[ air-conditioning apparatus 10]
As shown in fig. 2, the air conditioner 10 includes an air conditioning unit 11, a receiving unit 12, a control unit 13, a display unit 14, and a storage unit 15. The air conditioning unit 11 adjusts at least one property of the temperature, humidity, and airflow of the air.
The reception unit 12 receives air-conditioning settings related to the air-conditioning unit 11. Specifically, the reception unit 12 includes, for example, a communication unit 121 and an infrared light receiving unit 122. The communication unit 121 receives a signal including air conditioner settings transmitted from the operation terminal 20 via a Network 30 including a wired LAN (Local Area Network) or a wireless LAN. The infrared light receiving unit 122 receives an infrared signal including air conditioning settings transmitted from a remote controller not shown.
The control Unit 13 includes a processor such as a CPU (Central Processing Unit). The control unit 13 acquires the air-conditioning setting included in the signal received by the communication unit 121 or the air-conditioning setting included in the infrared signal received by the infrared light receiving unit 122, and controls the air-conditioning unit 11 based on the acquired air-conditioning setting.
The display unit 14 is, for example, a liquid crystal display, and displays a display related to air-conditioning setting under the control of the control unit 13. Specifically, the control unit 13 generates an air-conditioning setting image including a temperature, a humidity, and the like indicating air-conditioning setting, and causes the display unit 14 to display the image. The air conditioning setting image may include the air volume and the wind direction of the air conditioning unit 11, in addition to the temperature and the humidity.
In addition, for example, the display unit 14 may be one or more LED lamps. In this case, the control unit 13 controls the lighting and lighting of the corresponding LED lamp based on the air-conditioning setting. Specifically, the control unit 13 changes the lighting color of the LED lamps or the number of the LED lamps to be lit according to the air-conditioning setting.
The storage unit 15 stores various data. For example, the storage unit 15 stores a control program for operation of the air conditioner 10. The control unit 13 executes a control program to control the operation of the air conditioner 10.
[ operation terminal 20]
The operation terminal 20 includes a control unit 21, a storage unit 22, a display unit 23, an operation unit 24, and a communication unit 25. The control unit 21 controls the storage unit 22, the display unit 23, the operation unit 24, and the communication unit 25.
The control Unit 21 includes a processor such as a CPU (Central Processing Unit).
The storage unit 22 stores various data. For example, the storage unit 22 stores a control program for driving the operation terminal 20. The control unit 21 controls the operation of the operation terminal 20 by executing a control program.
The storage unit 22 may store an application program related to control of the air conditioner 10. For example, the control unit 21 may execute an application program to control the air conditioner 10.
The display unit 23 displays an operation screen and results of various processes. The display section 23 includes a liquid crystal display or an organic EL display.
The operation unit 24 may include a touch sensor. The display unit 23 and the operation unit 24 may be integrated into a touch panel. Various keys for indicating, for example, the type of job and the content of the job are displayed on the touch panel. Alternatively, the operation unit 24 may include buttons or a keyboard.
The communication unit 25 communicates with an external device. Here, the communication unit 25 transmits at least a specific signal to the air conditioner 10 via the network 30. The communication unit 25 may receive at least a specific signal from the air conditioner 10.
For example, the communication unit 25 transmits a signal including air conditioning settings of the air conditioner 10 to the air conditioner 10. Specifically, when the user operates the operation unit 24 in accordance with the screen displayed on the display unit 23 by execution of the application program and inputs the air-conditioning setting of the air-conditioning apparatus 10 to the operation terminal 20, the control unit 21 generates a signal including the input air-conditioning setting. The communication unit 25 transmits a signal including the air conditioning setting generated by the control unit 21 to the air conditioner 10 via the network 30.
[ Limit settings ]
In the present embodiment, a setting range can be set for the air conditioner. For example, in the air conditioner 10 having an adjustable temperature range of 15 to 30 ℃, a limit setting may be provided to limit the temperature setting range to 20 to 26 ℃. The limitation setting is not limited to the temperature setting range, and may be a setting for prohibiting a change of the operation contents that can be executed by the air conditioner 10, such as the cooling operation.
Specifically, in order to set the limit setting for the air conditioner 10, for example, the user operates a remote controller, and an infrared signal including a limit setting instruction instructing the setting of the limit setting is transmitted from the remote controller to the air conditioner 10. Inclusion in the restriction settings indication represented 20 deg.C
26 ℃ is the information of the limited range.
