  The serial communication unit 14 performs serial communication based on the Ethernet (registered trademark) protocol between the host controller 40 and other control units 10 via the transmission line L4. In the storage unit 15, addresses individually assigned to the monitoring terminals 31 to 33 are set in association with addresses of the luminaire 1 whose lighting state is controlled by monitoring inputs from the monitoring terminals 31 to 33. .

  FIG. 4 is a block diagram of the transmission adapter 20. The transmission adapter 20 includes a signal processing unit 21, a DALI communication unit 22, a power line carrier communication unit 23, and a storage unit 24 as main components.

  A plurality of transmission lines L2 are connected to the DALI communication unit 22, and signals are transmitted / received to / from the luminaire 1 connected via the transmission line L2 for each system by the DALI method.

  The power line carrier communication unit 23 transmits and receives signals to and from the control unit 10 connected via the transmission line L1 by the power line carrier communication method, and the luminaire 1 connected to the transmission line L2 of each system. Are transmitted and received in a form including one transmission data.

  In the storage unit 24, the address of the control unit 10 and the address of the own device are stored, and the address of the luminaire 1 connected to the transmission line L2 of each system is stored for each system.

  Each time a predetermined reception time elapses, the signal processing unit 21 creates one transmission data including the data received from the luminaire 1 of each system by the DALI communication unit 22 within the reception time. Data is transmitted from the power line carrier communication unit 23 to the control unit 10. In the signal processing unit 21, when the power line carrier communication unit 23 receives data from the control unit 10, the data addressed to the plurality of lighting fixtures 1 included in this data is transmitted from the DALI communication unit 22 to the corresponding illumination. It is made to transmit to the instrument 1, respectively.

  Next, the operation of this illumination control system will be described. Monitoring terminals 31 to 33 are connected to the control unit 10 via a transmission line L3. Each of the monitoring terminals 31 to 33 monitors whether or not there is a trigger input, and when there is a trigger input, transmits monitoring data corresponding to the trigger input to the control unit 10.

  Here, the monitoring terminal 31 monitors the presence / absence of an operation input by the switch S1 as a trigger input. When the switch S1 is operated, monitoring data corresponding to the operation content (on operation or off operation) of the switch S1 is obtained. To the control unit 10. In addition, the monitoring terminal 32 monitors the brightness between the ambient brightness detected by the brightness sensor and a predetermined reference value as a trigger, and when the ambient brightness becomes darker (or brighter) than the reference value, the reference terminal Monitoring data corresponding to light and dark with the value is transmitted to the control unit 10.

  In addition, the monitoring terminal 33 includes a human sensor including a pyroelectric infrared sensor that detects the presence or absence of a person by detecting heat rays emitted from the human body in the detection area, and triggers a detection result of the human sensor. Monitor as input. When the detection result of the human sensor changes, the monitoring terminal 33 transmits monitoring data corresponding to the presence or absence of a person to the control unit 10.

  In the control unit 10, when the multiplex transmission communication unit 13 receives the monitoring data transmitted from any of the monitoring terminals 31 to 33, the signal processing unit 11 creates control data based on the monitoring data. For example, when monitoring data indicating a switch-on operation is input from the monitoring terminal 31, the signal processing unit 11 creates control data for lighting the corresponding lighting fixture 1.

  Then, the signal processing unit 11 causes the generated control data to be transmitted from the power line carrier communication unit 12 to the luminaire 1 in which the correspondence relationship is set in advance with the monitoring terminal that is the transmission source of the monitoring data. When a plurality of lighting fixtures 1 are associated with the monitoring terminal that is the monitoring data transmission source, the signal processing unit 11 includes control data addressed to the plurality of lighting fixtures 1. One transmission data is created, and this transmission data is transmitted from the power line carrier communication unit 12.

  Here, a transmission adapter 20 that relays signals between the control unit 10 and the luminaire 1 is connected, and the power line carrier communication unit 23 of the transmission adapter 20 is transmitted from the control unit 10. Receive control data. The signal processing unit 21 determines whether or not the transmission data received by the power line carrier communication unit 23 includes the address of the luminaire 1 connected to the downstream side of the own device.

