Embodiment 1 FIG.
FIG. 1 is a diagram schematically showing a device control system according to Embodiment 1 of the present invention. The device control system includes a controlled device 1, a router 3, a home operation terminal 4, a server 5, and an operation terminal 7. The server 5 is connected to the router 3 and the operation terminal 7 via the network 6, and the home management device 2 is connected to the router 3. In the following description, the controlled device 1 is abbreviated as “device 1”, the operation terminal 7 as “terminal 7”, and the home management device 2 as “management device 2” unless otherwise specified.

  The device 1 is a home appliance such as an air conditioner, a refrigerator, or a television. Information output from the device 1 includes model information for specifying the model of the device 1, operating state information indicating the operating state and operating mode of the device 1, a model name and a serial number for specifying the device 1, and the like. Identification information. Hereinafter, unless otherwise specified, these pieces of information are referred to as controlled device information. The device 1 includes a wireless communication unit 1 a and performs communication between the home operation terminal 4 and the management device 2. Note that the model of the device 1 is not limited to an air conditioner, a refrigerator, and a television, and any device may be used as long as it is a home appliance that can be remotely operated.

  The terminal 7 is a terminal capable of controlling the device 1, and may be a dedicated control terminal for controlling the device 1, or application software for executing a function for controlling the device 1 may be applied to a mobile phone, a tablet terminal, a smartphone, or the like. You may make it use as a control terminal by mounting. The terminal 7 can access a communication network compliant with communication standards such as 3G, 4G, and LTE, and a public wireless communication network (network 6) such as the Internet, and can control the device 1 via the server 5 and the router 3. .

  The terminal 7 is configured to be able to select two types of communication modes. For example, when the router 3 is a wireless LAN router, the communication mode is within a range (for example, a radio wave reach of the router 3 to which the management device 2 is connected). It is a communication mode (home mode) when in the home. The other communication mode is a communication mode (out-of-home mode) when the radio wave of the router 3 to which the management device 2 is connected does not reach. The mode switching of the terminal 7 is such that the home mode is automatically selected when the radio wave of the router 3 (the router 3 to which the management apparatus 2 is connected) registered in the terminal 7 reaches in advance, and the radio wave of the router 3 arrives. When not in range, the out-of-home mode is automatically selected. The terminal 7 switched to the home mode communicates with the device 1 via the router 3 and the management device 2 without going through the server 5, and the terminal 7 switched to the outside mode is the server 5, the router 3, and Communication with the device 1 is performed via the management device 2. When the terminal 7 controls (monitors and operates) the device 1 with the wireless LAN communication function is called home operation, and when the terminal 7 controls the device 1 with the Internet communication function is called outside operation.

  The in-home operation terminal 4 is a terminal such as a smartphone or a tablet that can control the device 1, similarly to the terminal 7. In the device control system, the operation from the in-home operation terminal 4 is prioritized over the operation from the terminal 7 outside the home. Further, since the home operation terminal 4 can preferentially reflect the operation even when the operation right is given to the terminal 7, the device 1 can be set from the home operation terminal 4 even if the terminal 7 or the network 6 breaks down. is there. The home operation terminal 4 includes a wireless communication unit 4 a and performs communication between the device 1 and the management device 2. Note that the terminal 7 can communicate over a long distance using the network 6 even when wireless LAN communication is not possible with the router 3 (for example, a wireless LAN router). Regardless, there is an advantage that communication is possible.

  The management device 2 controls one or a plurality of devices 1 based on the control data transmitted from the server 5. The control data transmitted from the server 5 includes data indicating that the control is performed by the terminal 7 existing outside the house. This data may be generated by the server 5 or may be generated by the management device 2. The management device 2 manages controlled device information from the device 1, and the controlled device information includes the controlled device information of the device 1 changed by the setting operation of the terminal 7 outside the home and the in-home operation in the home. And controlled device information of the device 1 changed at the terminal 4. The management device 2 accesses the device 1 at a constant cycle to request transmission of controlled device information, stores the controlled device information from the device 1, and stores the database server 5 at a constant communication cycle (for example, every 5 minutes). -2 is accessed and the stored controlled device information is uploaded.

