Description

  The present invention relates to a remote operation system and an electronic device for remotely operating an electronic device using a communication terminal device.

  There are technologies for remotely operating home appliances (home electronic devices) and confirming the operating state remotely using a communication terminal device such as a mobile phone or a smartphone via a communication network. In such a technique, a plurality of users constituting a family remotely operate one home appliance using each communication terminal device (for example, Patent Document 1). In addition, using a communication terminal device instead of a remote controller (remote controller), home appliances are operated.

  By the way, in remote operation using a remote controller, operation instructions that are later in time series are generally given priority. On the other hand, in remote operation using a communication terminal device that can identify the user who performed the operation, there is a method of giving priority between users and giving priority to the operation instruction of the user with high priority. That is, when applied to a family, the parent operation instruction is given priority over the child operation instruction.

  On the other hand, there is a conventional technique that prohibits or restricts the use of home appliances by children. Child lock function, parental control function, etc. The child lock function is mounted on a heater, a kettle pot, etc., and is a function for invalidating the operation. The parental control function is installed in TVs, personal computers, communication terminal devices, and the like, and is a function that restricts functions that can be used depending on age.

Japanese Patent Laying-Open No. 2006-140691 (released on June 1, 2006)

  However, in a mechanism in which a plurality of users remotely operate one device (home appliance) using each communication terminal device as in the above-described prior art, a user operation with a high priority is performed according to the priority given between users. If the instruction is simply prioritized, there is a problem that the convenience of the user with low priority may be significantly impaired.

  This is the case, for example, when a parent who is a high-priority user goes out while operating an air conditioner using a communication terminal device at home. In this case, an operation instruction such as driving switching from a child who is a low-priority user is not reflected until the parent cancels driving.

  However, even in such a case, the operation can be switched using the remote controller by setting the remote operation by the remote controller to be prioritized over the remote operation by the communication terminal device. However, as communication terminal devices become widespread, it is conceivable that communication terminal devices will replace remote controls in the future, and it is necessary to propose a mechanism that does not rely on remote controls.

  The parental control function that restricts use by children restricts the functions that can be used depending on the age, so it is effective for home appliances for viewing information, but it does not work well when used for home appliances such as air conditioners. . For home appliances such as air conditioners, a mechanism that allows a user with a low priority to use it under the control of a user with a high priority is suitable.

  The present invention has been made in view of such a problem, and the object thereof is to provide a high-priority user operation instruction in a mechanism in which a plurality of users remotely operate one device using each communication terminal device. It is an object of the present invention to provide an electronic device and a remote control system that can improve the convenience of a low-priority user while giving priority to the user.

  A remote operation system according to an aspect of the present invention is a remote operation system in which a plurality of users remotely operate an electronic device from a communication terminal device via a communication network, and the electronic device is remotely operated between the plurality of users. A setting unit for setting a priority when performing the operation, and an operation control for operating the electronic device in accordance with the priority, giving priority to an operation instruction from a user with high priority over an operation instruction from a user with low priority And a notification unit for notifying the content of the operation to the communication terminal device of the user with high priority when an operation is instructed by the user with low priority.

  According to the remote operation system of one aspect of the present invention, in a mechanism in which a plurality of users remotely operate one electronic device using each communication terminal device, priority is given to an operation instruction from a user with high priority. There is an effect that the convenience of the user with low priority can be improved.

[Embodiment 1]
Hereinafter, it will be as follows if one Embodiment of this invention is described based on FIGS. In the present embodiment, an air conditioner (air conditioner) is illustrated as a remotely operated home appliance.

(Configuration of remote operation system 100)
FIG. 1 is a diagram showing a schematic configuration of a remote operation system 100 according to the present embodiment. As shown in FIG. 1, in the remote operation system 100, an air conditioner 10 (10-1, 10-2, 10-3, 10-4) that is a home appliance (electronic device) installed in a user home 50, and a cloud A server (server device) 20 and a communication terminal device 30 (30-1, 30-2, 30-3) are connected via a wide area communication network 62.