  When the transmission data includes the address of the luminaire 1 connected downstream, the signal processing unit 21 extracts control data addressed to the subordinate luminaire 1 from the transmission data, and from the DALI communication unit 22 Transmission is made to the corresponding lighting apparatus 1.

  In each luminaire 1, when the DALI communication unit 5 receives control data addressed to itself, the signal processing unit 2 controls the output of the lighting circuit unit 4 based on the control data, and determines the lighting state of the lamp 3. Change. Here, in the luminaire 1, the lamp 3 made of a fluorescent lamp is fully turned on, dimmed, or turned off according to control data from the control unit 10.

  In addition, when the lighting fixture 1 is equipped with the light emitting diode as a light source, according to the control data transmitted from the control unit 10, you may change the light output of a light emitting diode, or several types from which light emission color differs as a light source. When a light emitting diode is provided, the color temperature may be changed by changing the light output of each color.

  Here, another control operation by the illumination control system of the present embodiment will be described below. First, a description will be given of a control operation for finely setting a dimming range according to a place where a person is present in the above-described illumination control system.

  FIG. 5 shows the arrangement of the luminaire 1. In the office building room 60, six luminaires in the horizontal direction of the room 60 and 18 luminaires in the vertical direction are arranged at regular intervals in the vertical and horizontal directions. ing. And the 1st group G1-G9 is comprised with the two lighting fixtures 1 located in a line with the vertical direction, and the monitoring which detects the presence or absence of the person in a detection area by making the illumination area of each 1st group G1-G9 into a detection area One terminal 33 is provided for each first group.

  In addition, one second group H1 to H9 is configured by three first groups G1 to G9 each in length and width, and the storage unit 15 of the control unit 10 includes the first groups G1 to G9 and the second groups H1 to H1. The address of the lighting fixture 1 belonging to H9 is registered. In FIG. 5, the monitoring terminal 33 is not shown.

  Here, when the monitoring terminal 33 belonging to the first group G5 in the second group H1 and the monitoring terminal 33 belonging to the first group G8 in the second group H6 detect a person, the monitoring terminal 33 moves to the control unit 10. A human body detection signal is transmitted. Since the control operation in the second group H6 is the same as the control operation in the second group H1, the control operation in the second group H1 will be described, and the control operation in the second group H6 will be described. Omitted.

  In the control unit 10, when the human body detection signal is input from the monitoring terminal 33 belonging to the first group G5, the control unit 10 transmits control data for fully lighting (100% lighting) the lighting fixtures 1 belonging to the same first group G5, All lighting fixtures 1 belonging to one group G5 are turned on.

  Further, the control unit 10 turns on the low illuminance (dimming lighting) to the lighting fixtures 1 belonging to the other first groups G1 to G4 and G6 to G9 in the same second group H1 as the monitoring terminal 33 that has output the human body detection signal. ) Control data to be transmitted, and turn on these lighting fixtures 1 in a low illuminance state.

  In addition, the control unit 10 transmits control data to be turned off to the lighting devices 1 of the second group H2 to H5 to which the monitoring terminal 33 that has output the human body detection signal does not belong, and turns off these lighting devices 1. ing.

  Thus, in the place where the person exists (the first group to which the monitoring terminal 33 that has detected the person belongs), the luminaire 1 is fully lit. On the other hand, the luminaire 1 is turned on at low illuminance in the vicinity (another first group belonging to the same second group), and the luminaire 1 is turned off in the vicinity (another second group). Therefore, lighting around the place where people are present with low illuminance suppresses the deterioration of the visual environment and reduces the feeling of loneliness felt by people remaining in the room by darkening the surroundings. Satisfaction can be increased.

