Description

  The present invention relates to a system configured to be able to remotely operate a device installed in a facility such as a house from a terminal outside the facility.

  In a system such as HEMS (Home Energy Management System), a user outside the facility can remotely control home appliances such as an air conditioner and a heater inside the facility using a terminal such as a smartphone. .

  In this type of system, when there is another user in the facility, remote operation of the equipment in the facility may be performed in a manner that is undesirable for the user in the facility. For example, there may be a case where a user inside the facility does not want the heating operation by the heater, but remotely operates the heater so that a user outside the facility performs the heating operation.

  As a system that can eliminate such inconveniences, for example, those disclosed in Patent Documents 1 and 2 have been proposed.

  In Patent Document 1, in a residential network system, a human sensor is installed in a house, and when the presence sensor detects the presence of a person in the house, an electric device in the house by a user outside the house. There has been proposed a system configured to disable remote control of the system.

  In Patent Document 2, the state change of the electrical device in the house is monitored by the HEMS controller, and when the state change of the electrical device is detected, it is considered that there is a person at home, and for a predetermined time. In the meantime, a system has been proposed that prohibits remote operation of home electrical devices by users outside the home.

JP 2003-198745 A Japanese Patent Laying-Open No. 2015-154419

  However, in the system shown in Patent Document 1, in order to detect with high reliability whether there is a person in the house, it is necessary to install a large number of human sensors in the house. For this reason, equipment costs tend to be expensive.

  Further, in the system shown in Patent Document 2, in a situation where a person in the house does not need to operate the electric device and does not operate the electric device, a user outside the home can remotely operate the electric device. The operation can be performed. For this reason, a remote operation for operating the electric device is performed by a user outside the home, which is not desired by the user at home.

  The present invention has been made in view of such a background, and obtains information that can reliably indicate whether or not a person exists in a facility without requiring a human sensor, and obtains the information. An object of the present invention is to provide a remote control system that can reflect the remote control of equipment in a facility.

  In order to achieve the above object, a first aspect of the device remote operation system of the present invention includes a function for controlling operation of a device provided in a facility, a terminal for remote operation of the device, and a public device. A controller having a function of performing communication via a communication network, the controller responding to a remote operation command given via the public communication network from the remote operation terminal existing outside the facility In the remote control system configured to be able to control the operation of the device, the controller has a portable terminal pre-registered in the facility as a portable terminal carried by a user who resides in the facility A function of detecting whether or not to do so by communication with the portable terminal in the short-range communication method, and the remote operation command is given from the remote operation terminal The operation control of the device according to the remote operation command is executed when it is not detected that the portable terminal exists in the facility, and the portable terminal exists in the facility. When detected, it is configured not to execute the operation control of the device according to the remote operation command (first invention).

  In the present invention, the short-range communication method is a radio wave for communication (predetermined frequency band) in an area outside the facility or an area outside the facility excluding an area near the facility. Means a communication system in which the radio waves are transmitted so that it is substantially difficult to receive the radio waves. As the short-range communication method, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like may be employed.

  According to the first aspect, the controller detects whether a pre-registered mobile terminal is present in the facility by communicating with the mobile terminal using a short-range communication method.

  Here, since the short-range communication method is the communication method described above, the portable terminal is present in the facility when communication between the controller and the portable terminal can be performed (facility It may be considered that it exists in the vicinity of In addition, in a state where communication between the controller and the mobile terminal cannot be performed, it can be considered that the mobile terminal does not exist in the facility.

  Accordingly, the communication between the controller and the portable terminal allows the controller to detect whether or not the portable terminal exists in the facility.

  In this case, since the portable terminal is a portable terminal carried by the user, if the portable terminal exists in the facility, the user who carries the portable terminal may also exist in the facility. high. Therefore, the information on whether or not the portable terminal is present in the facility is information indicating whether or not the user who carries the portable terminal exists in the facility with high reliability.

  Moreover, the said portable terminal does not need to be a thing only for a remote control system, and a personal smart phone, a mobile phone, a tablet terminal, etc. which each user carries on a daily basis can be used as said portable terminal.

  Therefore, the controller can communicate information that can reliably indicate whether or not a user (person) exists in the facility by communicating with a portable terminal carried by each user without requiring a human sensor. Can be acquired.

