[Constitution]
First, the configuration of the lighting control system according to the embodiment will be described with reference to FIG.

FIG. 1 is a configuration diagram showing an example of the lighting control system 100 according to the embodiment.

The lighting control system 100 includes an operation terminal 10, a transmission unit 20, a wireless access point (wireless AP) 30, and a plurality of loads 40. The plurality of loads 40 include a lighting device. In the lighting control system 100, the operation terminal 10, the transmission unit 20, and the wireless AP 30 are connected to each other by a power line 110. In the lighting control system 100, in addition to these devices, another operation terminal, a relay or a sensor for switching on / off of power supply to the load 40, etc. may be connected to the power line 110, but the illustration is omitted. .. The lighting control system 100 is a system in which the transmission unit 20 plays a central role (in other words, the transmission unit 20 serves as a master unit) and can control a load 40 such as a lighting device to be controlled by the lighting control system 100. Is. The control of the lighting device as the load 40 includes on / off control, dimming control, scene control, monitoring control, and the like of the lighting device. Scene control is used by lighting devices such as office areas, entrances, conference rooms, break rooms, Japanese-style rooms, Western-style rooms, bedrooms, and dens, or lighting devices such as morning, noon, night, meal time, and group time. It is to control the dimming and toning of the lighting device according to the time zone and the like. Monitoring control is to monitor the control state of the lighting device. These controls can be performed by the user operating the operation terminal 10.

The transmission unit 20 is a master controller that operates mainly in the lighting control system 100. The transmission unit 20 transmits a signal from the operation terminal 10 connected to the power line 110 to the load 40 via the wireless AP 30. The load 40 may be connected to the power line 110 without going through the wireless AP 30, and the transmission unit 20 may directly transmit a signal from the operation terminal 10 connected to the power line 110 to the load 40. ..

The wireless AP 30 wirelessly communicates with the load 40, and sets the load 40 in response to an instruction from the transmission unit 20 (specifically, information transmitted by the operation terminal 10 to the transmission unit 20 for controlling the load 40). Control. For example, when the wireless AP30 receives an instruction to turn on a specific illuminating device as a load 40, the wireless AP30 controls the specific illuminating device to turn on the specific illuminating device and turns off the specific illuminating device. When instructed, the particular luminaire is controlled to turn off the particular luminaire. The load 40 may be connected to the power line 110 via a relay or the like instead of the wireless AP 30. In this case, when the relay is instructed to turn on the power supply to the load 40 connected to itself, the relay turns on the power supply to the load 40 connected to itself and to the load 40 connected to itself. When instructed to turn off the power supply, the power supply to the load 40 connected to itself is turned off.

Although the lighting control system 100 includes a transmission unit 20, it may not be provided, and the operation terminal 10 and the wireless AP 30 or the load 40 may communicate with each other by the power line 110 without going through the transmission unit 20. ..

In the lighting control system 100, for example, a time-division multiplex transmission system is adopted, and the power line 110 includes a two-wire type power line. In the power line 110, a signal (information) is transmitted by a pulse signal due to a potential difference (for example, ± 24V) between the two lines. That is, power supply and information transmission can be performed simultaneously by the power line 110. Further, in the lighting control system 100, for example, a cyclic transmission method is adopted, and the signal transmitted from the transmission unit 20 passes through all the devices connected to the power line 110. Each device confirms the content of the signal, and the device requiring the signal receives the signal according to the content. For example, each device receives the signal when the signal includes its own address information, and ignores the signal when the signal does not include its own address information. This type of lighting control system includes, for example, a system such as NMAST®.

According to the lighting control system 100, wiring for connecting the load 40 and the operation terminal 10 on a one-to-one basis becomes unnecessary. Specifically, when there are eight loads 40, at least eight power lines (or signal lines) and one ground line are required to connect the load 40 and the operation terminal 10 by one-to-one wiring. However, in the lighting control system 100, only the power line 110 composed of two wires is sufficient. Thereby, for example, in a large-scale building, the wiring in the lighting control system 100 can be reduced.

The operation terminal 10 is a device that receives an operation for the user to control a load 40 including a lighting device, and is provided on, for example, a wall of a facility. The operation terminal 10 has not only a function for controlling the load 40 but also a function for using at least one or more information of sounds, characters, and images. The details of the operation terminal 10 will be described with reference to FIGS. 2 and 3.

FIG. 2 is a configuration diagram showing an example of the operation terminal 10 according to the embodiment. FIG. 3 is an external front view showing an example of the operation terminal 10 according to the embodiment.