  Conventionally, since all the lighting fixtures 1 in the vicinity are lit in a low illuminance state so that the person who remains in the room 60 does not feel lonely, wasteful power consumption is large. On the other hand, in this system, since the lighting fixtures 1 belonging to the second group in which no person is detected are turned off, power saving can be achieved.

  Further, when there is no person in the room 60, the control unit 10 turns off the lighting fixtures belonging to all the second groups, so that the lighting fixture 1 that is turned on in the low illumination state is not forgotten to be turned off. Can do. Further, when all the lighting fixtures 1 are turned off when a predetermined turn-off time comes, the lights are kept on in a low illuminance state until the turn-off time comes. However, in this system, when there are no people in the room 60, all the lighting fixtures are turned on. Since 1 is turned off, the lighting time of the lighting fixture 1 can be shortened, and power saving can be achieved.

  Next, in the above-described illumination control system, a control operation using both brightness dimming using a brightness sensor and timer dimming will be described.

  In this lighting control system, as shown in FIG. 6, a plurality of lighting fixtures 1 are arranged in a rectangular room 60. A window 61 is provided on one surface of the room 60, and a plurality of lighting fixtures 1 having the communication function described above are arranged in a section 60a near the window 61 in the room 60, and a monitoring terminal having a brightness sensor. 32 is installed.

  Further, a plurality of lighting fixtures 1a in which a timer dimming function is added to the above-described lighting fixtures are arranged in a section 60b other than the window side in the room 60. Here, the timer dimming function means that the light output of the lamp 3 is substantially reduced regardless of the lapse of the cumulative lighting time by increasing the lighting output supplied to the lamp 3 as the cumulative lighting time of the lamp becomes longer. This is a function for adjusting the output of the lighting circuit unit 4 so as to be constant.

  In this system, a plurality of lighting fixtures 1 arranged in the partition 60a at the window are set as one group G1, and a plurality of lighting fixtures 1a arranged in the division 60b are set as a group G2, and the lighting fixtures 1 are controlled in units of groups. .

  That is, in the control unit 10, when a brightness detection value is input from the monitoring terminal 32, control data for adjusting the light output so that the detection value becomes a predetermined brightness is sent to the luminaire 1 belonging to the group G1. Send.

  Further, the control unit 10 uses the brightness detection value as the target illuminance based on the brightness detection value input from the monitoring terminal 32 so that the brightness equivalent to that of the window can be obtained even in the section 60b. It transmits to the lighting fixture 1a which belongs to group G2. The luminaire 1a belonging to the group G2 has a timer dimming function. When the target illuminance is input from the control unit 10 as control data, the lighting fixture 1a is connected to the lamp 3 based on the accumulated lighting time and the target illuminance up to now. Controls the lighting output.

  In this lighting control system, the monitoring terminal 32 equipped with a brightness sensor is disposed only in the section 60a by the window, and the brightness detection value of the luminaire 1 of the group G1 disposed in the section 60a has a predetermined brightness. The lighting output is controlled. Therefore, when the outside light is bright such as in the daytime, the lighting output of the luminaire 1 belonging to the group G1 is suppressed, so that wasteful power consumption can be suppressed and the power consumption can be reduced.

  Further, since the section 60b far from the window 61 is expected to be less affected by external light than the section 60a, the monitoring terminal 32 equipped with a brightness sensor is not installed in the section 60b. And in the control unit 10, the control data which makes the brightness detection value from the monitoring terminal 32 installed in the division 60a target illuminance is transmitted to the lighting fixture 1a which belongs to the group G2, and the lighting fixture 1a of the group G2 Controls the lighting output according to the input target illuminance.

  By performing such control, a brightness sensor is not required in the section 60b where the influence of external light is small, and the cost of the lighting control system is reduced as compared with the case where the brightness sensor is installed in the entire room 60. However, it is possible to save power.

  In addition, when the brightness sensor is installed in the whole room 60 and the light output of each lighting fixture 1 is controlled so that the detection result of the brightness sensor becomes the target illuminance, the reflectance of the lower surface of the brightness sensor is The light output of the luminaire 1 may vary due to the difference. In this case, light and darkness occurs in the plurality of lighting fixtures 1 installed on the ceiling surface, and the design of the ceiling surface is degraded.

