Abstract

The present invention relates to a system and a method for controlling a lighting module for safety of a pedestrian. The system for controlling a lighting module comprises a plurality of lighting modules connected to a network. The plurality of lighting modules each comprise: a communications unit to detect a short-distance communication signal from a user terminal in which an application linked to the lighting modules is installed, and communicate with the user terminal or the lighting modules; and a control unit to increase an illumination intensity of the lighting modules when the short-distance communication signal is detected from the user terminal. According to the present invention, a pedestrian is detected at night to increase the illumination intensity of the lighting modules to illuminate the vicinity of the pedestrian with an illumination intensity higher than a normal illumination intensity to allow the pedestrian to see another pedestrian moving in a surrounding environment and on an opposite side, thus the pedestrian can relieve anxiety and maintain psychological stability when walking at night. Also, since the illumination intensity in the vicinity of the pedestrian is increased, potential criminals can be cautious and become reluctant to commit a crime, which greatly contributes to crime prevention. In addition, although the illumination intensity is increased by turning on an LED element, light distribution is adjusted to provide the pedestrian with a brighter environment without causing harm to a nearby residential space or a different space.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a lighting module control system for pedestrian safety,

The present invention relates to a lighting module control system for safety of pedestrians and a control method thereof, and more particularly, to a lighting module control system for sensing a user terminal installed with an application associated with a lighting module and raising the illuminance, .

Street lights and security lights are installed in India, residential areas, or parks at night for constant movement and security of pedestrians.

In order to secure pedestrians' safety, streetlights and security lights are on for a certain period of time, regardless of the presence of pedestrians, and many people point out the problem of power waste.

However, it is not possible to predict exactly when the pedestrian will walk, and even if it is predicted, it is essential to keep the streetlight at night because the streetlight or security light is effective in preventing crime as well as safety walking of the pedestrian.

On the other hand, if the illuminance of the street lamp or the security lamp is lowered, the safety walking of the pedestrian is lost, and if the high illuminance is maintained, the power is wasted.

In order to solve such a problem, security lamps such as sodium lamps or mercury lamps using high power or street lamps using LEDs having low power consumption are being replaced.

In recent years, techniques for increasing the illuminance by detecting pedestrians have been developed rather than being constantly turned on with a constant illumination. In other words, if lighting is turned on at low illuminance usually and pedestrians are detected, a plurality of street lights can be individually controlled to illuminate the illuminance higher than usual illumination to secure safety of pedestrians and reduce power waste Is being developed.

However, the standard of safety walk that each pedestrian feels is different here, and it is difficult to satisfy all the pedestrians by such a technology development.

That is, there is a need for a security lamp and a streetlight control technique for pedestrians who are anxious about walking at night. In order to utilize these technologies, pedestrians need to visit the municipality of their residence or download the application through online and register the own number of the terminal with the local government so that the security light or streetlight recognizes the pedestrian terminal Research is needed.

The technology to be a background of the present invention is disclosed in Korean Patent Laid-Open No. 10-2012-0136808 (published on December 30, 2012).

SUMMARY OF THE INVENTION The present invention is directed to a lighting module control system and a control method thereof for detecting a user terminal installed with an application associated with a lighting module to raise the illuminance.

According to an aspect of the present invention, there is provided an illumination module control system including a plurality of illumination modules connected to a network, wherein the plurality of illumination modules include a plurality of illumination modules, A communication unit for sensing a communication signal and communicating with the user terminal or the lighting module, and a control unit for enhancing the illuminance of the lighting module when a short distance communication signal is sensed from the user terminal.

Wherein the illumination module includes a first LED element spaced apart from the first LED element, a second LED element having a higher illuminance or different illumination color temperature than the first LED element, and the controller illuminates the second LED element, The illuminance can be increased.

The second LED element may be irradiated in a linear light form.

And a motion sensing unit for sensing a motion of a second pedestrian moving in a direction of a first pedestrian carrying the user terminal through an IR sensor mounted on the plurality of illumination modules.

The communication unit may communicate between the lighting modules so that the IR sensor of the lighting module located in the traveling direction of the first pedestrian operates when the short distance communication signal is sensed from the user terminal.

