Detailed Description
[ first embodiment ]
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, a washing machine is exemplified as an electric device to which the present invention is applied, but the present invention is not limited to this and may be applied to electric devices other than a washing machine.
Fig. 1 is a schematic configuration diagram of a cloud connection system (hereinafter, referred to as the present system) including a washing machine 100 according to the first embodiment. The system includes, in addition to the washing machine 100 which is usually installed indoors, an outdoor cloud server (hereinafter, referred to as a server) 200 which communicates with the washing machine 100, a mobile terminal (for example, a smartphone) 300 which communicates with the server 200, and an access point 400 which centrally facilitates communication between the washing machine 100 and the server 200.
The washing machine 100 and the access point 400 are connected by communication via a wireless LAN (first line), and the washing machine 100 communicates with the server 200 via the access point 400. More specifically, the washing machine 100 transmits information to the server 200 via the access point 400 or receives information from the server 200, for example, using a communication standard of Wi-Fi (registered trademark). In the present system, it is necessary to perform connection setting in advance in order to connect the washing machine 100 and the access point 400 by wireless LAN. Generally, methods for setting a connection to a wireless LAN include known methods such as a method of using a button connection of a router such as WPS (Wi-Fi Protected Setup) and a method of directly inputting an SSID (service set identifier) and a password of the router to an electric device. Further, communication between the server 200 and the access point 400 is performed, for example, via the internet.
The mobile terminal 300 is a device registered in the server 200 so as to be bound to the washing machine 100, and is capable of receiving information related to the washing machine 100 from the server 200 and changing the setting of the washing machine 100. In addition, the portable terminal 300 in the present system has a bluetooth (registered trademark) communication function, and can directly communicate with the washing machine 100 using bluetooth (second line). The mobile terminal 300 of the present system is previously installed with a predetermined application program corresponding to the present system in order to perform a predetermined operation to be described later.
The washing machine 100 has an operation display part 110 and a communication part 120 shown in fig. 1. The communication unit 120 has a wireless LAN communication function for performing communication with the access point 400 and a bluetooth communication function for performing communication with the portable terminal 300. Here, the washing machine 100 includes one communication unit 120, and the communication unit 120 has a wireless LAN communication function and a bluetooth communication function. That is, the communication unit 120 includes the first communication means and the second communication means described in the claims. However, the present invention is not limited to this, and the washing machine 100 may include two communication units, one having a first communication means for performing wireless LAN communication with the access point 400, and the other having a second communication means for performing bluetooth communication with the portable terminal 300. In addition, the wireless LAN communication preferably uses Wi-Fi communication, and the Bluetooth communication preferably uses BLE (Bluetooth Low Energy) communication.
When a user attempts to acquire information about the washing machine 100 from the portable terminal 300, generally, the washing machine 100 accesses the server 200 via the access point 400 and transmits the information from the server 200 to the portable terminal 300. That is, the washing machine 100 can communicate with the portable terminal 300 through the wireless LAN and the access point 400 connected to the wireless LAN. However, when the wireless LAN communication is abnormal, such as when the radio wave condition of the wireless LAN is weak, the router cannot transmit information to the mobile terminal 300.
Therefore, when the communication of the wireless LAN is abnormal, the washing machine 100 of the present system switches the communication function of the communication unit 120 from the wireless LAN communication to the bluetooth communication, and transmits information (communication abnormality notification information) notifying the communication abnormality to the portable terminal 300. That is, if the portable terminal 300 is within the communication range of bluetooth, it is able to directly receive notification of communication abnormality from the washing machine 100.
At this time, the communication abnormality notification information transmitted from the washing machine 100 includes the cause of the communication abnormality, and the portable terminal 300 that has received the communication abnormality notification information displays the cause on a screen or the like to notify the user of the cause. Thereby, the user can know the cause of the communication abnormality in the washing machine 100. The portable terminal 300 may also display a method of handling the communication abnormality (including transmission in the communication abnormality notification information). For example, when a communication abnormality occurs in the wireless LAN, the mobile terminal 300 may display a message such as "please turn on the power supply of the router again because communication with the router is disabled". This makes it easy to eliminate communication abnormality of the wireless LAN by the user.
In addition, a situation where the portable terminal 300 cannot acquire information on the washing machine 100 may occur when the server 200 is busy and the washing machine 100 cannot access the server 200, in addition to communication abnormality of the wireless LAN. In this case, the washing machine 100 can switch the communication function of the communication unit 120 from the wireless LAN communication to the bluetooth communication, and can transmit the communication abnormality notification information to the portable terminal 300. In this case, the mobile terminal 300 can display a message such as "the server is busy, please wait a little" or the like.
When the washing machine 100 transmits the communication abnormality notification information through bluetooth communication, the intensity of the electric wave of the communication abnormality notification information is preferably weakened before the connection between the washing machine 100 and the portable terminal 300 is established and strengthened after the connection is established. This prevents the communication error notification information from being received by the mobile terminal 300 located at a remote location (for example, in another house nearby), and thus improves the safety of the washing machine 100.
