Description

[0001] SYSTEM AND METHOD FOR CONTROLLING ILLUMINATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination system, and more particularly, to an intelligent illumination control system and method that enable effective control of individual illumination according to a user's activity state in an illumination space provided with a plurality of illumination lamps.

In general, as the number of lights installed in a room increases, a plurality of switches for lighting and extinguishing each of the lights are embedded in the wall, or a switch for turning on or off all or a part of the switches is installed.

However, when a plurality of switches are installed, the user must be aware of the switches of the corresponding lamps, and if a batch switch is installed, the lamps can not be selected and turned on / off arbitrarily.

In recent years, there has been an increasing number of cases in which a control box capable of controlling a plurality of lights is installed for the convenience of the user. However, such a control box is also installed on the wall surface of each zone, and further, it is difficult to change the structure because it is formed in the form of a wire.

In order to solve these problems, an illumination system has been recently introduced, in which a wireless communication module is installed in each of a plurality of illumination lamps and a plurality of illumination lamps are controlled using wireless communication between illumination lamps.

1 is a schematic view showing the concept of a conventional illumination system using wireless communication. In FIG. 1, an example in which an illuminating lamp that has received a control command from the user terminal 20 transmits a control command to the adjacent illuminating lamp 10-2 using wireless communication (10-1).

In addition, in a large space with a large number of lights, such as a large-sized office, lighting is always turned on throughout the working hours so that the entire space can be illuminated. As a result, power wastage is frequently raised as a recent problem.

In order to solve these problems, there has been proposed a method in which a worker automatically detects when a user enters the office and performs lighting, and turns off the lights when entering the office. In this case, however, The problem is still there.

In addition, although a method of performing illumination only at the current position of the worker has been suggested, it is rather inefficient to turn on or off the individual illumination frequently according to the position change of the worker. It is difficult to identify the area.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lighting control system capable of effectively performing spatial illumination in accordance with worker activity or business activity in an illumination space provided with a plurality of lights, And a method thereof.

According to an aspect of the present invention, there is provided an illumination control system for controlling illumination in an illumination space including a plurality of divided illumination spaces, the illumination control system including an entrance detection unit, an entire illumination unit, And a position illumination unit, wherein the user position confirmation unit includes a motion detection unit and a communication terminal position detection unit.

The entrance sensing unit detects the entrance of the user into the illumination space and the advancement in the illumination space. The entire illumination unit illuminates the entire illuminating space with the first illuminance when the entrance of the user is detected. When the entrance of the user is detected, And the user position illuminator confirms the position of the user in the illumination space, and when the user's position is confirmed, the user illuminates the divided illumination space in which the user is located, . In addition, the motion sensing unit senses the movement of the user in the illumination space, and the communication terminal position sensing unit senses the position of the user's communication terminal in the illumination space.

According to this configuration, when the user enters the illumination space, the user performs weak illumination for the entire space and performs strong illumination only for the position of the identified user, thereby significantly reducing power consumption for the entire illumination space , It is possible to improve the identification of the user's surrounding area while preventing the inefficiency of frequently turning on or off the individual lights according to the user's position change. Particularly, it is possible to prevent the malfunction of the illumination system due to the error of the user's position by performing the detection of the position of the communication terminal of the user as well as the motion detection for checking the user's position.

At this time, the entire illumination unit can stop the illumination of the divided illumination space, which is set in advance, when the movement of the user is detected over a predetermined time in the divided illumination space in which the position of the user is confirmed. According to such a configuration, the power consumption can be further reduced in a space where there is little influence on the movement or activity of the user.

The predetermined divided illumination space may be a divided illumination space not adjacent to the identified divided illumination space, and may be a predetermined divided illumination space corresponding to the identified divided illumination space.

In addition, if the movement of the user is not detected in the divided illumination space in which the user is located, the user position confirmation unit can confirm the position of the user's communication terminal in the divided illumination space from the communication terminal position sensing unit. In addition, the user location illumination unit suspends the illumination in the divided illumination space when the position of the user's communication terminal is not confirmed, waits for a predetermined waiting time when the position of the user's communication terminal is confirmed, The illumination in the divided illumination space can be stopped. According to such a configuration, even if the user's position is once confirmed, when the user leaves the identified position, the lighting operation at the corresponding position can be stopped.