  The air conditioner 10 is a so-called network home appliance that is connected to the wide-area communication network 62 and can be controlled via the wide-area communication network 62. In the present embodiment, the home appliance adapter 5 (5-1, 5-2, 5-3, 5-, which has a communication function part that enables remote operation to the air conditioner 10 that does not have a connection function to the wide area communication network 62. By connecting 4), it is a network home appliance. By making the communication function part enabling remote operation optional as an external configuration, the common home appliance adapter 5 can be applied to air conditioners 10 of different model numbers and home appliances other than the air conditioner 10, and costs can be reduced. Of course, the structure (structure integrated with the air conditioner 10 and the household appliance adapter 5) by which the communication function part was previously integrated in the air conditioner 10 may be sufficient.

  The cloud server 20 associates the communication terminal device 30 with the home appliance adapter 5 and registers and manages the combination. By registering the combination in the cloud server 20, the communication terminal device 30 can remotely operate the air conditioner 10 connected to the associated home appliance adapter 5 via the cloud server 20. Information regarding the air conditioner 10 connected to the associated home appliance adapter 5 is transmitted to the communication terminal device 30 via the cloud server 20. Hereinafter, operating the air conditioner 10 connected to the associated home appliance adapter 5 will be described as simply operating the air conditioner 10 remotely.

  A single communication terminal device 30 can be associated with a plurality of such air-conditioners 10 to be remotely operated. In addition, a plurality of communication terminal devices 30 can be associated as remote operation sources of the air conditioner 10 for one home appliance adapter 5. Examples of the communication terminal device 30 include a smartphone or a tablet terminal in which an application for remote operation is downloaded.

  On the other hand, the user home 50 is provided with a wireless local area network (LAN) that is a narrow area communication network. The wireless LAN relay station 40 is connected to a wide area communication network 62 including the Internet. The relay station 40 is a communication device such as a WiFi (registered trademark) router or a WiFi (registered trademark) access point. In the present embodiment, a configuration including the Internet is exemplified as the wide area communication network 62, but a telephone line network, a mobile communication network, a CATV (CAble TeleVision) communication network, a satellite communication network, or the like can also be used.

  The cloud server 20 and the home appliance adapter 5 installed in the user's home 50 can communicate via the wide area communication network 62 and the wireless LAN relay station 40. Further, the cloud server 20 and the communication terminal device 30 can communicate with each other via the wide area communication network 62. The communication terminal device 30 and the Internet in the wide area communication network 62 are connected using 3G (3rd Generation), LTE (Long Term Evolution), a home or public WiFi (registered trademark) access point, and the like. The home appliance adapter 5 and the communication terminal device 30 are both wireless communication devices and can communicate with each other via the relay station 40 without using the wide area communication network 62.

  In FIG. 1, four air conditioners 10-1 to 10-4, three communication terminal devices 30-1 to 30-3, and three user homes 50 are illustrated as examples. Not too much.

(Configuration of cloud server 20)
FIG. 2 is a block diagram illustrating a schematic configuration of the cloud server 20 in the remote operation system 100. The cloud server 20 is a server that manages each air conditioner 10 provided in each user home 50, and includes a control unit 21, a storage unit 22, and a communication unit 23 as illustrated in FIG.

  For example, the control unit 21 includes a computer device including an arithmetic processing unit such as a CPU (Central Processing Unit) or a dedicated processor, and controls the operation of each unit of the cloud server 20. The storage unit 22 stores various information (data) used in the cloud server 20. The communication unit 23 performs mutual communication with the home appliance adapter 5 and the communication terminal device 30 via the wide area communication network 62.

  The control unit 21 includes an association management unit 21a, a priority setting unit (setting unit) 21b, an operation control unit 21c, and an operation content notification unit (notification unit) 21d.

  The association management unit 21a manages the association between the communication terminal device 30 and the home appliance adapter 5 that can be remotely operated. The storage unit 22 stores a correspondence table of the communication terminal device 30 and the home appliance adapter 5 that is created and used by the association management unit 21a. In addition, the structure which matches a user and the household appliance adapter 5 directly may be sufficient.

