[0003]
As shown in FIG. 25, the management system of the first prior art, as shown in FIG. 25, has a gateway 6 for bridging signals between the general monitoring device 1PA, various subsystems (2PA, 3, 4, 5), and the OA network system 7. Are connected to the wiring L1 of the building equipment network, and the power consumption management and the operation record management of each subsystem are performed by the integrated monitoring device 1PA.
[0004]
As shown in FIG. 26, the integrated monitoring device 1PA includes a building network interface 11 for transmitting / receiving signals to / from each subsystem, a power consumption monitoring unit 12PA for monitoring power consumption of each subsystem, and a power consumption of each subsystem. A power target value management unit 14 that sets a target value of the power supply, a control determination unit 15 that calculates a control operation pattern based on the operation state of each subsystem (power reduction), operation state information of each subsystem, and power consumption. A monitoring unit 12PA, a control unit 10PA that generates an instruction signal to each subsystem based on the calculation results of the power target value management unit 14 and the control determination unit 15 performs power monitoring control of each subsystem.
[0005]
As shown in FIG. 25, the subsystem includes a lighting subsystem 2PA including a lighting fixture 21PA and a lighting controller 20PA for controlling the lighting fixture 21PA (see FIG. 27), an air conditioner and an air conditioning controller for controlling the same. There is an air conditioning subsystem 3 composed of a controller, a crime prevention subsystem 4 composed of crime prevention equipment and a security control controller for controlling the same, and a disaster prevention subsystem 6 composed of disaster prevention equipment and a disaster prevention control controller for controlling the same. .
[0006]
The general operation of the management system having such a configuration will be described. In the integrated monitoring device 1PA, the power consumption monitoring unit 12PA monitors the power consumption of each subsystem, and the power consumption of the subsystem is set to a predetermined power amount. If it exceeds, a power reduction request is issued. When receiving the power reduction request via control unit 10PA, power target value management unit 14 sets a power target value for reducing power consumption of each subsystem. The control determination unit 15 calculates a control operation pattern for realizing the power target value set by the power target value management unit 14 for each subsystem, and outputs the control operation pattern to the control unit 10PA. The control unit 10PA generates a power reduction control signal for executing power reduction control in each subsystem based on the control operation pattern, and outputs the power reduction control signal via the building network interface 11.
[0007]
Upon receiving the power reduction control signal from the integrated monitoring device 1PA, each subsystem performs power reduction control of its own load device in accordance with the content included in the power reduction control signal. After the power reduction control, information on the power consumption in the subsystem is fed back to the integrated monitoring device 1PA, and the power reduction control is performed in each subsystem until the reduction of the power target value is achieved.
[0008]
In FIG. 25, at least one subsystem of the same type constitutes one load control system. In this case, each subsystem in the figure is read as a load control system. For example, a lighting control system is configured by at least one lighting subsystem 2PA, and an air conditioning control system is configured by at least one air conditioning subsystem 3. In the example of FIG. 27, a lighting control system is configured by a plurality of lighting subsystems 2PA.
[0009]
(Second conventional technology)
FIG. 28 is a configuration diagram of a management system according to the second prior art, and FIGS. 29 and 30 are explanatory diagrams of the operation of the management system.
[0010]
As shown in FIG. 28, the management system of the second prior art is configured by connecting the same general monitoring device 1PA and a plurality of lighting subsystems 2PA to the wiring L1 of the building equipment network as in the first prior art. I have.
[0011]
The lighting subsystem 2PA includes a plurality of lighting devices 21PA and a lighting control controller 20PA that controls lighting, extinguishing, or dimming of the lighting devices 21PA.
[0012]
The lighting control controller 20PA includes a building network interface 201 for transmitting and receiving signals to and from the integrated monitoring device 1PA, a signal transmitting and receiving unit 202 for transmitting and receiving signals to and from each lighting fixture 21PA in the lighting subsystem 2PA to which the lighting control controller 20PA belongs, and a control operation pattern. An illumination control signal generation unit 203 that generates an illumination control signal that meets the requirements, and an arithmetic processing unit 200PA that performs processing such as overall control of the illumination controller 20PA.
[0013]
Next, the operation of the management system of the second prior art will be described. In the normal state, the integrated monitoring device 1PA monitors the power consumption of each subsystem (load control system) by the power consumption monitoring unit 12PA (S100 in FIG. 29). Then, when each subsystem operates with power consumption equal to or less than the specified value set in the power consumption monitoring unit 12PA, the comprehensive monitoring device 1PA performs only power monitoring, and performs power reduction control and operation for each subsystem. Do not execute processing such as a status return request.
[0014]
On the other hand, in the integrated monitoring device 1PA, when each subsystem operates with power consumption exceeding the specified value, the power consumption monitoring unit 12PA issues a power reduction request, and shifts to the first step of power reduction control. . When receiving the power reduction request, control unit 10PA instructs power target value management unit 14 to set a power reduction target. The power target value management unit 14 sets a power target value W_Light1 for reducing the power consumption of each lighting subsystem 2PA (S101). The control determination unit 15 calculates a control operation pattern for lowering the lighting level to 90% in order to achieve the power target value W_Light1, and outputs the control operation pattern to the control unit 10PA (S102). The control unit 10PA generates a lighting power reduction instruction for lowering the lighting level of the lighting fixture 21PA in the lighting subsystem 2PA to 90% based on the control operation pattern, and outputs the instruction via the building network interface 11 (S103). ).
[0015]
When the lighting control controller 20PA in each lighting subsystem 2PA receives a lighting power reduction instruction from the integrated monitoring device 1PA at the building network interface 201, the lighting control controller 20PA performs signal processing at the arithmetic processing unit 200PA and sends the signal to the lighting control signal generation unit 203. On the other hand, an instruction to generate a lighting control signal for setting the lighting level of the lighting fixture 21PA to 90% is issued. The illumination control signal generation unit 203 receives the instruction, generates an illumination control signal, and outputs it via the signal transmission / reception unit 202.
[0016]
Upon receiving the lighting control signal, each lighting fixture 21PA connected to the lighting control controller 20PA controls the lamp power so that the lighting level becomes 90% (S104). On the other hand, the lighting control controller 20PA controls the lighting load after the lighting control. The power consumption value w_lc is calculated and fed back to the integrated monitoring device 1PA via the building network interface 201 (S105).
[0017]
The control unit 10PA in the integrated monitoring device 1PA calculates an addition value w of the lighting load power consumption value w_lc fed from the lighting control controller 20PA in each lighting subsystem 2PA, and is set by the power target value management unit 14. It is compared with the target power value W_Light1 (S106). As a result, when the total w of the lighting load power consumption values is larger than the power target value W_Light1 of each lighting subsystem 2PA, it is determined that the reduction of the power target value has not been achieved (S107), and the second power reduction control is performed. Move to step. On the other hand, when the total w of the lighting load power consumption values is equal to or less than the power target value W_Light1, it is determined that the reduction of the power target value has been achieved (S108), and the current operation state is received until a power reduction release instruction is received from the comprehensive monitoring device 1PA. Is held (S109). Even when w ≦ W_Light1 and the reduction of the power target value is achieved, if further power reduction is required depending on the power monitoring status of each subsystem, the process proceeds to the second step of the power reduction control.
[0018]
If w> W_Light1 (the sum w of the lighting load power consumption value is larger than the power target value W_Light1), it is determined that the reduction of the power target value has not been reached, and the process proceeds to the second step of the power reduction control. Then, the control determination unit 15 calculates a control operation pattern for lowering the lighting level to 80%, and the control unit 10PA generates a lighting power reduction instruction for instructing the lighting level 80%, and outputs it via the building network interface 11 ( S110). When the lighting control controller 20PA in each lighting subsystem 2PA receives the lighting power reduction instruction output from the integrated monitoring device 1PA at the building network interface 201, it generates a lighting control signal and outputs the signal to each lighting fixture 21PA under control. (S111). Upon receiving the lighting control signal, the lighting fixture 21PA controls the lamp power so that the lighting level becomes 80% (S112), while the lighting controller 20PA calculates the lighting load power consumption value w_lc after the lighting control to obtain the overall value. Feedback is provided to the monitoring device 1PA (S113).
[0019]
The control unit 10PA in the integrated monitoring device 1PA calculates an addition value w of the lighting load power consumption value w_lc fed back from the lighting control controller 20PA in each lighting subsystem 2PA, and is set by the power target value management unit 14. It is compared with the power target value W_Light1 (S114). As a result, when the sum w of the lighting load power consumption value is larger than the power target value W_Light1, it is determined that the reduction of the power target value has not been reached (S115), and the process proceeds to the third step of the power reduction control. On the other hand, when the total sum w of the lighting load power consumption value is equal to or smaller than the power target value W_Light1, it is determined that the reduction of the power target value has been achieved (S116), and the current operation state is received until a power reduction release instruction is received from the comprehensive monitoring device 1PA. Is held (S117). Even when w ≦ W_Light1 and the reduction of the power target value is achieved, if further power reduction is required depending on the power monitoring status of each subsystem, the process proceeds to the third step of the power reduction control.
[0020]
When w ≦ W_Light1 (when the total w of the lighting load power consumption values is equal to or less than the power target value W_Light1), it is determined that the reduction of the power target value has been achieved, and the operation state of the lighting level of 90% is held (S109). Thereafter, when there is no need for power reduction due to the power consumption monitoring status of each subsystem of the integrated monitoring device 1PA, the control unit 10PA generates a power reduction release signal and outputs it via the building network interface 11. Upon receiving the power reduction release signal, the lighting control controller 20PA in each lighting subsystem 2PA controls the lighting of the lighting fixture 21PA so as to return the lighting state to the normal 100% lighting.
[0021]
If further power reduction is required due to the power consumption monitoring status of the general congratulatory apparatus 1PA (S109a), the process proceeds to the second step of power reduction, and the control unit 10PA sends the power target value management unit 14 Instruct the user to set a power reduction target. The power target value management unit 14 sets a power target value W_Light2 for reducing the power consumption of each lighting subsystem 2PA (S109b). The control determining unit 15 calculates a control operation pattern for lowering the lighting level to 80% to output the target power value W_Light2 set by the target power value management unit 14 to the control unit 10PA (S110). The control unit 10PA generates a lighting power reduction instruction for lowering the lighting level of the lighting fixture 21PA to 80% based on the control operation pattern, and outputs the instruction via the building network interface 11.
