Description

  The present invention relates to a lighting control system, and more particularly to a lighting control system that manages a lighting fixture having an initial illumination correction function.

  In recent years, various lighting control systems have been proposed that can achieve energy savings without impairing comfort during use of a lighting fixture.

  For example, in order to centrally manage the power consumption of the lighting fixture, the power consumption is calculated based on the power consumption of the lighting fixture and the state information of the load on the transmission communication (eg, ON / OFF, dimming level, ON time). There is a remote monitoring and control system with means for calculating. In this remote monitoring and control system, when grasping the electric energy of each lighting fixture (circuit system), it is possible to reduce the cost, space, and labor of installing a large number of current transformers (CT).

  In the calculation method of the power consumption of the lighting fixture, for example, as shown in FIG. 11A, the power consumption (100% lighting state) of the lighting fixture is constant with respect to the energization time, and the dimming level and the power consumption Similarly, it is used that the relationship is constant with respect to the energization time. And if the model of a lighting fixture can be specified, the consumption of the lighting fixture used as shown in FIG.11 (b) from the presence or absence of lighting and a lighting control level based on the relationship between the light control level and consumption current for every model. The power (W) is uniquely determined. Therefore, the power consumption (Wh) of the luminaire can be calculated as shown in FIG. 11 (c) by multiplication with the usage time (h) for each dimming level.

  Note that the standard characteristic based on the rated value is actually used for the relationship between the light control level and the power consumption. Accordingly, since variations among lighting fixtures, deterioration, temperature environment, and the like are not taken into consideration, a certain measurement error associated with the calculation can be included as compared with direct measurement using a current transformer.

  As a configuration of a lighting control system that manages a large number of lighting fixtures, for example, there are cases where the transmission master unit of the transmission system is the same as the lighting management device, and the transmission master unit of the transmission system is a separate device from the lighting management device. is there. Note that the calculation method of the power consumption of the lighting fixture is the same whether the transmission parent device is the same as the lighting management device or a separate device.

  In recent years, lighting fixtures with an initial illuminance correction function have been sold to perform more efficient power saving. Considering the nature of the lamp that gradually gets darker as the lamp life approaches, the fixtures are designed so that the required illuminance can be secured even at the end of the lamp life, so it is common for the illuminance to exceed that required at the beginning of lamp replacement . Therefore, in a lighting fixture with an initial illumination correction function, excessive light output when switching to such a new fluorescent lamp is suppressed (dimming) to an appropriate output, that is, by performing initial illumination correction control, The illuminance obtained can be made constant.

  This lighting control system has a counter (clock) inside, and records the elapsed lighting time with this counter, and increases the light output toward full lighting at a predetermined rate according to the count value. Go. This mechanism reduces unnecessary illuminance associated with the fluorescent lamp output characteristics at the initial stage of lamp replacement, and can automatically perform necessary energy saving. Therefore, in order to correctly perform the initial illuminance correction function, it is necessary to reset the counter of the cumulative lighting time (set the counter value to 0) when replacing with a new fluorescent tube (lamp).

  Normally, the counter resetting of the cumulative lighting time includes an automatic reset that is automatically reset at the same time as the lamp is replaced when the lighting fixture detects and judges when the lamp life is reached. In addition, when replacement is performed without lamp life such as lamp breakage or equipment operation, the counter is reset based on the combined procedure of whether or not the lamp is installed and turning on and off the appliance power supply at a predetermined timing. There is a manual reset as determined by the instrument. Confirmation that the resetting of the counter value has been completed enables visual confirmation of the presence or absence of an operation such as the brightness of the lamp immediately after the replacement operation changing from maximum light emission to dimming (dimming) after 10 seconds, for example.

  By the way, it is possible to correct the initial illuminance corresponding to a space (for example, a store) where the dimming level is changed according to the difference in reflectivity on the floor surface, time (time), etc. An apparatus is known (see, for example, Patent Document 1). In addition, an illumination device that controls input of the air conditioner and the illumination device based on the temperature in the vicinity of the illumination device and an operation method thereof are also disclosed (for example, see Patent Document 2).

