The present invention relates to an interlocking selector for dimming to be switched, and a dimming system using the same.

  FIG. 6 shows the configuration of a dimming system using a conventional dimming interlocking selector (hereinafter referred to as an interlocking selector) 9. The interlocking selector 9, dimmers 8a and 8b, and external operation are shown. The device 3 is connected to the same transmission line L, and the lighting devices 4a and 4b are connected to the light control devices 8a and 8b, respectively. The interlocking selector 9 includes an operation selecting means that can select either an interlocking operation that causes the dimmers 8a and 8b to operate in conjunction with each other or an unlinked operation that causes the dimmers 8a and 8b to operate independently. When the interlocking operation is selected, the interlocking signal is output to the transmission line L. When the interlocking operation is selected, the interlocking signal is output to the transmission line L.

  The dimmers 8a and 8b control the dimming of the connected lighting fixtures 4a and 4b. The dimmers 8a and 8b monitor the selection state of the interlock selector 9 by using interlocking signals and non-interlocking signals received via the transmission line L. The operation of the light control devices 8a and 8b is switched to a linked operation or a non-linked operation depending on the selection state of the linkage selector. Specifically, when the interlocking operation is selected by the interlocking selector 9 and the dimming devices 8a and 8b receive the interlocking signal, the instruction from the external operation device 3 or the operation unit provided in the own device is received. The dimmer 8a performs dimming control of the luminaire 4a, and directly transmits a scene reproduction signal to be reproduced to the dimming degree of a desired scene to the dimmer 8b via the transmission line L. The dimming device 8b reproduces the lighting fixture 8b to a predetermined dimming degree based on the received scene reproduction signal, and when the reproduction to the predetermined dimming degree is completed, a completion signal is sent to the dimming device 8a via the transmission line L. Send directly to tell you that dimming playback is complete. When the non-interlocking operation is selected by the interlocking selector 9, and the dimmers 8a and 8b receive the non-interlocking signal, the dimmers 8a and 8b individually perform dimming control of the lighting fixtures 4a and 4b. .

  The dimming devices 8a and 8b and the interlocking selector 9 are provided with address setting means for setting their own addresses, and individually assign different addresses. The linked operation is realized by software stored in each of the light control devices 8a and 8b, and the operation is managed by each set address.

Further, in the signal transmission method using the transmission line as described above, the communication traffic is reduced by setting whether to allow or forbid the return of the reception confirmation signal when the signal is received. There is a way to reduce it. (For example, see Patent Document 1)

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 2 shows the configuration of a dimming system using a dimming interlock selector (hereinafter referred to as an interlock selector) according to the present embodiment. The dimming system includes two interlock selectors 1a and 1b. Two lines of transmission lines La and Lb are connected to the device 1a, and two lines of transmission lines Lb and Lc are connected to the interlocking selector 1b. That is, the interlock selector 1a is interposed between the transmission lines La and Lb, and the interlock selector 1b is interposed between the transmission lines Lb and Lc. The light control device 2a and the external operation device 3 are connected on the transmission line La, the light control device 2b is connected on the transmission line Lb, and the light control device 2c is connected on the transmission line Lc. The lighting devices 4a, 4b and 4c are connected to the light control devices 2a, 2b and 2c, respectively.

  The interlock selector 1 (having the same configuration as the interlock selectors 1a and 1b) has an operation selection means 10, two transmission means 11 and 11, and an address setting means 12 as shown in a block configuration in FIG. And control means 13 (corresponding to address adding means and transmission control means). The operation selecting means 10 is composed of a switch, a push button, a touch panel, or the like, and operates in conjunction with each operation of the dimmers on the two transmission lines L connected to the own device. It has a function capable of selecting either a non-interlocking operation in which each dimming device on two connected transmission lines L is operated independently. The transmission means 11, 11 is composed of an IC for serial communication, a driver IC, and the like, and transmits and receives signals to and from devices such as a light control device via two transmission lines L connected to the own device. . The address setting means 12 is composed of a dip switch or the like, and sets its own address. This address is assigned to a different address for each interlocking selector. The control means 13 is constituted by an MPU or the like, and controls each operation of the operation selection means 10, transmission means 11 and 11, and address setting means 12 based on software stored in the control means 13.

  FIGS. 3A and 3B are a front view and a side view of the interlock selector 1, and FIG. 4 is a back view of the interlock selector 1. The main body 16 of the interlocking selector 1 is formed in a substantially box shape. On the front side of the main body 16, a switch 10a for selecting the interlocking operation and a switch 10b for selecting the non-interlocking operation are provided as the operation selecting means 10. The switches 10a and 10b are exposed from the front center of the substantially rectangular plate 14 attached to the front side of the main body 16. Further, two sets of terminal blocks 15 and 15 for connecting two systems of transmission lines L are provided on the back surface of the main body 16, and the terminal blocks 15 and 15 are connected to the control means 13 through the transmission means 11 and 11, respectively. Has been. Further, the address setting means 12 constituted by a dip switch is disposed on the front side of the main body 16 and exposed to the front side when the plate 14 is removed (see FIG. 3A). Alternatively, the address setting means 12 may be disposed on the side surface of the main body 16 (see FIG. 3B).