  When the remote operation command is given from the remote operation terminal, the controller controls the operation of the device according to the remote operation command, and the portable terminal exists in the facility. Execute if not detected.

  As a result, in a situation where there is no user in the facility, the operation control of the device is executed according to the user's request for operating the remote operation terminal (in response to the remote operation command).

  In addition, the controller does not execute the operation control of the device according to the remote operation command when it is detected that the portable terminal is present in the facility.

  As a result, it is possible to prevent the operation control of the device not desired by the user from being executed with high reliability in a situation where the user exists in the facility.

  Therefore, according to the first aspect of the present invention, information that can indicate with high reliability whether or not a person (user) exists in the facility is acquired without requiring a human sensor, and the information is reflected. Remote operation of equipment in the facility can be performed.

  The second aspect of the device remote control system according to the present invention includes a function for controlling the operation of a device provided in a facility and a terminal for remote control of the device in order to achieve the above object. And a controller having a function of performing communication via the public communication network, the remote operation command given via the public communication network from the remote operation terminal that exists outside the facility. In the remote operation system configured to be able to control the operation of the device according to the control, the controller is configured so that a portable terminal registered in advance as a portable terminal carried by a user who resides in the facility is in the facility. Is detected by communication with the portable terminal in the short-range communication method, and the remote operation command is received from the remote operation terminal. When it is obtained, the operation control of the device according to the remote operation command is executed when it is not detected that the portable terminal exists in the facility, and the portable terminal exists in the facility. If it is detected, the in-facility presence information indicating the presence of the mobile terminal is transmitted to the remote operation terminal, and then the operation control of the device should be performed within a predetermined time. When a command is received from the remote operation terminal, the operation control of the device is executed according to the remote operation command, and the command to the effect that the operation control of the device should be performed within the predetermined time is When not receiving from the terminal for remote operation, it is comprised so that execution of the operation control of the said apparatus according to the said remote operation command may be stopped (2nd invention).

  In the present invention, the meaning of the short-range communication method is the same as that of the first invention.

  According to the second invention, as in the first invention, the controller needs a human sensor for information that can indicate with high reliability whether or not a user (person) exists in the facility. Instead, it can be obtained by communication with a portable terminal carried by each user.

  When the remote operation command is given from the remote operation terminal, the controller controls the operation of the device according to the remote operation command, and the portable terminal exists in the facility. Execute if not detected.

  As a result, in a situation where there is no user in the facility, the operation control of the device is executed according to the user's request for operating the remote operation terminal (in response to the remote operation command).

  On the other hand, if it is detected that the mobile terminal is present in the facility, the controller transmits the facility presence information indicating the presence of the mobile terminal to the remote operation terminal, and then When an instruction to control the operation of the device within a predetermined time is received from the remote operation terminal, the operation control of the device according to the remote operation command is executed.

  For this reason, a user who operates the terminal for remote operation (hereinafter sometimes referred to as a remote operation user) recognizes that there is another user in the facility by receiving the facility presence information. Will be able to.

  Then, after the remote operation user recognizes that another user exists in the facility, he / she selects to execute the operation control of the device, and sends a command to that effect from the remote operation terminal. When transmitted, the controller that has received the command executes operation control of the device in accordance with the remote operation command. Therefore, the operation control of the device is executed according to the desire of the remote operation user.

  On the other hand, if the remote operation user does not choose to execute the operation control of the device in response to the recognition that another user exists in the facility, the remote operation terminal Therefore, a command to execute the operation control of the device is not transmitted. In this case, since the controller does not receive a command to control the operation of the device within the predetermined time, the controller stops the operation control of the device according to the remote operation command.

  As described above, the remote operation user can select whether or not to perform the operation control of the device in response to recognizing that another user exists in the facility, and the selection result. Can be reflected in the operation control of the equipment.

  Therefore, according to the second aspect of the present invention, information that can indicate with high reliability whether or not a person (user) exists in the facility is acquired without requiring a human sensor, and the information is reflected. Remote operation of equipment in the facility can be performed.

  And in 2nd invention, when a user exists in a plant | facility, operation control of an apparatus will not be performed uniformly, but the remote operation user recognized that the user exists in the plant | facility In the above, it is possible to select whether or not to execute the operation control of the device. Therefore, it is possible to accurately reflect the desire of the remote operation user in the operation control of the device.

