Description

  The present invention relates to a lighting control system.

  2. Description of the Related Art Conventionally, there has been proposed a system that uses an illuminance sensor to control illuminance of illumination to be constant, thereby ensuring sufficient illuminance on a work surface and realizing energy saving. For example, Japanese Utility Model Publication No. 54-152 describes an example of a system in which an illuminance sensor is provided in a lighting fixture and the illuminance of the lighting fixture is controlled so that the level (illuminance detection value) received by the sensor is always constant. . However, when an illuminance sensor is provided for each lighting fixture, it is necessary to individually set an illuminance reference value for determining the brightness of the area to be controlled for each of the lighting fixtures. Since the luminaire is mounted on the ceiling, there is a problem that setting the illuminance reference value is difficult.

  Therefore, an illuminance control signal obtained by comparing the light receiving levels of a plurality of illuminance sensors provided for a plurality of areas with a set illuminance reference value is transmitted to a lighting fixture installed for each area. If a system including a controller is used, the illuminance setting need only be performed for the controller, and the illuminance setting operation can be facilitated. However, if the number of areas to be controlled is large, signal lines for transmitting the detection signals of multiple illuminance sensors must be wired to the controller, which complicates the wiring and complicates the work when constructing the system. There was a problem of becoming.

  Therefore, in order to avoid the above problem, a system as shown in FIG. 9 has been developed. In this system, one illuminance sensor 6 is connected to the central controller 1 directly or via a signal line, and the central controller 1 performs time division through the transmission line 2 so that the light receiving level of the illumination sensor 6 becomes constant. By controlling the dimming terminals 3a, 3b,... 3n provided in each area by multiplex transmission, the illuminance of the lamp 5 is controlled to be constant. For this reason, a signal line for transmitting the detection signal of one illuminance sensor 6 may be wired to the central control device 1, and the problem of complicated wiring of the signal line for transmitting the detection signal of the illuminance sensor 6 is avoided. be able to.

  However, in such a system, when the illuminance of the lamp 5 is controlled by the dimmer terminals 3a, 3b,... 3n via the dimmers 4a, 4b,. Then, the number of feedback systems to be fed back to the central control device 1 is formed as many as the number of dimming terminals. For this reason, as the number of dimming terminals increases, the transmission interval of the illuminance control signal transmitted from the central control device 1 to one dimming terminal via the transmission line 2 increases, and the processing of the central control device increases. There is a problem that the burden increases and the responsiveness of the system deteriorates.

That is, for example, even if the illuminance of the lamp 5 of the dimming device 4a connected to the dimming terminal 3a decreases and the illumination sensor 6 detects that the illuminance of the lamp 5 has decreased, the illuminance to correct this Since the control signal is not easily transmitted from the central control device 1, it takes time to return the illuminance of the lamp to the original brightness.
JP-A-6-139805 (page 2, FIG. 1)

  By providing a controller that collectively controls the illuminance of a plurality of lighting fixtures installed for each area as described above, and by setting an illuminance reference value to this controller, it is easy to set the illuminance reference value. However, there is a problem in that the wiring for transmitting the detection signals of the plurality of illuminance sensors to the controller is complicated, and the work when constructing the system is complicated.

  Therefore, in order to avoid this problem, the central control device 1 switches a plurality of dimming terminals 3a, 3b,... 3n installed in each area based on the light receiving level detected by one illuminance sensor 6. In a system in which the illuminance of the lamp 5 in each area is controlled by division multiplex transmission, there is a problem that the response of the system deteriorates as the number of dimming terminals increases.

  An object of the present invention is to provide a lighting control system that can control illuminance of a plurality of areas with good responsiveness and that can easily set illuminance.

  According to the first aspect of the present invention, a transmission line for transmitting a control signal; a correspondence line between the transmission line and the illuminance and a sensor level of the illuminance sensor is determined, and an illuminance detection value detected by the illuminance sensor is set in advance. At least one dimming terminal for generating a dimming control signal for dimming the lamp to match an illuminance reference value; and a dimming terminal by transmitting the illuminance reference value to the dimming terminal over a transmission line. And a setting means for setting an illuminance reference value in the central control device.

  According to the present invention, the central control device transmits the illuminance reference value set by the setting means as needed to the dimming terminal via the transmission line. The light control terminal internally sets the transmitted illuminance reference value addressed to itself. The dimming terminal first determines the correspondence between the illuminance and the sensor level of the illuminance sensor, and controls the dimming of the PWM so that the illuminance detection value detected by the illuminance sensor matches a preset illuminance reference value. A signal is created and sent to the dimmer through the signal line. The dimmer controls the dimming of the lamp based on the input dimming control signal, and controls the illuminance of the area where the lamp is installed at the target illuminance determined by the illuminance reference value.