  The priority setting unit 21 b sets a priority among the plurality of communication terminal devices 30 associated with one home appliance adapter 5. The storage unit 22 stores a correspondence table (hereinafter, priority table) 22a between the communication terminal device 30 and the priority as shown in FIG. Such a priority table 22 a is provided for each home appliance adapter 5.

  In the example illustrated in FIG. 3A, the user ID of the user who owns the communication terminal device 30 is used for identifying the communication terminal device 30. A communication terminal apparatus 30 that is assigned a priority “1” to the communication terminal apparatus 30 possessed by the user with the user ID “0001” and the user ID “0002” and possessed by the user with the user ID “0003” and the user ID “0004”. The priority “2” is set at 30. Here, the priority increases as the number decreases.

  In the example shown in FIG. 3B, the cloud ID set by the cloud server 20 in association with the unique information such as the address information and UUID of the communication terminal device 30 is used for identifying the communication terminal device 30. Yes. The priority “1” is set for the communication terminal device 30 with the cloud ID “smartphone_1”, the priority “3” is set for the communication terminal device 30 with the cloud ID “smartphone_2”, and the cloud ID “smartphone_3”. The priority “2” is set for the communication terminal device 30. In addition, the priority table 22a should just be able to specify the priority order between the some communication terminal devices 30 matched with each household appliance adapter 5. FIG.

  In the present embodiment, since the association management unit 21 a manages the communication terminal device 30 and the home appliance adapter 5 in association with each other, the priority is set between the communication terminal devices 30. However, in short, it is only necessary that a priority is set between a plurality of users associated with one home appliance adapter 5.

  When the operation control unit 21 c receives an operation instruction for the air conditioner 10 from the communication terminal device 30, the operation control unit 21 c causes the home appliance adapter 5 connected to the operation target air conditioner 10 to drive the air conditioner 10 according to the content of the received operation instruction. Send a command. Although details will be described later, when the home appliance adapter 5 receives the control command, the home appliance adapter 5 transmits the control command to the air conditioner 10, and the air conditioner 10 operates according to the received control command. The storage unit 22 also stores a correspondence table between operation instructions and control commands.

  In addition, when operating the air conditioner 10, the operation control unit 21 c sends an operation instruction from the communication terminal device 30 with a high priority according to the priority set by the priority setting unit 21 b from the communication terminal device 30 with a low priority. Prioritize operation instructions.

  For example, when the priority table 22a shown in FIG. 3A is provided, priority is given in a state where the air conditioner 10 is operated by an operation instruction from the communication terminal device 30 with the user ID “0001” having the priority “1”. Even if an operation instruction is received from the communication terminal device 30 with the user ID “0003” of the degree “2”, it is invalidated. The same applies when an operation instruction is received from the communication terminal device 30 with the user ID “0004” having the priority “2”. On the other hand, in a state in which the air conditioner 10 is operated by an operation instruction from the communication terminal device 30 with the user ID “0003” with the priority “2”, the communication terminal device 30 with the user ID “0001” with the priority “1”. When an operation instruction is received, the air conditioner 10 is operated with the instructed operation content. The same applies when an operation instruction is received from the communication terminal device 30 with the user ID “0002” having the priority “1”.

  In this way, by giving priority to an operation instruction from the communication terminal device 30 with a high priority, a change instructed by a user (a user with a high priority, such as a parent) possessing the communication terminal device 30 with a high priority. It is not preferable that an operation that is not desirable to be performed (for example, an eco-driving mode when power is tight) is arbitrarily changed by a user (a user with a low priority, for example, a child) possessing the communication terminal device 30 with a low priority. Invitation of the situation can be avoided.

  In the present embodiment, when the priorities of the communication terminal device 30 that has instructed the operation first and the communication terminal device 30 that has instructed the operation are the same, the operation control unit 21c determines the subsequent operation instruction in time series. It is the structure which gives priority to. However, on the contrary, the prior operation instruction may be prioritized, or the prioritized one (rear or earlier) may be switched depending on the operation content.