The operation terminal 10 is a device including a processor (microprocessor), a memory, a communication interface, and the like. The memory is a ROM, RAM, or the like, and can store a control program executed by the processor. The operation terminal 10 includes an operation unit 11, a notification unit 12, a communication unit 13, an acquisition unit 14, a conversion unit 15, and a first display unit 16.

The operation unit 11 has a configuration for receiving an operation for controlling the load 40 including the lighting device, and is, for example, a switch or a button provided on the housing of the operation terminal 10 as shown in FIG. By operating the operation unit 11, information for controlling the load 40 is generated according to the operation. Specifically, when the processor of the operation terminal 10 executes the control program stored in the memory, information for controlling the load 40 according to the operation is generated.

The notification unit 12 is configured to notify at least one or more information of sound, characters, and images, and as shown in FIG. 3, for example, a second display unit that displays at least one or more information of characters and images. Including. The second display unit is, for example, signage. As described above, in order to realize not only the function for controlling the load 40 but also the function using at least one or more information of sounds, characters and images, the operation terminal 10 is notified in addition to the operation unit 11. It has a part 12. For example, FIG. 3 shows an example in which the information "leaving the office on time" is notified (displayed) by the notification unit 12 as an example of the character information. For example, when the communication unit 13 receives at least one or more information of characters and images, or the acquisition unit 14 described later acquires the information, the notification unit 12 notifies the information. Specifically, when the processor of the operation terminal 10 executes the control program stored in the memory, the notification unit 12 notifies the information.

The communication unit 13 is a communication interface that transmits information for controlling the load 40 and receives or transmits at least one or more information of sounds, characters, and images by the same transmission method. For example, the processor of the operation terminal 10 transmits and receives such information by executing a control program stored in the memory. The communication unit 13 communicates via the power line 110, and the operation terminal 10 receives power supply via the power line 110. That is, the power line 110 can perform both information communication and power supply. As described above, the power line 110 includes a two-wire type power line.

The transmission method used in the lighting control system 100 is, for example, a time-division multiplex transmission method as described above, and specifically, a transmission method used in a system such as NMAST (registered trademark). The communication unit 13 transmits information for controlling the load 40 by such a multiplex transmission method, and also receives or transmits at least one or more information of sound, characters, and images by the multiplex transmission method. Do. A method of transmitting information for controlling the load 40 and receiving or transmitting at least one or more information of sound, characters, and images by the same transmission method will be described with reference to FIGS. 5 to 7 described later.

The acquisition unit 14 acquires at least one or more information of sounds, characters, and images. The operation terminal 10 may have, for example, a microphone, and may acquire sound information via the microphone. Further, the operation terminal 10 may have, for example, a camera, and may acquire character or image information via the camera. Further, the operation terminal 10 may be capable of communicating with a mobile terminal such as a smartphone or a tablet, and at least one or more information of sounds, characters and images acquired by the mobile terminal is acquired via the mobile terminal. May be good. The acquisition unit 14 may be realized by a hardware resource such as a microphone or a camera, or may be realized by a program (software).

The conversion unit 15 converts the information acquired by the acquisition unit 14. For example, the conversion unit 15 converts the information acquired by the acquisition unit 14 into information for controlling the load 40. Specifically, when the information acquired by the acquisition unit 14 is a voice meaning that the lighting device is turned on, the conversion unit 15 indicates that the voice turns on the lighting device by voice recognition. Recognizing this, the information acquired by the acquisition unit 14 is converted into information for turning on the lighting device. Further, the conversion unit 15 may convert the information acquired by the acquisition unit 14, for example, into information for setting the lighting control system 100. Specifically, when the information acquired by the acquisition unit 14 is an image for setting the scene control of the lighting device, the conversion unit 15 sets the setting contents for the scene control indicated by the image by image recognition or the like. Is recognized, and the information acquired by the acquisition unit 14 is converted into information for making settings for scene control. The image may be a QR code (registered trademark), and the conversion unit 15 may recognize the content indicated by the QR code (registered trademark). Then, the communication unit 13 transmits the information converted by the conversion unit 15 by the same transmission method as the transmission of information for controlling the load 40 and the reception or transmission of at least one or more information of sound, characters, and images. To do. The communication unit 13 may transmit at least one or more pieces of information such as sounds, characters, and images before conversion.