  On the other hand, since the same target illuminance is input to the lighting fixtures 1 belonging to the group G2 in the above-described lighting control system, the light output of the lighting fixtures 1 belonging to the group G2 can be prevented from varying, and the design of the ceiling surface can be suppressed. Will improve. Moreover, since the lighting fixture 1a installed in the division 60b controls the lighting output by using the brightness detection value input from the monitoring terminal 32 as the target illuminance, the control stability is high, and the control by the disturbance is performed. It is difficult for malfunctions to occur.

  Next, a description will be given of a control operation in the case where the lighting apparatus is turned on after a predetermined time from the detection when the human sensor detects a person with the above-described lighting control system.

  In this lighting control system, a plurality of lighting fixtures 1 installed in the vicinity of a monitoring terminal 33 including a human sensor are set as one group G3, and the control unit 10 is based on a detection result input from the monitoring terminal 33. The lighting state of the lighting fixtures 1 belonging to the group G3 is controlled.

  The control unit 10 is set with a control time zone for performing delayed lighting control for turning on the luminaire 1 after a certain period of time after the human sensor detects a person for a certain period of time. Outside the belt, when the human sensor detects a person, the lighting device 1 is turned on immediately.

  Here, when the current time is outside the above control time zone, when the human body detection signal is input from the monitoring terminal 33 as monitoring data, the control unit 10 transmits control data for lighting the luminaires 1 belonging to the group G3. Send. This control data is transmitted to the lighting fixtures 1 belonging to the group G3 via the transmission adapter 20, and these lighting fixtures 1 turn on the lamps 3.

  The control unit 10 transmits control data for turning off the luminaires 1 belonging to the group G3 when a predetermined lighting holding time has elapsed after the human body detection signal is no longer input from the monitoring terminal 33. This control data is transmitted to the luminaires 1 belonging to the group G3 via the transmission adapter 20, and these luminaires 1 turn off the lamps 3.

  On the other hand, if the current time is the above control time zone, the control unit 10 immediately sends control data for turning on the corresponding lighting fixture 1 even if a human body detection signal is input as monitoring data from the monitoring terminal 33. Do not output. When the human body detection signal is continuously input from the monitoring terminal 33 for a certain time, the control unit 10 transmits control data for lighting the lighting fixtures 1 belonging to the group G3, and the lighting fixture 1 that has received the control data. Turns on the lamp 3.

  Then, the control unit 10 transmits control data for turning off the luminaires 1 belonging to the group G3 when a predetermined lighting holding time has elapsed after the human body detection signal is not input from the monitoring terminal 33, and receives the control data. The lighting fixture 1 turns off the lamp 3.

  In places where there is daylight even at night, by setting the above control time zone, the luminaire 1 is not lit when temporarily passing or stopped (for example, seated), and the lighting holding time thereafter. Since the lighting fixture 1 does not continue to be lit until it continues, power saving can be realized. In addition, when shortening lighting holding time in order to reduce power consumption, it is known that the lighting fixture 1 repeats lighting / extinguishing frequently, and the lifetime of the lamp 3 etc. will become short, and lighting holding time is It is necessary to set a certain length.

  In addition, in a place where there is no light at night, if the above-described delayed lighting control is performed, it is inconvenient because the lighting apparatus 1 is not turned on until a certain time has elapsed since the detection of the human body. Therefore, in such a place, the time zone in which there is no light is not included in the above control time zone, so that when a person is detected, the lighting fixture 1 can be turned on immediately, and convenience is improved.

  Next, an operation when the abnormal state of each lighting fixture 1 is monitored by this lighting control system will be described.

