Wireless lighting control device and its method

The present invention relates to a wireless lighting control device, and more particularly, to a wireless lighting control device and a method that can control the lighting automatically through a wireless communication between a plurality of lights installed in a specific space.

In general, in a large space with a large number of lights (for example, underground parking lot, tunnel, building passageway, emergency staircase, etc.), all the lights are always turned on so that the entire space can be illuminated. Therefore, in order to improve this, a method of installing a sensor in each light and allowing each sensor to sense a moving object has been implemented so that the light is turned on only when there is an object.

However, when the lighting is turned on only where the object is located by the sensor as described above, the lighting is turned on only at the corresponding position, which makes it difficult to identify the surrounding area to be moved. In addition, when traveling in a vehicle such as an underground parking lot or a tunnel and moving at a high speed, a problem occurs that the lighting does not play a role because the lighting speed cannot be followed by the sensor.

Therefore, there is a demand for a method for effectively illuminating the space according to the movement of an object without always lighting the light in a specific space.

An object of the present invention, when detecting the object by a sensor installed in the light, by transmitting a control signal to the surrounding light to turn on the ambient light to effectively control the lighting in the space in which the object is moving And it provides a method.

In addition, an object of the present invention is to calculate the speed of the object moving in the space, and by controlling the area of the light to be illuminated according to the calculated speed wireless lighting control that can effectively perform the lighting control in the space the object is moving An apparatus and a method thereof are provided.

In this case, the controller calculates a moving speed of the object based on a difference between a time of detecting an object from the sensor and a time of receiving a control signal through the wireless receiving unit, and transmits the moving speed through the wireless transmitting unit according to the calculated moving speed. Characterized in that the output power of the control signal to adjust.

In addition, the control unit is characterized in that for controlling the illuminance of the illumination in accordance with the reception intensity of the control signal received through the wireless receiving unit.

On the other hand, the device is characterized in that the illumination is set differently between the illumination is turned on in accordance with the signal sensed from the sensor and the illumination is received by receiving a control signal through the wireless receiver.

The apparatus may be configured to differently set a lighting time between the lighting that is turned on according to the signal sensed by the sensor and the lighting that is turned on by receiving a control signal through the wireless receiver.

In order to achieve the above object, the wireless lighting control method according to the present invention comprises the steps of: initializing the mode of the wireless lighting control device to a reception mode; Receiving a signal sensed according to the movement of the object from the sensor to turn on the lighting of the location; Switching a mode of the wireless lighting control device to a transmission mode; And generating a control signal from a control unit and transmitting the generated control signal through a wireless communication means.

The present invention proposes a method that can effectively turn on the lighting according to the movement and speed of the object for the power saving of the lighting such as the always-on lighting, such as building passages, emergency stairs, underground parking lot.

That is, the present invention includes a wireless lighting control device provided with a sensor and a wireless transmitting / receiving means for identifying movement of an object in each of a plurality of lights installed in a specific space. When the movement of the object is identified by the provided wireless lighting control device, the control signal is transmitted to the adjacent area by controlling the lighting of the lighting at the corresponding position and the lighting in the adjacent area at the same time.

In addition, when the movement of the object is detected in the light receiving the control signal, the movement speed of the object is calculated using the time when the control signal is received and the time when the movement of the object is detected. By adjusting the output power of the control signal transmitted from the corresponding area according to the calculated moving speed of the object, it is possible to effectively illuminate by widening the range of the lighting lamp that is turned on when the object moves at a high speed.

DETAILED DESCRIPTION Hereinafter, a detailed description of a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a view showing the concept of a wireless lighting control system according to the present invention. Referring to FIG. 1, when a plurality of lamps 120 are installed in a specific space (eg, underground parking lot) 100, each lamp 120 is provided with a lighting control device to be described later according to the present invention. The control unit detects the movement of the object and provides effective lighting control.

That is, when the object enters the specific space 100 through the doorway 110, the lighting control device installed in the adjacent A14 lamp 120 detects the movement of the object and turns on the A14 lamp 120. . At this time, the lighting control device installed in the lamp 120 of A14 transmits a control signal using a wireless communication means. The control signal transmitted as described above is received by the lighting control apparatus installed in the adjacent A13, A10 and A15 lamps 120, and lights up the corresponding lamps (ie, A13, A10 and A15 lamps) 120. Let's do it.

Each of the illuminated lamps 120 is turned on for a predetermined time according to a preset timer value, and the lighting time of the lamp 120 that is directly sensed and the lighting time of the lamp 120 that is turned on by receiving a control signal are different from each other. Can be set. In addition, the lighting lamp 120 which is already turned on according to the movement of the object may be automatically flashed by setting it to be dimmed for a predetermined time.