  However, there are the following two problems in the illumination control system having the conventional illumination fixture with the initial illumination correction function.

  That is, (1) For a lighting fixture with an initial illuminance correction function, there is a problem that it is impossible to calculate a uniform amount of power consumption as in the conventional case due to an increased error. This is because, in the conventional calculation of the electric energy, it is assumed that the power consumption of the lighting fixture is constant with respect to the usage time as shown in FIG. However, in lighting fixtures with an initial illuminance correction function, the lamps are lit brightly in the initial stage after the lamp is replaced, so power consumption is suppressed. Adjust automatically. As a result, the power consumption is controlled to gradually increase.

  Therefore, if the lighting device with the initial illumination correction function is handled in a fixed manner (for example, average power) like a device with a constant power consumption, the calculation error of the power consumption of the lighting device is not constant, and the lamp There is a problem that a very large difference occurs depending on the time (cumulative lighting time).

  In addition, (2) In the operating environment of a lighting control system that targets a large number of lighting fixtures, it is difficult to manage counter reset of each lighting fixture, and the calculation according to the cumulative lighting time cannot be performed accurately. is there.

  The counter value of the cumulative lighting time is essential information for calculating the power consumption. In order to perform the initial illuminance correction, it is necessary to collectively manage that the counter is reset (cleared to 0) by the lighting management device. There is. However, it is assumed that the response that informs the completion of the counter reset in the luminaire should be such that the lamp replacement operator can confirm the completion of the reset like the method of visually checking the brightness of the lamp as described above. Yes. In this case, the management device of the lighting control system cannot accurately manage the reset of the counter value of the cumulative lighting time.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an illumination control system capable of calculating power consumption more accurately when using a lighting fixture with an initial illumination correction function. And It is another object of the present invention to provide an illumination control system that can appropriately manage the reset of the counter of the cumulative lighting time when the lamps of each lighting fixture are replaced.

In order to achieve the above object, a lighting control system comprising a plurality of different types of lighting fixtures having an initial illumination correction function, a control terminal for controlling the lighting fixtures, and a lighting management device for centrally managing the power consumption of the lighting fixtures in the light management unit is managed for each address of the luminaire in the control terminal of the transmission line, as a starting point the counter reset time is a date and time information is reset when the lamp replacement used in the luminaire a counter means for calculating an accumulated lighting time in the period up to the present time, the light beam attenuation characteristic correction curve showing the relationship between the power consumption and the accumulated lighting time of the dimming level for each of the lamps attached to the luminaire, the Based on the storage means for storing each type of lighting fixture, and the luminous flux attenuation characteristic correction curve stored in the storage means, Based on the correction means for gradually increasing the power consumption as the cumulative lighting time increases, the cumulative lighting time calculated by the counter means, and the power consumption corrected by the correction means, the actual generated power consumption is calculated. And a power consumption amount calculating means.

In the lighting control system, the light management system, for each address in said control terminal corresponding to the luminaire, the counter reset time, the transmission signal of the lighting control system with a manual reset operation during lamp replacement It is preferable to acquire based on the information.

  In this lighting control system, it is preferable that the lighting management device further includes an interface for editing and registering the counter reset date / time information.

  This lighting control system preferably further includes an external device capable of exchanging data files with the lighting management apparatus and having an interface for editing and registering the counter reset date and time.

In the lighting control system, wherein the storage means, said manual resetting of the control conditions set for each model of the luminaire are preferably stored in advance.

The lighting control system further includes an input device capable of registering a counter reset date and time held in the lighting management device in one operation, and the lighting management device has a registration operation performed on the input device. in the control terminal corresponding to the address of the luminaire in question, the recording of the last date and time were carried out the counter reset by generating a predetermined power supply turning on and off timing operation required for registration of the counter reset time It is preferable to do.