When the second pedestrian is sensed through the IR sensor, the controller may increase the illuminance of one or more lighting modules located between the first pedestrian and the second pedestrian.

The lighting module includes: a recognition unit for recognizing a face of the second pedestrian through a camera mounted; And a judging unit for comparing the previously stored face with the recognized face of the second pedestrian to determine whether or not the face of the second pedestrian matches the face of the second pedestrian, The notification signal can be transmitted to the terminal.

According to another embodiment of the present invention, there is provided a control method of a lighting module control system including a plurality of lighting modules connected by a network, wherein the plurality of lighting modules includes a plurality of lighting modules, Sensing a signal and communicating with a user terminal or with a lighting module; And raising the illuminance of the lighting module when a short distance communication signal is sensed from the user terminal.

According to the present invention, since the lighting module detects a pedestrian at night and illuminates the periphery by changing the color of the illumination, the surrounding environment and the appearance of the other pedestrian moving on the opposite side can be seen It is possible to relieve anxiety and to have a sense of psychological stability when walking at night at night. As the illuminance around the pedestrian increases, preliminary offenders become alert and hesitate to commit crime, which can have a great effect on crime prevention.

In addition, the illumination of the LED device makes the illuminance brighter than the standard, but it can provide a brighter environment for night walkers without damaging the side residential space and other spaces by adjusting the light distribution.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

1 is an exemplary diagram of a lighting module control system according to an embodiment of the present invention.

1, the lighting module control system includes a plurality of lighting modules 100 (100-1, 100-2, 100-3, 100-4, 100-5, and 100-6).

Here, the lighting modules 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6 are not limited to the positions or the numbers in the display of codes for the sake of convenience of description.

The plurality of lighting modules 100-1, 100-2, 100-3, 100-4, 100-5, and 100-6 detects a local communication signal of a user terminal (not shown) carried by the first pedestrian to further enhance illumination. In this case, the local communication signal of the user terminal indicates a local communication signal transmitted through an installed application when an application interlocked with the lighting module is installed. In FIG. 1, the local communication signal is assumed to be a Bluetooth signal.

That is, the lighting module 100 can sense the near-field communication signal and control the illumination intensity only when an application (hereinafter referred to as "application") interlocked with the lighting module is installed in the terminal of the user to transmit the near- have.

When the first pedestrian passes the front of the lighting module 100-2 with the user terminal installed with the application, the lighting module 100-2 detects the short-range communication signal transmitted through the application of the user terminal, Or illuminates the additional illumination device, thereby illuminating the first pedestrian with a brighter illumination.

At this time, the illumination module 100-2 increases the illuminance to the maximum and the illumination module 100-3 gradually increases the illuminance corresponding to the traveling direction of the first pedestrian.

At this time, the illumination module 100-3 can increase the illuminance gradually according to the local communication signal of the user terminal to be sensed or receive the control signal that the illuminance is gradually increased from the illumination module 100-2.

If the first pedestrian moves and is located between the lighting module 100-3 and the lighting module 100-4, the lighting module 100-3 and the lighting module 100-4 can be made to gradually increase the illuminance On the other hand, the illumination module 100-2 can gradually reduce the illuminance to the original illumination state as the local communication signal of the first pedestrian user terminal to be sensed becomes weaker and weaker.

2 is a configuration diagram of a lighting module of a lighting module control system according to an embodiment of the present invention.

The lighting module 100 according to an exemplary embodiment of the present invention may include a communication unit 110 and a control unit 120 and may further include a motion sensing unit 130, a recognition unit 140, and a determination unit 150.

First, the communication unit 110 detects a local communication signal from a user terminal installed with an application, and performs communication with the user terminal or the lighting module.

At this time, the short-range communication signal uses short-range wireless communication such as Zigbee, Bluetooth, and NFC in the form of wireless communication, and is not limited to a specific wireless communication network.

And communication between the lighting modules may utilize wired networks, wireless networks, infrared communications, fiber optic communications, or computer networking technologies, i.e., Ethernet technologies.

The control unit 120 maintains the illuminance of the illumination module 100 constant at night. When the user senses a local communication signal from the user terminal, the control unit 120 increases the illuminance of the LED module of the illumination module 100, It lights up.