  In the second aspect of the invention, when the controller performs operation control of the device in response to the remote operation command in a situation where it is detected that the portable terminal is present in the facility, the controller operates the device. It is preferable that the information indicating that the control is executed is configured to be transmitted to the portable terminal that is detected to be present in the facility (third invention).

  According to this, the user carrying the portable terminal detected to be present in the facility can quickly recognize that when the operation control of the device by remote operation is executed. . For this reason, the user carrying the portable terminal can quickly stop the operation control when the operation control of the device is not desired by the user. Furthermore, the user carrying the portable terminal can appropriately notify the remote operation user of the suspension of the operation control.

  In the first to third aspects of the invention, the controller may adopt the following form as a form of communication with the portable terminal for detecting that the portable terminal is present in the facility.

  In an example thereof, the portable terminal is configured to periodically transmit a predetermined signal receivable by the controller using the short-range communication method, and the controller is configured to transmit the predetermined signal. The mobile terminal is configured to detect whether or not the portable terminal exists in the facility based on the presence or absence of reception (fourth invention).

  In another example, the portable terminal transmits a response signal receivable by the controller using the short-range communication method when receiving a predetermined signal transmitted from the controller. The controller is configured to periodically transmit the predetermined signal receivable by the portable terminal using the short-range communication method, and to respond to the response signal according to the transmission of the predetermined signal. It is configured to detect whether or not the portable terminal is present in the facility based on whether or not there is reception (fifth invention).

  According to these 4th invention and 5th invention, the controller can detect whether this portable terminal exists in a facility by a simple communication form with a portable terminal.

[First Embodiment]
A first embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the remote operation system 1 of the present embodiment is for remote operation of a device 2 installed in a home H (house, dwelling unit, etc.) as an example of a facility. This is a system configured to be performed from the terminal 3 via the public communication network 4. The public communication network 4 is a wide area network composed of the Internet, a telephone line network, and the like.

  The terminal 3 for remote operation (hereinafter simply referred to as the remote operation terminal 3) is a terminal that can be connected to the public communication network 4 by radio or wire. The remote operation terminal 3 is composed of, for example, a smartphone, a mobile phone (feature phone), a tablet terminal, a personal computer, or the like. The remote operation terminal 3 may be either a portable type or a stationary type.

  The remote operation terminal 3 is preinstalled with an application for remote operation of the device 2. Then, by operating the remote operation terminal 3 in a state where the application is activated, a remote operation command (command for starting or stopping the operation of the device 2 or operation of the device 2 is performed) Setting information (timer time, target value, etc.) can be transmitted to the device 2 side via the public communication network 4. The remote operation terminal 3 can also receive information such as the operating state of the device 2 from the device 2 via the public communication network 4.

  The remote operation terminal 3 may be either individually owned by each resident (user) of the home H or shared.

  As an example of the apparatus 2, an air conditioner, a floor heating apparatus, a bathroom heating apparatus, etc. are mentioned, for example. However, the device 2 may be a device other than the above as long as it can perform remote operation. Further, the device 2 to be remotely operated may be a plurality of devices.

  A controller 10 is mounted on the device 2 to be remotely operated. The controller 10 includes one or a plurality of electronic circuit units including a CPU, a RAM, a ROM, an interface circuit, a communication device, and the like.

  The controller 10 functions as an operation control unit 11 that performs operation control of the device 2 and functions as a communication processing unit 12 that executes communication processing with the outside as functions realized by the installed program or hardware configuration. And a function as a terminal detection unit 13 that detects whether or not the mobile terminal 5 is present in the home H.

  The operation control unit 11 controls the operation of the device 2 according to an operation of an operating device (not shown) for the device 2 or according to a remote operation command given from the remote operation terminal 3.

  The communication processing unit 12 executes a communication process between the remote operation terminal 3 and the controller 10 and a communication process between the portable terminal 5 and the controller 10.

  In the communication between the remote operation terminal 3 and the controller 10, the controller 10 is connected to the public communication network 4 via the gateway device 6 installed in the home H. In this state, the controller 10 and the remote operation terminal are connected. Communication with the machine 3 is performed via the public communication network 4.