[0022]
When the lighting control controller 20PA in each lighting subsystem 2PA receives a lighting power reduction instruction from the integrated monitoring device 1PA at the building network interface 201, the lighting control controller 20PA performs signal processing at the arithmetic processing unit 200PA and sends the signal to the lighting control signal generation unit 203. On the other hand, an instruction to generate a lighting control signal for setting the lighting level of the lighting fixture 21PA to 80% is issued (S111). The illumination control signal generation unit 203 receives the instruction, generates an illumination control signal, and outputs it via the signal transmission / reception unit 202. Upon receiving the lighting control signal, each lighting fixture 21PA connected to the lighting control controller 20PA controls the lamp power so that the lighting level becomes 80% (S112). On the other hand, the lighting controller 20PA controls the lighting load after the lighting control. The power consumption value w_lc is calculated and fed back to the integrated monitoring device 1PA via the building network interface 201 (S113).
[0023]
The control unit 10PA in the integrated monitoring device 1PA calculates an addition value w of the lighting load power consumption value w_lc fed back from the lighting control controller 20PA in each lighting subsystem 2PA, and is set by the power target value management unit 14. A comparison is made with the power target value w_Light2 (S114). As a result, when the total w of the lighting load power consumption values is larger than the power target value W_Light2 of each lighting subsystem 2PA, it is determined that the reduction of the power target value has not been reached (S115), and the third power reduction control is performed. Move to step. On the other hand, if the total w of the lighting load power consumption values is equal to or less than the power target value w_Light2, it is determined that the reduction of the power target value has been achieved (S116), and the current operation state is changed until a power reduction release instruction is received from the comprehensive monitoring device 1PA. It is held (S117). Even when w ≦ W_Light2 and the reduction of the power target value is achieved, if further power reduction is required depending on the power monitoring status of each subsystem, the process proceeds to the third step of the power reduction control.
[0024]
Also in the third step, the power of each lighting subsystem 2PA is controlled by performing lamp power control to reduce the lighting level of the lighting fixture 21PA to 70% by the same procedure as the first step and the second step (S118 to S121). Reduction control is performed (see FIG. 30). However, the lamp power control for lowering the lighting level of the lighting fixture 21PA to 70% is held until the general monitoring device 1PA notifies the cancellation of the power reduction (S122).
[0025]
In addition, in various subsystems other than the illumination subsystem 2PA, similarly to the above, the power reduction control of the load device is performed based on the power reduction instruction calculated by the integrated monitoring device 1PA.
[0026]
(3rd prior art)
In the management system according to the third related art, similarly to the second related art, the power consumption monitoring unit in the comprehensive monitoring device monitors the power consumption of each subsystem (load control system), and the power consumption of each subsystem is determined in advance. If the specified amount of power is exceeded, a power reduction request is issued. Upon receiving the power reduction request from the power consumption monitoring unit via the control unit, the power target value management unit sets a power target value for reducing the power consumption of each subsystem. The control determination unit calculates, for example, a control operation pattern for uniformly reducing the lighting level for realizing the power target value set by the power target value management unit by 10% for each lighting subsystem, and outputs the control operation pattern to the control unit. . The control unit generates a power reduction control signal for controlling each lighting subsystem based on the calculation result of the control operation pattern, and outputs the power reduction control signal via the building network interface.
[0027]
When the lighting controller in each lighting subsystem receives the power saving control signal from the integrated monitoring device, the lighting fixture connected to the lighting controller as shown in FIG. 31 according to the content of the power reducing control signal. Of the lighting level is uniformly reduced by 10%, and the power reduction control is performed until the reduction of the power target value is achieved.

[Problems to be solved by the invention]
In the first prior art, the functions of power monitoring and power reduction control are concentrated on the general monitoring device. When the system scale becomes large, the power consumption monitoring of each subsystem and the calculation at the time of calculating the control operation pattern for power reduction are performed. In the processing, there is a problem that the load on the integrated monitoring device becomes heavy. Further, to realize the above functions, the power consumption monitoring unit, the control determination unit, and the control unit in the integrated monitoring device require sophisticated arithmetic processing functions, and the integrated monitoring device itself becomes expensive.
[0031]
In the power reduction control of the second related art, the operation determination function of the power reduction control is concentrated on the general monitoring device, as in the first related art. The contents of the power reduction control of each subsystem such as lighting and air conditioning are all calculated in the integrated monitoring device, and each subsystem performs control in accordance with the instruction of the integrated monitoring device. For this reason, when the system scale becomes large, there is a problem that the load on the integrated monitoring device becomes heavy in the operation processing when monitoring the power consumption of each subsystem and calculating the control operation pattern for power reduction. Occurs.

Further, in the lighting equipment in the lighting subsystem, since all lighting equipment performs the same control in accordance with an instruction from the comprehensive monitoring device, it is not possible to perform optimal power control for the operating state and installation state of each lighting equipment. However, it cannot be said that efficient reduction of the lighting power is necessarily performed. In order to determine the power control based on the operating state of each lighting fixture, it is necessary to feed back the operating state information from each of the lighting fixtures that are the end loads of the lighting subsystem to the integrated monitoring device. However, in this case, as the communication traffic of the building equipment network increases, the general monitoring device needs to perform an arithmetic process on a huge amount of information, and there is a problem that a great burden is imposed on the general monitoring device.
[0033]
In addition, since all lighting fixtures perform lighting control in the same way, in places where lighting fixtures subject to power reduction control are installed, the illuminance is reduced and the atmosphere in the surrounding space is worsened. May decrease.
[0034]
In the third related art, as shown in FIG. 31, when a shared place such as a rest room or a corridor and an office are mixed, even in the office where it is necessary to secure the illuminance in the work, the illuminance is slightly increased. Even if it is lowered, the same lighting control is performed even in a common place where there is little problem with work, so for those who are working in the office, the visibility environment changes due to the decrease in illuminance, and there was a problem that the work environment deteriorated . If the illuminance lowers the atmosphere of the surrounding space, the psychological effect is adversely affected, and the productivity of the work is reduced.
[0035]
The present invention has been made in view of the above circumstances, and does not require a high-cost comprehensive monitoring device without increasing the load on the comprehensive monitoring device even when the system scale is large. The purpose is to provide a management system.

The arithmetic processing unit 200 performs processing such as overall control of the lighting subsystem 2 through arithmetic processing. For example, when a load power consumption value is acquired from each lighting fixture 21 via the signal transmitting / receiving unit 202, the load consumption A power value is added to obtain a subsystem power consumption value, and a process of transmitting the subsystem power consumption value to the integrated monitoring device 1 via the building network interface 201 is performed. When the power reduction instruction signal from the integrated monitoring device 1 is received by the building network interface 201, a process for creating the control operation pattern is executed in cooperation with the power target value management unit 204 and the control determination unit 205. Is done. Further, when the illumination control signal generation unit 203 generates an illumination control signal that matches the control operation pattern, a process of transmitting the illumination control signal to each lighting fixture 21 via the signal transmission / reception unit 202 is executed.
[0058]
Next, the operation of the management system of the first embodiment will be described. In each lighting fixture 21 of each lighting subsystem 2, information on the load power consumption value is created from the current lighting level detected by the lighting level detection circuit 213 and the rated lamp power consumption value, and the information is transmitted via the signal transmission / reception unit 211. It is transmitted to the lighting control controller 20.
[0059]
When the information of the load power consumption value from each lighting fixture 21 in the lighting subsystem 2 is acquired via the signal transmitting / receiving unit 202 in the lighting control controller 20 of each lighting subsystem 2, the load power consumption values are added. By doing so, a subsystem power consumption value is obtained. Thereafter, the subsystem power consumption value is transmitted to the integrated monitoring device 1 via the building network interface 201.
[0060]
When the subsystem power consumption values from the respective subsystems such as the lighting subsystem 2 are acquired via the building network interface 11 in the integrated monitoring device 1, the system power consumption values are calculated by summing the subsystem power consumption values. Is calculated. Thereafter, it is determined whether to issue a power reduction request according to whether the system power consumption value exceeds the specified power consumption value. When it is determined that the power reduction request is not issued, the current operation state of the management system is maintained. On the other hand, when it is determined that the power reduction request is issued, a power reduction instruction signal is generated. The information is transmitted to each subsystem via the building network interface 11. Here, it is assumed that, for example, a power reduction instruction signal of power reduction level 1 is generated and transmitted.
[0061]
In the lighting control controller 20 of each lighting subsystem 2, when the power reduction instruction signal of the power reduction level 1 from the integrated monitoring device 1 is received by the building network interface 201, the power reduction control mode corresponding to the power reduction level 1 is set. Transition. Then, under the cooperation of the instruction, transfer, signal processing, and the like of the arithmetic processing unit 200, the subsystem target value for the power reduction level 1 is set by the power target value management unit 204, and the control determination unit 205 An individual target value smaller than the current load power consumption value is obtained for at least a part of each lighting fixture 21 in the illumination subsystem 2, and a control operation pattern for operating at the individual target value is created. Subsequently, an illumination control signal that matches the control operation pattern is generated by the illumination control signal generation unit 203, and transmitted from the signal transmission and reception unit 202 to each lighting fixture 21.
[0062]
In each of the lighting fixtures 21 of each of the lighting subsystems 2, when the lighting control signal from the lighting control controller 20 is received by the signal transmitting / receiving unit 211, the control unit 210 according to the control content (control operation pattern) included in the lighting control signal. By controlling the lighting device 212, the lamp load LD is turned on, turned off, or dimmed. At this time, the load power consumption value of at least a part of each lighting fixture 21 in each lighting subsystem 2 is reduced to be the individual target value.
[0063]
Subsequently, the control unit 210 creates information on the load power consumption value from the current lighting level detected by the lighting level detection circuit 213 and the rated lamp power consumption value. Sent to. The transmission processing of the load power consumption value information can be omitted if the rated lamp power consumption value has already been transmitted to the lighting control controller 20.
