Description

  The present invention relates to a control system used in combination with various types of electrical equipment and devices, and more particularly to a remote control system for controlling electrical equipment and devices from a remote location.

  As shown in FIG. 3, a conventional air conditioner is known that includes a power line 201 to be plugged into a main power source such as an outlet and a power switch 203. A person (user) in a house or building to which the air conditioner 200 is attached can operate the switch 203 to control the operation of the air conditioner 200. In order to operate or stop this type of air conditioner from outside the installation site, a contact 204 that can be controlled from a remote location may be provided on the power line 201. If the power switch 203 is turned on when going out, the user can control the air conditioner 200 by opening and closing the contact 204 from outside the house such as a workplace. However, at present, this type of air conditioner is hardly manufactured or used, and it is difficult to say that it is a realistic method for realizing control from a remote location.

  The air conditioner of FIG. 3 described above is almost replaced by the air conditioner of FIG. 4 at present. The air conditioner 210 of FIG. 4 includes an electronic switch 206 that can be controlled by a signal transmission element capable of transmitting a signal, such as a handheld infrared (IR) remote controller 208, instead of the power switch 203. Such an air conditioner 210 also includes a receiving element capable of receiving a signal, such as the light receiving element 212, in the indoor unit, and receives infrared data (infrared signal) transmitted from the remote controller 208. The received data is used to start or stop the air conditioner 210 by operating the electronic switch 206. Thus, as long as the light receiving element 212 of the air conditioner 210 is located within the effective range of the remote controller 208, the user can remotely control the air conditioner 210 using the remote controller 208. Therefore, in the type of air conditioner of FIG. 4, it is not necessary to go to the installation position of the air conditioner in order to control its operation.

  The system shown in FIG. 4 achieves a temporary purpose as a remote control system, but has various problems. For example, the air conditioner of the type shown in FIG. 4 is controlled by an electronic switch, and the operation cannot be controlled by opening and closing the main power supply.

Can not. Therefore, it is very inconvenient when the user wants to air-condition the room when returning home. Since air conditioners consume a relatively large amount of power, it is not desirable to leave the room running for a long time to keep the room at a comfortable temperature. Therefore, a system for easily controlling an air conditioner and other electric devices from a remote place is desired.

  In addition, as a technology developed in recent years, there is a home automation (HA) system, which is currently used in many countries. Specifically, as shown in FIG. 5, an air conditioner 220 having an HA terminal 222 is used in combination with the HA dedicated controller 224, and the HA from outside the room or place where the air conditioner 220 is installed. The air conditioner 220 can be controlled via the terminal 222. However, HA system standards and standards differ depending on the country or region, and products imported from foreign countries cannot be controlled in this manner.

  FIG. 1 is a block diagram of a system 100 according to the present invention for controlling an electrical device such as an air conditioner from a remote location. The electrical equipment control system 100 includes a relay panel 2 and a switch system 1 that is connected to the relay board 2 and includes a plurality of electronic switches 3 that operate electrical devices and equipment (described in detail later) incorporated in the system 100. including. The electric equipment control system 100 also includes a network interface such as a public line interface 4 connected to a communication network such as a public line. The communication network that interfaces with the system of the present invention is not limited to a specific network, and may be the Internet, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network, a wireless network, or the like. The public line interface 4 is connected to the relay panel 2 and is configured so that the relay panel 2 can be operated not only from the electronic switch 3 but also from a mobile phone or a public telephone. Furthermore, the electric device control system 100 includes electric device interfaces such as an air conditioner interface 5 and a dehumidifier interface 15, and the air conditioner 7 and the dehumidifier 17 can be controlled via the respective interfaces. Each of the air conditioner 7 and the dehumidifier 17 includes a receiving element that can receive a signal, such as an infrared (IR) light receiving element 19, and can be remotely controlled by an attached remote controller 18. The electrical equipment interfaces 5 and 15 include power transformers (CT) 6 connected to the power cords of the electrical equipments 7 and 17, that is, the power supply lines 20, and can detect the load current of the corresponding electrical equipment.

  FIG. 2 is a block diagram showing the inside of the air conditioner interface 5. The function and configuration of the dehumidifier interface 15 are similar to those of the air conditioner interface 5. The air conditioner interface 5 receives infrared (IR) light for receiving infrared (IR) data from a central processing unit (CPU) 8 that controls the entire operation and a signal transmission device such as a remote controller 18 that can transmit signals. It includes an element 9, a data storage device 10 for storing received infrared data, and a system connection circuit 11 for establishing a communication path between the switch system 1 of the relay panel 2 and the air conditioner interface 5. In the present embodiment, the data storage device 10 is configured by an EEROM, but a storage device other than the EEROM can also be employed. Further, the interface 5 includes an infrared light emitting element 12 that transmits data, that is, a signal to the air conditioner 7, a comparison circuit 13 that determines an operation state of the air conditioner 7, and a current amperage detected by the CT 6 as a voltage value. A conversion circuit 14 for conversion is included.

  In the control system 100 configured as described above, first, the infrared remote controller 18 of the air conditioner 7 is operated, and an infrared signal including an ON signal for operating the air conditioner 7 and an OFF signal for stopping the air conditioner 7 is received as a light receiving element of the air conditioner interface 5. 9 to send. Next, the ON and OFF signals included in the infrared signal received by the light receiving element 9 are temporarily stored in the data storage device 10 of the interface 5 and later recalled and used.