In the lighting control system, wherein the storage unit, a predetermined set of the power turning on and off of the timing operation conditions required for the counter resets, holds for each type of the luminaire,
Preferably, the lighting management device causes the control terminal to control the power on / off timing operation corresponding to the model based on the model information of the lighting fixture.

  In this illumination control system, it is preferable that the input device includes at least one of an operation screen for registering the counter reset date and time or a dedicated control button.

In the lighting control system, the input device is preferably set in the address of the luminaire to be controlled of the control terminal via the operation screen can be arbitrarily changed.

The lighting control system, further comprising a switch unit having a function of manual reset operation of the counter reset time with the remote control of lighting fixtures, the light management device, the occurrence of a manual reset operation at the switch unit when it is detected, it is preferable that the control in correspondence to each address of the luminaire in the terminal updates the counter reset time.

In this lighting control system, the storage means holds in advance the manual reset control condition in the switch unit for each model of the lighting fixture, and the lighting management device associates in advance with an address corresponding to the switch unit. based on the model information of the luminaire that is, it is determined whether generation pattern of the control request signal transmitted from the switching unit to the light management device matches the manual reset condition of the counter reset time, wherein It is preferable to update the counter reset date and time when the generation pattern of the control request signal matches the manual reset condition that is held in advance.

  According to the lighting control system of the present invention, the lighting management device reduces power consumption at the initial stage of lamp replacement attached to a lighting fixture with an initial illuminance correction function, and the lamp has the same brightness as the cumulative lighting time increases. In order to maintain the power consumption, a correction for gradually increasing the power consumption is performed. Since the lighting management apparatus calculates the power consumption based on the corrected power consumption and the cumulative lighting time, the power consumption can be calculated more accurately.

For this reason, when the lamp of each lighting fixture is replaced, the lighting management device can reset the counter value of the cumulative lighting time by a manual reset operation via an external device or input device.

Hereinafter, an illumination control system according to an embodiment of the present invention will be described with reference to the drawings.
(Embodiment 1)
The illumination control system according to the first embodiment will be described with reference to FIGS. The system 1 uses a so-called centralized polling system in which the lighting management device 2 collectively manages the lighting and lighting levels of a large number of lighting fixtures. The lighting control system 1 includes a lighting management device 2, an arithmetic processing circuit unit 3, a transmission master circuit unit 4, a lighting fixture 5, a relay control unit 6, a dimming control unit 7, an on / off switch unit 8, and a dimming device. A switch unit 9 and an external device 10 are provided. These are connected to each other via a signal line 11.

  The lighting management device 2 manages turning on / off and dimming of a lamp installed in the lighting fixture 5, and receives control requests from the on / off switch unit 8, the dimming switch unit 9, and the external device 10. Then, a control signal corresponding to the control request is transmitted to the relay control unit 6 and the dimming control unit 7. Moreover, the illumination management apparatus 2 records and manages the status information regarding lighting / extinguishing of the lighting fixture 5 and the status signal regarding the dimming level.

  The lighting management device 2 includes an arithmetic processing circuit unit 3 and a transmission parent circuit unit 4. The arithmetic processing circuit unit 3 acquires and manages the lighting on / off state of each lighting fixture 5 and the status information (monitoring information) related to dimming control, and calculates the lamp life time from the cumulative lighting time of the lamp attached to each lighting fixture 5. The power consumption used for the determination is calculated. The transmission parent circuit unit 4 receives a control request for the luminaire 5 from the external device 10, the on / off switch unit 8, and the dimming switch unit 9, and controls the lighting device 5 to be controlled to turn on / off or adjust the luminaire. A control signal for optical control is transmitted to the relay control unit 6 or the dimming control unit 7 of the target address.

  The lighting fixture 5 has an initial illuminance correction function, and is attached with an LED lamp, a fluorescent lamp, an incandescent lamp, and the like. The lighting fixture 5 is connected to the relay control unit 6 through a power supply line, and is connected to the dimming control unit 7 through a dimming signal line.

