The lighting device 10 is preferably a lighting device using a light emitting device such as an LED including a function of adjusting the brightness according to the magnitude of the driving power input, and may be an existing lighting device such as a fluorescent lamp or an incandescent lamp. . Hereinafter, it demonstrates using LED.

The lighting device 10 such as an LED may adjust brightness of illumination by using on / off duty of input driving power (particularly, voltage).

The lighting target area is divided and managed into a plurality of lighting monitoring areas (monitoring areas), and a plurality of lighting devices are installed for each monitoring area, and the on / off and brightness of the lighting devices 10 are simultaneously controlled by each monitoring area. It is composed.

The control controller 20 preferably includes an SMPS (not shown) capable of arbitrarily controlling the on / off of electric power so as to arbitrarily adjust the brightness of the lighting device 10. The driving power is controlled according to the power control signal) and supplied to the lighting device 10.

The control controller 20 is preferably arranged in each of the lighting device 10 to individually control the supply of drive power.

When the luminance / illuminance sensor 31 divides an illumination target area illuminated by each of the plurality of lighting devices 10 into a plurality of monitoring areas, a plurality of brightness / illuminance sensors 31 may be disposed for each monitoring area, and the illumination target area One may be installed in a representative position of the. The luminance / illuminance sensor 31 may detect the input light and continuously output the measured value detecting the luminance / illumination of the surroundings in the form of an analog signal. Of course, it is also possible to output the digital information every predetermined time (for example, 0.1 second, 1 second, etc.).

When the plurality of luminance / illuminance sensors 31 are directly connected and receive the measured values outputted from the program switches 30, the program switch 30 digitally identifies the identification information and the measured values for displaying the luminance / illuminance sensors 31. Information is converted and transmitted to the central control server 40 through the connected communication network. In addition, in the program switch 30, a plurality of control controllers 20 are directly connected, and identification information of each control controller 20 is provided. By maintaining it, it is possible to transmit the designated command to the specified control controller 20 according to the identification information included in the input power control command.

That is, when the program switch 30 receives the measurement values of the luminance and illuminance for each monitoring region from the plurality of luminance / illuminance sensors 31, the program switch 30 is inputted every predetermined time together with the identification information indicating the monitoring region. Outputs through the communication network, and analyzes the lighting control command output from the central control server 40 through the communication network to identify identification information for identifying any control controller among the plurality of control controllers and a power control signal for the control controller to be controlled. It reads out and outputs a power control signal to the identified control controller 20.

The power control signal may be a signal indicating a driving power supply duty of the control controller 20.

Here, in the manner in which the plurality of control controllers 20 are connected to the program switch 30, the control controller 20 of the lighting device 10 that is being installed and used in the existing can be used as it is without changing the wiring separately. As such, an Ethernet connection method as shown in FIG. 1 or a method in which each control controller 20 is directly connected one by one may be variously applied.

The central control server 40 is connected to and communicated with the program switch 30 through a communication network, and identification information for identifying the luminance / illuminance sensor 31 from the program switch 30 and measured luminance and illuminance (measured value). ) And a power control signal for changing the brightness of the lighting device 10 installed in the monitoring area when the control value for each monitoring area is greater than or less than the preset control brightness for the monitoring area of the received measured value and the measured position.

The human body detection result of detecting the presence of a user can be output.

When the presence of the human body is detected by the motion / infrared sensor 32 and the human body detection result is output, the program switch 30 immediately outputs the identification information of the monitoring area and the human body detection result to the central control server 40 through a communication network. The central control server 40 controls to turn on / off or change the brightness of the lighting device 10 in the surveillance region in which the human body detection result is output.

Next, an automatic power saving method by the automatic power saving system according to an embodiment of the present invention configured as described above will be described.

2 is a flowchart for explaining a central control automatic power saving method.

First, the automatic power saving system according to the present invention is driven, and the control brightness of the area to be illuminated is set in the central control server 40 (S10). Then, the central control server 40 generates a lighting control command for turning on the lighting device 10 disposed in all the monitoring area of the lighting target area, and outputs the generated lighting control command to the program switch 30 (S20). ).

The program switch 30 outputs a power control signal to the control controller 20 of all the lighting devices 10 according to the input lighting control command (S30). The control controller 20 drives the lighting device 10 in response to the power control signal.

