Description

  The present invention relates to a remote operation system capable of operating an electronic device from a communication terminal such as a tablet terminal or a smartphone via a communication network such as the Internet in addition to a dedicated remote controller (dedicated operation device).

  In recent years, various electronic devices (operation target devices) are remotely operated via a communication network using a communication terminal such as a smartphone, a tablet, or a mobile phone (for example, see Patent Document 1). In the case of remote operation using such a communication terminal, it is necessary to perform processing for registering mutual identification information (for example, IP address) between the communication terminal and the electronic device. This process is called “pairing”. By performing pairing, identification information of the communication partner is registered in each of the communication terminal and the electronic device. This pairing process prevents the electronic device from accepting an operation signal from a device other than the paired communication terminal, so that no intentional operation by a third party is performed.

  In the pairing process, for example, the communication terminal is set to a pairing mode in which pairing is possible, and similarly, the identification information is exchanged between the communication terminal and the electronic device in a state where the electronic device is also set to the pairing mode Is done by.

JP 2002-345051 A (published on November 29, 2002)

  However, since the pairing operation as described above is generally performed in a state where each pairing device is directly operated and set to the pairing mode, the pairing devices are physically separated from each other. If it is present or in a position where it is difficult to reach the user's hand, the pairing workability is particularly poor. Furthermore, since it is difficult for the user to confirm whether the process is actually executed, there is a problem that the operability is poor. Further, in a remote operation system using a communication terminal, there is a demand for preventing unintended remote operation from a communication terminal and enhancing security.

  Accordingly, the present invention has been made in view of the above problems, and provides a remote operation system with improved operability in processing (pairing) for registering a combination between a communication terminal and an electronic device and with enhanced security. There is to do.

  In order to solve the above problems, a remote operation system according to one aspect of the present invention includes an electronic device and a communication terminal connected to a communication network, and a dedicated operation device that exclusively operates the electronic device remotely. In the remote operation system, the dedicated controller has a storage unit for storing the identification information of the electronic device, causes the communication terminal to register the identification information of the electronic device, and identifies the communication terminal from the communication terminal. Registration means for acquiring information and registering it in the electronic device, wherein the communication terminal supplies its identification information together with operation information indicating an operation on the electronic device to the electronic device identified by the registered identification information. An operation control means for transmitting, and the electronic device receives identification information matching the identification information of the registered communication terminal together with operation information indicating an operation on the electronic device. When, an operation acceptance means for accepting an operation indicating the operation information received, and characterized in that.

  According to the above remote operation system, the dedicated operation device is used to remotely operate the electronic device and is used at the user's hand. Therefore, the dedicated operation device and the communication terminal are operated at the user's hand (or nearby). Thus, the pairing process can be performed. Further, when the dedicated controller and the communication terminal have a display screen for displaying / instructing the flow of the pairing process, the user can also perform pairing while confirming this. As described above, by using the dedicated operation device, the operability of pairing between the electronic device and the communication terminal can be improved.

  In addition, most dedicated operating devices that exclusively operate electronic devices are shipped as accessories of the electronic devices. Therefore, it can be said that the dedicated operation device is easy to be obtained by the user of the electronic device, and the dedicated operation device is difficult to reach the hands of a third party. In the remote operation system, since the identification information of the electronic device cannot be acquired unless the dedicated operation device is used, it is possible to prevent pairing between the third party communication terminal and the electronic device that cannot obtain the dedicated operation device. It is possible to strengthen the system security.

(Remote controller)
The remote controller 2 is an operating device that exclusively controls the home appliance 1 remotely. In this embodiment, it shall ship as an accessory of the household appliance 1. FIG. In the present embodiment, the remote controller 2 operates the home appliance 1 by infrared communication, and remotely operates the home appliance 1 by infrared communication without going through the communication network 4.

  In the present embodiment, the remote controller 2 is dedicated to the home appliance 1 (attached from the time of shipment), but may be configured by an application or the like on a smartphone or a tablet terminal. Further, the operation of the home appliance 1 from the remote controller 2 is not limited to infrared communication, and may be, for example, short-range wireless communication or wired communication. Or the structure operated via the communication network 4 may be sufficient.

  When the remote controller 2 is realized using an application of a device such as a smartphone or a tablet terminal, the same device can also be used as the communication terminal 3 that communicates via the communication network 4.

  As shown in FIG. 1, the remote controller 2 includes a control unit 20, a display unit 21, an input unit 22, a storage unit 23, and an infrared communication unit 24.