The reception unit 12 of the air conditioner 10 receives a restriction setting for restricting a change of the executable operation content. Specifically, the infrared light receiving unit 122 receives an infrared signal including a restriction setting instruction transmitted from a remote controller.
The control unit 13 acquires a restriction setting instruction included in the infrared signal received by the infrared receiving unit 122, and stores the restriction setting instruction in the storage unit 15. The control unit 13 controls the air conditioning unit 11 based on the restriction setting instruction stored in the storage unit 15.
Specifically, the control unit 13 controls the temperature of the air in the air conditioning unit 11 so that the adjustment range is within the limit range (20 to 26 ℃). For example, in the air conditioner 10, when the air conditioning setting (temperature setting) before the restriction setting is accepted is 20 ℃, the control unit 13 maintains 20 ℃ of the air conditioning setting (temperature setting), and controls the air conditioning unit 11 based on the maintained air conditioning setting. On the other hand, when the air conditioning setting (temperature setting) before the restriction setting is accepted is 19 ℃, the control unit 13 changes the air conditioning setting (temperature setting) to 20 ℃, and controls the air conditioning unit 11 based on the changed air conditioning setting. In this way, in the air-conditioning apparatus 10, the state in which the air-conditioning unit 11 operates based on the restriction setting is referred to as a restricted state.
In the present embodiment, the restriction setting instruction is not limited to the remote controller, and may be transmitted from the operation terminal 20. For example, when the user operates the operation unit 24 in accordance with a screen displayed on the display unit 23 by execution of the application program, the control unit 21 causes the display unit 23 to display a restriction input screen for requesting the user to input a restriction range set for the air conditioner.
When the user operates the operation unit 24 in accordance with the restriction input screen displayed on the display unit 23 to input the restriction range to the operation terminal 20, the control unit 21 generates a restriction setting instruction generated in the remote controller and generates a signal including the restriction setting instruction. The communication unit 25 transmits a signal including the restriction setting instruction generated by the control unit 21 to the air conditioner 10 via the network 30.
As shown in fig. 1, when the air conditioning system 100 includes a plurality of operation terminals 20, at least one of the operation terminals 20 is a management terminal having a management authority capable of transmitting a restriction setting instruction. In the air conditioning system 100, the operation terminal 20 other than the management terminal cannot transmit the restriction setting instruction. Hereinafter, the operation terminal 20 other than the management terminal may be referred to as a normal terminal.
[ Account ]
In the present embodiment, at least one account is set in the air conditioning system 100. The account is set for each user who can operate the air conditioner 10. At least one operation terminal 20 is registered in each account.
Specifically, when the account is set to a user who can operate the air conditioner 10 by a certain user, the user executes an application program stored in the operation terminal 20. When the user operates the operation unit 24 in accordance with the screen displayed on the display unit 23 by execution of the application program, the control unit 21 generates a signal including account information in which the user ID for identifying the user and the terminal ID for identifying the operation terminal 20 are associated with each other. The communication unit 25 transmits a signal including the account information generated by the control unit 21 to the air conditioner 10 via the network 30.
The communication unit 121 of the air conditioner 10 receives a signal including account information transmitted from the operation terminal 20. The control unit 13 acquires account information included in the signal received by the communication unit 121, and stores the account information in the storage unit 15.
In this way, the state in which the account information corresponding to a certain user is stored in the storage unit 15 is the state in which an account is set. In the account information, the state in which the user ID and the terminal ID are associated with each other is set to a state in which the operation terminal 20 is registered in the account.
In the present embodiment, a plurality of operation terminals 20 can be registered in one account. Specifically, when account information having the same user ID as certain account information and having a different terminal ID is stored in the storage unit 15, a state is assumed in which a plurality of operation terminals 20 are registered in the corresponding account.
In the present embodiment, the account information may include information indicating whether the corresponding operation terminal 20 is a management terminal or a normal terminal. For example, when setting an account, the user selects whether the operation terminal 20 is a management terminal or a normal terminal according to a screen displayed on the display unit 23 by executing an application program.
When the user selects the management terminal, the control unit 21 generates account information including information indicating that the corresponding operation terminal 20 is the management terminal. On the other hand, when the user selects the normal terminal, account information including information indicating that the corresponding operation terminal 20 is the normal terminal is generated.
[ granting of management Authority ]
In the air conditioning system 100, when the management terminal is one and the other operation terminal 20 is a normal terminal, for example, when the power supply of the management terminal is turned off, when the user holding the management terminal moves out of the communication range of the network 30 and the communication between the management terminal and the air conditioner 10 is turned off, when the management terminal disappears from the account, or when the account registered by the management terminal is deleted, the setting, the change, and the cancellation of the restriction setting cannot be performed.
