DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting system for illuminating a lighting fixture by controlling the illuminance of a lighting fixture based on image information obtained by an image pickup means, and a method of setting an ID of the lighting system.

[0002]

2. Description of the Related Art Hitherto, in order to realize energy saving, there has been proposed a lighting fixture in which a human detection sensor for detecting heat rays or the like is attached to, for example, a lighting fixture main body to control the light source of the lighting fixture itself to blink. Further, in a lighting system installed in an office or the like having many lighting fixtures, an external light illuminance sensor that is appropriately installed near a window or the like detects the intensity of external light incident from the window, and responds accordingly. In some cases, the light source of the lighting equipment is turned on or off or the brightness is controlled. In this case, a unique ID number is assigned to the lighting equipment, the lighting equipment is made to correspond to each of the appropriately divided lighting areas, pattern control is performed for each lighting area according to the intensity of external light, and the indoor lighting is appropriately adjusted. Maintaining brightness is also being done.

Instead of the human detection sensor and the ambient light illuminance sensor, an image pickup means for detecting at least one of color and brightness image information of an illumination space, and image information inputted from the image pickup means are processed to provide illumination. There is an illumination control system disclosed in Japanese Patent Application Laid-Open No. 7-45370, which includes a control unit for controlling a lighting state of an appliance and illuminates an illumination space.

As a lighting control system having the above-mentioned image pickup means, the present applicant has disclosed a television camera for outputting image information disclosed in, for example, Japanese Patent Application Laid-Open No. 10-162967 as shown in FIG. An illuminance measuring unit including an imaging unit such as 101, a storage unit 105 for storing image information, and a luminance / illuminance conversion unit for performing an illuminance calculation of an imaging area based on luminance information of the image information stored in the storage unit 105 104, an illumination control means 106 for generating and outputting a predetermined illumination control signal based on the output from the illuminance measuring means 104, and a lighting fixture for inputting the illumination control signal 106 and controlling the light source to illuminate a predetermined area In the lighting control device 100 having the mounting conditions 102, the mounting condition input means 10 for inputting the mounting conditions of the mounting height and the mounting angle of the imaging means 101.
7 and the luminance / illuminance conversion means calculates the distance to the measurement point in the imaging area by the imaging means based on the mounting condition information, and corrects the luminance information based on the calculation result to calculate the illuminance. I suggest something.

When the human detecting sensor and the external light illuminance sensor are replaced with the image pickup means 101 as described above, a plurality of lighting fixtures 102 can be controlled without providing a large number of illuminance sensors and the like, and the cost for installation and maintenance of the sensors is reduced. Can be reduced. Further, it is possible to perform fine control of the lighting environment based on the image information, and it is possible to easily cope with a case where the layout inside the lighting space is changed.

[0006]

In the illumination system having the above-mentioned prior art image pickup means, the luminaire 102 is used.
Are connected via a signal line 108 serving as a control line, and this signal line 108 is
, And is controlled via an illumination control unit 103 serving as a master unit having an image pickup means 101 connected to the camera. In addition, a television camera serving as the imaging unit 101 is installed on a wall surface like a general surveillance camera. For this reason, there is a problem that it takes time to adjust the installation state of the imaging unit so that the entire illumination space can be controlled.

[0007] By the way, in the case where the lighting equipment is given a unique ID number, and the lighting equipment is made to correspond to each appropriately divided lighting area, and the pattern control for each lighting area is performed,
It is often done using a dedicated setting device such as an infrared remote controller. However, in this case, when there are a large number of lighting fixtures, much time is required for the setting operation. As a countermeasure, it is conceivable to improve the lighting control unit by providing the lighting control unit with an automatic ID number assigning function. However, in this case, it is supposed that it is possible to cope with a change in the size of the illumination space and the like, and the operation for automatically assigning ID numbers becomes complicated.

In the lighting system of this embodiment, the lighting fixtures 1 are connected to each other by a control line 3 and transmit and receive control signals to and from the master unit 10 to control the light source. There are. Further, in the lighting system of the present embodiment, the master unit 10 is built in one of the plurality of lighting fixtures 1, 1,.... In the lighting system according to the embodiment,
Each of the plurality of lighting devices 1, 1... Is assigned a unique ID.
A number is given and the illumination space is divided into desired illumination areas (for example, B, C, D) to correspond to each other, and pattern control is performed for each illumination area. In the lighting system according to the embodiment, the master device 10
The pattern control may be performed by recognizing the presence of a person in the illumination area based on image information from the imaging unit.

