  FIG. 1 is a diagram showing a configuration of an illumination control system having a dimming data recording / reproducing apparatus according to the present embodiment.

  As shown in FIG. 1, the lighting control system 1 includes a dimming control device 2 disposed in an indoor facility such as a hall or a theater, and a dimming signal recording and reproducing the dimming signal generated by the dimming control device 2. The optical data recording / reproducing apparatus 3 and a dimming panel 4 for receiving a dimming signal reproduced by the dimming data recording / reproducing apparatus 3 are configured.

The light control board 12 includes a transmission receiver 13 having a recording device 14 and a plurality of PWM light adjusters 15a to 15e in the present embodiment.

  The dimming data recording / reproducing apparatus 3 includes an operation unit 21, a plurality of, in the present embodiment, five PWM receiving units 22a to 22e, a PWM dimming level measuring unit 24, a clock unit 25, and a dimming level storage. Unit 26 and a DMX output unit 27.

  In addition, the light control panel 4 includes a transmission / reception unit 31 and a plurality of PWM light adjusters 32a to 32e in the present embodiment.

  The lighting control system 1 of the present embodiment is configured to include five lighting loads 17a to 17e, but the number of lighting loads 17a to 17e is not limited to five, for example, You may have four or less, or six or more. In addition, the number of PWM dimmers 15a to 15e, switches 16a to 16e, PWM receivers 22a to 22e, and PWM dimmers 32a to 32e are changed with the number of illumination loads 17a to 17e.

  The dimming controller 11 is an operating unit for operating the illumination loads 17a to 17e to a dimming state with a desired brightness, and a dimming operation signal corresponding to the operation of the operator is transmitted and received by the dimming panel 12 13 is transmitted. The dimming operation signal from the dimming controller 11 is transmitted to the transmission receiving unit 13 of the dimmer 12 as a DMX signal, for example.

  The transmission receiving unit 13 includes a recording device 14 and can record the received dimming operation signal in the recording device 14. In addition, the transmission receiver 13 supplies the received dimming operation signal to the PWM dimmers 15a to 15e.

  The PWM dimmers 15a to 15e generate dimming signals to be supplied to the illumination loads 17a to 17e based on the dimming operation signals from the dimming operation unit 11, respectively. The dimming signals generated by the PWM dimmers 15a to 15e are output from the PWM dimmers 15a to 15e as PWM signals having different duty ratios determined according to the dimming rates, respectively.

  The PWM signals output from the PWM dimmers 15a to 15e are supplied to one terminals of the switches 16a to 16e, respectively. Further, the PWM signals output from the PWM dimmers 32a to 32e are supplied to the other terminals of the switches 16a to 16e. In FIG. 1, the PWM signal from the PWM dimmer 32a is supplied only to the switch 16a, but the PWM signals from the PWM dimmers 32b to 32e are similarly supplied to the switches 16b to 16e, respectively.

  The switches 16a to 16e select the PWM signals output from the PWM dimmers 15a to 15e or the PWM dimmers 32a to 32e based on the switching signal from the operation unit 21, respectively, and the illumination loads 17a to 17e. Output to.

  The lighting loads 17a to 17e are, for example, LED (Light Emitting Diode) lighting fixtures or FL (Fluorescent Lamp) lighting fixtures, and the like, depending on the PWM signals from the PWM dimmers 15a to 15e or the PWM dimmers 32a to 32e. Illuminate with high brightness.

  The dimming data recording / reproducing apparatus 3 is configured to be detachable from the dimming control apparatus 2. In FIG. 1, for the sake of simplicity, the PWM receivers 22a to 22e are described as being connected to the signal lines of the PWM dimmers 15a to 15e, respectively. The PWM dimmers 15a to 15e are detachably connected.

  The operation unit 21 is an operation unit for instructing recording and reproduction of dimming data according to dimming signals from the PWM dimmers 15a to 15e according to an operation of the operator. In addition, the operation unit 21 outputs a switching signal to the switches 16a to 16e as described above according to the operation of the operator.

  The PWM receivers 22a to 22e receive the PWM signals from the PWM dimmers 15a to 15e, respectively, when the start of recording of the dimming data is instructed by the operation of the operation unit 21. The PWM receivers 22a to 22e output the received PWM signals to the PWM dimming level measuring unit 23, respectively. In the following description, the PWM signals input to the PWM receivers 22a to 22e are referred to as input PWM signals P1 to P5, respectively.

  The PWM dimming level measurement unit 23 samples the input PWM signals P1 to P5 at predetermined intervals and measures the dimming level. The PWM dimming level measurement unit 23 outputs the measured dimming levels of the input PWM signals P <b> 1 to P <b> 5 to the control unit 24.