  In this case, the communication method between the controller 10 and the gateway device 6 may be either a wired method using a LAN cable or the like, or a wireless method using Wi-Fi (registered trademark) or the like. Note that the gateway device 6 may include a function as a router.

  The portable terminal device 5 is a terminal device that each resident of the home H carries on a daily basis. The mobile terminal 5 is configured by a smartphone, a mobile phone (feature phone), a tablet terminal, or the like.

  Each resident's portable terminal 5 is a portable terminal carried by each resident and a terminal that can communicate with the device 2 in the home H (a terminal belonging to a local network including the device 2). Are previously registered in the controller 10 (or the gateway device 6). The communication between each portable terminal 5 and the controller 10 is not performed via the public communication network 4 but by a short-range wireless communication method such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). , Directly or via the gateway device 6.

  The terminal detector 13 detects whether or not each mobile terminal 5 is present in the home H as will be described later, based on communication between each mobile terminal 5 and the controller 10.

  Supplementally, the controller 10 may be arranged outside the device 2. When the remote operation target device 2 is composed of a plurality of devices, the controller 10 may have a function of comprehensively managing the operation of the plurality of devices (for example, a HEMS controller). . The controller 10 may include a function as a gateway. In this case, the gateway device 6 can be omitted.

  Next, the action | operation regarding the remote control of the apparatus 2 is demonstrated concretely.

  The controller 10 repeats the process shown in the flowchart of FIG. In STEP 1, the controller 10 receives the access from the remote operation terminal 3 outside the home and determines whether or not the remote operation command for the device 2 has been received from the remote operation terminal 3 via the communication processing unit 12. To monitor sequentially. The state in which the determination result of STEP 1 is negative is a state of waiting for reception of a remote operation command. In this state, the determination process of STEP 1 is continued.

  If the determination result in STEP 1 becomes affirmative, the controller 10 next determines in STEP 2 whether or not the mobile terminal 5 is present in the home H by the terminal detector 13. This determination process is performed as follows, for example.

  In the present embodiment, each resident's portable terminal 5 is pre-installed with an application that causes the portable terminal 5 to periodically execute the process shown in the flowchart of FIG. 3 as a background process. In this process, in STEP 11, a clock timer that counts a predetermined time (for example, 30 seconds) is reset (time value initialization) and started. Furthermore, in STEP 12, the determination process of whether or not the 30-second clocking by the clock timer has ended is continued until the determination result becomes affirmative.

  When the time measurement for 30 seconds is completed and the determination result in STEP 12 becomes affirmative, the portable terminal 5 detects whether or not the portable terminal 5 exists in the home H in STEP 13. A confirmation signal to be used is transmitted. The confirmation signal is a signal in a wireless communication system (Wi-Fi (registered trademark), Bluetooth (registered trademark), etc.) for communication with the controller 10 and includes an identification code of the mobile terminal 5 that is the transmission source. It is out. After the processing of STEP13, the processing from STEP11 is resumed. The confirmation signal corresponds to the predetermined signal in the present invention.

  With this process, the mobile terminal 5 transmits a confirmation signal every predetermined time (every 30 seconds).

  Meanwhile, the controller 10 repeats the process shown in the flowchart of FIG. 4 by the terminal detection unit 13 in order to determine whether or not the mobile terminal 5 exists in the home H.

  In this process, the terminal detection unit 13 executes reset (initialization of the time value) and activation of a time timer that measures a predetermined time (for example, 30 seconds) in STEP 21. The predetermined time may be longer than the cycle in which the mobile terminal 5 transmits the confirmation signal.

  Next, in STEP 22, the terminal detection unit 13 determines whether the confirmation signal transmitted from the mobile terminal 5 is received by the communication processing unit 12. In a state in which the determination result in STEP 22 is negative, the terminal detector 13 determines in STEP 25 whether or not the timing of the clock timer started in STEP 21 (30 seconds) has ended. And the terminal detection part 13 continues the determination process of STEP22, 25 until the determination result of STEP22 becomes affirmative or the determination result of STEP25 becomes affirmative.

  When the determination result of STEP 22 is negative (the controller 10 does not receive the confirmation signal) and the time measurement of 30 seconds by the clock timer is completed, the determination result of STEP 25 is positive.