The first display unit 16 is different from the notification unit 12, and has a configuration in which display is performed based on an operation on the operation unit 11. As shown in FIG. 3, for example, a light emitting unit that emits light by an LED or the like. Is. For example, when the lighting device is turned on and off by operating the operation unit 11, when the lighting device is turned on, the first display unit 16 (LED) that emits a specific color (for example, green) is turned on, and the lighting device is turned on. When turned off, the first display unit 16 (LED) that emits a specific color (for example, red) is turned on. The first display unit 16 is also provided in a conventional operation terminal (wall switch or the like).

[motion]
Next, the operation of the operation terminal 10 will be described with reference to FIG.

FIG. 4 is a flowchart showing an example of the operation of the operation terminal 10 according to the embodiment.

First, the operation unit 11 receives an operation for controlling the load 40 including the lighting device (step S11). For example, the operation unit 11 receives an operation for turning on the lighting device from the user.

Next, the communication unit 13 transmits information for controlling the load 40 (step S12). For example, the information is once transmitted from the communication unit 13 to the transmission unit 20 via the power line 110, and the transmission unit 20 transmits information to be controlled according to the information to the wireless AP 30 via the power line 110. The radio AP30 turns on the lighting device according to the received signal.

When the lighting device is turned on, the lighting device or the wireless AP 30 transmits information indicating that the lighting device is turned on to the transmission unit 20 via the power line 110. The transmission unit 20 transmits at least one or more information of a sound, a character, and an image indicating that the lighting device is turned on to the operation terminal 10 via the power line 110. In this way, the communication unit 13 of the operation terminal 10 receives at least one or more information of sounds, characters, and images (step S13). At this time, the transmission of information for controlling the load 40 and the reception of at least one or more information of sound, characters, and images are performed by the same transmission method.

Then, the notification unit 12 notifies at least one or more information of sounds, characters, and images (step S14). For example, the notification unit 12 notifies that the lighting device has been turned on by at least one or more information of sound, characters, and an image. The notification unit 12 may notify not only the state of the lighting device but also other information by sound, characters, and at least one or more information of images. For example, when a predetermined time (for example, 17:00) is reached, image information indicating that the employee will leave the office on time is transmitted from the transmission unit 20 to the operation terminal 10, and as shown in FIG. The image may be displayed by the notification unit 12 (second display unit).

[Transmission method]
Next, a method of transmitting information for controlling the load 40 and receiving or transmitting at least one or more information of sound, characters, and images by the same transmission method will be described with reference to FIGS. 5 to 7. To do.

FIG. 5 is a diagram showing an example of a transmission signal used in the lighting control system 100 according to the embodiment. For example, FIG. 5 shows a transmission signal when only information for controlling the load 40 is transmitted.

For example, in a transmission method used in a system such as NMAST®, the transmission signal is a pause band A, a start signal band B and C, a signal transmission band D for transmitting data, and a reply signal. It consists of a signal reply band E, which is a reception time slot, and end signal bands F and G. This transmission signal is a time-division multiplex signal of multiple poles (± 24V), and data is transmitted by pulse width modulation of a carrier composed of a pulse train. Since such a transmission signal is generally used in a system such as NMAST (registered trademark), detailed description thereof will be omitted.

For example, by superimposing at least one or more information of sound, characters, and images on a transmission signal in which only information for controlling the load 40 is transmitted, information for controlling the load 40 can be transmitted. , Sound, text and image at least one or more pieces of information are received or transmitted by the same transmission method. In the following, two specific examples will be described with reference to FIGS. 6 and 7 regarding a method of superimposing at least one or more information of sounds, characters, and images.

FIG. 6 is a diagram showing an example of a transmission signal in which at least one or more pieces of information such as sound, characters, and images are superimposed.

As shown in FIG. 6, for example, the polarities are not reversed in the rest zone A, the start signal bands B and C, and at least one or more information of sounds, characters and images in the rest zone A, the start signal bands B and C. The packet P indicating is superimposed. Thereby, while avoiding interference between the transmission of information for controlling the load 40 and the reception or transmission of at least one or more information of sound, characters and images, the transmission and reception of these information are transmitted in the same manner on the common power line 110. It can be done at the same time depending on the method.

FIG. 7 is a diagram showing another example of a transmission signal in which at least one or more pieces of information such as sound, characters, and images are superimposed.

For example, the transmission of information for controlling the load 40 and the reception or transmission of at least one or more information of sounds, characters, and images do not necessarily have to be performed at the same time. For example, the data about the information for controlling the load 40 is not transmitted in the signal transmission band D periodically (for example, once every two times), and the sound is sent to the signal transmission band D and the signal reply band E. , A packet P indicating at least one or more pieces of information of characters and images is superimposed. As a result, the timing of transmitting information for controlling the load 40 and the timing of receiving or transmitting at least one or more information of sound, characters, and images are separated, and the transmission and reception of these information is performed on the common power line 110. It can be performed by the same transmission method.