  Therefore, in the dimming terminal, the correspondence between the illuminance and the sensor level of the illuminance sensor can be obtained. Even if the number of dimming terminals increases, the illuminance of the area is controlled by the respective feedback systems including the dimming terminals, so that the responsiveness of the illuminance control of each area is not affected. Also, as the number of dimming terminals increases, the central control unit transmits an illuminance reference value to each dimming terminal via a transmission line, and the number of processes for setting these dimming terminals increases. It does not affect the responsiveness of the illuminance control of each area described above.

  Accordingly, if the illuminance of the area is appropriately determined for the response of the feedback system including each dimming terminal, good responsiveness to illuminance control can be maintained regardless of the increase or decrease in the number of dimming terminals. In addition, since the setting of the illuminance reference value for each dimming terminal is automatically performed by the central control device, the work of setting the illuminance reference value becomes extremely easy.

  According to a second aspect of the present invention, in the illumination control system according to the first aspect, the dimming terminal creates a plurality of sub-illuminance reference values from the illuminance reference values set by the setting means, and detects the illuminance detected by the illuminance sensor. Dimming control of a plurality of lamps is performed so that the value matches the sub-illuminance reference value.

  In the present invention, the dimming terminal creates, for example, first and second sub-illumination reference values from the set illumination reference values. Thereafter, the dimming terminal controls the dimming of the first system lamp so that the illuminance detection value detected by the illuminance sensor coincides with the first sub-illumination reference value. The dimming control of the lamps of the second system is performed so that the illuminance detection value detected by (1) matches the second sub illumination reference value.

  This makes it possible to further subdivide one area and individually control the illuminance.

  According to a third aspect of the present invention, in the illumination control system according to the first or second aspect, an actual measured value input for inputting an actual measured value of the illuminance of an area where a lamp which is lit and controlled to be lit is arranged to a central control device. Means; and correction means for correcting the illuminance reference value so that the illuminance of the actually measured value input by the actually measured value input means matches the target illuminance value determined by the illuminance reference value set by the setting means. Features.

  In the present invention, the illuminance of the actually measured value input by the actually measured value input means is, for example, 300 lux, and the target illuminance determined by the illuminance reference value set by the setting means is 500 lux. In such a case, the correction unit increases the illuminance of the actual measurement value input by the actual measurement value input unit to the target illuminance of the illuminance reference value set by the setting unit. To correct the illuminance reference value.

  As a result, a corrected illuminance reference is set in the dimming terminal, and the dimming control of the lamp is performed based on the illuminance reference. Therefore, the illuminance is controlled to a target of 500 lux, which is caused by the arrangement of the lamp and the height of the ceiling. The illuminance deviation is corrected, and illuminance control is performed as specified.

  According to a fourth aspect of the present invention, in the illumination control system according to the first or second aspect, a lighting means for setting a calibration illuminance reference value in the dimming terminal and controlling the dimming of the lamp with the calibration illuminance reference value. Transmitting means for transmitting the detected illuminance value detected by the illuminance sensor to the central control device via a transmission line when the lamp is lit by the lighting means; and the illuminance detected value transmitted by the transmitting means and the illuminance for calibration Correction means for correcting the illuminance reference value set by the setting means based on a difference from a target illuminance value determined by the reference value.

  In the present invention, it is assumed that the target illuminance determined by the illuminance reference value for calibration set in the dimming terminal is 300 lux. When the illuminance detection value detected by the illuminance sensor when the lighting unit illuminates the lamp with the illuminance reference value for calibration is 200 lux, the transmission unit transmits the illuminance detection value of 200 lux to the central control device. I do. The correcting means uses the difference of 100 lux between the illuminance detection value of 200 lux transmitted by the transmitting means and the target illuminance of 300 lux determined by the illuminance reference value for calibration, and the target of the lamp whose dimming control is performed by the dimming terminal. Since the deviation between the illuminance to be performed and the actual illuminance is known, the illuminance reference value set by the setting means is corrected so that this deviation does not occur.

  As a result, the corrected illuminance reference value is set in the dimming terminal, and the dimming control of the lamp is performed based on the illuminance reference, so that the illuminance is controlled without deviation from the target illuminance, and the illuminance control as specified is performed. Is

  According to the first aspect of the present invention, in the dimming terminal, the correspondence between the illuminance and the sensor level of the illuminance sensor is determined, and the illuminance detection value detected by the illuminance sensor matches the preset illuminance reference value. As described above, since the dimming control signal for dimming the lamp is generated, the illuminance of a plurality of areas can be controlled with good responsiveness, and the illuminance can be easily set.