[0064]
The lighting control controller 20 of each lighting subsystem 2 calculates a subsystem power consumption value from the latest load power consumption value and determines whether or not the power consumption value is equal to or less than the subsystem target value. Here, when information on the load power consumption value is transmitted from each lighting fixture 21, the subsystem power consumption value is calculated by adding the load power consumption values. On the other hand, when the control content included in the lighting control signal for each lighting fixture 21 is the dimming rate and the rated lamp power consumption value of each lighting fixture 21 is held, the dimming is performed to the rated lamp power consumption value. The load power consumption value is calculated by multiplying by the rate, and the subsystem power consumption value is calculated by adding the load power consumption value of each lighting fixture 21.
[0065]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200 determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1. After that, when a power reduction release signal is transmitted from the comprehensive monitoring device 1, each lighting fixture 21 is turned on at a power consumption (for example, a rated lamp power consumption value) preset for normal operation in accordance with the power reduction release signal. Operate.
[0066]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200 determines that the target is not attained, or if it is switched to the power reduction level 2, the power reduction corresponding to the power reduction level 2 Move to control mode. Then, the subsystem target value for the power reduction level 2 is set by the power target value management unit 204, and the control determination unit 205 adjusts at least a part of each lighting fixture 21 in the lighting subsystem 2 in accordance with the subsystem target value. An individual target value smaller than the current load power consumption value is obtained, and a control operation pattern for operating with the individual target value is created. Subsequently, an illumination control signal that matches the control operation pattern is generated by the illumination control signal generation unit 203, and transmitted from the signal transmission and reception unit 202 to each lighting fixture 21.
[0067]
In each of the lighting fixtures 21 of each of the lighting subsystems 2, when the lighting control signal from the lighting control controller 20 is received by the signal transmitting / receiving unit 211, the control unit 210 according to the control content (control operation pattern) included in the lighting control signal. By controlling the lighting device 212, the lamp load LD is turned on, turned off, or dimmed. At this time, the load power consumption value of at least a part of each lighting fixture 21 in each lighting subsystem 2 is further reduced so as to be the individual target value.
[0068]
The lighting control controller 20 of each lighting subsystem 2 calculates a subsystem power consumption value from the latest load power consumption value and determines whether or not the power consumption value is equal to or less than the subsystem target value.
[0069]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200 determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1. After that, when a power reduction release signal is transmitted from the comprehensive monitoring device 1, each lighting fixture 21 operates with power consumption preset for normal operation in accordance with the power reduction release signal.
[0070]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200 determines that the target is not achieved or is switched to a power reduction level of 3 or more, the power reduction level of 3 or more To the power reduction control mode corresponding to the above, and the same processing as described above is executed. When the power reduction level is the maximum level of the power reduction amount, the operation state of the maximum power reduction level is maintained until the power reduction cancellation signal is transmitted from the comprehensive monitoring device 1 as in step S122 of FIG. May be maintained.
[0071]
As described above, according to the first embodiment, the lighting control controller 20 included in each lighting subsystem 2 supplies the current load power consumption value to at least a part of each lighting fixture 21 in the lighting subsystem 2 to which the lighting subsystem 2 belongs. Since the individual target value smaller than that is obtained and the control is performed so as to operate with the individual target value, the comprehensive monitoring device 1 does not need to perform the specific control of each lighting fixture 21 only by giving the power reduction instruction. Therefore, the load of the arithmetic processing of the integrated monitoring device 1 can be reduced, and the configuration can be simplified and the cost can be reduced. This makes it possible to provide a management system or the like that does not require a high-cost integrated monitoring device without increasing the load on the integrated monitoring device even when the system scale is increased.

[0077]
The lighting device 212A turns on / off or dims the lamp load LD according to the control of the control unit 210A, similarly to the lighting device 212 of the first embodiment. When light is emitted, the lamp load LD can be adjusted in accordance with the visibility of human eyes (see FIG. 5).
[0078]
The control unit 210A is different from the control unit 210 of the first embodiment in that when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the lighting control The lighting device 212A is controlled according to the control content included in the signal. Further, based on the current lighting level detected by the lighting level detection circuit 213 and the previously held rated lamp power consumption value of the lamp load LD, information on the power consumption value (load power consumption value) of the lighting fixture 21A is obtained. Then, a process of transmitting to the lighting control controller 20A via the signal transmitting and receiving unit 211 as the operating state information together with the own lighting fixture address is executed.
[0079]
The transmission process of the operation state information is executed when a lighting level response request is received from the illumination control controller 20A via the signal transmission / reception unit 211. Note that the lighting level response request is configured to be issued from the lighting control controller 20A in response to the response request even when the integrated monitoring device 1 issues a response request for the subsystem power consumption value to each lighting subsystem 2A. May be. Further, the above-described processing may be further periodically executed.
[0080]
As shown in FIG. 3, the lighting control controller 20A includes a building network interface 201, a signal transmission / reception unit 202, and a power target value management unit 204 in the same manner as the lighting control controller 20 of the first embodiment. The difference from the illumination control controller 20 is that the illumination control controller 20 includes an arithmetic processing unit 200A, a control determination unit 205A, and an illumination control signal generation unit 203A. In the second embodiment, since a part or all of the lighting fixtures 21A in the lighting subsystem 2A are controlled to operate at the individual target values, the power target value management unit 204 performs the control. A target value (subsystem target value) of power consumption of each of the target lighting fixtures 21A is set.
[0081]
The arithmetic processing unit 200A is different from the arithmetic processing unit 200 of the first embodiment in that when a lighting level response request is issued from the control determining unit 205A, it is transmitted to each lighting fixture 21A via the signal transmitting and receiving unit 202. After that, when the operation state information is acquired from each lighting fixture 21A via the signal transmitting / receiving unit 202, as shown in FIG. 6, the load power consumption value (“lighting level” in the figure) is associated with the lighting fixture address. Further, a process of creating the data table and passing it to the control determination unit 205A is further executed. Here, the “lighting level” shown in FIG. 6 is a ratio of the current lighting level detected by the lighting level detection circuit 213 to the rated lamp power consumption value.
[0082]
The control judging unit 205A is different from the control judging unit 205 of the first embodiment in that when a subsystem target value is set by a power target value managing unit 204, it issues a lighting level answer request, When the data table is obtained from the unit 200A, a control operation pattern is created using the data table.
[0083]
That is, using the data table, each lighting fixture 21A in the lighting subsystem 2A is classified by priority, and among the lighting fixtures 21A classified by these priorities, the lighting fixture 21A classified into at least one priority. In response to this, processing is performed in which an individual target value smaller than the current load power consumption value is obtained, and a control operation pattern for operating with the individual target value is created.
[0084]
More specifically, using a data table, as shown in FIG. 6, sorting is performed in descending order based on the current load power consumption value (“lighting level”). A process of classifying each lighting fixture 21A in the lighting subsystem 2A according to priority is executed by setting a set whose lighting level is less than 90% and equal to or higher than 80%, for example, as the second highest priority. .
[0085]
Then, in the case of the first power reduction instruction signal (power reduction level 1 in FIG. 7), among the lighting fixtures 21A classified by priority, each lighting fixture 21A classified into the first priority is given An individual target value smaller than the current load power consumption value by, for example, 10% is obtained, and a control operation pattern for operating with the individual target value is created.
[0086]
In the case of the second power reduction instruction signal (power reduction level 2) or when the target is not achieved, among the lighting fixtures 21A classified by priority, each lighting fixture 21A classified into the second highest priority However, an individual target value that is, for example, 10% smaller than the current load power consumption value is obtained, and a control operation pattern for operating with this individual target value is created.
[0087]
When the third power reduction instruction signal (power reduction level 3) or the target is not achieved, the load power consumption value is set to each lighting fixture 21A in the lighting subsystem 2A (for example, the current An individual target value that is uniformly reduced by, for example, 30% from the load power consumption value (or in total) is obtained, and a control operation pattern for operating with this individual target value is created.
[0088]
The lighting control signal generation unit 203A generates a lighting control signal that includes a lighting fixture address and matches a control operation pattern. That is, in the case of the first power reduction instruction signal, the lighting control signal includes the lighting equipment address of each lighting equipment 21A classified into the first priority, and the second power reduction instruction signal or the target unachieved. In the case of, the luminaire address of each luminaire 21A classified into the second priority is included. If the third power reduction instruction signal or the target is not achieved, the luminaire address of each luminaire 21A in the illumination subsystem 2A is included. The luminaire address is included.
[0089]
Next, the operation of the management system according to the second embodiment will be described. In each lighting fixture 21A of each lighting subsystem 2A, the power consumption value (load) of the lighting fixture 21A is determined based on the current lighting level (power consumption value) detected by the lighting level detection circuit 213 and the rated lamp power consumption value. The information of the power consumption value is transmitted to the lighting control controller 20A via the signal transmitting and receiving unit 211 as operating state information together with the lighting fixture address.
[0090]
In the lighting control controller 20A of each lighting subsystem 2A, when the operation state information from each lighting fixture 21A in the lighting subsystem 2A is acquired via the signal transmitting / receiving unit 202, the respective load power consumption values are added. A subsystem power consumption value is determined. Thereafter, the subsystem power consumption value is transmitted to the integrated monitoring device 1 via the building network interface 201.
[0091]
When the subsystem power consumption value from each lighting subsystem 2A is acquired via the building network interface 11 in the integrated monitoring device 1, the system power consumption value is calculated by summing the subsystem power consumption values. . Thereafter, it is determined whether to issue a power reduction request according to whether the system power consumption value exceeds the specified power consumption value. When it is determined that the power reduction request is not issued, the current operation state of the management system is maintained. On the other hand, when it is determined that the power reduction request is issued, a power reduction instruction signal is generated. The information is transmitted to each lighting subsystem 2A via the building network interface 11. Here, for example, it is assumed that a power reduction instruction signal of power reduction level 1 has been generated and transmitted.
[0092]
In the lighting control controller 20A of each lighting subsystem 2A, when the power reduction instruction signal of the power reduction level 1 from the comprehensive monitoring device 1 is received by the building network interface 201 (S1 in FIG. 7), it corresponds to the power reduction level 1. To the power reduction control mode. Then, the subsystem target value for the power reduction level 1 is set by the power target value management unit 204 according to an instruction from the arithmetic processing unit 200A. Subsequently, after a control operation pattern creation instruction from the arithmetic processing unit 200A, a lighting level response request is issued by the control determining unit 205A, and the lighting fixture 21A is transmitted to the lighting fixtures 21A via the signal transmitting and receiving unit 202 in cooperation with the arithmetic processing unit 200A. It is transmitted (S2).