In order to avoid this, the management terminal can give a management authority to another normal terminal.
Next, referring to fig. 3 and 4, the assignment of management authority will be described. Fig. 3 is a diagram showing a state before the management authority is given to another normal terminal. Fig. 4 is a diagram showing another normal terminal to which management authority is given. In fig. 3 and 4, a management terminal having a management authority is indicated by an asterisk.
For example, in the air conditioning system 100, an account of the user a, an account of the user B, and an account of the user C are set.
In the account of the user a, the operation terminal 20 having the terminal ID "a1" is registered as a management terminal having a management authority. In addition, in the account of the user a, the operation terminal 20 having the terminal ID "a2" is registered as a normal terminal having no management authority. Hereinafter, the account in which the management terminal is registered is referred to as a management account.
In the account of the user B, the operation terminal 20 having the terminal ID "B" is registered as a normal terminal having no management authority.
In the account of the user C, the operation terminal 20 having the terminal ID "C" is registered as a normal terminal having no management authority.
For example, the four operation terminals 20 are registered in the order of "a1", "b", "a2", and "c".
The operation terminal 20 having the terminal ID "a1" can give the management authority to at least one operation terminal 20 among the other three operation terminals 20 as the normal terminals.
Fig. 4 shows an example in which the operation terminal 20 having the terminal ID "a1" gives the management authority to the operation terminal 20 having the terminal ID "c".
When the operation terminal 20 having the terminal ID "a1" gives the management authority to the operation terminal 20 having the terminal ID "c", the user a executes the application program stored in the operation terminal 20 having the terminal ID "a 1". When the user a operates the operation unit 24 in accordance with the screen displayed on the display unit 23 by the execution of the application program, the control unit 21 generates a change instruction to change the account information including the terminal ID "c". The change instruction is an instruction to change the information indicating that the terminal is a normal terminal included in the account information including the terminal ID "c" to the information indicating that the terminal is a management terminal.
The communication unit 25 transmits a signal including the change instruction generated by the control unit 21 to the air conditioner 10 via the network 30.
The communication unit 121 of the air conditioner 10 receives a signal including a change instruction transmitted from the operation terminal 20. The control unit 13 acquires a change instruction included in the signal received by the communication unit 121, and stores the terminal ID included in the signal in the storage unit 15 according to the change instruction
The information indicating that the account information of "c" is changed to the information indicating that the terminal is a management terminal.
In this way, the management authority is given to the operation terminal 20 having the terminal ID "c" as a normal terminal. Thus, the number of management terminals increases in the air conditioning system 100, and the possibility of the state in which the setting, change, and release of the restriction setting cannot be performed can be reduced.
[ transfer of administrative Authority 1]
In the present embodiment, in addition to giving the management authority, the transfer of the management authority is performed. Next, referring to fig. 3 and 5, the transfer of management authority will be described. Fig. 5 is a diagram showing an example of transfer of management authority from the management terminal shown in fig. 3 to a normal terminal. In fig. 3 and 5, the management terminal having the management authority is indicated by an asterisk.
In the case where a plurality of operation terminals 20 including one management terminal are registered in one account (user a) shown in fig. 3, when communication between the management terminal and the air conditioner 10 is cut off or when the management terminal disappears from the management account, the management authority is transferred to one of the operation terminals 20 other than the management terminal registered in the management account.
For example, when the management terminal cannot transmit or receive information to or from the air conditioner 10, the control unit 13 of the air conditioner 10 determines that the management terminal and the air conditioner 10 are disconnected from each other.
When determining that the communication between the management terminal and the air conditioner 10 is cut off, the control unit 13 searches whether or not another operation terminal 20 is registered in the management account.
Specifically, the control unit 13 determines whether or not another account information (account information A2) including the user ID "a" included in the account information (account information A1) having the terminal ID "A1" is stored in the storage unit 15.
In the example of fig. 3, the storage unit 15 stores the user ID
Because the account information A2 is "a", the control unit 13 specifies the account information A2 and transfers the management authority to the operation terminal 20 having the terminal ID "A2", which is included in the account information A2. Specifically, the control unit 13 changes the information indicating that the terminal is a normal terminal included in the account information A2 to the information indicating that the terminal is a management terminal.
For example, in addition to the account information A2, there are a plurality of users having user IDs
When "a" includes account information indicating information of a normal terminal, the control unit 13 transfers the management authority to the operation terminal 20 corresponding to the account information including the terminal ID of the operation terminal 20 registered earliest among the plurality of pieces of account information.
