  By the way, a DMX signal is often used as a dimming signal. The DMX signal is a digital signal used in a production field or the like standardized by the American Theater Technology Association (USITT), and indicates the DMX 512 used as a standard of a dimming signal for dimming control. The DMX 512 is a signal having a configuration in which 512 channels each composed of 8 bits each sandwiched between a start bit and a stop bit are multiplexed into one frame, and one predetermined channel in the 512 channels is one adjustment. A dimming signal of 256 gradations (8 bits) for performing dimming control to the optical device. The start of one frame is detected by detecting a break (BREAK) and a start code. Further, the channel corresponding to the dimmer included in each dimming device counts and detects how many channels sandwiched between the start bit and the stop bit have arrived from the start of the frame.

  A system for receiving the above DMX signal from the operation unit and sending it to the light control device side by radio is configured as shown in FIG. 9, for example. A lighting device fixture 201 called a baton suspended from the ceiling is installed with fixtures A, B and C including a dimmer and a lighting load, and a lighting device fixture 202 includes a dimmer and a lighting load.

In addition, a wireless receiver 204 is installed in the lighting equipment fixture 201, and a DMX signal is transmitted from the wireless receiver 204 to the devices A, B, and C. A wireless receiver 205 is installed in the lighting device fixture 202, and a DMX signal is transmitted from the wireless receiver 205 to the appliances D, E, and F.

  Further, the DMX signal is sent from the controller 101 to the wireless transmitter 102, and the DMX signal is transmitted from the wireless transmitter 102 to the wireless receivers 204 and 205 by radio. In this case, if valid addresses (channel numbers) that can be transmitted from the operation device 101 are channels “1, 2, 3”, the addresses of the devices A, B, C and the devices D, E, F are shown in FIG. It is necessary to set the channels “1, 2, 3” as indicated by the circle in FIG.

  However, when the addresses of the appliances D, E, and F are set (fixed) to the channels “4, 5, and 6”, the appliances D, E, and F have the channels “4, 5 and 5” corresponding to the fixed addresses. , 6 ", the dimming level of the DMX signal corresponding to the channels" 1, 2, 3 "is also controlled for the appliances D, E, and F, for example. Can not do.

  On the other hand, a shift device that shifts the address of the DMX signal is also interposed between the operation device 101 and the wireless transmitter 102, but the shift device waits for the arrival of the DMX signal for one frame. Further, there is a problem that a delay occurs because the wireless transmitter 102 performs wireless transmission processing after waiting for arrival of a DMX signal for one frame in the wireless transmitter 102.

  The present invention has been made to solve the problems in the conventional dimming system using a radio signal as described above, and its purpose is to perform a necessary shift with respect to the address of the DMX signal output from the controller. It is to provide an illumination system that can be applied to a dimmer and can reduce delay problems. Furthermore, it aims at providing the radio | wireless communication apparatus used for this illumination system.

  The operation device includes a large dimming console and a portable dimming console. The setting means for setting the shift value for shifting the address allows a keyboard type or dial type operation unit, or one connected via a connector. The DMX signal indicates the DMX 512 standardized by USITT described above. The shift means is allowed to be realized by a computer. The object to be controlled is not only the illumination load that is the subject of dimming control, but also the color conversion mechanism of the luminaire and the image control or the operation control of the image projection apparatus when the color conversion speed control by the color conversion film is performed by the DMX signal. And other lighting fixtures that can be controlled by the DMX signal. The illumination control means refers to a dimmer, a lighting fixture control device, and the like.

Since the address of the signal is shifted and the DMX signal of the shifted address is transmitted wirelessly, it can be transmitted to a wireless receiver that shifts the address of the DMX signal by a desired amount. When it is fixed to the back or high place, it is convenient to control the address shift at one place in the ground side radio transmitter. Further, since the wirelessly received signal is shifted and transmitted by wire, the process of waiting for one frame of the DMX signal can be completed at once, and the delay can be suppressed.

And delay can be suppressed.

  Embodiments of an illumination system using a wireless communication apparatus according to embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, the same components are denoted by the same reference numerals and redundant description is omitted. FIG. 1 shows a configuration example of a light control system that is an illumination system according to the first embodiment. In this dimming system, an operation device 10 that outputs a DMX signal, a wireless transmitter 20 that is a wireless communication device that wirelessly transmits the DMX signal output from the operation device 10, and a wireless device that wirelessly receives the DMX signal. The receivers 30 and 30A are main components.