  Furthermore, the management device 2 downloads the setting information stored in the specific area in the database server 5-2 and transmits it to the device 1. By downloading the setting information, the terminal 7 outside the home can indirectly operate the device 1 via the server 5. In order to access the device 1 via the network 6, it is necessary to have a dedicated communication path (IP address). In general, the contract with the provider is one contract, and a communication system that monitors and operates the device 1 without changing the Internet contract in use is desirable in order to reduce the cost for the dedicated route. Therefore, the device control system of the present embodiment is configured such that the terminal 7 and the management device 2 transmit information via the server 5.

  The management device 2 has a function of mutually converting the communication method of the device 1 and the communication method of the router 3. For example, the controlled device information transmitted from the device 1 using the unique communication method of the device 1 is converted into communication data conforming to the LAN 8 communication method and transmitted to the router 3. In addition, the setting information transmitted from the router 3 is converted into communication data conforming to the communication method of the device 1 and transmitted to the device 1.

  Communication between the management device 2, the device 1, and the home operation terminal 4 is performed by the wireless communication units 1a, 2a, and 4a, and communication between the device 1 and the home operation terminal 4 is performed by the wireless communication units 1a and 4a. Is called. Examples of wireless signals used in the wireless communication units 1a, 2a, and 4a include signals conforming to an IEEE802.11 series wireless LAN communication system such as Wi-Fi (registered trademark), Bluetooth (registered trademark), or 900 MHz band. Specific low power communication can be used. However, it is not always necessary to comply with these standards, and wireless communication conforming to other communication methods may be used.

  The server 5 includes a Web server 5-1 to which the terminal 7 is connected and a database server 5-2 that stores data processed by the Web server 5-1. The unique area in the database server 5-2 is assigned to each device 1, and the terminal 7 can access only the unique area of the device 1 registered in advance. In addition to acquiring controlled device information in a specific area in the database server 5-2 by accessing the server 5, the terminal 7 is given the operation right when changing the setting of the device 1. Accesses the server 5 and changes the setting of the specific area in the database server 5-2 from the terminal 7.

  FIG. 2 is a diagram for explaining a communication operation of the device control system according to the embodiment of the present invention. The management device 2 uploads device information (controlled device information) along with its own MAC (Media Access Control) address and serial number to the server 5 (path N1), and also manages its own data (in the database server 5-2 ( (Setting data managed by MAC address and serial number) is downloaded (path N2). When the setting data is changed, the device 1 changes the setting based on the setting data.

  On the other hand, when the terminal 7 is switched to the out-of-home mode, the setting information of the terminal 7 is transmitted to the server 5 via the network 6 (route a). The server 5 that has received the setting information is given an operation right for the terminal 7 and the operation right is registered. The operation right of the terminal 7 is generated from the timing when the operation right is registered. Also, controlled device information from the device 1 is transmitted to the terminal 7 via the router 3 and the server 5, and for example, the operation state (operation mode, wind direction, etc.) of the device 1 is displayed on the terminal 7 that has received the controlled device information. Is done. Even when the setting change of the device 1 is performed at the home operation terminal 4, the controlled device information is transmitted to the terminal 7, so that the user of the terminal 7 can check the latest operation state of the device 1.

  FIG. 3 is a flowchart of the communication interruption monitoring operation by the home management apparatus 2 according to Embodiment 1 of the present invention. The management device 2 transmits data (controlled device information) to the server 5 by regular communication with the server 5 (step S1). If there is a reception response from the server 5 for the transmitted data (step S2, Yes), the management device 2 determines that communication with the server 5 is normal, and communication between the server 5 and the management device 2 The communication status information indicating the status is updated to “communication status = normal” (step S3).

  In step S2, when there is no reception response from the server 5 for the transmitted data (step S2, No), the management device 2 determines that communication with the server 5 has been interrupted, and sets the communication status information as “communication”. Update to “state = disruption” (step S4).

  The management device 2 notifies the updated operation status information to the home operation terminal 4 via the wireless communication unit 2a (step S5). In the flowchart of FIG. 3, it is described that the communication status information is notified from the management device 2 to the home operation terminal 4 at the timing when the communication status information is updated in the management device 2. May be configured to update the communication state information at a timing when an inquiry from the home operation terminal 4 is received, and to respond to the home operation terminal 4 with the updated latest communication state information.