  Each luminaire 1 includes an abnormality detection unit 6 that detects an abnormality (out of sphere) of the lighting circuit unit 4 and the lamp 3. In the signal processing unit 2 of the luminaire 1, when the abnormality detection unit 6 detects an abnormality, a signal indicating the abnormality content is transmitted from the DALI communication unit 5 to the control unit 10. Data transmitted from the lighting fixture 1 is transmitted to the control unit 10 via the transmission adapter 20, and further transmitted from the control unit 10 to the host controller 40.

  When the data for notifying abnormality is transmitted from the lighting apparatus 1, the control unit 10 or the host controller 40 creates a Web page for notifying the abnormality content and transmits it to the personal computer 50. Since the personal computer 50 has a browser function and can display a web page transmitted from the control unit 10 or the host controller 40 on the monitor, the administrator confirms the web page, so that the lighting device 1 Abnormal content can be grasped.

  For example, when inspecting the luminaire 1 installed in a common area in an apartment house or the like, conventionally, with the luminaire 1 turned on, an operator patrols the apartment house and visually inspects it. However, this method requires a lot of labor and cannot be frequently inspected. Therefore, the resident of each dwelling unit discovers a failure of the luminaire 1 and contacts the administrator, so that the luminaire 1 is often exchanged, resulting in a decrease in management service.

  Therefore, the manager of the apartment house uses the accumulated lighting time and the number of blinks as a guide, and when it is used for a certain period of time, it replaces all the lighting fixtures 1 regardless of whether there are any abnormalities. It was uneconomical because it was discarded.

  On the other hand, in this system, each luminaire 1 is provided with an abnormality detection unit 6, and when the luminaire 1 detects an abnormality, the information is transmitted to the control unit 10 and the host controller 40. Since the abnormality of the lighting fixture 1 can be found without performing a patrol check, the abnormality of the lighting fixture 1 can be quickly dealt with, labor saving of maintenance inspection can be achieved, and the facility management service can be improved.

  Next, the operation when the power consumption of each lighting fixture 1 is monitored by this lighting control system will be described.

  In each luminaire 1, the signal processing unit 2 is provided with a power consumption detection function for detecting the instantaneous power consumption of the own device from the input current and the input voltage of the lighting circuit unit 4, and the power consumption at a predetermined measurement cycle. Are sent to the control unit 10.

  The transmission adapter 20 calculates the power consumption by integrating the instantaneous power consumption of each lighting fixture 1 received at a constant measurement cycle with the above measurement cycle, and transmits transmission data including the power consumption of each lighting fixture 1. The data is created and transmitted to the control unit 10, and this data is further transmitted from the control unit 10 to the host controller 40.

  When the control unit 10 or the host controller 40 receives the power consumption of each lighting fixture 1, the power consumption is accumulated for each lighting fixture 1 to obtain the power consumption of each lighting fixture 1. In addition, the control unit 10 and the host controller 40 create a Web page that displays the power consumption amount of each lighting fixture 1 and the power consumption amount of each department and transmit it to the personal computer 50, and display it on the monitor of the personal computer 50. The amount of power consumption can be ascertained from the Web page that has been set.

  Therefore, by comparing the power consumption of the individual lighting fixtures 1 and the power consumption of the lighting fixtures 1 included in a predetermined management unit over an arbitrary period, the power consumption status and the power saving effect can be grasped. Can be used to reduce power consumption. In addition, by comparing trends in power consumption in a plurality of management units, it is possible to consider a method for reducing power consumption from the difference in power consumption.

  In addition, since conventional power measurement is performed by the power supply unit that supplies power to the luminaire, power measurement can be performed only in a unit that is aggregated to some extent. For example, the power consumption for each group or department in the office is obtained. Therefore, the power consumption amount of each unit can be obtained only by apportioning the entire power consumption amount. In addition, when the partition in the office is changed, the measurement unit cannot be easily changed.

  On the other hand, in this system, each lighting fixture 1 has a function of detecting the power consumption of its own device, so that it is possible to measure the power consumption in a free way and to change the measurement unit. Can be easily handled.