In addition, a compensation data input unit for inputting the illumination compensation position and the illumination adjustment input in the illumination space from the user's communication terminal, an illumination adjustment unit for adjusting the illumination illumination at the illumination compensation position according to the illumination adjustment input, And an illuminance setting unit for setting the illuminance adjustment value at the illuminance compensation position using the final illuminance adjustment input inputted from the illuminance adjustment unit. According to this configuration, the lighting manager can easily perform the correction of the illuminance sensor in the illumination space by using his / her communication terminal.

At this time, the compensation data input unit further receives the illuminance compensation position in the illumination space from the user's communication terminal and the illuminance adjustment information of the illuminance compensation position in which the illuminance adjustment value is preset, and the illuminance setting unit The illuminance adjustment value at the preset illuminance compensation position can be further set as the illuminance adjustment value at the illuminance compensation position for copying. According to such a configuration, it becomes possible to more easily perform the correction of the illuminance sensor for a plurality of illumination spaces in a similar illumination state.

Also, the user location confirmation unit may include a communication module, and the communication module may include at least one of an infrared communication module and a Bluetooth communication module.

In addition, the invention in which the system is implemented in the form of a method is also disclosed.

According to this configuration, when the user enters the illumination space, the user performs weak illumination for the entire space and performs strong illumination only for the position of the identified user, thereby significantly reducing power consumption for the entire illumination space , It is possible to improve the identification of the user's surrounding area while preventing the inefficiency of frequently turning on or off the individual lights according to the user's position change.

Particularly, it is possible to prevent the malfunction of the illumination system due to the error of the user's position by performing the detection of the position of the communication terminal of the user as well as the motion detection for checking the user's position.

In addition, the power consumption can be further reduced for a space with little influence on the user's movement or activity.

In addition, even if the user's position is once confirmed, when the user leaves the identified position, the lighting operation at that position can be stopped.

Further, the lighting manager can easily correct the illuminance sensor in the illumination space using his / her communication terminal.

Further, it becomes possible to more easily perform the correction of the illuminance sensor for a plurality of illumination spaces in a similar illumination state.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a schematic block diagram of a lighting control system in accordance with an embodiment of the present invention. 2, the illumination control system 100 for controlling illumination in an illumination space including a plurality of divided illumination spaces includes an entrance detection unit 110, an entire illumination unit 120, a user position confirmation unit 130, A position illumination unit 140, a compensation data input unit 150, an illumination control unit 160, and an illuminance setting unit 170. At this time, the user location confirmation unit 130 includes a motion detection unit 132 and a communication terminal position detection unit 134 again.

The entrance detection unit 110 detects entry of the user into the illumination space and advancement of the illumination space. For this purpose, the entrance detection unit 110 may be disposed at an entrance of an illumination space such as an office, and may detect entrance and exit of a user by using sensors such as a motion detection sensor and an entrance card detection sensor.

The entire illumination unit 120 illuminates the entire illuminating space in a first illuminance when a user's entry is detected and halts the entire illumination in the illuminated space when a user's advance is detected. In this case, the first illuminance is an illuminance set to be smaller than a preset effective illuminance for effective illumination of the illuminated space, for example, the illuminance of the effective illuminance may be 20%.

The user location confirmation unit 130 confirms the location of the user in the illumination space. For this purpose, the motion sensing unit 132 senses the movement of the user in the illumination space, and the communication terminal position sensing unit 134 senses the position of the user's communication terminal in the illumination space.

At this time, the user position determination unit 130 firstly detects movement of the user in the divided illumination space in which the user is positioned through the motion sensing unit 132, and when the motion is not detected, the communication terminal position sensing unit 134 To identify the position of the user's communication terminal in the divided lighting space.

In the case where only a motion detection sensor such as a PIR sensor is employed, the position of the user can be confirmed with only small movements. However, in some cases, the user may not be recognized when there is no movement for a predetermined period of time. .

According to such a configuration, it is possible to prevent malfunction of the illumination system due to the error of the user's position by performing not only the movement detection but also the detection of the position of the communication terminal of the user in order to confirm the user's position.