  The DMX signal output from the controller 10 is received by the wired receiver 21 of the wireless transmitter 20 via the signal line 11. The wireless transmitter 20 includes a setting switch 22, a CPU 23, and a wireless transmitter 24 in addition to the wired receiver 21. The setting switch 22 is used to set a shift value for shifting the address of the DMX signal. For example, the setting switch 22 includes a pressing operation type key capable of setting a numerical value from 1 to 512. The set three-digit numerical value is taken into the CPU 23. The CPU 23 controls the radio transmitter 20 in an integrated manner, and functions as a shift means that shifts the address of the DMX signal and sends it to the radio transmitter 24 based on the three-digit numerical value set by the setting switch 22. The wireless transmission unit 24 transmits a given DMX signal wirelessly.

  The wireless receiver 30 is a wireless communication device according to an embodiment of the present invention, and the wireless receiver 30A is a conventional device. The wireless receiver 30 includes a wireless reception unit 31, a setting switch 32, a CPU 33, and a wired transmission unit 34. The wireless reception unit 31 receives a DMX signal transmitted from the wireless transmitter 20.

  The setting switch 32 is for setting a shift value for shifting the address of the DMX signal, and is configured similarly to the setting switch 22. The CPU 33 performs overall control of the wireless receiver 30 and functions as a shift means for shifting the address of the DMX signal based on the numerical value set by the setting switch 32 and sending it to the wired transmission unit 34 for wireless transmission. The DMX signal is sent to the wired transmission unit 34. The wired transmission unit 34 transmits the given DMX signal to the signal line 40 by wire.

  A plurality of (in this case, three) dimmers 41, 42, and 43 are connected to the signal line 40, and take in dimming level information based on the DMX signal of the channel corresponding to the address set to the signal line 40. As described above, the channel corresponding to the address set to itself is detected by counting how many channels between the start bit and the stop bit have arrived from the start of the frame. The dimmers 41, 42, and 43 control the connected illumination loads 51, 52, and 53 so that the corresponding brightness is obtained based on the dimming level information thus captured.

  The wireless receiver 30A includes a wireless reception unit 31A, a CPU 33A, and a wired transmission unit 34A. The radio reception unit 31A receives a DMX signal transmitted from the radio transmitter 20. The CPU 33A performs overall control of the wireless receiver 30A, and sends the DMX signal transmitted from the wireless receiver 31A to the wired transmitter 34A as a DMX signal for wireless transmission. The wired transmission unit 34A transmits the given DMX signal to the signal line 40A by wire.

  A plurality of (in this case, three) dimmers 43, 44, and 45 are connected to the signal line 40A, and take in dimming level information based on the DMX signal of the channel corresponding to the address set to the signal line 40A. As described above, the channel corresponding to the address set to itself is detected by counting how many channels between the start bit and the stop bit have arrived from the start of the frame. The dimmers 44, 45, and 46 control the connected illumination loads 54, 55, and 56 so that the corresponding brightness is obtained based on the dimming level information thus captured.

  In the dimming system configured as described above, for example, by operating the setting switch 22 of the radio transmitter 20 to set a desired shift value, the address of the DMX signal is shifted in the radio transmitter 20. For example, in the operation device 10, the dimming level having the value shown in FIG. 2A is set and output to the channels 1 to 512 of the DMX signal.

  Here, when the shift value is set to “4” by the setting switch 22 of the wireless transmitter 20, the dimming level of the channel 1 is shifted to the channel 4, and the dimming level of the channel 2 is shifted to the channel 5. , The dimming level of channel 3 is shifted to channel 6,..., The dimming level of channel 509 is shifted to channel 512 (FIG. 2B).

  The dimming levels of the original channels 510 to 512 are discarded, and the dimming level 0 is set to the shifted channels 1 to 3 (FIG. 2B). However, the CPU 23 may be configured to include the rotation function as the shift function, and the dimming level of the original channels 510 to 512 may be set to the shifted channels 1 to 3.

  As for the DMX signal whose address is shifted by the wireless transmitter 20 as described above, the dimming level is transmitted from the wireless transmission unit 24 as shown in FIG. 2C and received by the wireless receiver 30 (30A). The Assuming that the setting value of the setting switch 32 is set to 1 in the wireless receiver 30, the signal is transmitted to the signal line 40 (40A) as a DMX signal as shown in FIG.