  The control unit 20 is a block that controls the operation of each unit of the remote controller 2. The control unit 20 also functions as an authentication code generation unit (authentication information generation unit) 20a and a registration unit (registration unit) 20b. The authentication code generation unit 20 a generates an authentication code from the identification code of the home appliance 1 stored in the storage unit 23 described later and the identification code of the communication terminal 3 acquired from the communication terminal 3. The registration unit 20 b causes the communication terminal 3 to register the identification information of the home appliance 1 stored in the storage unit 23 described later, and causes the home appliance 1 to register the identification information of the communication terminal 3 acquired from the communication terminal 3. Further, the registration unit 20b causes the home appliance 1 and the communication terminal 3 to register the authentication code generated by the authentication code generation unit 20a.

  The input unit 22 is a block that receives an input from the user and transmits the input to the control unit 20. Note that the display unit 21 and the input unit 22 may be provided as a unitary structure, for example, as a touch panel.

  The storage unit 23 is a block that stores various information used by the remote controller 2. The storage unit 23 further stores an identification code of the home appliance 1. Since the remote controller 2 is shipped together with the home appliance 1, the identification code of the home appliance 1 may be stored in the storage unit 23 at the time of shipment.

  The infrared communication unit 24 is a block for the remote controller 2 to communicate with the outside by infrared communication.

(Communication terminal)
The communication terminal 3 is a communication device, and is provided so that the home appliance 1 can be operated via the communication network 4. The communication terminal 3 is assumed to be a general-purpose device such as a tablet terminal, a smartphone, or a personal computer in which software (application) for operating the home appliance 1 is built. In the remote operation system 100, it is possible to operate one home appliance 1 from a plurality of communication terminals 3. It is also possible to operate a plurality of home appliances 1 from one communication terminal 3. However, as will be described later, a communication terminal that has been paired with the home appliance 1 (described later) can be operated.

  As illustrated in FIG. 1, the communication terminal 3 includes a control unit 30, a display operation unit 31, a storage unit 32, and a communication unit 33.

  The control unit (operation control means) 30 is a block that controls the operation of each unit of the communication terminal 3. The control unit 30 supplies the network communication unit 33b to the home appliance 1 identified by the identification code of the home appliance 1 stored in the storage unit 32, which will be described later, along with the operation information indicating the operation on the home appliance 1. Control and send.

  The display operation unit 31 is a block that displays various information to be presented to the user and receives input from the user. The display operation unit 31 is provided as a touch panel, for example. The display unit and the operation unit may be provided separately.

  The storage unit 32 is a block that stores various types of information used in the communication terminal 3. Further, the storage unit 32 stores the (own) identification code of the communication terminal 3. When receiving the identification code and the authentication code of the home appliance 1 from the remote controller 2, they are stored.

  The communication unit 33 is a block for performing communication with the outside, and includes an infrared communication unit 33 a that performs infrared communication and a network communication unit 33 b that is connected to the communication network 4. In the present embodiment, since the remote controller 2 performs infrared communication, the infrared communication unit 33a is provided. However, depending on the communication mode of the remote controller 2, the remote controller 2 is not limited to the infrared communication unit 33a. What is necessary is just to provide the means which can communicate.

(Pairing and setting of preset conditions)
Next, the pairing process between the home appliance 1 and the communication terminal 3 and the setting process of the preset condition for the home appliance 1 will be described with reference to FIG.

  First, as shown in FIG. 2A, the remote controller 2 and the communication terminal 3 perform bidirectional communication. Communication may be started from either the remote controller 2 or the communication terminal 3. At this time, when a display screen displaying / instructing the flow of the pairing process is displayed on the display unit 21 of the remote controller 2 and the display operation unit 31 of the communication terminal 3, the user performs the pairing operation while confirming this. It can also be done and helps the operation.

  The remote controller 2 acquires the identification code of the communication terminal 3 from the communication terminal 3, and generates an authentication code from the identification code of the communication terminal 3 and the identification code of the home appliance 1. In addition, the remote controller 2 transmits the identification code of the home appliance 1 and the generated authentication code to the communication terminal 3. Further, the remote controller 2 acquires the preset condition from the communication terminal 3. In addition, as long as it is a condition that can be set by the remote controller 2 among the preset conditions, for example, conditions for time, temperature, and humidity, the setting may be received from the input unit 22 of the remote controller 2.

  On the other hand, the communication terminal 3 transmits the (own) identification code of the communication terminal 3 to the remote controller 2. Further, the communication terminal 3 receives the identification code of the home appliance 1 and the generated authentication code from the remote controller 2 and stores them in the storage unit 32. Further, the communication terminal 3 transmits a preset condition to the remote controller 2.

  The setting of the preset condition in the communication terminal 3 may be performed by receiving a user input from the display operation unit 31 of the communication terminal 3, or the application of the communication terminal 3 acquires the preset condition automatically or manually. It may be like this. For example, a specific base station can be set as the preset condition. As the specific base station, for example, a base station in a range where the user normally acts such as the user's home, commuting route, and work place can be cited.