  When an operation is instructed from the communication terminal device 30 with a low priority, the operation content notification unit 21d notifies the communication terminal device 30 with a high priority of the operation content. For example, when the priority table shown in FIG. 3A is provided, when an operation is instructed from the communication terminal device 30 with the user ID “0003” with the priority “2”, the user ID “1” with the user ID “0003”. The instructed operation content is notified to each communication terminal device 30 of “0001” and user ID “0002”. When there are a plurality of high-priority communication terminal devices 30, the operation content may be notified to all of them, or only the communication terminal device 30 with the highest priority may be notified, or predetermined. Only one device may be notified. When the situation where the air conditioner 10 is used by a plurality of family members is applied, the owner of the communication terminal device 30 that receives the notification of the operation content is a mother or father who manages the operation of the air conditioner 10 in the home. Moreover, the user of the communication terminal device 30 with a low priority to which the operation content is notified is a child or the like.

  In this way, the operation content instructed from the communication terminal device 30 with a low priority is notified to the communication terminal device 30 with a high priority, and the user possessing the communication terminal device 30 with a high priority (high priority) By allowing the user to check, if there is no problem in the notified operation content (for example, an operation for increasing the temperature during cooling or an operation for decreasing the temperature during heating), For example, by canceling the operation performed earlier, the operation instructed by the low priority user can be reflected. Thereby, while giving priority to the operation instruction from the user with high priority, the convenience of the user with low priority can be improved.

  In the present embodiment, the operation content notification unit 21d uses a specific communication terminal device 30 having a predetermined high priority as a notification destination of the operation content, and an operation from the specific communication terminal device 30. In the state where the air conditioner 10 is operated according to the instruction, the notification is made only when an operation is instructed from the communication terminal device 30 having a low priority. That is, when the situation where the air conditioner 10 is used by a plurality of family members is applied, the child himself / herself only when the mother remotely operates the air conditioner 10 using his / her own communication terminal device 30 (specific communication terminal device). The operation content instructed from the communication terminal device 30 is notified to the mother's communication terminal device 30.

  When a configuration is such that each time an operation instruction is issued from the communication terminal device 30 with a low priority, the content is notified to the communication terminal device 30 with a high priority, a user who owns the communication terminal device 30 with a high priority May feel annoying. However, as described above, only when the air conditioner 10 is operated using the communication terminal device 30 with high priority, the operation content by the user with low priority is notified, so that the priority is high. The user who owns the communication terminal device 30 can be prevented from feeling annoying.

  In addition, in the present embodiment, the operation content notification unit 21d is configured to make an inquiry as to whether or not the operation (operation instructed by a communication terminal device with a low priority) can be performed, along with the notification of the operation content. ing. And the operation control part 21c will operate the air conditioner 10 by the operation instruction by the communication terminal device 30 with low priority, if the notification which permits execution of operation is received from the communication terminal device 30 with high priority. Specifically, the operation control unit 21c transmits to the home appliance adapter 5 a control command for driving the air conditioner 10 according to the content of the operation instruction received from the communication terminal device 30 having a low priority.

  As described above, it is necessary to permit a user with a high priority to determine whether or not the operation instructed from the communication terminal device 30 with a low priority can be executed on the side of the communication terminal device 30 with a high priority. However, the air conditioner 10 can be operated relatively freely by a low-priority user. Thereby, while giving priority to the operation instruction from the user with high priority, the convenience of the user with low priority can be further improved.

  In the following, it is assumed that each user performs remote operation of the air conditioner 10 using his / her own communication terminal device 30 to which priority is set. The remote control of the air conditioner 10 using 30 is simply expressed as a remote operation (operation instruction) by a user with high priority, and the user with low priority controls the air conditioner 10 using the communication terminal device 30 with low priority. Remote operation is simply expressed as a remote operation (operation instruction) by a low-priority user.

(Configuration of communication terminal apparatus 30)
FIG. 4 is a block diagram illustrating a schematic configuration of the communication terminal device 30 in the remote operation system 100. As illustrated in FIG. 4, the communication terminal device 30 includes a control unit 31, a storage unit 32, a display unit 33, a communication unit 34, and an operation unit 35.