  Next, the operation by software stored in the control means 13 of the interlock selector 1 will be described. First, the control means 13 of the interlock selector 1 monitors the state of the switches 10a and 10b of the input means 10. When the switch 10a is operated and the interlocking operation is selected, the control unit 13 monitors signals received by the transmission units 11 and 11 via the transmission line L. Then, when an instruction signal giving an operation instruction is transmitted from the dimmer on one transmission line L to the other dimmer, and one of the transmission means 11 of the interlocking selector 1 receives this instruction signal, the control means 13 operates as an address adding means, adds the address of the own device preset by the address setting means 12 to the received instruction signal, relays the instruction signal with the address of the own device, and transmits the other transmission means 11. To the light control device on the other transmission line L. The control means 13 also operates as a transmission control means when receiving the instruction signal, analyzes the address added to the instruction signal received by the transmission means 11, and if the address of its own device is added. The instruction signal is judged to be an instruction signal transmitted by itself, and the instruction signal is not relayed or transmitted. When the button 10b of the interlock selector 1 is operated and the non-interlock operation is selected, the control means 13 does not relay or transmit all signals received by the transmission means 11 and 11 via the transmission line L. Each dimmer is operated independently. The instruction signal is an adjustment signal for adjusting the dimming degree, a storage signal for storing the current dimming degree, a scene reproduction signal for reproducing the dimming degree of a desired scene, and the like.

  For example, in the communication system shown in FIG. 2, when the interlock selector 1a selects the interlock operation, the dimmer 2a receives an instruction from the external operation device 3 or an instruction from the operation unit provided in the own device. When the scene reproduction signal is transmitted through the transmission line La, in the interlock selector 1a, the control unit 13 analyzes the address of the scene reproduction signal received by the transmission unit 11 from the dimmer 2a through the transmission line La. . In this case, since the address is not added to the received scene playback signal, the control means 13 of the interlock selector 1a adds the address of the interlock selector 1a preset by the address setting means 12 to the received scene playback signal. Then, the scene reproduction signal to which the address of the interlock selector 1a is added is relayed and transmitted from the transmission means 11 to the dimming device 2b via the transmission line Lb.

  The dimming device 2b that has received the scene reproduction signal to which the address of the interlocking selector 1a has been added reproduces the luminaire 4b to a predetermined dimming degree, and at the same time receives the scene reproduction signal to which the address of the interlocking selector 1a has been added. , 1b via the transmission line Lb.

  In the interlock selector 1b that has received the scene playback signal to which the address of the interlock selector 1a is added from the dimmer 2b, when the interlock operation is selected, the address of the scene playback signal received by the transmission means 11 is controlled by the control means 13. Analyzes. In this case, since the address of the interlocking selector 1a different from the interlocking selector 1b is added to the received scene playback signal, the control means 13 of the interlocking selector 1b adds the address of the interlocking selector 1b to the received scene playback signal. The scene reproduction signal to which the address of the interlocking selector 1b is added is relayed and transmitted from the transmission means 11 to the dimmer 2c via the transmission line Lc. The dimming device 2c that has received the scene reproduction signal to which the address of the interlocking selector 1b has been added reproduces the luminaire 4c to a predetermined dimming degree. When the interlock selector 1b selects the non-interlock operation, the interlock selector 1b does not relay or transmit the scene reproduction signal, but operates the dimmer 2c alone.

  On the other hand, in the interlock selector 1a that has received the scene playback signal to which the address of the interlock selector 1a is added from the light control device 2b, the control means 13 analyzes the address of the scene playback signal received by the transmission means 11. In this case, since the address of the interlock selector 1a is added to the received scene reproduction signal, the control means 13 of the interlock selector 1a determines that the instruction signal is transmitted by itself and determines the interlock selector 1a. Does not relay or transmit the scene reproduction signal to the light control device 2a and the external operation device 3. That is, the useless signal is prevented from being transmitted from the interlocking selector 1a.

  In addition, the dimmer 2b regenerates the lighting fixture 4b to a predetermined dimming degree, and then notifies the external peripheral device such as the dimmer 2a and the external operation device 3 that the reproduction of dimming is completed. Is transmitted via the transmission line Lb. The interlocking selector 1a that has received the completion signal transmits this completion signal to the dimming device 2a and the external peripheral device via the transmission line La, thereby notifying that the lighting fixture 4b has been reproduced to a predetermined dimming degree. Similarly, the luminaire 4c transmits a completion signal.