For example, by superimposing the packet P on the transmission signal, the transmission amount can be increased up to 40 times.

[Modification example]
In the above description, the notification unit 12 includes a second display unit that displays at least one or more information of characters and images, but may include a sound output unit that outputs sound information. This will be described with reference to FIG.

FIG. 8 is an external front view showing another example of the operation terminal 10 according to the embodiment.

As shown in FIG. 8, the notification unit 12 may include, for example, a speaker as a sound output unit. For example, when the lighting device is turned off, the notification unit 12 notifies (audio output) information such as "turning off". For example, when the communication unit 13 receives the sound information or the acquisition unit 14 acquires the information, the notification unit 12 notifies the information.

[Effects, etc.]
As described above, the operation terminal 10 communicates with the operation unit 11 that receives an operation for controlling the load 40 including the lighting device, and the notification unit 12 that notifies at least one or more information of sounds, characters, and images. It has a part 13. The communication unit 13 transmits information for controlling the load 40 and receives or transmits at least one or more information of sound, characters, and images by the same transmission method.

According to this, since the transmission of information for controlling the load 40 and the reception or transmission of at least one or more information of sound, characters and images are performed by the same transmission method, the transmission and reception of these information are common. This can be done on the power line 110. That is, for example, when adding a function using at least one or more information of sounds, characters, and images to a lighting control system having a function for controlling a load 40 already installed in a facility or the like. It is not necessary to provide wiring for communication of at least one or more information of sound, characters, and images separately from wiring for communication of information for controlling the load 40, and the entire lighting control system 100 becomes large and large. It is possible to prevent the cost from increasing. As described above, in the lighting control system 100, it is possible to easily add a function using at least one or more information of sound, characters, and images.

For example, in the lighting control system 100, the operation terminal 10 having a function for controlling the load 40 and a function using at least one or more information of sounds, characters, and images, and a function for controlling the load 40 are It is possible to coexist with an operation terminal which has, but does not have a function using at least one or more information of sounds, characters, and images. Therefore, in the lighting control system 100, it is possible to gradually replace the existing operation terminal with the multifunctional operation terminal 10.

Further, the operation terminal 10 further includes an acquisition unit 14 for acquiring at least one or more information of sounds, characters, and images, and a conversion unit 15 for converting the information acquired by the acquisition unit 14, and the communication unit 13 May transmit the information converted by the conversion unit 15 by the above transmission method.

At least one or more pieces of information such as sound, characters, and images need not be converted in, for example, the transmission unit 20, but are converted into a desired format in the operation terminal 10 as in this embodiment (for example, the load 40 is controlled). (Converted to information for) and transmitted to the load 40.

Further, the operation terminal 10 may further have a first display unit 16 which is different from the notification unit 12 and displays based on the operation on the operation unit 11.

According to this, it is possible to confirm what kind of operation has been performed on the operation unit 11 by the display of the first display unit 16. Further, in the present invention, since the operation terminal 10 also has the notification unit 12 in addition to the first display unit 16, not only the display based on the operation on the operation unit 11 but also the sound, characters, and images are displayed by the notification unit 12. At least one or more pieces of information can be notified.

Further, the communication unit 13 communicates via the power line 110, and the operation terminal 10 may receive power supply via the power line 110.

According to this, power supply and information transmission / reception can be performed by a common power line 110.

Further, the power line 110 may include a two-wire type power line.

According to this, for example, the wiring for connecting the load 40 and the operation terminal 10 on a one-to-one basis becomes unnecessary, and the wiring in the lighting control system 100 can be reduced.

In addition, the notification unit 12 may include a second display unit that displays at least one or more information of characters and images.

According to this, at least one or more information of characters and images can be notified by display.

Further, the notification unit 12 may include a sound output unit that outputs sound information.

According to this, sound information can be notified by sound output.

Further, for example, in the above embodiment, the communication unit 13 communicates via the power line 110, but it does not have to communicate via the power line 110. For example, the communication unit 13 may communicate via a communication line or the like that is not used for supplying electric power.

Further, for example, in the above embodiment, the transmission method is a transmission method used in a system such as NMAST (registered trademark), but transmission of information for controlling the load 40 and sound, characters, and images It is not limited to such a transmission system as long as it is possible to receive or transmit at least one or more of the information by the same transmission system.
