reception unit 41 receives an instruction other than an instruction to stop the communication between the air conditioner 2 and the server 3 in the case where the communication between the air conditioner 2 and the server 3 is stopped, the fourth communication unit 42 transmits a first start signal for starting the communication between the air conditioner 2 and the server 3 to the server 3. In the server 3, when the third communication unit 33 receives the first start signal, the second communication unit 31 transmits a second start signal for causing the air conditioner 2 to start communication with the server 3 to the air conditioner 2. When receiving the second start signal, the first communication unit 21 included in the air conditioner 2 starts communication with the server 3.
When the reception unit 41 receives an instruction to stop communication between the air conditioner 2 and the server 3 in the case of transmitting a signal from the air conditioner 2 to the server 3, the fourth communication unit 42 transmits a second stop signal for stopping communication between the air conditioner 2 and the server 3 to the server 3. In the server 3, when the third communication unit 33 receives the second stop signal, the second communication unit 31 transmits a first stop signal for stopping the transmission of the air conditioner 2 to the air conditioner 2. When receiving the first stop signal, the first communication unit 21 included in the air conditioner 2 stops transmitting the signal to the server 3.
The air conditioner 2, the server 3, and a part of the plurality of components included in the information terminal 4 also have functions other than the above-described functions. The functions of some of the plurality of components other than the above functions will be described in the description of the operation of the air conditioning control system 1.
Next, the operation of the air conditioning control system 1 according to the embodiment will be described. Fig. 2 is a flowchart showing an example of the operation procedure of the air conditioner 2 included in the air conditioner control system 1 according to the embodiment. The first control unit 25 determines whether the first communication unit 21 has received a signal from the server 3 (S1).
When the first control unit 25 determines that the first communication unit 21 has received the signal from the server 3 (YES in S1), it determines whether or not the signal received by the first communication unit 21 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped (S2). In step S2 in fig. 2, it is determined whether or not the signal received by the first communication unit 21 indicates that the signal for stopping the transmission of the signal from the air conditioner 2 to the server 3 is described as "the content of the received signal is transmission stop? ".
When the first control unit 25 determines that the signal received by the first communication unit 21 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped (YES in S2), the first communication unit 21 stops the transmission of the signal to the server 3 (S3). When the first control unit 25 determines that the signal received by the first communication unit 21 is not a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped (NO in S2), it determines whether or not the signal received by the first communication unit 21 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is started (S4). In step S4 in fig. 2, it is determined whether or not the signal received by the first communication unit 21 indicates that the signal is to be transmitted from the air conditioner 2 to the server 3, and the signal is described as "the content of the received signal is the transmission start? ".
When the first control unit 25 determines that the signal received by the first communication unit 21 is a signal indicating that transmission of the signal from the air conditioner 2 to the server 3 is started (YES in S4), the first communication unit 21 starts transmitting the signal to the server 3 (S5). When the first control unit 25 determines that the first communication unit 21 has not received a signal from the server 3 (NO in S1), it determines whether or not the detection unit 26 has detected a failure (S6). When the first control unit 25 determines that the detection unit 26 has detected a failure (YES in S6), the first control unit 25 causes the first communication unit 21 to start communication with the server 3. That is, when the detection unit 26 detects a failure in the case where the transmission of the signal to the server 3 is stopped, the first communication unit 21 starts transmitting the signal to the server 3 (S5).
When the operation of step S3 is performed and when the first control unit 25 determines that the signal received by the first communication unit 21 is not a signal indicating the start of transmission of the signal from the air conditioner 2 to the server 3 (NO in S4), and when the operation of step S5 is performed and when the first control unit 25 determines that the detection unit 26 has not detected a failure (NO in S6), a series of operations of the air conditioner 2 are completed. When the series of operations is completed, the air conditioner 2 may perform a new series of operations from step S1 to step S6.
Fig. 3 is a flowchart showing an example of the procedure of the operation of the server 3 included in the air conditioning control system 1 according to the embodiment. The determination unit 34 determines whether or not the third communication unit 33 has received a signal from the information terminal 4 (S11). When it is determined that the third communication unit 33 has received the signal from the information terminal 4 (YES in S11), the determination unit 34 determines whether or not the signal received by the third communication unit 33 is a signal indicating that transmission of the signal from the air conditioner 2 to the server 3 is started (S12). In step S12 in fig. 3, it is determined whether or not the signal received by the third communication unit 33 is a signal indicating the start of transmission of the signal from the air conditioner 2 to the server 3, and the signal is described as "the content of the received signal is the start of transmission? ".