  Current time information is supplied from the clock unit 25 to the control unit 24. The control unit 24 adds the time from the clock unit 25 to the input dimming level as a time stamp, and stores it in the dimming level storage unit 26. The dimming data recording process will be described in detail with reference to FIGS. 2 and 3 to be described later.

  When the control unit 24 is instructed to reproduce the dimming data stored by the operation unit 21, the control unit 24 reads the corresponding dimming data stored in the dimming level storage unit 26 and supplies it to the DMX output unit 27. In this embodiment, there are two types of dimming data reproduction processing: time code reproduction and scene single reproduction. The dimming data reproduction process will be described in detail with reference to FIGS. 4 and 5 to be described later.

  The DMX output generates a DMX signal corresponding to the input dimming data and outputs it to the transmission receiving unit 31 of the dimming board 4. The transmission receiver 31 outputs the received DMX signal to the PWM dimmers 32a to 32e.

  The PWM dimmers 32a to 32e generate dimming signals corresponding to the inputted DMX signals, here, PWM signals, and output them to the switches 16a to 16e.

Here, the dimming data recording process will be described.
FIG. 2 is a diagram for explaining an example of measuring the light control level. In FIG. 2, only the input PWM signals P1 and P2 are described for the sake of simplicity, but the same processing is performed for the input PWM signals P3 to P5.

  As shown in FIG. 2, the start of recording of the light control data is instructed by the operation unit 21 at 11: 23: 59.9 seconds in the time of the clock unit 25, and 11: 24: 55.8 in the time of the clock unit 25 Assume that the end of recording of the light control data is instructed by the operation unit 21 per second.

  The PWM dimming level measurement unit 23 measures the communication cycle of the PWM signal, for example, every second from 11: 23: 59.9 seconds, as indicated by bold arrows. Note that the first cycle instructed to start the recording of the light control data is the first cycle.

  The PWM dimming level measurement unit 23 samples ON or OFF of the signal levels of the input PWM signals P1 and P2 every 1 msec. In the present embodiment, the signal level is H level ON and the signal level is L level OFF. For simplicity of explanation, the sampling period is described as 1 msec. However, for example, sampling is executed at a high-speed period such as 1 μsec.

  The PWM dimming level measurement unit 23 measures the dimming level as 50% by measuring five ONs and five OFFs in the first period of the input PWM signal P1. The PWM dimming level measurement unit 23 measures the dimming level as 10% by measuring one ON and nine OFFs in the first period of the input PWM signal P2. Similar processing is executed for each communication cycle, and the dimming level is sequentially measured as 50%, 60%, 80%, 80%, 100%, and 0% from the input PWM signal P1. Further, from the input PWM signal P2, the dimming level is sequentially measured as 10%, 20%, 30%, 40%, 50% and 60%. The dimming data thus measured is stored in the dimming level storage unit 26.

  FIG. 3 is a diagram for explaining an example of dimming data stored in the dimming level storage unit. In addition, although description is abbreviate | omitted, the dimming level is similarly preserve | saved also about input PWM signal P3-P5.

  The control unit 24 adds the time measured by the clock unit 25 as a time stamp to the dimming level measured as shown in FIG. 2 by the PWM dimming level measuring unit 23 and stores it. For example, 11: 23: 59.9 seconds at which measurement is started is added as a time stamp to the dimming level (50% and 10%, respectively) of the first period of the input PWM signals P1 and P2. In the following description, the dimming data stored as shown in FIG.

  Further, as shown in FIG. 3, the control unit 24 stores the measured dimming level in time series. For example, the control unit 24 may store the dimming level of only one shot scene. Good.

  Next, a process for reproducing the light control data will be described. First, time code reproduction will be described with reference to FIG.

  FIG. 4 is a diagram for explaining time code reproduction processing. In FIG. 4, channels CH1 and CH2 correspond to the dimming data of the input PWM signals P1 and P2, respectively. The same applies to FIG. 5 described later.

  As shown in FIG. 1, the control unit 24 is supplied with an external time code from an external clock (not shown). When the operator uses the operation unit 21 to instruct the start of time code reproduction, the control unit 24 monitors the time code from the clock unit 25 or the external time code from the external clock. The control unit 24 determines whether the time code from the clock unit 25 or the external time code from the external clock matches the time stamp of the dimming data stored in the dimming level storage unit 26. If the control unit 24 determines that they match, the control unit 24 reads out the corresponding dimming data and outputs it to the DMX output unit 27. For example, when it is determined that the time code from the clock unit 25 matches the time stamp of the stored light control data, the scene can be played back at a time determined every day. On the other hand, when it is determined that the external time code from the external clock matches the time stamp of the stored dimming data, it is possible to perform scene playback in conjunction with other devices (such as sound and video).