  Here, when any one of the resident's portable terminals 5 is present in the home H, the portable terminal 5 transmits a confirmation signal every 30 seconds by the process of FIG. 3 described above. Therefore, the controller 10 receives the confirmation signal before the determination result of STEP 25 becomes affirmative, and as a result, the determination result of STEP 22 becomes affirmative.

  Therefore, the situation in which the determination result in STEP 25 is affirmative is a situation in which none of the resident portable terminals 5 can be regarded as being present in the home H. Therefore, when the determination result in STEP 25 is affirmative (when the confirmation signal is not received during the time measurement by the clock timer), the terminal detection unit 13 determines that the mobile terminal device in the home H is in STEP 26. It is determined that 5 does not exist.

  On the other hand, if the confirmation signal is received by the communication processing unit 12 before the determination result of STEP 25 becomes positive, and the determination result of STEP 22 becomes affirmative, the terminal detection unit 13 In STEP 23, it is determined whether or not the mobile terminal that is the transmission source of the received confirmation signal is the mobile terminal 5 registered in advance as that of the resident. This determination is performed by collating the identification code of the transmission source of the received confirmation signal with the identification code of the resident portable terminal 5 registered in advance in the controller 10 (or the gateway device 6).

  When the determination result of STEP 23 is negative, the confirmation signal received by the controller 10 is transmitted from a mobile terminal of an outsider who exists within a short distance from the home H. Can be considered. Therefore, if the determination result in STEP 23 is negative, the terminal detection unit 13 regards that the confirmation signal from the resident portable terminal 5 is not received by the controller 10, and from the STEP 25. Execute the process.

  If the determination result in STEP 23 is affirmative, it means that the controller 10 has received the confirmation signal transmitted from the portable terminal 5 of the resident. Therefore, in this case, the terminal device detection unit 13 determines in STEP 24 that the mobile terminal device 5 exists in the home H.

  Supplementally, even if the resident carrying the portable terminal 5 is outside the home H, the controller 10 receives the confirmation signal transmitted from the portable terminal 5 by the position of the resident. If the position is within the range to be obtained (the position within the communicable area in the short-range wireless communication system), the determination results of STEPs 22 and 23 are positive. In this case, although the resident's mobile terminal 5 is strictly located outside the home H, its location is sufficiently close to the home H, so that the resident temporarily Therefore, it is highly likely that they are outside the home H (such as a garden).

  Therefore, in this embodiment, the terminal detection unit 13 is not limited to the case where the resident portable terminal 5 is actually present in the home H, but the mobile terminal 5 is within a range sufficiently close to the home H. In STEP 24, it is determined that the mobile terminal 5 is present in the home H, including the case where the confirmation signal is within the range in which the controller 10 can receive the signal.

  In STEP 2 of FIG. 2, it is determined whether or not the resident portable terminal 5 exists in the home H as described above.

  If the determination result in STEP 2 is affirmative (when it is determined that the resident mobile terminal 5 is present in the home H), the owner (resident) of the mobile terminal 5 is also in the home H. It can be considered that it exists (including the case where it exists in the vicinity of home H).

  In this case, the controller 10 does not execute the operation control of the device 2 based on the remote operation command in STEP 3, and transmits information indicating that to the remote operation terminal via the gateway device 6 and the public communication network 4. Transmit to machine 3.

  Further, when the determination result of STEP 2 is negative (when it is determined that the resident's mobile terminal 5 does not exist in the home H), that is, no resident exists in the home H. When obtaining, the controller 10 performs operation control of the apparatus 2 by the operation control part 11 based on a remote operation command in STEP4.

  After the processing in STEP 3 and 4, the processing from STEP 1 is resumed.

  As described above, in the present embodiment, when any one of the mobile terminal devices 5 that each resident of the home H carries on a daily basis exists in the home H (including the case where the mobile terminal 5 exists in the vicinity of the home H). The operation control of the device 2 based on the remote operation command from the remote operation terminal 3 is not executed, and based on the remote operation command only when none of the mobile terminals 5 of each resident is present in the home H. Operation control of the device 2 is executed.

  As a result, when any resident exists in the home H or when the possibility is high, the operation control of the device 2 based on the remote operation command is not executed. For this reason, it can prevent that the operation control of the apparatus 2 undesirable for the resident who exists in the home H is performed.