More specifically, this lighting system is installed on a ceiling surface of an office or the like that requires many lighting fixtures 1 to appropriately illuminate the entire office as a lighting space and effectively achieve energy saving. It is something that can be done. As shown in the plan view of FIG. 1, among the plurality of lighting fixtures 1, 1... Having the same external shape, the lighting fixture 1 installed in the upper center of the lighting space becomes the master unit 10, and inside the master unit 10, A television camera serving as an imaging unit is provided. This television camera captures an image of a substantially circular area A which is the entire office as shown in FIG.

In this case, the lighting fixtures 1, 1... Are embedded and installed on the ceiling surface above the lighting space, and are connected to each other via a control line 3 which is a signal line. In addition, the lighting fixtures 1, 1... Are arranged such that the substantially horizontal mounting plane is such that each of the lighting fixtures 1 is attached to a fixture hanging down from the ceiling surface in addition to being embedded in the ceiling surface.
May be fixed, or may be configured via a frame-like mounting channel. This lighting fixture 1
Is a fluorescent lamp 11 of, for example, a straight tube type as a light source, a ballast 12 formed by a high-frequency lighting control circuit for lighting the fluorescent lamp 11, and a control unit 13 for controlling the ballast 12.
And a signal receiving unit 14 that receives a control signal from a master unit 10 described later, and a power supply unit 15 that receives an AC power supply AC, stabilizes the DC power, and supplies power to each unit inside the lighting fixture 1. .

The ballast 12 turns on and dims the fluorescent lamp 11, and is operated only by a control signal from the control unit 13. In this case, a master unit 10 described later is used.
From the control unit 13 via the control line 3 and the signal receiving unit 14
The dimming signal is input to the controller. The ballast 12 receives the signal from the signal receiving unit 14 and
Control. In this case, the signal from the signal receiving unit 14 is an oscillation command of the ballast 12 or a dimming control signal. The time is determined, and each ballast 12 of each lighting fixture 1 operates in the same manner as a master unit 10 described later.

The signal receiving section 14 receives a signal from a signal transmitting section 16 of the master unit 10 described later, that is, an oscillation command of the ballast 12 by a digital pulse signal or a dimming signal, and receives a signal from the control section 13 of the lighting fixture 1. It has the function of transmitting to

The master unit 10 includes, in addition to the fluorescent lamp 11, ballast 12, and control unit 13, a signal transmission unit 16 and an imaging unit 17 formed by a television camera having a solid-state imaging device corresponding to an imaging unit. An image control unit 18 that generates an illumination control signal by performing image processing by the imaging unit 17; and a power supply unit 15 that receives an AC power supply AC, stabilizes the DC power, and supplies power to each unit inside the base unit 10. ing.

The image control unit 18 detects the presence of a person by processing the image data of the area A, which is the imaging range obtained by the imaging unit 17. This image control unit 18
Simultaneously corrects the distortion of the image data obtained from the imaging unit 17, and outputs the presence state of the person to the control unit 13 of the master unit 10 as an illumination control signal based on a digital pulse signal. In this case, the image control unit 18 performs processing by subdividing the image data into fine areas in a matrix as shown in FIG. That is, the entire imaging area A is divided into one lighting fixture 1 in the lighting system as a minimum division unit a to perform image processing, and the presence of a person below and near each lighting fixture 1 is determined. I try to detect. Therefore, the control unit 13
As the information to be output to, the presence status of a person and the minimum division unit a where the person is present, that is, an ID number previously assigned to the lighting fixture 1 in the divided region described later is output as a lighting control signal. .

The control unit 13 of the master unit 10 includes an image control unit 18
From the signal output from the camera, the presence state of a person in the entire imaging area A is determined. When no person exists, the high-frequency output from the ballast 12 is stopped or the dimming lower limit state is set. To output a high-frequency signal and light it at the dimming upper limit. The control unit 13 is configured to output a high frequency for a certain period of time and turn on the fluorescent lamp 11 after turning on the fluorescent lamp 11 or turn on the dimming lower limit when the person changes from the presence state and the person no longer exists. That is,
The ballast 12 is controlled on the basis of the time set in the timing means inside the control unit 13. If there is a signal output from the image control unit 18 again during the time counting by the time counting means, the time counting state is returned to the initial state.

The control signal in the high-frequency output state or dimming state of the ballast 12 based on the signal output from the image control unit 18 is directed to the luminaires 1, 1. It is transmitted by a digital pulse signal or a dimming signal. Each of the lighting fixtures 1, 1,... Operates in the same manner as the master unit 10.
That is, the signal transmission unit 1 is provided only to the lighting device serving as the master device 10.
6, and transmits a slave unit control signal via the control unit 13 of the master unit 10 to each of the lighting fixtures 1, 1... The slave unit control signal indicates an oscillation command of the ballast 12 of the lighting fixture 1 by a digital pulse signal, or a dimming control signal of the ballast 12 such as a PWM signal or an AD signal. 3 is transmitted.