  For example, the control unit 31 includes a computer device including an arithmetic processing unit such as a CPU (Central Processing Unit) or a dedicated processor, and controls the operation of each unit of the communication terminal device 30. The storage unit 32 stores various information (data) used in the communication terminal device 30. The display unit 33 displays various information to be presented to the user. The communication unit 34 performs communication via the wide area communication network 62 and mutual communication between devices via the wireless LAN relay station 40.

  Further, the control unit 31 is constructed with a remote operation unit 31 a for remotely operating the air conditioner 10. The remote operation unit 31 a is constructed by a dedicated application downloaded to the communication terminal device 30. The remote operation unit 31 a displays an operation screen as shown in FIG. 5 on the display unit 33 and accepts a remote operation for the air conditioner 10. When the “send with this content” button is pressed, a control command for commanding execution of the operation instruction received on the operation screen is transmitted from the communication terminal device 30 to the cloud server 20.

  Further, when the operation content is notified from the cloud server 20, the remote operation unit 31 a notifies the user of the communication terminal device 30 of the existence of information to be confirmed by including it in the new arrival information reception list. For example, as shown in FIG. 6, at the top of the home screen in the communication terminal device 30 or in the center of the home screen in the communication terminal device 30 as shown in FIG. A message notifying operation details such as “.” Is displayed. Mr. XX is a low-priority user who instructs the operation.

  Here, when a user with a high priority taps (selects) the display part of the message, the remote control unit 31a displays the first screen such as a login screen, and “XX's heating operation is displayed on the screen. A pop-up button for determining whether or not to allow an operation instruction (in this case, heating operation) by a low-priority user is displayed together with a message such as “Requesting? 7).

  In addition, when the operation content is notified from the cloud server 20 while the operation screen is activated, the remote operation unit 31a permits the operation instruction along with the message on the operation screen as illustrated in FIG. Pop up a button to decide whether or not.

  Here, when a user with high priority taps (operates) the “Yes” button, a notification (permitted / not permitted result) notifying permission is transmitted from the communication terminal device 30 to the cloud server 20. On the other hand, when the “No” button is tapped (operated), a notification (approval result) notifying disapproval is transmitted from the communication terminal device 30 to the cloud server 20.

(Configuration of home appliance adapter 5 and air conditioner 10)
The home appliance adapter 5 is a device that enables the air conditioner 10 to perform network communication. The home appliance adapter 5 receives various data including operation signals (commands) from the cloud server 20. Data received from the cloud server 20 includes data from the communication terminal device 30 transmitted via the cloud server 20 in addition to data from the cloud server 20 itself. The data received from the cloud server 20 may be for controlling the home appliance adapter 5 itself, or may be transmitted to the air conditioner 10 via the home appliance adapter 5 to control the air conditioner 10. Furthermore, the home appliance adapter 5 transmits information about the air conditioner 10 transmitted from the air conditioner 10 to the cloud server 20.

  FIG. 9 is a block diagram illustrating a schematic configuration of the home appliance adapter 5 and the air conditioner 10 in the remote operation system 100. The home appliance adapter 5 includes a control unit 41, a storage unit 42, a communication unit 43, and a connection unit 44.

  The control part 41 consists of computer apparatuses comprised by arithmetic processing parts, such as CPU (Central Processing Unit) and a dedicated processor, for example, and controls operation | movement of each part of the household appliance adapter 5. FIG. When the data received from the cloud server 20 is a control command for controlling the air conditioner 10, for example, a control command for commanding the operation of the air conditioner, the control unit 41 transmits this to the air conditioner 10. The storage unit 42 stores various information used by the home appliance adapter 5. The communication unit 43 performs mutual communication with the cloud server 20 via the wide area communication network 62. The connection unit 44 communicates with the connection unit 15 of the air conditioner 10. The connection between the connection unit 44 and the connection unit 15 of the air conditioner 10 may be, for example, a connection using a USB (Universal Serial Bus) connector.