  As described above, the lighting control system of the present invention includes the lighting fixture 1 having a communication function and the control unit 10 having a function of transmitting / receiving data to / from the lighting fixture 1. The control unit 10 transmits control data for controlling the lighting state of the lighting fixture 1 to the lighting fixture 1, and the lighting fixture 1 controls the lighting state according to the received control data. Moreover, the lighting fixture 1 has a failure detection function for detecting a failure of the own device, and transmits a failure state to the control unit 10 when the failure of the own device is detected.

  Thus, since the lighting fixture itself has a communication function, data can be transmitted to and received from the control unit 10. Therefore, it is not necessary to provide a device having a communication function (conventional relay control terminal) separately from the lighting fixture in order to control the lighting state of the lighting fixture or to monitor the operation status of the lighting fixture. Cost can be reduced.

  In addition, when a relay control terminal is provided separately from the lighting fixture as in the past, it is necessary to wire between the remote control relay arranged in the distribution board and the lighting fixture. However, since such a relay control terminal is not necessary, it is possible to easily cope with a case where the grouping of lighting fixtures is changed. Moreover, the failure state of each lighting fixture 1 can be easily grasped on the control unit 10 side.

  In this lighting control system, a transmission adapter 20 that relays signals is connected between the plurality of lighting fixtures 1 and the control unit 10. When the transmission adapter 20 receives data transmitted to the control unit 10 from a plurality of lighting fixtures 1 connected to the downstream side, the transmission adapter 20 creates transmission data including these data and transmits the transmission data to the control unit 10. . In addition, when the transmission adapter 20 receives transmission data from the control unit 10, the transmission adapter 20 transmits data addressed to the plurality of lighting fixtures 1 included in the transmission data to the corresponding lighting fixture 1.

  Thereby, in the transmission adapter 20, the data sent from the plurality of lighting fixtures 1 connected to the downstream side are collected into one transmission data and transmitted to the control unit 10, and the plurality of units connected to the downstream side are transmitted. The data transmitted from the control unit 10 to the lighting fixture 1 is collectively received. Therefore, communication traffic can be reduced as compared with the case where data is transmitted from the individual lighting fixtures 1 to the control unit 10 or the case where data is transmitted from the control unit 10 to the individual lighting fixtures 1.

  Moreover, the above-described lighting control system includes monitoring terminals 31 to 33 that communicate with the control unit 10 in a communication mode different from the communication performed between the lighting fixture 1 and the control unit 10. The monitoring terminals 31 to 33 monitor the presence or absence of a trigger input. When there is a trigger input, the monitoring terminals 31 to 33 transmit monitoring data corresponding to the trigger input to the control unit 10.

  Thereby, in the control unit 10, the lighting state of the lighting fixture 1 can be controlled based on the monitoring data input from the monitoring terminals 31-33. Moreover, since the communication performed between the control unit 10 and the monitoring terminals 31 to 33 is different from the communication performed between the control unit 10 and the lighting fixture 1, it is possible to suppress an increase in communication traffic. it can.

  In addition, it is also preferable that the monitoring terminals 31 to 33 are connected to a transmission line through which the lighting fixture 1 and the control unit 10 communicate, and it is not necessary to separately wire an electric wire for connecting the monitoring terminals 31 to 33. Workability is improved. In this case, a signal exchanged between the control unit 10 and the monitoring terminals 31 to 33 and a signal exchanged between the control unit 10 and the lighting fixture 1 are multiplexed and transmitted. .

  Moreover, in the illumination control system of this embodiment, a plurality of control units 10 are provided, and a plurality of control units 10 have a function of communicating with each other. By providing a plurality of control units 10 in this way, the number of controllable lighting fixtures 1 can be increased.

  In the present system, an upper controller 40 that controls the entire system is further provided above the control unit 10, and the entire system can be controlled by the upper controller 40.