In the first embodiment, when a communication abnormality occurs in the wireless LAN, only the function that can be performed using bluetooth communication with the portable terminal 300 is enabled. That is, functions that the washing machine 100 and the portable terminal 300 can perform (smartphone cooperation function), such as state notification of the washing machine 100 (notification of washing end time, etc.), can be performed by bluetooth communication between the washing machine 100 and the portable terminal 300. On the other hand, the function to be executed by the washing machine 100 in cooperation with the server 200 (the server cooperation function, the function to be executed by downloading data from the server 200, the function to be executed by receiving an instruction from the server 200, and the like) is stopped. As described above, when communication is abnormal, the smartphone cooperation function is enabled and the server cooperation function is disabled, so that the functions of the washing machine 100 can be stably provided.
[ second embodiment ]
In the second embodiment, it is assumed that the mobile terminal 300 having received the communication abnormality notification information can transmit data to the server 200 via the internet.
The portable terminal 300 may directly access the server 200 from the internet without via the access point 400. That is, even when a communication abnormality of the wireless LAN occurs and the washing machine 100 cannot be connected to the server 200 via the access point 400, the mobile terminal 300 can be connected to the server 200.
Therefore, instead of the access point 400, the portable terminal 300 can provide a cloud service based on a server cooperation function even when communication of the wireless LAN is abnormal by intermediately facilitating connection of the washing machine 100 and the server 200.
[ third embodiment ]
In the first and second embodiments described above, the washing machine 100 at home or the like has been described with respect to an example of use of bluetooth communication when a communication abnormality of a wireless LAN occurs. In the third embodiment, another use example of bluetooth communication, specifically, a use example in a place where there is no wireless LAN environment will be described.
Fig. 2 is a schematic configuration diagram showing a connection state with the mobile terminal 300 when the washing machine 100 according to the third embodiment is operated in the demo mode. In addition, the demo mode is a mode for allowing a user (consumer) to simulate an experience of a service (cloud service) based on a cloud connection with the server 200 in the washing machine 100 provided in a shop for sale.
As described in the first embodiment, in order to use the cloud service in the washing machine 100 on the user's portable terminal 300, the connection setting of the wireless LAN is made between the washing machine 100 and the access point 400, and the portable terminal 300 needs to be bound with the washing machine 100 and registered in the server 200. However, there is no wireless LAN environment in the store, and the user's portable terminal 300 is not bound to the washing machine 100 and registered.
Therefore, in the demonstration of the washing machine 100, the communication unit 120 of the washing machine 100 operating in the demonstration mode outputs the connection beacon through bluetooth, and the mobile terminal 300 of the user connected to the connection beacon experiences the demonstration of the cloud service. That is, the mobile terminal 300 having received the connection beacon is caused to display a screen presenting the presentation experience, and when the connection is made to the connection beacon in accordance with the screen display, the presentation experience can be performed. In this demonstration, the washing machine 100 transmits data such as a display screen for demonstration to the mobile terminal 300 and receives data of an operation instruction from the mobile terminal 300, thereby enabling the user to experience the same operation as that in the case of using the cloud service in a simulated manner.
In addition, the data transmitted from the washing machine 100 operating in the demo mode to the portable terminal 300 is data stored in advance in the memory of the washing machine 100 for demo, not data transmitted from the server 200. Accordingly, when the washing machine 100 operates in the demo mode, the cloud connection between the washing machine 100 and the server 200 may not be required, and the demo may be performed only through the bluetooth communication between the washing machine 100 and the portable terminal 300.
The connection beacon output from washing machine 100 preferably attenuates the radio wave intensity when portable terminal 300 is not connected, and enhances the radio wave intensity when portable terminal 300 is connected. Thus, only the user who is close to the washing machine 100 provided for demonstration may be prompted for the demonstration experience. After the mobile terminal 300 is connected to the connection beacon, the stability of the communication connection can be improved.
In addition, in this demonstration, since binding registration between the portable terminal 300 and the washing machine 100 is not required, a plurality of portable terminals 300 can be simultaneously connected to one washing machine 100 as shown in fig. 1. In this case, the portable terminal 300 (for example, the portable terminal 300-1) that is initially connected to the connection beacon may be given an operation right to execute the presentation. While the portable terminal 300-1 is executing the demo, the washing machine 100 transmits data for the demo to the portable terminal 300-1, but the data is transmitted so as to be receivable by other portable terminals 300 (for example, the portable terminals 300-2 and 300-3). Therefore, the portable terminals 300-2, 300-3 can simultaneously see the demonstration being executed by the portable terminal 300-1 (without the operation right, the demonstration cannot be executed).