  In this case, information indicating that the operation control of the device 2 is not executed because the resident who is different from the resident who operates the remote operation terminal 3 exists in the home H is the remote operation terminal. Since the resident who tried to remotely operate the device 2 by the remote operation terminal 3 (hereinafter, sometimes referred to as a remote operation user), the operation control of the device 2 is not performed. Can be recognized.

  Whether or not the portable terminal 5 exists in the home H by communication between the controller 10 and the portable terminal 5 carried by each resident on a daily basis (whether or not the controller 10 receives a confirmation signal). As a result, it can be detected with high reliability whether or not each resident exists in the home H. For this reason, the controller 10 can select appropriately whether to perform the operation control of the device 2 based on the remote operation command.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. Note that this embodiment is different from the first embodiment only in the determination process of STEP 2 (the process of the terminal detection unit 13). For this reason, in the description of the present embodiment, the description of the same matters as in the first embodiment is omitted.

  In the present embodiment, a confirmation signal for exploringly detecting whether or not the resident portable terminal 5 is present in the home H is transmitted from the controller 10. And the portable terminal 5 will transmit the response signal with respect to it, if the said signal for a confirmation is received.

  Specifically, in this embodiment, in this embodiment, each resident's portable terminal device 5 is an application that causes the portable terminal device 5 to periodically execute the processing shown in the flowchart of FIG. 5 as background processing. Is pre-installed. In this process, the portable terminal 5 monitors whether or not the confirmation signal transmitted from the controller 10 is received in STEP 31.

  And the portable terminal 5 will transmit a response signal in STEP32 next, if the signal for a confirmation is received and the judgment result of STEP31 becomes affirmative. This response signal is a signal in a wireless communication system (Wi-Fi (registered trademark), Bluetooth (registered trademark), etc.) for communication with the controller 10, and includes the identification code of the portable terminal 5 that is the transmission source. Yes. After the processing of STEP 32, the processing from STEP 31 is resumed.

  On the other hand, the controller 10 repeats the process shown in the flowchart of FIG. 6 by the terminal detection unit 13 in order to determine whether or not the mobile terminal 5 exists in the home H.

  In this process, the terminal detection unit 13 performs reset (initialization of a time value) and activation of a first time timer that measures a predetermined time (for example, 30 seconds) in STEP 41.

  Next, in STEP 42, the terminal detection unit 13 determines whether or not the clocking of the first clock timer started in STEP 41 (30 seconds clocking) has ended. When the timing of the first timer ends and the determination result in STEP 42 becomes affirmative, in STEP 43, the terminal detector 13 transmits a confirmation signal via the communication processor 12. The confirmation signal is a signal in a wireless communication system (Wi-Fi (registered trademark), Bluetooth (registered trademark), etc.) for communication with the portable terminal 5, and includes an identification code of the controller 10 of the transmission source. It is out.

  Next, in STEP 44, the terminal detector 13 resets (initializes the time value) and starts a second time timer that measures a predetermined time (for example, 1 minute).

  Furthermore, in STEP 45, the terminal detection unit 13 determines whether the response signal transmitted from the mobile terminal 5 is received by the communication processing unit 12. In a state in which the determination result in STEP 45 is negative, the terminal detector 13 determines in STEP 48 whether or not the time measurement (time measurement for 1 minute) of the second clock timer started in STEP 44 has ended. Then, the terminal detector 13 continues the determination process of STEPs 45 and 48 until the determination result of STEP 45 becomes positive or the determination result of STEP 48 becomes positive.

  Here, when any one of the resident's mobile terminals 5 is present in the home H, the mobile terminal 5 receives the confirmation signal transmitted from the controller 10 in STEP 43. A response signal is transmitted by the process of FIG. For this reason, the controller 10 receives the response signal through the communication processing unit 12 before the determination result of STEP 48 becomes affirmative, and as a result, the determination result of STEP 45 becomes affirmative.

  Therefore, the situation in which the determination result in STEP 48 is affirmative is a situation in which none of the resident portable terminals 5 can be regarded as being present in the home H. Therefore, if the determination result in STEP 48 is affirmative (if no response signal is received during the time counting of the second clock timer), the terminal detector 13 determines that the mobile terminal is in the home H in STEP 49. It is determined that the machine 5 does not exist.