In addition, the controller 120 can increase the illuminance of the illumination module 100 when it senses the second pedestrian in the direction of the first pedestrian holding the user terminal from the IR sensor.

Next, the motion sensing unit 130 senses the movement of the pedestrian moving around the lighting module through the mounted IR sensor. Particularly, according to the embodiment of the present invention, the motion sensing unit 130 can sense the moving direction of the second pedestrian moving in the direction of the first pedestrian holding the user terminal.

The IR sensor indicates an infrared ray sensor. Upon receiving an operation signal from the communication unit 110, the IR sensor starts to detect movement.

Here, the IR sensor is an infrared sensor for sensing movement, and may be replaced with another sensor device capable of motion detection.

If the controller 120 does not detect the first pedestrian or the second pedestrian, the controller 120 may return the illuminance of the illumination module 100 to the existing illuminance.

The recognition unit 140 recognizes the face of the second pedestrian through the mounted camera. That is, the recognition unit 140 can extract the second pedestrian from the photographed image to recognize the face, and extract the main feature of the recognized face to generate the face recognition information.

Such a face recognition technology is a known technology and can be easily implemented by those skilled in the art, and a detailed description thereof will be omitted.

The determination unit 150 compares the face of the pre-stored criminals with the face recognition information of the recognized second pedestrian to determine whether or not they match. That is, the determination unit 150 may compare the face information of the pre-stored criminals based on the face recognition information received from the recognition unit 140 to determine whether they match.

The determination unit 150 may compare the face of the second pedestrian using a separate database storing the face of the offender to determine whether or not they match.

Here, the separate database in which the criminal's face is stored may be embedded in the lighting module 100 or may be stored in a separate device. At this time, the pre-stored face may include a violent offender or a sex offender whose personal image is disclosed, or may include an open witness.

In addition, when the user designates a photograph stored through the application of the user terminal, the determination unit 150 may determine whether or not the face of the second pedestrian matches the face of the stored photograph.

3 is a view showing a structure of an LED lighting device mounted on a lighting module according to an embodiment of the present invention.

3, the LED lighting device mounted on the lighting module 100 according to the embodiment of the present invention may be divided into a first LED device group and a second LED device group.

The first LED element is irradiated in a form that the light spreads in all directions while the second LED element is irradiated in the form of a linear light with a lighted bottom of the foot than the air hole so that a sufficient amount of light can be transmitted where necessary.

That is, the second LED element is an illumination element provided in addition to general illumination constituting only the first LED element, the structure being formed so that the light does not spread but directed downward.

In addition, the second LED element may have a color temperature different from that of the first LED element. That is, the second LED element may be lit in blue or white.

The illumination devices spaced apart as shown in FIG. 3 are one example, but the illumination devices may be installed in various structures or shapes.

Meanwhile, increasing the illuminance of the illumination module 100 throughout the specification means that the illuminance of the existing first LED element is raised higher than usual illuminance, and the case of having a specific function like the second LED element of FIG. 3 And further lighting the second LED element to increase the illuminance.

Hereinafter, a control method of a lighting module control system including a plurality of network-connected lighting modules according to an embodiment of the present invention will be described with reference to FIG. 4 and FIG. 5B.

5A is a view for explaining a method of operating a lighting module control system according to an embodiment of the present invention, and FIG. 5B is a view for explaining a method of controlling the lighting module control system according to an embodiment of the present invention. Is an exemplary diagram illustrating a method by which a lighting module control system according to an embodiment of the present invention operates at a range.

First, the plurality of lighting modules 100 detects a short-range communication signal from a user terminal installed with an application interlocked with the lighting module, and performs communication with the user terminal or another lighting module (S410).

At this time, it is assumed that a pedestrian possessing a user terminal equipped with an application interlocked with the lighting module is a first pedestrian.

The lighting module 100 senses a change in the local communication signal of the user terminal held by the first pedestrian and can predict the traveling direction of the first pedestrian through communication with another lighting module. The illumination module 100 can transmit a control signal to gradually increase the illuminance to another illumination module installed in the predicted direction when the traveling direction of the first pedestrian is predicted.

The communication method between the lighting modules 100 is not limited to a specific method but may be selected by a manager as a communication method suitable for the structure of the alley where the lighting module 100 is installed and the surrounding situation.