  In order to start the air conditioner 7 from the outside of the room where the air conditioner 7 is installed, the user issues an ON command from, for example, a mobile phone or a public telephone. Note that a device that issues a user command is not limited to a telephone, and various devices can be used. A computer system, a laptop computer, a portable information terminal (PDA), a handy-type wireless device, and the above-described device Other devices that can interface to the network are included.

  When receiving an ON command from the user via the public line interface 4, the switch system 1 transmits an ON signal to the air conditioner interface 5. Next, the air conditioner interface 5 reads the stored ON command from the data storage device 10, and transmits an infrared signal including the ON command from the light emitting element 12 to the air conditioner 7, thereby starting the air conditioner 7. That is, the air conditioner interface 5 generates the same signal as the signal already received from the remote controller 18, thereby notifying (guaranteeing) that the air conditioner 7 operates correctly.

  Then, the conversion circuit 14 converts the amperage of the load current detected by the CT 6 into voltage data. The comparison circuit 13 determines the operating state of the air conditioner 7 using the obtained voltage data. Next, the air conditioner interface 5 feeds back the determined operation state to the switch system 1 via the system connection circuit 11. Thereafter, the information indicating the current operating state of the air conditioner 7 is transferred to the user as a voice message, voice message, visual message, graphic message, text message, or any combination of these messages. By doing so, the user can confirm that the air conditioner or other electric device incorporated in the electric device control system 100 has been started reliably.

  In order to stop the air conditioner 7 from the outside of the room where the air conditioner 7 is installed, the user issues an OFF command from a mobile phone, a public telephone, a computer, or any of the devices described above.

  When an OFF command is received from the user via the public line interface 4, the switch system 1 transmits an OFF signal to the air conditioner interface 5 in the same manner as the operation described above. Next, the air conditioner interface 5 reads the stored OFF command from the data storage device 10 and stops the air conditioner 7 by transmitting an infrared signal including the OFF command from the light emitting element 12 to the light receiving element 19 of the air conditioner 7. Let The air conditioner interface 5 transmits a feedback signal indicating the stop of the air conditioner 7 to the switch system 1. As described above, since the information indicating the operating state (here, the OFF state) of the air conditioner 7 is transferred to the user, the user can surely stop any electric device included in the air conditioner or the control system 100. I can know that.

  As described above, in the present embodiment, the switch system 1 can control the air conditioner 7 from a remote place by incorporating the air conditioner 7 as a part of the switch system. In addition, according to the electric device control system 100, it is possible to control an arbitrary number of air conditioners 7, dehumidifiers 17 and other electric devices that can be operated by a remote controller.

  The air conditioner interface 5 constantly monitors the current operating state of the air conditioner 7 by detecting the amperage of the current supplied to the air conditioner 7. Accordingly, when the infrared remote controller 18 is operated to start or stop the air conditioner 7, information indicating that the operation state has changed is fed back to the switch system 1, and the system 1 can always grasp the operation state of the air conditioner 7. . Further, the user can always grasp the operating state of the air conditioner 7. Further, as described above, the amperage of the current passing through the power line 20 of each electric device is always fed back to the interface of the electric device. Therefore, even if the air conditioner 7 does not start or stop after the user command is issued, the air conditioner interface 5 continues to repeatedly transmit the infrared signal for operating the air conditioner until the amperage reaches a value indicating execution of the operation. Such a function has an advantage that the user command is reliably executed. Similar to the above-described function, this function can be used not only for the air conditioner 7 in the present embodiment but also for any electric device incorporated in the system 100.

  In conventional systems, when a one-way controller, such as an infrared remote controller, is used to start or stop an air conditioner or other electrical device, the controller has a way to know whether the electrical device has worked as intended. There wasn't. However, the electrical device interfaces 5 and 7 of the present invention continuously monitor the operational state of the electrical device by detecting the amperage of the current supplied to the associated electrical device (ie, “load”). . Once the ON or OFF signal is sent, the electric device interface continues to transmit the signal repeatedly until it is confirmed that the electric device is operating or stopped. With this operation, the control system of the present invention realizes bidirectional communication while adopting the infrared remote controller.

  Further, in the above-described electrical equipment control system, the operating state (ON or OFF state in the above-described embodiment) is continuously monitored, so the electrical equipment incorporated in the system by a remote controller attached to the electrical equipment. Even if is started or stopped, it is immediately detected that the operating state has changed. Thereby, the information which the control system grasps | ascertains about the operation state of an electric equipment will always correspond with the actual operation state of an electric equipment.

  Furthermore, by combining the switch system 1 and the air conditioner interface 5 as in the above embodiment, even an air conditioner without an HA terminal or other dedicated external control terminal can be easily controlled from a remote location.

  In addition, according to the electrical equipment control system described above, any electrical or electronic appliance that can be wirelessly controlled by a remote controller can be controlled from a remote location outside the installation site, regardless of type, manufacturer, and country of manufacture. It becomes possible to do.

  In addition to adjusting the amperage level detected by the current transformer (CT), the control system described above can be used for various home and business electronic devices such as televisions and audio devices in addition to air conditioners and dehumidifiers. -It can also be used to control electrical equipment and devices.

  Furthermore, according to the control system described above, not only can the switch system be controlled by an electronic switch connected to the relay panel, but the switch system can also be controlled via a public line interface by a mobile phone, a public telephone, a computer, and other devices. It is also possible to do. Therefore, the user can start or stop an electrical device such as an air conditioner incorporated in the present system from a remote place, and can check its operating state.

  In addition, the structure of the electric equipment control system and electric equipment control method of this invention is not limited to the aspect of the said embodiment at all, It can change suitably in the range which does not deviate from the meaning of this invention.