In this case, the control unit 13 of the master unit 10 assigns ID numbers as table data to a plurality of lighting devices 1, 1... Are separated from each other. Also, as shown in FIG. 4B, the illumination space has grouping information on divided areas obtained by dividing an illumination space into, for example, illumination areas B, C, and D. That is, as shown in the figure, each lighting fixture 1, 1... Also has pattern control information for dividing, for example, the entire lighting area into three lighting areas obtained by dividing the lighting area into three areas. Therefore, when there is no person for each minimum division unit a, the control unit 13 can turn off the lamp or set the light control lower limit state for each corresponding illumination area.

That is, when there is a signal output from the image control unit 18, the presence state of the person for each minimum division unit a and the ID numbers of the luminaires 1, 1...
The slave unit control signal is transmitted to the lighting fixture 1 having the same group ID number as the lighting fixtures 1, 1... Then, the corresponding lighting fixtures 1, 1 ...
Is to turn on the lamp or the upper limit of dimming when the ID number is applicable, turn off after turning on for a certain period of time, or
Turn on the dimming lower limit.

As described above, in the lighting system having the above configuration, the plurality of lighting fixtures 1, 1... Provided on the ceiling surface above the lighting space are arranged on a substantially horizontal mounting plane, and By the signal output from the image control unit 18 based on the image information of the illumination space acquired by the imaging unit 17 of the base unit 10 arranged at substantially the center of the plane, the high frequency output from the ballast 12 of each lighting fixture 1 is output. Stop, or set to the dimming lower limit state, output high frequency, and light at the dimming upper limit. At this time, the plurality of luminaires 1, 1... Disposed on the substantially horizontal mounting plane are connected to each other by the control line 3 and mutually with the master unit 10 disposed substantially at the center of the mounting plane. Illuminance control is performed by transmitting and receiving control signals, for example, human detection is possible over the entire area A with only one imaging unit 17, and a wide range of control can be performed with a simple configuration. If there is a person somewhere in the area A, all the lighting fixtures 1, 1... Can be controlled collectively.

At this time, a plurality of lighting fixtures 1, 1...
Is a master unit 10 arranged substantially at the center of the same mounting plane.
It is designed to transmit and receive a control signal to and from the lighting equipment to be controlled, and to control the illuminance, so that the imaging means (television camera) is not directly exposed at a conspicuous position above the lighting space, which is preferable from the viewpoint of beauty.

A plurality of illuminations each having a unique ID number corresponding to an illumination space for each illumination area divided as desired, which is provided on a substantially horizontal mounting plane such as a ceiling above the illumination space. By dividing the captured image based on the image information of one imaging unit 17 of the master device 10 arranged at substantially the center of the mounting plane of the lighting devices 1, 1,. Can be illuminated by performing pattern control of each individual control with a relatively small amount of information communication and a simple communication network, and further, for example, the illumination space for each of the three divided illumination areas B, C, and D ., Each of which has a unique ID number, recognizes the presence of a person in the lighting area, controls the pattern, and illuminates. Image information by the imaging unit 17 Usability becomes possible to control a large number of areas Zui good.

By the way, the unique ID of the lighting system
In the ID setting method for setting a number, the plurality of lighting devices 1, 1... Are sequentially turned on, and the arrangement position of the lighting device 1 is recognized based on image information of an imaging space based on the image information. The ID numbers of the respective lighting fixtures are sequentially set.

That is, in such a lighting system,
In general, an ID number is assigned to each of the plurality of lighting fixtures 1, 1,... For management and control, and the ID numbers are associated with the actual positions of the lighting fixtures 1 and their ID numbers. In this embodiment, the control unit recognizes the correspondence between the ID number and the position by a simple method. Specifically, FIG.
(A), (b), (c), and (d) are lighting fixtures 1 from before ID number assignment to completion of ID number assignment.
1 are shown, and an ID setting method of the lighting system according to the present embodiment will be sequentially described with reference to FIG.

FIG. 5A shows a temporary setting state of an initial ID number. That is, after installing the lighting fixture 1,
When the power is turned on, first, for example, a random number is generated in each lighting fixture 1 and the random number is returned to the base unit 10, and the master unit 10 issues a temporary ID number to the lighting unit 1 of the slave unit based on the order of the random numbers. It is assumed that the ID numbers are randomly assigned. Therefore, at this stage, master device 10 manages the ID number of each lighting fixture 1 but does not recognize the position of the fixture for each ID number. (By changing this assignment to the assignment state shown in FIG. 5D, the assignment of the ID number is completed.)