  The relay control unit 6 has a contact (relay switch) that receives the address information of the lighting fixture 5 and control information related to lighting on / off from the transmission parent circuit unit 4 and turns on / off the power supply from the AC power source 6a. The dimming control unit 7 receives the dimming signal indicating the dimming level (0 to 100%) for each address of the lighting fixture 5 from the transmission parent circuit unit 4 and performs dimming control of the lighting fixture 5. For example, a PWM signal is used as the dimming signal.

  The on / off switch unit 8 is a so-called wall switch, and each switch is set with an address using a predetermined number of bits, and remotely controls ON / OFF of the lighting fixture 5 corresponding to the set address. The dimming switch unit 9 has an operation button for dimming control of the lighting fixture 5 to which an address is set and an operation button for turning on and off the dimming level control. Perform remote control. The external device 10 is a computer terminal or the like that is communicably connected to the lighting management device 2 and has a GUI 10a as an interface. The signal line 11 is a wired or wireless transmission path for transmitting and receiving control requests and control signals.

  Next, the operation of the illumination control system 1 will be described. As shown in FIG. 2, when control information is generated using the on / off switch unit 8 or the like after the lamp attached to the lighting fixture 5 is replaced with a new one (base point), illumination is performed based on the control information. Turning on and off the light of the lamp provided in the instrument 5 is executed. The lighting management device 2 manages and holds the control information, the monitoring information, and the lighting time for each dimming level, and calculates and records the cumulative lighting time (2 + 2 + 2.5 + 1 + 1 + 2 = 10.5 hours in this figure).

  Next, the function of the arithmetic processing circuit unit 3 provided in the lighting management device 2 will be described. As shown in FIG. 3, the arithmetic processing circuit unit 3 includes a data correction unit 31, a data storage unit 32, a counter unit 33, a signal output unit 34, and a power consumption amount calculation unit 35.

  The data correction unit 31 corrects the power consumption according to the accumulated lighting time based on a correction curve (see FIG. 5B) calculated based on the light flux attenuation of the lighting fixture 5 that performs the initial illumination correction. For example, at the initial stage of lamp replacement, correction is made so that the rated output is 70%.

  As shown in FIG. 4, the data storage unit 32 has an address corresponding to dimming and ON / OFF control of the lighting fixture 5, a model of the lighting fixture 5, and a model having an initial illuminance correction function (by an instrument built-in button). This is a memory unit that stores a table 41 indicating the date and time of the last counter reset.

  Further, the data storage unit 32 includes a correction curve of the light flux attenuation characteristic used for correction calculation in the data correction unit 31, and a time dimming table in which the turn-off time and dimming time are scheduled in advance for automatic control of a large number of lighting fixtures. Remember. Furthermore, control information, monitoring information, and the like of the lighting fixture 5 in the lighting management device 2 are also recorded as a history.

  The counter unit 33 calculates the cumulative lighting time of each lamp using the state information of the lighting fixture 5 and the counter reset date and time immediately before being held in the table 41. The signal output unit 34 transmits a control signal related to turning on / off the lighting fixture 5 to the relay control unit 6 and transmits a dimming signal to the dimming control unit 7. The power consumption amount calculation unit 35 calculates the power consumption amount of each lamp provided in the lighting fixture 5.

  Next, the initial illuminance correction used in the illumination control system 1 will be described. FIG. 5A shows a luminous flux attenuation curve 51 showing the relationship between the cumulative lighting time and the brightness of the lighting fixture 5, and shows the nature of the lamp that gradually becomes dark as the lifetime approaches. Note that the cumulative lighting time 12000h shown in FIG.