  On the other hand, if the response signal is received by the communication processing unit 12 before the determination result of STEP 48 becomes affirmative, the determination result of STEP 45 becomes affirmative. It is determined in STEP 46 whether or not the portable terminal device that has transmitted the response signal is the portable terminal device 5 registered in advance as that of the resident. This determination is performed by collating the identification code of the source of the received response signal with the identification code of the resident portable terminal 5 registered in advance in the controller 10 (or gateway device 6).

  When the determination result of STEP 46 is negative, the response signal received by the controller 10 is within a short distance range from the home H, as in the case where the determination result of STEP 23 in the first embodiment is negative. Can be regarded as being transmitted from an outsider's mobile terminal. Therefore, if the determination result in STEP 46 is negative, the terminal detection unit 13 regards that the response signal from the resident portable terminal 5 is not received by the controller 10, and the process from STEP 48. Execute.

  If the determination result in STEP 46 is positive, it means that the controller 10 has received a response signal transmitted from the resident portable terminal 5. Therefore, in this case, the terminal detector 13 determines in STEP 47 that the mobile terminal 5 is present in the home H (including the case where the mobile terminal 5 is present in the vicinity of the home H).

  As described above, in the present embodiment, the confirmation signal is periodically transmitted from the controller 10 (every 30 seconds), and the response signal from the portable terminal 5 is received within a predetermined time (1 minute) from the transmission timing. Whether or not the mobile terminal 5 is present in the home H is determined based on whether or not it is received by the controller 10.

  The present embodiment is the same as the first embodiment except for the matters described above. In this embodiment, the same effect as that of the first embodiment can be obtained.

[Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, only a part of the processing of the controller 10 is different from the first embodiment or the second embodiment. For this reason, in the description of the present embodiment, the description of the same matters as those in the first embodiment or the second embodiment is omitted.

  In the present embodiment, the controller 10 repeats the process shown in the flowchart of FIG. In STEP 51, the controller 10 receives the access from the remote operation terminal 3 outside the home and determines whether or not the remote operation command for the device 2 has been received from the remote operation terminal 3 via the communication processing unit 12. To monitor sequentially. The state in which the determination result in STEP 51 is negative is a state of waiting for reception of a remote operation command. In this state, the determination process in STEP 51 is continued.

  If the determination result in STEP 51 becomes affirmative, the controller 10 next determines in STEP 52 whether or not the mobile terminal 5 exists in the home H by the terminal detector 13. This determination process is the same as in the first embodiment or the second embodiment.

  When the determination result in STEP 52 is negative (when it is determined that the resident mobile terminal 5 does not exist in the home H), that is, when no resident is present in the home H In STEP 53, the controller 10 causes the operation control unit 11 to perform operation control of the device 2 based on the remote operation command.

  On the other hand, when the determination result in STEP 52 is affirmative (when it is determined that the resident portable terminal 5 is present in the home H), the controller 10 then remotely moves into the home H in STEP 54. Information indicating that there is a mobile terminal 5 of a resident other than the resident who operated the operation terminal 3 (or that there is a resident who is the owner of the mobile terminal 5), information on the gateway device 6 and The data is transmitted to the remote operation terminal 3 via the public communication network 4. Note that the information transmitted to the remote operation terminal 3 in STEP 54 corresponds to the facility presence information in the present invention.

  Further, in STEP 55, the controller 10 executes reset (initialization of the time value) and activation of a time timer that measures a predetermined time (for example, 5 minutes).

  Here, the remote operation terminal 3 that has received the information transmitted in STEP 54 has the mobile terminal 5 of another resident in the home H with respect to the remote operation user who has operated the remote operation terminal 3. The presence (or the presence of the other resident) is notified visually or audibly. Thereby, the remote operation user can recognize that another resident exists in the home H.

  Furthermore, in addition to the above notification, the remote operation terminal 3 outputs a notification that prompts the user to perform a selection operation on whether or not to actually perform the operation control of the device 2 within the predetermined time (5 minutes). (Visual or audible notification output) is generated.

  Then, in response to the notification output, when the remote operation user performs a selection operation as to whether or not the operation control of the device 2 should actually be performed, the operation of the device 2 is performed from the remote operation terminal 3 accordingly. An execution permission / inhibition command indicating whether or not the control can be executed is transmitted to the controller 10 via the public communication network 4.