[0093]
In each lighting fixture 21A of each lighting subsystem 2A, when a lighting level response request is received from the lighting control controller 20A via the signal transmitting / receiving unit 211, the operating state information is transmitted to the lighting control controller 20A via the signal transmitting / receiving unit 211. (S3).
[0094]
In the lighting control controller 20A of each lighting subsystem 2A, when the operation state information is obtained from each lighting fixture 21A via the signal transmission / reception unit 202, the arithmetic processing unit 200A associates the load power consumption value with the lighting fixture address. A data table is created. After that, the control determination unit 205A classifies each of the lighting fixtures 21A in the lighting subsystem 2A by priority based on the data table, and supplies the current load power consumption to the lighting fixture 21A that has been ranked first. An individual target value 10% smaller than the value is obtained, and a control operation pattern for operating with the individual target value is created. Thereafter, a lighting control signal including the lighting fixture address of the lighting fixture 21A classified into the first priority and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21A. Is performed (S4).
[0095]
In each lighting fixture 21A of each lighting subsystem 2A, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the control contents included in the lighting control signal ( The control unit 210A controls the lighting device 212A according to the control operation pattern), so that the lamp load LD is dimmed (S5). At this time, the load power consumption value of the lighting fixture 21A classified into the first priority is reduced by 10%.
[0096]
In the lighting controller 20A of each lighting subsystem 2A, the arithmetic processing unit 200A calculates the subsystem power consumption value from the latest load power consumption value, and determines whether or not the subsystem power consumption value is equal to or less than the subsystem target value. (S6). If the rated lamp power consumption value has not been received, the latest load power consumption value shall be determined by issuing a lighting level response request or by transmitting the operating state information periodically or automatically. May be obtained.
[0097]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200A determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1. After that, when a power reduction release signal is transmitted from the integrated monitoring device 1, each lighting fixture 21A operates with power consumption preset for normal operation in accordance with the power reduction release signal.
[0098]
On the other hand, whether the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200A determines that the target is not achieved (S7), or is switched to the power reduction level 2 as described in FIG. 29 ( If S8), the process proceeds to step S9 to shift to the power reduction control mode corresponding to the power reduction level 2. Then, a subsystem target value for the power reduction level 2 is set, and an individual target value that is 10% smaller than the current load power consumption value is obtained for the lighting fixture 21A classified into the second highest priority. A control operation pattern for operating at the target value is created. If the power reduction instruction signal generated before step S1 is power reduction level 2, a subsystem target value for power reduction level 2 is set in the same procedure as steps S2 to S3. A data table is created, and based on the data table, the lighting fixtures 21A in the lighting subsystem 2A are classified by priority, and the current load is applied to the lighting fixtures 21A classified into the first and second priorities. An individual target value that is 10% smaller than the power consumption value may be obtained, and a control operation pattern for operating with the individual target value may be created.
[0099]
Subsequently, a lighting control signal including the lighting fixture address of the lighting fixture 21A classified into the second highest priority and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21A. Sent.
[0100]
In each lighting fixture 21A of each lighting subsystem 2A, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the control contents included in the lighting control signal ( The control unit 210A controls the lighting device 212A according to the control operation pattern), so that the lamp load LD is dimmed (S10). At this time, the load power consumption value of the lighting fixture 21A classified into the second highest priority is also reduced by 10%.
[0101]
In the lighting control controller 20A of each lighting subsystem 2A, the arithmetic processing unit 200A calculates the subsystem power consumption value from the latest load power consumption value, and determines whether the subsystem power consumption value is equal to or less than the subsystem target value for the power reduction level 2. Is determined (S11).
[0102]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200A determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1. After that, when a power reduction release signal is transmitted from the integrated monitoring device 1, each lighting fixture 21A operates with power consumption preset for normal operation in accordance with the power reduction release signal.
[0103]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200A determines that the target is not achieved (S12) or switches to the power reduction level 3 (S13), the process proceeds to step S14. To the power reduction control mode corresponding to the power reduction level 3. Then, a subsystem target value for the power reduction level 3 is set, and an individual target value for uniformly reducing the load power consumption value by 30% is obtained for each lighting fixture 21A in the lighting subsystem 2A regardless of the priority. Then, a control operation pattern for operating with this individual target value is created. If the power reduction instruction signal generated before step S1 is power reduction level 3, a subsystem target value for power reduction level 3 is set, and then each lighting fixture 21A in lighting subsystem 2A is set. On the other hand, for example, an individual target value for uniformly reducing the load power consumption value by 30% may be obtained, and a control operation pattern for operating with the individual target value may be created.
[0104]
Subsequently, a lighting control signal including the lighting fixture address of the lighting fixture 21A in the lighting subsystem 2A and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21A. .
[0105]
In each lighting fixture 21A of each lighting subsystem 2A, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the control contents included in the lighting control signal ( The control unit 210A controls the lighting device 212A according to the control operation pattern), so that the lamp load LD is dimmed (S15). At this time, the load power consumption value of each lighting fixture 21A is reduced by 30%.
[0106]
As described above, according to the second embodiment, each lighting fixture 21A in the lighting subsystem 2A is classified according to priority, and each lighting fixture 21A classified into at least one of the lighting fixtures 21A classified according to these priorities. Since control is performed on the appliance 21A so as to obtain an individual target value smaller than the current load power consumption value and operate the appliance at this individual target value, finer power control becomes possible.
[0107]
When classifying each lighting fixture 21A in the lighting subsystem 2A by priority, the operation state information is collected from each lighting fixture 21A, and each lighting fixture 21A is classified by priority based on the operation state information. Therefore, suitable power control according to the operation state of each lighting fixture 21A can be performed.
[0108]
Further, the load power consumption value and the lighting equipment address are collected as operating state information, and based on this, each lighting equipment 21A is classified by priority, and at least the load power consumption of each lighting equipment 21A classified by these priorities is determined. For the lighting fixtures 21A classified into the priority having the largest value, a control is performed such that an individual target value smaller than the current load power consumption value is obtained and operated with this individual target value. As described above, the power control is performed preferentially from the lighting fixture 21 </ b> A having a large power reduction effect, and the efficient power reduction control can be performed while suppressing the reduction in the overall illuminance. In addition, by performing power control for each of the lighting fixtures 21A classified into the first and second priorities, it is possible to suppress a decrease in overall illuminance as compared with the case where power control is performed for each lighting fixture 21A. The effects of changes in the visual environment are also improved.
[0109]
(Third embodiment)
FIG. 8 is a diagram showing an example of a data table used by the lighting control controller in the management system according to the third embodiment of the present invention, FIG. 9 is a diagram for explaining the principle of power consumption reduction by the lighting control controller, and FIG. It is operation | movement explanatory drawing of the management system of a form.
[0110]
The management system of the third embodiment is substantially the same as the configuration of FIGS. 3 and 4 of the second embodiment, and the cumulative lighting time (of the lighting fixture 21A) obtained from the timer circuit 214 in response to the cumulative lighting time reply request. (Accumulated lighting time since installation), the lighting equipment address is returned as operating state information, the lighting equipment address is associated with the accumulated lighting time, and a data table is created. As shown in FIG. The data of each group in the data table is sorted in ascending order based on the order, the group whose cumulative lighting time is 1000 hours or less is set as the first priority, and the group whose cumulative lighting time exceeds 1000 hours and 2000 hours or less is prioritized. The second embodiment is different from the second embodiment in that it is ranked second.
[0111]
In the third embodiment, a discharge lamp such as a fluorescent lamp is used as the lamp load LD. In this case, as shown in FIG. 9, the light output of the lamp load LD exhibits a luminous flux attenuation characteristic that decreases as the lighting time elapses. That is, in the case of the same power consumption, the light output differs depending on the accumulated lighting time, and the light output with the shorter accumulated lighting time is larger than the light output with the longer accumulated lighting time.
[0112]
Next, the operation of the management system according to the third embodiment will be described. When it is determined in the integrated monitoring device 1 that a power reduction request is issued through the same procedure as in the second embodiment, a power reduction instruction signal is generated and transmitted to each subsystem via the building network interface 11. Is done. Here, for example, it is assumed that a power reduction instruction signal of power reduction level 1 is generated and transmitted from the integrated monitoring device 1 to each lighting subsystem 2A.
[0113]
In the lighting control controller 20A of each lighting subsystem 2A, as shown in FIG. 10, when the building network interface 201 receives the power reduction instruction signal of the power reduction level 1 from the comprehensive monitoring device 1 (S21), the power is reduced. The mode shifts to the power reduction control mode corresponding to level 1. Then, a subsystem target value for the power reduction level 1 is set by the power target value management unit 204, and subsequently, a cumulative lighting time response request is issued by the control determination unit 205A, and each lighting fixture is transmitted via the signal transmission / reception unit 202. It is transmitted to 21A (S22).
[0114]
In each lighting fixture 21A of each lighting subsystem 2A, when a cumulative lighting time reply request is received from the lighting control controller 20A via the signal transmitting / receiving unit 211, the cumulative lighting time is acquired from the timer circuit 214, and the cumulative lighting time is acquired. The time and the lighting equipment address are transmitted to the lighting control controller 20A via the signal transmission / reception unit 211 as operation state information (S23).
[0115]
In the lighting control controller 20A of each lighting subsystem 2A, when the operating state information is obtained from each lighting fixture 21A via the signal transmission / reception unit 202, the arithmetic processing unit 200A associates the lighting fixture address with the accumulated lighting time and sets the data. A table is created. After that, the control determination unit 205A classifies each of the lighting fixtures 21A in the lighting subsystem 2A by priority based on the data table, and supplies the current load power consumption to the lighting fixture 21A that has been ranked first. An individual target value 10% smaller than the value is obtained, and a control operation pattern for operating with the individual target value is created. Thereafter, a lighting control signal including the lighting fixture address of the lighting fixture 21A classified into the first priority and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21A. Is performed (S24).