  In the time code reproduction, for example, as shown in FIG. 4, when the time code from the clock unit 25 or the external time code from the external clock reaches 11: 23: 59.9 seconds, the control unit 24 reproduces the corresponding dimming data. That is, playback of the scene A shown in FIG. 3 is started. Note that after 11: 24: 55.9 seconds, the dimming level of the final cycle, here, the dimming level of the sixth cycle is held.

Next, scene single reproduction will be described.
FIG. 5 is a diagram for explaining the process of scene single reproduction.

  The dimming level storage unit 26 stores a plurality of scenes in addition to the scene A of FIG. When the operator selects a scene to be reproduced from a plurality of scenes by using the operation unit 21 and instructs the start of the reproduction, the control unit 24 reads the selected scene, that is, the dimming level. The data is output to the DMX output unit 27.

  When the playback of the scene A is instructed in the scene independent playback, the control unit 24 starts the playback of the scene A with the time when the start of the playback is instructed as 0 seconds, for example, as shown in FIG. Note that after 6 seconds, the light control level of the final cycle, here, the light control level of the sixth cycle is held.

  The control unit 24 outputs the read scene, that is, the dimming level, to the DMX output unit 27. However, the read dimming level data is directly input to the PWM dimmer 32a via, for example, an interface. To 35e may be output. In this case, the DMX output unit 27 and the transmission / reception unit 31 are replaced with interfaces. The PWM dimmers 32a to 35e generate a PWM signal corresponding to the input dimming level and output the PWM signal to the illumination loads 17a to 17e via the switches 16a to 16e.

Next, the operation of the light control data recording / reproducing apparatus 3 configured as described above will be described.
First, the flow of the dimming data recording process will be described.
FIG. 6 is a flowchart showing an example of the flow of recording process of light control data.

  First, it is determined by the control unit 24 whether or not there is a dimming data recording instruction (step S1). If it is determined that there is no dimming data recording instruction, the determination is NO, the process returns to step S1, and the same processing is repeated. On the other hand, if it is determined that there is a dimming data recording instruction, the result is YES, and PWM signals are received by the PWM receivers 22a to 22e (step S2).

  Next, the dimming level of the received PWM signal is measured by the PWM dimming level measuring unit 23 (step S3). Finally, the control unit 24 associates a time stamp with the measured dimming level and stores it in the dimming level storage unit 26 (step S4), and ends the process.

Next, the flow of the dimming data reproduction process will be described.
FIG. 7 is a flowchart illustrating an example of a flow of reproduction processing of dimming data.

  First, the control unit 24 determines whether or not there is an instruction to reproduce the light control data (step S11). If it is determined that there is no instruction to reproduce the light control data, the determination is NO, the process returns to step S11, and the same processing is repeated. On the other hand, if it is determined that there is an instruction to reproduce the light control data, the determination is YES, and the control unit 24 determines whether or not the scene is to be reproduced alone (step S12). If it is determined that the scene is a single reproduction, the control unit 24 reproduces the selected dimming data (step S13) and ends the process.

  On the other hand, if it is determined in step S12 that the scene is not single playback, the control unit 24 determines that time code playback is to be performed. When it is determined that the time code is reproduced, the control unit 24 determines whether or not the time code of the clock unit 25 or the external time code matches the time stamp (step S14). If it is determined that the time stamp does not match, the determination is NO, the process returns to step S14, and the same processing is repeated. On the other hand, if it is determined that the time stamp matches, the control unit 24 reproduces the matched dimming data (step S15) and ends the process.

  As described above, the dimming data recording / reproducing apparatus 3 of the present embodiment outputs the signal level of the final stage signal supplied to the illumination loads 17a to 17e, here, the PWM dimmers 15a to 15e. The dimming level was measured from ON or OFF of the signal level of the PWM signal and recorded as dimming data. And the light control data recording / reproducing apparatus 3 of this Embodiment was made to output the light control signal according to the recorded light control level to illumination load 17a-17e, when reproducing the recorded light control data. As a result, the dimming data recording / reproducing apparatus 3 of the present embodiment can generate a dimming signal regardless of the transmission method between the dimming controller 11 and the dimming panel 12.

  Therefore, according to the dimming data recording / reproducing apparatus 3 of the present embodiment, the dimming data can be recorded and reproduced regardless of the transmission method.

  It should be noted that the steps in the flowcharts in this specification may be executed in a different order for each execution by changing the execution order and performing a plurality of steps at the same time, as long as the steps are not contrary to the nature.

  The present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the scope of the present invention.