  Therefore, after executing the processing of STEP 55, the controller 10 next determines whether or not the execution enable / disable instruction from the remote operation terminal 3 is received by the communication processing unit 12 in STEP 56. In a state in which the determination result in STEP 56 is negative, the controller 10 determines in STEP 57 whether or not the time measurement (time measurement of 5 minutes) started in STEP 55 has ended. Then, the controller 10 continues the determination processing of STEPs 56 and 57 until the determination result of STEP 56 becomes affirmative or the determination result of STEP 57 becomes affirmative.

  If the determination result of STEP 56 remains negative (the controller 10 does not receive the execution enable / disable command) and the time measurement by the time timer ends for 5 minutes, the determination result of STEP 57 becomes positive. In this case, the controller 10 assumes that the remote operation of the device 2 by the remote operation user has been canceled, and resumes the processing from STEP 51 without executing the operation control of the device 2.

  In this case, information indicating that the operation control of the device 2 has not been executed may be transmitted from the controller 10 to the remote operation terminal 3.

  On the other hand, when the determination result of STEP 56 becomes positive because the communication processing unit 12 receives the execution enable / disable command from the remote operation terminal 3 before the determination result of STEP 57 becomes positive. In STEP 58, the controller 10 determines whether or not the received execution enable / disable command is a command (executable command) indicating that the operation control of the device 2 based on the remote operation command is to be executed.

  When the determination result in STEP 58 is negative (when the execution enable / disable command is a non-executable command), the controller 10 does not execute the operation control of the device 2 in accordance with the execution enable / disable command, and from STEP 51. Resume processing. In this case, information indicating that the operation control of the device 2 has not been executed may be transmitted from the controller 10 to the remote operation terminal 3.

  When the determination result in STEP 58 is affirmative (when the execution permission / inhibition instruction is an execution permission instruction), the controller 10 performs the remote operation in STEP 59 according to the request of the remote operation user by the operation control unit 11. Based on the command, the operation control of the device 2 is executed.

  Further, in this case, the controller 10 controls the operation of the device 2 in response to a remote operation command from the remote operation terminal 3 to the portable terminal 5 detected to be present in the home H in STEP 60. The information indicating that has been executed is transmitted. Thereafter, the processing from STEP 51 is resumed.

  The present embodiment is the same as the first embodiment or the second embodiment except for the matters described above.

  In this embodiment, when the terminal detection unit 13 of the controller 10 detects that the mobile terminal 5 of any resident exists in the home H (including the case where it exists in the vicinity of the home H). In addition, the remote operation user can select whether or not the controller 10 should actually execute the operation control of the device 2 by the remote operation after recognizing that fact.

  Accordingly, not only when the resident portable terminal 5 is not present in the home H, but also when the portable terminal 5 is present (including the case where the resident portable terminal 5 is present in the vicinity of the home H), If desired, the controller 10 can execute operation control of the device 2 by remote control.

  Further, when the resident portable terminal 5 is present in the home H (including the case where the resident mobile terminal 5 is present in the vicinity of the home H), the controller 10 controls the operation of the device 2 by remote operation according to the request of the remote operation user. When it is executed, information to that effect is transmitted to the mobile terminal 5 existing in the home H. For this reason, the resident who is the owner of the portable terminal 5 can quickly recognize the execution of the operation control of the device 2 by remote operation, and if the operation control is not his / her own, The operation control can be stopped by the operation of the device 2 in H. Furthermore, the resident who is the owner of the portable terminal 5 can appropriately notify the remote control user that the operation control has been stopped or is about to be stopped.

  In addition, if the operation control of the device 2 by remote operation is not inconvenient for itself, the resident who is the owner of the portable terminal 5 can continue the operation control as desired by the remote operation user. .

  Therefore, according to the present embodiment, when it is detected that the mobile terminal 5 of any resident exists in the home H, the desire of the remote operation user and the owner of the mobile terminal 5 The hope can be accurately reflected in the operation control of the device 2 in a balanced manner.

  In each of the embodiments described above, the home H is shown as an example of the facility, but the facility in the present invention may be, for example, a work facility where a plurality of workers go in and out.