  Thereafter, the management device 2 waits for a certain time (for example, 5 minutes) (step S6), and then monitors the communication state with the server 5 by performing the data transmission operation of step S1 again. Thereby, it becomes possible to update the communication status information between the server 5 and the management apparatus 2 periodically. The fixed time is not limited to 5 minutes.

  FIG. 4 is a diagram illustrating a display screen example of a notice of stoppage of the device 1 due to communication interruption. FIG. 4 shows an example of the operation screen 4-1 and the stop notice display 4-1 a displayed on the liquid crystal display unit of the home operation terminal 4. FIG. 4 shows an example in which the device 1 to be operated is an air conditioner.

  Information transmitted from the management device 2 to the home operation terminal 4 includes, in addition to the communication status information, whether the most recent operation of the device 1 is a terminal 7 outside the home or the home operation terminal 4 inside the home. The final control source information shown is also transmitted. When the final control source information transmitted from the management device 2 is “outside” indicating that the terminal 7 outside the home is operated and the communication status information is “disruption”, the in-home operation terminal 4 It is determined that communication during an external operation is interrupted (communication is interrupted). Then, the timer count is started from the time when it is determined that the communication is interrupted, and changes to “in-home” indicating that the final control source is operated by the home operation terminal 4 in the home before the timer count passes the first time. If the communication status information does not change to “communication status = normal”, the fact that the first time has elapsed since the communication interruption is displayed (see the stop notice display 4-1a). At this time, if the communication interruption state continues until the second time elapses, a pop-up may be displayed indicating that the air conditioner (air conditioner) is automatically stopped, a method for avoiding the automatic stop, or the like. .

  In addition, you may comprise so that these display information may be notified to a user using audio | voice alerting | reporting means, such as a speaker incorporated in the in-home operation terminal 4.

  When the communication interruption state continues from the time when the first time has elapsed since the time when the first time has elapsed since the time when the communication was interrupted until the second time has elapsed, the air conditioner (air conditioner) is automatically stopped (stop warning display) 4-1a) and a method for avoiding automatic stop are displayed in a pop-up. FIG. 4 shows a display example when the first time is 10 hours and the second time is 12 hours as an example. The user who has seen the stop notice display 4-1a can avoid the automatic stop of the air conditioner due to the continuation of the communication interruption state by operating the device 1 with the home operation terminal 4 or the like.

  FIG. 5 is a flowchart of a communication interruption warning display operation in the home operation terminal 4. Based on the final control source information received from the management device 2, the home operation terminal 4 determines whether the final control source is outside the home or in the home. If the determination result is home (step S11, No), the home operation terminal 4 repeats the process of step S11. If the determination result is outside the home (step S11, Yes), the home operation terminal 4 determines whether the communication is interrupted or the communication is normal based on the communication state information received from the management device 2. When the determination result is a normal communication state (step S12, No), the process returns to step S11, and when the communication is interrupted (step S12, Yes), the in-home operation terminal 4 measures the duration of the communication interruption state. Timer count is started (step S13).

  When the final count is changed to the home (step S14, Yes) or the communication state is restored (step S16, Yes) until the timer count passes the first time (step S17, No), the home operation terminal 4 clears the timer (step S15) and returns to step S11. That is, even when the final control source does not change to the home before the timer count has passed the first time (step S14, No), when the communication is restored (step S16, Yes), the home operation terminal 4 The timer is cleared (step S15), and the process returns to step S11.

  If the communication is not restored (No at Step S16) and the timer count has passed the first time (Yes at Step S17), the in-home operation terminal 4 indicates that the first time has passed since the communication was interrupted (accordingly) If this state continues as it is, a message indicating that the device 1 is automatically stopped and an avoidance method) are displayed (step S18).

  From the time when the first time has elapsed since the communication interruption was displayed until the second time passed (No in step S21), the final control source changed to home (step S19, Yes) or communication was restored. When it does (step S20, Yes), the home operation terminal 4 clears the timer (step S15), and returns to step S11.

  Even if the final control source does not change to the home (step S19, No), the communication is not restored (step S20, No), and the timer count has passed the second time (step S21, Yes), the home operation The terminal 4 transmits a stop operation signal to the device 1 via the management device 2 (step S22).