Next, the temporary ID randomly assigned
In order to turn on the lighting fixtures 1 in the order of the numbers, first, the lighting fixtures 1 to which the temporary ID number 1 is assigned are turned on as shown in FIG. At this time, the imaging unit 17 of the base unit 10 captures an image of the area A, which is the entire lighting area, and the area A is divided according to the number of the lighting fixtures 1, 1,.
As shown in the figure, the imaging area A is divided into 15 small areas a to o. Accordingly, as shown in FIG. 3C, the image from the imaging unit 17 shows a stepwise brightness for each region,
In this case, the area c is the brightest, and then b, d, g, h, i, which is an area adjacent to the c, is slightly brighter, and the other areas farther from the c are slightly brighter. In this way, the lighting fixture 1 installed in the brightest area c is recognized as the lighting fixture 1 to which the temporary ID number 1 is assigned, and the correspondence between the temporary ID number and the position of the lighting fixture 1 can be obtained. . That is, the ID number of the lighting fixture 1 corresponding to the area c in the ID number target setting diagram of FIG.
And the temporary ID number 1 is changed to the ID number (3).
Will be updated to After that, the above lighting fixture 1 which was lit
Is turned off, and the lighting fixture 1 assigned the next temporary ID number is turned on. By sequentially performing such processing, the update from the temporary ID number to the target ID number is performed in all the lighting fixtures 1, and the I corresponding to the arrangement of the lighting fixtures 1 is updated.
D number assignment is completed.

That is, first, a plurality of lighting fixtures 1, 1... Provided above a lighting space such as a ceiling are sequentially turned on, and then arranged on a substantially horizontal mounting plane and substantially at the center of the mounting plane. The arrangement position of the lighting fixture is recognized based on the image information of the lighting space acquired by the imaging means of the base unit 10 to be operated, and only after the plurality of lighting fixtures 1, 1. Automatically each unique I
The D numbers are set sequentially.

The method of assigning a temporary ID number is not limited to the method described above. For example, a plurality of lighting devices 1, 1,.
A method of giving an individual ID number from the manufacturing stage and returning the ID number in response to a request from the lighting equipment of the master unit 10, or lighting of the slave unit from the master unit 10 as shown in FIG. .. Can be connected by serial wiring, and various setting methods such as a method of sequentially assigning ID numbers in ascending order from the master device 10 are possible. Of course, the lighting devices are turned on one by one. In addition, it goes without saying that the lighting fixtures 1, 1... May be turned off sequentially from the temporary ID number 1 while all the lighting fixtures are turned on. In addition to the configuration in which the master unit is built in one of the plurality of lighting fixtures as described above, as shown in FIG.
May be provided. In this case, the main unit 10 can be formed in a shape as compared with the above-described master unit 10, and it is possible to easily install the unit in an irregular space that is relatively difficult to cope with, such as the case where the movable partition 4 is provided.

Therefore, according to the lighting system described above, the plurality of lighting fixtures 1, 1... Provided above the lighting space such as the ceiling are arranged on a substantially horizontal mounting plane, and substantially at the center of the mounting plane. Since the illuminance is controlled based on the image information of the illumination space acquired by the imaging unit of the master unit 10 disposed in the base unit, the installation of the master unit 10 having the imaging unit is facilitated.

A plurality of luminaires 1, 1... Arranged on a substantially horizontal mounting plane are connected by a control line 3 and are arranged at a substantially center of the mounting plane.
Since the illuminance is controlled by transmitting and receiving a control signal to and from each other, a wide range of control can be performed with a simple configuration. A plurality of luminaires 1, 1... Each connected by a control line 3 and disposed on a substantially horizontal mounting plane serve as a base unit 10 disposed substantially at the center of the same mounting plane. Since the illuminance is controlled by transmitting and receiving control signals with the equipment,

With the fixtures 1, 1,..., The pattern can be controlled and illuminated based on the image information from the master unit 10 arranged substantially at the center of the mounting plane.
It is possible to illuminate each individual control of 1 ... with a relatively small amount of information communication and pattern control with a simple communication network, and to provide it on a substantially horizontal mounting plane such as a ceiling above the lighting space. A plurality of lighting devices 1, 1... Each having a unique ID number corresponding to a lighting space of each lighting area divided as desired, and arranged at a substantially center of the mounting plane. Therefore, it is possible to recognize the presence of a person in the illumination area based on the image information and control the pattern to perform illumination.

In this case, in the method of setting the ID of the lighting system, first, a plurality of lighting fixtures provided above the lighting space such as a ceiling are sequentially turned on, and then arranged on a substantially horizontal mounting plane. The arrangement position of the lighting fixture is recognized based on the image information of the lighting space acquired by the imaging unit of the master unit arranged substantially at the center of the mounting plane, and a unique ID number is sequentially set for each lighting fixture. Therefore, the work of setting the ID number of the lighting fixture can be reduced and the workability is good.