  As described above, the interlock selector 1 includes a transmission unit 11 that exchanges signals with other devices on the transmission line L, and a control unit 13 that adds and analyzes an address to a signal to be relayed. Without being restricted by address setting management by the software of the optical device, a plurality of devices can be connected on the transmission line L to perform the linked operation / non-linked operation of each dimming device.

(Embodiment 2)
FIG. 5 shows the configuration of a dimming system using four interlocking selectors 1a to 1d similar to the first embodiment. Two interlocking transmission lines La and Lb are connected to the interlocking selector 1a. Two lines of transmission lines Lb and Lc are connected to the selector 1b, two lines of transmission lines Lb and Ld are connected to the interlocking selector 1c, and two lines of transmission lines Ld and Le are connected to the interlocking selector 1d. It is connected. That is, the interlock selector 1a is inserted between the transmission lines La and Lb, the interlock selector 1b is inserted between the transmission lines Lb and Lc, the interlock selector 1c is inserted between the transmission lines Lb and Ld, The interlock selector 1d is inserted between the transmission lines Ld and Le. The light control device 2a is connected to the transmission line La, the light control device 2b is connected to the transmission line Lb, the light control device 2c is connected to the transmission line Lc, and the transmission line Ld is connected to the transmission line Ld. The light control device 2d is connected, the light control device 2e is connected on the transmission line Le, and the lighting fixtures 4a to 4e are connected to the light control devices 2a to 2e, respectively.

  In the present embodiment, a case will be described in which three interlocking selectors 1a, 1b, and 1c are connected to the light control device 2b, and the interlocking operations are all selected in the interlocking selectors 1a to 1d. First, when a scene reproduction signal is transmitted via the transmission line La from the dimming device 2a that has received an instruction for the interlock operation, the interlock selector 1a analyzes the address of the scene reproduction signal received via the transmission line La. In this case, since the address is not added to the received scene playback signal, the scene playback is performed by adding the address of the interlocking selector 1a set in advance to the received scene playback signal and adding the address of the interlocking selector 1a. The signal is transmitted to the dimmer 2b via the transmission line Lb.

  The dimming device 2b that has received the scene reproduction signal to which the address of the interlocking selector 1a has been added reproduces the lighting fixture 4b to a predetermined dimming degree, and at the same time the scene reproduction signal to which the address of the interlocking selector 1a has been added. , 1b, 1c through the transmission line Lb.

  The link selector 1b, which has received the scene playback signal to which the address of the link selector 1a is added from the dimmer 2b, analyzes the address of the scene playback signal received via the transmission line Lb. Since the address of the link selector 1a different from the link selector 1b is added to the signal, the link selector 1b adds the address of the link selector 1b to the received scene reproduction signal, and the link of the link selector 1b. The scene reproduction signal to which the address is added is transmitted to the dimmer 2c via the transmission line Lc, and the dimmer 2c reproduces the lighting fixture 4c to a predetermined dimming degree.

  Similarly to the dimming selector 1b, the interlock selector 1c also adds the address of the interlock selector 1c to the received scene playback signal, and transmits the scene playback signal with the address of the interlock selector 1c to the dimmer 2d. The light control device 2d regenerates the lighting fixture 4d to a predetermined light control level.

  However, in the interlock selector 1a that has received the scene playback signal to which the address of the interlock selector 1a is added from the dimming device 2b, the address of the received scene playback signal is analyzed. In this case, the received scene playback signal is interlocked with the scene playback signal. Since the address of the selector 1a is added, the interlock selector 1a determines that it is an instruction signal transmitted by itself, and does not relay or transmit the scene reproduction signal to the dimmer 2a. That is, the useless signal is prevented from being transmitted from the interlocking selector 1a.

  Furthermore, the interlock selector 1d adds the address of the interlock selector 1d to the scene playback signal received from the dimmer 2d, and transmits the transmission line Le to the dimmer 2e of the scene playback signal to which the address of the interlock selector 1c is added. The light control device 2e regenerates the lighting fixture 4e to a predetermined light control level.

  In addition, the dimmers 2a to 2e regenerate the lighting fixtures 4a to 4e respectively to a predetermined dimming degree, and then notify the other dimmers and external peripheral devices that the dimming reproduction has been completed. Are transmitted via the transmission lines La to Le to notify that the lighting fixtures 4a to 4e have been regenerated to a predetermined dimming degree.

  As described above, as in the first embodiment, the interlock selector 1 exchanges signals with other devices on the transmission line L, adds addresses to the relayed signals, and analyzes them. Without being restricted by address setting management by the software, it is possible to connect a plurality of devices on the transmission line L and perform the linked operation / non-linked operation of each dimming device.