When the determination unit 34 determines that the signal received by the third communication unit 33 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is started (YES in S12), the second communication unit 31 transmits a signal for starting the transmission of the signal from the air conditioner 2 to the server 3 to the air conditioner 2 (S13). In step S13 in fig. 3, the transmission of a signal for starting the transmission of a signal from the air conditioner 2 to the server 3 to the air conditioner 2 is described as "transmission start to air conditioner".
When the first communication unit 21 included in the air conditioner 2 receives a signal for starting transmission of a signal from the air conditioner 2 to the server 3, the first communication unit starts transmitting the signal to the server 3. Thus, even if the transmission of the signal from the air conditioner 2 to the server 3 is stopped, the user can start the transmission of the signal from the air conditioner 2 to the server 3 by operating the information terminal 4. The signal transmitted from the air conditioner 2 to the server 3 is, for example, a signal obtained by converting information collected by the collection unit 24 in the air conditioner 2 by the conversion unit 22.
When it is determined that the signal received by the third communication unit 33 is not a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is started (NO in S12), the determination unit 34 determines whether or not the signal received by the third communication unit 33 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped (S14). In step S14 in fig. 3, it is determined whether or not the signal received by the third communication unit 33 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped, and the signal is described as "the content of the received signal is transmission stopped? ".
When the determination unit 34 determines that the signal received by the third communication unit 33 is a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped (YES in S14), the second communication unit 31 transmits a first stop signal for stopping the transmission of the signal from the air conditioner 2 to the air conditioner 2 (S15). In step S15 of fig. 3, transmission of the first stop signal for stopping transmission of the air conditioner 2 to the air conditioner 2 is described as "transmission stop to air conditioner".
When it is determined that the third communication unit 33 has not received a signal from the information terminal 4 (NO in S11), the determination unit 34 determines whether or not the time when the third communication unit 33 has not received a signal from the information terminal 4 has reached the first time (S16). In step S16 in fig. 3, it is determined whether or not the time at which the third communication unit 33 has not received the signal from the information terminal 4 has reached the first time described above is "whether or not the period of non-reception of the signal has reached a constant time? ".
When the determination unit 34 determines that the time when the third communication unit 33 has not received the signal from the information terminal 4 has reached the first time (YES in S16), the operation of the server 3 proceeds to step S15. When the operation of step S13 is performed and when the determination unit 34 determines that the signal received by the third communication unit 33 is not a signal indicating that the transmission of the signal from the air conditioner 2 to the server 3 is stopped (NO in S14), and when the operation of step S15 is performed and when the determination unit 34 determines that the time when the signal is not received by the third communication unit 33 from the information terminal 4 does not reach the first time (NO in S16), the series of operations of the server 3 is completed. When the series of operations is completed, the server 3 may perform a new series of operations from step S11 to step S16.
Fig. 4 is a flowchart showing an example of the procedure of the operation of the information terminal 4 included in the air conditioning control system 1 according to the embodiment. The second control unit 43 determines whether or not the receiving unit 41 receives the instruction from the user (S21). When it is determined that the receiving unit 41 has received the instruction from the user (YES in S21), the second control unit 43 determines whether or not the instruction received by the receiving unit 41 is an instruction to stop the transmission of the signal from the air conditioner 2 to the server 3 (S22). In step S22 in fig. 4, it is determined whether or not the instruction received by the reception unit 41 indicates that the instruction to stop the transmission of the signal from the air conditioner 2 to the server 3 is described as "the content of the instruction is transmission stop? ".
When the second control unit 43 determines that the instruction received by the reception unit 41 is not an instruction to stop the transmission of the signal from the air conditioner 2 to the server 3 (NO in S22), the fourth communication unit 42 transmits a signal to the server 3 indicating that the transmission of the signal from the air conditioner 2 to the server 3 is started (S23). In step S23 of fig. 4, the transmission of a signal indicating the start of transmission of a signal from the air conditioner 2 to the server 3 is described as "transmission start to server".
When the second control unit 43 determines that the instruction received by the reception unit 41 is an instruction to stop the transmission of the signal from the air conditioner 2 to the server 3 (YES in S22), the fourth communication unit 42 transmits a signal to stop the transmission of the signal from the air conditioner 2 to the server 3 (S24). In step S24 in fig. 4, the transmission of a signal indicating that the transmission of a signal from the air conditioner 2 to the server 3 is stopped is described as "stop transmission to server" to the server 3.