[0116]
In each lighting fixture 21A of each lighting subsystem 2A, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the control contents included in the lighting control signal ( The control unit 210A controls the lighting device 212A according to the control operation pattern), so that the lamp load LD is dimmed (S25). At this time, the load power consumption value of the lighting fixture 21A classified into the first priority is reduced by 10%.
[0117]
In the lighting controller 20A of each lighting subsystem 2A, the arithmetic processing unit 200A calculates the subsystem power consumption value from the latest load power consumption value, and determines whether or not the subsystem power consumption value is equal to or less than the subsystem target value. (S26). Here, the latest load power consumption value may be obtained by transmitting the rated lamp power consumption value at the time of shifting to the power reduction control mode, or by issuing a lighting level answer request, Alternatively, the information may be obtained by periodically or automatically executing a process of transmitting information on the power consumption value of the lighting fixture 21A.
[0118]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200A determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1. After that, when a power reduction release signal is transmitted from the integrated monitoring device 1, each lighting fixture 21A operates with power consumption preset for normal operation in accordance with the power reduction release signal.
[0119]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200A determines that the target has not been achieved (S27) or switches to the power reduction level 2 (S28), step S29 is performed. To the power reduction control mode corresponding to the power reduction level 2. Then, a subsystem target value for the power reduction level 2 is set, and an individual target value that is 10% smaller than the current load power consumption value is obtained for the lighting fixture 21A classified into the second highest priority. A control operation pattern for operating at the target value is created. If the power reduction instruction signal generated before step S21 is power reduction level 2, a subsystem target value for power reduction level 2 is set, and then a data table is created. Based on the priority, the lighting fixtures 21A in the lighting subsystem 2A are classified by priority, and the individual targets are 10% smaller than the current load power consumption value for the lighting fixtures 21A classified into the first and second priorities. The control operation pattern for obtaining the value and operating with the individual target value may be created.
[0120]
Subsequently, a lighting control signal including the lighting fixture address of the lighting fixture 21A classified into the second highest priority and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21A. Sent.
[0121]
In each lighting fixture 21A of each lighting subsystem 2A, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the control contents included in the lighting control signal ( The control unit 210A controls the lighting device 212A according to the control operation pattern), so that the lamp load LD is dimmed (S30). At this time, the load power consumption value of the lighting fixture 21A classified into the second highest priority is also reduced by 10%.
[0122]
In the lighting control controller 20A of each lighting subsystem 2A, the arithmetic processing unit 200A calculates the subsystem power consumption value from the latest load power consumption value, and determines whether the subsystem power consumption value is equal to or less than the subsystem target value for the power reduction level 2. Is determined (S31).
[0123]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200A determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1. After that, when a power reduction release signal is transmitted from the integrated monitoring device 1, each lighting fixture 21A operates with power consumption preset for normal operation in accordance with the power reduction release signal.
[0124]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200A determines that the target has not been achieved (S32) or switches to the power reduction level 3 (S33), step S34 is performed. To the power reduction control mode corresponding to the power reduction level 3. Then, a subsystem target value for the power reduction level 3 is set, and an individual target value for uniformly reducing the load power consumption value by 30% is obtained for each lighting fixture 21A in the lighting subsystem 2A regardless of the priority. Then, a control operation pattern for operating with this individual target value is created. If the power reduction instruction signal generated before step S21 is the power reduction level 3, a subsystem target value for the power reduction level 3 is set, and then each lighting fixture 21A in the lighting subsystem 2A is set. On the other hand, an individual target value for uniformly reducing the load power consumption value by 30% may be obtained, and a control operation pattern for operating with the individual target value may be created.
[0125]
Subsequently, a lighting control signal including the lighting fixture address of the lighting fixture 21A in the lighting subsystem 2A and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21A. .
[0126]
In each lighting fixture 21A of each lighting subsystem 2A, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20A, the control contents included in the lighting control signal ( The control unit 210A controls the lighting device 212A according to the control operation pattern), so that the lamp load LD is dimmed (S35). At this time, the load power consumption value of each lighting fixture 21A is reduced by 30%.
[0127]
As described above, according to the third embodiment, the accumulated lighting time and the lighting fixture address are collected as operation state information, and based on this, each lighting fixture 21A is classified according to priority, and each lighting fixture 21A classified according to these priorities. Among the above, at least the lighting fixture 21A classified into the priority in which the cumulative lighting time is the shortest is determined so as to obtain an individual target value smaller than the current load power consumption value and to operate with the individual target value. As can be seen from FIG. 9, in the case of the same power consumption, power control is performed preferentially from the lighting fixture 21 </ b> A having a large light output and a short cumulative lighting time, and efficient power consumption is suppressed while suppressing the overall illuminance reduction. Reduction control becomes possible. In addition, by performing power control for each of the lighting fixtures 21A classified into the first and second priorities, it is possible to suppress a decrease in the overall illuminance as compared with the case where power control is performed for each lighting fixture 21A. The effects of changes in the visual environment are also improved.

FIG. 14 is an explanatory diagram of the principle, and FIG. 14 is an explanatory diagram of the operation of the management system of the fourth embodiment.
[0129]
As shown in FIG. 11, the management system of the fourth embodiment is configured by connecting a comprehensive monitoring device 1A and a plurality of lighting subsystems 2B to a wiring L1 of a building equipment network.
[0130]
The integrated monitoring device 1A includes a building network interface 11 and a power consumption monitoring unit 12 in the same manner as the integrated monitoring device 1 of the first embodiment. And a control unit 10A.
[0131]
The building management database 13 stores floor information including an indoor layout map of the floor where each lighting subsystem 2B is installed. Further, the floor information includes data in which the block number of the indoor arrangement and the type of the arrangement place (“arrangement content” in FIG. 12) are associated with each lighting fixture address of each lighting fixture 21. The floor information may be stored for each address of the lighting control controller 20B of the lighting subsystem 2B.
[0132]
The control unit 10A is different from the control unit 10 of the first embodiment in that, when a floor information request is received from the lighting subsystem 2B via the building network interface 11, the floor information corresponding to the floor information request is transmitted to the building. A process of reading from the management database 13 and returning it is further executed.
[0133]
The lighting subsystem 2B includes a plurality of lighting devices 21 as load devices, and a lighting control controller 20B connected to these lighting devices 21 via a lighting signal line L2 and controlling each lighting device 21. I have.
[0134]
The lighting control controller 20B includes a building network interface 201, a signal transmitting / receiving unit 202, and a power target value management unit 204 in the same manner as the lighting control controller 20 of the first embodiment. The difference is that it includes an arithmetic processing unit 200B, a storage unit 206, a control determination unit 205B, and an illumination control signal generation unit 203A.
[0135]
The arithmetic processing unit 200B is different from the arithmetic processing unit 200 of the first embodiment in that, when a subsystem target value is set by the power target value management unit 204, the integrated monitoring device 1A When a floor information request is issued and thereafter floor information is acquired via the building network interface 201, the data of "indoor arrangement" is added to the lighting equipment address from the floor information and the lighting equipment address read by the control determination unit 205B. Further, a process of creating a data table in which data of “arrangement contents” are associated with each other and passing the data table to the control determining unit 205B is further executed. Note that the floor information request may include the lighting fixture address read by the control determination unit 205B, or may include the address of the lighting control controller 20B.
[0136]
The storage unit 206 stores, for example, a lighting fixture address of each lighting fixture 21 in the lighting control controller 20B.
[0137]
The control determining unit 205B differs from the control determining unit 205 of the first embodiment in that when a subsystem target value is set by the power target value managing unit 204, the control unit 205B reads the lighting fixture address from the storage unit 206, and thereafter When the data table is obtained from the arithmetic processing unit 200B, a control operation pattern is created using the data table.
[0138]
That is, using the data table, each lighting fixture 21 in the lighting subsystem 2B is classified by priority, and among the lighting fixtures 21 classified by these priorities, the lighting fixture 21 classified into at least one priority. In response to this, processing is performed in which an individual target value smaller than the current load power consumption value is obtained, and a control operation pattern for operating with the individual target value is created.
[0139]
More specifically, using the above data table, as shown in FIG. 12, the data is classified according to “arrangement contents”, and a group corresponding to a common place such as “corridor” or “rest room” is assigned a priority number. A process of classifying each lighting fixture 21 in the lighting subsystem 2B according to priority is executed with the group corresponding to the workplace (“office room” in the figure) as the second highest priority.
[0140]
Then, in the case of the first power reduction instruction signal (power reduction level 1 in FIG. 14A), among the lighting fixtures 21 classified by priority, each lighting fixture 21 classified into the first priority On the other hand, an individual target value that is, for example, 50% smaller than the current load power consumption value is obtained, and a control operation pattern for operating with the individual target value is created.
[0141]
In the case where the second power reduction instruction signal (power reduction level 2) or the target is not achieved, among the lighting fixtures 21 classified by priority, the lighting fixtures 21 classified into the second priority are also determined. Then, an individual target value that is, for example, 10% smaller than the current load power consumption value is obtained, and a control operation pattern for operating with the individual target value is created.
[0142]
In the case where the third power reduction instruction signal (power reduction level 3) or the target is not achieved, the load power consumption value of each lighting fixture 21 in the lighting subsystem 2B is changed to the current load consumption regardless of the priority. An individual target value that is uniformly reduced by, for example, 10% from the power value is obtained, and a control operation pattern for operating with the individual target value is created.
[0143]
The lighting control signal generation unit 203A generates a lighting control signal that includes a lighting fixture address and matches a control operation pattern, as in the second embodiment.
[0144]
Next, the operation of the management system according to the fourth embodiment will be described. When it is determined in the integrated monitoring device 1A that a power reduction request is issued through the same procedure as in the second embodiment, a power reduction instruction signal is generated and transmitted to each subsystem via the building network interface 11. Is done. Here, for example, it is assumed that a power reduction instruction signal of the power reduction level 1 is generated and transmitted from the integrated monitoring device 1A to each lighting subsystem 2B.
[0145]
In the lighting control controller 20B of each lighting subsystem 2B, when the power reduction instruction signal of the power reduction level 1 from the comprehensive monitoring device 1A is received by the building network interface 201 (S41 in FIG. 14A), the power reduction level Shift to the power reduction control mode corresponding to 1. Then, a subsystem target value for power reduction level 1 is set by the power target value management unit 204. Thereafter, the lighting unit address is read from the storage unit 206 by the control determination unit 205B, and a floor information request is issued to the integrated monitoring device 1A via the building network interface 201 by the arithmetic processing unit 200B.