  Further, in this system, each lighting fixture 1 has a power consumption detection function for detecting the power consumption of its own device, and transmits the detection result of the power consumption to the control unit 10. Thereby, the power consumption amount of each lighting fixture 1 can be grasped on the control unit 10 side, and the power consumption amount is grasped in a desired unit by adding the power consumption amount of each lighting fixture 1. be able to.

  In this lighting control system, the lighting fixture 1 itself is provided with a human sensor for detecting the presence or absence of a person in a detection area provided in the lighting area, and the detection result of the human sensor is transmitted to the control unit 10. Is also preferable. At this time, in the control unit 10, based on the detection result of the human sensor transmitted from the lighting fixture 1, a plurality of lighting fixtures 1 including the lighting fixture 1 of the transmission source are turned on.

  Thus, in the control unit 10, since the lighting state of the plurality of lighting fixtures 1 is controlled according to the presence / absence of a person in the detection area, for example, if the lighting state is reduced in the absence of a person, Power saving can be achieved.

  In this lighting control system, it is also preferable that the lighting fixture 1 itself is provided with a brightness sensor that detects ambient brightness, and the detection result of the brightness sensor is transmitted to the control unit 10. At this time, the control unit 10 controls the lighting state of a plurality of lighting fixtures 1 including the transmission source lighting fixture 1 based on the detection result of the brightness sensor transmitted from the lighting fixture 1.

  Thereby, the control unit 10 can control the lighting state of the plurality of lighting fixtures 1 according to the detection result of the brightness sensor. For example, when the surroundings are bright due to daylight or the like, the lighting state can be lowered. Thus, power saving can be achieved.

  Also, in this lighting control system, a host controller 40 that is provided above the control unit 10 and controls the entire system is monitored, and the presence or absence of a trigger input is monitored. When there is a trigger input, monitoring data corresponding to the trigger input is generated. However, it is also preferable to provide each lighting device 1 with a sensor (for example, a human sensor or a brightness sensor) that detects a change in the surrounding environment. In each luminaire 1, when the sensor of the own device detects a change in the surrounding environment (for example, when the brightness detection result becomes brighter than a predetermined reference value or the presence or absence of a person changes), the control unit 10 receives the sensor. A detection result is transmitted, and this detection result is further transmitted from the control unit 10 to the host controller 40. One of the control unit 10 and the host controller 40 controls one or more lighting fixtures 1 as a group to control the lighting state in units of groups, and the monitoring data and sensors of the monitoring terminals 31 to 33 are controlled. When any of the detection results is input, the lighting fixtures 1 belonging to the group for which the correspondence relationship is set in advance are controlled to a predetermined lighting state.

  Thereby, one or a plurality of lighting fixtures 1 are grouped, and the lighting fixtures 1 in the group are controlled to a predetermined lighting state in accordance with monitoring data from the monitoring terminals 31 to 33 or sensor detection results. Can do.

  In addition, as a unit (group) for performing group control, a first group G1 ... composed of one to a plurality of lighting fixtures 1 and a second group H1 ... composed of a plurality of first groups G1 ... are set. Any one of the control unit 10 and the host controller 40 turns on the luminaire belonging to the first group in which the correspondence relationship is set in advance based on either the monitoring data of the monitoring terminals 31 to 33 or the detection result of the sensor. When it is made to do, the lighting fixture which belongs to another 1st group within the same 2nd group is controlled to the predetermined lighting state, and the lighting state of the lighting fixture 1 can be controlled by a fine division. In addition, when using a relay control terminal that switches on / off of lighting fixtures as in the past, wiring work may be required due to a change in unit (group) for group control or a layout change. In this system, since each lighting fixture 1 has a communication function, the unit for performing group control can be changed for each lamp, and wiring work is not necessary, so that the workability is improved.

  The control unit 10 of the present invention has a function of transmitting and receiving data to and from the lighting fixture 1 having a communication function and a failure detection function for detecting a failure of the own device. And the control unit 10 transmits the control data which controls the lighting state of the lighting fixture 1 to the lighting fixture 1, and receives the failure state of the lighting fixture 1 transmitted from the lighting fixture 1.