In addition, the portable terminal 300 for experience demonstration can receive sound data from the washing machine 100 and emit sound. When the washing machine 100 uses an actual cloud service, which is not a demonstration, the washing machine 100 may receive sound data from the server 200 and emit a sound. However, if the washing machine 100 makes a sound even during the demonstration of the store, the user may have difficulty hearing the sound due to surrounding noise or the like. Therefore, if the portable terminal 300 makes a sound instead of the washing machine 100 during the demonstration in the shop, the user can easily hear the sound for the demonstration.
[ embodiment 4]
In the first to third embodiments, the description has been given of the function (bluetooth information transmission function) of the washing machine 100 for transmitting information to the portable terminal 300 of the user using bluetooth communication when the wireless LAN cannot be used.
The bluetooth information transmission function may be a function that can be arbitrarily turned on/off by the user in the washing machine 100. That is, the safety of the washing machine 100 can be improved by turning off the bluetooth information transmission function when the user does not particularly need it.
As described above, the electric device according to the first aspect of the present embodiment is an electric device that communicates with a mobile terminal, and is characterized in that: the mobile terminal device includes a first communication unit that communicates with the mobile terminal via a first line and an access point connected to the first line, and a second communication unit that directly communicates with the mobile terminal via a second line, and when communication with the mobile terminal is not possible by the first communication unit, communication with the mobile terminal is performed by the second communication unit.
In addition, the electric device may be configured to transmit, by the second communication unit, communication abnormality notification information regarding an abnormality in communication using the first communication unit.
According to the above configuration, the second communication means transmits the communication abnormality notification information, so that the mobile terminal such as a smartphone held by the user can receive the communication abnormality notification information and notify the user of the communication abnormality of the first line.
The electrical device may be configured such that the communication abnormality notification information includes a method of eliminating the communication abnormality.
According to the above configuration, the user who receives the communication abnormality notification information by the smartphone or the like can take measures to eliminate the communication abnormality.
In addition, the electric device may be configured to enable a function (smartphone cooperation function) using only the second communication means and disable a function (server cooperation function) using the first communication means when a communication abnormality occurs in the first communication means.
According to the above configuration, when communication is abnormal, the smartphone cooperation function is enabled and the server cooperation function is disabled, thereby stably providing the function of the washing machine.
The electric device may be configured to transmit data to a server communicable with the electric device via the access point via the portable terminal that receives the normal abnormality notification information.
According to the above configuration, the mobile terminal can provide a service based on a server cooperation function even when the communication of the first line is abnormal by intermediately facilitating the connection between the electrical device and the server communicable with the electrical device via the access point.
In the above-described electric device, the electric wave intensity of the communication abnormality notification information may be configured to be decreased before the connection between the electric device and the portable terminal that receives the communication abnormality notification information is established, and to be increased after the connection is established.
According to the above configuration, before the connection between the portable terminal of the user and the electric device is established, it is possible to prevent the communication abnormality notification information from being received by another portable terminal located at a distant position (for example, another house adjacent thereto). After the connection between the user's portable terminal and the electric device is established, reliable connection can be ensured by enhancing the intensity of the electric wave.
Further, an electrical device according to a second aspect of the present embodiment is an electrical device for communicating with a mobile terminal, the electrical device including: the mobile terminal device is provided with a first communication means for communicating with the mobile terminal via a first line and an access point connected to the first line, and a second communication means for directly communicating with the mobile terminal via a second line, and has a presentation mode capable of simulating an experience cloud service by communicating with another mobile terminal via the second communication means, the cloud service being based on a cloud connection with a server communicable with the electric device via the access point.
With the above configuration, in a shop or the like where there is no first line (for example, in a wireless LAN environment), it is possible to execute a presentation of the simulated experience cloud service by communicating with the mobile terminal using the second communication means.
In the above-described electric device, the electric wave intensity during operation in the demonstration mode may be reduced before the connection with the portable terminal is established, and may be increased after the connection is established.
According to the above configuration, only the user who is close to the electric device provided for the presentation is presented with the presentation experience. After the portable terminal is connected to the electric equipment, the electric wave intensity can be enhanced, and the stability of communication connection is improved.
In the above-described electric device, the plurality of mobile terminals may be connected to the electric device when the electric device is operated in the demonstration mode, and the electric device may be configured to cause the first connected mobile terminal to execute the demonstration and to display a demonstration screen executed at that time on the later connected mobile terminal.
According to the above configuration, a plurality of users can simultaneously perform a presentation experience.
In addition, the electric device may be configured to cause the portable terminal to emit a sound emitted from the electric device when an actual cloud service is performed while the electric device is operating in the demo mode.
According to the above configuration, even when a user performs a presentation in a shop with a lot of ambient noise, the user can easily hear the sound for the presentation.
The electric device may be configured to be turned on/off arbitrarily using the function of the second communication unit.
According to the above configuration, when the user does not particularly need it, the safety of the electric device can be improved by turning off the function using the second communication means.