[0146]
In the integrated monitoring device 1A, when a floor information request is received from the lighting subsystem 2B via the building network interface 11, floor information corresponding to the floor information request is read from the building management database 13 and is read. Will be replied through.
[0147]
In the lighting control controller 20B of each lighting subsystem 2B, when the floor information is acquired from the integrated monitoring device 1A via the building network interface 201, the floor information and the control determining unit 205B read the floor information by the arithmetic processing unit 200B. Based on the lighting fixture address, a data table is created in which the lighting fixture address is associated with the data of “room arrangement” and the data of “arrangement content”. After that, the control determining unit 205B classifies each of the lighting fixtures 21 in the lighting subsystem 2B by priority based on the data table, and assigns the current load consumption to the lighting fixtures 21 that are ranked first. An individual target value that is 50% smaller than the power value is obtained, and a control operation pattern for operating with the individual target value is created. Thereafter, a lighting control signal including the lighting fixture address of the lighting fixture 21 classified into the first priority and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21. Is performed (S42).
[0148]
In each of the lighting fixtures 21 of each lighting subsystem 2B, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20B, the control contents included in the lighting control signal ( The control unit 210 controls the lighting device 212 according to the control operation pattern), so that the lamp load LD is dimmed (S43). At this time, the load power consumption value of the lighting fixture 21 classified into the first priority is reduced by 50% (see FIG. 14B).
[0149]
In the lighting control controller 20B of each lighting subsystem 2B, the arithmetic processing unit 200B calculates the subsystem power consumption value from the latest load power consumption value, and determines whether the subsystem power consumption value is equal to or less than the subsystem target value. (S44). Here, the latest load power consumption value may be obtained by transmitting the rated lamp power consumption value at the time of shifting to the power reduction control mode, or by issuing a lighting level answer request, Alternatively, the information may be obtained by periodically or automatically executing a process of transmitting information on the power consumption value of the lighting fixture 21.
[0150]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200B determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1A. After that, when a power reduction cancellation signal is transmitted from the integrated monitoring device 1A, each lighting fixture 21 operates with power consumption preset for normal operation according to the power reduction cancellation signal.
[0151]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200B determines that the target has not been achieved (S45) or switches to the power reduction level 2 (S46), the process proceeds to step S47. To the power reduction control mode corresponding to the power reduction level 2. Then, a subsystem target value for the power reduction level 2 is set, and an individual target value that is 10% smaller than the current load power consumption value is obtained for the luminaire 21 classified into the second highest priority. A control operation pattern for operating at the target value is created. If the power reduction instruction signal generated before step S41 is power reduction level 2, a subsystem target value for power reduction level 2 is set, and then a data table is created. The lighting fixtures 21 in the lighting subsystem 2B are classified based on priority based on the priority, and the lighting fixtures 21 classified into the first and second priorities are respectively 50% and 10% lower than the current load power consumption value. It is also possible to obtain an individual target value smaller by% and create a control operation pattern for operating with the individual target value.
[0152]
Subsequently, a lighting control signal including the lighting fixture address of the lighting fixture 21 classified into the second highest priority and matching the control operation pattern is generated by the lighting control signal generation unit 203A. Sent.
[0153]
In each of the lighting fixtures 21 of each lighting subsystem 2B, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20B, the control contents included in the lighting control signal ( The control unit 210 controls the lighting device 212 according to the control operation pattern), so that the lamp load LD is dimmed (S48). At this time, the load power consumption value of the lighting fixture 21 classified into the second highest priority is reduced by 10% (see FIG. 4C).
[0154]
In the lighting control controller 20B of each lighting subsystem 2B, the arithmetic processing unit 200B calculates a subsystem power consumption value from the latest load power consumption value, and determines whether the subsystem power consumption value is equal to or less than the subsystem target value for the power reduction level 2. Is determined (S49).
[0155]
If the subsystem power consumption value is equal to or less than the subsystem target value, the arithmetic processing unit 200B determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1A. After that, when a power reduction cancellation signal is transmitted from the integrated monitoring device 1A, each lighting fixture 21 operates with power consumption preset for normal operation according to the power reduction cancellation signal.
[0156]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200B determines that the target has not been achieved (S50) or switches to the power reduction level 3 (S51), step S52 is performed. To the power reduction control mode corresponding to the power reduction level 3. Then, a subsystem target value for the power reduction level 3 is set, and an individual target value for further reducing the load power consumption value by 10% is obtained for each lighting fixture 21 in the lighting subsystem 2B regardless of the priority. Then, a control operation pattern for operating with the individual target value is created. If the power reduction instruction signal generated before step S41 is the power reduction level 3, a subsystem target value for the power reduction level 3 is set, and subsequently, regardless of the priority, the lighting subsystem 2B It is also possible to obtain an individual target value for further reducing the load power consumption value by 10% uniformly for each of the lighting fixtures 21 and create a control operation pattern for operating with this individual target value.
[0157]
Subsequently, a lighting control signal including the lighting fixture address of the lighting fixture 21 in the lighting subsystem 2B and matching the control operation pattern is generated by the lighting control signal generation unit 203A, and transmitted from the signal transmission / reception unit 202 to each lighting fixture 21. .
[0158]
In each of the lighting fixtures 21 of each lighting subsystem 2B, when the signal transmission / reception unit 211 receives a lighting control signal including its own lighting fixture address from the lighting control controller 20B, the control contents included in the lighting control signal ( The control unit 210 controls the lighting device 212 according to the control operation pattern), so that the lamp load LD is dimmed (S53). At this time, the load power consumption value of each lighting fixture 21 is further reduced by 10% (see FIG. 14D).
[0159]
As described above, according to the fourth embodiment, when each lighting fixture 21 in the lighting subsystem 2B is classified by priority, each lighting fixture 21 is classified by priority based on the installation location information of each lighting fixture 21. Therefore, by preferentially performing power control from the lighting fixture 21 installed in a common place that does not affect work, it is possible to suppress a change in the visual environment and maintain a favorable work environment. Also, by making a difference in the amount of power reduction between the common place and the workplace (office room), efficient power reduction control can be performed while suppressing a change in the visual environment, as compared with a case where no difference is made.

May be. Alternatively, the above processing may be executed more regularly.
[0170]
The lighting control controller 20C includes a building network interface 201, a signal transmission / reception unit 202, and a power target value management unit 204 in the same manner as the lighting control controller 20B of the fourth embodiment, and differs from the lighting control controller 20B.

More specifically, in the case of the first power reduction instruction signal (power reduction level 1 in FIG. 19), the data table is used to provide the lighting fixture 21B having the current load power consumption value of 90% or more. On the other hand, an individual target value smaller by, for example, 30% is obtained, and a control operation pattern for operating with the individual target value is created. On the other hand, a control operation pattern for operating the lighting fixture 22 at the full lighting level is created.
[0175]
In the case where the second power reduction instruction signal (power reduction level 2) or the target is not achieved, a uniform predetermined rate (for example, 10% from the current load power consumption value) is given to each lighting fixture 21B of the lighting subsystem 2C. 3.) A small individual target value is determined, and a control operation pattern for operating with this individual target value is created. On the other hand, a control operation pattern for operating the lighting fixture 22 at the full lighting level is created.
[0176]
If the third power reduction instruction signal (power reduction level 3) or the target is not achieved, a uniform predetermined rate (for example, 10% from the current load power consumption value) is given to each lighting fixture 21B of the lighting subsystem 2C. 3.) A small individual target value is determined, and a control operation pattern for operating with this individual target value is created. On the other hand, a control operation pattern for operating the lighting fixture 22 at the normal lighting level is created.
[0177]
The lighting control signal generation unit 203B generates a lighting control signal that includes the lighting fixture addresses of the lighting fixtures 21B and 22 and matches the control operation pattern.
[0178]
Next, the operation of the management system according to the fifth embodiment will be described. When it is determined in the integrated monitoring device 1A that a power reduction request is issued through the same procedure as in the second embodiment, a power reduction instruction signal is generated and transmitted to each subsystem via the building network interface 11. Is done. Here, for example, it is assumed that a power reduction instruction signal of the power reduction level 1 is generated and transmitted from the integrated monitoring device 1A to each lighting subsystem 2C.
[0179]
In the lighting control controller 20C of each lighting subsystem 2C, as shown in FIG. 19, when the building network interface 201 receives the power reduction instruction signal of the power reduction level 1 from the comprehensive monitoring device 1A (S61), the power is reduced. The mode shifts to the power reduction control mode corresponding to level 1. Then, a subsystem target value for the power reduction level 1 is set by the power target value management unit 204, and subsequently, the control determining unit 205C reads the lighting fixture addresses of the lighting fixtures 21B and 22 and the lighting fixture addresses from the storage unit 206A. The type information is read, a lighting level response request is issued, and transmitted to each of the lighting fixtures 21B and 22 via the signal transmitting / receiving unit 202 and the wireless signal transmitting / receiving unit 207.
[0180]
In each of the lighting fixtures 21B and 22 of each lighting subsystem 2C, when a lighting level response request is received from the lighting control controller 20C via the signal transmission / reception unit 211 and the wireless signal transmission / reception unit 221, a load power consumption value and a lighting fixture are received. The address is transmitted to the lighting control controller 20C via the signal transmitting / receiving unit 211 and the wireless signal transmitting / receiving unit 221.
[0181]
In the lighting control controller 20C of each lighting subsystem 2C, when the load power consumption value and the lighting fixture address are acquired from each of the lighting fixtures 21B and 22 via the signal transmitting and receiving unit 211 and the wireless signal transmitting and receiving unit 221, the arithmetic processing unit 200C As a result, a data table is created in which the type of the lighting equipment and the load power consumption value are associated with the lighting equipment address. Thereafter, the control determination unit 205C obtains, based on the data table, an individual target value that is 30% smaller for the lighting fixture 21B having the current load power consumption value of 90% or more, and operates with the individual target value. A control operation pattern for operating the lighting fixture 22 at the full lighting level is generated. Thereafter, the lighting control signal generation unit 203B generates a lighting control signal that includes the lighting fixture address of the lighting fixture 21B whose current load power consumption value is 90% or more and matches the control operation pattern of 30% dimming. The data is transmitted from the transmission / reception unit 202 to each lighting fixture 21B. The lighting control signal generation unit 203B generates a lighting control signal that includes the lighting fixture address of the lighting fixture 22 and matches the control operation pattern of full lighting, and transmits the lighting control signal from the wireless signal transmitting and receiving unit 207 to each lighting fixture 22.