  The air conditioner 10 is an apparatus that performs an air conditioning operation, and includes a control unit 11, a storage unit 13, a driving operation unit 14, a connection unit 15, a communication unit 16, and an environment detection unit 17, as shown in FIG. The control unit 11 controls the operation of each unit of the air conditioner 10. The control part 11 consists of computer apparatuses comprised by arithmetic processing parts, such as CPU (Central Processing Unit) and a dedicated processor, for example, and controls operation | movement of each part of the air-conditioner 10. FIG. A control command from the cloud server 20 is input to the control unit 11 via the home appliance adapter 5, and a control command from the remote controller 19 is input via the communication unit 16. The control unit 11 operates the driving operation unit 14 in accordance with the received control command. The storage unit 13 stores various information used in the air conditioner 10. The connection unit 15 performs mutual communication with the connection unit 44 of the home appliance adapter 5.

  The driving operation unit 14 executes various driving operations of the air conditioner 10 under the control of the control unit 11.

The environment detection unit 17 may be configured to detect one of temperature and humidity. Moreover, the environment detection part 17 may be provided with the structure which can detect about the environmental conditions of the user house 50 other than temperature and humidity.

  The communication unit 16 receives an operation instruction by short-range communication using infrared rays using the remote controller 19. The operation instruction received by the communication unit 16 is sent to the control unit 11, and various driving operations are executed under the control of the control unit 11. In this embodiment, the communication is performed using infrared rays. However, the communication may be performed using wireless or wired communication that can perform other short-range communication.

(Processing flow in remote operation)
Processing of each device in the remote operation system 100 will be described using a specific example of FIG. FIG. 10 shows a state in which the air-conditioner 10-1 is remotely operated (operation instruction a) by a high-priority user α using a high-priority communication terminal device 30-1 (hereinafter, communication terminal device A) This is a case where the low-priority user β performs a remote operation (operation instruction b) on the communication terminal device 30-2 (hereinafter, communication terminal device B) having a low priority.

  When the user α having a high priority instructs the air conditioner 10 to perform the operation a by remote operation using the communication terminal device A, the operation instruction a is transmitted from the communication terminal device A to the cloud server 20 (S1). This is received (S2). The cloud server 20 transmits the received operation instruction a to the home appliance adapter 5-1 connected to the air conditioner 10-1 (S3).

  When home appliance adapter 5-1 receives operation instruction a from cloud server 20 (S4), it transmits this to air conditioner 10-1 (S5). When the air conditioner 10-1 receives the operation instruction a from the home appliance adapter 5-1 (S6), the air conditioner 10-1 performs an operation corresponding to the operation instruction a (S7).

  Thus, in a state where the air conditioner 10-1 is remotely operated by the user α with high priority, the user β with low priority operates the air conditioner 10-1 remotely using the communication terminal device B and operates b. Is sent from the communication terminal device B to the cloud server 20 (S11).

  When the cloud server 20 receives the operation instruction b (S12), since the air conditioner 10-1 is already remotely operated by the communication terminal device A, the priority of the communication terminal device A and the communication terminal device B is set. The determination is made with reference to the priority table 22a (see FIG. 3) (S13). In this example, since the priority of the communication terminal device B is lower than the priority of the communication terminal device A, the cloud server 20 operates the operation instruction b from the communication terminal device B to the communication terminal device A having a higher priority. The contents are notified and an inquiry is made as to whether or not the operation can be executed (S14).

  When receiving the operation content of the operation instruction b from the cloud server 20 (S15), the communication terminal device A notifies the user α that there is a notification to be confirmed. After that, when the user α performs an operation for confirming the information, it is displayed that the user β requests a change to the operation instruction b (S16). In the present embodiment, an availability button for determining whether or not to permit change to the operation instruction b is also displayed. When the user α operates the availability button to determine the availability result, the communication terminal device A transmits the availability result to the cloud server 20 (S17).