Therefore, the illumination lamp 120 in the area where the object is located and the illumination lamp 120 in the adjacent area are sequentially turned on according to the movement of the object, thereby enabling efficient lighting control in the space 100. .

Meanwhile, according to the present invention, the speed of the moving object is calculated, and the faster the moving speed of the object, the higher the transmission power of the control signal transmitted from each of the lamps 120 is transmitted, thereby increasing the transmittance of the lamp 120 in a wider area. Will light up.

For example, when the object proceeds from the area of the A14 lamp 120 to the area of the A10 lamp 120, first, the lighting control device installed in the A14 lamp 120 detects the movement of the object and turns on the A14 lamp 120. . In addition, as described above, in order to turn on the lamp 120 of the adjacent area, a control signal is transmitted. When the moving speed of the object is slow, the control signal transmits a small output and transmits the moving speed of the object. If it is early, the transmission signal of the control signal is increased.

Therefore, for example, when the moving speed of the object is slow, since the transmission power output from the light control device of the A14 lamp 120 is small, the control signal may be received only by the immediately adjacent lamps A13, A10, and A15 lamps 120. It becomes possible. On the other hand, when the moving speed of the object is high, since the transmission power output from the lighting control device of the A14 lamp 120 is large, the adjacent lamps 120, A13, A10, A15 lamp 120, as well as A9, A6 In addition, the A11 lamp 120 may receive and control a control signal. Therefore, when the moving speed of the object is fast, the reception area of the control signal is widened by that much, and thus the lighting is turned on for a wider area, thereby enabling efficient lighting control.

Meanwhile, in the present invention, the moving speed of the object is calculated using a difference between the time of detecting the object from the sensor and the time of receiving the control signal transmitted from the adjacent lighting control device.

For example, assuming that an object passes near the A14 lamp 120 and passes near the A10 lamp 120, when the object passes near the A14 lamp 120, the A14 lamp 120 stops moving the object. It detects light and turns on control signal. The A10 lamp 120 receives the control signal transmitted from the A14 lamp 120 and turns on, and when the object passes the vicinity of the A10 lamp 120, the A10 lamp 120 directly detects the movement of the object by the sensor. In this case, the faster the moving speed of the object is, the smaller the time difference between the time of detecting the object in the lighting control device of the A10 lamp 120 and the receiving time of the control signal transmitted from the lighting control device of the A14 lamp 120 is smaller. do. Therefore, in each lamp 120, the moving speed of the object can be calculated by the following Equation 1.

Figure 112010047337111-pat00001

When the moving speed of the object is calculated by Equation 1, the transmission output value of the control signal transmitted from the lighting control device of the A10 lamp 120 is adjusted according to the calculated speed value. For example, when the moving speed of the object measured by the lighting control device installed in the A10 lamp 120 is slower than the set value, the transmission power transmitted by the lighting control device of the A10 lamp 120 is lowered to directly adjacent the lamps A9, A6, Only the A11 lamp 120 may receive the control signal. On the other hand, when the moving speed of the measured object is faster than the set value, by increasing the transmission output transmitted from the lighting control device of the A10 lamp 120, as well as the immediate adjacent lamp 120 A9, A6, A11 lamp 120 as well. Furthermore, the A5, A2, and A7 lamps 120 may also receive and turn on control signals. Therefore, even if the object moves quickly, the lighting is turned on for the wider area, thereby enabling effective lighting control.

Hereinafter, the structure of a lighting control device installed in each of the lamps 120 according to the present invention with reference to FIGS. 2 and 3 will be described in detail.

2 is a block diagram showing the structure of a wireless lighting control apparatus according to the present invention. 2, the wireless lighting control apparatus 200 according to the present invention includes a wireless transmitter 210, a wireless receiver 220, a power supply 230, a controller 240, an illuminator 250, and a sensor 260. It can be configured as.

The sensor 260 detects a movement of an object and transmits the sensed signal to the controller 240. The controller 240 lights the lamp of the lighting unit 250 according to the sensing signal received from the sensor. The lighting unit 250 is composed of a lighting (for example, LED lighting) and other lighting accessories, and receives power from the power supply 230 to be turned on.

Meanwhile, according to the present invention, the control unit 240 receives a signal sensed by the sensor 260, and then generates a control signal for turning on an adjacent lamp and transmits it through the wireless transmitter 210. In this case, the adjacent wireless light control device 200 receives the transmitted control signal through the wireless receiver 220. The control signal received through the wireless receiver 220 is transmitted to the control unit 240, the control unit 240 is turned on the lighting of the lighting unit 250 in accordance with the control signal.