  According to the invention of claim 2, by controlling the illuminance of a plurality of lamps individually with one dimming terminal, the area in which the dimming terminal is installed is subdivided and each illuminance is individually set. Can be controlled.

  According to the third aspect of the present invention, each area can be controlled with the illuminance as specified by correcting the illuminance reference value in accordance with the installation conditions of the lamp, the structure of the room, and the like.

  According to the invention of claim 4, it is possible to easily correct the illuminance reference value and control each area with the illuminance as specified.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a first embodiment of a lighting control system according to the present invention. Reference numeral 1 denotes a central control device for performing control such as setting an illuminance reference value for the dimming terminals 3a and 3b by time division multiplexing transmission through the transmission line 2, and 2 connects the central control device 1 to the dimming terminals 3a and 3b. Transmission lines 4a1, 4a2, 4b1, and 4b2 for transmitting control signals and data by time-division multiplexing are dimmers whose dimming is controlled by dimming terminals 3a and 3b, and 5 are dimmers 4a1 and 4a2. Lamps mounted on 4b1 and 4b2, 6a is an illuminance sensor that outputs the received light level as an illuminance detection value to dimming terminal 3a, and 6b is an illuminance sensor that outputs the received light level as an illuminance detection value to dimming terminal 3b. , 7a connect the dimming terminal 3a and the dimming devices 4a1 and 4a2 to transmit a PWM signal, for example, a 4-wire signal line, and 7b connects the dimming terminal 3b and the dimming devices 4b1 and 4b2. Connect and P Transmitting M signals for example 2-wire signal line, 8 denotes an input unit for illuminance reference value for determining whether to how much the illuminance of the lamps 5 for each area input to the central control unit 1.

  The illuminance sensor 6a, the dimming terminal 3a, the dimming devices 4a1 and 4a2 and the illuminance sensor 6b, the dimming terminal 3b, and the dimming devices 4b1 and 4b2 are provided for each area to be controlled. . The illuminance sensors 6a and 6b are usually installed on the ceiling to measure the illuminance on the desk surface. The sensor level of the illuminance sensor 6 has a detection range of DC 0 V to 5 V, and has a correspondence relationship of, for example, 700 IX (lux) = 3.1 V (volt). The dimmers 4b1 and 4b2 are two-wire systems, and the dimmer signal is a DCI 2V, 100 Hz PWM signal supplied from the dimmer terminals 3a and 3b. Although not shown, an AC power supply, for example, AC 100 V is supplied to the dimmer.

  FIG. 2 is a block diagram showing a detailed configuration example of the dimming terminal 3a (or 3b) shown in FIG. 31 is a transmission / reception unit for transmitting / receiving signals to / from the transmission line 2, 32 is a control unit such as a microcomputer for performing signal transmission / reception control and dimming control, 33 is an address storage unit for storing its own address information, and 34 is illuminance An illuminance sensor receiving unit 35 that receives a signal from the sensor 6a and inputs the signal to the control unit 32. A dimming signal output 35 outputs a PWM dimming signal for dimming control of the dimming device 4a1 and the like on the signal line 7a. Reference numeral 36 denotes a memory for holding an illuminance reference value.

  FIG. 3 is a circuit diagram showing a detailed configuration example of the illuminance sensor 6a described above. The current of the photodiode 61 changes according to the level of the received light. For this reason, this current change is converted into a voltage, amplified by the amplifier 62, becomes an illuminance detection signal, and transmitted to the dimming terminal 3a. The configuration of the illuminance sensor 6b is the same.

  Next, the operation of the present embodiment will be described. First, an illuminance reference value that determines the illuminance of an area illuminated by the lamp 5 whose dimming is controlled by the dimming terminals 3a and 3b is input to the central control device 1 and set. The setting of the illuminance reference value may be performed cyclically, or may be performed as needed. Thus, when the illuminance reference value is newly set or the setting is changed, the central controller 1 converts the illuminance reference value into a control signal format as shown in FIG. Send to 3a, 3b.

  Here, FIG. 4 is a diagram showing a format example of the above-described control signal. It consists of a 4-bit start section 41, an 8-bit address section 42, an 8-bit data section 43 and a response data section 44 on the dimming terminal side in order from the top. The address of the dimming terminal to which data is transmitted is stored in the address section 42, and the illuminance reference value described above is stored in the data section 43.