When the lighting device 10 is driven, the luminance / illumination sensor 31 measures the luminance and illuminance of the surroundings, and outputs the measured value to the program switch 30. The program switch 30 receives the measured value and identifies the position of the luminance / illuminance sensor 31 that outputs the measured value (identification of the surveillance area including the position where the luminance / illumination sensor performs measurement). Information) and the outputted measurement value to the central control server 40.

When the luminance control value is input (S40), the central control server 40 generates a lighting control command for each monitoring area and outputs it to the program switch 30 (S50), and the program switch 30 controls the central control server ( Analyzing the lighting control command output from the 40, and outputs a power control signal to the control controller 20 of the designated lighting device 10 to control the brightness of the illumination for each monitoring area (S60).

FIG. 3 is a flowchart for explaining an example of a method of controlling the illumination target area as a whole without controlling illumination for each monitoring area as in FIG. 2. First, a measurement value is input from each luminance / illuminance sensor 31 for each of a plurality of monitoring regions in which brightness of illumination is monitored (S511).

When a plurality of measured values are input, the maximum value and the minimum value are deleted (S512), and the average value is calculated using the remaining measured values (S513). The average value calculated at this time is computed without considering each monitoring area | region with respect to the whole illumination target area | region, and becomes a global average value.

Meanwhile, when the global average value is calculated, the control brightness and the magnitude inputted in step S10 of FIG. 2 are compared (S514). And if the global average value is determined to be brighter than the control brightness, generate a power control signal for reducing the brightness for all the lighting devices 10, and if the global average value is determined to be darker than the control brightness, for all the lighting devices 10 Generate a power control signal to increase The generated power control signal is transmitted to each control controller 20 through the program switch 30 as a lighting control command (S515).

According to this configuration, the brightness can be controlled by the average value by removing the maximum and minimum values that can be considered to be caused by errors in luminance / illuminance measurement or temporary disturbances or temporary changes in the surrounding environment, thereby enabling efficient brightness control. have.

That is, for example, when a person wearing bright clothes passes through the area to be illuminated, or when temporary solar reflection light is incident from an object passing through the outside, the brightness of the entire area to be illuminated is changed by such a situation. The error can be prevented.

4 is a flowchart for explaining an example of the control method in the case of controlling illumination for each monitoring area. Control by surveillance area as shown in FIG. 4 may be performed separately in each of all surveillance areas, whereby brightness is individually controlled for each surveillance area.

First, when a measurement value for luminance / illuminance is periodically input for each monitoring area in step S40 in the flowchart of FIG. 1, temporarily store the measured value input for an arbitrary time interval (S521) and temporarily store the measurement. The maximum and minimum values are deleted from the values (S522), and the average value is calculated using the remaining measured values (S523). The average value thus calculated is an average value for the luminance / illuminance change for a predetermined time in any monitoring region, and becomes an average value for each region.

On the other hand, when the average value for each area is calculated, the control brightness set in step S10 of FIG. 2 is compared with the average value for the monitoring area (S524). By this comparison, if it is determined that the average value for each area is brighter than the control brightness for each area, a power control signal is generated to lower the driving power to the lighting device 10 in the monitoring area to lower the brightness, and the average value for each area is for each area. If determined to be darker than the control brightness, a power control signal is generated to brighten the illumination of the surveillance area. The generated power control signal is transmitted to the program switch 30 as a lighting control command including identification information of the corresponding monitoring area, and the program switch 30 transmits the power control signal included in the lighting control command to each control controller 20. And outputs the control to the lighting device 10 (S525).

According to this control, it is possible to suppress unnecessary fluctuations in illumination due to temporary fluctuations in luminance / illuminance for each monitoring region.

According to the central control automatic power saving system according to the present invention having the above-described configuration, it is possible to individually control each lighting device 10 by using the program switch 30, the area to be illuminated It is possible to control the brightness of the light by dividing.

In addition, even when a person wearing bright clothes passes through the surveillance area, or when temporary solar reflection light from an object passing by is incident, even if the luminance or illuminance being monitored momentarily rises, the entire area to be illuminated is affected by this effect. It is possible to prevent the error that the brightness of the light to change.

In addition, since the illumination of each surveillance area constituting the illumination target area can be individually controlled remotely, centralized management can be easily performed.