The control unit 13 is not limited to the operation terminal 20 registered earliest among the plurality of pieces of account information, and may select any one of the operation terminals.
When the management terminal disappears from the account, the control unit 13 performs the same processing as that in the case where it is determined that the communication between the management terminal and the air conditioner 10 is disconnected.
For example, when the management authority is assigned, the control unit 13 notifies the operation terminal 20 (terminal ID "a 2") that the management authority is assigned to the new management terminal. Specifically, the control unit 13 generates information indicating that the management authority has been assigned. The communication unit 121 transmits a signal including the information generated by the control unit 13 to the operation terminal 20 (terminal ID) via the network 30
“a2”)。
The communication unit 25 of the operation terminal 20 (terminal ID "a 2") receives a signal transmitted from the air conditioner 10. The control unit 21 acquires information included in the signal received by the communication unit 25, and displays a message indicating that the management authority has been transferred, for example, on the display unit 23.
The user recognizes that the operation terminal 20 (terminal ID "a 2") is a management terminal by looking at the message displayed on the display unit 23.
In this way, by adopting a configuration in which the management authority is transferred to the account in which the plurality of operation terminals 20 are registered, it is possible to prevent a state in which the management terminal is absent.
[ transfer of administrative Authority 2]
Next, referring to fig. 5 and 6, the transfer of management authority when an operation terminal capable of transferring management authority is not registered in a management account will be described. Fig. 6 is a diagram showing an example of transfer of management authority from the management terminal shown in fig. 5 to a normal terminal. In fig. 5 and 6, the management terminal having the management authority is indicated by an asterisk.
As shown in fig. 5, in the case where a management account (user a) including one management terminal (terminal ID "a 2") and a plurality of accounts other than the management account (user B and user C) are registered, when communication between the management terminal and the air conditioner 10 is cut off, or when the management terminal disappears from the management account, or when the management account is deleted, the management authority is transferred to the operation terminal 20 registered in any account other than the management account.
Specifically, for example, as in the case of fig. 3, the control unit 13 of the air conditioner 10 determines that the communication between the management terminal and the air conditioner 10 is interrupted, and searches for an account other than the management account if the other operation terminal 20 is not registered in the management account as a result of searching whether or not the other operation terminal 20 is registered in the management account.
In the example of fig. 5, the storage unit 15 stores the user ID
Since the account information of "B" (referred to as account information B1) and the account information having the user ID "C" (referred to as account information C1), the control unit 13 designates the account information B1 or the account information C1 and transfers the management authority to the operation terminal 20 having the terminal ID included in any one of the account information.
For example, the control unit 13 transfers the management authority to the operation terminal 20 corresponding to the account information B1 registered earliest of the account information B1 and the account information C1.
The control unit 113 may assign the management authority to the operation terminal 20 corresponding to the account information C1 registered later among the account information B1 and the account information C1.
In this way, when the management authority cannot be assigned to another operation terminal in the management account, the configuration of assigning the management authority to the operation terminal 20 of another account can prevent the absence of the management terminal.
When the management terminal disappears from the account or when the management account is deleted, the control unit 13 performs the same processing as that in the case where it is determined that the communication between the management terminal and the air conditioner 10 is interrupted.
[ invalidation of restriction setting ]
Next, with reference to fig. 6 and 7, a process when there is no operation terminal capable of assigning management authority will be described. Fig. 7 is a diagram showing an example in which the management authority cannot be transferred from the management terminal shown in fig. 6 to a normal terminal.
Fig. 7 shows the following states: the management terminal (terminal ID "b") shown in fig. 6 is cut off from communication with the air conditioner 10; or the management terminal disappears from the management account; alternatively, when the management account is deleted, the communication between the normal terminal (terminal ID "C") and the air conditioner 10 is cut off, or the normal terminal (terminal ID "C") disappears from the account (account information C1) and the operation terminal 20 is not registered in the account, or the account (account information C1) is deleted.
In this case, the control section 13 cannot find the operation terminal 20 to which the management authority can be assigned. If the control unit 13 cannot find the operation terminal 20 to which the management authority can be assigned, the control unit invalidates the restriction setting set by the air conditioning unit 11 via the management terminal.
In this way, when there is no operation terminal 20 to which the management authority can be assigned, by invalidating the restriction setting, it is possible to prevent a state in which the air conditioner 10 cannot be operated by the operation terminal 20.