  FIG. 5B shows a light flux attenuation characteristic correction curve (hereinafter referred to as a correction curve) 52 showing the relationship between the cumulative lighting time and power consumption when initial illuminance correction is performed, and the cumulative when initial illuminance correction is not performed. A straight line 53 indicating the relationship between the lighting time and the power consumption is shown. In the correction curve 52, the power consumption is not constant with respect to the cumulative lighting time. Therefore, in the illumination control system 1, the initial illuminance correction is performed based on the correction curve 52. For example, the lighting management device 2 is designed to maintain a luminous flux of about 70% of the rated output based on the correction curve 52 at the initial stage of lamp replacement, thereby removing excess brightness at the beginning of lamp use. Thus, the power consumption can be cut by about 15%. The correction curve 52 varies depending on the dimming level and the model of the lighting fixture 5.

  FIG. 5C is a straight line 54 showing the relationship between the light control level and the power consumption, and it can be seen that the light control level (light output) becomes brighter and the power consumption (W) increases as the light control level (light output) approaches 100%.

  Next, calculation of power consumption in the arithmetic processing circuit unit 3 of the lighting management device 2 in the lighting control system 1 will be described with reference to FIG. FIG. 6A shows a change with time of the cumulative lighting time (h) of the lamp measured by the counter unit 33 and recorded in the data storage unit 32. When the lamp is replaced, the counter for the cumulative lighting time is reset.

  FIG. 6B shows a correction curve used in the data correction means 31. In the initial stage of lamp replacement, the power consumption (W) is suppressed, and the power consumption is maintained in order to maintain the same brightness of the lamp as the cumulative usage time increases. (W) is corrected so as to gradually increase as the cumulative lighting time increases. FIG. 6C shows a change in the power consumption (W) according to the operation state in which the dimming control (characteristic at the dimming level 100%) is executed. FIG.6 (d) shows the integrating | accumulating result of the power consumption (Wh) of the lighting fixture 5 of an object period. When the integrated value of the power consumption is equal to or greater than a preset value, it can be determined that it is time to replace the lamp.

As described above, in the lighting control system 1 according to the first embodiment, the power consumption of the lighting fixture 5 with the initial illuminance correction function is controlled and monitored by the model of the lighting fixture 5 and the transmission signal. It can be handled variably according to the cumulative lighting time determined based on the information. For this reason, the lighting management apparatus 2 can calculate the integrated value of the power consumption in each lighting fixture 5 more accurately, and can grasp the lifetime of the lamp attached to the lighting fixture 5 more accurately.

(Embodiment 2)
The illumination control system according to the second embodiment will be described with reference to FIG. The lighting management device 2 of the system 1 records the data of the lighting fixture 5 in the data storage unit 32 in association with each address of the control load terminal (relay control unit 6 or dimming control unit 7) on the transmission line. to manage. In addition, the lighting management device 2 sets the “counter reset date / time” of the cumulative lighting time of the lighting fixture 5 on the transmission signal of the lighting control system 1 accompanying a manual reset operation such as a predetermined power on / off operation at the time of lamp replacement. Acquire and manage based on the information. In the illumination control system 1 according to the second embodiment, the same reference numerals are given to the same processing units as those in the first embodiment, and the detailed description thereof is omitted.

Next, a method for calculating the power consumption of the lighting fixture 5 in the lighting control system 1 according to the second embodiment will be described. First, the counter unit 33 of the lighting management device 2 stores the “counter reset date / time” stored in the data storage unit 32 for each address of the relay control unit 6 and the dimming control unit 7 on transmission corresponding to the lighting fixture 5. as a base point, to calculate the cumulative lighting time up to the current date and time.

  The lighting management device 2 holds and manages a correction curve 52 based on the power consumption and cumulative lighting time for each dimming level held in the data storage unit 32 for each model of the lighting fixture 5. In addition, the lighting management device 2 has a function of additionally creating and editing data for each model of the lighting fixture 5 and transmitting and receiving various data files to and from the external device 10. The lighting management device 2 may include a GUI 10a that is an interface for editing and registering the counter reset date / time information of each lighting fixture 5.