3 is a diagram illustrating an example of a user location confirmation state performed by the user location confirmation unit of FIG. FIG. 3 shows an example in which the user's location determination module and the motion detection module are installed in the LED lighting to confirm the user's location, respectively. In FIG. 3, the user location confirmation module and the motion detection module may be implemented by a Bluetooth communication module and an infrared communication module, respectively.

The user location illumination unit 140 illuminates the divided illumination space in which the user is located when the user's position is confirmed, with a second illuminance that is brighter than the first illuminance. At this time, the divided illumination space may be a partial area of the entire illumination space, and may be a preliminarily divided area so as to maximize the effect of the illumination control. In this case, the second roughness may be an effective roughness preset for effective illumination of the illumination space, for example, a maximum roughness of 100%.

According to this configuration, when the user enters the illumination space, the user performs weak illumination for the entire space and performs strong illumination only for the position of the identified user, thereby significantly reducing power consumption for the entire illumination space , It is possible to improve the identification of the user's surrounding area while preventing the inefficiency of frequently turning on or off the individual lights according to the user's position change.

Fig. 4 is a schematic diagram illustrating an example of illumination control performed by the illumination control system of Fig. 2; 4, when the temple enters the office in the state that the lighting is turned off, the entire lighting unit 120 lights up the entire indoor lighting lamp at a level of 20%, and the user's position lighting unit 140 An example of group control of illumination with 100% illumination is shown. At this time, the entire illumination unit 120 and the user location illumination unit 140 may be implemented as separate modules as a functional division, but they may be integrally implemented in one module.

In addition, the user location illumination unit 140 can stop illumination in the divided illumination space if the user's position is not confirmed again, even once the user's location is confirmed.

For this, the user location illumination unit 140 stops the illumination in the divided illumination space immediately when the position of the user's communication terminal is not confirmed. If the position of the user's communication terminal is detected, And to suspend the illumination in the divided illumination space if no movement of the user is detected during the waiting time.

Fig. 5 is a diagram showing an example of the illumination extinguishing performed by the user position illumination unit of Fig. 2; FIG. 5 shows an example in which the user's mobile terminal is located in the illumination space, but the movement of the user is not detected.

In FIG. 5, the LED illumination detects a registered mobile terminal through Bluetooth communication and performs dimming control of illumination. As in FIG. 5, the Bluetooth signal is detected but the light can be turned off if there is no signal detected by the PIR sensor.

This is for solving the problem that the lighting is paired with the mobile terminal when the person leaves the lighting space by placing the mobile terminal indoors. This is a solution to solve a problem that may occur when Bluetooth communication is employed together with the PIR sensor in order to solve the problem of low sensing sensitivity.

In addition, the entire illumination unit 120 can stop illumination of a predetermined divided illumination space when the movement of the user is detected for a preset time or more in the divided illumination space where the user's position is confirmed.

In this case, the predetermined divided illumination space may be a divided illumination space in which the position of the user is confirmed, and a divided illumination space not adjacent to the divided illumination space. FIG. 6 is a diagram showing an example of selective illumination lights performed by the overall illumination section 120 of FIG. 6 shows an example in which the lighting of the user's position and the divided lighting space at a long distance is turned off.

As shown in FIG. 6, when the user is located at a specific position over a certain period of time, the entire illumination unit 120 maintains illumination of 20% illumination for the area immediately adjacent to the user, . ≪ / RTI >

The predetermined divided illumination space may be a predetermined divided illumination space corresponding to the divided illumination space in which the position of the user is confirmed. FIG. 7 is a diagram showing another example of the selective illumination light extinguished by the overall illumination section 120 of FIG. FIG. 7 shows an example in which the illumination of the divided illumination space previously set corresponding to the user's position is turned off.

As shown in FIG. 7, when the user is located at a specific position over a certain period of time, the entire lighting unit 120 maintains 20% illumination of the user's location and the area between the entrance or user's location and the common facility However, it does not perform illumination for other areas.

According to such a configuration, it is possible to further reduce power consumption by turning off the illumination for a space that is less affected by movement or activity of the user.

When the illumination system is installed and used for a long period of time, there is a case that the originally intended illumination can not be performed due to the illuminance setting that was initially set in the illumination system due to the change of the illumination environment. In this case, the illuminance of the illumination system should be compensated by changing the illuminance setting of the illumination system.