Air conditioning system including management device
Next, the air conditioning system 101 of the present embodiment will be described with reference to fig. 8 and 9. Fig. 8 is a diagram showing another example of the air conditioning system according to the present embodiment. Fig. 9 is a block diagram showing another example of the air conditioning system of the present embodiment. The air conditioning system 101 includes an air conditioner 10 having the air conditioning system 100 and an operation terminal 20, and further includes a management device 40.
The management device 40 is, for example, a room RM, a server installed in a place remote from the room RM, a desktop computer, a notebook computer, or the like. The management device 40 includes a control unit 41 and a storage unit 42. The control section 41 includes a processor such as a CPU. The storage unit 42 includes a storage device, and stores data and computer programs. The hardware configuration of the storage section 42 includes a main storage device such as a semiconductor memory and an auxiliary storage device such as a semiconductor memory, a solid state disk, and/or a hard disk drive. The storage section 42 may also contain removable media.
The management apparatus 40 is capable of two-way communication with one or more operation terminals 20. In addition, the management device 40 can perform bidirectional communication with the air conditioner 10. The management device 40 manages the air conditioner 10 and the operation terminal 20. Specifically, the control unit 41 relays information transmitted and received between the air conditioner 10 and the operation terminal 20.
The storage section 42 stores account information and the like in place of the storage section 15. Specifically, the control unit 41 receives signals including account information transmitted from the plurality of operation terminals 20. The control unit 41 stores the account information included in the received signal in the storage unit 42. The plurality of pieces of account information stored in the storage unit 42 are also referred to as authority information. The authority information indicates correspondence between a plurality of operation terminals 20 and management authority.
The storage unit 42 stores setting information indicating the contents of the restriction setting set by the management terminal. Specifically, upon receiving a signal including a restriction setting instruction transmitted from the management terminal, the control unit 41 acquires the restriction setting instruction, and stores the restriction setting indicating the restriction setting instruction as setting information in the storage unit 42.
[ control when communication between a management device and an air conditioner is interrupted ]
When the communication between the management device 40 and the air conditioner 10 is interrupted for a predetermined period or longer due to abnormality of at least one of the management device 40 and the air conditioner 10 or due to the communication function of the air conditioner 10 being turned OFF (OFF) in a state where the communication between the management device 40 and the air conditioner 10 is possible, the restriction setting set for the air conditioner 10 is invalidated.
For example, when the management device 40 cannot transmit and receive information, the control unit 13 of the air conditioner 10 determines that the management device 40 and the air conditioner 10 are disconnected from each other.
When determining that the communication between the management device 40 and the air conditioner 10 is interrupted, the control unit 13 starts the measurement of the time. When the measurement time exceeds the predetermined period, the control unit 13 invalidates the restriction setting set for the air conditioner 10.
Further, when the power supply of the air conditioner 10 is cut off while the control unit 13 is performing the measurement of time, the measurement of time by the control unit 13 is interrupted. After that, when the power of the air conditioner 10 is turned on, the control unit 13 restarts the time measurement from the time when the time measurement was interrupted.
In the present embodiment, when the management device 40 and the air conditioner 10 are restored to communication after the restriction setting is invalidated, the control unit 13 determines whether or not to validate the restriction setting.
For example, when information can be transmitted and received again with the management device 40, the control unit 13 determines that the communication between the management device 40 and the air conditioner 10 has been restored.
When determining that the communication between the management device 40 and the air conditioner 10 has been restored, the control unit 13 restores the restriction setting set for the air conditioner 10 before the communication is cut off. Specifically, the control unit 13 acquires setting information indicating the restriction setting set for the air-conditioning apparatus 10 before the communication is disconnected from the management device 40.
For example, the control unit 13 transmits a signal including a setting request requesting transmission of the corresponding setting information to the management device 40. Upon receiving the signal including the setting request, the control unit 41 of the management device 40 determines whether or not the limitation setting of the air conditioner 10 to which the setting request is transmitted is enabled based on the authority information of the storage unit 42.
Specifically, the control unit 41 refers to the authorization information and the setting information in the storage unit 42, and specifies and acquires the setting information corresponding to the air conditioner 10 to which the setting request is transmitted.
The control unit 41 validates the restriction setting of the air conditioner 10 based on the acquired setting information. Specifically, the control unit 41 transmits a signal including the acquired setting information to the air conditioner 10 as the transmission destination of the setting request.
The control unit 13 of the air conditioner 10 receives a signal including the setting information from the management device 40, and acquires the setting information. The control unit 13 controls the air conditioning unit 11 based on the acquired restriction setting.