  In such a wireless transmitter 20, when the shift value of the setting switch 22 is set to 4 and the address is shifted and used, the devices (the dimmer and the illumination) connected to the wireless receivers 30A and 30A as shown in FIG. (Including load) When the addresses of A and D are 4, the addresses of devices B and E are 5, and the addresses of devices C and F are 6, the outputs corresponding to the channels 1, 2, and 3 are output from the controller 10. Light levels can be given to devices A and D, devices B and E, and devices C and F, respectively.

  If the addresses of devices A, B, and C are 4, 5, and 6, and the addresses of devices D, E, and F are 7, 8, and 9, two wireless transmissions are performed as shown in FIG. Machines 20 and 20 are used. In the wireless transmitter 20 that transmits to the wireless receiver 30A connected to the devices A, B, and C, the shift value is set to “4” by the setting switch 22, and the wireless receiver connected to the devices D, E, and F is set. In the wireless transmitter 20 that performs transmission to 30A, the shift value is set to “7” by the setting switch 22. Thereby, in the output of the operation device 10, the dimming levels corresponding to the channels 1, 2, and 3 are the devices A, B, and C whose addresses are 4, 5, and 6 and the devices whose addresses are 7, 8, and 9, respectively. D, E, and F can be given respectively.

  In FIG. 1, for example, by operating the setting switch 32 of the wireless receiver 30 to set a desired shift value, the address of the DMX signal is shifted in the wireless receiver 30. Here, it is assumed that the setting switch 22 of the wireless transmitter 20 has a shift value of 1 and no shift is performed. For example, in the operation device 10, the dimming level of the value shown in FIG. 5A is set and output to the channels 1 to 512 of the DMX signal.

  Here, since the shift value is set to “1” by the setting switch 22 of the wireless transmitter 20, the address is not shifted by the wireless transmitter 20, and the DMX signal is as shown in FIG. There is no change from the beginning, and the dimming level is transmitted from the wireless transmitter 20 as shown in FIG.

  In response, the shift value is set to “4” by the setting switch 32 of the wireless receiver 30, so that the dimming level of channel 1 is shifted to channel 4 and the dimming level of channel 2 is shifted to channel 5. Then, the dimming level of channel 3 is shifted to channel 6,..., The dimming level of channel 509 is shifted to channel 512 (FIG. 5D).

  The dimming levels of the original channels 510 to 512 are discarded, and the dimming level 0 is set to the shifted channels 1 to 3 (FIG. 5D). However, the CPU 33 may be configured to include the rotation function as the shift function, and the dimming level of the original channels 510 to 512 may be set to the shifted channels 1 to 3.

  As described above, the DMX signal whose address is shifted by the wireless receiver 30 is transmitted to the signal line 40 as a DMX signal as shown in FIG. The DMX signal that passes through the wireless receiver 30 that does not have the shift function is sent to the signal line 40 while maintaining the correspondence between the address of the DMX signal output from the operation unit 10 and the dimming level as shown in FIG. Is done.

  As shown in FIG. 7, such wireless receivers 30 and 30 are connected to devices A, B, and C and devices D, E, and F, and the setting switches 32 and 32 of the wireless receivers 30 and 30 are connected together. When the address is shifted as 4, and the addresses of the devices A and D are 4, the addresses of the devices B and E are 5, and the addresses of the devices C and F are 6, 3 can be given to the devices A and D, the devices B and E, and the devices C and F.

  Further, when the addresses of the devices A, B, and C are 4, 5, and 6, and the addresses of the devices D, E, and F are 7, 8, and 9, the devices A, B, The setting switch 32 of the wireless receiver 30 connected to C is set to 4, and the setting switch 32 of the wireless receiver 30 connected to the devices D, E, and F is set to 7. The controller 10 is connected to a radio transmitter 20A that does not have the DMX signal address shift function to perform transmission. Thereby, in the output of the operation device 10, the dimming levels corresponding to the channels 1, 2, and 3 are the devices A, B, and C whose addresses are 4, 5, and 6 and the devices whose addresses are 7, 8, and 9, respectively. D, E, and F can be given respectively. That is, it is possible to deal with a device in which a different address is set (fixed) by changing an address shift value for each of the plurality of wireless receivers 30, 30,.

  As shown in FIG. 1, when the wireless transmitter 20 includes the setting switch 22 and the wireless receiver 30 includes the setting switch 32, both the wireless transmitter 20 and the wireless receiver 30 address the DMX signal. It is also possible to use it after shifting.