  In the present embodiment, the authentication code generation unit 20a is described as being provided in the remote controller 2, but may be provided in the communication terminal 3. In this case, the communication terminal 3 receives the identification code of the home appliance 1 at the remote controller 2, generates an authentication code from the identification code of the home appliance 1 and the identification code of the communication terminal 3 stored in the storage unit 32, and Transmit to the controller 2.

  Next, as shown in FIG. 2B, the remote controller 2 transmits the identification code and authentication code of the communication terminal 3 and the preset condition to the home appliance 1. This transmission may be executed by a user operation, or the remote controller 2 and the home appliance 1 are configured to automatically communicate regularly and may be executed at that time. When the household appliance 1 receives the identification code and authentication code of the communication terminal 3 and the preset condition, the household appliance 1 stores them in the storage unit 11.

  When the process of registering the identification code of the home appliance 1 in the communication terminal 3 and registering the identification code of the communication terminal 3 in the home appliance 1, that is, when the pairing process is completed, as shown in FIG. The communication terminal 3 and the home appliance 1 can communicate bidirectionally via the communication network 4. When the home appliance 1 is remotely operated from the communication terminal 3, the identification code and the authentication code of the communication terminal 3 are transmitted from the communication terminal 3 to the home appliance 1 together with the operation information through the base station 5. At this time, information on the base station 5 is also notified to the home appliance 1. Therefore, the household appliance 1 can acquire information on the base station 5 (information on a position where the communication terminal 3 has transmitted the operation signal). The determination whether the home appliance 1 receives the received operation information will be described later. Information from the home appliance 1 (for example, information indicating the state of the home appliance 1 or information indicating whether or not an operation has been accepted) is transmitted (notified) to the communication terminal 3 via the communication network 4.

  As described above, in the remote operation system 100 of the present embodiment, the pairing process between the home appliance 1 and the communication terminal is performed via the remote controller 2. Since the remote controller 2 remotely controls the home appliance 1 and is used at the user's hand, the pairing process is performed by operating the remote controller 2 and the communication terminal 3 at the user's hand (or the vicinity). Can do. Thus, by using the remote controller 2, the operability of pairing between the home appliance 1 and the communication terminal 3 can be improved.

  Moreover, since the remote controller 2 is shipped as an accessory of the home appliance 1, it can be said that it is easy for the user of the home appliance 1 to obtain and difficult to reach the hands of a third party. In the remote operation system 100, since the identification code of the home appliance 1 cannot be obtained unless the remote controller 2 is used, it is possible to prevent pairing of the home appliance 1 with a third party communication terminal that cannot obtain the remote controller 2. It is possible to strengthen the system security. Note that when the remote controller 2 is shipped together with the home appliance 1, the identification code of the home appliance 1 may be stored in the storage unit 23 of the remote controller 2.

  In the remote operation system 100, the registration unit 20b registers the identification code and the authentication code by infrared communication. Therefore, the communication terminal 3 receives the identification code and the authentication code by infrared communication. On the other hand, the communication terminal 3 remotely operates the home appliance 1 via the communication network 4. Thus, by using different communication media for the pairing process and the remote operation, the leakage of the identification code and the authentication code can be suppressed, and the security can be further strengthened.

  Furthermore, infrared communication is a directional communication medium, and since communication cannot be performed in the vicinity, leakage of an identification code and an authentication code can be further prevented. In addition, since the remote controller 2 is provided with an infrared communication unit 24 for remotely controlling the home appliance 1, it can be used for pairing, so the remote operation system 100 can be used without cost. Can be configured.

(Remote operation processing)
Next, processing when the home appliance 1 is remotely operated from the communication terminal 3 in the remote operation system 100 will be described with reference to FIG.

  First, the communication terminal 3 outside the home transmits an operation signal (step S1, hereinafter abbreviated as S1). The operation signal includes an authentication code and an identification code of the communication terminal 3 together with operation information indicating an operation on the home appliance 1. The operation information, the authentication code, and the identification code of the communication terminal 3 may be transmitted separately. When only the identification code of the communication terminal 3 is registered in the home appliance 1, the communication terminal 3 may transmit the identification code of the communication terminal 3 together with the operation information as an operation signal.

  When the home appliance 1 receives the operation signal (S2), it is determined whether the received authentication code and the identification code of the communication terminal match the authentication code stored in the storage unit 11 and the identification code of the communication terminal 3, respectively ( S3). If they do not match (F in S3), the received operation information is invalidated, that is, no operation is accepted (S4). And the information which notifies that it is unauthorized operation is transmitted with respect to the communication terminal 3 which is the transmission source of the operation signal (S5). Moreover, you may notify the communication terminal 3 (appropriate communication terminal 3) registered into the household appliance 1 that there existed unauthorized operation | movement at this time.