The data correction unit 31 of the light management device 2, and the cumulative lighting time as calculated in the counter unit 33, from the correction curve 52 of the power consumption models of the lighting apparatus 5, by using the calculation method shown in FIG. 6 The actual power consumption for each lamp attached to the lighting fixture 5 is calculated.

  As described above, in the lighting control system 1 according to the second embodiment, even in the lighting fixture 5 whose power consumption varies depending on the cumulative lighting time, the cumulative lighting time is calculated from the counter reset date and time by a predetermined manual reset. it can. Accordingly, the lighting management device 2 can accurately calculate the power consumption based on the state information on the transmission communication by using the information on various characteristics of the lighting fixture 5 associated in advance.

  Further, in the lighting control system 1, even when the lamp is replaced with a non-new lamp, the counter value for each lighting fixture 5 is derived by deriving the cumulative lighting time by directly inputting the counter reset date and time by manual reset using the external device 10 or the GUI 10a. Can be reset. In the case where the transmission parent circuit unit 4 is separate from the lighting management device 2, even if the lighting management device 2 is installed later, the power consumption can be similarly set by manually setting values such as the reset date and time. Can be calculated.

(Embodiment 3)
As shown in FIG. 8, the lighting management apparatus 2 of the lighting control system 1 according to the third embodiment enables a “manual reset” operation for registering “counter reset date / time” information for each address. This manual reset operation is set in the lighting management device 2 so that a predetermined power on / off timing control is generated by operating the external device 10 or the dedicated input device 12 only once. That is, the lighting management device 2 generates predetermined power on / off timing control for performing counter reset via the relay control unit 6 and the dimming control unit 7 of the target address to be connected for communication. The power on / off timing is, for example, ON for 1 second or more, 3 times OFF operation for 3 seconds or more, and is different depending on the model of the lighting fixture 5.

  The input device 12 is a dedicated input device communicably connected in the illumination control system 1 and includes a dedicated control button (switch) for manual reset and a GUI (operation screen) for manual input. Moreover, the setting of the address of the lighting fixture 5 to be controlled can be arbitrarily changed using the input device 12.

  The lighting management device 2 sets a predetermined series of power on / off timing conditions necessary for the counter reset so that the lighting on / off timing required for the model is controlled in conjunction with the model selection of the lighting fixture 5. Can be maintained and managed for each model. In addition, the arithmetic processing circuit unit 3 of the lighting management device 2 stores the last date and time when the counter reset of the target address is performed in the data storage unit 32 when the counter reset control by the operation of the dedicated control button of the input device 12 is successful. Record and manage.

  Furthermore, when the counter reset control fails (or the state change history does not match), the input device 12 notifies the user of the failure using a warning sound or a display unit. Further, the input device 12 can be set so that the counter reset operation cannot be performed when the timing of control overlaps with the schedule control or the like in the same lighting control system 1.

  As described above, according to the lighting control system 1 according to the third embodiment, when the lamp of the lighting fixture 5 is replaced, the external device 10 and the input device 12 are provided with a dedicated control button for resetting the counter and a GUI. This makes it possible to obtain work stability that does not depend on skills in manual counter resetting work and to improve the estimation accuracy of work man-hours. Further, the input work for recording and managing the counter reset date and time by the lighting management device 2 can be automated in conjunction with the counter reset control operation. Furthermore, since a work history remains in the input device 12 or the like, it is possible to check and reduce work leakage. Furthermore, the worker can work without moving the place, and man-hours and labor costs can be reduced.

  In addition, in order to manage the counter value (cumulative lighting time from the time of replacement with a new fluorescent tube) at the time of initial illuminance correction, it is reset at the time of performing the counter reset by manual operation at the local wall switch If the date and time can be manually input to the lighting management device 2, the lighting management device 2 can calculate based on the cumulative value of the lighting time after this date and time.