The control units 210B and 220 control the lighting devices 212B and 222 according to the control content (control operation pattern) included in the control signal, so that the lamp loads LD1 and LD2 are dimmed (S62). At this time, the load power consumption value of the lighting fixture 21B whose current load power consumption value is 90% or more is reduced by 30%, and each lighting fixture 22 is fully lit.
[0183]
In the lighting control controller 20C of each lighting subsystem 2C, the arithmetic processing unit 200C calculates the subsystem power consumption value from the latest load power consumption value, and determines whether or not it is equal to or less than the subsystem target value. (S63).
[0184]
If the subsystem power consumption value is equal to or smaller than the subsystem target value, the arithmetic processing unit 200C determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1A. After that, when a power reduction release signal is transmitted from the integrated monitoring device 1A, the lighting fixtures 21B and 22 operate with power consumption preset for normal operation according to the power reduction release signal.
[0185]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200C determines that the target has not been achieved (S64) or switches to the power reduction level 2 (S65), step S66 is performed. To the power reduction control mode corresponding to the power reduction level 2. Then, a subsystem target value for the power reduction level 2 is set, and an individual target value smaller by 10% is obtained for each lighting fixture 21B of the illumination subsystem 2C, and a control operation for operating with this individual target value is performed. While the pattern is created, a control operation pattern for operating the lighting fixture 22 at the full lighting level is created. If the power reduction instruction signal generated before step S61 is power reduction level 2, a subsystem target value for power reduction level 2 is set, and then a data table is created. A control operation pattern is created on the basis of this, and an individual target value smaller by 40% is obtained for the lighting fixture 21B having a current load power consumption value of 90% or more, and 10% for the other lighting fixtures 21B. In this case, a control operation pattern for operating at the full lighting level is created for the lighting fixture 22 while an individual target value that is smaller by% is obtained and a control operation pattern for operating at these individual target values is created. You may.
[0186]
Subsequently, a lighting control signal including a lighting fixture address of each of the lighting fixtures 21B and 22 of the lighting subsystem 2C and matching the control operation pattern is generated by the lighting control signal generation unit 203B, and transmitted from the signal transmission / reception unit 202 and the wireless signal transmission / reception unit 207. It is transmitted to each of the lighting fixtures 21B and 22.
[0187]
In each of the lighting fixtures 21B and 22 of each lighting subsystem 2C, when a lighting control signal including its own lighting fixture address from the lighting control controller 20C is received by the signal transmission / reception unit 211 and the wireless signal transmission / reception unit 221, the lighting is performed. The control units 210B and 220 control the lighting devices 212B and 222 according to the control content (control operation pattern) included in the control signal, so that the lamp loads LD1 and LD2 are dimmed (S66). At this time, the load power consumption value of the lighting fixture 21B whose load power consumption value is 90% or more is reduced by 40%, the load power consumption value of the other lighting fixtures 21B is reduced by 10%, and each lighting fixture 22 is reduced. Full lighting. The operation may be such that the load power consumption value of each lighting fixture 21B has the same constant dimming rate.
[0188]
In the lighting control controller 20C of each lighting subsystem 2C, the arithmetic processing unit 200C calculates the subsystem power consumption value from the latest load power consumption value, and determines whether the subsystem power consumption value is equal to or less than the subsystem target value for the power reduction level 2. Is determined (S67).
[0189]
If the subsystem power consumption value is equal to or smaller than the subsystem target value, the arithmetic processing unit 200C determines that the target has been achieved, and the current operation state of the management system is maintained. At this time, the subsystem power consumption value is transmitted to the integrated monitoring device 1A. After that, when a power reduction release signal is transmitted from the integrated monitoring device 1A, the lighting fixtures 21B and 22 operate with power consumption preset for normal operation according to the power reduction release signal.
[0190]
On the other hand, if the subsystem power consumption value exceeds the subsystem target value and the arithmetic processing unit 200C determines that the target has not been achieved (S68) or switches to the power reduction level 3 (S69), the process proceeds to step S70. To the power reduction control mode corresponding to the power reduction level 3. Then, a subsystem target value for the power reduction level 3 is set, and an individual target value smaller by 10% is obtained for each lighting fixture 21B of the illumination subsystem 2C, and a control operation for operating with this individual target value is performed. While the pattern is created, a control operation pattern for operating the lighting fixture 22 at the normal lighting level is created. If the power reduction instruction signal generated before step S61 is power reduction level 3, a subsystem target value for power reduction level 3 is set, a data table is created, and this data table is created. A control operation pattern is created based on the above, and an individual target value smaller by 50% is obtained for the lighting fixture 21B having the current load power consumption value of 90% or more, and 20% for the other lighting fixtures 21B. A control operation pattern for operating at the normal lighting level is created for the lighting fixture 22 while an individual target value that is smaller by% is obtained and a control operation pattern for operating at the individual target value is created. You may.
[0191]
Subsequently, a lighting control signal including a lighting fixture address of each of the lighting fixtures 21B and 22 of the lighting subsystem 2C and matching the control operation pattern is generated by the lighting control signal generation unit 203B. It is transmitted to each of the lighting fixtures 21B and 22.
[0192]
In each of the lighting fixtures 21B and 22 of each lighting subsystem 2C, when a lighting control signal including its own lighting fixture address from the lighting control controller 20C is received by the signal transmission / reception unit 211 and the wireless signal transmission / reception unit 221, the lighting is performed. The controller 210B, 220 controls the lighting devices 212B, 222 according to the control content (control operation pattern) included in the control signal, so that the lamp loads LD1, LD2 are dimmed (S70). At this time, the load power consumption value of the lighting fixture 21B whose load power consumption value is 90% or more is reduced by 50%, the load power consumption value of the other lighting fixtures 21B is reduced by 20%, and each lighting fixture 22 is reduced. Normal lighting. The operation may be such that the load power consumption value of each lighting fixture 21B has the same constant dimming rate.
[0193]
As described above, according to the fifth embodiment, when the lighting fixtures 21B and 22 in the lighting subsystem 2C are sorted by priority, the lighting fixtures are sorted by priority based on the type information of the lighting fixtures. In addition, efficient power reduction control can be performed while suppressing changes in the visual environment. In addition, since the decrease in the illuminance of the lighting fixture 21B can be compensated for by the increase in the illuminance of the lighting fixture 22, it is possible to reduce the total lighting power consumption and to suppress the deterioration of the lighting visual environment on the desk.

And are shared between each PC. The schedule information is also transmitted to the building equipment network via the gateway 6, so that each subsystem can acquire the above information.
[0198]
Next, a schematic operation of the management system according to the sixth embodiment will be described. The lighting subsystem 2D acquires schedule information (see FIG. 21) of the groupware communicated within the OA network system 7 via the wiring L1 (S71 in FIG. 23).
[0199]
The arithmetic processing unit of the illumination control controller in the illumination subsystem 2D performs arithmetic processing of the schedule information to extract the occupancy status of the office floor, and to the building management database in the integrated monitoring device 1B, the floor of the floor. An information request is transmitted to obtain floor information including an indoor layout map of a floor on which the lighting control controller is installed. Subsequently, the arithmetic processing unit of the lighting control controller obtains the lighting fixture address stored in the storage unit, the indoor location map of the lighting fixture address and the lighting fixture installation location, the layout contents (such as department information), and the department. Based on the schedule information, a data table as shown in FIG. 22 is created and transmitted to the control determining unit.
[0200]
When receiving the data table, the control determining unit rearranges the data according to the schedule information, creates a control operation pattern for turning off the lighting fixtures installed in the department that is absent in a meeting or the like, and creates a control operation pattern in the arithmetic processing unit. Output.
[0201]
The arithmetic processing unit outputs an illumination control signal generation instruction matching the control operation pattern to the illumination control signal generation unit.
[0202]
The lighting control signal generating unit generates a lighting control signal including a lighting fixture address installed in the absent department and a content for turning off the lighting fixture, and outputs each lighting in the lighting subsystem 2D via the signal transmitting / receiving unit. The data is transmitted to the device (S73, S77).
[0203]
The lighting equipment receives the lighting control signal, performs signal processing in the control unit, and, when the lighting equipment address included in the lighting control signal matches its own lighting equipment address, according to the content included in the lighting control signal. Control the lighting device.
[0204]
As described above, the power reduction control is performed using the personal information working at the installation location of the lighting fixture. The data table is updated every time the schedule information acquired from the OA network system 7 is updated, and the lighting control is automatically performed according to the updated data.
[0205]
The power reduction control as described above is executed stepwise according to the monitoring of the power consumption of the lighting subsystem 2D by the integrated monitoring device 1B, and details thereof are as follows.
[0206]
The comprehensive monitoring device 1B monitors the power consumption of the lighting subsystem 2D. The lighting fixture in the lighting subsystem 2D receives a lighting control signal transmitted from the lighting control controller, and transmits a signal transmitting / receiving information signal of the lighting fixture, a signal processing of the lighting control signal, operating state information of the lighting fixture. A control unit that generates a signal and issues a lamp power control instruction to the lighting device, a lighting device that performs lamp power control of a lamp load, and a lamp lighting level detection circuit that detects a lighting level of the lamp; Connected to the lighting control controller via a wire.
[0207]
Each lighting fixture in the lighting subsystem 2D first detects the current lamp lighting level with a lamp lighting level detection circuit in the lighting fixture and measures the detected value in the lighting fixture in order to measure its own power consumption. To the control unit. The control unit calculates a load power consumption value based on the rated lamp power consumption value of the lighting fixture and the detected value (lamp lighting level). Further, the load power consumption value is transmitted to the lighting control controller via the signal transmitting / receiving unit.