  The cloud server 20 receives the availability result from the communication terminal device A (S18), and if possible, transmits the operation instruction b to the home appliance adapter 5-1 connected to the air conditioner 10-1 (S19). When home appliance adapter 5-1 receives operation instruction b from cloud server 20 (S20), it transmits this to air conditioner 10-1 (S21). When the air conditioner 10-1 receives the operation instruction b from the home appliance adapter 5-1 (S22), the air conditioner 10-1 performs an operation corresponding to the operation instruction b (S23). On the other hand, if it is impossible in S18, the cloud server 20 does not transmit the operation instruction b to the home appliance adapter 5-1.

  Although different from this example, when the user β has a higher priority than the user α (the communication terminal device B has a higher priority than the communication terminal device A), the cloud server 20 The received operation instruction b is transmitted to the home appliance adapter 5-1 connected to the air conditioner 10-1 without notifying the terminal device A of the operation content of the operation instruction b.

  As described above, in the remote operation system 100 according to the present embodiment, the operation control unit 21c gives priority to an operation instruction from a user with a high priority over an operation instruction from a user with a low priority, and an operation content notification unit. 21d is a configuration for notifying the communication terminal device 30 of the user with high priority of the operation content instructed by the user with low priority.

  As a result, for the operation desired by the low-priority user, the high-priority user confirms the operation content, and if there is no problem, cancels the operation that the user has instructed first. While giving priority to the operation instruction, the operation instruction desired by the low priority user can be reflected in the air conditioner 10.

  In addition, since the operation content instructed by the low-priority user is notified only when the high-priority user is remotely operating, the high-priority user does not feel bothered. it can.

  Further, a configuration in which a user with a high priority is inquired about whether or not an operation instructed by a user with a low priority can be executed, and when the execution of the operation is permitted, the air conditioner 10 is operated by an operation instruction by a user with a low priority. It is said. Therefore, although permission by a user with high priority is necessary, a user with low priority can operate the air conditioner 10 relatively freely.

  As described above, according to the remote operation system 100 of the present embodiment, in a mechanism in which a plurality of users remotely operate one air conditioner 10 using each communication terminal device 30, an operation instruction from a user with high priority is given. It is possible to improve the convenience of the low priority user.

[Embodiment 2]
The remote operation system 101 according to the present embodiment (see FIG. 1) and the remote operation system 100 according to the first embodiment have different timings when the air conditioner 10 executes an operation instruction from a user with low priority. In the remote operation system 100 of the first embodiment, an operation instruction from a user with low priority is reflected for the first time when the user with high priority permits it. On the other hand, in the remote operation system 101 according to the present embodiment, the operation instruction from the low priority user is reflected without waiting for the permission by the high priority user, and the high priority user does not permit it. In this case, the operation is canceled to return to the previous operation state.

  Processing of each device in the remote operation system 101 will be described using a specific example of FIG. In FIG. 11, as in FIG. 10, the air conditioner 10-1 is remotely operated (operation instruction “a”) by the user α with high priority by the communication terminal device 30-1 (hereinafter, communication terminal device A) with high priority. When a low-priority user β (low-priority user) performs a remote operation (operation instruction b) on the low-priority communication terminal device 30-2 (hereinafter, communication terminal device B). It is.

  When the user α having high priority remotely operates the air conditioner 10-1 using the communication terminal device A to instruct the operation a (S1), the air conditioner 10-1 is subjected to the same processing as S2 to S6 in FIG. An operation corresponding to the operation instruction a is executed (S7).

  Thus, in a state where the air conditioner 10-1 is remotely operated by the user α with high priority, the user β with low priority operates the air conditioner 10-1 remotely using the communication terminal device B and operates b. Is sent from the communication terminal device B to the cloud server 20 (S11), and the cloud server 20 receives it (S12).

  When the cloud server 20 receives the operation instruction b, the cloud server 20 transmits the operation instruction b to the home appliance adapter 5-1 connected to the air conditioner 10-1 (S41). Thereby, the household appliance adapter 5 receives the operation instruction b from the cloud server 20 (S20), and performs the operation | movement corresponding to the operation instruction b through the process similar to S21-S22 of FIG. 10 (S23).