  However, in this case, there are the following problems. That is, when counter reset is performed, some restrictions are imposed on the procedure and operation in order to prevent misidentification (prevention of accidental occurrence) with a normal lighting operation. For this reason, when performing manually from a local wall switch, depending on an operator's skill, there exists a possibility that it cannot implement well. Further, in an operating environment where the lighting control system 1 is introduced, a large number of lighting fixtures 5 are often targeted, so that the corresponding address is moved more in front of the wall switch in order to support a large number of switches. . Furthermore, the counter reset operation and the input management work to the lighting management device 2 also increase in proportion. Furthermore, there is a possibility that work leakage occurs due to the worker's forgetfulness.

(Embodiment 4)
As shown in FIG. 9, the lighting control system 1 according to the fourth embodiment has an on / off switch unit 8 (or dimming switch) on the transmission system to register “counter reset date / time” information for each address. It is possible to generate a “manual reset” operation in part 9).

  In the lighting management device 2, the manual operation in the on / off switch unit 8 is manually reset based on the model information of the lighting fixture 5 held in the data storage unit 32 and associated in advance with the address of the on / off switch unit 8. It is determined whether or not the condition is met, and is distinguished from a normal lighting control operation. The manual reset operation in the on / off switch unit 8 is, for example, a double quick within 1 second or a long press for 3 seconds or more.

  The conditions (timing) of manual reset control for each model of the lighting fixture 5 are stored in advance in the data storage unit 32 of the lighting management device 2. When the lighting management device 2 matches the counter reset request accompanying lamp replacement based on the generation pattern of the “control request signal” from the on / off switch unit 8 to the lighting management device 2, the data storage unit The counter reset date and time recorded in 32 is updated.

  For models that have a function that allows the counter to be reset inside the lighting management device 2 by automatic reset when lamp replacement is not performed systematically and is used until the end of the lamp life, along with lamp replacement work, The counter reset date and time can be manually input by the management apparatus 2, or the method of the third embodiment can be implemented separately.

  As described above, in the lighting control system 1 according to the fourth embodiment, when lamp replacement is performed in an operation in which systematic replacement is performed before the lifetime of the lamp, the corresponding wall switch is turned on / off. A counter reset operation can be performed using the switch unit 8. With this, even if the operator does not know the address value itself on the transmission of the luminaire 5 or the switch that has actually been replaced, the lighting management device 2 can automatically manage the accumulated lighting time, Accurate power consumption can be calculated.

(Embodiment 5)
The illumination control system according to the fifth embodiment will be described with reference to FIG. Since the lighting control system 1 registers “counter reset date / time” information for each address between the transmission system and the lighting management device 2, the “manual reset” operation is generated in the on / off switch unit 8 on the transmission system. Is provided. The transmission parent circuit unit 4 is separate from the lighting management device 2.

  The interface terminal 13 holds an address number and model information in the relay control unit 6 and the dimming control unit 7 corresponding to the lighting fixture 5 connected from the lighting management device 2. In addition, the interface terminal 13 has a manual reset control condition (timing) for each model of the lighting fixture 5 in advance. Whether the interface terminal 13 matches the manual reset condition of the model based on the control from the transmission parent circuit unit 4 to the relay control unit 6 and the dimming control unit 7 and the model information previously associated with the switch address. It is determined whether or not the load control operation is normal.

  Further, the interface terminal 13 always collects the generation pattern of the “control signal” to the terminal address corresponding to the lighting fixture 5 that performs the initial illuminance correction, and resets the counter to the lighting management device 2 when the conditions match. Inform. The lighting management device 2 receives the counter reset notification from the interface terminal 13 and updates the counter reset date and time of the lighting fixture 5 corresponding to the corresponding address.

  As described above, in the lighting control system 1 according to the fifth embodiment, in addition to the effects in the fourth embodiment described above, the existing transmission parent circuit unit 4 is connected to the lighting management device 2 via the interface terminal 13. Even if it is a separate device, it is possible to accurately calculate the power consumption. The present invention is not limited to the configuration of the embodiment described above, and various modifications can be made without departing from the spirit of the invention.