[0208]
When the lighting control controller receives the load power consumption value transmitted from each lighting fixture connected thereto, the arithmetic processing unit adds each load power consumption value to obtain a subsystem power consumption value, and the building network The data is transmitted to the integrated monitoring device 1B via the interface.
[0209]
The integrated monitoring device 1B calculates a system power consumption value by adding the subsystem power consumption values received from the lighting subsystems 7. The system power consumption value is transmitted to a power consumption monitoring unit in the integrated monitoring device, and is compared with a preset power consumption specified value.
[0210]
When the system power consumption value exceeds the specified power consumption value, the power consumption monitoring unit in the integrated monitoring device 1B issues a power reduction request to the control unit in the integrated monitoring device 1B. The control unit performs signal processing upon receiving the power reduction request, first generates a power reduction level 1 power reduction instruction signal, and transmits the generated power reduction instruction signal to the lighting subsystem via the building network interface.
[0211]
Further, if the power consumption monitoring unit monitors the power consumption value of the subsystem, if the power consumption is required to be further reduced, the control unit generates a power reduction level 2 power reduction instruction signal. , Send to subsystem.
[0212]
As described above, a power reduction instruction signal is generated in stages according to the monitoring status of the power consumption monitoring unit in the integrated monitoring device 1B and transmitted to the subsystem.
[0213]
When the lighting controller receives the power reduction instruction signal (power reduction level 1) transmitted from the integrated monitoring device 1B, the process proceeds to the first step (power reduction level 1) of the power reduction control. Then, the power target value management unit sets a power consumption target value (subsystem target value) of the lighting fixture. At the same time, the lighting control controller transmits a request for personal information of a floor occupant to the security system, and obtains personal information of a person occupying the place where the self is installed.
[0214]
The arithmetic processing unit of the lighting control controller adds the personal name and the age data of the personal information to the data table based on the schedule information that has already been created, and updates the data table (FIG. 21) to determine the control. Send to the department.
[0215]
Upon receiving the updated data table, the control determining unit rearranges the contents of the data table in the order of schedule and age. It is generally known that the work of the elderly requires a lighting environment of 500 [lx] or more, and the control judgment unit determines that lighting equipment near the floor where there are occupants of 50 years or older has the lowest rank. And a control operation pattern for achieving a reduction in the subsystem target value while suppressing a decrease in illuminance in the vicinity of the presence of the elderly is calculated. It should be noted that the lighting equipment in a place that is already absent is subjected to the lighting control based on the schedule information in the normal state, and is automatically turned off.
[0216]
In the first step of the power reduction, the control determination unit extracts the lighting device having the highest priority as the object of the power reduction control, performs lamp power control to lower the lighting level of the lighting device by, for example, 30%, and performs the priority control. For the lowest-order lighting fixture, a control operation pattern in which lamp power control is not performed is calculated and output to the arithmetic processing unit. The arithmetic processing unit outputs an illumination control signal generation instruction based on the control operation pattern from the control determination unit to the illumination control signal generation unit, and the illumination control signal generated by the illumination control signal generation unit is transmitted to the illumination control controller. Sent to the connected lighting fixture. The lighting device receives the lighting control signal, and the lighting device having the lighting device address corresponding to the signal content performs lamp power control for reducing the lighting level by 30%.
[0219]
After the power reduction control in the first step, if the target is not achieved or a power reduction instruction signal (power reduction level 2) is received from the integrated monitoring device 1B, the process proceeds to the second step of power reduction. The control judging unit further lowers the lighting level by, for example, 20% from the current lighting level to the lighting equipment one rank higher from the first priority to the lighting equipment from the lowest priority, and lights the lighting equipment with the lowest priority. A control operation pattern for lowering the level by 5% is created, an illumination control signal generation unit generates an illumination control signal that matches the control operation pattern, and performs lamp power control of the luminaire.
[0218]
In the case of shifting to the third step of power reduction (power reduction level 3), the lighting control controller determines that the urgency of power reduction is high, and regardless of the priority of the lighting apparatus previously given, The lighting control for lowering the lighting level by a uniform rate is performed for the lighting fixtures.
[0219]

The reduction in illuminance can be suppressed to a certain extent, and power reduction control of the illumination load can be performed while maintaining the visual environment.
[0220]
In addition, it is possible to perform power reduction control of lighting equipment in accordance with the schedule information of the groupware operating in the OA network system 7, and to automatically turn off the lighting equipment in a place where no person is present, thereby controlling the lighting equipment in a normal state. Can also perform power reduction control.

[0223]
Next, the operation of the management system according to the seventh embodiment will be described. When the lighting control controller receives the power reduction instruction signal (power reduction level 1) transmitted from the comprehensive monitoring device, the process proceeds to the first step of the power reduction control. Then, the power target value management unit sets a power consumption target value (subsystem target value) of the lighting fixture. In addition, the lighting control controller obtains the individual's presence status from the OA network system and the PC operation status information of the occupant, and also obtains the corresponding floor information from the building management database in the comprehensive monitoring device. get.
[0224]
Subsequently, the arithmetic processing unit of the lighting control controller acquires the lighting equipment address stored in the storage unit, and arranges the lighting equipment address and the indoor location of the installation location of the lighting equipment, the layout contents (department information, etc.), Based on the seat information and the personal computer operation information, a data table as shown in FIG. 24 is created and transmitted to the control determining unit.
[0225]
In general, it is known that the sensitivity of a worker to changes in the lighting environment is reduced when a personal computer is used. The first priority is given to nearby lighting fixtures.
[0226]
In the first step of power reduction, the control determination unit extracts a lighting device having the highest priority as an object of power reduction control, and performs control for performing lamp power control to lower the lighting level of the lighting device by, for example, 30%. An operation pattern is created and output to the arithmetic processing unit. The arithmetic processing unit outputs a lighting control signal generation instruction matching the control operation pattern to the lighting control signal generation unit, and transmits the lighting control signal generated by the lighting control signal generation unit to a lighting fixture connected to the lighting control controller. Is done. The lighting device receives the lighting control signal and performs lamp power control such that the lighting device having the lighting device address that matches the signal content lowers the lighting level by 30%.
[0227]
After the power reduction control in the first step, if the target is not reached or a power reduction instruction signal (power reduction level 2) is received from the comprehensive monitoring device, the process proceeds to the second step of power reduction. The control determination unit lowers the lighting level of the lighting device of the first priority near the floor where the personal computer is used by, for example, 20% lower than the current lighting level, and has a lower priority than the first priority. For the lighting equipment, a control operation pattern for lowering the lighting level by 10% is created, a lighting control signal generation unit generates a lighting control signal that matches the control operation pattern, and performs lamp power control of the lighting equipment.
[0228]
In the case of shifting to the third step of power reduction (power reduction level 3), the lighting control controller determines that the urgency of power reduction is high, and regardless of the priority of the lighting apparatus previously given, The lighting control for lowering the lighting level by a uniform rate is performed for the lighting fixtures.
[0229]
According to the seventh embodiment, the power reduction control is preferentially performed from the lighting fixtures near the personal computer worker whose sensitivity to the change in illuminance is reduced. Therefore, the power reduction control is performed while suppressing the change in the visual environment felt by the worker. It can be carried out.
[0230]
【The invention's effect】
As is apparent from the above description, the invention according to claim 1 provides a subsystem including a load device and a controller that controls the load device, and a power consumption monitor that monitors power consumption by the load device in the subsystem. And a general monitoring device having means for issuing a power reduction instruction to a controller in the subsystem when it is necessary to reduce the power consumption monitored by the power consumption monitoring means. A load control system including at least one of the subsystems included in the system, wherein the controller, upon receiving a power reduction instruction from the general monitoring device, supplies a current load to a load device in the subsystem to which the controller belongs. It is necessary to obtain a load output level lower than the output level and operate at this load output level. Since the general monitoring device does not need to perform specific control of the load device only by giving the power reduction instruction, the load of the arithmetic processing of the general monitoring device can be reduced. It can be simple and cheap. This makes it possible to provide a load control system that does not require a high-cost integrated monitoring device without increasing the load on the integrated monitoring device even when the system scale increases. For example, a subsystem is provided with a plurality of load devices, a plurality of subsystems is provided, or a plurality of types of subsystems are provided, thereby increasing the system scale. Even if the control is performed to obtain a load output level lower than the current load output level and operate at this load output level, the control is performed mainly by the controller, not by the general monitoring device. This enables efficient power reduction control of load devices without increasing the burden on the integrated monitoring device, and reduces the psychological adverse effects due to changes in the lighting environment when lighting devices are provided as load devices. Control is also possible.

According to a fourth aspect of the present invention, in the load control system according to the third aspect, the operation state information acquisition means acquires a current load output level of a load device including the self as the operation state information, and the controller Of the load devices classified by priority based on the operation state information from each of the load devices, at least the load devices classified into the priority having the highest load output level are lower than the current load output level. Since the load output level is obtained and control is performed so as to operate at this load output level, when the load device is, for example, a lighting device, efficient power reduction control can be performed while suppressing a decrease in overall illuminance.
[0234]
According to a fifth aspect of the present invention, in the load control system according to the third aspect, the load device is a lighting device, and the operation state information acquisition unit is connected to a load device including the same in a subsystem to which the load device belongs. The controller obtains the cumulative lighting time from the last as the operating state information, and the controller determines that the cumulative lighting time is the shortest at least among the load devices classified by priority based on the operating state information from each of the load devices. For lighting fixtures classified by priority, control is performed so that a load output level lower than the current load output level is obtained and operation is performed at this load output level, so efficient power reduction while suppressing overall illuminance reduction Control becomes possible.
[0235]
According to a sixth aspect of the present invention, in the load control system according to the second aspect, when the controller classifies each load device in the subsystem to which the controller belongs by priority, the controller uses the installation location information of each load device. Since each of the load devices is classified according to priority, when the load device is, for example, a lighting device, it is possible to suppress a change in the visual environment and maintain a favorable working environment.
[0236]
According to a seventh aspect of the present invention, in the load control system according to the second aspect, when the controller classifies each load device in the subsystem to which the controller belongs by priority, based on the type information of each load device. Since the load devices are classified according to priority, when the load devices are, for example, lighting devices, efficient power reduction control can be performed while suppressing a change in the visual environment.