  Upon receiving the control signal on the transmission line 2, the transmission / reception unit 31 of the dimming terminal 3 a passes the address of the received control signal to the control unit 32. The control unit 32 fetches the control signal received by the transmission / reception unit 31 only when the passed address matches its own address in the address storage unit 33. The control unit 32 extracts an illuminance reference value from the fetched control signal and sets the illuminance reference value in the memory 36.

  On the other hand, the illuminance sensor 6a transmits the light reception level to the illuminance sensor receiver 34 as an illuminance detection signal. The illuminance sensor receiver 34 inputs the received illuminance detection signal to the controller 32. The control unit 32 compares the input illuminance detection signal with the illuminance reference value set in the memory 36, and determines a dimming control signal for dimming the lamp 5 attached to the dimming devices 4a1 and 4a2 from the difference. It is created and output to the dimming signal output unit 35. The dimming signal output unit 35 sends out the input dimming control signal as a PWM signal onto the signal line 7a.

  The dimmers 4a1 and 4a2 adjust the power output to the lamp 5 based on the input PWM signal to perform dimming. Since the dimming control of the lamp 5 by the control unit 32 is performed so that the difference becomes zero, the illuminance detected by the illuminance sensor 6a is stored in the memory 35 by controlling the dimming of the lamp 5 after all. The target illuminance is determined by the set illuminance reference value, and the brightness of the area illuminated by the lamp 5 attached to the dimmer 4a1 or 4a2 is controlled to the illuminance set by the illuminance reference value. . FIG. 5 is a diagram showing a case where the illuminance sensor 6a is actually attached to a ceiling or the like of a room. As shown in FIG. 5A, the photodiode 61 and the amplifier 62 shown in FIG. In particular, the photodiode 61 is disposed in a hemispherical light-receiving portion 52 that transmits light, and light from the room enters through the light-receiving portion 52 and is photoelectrically converted by the photodiode 61. As shown in FIG. 5B, the illuminance sensor 6a is mounted on the ceiling plate 53 such that the light receiving unit 52 faces directly below, and finally, a plate 54 is mounted on the outer peripheral portion of the front surface of the light receiving unit 52.

  By the way, depending on the mounting position of the illuminance sensor 6a and the dimmers 4a1 and 4a2, the height of the ceiling, and the like, the illuminance according to the specification may not be obtained with the illuminance reference value set in the memory 36. In such a case, for example, the dimming terminal 3a controls the dimming of the lamp 5 of the dimmer 4a1 based on the illuminance reference value and turns on the lamp 5, and the illuminance at that time is measured.

  Thereafter, when the measured value is input from the input unit 8 to the central control device 1, the central control device 1 compares the target illuminance value determined by the illuminance reference value set in the dimming terminal 3a with the measured value, and The illuminance reference value is corrected so that the value becomes the target illuminance value. That is, the illuminance reference value is corrected according to the mounting condition of the lamp 5 of the light control device 4a1 and the structure of the building. Thereafter, the corrected illuminance reference value is set in the memory 36 of the light control terminal 3a via the transmission line 2. As a result, the dimming terminal 3a controls the dimming of the lamps 5 of the dimming devices 4a1 and 4a2 based on the corrected illuminance reference value. Control to illuminance.

  FIG. 6 is a flowchart showing the correction processing of the illuminance reference value by the central control device 1 described above. The central controller 1 inputs the actual measurement value from the input unit 8 in step 601, and in step 602, calculates a difference between the actual measurement value and the target illuminance value determined by the illuminance reference value set at this time. Next, the central control device 1 corrects the illuminance reference value based on the difference in step 603, and transmits the corrected illuminance reference value to the corresponding dimming terminal device via the transmission line 2 in step 604. To end.

  According to the present embodiment, the illuminance control of the area is performed by, for example, a feedback loop between the illuminance sensor 6a, the dimming terminal 3a, the dimming devices 4a1, 4a2, and the lamp 5. 1 and the central controller 1 merely sets the illuminance reference value to the dimming terminal 3a as necessary using the transmission line 2, so that even if the number of dimming terminals increases, the illuminance reference value Is hardly delayed, so that the feedback loop of each area is not affected, and the responsiveness of the illuminance control can be maintained satisfactorily. The setting of the illuminance reference value is performed by the input unit 8 for the central control unit 1, and thereafter, the central control unit 1 automatically sets the dimming terminals 3a and 3b via the transmission line 2. In addition, the work of setting the illuminance reference value can be extremely facilitated.