Next, when the lighting module 100 senses a local communication signal from the user terminal, it controls the illuminance of the lighting module (S420).

When the lighting module 100 senses a short-range communication signal (indicated by a Bluetooth signal in FIG. 5A) of the user terminal, it gradually increases the illuminance and when the strongest short-range communication signal is detected corresponding to the short- have.

That is, as shown in FIG. 5A, the illumination module 100-2, which detects the strongest nearest communication signal nearest to the first pedestrian, maximizes the illuminance and detects a lower-level communication signal than the illumination module 100-2 The lighting module 100-3 can gradually increase the illuminance and control the illuminance corresponding to the near-field communication signal.

When the lighting module 100 detects a short-range communication signal from the user terminal, the lighting module 100 communicates between the lighting modules so that the IR sensor of at least one lighting module located in the first pedestrian direction operates (S430).

5A, when the lighting module 100-2 detects a signal from the user terminal of the first pedestrian, the lighting module 100-2 detects at least one lighting module 100-3 , 100-4, 100-5, and 100-6, respectively, through the communication between the lighting modules so that the IR sensor can operate.

That is, the IR sensor installed in the lighting module does not detect all the pedestrians, but operates only when receiving an operation signal through communication between the lighting modules to detect movement. Among them, the second pedestrian moving in the first pedestrian direction Can be detected. Here, the communication method between the lighting modules is not limited to the specific communication method as in step S410.

Next, the lighting module 100 senses the movement of the second pedestrian moving in the direction of the first pedestrian through the mounted IR sensor (S440).

When the second pedestrian moving in the direction of the first pedestrian is detected through the IR sensor mounted on the lighting module, the lighting module sensing the second pedestrian increases the illuminance, and the first pedestrian moves the position and face of the second pedestrian It is possible to transmit a control signal for raising the illuminance to one or more lighting modules located between the second pedestrian and the first pedestrian so as to be able to confirm.

5A, the illumination module 100-2 transmits an IR sensor operation signal to the illumination modules 100-3, 100-4, 100-5, and 100-6, and the illumination module 100-5 When detecting the second pedestrian moving in the direction of the one pedestrian, the lighting module 100-5 increases the illuminance of the illumination and controls the lighting module 100-5 installed between the lighting module 100-5 and the first pedestrian -4, and 100-3) to gradually increase the illuminance of the illumination.

Here, the control signal may be transmitted from the lighting module 100-5, which senses the second pedestrian, to the lighting modules 100-4 and 100-3 installed between the positions of the first pedestrian, , And 100-3, the control signal may be transmitted to increase the illuminance of only one illumination module.

These settings can be changed by the administrator later.

In this case, the illumination module may increase the illuminance in proportion to the intensity of the short-range wireless signal of the user terminal sensed in step S420.

For example, as shown in FIG. 5B, when the lighting module 100-1 detects a short-range communication signal generated in a user terminal installed with an application carried by a first pedestrian at a crossing of two or more alleys, -1) maximizes the illuminance and the illumination module 100-2 gradually increases the illuminance.

At this time, the illumination modules 100-1 and 100-2 may sense all of the short-range communication signals generated by the user terminal and increase the illumination depending on the intensity of the short- -1) detects the local communication signal and transmits a control signal to gradually increase the illuminance to the lighting module 100-2 located in the moving direction of the user.

When the first pedestrian moves in the proceeding direction and the lighting module 100-1 does not detect the local communication signal of the user terminal, the illumination module 100-2 gradually reduces the illuminance and the lighting module 100-2 detects the local communication signal of the user terminal Raise illumination to the brightest. When the first pedestrian is positioned in front of the lighting module 100-2, the lighting modules 100-3, 100-4 and 100-5 closest to the lighting module 100-2 also gradually increase the illuminance. At this time, if the first pedestrian further moves in the traveling direction and senses the local communication signal of the user terminal from the lighting module 100-5, the lighting module 100-5 brightens the illumination to the brightest, , 100-4), and the lighting module 100-2 gradually reduces the illuminance to maintain the existing illuminance.