In addition, as described above, the controller 240 determines a difference value between the reception time of the signal detected from the sensor 260 and the reception time of the control signal received from the wireless receiver 220 according to an embodiment of the present invention. The moving speed of the object is calculated. Thereafter, the control signal generated by the controller 240 is transmitted through the wireless transmitter 210 as a transmission output determined according to the speed value calculated as described above.

3 is a diagram illustrating a physical connection relationship of a wireless lighting control apparatus according to an embodiment of the present invention. Referring to FIG. 3, the AC power supply 300 (eg, AC 220V) is converted into a DC power supply of DC 8V to 48V (eg, 12V or 24V) through the adapter 310 and supplied to the control module 320. The control module 320 turns on the LED lamp 350 by providing the control DC power to the LED lamp 350 by a signal sensed from the sensor 340 or a control signal of an adjacent lamp received through the antenna 330. Let's do it. In addition, as described above, the control module 320 generates a control signal and transmits the control signal to the adjacent lamp through the antenna 330.

Hereinafter, a wireless lighting control procedure according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5.

4 is a flowchart illustrating a wireless lighting control procedure according to an embodiment of the present invention. Referring to FIG. 4, basically, the apparatus for controlling a wireless light according to the present invention is set to a reception mode for waiting for a control signal (S401). In the receiving mode, the sensor continues to sense whether there is a moving object. As a result of sensing of the sensor, when a moving object is detected (S402), the corresponding lamp is turned on (S403).

In this case, the controller switches the preset reception mode to the transmission mode (S404), generates a control signal, and transmits it to the adjacent lamp (S405).

Meanwhile, as shown in FIG. 4, the wireless transmitter 210 and the wireless receiver 220 of the wireless lighting control device installed in the lamp according to the present invention are always kept in the reception standby state and the movement of the object is sensed. It is desirable to only switch to the transmission mode to transmit control signals to the device. As such, by using a single mode of a transmission mode or a reception mode other than the transmission / reception mode, it is possible to prevent interference or noise and data errors of signals transmitted between the wireless lighting control devices.

5 is a flowchart illustrating a wireless lighting control procedure according to another embodiment of the present invention. Referring to FIG. 5, as described above with reference to FIG. 4, the wireless lighting control device is basically set to a reception mode in a standby state (S501). At this time, upon receiving the control signal transmitted from the adjacent wireless lighting control device (S502), the lighting is turned on (S503) according to the level of the received signal. For example, when the reception intensity of the control signal is large, the moving object is determined to be in close proximity, and the illumination of the lamp is turned on to increase. It can be turned on by lowering it. That is, more effective lighting control is possible by adjusting the illuminance of the lighting lamp that is turned on according to the reception sensitivity or the reception level of the received control signal.

When the corresponding lighting is turned on by the received control signal as described above, when the moving object is directly detected by the sensor (S504), the illuminance level of the lighting is changed or the lighting time is readjusted. In addition, as described above, the moving speed of the object is calculated using the time difference between the received control signal and the sensed signal according to the present invention (S505).

Thereafter, the controller switches the preset reception mode to the transmission mode (S506), generates a control signal, and transmits the control signal to the adjacent lamp (S507). At this time, the transmission power of the control signal is adjusted and transmitted according to the calculated speed value.

At this time, the distance between the lights may be different, so keep the switch on only for the lights within 10m.

2. When receiving a control signal, the lighting can be controlled by sensing the level of the received signal. In this way, a dip switch for adjusting the reception level in four levels may be additionally installed in the wireless lighting control device. In this case, the maximum transmission / reception distance may be designed to be 35m, and the reception level of the four steps may be set to 35m, 25m, 15, and 7m. The default setting is 7m for lights installed in parking spaces and 15m for lights installed in driving spaces.

3. Dimming can be set in 8 steps from 0% ~ 100% when lighting each lighting. The lamp, which receives the control signal wirelessly, is turned on with 100% illumination and immediately dimmed. In this case, the dimming time is applied for 2 minutes in the case of a lighting lamp lit by sensing of the object, and the lighting lamp received by receiving a control signal is applied in 1 minute.

4. Install the two switches in each wireless lighting control device. The first switch sets functions such as speed detection (1), illuminance detection (2), reception level settings (3 to 4), and the second switch sets dimming level settings (1 to 3) and spares (4). Set the function.