  FIG. 7 is a block diagram showing a second embodiment of the lighting control system of the present invention. In this example, two lines of signal lines 7a1 and 7a2 and two lines of signal lines 7b1 and 7b2 are connected to the dimming terminals 3a and 3b, respectively, and the dimming devices 4a11, 4a21, and 4a12 connected to the signal lines of each system respectively. Dimming control of the lamps 5 attached to the lamps 4a22 and 4b11, 4b21, 4b12, 4b22 is separately performed. The other configuration is the same as that of the first embodiment shown in FIG. 1, and the detailed configuration of the dimming terminal 3a is the same as that of FIG. 2, so that FIG. explain.

  Next, the operation of the present embodiment will be described. The illuminance reference value is set in the memory 36 of the dimming terminal 3a from the central control unit 1 through the transmission line 2. The control unit 32 of the light control terminal 3a creates two types of sub-illuminance reference values for the signal lines 7a1 and 7a2 from the illuminance reference values set in the memory 36. For example, the set sub illuminance reference value of the signal line 7a1 is used as it is, and the illuminance reference value of the signal line 7a2 is set in the memory 36 using 80% of the set illuminance reference value as the sub illuminance reference value.

  Thereafter, the control unit 32 compares the illuminance detection signal of the illuminance sensor 6a input from the illuminance sensor reception unit 34 with the sub illuminance reference value for the signal line 7a1, and creates a dimming control signal for the signal line 7a1. Then, this is transmitted to the signal line 7a1, and the dimming control of the lamp 5 of the dimmer 4a11, 4a21 is performed. Further, the control unit 32 compares the illuminance detection signal of the illuminance sensor 6a input from the illuminance sensor reception unit 34 with the sub illuminance reference value for the signal line 7a2, and creates a dimming control signal for the signal line 7a2. Then, this is transmitted to the signal line 7a2, and the dimming control of the lamp 5 of the dimmer 4a12, 4a22 is performed. This makes it possible to separately control the illuminance of the lamps 5 of the dimmers 4a11 and 4a21 and the illuminance of the lamp 5 of the dimmers 4a12 and 4a22. The same applies to the dimming terminal 3b.

  Also in this example, the illuminance according to the specification may not be obtained with the illuminance reference value set in the memory 36. In such a case, for example, the lamps 5 of the dimmers 4a11 and 4a21 are adjusted based on the illuminance reference value for calibration (set from the beginning) set in the memory 36 of the dimmer terminal 3a. Light is controlled by light. The control unit 32 of the light control terminal 3a transmits the illuminance detection signal of the illuminance sensor 6a input from the illuminance sensor reception unit 34 at this time to the central control device 1 from the transmission / reception unit 31 via the transmission line 2.

  The central control device 1 compares the illuminance value indicated by the received illuminance detection signal with a target illuminance value determined by the illuminance reference value for calibration set in the dimming terminal 3a, and compares the illuminance indicated by the illuminance detection signal for calibration. Find the difference between the value and the target illuminance value. Next, the central control device corrects the illuminance reference value set from the input unit 8 based on the obtained difference so that the illuminance of the lamp 5 of the dimmer 4a11 or 4a21 is turned on at the target illuminance value determined by the illuminance reference value. Do. Thereafter, the corrected illuminance reference value is set in the memory 36 of the light control terminal 3a. As a result, the dimming terminal 3a controls the dimming of the lamps 5 of the dimmers 4a11, 4a21 and 4a12, 4a22 based on the corrected illuminance reference value, and thus controls this area with the illuminance as specified. The correction of the illuminance reference value is the same for the dimming terminal 3b.

  FIG. 8 is a flowchart showing the correction processing of the illuminance reference value by the central control device 1 described above. When the central control device 1 receives the illuminance detection signal from the dimming terminal in step 801, the illuminance indicated by the illuminance detection value received in step 802 and the target illuminance value determined by the illuminance reference value set at this time. Find the difference between. Next, the central controller 1 corrects the illuminance reference value set from the input unit 8 based on the difference in step 803, and in step 804, applies the corrected illuminance reference value through the transmission line 2 to the corresponding dimming terminal. And the process ends.

  According to the present embodiment, the dimming terminal 3a (or 3b) controls the illuminance of the plurality of lamps 5 with individual illuminance without increasing the number of illuminance reference values set in the central control device 1. It can be performed. Further, the illuminance reference set in the dimming terminal 3a (or 3b) can be automatically corrected without actually measuring the illuminance, and the usability of the system can be improved. Other effects are the same as those of the first embodiment shown in FIG.