When the second control unit 43 determines that the instruction of the user is not received by the receiving unit 41 (NO in S21), when the operation in step S23 is completed, and when the operation in step S24 is completed, a series of operations of the information terminal 4 are completed. When the series of operations is completed, the information terminal 4 may perform a new series of operations from step S21 to step S24.
As described above, when the determination unit 34 determines that the time when the third communication unit 33 does not receive the signal from the information terminal 4 reaches the predetermined first time in the server 3, the second communication unit 31 transmits the first stop signal for stopping the transmission of the signal by the air conditioner 2 to the air conditioner 2. When the first communication unit 21 of the air conditioner 2 receives the first stop signal, it stops transmitting the signal to the server 3. Further, even when the user does not instruct the information terminal 4 to stop the transmission of the signal from the air conditioner 2 to the server 3, the first communication unit 21 stops the transmission of the signal to the server 3 when receiving the first stop signal. Therefore, the time when the first communication unit 21 stops transmitting the signal to the server 3 is generated. As a result, the air conditioning control system 1 can suppress an increase in the traffic.
As described above, when the first stop signal is received, the first communication unit 21 included in the air conditioner 2 stops transmitting the signal to the server 3. For example, the user does not use the information terminal 4 to remotely control the air conditioner 2 without using the air conditioner 2. That is, when the air conditioner 2 is not used, the third communication unit 33 included in the server 3 does not receive a signal from the information terminal 4. In this case, the first communication unit 21 included in the air conditioner 2 stops transmitting the signal to the server 3. Therefore, the air conditioning control system 1 can suppress the generation of useless communication. Further, the air conditioning control system 1 can suppress an increase in the traffic, and as a result, the cost for managing the server 3 depending on the traffic can be suppressed.
The first communication unit 21 transmits a signal to the server 3 until receiving the first stop signal. Therefore, the air conditioner control system 1 can cause the server 3 to hold the latest information as much as possible about the air conditioner 2.
In the air conditioner 2, when the first communication unit 21 stops transmitting a signal to the server 3, and the detection unit 26 detects a failure, communication with the server 3 is started. The signal transmitted to the server 3 is transmitted to the information terminal 4, and is displayed in the information terminal 4. Therefore, even if the communication between the air conditioner 2 and the server 3 is stopped, when the air conditioner 2 fails, the user of the information terminal 4 can recognize that the air conditioner 2 fails.
In the air conditioner control system 1, when the communication between the air conditioner 2 and the server 3 is stopped and the reception unit 41 of the information terminal 4 receives an instruction other than an instruction to stop the communication between the air conditioner 2 and the server 3, the fourth communication unit 42 of the information terminal 4 transmits a first start signal for starting the communication between the air conditioner 2 and the server 3 to the server 3. In the server 3, when the third communication unit 33 receives the first start signal, the second communication unit 31 transmits a second start signal for causing the air conditioner 2 to start communication with the server 3 to the air conditioner 2. When receiving the second start signal, the first communication unit 21 included in the air conditioner 2 starts communication with the server 3. Thus, even if the communication between the air conditioner 2 and the server 3 is stopped, the air conditioner control system 1 can start the communication between the air conditioner 2 and the server 3 when an instruction other than an instruction to stop the communication between the air conditioner 2 and the server 3 is input to the information terminal 4 by the user.
In the air conditioning control system 1, when the reception unit 41 of the information terminal 4 receives an instruction to stop communication between the air conditioner 2 and the server 3 in the case of transmitting a signal from the air conditioner 2 to the server 3, the fourth communication unit 42 of the information terminal 4 transmits a second stop signal for stopping communication between the air conditioner 2 and the server 3 to the server 3. In the server 3, when the third communication unit 33 receives the second stop signal, the second communication unit 31 transmits a first stop signal for stopping the transmission of the air conditioner 2 to the air conditioner 2. When receiving the first stop signal, the first communication unit 21 included in the air conditioner 2 stops transmitting the signal to the server 3. Thus, even if a signal is transmitted from the air conditioner 2 to the server 3, the air conditioner control system 1 can stop the air conditioner 2 from transmitting a signal to the server 3 when an instruction to stop communication between the air conditioner 2 and the server 3 is input to the information terminal 4 by the user. As a result, the air conditioning control system 1 can suppress an increase in the traffic.