On the other hand, when the lighting module 100-1 senses the local communication signal of the user terminal, the IR sensor operation signal is transmitted to the lighting module located in the user's traveling direction. In the case of the intersection, And transmits an IR sensor operation signal to the installed illumination modules 100-2, 100-3, 100-4, and 100-5.

At this time, the illumination module 100-1 sends one or more illumination modules 100-2, 100-3, 100-4, 100-5, 100-6, and 100-7, Can be transmitted.

The illumination modules 100-2, 100-3, 100-4, 100-5, 100-6, and 100-7 that have received the IR sensor operation signal from the illumination module 100-1 move in the first pedestrian direction The second pedestrian can be detected.

Referring to FIG. 5B, the lighting module 100-7 detects a second pedestrian moving in a direction in which the first pedestrian is located. At this time, the lighting module 100-7 raises the illuminance brighter than the existing illuminance.

The lighting module 100-7 then transmits a control signal to the at least one lighting module among the lighting modules 100-2, 100-5, and 100-6 located between the second and the first pedestrian .

Then, the lighting module 100 recognizes the face of the second pedestrian through the mounted camera (S450).

The lighting module 100 recognizes the face of the second pedestrian through the photographed image and separately extracts the recognized face portion to select a point on the main portion of the face. Then, the illumination module 100 divides the contour of the face by Delone triangulation, which divides the selected triangle into smaller triangular angles when dividing the space by connecting triangles to the selected points. The lighting module 100 converts the divided pieces into three dimensions, and adjusts the brightness according to the importance of the facial feature, and adjusts the photograph to a front view based on the previously selected point.

That is, the illumination module 100 can convert the face of the second pedestrian, which is photographed regardless of the photographing angle, to an angle that allows the comparison to be easily performed after recognizing the face, and then reconstruct the face.

This method is an example of a method of recognizing the face of the second pedestrian and converting it to the front face for comparison, but is not limited thereto.

Next, the lighting module 100 may compare the face of the pre-stored criminal with the face of the recognized second pedestrian (S460).

When the lighting module 100 compares the information of the previously stored criminal's face with the recognized face information of the second pedestrian, and if the matching value is equal to or greater than the reference value, the lighting module 100 compares the second pedestrian with the pre- . Here, the reference value is a minimum value at which it is determined that the faces of two images are the same person, and can be adjusted or changed by the administrator.

In this case, if it is determined that the face of the criminal and the face of the second pedestrian coincide with each other, the lighting module 100 notifies the terminal of the first pedestrian that the second pedestrian is the criminal, A criminal notification signal can be transmitted.

On the other hand, if the first pedestrian designates a portrait photograph stored through the application, the lighting module 100 may determine whether the second pedestrian is the same person as the designated person.

That is, in step S410, the user terminal may transmit the local communication signal through the application of the first pedestrian and simultaneously transmit the designated portrait photograph to the lighting module 100. [

5B, the lighting module 100-1 is connected to the illumination modules 100-2, 100-3, 100-4, 100-5, 100-6, and 100-7 located in the first walking direction, It is possible to transmit the information of the person picture specified with the operation signal.

Then, the lighting module 100-7, which senses the second pedestrian through the mounted IR sensor, can compare the information of the designated person's photograph received and the information of the second pedestrian face to determine whether or not they match.

If it is determined that the information of the designated person's photograph matches the second pedestrian's face information, the lighting module 100-7 transmits the notification signal or the photographed image of the second pedestrian to the user terminal, The lighting module 100-2 may transmit the matching signal to the nearby lighting module 100-1 and the image of the photographed second pedestrian and the lighting module 100-2 may transmit the notification signal or the image of the second pedestrian to the user terminal.

As described above, according to the embodiment of the present invention, since the lighting module detects the pedestrian at night and illuminates the surroundings by raising the illuminance higher than the existing illuminance, the surrounding environment and other pedestrians moving on the opposite side can be seen, Can relieve anxiety and provide a sense of psychological stability when walking at night. As the illuminance around the pedestrian increases, preliminary offenders become alert and hesitate to commit crime, which can have a great effect on crime prevention.

In addition, the illumination of the LED device makes the illuminance brighter than the standard, but it can provide a brighter environment for night walkers without damaging the side residential space and other spaces by adjusting the light distribution.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