To this end, the compensation data input unit 150 receives the illumination compensation position and the illumination adjustment input in the illumination space from the user's communication terminal. 8 is an example of a screen for inputting the current manager position to the compensation data input unit of FIG. 2 using a smartphone application (App).

8, the position of the manager may be automatically extracted from the position of the smartphone, and the communication terminal may be implemented as other types of communication terminals such as a remote control, not a smart phone. There will be.

The illuminance adjusting unit 160 adjusts the illuminance illuminance at the illuminance compensation position according to the illuminance adjustment input. The illuminance setting unit 170 illuminates the illuminance at the illuminance compensation position using the final illuminance adjustment input from the user's communication terminal Set the adjustment value.

9 is an example of an output screen of a smartphone app for performing illumination compensation in conjunction with the illumination controller of FIG. 2 and the illumination intensity setting unit. FIG. 9 shows an example in which the illuminance adjustment is stopped when the illuminance level measured by the smartphone does not reach the set illuminance level and the illumination illuminance gradually increases from 0 Ill to reach the set illuminance value.

At this time, the compensation data input unit 150 further receives the illuminance compensation position in the illumination space from the user's communication terminal and the illuminance adjustment information of the illuminance compensation position in which the illuminance adjustment value is preset, and the illuminance setting unit 160 The illuminance adjustment value at the preset illuminance compensation position may be further set to the illuminance adjustment value at the illuminance compensation position to be copied according to the illuminance adjustment information.

When the illuminance setting unit 160 changes the illuminance setting of the illumination system with respect to one illumination space in cooperation with the user's communication terminal, the illuminance setting data changed by the administrator's choice .

In this case, the administrator can apply the copy function to apply the set value of one illumination to the other illumination equally. According to such a configuration, it becomes possible to more easily perform the correction of the illuminance sensor for a plurality of illumination spaces in a similar illumination state.

10 is a schematic flowchart of a lighting control method according to an embodiment of the present invention. 10, the lighting control system senses the entrance of the user into the illumination space (S110), and illuminates the entire illumination space with the first illuminance (S120) when the user's entrance is sensed.

Then, the user's position in the entire illumination space is checked (S130). When the user's position is confirmed, the divided illumination space in which the user is located is illuminated with a second illuminance that is brighter than the first illuminance (S140).

Finally, the user's advancement in the illumination space is sensed (S150), and when the user's advance is sensed, illumination in the entire illumination space is stopped (S160).

11 is a flow chart illustrating in greater detail the steps of user location validation and user location illumination of FIG. 11, when the movement of the user is detected (S132) and the movement of the user is not detected in the divided illumination space in which the user is located, the position of the user's communication terminal in the divided illumination space is further checked (S134).

If the position of the communication terminal of the user is not confirmed, the illumination in the divided lighting space is stopped (S140). If the position of the communication terminal of the user is confirmed, the waiting time is waited for in advance (S136).

If the movement of the user is not detected during the waiting time, the illumination in the divided illumination space is stopped (S140).

12 is a view schematically showing a process performed by a user's communication terminal for illuminance compensation. 12, the user's communication terminal inputs the illuminance compensation position with the illumination control system (S210), and measures the illuminance at the input illuminance compensation position using the illuminance sensor provided in the communication terminal (S220).

The user's communication terminal compares the measured illuminance with a preset illuminance (S230), and if not, transmits the illuminance control input to the illumination control system (S230). This process is repeated until the measured illuminance and the preset illuminance match.

13 is a view schematically showing a process performed in the illumination control system for illumination compensation. 13, the illumination control system receives the illumination compensation position from the user's communication terminal (S310).

If the illuminance sensor of the user's communication terminal does not match the measured illuminance, the user's communication terminal will transmit the illuminance adjustment input, so the illumination control system will receive the illuminance adjustment input, The illuminance of the illumination system is then adjusted (S320).

This process is repeated until the illuminance measurement value measured by the user's communication terminal coincides with the set value. If the illuminance adjustment input is not received from the communication terminal of the user, The illuminance adjustment value of the illumination system is set based on the input illumination adjustment value finally input (S330).

Although the present invention has been described in terms of some preferred embodiments, the scope of the present invention should not be limited thereby but should be modified and improved in accordance with the above-described embodiments.