  If the received authentication code and the identification code of the communication terminal match the authentication code stored in the storage unit 11 and the identification code of the communication terminal 3 (T in S3), the home appliance 1 matches the preset condition. It is determined whether information has been acquired (S6).

  Specifically, the preset conditions are the position at which the communication terminal 3 has transmitted the operation information, the time at which the communication terminal 3 has transmitted the operation signal, the time at which the home appliance 1 has received the operation information, and the home appliance 1 has received the operation signal. This is a condition related to the ambient temperature or humidity of the home appliance. Conditions other than these may be used. When the information that matches the preset condition is the information on the position where the communication terminal 3 has transmitted the operation information, the communication terminal 3 transmits the position information together with the operation information, for example, the information on the base station 5 at the time of transmission. The network communication unit 12b of the home appliance 1 obtains it by receiving it. When the information that matches the preset condition is information on the time when the communication terminal 3 transmits the operation information, the communication terminal 3 transmits the information on the operation information transmission time together with the operation information, and the network of the home appliance 1 Acquired by receiving the communication unit 12b. In addition, when the information that matches the preset condition is information on the time when the home appliance 1 receives the operation information, when the home appliance 1 receives the operation information, the clock unit 14 acquires the time information, and the home appliance 1 In the case of the temperature or humidity information around the home appliance when the operation information is received, the sensor unit 15 acquires the temperature or humidity information when the home appliance 1 receives the operation information.

  If information that matches the preset condition is not acquired or information that does not match is acquired (F in S6), the received operation information is invalidated, that is, the operation is not accepted (S7). And the information which notifies that it cannot operate is transmitted with respect to the communication terminal 3 which is the transmission source of the operation signal (S8).

  Regarding S6 and S7, for example, when the preset condition is time, it means that operation information received at a time that is not a preset time is not accepted. Further, when the preset condition is a position where the communication terminal 3 has transmitted the operation signal, for example, a specific base station that has not been transmitted from the preset position (for example, a range in which the user normally operates) That is, the operation information transmitted from other than the base station is not accepted. The operation information transmitted from other than the specific base station may be information (transmitted from a communication terminal of a third party other than the user), but does not accept the operation as described above, so the remote operation system 100 Can enhance security.

  If the preset condition is the time when the communication terminal 3 transmits the operation signal or the time when the home appliance 1 receives the operation information, the operation information transmitted or received at a time other than the preset time. This means that no operations will be accepted. Here, there is a high possibility that the user operates the home appliance 1 from the communication terminal 3 during a time zone outside the home, and a high possibility that the user operates the home appliance from the remote controller 2 during the time zone within the home. Therefore, if the time zone (time) in which the user is usually away from home, such as commuting and working hours, is set as the preset condition, the security of the remote operation system 100 can be enhanced. That is, the operation information transmitted from the communication terminal 3 at a time other than the preset time may be incorrect information (transmitted from a third party communication terminal other than the user). Since no operation is accepted, security can be enhanced.

  Further, when the preset condition is the temperature or humidity around the home appliance 1 when the home appliance 1 receives the operation information, the temperature or humidity at which the periphery of the home appliance 1 is preset when the home appliance 1 receives the operation information. If it is, it means that the operation information is not accepted.

  When information that matches the preset condition is acquired (T in S6), operation accepting unit 10a accepts the operation (S10), and home appliance 1 executes an operation corresponding to the operation.

  In the present embodiment, when a plurality of preset conditions are set, the process proceeds to S9 when all the conditions are met, and the process proceeds to S7 otherwise. For example, if two preset conditions are provided and the first condition is not met, the received operation information is invalidated without determining the second condition, and the operation signal is transmitted from the source. Information notifying that it is an unauthorized operation is transmitted to a certain communication terminal 3. If the first condition is met and the second condition is not met, the received operation information is invalidated, and the communication terminal 3 that is the source of the operation signal is notified that the operation cannot be performed. Send. This is particularly effective when the first condition is more important than the second condition in determining whether the transmission source is illegal or appropriate.

  By the above processing, the determination as to whether the operation signal is correct from the communication terminal 3 can be carried out by performing the determination under the preset condition in addition to the determination with the authentication code and the identification code. If information that matches the preset condition is not acquired or information that does not match is acquired, the operation can be rejected, so that the security in the remote operation system 100 can be further enhanced.

  Note that, in the above description, the determination that the authentication code and the identification code match and the preset condition match is performed by the home appliance 1, but a cloud server that associates the home appliance 1 and the communication terminal 3 with the communication network 4 is provided. The cloud server may perform the above determination and transmit only the operation information from the appropriate communication terminal 3 to the home appliance 1. Alternatively, a home appliance adapter is provided in the home appliance 1 to enable communication via the communication network 4, the above determination is performed by the home appliance adapter, and only the operation information from the appropriate communication terminal 3 is transmitted to the home appliance 1. Also good.