  In addition, since the cloud server 20 is in a state where the air conditioner 10-1 has already been remotely operated by the communication terminal device A, the cloud server 20 performs the same processing as S13 to S18 in FIG. Inquires whether the specified operation can be executed. If the availability result received from the communication terminal device A is acceptable, the cloud server 20 has already transmitted the operation instruction b, and therefore transmits nothing to the home appliance adapter 5-1. On the other hand, if it is not possible, a cancel instruction for canceling the previous operation instruction (operation instruction b) is transmitted to the home appliance adapter 5-1 (S42).

  When home appliance adapter 5-1 receives a cancellation instruction from cloud server 20 (S43), it transmits this to air conditioner 10-1 (S44). When the air conditioner 10-1 receives a cancel instruction from the home appliance adapter 5-1 (S45), the operation corresponding to the previous operation instruction (operation instruction b) being executed is changed to the original operation (operation of the operation instruction a). Return (S46).

  In the remote operation system 101 according to the present embodiment, a change to an operation instructed by a user with low priority is executed without waiting for permission from the user with high priority. For this reason, the remote operation unit 31a gives a message such as “A heating operation is being requested by Mr. XXX. Do you approve?” As shown in FIG. A pop-up is displayed with a button for determining whether or not to approve the operation changed in (heating operation in this case).

  According to such a configuration, since the operation instruction from the low-priority user is reflected on the air conditioner 10 for a period until the answer to the inquiry is received from the high-priority user, the convenience of the low-priority user The property can be further improved.

[Embodiment 3]
In the remote operation system 102 (see FIG. 1) of the present embodiment, in the remote operation system 100 of the first embodiment, an answer deadline (expiration date) is set for an inquiry to a user with a high priority. When the time limit is reached before reception, a function for operating the air conditioner 10 according to an operation instruction from a user with low priority is added, as in the case where the result of availability is acceptable.

  Processing of each device in the remote operation system 102 will be described using a specific example of FIG. In FIG. 13, as in FIG. 10, the air-conditioner 10-1 is remotely operated (operation instruction “a”) by the user α with high priority using the communication terminal device 30-1 (hereinafter referred to as communication terminal device A). In this state, a low-priority user β performs a remote operation (operation instruction b) on the low-priority communication terminal device 30-2 (hereinafter, communication terminal device B).

  In FIG. 13, S50 is added. In S50, when the cloud server 20 notifies the operation content of the operation instruction b by the communication terminal device B to the communication terminal device A having a high priority, the cloud server 20 reaches the response deadline without receiving the result of the availability in S18. An operation instruction b is transmitted to the home appliance adapter 5-1.

  According to the above configuration, even when a user with high priority is not aware of an inquiry such as putting the communication terminal device A in a bag, the air conditioner 10-1 has a low priority when the answer deadline has passed. Since the operation according to the operation instruction from the user is executed, the convenience of the user with low priority can be further improved.

  In this way, even in the case where an answer from a user with high priority (acceptability result) is not received, the remote operation unit 31a is configured to execute an operation according to an operation instruction from a user with low priority. As an operation content notification, a message such as “Mr. XX requests heating operation. Do you want to reject it?” As shown in FIG. 14 is an operation instruction (in this case, heating operation) by a low-priority user. It is preferable to display a pop-up with a button for rejecting the change due to.

  In other words, with this way of inquiring, unless a user with a high priority presses the “reject” button and clearly indicates the intention of prohibiting the change, an operation instruction from a user with a low priority is executed. As a result, the convenience of users with low priority can be further improved.

  Moreover, the structure which provides such a reply time limit can also be combined with the structure which reflects the operation instruction of the user with a low priority of Embodiment 2 for the time being. In that case, although not shown in the figure, a message such as “It is heating operation at the request of Mr. XX. Do you want to reject it and return it to the base?” Pops up with a button of “Reject”. In such a configuration, unless the “reject” button is pressed, an operation instruction (in this case, heating operation) by a low-priority user continues to be reflected from the time when the instruction is given, thereby further improving the convenience of the low-priority user. Can be improved.
